Environmental Reclamation of the 32 Acres behind the General Office Building March. 23, 2010 Rev-I Environmental Reclamation of 32 Acres behind General Office Building IS Introduction This paper discusses the project plan of removing excavation spoils from the 32 acres behind the General Office Building and contains a specific environmental plan for the initial phases of this project. The project plan, environment plan, and the contract for services have been reviewed in whole or in part by representatives of the Legal, Environmental, Budget and Radiation Protection Departments from Seabrook and our corporate offices (see attachment 1).Summary During the construction of Seabrook Station and a few projects since (i.e. Dry Fuel Storage), excavation spoils have been stock piled on the 32 acres behind the General Office Building (GOB). This, approximately 3 million tons of excavation, has disturbed the land from its original and natural environment. The fill is comprised of soils, different sized bedrock spoils, and boulders to large to crush and some amount of construction spoils of varying types (i.e. asphalt, concrete, etc...). The vendor is removing all material encountered including construction spoils.If at anytime time during the project unexpected materials are unearthed the project will be halted.Maintenance Services will be contacted and appropriate measures will be taken to determine if environmental or personnel hazards are present The effort to reclaim this land will be a 3 phase project. The 32 acres will be split in half by a north/south line. The first phase is to remove the fill to approximately a 15 foot depth on the westerly 16 acres.Phase 2 will be to remove fill to a depth of approximately 15 feet on the easterly 16 acres. This process O will continue until the area is returned to its original elevation. Phase 3 would be to add topsoil, grade and contour the area, and establish natural flora to the area by seeding and planting as required.This paper is to discuss the first and second phases of the project. The third phase will require a formal reclamation plan and would not be started until at least 2013.Radiological Considerations The Radiological Protection (RP) Department has taken several soil samples from the area identified as Phase 1 and analyzed these samples for radioactivity. In addition, direct survey measurements were taken at the site where Phase 1 of excavation removal will occur. The results are documented in Health Physics Study/Technical Information Document (HPSTID) 10-003 (see attached), Assessment of Soil Removal from Rock Pile Area South of General -Office Building (Phase One). .A review of these samples and surveys indicates no presence of radioactive material other than natural.background radioactivity and in conjunction with Seabrook Station Radiation Protection (SSRP) Manual procedure RP 13.1, Radiological Controls for Material, it is reasonable and a business case exists to remove this material in an effort to reclaim the land.Once the project commences the RP department shall be notified of any new materials that are brought into the project area that could potentially be removed from site. Additionally, RP shall be notified prior to the commencement of Phase 2 of excavation spoil removal.2 Environmental Reclamation of 32 Acres behind General Office Building Security Increased and steady truck traffic at the south gate and in and out of the GOB parking lot presents a number of safety concerns. Some of these safety concerns include increased opportunities for falling debris to hit someone and debris falling onto the road way and/or the GOB parking lot entrance causing pedestrian and traffic hazards.In an effort to have this increased traffic avoid the south gate and the GOB parking lot altogether, Security suggests the vehicles enter the fill site via F lot. The trucks would drive up the south access road, turn right onto the Hannah Foods road and left into F lot. A second, active gate will be installed at the rear of F lot allowing the trucks to access the fill area. The trucks would then leave the fill area the same way they entered, through F lot..By utilizing this traffic pattern the trucks will avoid all contact with the south gate and the GOB parking lot thus eliminating many of the safety concerns for site employees and their vehicles. At the end of the work day the driver of the last truck leaving will be required to close and lock both F-lot gates thus closing off the fill area from public access.Prerequisites to use the F lot for access: 1) Construction of active gate at the rear of F lot to facilitate access to the pit area.2) Locks installed on the gates. (Keyed or combination locks are acceptable with the necessary access provided to security).

3) Installation of appropriate number of jersey barriers placed at the back of the dirt road connecting the pit area and the GOB parking lot. These barriers will block access at the pit side of the dirt road and not allow anyone to drive down the dirt road toward the GOB parking lot.4) Instructions and expectations to vendor requiring the gates be opened and closed and locked as appropriate.

Licensing/Environmental See the Environmental Plan for the Removal of Excavation Material Stock Piled on 32 Acres behind the General Office Building during Construction of the Site attached to the end of this document.Financial Contract for this project is 02218558.The contract with Seabrook Trucking Center calls for $1.35 per cubic yard.The contract ends on August 17, 2012.Seabrook Truck is responsible for all taxes on the removal of gravel and permits required for this project.Cost for environmental sampling will be shared by Nextera Energy-Seabrook and Seabrook Truck Profit realized by Nextera Energy-Seabrook will be shared accordingly with Joint Owners Legal The contract agreement between Nextera Energy-Seabrook and Seabrook Truck has been reviewed by General Counsel Legal and found to be satisfactory. A review of zoning in the area of the project has been reviewed and found to have no issues (see Attachment 7).General Counsel deferred to on the Juno Environmental Services (JES) part of the Business Strategy and Policy Group for review and approval of the Environmental Sampling Plan. JES has reviewed the contract from Golder Associates (Attachment

2) for sampling and found it to be satisfactory.

3 Environmental Plan For the Removal of Excavation Material Stock Piled on 32 Acres behind the General Office Building during Construction of the Site March 23, 2010 Rev-1 Environmental Reclamation of 32 Acres behind General Office Building 1.0 Introduction During construction of Seabrook Station (SBK) excavation spoils was stock piled on the 32 Acres behind the General Office Building (see attachment 5). There are approximately 3 million tons of fill in this area.At some point in the life span of SBK this area would need to be reclaimed and returned to its natural state as it existed prior to the erection of this facility.The SBK site is bordered on the east by an extensive salt marsh and is located on a point called "The Rocks" between two small tidal estuaries, the Brown's River and the Hunt's Island Creek. Adjoining the site is abroad, flat marsh zone in the north east and south identified as Hampton Flats with an elevation of approximately +4 feet mean sea level (msl). The normal high tide water level at Hampton Harbor estuary is approximately'+4.6 feet msl while site grade is +20 feet msl; therefore the estuary will accept the surface drainage from the site.1.1 Background-The Removal of Excavation Environmental Plan will address; Storm Water Pollution Prevention Plan, Control of dust from digging and crushing of excavation, and Spill Counter Measures. The purpose is to include provisions to maximize the potential benefits of pollution prevention, sediment control measures, spill prevention, and environmental sampling at the excavation spoils removal site.The project site as well as the scope of the project was walked down and discussed with New Hampshire Department of Environmental Services (NH DES) on November 20, 2009. Senior Wetlands Inspector, Dr. Frank D. Richardson (see Attachment 7). Dr. Richardson agreed with the steps in place for phase 1 and 2 of the project to protect the wetlands. He also provided positive comments on the vendor knowledge and record working with DES Wetland Bureau permitting.

2.0 Overall

Project Phasing The project will be performed in 3 phases. The 32 acres will be divided in half with a north/south line, each half being approximately 16 acres. Phase 1 will be the Western most half and will be to remove the excavation in this area to a depth of approximately 15 feet. Phase 2 will be to do the same to the second half of the 32 acres. These phases will trade back and forth until we are at or near our preconstruction ground level.Phase 3 of the project is for the contouring and reseeding of the land to return to its' natural state; pre-.construction. This project will require aformal reclamation plan that will be developed in the future as the initial phases are estimated to be > 3 years in duration.3.0 Environmental

3.1 Control

of Storm Water Purpose of our control of storm, water run-off is to prevent storm water pollution to the marsh area.During the dumping of the excavation materials in this location a 25 foot high berm was built on the* south easterly end of the acreage separating the excavation material from the wetlands.During the first two phases of this project we will not excavate within 100 feet of the toe of this berm.This will prevent runoff from affecting the wetlands. During phase three the formal reclamation plan Will include silt fencing and other measures to protect the wetlands from potential run-off.5 Environmental Reclamation of 32 Acres behind General Office Building 3.2 Control of Dust from crushing stone and movement of the excavation materials Water will be used to keep dust down to a controllable level. The water will be sprayed over the work area as a fine mist. The water will come from a water truck kept at the site.No ground water withdrawals will be made for any purpose as part of this project: 3.3 Control of Noise The excavation of the spoils and the use of a rock crusher will produce a significant amount of construction noise. In consideration of our neighbors that abut our property we will control the hours of operation for this work site. Excavation and rock crushing will take place between the hours of 0630 to 1600 (6:30AM to 4:00 PM)'Monday through Friday.3.4 Spill Counter Measures The purpose is to prevent spills of fuels and other man-made products to this area and to mitigate the impact of any spill that should occur.3.4.1 Prevention Only plant approved expendable products will be used in this area. Anytime the site is not in use these materials will be locked in a Combustible storage container at the site.Any tanks for fueling of vehicles and machinery at the site will be Above Ground EPA Certified Self-Contained Tanks. This means at a minimum they will be double walled and located in a concrete vat. The vendor will be responsible for periodic inspection of concrete vat to ensure integrity and that rain water is not affecting its ability to contain fuel if a spill should occur.3.4.2 Mitigation A spill kit will be kept at the site and in good repair in the event of a spill. All spills will be reported to the Maintenance Services Department who will make the proper site notifications.

3.5 Sampling

The excavation material primarily comes from two sources; tunnel excavation spoils and, to a smaller amount, from the dry fuel storage excavation. Neither area has a history of oil or chemical contamination (ref Attachment 4). In 2001 during the sale of the station to FPL an Environmental Assessment was performed by consultant Hailey &Aldrich. In the Phase 1 Environmental Site Assessment Report, Hailey & Aldrich stated there'was no significant environmental concerns' with this area. Some solid waste was noted in the area and this was cleaned up' prior to the closing as a sale condition mandated by FPL (Summer 2002).Haley & Aldrich had no recommendations for further Phase II environmental. sampling in this area.Approximately 3 million tons of excavation spoils occupies these 32 acres and creates a mound approximately 25 feet high.. Phase 1 of the reclamation plan is to remove spoils to a depth of 15 feet from the westerly 16 acres. Due to the history of this area, the assessment performed by Hailey &Aldritch in 2001-2002, and the known source of the excavation spoils we will pull 16 composite samples from the Phase 1 area (see attachment 5). One sample from each acre, which will be a composite of spoils from 0 to 15 feet in depth (see attachment 3). These samples will be analyzed for: Resource Conservation and Recovery Act (RCRA) metals, Polychlorinated biphenyls (PCBs), Extractable petroleum hydrocarbons (EPH) with polycyclic aromatic hydrocarbons (PAW) and Volatile petroleum hydrocarbons (VPH) (see attached). The specifics of sampling, cost and responsibilities is contained.in Attachment 2 'Golder Associates Re: Request for Proposal' and Attachment 3 'Sample Tracking of Excavation Spoils Form'6 Environmental Reclamation of 32 Acres behind General Office Building Sampling requirements for Phase 2 of this project will be determined with the Seabrook Licensing Group and Juno Environmental Services of the Business Strategy and Policy Group based on the results of Phase 1 sampling.If at anytime time during the project unexpected materials are unearthed the project will be halted.Maintenance Services will be contacted and appropriate measures will be taken to determine if environmental or personnel hazards are present.4.0 Protection of Potential Archeological Sensitive Areas Along the edges of the toe of the berm are potential archeological sensitive areas (see Attachment 8).These areas have been walked down with the contractor performing the excavation work and the Maintenance Services Department. No work will be performed in these areas during Phase 1 and 2 (removal of excavation spoils from a distance of 100 feet from toe of berm). At the time when the berm is removed there will be a more formal reclamation plan and specifics for protection of these important sites will be laid out in detail.5.0 Oversight Maintenance Services will conduct periodic walk downs/observations of the site to ensure compliance with this plan and station standards. The walk downs will be on a weekly basis. If the environmental control measuresare ineffective the plan will be amended and any changes implemented within 7 calendar days of the inspection. Pictures should be taken occasionally during these walk downs to maintain a visual record of the project Inspection frequencies can be reduced to monthly if the jobsite is stabilized or runoff is unlikely due to winter conditions or seasonally arid conditions. These walk downs and observations will be documented on human performance walk down forms for retention. 7 Environmental Reclamation of 32 Acres behind General Office Building Attachment 1 List of Individuals Who Have Reviewed this Document either in whole or Part Mitchell S.

Subject:

, RE: Reclamation project at Seabrook Station All, The environmental conditions at the South 40 Tunnel Muck Disposal Area were reviewed by our consultant Haley& Aldrich in the Phase I Environmental. Site Assessment performed in support.of the sale (March 200 1). There were no significant environmental concerns noted in the South 40 area which functioned as the disposal area for bedrock spoils (ref: p. 43 of report). Haley & Aldrich observed some solid waste disposed in the area however,.subsequently there was an extensive cleanup (Seabrook Trucking) of the South 40 and other areas just prior to the closing (Summer 2002) as a sale condition mandated by FPL. Haley & Aldrich did not identify anything in the South 40 as a "Recognized Environmental Concern" (ref pp 46 -49 of report for RECs) nor were there any recommendations for further Phase II environmental sampling in thatarea.Also, the majority of the bedrock in the South 40 area was removed well before the Haley-& Aldrich investigations in the early 1990s by a contractor for road construction work. I do not recollect any environmental sampling being done in conjunction with that contract or any issues arising during the course of rock removal or thereafter. The excavated soil from the dry fuel storage area in 2007/2008 and now deposited in the South 40 area also pose little or no environmental risk. The area where the soils were excavated did not have any history, of oil or chemical contamination and there are no. concerns stated for this area in the Haley & Aldrich report. See p. 34 for a discussion of the Carpentry Shop and Mixed Solid Waste Area.I think we have a good documented basis for concluding that the environmental conditions in the South 40 disposal area are satisfactory and there is little risk of oil or chemical contamination in the remaining tunnel rock or stockpiled soils. If any environmental sampling is done in this area I would recommend that it take into consideration the low risk of contaminated rock or soil in the area.Al Legendre.Principal Engineer NextEra Energy Seabrook, LLC 603 773-7773 13 Environmental Reclamation of 32 Acres behind General Office Building Attachment 5 14 Environmental Reclamation of 32 Acres behind General Office Building Attachment 6, E-mail from NUDES Senior Inspector regarding the Project and Environmental Plan Hello Dan, I conducted a field inspection of the proposed 32 acre reclamation site at Seabrook Station on November 20, 2009 with Arleigh Greene and Rusty Lavin of the Seabrook Truck Center.The primary concern at this location is the protection of the nearby tidal wetlands and the maintenance of a minimum of a 100 foot tidal buffer zone in natural, undisturbed vegetation adjacent to the salt marsh.* The berms that are present on site will help accomplish the separation of construction activities associated With the materials removal and the-salt marsh needed to assure that the ecological integrity of the tidal wetlands and buffer zone are preserved. In a recent email, Arleigh Greene has assured me that: "No excavation will take place within 100 feet of the easterly and southerly toe of the berms" All storm water runoff must be detained and treated before leaving the site in the direction of the adjacent tidal wetlands. The NH DES Alteration of Terrain program would be the agency charged with the review and approval of- final site plans for storm water controls.Arleigh Greene and Rusty Lavin are both familiar with DES Wetlands Bureau permitting requirements and protocol from previous projects they have been involved With., There is no Wetlands Permit required for the work proposed at this site given the provisions cited above.t Yours truly, (Frank Frank D.

Box 300 Seabrook, New Hampshire 03874-0300 RE: SOIL SAMPLING AND ANALYSIS REPORT SEABROOK STATION SEABROOK, NEW HAMPSHIRE

Dear Mr. Kelsey:

Golder Associates Inc. (Golder) is pleased to present this Soil Sampling and Analysis Report for activities conducted at Florida Power and Light's (FPL) site in Seabrook, New Hampshire (Seabrook Station, Site).Figure 1 shows the Site and general vicinity. This report presents Golder's findings from soil sampling activities conducted between March 31, 2010 and April 2, 2010 and presents the results of the analytical testing.BACKGROUND During construction of the Seabrook Nuclear Power Plant in the 1970s, two sub-ocean water-cooling tunnels were constructed. Golder understands that approximately three million tons of the material generated during the tunneling was placed over approximately 32 acres of land at the Site. FPL plans to reclaim the original ground surface, and; in doing so, excavate and sell the land-applied materials for reuse. Golder understands that the material will be excavated in two phases of approximately 16 acres each and sold to a vendor for reuse in the New England area as fill and road base. Golder observed the excavation of 16 test trenches at the Site (see Figure 2) and collected samples of soil (approximately one sample per acre) from each trench for chemical analysis.FIELD ACTIVITIES Golder observed the excavation of 16 test trenches at locations designated by Mr. Mark Leavitt of FPL.The test trenches were excavated to a depth between approximately 7.5 and 15 feet below ground surface (ft bgs) by an FPL-supplied operator. Golder visually observed the soil and screened samples using a photoionization detector (PID) with a 10.6 eV lamp calibrated to a 100 parts per million (ppm)isobutylene reference gas prior to sample collection. Golder collected one composite sample per trench and submitted the samples to Eastern Analytical Inc. (EAI) of Concord, New Hampshire for the following analyses: 1 Resource Conservation and Recovery Act (RCRA)-8 metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) via EPA Method 200/7000 series ED Polychlorinated biphenyls (PCBs) via EPA Method 8082 0 Extractable petroleum hydrocarbons (EPH) with polycyclic aromatic hydrocarbons (PAH)via the Massachusetts (MA) EPH Method Golder also collected one discrete (i.e. non-composited) sample per trench and submitted the samples to EAI for volatile petroleum hydrocarbons (VPH) analysis via the Massachusetts VPH method. The VPH analytical method does not allow compositing of samples. The suite of analyses was selected for screening purposes andwas not intended to be an exhaustive list of analyses or compounds. p:\proijcts\2010\103-87221 seabrook otaton\report~naltsoil sampinr report 4-2010.docx Golder Associates Inc.670 N.

No PCB, VPH, or EPH compounds (except for EPH C19-C36 aliphatic hydrocarbons) were detected at a concentration above the laboratory reporting limit. Therefore, analytical results for these compounds are not presented in Table 1. The laboratory analytical reports, which provide all analytical results, are provided in Appendix A. EAI detected the following analytes in the soil samples at concentrations above the laboratory reporting limit: 0l Arsenic, barium, chromium, and lead in all of the samples El Silver in sample TT-C4 19 C19-C36 aliphatic hydrocarbons in samples TT-C9 and TT-C14 For comparison purposes, typical New Hampshire and Massachusetts soil regulatory standards are provided in Table 1. Detected parameter concentrations that exceed one or more of the comparative regulatory standards are highlighted in bold in Table 1. As noted previously, these analytical results and comparative state standards are provided for screening purposes only. The location and end use of the materials will determine, which, if any, regulatory standards may apply.CLOSING The results presented in this report are based upon analytical data collected as described in the report.Golder does not and cannot represent that the site contains no hazardous material, oil, or other condition beyond that observed by Golder during its activities. This report does not reflect: 1) undetected variations in soil characteristics or chemical concentrations which may occur between the sampling locations;, or 2)the potential presence of chemical compounds or analytes which were not analyzed for, or which may be present below the minimum reportable concentrations for the methods used.The information contained in this report may not be suitable for any further use without adaptation for the specific purpose intended.

.(WHITE: ORIGINAL GREEN: PROJECT MANAGER).:.9 Page 1 of 70 Health Physics Study I Technical Information Document (HPSTID)Cover Page Number: HPSTID-10-003 Title: Assessment of Soil Removal from Rock Pile Area South of General Office Building (Phase One)Comments: (:: 14. a/ýýOriginator: Independent Reviewer:__.Date: 4__o Date:_______ Date:_________ 1M11'6Uz1-- Approver: HP Oeo(rtmeint lupervisor HPSTID-10-003 Page 2 of 70 OBJECTIVE To document the radio!ogical assessment of soil to be removed from the Rock Pile Area located south of the General Office Building (GOB).BACKGROUND During the construction of Seabrook Station the 32 acres of land located south of the GOB was used to relocate fill removed from various areas on site, primarily from -the excavation of the intake and discharge.tunnels. Since Station construction, fill removed from the excavation of the Dry Fuel Storage site has also been relocated to this area south of the GOB.In an effort to return the area south of the GOB to its original condition, the excavation spoils located there are to be removed and sold to a vendor for reuse in the New England area as fill and road base. The fill will be removed from site in two phases. In Phase 1, fill will be removed from the western half of the Rock Pile Area and in Phase 2 removal will be from the eastern half of the Rock Pile Area (see Attachment 1).This HPSTID documents the radiological assessment of the bulk soils to be removed from site in Phase 1 of the project, as required by the Station Radiation Protection Manual (SSRP) procedure RP.13.1, Radiological Controls for Material[1]. Additionally, the Radiation Protection department will be notified by the project prior to commencement of Phase 2 of soil removal in order to determine if additional assessment of materials is desired.ASSESSMENT Samples of soil were taken from various locations on 8/25/2009 and 3/8/2010.Table 1 lists the locations by GPS coordinates for samples taken.Table 1 Soil Sample GPS Coordinates Sample Date UTM GPS Coordinates Radiological Survey No.8/25/2009 19T 0348395 / 4750382 M-20090825-3 8/25/2009" 19T 0348409 / 4750449 M-20090825-3 3/8/2010 19T 0348467 /4750288 M-20100311-7 3/8/2010 19T 0348440 / 4750381 M-20100311-7 3/8/2010 19T 0348444 / 4750434 M-20100311-7 .3/8/2010 19T 0348348 / 4750414 M-20100311-7 3/8/2010 19T 0348372 / 4750342 M'-20100311-7 3/8/2010 19T 0348401./4750309 M-20100311-7 The isotopic content of the four-liter soil samples obtained were evaluated using routine count roorh analysis techniques found in procedure HD0958.32, Release (\ HPSTID-10-003 Page 3 of 70 of Material from Radiological Controls[2]. Counting parameters established in reference [2] for four-liter samples meet the environmental LLDs for sediment as per the Seabrook Station Offsite Dose Calculation Manual[3]. Results of isotopic analyses indicate no presence of radioactive material other than natural background radioactivity. Attachment 2 contains the results of isotopic analyses performed. Though no cesium -137 (Cs-137) was detected in soil samples taken, soil samples taken in the past from areas around site have had indications of trace quantities of Cs-1 37, attributable to man-made radioactive fallout from atmospheric weapons testing. This study is documented in HPSTID 00-007, Cesium-137 in Site Soil Samples [4].In addition, radiation surveys were performed on 8/25/09, 3/9/10 and 3/10/10 at the Rock Pile Area with a Ludlum Model 19 Micro R survey meter. Results of radiation surveys performed indicate no activity above background. Attachment 3 contains the results of radiation surveys performed. CONCLUSION A review of samples and surveys taken indicate no presence of radioactive material other than natural background radioactivity and in conjunction with Seabrook Station Radiation Protection (SSRP) Manual procedure RP13.1, Radiological Controls for Material, it is reasonable and a business case exists to remove material from the Rock Pile Area designated as Phase 1 in an effort to reclaim the land.REFERENCES

I appreciate your assistance with this item. Please feel free to contact Mike O'Keefe at (603) 773-7745 should you have any questions or need additional information related to this matter.Sincerely, Paul Freeman Site Vice President Attachments NextEra Energy Seabrook, LLC Temporary Use Agreement Attachment

1. Description and Need 1) a description of your intended use of the railroad land, the length of time that the work will take and an explanation of the need for the crossing at the location identified. (e.g.construction access)The railroad land will be used to provide an access road. It is estimated that this access road will be in place for three to five years. The crossing will provide access to remove excavation' material from approximately 32 acres on the south easterly portion of the NextEra property and facilitate the environmental reclamation of this property.

-Currently the only access is through the South Access Road Security Gate which was constructed as a result of NHDOT Bureau of Rail and Transit approval dated February 22, 2002 to North Atlantic Energy"Seabrook Station Corridor Crossing Agreement." This agreement was assigned to NextEra in November 2002.This alternate crossing will alleviate unnecessary traffic coming through the only security checkpoint for the power plant that, operates full time, providing a relief of an unnecessary burden on security and site personnel. In addition, the access road will improve traffic flow and safety during the project to site personnel. NextEra understands that NHDOT prefers a Temporary Use Agreement which is valid for a one year term should be utilized for this access road. Each year, NextEra will be required to renew the Temporary Use Agreement. As previously noted, it is anticipated that this access road will be in place for three to five years. .2) a photograph, a location map and a plan or sketch of the area showing the property lines and the area of the railroad corridor to be entered onto.Attachment 2 provides photographs and the location map.3) documentation of your ownership (i.e. deed and/or assessor's card) of your property adjacent to the State-owned railroad property, if applicable. Attachment 3 provides the NextEra deed for the property. Please note NextEra Energy Seabrook, LLC was formerly named FPL Energy Seabrook, LLC.

The project plan and environment plan have been reviewed in whole or in part by representatives of the Legal, Environmental, Budget and Radiation Protection Departments from Seabrook and our corporate offices (see attachment 1).Summary During the construction of Seabrook Station and a few projects since (i.e. Dry Fuel Storage), excavation spoils have been stock piled on the 32 acres behind the General Office Building (GOB). This, approximately 3 million tons of excavation, has disturbed the land from its original and natural environment.

The fill is comprised of soils, different sized bedrock spoils, and boulders to large to crush and a minor amount of construction spoils of varying types (i.e. asphalt, concrete, etc...).The effort to reclaim this land will be a 3 phase project. The 32 acres will be split in half by a north/south line. The first phase is to remove the fill to approximately a 15 foot depth on the westerly 16 acres.Phase 2 will be to remove fill to a depth of approximately 15 feet on the easterly 16 acres. This process will continue until the area is returned to its original elevation. Phase 3 would be to add topsoil, grade and contour the area, and establish natural flora to the area by seeding and planting as required.This paper is to discuss the first and second phases of the project. The third phase will require a formal reclamation plan and would not be started until at least 2013.Radiological Considerations The Radiological Protection (RP) Department has taken several soil samples from the area identified as Phase 1 and analyzed these samples for radioactivity. In addition, direct survey measurements were taken at the site where Phase 1 of excavation removal will occur. The results will be documented in Health Physics Study/Technical Information Document (HPISTID) 10-003, Assessment of Soil Removal from Rock Pile Area South of General Office Building (Phase One).A review of these samples and surveys indicates no presence of radioactive material other than natural background radioactivity and in conjunction with'Seabrook Station Radiation Protection (SSRP) Manual procedure RP13.1, Radiological Controls for Material, it is reasonable and a business case exists to remove this material in an effort to reclaim the land.Once the project commences the RP department shall be notified of any new materials, that are brought into theproject area that could potentially be removed from site. Additionally, RP shall be notified prior to the commencement of Phase 2 of excavation spoil removal.Security Increased and steady truck traffic at the south gate and in and out of the GOB parking lot presents a number of safety concerns. Some of these safety concerns include increased opportunities for falling debris to hit someone and debris falling onto the road way and/or the GOB parking lot entrance causing pedestrian and traffic hazards.2 Environmental Reclamation of the 32 Acres behind the General Office Building In an effort to have this increased traffic avoid the south gate and the GOB parking lot altogether, Security suggests the vehicles enter the fill site via F lot. The trucks would drive up the south access road, turn right onto the Hannah Foods road and left into F lot. A second, active gate will be installed at the rear of F lot allowing the trucks to access the fill area. The trucks would then. leave the fill area the same way they entered, through F lot.By utilizing this traffic pattern the trucks will avoid all contact with the south gate and the GOB parking lot thus eliminating many of the safety concerns for site employees andtheir vehicles. At the end of the work day the driver of the last truck leaving will be required to close and lock both F-lot gates thus closing off the fill area from public access.Prerequisites to use the F lot for access: 1) Construction of active gate at the rear of F lot to facilitate access to the pit area.2) Locks installed on the gates. (Keyed or combination locks are acceptable with the necessary access provided to security).

3) Installation of appropriate number ofjersey barriers placed at the back of the dirt road connecting the pit area and the GOB parking lot. These barriers will block access at the pit side of the dirt road and not allow anyone to drive down the dirt road toward the GOB parking lot.4) Instructions and expectations to vendor requiring the gates be opened and closed and locked as appropriate.

Licensing/Environmental See the Environmental Plan for the Removal of Excavation Material Stock Piled on 32 Acres behind the General Office Building during Construction of the Site attached to the end of this document.Financial Contract for this project is 02218558.The contract with Seabrook Trucking Center calls for $1.35 per cubic yard.The contract ends on August 17, 2012.Seabrook Truck is responsible for all taxes on the removal of gravel and permits required for this project.Cost for environmental sampling will be shared by Nextera Energy-Seabrook and Seabrook Truck Profit realized by Nextera Energy-Seabrook will be shared accordingly with Joint Owners Legal The contract agreement between Nextera Energy-Seabrook and Seabrook Truck has been reviewed by General Counsel Legal and found to be satisfactory. A review of zoning in the area of the project has been reviewed and found to have no issues (see attachment 6).General Counsel deferred to on the Juno Environmental Services (YES) part of the Business Strategy and Policy Group for review and approval of the Environmental Sampling Plan'. JES has reviewed the contract from Golder Associates (Attachment

2) for sampling and found it to be satisfactory.

3 Environmental Plan For the Removal of Excavation Material Stock Piled on 32 Acres behind the General Office Building during Construction of the Site March 23, 2010 Rev-I Environmental Reclamation of the 32 Acres behind the General Office Building 1.0 Introduction During construction of Seabrook Station (SBK) excavation spoils was stock piled on the 32 Acres behind the General Office Building (see attachment 5). There are approximately 3 million tons of fill in this area..At some point in the life span of SBK this area would need to be reclaimed and returned to its natural state as it existed prior to the erection of this facility.The SBK site is bordered on the east by an extensive salt marsh and is located on a point called "The Rocks" between two small tidal estuaries, the Brown'sRiver'and the Hunt's Island Creek. Adjoining the site is a broad, flat marsh zone in the north east and south identified as Hampton Flats with an elevation of approximately +4 feet mean sea level (msl). The normal high tide water level at Hampton Harbor estuary is approximately +4.6 feet msl while site grade is +20 feet msl; therefore the estuary will accept the surface drainage from the site.1.1 Background The Removal of Excavation Environmental Plan will address; Storm Water Pollution Prevention Plan, Control of dust from digging and crushing of excavation, and Spill Counter Measures. The purpose is to include provisions to maximize the potential benefits of pollution prevention, sediment control measures, spill prevention, and environmental sampling at the excavation spoils removal site.2.0 Overall Project Phasing The project will be performed in 3 phases. The 32 acres will be divided in half with a north/south line, each half being approximately 16 acres. Phase 1 will be the Western most half and will be to remove the excavation in this area to a depth of approximately 15 feet. Phase 2 will be to do the same to the second half of the 32 acres. These phases will trade back and forth until we are at or near our preconstruction ground level.Phase 3 of the project is for the contouring and reseeding of the land to return to its' natural state;pre-construction. This project will require a formal reclamation plan that will be developed in the future as the initial phases are estimated to be > 3 years in duration.3.0 Environmental

3.1 Control

of Storm Water Purpose of our control of storm water run-off is to prevent storm water pollution to the marsh area.During the dumping of the excavation materials in this location a 25 foot high berm was built on the south easterly end of the acreage separating the excavation material from the wetlands.During the first two phases of this project we will not excavate within 100 feet of the toe of this berm. This will prevent runoff from affecting the wetlands. During phase three the formal reclamation plan Will include silt fencing and other measures to protect the wetlands from potential run-off.5 Environmental Reclamation of the 32 Acres behind the General Office Building 3.2 Control of Dust from crushing stone and movement of the excavation materials Water will be used to keep dust down to a controllable level. The water will be sprayed over the work area as a fine mist. The water will come from a water truck kept at the site.No ground water withdrawals will be made for any purpose as part of this project.3.3 Spill Counter Measures The purpose is to prevent spills of fuels and other man-made products to this area and to mitigate the impact of any spill that should occur.3.3.1 Prevention Only plant approved expendable products will be used in this area. Anytime the site is not in use these, materials will be locked in a Combustible storage container at the site.Any tanks for fueling of vehicles and machinery at the site will be Above Ground EPA Certified Self-Contained Tanks. This means at a minimum they will be double walled and located in a concrete vat. The vendor will be responsible for periodic inspection of concrete vat to ensure integrity and that rain water is not affecting its ability to contain fuel if a spill should occur.3.3.2 Mitigation A spill kit will be kept at the site and in good repair in the event of a spill. All spills will be reported to the Maintenance Services Department who will make the proper site notifications.

3.4 Sampling

The excavation material primarily comes from two sources; tunnel excavation spoils and, to a smaller amount, from the dry fuel storage excavation. Neither area has a history of oil or chemical contamination (ref Attachment 4). In 2001 during the sale of the station to FPL an Environmental Assessment was performed by consultant Hailey& Aldrich. In the Phase 1 Environmental Site Assessment Report, Hailey & Aldrich stated there'was no significant environmental concerns' with this area. Some solid waste was noted in the area and this was cleaned up prior to the closing as a sale condition mandated by FPL (Summer 2002). Haley & Aldrich had no recommendations for further Phase II environmental sampling in this area.Approximately 3 million tons of excavation spoils occupies these 32 acres and creates a mound approximately 25 feet high. Phase 1 of the reclamation plan is to remove spoils to a depth of 15 feet from the westerly 16 acres. Due to the history of this area, the assessment performed by.Hailey & Aldritch in 2001-2002, and the known source of the excavation spoils we will pull 16 composite samples from the Phase 1 area (see attachment 5). One sample from each acre, which will be a composite of spoils from 0 to 15 feet in depth (see attachment 3). These samples will be analyzed for: Resource Conservation and Recovery Act (RCRA) metals, Polychlorinated biphenyls (PCBs), Extractable petroleum hydrocarbons (EPH) with polycyclic aromatic hydrocarbons (PAH)and Volatile petroleum hydrocarbons (VPH).6 Environmental Reclamation of the 32 Acres behind the General Office Building The specifics of sampling, cost and responsibilities is contained in Attachment 2 'Golder Associates Re: Request for Proposal' and Attachment 3 'Sample Tracking of Excavation Spoils Form'Sampling requirements for Phase 2 of this project will be determined with the Seabrook Licensing Group and Juno Environmental Services of the Business Strategy and Policy Group based on theresults of Phase 1 sampling.4.0 Protection of Potential Archeological Sensitive Areas Along the edges of the toe of the berm are potential archeological se-n-itive areas (see attachment 7).These areas have been walked down with the contractor performing the excavation work and the Maintenance Services Department. No work will be performed in these areas during Phase 1 and 2 (removal of excavation spoils from a distance of 100 feet from toe of berm). At the time when the berm is removed there will be a more formal reclamation plan and specifics for protection of these important sites will be laid out in detail.5.0 Oversight Maintenance Services will conduct periodic walk downs/observations of the site to ensure compliance with this plan and station standards. The walk downs will be on a weekly basis. If the environmental control measures are ineffective the plan will be amended and any changes implemented within 7 calendar days of the inspection. Pictures should be taken occasionally during these walk downs to maintain a visual record of the project Inspection frequencies can be reduced to monthly if the j obsite is stabilized or runoff is unlikely due to winter conditions or seasonally arid conditions. These walk downs and observations will be documented on human performance walk down forms for retention.

Box 300 Sesbrook, New Hampshire 03874-0300 RE: REQUEST FOR PROPOSAL SEABROOK STATION SEABROOK, NEW HAMPSHIRE Dear Mr. Kelsey.Golder Associates Inc. (Golder) Is providing this proposal for professional services at. Florida Power and Ught's (FPL) site In Seabrook, New Hampshire (Seabrook Station, Site). FPL requested a proposal for assistance with sampling and analysis of land-applied materials at Seabrook Station from historic sub-oceanic tunneling activites. BACKGROUND Golder understands that approximately three million tons of material generated during sub-oceanic tunneling was placed over approximately 32 acres of land at Seabrook Station. FPL would Ike to reclaim the original ground surface, and, In doing so, excavate and sell the land-applied materials for reuse. Golder understands that the material will be excavated In two phases.of approximately 16 acres each and sold to a vendor for reuse In the New England area as fill nd road base. FPL has requested a proposal from Golder to collect and chemically analyze samples of the material prior to excavation and sale. FPL Intends to collect 16 samples (approximately one sample per acre) during the first phase of the excavation. The number of samples collected for the second phase of excavation will be based on the results of the rWt phase of sampling.SCOPE OF SERVICES Based upon our discussions with FPL, we understand the scope of services to Include the activities summarized below which we have broken down Into two tasks: Task 1: Coordination and Samoilno Golder will observe the excavation of 18 test trenches to approximately 15 feet by an operator supplied by FPL and collect one composite sample per trench. Golder will observe the soil visually and screen the samples using a photoionIzation detector (PID) prior to sample collection. Golderwill submit the samples to Eastern Analytical Inc. (E) of Concord. New Hampshire for analysis. At a minimum, Golder recommends the following analyses: N Resource Conservation and Recovery Act (RCRA)-8 metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) via EPA Method 20017000 series 0 Polychlorlnated biphenyls (PCBs) via EPA Method 8082 E Extractable petroleum hydrocarbons (EPH) with polycyclic aromatic hydrocarbons (PAH) via the Massachusetts EPH Method Golder Assaclates bic.570 N. cWMuMWa 3L.

RE: Reclamation project at Seabrook Station All, The environmental conditions at the South 40 Tunnel. Muck Disposal Area were reviewed by our consultant Haley& Aldrich in the Phase I Environmental Site Assessment performed in support of the sale (March 2001). There were no significant environmental concerns noted in the South 40 area which functioned as the disposal area for bedrock spoils (ref. p. 43 of report). Haley & Aldrich observed some solid waste disposed in the'area however subsequently there was an extensive cleanup (Seabrook Trucking) of the South 40 and other areas just prior to the closing (Summer 2002) as a sale condition mandated by FPL. Haley & Aldrich didnot identify anything in the South 40 as a "Recognized Environmental Concern" (ref pp 46 -49 of report for RECs) nor were there any recommendations for further Phase II environmental sampling in that area.Also, the majority of the bedrock in the South 40 area was removed well before the Haley & Aldrich investigations in the early 1990s by a contractor for road construction work. I do not recollect any environmental sampling being done in conjunction with that contract or any issues arising during the course of rock removal or thereafter. The excavated soil from the dry fuel storage area in 2007/2008 and now deposited in the South 40 area also pose little or no environmental risk. The area where the soils were excavated did not have any history of oil or chemical contamination and there are no concerns stated for this area in the Haley &.Aldrich report. See p. 34 for a discussion of the Carpentry Shop and Mixed Solid Waste Area.I think we have a good documented basis for concluding that the environmental conditions in the South 40 disposal area are satisfactory and there is little risk of oil or chemical contamination in the remaining tunnel rock or stockpiled soils. If any environmental sampling is done in this area I would recommend that it take into consideration the low risk of contaminated rock or soil in the area.Al Legendre Principal Engineer NextEra Energy Seabrook, LLC 603 773-7773 13 Environmental Reclamation of the 32 Acres behind the General Office Building Y% ýjd ýniVfe 5 Q@(Attachment 5 of Project and Propose(i~;-H/ -V;F,)-7)5-. 10 7-IL;'16 14 Environmental Reclamation of the 32 Acres behind the General Office Building Attachment 6 Letter from the Town of Seabrook Regarding Zoning TOWN OF SEABROOK CODE ENFORCEMENT OFFICE 99 LAFAYETTE ROAD PO BOX 456 SEABROOK, NH 03874-0456 (603) 474-3871 code(,seabrooknh.orq March 24, 2010 Florida Light and Power PO Box 300 Seabrook, NH 03874-0300 CIO: Dan Kelsey Hard Rock Development, LLC PO Box 2750 Seabrook, NH 03874-2750 RE: Zoning Compliance, Property ID: 1111 & 2 To Whom It May Concern: The above referenced property located in Zone 3, Industrial, has no known zoning or building code violations, and is presently in full compliance with all issues with respect to the Town of Seabrook.FLP/Nextera Energy currently holds a valid Notice of Intent To Excavate for the above referenced property; said Intent was approved on December 16, 2009 by the Board of Selectmen, during their public hearing.:(If you have any questions regarding this property please do not hesitate in contacting me.Respectfully, Paul Town of Seabrook Code Enforcement Officer ogarande.seabrooknh.ora 15 Environmental Reclamation of the 32 Acres behind the General Office Building Attachment 7 Map of Potential Figure 5-K -Amhaeological Site Potential PROPERTY SURVEY SEABROOK NUCLEAR POWER STATION SEABROOK, HAMPTON FALLS & H.MPTON.

1.0 INTRODUCTION

Radiation Safety and Control Services (RSCS) has prepared this Site Conceptual Model (SCM) report to identify and characterize ground water flow and tritium distribution at, the NEXTera Energy Seabrook Station facility (Site). The development of the SCM is consistent with the Nuclear Energy Institute (NEI) Industry Ground Water Protection Initiative. The Ground Water Protection Initiative identifies actions to improve utilities'.management and response to instances where the inadvertent release of radioactive substances may result in low but detectible levels of plant-related materials in subsurface soils and water.A preliminary SCM was developed for the Site in September 2008 (RSCS, 2008). At that time no synoptic ground water elevation measurements had been completed for ground water at the Site, and no long-term monitoring of water levels had been completed at selected monitoring wells. The preliminary SCM report recommended that these ground water measurements be completed to support SCM for the Site.The specific objectives of this SCM are the following: Characterize the geologic and hydrogeologic conditions at the Site;* Evaluate the ground water elevation data collected at the Site;* Evaluate ground water quality at the Site including the vertical and horizontal extent, quantity, concentrations, and potential source(s) of tritium in ground water; and* Define'the probable source(s) of tritium at the Site.2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 5 of 51_2.0 STATION DESCRIPTION The following section presents a general summary of the Site location, a summary of surrounding land use and ground water use, and an overview of site-specific topography, surface water features, geology, hydrogeology, and ground water flow conditions.

2.1 STATION

LOCATION The Site is located in the northern part of Seabrook, New Hampshire, approximately one mile from the western shore of Hampton Harbor (Figure 1). Hampton Harbor is situated at the confluence of the Hampton, Browns, and Blackwater Rivers, and is located on the coast of New Hampshire, about 1.5 miles north of the Massachusetts state line and 13 miles south of Portsmouth Harbor. The towns of Hampton, Hampton Falls, and Seabrook abut Hampton Harbor on the north, west, and south respectively. The villages of Hampton Beach, north of the harbor entrance, and Seabrook Beach, south of the entrance, border the navigable waters of the harbor.Seabrook Station is a nuclear power plant located on a 900-acre site in the towns of Seabrook, Hampton and Hampton Falls in New Hampshire, approximately 40 miles north of Boston, Massachusetts.

2.3 SETTING

AND SURFACE WATER FEATURES The station site is situated on a point of land the terminus of which is called "The Rocks," located between the Browns River to the north, and Hunts Island Creek to the southeast (Figure 1). Adjoining the site is a broad, flat tidal marsh located to the north, east and south, identified as Hampton Flats, with an elevation of approximately +4,feet MSL. The normal high tide water level at Hampton Harbor estuary is approximately +4.6 feet MSL, while Site grade is approximately +20 feet MSL. Basled on these relationships, the natural grade and surface water flow from the plant site will be towards the tidal 'marsh. The natural drainage features of the area surrounding the site have been left unchanged, however surface water drainage within the Site is managed via a catch basin network. Some of the existing ground elevations of.the Site beyond the plant limits ind bordering on the tidal marsh are below the nominal +20 foot msl grade. These locations adjoining the tidal marsh (northeast, east, southeast and south sides) are protected by a riprap revetment or a sheetpile seawall at the edges of the embankment. 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 (I TSD#09-19 Rev 01 Page 6 of S1 2.4 AREA GROUND WATER USE Most drinking water supplies in the Seabrook area are dependent on ground water sources. Public drinking water supplies in the towns of Seabrook and Salisbury are taken from wells, which tap aquifers in ice contact deposits. These wells yield from about 300 to 700 gallons per minute (gpm), and range from 22 to 54 feet deep (Weston Geophysical Research Inc., 1969). At present, the town of Seabrook uses five wells for its public water supply, and all of these are located at least two'miles due West from the Site. Most homes, as well as commercial and industrial users in Seabrook, are supplied by the town's municipal water system (Weston Geophysical Research Inc., 1969). The town of Seabrook supplies approximately 50,000 gallons per day to Seabrook Station from the Seabrook municipal water supply system.Other wells supplying mostly domestic and farm needs are scattered throughout the area, including the towns of Hampton Falls and Kensington, which are both without public water supply systems. In the Site vicinity, a few private wells supply homes to the north of Seabrook Station, north of the Browns River. The two nearest well fields are located approximately 2,000 and 3,000 feet to the west and north of the Site, respectively (State of New Hampshire Water Resources Board, 1962).2.5 GEOLOGY The subsurface geology in the area of Seabrook Station includes up to 70 feet of unconsolidated glacial till and post-glacial marine deposits above bedrock. The bedrock in the site area includes metasedimentary quartzites, phyllites, and schists, and metavolcanic gneisses of the Merrimack Group of probable Early Paleozoic age, that are intruded by dioritic rocks of the Newburyport and Exeter plutons of possible Early to Middle Paleozoic age. Diabase dikes of Triassic/Cretaceous age locally intrude both the Newburyport and Merrimack Group Formations. (Weston Geophysical, undated).While most of the glacial deposits are comprised of till, coarser grained glacial and/or recent deposits are present to the northwest and under the tidal marshes east of the Site (Weston Geophysical, 1969). These deposits typically contain either brackish or salty water, or would be subject to salt-water intrusion under pumping conditions because of their proximity to salt water bodies.A sequence of marine and recent marsh deposits normally rests on the till along or just north of the Browns River near the northern site boundary, and also in adjoining areas to the south. West of the site, ,thin outwash deposits overlie either till or marine silts and clays. To the east, toward Hampton Beach, medium to fine sands, 50 feet or more in 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 7 of 51 thickness, occur, and are essentially saturated with salt water (Seabrook Station UFSAR).Bedrock beneath the Site includes the Newburyport Quartz Diorite and the Kittery Formation of the Merrimack Group. A large portion of the site is underlain by the Newburyport quartz diorite intrusive, a hard, durable crystalline igneous rock consisting of medium to coarse-grained quartz diorite matrix intimately enclosing inclusions of dark gray, fine-grained diorite. A portion of the southeastern area of the Site, including much of Unit 11, is underlain by the Kittery Formation metaquartzite and granulite, which occurs as a large relict inclusion welded into the enclosing Newburyport quartz diorite along a broad, transitional-intrusive contact zone. On the Site property, the bedrock surface ranges from 0 msl to +20 msl (Weston Geophysical, undated).Foliation in the Newburyport quartz diorite ranges from N70W to N7OE in strike and averages about east-west. The dip of the foliation in the quartz diorite ranges from 700 to 800 to the south (Weston Geophysical, undated). The foliation in the Kittery formation is similar with a strike of N80E and dipping 500 to the south. The most common joint orientations in the Newburyport quartz diorite strike N35-45E and N30-50W (Weston Geophysical, undated). The diabase dikes also have a strong east-northeast orientation, consistent with the orientation of the foliation and joints in the Newburyport quartz diorite and Kittery formation (Weston Geophysical, undated).Prior to plant construction, the bedrock at the Site was locally overlain by glacial lodgment till and postglacial -marine clay-silt, outwash sands, and occasional sandy beach deposits. During the construction phase at the station, all unconsolidated material was removed and replaced with up to 25 feet of engineered fill consisting of sand and gravel.Local occurrences of coarser grained glacial and/or recent deposits are evident both to the northwest and under the tidal marshes east of the Site (Weston Geophysical, 1969).These deposits typically contain either brackish or salty water, or would be subject to salt-water intrusion under pumping conditions because of their proximity to salt water bodies. On the Site property, bedrock occurs at or near the surface, becoming deeper under the tidal marshes to the south and north Where it is as much as 70 feet or more below sea level. On the site, the bedrock forms a partially buried ridge trending in an.approximately easterly direction (Weston Geophysical, undated). It is overlain by a sandy textured, but well compacted, till up to 62 feet thick. A sequence of marine and recent marsh deposits normally rests on the till along or just north of the Browns River near the northern site boundary and also in adjoining areas to the south. West of the site, thin outwash deposits overlie either till or marine silts and clays. To the east, toward Hampton Beach, medium to fine sands, 50 feet or more in thickness, occur just 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 8 of 51 below ground level on recent marsh deposits. The sands, which appear permeable, are essentially saturated with salt water (Seabrook Station U SAR).2.6 HYDROGEOLOGY The hydrogeololgy in the general vicinity of the Site consists of a surficial aquifer that occurs in glacial and post-glacial unconsolidated deposits and a bedrock aquifer. The surficial aquifer soils include beach deposits, swamp deposits and glacial drift. The glacial drift is comprised of till, ice contact, marine and outwash deposits and is up to 70 feet thick.The bedrock aquifer, which underlies the unconsolidated materials, is composed of the Newburyport quartz diorite and the metamorphosed sediments of the Merrimack group (Weston Geophysical, 1969). There is little apparent difference in the water-bearing properties of the different types of rock. Most bedrock wells yield less than 10 gpm from depths up to 300 feet (New Hampshire. Department of Resources and Economic Development, 1964).Noý major aquifers underlie the Site or are located within the adjacent area. Locally, the most productive aquifers are in the glacial outwash deposits, which are widely distributed west, and southwest of the Site (Weston Geophysical, 1969). The outwash is made up of predominantly fine, silty sand of low permeability. In the site area, it is up to 35 feet thick, and, generally, overlies marine sediments. Ground water movement in the site area is toward adjoining tidal areas located northeast, east and southeast of the Seabrook Station. Local modifications in flow direction are the result of variations in permeability of water-bearing materials and local topography. Rates of ground water movement in the Site area do not exceed 100 feet per year (Weston Geophysical Research Inc., 1969). This is based on a water table gradient of 0.06 feet per foot, as observed during high water table conditions, and a hydraulic conductivity of 104 to 105 cm/sec, Consistent with the till and bedrock, respectively.

2.7 EXISTING

WELL NETWORK A total of 19 monitoring wells have been installed at Seabrook Station. Monitoring well details including surveyed locations are presented irl Table 1, and the location of the each monitoring well is presented in Figure 2. Fifteen of the monitoring wells were installed in 2004 and the final four wells were added in 2007/2008. Monitoring wells are screened in both the surficial and bedrock aquifers, and are located to characterize both upgradient and downgradient ground water quality in each aquifer. The monitoring well network also includes several well pairs that are screened in the surficial and 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 9 of 51 bedrock aquifers. The well pairs will provide an understanding of vertical gradients across the Site.3.0 GROUND WATER FLOW AND FATE AND TRANSPORT This section describes the current understanding regarding ground water flow and tritium distribution at the Site. Previous ground water studies completed by Areva and the Seabrook Station Updated Final Safety Analysis Report (UFSAR) were reviewed to develop an understanding of ground water flow at the Site and recently collected ground water elevation data ground water were interpreted to develop ground water flow characteristics for both the surficial and bedrock aquifers. The tritium distribution at the Site was also evaluated using ground water samples collected from existing monitoring wells and on-site ground water extraction wells.3.1 DATA COLLECTION To characterize ground water flow and tritium distribution at the Site, data collected from the 19 installed wells are evaluated. Thermonitoring wells are locatedin upgradient, downgradient and biased locations, and are screened in both the surficial and bedrock aquifers. Several paired monitoring wells that are screened in both aquifers are also included in the monitoring well network. These paired monitoring wells are used to evaluate vertical hydraulic behavior between the two aquifers. A summary of the monitoring well details is included in Table 1. Since installation in 2004, the monitoring wells have been sampled on a periodic basis and ground water samples have been analyzed for tritium and general water quality parameters. A summary of tritium ground water concentrations for the 19 monitoring wells is included in Table 2.To evaluate ground water flow at the Site, synoptic ground water elevation measurements were taken in all 19 monitoring wells on April 6. 2009. These measurements were taken under "normal, ambient" site conditions while dewatering operations were in progress (see Section 3.2.6). The results of the synoptic ground water measurements are shown in Table 3. Additionally, water levels in four of the monitoring wells (SD-1, SW-1, BD-1 and BD-2) located in both the surficial and bedrock aquifers were continuously monitored from February through early April using transducers and data loggers. These measurements were used to characterize ground water flow, evaluate vertjcal groundwater movement, assess tidal influences, and evaluate ground waterremoval activity at the Site.3.2 GROUND WATER FLOW Ground water flow in the surficial and bedrock aquifers is inferred from synoptic ground water elevations measured in the 19 on-site monitoring wells. The following sections 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 10 of 51 describe ground water flow in both aquifers and vertical ground water movement between the two aquifers. The impacts of tidal variations, subsurface structures and ground water pumping activities are also discussed.

3.2.1 Surficial

Aquifer Inferred ground water contours for the surficial aquifer are shown in Figure 3. Ground water contours were developed using Golden Software SurferTM version 8.04. In, general, ground water flows in an easterly direction in the surficial aquifer discharging to the tidal mash east of the Site (Figure 3). Ground water elevations range from 17.45 feet mean sea level (msl) in the northwestern portion of the Site (SU-1).to 7.87 feet msl along the eastern side of the Site (SD-3) (Figure 3). The easterly flow direction is consistent with the presence of the adjacent tidal marsh and the presence of Browns River to the north and east.The ground water gradient is much steeper in the western portion of the Site, relative to the eastern portion of the facility where the gradient is very low (Figure 3). The significant change in gradient across the facility is most likely related to the presence of subsurface structures (see Section 3.2.5). A ground water depression is inferred near SW-3, as the ground water elevation is low in SW-3 relative to nearby monitoring wells located to the southeast (Figure 3). The low ground water elevation observed in SW-3 is related to ground water withdrawal that is occurring in the Unit 2 containment area (See Section 3.2.6). Approximately 32,000 gallons per day are pumped from Unit 2, and this significant ground water withdrawal reverses the hydraulic gradient along the southern boundary of the Site and appears to draw ground water onto the Site from the tidal marsh to the south (Figure 3).Hydrographs for SD-1 and SW-1 were developed from the long-term transducer and data logger measurements (Figures 4 and 5). Monitoring well SW-1 was logged from December 18 through April 8, 2009, while SD-1 was measured from February 5 through April 8, 2009. During the December through early February time period ground water elevations decreased in SW-1 from approximately 9 feet msl to values less than 8.5 ft msl (Figure 4). Both-wells experienced a 1 to 2-foot increase in water elevation from the early February time period through April 8, 2009 (Figures 4 and 5). These ground water.elevation variations are consistent with seasonal changes. Lower ground water elevations are typically observed in the winter months with increasing levels observed in spring related to rain and snow melt.The impact of precipitation on ground water levels in the surficial aquifer is shown in Figures 6 and 7 for SD-1 and SW-1, respectively.. Since the precipitation is most likely snow during the December through April time period, little impacts in ground water-levels are observed, even for the most significant precipitation events (Figures 6 and 7).2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 11 of 51 Similarly, much of the surface area in the eastern and southern portions of the facility is paved or part of a building footprint. Surface water is collected at the Site at numerous catch basin locations and discharged at the EPA NPDES permitted outfall 001 .The off-site discharge of surface water minimizes on-site recharge to the surficial aquifer.Superimposed on the long-term, seasonal variations in ground water elevation are numerous short-term fluctuations (Figures 4 and 5). These short-term fluctuations are not related to tidal variations or precipitation events, but are believed to be a function of ground water pumping activity (see Sections 3.2.5 and 3.2.6).3.2.2 Bedrock Aquifer Inferred ground water contours for the bedrock aquifer are shown in Figure 8, and were developed using Golden Software SurferTM version 8.04. Similar to the surficial aquifer, ground water in the bedrock also flows to the east (Figure 8). Ground water elevations range from 17.63 feet mean sea level (msl) in the northwestern portion of the Site (BU-1) to 8.90 feet msl along the southeastern side of the Site (BD-2) (Figure 8).The easterly ground water flow direction is consistent with the regional setting with Hampton Harbor and the tidal flats located to the east. The flow direction is also consistent with the structural characteristics of the bedrock. The orientation of the foliation in both the Newburyport quartz diorite and Kittery formation is generally east west, and joints in the Newburyport quartz diorite are commonly oriented to the northeast.

3.2.3 Vertical

Ground Water Migration Vertical ground water movement between the surficial and bedrock aquifers is evaluated with monitoring well pairs that are screened in each aquifer. Eight monitoring well pairs are located at the Site, and ground water elevation differences for the eight well pairs are shown in Table 4. Five of the monitoring well pairs (SD-1/BD-2, SD-2/BD-3, SU-1 1/BU-1 1, SU-1/BU-1, and SD-4/BD-5) exhibit downward migration, with three monitoring well pairs (SC-1/BD-1, SD-3/BD-4, and SU-10/BU-10) showing upward migration. Typically, downward gradients are representative of recharge areas, while upward gradients are indicative of discharge areas. Upward vertical gradients can also be related to confining layers between the aquifers, however no confining layers are present at the Site. The regional setting for Seabrook Station is consistent with a discharge area, due to the presence of the tidal flats and harbor located nearby and to the east, and upward ground water gradients would be expected. The downward gradients indicated in SU-1/BU-1 and SD-4/BD-5 are most likely indicative of recharge as these monitoring wells are located in gravel covered area where infiltration will occur.2009 Site Conceptual Model -Seabrook Station RSCS,' Inc., June 2009 TSD#09-19 Rev 01 Page 12 of 51 The downward gradient observed in SD-1/BD-2 is likely related to ground water pumping activities, as SD-1 is located within the area of influence of ongoing ground water dewatering activities (Figure 3) (see Section 3.2.6). The small downward gradients in SU-1 1/BU-1 1 and SD-2/BD-3 are potentially related to subsurface structures (see Section 3.2.4). Additional synoptic water level measurements will confirm the presence of downward gradients in these well pairs. Most of the other monitoring well pairs have upward gradients consistent with the regional setting.3.2.4 Impact of Man-Made Structures The presence of man-made structures can have a potential impact on ground water flow. At Seabrook Station these structures include concrete building foundations that were poured directly on the bedrock surface, sumps/excavations within the bedrock, and the sheetpile seawall along the northeast side of the Site. Prior to foundation/building construction, the site construction activities included a complete removal of all soils across the Site. Many of the concrete building foundations were directly sealed to the bedrock surface prior to the placement of engineered fill that now comprises the surficial aquifer at the Site. Areas of the Site with foundation walls set directly on bedrock include the Unit 1 and Unit 2 containment areas, and a large pedestal in the Turbine building that supports the turbine. These deep structures have (a rubberized membrane (EPDM) that coats the concrete and limits direct migration to the surrounding aquifer. An example of the subsurface structures in the Unit 1 containment area is shown in Figure 9. The area around Unit 1 has numerous foundations set directly on the bedrock surface and deep excavations into the bedrock beneath the containment building (Figure 9). These deep foundation structures will impede ground water flow in those areas. The flat hydraulic gradients in the Unit 1 and Turbine Building areas are consistent with the presence of subsurface impediments to ground water flow (Figure 3).The sheetpile structure on the northern side of the facility located between SU-1 0 and SU-1 1 also appears to impact ground water flow in the surficial aquifer. The ground water surface is relatively flat in the portion of the Site, as there is little ground water elevation change observed between SU-1 1 (10.04 ft msl) and SU-10 (9.9 ft msl) located along the sheetpile structure. The sheetpile wall appears to limit ground water flow and discharge to the northeast, and directs ground water discharge to the eastern end of the Site.3.2.5 Tidal Influences Tidal variations can readily affect ground water flow in near-tidal environments. Tidal variations in nearby-Hampton Harbor are significant (approximately eight feet from low to high tide), and can potentially impact ground water flow in both the surficial and bedrock aquifers. The potential tidal impacts were evaluated using the long-term water 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 13 of 51 levels collected by the transducers and data loggers. Figure 10 shows hydrographs for SD- SW, BD-1, and BD-2 for the two-day period of March 1 through March 3, 2009.Also included in the figure are tidal variations in Hampton Harbor located approximately one mile to the east. No significant tidal effects are observed in any of the four monitoring wells (Figure 10). The lack of tidal impacts is consistent with the dampening effect of the tidal marsh and the low hydraulic conductivity of the tidal marsh soils.3.2.6 Effects of Ground Water Withdrawal Ground water pumping/withdrawal activities are ongoing-at several locations at the Site.Approximately 32,000 gallons per day (gpd) of ground water is pumped from the Unit 2 containment building to control inflow of ground water. This ground water removal in Unit 2 gives rise to a ground water depression near SW-3 (Figure 3). The lack of monitoring wells on the western side of the Unit 2 containment building acts to minimize the size of the inferred ground water depression shown in Figure 3, as ground water levels on the western side of Unit 2 are most likely lower than that inferred on Figure 3.The ground water flow map also indicates that off-site ground water from the tidal marsh is potentially being drawn onto the Site in the area south of Unit 1 and 2. The elevated chloride levels detected in selected wells, along with synoptic GW level measurements suggest that marsh water is being drawn towards the plant effectively reversing GW flow in the region along the southern edge of the Site (Figure 3 and Table 5).Based on the significant pumping rate in the Unit 2 containment area the actual ground water depression near SW-3 is likely broader than that shown in Figure 3. An estimation of the ground flow contours assuming a larger area of ground water depression associated with Unit 2 is shown in Figure 11. These revised ground water contours emphasizes the reversal of ground water gradient along the southern side of the Site and the potential for ground water from the tidal marsh to be drawn onto the Seabrook Site.Ground water withdrawal activities are focused on the Unit I containment area to minimize ground water inflow to the buildings. A total of five locations regularly withdraw ground water under hydrostatic conditions in the Unit 1 area at a combined rate of approximately 3,000 gpd (Figure 9). No significant ground water depression in the surficial aquifer is observed in the Unit 1 area, however ground water also appears to flow onto the Site south of Unit 1 as a function of the Unit 1 withdrawal and/or Unit 2 pumping activity (Figure 3). Elevated levels of chloride are also present in SW-1 (640-2400 ppm) and SW-2 (480 ppm) and are consistent with mixing with the tidal marsh ground water (Table 5).Review of the hydrographs for SD-1, SW-1, BD-1, and BD-2 does indicate the presence of small, abrupt variations in water levels that are observed in several of the monitoring wells at the same point in time (Figure 12). These perturbations appear to be consistent 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 14 of 51 with the cycling of a pump or pumps that are removing ground water. At any given time ground water withdrawal may be ongoing at up to five site locations and it is hard to determine which dewatering system is operating "periodically" at any given time.3.3 TRITIUM. DISTRIBUTION IN GROUND WATER In September 1999, elevated tritium concentrations were identified in ground water that was seeping into the containment annulus. This was interpreted to indicate that tritium-contaminated ground water from an unspecified location was leaking from that location into the containment annulus. Seabrook Station personnel evaluated the leak and determined that the Cask Loading Area/Transfer canal adjacent to the Spent Fuel Pool was leaking approximately

0.1 gallons

per day (gpd) into the Spent Fuel Pool tell tale drain collection lines. This flow rate increased to 30 to 40 gpd after the leak off collection lines were hydrolazed. The Spent Fuel Pool leakage contaminated the surrounding concrete of the structure which resulted in diffusion of tritium contamination into ground water beneath and adjacent to the fuel building. This leak was not directly to ground water, but to the interstitial space between the stainless steel fuel pool liner and the concrete building foundation. The water that leaked into this space was initially at the same concentration as the fuel pool water. As part of the mitigation of this leak the interstitial space was drained and the leak in the stainless steel liner was. repaired.This tritium contamination is the only significant tritium release that has impacted ground water at the Site, and appropriate corrective actions were initiated to minimize and terminate the release. In addition to leak repair activities, the corrective actions include regular withdrawal of ground water in the area around the fuel building, PAB and containment. These activities included the use of dewatering systems already in place to mitigate ground water leakage into lower levels of site structures. Additionally, Unit 2 water withdrawal was maintained to dewater the structure. Another important part of the corrective actions was the initiation of a monitoring well network at the Site.Consistent with the corrective action for the tritium release, five dewatering locations have been established in the fuel building, PAB and containment area of Unit 1 and include (Figure 9): o A dewatering pump in the containment enclosure area (CEVA) located at -31 ft msl, A dewatering well located in the Primary Auxiliary Building_(PAB) adjacent to the fuel pool that cycles ground water between elevation -16 and -23 ft msl, o A dewatering point in the Emergency Feed Water (EFW) pump house located-north of containment at -31 ft msl, o A dewatering point located in the Residual Heat Removal (RHR) B-Equipment vault at elevation -61 on the northwest side of containment, and* .2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 15 of 51 Dewatering points in the B Electrical Tunnel at elevation -20 west of the EFW location that cycles ground water between -23 and -26 ft msl.The dewatering systems have been utilized since the early 2000's and samples of the extracted ground water have been periodically analyzed for tritium. The tritium concentrations in the withdrawn ground water since the dewatering was initiated are illustrated in Figures 13 through 16 for CEVA, PAB, EFW, RHR and B Electrical Tunnel dewatering locations. Initial tritium concentrations in the CEVA and PAB were elevated as tritium concentrations ranged up to 3,560,000 pCi/L in CEVA in early 2003 and 84,000 pCi/L in PAB in early 2000 (Figures 13 and14). Tritium concentrations have significantly decreased in both locations over the last three to five years as CEVA tritium concentrations have typically been below 50,000 pCi/L and PAB tritium levels have generally been below 5,000 pCi/L (Figures 13 and 14). The decrease in ground water tritium concentrations is related to the non-metallic liner that was added to the Cask Handling and Fuel Transfer Canal in the September 2004.Tritium concentrations in the ground water extracted from RHR and EFW have been much lower over the 2002 through 2009-time period. RHR tritium concentrations have generally ranged from 500 pCi/L to 1,800 pCi/L and EFW tritium levels have typically varied from 500 pCi/L to 2,640 pCi/L (Figures 15 and 16). The dewatering effort in the B Electrical Tunnel was recently initiated and tritium values are similar to those recorded in the RHR (Figure 15).RSCS has reviewed the tritium ground water concentrations from the dewatering systems as a function of the rate of ground water removal over time, and no correlation between the Withdrawal rates or tritium concentration was observed at any of the five locations. The five dewatering poi.nts are removing tritium-contaminated ground water that has migrated into subsurface adjacent to building foundations. These data suggest that tritium-contamination is present in site ground water at detectable concentrations proximal to these dewatering locations. The B Electrical Tunnel and EFW pumping locations are located on the northwest and northeast side of containment, respectively, while the CEVA and PAB pumping locations are on the southwest and southern side of containment. The RHR pumping well is located west of containment. The tritium concentrations are much higher for the CEVA and PAB pumping locations, indicating that the more significant tritium ground water concentrations are on the southwestern and southern side of the Unit 1 containment. Based on the~average daily withdrawal rates, the five dewatering locations in the Unit 1 containment area remove approximately 3,195 gallons of water per day (Table 6).Using the average tritium concentration measured in the withdrawn water during the January through April 2009 time period, the daily amount of tritium that is removed from Site dewatering activities is approximately 18,265,197 pCi/day (Table 6). r 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 16 of 51 Tritium in ground water is potentially a function of diffusion of tritium from tritium-contaminated concrete that was impacted during the original r'elease associated with the Cask Loading Area/Transfer canal in 1999. This makes identification of specific locations where contamination from concrete enters site, water difficult to determine. However, changes in dewatering rates and dewatering locations since the mitigation of the "leak" was completed, in conjunction with the complexity of the subsurface structures proximal .to the area warrant ongoing, long term monitoring of site ground water to verify that tritium concentrations continue to show a decreasing trend over time. Figures 13 through 16 show the tritium concentrations associated with the five ground water withdrawal locations, and indicate relatively constant tritium ground water concentrations since the 2004-2005 time period.A monitoring network of 15 monitoring wells was established in 2004 with the addition of four monitoring wells in the 2007/2008-time period. These wells have been periodically sampled and analyzed for tritium from the 2004 to 2009-time period. The monitoring network includes wells screened in both the surficial and bedrock aquifers, and wells located in upgradient and downgradient locations relative to the tritium contaminated area adjacent to Unit 1 containment (Table 1 and Figure 2). Tritium concentrations in all bedrock monitoring wells and most surficial wells over the 2004 through 2009-time period are below the minimum detectable activity (MDA). One exception is monitoring well SW-1 where tritium has ranged from 601 pCi/L to 2,930 pCi/L over the 2004 through 2009 time period (Figure 17).The distribution of tritium in Site ground water for both the surficial and bedrock aquifers is shown in Figures 18 through 23 for the fall 2004, March 2006, and June 2008-time periods. As indicated in Figures 18, 20, and.22, tritium in the surficial aquifer is limited to the area around the Unit 1 containment where tritium is detected in SW-I. Tritium concentrations in all bedrock monitoring wells are below the MDA, indicating that no measurable tritium is present in the bedrock aquifer (Figures 19, 21, and 23).The current tritium ground water data in the vicinity of the Unit 1 containment and fuel storage area indicate that tritium is.present in ground water above background levels and is derived from an onsite source in the area of the fuel storage building, consistent with the known release area of tritium that was identified in 1999. The tritium ground water data for 2004 through 2009 indicate that tritium is limited to the Unit 1 containment area, and no offsite migration of tritium in ground water has been observed. The current ground water withdrawal activities in the Unit 1 containment area is providing hydraulic containment for tritium in ground water at the Site.2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 17 of 51 4.0 SITE CONCEPTUAL MODEL This section presents a Site Conceptual Model for ground water flow and tritium migration at Seabrook Station.The Site is bounded on the northern, eastern and southern sides by a tidal marsh. The tidal marsh and the adjacent Browns River just north and east of the Site, drain into Hampton Harbor located approximately one mile east of the Site. The surface elevation of the Site is approximately +20 feet msl, and the elevation of the tidal marsh less than+5 feet msl.The subsurface geology in the area of Seabrook Station includes unconsolidated glacial till and post-glacial marine deposits above bedrock. The bedrock in the Site area includes metasedimentary quartzites, phyllites, and schists, and metavolcanic gneisses that are intruded by dioritic rocks. The foliation and joints in the bedrock have a strong easterly component that will enhance the ground water flow in the bedrock in the easterly direction. During plant construction, the native, unconsolidated soils were excavated down to the bedrock, and many of the foundations were poured directly on the bedrock surface. Up to 25 feet of engineered fill was used to backfill the foundations and bring the Site to current grade.Two aquifers are present at the Site. A surficial aquifer occurs within the engineered fill and a bedrock aquifer is present in the bedrock below. Quantitative ground water flow has been characterized in both aquifers, as synoptic ground water levels have been collected at the Site. Ground water in both aquifers generally flows to the east, discharging to the tidal marsh on the east and southeast side of the Site. The easterly flow in the bedrock aquifer is consistent with east-west oriented foliation and fractures, and with discharge to the tidal marsh on the eastern side of the Site.Ground water in the surficial aquifer flows to the east across the western portion of the Site with a relatively steep gradient. As ground water in the surficial aquifer flows across the eastern portion of the Site it is impacted by deep foundation structures in the containment areas, the sheetpile wall on the northern side of the facility, and ground water pumping activities. 'The presence of the deep foundation structures acts to restrict ground water-flow and create a flat hydraulic gradient in the area of Unit 1 and the Turbine Building. The sheet pile structure minimizes discharge along the northern side of the Site and artificially elevates the water table in that area, also acting to reduce the hydraulic gradient in northeastern portion of the Site.Ground water is continuously pumped in the Unit 2 containment area to prevent ground water inflow and the pumping activity creates a ground water depression that reverses 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-'19 Rev 01 Page 18 of 51 the ground water flow direction along the southern portion of the Site south of Units 1 and 2. In this area, ground water from the tidal marsh flows onto the Site.A tritium release from the Unit 1 spent fuel system, refueling canal, and cask handling area liners was identified in 1999. The leak was characterized and appropriate corrective actions were initiated. As part of the corrective actions, ground water withdrawal was initiated and incorporated into the remedial program at five locations within and nearby the release area, and a monitoring well network was established in both the surficial and bedrock aquifers.Tritium has been detected at concentrations up to 3,000 pCi/L adjacent to the release area in the surficial aquifer. Tritium sampling results for the monitoring well network for the 2004 through 2009-time period indicate that tritium is restricted to the Unit 1 containment area in the surficial aquifer and is below the MDA in the bedrock aquifer.The sampling results indicate that the ground water withdrawal activities in the area around Unit 1 containment has minimized tritium migration in Site ground water.If tritium-contaminated ground water in the surficial aquifer migrated away from the Unit 1 area, it would flow in an east-northeasterly direction and discharge to the tidal marsh east of SU-1 1, SD-3, and SD-2 (Figure 3).Currently, tritium in ground water at the Site does not present an environmental or health risk to onsite or offsite receptors. Municipal drinking water is supplied to the Site and most of the surrounding area. Surface water at the site from direct precipitation and process water is conveyed off the site through a permitted outfall, which discharges to the Atlantic Ocean approximately one mile offshore. The ground water sampling results and the water level measurements indicate that the current hydraulic controls implemented at the Site are limiting tritium to the onsite locations in the Unit 1 containment area. Based on these current data, the low tritium concentrations in the surficial and bedrock aquifers do not present a risk to public health and the environment. 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 19 of 51 5.0 RECOMMENDATIONS Based on this SCM, the following recommendations are developed by RSCS for Seabrook Station: Maintain a quarterly ground water sampling-program that integrates tritium monitoring with the license extension sampling program, which will include cation (calcium, sodium, potassium, and magnesium)-anion (chloride, sulfate, carbonate and bicarbonate) analysis for all monitoring and extraction wells. The cation- anion-data will characterize the site ground water, provide a basis for evaluating inflow of tidal marsh ground water, and identify any potential impacts associated with de-icing activities. The quarterly sampling program should be, conducted for at least one year to assess any seasonal variations and evaluate the hydraulic controls implemented to contain tritium in the Unit 1 area;o Conduct synoptic ground water level measurements on a quarterly basis for a minimum of 1 year following the currently proposed changes to the site dewatering system, and refine quantitative interpretation of ground water flow in surficial and bedrock aquifers;o Additional characterization of the Site downgradient of the fuel pool historic release area and potential sources in the PAB should be implemented as well as upgradient of the Unit 2 Containment. The new well locations should include downgradient surficial monitoring wells between existing well pairs SD-2/BD-3 and SD-3/BD-4 and downgradient of SW-1 near the Service Water pump house.A monitoring well located on the west side of Unit 2 should be included to provide a more complete understanding of the area that is influenced by Unit 2 pumping activities. The proposed monitoring wells would provide a better characterization of the downgradient ground water flow and tritium distribution at the Site; and o Re-evaluate SCM based on additional quarterly data.o Develop a three-dimensional numerical ground water flow model capable of evaluating site dewatering, ground water pumping, and tritium migration/containment. 2009 Site Conceptual Model -Seabrook Station RSCS, Inc., June 2009 TSD#09-19 Rev 01 Page 20 of 51

1.0 INTRODUCTION

Radiation Safety and Control Services (RSCS) has prepared this Technical Support Document (TSD) to assess the recent changes in tritium distribution in ground water at Seabrook Station. Historically, tritium has been reported in.a focused portion of the surficial aquifer adjacent to the fuel pool and Unit 1. More recently, tritium has been detected at concentrations in excess of the minimum detectable activity (MDA) in selected monitoring wells in both the surficial and bedrock aquifers.RSCS has recently developed a site conceptual model (SCM) for the Seabrook facility (RSCS, 2008 and 2009). The SCM includes the presence of two aquifers at the Site. A surficial aquifer occurs within the engineered fill and a bedrock aquifer is present in the bedrock below. Quantitative ground water flow has been characterized in both aquifers, as synoptic ground water levels have been collected at the Site. Ground water in both aquifers generally flows to the east, discharging to the tidal marsh on the east and southeast side of the Site.A tritium release from theUnit 1 spent fuel system, refueling canal, and cask handling area liners was identified in 1999. The leak was characterized and appropriate corrective actions were initiated. As part of the corrective actions, ground water (withdrawal was initiated and incorporated into the remedial program at five locations within and nearby the release area, and a monitoring well network was established in both the surficial and bedrock aquifers.Historically, tritium has been detected at concentrations up to 3,000 pCi/L adjacent to the release area in the surficial aquifer. Tritium sampling results for the monitoring well network during the 2004 through March 2009-time period have indicated that tritium has been limited to surficial monitoring well SW-1 located in the Unit 1 containment area, and has been below the MDA in the bedrock aquifer.In addition to the recent changes in the tritium distribution at the-Site, changes in the hydrology and ground water removal have also occurred at the Seabrook facility during the June through August 2009 time frame. Significant rainfall during the spring-early summer 2009 time period has raised ground water elevations in several monitoring wells to levels in excess of historic levels, and ground water withdrawal rates in the RHR vault have significantly decreased. The specific objectives of this TSD are to assess the new tritium detections, determine the likely reason(s) for the changes, and evaluate the potential impacts to ground water at the site. The assessment includes: Evaluation of ground water elevations and-ground water flow in the surficial aquifer;Evaluation of ground water pumping and withdrawal at the Site; and Tritium Distribution and Ground Water Flow at Seabrook Station RSCS, Inc., August 2009 TSD # 09-039 Revision 0 Page 5 of 31 o Evaluation of tritium distribution in the surficial and bedrock aquifers.2.0 TRITIUM DISTRIBUTION IN SURFICIAL AQUIFER Recent hydrogeologic studies at Seabrook Station have identified tritium in the surficial aquifer at concentrations ranging from 617 pCi/L to 2,930 pCi/L. The detected tritium has been limited to monitoring well SW-1 located adjacent to the Fuel Pool (Figure 1)(RSCS 2008 and 2009). Through March 2009, tritium has not been detected above the MDA in monitoring wells in the surficial aquifer or bedrock aquifer except for SW-1.More recently, tritium has been detected in monitoring wells SD-1 and BD-2 located approximately 75 feet southwest of SW-1 (Figure 2). Monitoring well SD-1 is a shallow well screened in the surficial aquifer and BD-2 is a deeper monitoring well in the bedrock aquifer. Tritium has been detected at concentrations ranging from 969 pCi/L to 2,360 pCi/L in SD-1 and 832 pCi/L to 1,880 pCi/L in BD-2 over the June through August 2009 time period, while concentrations in SW-1 remained consistent with historic values (Figure 3). During this time period, the tritium concentrations in SD-1 are typically greater than those observed in BD-2, with the highest values associated with SW-1 (Figure 3).Prior to March 2009, the tritium distribution at the site was limited to the area around Unit 1 and SW-1 in the surficial aquifer (Figure 4). Based on the consistent detection of tritium in SD-1 over the June through August 2009 time frame a larger area of tritium-contaminated ground water has been identified for the surficial aquifer, and the 1000 pCi/L isopleth is now shown to include monitoring well SD-1 (Figure 5).2.1 GROUND WATER ELEVATIONS AND GROUND WATER FLOW During the June through August 2009 time period, the ground water elevation in SD-1 has been slightly less than that measured in SW-1, confirming that SD-1 is downgradient of SW-1 (Figure 6). The downgradient relationship between SW-1 and SD-1 is consistent with the migration of the tritium plume established at SW-1 moving towards and encompassing SD-I. The ground water elevation relationship between SW-1 and SD-1 through time is shown in Figure 7. While SW-1 commonly has a ground water elevation greater than that observed in SD-1, there are several occasions when this is not the case. During the spring when higher ground water levels are observed, SW-1 typically has a higher water level than that observed for SD-1 (Figure 7). The fall time period, where ground water levels are lower, exhibits several occasions where the ground water level in SD-1 is greater than that observed in-SW-1 (Figure 7). These observations indicate that ground water flow at SD-1 is generally side gradient with respect to SW-1, consistent with the ground water flow map established during spring 2009 (Figure 8) (RSCS, 2009)'Tritium Distribution and Ground Water Flow at Seabrook Station RSCS, Inc., August 2009 TSD # 09-039 Revision 0 Page 6 of 31 While the ground water elevations in SW-1 and SD-I are similar,.during high water level conditions theground water elevation in SW-1 is always higher than that observed in SD-1 (Figure 7). During the June, July and August 2009 time period, the ground water elevations measured in SD-I and SW-1 are significantly higher than that historically observed during summer time period.(Figures 6 and 7). The increased ground water elevations are in response to significant rainfall in the spring and early summer time period (Figure 6). During the summer 2009-time period, the ground water elevation difference between SW-1 and SD-1 is commonly 0.5 feet (Figure 6). Historically, during the June through August time period the ground Water elevation difference between the two wells has been closer to 0.2 feet (Figure 7). Based on these relationships, the migration of the tritium plume towards SD-I potentially appears to be a function of the high water levels established during the June, July and August 2009 time period, and the resulting hydraulic gradient established between SW-1 and SD-i.2.2 IMPACTS RELATED TO GROUNDWATER WITHDRAWAL Ground water pumping/withdrawal activities are ongoing at several locations at the Site.Approximately 32,000 gallons per day (gpd) of ground water is pumped from the Unit 2 containment building to control inflow of ground water. This ground water removal in Unit 2 gives rise to a ground water depression near SW-3 and reverses the ground water gradient in the SW-1 and SD-1 area (Figure 8). The ongoing pumping and ground water withdrawal in the Unit 2 area is not believed to have effected any recent changes in the hydrology at the Site.Ground water withdrawal activities have also been focused on the Unit I containment area to minimize ground water inflow to the buildings. A total of five locations'have regularly withdrawn ground water under hydrostatic conditions in the Unit 1 area at a combined rate of approximately 3,000 gpd (Figure 9). The most significant location of ground water withdrawal is located in the RHR vault at an elevation of -61i feet MSL.Over the past several years, this location has removed approximately 1,500 to 2,000 gallons per day (Figure 10). During early July, the RHR ground water withdrawal rate decreased to levels below 200 gallons per day (Figure 10). Aside from the change in RHR withdrawal rate, no other changes in the pumping or withdrawal rate have occurred in this portion of the site. Evaluation of the potential impact of the decreasing RHR pumping rate and ground water elevation are summarized in Figure 11 where hydrographs of SW-1, SD-1, BD-2 and 14-inch well are graphed along with the RHR pumping rate. Monitoring wells SW-1, SD-1, and BD-2 are part of the 19-well.monitoring network at the Site, while the 14-inch well is a deep 14-inch casing that is tied into a french drain system around the Unit 1 Containment that was historically used for dewatering during construction of the facility.As summarized in Figure 11, ground water elevations in SW-1, SD-1, and BD-2 do not change in response to decreasing withdrawal rate in RHR. The only consistent Tritium Distribution and Ground Water Flow at Seabrook Station RSCS, Inc., August 2009 TSD # 09-039 Revision 0 Page 7 of 31 response to decreasing ground water withdrawal in the RHR is the increasing ground water level observed in the 14-inch well during the July time period (Figure 11). All four monitoring wells have a decreasing elevation in August as a function of the decreased precipitation relative to that experienced in spring and early Summer 2009 (Figure 6). The increase in ground water elevation observed in the 14-inch well suggests that the french drain system may have a hydraulic connection with the RHR vault. The change in RHR withdrawal rate does not appear to play a significant role in the recent change in tritium distribution at the Site.3.0 TRITIUM DISTRIBUTION IN BEDROCK AQUIFER The presence of detectable concentrations of tritium in monitoring well BD-2 is not consistent with historic observations at Seabrook Station. The only tritium detections in the bedrock aquifer have occurred in monitoring well BD-2 during the June through August 2009 time period (Figure 3). The tritium concentrations in BD-2 during the June-August-time period ranged from below the MDA to 1,880 pCi/L. Tritium was first detected in a sample from BD-2 (1,565 pCi/L) on June 20, 2009. From June 20 to July 22, 2009 tritium decreased to 866 pCi/L, and was below the MDA from July 27 to August 15, 2009. Tritium was again reported above the MDA on August 24, 2009 at a concentration of 1,104 pCi/L.3.1 BEDROCK WELL CONFIGUATION The tritium detections in the bedrock aquifer may be related to the physical construction of the bedrock well, as the bedrock wells installed at Seabrook Station are not consistent with typical monitoring well construction. The bedrock wells do not include PVC well construction material (i.e. riser and well screen), but are simply metal well casing installed through the overburden material and seated into bedrock. Below the seated metal casing an open bedrock hole is present to the bottom of the boring (Table 1). This configuration allows access to the bedrock aquifer, but may not provide a permanent seal between the surficial and bedrock aquifers and provides the potential for ground water to flow into the well through well casing joints. The casing material is most likely installed as 10-foot sections and at least one casing joint is located in the well casing installed through the 20 feet of overburden material. The current configuration.of BD-2 indicates that a well casing joint is most likely located approximately 10 feet below grade at approximately 10 feet MSL. This casing joint is threaded, but is not watertight. If the water level in the surficial aquifer in the BD-2 area exceeds the elevation of the casing joint (approximately 10 feet MSL), ground water from the surficial aquifer has the potential to flow into the bedrock well through the casing joint.Tritium Distribution and Ground Water Flow at Seabrook Station RSCS, Inc., August 2009 TSD # 09-039 Revision 0 Page 8 of 31 3.2 EVALUATION OF GROUND WATER LEVELS IN BD-2 AND SD-I Monitoring wells SD-i and BD-2 represent a shallow/deep monitoring well pair and are located adjacent to one another in, the southern portion of the Site southwest of Unit 1 (Figure 1). Water levels from both monitoring wells have been measured since 2004 and hydrographs for the monitoring wells are summarized in Figures 12 and 13'. Also included in Figures 12 and 13 is the elevation of the casing joint in BD-2 that is located at approximately 10 feet MSL. 'The water elevations in the surficial aquifer for SD-i from 2004 through March 2009 are consistently below the elevation of the casing joint in BD-2, and indicate that groundwater in the surficial aquifer in the vicinity of BD-2 is at too low an elevation to flow into BD-2 (Figure 13) through the suspect casing joint.In contrast to the historic water levels in SD-i during the 2004 through March 2009 time period, ground water elevations in SD-I consistently exceed the 10-foot MSL casing joint elevation in BD-2 during the July and early August 2009 time period (Figure 12).During this time period the tritium plume in the surficial aquifer has migrated to SD-1 and tritium-contaminated ground water has the potential to flow through the casing joint into BD-2. The tritium concentration in BD-2 is typically less than that observed in SD-1, consistent with source of tritium in BD-2 being related to ground water from the surficial aquifer flowing into BD-2 (Figure 3).The decrease in tritium concentration in BD-2 during late July and early August 2009 occurs during the time period when decreasing water levels in SD-1 bring the ground water elevation of the surficial aquifer in SD-1 to levels at or below the presumed elevation of the casing joint in BD-2 (Figures 3 and 12). This relationship further supports the concept that the source of tritium in BD-2 is from inflow of the tritium-contaminated surficial aquifer through the casing joint.Assuming a flow rate in the range of 1 to 10 gallons per hour over the June through mid-July time period, 1,000 to 10,000 gallons of tritium-contaminated ground water could have flowed from the surficial aquifer into BD-2 and impacted the bedrock aquifer in the vicinity of BD-2.3.3 GROUNDWATER PUMPING AND TRITIUM ANALYSES IN BD-2 To assess the tritium concentrations in BD-2, two small-scale pumping tests were conducted in BD-2 on July 8 and July 10, 2009. During the pumping tests, ground water samples from BD-2 were periodically taken and analyzed for tritium. The results of the ground water drawdown and associated tritium concentrations for the July 8, 2009 pumping test are summarized in Figure 14.The initial drawdown in BD-2 to 31 feet is associated with a small decrease in tritium (Figure 14). The tritium concentration further decreases to 929 pCi/L during the middle Tritium Distribution and Ground Water Flow at Seabrook Station RSCS, Inc., August 2009 TSD # 09-039 Revision 0 Page 9 of 31 portion of the pumping test and rebounds to pretest values at the end of the pumping test (Figure 14). The pumping test was conducted during the time period when tritium-contaminated groundwater from the surficial aquifer was potentially flowing into BD-2, and the rebound in tritium concentration at the end of the pumping-test may reflect this, process. Similar results were observed in the second pumping test conducted on July 10, 2009.The results of the two pumping tests do not provide significant insight to the presence-of tritium in BD-2. If tritium-contaminated ground water has been flowing into BD-2 over the June and early July time period, thousands of gallons of tritium-contaminated ground water would have potentially flowed into the monitoring well over that time period, and the removal of 120 and 170 gallons, respectively of ground water from BD-2 during the pumping tests on July. 8 and July 10, 2009 would not have removed enough tritium-contaminated ground water from the bedrock aquifer to effect significant changes in the tritium concentration measured in BD-2. Likewise, the potential for tritium to flow into BD-2 through the casing joint would also potentially impact the measured tritium concentration during the pumping test.

4.0 CONCLUSION

S This TSD has evaluated distribution of tritium in the surficial and bedrock aquifers at Seabrook Station. While the presence tritium has historically been limited to monitoring well SW-1 screened in the surficial aquifer and located adjacent to Unit 1, recent analyses has indicated the presence of tritium in nearby monitoring wells SD-1 (surficial aquifer) and BD-2 (bedrock aquifer) over the July and August 2009 time period. To assess the changes in tritium distribution in site ground water, RSCS has evaluated two changes in the hydrology in the vicinity of SW-1, SD-1, and BD-2 that have occurred during the spring-early summer 2009 time period.Changes in the ground water withdrawal rate in the RHR have been shown to have no significant impact on ground water elevations in SW-1, SD-1 and BD-2 or ground water flow in the surficial and bedrock aquifers in the vicinity of the monitoring wells.In contrast, the impact of significant precipitation in the spring-early summer time period has significantly increased ground water elevations in the surficial aquifer. The increases in the elevation of the water table in the surficial aquifer have resulted in subtle changes in the ground water gradient in the vicinity of SW-1 and SD-1. The increased gradient between SW-1 and SD-1 has resulted in southwestern migration of the tritium plume established at SW-1 to include SD-1 (Figure 5).The increased ground water elevations in the surficial aquifer during the spring and early summer time period have also resulted in tritium-contaminated ground water from the surficial aquifer flowing into monitoring well BD-2 via the likely presence of a casing joint. The elevation of the casing joint in BD-2 has historically been above the level of Tritium Distribution and Ground Water Flow at Seabrook Station RSCS, Inc., August 2009 TSD # 09-039 Revision 0 Page 10 of 31 the water table in the surficial aquifer, however the high water levels in the surficial aquifer during the June and July time period have exceeded the casing joint elevation, resulting in the flow of tritium-contaminated ground water into BD-2 (Figures 12 and 13).Assuming a flow rate of 1 to 10 gallons per hour, approximately 1,000 to 10,000 gallons of tritium-contaminated water has potentially flowed from the surficial aquifer into BD-2 over the June and July time period.5.0 RECOMMENDATIONS Based on the conclusions of this TSD, the following recommendations are provided by RSCS for Seabrook Station:* Assess the surficial aquifer along the facility boundary south of SD-1 for the presence of tritium. The potential exists for the tritium plume to have migrated to the south and southwest towards the adjacent tidal marsh;* Perform a down-hole geophysical investigation of BO-2, and other bedrock monitoring wells of similar construction, to verify the construction details of the well(s). This information will allow for the design of 2 inch, bedrock aquifer(isolated wells, within each existing well.* Complete the installation of two-inch monitoring wells within the four-inch bedrock well casings. These new monitoring wells will minimize the potential for migration of ground water from the surficial aquifer to the bedrock aquifer. The new monitoring wells will also provide a more complete characterization of vertical gradients between the surficial and bedrock aquifers; and Develop a three-dimensional numerical ground water flow model capable of evaluating dewatering, ground water pumping, and tritium migration/containment at the Site.Tritium Distribution and Ground Water Flow at Seabrook Station RSCS, Inc., August 2009 TSD # 09-039 Revision 0 Page 11 of 31

The cause for the oil spill was improper assembly of the connection between the flush hose sections.-November 2000 In November 2000, a leak was discovered in the underground fuel supply -line from the Auxiliary Boiler Fuel Oil Tank. The tank and steel fuel lines were None 7 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC June 2009 installed in 1977. Excavation of the fuel line revealed a1/4-inch hole in the four-inch supply line to the Auxiliary Boiler. The fuel line was immediately repaired.Contaminated soil was removed prior to replacement of both 1,200-foot sections of the fuel line and return line during the summer of 2001. This replacement was accomplished by inserting a new line inside the old lines.The results of the Site Investigation, which included soil borings and monitoring wells, indicated that no residual source of oil was present. Concentrations of contaminants in groundwater (specifically MTBE) at levels slightly greater than the ambient groundwater quality standards remain. Groundwater sampling, as directed by NHDES. continues in this location.4 I.March 2001 In March 2001, a leak was discovered in the underground gasoline and diesel fuel lines at the Vehicle Maintenance Shop. This 40-foot long piping system was installed in 1993 and consisted of two-inch diameter pipes with a corrosion protection wrapping. The fuel release did not impact surface waters either directly or via the storm drainage system. Contaminated soil was removed prior to installation of a new pump station. A Site Investigation including soil borings and monitoring wells was performed. Groundwater samples obtained to-date indicate that concentrations of gasoline-related compounds continue to show a decreasing trend with no VOCs other than MTBE detected at levels above the ambient groundwater quality standards. Groundwater monitoring is ongoing.None The site Spill Prevention Control and Countermeasure (SPCC) Plan (Reference 3.4) contains a full description of the historical large oil spills on site.2.3 Non-Stormwater Discharges Documentation The presence of non-storm water discharges was evaluated in two phases both of which where completed during 1993-1994. Phase I involved a plant schematic review and Phase II verified the review with a visual inspection of the drains. Power plant effluents and a large part of the Seabrook Station site (Subarea A) discharge into the storm drain system that in turn discharge into the Circulating Water System (at Manhole 34). The discharge of the Circulating Water System (Outfall 001) is controlled and monitored under the NPDES Permit.8 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC June 2009 The Station Drain Table Reference (Reference 3.3) lists the results of the evaluation and includes those drains (roof, floor, equipment, etc.) that discharge directly to the storm drain system.Excluded are those drains that first discharge to a NPDES-monitored outfall, such as an oil/water separator, before discharging to the storm water drain system. Reference 3.3 also includes the drain type, any contaminants -in the vicinity, the type of BMP in place, and the likelihood of a material release causing storm water pollution. Attachment B contains a certification of the results.Other non-storm water discharges include* Fire hydrant flushing* Potable water sources, including waterline flushings Air conditioning condensate

• Discharges.

from naturally occurring streams* Routine exterior building wash-down that does not use detergents or other compounds Pavement wash waters where detergents are not used and where leaks or spills of hazardous materials have not occurred* Dewatering of building groundwater inleakage* Dewatering operations that may occur during the performance of construction activities The locations of the discharges described above occur throughout Seabrook Station and are too numerous to individually identify in Figure 5. These discharges may be made to New Hampshire surface waters either through Outfall 001 or directly via sheet runoff. Each is administratively controlled either by procedures or routine inspection. All dewatering operations are administratively controlled and include the following:

1.

of ground water to New Hampshire Surface Waters 2. Return of ground water to the ground without a discharge to New Hampshire Surface-Waters

3. Removal of storm water that has collected on site Case 1: The routine discharge of groundwater to NPDES Permit Outfall 001 (ocean discharge) is described in the documentation that supports the renewal of Seabrook Station's NPDES Permit ,(effective April 2002).Dewatering of several plant buildings (Containment Annulus, Primary Auxiliary Building, Yard Equipment Vaults and Fuel Storage Building) may contain small amounts of radioactive tritium.9 StormwaterPollution Prevention Plan (SWPPP)NextEra Energy Seabrook,-LLC June 2009 The groundwater dewatering system discharges directly to the storm drain system which flows via Manhole 34 in the Circulating Water System Junction Box Wet Weather Discharge to Outfall 001 (Ocean Discharge).

Radioactive discharges are addressed in Seabrook Station's NPDES Permit Part I.A. 10 for Outfall 001 (ocean discharge), which states that the discharge of radioactive materials shall be in accordance with the Nuclear Regulatory Commission (NRC) requirements (10 CFR 20 and the Seabrook Station Operating License, Appendix A, Technical Specifications). The following guidance is used in determining the requirements for the discharges of groundwater to Outfall 001: 1 If the groundwater is being removed from an area that has no history-of soil contamination, measures shall be taken to avoid the discharge of silt.The effluent shall also be inspected for an oil sheen or odor, which are indications of oil or chemical contamination. If there is an indication of contamination, the discharge must be terminated.

2. If the groundwater is being removed from an area that has a potential history of soil contamination or known history of soil contamination, such as areas near the Vehicle Maintenance Facility or Auxiliary Boiler fuel-line, then a Temporary Surface Water Discharge Permit will be acquired from the New Hampshire Department of Environmental Services and the Environmental Protection Agency in accordance with Env-Ws 1505. This permit will specify the water discharge parameters, treatment methods, water quality sampling requirements and reporting requirements.

Case 2: Groundwater may be returned to the ground if it does not reach surface waters such as the surrounding wetlands and may proceed using the following guidance: 1. If the groundwater is being removed from an area that has no history of soil contamination, the water can be returned to the ground. and allowed to percolate into the ground provided none of the water runs off into a surface water. The groundwater shall be inspected for an oil sheen or odor, which are indications of oil or chemical contamination. If there is an indication of contamination, the discharge must be terminated.

2. If the groundwater is being removed from an area that has a potential history of soil contamination or known history of soil contamination, the New Hampshire Department of Environmental Compliance Groundwater Protection Bureau must be contacted prior to discharging the effluent back to the ground.Case 3: Storm water from precipitation is an expected discharge to Outfall 001 or nearby wetlands.

Therefore, if a depression or excavation contains known storm water, it can be returned directly to the ground or can be routed to Outfall 001. The discharge of silty water should be avoided.10 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC June 2009 2.4 Salt Storage 1.

These include operation practices, material inventory practices, and material storage practices. These practices are identified, performed, and reviewed through the work order system (Reference 3.8), which establishes the administrative controls for repetitive tasks. Where practicable, large dumpsters for trash or industrial materials have covers to prevent exposure to precipitation.

3.3 Maintenance

Station preventive maintenance uses the Repetitive Tasks system as well as departmenf procedures to provide timely inspection and maintenance of storm water management devices.The tasks include maintenance of oil/water separators. Catch basins are cleaned periodically on an as-needed basis to remove sand and silt.3.4 Spill Prevention and Response Seabrook Station maintains the Spill Prevention Control and Countermeasure (SPCC) Plan and the Oil and Hazardous Substances Pollution Contingency Plan. Together, these plans identify potential oil and hazardous materials pollution sources, provide physical structures and systems to prevent discharge, and the resources (both personnel and equipment) available to implement cleanup if it is needed..12 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC June 2009 3.5 Erosion and Sediment Controls Various sediment and erosion control measures have been implemented. These include road paving and traffic control; regular street sweeping and catch basin maintenance; grading, seeding, and construction of diversion structures. In addition, regular Licensing Department Surveillances are conducted (see §5.3.4).3.6 Management of Runoff Two routine inspection programs are conducted by site personnel to review designated equipment and areas for leaks and potential sources of pollution. These include: Nuclear Systems Operator routine inspections of Station-related equipment and areas.Licensing Department surveillances and inspections of the nonradiological aspects of the Environmental ComplianceProgram. Licensing personnel perform routine quarterly environmental surveillances of the Seabrook Station site and initiate a corrective action program document (Condition Report) as necessary. The purpose of these broader environmental inspections is to identify and correct items which are not in compliance with applicable environmental regulations or site policies and procedures. These items include leaks from tanks, equipment, transformers or stored materials including chemicals or compressed gases, erosion, and debris.The quarterly inspections of the site are performed in accordance with the Licensing Department Site Environmental Surveillance Instruction (ENV-4).Deficiencies in implementation of the Storm Water Pollution Prevention Plan identified during these inspections are corrected within 14 days of discovery in accordanrce with the Storm Water Multi-sector General Permit.3.7 Salt Storage Piles or Piles Containing Salt Sand mixed with salt is used on site roads and walkways for deicing. The sand/salt is stockpiled in the former Hazardous Waste Facility structure west of the Production Warehouse (Figure 5).A smaller storage area is located at the west end of the Clorination Building. The sand/salt is stored in roofed structures at all locations. Covers are also used to reduce blowing of sand/salt piles.13 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC June 2009 3.8 MSGP Sector-Specific Non-Numeric Effluent Limits Does not apply to Nuclear Utility.3.9 Employee Training Seabrook Station maintains the Training and Qualification Program to identify training needs-(Reference 3.14). All station personnel, including contractors, receive environmental awareness training. In addition, every employee receives. annual Plant Access Training (PAT), which addresses topics such as spill identification and response, good housekeeping, and material management practices. Station personnel, whose work involves significant environmental aspects, receive specialized training to minimize impacts (Reference 3.13). For instance, Fire Brigade personnel receive training as primary responders to hazardous material spills or releases. In addition, a Spill Event Response Team (SERT) is trained in the control and cleanup of oil and hazardous material spills, including the use of equipment maintained on site (see Reference 3.4).3.10 Non-Stormwater Discharges Reference Section 2.3 3.11 Waste, Garbage and Floatable Debris Trash is disposed in dumpsters staged in the vicinity of selected site buildings. A central trash disposal area has also been established on the southern side of Rocks Road in the "G" parking area. This area has three roll-off style dumpsters for trash, metal and wood. A trash hauler and metal recycling vendor periodically remove the dumpster contents. The central area is periodically surveyed to. ensure good housekeeping and proper disposal of authorized materials. 3.12 Dust Generation and Vehicle Tracking of industrial Materials Construction projects having the potential to generate significant dust will incorporate measures to control.the amount generated. Generally surface wetting will be used as the primary control mechanism. Construction projects will' also consider the potential for industrial material to be tracked away from the construction area by vehicles. Control measures such as pressure washing vehicles when exiting the construction area will be used as required.14 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC June 2009 SECTION 4: SCHEDULES AND PROCEDURES FOR MONITORING Benchmark Effluent State or Tribal Other(as Monitoring (2008 Limitations Specific Impaired Waters required by EPA MsGP, Part Guidelines S Monitoring 2008 MSGP Part 6.2.1)* Monitoring Monitoring 6.2.5)Storm Drain Rad Reference Sample Monitor and Procedure CP n/a n/a n/a Locations North Road Delivery Access 9.1-Figure

6.2 Documentation

Regarding Historic Properties Industrial facilities are eligible for coverage under the Storm Water Multi-sector General Permit (MSGP) if their storm water discharges do not affect a property that is listed or is eligible for listing on the National Register of Historic Places (per MSGP Section 1.2.3.7). The following information documents the basis for Seabrook Station's eligibility for cove-rage under the MSGP wNith respect to historic places. Seabrook Station's storm water discharges and non-storm water discharges do not have the potential to affect property that is either listed or eligible for listing on the National Register of Historic Places since no historic properties are located in the vicinity of the locations where storm water discharges reach the receiving waters that includes the surrounding salt marsh and Atlantic Ocean. This condition meets the MSGP Addendum B Eligibility Criteria 1.A review of the National Park Service National Register of Historic Places website (http://www.nr.nps.gov/) for Rockingham County, New Hampshire identified no historic places in the Town of Seabrook. Several Historic Places were identified in the adjoining towns of Hampton and Hampton Falls. However, none of these historic places are in the path of Seabrook Station's storm water and non-storm water discharges or where construction activities may be planned to install best management practices (BMIPs) to control such discharges.

6.3 Documentation

Regarding NEPA Review (if applicable) This requirement is not applicable to Seabrook Station. Seabrook Station does not discharge stormwater that is subject to New Source Performance Standards stormwater-specific effluent limitations guidelines (ref: Section 1.1.2.5 of General Permit and Table 1-1) thus there is no NEPA review documentation. 16 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC June 2009 SECTION 7: SWPPP CERTIFICATION-I certify under penalty of lawthat this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted.

The June August 2002 total Drain Rad Analysis recoverable iron levels of 1.5 mg/l andl 0.0 mg/l respectively, Monitor were higher than the benchmark level of 1.0 mg/l. These atypical benchmark results were attributed to the fact that the storm water samples were collected after periods of extended dry weather.This condition allowed normal standing storm .water in the storm drain system to be in contact with metal surfaces for a prolonged time thus concentrating the iron oxide in the storm drain system water which normally would be flushed away by periodic rainfall events. The follow-up benchmark storm water sample collected on October 16, 2002 -after rainfall had returned to more normal frequencies -had a total recoverable iron level of 0.21 mg/l which is below the benchmark level. Note: this follow-up benchmark sample was collected after the MSGP Year 2 (October 1, 2001 to September 30, 2002).

Dear Mr. O'Keefe:

This responds to your recent correspondence requesting information on the presence of federally-listed and/or proposed endangered or threatened species in relation to the Seabrook Station (Station)in Seabrook, New Hampshire. FiL Energy Seabrook Station plans to apply to the Nuclear Regulatory Commission for renewal of the Operating License for 20 years beyond the current expiration date of Marmb 15, 2030.No federally-listed or proposed, threatened or endangered species or critical habitat under the jurisdiction of the U.S. Fish and Wildlife Service are known to occur in the project areas. However, the federally-threatened piping plover (Charadrius melodus) is known to nest on the coastal beaches located approximately

1.8 miles

cast of the Station. This office is not aware of any impacts to the piping plover that could be attributed to the operation of the Station. In addition, the federally-endangered roseate tern (Sterna dougallii) is known to occur in the coastal waters ofNew Hampshire and is likely to be found in the vicinity of the cooling water intake and discharge structures. Because these structures are located approximately

1.3 miles

offshore in about 60 feet of water, no effects to the roseate tern or its habitat are known or anticipated. Preparation of a Biological Assessment or further consultation with us under Section 7 of the Endangered Species Act is not required.While there are no occurrences of federally-listed species in the project area, the New England cottontail (Sylvilagus transitionatis) is known to occur in the Towns ofDerry and Londonderry, New Hampshire. Furthermore, our records indicate that the New England cottontail has been recorded at a sitejust east of the Scobie Pond substation in Derry, New Hampshire. The U.S. Fish and Wildlife Service announced the New England cottontail as a Candidate Species for listing on September 12, 2006 in the Federal Register (50 CFR part 17). While the New England cottontail remains an official candidate species, there is currently no legal federal obligation to avoid affecting the habitat of the species. However, the New England cottontail is state-listed as an endangered species by the New Hampshire Department of Fish and Game (NHDF&G), and we suggest that you contact the NHDF&G for further guidance.3 Attachment D: Endangered Species and Historic Places Assessment (Sheet 4 of 16).Michael O Keefe 2 May 15, 2009 New England cottontails are considered habitat specialists; insofar as they are dependent on early-successional habitats typically described as thickets. In addition to New England cottontails demonstrating a strong affinity for heavy cover, they arc also reluctant to stray from it (>5 in), Habitats of this type are typically associated with beaver-flowage wetlands, idle agricultural lands, power line corridors, railroad right-of-ways, and patches of rcgcnerating forests, In contrast, castcrn cottontails (which can often be found living with New England cottontails) appear to have relatively generalized habitat requirements and can often be found in residential-type habitats, such as private lawns, golf courses, and active agriculture areas.Vegetation management along utility right-of-ways has a significant impact on the New England cottontail. In fact, there is strong evidence that take of New England cottontails has occurred as a result of powerline right-of-way management. Long-term management that converts scrub-shrub corridors into herbaceous covers serves to eliminate habitat and binder dispersal, while short-term management of shrubs serves as a temporary impact to habitat. These short-term impacts to shrub vegetation are necessary to ensure that successional forces do not proceed todthe point where habitat is no longer suitable for the New England cottontail. Given the conservation status of this species, a full federal listing in the future is probable. As such, it maybe beneficial to begin a discussion about how your company could manage habitat for this species.This concludes our review of listed species and critical habitat in the project locations and environs.referenced above. No further Endangered Species Act coordination of this type is necessary for a period of one year from the date of this letter, unless additional information on listed or proposed species becomes available. In order to curtail the need to contact this office in the future for updated lists of federally-listed or proposed threatened or endangered species and critical habitats, please visit the Endangered Species Consultation page on the New England Field Office's website: www.fws.gov/northeastlnewenglandfieldoftice/EndangeredSpee-Consultation.htm In addition, there is a link to procedures that may allow you to conclude ifhabitat for a listed species is present in the project area. If no habitat exists, then no federally-listed species are present in the project area and there is no need to contact us for further consultation. If the above conclusion cannot be reached, further consultation with this office is advised. Information describing the nature and location of the proposed activity that should be provided to us for further informal consultation can be found at the above-referenced site.4 Attachment D: Endangered Species and Historic Places Assessment (Sheet 5 of 16)M4ichael O Keefe 3IS, 2D09 Thank you for your coordination.

It protects wildlife and plant species in danger of nationwide extinction. 1979 -The New Hampshire Endangered Species Conservation Act was passed, giving New Hampshire Fish and Game Department the authority to protect wildlife in danger of becoming extinct in New Hampshire. 1980 -The first list of New Hampshire threatened and endangered wildlife was created.1987 & 2000 -The New Hampshire threatened and endangered wildlife list was revised.2006 -The first New Hampshire Wildlife Action Plan took effect.2008 -The current New Hampshire threatened and endangered wildlife list took effect on 9/20/08.The list of New Hampshire's endangered and threatened wildlife Is maintained by the New Hampshire Fish and Game Department. The list is used to determine protection and management actions necessary to ensure the survival of the state's endangered and threatened wildlife. State and federal agencies and numer-ous New Hampshire nonprofit conservation organizations work cooperatively to protect and manage the state's wildlife. The Fish and Game Department has legal authority regarding all wildlife, game, nongame and endangered or threatened species.This work is made possible through federal- grants, the sale of N.H. Conservation License Plates (moose plates) and private contributions. Donations to the Nongame Program are matched by state dollars.

Our mission Is to find, track, mid facilitate the protection of New Hampshire's rare plants and exemplary natural communities (which are essentially different types of forests, wetlands, grasslands, etc). We currently study more than 740 plant and animal species, 195 natural communities. Our database contains information on more than 5,500 species or natural community occurrences throughout the state.Plants, Animal, and Natural Communilies Tracked by the NiU Natural Heritage Bureau The following lists note the rare plants, rare animals, and exemplary natural communities that the NH Natural Heritage Bureau has on record in each town. This document may not be used as a substitute for NH Natural Heritage Bureau reviews that are required bythe Department of Environmental Services, Federal Energy Regulatory Commission, or any other local, state, or federal government agency. Afew species that are highly vulnerable to collection are not inclucled in the town lists. In addition, the list is dynamic: as new populations and natural communities are reported to our office, the list grows. Planners and interested residents should therefore contact the N-i Natural Heritage Bureau directly if they need up-to-date information or have questions.- Exremplary Vatural Communities Natural communities are basically different types of forests, wetlands, grasslands, etc.: formally defined as assemblages ofplants and animals that recur in predictable patterns across the landscape under similar physical conditions. Most of the New Hampshire landscape is covered by relatively common natural community types. Scattered throughout the state, however, and usually in predictable areas, are distinctive communities found in few other places.Particular sets of natural communities tend to co-occur in the landscape and are linked by a common set of driving forces, such as landforms, flooding, soils, and nutrient regime. These are referred to as natural community systems. Systems are at an appropriate scale for many conservation applications, including mapping and predictive modeling, correspondence to wildlite and wildlife habitats, and as direct conservation targets in conservation planning.The NH Natural Heritage Bureau tracks "exemplary" natural community and system occurrences-To qualify as exemplary, a natural community or system in a given place must be of a rare type, such as a calcareous riverside seep, or must be a very old occurrence ofa common community in good condition, such as an old-growth spruce -fir forest Rare Plant Species The NH Natural Heritage Bureau tracks the state's rarest and most imperiled plant species. We have identilied these plants in cooperation with researchers, conservation organizations such as The Nature Conservancy, and knowledgeable amateur botanists-We obtained plant locations from sources including herbarium specimens (some dating from the late 1800s), personal contacts, the scientific literature, and through extensive field research. The NH Natural Heritage Bureau undertakes surveys on private property only with landowner permission, Rare Animal Species The NH Natural Heritage Bureau tracks rare animal species in cooperation with the Nongame &Endangered Wildlife Program of the NH Fish & Game Department. The Nongame Program has idcntified these species in cooperation with researchers, conservation organizations such as the Audubon 9 Attachment D: Endangered Species and Historic Places Assessment (Sheet 10 of 16)Nl-IINaiural lerfltag Bureau'Society of New Hampshire, Iiowledgeable amateur biologists, and the NI-I Natural Heritage Bureau.Wildlife locations were obtained from sources including museum specimens, personal contacts, tiie scientific literature, and through extensive field research.For each plant,-animal, and exemplary natural community within a town, we have provided the following information: Name Plants: Readers should remember that common names vary across the range of the plant. For example, "wild lupine" (Zupinus perennis) in New Hampshire is called"wild blue lupine" in New York and "sundial lupine" in other parts of its range; the name also commonly leads to confusion with garden lupine (Lupinuspolyphyllus) which is not native to New Hampshire but grows wild in some areas. Scientific names are standardized with the scientific names used by other Natural Heritage prograins throughout North and South America. The primary refcrcnces-used are: Flora of North Anmerica Editorial 1993-2003. Flora of North America North of Mexico, vols. 1-4, 22, 23,25,26. Oxford University Press, NY.Kartesz, J.T. and I.

Scientific names are standardized with the scientific names used by otherNatural Heritage programs throughout the United States, Canada, the Caribbean, Latin America, and South America.Natural Communities: The names of natural communities reflect the plants that help define them, such as a Beech Forest, or the environmental processes that influence them, such as a Boulder -Cobble River Channel.Listlng Plants: Most of New Hampshire's rare plants are listed as "threatened" or"endangered" under the NH Native Plant Protection Act of 1987 (NH RSA 217-A).The most recent revision of the list came into effect on June 25, 2005. A subset of species are also listed under the federal Endangered Species Act of 1973 (42 USCA-4 4321-4370c). Listing represents apolitical recognition of rarity, so some species that are biologically rare (and therefore included in the list) may not be listed as"threatened" or "endangered." Under the NH Native Plant Protection Act,'endangered" species are those in danger of being extirpated from the state, while"threatened" species face the possibility of becoming "endangered." The presence ofa rare plant or natural community does not limit a landowners ability to use their land -this is stated explicitly in the NH Native Plant Protection Act.Landowners applying for state wetland permits are required by the NH Department of Environmental Services to review options for achieving their land-use objectives while protecting a rare plant or natural community, but projects will not be denied solely on the basis of a rare plant occurrence. In our experience, rare plants are typically destroyed because landowners are not aware of them; minor changes to their projects usually could have saved the rarities. Ourgoal is to help landowners protect rarities on their properties voluntarily. 10 Attachment D: Endangered Species and Historic Places Assessment (Sheet 11 of 16)Known Locations X1i1 Natural Hritag. Bureau Wildlife: A portion ofNew Hampshire's rare animals are listed as "threatened" or"endangered" wider the NH Endangered Species Conservation Act of 1979 (NH- RSA 212-A). A subset of these species are also listed under the federal Endangered Species Act o 1973 (42 USCA na 43214370c). As with plants, listing represents a political recognition ofrarity, so some species that are biologically rare (and therefore included in the list) may not be listed as "threatened" or "endangered." Under the NH Endangered Species Conservation Act, "endangered" species are those in danger of being extirpated from the state, while "threatened" species face the possiility of becoming "endangered." Rare wildlife ib New Hampshire are under thejurisdiction of the Nongame and Endangered Wildlife Program in the N-i Fish & Game Department. We have noted the number of occurrences or a given plant, animal, or natural community within each town. There has not been a comprehensive search of the state for rare species or natural communities, so we arc frequently finding or learning about previouly unknown populations, Further, many rare plant and animal populations have not been checked since they were originally found, sometimes more than 50 years ago, so we do not know the status of these populations. We have listed populations that have not been reported to us in the last 20 years as *historical only"; these populations may still be present, but field surveys are necessary to confirm their survival.We have also included the number of known occurrences of each plant, animal, end natural community within the entire state. Ifino locations are indicated (- -), the species is known to have once occurred in the state; but specific sites are not in our database.When considering the rarity of a species, it is important to consider the status ofa species both in New Hampshire and across its total range. Some spchi=, such as the wildflower Jesup's milk-vtclh (Astragalus robbinsii var.jesupio, are critically imperiled both globally and in New Hampshire. fesup's milk-vetch has three known populations on the planet, all on a 16-mile stretch of the Connecticut River. Other species, such as small yellow lady's-slipper (Cypripedium parvjflorain), are very rare in New Hampshire but quite common in other parts of their range.We refer to a plant species as "globally are" if it has fewer than 20 populations anywhere in the world, or If it has more populations but few reproducing individuals. "State rare" species are those that may be common elsewhere, but have few populations or total individuals in New Hampshire. The rankings for wildlife are based more on the degree of imperilment than on the number of occurrences in the state, although abundance certainly plays a role in assessing a species' long-term viability in New Hampshire. Some species, such as the fish crow (Corms ossffragus) have only a few occurreoces in New Hampshire but, since they are expanding northward into the state, they are considered to be vulnerable but not imperiled. Blanding's turtles (Emydoidea blandingio, on the other hand, appear to be distributed fairly broadly across the state, but populations am small and vulnerable to habitat loss, so they am considered at risk.Flags 11 Attachment D: Endangered Species and Historic Places Assessment (Sheet 12 of 16)NH Natnral Heritage Bureau (The relative quality of a rare species population or natural community is also important when assessing its conservation importance. We consider all populations to be of high conservatiori value, but an "exceleut" population (say with several hundred plants) of a globally rare species is particularly important when compared to a "marginal" population (say with only five plants).To help planners assess the relative importance of rare species and exem'plary natural c6mmunities in their town, we have attached "flags" to occurrences that have been recorded in the last 20 years. The flags are as follows: H" lighest An excellent example of a globally rare species or natural community* Extremely High A good example of a global rarity or an excellent example of a state rarity** Very 1igh A marginal example of a global rarity or a good example of a state rarity* High A marginal example of a state rarity Readers should remember that there are many different ways to assess the value of a rare species population or a natural community. We therefore recommend that towns contact the NH Natural Heritage Bureau at (603) 271-2214 to discuss why occurrences in their towns were flagged at each level Note In addition to recognizing Endangered mid Threatened plant species, the NH Native Plant Protection Act identifies II plants as Special Concern. These species are somewhat uncommon in New Hampshire, and are at risk of decline due to ov"r-collecion, The NH Natural Heritage Bureau does not track these species.Narrow-leaf wild leek A/lium trfrocL-nm var. burdkcki Wild leek A4Itu1a Iricoccum var. tricetccm Wild gingcr A-wrum canadense GChnt blue cohosh Calophyllum giganweum Bla cohosh Caulophyllum Ihalicirrides Sea Limonium carollnianum Ostrich fern Matteuccla strshtopterlt var. pen'vavnica Canadian bumet Sngsuixsrba cuanadtnis Slippery tlm Ulmis rubra If you have any questions or need additional information, please do not hesitate to contact us.

For discharges subject to stormwater effluent limitation guidelines under 40 CFR, Subchapter N, only those stormwater discharges identified in Table 1-I are eligible for coverage under this permit.1.1.4.5 Endangered and Threatened Species and Critical Habitat Protection. Coverage under this permit is available only if your stormwater discharges, allowable non-stormwater discharges, and stormwater discharge-related activities will not adversely affect any species that are federally-listed as endangered or threatened ("listed") under the Endangered Species Act (ESA) and will not result in the adverse modification or destruction of habitat that is federally-designated as "critical habitat" under the ESA.You must meet one of the criteria below, following the procedures in Appendix E: Stormwater Discharges Associated With Industrial Activity 3 Stormwater Discharges Associated With Industrial Activity 3 General Permit Criterion A.Criterion B.No federally-listed threatened or endangered species or their designated critical habitat are likely to occur in the "action area" as defined in Appendix A; or Consultation between a Federal agency and the U.S. Fish and Wildlife Service and/or the National Marine Fisheries Service (together, the "Services") under section 7 of the ESA has been concluded. Consultations can be either formal or informal, and would have occurred only as a result of a separate federal action (e.g., during application for an individual wastewater discharge permit or the issuance of a wetlands dredge and fill permit).The consultation must have addressed the effects of your facility's stormwater discharges, allowable non-stormwater discharges, and stormwater discharge-related activities on federally-listed threatened or endangered species and federally-designated critical habitat, and must have resulted in either: a biological opinion finding no jeopardy to federally-listed species or destruction/adverse modification of federally-designated critical habitat; or ii. written concurrence from the Service(s) with a finding that the facility's stormwater discharges associated with industrial activity, discharge-related activities and allowable non-stormwater discharges are not likely to adversely affect federally-listed species or federally-designated critical habitat; or Criterion C.Criterion D.Criterion E.Your industrial activities are authorized through the issuance of a permit under section 10 of the ESA, and authorization addresses the effects of the stormwater discharges associated with industrial activity, discharge-related' activities, and allowable non-stormwater discharges on federally-listed species and federally-designated critical habitat; or Coordination between you and the U.S. Fish and Wildlife Service and/or the National Marine Fisheries Service has been concluded. The coordination must have addressed the effects of the facility's stormwater discharges associated with industrial activity, discharge-related activities, and allowable non-stormwater discharges on federally-listed threatened or endangered species and federally-designated critical habitat. The result of the coordination must be a written statement from the Service concluding that authorizing your stormwater discharges, discharge-related activities, and allowable non-stormwater discharges is consistent with the determination that the issuance of the MSGP is not likely to adversely affect federally-listed threatened or endangered species and federally-designated critical habitat. Any conditions or prerequisites deemed necessary to achieve consistency with the "not likely to adversely effect" determination become eligibility conditions for MSGP coverage, and permit requirements under Part 2.3; or Authorizing your stormwater discharges associated with industrial activity, discharge-related activities, and allowable non-stormwater discharges is Stormwater Discharges Associated With Industrial Activity 4 Stormwater Discharges Associated With Industrial Activity 4 General Permit consistent with the determination that the issuance of the MSGP is not likely to adversely affect any federally-listed endangered and threatened ("listed") species or designated critical habitat ("critical habitat"). To support your determination that you meet Criterion E, you must provide supporting documentation for your determination.

i. If you are an existing discharger, you must provide the following information with your completed Notice of Intent (NOI) form: (1) a list of the federally-listed threatened or endangered species or their designated critical habitat that are likely to occur in the "action area"; (2) a list of the pollutant parameters for which you have ever exceeded an applicable benchmark or effluent limitations guideline, or for which your discharge has ever been found to cause or contribute to an exceedance of an applicable water quality standard, or to violate State or Tribal water quality requirements (Part 9); and (3) your rationale supporting your determination that you meet Criterion E, including appropriate measures to be undertaken to avoid or eliminate the likelihood of adverse effects.ii. If you are a new discharger, you must provide the following information with your completed NOI form: (1) a list of the federally-listed threatened or endangered species or their designated critical habitat that are likely to occur in the "action area"; (2) a list of the potential pollutants in your discharge; and (3)your rationale supporting your determination that you meet Criterion E, including appropriate measures to be undertaken to avoid or eliminate the likelihood of adverse effects; or Criterion F.The facility's stormwater discharges associated with industrial activity, discharge-related activities, and allowable non-stormwater discharges were already addressed in another operator's valid certification of eligibility that included these discharges and activities and there is no reason to believe that federally-listed species or federally-designated critical habitat not considered in the prior certification may be present or located in the "action area". To certify eligibility under this criterion there must be no lapse of coverage in the other operator's certification.

By certifying eligibility under this criterion, you agree to comply with any measures or controls upon which the other operator's certification was based. You must comply with any applicable terms, conditions, or other requirements developed in the process of meeting the eligibility requirements of the criteria in this section to remain eligible for coverage under this permit. If your certification is based on another operator's certification under Criterion E, that certification is valid only if you have documentation showing that the other operator had certified under Criterion E, and you provide EPA with the supporting information required of existing dischargers in Criterion E (above, under subparagraph (i)) in your NOI form.1.1.4.6 Historic Properties Preservation. Coverage under this permit is available only if your stormwater discharges, allowable non-stormwater discharges, and stormwater discharge-Stormwater Discharges Associated With Industrial Activity 5 General Permit related activities meet one of the eligibility criteria below, following the procedures in Appendix F: Criterion A.Criterion B.Criterion C.Criterion D.Your stormwater discharges and allowable non-stormwater discharges do not have the potential to have an effect on historic properties and you are not constructing or installing new stormwater control measures on your site that cause subsurface disturbance; or Your discharge-related activities (i.e., construction and/or installation of stormwater control measures that involve subsurface disturbance) will not affect historic properties; or Your stormwater discharges, allowable non-stormwater discharges, and discharge-related activities have the potential to have an effect on historic properties, and you have consulted with the State Historic Preservation Officer (SHPO), Tribal Historic Preservation Officer (THPO), or other tribal representative regarding measures to mitigate or prevent any adverse effects on historic properties, and you have either (1) obtained and are in compliance with a written agreement that outlines all such measures, or (2) been unable to reach agreement on such measures; or You have contacted the State Historic Preservation Officer, Tribal Historic Preservation Officer, or other tribal representative and EPA in writing informing them that you have the potential to have an effect on historic properties and you did not receive a response from the SHPO, THPO, or tribal representative within 30 days of receiving your letter.If you have been unable to reach agreement with a SHPO, THPO, or other tribal representative regarding appropriate measures to mitigate or prevent adverse effects, EPA may notify you of additional measures you must implement to be eligible for coverage under this permit.1.1.4. 7New Discharges to Water Quality Impaired Waters. If you are a new discharger you are not eligible for coverage under this permit to discharge to an "impaired water", as defined in Appendix A unless you: a. prevent all exposure to stormwater of the pollutant(s) for which the waterbody is impaired, and retain documentation of procedures taken to prevent exposure onsite with your SWPPP; or b. document that the pollutant(s) for which the waterbody is impaired is not present at your site, and retain documentation of this finding with your SWPPP; or c. in advance of submitting your NOI, provide to the appropriate EPA Regional Office data to support a showing that the discharge is not expecied to cause or contribute to an exceedance of a water quality standard, and retain such data Stormwater Discharges Associated With Industrial Activity 6 General Permit onsite with your SWPPP. To do this, you must provide data and other technical information to the Regional Office sufficient to demonstrate:

i. For discharges to waters without an EPA approved or established TMDL, that the discharge of the pollutant for which the water is impaired will meet in-stream water quality criteria at the point of discharge to the waterbody; or ii. For discharges to waters with an EPA approved or established TMDL, that there are sufficient remaining wasteload allocations in an EPA approved or established TMDL to allow your discharge and that existing dischargers to the waterbody are subject to compliance schedules designed to bring the waterbody into attainment with water quality standards.

You are eligible under Part 1.1.4.7.c if you receive an affirmative determination from the Regional Office that your discharge will not contribute to the existing impairment, in which case you must maintain such determination onsite with your SWPPP, or if the Regional Office fails to respond within 30 days of submission of data to the Regional Office.1.1.4.8 New Discharges to Waters Designated as Tier 3for Antidegradation Purposes. If you are a new discharger, you are not eligible for coverage under this permit for discharges to waters designated by a State or Tribe as Tier 3 (outstanding natural resource waters) for antidegradation purposes under 40 CFR 131.13(a)(3) (see list of Tier 3 waters on EPA's website at http://www.epa.gov/npdes/stormwater/msgp).

1.2 Permit

Compliance. Any noncompliance with any of the requirements of this permit constitutes a violation of the Clean Water Act. As detailed in Part 3 (Corrective Actions) of this permit, failure to take any required corrective actions constitute an independent, additional violation of this permit and the Clean Water Act. As such, any actions and time periods specified for remedying noncompliance do not absolve parties of the initial underlying noncompliance. However, where corrective action is triggered by an event that does not itself constitute permit noncompliance, such as an exceedance of an applicable benchmark, there is no permit violation provided you take the required corrective action within the relevant deadlines established in Part 3.3.1.3 Authorization under this Permit.1.3.1 How to Obtain Authorization.

If you are no longer required to have permit coverage because of a no exposure exclusion and have submitted a No Exposure Certification form to EPA, you are not required to submit a Notice of Termination. You must submit a No Exposure Certification to EPA once every five years. File your No Exposure Certification using the eNOI system at www.epa.,gov/npdes/eNOI.

1.6 Alternative

Permits.1.6.1 EPA Requiring Coverage under an Alternative Permit.EPA may require you to apply for and/or obtain authorization to discharge under either an individual NPDES permit or an alternative NPDES general permit in accordance with 40 CFR 122.64 and 124.5. Any interested person may petition EPA to take action under this paragraph. If EPA requires you to apply for an individual NPDES permit, EPA will notify you in writing that a permit application is required. This notification will include a brief statement of the reasons for this decision and will provide application information. In addition, if you are an existing discharger authorized to discharge under this permit, the notice will set a deadline to file the permit application, and will include a statement that on the effective date of the individual NPDES permit, or the alternative general permit as it applies to you, coverage under this general permit will terminate. EPA may grant additional time to submit the application if you request it.If you are covered under this permit and fail to submit an individual NPDES permit application as required by EPA, then the applicability of this permit to you is terminated at the end of the day specified by EPA as the deadline for application submittal. EPA may take appropriate enforcement action for any unpermitted discharge.

1.6.2 Permittee

Requesting Coverage under an Alternative Permit.You may request to be excluded from coverage under this general permit by applying for an individual permit. In such a case, you must submit an individual permit application in accordance with the requirements of 40 CFR 122.26(c)(1)(ii), with reasons supporting the request, to EPA at the applicable EPA Regional Office listed in Part 7.6.2 of this permit. The request may be granted by issuance of an individual permit or authorization of coverage under an alternative general permit if your reasons are adequate to support the request.When an individual NPDES permit is issued to you or you are authorized to discharge under an alternative NPDES general permit, your authorization to discharge under this permit is terminated on the effective date of the individual permit or the date of authorization of coverage under the alternative general permit.Stormwater Discharges Associated With Industrial Activity I I General Permit 1.7 Severability. Invalidation of a portion of this permit does not necessarily render the whole permit invalid. EPA's intent is that the permit is to remain in effect to the extent possible; in the event that any part of this permit is invalidated, EPA will advise the regulated community as to the effect of such invalidation.

2. Control Measures and Effluent Limits.In the technology-based limits included in Part 2.1 and in Part 8, the term "minimize" means reduce and/or eliminate to the extent achievable using control measures (including best management practices) that are technologically available and economically practicable and achievable in light of best industry practice.2.1 Control Measures.You must select, design, install, and implement control measures (including best management practices) to address the selection and design considerations in Part 2.1.1, meet the non-numeric effluent limits in Part 2.1.2, and meet limits contained in applicable effluent limitations guidelines in Part 2.1.3. The selection, design, installation, and implementation of these control measures must be in accordance with good engineering practices and manufacturer's specifications.

Note that you may deviate from such manufacturer's specifications where you provide justification for such deviation and include documentation of your rationale in the part of your SWPPP that describes your control measures, consistent with Part 5.1.4. If you find that your control measures are not achieving their intended effect of minimizing pollutant discharges, you must modify these control measures as expeditiously as practicable. Regulated stormwater discharges from your facility include stormwater run-on that commingles with stormwater discharges associated with industrial activity at your facility.2.1.1 Control Measure Selection and Design Considerations You must consider the following when selecting and designing control measures:* preventing stormwater from coming into contact with polluting materials is generally more effective, and less costly, than trying to remove pollutants from stormwater; o using control measures in combination is more effective than using control measures in isolation for minimizing pollutants in your stormwater discharge; o assessing the type and quantity of pollutants, including their potential to impact receiving water quality, is critical to designing effective control measures that will achieve the limits in this permit;* minimizing impervious areas at your facility and infiltrating runoff onsite (including bioretention cells, green roofs, and pervious pavement, among other approaches) can reduce runoff and improve groundwater recharge and stream base flows in local streams, although care must be taken to avoid ground water contamination; Stormwater Discharges Associated With Industrial Activity 12 General Permit" attenuating flow using open vegetated swales and natural depressions can reduce in-stream impacts of erosive flows;* conserving and/or restoring of riparian buffers will help protect streams from stormwater runoff and improve water quality; and" using treatment interceptors (e.g., swirl separators and sand filters) may be appropriate in some instances to minimize the discharge of pollutants. 2.1.2 Non-Numeric Technology-Based Effluent Limits (BPT/BAT/BCT). 2.1.2.1 Minimize Exposure. You must minimize the exposure of manufacturing, processing, and material storage areas (including loading and unloading, storage, disposal, cleaning, maintenance, and fueling operations) to rain, snow, snowmelt, and runoff by either locating these industrial materials and activities inside or protecting them with storm resistant coverings (although significant enlargement of impervious surface area is not recommended). In minimizing exposure, you should pay particular attention to the following: -use grading, berming, or curbing to prevent runoff of contaminated flows and divert run-on away from these areas;-locate materials, equipment, and activities so that leaks are contained in existing containment and diversion systems (confine the storage of leaky or leak-prone vehicles and equipment awaiting maintenance to protected areas);-clean up spills and leaks promptly using dry methods (e.g., absorbents) to prevent the discharge of pollutants; -use drip pans and absorbents under or around leaky vehicles and equipment or store indoors where feasible;-use spill/overflow protection equipment; -drain fluids from equipment and vehicles prior to on-site storage or disposal;-perform all cleaning operations indoors, under cover, or in bermed areas that prevent runoff and run-on and also that capture any overspray; and-ensure that all washwater drains to a proper collection system (i.e., not the stormwater drainage system).The discharge of vehicle and equipment washwater, including tank cleaning operations, is not authorized by this permit. These wastewaters must be covered under a separate NPDES permit, discharged to a sanitary sewer in accordance with applicable industrial pretreatment requirements, or disposed of otherwise in accordance with applicable law.Note: Industrial materials do not need to be enclosed or covered if stormwater runoff from affected areas will not be discharged to receiving waters or if discharges are authorized under another NPDES permit.2.1.2.2 Good Housekeeping. You must keep clean all exposed areas that are potential sources of pollutants, using such measures as sweeping at regular intervals, keeping materials orderly and labeled, and storing materials in appropriate containers. Stormwater Discharges Associated With Industrial Activity 13 General Permit 2.1.2.3 Maintenance. You must regularly inspect, test, maintain, and repair all industrial equipment and systems to avoid situations that may result in leaks, spills, and other releases of pollutants in stormwater discharged to receiving waters. You must maintain all control measures that are used to achieve the effluent limits required by this permit in effective operating condition. Nonstructural control measures must also be diligently maintained (e.g., spill response supplies available, personnel appropriately trained). If you find that your control measures need to be replaced or repaired, you must make the necessary repairs or modifications as expeditiously as practicable. 2.1.2.4 Spill Prevention and Response Procedures. You must minimize the potential for leaks, spills and other releases that may be exposed to stormwater and develop plans for effective response to such spills if or when they occur. At a minimum, you must implement:

• Procedures for plainly labeling containers (e.g., "Used Oil," "Spent Solvents,""Fertilizers and Pesticides," etc.) that could be susceptible to spillage or leakage to encourage proper handling and facilitate rapid response if spills or leaks occur;* Preventative measures such as barriers between material storage and traffic areas, secondary containment provisions, and procedures for material storage and handling;" Procedures for expeditiously stopping, containing, and cleaning up leaks, spills, and other releases.

Employees who may cause, detect, or respond to a spill or leak must be trained in these procedures and have necessary spill response equipment available. If possible, one of these individuals should be a member of your stormwater pollution prevention team (see Part 5.1.1); and o Procedures for notification of appropriate facility personnel, emergency response agencies, and regulatory agencies.

2.2 Water

Quality-Based Effluent Limitations.

2.2.1 Water

Quality Standards Your discharge must be controlled as necessary to meet applicable water quality standards. EPA expects that compliance with the other conditions in this permit will control discharges as necessary to meet applicable water quality standards. If at any time you become aware, or EPA determines, that your discharge causes or contributes to an exceedance of applicable water quality standards, you must take corrective action as required in Part 3.1, document the corrective actions as required in Parts 3.4 and 5.4, and report the corrective actions to EPA as required in Part 7.2.Stormwater Discharges Associated With Industrial Activity 16 General Permit Additionally, EPA may impose additional water quality-based limitations on a site-specific basis, or require you to obtain coverage under an individual permit, if information in your NOI, required reports, or from other sources indicates that your discharges are not controlled as necessary to meet applicable water quality standards.

2.2.2 Discharges

to Water Quality Impaired Waters.2.2.2.1 Existing Discharge to an Impaired Water with an EPA Approved or Established TMDL. If you discharge to an impaired water with an EPA approved or established TMDL, EPA will inform you if any additional limits or controls are necessary for your discharge to be consistent with the assumptions of any available wasteload allocation in the TMDL, or if coverage under an individual permit is necessary in accordance with Part 1.6.1.2.2.2.2 Existing Discharge to an Impaired Water without an EPA Approved or Established TMDL. If you discharge to an impaired water without an EPA approved or established TMDL, you are required to comply with Part 2.2.1 and the monitoring requirement of Part 6.2.4. Note that this provision also applies to situations where EPA determines that your discharge is not controlled as necessary to meet water quality standards in a downstream water segment, even if your discharge is to a receiving water that is not specifically identified on a Section 303(d) list.2.2.2.3 New Discharge to an Impaired Water. If your authorization to discharge under this permit relied on Part 1.1.4.7 for a new discharge to an impaired water, you must implement and maintain any control measures or conditions on your site that enabled you to become eligible under Part 1.1.4.7, and modify such measures or conditions as necessary pursuant to any Part 3 corrective actions. You are also required to comply with Part 2.2.1 and the monitoring requirements of Parts 6.2.4.2.2.3 Tier 2 Antidegradation Requirements for New or Increased Dischargers If you are a new discharger, or an existing discharger required to notify EPA of an increased discharge consistent with Part 7.4 (i.e., a "planned changes" report), and you discharge directly to waters designated by a State or Tribe as Tier 2 or Tier 2.5 for antidegradation purposes under 40 CFR 131.12(a) (see list of Tier 2 and 2.5 waters on EPA's website at http://www.epa.gov/npdes/stormwater/msgp), EPA may notify you that additional analyses, control measures, or other permit conditions are necessary to comply with the applicable antidegradation requirements, or notify you that an individual permit application is necessary in accordance with Part 1.6.1.2.3 Requirements Relating to Endangered Species and Historic Properties If your eligibility under either Part 1. 1.4.5 or Part 1.1.4.6 was made possible through your, or another operator's, agreement to include certain measures or prerequisite actions, or implement certain terms and conditions, you must comply with all such agreed-upon requirements to maintain eligibility under the MSGP.Stormwater Discharges Associated With Industrial Activity 17 General Permit 2.4 Requirements Relating to the National Environmental Policy Act (NEPA) Review If your eligibility under Part 1.1.2.5 was made possible through your agreement to implement any mitigation measures as a result of the NEPA review process, you must comply with all such agreed-upon measures to maintain eligibility under the MSGP.3. Corrective Actions 3.1 Conditions Requiring Review and Revision to Eliminate Problem If any of the following conditions occur, you must review and revise the selection, design, installation, and implementation of your control measures to ensure that the condition is eliminated and will not be repeated in the future: " an unauthorized release or discharge (e.g., spill, leak, or discharge of non-stormwater not authorized by this or another NPDES permit) occurs at your facility;o a discharge violates a numeric effluent limit;o you become aware, or EPA determines, that your control measures are not stringent enough for the discharge to meet applicable water quality standards; o an inspection or evaluation of your facility by an EPA official, or local, State, or Tribal entity, determines that modifications to the control measures are necessary to meet the non-numeric effluent limits in this permit; or o you find in your routine facility inspection, quarterly visual assessment, or comprehensive site inspection that your control measures are not being properly operated and maintained.

3.2 Conditions

Requiring Review to Determine if Modifications Are Necessary If any of the following conditions occur, you must review the selection, design, installation, and implementation of your control measures to determine if modifications are necessary to meet the effluent limits in this permit: o construction or a change in design, operation, or maintenance at your facility significantly changes the nature of pollutants discharged in stormwater from your facility, or significantly increases the quantity of pollutants discharged; or o the average of 4 quarterly sampling results exceeds an applicable benchmark. If less than 4 benchmark samples have been taken, but the results are such that an exceedence of the 4 quarter average is mathematically certain (i.e., if the sum of quarterly sample results to date is more than 4 times the benchmark level) this is considered a benchmark exceedence, triggering this review.3.3 Corrective Action Deadlines You must document your discovery of any of the conditions listed in Parts 3.1 and 3.2 within 24 hours of making such discovery. Subsequently, within 14 days of such discovery, you Stormwater Discharges Associated With Industrial Activity 18 General Permit must document any corrective action(s) to be taken to eliminate or further investigate the deficiency, or if no corrective action is needed, the basis for that determination. Specific documentation required within 24 hours and 14 days is detailed in Part 3.4. If you determine that changes are necessary following your review, any modifications to your control measures must be made before the next storm event if possible, or as soon as practicable following that storm event. These time intervals are not grace periods, but are schedules considered reasonable for documenting your findings and for making repairs and improvements. They are included in this permit to ensure that the conditions prompting the need for these repairs and improvements are not allowed to persist indefinitely.

3.4 Corrective

Action Report Within 24 hours of discovery of any condition listed in Parts 3.1 and 3.2, you must document the following information (i.e., questions 3-5 of the Corrective Actions section in the Annual Reporting Form, provided in Appendix I): " Identification of the condition triggering the need for corrective action review;o Description of the problem identified; and" Date the problem was identified. Within 14 days of discovery of any condition listed in Parts 3.1 and 3.2, you must document the following information (i.e., questions 7-11 of the Corrective Actions section in the Annual Reporting Form, provided in Appendix I): o Summary of corrective action taken or to be taken (or, for triggering events identified in Part 3.2 where you determine that corrective action is not necessary, the basis for this determination); o Notice of whether SWPPP modifications are required as a result of this discovery or corrective action;o Date corrective action initiated; and o Date corrective action completed or expected to be completed. You must submit this documentation in an annual report as required in Part 7.2 and retain a copy onsite with your SWPPP as required in Part 5.4.3.5 Effect of Corrective Action If the event triggering the review is a permit violation (e.g., non-compliance with an effluent limit), correcting it does not remove the original violation. Additionally, failing to take corrective action in accordance with this section is an additional permit violation. EPA will consider the appropriateness and promptness of corrective action in determining enforcement responses to permit violations. Stormwater Discharges Associated With Industrial Activity 19 Stormwater Discharges Associated With Industrial Activity 19 General Permit 3.6 Substantially Identical Outfalls If the event triggering corrective action is linked to an outfall that represents other substantially identical outfalls, your review must assess the need for corrective action for each outfall represented by the outfall that triggered the review. Any necessary changes to control measures that affect these other outfalls must also be made before the next storm event if possible, or as soon as practicable following that storm event.4. Inspections You must conduct the inspections in Parts 4.1, 4.2, and 4.3 at your facility.4.1 Routine Facility Inspections.

4.1.1 Routine

Inactive and Unstaffed Sites: The requirement to conduct routine facility inspections on a quarterly basis does not apply at a facility that is inactive and unstaffed, as long as there are no industrial materials or activities exposed to stormwater. Such a facility is only required to conduct an annual comprehensive site inspection in accordance with the requirements of Part 4.3. To invoke this exception, you must maintain a statement in your SWPPP pursuant to Part 5.1.5.2 indicating that the site is inactive and unstaffed, and that there are no industrial materials or activities exposed to precipitation, in accordance with the substantive requirements in 40 CFR 122.26(g)(4)(iii). The statement must be signed and certified in accordance with Appendix B, Subsection

11. If circumstances change and industrial materials or activities become exposed to stormwater or your facility becomes active and/or staffed, this exception no longer applies and you must immediately resume quarterly facility inspections.

If you are not qualified for this exception at the time you are authorized under this permit, but during the permit term you become qualified because your facility is inactive and unstaffed, and there are no industrial materials or activities that are exposed to stormwater, then you must include the same signed and certified statement as above and retain it with your records pursuant to Part 5.4.Inactive and unstaffed facilities covered under Sectors G (Metal Mining), H (Coal Mines and Coal Mining-Related Facilities), and J (Non-Metallic Mineral Mining and Dressing), are not required to meet the "no industrial materials or activities exposed to stormwater" standard to be eligible for this exception from routine inspections, consistent with the requirements established in Parts 8.G.8.4, 8.H.8.1, and 8.J.8.1.4.2 Quarterly Visual Assessment of Stormwater Discharges.

4.2.1 Quarterly

Visual Assessment Procedures. Once each quarter for the entire permit term, you must collect a stormwater sample from each outfall (except as noted in Part 4.2.3) and conduct a visual assessment of each of these samples. These samples are not required to be collected consistent with 40 CFR Part 136 procedures but should be collected in such a manner that the samples are representative of the stormwater discharge. The visual assessment must be made: " Of a sample in a clean, clear glass, or plastic container, and examined in a well-lit area;" On samples collected within the first 30 minutes of an actual discharge from a storm event. If it is not possible to collect the sample within the first 30 minutes of discharge, the sample must be collected as soon as practicable after the first 30 Stormwater Discharges Associated With Industrial Activity 21 General Permit minutes and you must document why it was not possible to take samples within the first 30 minutes. In the case of snowmelt, samples must be taken during a period with a measurable discharge from your site; and For storm events, on discharges that occur at least 72 hours (3 days) from the previous discharge. The 72-hour (3-day) storm interval does not apply if you document that less than a 72-hour (3-day) interval is representative for local storm events during the sampling period.You must visually inspect the sample for the following water quality characteristics: Color;Odor;Clarity;Floating solids;Settled solids;Suspended solids;Foam;Oil sheen; and Other obvious indicators of stormwater pollution.

4.2.2 Quarterly

Visual Assessment Documentation. You must document the results of your visual assessments and maintain this documentation onsite with your SWPPP as required in Part 5.4. You are not required to submit your visual assessment findings to EPA, unless specifically requested to do so. At a minimum, your documentation of the visual assessment must include:* Sample location(s)

• Sample collection date and time, and visual assessment date and time for each sample;* Personnel collecting the sample and performing visual assessment, and their signatures; o Nature of the discharge (i.e., runoff or snowmelt);" Results of observations of the stormwater discharge; o Probable sources of any observed stormwater contamination,* If applicable, why it was not possible to take samples within the first 30 minutes.Any corrective action required as a result of a quarterly visual assessment must be performed consistent with Part 3 of this permit.4.2.3 Exceptions to Quarterly Visual Assessments.

Adverse Weather Conditions: When adverse weather conditions prevent the collection of samples during the quarter, you must take a substitute sample during the next qualifying storm event. Documentation of the rationale for no visual assessment for the quarter must be included with your SWPPP records as described in Part 5.4. Adverse conditions are Stormwater Discharges Associated With Industrial Activity 22 General Permit those that are dangerous or create inaccessibility for personnel, such as local flooding, high winds, or electrical storms, or situations that otherwise make sampling impractical, such as drought or extended frozen conditions. Climates with Irregular Stormwater Runofi: If your facility is located in an area where limited rainfall occurs during many parts of the year (e.g., arid or semi-arid climate) or in an area where freezing conditions exist that prevent runoff from occurring for extended periods, then your samples for the quarterly visual assessments may be distributed during seasons when precipitation runoff occurs.Areas Subiect to Snow: In areas subject to snow, at least one quarterly visual assessment must capture snowmelt discharge, as described in Part 6.1.3, taking into account the exception described above for climates with irregular stormwater runoff.Inactive and unstaffed sites: The requirement for a quarterly visual assessment does not apply at a facility that is inactive and unstaffed, as long as there are no industrial materials or activities exposed to stormwater. To invoke this exception, you must maintain a statement in your SWPPP as required in Part 5.1.5.2 indicating that the site is inactive and unstaffed, and that there are no industrial materials or activities exposed to precipitation, in accordance with the substantive requirements in 40 CFR 122.26(g)(4)(iii). The statement must be signed and certified in accordance with Appendix B, Subsection

11. If circumstances change and industrial materials or activities become exposed to stormwater or your facility becomes active and/or staffed, this exception no longer applies and you must immediately resume quarterly visual assessments.

If you are not qualified for this exception at the time you are authorized under this permit, but during the permit term you become qualified because your facility is inactive and unstaffed, and there are no industrial materials or activities that are exposed to stormwater, then you must include the same signed and certified statement as above and retain it with your records pursuant to Part 5.4.Inactive and unstaffed facilities covered under Sectors G (Metal Mining), H (Coal Mines and Coal Mining-Related Facilities), and J (Non-Metallic Mineral Mining and Dressing), are not required to meet the "no industrial materials or activities exposed to stormwater" standard to be eligible for this exception from quarterly visual assessment, consistent with the requirements established in Parts 8.G.8.4, 8.H.8.1, and 8.J.8.1.Substantially identical outfalls: If your facility has two or more outfalls that you believe discharge substantially identical effluents, as documented in Part 5.1.5.2, you may conduct quarterly visual assessments of the discharge at just one of the outfalls and report that the results also apply to the substantially identical outfall(s) provided that you perform visual assessments on a rotating basis of each substantially identical outfall throughout the period of your coverage under this permit.If stormwater contamination is identified through visual assessment performed at a substantially identical outfall, you must assess and modify your control measures as appropriate for each outfall represented by the monitored outfall.Stormwater Discharges Associated With Industrial Activity 23 General Permit 4.3 Comprehensive Site Inspections.

6.1 Monitoring

Procedures

6.1.1 Monitored

Outfalls.Applicable monitoring requirements apply to each outfall authorized by this permit, except as otherwise exempt from monitoring as a "substantially identical outfall." If your facility has two or more outfalls that you believe discharge substantially identical effluents, based on the similarities of the general industrial activities and control measures, exposed materials that may significantly contribute pollutants to stormwater, and runoff coefficients of their drainage areas, you may monitor the effluent ofjust one of the outfalls and report that the results also apply to the substantially identical outfall(s). As required in Part 5.1.5.2, your SWPPP must identify each outfall authorized by this permit and describe the rationale for any substantially identical outfall determinations. The allowance for monitoring only one of the substantially identical outfalls is not applicable to any outfalls with numeric effluent limitations. You are required to monitor each outfall covered by a numeric effluent limit as identified in Part 6.2.2.6.1.2 Commingled Discharges. If discharges authorized by this permit commingle with discharges not authorized under this permit, any required sampling of the authorized discharges must be performed at a point before they mix with other waste streams, to the extent practicable.

6.1.3 Measurable

Storm Events.All required monitoring must be performed on a storm event that results in an actual discharge from your site ("measurable storm event") that follows the preceding measurable storm event by at least 72 hours (3 days). The 72-hour (3-day) storm interval does not apply if you are able to document that less than a 72-hour (3-day) interval is representative for local storm events during the sampling period. In the case of snowmelt, the monitoring must be performed at a time when a measurable discharge occurs at your site.For each monitoring event, except snowmelt monitoring, you must identify the date and duration (in hours) of the rainfall event, rainfall total (in inches) for that rainfall event, and time (in days) since the previous measurable storm event. For snowmelt monitoring, you must identify the date of the sampling event.Stormwater Discharges Associated With Industrial Activity 33 Stormwater Discharges Associated With Industrial Activity 33 General Permit 6.1.4 Sample Type.You must take a minimum of one grab sample from a discharge resulting from a measurable storm event as described in Part 6.1.3. Samples must be collected within the first 30 minutes of a measurable storm event. If it is not possible to collect the sample within the first 30 minutes of a measurable storm event, the sample must be collected as soon as practicable after the first 30 minutes and documentation must be kept with the SWPPP explaining why it was not possible to take samples within the first 30 minutes. In the case of snowmelt, samples must be taken during a period with a measurable discharge.

6.1.5 Adverse

Weather Conditions. When adverse weather conditions as described in Part 4.2.3 prevent the collection of samples according to the relevant monitoring schedule, you must take a substitute sample during the next qualifying storm event. Adverse weather does not exempt you from having to file a benchmark monitoring report in accordance with your sampling schedule. You must report any failure to monitor as specified in Part 7.1 indicating the basis for not sampling during the usual reporting period.6.1.6 Climates with Irregular Stormwater Runoff.If your facility is located in areas where limited rainfall occurs during parts of the year (e.g., arid or semi-arid climates) or in areas where freezing conditions exist that prevent runoff from occurring for extended periods, required monitoring events may be distributed during seasons when precipitation occurs, or when snowmelt results in a measurable discharge from your site. You must still collect the required number of samples.6.1.7 Monitoring Periods.Monitoring requirements in this permit begin in the first full quarter following either April 1, 2009 or your date of discharge authorization, whichever date comes later. If your monitoring is required on a quarterly basis (e.g., benchmark monitoring), you must monitor at least once in each of the following 3-month intervals: o January 1 -March 31;o April 1 -June 30;* July 1 -September 30; and a October 1 -December 31.For example, if you obtain permit coverage on June 2, 2009, then your first monitoring quarter is July 1 -September 30, 2009. This monitoring schedule may be modified in accordance with Part 6.1.6 if the revised schedule is documented with your SWPPP and provided to EPA with your first monitoring report.Stormwater Discharges Associated With Industrial Activity 34 General Permit 6.1.8 Monitoring for Allowable Non-Stormwater Discharges You are only required to monitor allowable non-stormwater discharges (as delineated in Part 1.1.3) when they are commingled with stormwater discharges associated with industrial activity.6.2 Required Monitoring. This permit includes five types of required analytical monitoring, one or more of which may apply to your discharge: " Quarterly benchmark monitoring (see Part 6.2.1)* Annual effluent limitations guidelines monitoring (see Part 6.2.2);" State- or Tribal-specific monitoring (see Part 6.2.3);o Impaired waters monitoring (see Part 6.2.4); and" Other monitoring as required by EPA (see Part 6.2.5).When more than one type of monitoring for the same parameter at the same outfall applies (e.g., total suspended solids once per year for an effluent limit and once per quarter for benchmark monitoring at a given outfall), you may use a single sample to satisfy both monitoring requirements (i.e., one sample satisfying both the annual effluent limit sample and one of the 4 quarterly benchmark monitoring samples).All required monitoring must be conducted in accordance with the procedures described in Appendix B, Subsection IO.D.6.2.1 Benchmark Monitoring. This permit stipulates pollutant benchmark concentrations that may be applicable to your discharge. The benchmark concentrations are not effluent limitations; a benchmark exceedance, therefore, is not a permit violation. Benchmark monitoring data are primarily for your use to determine the overall effectiveness of your control measures and to assist you in knowing when additional corrective action(s) may be necessary to comply with the effluent limitations in Part 2.6.2.1.1 Applicability of Benchmark Monitoring. You must monitor for any benchmark parameters specified for the industrial sector(s), both primary industrial activity and any co-located industrial activities, applicable to your discharge. Your industry-specific benchmark concentrations are listed in the sector-specific sections of Part 8. If your facility is in one of the industrial sectors subject to benchmark concentrations that are hardness-dependent, you are required to submit to EPA with your first benchmark report a hardness value, established consistent with the procedures in Appendix J, which is representative of your receiving water.Samples must be analyzed consistent with 40 CFR Part 136 analytical methods and using test procedures with quantitation limits at or below benchmark values for all benchmark parameters for which you are required to sample.Stormwater Discharges Associated With Industrial Activity 35 General Permit 6.2.1.2 Benchmark Monitoring Schedule. Benchmark monitoring must be conducted quarterly, as identified in Part 6.1.7, for your first 4 full quarters of permit coverage commencing no earlier than April 1, 2009. Facilities in climates with irregular stormwater runoff, as described in Part 6.1.6, may modify this quarterly schedule provided that this revised schedule is reported to EPA when the first benchmark sample is collected and reported, and that this revised schedule is kept with the facility's SWPPP as specified in Part 5.4.Data not exceeding benchmarks: After collection of 4 quarterly samples, if the average of the 4 monitoring values for any parameter does not exceed the benchmark, you have fulfilled your monitoring requirements for that parameter for the permit term. For averaging purposes, use a value of zero for any individual sample parameter, analyzed using procedures consistent with Part 6.2.1.1, which is determined to be less than the method detection limit. For sample values that fall between the method detection level and the quantitation limit (i.e., a confirmed detection but below the level that can be reliably quantified), use a value halfway between zero and the quantitation limit.Data exceeding benchmarks: After collection of 4 quarterly samples, if the average of the 4 monitoring values for any parameter exceeds the benchmark, you must, in accordance with Part 3.2, review the selection, design, installation, and implementation of your control measures to determine if modifications are necessary to meet the effluent limits in this permit, and either:* Make the necessary modifications and continue quarterly monitoring until you have completed 4 additional quarters of monitoring for which the average does not exceed the benchmark; or* Make a determination that no further pollutant reductions are technologically available and economically practicable and achievable in light of best industry practice to meet the technology-based effluent limits or are necessary to meet the water-quality-based effluent limitations in Parts 2 of this permit, in which case you must continue monitoring once per year. You must also document your rationale for concluding that no further pollutant reductions are achievable, and retain all records related to this documentation with your SWPPP. You must also notify EPA of this determination in your next benchmark monitoring report.In accordance with Part 3.2, you must review your control measures and perform any required corrective action immediately (or document why no corrective action is required), without waiting for the full 4 quarters of monitoring data, if an exceedance of the 4 quarter average is mathematically certain. If after modifying your control measures and conducting 4 additional quarters of monitoring, your average still exceeds the benchmark (or if an exceedance of the benchmark by the 4 quarter average is mathematically certain prior to conducting the full 4 additional quarters of monitoring), you must again review your control measures and take one of the two actions above.Stormwater Discharges Associated With Industrial Activity 36 General Permit Natural background pollutant levels: Following the first 4 quarters of benchmark monitoring (or sooner if the exceedance is triggered by less than 4 quarters of data, see above), if the average concentration of a pollutant exceeds a benchmark value, and you determine that exceedance of the benchmark is attributable solely to the presence of that pollutant in the natural background, you are not required to perform corrective action or additional benchmark monitoring provided that: " The average concentration of your benchmark monitoring results is less than or equal to the concentration of that pollutant in the natural background; o You document and maintain with your SWPPP, as required in Part 5.4, your supporting rationale for concluding that benchmark exceedances are in fact attributable solely to natural background pollutant levels. You must include in your supporting rationale any data previously collected by you or others (including literature studies) that describe the levels of natural background pollutants in your stormwater discharge; and o You notify EPA on your final quarterly benchmark monitoring report that the benchmark exceedances are attributable solely to natural background pollutant levels.Natural background pollutants include those substances that are naturally occurring in soils or groundwater. Natural background pollutants do not include legacy pollutants from earlier activity on your site, or pollutants in run-on from neighboring sources which are not naturally occurring. 6.2.1.3 Exception for Inactive and Unstaffed Sites. The requirement for benchmark monitoring does not apply at a facility that is inactive and unstaffed, as long as there are no industrial materials or activities exposed to stormwater. To invoke this exception, you must do the following: " Maintain a statement onsite with your SWPPP stating that the site is inactive and unstaffed, and that there are no industrial materials or activities exposed to stormwater in accordance with the substantive requirements in 40 CFR 122.26(g)and sign and certify the statement in accordance with Appendix B, Subsection 11;and o If circumstances change and industrial materials or activities become exposed to stormwater or your facility becomes active and/or staffed, this exception no longer applies and you must immediately begin complying with the applicable benchmark monitoring requirements under Part 6.2 as if you were in your first year of permit coverage. You must indicate in your first benchmark monitoring report that your facility has materials or activities exposed to stormwater or has become active and/or staffed.o If you are not qualified for this exception at the time you are authorized under this permit, but during the permit term you become qualified because your facility is inactive and unstaffed, and there are no industrial materials or activities that are exposed to stormwater, then you must notify EPA of this change in your next benchmark monitoring report. You may discontinue benchmark monitoring once Stormwater Discharges Associated With Industrial Activity 37 General Permit you have notified EPA, and prepared and signed the certification statement described above concerning your facility's qualification for this special exception. Note: This exception has different requirements for Sectors G, H, and J (see Part 8).6.2.2 Effluent Limitations Monitoring. 6.2.2.1 Monitoring Based on Effluent Limitations Guidelines. Table 6-1 identifies the stormwater discharges subject to effluent limitation guidelines that are authorized for coverage under this permit. Beginning in the first full quarter following April 1, 2009 or your date of discharge authorization, whichever date comes later, you must monitor once per year at each outfall containing the discharges identified in Table 6-1 for the parameters specified in the sector-specific section of Part 8.Table 6-1. Required Monitoring for Effluent Limits Based on Effluent Limitations Guidelines Regulated Activity Effluent Limit Monitoring Sample Frequency Type Discharges resulting from spray down or intentional See Part 8.A.7 1/year Grab wetting of logs at wet deck storage areas Runoff from phosphate fertilizer manufacturing See Part 8.C.4 1/year Grab facilities that comes into contact with any raw materials, finished product, by-products or waste products (SIC 2874)Runoff from asphalt emulsion facilities See Part 8.D.4 1/year Grab Runoff from material storage piles at cement See Part 8.E.5 1/year Grab manufacturing facilities Mine dewatering discharges at crushed stone, See Part 8.J.9 1/year Grab construction sand and gravel, or industrial sand mining facilities Runoff from hazardous waste landfills See Part 8.K.6 1/year Grab Runoff from non-hazardous waste landfills See Part 8.L.10 1/year Grab Runoff from coal storage piles at steam electric See Part 8.0.8 1/year generating facilities 6.2.2.2 Substantially Identical Outfalls. You must monitor each outfall discharging runoff from any regulated activity identified in Table 6-1. The substantially identical outfall monitoring provisions are not available for numeric effluent limits monitoring.

6.2.3 State

or Tribal Provisions Monitoring 6.2.3.1 Sectors Required to Conduct State or Tribal Monitoring. You must comply with any State or Tribal monitoring requirements (see Part 9) applicable to your facility's location.6.2.3.2 State or Tribal Monitoring Schedule. If a monitoring frequency is not specified for an applicable requirement in Part 9, you must monitor once per year for the entire permit term.Stormwater Discharges Associated With Industrial Activity 38 General Permit 6.2.4 Discharges to Impaired Waters Monitoring. 6.2.4.1 Permittees Required to Monitor Discharges to Impaired Waters. If you discharge to an impaired water, you must monitor for all pollutants for which the waterbody is impaired and for which a standard analytical method exists (see 40 CFR Part 136).If the pollutant for which the waterbody is impaired is suspended solids, turbidity or sediment/sedimentation, you must monitor for Total Suspended Solids (TSS). If the pollutant for which the waterbody is impaired is expressed in the form of an indicator or surrogate pollutant, you must monitor for that indicator or surrogate pollutant. No monitoring is required when a waterbody's biological communities are impaired but no pollutant, including indicator or surrogate pollutants, is specified as causing the impairment, or when a waterbody's impairment is related to hydrologic modifications, impaired hydrology, or temperature. 6.2.4.2 Impaired Waters Monitoring Schedule.Discharges to impaired waters without an EPA approved or established TMDL: Beginning in the first full quarter following April 1, 2009 or your date of discharge authorization, whichever date comes later, you must monitor once per year at each outfall (except substantially identical outfalls) discharging stormwater to impaired waters without an EPA approved or established TMDL. This monitoring requirement does not apply after one year if the pollutant for which the waterbody is impaired is not detected above natural background levels in your stormwater discharge, and you document, as required in Part 5.4 (Additional Documentation Requirements), that this pollutant is not expected to be present above natural background levels in your discharge. If the pollutant for which the water is impaired is not present and not expected to be present in your discharge, or it is present but you have determined that its presence is caused solely by natural background sources, you should include a notification to this effect in your first monitoring report, after which you may discontinue annual monitoring. To support a determination that the pollutant's presence is caused solely by natural background sources, you must keep the following documentation with your SWPPP records: o An explanation of why you believe that the presence of the pollutant causing the impairment in your discharge is not related to the activities at your facility; and" Data and/or studies that tie the presence of the pollutant causing the impairment in your discharge to natural background sources in the watershed. Natural background pollutants include those substances that are naturally occurring in soils or groundwater. Natural background pollutants do not include legacy pollutants from earlier activity on your site, or pollutants in run-on from neighboring sources which are not naturally occurring. Stormwater Discharges Associated With Industrial Activity 39 Stormwater Discharges Associated With Industrial Activity 39 General Permit Discharg-es to impaired waters with an EPA approved or established TMDL: For stormwater discharges to waters for which there is an EPA approved or established TMDL, you are not required to monitor for the pollutant for which the TMDL was written unless EPA informs you, upon examination of the applicable TMDL and/or WLA, that you are subject to such a requirement consistent with the assumptions of the applicable TMDL and/or WLA. EPA's notice will include specifications on which pollutant to monitor and the required monitoring frequency during the first year of permit coverage. Following the first year of monitoring: 0 If the TMDL pollutant is not detected in any of your first year samples, you may discontinue further sampling, unless the TMDL has specific instructions to the contrary, in which case you must follow those instructions. You must keep records of this finding onsite with your SWPPP.* If you detect the presence of the pollutant causing the impairment in your stormwater discharge for any of the samples collected in your first year, you must continue monitoring annually throughout the term of this permit, unless the TMDL specifies more frequent monitoring, in which case you must follow the TMDL requirements.

6.2.5 Additional

Monitoring Required by EPA.EPA may notify you of additional discharge monitoring requirements. Any such notice will briefly state the reasons for the monitoring, locations, and parameters to be monitored, frequency and period of monitoring, sample types, and reporting requirements. 6.3 Follow-up Actions if Discharge Exceeds Numeric Effluent Limit.You must conduct follow-up monitoring within 30 calendar days (or during the next qualifying runoff event, should none occur within 30 days) of implementing corrective action(s)taken pursuant to Part 3 in response to an exceedance of a numeric effluent limit contained in this permit. See Part 9 for specific monitoring requirements applicable to individual States or Tribes. Monitoring must be performed for any pollutant(s) that exceeds the effluent limit. If this follow-up monitoring exceeds the applicable effluent limitation, you must comply with both Parts 6.3.1 and 6.3.2.6.3.1 Submit an Exceedance Report.You must submit an Exceedance Report consistent with Part 7.3.6.3.2 Continue to Monitor.You must continue to monitor, at least quarterly, until your discharge is in compliance with the effluent limit or until EPA waives the requirement for additional monitoring.

Only the stormwater discharges from the following areas are covered: waste rock and overburden piles if composed entirely of stormwater and not combining with mine drainage; topsoil piles; offsite haul and access roads; onsite haul and access roads constructed of waste rock, overburden, or spent ore if composed entirely of stormwater and not combining with mine drainage; onsite haul and access roads not constructed of waste rock, overburden, or spent ore except if mine drainage is used for dust control; runoff from tailings dams or dikes when not constructed of waste rock or tailings and no process fluids are present; runoff from tailings dams or dikes When constructed of waste rock or tailings and no process fluids are present, if composed entirely of stormwater and not combining with mine drainage; concentration building if no contact with material piles;mill site if no contact with material piles; office or administrative building and housing if mixed with stormwater from industrial area; chemical storage area; docking facility if no excessive contact with waste product that would otherwise constitute mine drainage;explosive storage; fuel storage; vehicle and equipment maintenance area and building;parking areas (if necessary); power plant; truck wash areas if no excessive contact with waste product that would otherwise constitute mine drainage; unreclaimed, disturbed areas outside of active mining area; reclaimed areas released from reclamation requirements prior to December 17, 1990; and partially or inadequately reclaimed areas or areas not released from reclamation requirements. 8.G. 1.3 Covered Discharges from Exploration and Construction of Metal Mining and/or Ore Dressing Facilities. All stormwater discharges. 8.G.1.4 Covered Discharges from Facilities Undergoing Reclamation. All stormwater discharges. Stormwater Discharges Associated With Industrial Activity -Sector G 60 General Permit 8.G.2 Limitations on Coverage.8.G.2. 1 Prohibition of Stormwater Discharges. Stormwater discharges not authorized by this permit: discharges from active metal mining facilities that are subject to effluent limitation guidelines for the Ore Mining and Dressing Point Source Category (40 CFR Part 440).NOTE: Stormwater runoff from these sources are subject to 40 CFR Part 440 if they are mixed with other discharges subject to Part 440. In this case, they are not eligible for coverage under this permit. Discharges from overburden/waste rock and overburden/waste rock-related areas are not subject to 40 CFR Part 440 unless they: (1)drain naturally (or are intentionally diverted) to a point source; and (2) combine with"mine drainage" that is otherwise regulated under the Part 440 regulations. For such sources, coverage under this permit would be available if the discharge composed entirely of stormwater does not combine with other sources of mine drainage that are not subject to 40 CFR Part 440, and meets the other eligibility criteria contained in Part 1.2 of the permit. Permit applicants bear the initial responsibility for determining if they are eligible for coverage under this permit, or must seek coverage under another NPDES permit. EPA recommends that permit applicants contact the relevant NPDES permit issuance authority for assistance to determine the nature and scope of the "active mining area" on a mine-by-mine basis, as well as to determine the appropriate permitting mechanism for authorizing such discharges. 8.G.2.2 Prohibition of Non-Stormwater Discharges. Not authorized by this permit: adit drainage, and contaminated springs or seeps discharging from waste rock dumps that do not directly result from precipitation events (see also the standard Limitations on Coverage in Part 1.1.4).8.G.3 Definitions. The following definitions are not intended to supersede the definitions of active and inactive mining facilities established by 40 CFR 122.26(b)(14)(iii). 8.G.3.1 Mining operation -Consists of the active and temporarily inactive phases, and the reclamation phase, but excludes the exploration and construction phases.8.G.3.2 Exploration phase -Entails exploration and land disturbance activities to determine the viability of a site. The exploration phase is not considered part of "mining operations." 8.G.3.3 Construction phase -Includes the building of site access roads and removal of overburden and waste rock to expose mineable minerals. The construction phase is not considered part of "mining operations." 8.G.3.4 Active phase -Activities including the extraction, removal or recovery of metal ore.For surface mines, this definition does not include any land where grading has returned the earth to a desired contour and reclamation has begun. This definition is derived from the definition of "active mining area" found at 40 CFR 440.132(a). The active phase is considered part of "mining operations." Stormwater Discharges Associated With Industrial Activity -Sector G 61 General Permit 8.G.3.5 Reclamation phase -Activities undertaken, in compliance with applicable mined land reclamation requirements, following the cessation of the "active phase", intended to return the land to an appropriate post-mining land use in order to meet applicable Federal and State reclamation requirements. The reclamation phase is considered part of "mining operations." 8.G.3.6 Active metal mining facility -A place where work or other activity related to the extraction, removal, or recovery of metal ore is being conducted. For surface mines, this definition does not include any land where grading has returned the earth to a desired contour and reclamation has begun. This definition is derived from the definition of"active mining area" found at 40 CFR 440.132(a). 8.G.3.7 Inactive metal mining facility -A site or portion of a site where metal mining and/or milling occurred in the past but is not an active facility as defined above, and where the inactive portion is not covered by an active mining permit issued by the applicable State or Federal agency. An inactive metal mining facility has an identifiable owner /operator. Sites where mining claims are being maintained prior to disturbances associated with the extraction, beneficiation, or processing of mined materials and sites where minimal activities are undertaken for the sole purpose of maintaining a mining claim are not considered either active or inactive mining facilities and do not require an NPDES industrial stormwater permit.8.G.3.8 Temporarily inactive metal mining facility -A site or portion of a site where metal mining and/or milling occurred in the past but currently are not being actively undertaken, and the facility is covered by an active mining permit issued by the applicable State or Federal agency.8.G.3.9 Final Stabilization -A site or portion of a site is "finally stabilized" when it has implemented all applicable Federal and State reclamation requirements. 8.G.4 Technology-Based Effluent Limits for Clearing, Grading, and Excavation Activities. Clearing, grading, and excavation activities being conducted as part of the exploration and construction phase of mining activities are covered under this permit.8.G.4.1 Management Practices for Clearing, Grading, and Excavation Activities. 8.G.4. 1.1 Selecting and installing control measures. For all areas affected by clearing, grading, and excavation activities, you must select, design, install, and implement control measures that meet applicable Part 2 effluent limits.8.G.4.1.2 Good Housekeeping. Litter, debris, and chemicals must be prevented from becoming a pollutant source in stormwater discharges. 8.G.4.1.3 Retention and Detention of Stormwater Runoff For drainage locations serving more than one acre, sediment basins and/or temporary sediment traps should be used. At a minimum, silt fences, vegetative buffer strips, or equivalent sediment controls are required for all down slope boundaries (and for side slope boundaries as necessary based on individual site conditions) of the development area unless a sediment basin providing storage for a calculated Stormwater Discharges Associated With Industrial Activity -Sector G 62 General Permit volume of runoff from a 2-year, 24-hour storm or 3,600 cubic feet of storage per acre drained is provided. You are required to remove sediment from sediment traps or sedimentation ponds when design capacity has been reduced by 50 percent. Due to high sediment discharges from some Sector G facilities, permittees may need to implement a combination of structural BMP approaches to sufficiently decrease discharge of sediment from their facilities. 8.G.4.2 Inspection of Clearing, Grading, and Excavation Activities. 8.G.4.2.1 Inspection Frequency. Inspections must be conducted either at least once every 7 calendar days, or at least once every 14 calendar days and within 24 hours of the end of a storm event of 0.5 inches or greater. Inspection frequency may be reduced to at least once every month if the entire site is temporarily stabilized (pursuant to Part 8.G.4.3.2), if runoff is unlikely due to winter (e.g., site is covered with snow or ice) or frozen conditions, or construction is occurring during seasonal dry periods in arid areas and semi-arid areas.8.G.4.2.2 Location of Inspections. Inspections must include all areas of the site disturbed by clearing, grading, and/or excavation activities and areas used for storage of materials that are exposed to precipitation. Sedimentation and erosion control measures must be observed to ensure proper operation. Discharge locations must be inspected to ascertain whether erosion control measures are effective in preventing significant impacts to waters of the United States, where accessible. Where discharge locations are inaccessible, nearby downstream locations must be inspected to the extent that such inspections are practicable. Locations where vehicles enter or exit the site must be inspected for evidence of significant off-site sediment tracking.8.G.4.2.3 Inspection Reports. For each inspection required above, you must complete an inspection report. At a minimum, the inspection report must include the information required in Part 4.1.8.G.4.3 Requirements for Cessation of Clearing, Grading, and Excavation Activities. 8.G.4.3.1 Inspections and Maintenance. Inspections and maintenance of control measures, including BMPs, associated with clearing, grading, and excavation activities being conducted as part of the exploration and construction phase of a mining operation must continue until final stabilization has been achieved on all portions of the disturbed area, or until the commencement of the active mining phase for those areas that have been temporarily stabilized as a precursor to mining.8.G.4.3.2 Temporary Stabilization ofDisturbedAreas. Stabilization measures should be initiated immediately in portions of the site where clearing, grading and/or excavation activities have temporarily ceased, but in no case more than 14 days after the clearing, grading and/or excavation activities in that portion of the site have temporarily ceased. In arid, semiarid, and drought-stricken areas, or in areas subject to snow or freezing conditions, where initiating perennial Stormwater Discharges Associated With Industrial Activity -Sector G 63 General Permit vegetative stabilization measures is not possible within 14 days after mining, exploration, and/or construction activity has temporarily ceased, temporary vegetative stabilization measures must be initiated as soon as practicable. Until temporary vegetative stabilization is achieved, interim measures such as erosion control blankets with an appropriate seed base and tackifiers must be employed. In areas of the site, where exploration and/or construction has permanently ceased prior to active mining, temporary stabilization measures must be implemented to minimize mobilization of sediment or other pollutants until such time as the active mining phase commences. 8.G.4.3.3 Final Stabilization of Disturbed Areas. Stabilization measures should be initiated immediately in portions of the site where exploration and/or construction activities have permanently ceased, but in no case more than 14 days after the exploration and/or construction activity in that portion of the site has permanently ceased. In arid, semiarid, and drought-stricken areas, or in areas subject to snow or freezing conditions, where initiating perennial vegetative stabilization measures is not possible within 14 days after mining, exploration, and/or construction activity has permanently ceased, final vegetative stabilization measures must be initiated as soon as possible. Until final stabilization is achieved temporary stabilization measures, such as erosion control blankets with an appropriate seed base and tackifiers, must be used.8.G.5 Additional Technology-Based Effluent Limits.8.G.5.1 Employee Training. (See also Part 2.1.2.9) Conduct employee training at least annually at active and temporarily inactive sites.8.G.5.2 Stormwater Controls. Apart from the control measures you implement to meet your Part 2 effluent limits, consider implementing the following control measures at your site.The potential pollutants identified in Part 8.G.6.3 shall determine the priority and appropriateness of the control measures selected.8.G.5.2.1 Stormwater Diversions: Consider diverting stormwater away from potential pollutant sources. Following are some options: interceptor or diversion controls (e.g., dikes, swales, curbs, or berms); pipe slope drains; subsurface drains; conveyance systems (e.g., channels or gutters, open-top box culverts, and waterbars; rolling dips and road sloping; roadway surface water deflector and culverts); or their equivalents. 8.G.5.2.2 Capping: When capping is necessary to minimize pollutant discharges in stormwater, identify the source being capped and the material used to construct the cap.8.G.5.2.3 Treatment: If treatment of stormwater (e.g., chemical'or physical systems, oil and water separators, artificial wetlands) is necessary to protect water quality, describe the type and location of treatment used. Passive and/or active treatment of stormwater runoff is encouraged where practicable. Treated runoff may be discharged as a stormwater source regulated under this permit Stormwater Discharges Associated With Industrial Activity -Sector G 64 General Permit provided the discharge is not combined with discharges subject to effluent limitation guidelines for the Ore Mining and Dressing Point Source Category (40 CFR Part 440).8.G.5.3 Certification of Discharge Testing. (See also Part 5.1.3.4) Test or evaluate all outfalls covered under this permit for the presence of specific mining-related non-stormwater discharges such as seeps or adit discharges, or discharges subject to effluent limitations guidelines (e.g., 40 CFR Part 440), such as mine drainage or process water.Alternatively (if applicable), you may keep a certification with your SWPPP consistent with Part 8.G.6.6.8.G.6 Additional SWPPP Requirements. 8.G.6.1 Nature ofIndustrialActivities. (See also Part 5.1.2) Briefly document in your SWPPP the mining and associated activities that can potentially affect the stormwater discharges covered by this permit, including a general description of the location of the site relative to major transportation routes and communities. 8.G.6.2 Site Map. (See also Part 5.1.2) Document in your SWPPP the locations of the following (as appropriate): mining or milling site boundaries; access and haul roads; outline of the drainage areas of each stormwater outfall within the facility with indications of the types of discharges from the drainage areas; location(s) of all permitted discharges covered under an individual NPDES permit, outdoor equipment storage, fueling, and maintenance areas; materials handling areas; outdoor manufacturing, outdoor storage, and material disposal areas; outdoor chemicals and explosives storage areas;overburden, materials, soils, or waste storage areas; location of mine drainage (where water leaves mine) or other process water; tailings piles and ponds (including proposed ones); heap leach pads; off-site points of discharge for mine drainage and process water; surface waters; boundary of tributary areas that are subject to effluent limitations guidelines; and location(s) of reclaimed areas.8.G.6.3 Potential Pollutant Sources. (See also Part 5.1.3) For each area of the mine or mill site where stormwater discharges associated with industrial activities occur, identify the types of pollutants (e.g., heavy metals, sediment) likely to be present in significant amounts. Consider these factors: the mineralogy of the ore and waste rock (e.g., acid forming); toxicity and quantity of chemicals used, produced, or discharged; the likelihood of contact with stormwater; vegetation of site (if any); and history of significant leaks or spills of toxic or hazardous pollutants. Also include a summary of any existing ore or waste rock or overburden characterization data and test results for potential generation of acid rock. If any new data is acquired due to changes in ore type being mined, update your SWPPP with this information. 8.G.6.4 Documentation of Control Measures. Document all control measures that you implement consistent with Part 8.G.5.2. If control measures are implemented or planned but are not listed in Part 8.G.5.2 (e.g., substituting a less toxic chemical for a more toxic one), include descriptions of them in your SWPPP.8.G.6.5 Employee Training. All employee training(s) must be documented in the SWPPP.Stormwater Discharges Associated With Industrial Activity -Sector G 65 Stormwater Discharges Associated With Industrial Activity -Sector G 65 General Permit 8.G.6.6 Certification of Permit Coverage for Commingled Non-Stormwater Discharges: If you are able, consistent with Part 8.G.5.3 above, to certify that a particular discharge composed of commingled stormwater and non-stormwater is covered under a separate NPDES permit, and that permit subjects the non-stormwater portion to effluent limitations prior to any commingling, retain such certification with your SWPPP. This certification must identify the non-stormwater discharges, the applicable NPDES permit(s), the effluent limitations placed on the non-stormwater discharge by the permit(s), and the points at which the limitations are applied.8.G.7 Additional Inspection Requirements.(See also Part 4.1 and 8.G.4.2.) Except for areas of the site subject to clearing, grading, and/or excavation activities conducted as part of the exploration and construction phase, which are subject to Part 8.G.4.2.1, inspect sites at least quarterly unless adverse weather conditions make the site inaccessible. Sites which discharge to waters designated as outstanding waters or waters which are impaired for sediment or nitrogen must be inspected monthly. See Part 8.G.8.4 for inspection requirements for inactive and unstaffed sites.8.G.8 Monitoring and Reporting Requirements. (See also Part 6 of the permit.)Note: There are no Part 8.G.8 monitoring and reporting requirements for inactive and unstaffed sites.8.G.8.1 Benchmark Monitoring for Active Copper Ore Mining and Dressing Facilities.

Non-stormwater discharges from these sources are subject to NPDES permitting and may be subject to the effluent limitation guidelines under 40 CFR Part 440. Discharges from overburden/waste rock and overburden/waste rock-related areas are not subject to 40 CFR Part 440 unless: (1) it drains naturally (or is intentionally diverted) to a point source; and (2) combines with "mine drainage" that is otherwise regulated under the Part 440 regulations. For such sources, coverage under this permit would be available if the discharge composed entirely of stormwater does not combine with other sources of mine drainage that are not subject to 40 CFR Part 440, as well as meeting other eligibility criteria contained in Part 1.1 of the permit. Permit applicants bear the initial responsibility for determining the applicable technology-based standard for such discharges. EPA recommends that permit applicants contact the relevant NPDES permit issuance authority for assistance to determine the nature and scope of the"active mining area" on a mine-by-mine basis, as well as to determine the appropriate permitting mechanism for authorizing such discharges. 8.G.9. Termination of Permit Coverage 8.G.9.1 Termination of Permit Coverage for Sites Reclaimed After December 17, 1990. A site or a portion of a site that has been released from applicable state or federal reclamation requirements after December 17, 1990, is no longer required to maintain coverage under this permit. If the site or portion of a site reclaimed after December 17, 1990, was not subject to reclamation requirements, the site or portion of the site is no longer required to maintain coverage under this permit if the site or portion of the site has been reclaimed as defined in Part 8.G.7.2.8.G.9.2 Termination ofPermit Coverage for Sites Reclaimed Before December 17, 1990. A site or portion of a site that was released from applicable state or federal reclamation requirements before December 17, 1990, or that was otherwise reclaimed before December 17, 1990, is no longer required to maintain coverage under this permit if the site or portion of the site has been reclaimed. A site or portion of a site is considered to have been reclaimed if. (1) stormwater runoff that comes into contact with raw materials, intermediate byproducts, finished products, and waste products does not have the potential to cause or contribute to violations of state water quality standards, (2) soil disturbing activities related to mining at the sites or portion of the site have been completed, (3) the site or portion of the site has been stabilized to minimize soil erosion, and (4) as appropriate depending on location, size, and the potential to contribute pollutants to stormwater discharges, the site or portion of the site has been revegetated, will be amenable to natural revegetation, or will be left in a condition consistent with the post-mining land use.Stormwater Discharges Associated With Industrial Activity -Sector G 70 General Permit Part 8 -Sector-Specific Requirements for Industrial Activity Subpart H -Sector H -Coal Mines and Coal Mining-Related Facilities. You must comply with Part 8 sector-specific requirements associated with your primary industrial activity and any co-located industrial activities, as defined in Appendix A.

Determine whether excessive application of deicing chemicals occurs and Stormwater Discharges Associated With Industrial Activity -Sector S 117 General Permit adjust as necessary, consistent with considerations of flight safety.This evaluation should be carried out by the personnel most familiar with the particular aircraft and flight operations in question (versus an outside entity such as the airport authority). Consider using alternative deicing/anti-icing agents as well as containment measures for all applied chemicals. Also consider these control measure options (or their equivalents) for reducing deicing fluid use: forced-air deicing systems, computer-controlled fixed-gantry systems, infrared technology, hot water, varying glycol content to air temperature, enclosed-basket deicing trucks, mechanical methods, solar radiation, hangar storage, aircraft covers, and thermal blankets for MD-80s and DC-9s. Also consider using ice-detection systems and airport traffic flow strategies and departure slot allocation systems.8.S.3.1.7 Management of Runoff. (See also 2.1.2.6) Where deicing operations occur, implement a program to control or manage contaminated runoff to minimize the amount of pollutants being discharged from the site. Consider these control measure options (or their equivalents): a dedicated deicing facility with a runoff collection/ recovery system; using vacuum/collection trucks;storing contaminated stormwater/deicing fluids in tanks and releasing controlled amounts to a publicly owned treatment works; collecting contaminated runoff in a wet pond for biochemical decomposition (be aware of attracting wildlife that may prove hazardous to flight operations); and directing runoff into vegetative swales or other infiltration measures. Also consider recovering deicing materials when these materials are applied during non-precipitation events (e.g., covering storm sewer inlets, using booms, installing absorptive interceptors in the drains, etc.) to prevent these materials from later becoming a source of stormwater contamination. Used deicing fluid should be recycled whenever possible.8.S.3.2 Deicing Season. You must determine the seasonal timeframe (e.g., December-February, October -March, etc.) during which deicing activities typically occur at the facility. Implementation of control measures, including any BMPs, facility inspections and monitoring must be conducted with particular emphasis throughout the defined deicing season.

a. Any unanticipated bypass which exceeds any effluent limitation in the permit. (See 40 CFR 122.41(m)(3)(ii))

b. Any upset which exceeds any effluent limitation in the permit c. Violation of a maximum daily discharge limit for any numeric effluent limitation. (See 40 CFR 122.44(g).)

3. EPA may waive the written report on a case-by-case basis for reports under Appendix B, Subsection 12.F.2 if the oral report has been received within 24 hours.G. Other noncompliance.

You must report all instances of noncompliance not reported under Appendix B, Subsections 12.D, 12.E, and 12.F, at the time monitoring reports are submitted. The reports must contain the information listed in Appendix B, Subsection 12.F.H. Other information. Where you become aware that you failed to submit any relevant facts in a permit application, or submitted incorrect information in a permit application or in any report to the Permitting Authority, you must promptly submit such facts or information. Stormwater Discharges Associated With Industrial Activity -Appendix B B-9 General Permit B.13 Bypass.A. Definitions.

1. Bypass means the intentional diversion of waste streams from any portion of a treatment facility See 40 CFR 122.41(m)(1)(i).

2. Severe property damage means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production.

See 40 CFR 122.41(m)(1)(ii). B. Bypass not exceeding limitations. You may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Appendix B, Subsections 13.C and 13.D. See 40 CFR 122.41(m)(2). C. Notice.1. Anticipated bypass. If you know in advance of the need for a bypass, you must submit prior notice, if possible at least ten days before the date of the bypass.See 40 CFR 122.41(m)(3)(i).

2. Unanticipated bypass. You must submit notice of an unanticipated bypass as required in Appendix B, Subsection 12.F (24-hour notice). See 40 CFR 122.41 (m)(3)(ii).

D. Prohibition of bypass. See 40 CFR 122.41(m)(4).

1. Bypass is prohibited, and EPA may take enforcement action against you for bypass, unless: a. Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;b. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime.

This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and Stormwater Discharges Associated With Industrial Activity -Appendix B B-10 General Permit c. You submitted notices as required under Appendix B, Subsection 13.C.2. EPA may approve an anticipated bypass, after considering its adverse effects, if EPA determines that it will meet the three conditions listed above in Appendix B, Subsection 13.D. 1.B.14 Upset.A. Definition. Upset means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond your reasonable control. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. See 40 CFR 122.41(n)(1). B. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of Appendix B, Subsection 14.C are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. See 40 CFR 122.41(n)(2). C. Conditions necessary for a demonstration of upset. See 40 CFR 122.4l(n)(3). A permittee who wishes to establish the affirmative defense of upset must demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: 1. An upset occurred and that you can identify the cause(s) of the upset;2. The permitted facility was at the time being properly operated; and 3. You submitted notice of the upset as required in Appendix B, Subsection 12.F.2.b (24 hour notice).4. You complied with any remedial measures required under Appendix B, Subsection 4.D. Burden of proof. In any enforcement proceeding, you, as the one seeking to establish the occurrence of an upset, have the burden of proof. See 40 CFR 122.41(n)(4).

Procedures Relating to Endangered Species Protection E.1 Assessing the Effects of Your Discharge and Discharge-Related Activities You must follow the procedures in this appendix to assess the potential effects of applicable stormwater discharges, discharge-related activities, and allowable non-stormwater discharges on listed species and their critical habitat and determine which of the eligibility criterion (see Part E.2), if any, you qualify under. In accordance with Part 5.1.6.1 of this permit, you must keep documentation with your SWPPP to support your determination of eligibility under Part 1.1.4.5, including the process employed and results of the endangered species investigation. If you are seeking renewal of coverage under the MSGP, you must complete this analysis using any data collected when your site was fully active and operational, even if you are now claiming that your site is inactive and no industrial materials or activities are exposed to stormwater. If no such data exist for your facility, you should utilize the best available information from any industrial facility(ies) expected to discharge substantially similar effluents, based on the similarities of the general industrial activity, control measures, and runoff coefficients of their drainage areas. You should contact EPA if you need assistance in obtaining data from a facility with a substantially similar effluent.When evaluating the potential effects of your activities, you must consider effects to listed species or critical habitats within the "action area." Action area is defined in Appendix B as all areas affected directly or indirectly by the stormwater discharges, allowable non-stormwater discharges, and stormwater discharge-related activities, and not merely the immediate area involved in these discharges and activities. This includes areas beyond the footprint of the facility that are likely to be affected by stormwater discharges, discharge-related activities, and allowable non-stormwater discharges. For example, normal construction, operations and maintenance activities can result in noise impacts and discharges of pollutants into downstream areas which can increase the "action area" beyond the footprint of the facility."Facility" is defined in Appendix A.Step One: Determine if the Eligibility Requirements of Criterion B, C, or F Can Be Met.You should first determine whether you are eligible under Criteria 13, C, or F because of a previously completed ESA section 7 consultation, a previously issued ESA Section 10 permit, or because your activities were already addressed in another discharger's certification of eligibility as follows: The effects of your activities have been addressed in a consultation under ESA Section 7 on a separate Federal action (check box B corresponding to Criterion B).ii. The effects of your activities have been addressed through approval of a Habitat Conservation Plan under Section 10 of the ESA (check box C corresponding to Criterion C). Stormwater discharges from your industrial facility may be Stormwater Discharges Associated With Industrial Activity -Appendix E E-2 General Permit authorized by this MSGP if some activity is authorized through the issuance of a permit under section 10 of the ESA and that authorization addressed the effects of your stormwater discharges on federally-listed species and designated critical habitat. You must follow U.S. Fish and Wildlife Service (FWS) and/or National Marine Fisheries Service, also known as NOAA Fisheries (NMFS) procedures when applying for an ESA Section 10 permit (see 50 CFR 17.22(b)(1) for FWS and 222.22 for NMFS). Application instructions for section 10 permits for FWS and NMFS can be obtained by accessing the FWS and NMFS websites (www.fws.gov and www.nmfs.noaa.gov) or by contacting the appropriate FWS and NMFS regional office.iii. You are covered under the eligibility certification of another operator for the project area (check box F corresponding to Criterion F). Your stormwater discharges, discharge-related activities, and allowable non-stormwater discharges were already addressed in another discharger's certification of eligibility under Criteria A, B, C, D, or E, which also included your facility and determined that federally listed endangered or threatened species or designated critical habitat would not be jeopardized. To certify eligibility under this criterion there must be no lapse of coverage in the other operator's certification. By certifying eligibility under Criterion F, you agree to comply with any measures or controls upon which the other discharge certification under Criterion B, C, or D was based. If your certification is based on another operator's certification under Criterion E, that certification is valid only if you have documentation showing that the other operator had certified under Criterion E, and you provide EPA with the relevant supporting information in your NOI form. Certification under Criterion F is discussed in more detail in the Fact Sheet that accompanies this permit.Step Two: Determine if Listed Threatened or Endangered Species and Critical Habitat are Present in the Action Area.Next, you should first determine whether federally-listed species are likely to occur in your action area. If you determine that there is a federally-listed species likely to occur in your action area, follow Step 3. If you determine that there are no federally-listed species likely to occur in your action area, you can certify that the facility meets Criteria A (check box A corresponding to Criteria A).You can do this by obtaining a list of threatened and endangered species that are likely to occur in your general area, including the appropriate receiving water for your discharges. County-specific or sometimes township-specific lists of Federally threatened and endangered species are available from the local offices of FWS, and NMFS, or on their internet sites. The types of species that are likely to be present determine which Service office you should contact (in general, NMFS has jurisdiction over marine, estuarine, and anadromous species). Visit www.epa.gov/npdes/stormwater/cgp to find the appropriate site for your state or check with your local Service office. If there are listed species in your county or township, you must then determine, as best you are able, whether any of the species are likely to occur in your action area Stormwater Discharges Associated With Industrial Activity -Appendix E E-3 General Permit (use the Services or State and Tribal Heritage Centers, as necessary). General species information can be found at www.fws.gov/endangered.wildlife.html. You must also check to see if critical habitat has been designated and whether such areas overlap your action area. Critical habitat should be listed on the species list for your county or township available from the appropriate Service office. You can also find critical habitat designations at 50 CFR Parts 17 and 226 www.access.gpo.gov and at www.fws.gov/endangered/wildlife.htm i.If there are no listed species and no critical habitat areas that overlap your action area, or if your local FWS or NMFS indicates that listed species are not likely to occur in your action area, you have satisfied your eligibility obligations under Criterion A (check box A on the Notice of Intent Form). If there are listed species and if you determine or your local FWS, NMFS, or State or Tribal Heritage Center indicates that these species could occur in the action area, you will need to evaluate whether your action area supports habitat(s) that are suitable for listed species or the constituent elements of critical habitat. Your evaluation may utilize one or more of the following approaches: Gather information about the species and critical habitat that are likely to occur in your action area (www.fws.gov/endangered/wildlife.html). Conduct a visual inspection of the action area to assess the potential presence of listed species and their habitats. Compare the size and'types of habitats available in your action area and adjacent areas with the size and types of habitats used by listed species and constituent elements of critical habitat. This method may be particularly suitable for facilities where the action area is smaller in size or located in non-natural settings such as highly urbanized areas or industrial parks where there is little or no natural habitat, or for facilities that discharge directly into municipal separate storm sewer systems.Conduct a formal biological survey (typically performed by environmental consulting firms). In some cases, biological surveys may be an appropriate way to assess whether species are likely to be located in the action area and whether there could be adverse effects to such species. A biological survey may in some cases be useful in conjunction with Steps Two, Three or Four of these instructions. However, biological surveys can often be inconclusive and some survey methods may require a special State or Federal permit. You should coordinate with the appropriate Service office before conducting biological surveys for threatened and endangered species.Reference an environmental assessment completed for the site under the National Environmental Policy Act (NEPA). Such assessments may indicate whether listed species and critical habitats are likely to occur in the action area. Coverage under this MSGP may trigger a requirement for such an assessment for new sources (that is, dischargers subject to New Source Performance Standards under section 306 of the Clean Water Act). Other facilities might require an assessment under NEPA for other reasons, such as federal funding or other federal involvement in the facility. If the action area likely supports listed threatened or endangered species or critical habitat, you must evaluate the potential for impacts to species and/or habitat when following Steps Three through Five. Note that many but not all measures implemented to protect listed species under these steps will also protect critical habitat. Thus, meeting the Stormwater Discharges Associated With Industrial Activity -Appendix E E-4 General Permit eligibility requirements of this MSGP may require measures to protect critical habitat that are separate from those to protect listed species.Step Three: Determine ifyour Activities Are Not Likely to Adversely Affect Listed Threatened or Endangered Species or Designated Critical Habitat To receive MSGP coverage, you must analyze the effects of your activities, which may include not only your discharge, but also any construction, operation, and maintenance activities related to stormwater management. You must be able to conclude that your discharge and stormwater management related activities are not likely to adversely affect threatened or endangered species or designated critical habitat that are likely to occur in your action area. To arrive at this conclusion, you should be able to conclude that listed species and critical habitat are not likely to be exposed to the effects of your activities, or if they are exposed, they are not likely to respond to the effects, or if they do respond, the responses are not sufficient to reduce an individual's chances of surviving and reproducing or diminish the amount or suitability of constituent elements of critical habitat. Construction, operation, and maintenance of facilities related to your stormwater discharge can potentially result in the following adverse effects: Hydrological. Stormwater discharges may adversely affect receiving waters from pollutant parameters such as temperature, salinity or pH. These effects will vary with the amount of stormwater discharged and the volume and condition of the receiving water. Where a stormwater discharge constitutes a minute portion of the total volume of the receiving water, adverse hydrological effects are less likely. Industrial activity itself may also alter drainage patterns on a site where construction occurs, which can impact listed species, their habitat, and critical habitat.* Habitat. Outdoor activities, such as storage of materials and land disturbances associated with stormwater management-related activities, such as the installation or placement of stormwater control measures, may adversely affect listed species, their habitat, and critical habitat. Stormwater may drain or inundate listed species habitat.* Toxicity. Pollutants in stormwater may have toxic effects on listed species and adversely affect critical habitat. Exceedances of benchmarks, effluent limitation guidelines, or State or Tribal water quality requirements may be indicative of potential adverse affects on listed species or critical habitat.The scope of effects to consider will vary with each site. If you are having difficulty determining whether your facility is likely to adversely affect listed species or critical habitat, or one of the Services has already raised concerns to you, you must contact the appropriate office of the FWS or NMFS for assistance. If adverse effects are not likely, you have satisfied your eligibility obligations under Criterion E and you may proceed to submitting your NOI for coverage under the MSGP (check box E corresponding to Criterion E). As part of certifying your compliance with Criterion E, you must submit information to support your findings. If you are an existing discharger, you are required to (1) identify any pollutant parameters for which you have ever exceeded the benchmark or effluent limitations guideline, or have ever been found to have caused or contributed to an exceedance of an applicable water quality standard, or Stormwater Discharges Associated With Industrial Activity -Appendix E E-5 General Permit violated a State or Tribal water quality requirement; (2) provide a list of the federally-listed threatened or endangered species or their designated critical habitat that are likely to occur in the action area; and (3) provide your rationale supporting your determination that you qualify under Criterion E. If you are a new discharger, you must provide the list of species or critical habitat and the technical evaluation (described in (2) and (3) above, respectively), and you must also include a list of the potential pollutants in your discharge. If you can not yet conclude your stormwater discharge is not likely to adversely affect listed species or critical habitat, or if you conclude that your stormwater discharge could potentially adversely affect listed species or critical habitat, you must follow Step Four.Step Four: Determine if Measures Can Be Implemented to Avoid Adverse Effects or If Further Analysis Supports the Conclusion that Adverse Effects Are Not Likely.If you could not make a preliminary determination in Step 3 that adverse effects to listed species and/or critical habitat are not likely to occur, you can still receive coverage under Criterion E if appropriate measures are undertaken to avoid or eliminate the likelihood of adverse effects prior to applying for MSGP coverage. These measures may be relatively simple, e.g., re-routing a stormwater discharge to bypass an area where species are located, relocating control measures, or changing the "footprint" of the industrial activity. Provided you are able to install and implement appropriate measures, you may proceed to submitting your NOI for coverage under the MSGP (check box E corresponding to Criterion E). As part of certifying your compliance with Criterion E, you must submit information to support your findings. If you are an existing discharger, you are first required to (1) identify any pollutant parameters for which you have ever exceeded a benchmark or an effluent limitations guideline, or have ever been found to have caused or contributed to an exceedance of an applicable water quality standard, or violated a State or Tribal water quality requirement; (2) provide a list of the federally-listed threatened or endangered species or their designated critical habitat that are likely to occur in the action area; and (3) provide your rationale supporting your determination that you qualify under Criterion E, including a description of measures you will implement to avoid or eliminate the likelihood of adverse effects. If you are a new discharger, you must provide the list of species or critical habitat and the technical evaluation (described in (2) and (3) above, respectively), and you must also include a list of the potential pollutants in your discharge. If you cannot ascertain which measures to implement to avoid the likelihood of adverse effects, you must follow Step Five.Step Five: Determine if the Eligibility Requirements of Criteria D Can Be Met.Where adverse effects are likely and you are unable to avoid or eliminate the likelihood of adverse effects, you must contact the FWS and/or NMFS. However, you may still be eligible for MSGP coverage if any likely adverse effects can be addressed through meeting Criteria D as follows: You have coordinated your activities with the appropriate Service office (see Criterion D). In the absence of any other conditions set forth in Step Four, you may still be able to Stormwater Discharges Associated With Industrial Activity -Appendix E E-6 General Permit qualify for coverage under this MSGP if you coordinate with the FWS or NMFS and the Service provides a letter or memorandum concluding that permitting your stormwater discharges under the MSGP is consistent with the "not likely to adversely affect" determination for the MSGP. If you adopt measures to avoid or eliminate adverse effects, per the Service's requirements or recommendations, you must abide by those measures for the duration of your coverage under the MSGP. Any such measures must be described in the Stormwater Pollution Prevention Plan and are enforceable MSGP conditions and/or conditions for meeting the eligibility criteria in Part 1.1.4.5.You must comply with any terms and conditions imposed under the eligibility requirements to ensure that your storrnwater discharges, discharge-related activities, and allowable non-stormwater discharges are protective of listed species and/or critical habitat. See Part 2.3 of the permit. If the eligibility requirements cannot be met, and, maintained, then you are not eligible for coverage under this MSGP. In'these instances, you may consider applying to EPA for an individual permit.E.2 Eligibility Criterion As required by Part 1.1.4.5, you must meet one or more of the following six criteria (A-F)to be eligible for coverage under the permit for your stormwater discharge, discharge-related activities, and allowable non-stormwater discharges: Criterion A. No federally-listed threatened or endangered species or their designated critical habitat are likely to occur in the "action area"; or Criterion B. Consultation between a Federal agency and the U.S. Fish and Wildlife Service and/or the National Marine Fisheries Service (together, the "Services") under section 7 of the ESA has been concluded. Consultations can be either formal or informal, and would have occurred only as a result of a separate federal action (e.g., during application for an individual wastewater discharge permit or the issuance of a wetlands dredge and fill permit).The consultation must have addressed the effects of your facility's stormwater discharges, allowable non-stormwater discharges, and stormwater discharge-related activities on federally-listed threatened or endangered species and federally-designated critical habitat, and must have resulted in either: a biological opinion finding no jeopardy to federally-listed species or destruction/adverse modification of federally-designated critical habitat; or ii. written concurrence from the Service(s) with a finding that the facility's stormwater discharges associated with industrial activity, discharge-related activities and allowable non-stormwater discharges are not likely to adversely affect federally-listed species or federally-designated critical habitat; or Stormwater Discharges Associated With Industrial Activity -Appendix E E-7 General Permit Criterion C.Criterion D.Criterion E.Your industrial activities are authorized through the issuance of a permit under section 10 of the ESA, and authorization addresses the effects of the stormwater discharges associated with industrial activity, discharge-related activities, and allowable non-stormwater discharges on federally-listed species and federally-designated critical habitat; or Coordination between you and the U.S. Fish and Wildlife Service and/or the National Marine Fisheries Service has been concluded. The coordination must have addressed the effects of the facility's stormwater discharges associated with industrial activity, discharge-related activities, and allowable non-stormwater discharges on federally-listed threatened or endangered species and federally-designated critical habitat. The result of the coordination must be a written statement from the Service concluding that authorizing your stormwater discharges, discharge-related activities, and allowable non-stormwater discharges is consistent with the determination that the issuance of the MSGP is not likely to adversely affect federally-listed threatened or endangered species and federally-designated critical habitat. Any conditions or prerequisites deemed necessary to achieve consistency with the "not likely to adversely effect" determination become eligibility conditions for MSGP coverage, and permit requirements under Part 2.3; or Authorizing your stormwater discharges associated with industrial activity, discharge-related activities, and allowable non-stormwater discharges is consistent with the determination that the issuance of the MSGP is not likely to adversely affect any federally-listed endangered and threatened ("listed") species or designated critical habitat ("critical habitat"). To support your determination that you meet Criterion E, you must provide supporting documentation for your determination. If you are an existing discharger, you must provide the following information with your completed Notice of Intent (NOI) form: (1) a list of the federally-listed threatened or endangered species or their designated critical habitat that are likely to occur in the "action area"; (2) a list of the pollutant parameters for which you have ever exceeded the benchmark or applicable effluent limitations guideline, or for which you have ever been found to have caused or contributed to an exceedance of an applicable water quality standard or to have violated a State or Tribal water quality requirement (Part 9); and (3) your rationale supporting your determination that you meet Criterion E, including appropriate measures to be undertaken to avoid or eliminate the likelihood of adverse effects.ii. If you are a new discharger, you must provide the following information with your completed NOI form: (1) a list of the federally-listed threatened or endangered species or their designated critical habitat that are likely to occur in the "action area"; (2) a list of the potential pollutants in your discharge; and (3)your rationale supporting your determination that you meet Criterion E, including Stormwater Discharges Associated With Industrial Activity -Appendix E E-8 General Permit appropriate measures to be undertaken to avoid or eliminate the likelihood of adverse effects; or Criterion F.The facility's stormwater discharges associated with industrial activity, discharge-related activities, and allowable non-stormwater discharges were already addressed in another operator's valid certification of eligibility that included the industrial activities and there is no reason to believe that federally-listed species or federally-designated critical habitat not considered in the prior certification may be present or located in the "action area". To certify eligibility under this criterion there must be no lapse of coverage in the other operator's certification. By certifying eligibility under this criterion, you agree to comply with any measures or controls upon which the other operator's certification was based.You must comply with any applicable terms, conditions, or other requirements developed in the process of meeting the eligibility requirements of the criteria in this section to remain eligible for coverage under this permit. Documentation-must be kept with your SWPPP. If your certification is based on another operator's certification under Criterion E, that certification is valid only if you have documentation showing that the other operator had certified under Criterion E, and you provide EPA with the relevant supporting information required of existing dischargers in Criterion E (above, under subparagraph (i)) in your NOI form.Stormwater Discharges Associated With Industrial Activity -Appendix E General Permit Appendix F Procedures Relating to Historic Properties Preservation Stormwater Discharges Associated With Industrial Activity -Appendix F F-1 General Permit Appendix F -Procedures Relating to Historic Properties Preservation Section 106 of the National Historic Preservation Act (NHPA) requires Federal agencies to take into account the effects of Federal "undertakings" on historic properties that are either listed on, or eligible for listing on, the National Register of Historic Places. The term Federal"undertaking" is defined in the NHPA regulations to include a project, activity, or program of a Federal agency including those carried out by or on behalf of a Federal agency, those carried out with Federal financial assistance, and those requiring a Federal permit, license or approval. See 36 CFR 800.16(y). Historic properties are defined in the NHPA regulations to include prehistoric or historic districts, sites, buildings, structures, or objects that are included in, or are eligible for inclusion in, the National Register of Historic Places. This term includes artifacts, records, and remains that are related to and located within such properties. See 36 CFR 800.16(1). EPA's issuance of the Multi-Sector General Permit is a Federal undertaking within the meaning of the NHPA regulations. To address any issues relating to historic properties in connection with issuance of the permit, EPA has included criteria for applicants to certify that potential impacts of their covered activities on historic properties have been appropriately considered and addressed. Although individual applications for coverage under the general permit do not constitute separate Federal undertakings, the screening criteria and certifications provide an appropriate site-specific means of addressing historic property issues in connection with EPA's issuance of the permit. Applicants seeking coverage under the MSGP are thus required to make certain certifications regarding the potential effects of their stormwater discharge, allowable non-stormwater discharge, and discharge-related activities on properties listed or eligible for listing on the National Register of Historic Places.You must meet one or more of the four criteria (A-D), which are also included in Part 1.1.4.6, to be eligible for coverage under this permit.Criterion A.Criterion B.Criterion C.Your stormwater discharges and allowable non-stormwater discharges do not have the potential to have an effect on historic properties and you are not constructing or installing new stormwater control measures on your site that cause subsurface disturbance; or Your discharge-related activities (i.e., construction and/or installation of stormwater control measures that involve subsurface disturbance) will not affect historic properties; or Your stormwater discharges, allowable non-stormwater discharges, and discharge-related activities have the potential to have an effect on historic properties, and you have obtained and are in compliance with a written agreement with the State Historic Preservation Officer (SHPO), Tribal Historic Preservation Officer (THPO), or other tribal representative regarding measures to mitigate or prevent any adverse effects on historic properties, and you have either (1)obtained and are in compliance with a written agreement that outlines all such measures, or (2) been unable to reach agreement on such measures; or Stormwater Discharges Associated With Industrial Activity -Appendix F F-2 General Permit Criterion D. You have contacted the State Historic Preservation Officer, Tribal Historic Preservation Officer, or other tribal representative and EPA in writing informing them that you have the potential to have an effect on historic properties and you did not receive a response from the SHPO, THPO, or tribal representative within 30 days of receiving your letter.If you have been unable to reach agreement with a SHPO, THPO, or other tribal representative regarding appropriate measures to mitigate or prevent adverse effects, EPA may notify you of additional measures you must implement in order to be eligible for coverage under this permit.Activities with No Potential to Have an Effect on Historic Properties A determination that a Federal undertaking has no potential to have an effect on historic properties fulfills an agency's obligations under the NHPA. EPA has reason to believe that the vast majority of activities authorized under the MSGP have no potential to have effects on historic properties. The purpose of this permit is to control pollutants that may be transported in stormwater runoff from industrial facilities. EPA does not anticipate effects on historic properties from the pollutants in the stormwater and allowable non-stormwater discharges from these industrial facilities. Thus, to the extent EPA's issuance of this general permit authorizes discharges of such constituents, confined to existing stormwater channels or natural drainage areas; the permitting action does not have the potential to cause effects on historic properties. In addition, the overwhelming majority of sources covered under this permit will be facilities that are seeking renewal of previous permit coverage. These existing dischargers should have already addressed NHPA issues in the 2000 MSGP as they were required to certify that they were either not affecting historic properties or they had obtained written agreement from the applicable State Historic Preservation Officer (SHPO) or Tribal Historic Preservation Officer (THPO) regarding methods of mitigating potential impacts. Both existing and new dischargers must follow the historic property screening procedures to determine their eligibility. EPA is not aware of any impacts on historic properties from activities covered under the 2000 MSGP, or, for that matter, any need for a written agreement. Therefore, to the extent this permit authorizes renewal of prior coverage without relevant changes in operations, it has no potential to have an effect on historic properties. Activities with Potential to Have an Effect on Historic Properties EPA believes this permit may have some potential to have an effect on historic properties where permittees construct and/or install stormwater control measures that involve subsurface disturbance and impact less than one (1) acre of land to comply with this permit. (Ground disturbances of one (1) acre or more require coverage under a different permit, the Construction General Permit.) Where you have to disturb the land through the construction and/or installation of control measures, there is a possibility that artifacts, records, or remains associated with historic properties could be impacted. Therefore, if you are establishing new or altering existing control measures to manage your stormwater that will involve subsurface ground disturbance of less than one (1) acre, you will need to ensure (1) that historic properties will not be impacted by Stormwater Discharges Associated With Industrial Activity -Appendix FI F-3 General Permit your activities or (2) that you have consulted with the appropriate SHPO, THPO, or other tribal representative regarding measures that would mitigate or prevent any adverse effects on historic properties. Examples of Control Measures Which Involve Subsurface Disturbance EPA reviewed typical control measures currently employed to determine which practices involve some level of earth disturbance. The types of control measures that are presumptively expected to cause subsurface ground disturbance include: o Dikes* Berms o Catch Basins* Ponds o Ditches o Trenches o Culverts o Land manipulation: contouring, sloping, and grading o Channels o Perimeter Drains o Swales EPA cautions dischargers that this list is non-inclusive. Other control measures that involve earth disturbing activities that are not on this list must also be examined for the potential to affect historic properties. Historic Property Screening Process You should follow the following screening process in order to certify your compliance with historic property eligibility requirements under this permit (see Part 1.1.4.6). The following four steps describe how applicants can meet the permit eligibility criteria for protection of historic properties under this permit: Step One: Are you an existing facility that is reapplyingfor certification under the 2008 MSGP?If you are an existing facility you should have already addressed NHPA issues. To gain coverage under the 2000 MSGP you were required to certify that you were either not affecting historic properties or had obtained written agreement from the relevant SHPO or THPO regarding methods of mitigating potential impacts. As long as you are not constructing or installing any new stormwater control measures then you have met eligibility Criterion A of the MSGP. After you submit your NOI, there is a 30-day waiting period during which the SHPO, THPO, or other tribal representative may review your NOI. The SHPO, THPO, or other tribal representative may request that EPA hold up authorization based on concerns about potential adverse impacts to historic properties. EPA will evaluate any such request and notify you if any additional measures to address adverse impacts to historic properties are necessary. Stormwater Discharges Associated With Industrial Activity -Appendix F F-4 General Permit If you are an existing facility and will construct or install stormwater control measures that require subsurface disturbance of less than one (1) acre then you should proceed to Step Three. (Note: Construction activities disturbing one (1) acre or more are not eligible for coverage under this permit.)If you are a new facility then you should proceed to Step Two.Step Two: Are you constructing or installing any stormwater control measures that require subsurface disturbance of less than one (1) acre?If, as part of your coverage under this permit, you are not building or installing control measures on your site that cause less than one (1) acre of subsurface disturbance, then your discharge-related activities do not have the potential to have an effect on historic properties. You have no further obligations relating to historic properties. You have met eligibility Criterion A of the MSGP. After you submit your NOI, there is a 30-day waiting period during which the SHPO, THPO, or other tribal representative may review your NOL. The SHPO, THPO, or other tribal representative may request that EPA hold up authorization based on concerns about potential adverse impacts to historic properties. EPA will evaluate any such request and notify you if any additional measures to address adverse impacts to historic properties are necessary. If the answer to the Step Two question is yes, then you should proceed to Step Three.Step Three: Have prior earth disturbances determined that historic properties do not exist, or have prior disturbances precluded the existence of historic properties? If previous construction either revealed the absence of historic properties or prior disturbances preclude the existence of historic properties, then you have no further obligations relating to historic properties. You have met eligibility Criterion B of the MSGP. After you submit your NOI, there is a 30-day waiting period during which the SHPO, THPO, or other tribal representative may review your NOI. The SHPO, THPO, or other tribal representative may request that EPA hold up authorization based on concerns about potential adverse impacts to historic properties. EPA will evaluate any such request and notify you if any additional measures to address adverse impacts to historic properties are necessary. If the answer to the Step Three question is no, then you should proceed to Step Four.Step Four: Contact the appropriate historic preservation authorities Where you are building and/or installing control measures affecting less than one (1) acre of land to control stormwater or allowable non-stormwater discharges associated with this permit, and the answer to Step Three is no, then you should contact the relevant SHPO, THPO, or other tribal representative to determine the likelihood that artifacts, records, or remains are potentially present on your site. This may involve examining local records to determine if historic artifacts have been found in nearby areas, as well as limited surface and subsurface examination carried out by qualified professionals. Stormwater Discharges Associated With Industrial Activity -Appendix F F-5 General Permit If through this process it is determined that such historic properties potentially exist and may be impacted by your construction or installation of control measures, you should contact the relevant SHPO, THPO, or tribal representative in writing and request to discuss mitigation or prevention of any adverse effects. The letter should describe your facility, the nature and location of subsurface disturbance activities that are contemplated, any known or suspected historic properties in the area, and any anticipated effects on such properties. The letter should state that if the SHPO, THPO, or tribal representative does not respond within 30 days of receiving your letter, you may submit your NOI without further consultation. EPA encourages applicants to contact the appropriate authorities as soon as possible in the event of a potential adverse effect to an historic property.If the SHPO, THPO, or tribal representative sent you a response within 30 days of receiving your letter and you enter into, and comply with, a written agreement with the SHPO, THPO, or other tribal representative regarding how to address any adverse impacts on historic properties, you have met eligibility Criterion C. In this case, you should retain a copy of the written agreement consistent with Part 5.1.6.2 of the MSGP. After you submit your NOI, there is a 30-day waiting period during which the SHPO, THPO, or other tribal representative may review your NOI. The SHPO, THPO, or other tribal representative may request that EPA delay authorization based on concerns about potential adverse impacts to historic properties. However, EPA would generally accept any written agreement as fully addressing such concerns unless new information was brought to the Agency's attention that was not considered in your previous discussions with the SHPO, THPO or other tribal representative. If you receive a response within 30 days after the SHPO, THPO, or tribal representative received your letter and you consult with the SHPO, THPO or tribal representative regarding adverse impacts to historic properties and measures to mitigate them but an agreement cannot be reached between you and the SHPO, THPO, or other tribal representative, you have still met the eligibility for Criterion C. In this case you should include in your SWPPP a brief description of potential effects to historic properties, the consultation process, any measures you will adopt to address the potential adverse impacts, and any significant remaining disagreements between you and the SHPO, THPO or other tribal representative. After you submit your NOI, there is a 30-day waiting period during which the SHPO, THPO, or other tribal representative may review your NOI. The SHPO, THPO, or other tribal representative may request that EPA delay authorization based on concerns about potential adverse impacts to historic properties. EPA will evaluate any such request and notify you if any additional measures to address adverse impacts to historic properties are necessary. If you have contacted the SHPO, THPO, or tribal representative in writing regarding your potential to have an effect on historic properties and the SHPO, THPO, or tribal representative did not respond within 30 days of receiving your letter, you have met eligibility Criterion D. You are advised to get a receipt from the post office or other carrier confirming the date on which your letter was received. In this case, you should submit a copy of your letter notifying the SHPO, THPO or tribal representative of potential impacts with your NOI. After you submit your NOI, there is a 30-day waiting period during which the SHPO, THIPO, or other tribal representative may review your NOT. The SHPO, THPO, or other tribal representative may Stormwater Discharges Associated With Industrial Activity -Appendix F F-6 General Permit request that EPA hold up authorization based on concerns about potential adverse impacts to historic properties. EPA will evaluate any such request and notify you if any additional measures to address adverse impacts to historic properties are necessary. Addresses for State Historic Preservation Officers and Tribal Historic Preservation Officers may be found on the Advisory Council on Historic Preservation's website (www.achp.gov/programs.html). In instances where a Tribe does not have a Tribal Historic Preservation Officer, you should contact the appropriate Tribal government office when responding to this permit eligibility condition. Stormwater Discharges Associated With Industrial Activity -Appendix F F-7 General Permit Appendix G Notice of Intent (NOI) Form Stormwater Discharges Associated With Industrial Activity -Appendix G G-1 General Permit Appendix G -Notice of Intent (NOI) Form To obtain coverage under this permit, you must submit a Notice of Intent (NOI). You must submit an NOI using either (1) EPA's Electronic Notice of Intent (eNOI) system, available at www.epa.gov/npdes/eNOl, or (2) file a paper copy of the NOI, a copy of which follows.Stormwater Discharges Associated With Industrial Activity -Appendix G G-2 UNITED STATES ENVIRONMENTAL PROTECTION AGENCY Form Approved.NPDES WASHINGTON, DC 20460 OMB No. 2040-0086 FORM -6NOTICE OF INTENT (NOI) FOR STORMWATER DISCHARGES ASSOCIATED WITH INDUSTRIAL ACTIVITY UNDER THE NPDES MULTI-SECTOR GENERAL PERMIT Submission of this completed Notice of Intent (NOI) constitutes notice that the operator identified in Section B of this form requests authorization to discharge pollutants to waters of the United States from the facility or site identified in Section C under EPA's NPDES Stormwater Multi-Sector General Permit (MSGP) for industrial stormwater.

In these instances, EPA will notify you in writing of the delay or the request for submission of an individual NPDES permit application. EPA will post these NOls on its website at www.epa.gov/npdes/enoi. Who Must File a Notice of Intent with EPA?Under section 402(p) of the Clean Water Act (CWA) and regulations at 40 CFR Part 122, stormwater discharges associated with industrial activity are prohibited to waters of the United States unless authorized under a National Pollutant Discharge Elimination System (NPDES) permit. You can obtain coverage under the MSGP by submitting a completed NOI if you operate a facility: " that is located in a jurisdiction where EPA is the permitting authority, listed in Appendix C of the MSGP," that discharges stormwater associated with industrial activities, identified in Appendix D of the MSGP," that meets the eligibility requirements in Part 1.1 of the permit," that develops a stormwater pollution prevention plan (SWPPP) in accordance with Part 5 of the MSGP; and" that installs and implements control measures in accordance with Part 2 to meet numeric and non-numeric effluent limits.If you are unsure if you need an NPDES stormwater permit, contact your EPA or State NPDES stormwater permit program. Contacts are listed at www.epa.gov/npdes/stormwatercontacts. One NOI must be submitted for each facility or site for which you are seeking permit coverage. You do not need to submit separate NOls for each type of industrial activity present at your facility, provided your SWPPP covers all activities. When to File the NOI Form Do not file your NOI until you have obtained and thoroughly read a copy of the.MSGP. A copy of the MSGP is located on the EPA website (www.epa.qov/npdes/stormwater/msqp). The MSGP describes procedures to ensure your eligibility, prepare your SWPPP, install and implement appropriate stormwater control measures, and complete the NOI form questions -all of which must be done before you sign the NOI certification statement attesting to the EPA FORM 3510-6 (Revised 09-2008)accuracy and completeness of your NOI. You will also need a copy of the MSGP once you have obtained coverage so that you can comply with the implementation requirements of the permit.Where to File the NOI Form EPA encourages you to complete the NOI form electronically via the Internet.EPA's Electronic Notice of Intent System (eNOI) can be found at www.epa.qov/nodes/enoi. Filing electronically is the fastest way to obtain permit coverage and help ensure that your NOI is complete. If you choose not to file electronically, you must send the NOI to one of the addresses listed below.NOls sent regular mail: Stormwater Notice Processing Center (4203M)USEPA 1200 Pennsylvania Avenue, NW Washington, DC,20460 NOls sent overnight/express mail: Stormwater Notice Processing Center EPA East Building, Rm. 7420 1201 Constitution Avenue, NW Washington, DC 20004 202-564-9545 If you have questions, please contact EPA's Stormwater Notice Processing Center toll free at (866) 352-7755." If you file a paper NOI, please submit the original with a signature in ink-Do Not Send Copies. Also, faxed copies will not be accepted." Your SWPPP does not need to be submitted for review unless specifically requested by EPA or as otherwise required in Part 9 of the MSGP (State, Territory, and Tribal requirements). You must keep a copy of your SWPPP on-site or otherwise make it available to facility personnel responsible for implementing provisions of the permit.Completing the NOI Form To complete this form, type or print in uppercase letters in the appropriate areas only. Please make sure you complete all questions. Make sure you make a photocopy for your records before you send the completed original form to the address above. You may also use this paper form as a checklist for the information you will need when filing an NOI electronically via EPA's eNOI system.Section A. Permit Number Appendix C of the MSGP 2008 contains a list of geographic areas covered by the permit. If your facility is located in one of the listed areas, include the appropriate permit number in this section. (For example, if you facility is located in Massachusetts, and not on Indian Lands, you would write MAR050000 in this space.) If your facility is located in an area not covered by the MSGP, please contact your EPA Region, state or territorial NPDES stormwater coordinator (see www.epa.qov/npdes/stormwatercontacts for a list of contacts). Section B. Facility Operator Information

1. Provide the legal name of the person, firm, public organization or any other public entity that operates the facility described in this application.

An operator of a facility is a legal entity that controls the operation of the facility.2. Provide the Employer Identification Number (EIN from the Internal Revenue Service (IRS)), commonly referred to as your taxpayer ID number. If the operator does not have an EIN, enter "NA" in the space provided.3. Provide the operator's mailing address, telephone number, fax number (optional), and email address. Correspondence will be sent to this address.Section C. Facility Information

1. Enter the facility's official or legal name. Unless the name of your facility has changed, please use the same name provided on prior NOls or permit applications.

You can use EPA's NOI Search website (www.epa.qov/npdes/noisearch) to view your previous NOI.2. Indicate if industrial stormwater discharges from your facility were previously covered by an NPDES permit.2a.lf your facility was covered by EPA's MSGP-2000, please include the tracking number that you received in your confirmation letter or email from EPA's Stormwater Notice Processing Center. You can find the tracking number assigned to your previous NOI on EPA's NOI Search website (www.epa.gov/npdes/noisearch). 2bl.If your facility was not previously covered by an NPDES permit and discharged industrial stormwater, then indicate if it was in operation before October 30, 2005 and not covered under the MSGP 2000. If you select "yes" to this question then you have a 30 day waiting period before you are authorized to discharge. 2b2.lf you select "no" in C.2.b.1, then indicate if your facility discharged stormwater between October 30, 2005 and January 5, 2009. If you select 'yes" to this Page 5 of 7 question then you have a 30 day waiting period before you are authorized to discharge. If you select "no" to this question and you post your SWPPP on the Internet and provide EPA the URL in E.2, then you have a 30 day waiting period before you are authorized to discharge. If you select "no" to this question, but do not post your SWPPP on the Internet and therefore do not answer E.2, then you have a 60 day waiting period before you are authorized to discharge. 3.a-e. Enter the street address, including city, state, zip code, county or similar government subdivision of the actual physical location of the facility. Do not use a P.O. Box.3.f-g. Provide the facility latitude and longitude in one of three formats: (1) degrees, minutes, seconds; (2) degrees, minutes, decimal; or(3) degrees decimal. You can obtain your facility's latitude and longitude though Global Positioning System (GPS) receivers, U.S. Geological Survey (USGS) quadrangle or topographic maps, and EPA's web-based siting-tools, among other methods.Refer to www.epa.qov/npdes/stormwater/msqp for guidance on the use of these methods. For consistency, EPA requests you take measurements from the location of your facility's stormwater outfall. Outfalls are locations where the stormwater exits the facility, including pipes, ditches, swales, and other structures that transport stormwater. If there is more than one outfall present, measure at the primary outfall (i.e., the outfall with the largest volume of stormwater discharge associated with industrial activity). 3.h. Identify the data source that you used to determine the facility latitude and longitude. If you did not use a USGS quadrangle or topographic map, the EPA website, or GPS receivers, then select "Other" and write the method used on the line provided. If you used a USGS quadrangle or topographic map, write the map scale on the line provided. Scale should be identified on the map.4. Enter the estimated area of industrial activity at your site exposed to stormwater, in acres.5. Indicate if the facility is considered a "federal facility" -Federal facilities include any buildings, installations, structures, land, public works, equipment, aircraft, vessels, and other vehicles and property, owned or leased by the federal government.

6. Indicate whether the facility is located in indian Country, and, if so, provide the name of the reservation, if applicable.

Section D. Discharge Information

1. Indicate whether stormwater from your site will be discharged into a municipal separate storm sewer system (MS4). An MS4 is a conveyance or system of conveyances, including roads with drainage systems, municipal streets, catch basins, storm drains, curbs and gutters, ditches and man-made channels, owned or operated by a state, city, town, borough, county, parish, district, association or other public body, used to collect or convey stormwater.

If you check "Yes" then identify the name of the MS4 operator on the line provided. If you are uncertain of the MS4 operator, contact your local government for that information. MS4s are different than combined sewers, which are designed to convey both stormwater and sanitary wastewater. Discharges to combined sewers do not require an NPDES permit but may be subject to other CWA requirements (contact the combined sewer operator for more information).

2. Enter information regarding your discharge.

If additional space is needed fill out Attachment 1.2a. Indicate in column "a" of the table the name(s) of the receiving water(s) into which stormwater from your facility will discharge. Also provide in parentheses the name of the impaired water (and segment, if applicable) into which your stormwater is discharged. If you identified more than on receiving water for your facility, indicate the first receiving water and complete question 2b and 2.b.1-3 (if applicable), before entering the next receiving water. The EPA's Water Locator Tool can help you identify the closest receiving water to your facility (www.epa.qov/npdes/msqp). Your receiving water may be a lake, stream, river, ocean, wetland or other waterbody, and may or may not be located adjacent to your facility. Your stormwater may discharge directly to the receiving water or indirectly via a storm sewer system, an open drain or ditch, or other conveyance structure. Do NOT list a man-made conveyance, such as a storm sewer system, as your receiving water. Indicate the first receiving water your stormwater discharge enters. For example, if your discharge enters a storm sewer system, that empties into Trout Creek, which flows into Pine River, your receiving water is Trout Creek, because it is the first waterbody your discharge will reach. Similarly, a discharge into a ditch that feeds Spring Creek should be identified as "Spring Creek" since the ditch is a manmade conveyance. If you discharge into a municipal separate storm sewer system (MS4), you must identify the waterbody into which that portion of the storm sewer discharges. That information should be readily available from the operator of the MS4.2b. Indicate in column Vb" of the table whether you discharge directly to an impaired water (lake, stream segment, estuary, etc), listed as "impaired" under section 303(d) of the Clean Water Act. Each state water quality agency maintains a list of waters that are impaired. Most state agencies publish these lists online. The EPA's Water Locator Tool may also help you identify if the nearest receiving water is impaired (www.eoa.qov/npdes/msqo). If you discharge into a stream EPA FORM 3510-6 (Revised 09-2008)segment that is upstream of a listed impaired water but which is not itself on the State's impaired waters list, answer "no" to this question. In this case, requirements in the MSGP for discharges into impaired waters do not apply to you, unless notified otherwise by EPA.Answer the following three questions only if you answered "Yes" to D 2.b: 2b1. Provide the pollutant(s) listed as causing the impairment in the water identified in D.2.b.1 above. Enter each pollutant individually on a separate row in the table.2b2. Out of the pollutant(s) that you identified in D.2.b.1 above, indicate which pollutants you believe will be present in your discharge. If you do not expect the pollutant(s) to be in your discharge, then select "no." 2b3.lndicate the pollutant(s) that have a Total Maximum Daily Load (TMDL) for the impaired stream segment that you identified in D.2.b.2 above. Check with your state water quality agency for lists of waters with approved or established TMDLs. See www.epa.qov/npdes/msqp for more information.

3. Water Quality Standards 3a.lf you selected "no" in C.2 indicating that stormwater discharges from your facility have not been previously covered under an NPDES permit, then you are considered a new discharger and must answer this question; otherwise you are considered an existing discharger and may skip this question.

State water quality agencies are responsible for setting water quality standards for waters within the state's boundaries. Check EPA's website (www.epa.gov/npdes/msqp) to determine if the water(s) that you discharge into are designated as a "Tier 2 (or Tier 2.5) water" (See Appendix A of the MSGP 2008 for definitions of "Tier 2 water" and "Tier 2.5 water"). If you discharge into these waters, EPA may impose additional permit conditions to ensure that you do not violate the State's antidegradation policy.3.b Idenitfy whether your receiving water is designated as a Tier 3 waterbody. Go to www.epa.qov/npdes/msqp for a list of Tier 3 waterbodies. Note that new discharges into designated Tier 3 waters are not eligible for coverage under the MSGP 2008.4. Federal Effluent Limitation Guidelines and Sector-Specific Requirements 4.a-b. Depending on your industrial activities, your facility may be subject to effluent limitation guidelines which include additional effluent limits and monitoring requirements for your facility. Please review these requirements, described in Part 2.1.3 of the MSGP, and check any appropriate boxes on the NOI form.4.c. For Sector S facilities (Air Transportation), indicate whether you anticipate that the entire airport facility will use more than 100,000 gallons of glycol-based deicing/anti-icing chemicals and/or 100 tons or more of urea on an average annual basis. If so, additional effluent limits and monitoring conditions apply to your discharge (see Part 8 Sector S of the MSGP 2008).5. List the four-digit Standard Industrial Classification (SIC) code and/or two character activity code that best describes the primary industrial activities performed by your facility under which you are required to obtain permit coverage. Your primary industrial activity includes any activities performed on-site which are (1) identified by the facility's one SIC code for which the facility is primarily engaged; and (2) included in the narrative descriptions of 40 CFR 122.26(b)(14)(i), (iv), (v), or (vii), and (ix). See Appendix D of the MSGP for a complete list of SIC codes and activities codes.6. If your site has co-located industrial activities that are not identified as your primary industrial activity, identify the sector and subsector codes that describe these other industrial activities. For a complete list of sector and subsector codes, see Appendix D of the MSGP.7.a-b Indicate whether your facility is currently inactive and unstaffed. If so then indicate whether your facility will be inactive and unstaffed for the entire permit term, or if not, specify the specific length of time in units of days, weeks, months, or years (e.g. 3 months) that you expect the facility to be inactive and unstaffed. Section E. Facility Contact Information and SWPPP Location 1.a-c. Identify the name, telephone number, and email address of the person who will serve as a contact for EPA on issues related to stormwater management at your facility. This person should be able to answer questions related to stormwater discharges, the SWPPP, and other issues related to stormwater permit coverage, or have immediate access to individuals with that knowledge. This person does not have to be the facility operator, but should have intimate knowledge of stormwater management activities at the facility.2. If you are making your Stormwater Pollution Prevention Plan publicly available on a website provide the appropriate Internet URL address. (Please note that by posting your SWPPP on the web, you may qualify for a shortened authorization waiting period. See Table 1-2 of the MSGP for more information.) Section F. Endangered Species Protection

1. Based on the instruction provided in Appendix E of the MSGP 2008, indicate which permit criterion (A,B,C,D,E, or F) listed in Part 1.1.4.5 you are using to satisfy your eligibility obligations for protection of endangered and threatened species, and designated critical habitat.Page 6 ot 7 2.a. If you select criterion E (not likely to adversely affect), list those federally-listed endangered or threatened species and any federally-listed designated critical habitat expected to exist in proximity to your facility.2.b List the pollutants that you expect to be present in your stormwater discharge.

Include any pollutants that you may have included in D.2.b.3 above.2.c If you selected "yes" in C.2 then you are considered an existing discharger and must answer all the questions in F.2.c.1-5; otherwise you are considered a new discharger and may skip the questions under F.2.c. If you are an exisfing discharger who was previously covered under the MSGP 2000, indicate whether you have any previous effluent monitoring data.2.cl-2.If you select "No," to F.2.c then indicate why you don't have any data. Also indicate if you have any other data characterizing pollutants in your stormwater discharge. 2.c.3. If you select 'Yes," to F.2.c then indicate whether you exceeded any benchmark. 2.c.4 Indicate whether you have exceeded any applicable effluent limitation guideline, or caused or contributed to an exceedance of state or tribal water quality requirement(s). 2.c.5. If you select "Yes" to F.2.c.3.and/or F.2.c.4 then indicate the pollutant parameters for which you exceeded the benchmark, applicable effluent limitation guideline, or State or Tribal water quality requirement(s). 2.d. Attach your supporting rationale for your determination of the applicability of Criterion E for your facility (applies to both new and existing dischargers). Your documentation should address species and habitat listed in F.2.a and the potential effects of pollutants listed in F.2.b on the listed species and habitat.This should include consideration of any available data characterizing pollutants in your stormwater discharge, or in the discharge of similar facilities if data for you facility is not available, that may be of concern to listed species.3. If you select Criterion F (already addressed in another operators valid certification), provide the tracking number that the operator received in their confirmation letter or email from EPA's NOI Processing Center (see Appendix E). You can find the tracking number assigned to your previous NOI on EPA's NOI Search website (www.epa.gov/npdes/noisearch). An example where criterion F may apply includes airports where several individual aidines have applied for coverage under the MSGP, and the entire airport also has applied for or obtained coverage. If the airport has already certified under Appendix E, and that certification addresses any potential impacts from the individual airlines, then the airlines may reference the airport's permit tracking number.Section G. Historic Preservation Based on the instruction provided in Appendix F of the MSGP 2008, indicate which permit criterion (A, B, C, or D) listed in Part 1.1.4.6 of the MSGP you used to satisfy your eligibility obligations for protection of historic properties. Section H. Certification Certification statement and signature (see Section B.1 1 of Appendix B of the MSGP for more information).

Authorized Representative I I I I I I I Title: III I I I I Printed Name: Date Signed: Signature: Date Signed: General Permit Appendix J Calculating Hardness in Receiving Waters for Hardness Dependent Metals Stormwater Discharges Associated With Industrial Activity -Appendix J J-1 -General Permit Appendix J. Calculating Hardness in Receiving Waters for Hardness Dependent Metals Overview EPA adjusted the benchmarks for six hardness-dependent metals (i.e., cadmium, copper, lead, nickel, silver, and zinc) to further ensure compliance with water quality standards and provide additional protection for endangered species and their critical habitat. For any sectors required to conduct benchmark samples for a hardness-dependent metal, EPA includes 'hardness ranges'from which benchmark values are determined. To determine which hardness range to use, you must collect data on the hardness of your receiving water(s). Once the site-specific hardness data have been collected, the corresponding benchmark value for each metal is determined by comparing where the hardness data fall within 25 mg/L ranges, as shown in Table 1.Table 1. Hardness Ranges to Be Used to Determine Benchmark Values for Cadmium, Copper, Lead, Nickel, Silver, and Zinc.All Units '" Benchmark Values (mgiL/ total)mg/L Cadmium Copper Lead Nickel Silver Zinc 0.0005 0.0038 0.014 0.15 0.0007 0.04 0.0008 0.0056 0.023 0.20 0.0007 0.05._i5'.

You may select one of three methods to determine hardness, including; individual grab sampling, grab sampling by a group of operators which discharge to the same receiving water, or using third-party data. Regardless of the method used, you are responsible for documenting the procedures used for determining hardness values. Once the hardness value is established, you are required to include this information in your first benchmark report submitted to EPA so that the Agency can make appropriate comparisons between your benchmark monitoring results and the corresponding benchmark. You must retain all report and monitoring data in accordance with Part 7.5 of the permit. The three method options for determining hardness are detailed in the following sections.(1) Permittee Samples for Receiving Stream Hardness This method involves collecting samples in the receiving water and submitting these to a laboratory for analysis. If you elect to sample your receiving water(s) and submit samples for Stormwater Discharges Associated With Industrial Activity -Appendix J J-2 General Permit analysis, hardness must be determined from the closest intermittent or perennial stream downstream of your point of discharge. The sample can be collected during either dry or wet weather. Collection of the sample during wet weather is more representative of conditions during stormwater discharges; however, collection of in-stream samples during wet weather events may be impracticable or present safety issues.Hardness must be sampled and analyzed using approved methods as described in 40 CFR Part 136 (Guidelines Establishing Test Procedures for the Analysis of Pollutants). (2) Group Monitoring for Receiving Stream Hardness You can be part of a group of permittees discharging to the same receiving waters and collect samples that are representative of the hardness values for all members of the group. In this scenario, hardness of the receiving water must be determined using 40 CFR Part 136 procedures and the results shared by group members. To use the same results, hardness measurements must be taken on a stream reach within a reasonable distance of the discharge points of each of the group members.(3) Collection of Third-Party Hardness Data You can submit receiving stream hardness data collected by a third party provided the results are collected consistent with the approved 40 CFR Part 136 methods. These data may come from a local water utility, previously conducted stream reports, TMDLs, peer reviewed literature, other government publications, or data previously collected by the permittee. Data should be less than 10 years old.Water quality data for many of the nation's surface waters are available on-line or by contacting EPA or a state environmental agency. EPA's data system STORET, short for STOrage and RETrieval, is a repository for receiving water quality, biological, and physical data and is used by state environmental agencies, EPA and other federal agencies, universities, private citizens, and many others. Similarly, state environmental agencies and the U.S. Geological Service (USGS) also have water quality data available that, in some instances, can be accessed online. "Legacy STORET" codes for hardness include: 259 hardness, carbonate; 260 hardness, noncarbonated; and 261 calcium + magnesium, while more recent, "Modern STORET" data codes include: 00900 hardness, 00901 carbonate hardness, and 00902 noncarbonate hardness; or the discrete measurements of calcium (00915) and magnesium (00925) can be used to calculate hardness. Hardness data historically has been reported as "carbonate," "noncarbonate," or "Ca +Mg." If these are unavailable, then individual results for calcium (Ca) and magnesium (Mg) may be used to calculate hardness using the following equation: mg/L CaCO 3 = 2.497 (Ca mg/L) + 4.118 (Mg mg/L)When interpreting the data for carbonate and non-carbonate hardness, note that total hardness is equivalent to the sum of carbonate and noncarbonate hardness if both forms are reported. If only carbonate hardness is reported, it is more than likely that noncarbonate hardness is absent and the total hardness is equivalent to the available carbonate hardness.Stormwater Discharges Associated With Industrial Activity -Appendix J J-3 General Permit Appendix K No Exposure Certification Form Stormwater Discharges Associated With Industrial Activity -Appendix K K-1 NPDES UNITED STATES ENVIRONMENTAL PROTECTION AGENCY Form Approved FORM WASHINGTON, DC 20460 OMB No. 2040-0211 3510-11 NO EXPOSURE CERTIFICATION FOR EXCLUSION FROM NPDES STORMWATER PERMITTING Submission of this No Exposure Certification constitutes notice that the entity identified in Section A does not require permit authorization for its stormwater discharges associated with industrial activity in the State identified in Section B under EPA's Stormwater Multi Sector General Permit due to the existence of a condition of no exposure.A condition of no exposure exists at an industrial facility when all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snowmelt, and/or runoff. Industrial materials or activities include, but are not limited to, material handling equipment or activities, industrial machinery, raw materials, intermediate products, by-products, final products, or waste products. Material handling activities include the storage, loading and unloading, transportation, or conveyance of any raw material, intermediate product, final product or waste product.A storm resistant shelter is not required for the following industrial materials and activities: -drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak. "Sealed" means banded or otherwise secured and without operational taps or valves;-adequately maintained vehicles used in material handling; and-final products, other than products that would be mobilized in stormnwater discharges (e.g., rock salt).A No Exposure Certification must be provided for each facility qualifying for the no exposure exclusion. In addition, the exclusion from NPDES permitting is available on a facility-wide basis only, not for individual outfalls. If any industrial activities or materials are or will be exposed to precipitation, the facility is not eligible for the no exposure exclusion. By signing and submitting this No Exposure Certification form, the entity in Section A is certifying that a condition of no exposure exists at its facility or site, and is obligated to comply with the terms and conditions of 40 CFR 122.26(g).

The cause for the oil spill was improper assembly of the connection between the flush hose sections.November 2000 In November 2000,. a leak was discovered in the underground fuel supply line from the Auxiliary Boiler Fuel. Oil Tank. The tank and steel fuel lines were None 7 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC installed in 1977. Excavation of the fuel line revealed a'A-inch hole in the four-inch supply line to the Auxiliary Boiler. The fuel line was immediately repaired.Contaminated soil was removed prior to replacement of both 1,200-foot sections of the fuel-line and return line during the summer of 2001. This replacement was accomplished by inserting a new line inside the old lines.The results of the Site Investigation, which included soil borings and monitoring wells, indicated that no residual source of oil was present. Concentrations of contaminants, in groundwater (specifically MTBE) at levels slightly greater than the ambient groundwater quality standards remain. Groundwater sampling, as directed by NHDES, continues in this location.March 2001 In March 2001, a leak was discovered in the underground None.-gasoline and diesel fuel lines at the Vehicle Maintenance Shop. This 40-foot long piping system was installed in 1993 and consisted of two-inch diameter pipes with a corrosion protection wrapping. The fuel release did not impact surface waters either directly or via the storm drainage system. Contaminated soil was removed prior to installation of a new pump station. A Site Investigation including soil borings and monitoring wells was performed. Groundwater samples obtained to-date indicate that concentrations of gasoline-related compounds continue to show a decreasing trend with no VOCs other than MTBE detected at levels above the ambient groundwater quality standards: Groundwater monitoring is ongoing.The site Spill Prevention Control and Countermeasure (SPCC) Plan (Reference 3.4) contains a full description of the historical large oil spills on site.2.3 Non-Stormwater Discharges Documentation The presence of non-storm water discharges was evaluated in two phases both of which where completed during 1993-1994. Phase I involved a plant schematic review and Phase II verified the review with a visual inspection of the drains. Power plant effluents and a large part of the Seabrook Station site (Subarea A) discharge into the storm drain system that in turn discharge into the Circulating Water System (at Manhole 34). The discharge of the Circulating Water System (Outfall 001) is controlled and monitored under the NPDES Permit.8 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC The Station Drain Table Reference (Reference 3.3) lists the results of the evaluation and includes those drains (roof, floor, equipment, etc.) that discharge directly to the storm drain system.Excluded are those drains that firstdischarge to a NPDES-monitored outfall, such as an oil/water separator, before discharging to the storm water drain system. Reference 3.3 also includes the drain type, any contaminants in the vicinity, the type of BMP in place, and the likelihood of a-material release causing storm water pollution. Attachment B contains a certification of the results.Other non-storm water discharges include* Fire hydrant flushing* Potable water sources, including waterline flushings* Air conditioning condensate

• Discharges from naturally occurring streams* Routine exterior building wash down that does not use detergents or other compounds Pavement wash waters where detergents are not used and where leaks or spills of hazardous materials have not occurred* Dewatering of building groundwater inleakage* Dewatering operations that may occur during the performance of construction activities The locations of the discharges described above occur throughout Seabrook Station and are too numerous to individually identify in Figure 5. These discharges may be made to New Hampshire surface waters either through Outfall 001 or directly via sheet runoff. Each is administratively controlled either by procedures or routine inspection.

All dewatering operations are administratively controlled and include the following:

1. Discharge of ground water to New Hampshire Surface Waters 2. Return of ground water. to the ground without a discharge to New Hampshire Surface Waters 3. Removal of storm water that has collected on site Case 1: The routine discharge of groundwater to NPDES Permit Outfall 001 (ocean discharge) is described in the documentation that supports the renewal of Seabrook Station's NPDES Permit (effective April 2002).Dewatering of several plant buildings (Containment Annulus, Primary Auxiliary Building, Yard Equipment Vaults and Fuel Storage Building) may contain small amounts of radioactive tritium.9 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC The groundwater dewatering system discharges directly to the storm drain system which flows via Manhole 34 in the Circulating Water System Junction Box Wet Weather Discharge to Outfall 001 (Ocean Discharge).

Radioactive discharges are addressed in Seabrook Station's NPDES Permit Part I.A. 10 for Outfall 001 (ocean discharge), which states that the discharge of radioactive materials shall be in accordance with the Nuclear Regulatory Commission (NRC) requirements (10 CFR 20 and the Seabrook Station Operating License, Appendix A, Technical Specifications). The following guidance is used in determining the requirements for the discharges of groundwater to Outfall 001: 1. If the groundwater is being removed from an area that has no history of soil contamination, measures shall be taken to avoid the discharge of silt.The effluent shall also be inspected for an oil sheen or odor, which are indications of oil or chemical contamination. If there is an indication of contamination, the discharge must be terminated.

2. If the groundwater is being removed from an area that has a potential history of soil contamination or known history of soil contamination, such as areas near the Vehicle Maintenance Facility or Auxiliary Boiler fuel line, then a Temporary Surface Water Discharge Permit will be acquired from the New Hampshire Department of Environmental Services and the Environmental Protection Agency in accordance with Env-Ws 1505. This permit will specify the water discharge parameters, treatment methods, water quality sampling requirements and reporting requirements.

Case 2: Groundwater may be returned to the ground if it does not reach surface waters such as the surrounding wetlands and may proceed using the following guidance: 1. If the groundwater is being removed from an area that has no history of soil contamination, the water can be returned to the ground and allowed to percolate into the ground provided none of the water runs off into a surface water. The groundwater shall be inspected for an oil sheen or odor, which are indications of oil or chemical contamination. If there is an indication of contamination, the discharge must be terminated.

2. If the groundwater is being removed from an area that has a potential.

history of soil contamination or known history of soil contamination, the New Hampshire Department of Environmental Compliance Groundwater Protection Bureau must be contacted prior to discharging the effluent back ,to the ground.Case 3: Storm water from precipitation is an expected discharge to Outfall 001 or nearby wetlands. Therefore, if a depression or excavation contains known storm water, it can be returned directly to the ground or can be routed to Outfall 001. The discharge of silty water should be avoided.10 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC 2.4 Salt Storage 1. North of Furniture Storage Building (Ref. 48) -Covered Structure 2. West End of Clorination Building (Ref. 45) -Covered Structure 2.5 Sampling Data Summary See Attachment C for summary of all stormwater samples collected. 11 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC SECTION 3: STORMWATER CONTROL MEASURES 3.1 Minimize Exposure The SWPPP uses the following measures and controls as standard Best Management Practices (BM Ps).3.2 Good Housekeeping The Maintenance Manual (Reference 3.10) requires that personnel practice basic good housekeeping methods. These include operation practices, material inventory practices, and material storage practices. These practices are identified, performed, and reviewed through the work order system (Reference 3.8), which establishes the administrative controls for repetitive tasks. Where practicable, large dumpsters for trash or industrial materials have covers to prevent exposure to precipitation.

3.3 Maintenance

Station preventive maintenance uses the Repetitive Tasks system as well as department procedures to provide timely inspection and maintenance of storm water management devices.The tasks include maintenance of oil/water separators. Catch basins are cleaned periodically on an as-needed basis to remove sand and silt.3.4 Spill Prevention and Response Seabrook Station maintains the Spill Prevention Control and Countermeasure (SPCC) Plan and the Oil and Hazardous Substances Pollution Contingency Plan. Together, these plans identify potential oil and hazardous materials pollution sources, provide physical structures and systems to prevent discharge, and the resources (both personnel and equipment) available to implement cleanup if it is needed.12 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC 3.5 Erosion and Sediment Controls Various sediment and erosion control measures have been implemented. These include road paving and traffic control; regular street sweeping and catch basin maintenance; grading, seeding, and construction of diversion structures. In addition, regular Licensing Department Surveillances are conducted (see §5.3.4).3.6 Management of Runoff Two routine inspection programs are conducted by site personnel to review designated equipment and areas for leaks and potential sources of pollution. These include: Nuclear Systems Operator routine inspections of Station-related equipment and areas.Licensing Department surveillances and inspections of the nonradiological aspects of the Environmental Compliance Program. Licensing personnel perform routine quarterly environmental surveillances of the Seabrook Station site and initiate a corrective action program document (Condition Report) as necessary. The purpose of these broader environmental inspections is to identify and correct items which are not in compliance with applicable environmental regulations or site policies and procedures. These items include leaks from tanks, equipment, transformers or stored materials including chemicals or compressed gases, erosion, and debris.The quarterly inspections of the site are performed in accordance with the Licensing Department-Site Environmental Surveillance Instruction (ENV-4).Deficiencies in implementation of the Storm Water Pollution Prevention Plan identified during these inspections are corrected within 14 days of discovery in accordance with the Storm Water Multi-sector General Permit.3.7 Salt Storage Piles or Piles Containing Salt Sand mixed with salt is used on site roads and walkways for deicing. The sand/salt is stockpiled in the former Hazardous Waste Facility structure west of the Production Warehouse (Figure 5).A smaller storage area is located at the west end of the Clorination Building.The following are Best Management Practices for Sand and Salt issued by NH DES: 13 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC (The BMPs will be complied with to the extent practical with consideration given to the environmental risk posed b, the storage location and features of the structure.) All salt and sand/salt mixtures should be stored on pads of impermeable asphalt or concrete. Storage and loading areas should have an impermeable floor constructed of asphalt, concrete, or other suitable material that extends around the building and work area exterior. The area should be sloped away to prevent stormwater from entering the loading areas or structure.

• Concrete pads and walls should be treated to prevent concrete deterioration (spalling).
• Structure hardWare should be galvanized and concrete block buildings should be waterproofed inside.* If using a three-sided building, the exposed salt at the open end should be covered. The sand/salt should be maintained within the confines of the structure.
• Stormwater and snowmelt runoff should be properly controlled.

Building floors and storage pads should be sloped to prevent ponding and allow any water to drain away from the storage piles.3.8 MSGP Sector-Specific Non-Numeric Effluent Limits Does not apply to Nuclear Utility.3.9 Employee Training Seabrook Station maintains the Training and Qualification Program to identify training needs (Reference 3.14). All station personnel, including contractors, receive environmental awareness training. In addition, every employee receives annual Plant Access Training (PAT), which addresses topics such as spill identification and response, good housekeeping, and material management practices. Station personnel, Whose work involves significant environmental aspects, receive specialized training to minimize impacts (Reference 3.13). For instance, Fire Brigade personnel receive training as primary responders to hazardous material spills or releases. In addition, a Spill Event 14 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC Response Team (SERT) is trained in the control and cleanup of oil and hazardous material spills, including the use of equipment maintained on site (see Reference 3.4).3.10 Non-Stormwater Discharges Reference Section 2.3 3.11 Waste, Garbage and Floatable Debris Trash is disposed in dumpsters staged in the vicinity of selected site buildings. A central trash disposal area has also been established on the southern side of Rocks Road in the ."G" parking area. This area has three roll-off style dumpsters for trash, metal and wood. A trash hauler and metal recycling vendor periodically remove the dumpster contents. The central area is periodically surveyed to ensure good housekeeping and proper disposal of authorized materials. 3.12 Dust Generation and Vehicle Tracking of Industrial Materials Construction projects having the potential to generate significant dust will incorporate measures to control the amount generated. Generally surface wetting will be used as the primary control mechanism. Construction projects will also consider the potential for industrial material to be tracked away from the construction area by vehicles. Control measures such as pressure washing vehicles when exiting the construction area will be used as required.15 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC SECTION 4: SCHEDULES AND PROCEDURES FOR MONITORING Benchmark Effluent State or Tribal Other(as Monitoring (2008 Limitations Specific Impaired Waters required by EPA MSGP, Part Guidelines Monitoring 2008 MSGP Part 6.2.1)* Monitoring Monitoring 6.2.5)Storm Drain Rad Reference Sample Monitor and Procedure CP n/a n/a, n/a Locations North Road Delivery Access Pollutant Reference Parameters to Total Iron Procedure CP n/a n/a n/a be sampled 9.1 Figure 5.1 4 quarterly Monitoring samples that Reference Schedule averaged do not Procedure CP n/a n/a n/a exceed 9.1 Figure 5.1 benchmark Numeric Reference 1.0 mg/L Procedure CP n/a n/a n/a 9.1 Figure 5.1 Reference Procedures ENVSa SWPPP Procedure CP n/a n/a n/a Sampling 9.1 Figure 5.1*Benchmark data will be located underAttachment C of SWPPP SECTION 5: INSPECTIONS Routine Facility Quarterly Visual Comprehensive Site Inspections (2008 MSGP, Assessment of Stormwater Inspection (2008 MSGP, Part 4.1) Discharges (2008 MSGP, Part 4.3)Part 4.2)Responsible Dept Environmental Dept.

Regarding Historic Properties Industrial facilities are eligible for coverage under the Storm Water Multi-sector General Permit (MSGP) if their storm water discharges do not affect a property that is listed or is eligible for listing on the National Register of Historic Places (per MSGP Section 1.2.3.7).- The following information documents the basis for Seabrook Station's eligibility for coverage under the MSGP with respect to historic places. Seabrook Station's storm water discharges and non-storm water discharges do not have the potential to affect property that is either listed or eligible for listing on the National Register of Historic Places since no historic properties are located in the vicinity of the locations where storm water discharges reach the receiving waters that includes the surrounding salt marsh and Atlantic Ocean. This condition meets the MSGP Addendum B Eligibility Criteria 1.A review of the National Park Service National Register of Historic Places website (http://www.nr.nps.gov/) for Rockingham County, New Hampshire identified no historic places in the Town of Seabrook. Several Historic Places were identified in the adjoining towns of Hampton and Hampton Falls. However, none of these historic places are in the path of Seabrook Station's storm water and non-storm water discharges or where construction activities may be planned to install best management practices (BMPs) to control such discharges.

6.3 Documentation

Regarding NEPA Review (if applicable) This requirement is not applicable to Seabrook Station. Seabrook Station does not discharge stormwater that is subject to New Source Performance Standards stormwater-specific effluent limitations guidelines (ref; Section 1.1.2.5 of General Permit and Table 1-1) thus there is no NEPA review documentation. 17 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC SECTION 7: SWPPP CERTIFICATION I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted.

This revision was necessary because the Storm Water Pollution Prevention Plan is no longer a requirement of the renewed NPDES Permit (effective as of April 1, 2002). In general, the contents of the Storm Water Pollution Prevention Plan were reordered to match MSGP requirements or expanded to add requirements not otherwise addressed previously. Specific major changes are as follows: Quarterly visual monitoring of storm water discharges is now required to assess potential pollutant inputs. Previously, analytical samples were taken for pH, oil and grease and total suspended solids.These pollutants will now be assessed visually. The only parameter measured now in storm water discharges will be total iron.A new attachment was added -- Endangered Species and Historic Places Assessment, which shows that Seabrook Station's storm water discharges will not impact endangered species or historic buildings. 22 Stormwater Pollution Prevention Plan (SWPPP)NextEra Energy Seabrook, LLC SWPPP ATTACHMENTS Attachment A -General Location Map Attachment B -Site Map Attachment C -Sampling Data Summary Attachment D -Endangered Species and Historic Places Assessment Attachment E -2008 MSGP 23 The State of New Hampshire DEPARTMENT OF ENVIRONMENTAL SERVICES Thomas S.

INEXTera" ENEFRGY4 July 15, 2010 SBK-L-10132 State of New Hampshire Department of Environmental Services PO Box 95 Concord, NH 03302-0095 Attention: Stephanie Larson Wastewater Engineering Bureau Seabrook Station Response to Letter of Deficiency -NPDES Compliance Evaluation Inspection (CE])NextEra Energy Seabrook, LLC, has enclosed responses to the two deficiencies identified in Letter of Deficiency WD WWEB/C 10-002. The subject NPDES Compliance Evaluation Inspection was conducted on June 3, 2010 at Seabrook Station (NPDES Permit NH0020338). If you have questions on this matter, please call Allen Legendre, Principal Engineer, at (603) 773-7773.Sincerely, NextEra Energy Seabrook, LLC Michael O'Keefe/Licensing Manager NextEra Energy Seabrook, LLC, P.O. Box 300, Lafayette Road, Seabrook, NH 03874 ENCLOSURE TO SBK-L-10132 Response to Letter of Deficiency WD WWEB/C 10-002 NPDES Compliance Evaluation Inspection (CEI)June 3, 2010, Seabrook Station (NPDES Permit N110020338) DEFICIENCY: (Response Required)1) Part II, Section B.1. of Seabrook Stations's NPDES permit requires proper operation and maintenance of all facilities and systems of treatment necessary to achieve compliance with the permit. Proper operation and maintenance includes adequate laboratory controls and appropriate quality assurance procedures. As discussed in Stephanie Larson's May 17, 2010, email to Seabrook Station and during the CEI, Seabrook Station must submit a Quality Assurance/Quality Control (QA/QC) Manual to DES for review and approval.Copies of the NHDES Wastewater Laboratory QA Program Guidelines and the US EPA NPDES Compliance Inspection manual are available on the N[HDES website.NextEra Energy Seabrook Response: The Seabrook Station procedure for the NPDES Permit QA/QC requirements, CD0923.24"NPDES Quality Assurance/Quality Control Procedure", was not submitted for NI-DES review as was recommended in the previous CEI report (September 2008). Subsequent to the September 2008 CEL, in accordance with the inspector's recommendation, changes were made to two Chemistry Department procedures to update references to EPA approved analytical methods.The effected procedures were CN0923.01 "NPDES -pH" and CN0923.05 "NPDES -Total Residual Oxidant by Amperometric Titration". The inspector's recommendation to submit the QA/QC procedure to NHDES was not completed as there was no tracking item for the action to do so. Our corrective action program should have been used to track the action to submit the QA/QC procedure to NHDES but was not used for an indeterminate reason.NextEra Energy Seabrook requests an additional 60 days from the date of this letter to submit procedure CD0923.24 to NHDES. The requested additional time will allow us to make changes to the procedure that may be necessitated by our review of the current revisions of the NHDES Wastewater Laboratory QA Program Guidelines and the US EPA NPDES Compliance Inspection Manual. The procedure will be submitted by September 13, 2010.Additionally, understanding that NHDES is required to periodically review permitee QA/QC manuals a task will be established in our work management system to routinely review the procedure for any needed updates and to submit the procedure to NHDES for review. The frequency for this task will be set at 48 months. We will provide written confirmation by September 13, 2010, that this work task has been created. REPEAT DEFICIENCY: Noted in the October 6, 2005 and September 18, 2008 Inspections (Response Required)1) Seabrook Station has not been completing its DMRs according to EPA's DMR instructions. DES' monthly compliance database report for the period of January through December 2009 was reviewed with the facility during the inspection. Seabrook Station had DMR violations in 3 of the 12 months reviewed. Corrected DMRs have been submitted. It should also be noted that DMR errors have occurred each year since 2004. A copy of DES'monthly compliance database report from January 2004 through April 2010 was left with facility personnel. As Seabrook Station is certifying that the DMR information provided is true, accurate, and complete, more attention must be paid to the accuracy of this information. NextEra Energy Seabrook Response: The deficiency statement is correct that a lack of attention to detail is the cause for the identified DMR violations. The personnel responsible for DMR preparation and review did not adequately use institutionalized error prevention techniques which would have precluded the DMR violations. The expectation to use established error prevention techniques in conjunction with the preparation and review of DMRs will be reinforced with the responsible personnel by July 30, 2010. To further ensure thorough DMR preparation and review the Chemistry Department procedure for DMR preparation CN0923.11 will be revised to add a checklist specifying the attributes for review of DMRs. The checklist will require DMR preparer and reviewer signatures and will be filed with the monthly DMR documentation. The checklist will be added to procedure CN0923.11 by August 30, 2010.NextEra Energy Seabrook also believes that utilization of the electronic DMR submission software, NetDMR, currently available on a voluntary basis to state permitees will aid in the submittal of complete DMRs. It is our intent to obtain the prerequisite training offered by EPA and to transition to electronic DMR submission prior to March 31, 2011.
