==1.0 INTRODUCTION== | |||
1.1 The purpose of the Grand Gulf Nuclear Station (GGNS) Storm water Pollution Prevention Plan is to minimize storm water contamination and identify potential pollution sources.1.2 Items in this plan requiring periodic evaluation during the year are described in Sections 4.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, Attachment IV and Attachment V.2.0 SITE DESCRIPTION 2.1 The Updated Final Safety Report [UFSAR] figure 2.4-1 shows GGNS site property boundaries. | |||
The GGNS site covers approximately 2100 acres and borders the Mississippi River.2.2 The site consists of office buildings, employee parking areas, a nuclear power generating station, industrial shop areas, laydown areas, waste accumulation areas, wastewater holding ponds, and storage tanks containing oil or chemicals. | |||
2.3 Activities at site primarily involve electrical generation and transmission. | |||
3.0 FACILITY DRAINAGE 3.1 UFSAR figures 02.4-007 and 2.4-8 shows the GGNS site drainage. | |||
Figure 1 shows building locations. | |||
3.2 Of relevance to the GGNS site are two small and steep gradient streams.The north stream (Stream A) is perennial with the south stream (Stream B)being intermittent. | |||
Storm water from the GGNS site enters one of these streams before reaching Hamilton Lake and the Mississippi River.GGNSSWPP (REV 13) -3 4.0 POLLUTION PREVENTION TEAM 4.1 The designated Storm Water Pollution Prevention Manager at GGNS is: a. Richard A. Scarbrough | |||
-Chemistry Superintendent 4.2 Designated Storm water Pollution Prevention committee members at GGNS consist of the following: | |||
: a. Ricky Buckley -Sr. Project Manager (Corporate) | |||
: b. Rusty Shaw -Chemistry Specialist | |||
: c. John Lassetter-Chemistry Supervisor 4.3 These individuals ensure that the plan is implemented as required by the general permit and are responsible for the annual inspection and any subsequent revisions needed to the plan.5.0 ASSESSMENT OF POTENTIAL STORM WATER POLLUTION SOURCES 5.1 Although there are some significant materials such as metallic products exposed to storm water at the site, there are no significant materials such as process chemicals, raw materials, fuels, pesticides or fertilizers, exposed to storm water at GGNS.5.2 Water treatment chemicals and petroleum products are stored in tanks, bins and drums. Tanks have secondary containment, while drums and bins are sealed unless in use. Therefore, exposure to storm water is not possible unless there is a leak or spill.5.3 Attachment I, Regulated Areas of Industrial Activity, lists industrial areas that are present at the GGNS site and identifies the types of potential pollutants present.6.0 RISK IDENTIFICATIONIPOTENTIAL POLLUTANT | |||
==SUMMARY== | |||
6.1 Since no manufacturing or chemical production occurs at GGNS, the areas judged to have a reasonable potential for adding pollutants to storm water are: GGNSSWPP (REV 13) -4 | |||

Jim Kegerreis 601-437-2348 Contractor: | |||
TBD GGNSSWPP (REV 13) -37 Enercon or their sub-contractors retain ultimate responsibility for determining the proper erosion control methods. Controls should, at a minimum, be in accordance with the standards set forth in "Planning and Design Manual for the Control of Erosion, Sediment and Storm Water" or other recognized manual of design as appropriate for Mississippi. | |||
The planning and design manual can be obtained by contacting MDEQ at 601-961-5171 or may be found electronically at Mississippi State's educational website at http://abe.msstate.edu/csd/p-drn/. | |||
In addition, Mississippi's "Storm Water Pollution Prevention Plan (SWPPP) Guidance Manual for Construction Activities" is available by calling MDEQ at 601-961-5171 or on the MDEQ website at www.deq.state.ms.us. | |||
These erosion controls shall address the following minimum components: | |||
Vegetative Practices shall be designed to preserve existing vegetation where possible and re-vegetate disturbed areas as soon as practical after grading or construction. | |||
Such practices may include surface roughening, temporary seeding, permanent seeding, mulching, sod stabilization, vegetative buffer strips, and protection of trees.Structural Practices shall divert flows from exposed soils, store flows or otherwise limit runoff from exposed areas. Such practices may include construction entrance/exit controls, straw bale dikes, silt fences, earth dikes, brush barriers, drainage swales, check dams, subsurface drains, pipe slope drains, level spreaders, drain inlet protection, outlet protection, detention/retention basins, sediment traps, temporary sediment basins or equivalent sediment controls.Post Construction Control Measures shall be installed to control pollutants in storm water after construction is complete. | |||
These controls include, but are not limited to, on-site filtration of run off, flow attenuation using open vegetated swales, exfiltration trenches and natural depressions, constructed wetlands and retention/detention structures. | |||
Where needed, velocity dissipation devices shall be placed at detention or retention pond outfalls and along the outfall channel to provide non-erosive flow.PROJECT SCOPE: The construction of roads and maintenance of equipment storage areas including the limited removal of trees and the construction of unpaved access roads for the placement of geological/geotechnical test wells, bore holes and test pits. The total acreage that will be disturbed is conservatively estimated at 3.5 acres. The majority of these activities will take place west and south of the existing Protected Area (PA) perimeter. | |||
GGNSSWPP (REV 13) -38 EROSION AND SEDIMENT CONTROLS: Primary potential impacts involve the construction of test pits, access roads in upslope areas, steep or unstable slopes, and the removal of trees in the immediate test areas, as required. | |||
Note that these areas have been previously disturbed by either silvacultural or previous construction activities and efforts will be made to utilize the existing old access[logging] | |||
roads, where possible.Other test areas include stabilized existing parking lots, paved roadways, and construction laydown areas minimizing potential surface water runoff impacts related to these sampling activities. | |||
After testing is completed, access roads and similar disturbed areas will be re-vegetated to minimize future potential erosion impacts.The construction of access roads and the temporary storage of vehicles and testing equipment, such as drilling pipe, are anticipated to have a similar or less impact than those activities typically observed during small scale silvacultural and construction operations. | |||
As mentioned, much of the testing occurs in areas already stabilized and maintained at grade on property primarily covered either by concrete, asphalt or gravel. Draining for these areas is provided by concrete ditches, spillways and catch basins that enter into an unnamed tributary that traverses GGNS property and enters into a sedimentation basin and eventually Hamilton Lake. This tributary is far enough removed from the test access areas to preclude any significant impacts on riparian trees or buffer zones. Storm drains located in the vicinity of these areas also enter directly into a sedimentation basin through National Pollutant Discharge Elimination System [NPDES] Outfall 007. Based upon previous similar testing activities, storm water impacts upon Outfall 007 will be negligible. | |||
Storm drains in the vicinity of any test locations may be temporarily covered or otherwise secured to preclude any impact.The sedimentation basins were excavated during construction of the GGNS facility and were originally designed to slow the flow of storm waters and allow sediments from construction activities to settle out of solution before entering State waters. Although the sedimentation basins have not been maintained to original design specifications they are still functional and provide additional protection by ponding runoff in these controlled areas.The following controls will also be implemented, as required, to retain sediment on site: Disturb the smallest area possible by using existing access routes when possible.GGNSSWPP (REV 13) -39 Strategically place silt fencing, hay bales, or other barriers as needed to filter and slow storm water runoff.If required, temporarily cover storm drains to eliminate point sources of contamination. | |||
Use hay bales, silt fencing, berms or other engineering controls to slow rainfall runoff velocities and prevent erosive flows.Minimize the amount of cut and fill.NON-STORM WATER DISCHARGES: | |||
Non storm water discharges are regulated by the GGNS NPDES Permit. Contact Chemistry for approval before discharging any non-storm water.NATIONAL HISTORICAL PRESERVATION ACT: The Grand Gulf Nuclear Station was originally evaluated by the Mississippi Department of Archives and History during the construction of the facility. | |||
This evaluation determined that operation of the station will not result in any impact on historic and archaeological sites in the area [Draft Environmental Statement, United States Regulatory Commission, May 1981, Page 5-7; Final Environmental Statement, United States Regulatory Commission, September 1981, Page 5-7).NOTE Work orders and procedures must include cultural resource specific written directions for excavation and backfill work which calls for an immediate stop-work order should archeological, historical, or other cultural resources be uncovered during excavation. | |||
The construction supervisor is responsible for ensuring work stoppage and for notifying the Environmental Lead* of an inadvertent discovery. | |||
In the event of an inadvertent discovery the Environmental Lead* will determine the inadvertent discovery's significance and if necessary, notify the State Historic Preservation Officer to consult with them regarding the discovery to determine if an additional archeological assessment is needed.* Environmental Leads: Rusty Shaw 601-437-7312 John Lassetter 601-437-2115 GGNSSWPP (REV 13) -40 HOUSEKEEPING PRACTICES: | |||
GGNS requires the following housekeeping practices to minimize contamination of storm water: Equipment Maintenance and Repair: Major equipment repairs will be conducted at the Vehicle Maintenance Shop or offsite by the vendor.Minor field repairs may be performed provided that precautions are taken to assure fuel or oil does not contaminate the ground or storm water.These precautions include the use of drip pans, containment devices that are impervious to oil or fuel, absorbent pads and/or booms or other devices as required.In addition, vehicle and equipment maintenance activities should not be performed outdoors during periods of precipitation. | |||
The equipment should be relocated, if possible, to an area that provides adequate protection from precipitation. | |||
In emergency situations a shelter may be improvised to shield the equipment from precipitation provided that controls are implemented to prevent the contamination of surface storm water runoff.Concrete Chute Wash Off: A holding pond must be excavated in a laydown or other area sufficient in size and volume to contain the concrete residue and rinse waters from cement delivery trucks plus additional freeboard to assure that these waters are not mixed and/or discharged with storm water. No other washing will be authorized. | |||
Waste Receptacles: | |||
Waste receptacles such as dumpsters, roll-off boxes and similar devices should be placed at convenient locations. | |||
Waste should be regularly collected and disposed of and not allowed to accumulate or overflow containers. | |||
In addition, workers should police access, testing, and construction areas to assure that trash and debris does not contaminate or is not removed by storm water run off.Chemical Use and Storage: All chemicals must be approved by the Site Chemical Control Coordinator before they are brought on site. After approval each chemical container must retain the proper label(s), including the chemical control label, and be properly stored as directed by the Site Chemical Control Coordinator and in accordance with site safety and fire protection requirements. | |||
GGNSSWPP (REV 13) -41 Chemicals may not be left unattended. | |||
When chemicals are not in use they must be properly secured and stored.Protective clothing requirements are prescribed by GGNS Industrial Plant Safety.All personnel, including contractors are required to comply with the appropriate GGNS procedures and expectations at all times.Sanitary Facilities: | |||
Sanitary facilities are located at various locations. | |||
If these are not sufficient portable facilities must be provided that are in good structural condition and routinely serviced.Secondary Containment: | |||
The storage of fuel and oil is governed by the GGNS Spill Prevention Control and Countermeasures Plan [SPCC]. Temporary fuel and oil storage as well as restrictions on draining water from containment devices must comply with the requirements of this plan.Temporary fuel and oil containers must have containment of sufficient volume to contain their contents plus 10% additional freeboard. | |||
These must also be located in areas where they are protected from damage by vehicular traffic [Review the appropriate Environmental Regulatory Review for more detailed information]. | |||
In addition, temporary equipment not in use must also be provided with containment unless equipped with double walled tanks, skid pans or other devices capable of containing the entire contents of the tank.Water may not be discharged from containment devices if there is a visible sheen or other evidence of contamination. | |||
Contact Chemistry for additional guidance prior to discharging potentially contaminated water from containment devices.Releases of Fuel, Oil or other Substances: | |||
Any spill, regardless of the volume, must be immediately reported to the Control Room [X2374 or Radio Channel 11. The control room will dispatch trained HAZMAT responders if necessary. | |||
If possible, spills should immediately be controlled so they do not mix with storm water or pose a threat to state waters.GGNSSWPP (REV 13) -42 All spills must be promptly cleaned and contaminated sediments removed.Chemistry will provide guidance for the remediation of spills and for the disposal of associated waste materials. | |||
GGNS Chemistry evaluates all spills to determine reportability and the need to contact Federal or State regulatory officials. | |||
Verify that Chemistry has been contacted and is aware of the spill.Chemistry contacts are: Supervisor: | |||
John Lassetter 601-437-2115 Staff: Rusty Shaw 601-437-7312 GGNS procedures and expectations also require that all spills are documented by the Control Room using the Spill Report Form and that the incident is documented using a Condition Report [CR].Scaled Site Map: See maps on page 45 and 46.Implementation Sequence: Necessary erosion and sedimentation controls described in this plan will be implemented before any construction activities begin: " Implementation of the testing and associated construction/clearing activities will begin April 1, 2006." These activities will be concluded approximately August 1, 2006.Limitations and Requirements: | |||
The limitations and requirements specified in the MDEQ Small Construction General Permit are included in Appendix A. Please note the following additional comments: Inspection Requirements | |||
[Part IV; Item Cl: Inspections are performed by the person having direct management oversight of the project, or responsible designee, who retains the ability to maintain or modify existing erosion controls or implement additional controls as required. | |||
Chemistry makes independent inspections and verifications of compliance including suggestions and recommendations for improving erosion controls, as needed.Retention of Records [Part IV; Item El: Original inspection forms are maintained with a copy of the SWPPP Permit by the person having direct management oversight of the GGNSSWPP (REV 13) -43 project, or responsible designee, for inspection by MDEQ. When the project is completed copies of the inspections should be transmitted to file and the originals forwarded to Chemistry to be maintained on file for inspection for three (3) years from the date construction was completed. | |||
Noncompliance Reporting | |||
[Part IV; Item F]: Chemistry transmits all regulatory reports and notifications to the proper regulatory authorities. | |||
Because a noncompliance has the real potential to result in an NPDES permit exceedance or other regulatory requirement GGNS Chemistry must immediately be made aware of any circumstances that could or do result in a noncompliance with the limitations and requirements specified in the MDEO Small Construction General Permit [Appendix A].Any noncompliance may constitute a violation of State and Federal law and may provide grounds for an enforcement action GGNSSWPP (REV 13) -44 Test Monitoring Well and Borehole Locations Note: 6 additional borings are at the proposed intake facility along the Mississippi River shoreline. | |||

I These discharges are automatically designated as small construction activities under the National Pollutant Discharge Elimination System (NPDES) storm water program and are automatically covered under this permit. Small construction activities disturbing less than one (I) acre are designated if:* The project is part of a larger common plan of development or sale with a cumulative planned disturbance of equal to or greater than one (I) acre and less than five (5) acres (for example, individual or commercial lots that are part of a subdivision or a commercial development that initially impacts less than one (I) acre but will ultimately exceed the one (l) acre threshold2), or a The Executive Director of the Mississippi Department of Environmental Quality (MDEQ) designates the construction activity based on the potential for contribution to a violation of a water quality standard or for significant contribution of pollutants to waters of the State.Small construction activity does not include routine maintenance that is performed to maintain the original line and grade, hydraulic capacity. | |||
and original purpose of the facility (for example, existing ditches, channels, or other similar storm water conveyances, as well as routine grading of existing dirt roads, asphalt overlays of existing roads, and other similar maintenance activities). | |||
C. Obtaining Authorization. | |||
Owners or operators are authorized to discharge storm water associated with small construction activity under the terms and conditions of this permit upon commencement of small construction land disturbing activities (i.e., Construction may begin after development of the required Storm Water Pollution Prevention Plan (SWPPP) and the completion of the Small Construction Notice of Intent (SCNOI)).D. On-going Construction Activities. | |||
Projects that are on-going as of March 10. 2003 and are equal to or greater than one (I) acre and less than five (5) and do not have coverage under Construction General Permit MSRIO must obtain coverage by complying with the terms and conditions of this permit.E. Allowable Non-Storm Water Discharges. | |||
Owner or operators are authorized for the following non-storm water discharges. | |||
Except for flows from fire fighting activities, sources of non-storm water below that are combined with storm water discharges associated with construction activity must be identified in the Storm Water Pollution Prevention Plan (SWPPP). The SWPPP must identify and ensure the implementation of appropriate pollution prevention measures for the non-storm water component(s) of the discharge." Discharges from fire-fighting activities" Fire hydrant flushings" Waters used to wash vehicles where detergents are not used" Water used to control dust" Potable water sources including water line flushings" Routine external building wash down that does not use detergents" Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred (unless all spilled material has been removed) and where detergents are not used" Uncontaminated air conditioning or compressor condensate" Uncontaminated ground water or spring water" Foundation or footing drains where flows are not contaminated with process materials such as solvents 1 This includes the total area disturbed over the course of the project. For home sites -a minimum of 10,000ft2 per home site or the entire lot, if smaller, shall be included.2For subdivision development, if the total acreage disturbed for the entire development is 5 acres or greater then all lots are covered by Mississippi's Storm Water Construction General Permit for construction activity over 5 acres (Large Construction). | |||
GGNSSWPP (REV 13) -50 F. Responsibility for Permit Compliance. | |||
The owner(s) of the property and any operator(s) associated with small construction activity on the property shall have joint and several responsibility for compliance with this permit.G. This Permit Does Not Authorize: " Discharges of hazardous substances or oil. This permit does not authorize the discharge of hazardous substances or oil resulting from an on-site spill." Post Construction Discharges. | |||
This permit does not authorize storm water discharges that originate from the site after construction activities have been completed and the site has undergone final stabilization." Discharges Covered by Another Permit. This permit does not authorize storm water discharges associated with construction activity that have been covered under an individual permit in accordance with Part I.H. of this permit." Discharges Threatening Water Quality. This permit does not authorize storm water discharges from construction sites that the Executive Director determines will cause, or have reasonable potential to cause or contribute to, violations of water quality standards. | |||
Where such determinations have been made, the Mississippi Environmental Quality Permit Board (Permit Board) may notify the owner or operator that an individual permit application is necessary in accordance with Part I. H. of this permit. However, the Permit Board may authorize coverage under this permit after appropriate controls and implementation procedures designed to bring the discharges into compliance with water quality standards have been included in the Storm Water Pollution Prevention Plan." Discharges to Impaired Receiving Waters. The SWPPP must specifically identify Best Management Practices (BMPs) which ensure storm water will not cause or contribute to non-attainment of a water quality standard. | |||
In cases where the Permit Board becomes aware of potential impairment due to small construction activities, the Permit Board may require the submittal of the SWPPP in order to ascertain whether the selected BMPs are sufficient to comply with requirements of this permit or any other requirements of the Permit Board. The list of impaired receiving waters may be found on the MDEQ web site at www.deq.state.ms.us or by calling 601-961-5171.H. Requiring an Individual Permit Upon notification of a small construction project, the Permit Board may require an alternate permit.

Grand Gulf COL Site Activity Review Form Items: N/A 50.59 Screening Items: N/A Air Operating Permit: N/A The GGNS Air Operating Permit [Mississippi Permit No: 0420-000231 does not regulate or prescribe limitations and conditions for geotechnical/geologic investigations provided that permanent fuel burning engines are not installed to facilitate the activities. | |||
[This implements the Clean Air Act regulations referenced in EN-EV-)115; Section 2, Items 2 and 5(c).]National Pollution Discharge Elimination System Permit [NPDES]: N/A This activity will not create any new or additional discharges or the addition of any chemicals requiring either a modification to the GGNS NPDES Permit or notification to the state permitting authority. | |||
The state permitting authority independently verified this -see GTC 2006/00007 and GTC 2006/00011. | |||
[This implements the Clean Water Act regulations referenced in EN-EV-1 15; Section 2, Items 2 and 5(g).]Storm Water Permit/Plan: | |||
N/A This activity does not initially involve any construction or land disturbance in excess of 1 acre and does not add a new source of industrial activity that would require a either a Construction Notice of Intent or an amendment to the GGNS Storm Water Plan.NOTE When it is determined that land disturbances such as bulldozing, tree clearing, equipment storage, or other construction activities inclusive to this project have the potential to exceed I acre; construction work must be stopped prior to exceeding the I acre limitation until a Construction Permit is transmitted to the state permitting authority. | |||
If this work continues to expand and reaches the potential to exceed 5 acres, construction work must be stopped prior to exceeding the 5 acre limitation until the site environmental lead determines whether the state permitting authority will impose any additional requirements, such as a revised Construction Permit and the submittal of a Construction Notice of Intent.[This implements the Clean Water Act regulations referenced in EN-EV- 115; Section 2. Items 2 and 5(f). I GGNSSWPP (REV 13) -66 Spill Pollution Control and Countermeasures Plan [SPCCJ: The GGNS SPCC Plan requires any container | |||
[including non-attended vehicle fuel tanks] with a capacity(2) equal to or greater than 55 gallons to be properly stored and maintained. | |||
This means that containers for fuel, Hydraulic Fluid, Lubrication Oil, or any other oil must have containment sufficient to contain the volume of oil stored in the container plus 10% additional volume for freeboard. | |||
GGNS expects that oil/fuel containers are properly stored and managed so there are no spills onto the ground or into surface waters. Use absorbent pads or similar materials to contain and absorb fuel or oil leaks from vehicles or other equipment. | |||
Leaks and spills, regardless of volume, must be reported and documented in accordance with GGNS Administrative Procedure, 01-S-12-20, "Hazardous Materials Emergency Response Plan".Footnote (2): Capacity means the volume of the container, not the amount of material it contains. | |||
For example, the GGNS SPCC Plan regulates a 55-gallon drum containing 30 gallons of oil. The GGNS SPCC Plan does not regulate a 35-gallon drum containing 30 gallons of oil.NOTE An oil or fuel spill in an amount sufficient to cause sheen upon surface waters [navigable waters] requires a notification to the U.S. Coast Guard National Response Center and subsequently state regulatory authorities. | |||
This is also a Nuclear Regulatory Commission reportable event. All efforts must be made to properly manage and prevent any oil or oil containing material from entering a navigable waterway [For the purposes of this document these include the storm drain system, sedimentation basins, streams, Mississippi River, barge slip, barrow pits, and Gin and Hamilton lakes].[This implements the Clean Water Act regulations referenced in EN-EV- 115; Section 2, Items 2 and 5(e).)Endangered and threatened species: Although endangered species have been identified in the proximity of the Grand Gulf Nuclear Station none have been documented in the vicinity of this activity and the implementation of protective management plans is not required. | |||
The sighting of an endangered species such as an eagle or a black bear must be immediately related to the site environmental lead.

1.0 INTRODUCTION
1.1 The purpose of the Grand Gulf Nuclear Station (GGNS) Storm water Pollution Prevention Plan is to minimize storm water contamination and identify potential pollution sources.1.2 Items in this plan requiring periodic evaluation during the year are described in Sections 4.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, Attachment IV and Attachment V.2.0 SITE DESCRIPTION 2.1 The Updated Final Safety Report [UFSAR] figure 2.4-1 shows GGNS site property boundaries.
The GGNS site covers approximately 2100 acres and borders the Mississippi River.2.2 The site consists of office buildings, employee parking areas, a nuclear power generating station, industrial shop areas, laydown areas, waste accumulation areas, wastewater holding ponds, and storage tanks containing oil or chemicals.
2.3 Activities at site primarily involve electrical generation and transmission.
3.0 FACILITY DRAINAGE 3.1 UFSAR figures 02.4-007 and 2.4-8 shows the GGNS site drainage.
Figure 1 shows building locations.
3.2 Of relevance to the GGNS site are two small and steep gradient streams.The north stream (Stream A) is perennial with the south stream (Stream B)being intermittent.
Storm water from the GGNS site enters one of these streams before reaching Hamilton Lake and the Mississippi River.GGNSSWPP (REV 13) -3 4.0 POLLUTION PREVENTION TEAM 4.1 The designated Storm Water Pollution Prevention Manager at GGNS is: a. Richard A. Scarbrough
-Chemistry Superintendent 4.2 Designated Storm water Pollution Prevention committee members at GGNS consist of the following:
- a. Ricky Buckley -Sr. Project Manager (Corporate)
- b. Rusty Shaw -Chemistry Specialist
- c. John Lassetter-Chemistry Supervisor 4.3 These individuals ensure that the plan is implemented as required by the general permit and are responsible for the annual inspection and any subsequent revisions needed to the plan.5.0 ASSESSMENT OF POTENTIAL STORM WATER POLLUTION SOURCES 5.1 Although there are some significant materials such as metallic products exposed to storm water at the site, there are no significant materials such as process chemicals, raw materials, fuels, pesticides or fertilizers, exposed to storm water at GGNS.5.2 Water treatment chemicals and petroleum products are stored in tanks, bins and drums. Tanks have secondary containment, while drums and bins are sealed unless in use. Therefore, exposure to storm water is not possible unless there is a leak or spill.5.3 Attachment I, Regulated Areas of Industrial Activity, lists industrial areas that are present at the GGNS site and identifies the types of potential pollutants present.6.0 RISK IDENTIFICATIONIPOTENTIAL POLLUTANT
SUMMARY
6.1 Since no manufacturing or chemical production occurs at GGNS, the areas judged to have a reasonable potential for adding pollutants to storm water are: GGNSSWPP (REV 13) -4
- a. Vehicle Maintenance
- 1. Vehicle Maintenance Shop -Servicing of vehicles and similar industrial equipment.
This area consists of a vehicle wash rack, fuel truck containing diesel and gasoline, and intermittent industrial equipment such as trucks, cranes and portable generators.
Servicing activities occur under a covered area except for occasional crane maintenance and the fuel truck is parked within a concrete containment structure.
Storm water runoff from this area drains either to an oily water separator or a sump prior to discharge into Stream A.The pollutant of concern at this location is petroleum hydrocarbons.
- b. Vehicle Fueling 1. Vehide Maintenance Shop Fueling Area -Diesel fuel and gasoline are stored in aboveground tanks behind the Vehicle Maintenance Shop for vehicle and industrial equipment fueling purposes.
The tanks are located within a covered containment structure.
Although the potential for minor spills exists during fueling activities, runoff from this area drains to an oily water separator prior to discharge into Stream A. The pollutant of concern at this location is petroleum hydrocarbons.
GGNSSWPP (REV 13) -5
- c. Painting 1. Spray Paint Shop- The spray paint shop is located near the Energy Services Center. Spent sandblast material and metal items are stored at this area. Some spray painting is also done outside the shop. Runoff from this area drains to an open field below the shop area and does not affect water quality. The pollutants of concem at this location are iron and suspended solids.d. Site Erosion 1. Spray Paint Shop Area -The shop is located on the edge of the bluffs in an area is subject to erosion. Runoff from this area drains to an open field below the shop area and does not affect water quality. The pollutant of concern at this location is suspended solids.2. Ball field Renovation Area -Area is subject to erosion.Runoff from this area drains to a stock pond. The pollutant of concern at this location is suspended solids.3. Building and Grounds Area -The hill adjacent to this area is subject to erosion. Runoff drains into a concrete ditch prior to discharge into Sedimentation Basin A. The pollutant of concern at this location is suspended solids.4. Vehicle Maintenance Shop Area -Drainage pipes are subject to erosion. Runoff from this area drains into Stream A. The pollutant of concern at this location is suspended solids.GGNSSWPP (REV 13) -6
- 5. Stream A Storm Drains- Old Unit 2 storm water drainage pipes and flumes adjacent to Stream A are subject to erosion and no longer serve their intended purpose. These have been abandoned in place. Runoff from this area drains into Stream A. The pollutant of concern at this location is suspended solids.e. Material Unloading 1. Vehicle Maintenance Shop Gasoline and Diesel Storage Tanks -Diesel fuel and gasoline are stored in aboveground tanks behind the Vehicle Maintenance Shop. The tanks are located within a covered containment structure.
Tank unloading is associated with this location.
Although the potential for minor spills exists, runoff from this area drains to an oily water separator prior to discharge into Stream A.The pollutant of concern at this location is petroleum hydrocarbons.
- 2. Standby Diesel Fuel Generator Storage Tanks -Diesel fuel is stored in three underground tanks northwest of the Diesel Generator Building.
Since tank unloading is associated with this area, the potential for minor spills exists.Runoff from the unloading area drains to a holding tank.The pollutant of concern at this location is petroleum hydrocarbons.
- 3. Energy Services Center Diesel Fuel Storage Tank -Diesel fuel is stored in an underground tank at the Energy Services Center. Since tank unloading is associated with this area, the potential for minor spills exists. Runoff from this area drains into NPDES Outfall 016 prior to discharge into Sedimentation Basin A. The pollutant of concern at this location is petroleum hydrocarbons.
GGNSSWPP (REV 13) -7
- 4. Clean and Dirty Lube Oil Storage Tanks -Clean and dirty lube oil are stored in aboveground tanks east of the Turbine Building.
The tanks are located within a concrete berm.Since tank unloading is associated with this area, the potential for minor spills exists. The berm is manually drained into a storm drain prior to discharge into Sedimentation Basin B. The pollutant of concern at this location is petroleum hydrocarbons.
- f. Material Storage 1. Radial Well Lube Oil Storage Tanks -Lube oil is stored in aboveground tanks at the Radial Wells (Mississippi River). These tanks have secondary containment.
Should a leak occur, runoff would drain onto the ground or into the river, depending upon the river stage. The pollutant of concern at these locations is petroleum hydrocarbons.
- 2. Fire Training Area -Diesel fuel is stored in a skip pan and a portable fuel tank at the fire training area in the northwest laydown area. In addition, empty fire extinguishers and wood materials are stored at this location.
The fuel is burned in a skip pan for fire training purposes and is covered when not in use. Runoff from this area drains into an oily water separator prior to discharge into a holding pond. The pollutants of concern at this location are petroleum hydrocarbons and suspended solids.GGNSSWPP (REV 13) -8
- 3. Building & Grounds Shop -The shop is located on the North Access Road. Metal and other equipment are stored outside the shop. Runoff from this area is controlled by concrete drains and chutes prior to discharge into Stream A via Sedimentation Basin A. The pollutants of concern at this location are suspended solids and iron.4. Burn Pit Area -The Bum Pit Area is located east of the plant and adjacent to the switchyard.
Occasionally, scrap metal and empty containers are stored at this area. Runoff from this area is controlled by concrete drains and chutes prior to discharge into Stream B. The pollutant of concern at this location is iron.5. Spoils Area -Located East of the plant and adjacent to the Switchyard.
Portions of this area are used for temporary storage of metal, industrial equipment and portable buildings.
The pollutants of concern at this location are suspended solids and iron.6. Northeast Laydown Area -This area is located on the east side of the North Access Road. Metal, industrial equipment, concrete and wood materials are stored in this area. Runoff from this area is controlled by concrete drains and chutes prior to discharge into Stream A. The pollutants of concern at this location are suspended solids and iron.7. Northwest Laydown Area -This area is located on the west side of the North Access Road. Metal, concrete and wood materials are stored in this area. Runoff from this area is controlled by concrete drains and chutes prior to discharge into Stream A. The pollutant of concern at this location are suspended solids and iron.GGNSSWPP (REV 13) -9
- 8. Shooting Range -This is located on the west side of the Northwest Laydown area. Metal target stands and spent bullets are in the area. Runoff from this area into a holding pond and does not enter surface waters. The pollutants of concern at this location are iron, lead and suspended solids.g. Construction Areas 1. Plant areas are periodically subject to temporary construction activities over time. These areas typically comprise less than five acres. Runoff from these areas has the potential to contain suspended solids. However, impact from these activities are minimal due to GGNS' onsite sedimentation basins. [See Attachment IV].Attachment V lists current construction permits for construction activities with a potential to disturb more than 5 acres and includes requirements for managing these activities.
7.0 SPILL HISTORY 7.1 The Storm water Pollution Prevention Manager should update this section as needed, describing significant spills. For the purpose of this plan a significant spill is one which results in a notification to a regulatory authority.

Jim Kegerreis 601-437-2348 Contractor:
TBD GGNSSWPP (REV 13) -37 Enercon or their sub-contractors retain ultimate responsibility for determining the proper erosion control methods. Controls should, at a minimum, be in accordance with the standards set forth in "Planning and Design Manual for the Control of Erosion, Sediment and Storm Water" or other recognized manual of design as appropriate for Mississippi.
The planning and design manual can be obtained by contacting MDEQ at 601-961-5171 or may be found electronically at Mississippi State's educational website at http://abe.msstate.edu/csd/p-drn/.
In addition, Mississippi's "Storm Water Pollution Prevention Plan (SWPPP) Guidance Manual for Construction Activities" is available by calling MDEQ at 601-961-5171 or on the MDEQ website at www.deq.state.ms.us.
These erosion controls shall address the following minimum components:
Vegetative Practices shall be designed to preserve existing vegetation where possible and re-vegetate disturbed areas as soon as practical after grading or construction.
Such practices may include surface roughening, temporary seeding, permanent seeding, mulching, sod stabilization, vegetative buffer strips, and protection of trees.Structural Practices shall divert flows from exposed soils, store flows or otherwise limit runoff from exposed areas. Such practices may include construction entrance/exit controls, straw bale dikes, silt fences, earth dikes, brush barriers, drainage swales, check dams, subsurface drains, pipe slope drains, level spreaders, drain inlet protection, outlet protection, detention/retention basins, sediment traps, temporary sediment basins or equivalent sediment controls.Post Construction Control Measures shall be installed to control pollutants in storm water after construction is complete.
These controls include, but are not limited to, on-site filtration of run off, flow attenuation using open vegetated swales, exfiltration trenches and natural depressions, constructed wetlands and retention/detention structures.
Where needed, velocity dissipation devices shall be placed at detention or retention pond outfalls and along the outfall channel to provide non-erosive flow.PROJECT SCOPE: The construction of roads and maintenance of equipment storage areas including the limited removal of trees and the construction of unpaved access roads for the placement of geological/geotechnical test wells, bore holes and test pits. The total acreage that will be disturbed is conservatively estimated at 3.5 acres. The majority of these activities will take place west and south of the existing Protected Area (PA) perimeter.
GGNSSWPP (REV 13) -38 EROSION AND SEDIMENT CONTROLS: Primary potential impacts involve the construction of test pits, access roads in upslope areas, steep or unstable slopes, and the removal of trees in the immediate test areas, as required.
Note that these areas have been previously disturbed by either silvacultural or previous construction activities and efforts will be made to utilize the existing old access[logging]
roads, where possible.Other test areas include stabilized existing parking lots, paved roadways, and construction laydown areas minimizing potential surface water runoff impacts related to these sampling activities.
After testing is completed, access roads and similar disturbed areas will be re-vegetated to minimize future potential erosion impacts.The construction of access roads and the temporary storage of vehicles and testing equipment, such as drilling pipe, are anticipated to have a similar or less impact than those activities typically observed during small scale silvacultural and construction operations.
As mentioned, much of the testing occurs in areas already stabilized and maintained at grade on property primarily covered either by concrete, asphalt or gravel. Draining for these areas is provided by concrete ditches, spillways and catch basins that enter into an unnamed tributary that traverses GGNS property and enters into a sedimentation basin and eventually Hamilton Lake. This tributary is far enough removed from the test access areas to preclude any significant impacts on riparian trees or buffer zones. Storm drains located in the vicinity of these areas also enter directly into a sedimentation basin through National Pollutant Discharge Elimination System [NPDES] Outfall 007. Based upon previous similar testing activities, storm water impacts upon Outfall 007 will be negligible.
Storm drains in the vicinity of any test locations may be temporarily covered or otherwise secured to preclude any impact.The sedimentation basins were excavated during construction of the GGNS facility and were originally designed to slow the flow of storm waters and allow sediments from construction activities to settle out of solution before entering State waters. Although the sedimentation basins have not been maintained to original design specifications they are still functional and provide additional protection by ponding runoff in these controlled areas.The following controls will also be implemented, as required, to retain sediment on site: Disturb the smallest area possible by using existing access routes when possible.GGNSSWPP (REV 13) -39 Strategically place silt fencing, hay bales, or other barriers as needed to filter and slow storm water runoff.If required, temporarily cover storm drains to eliminate point sources of contamination.
Use hay bales, silt fencing, berms or other engineering controls to slow rainfall runoff velocities and prevent erosive flows.Minimize the amount of cut and fill.NON-STORM WATER DISCHARGES:
Non storm water discharges are regulated by the GGNS NPDES Permit. Contact Chemistry for approval before discharging any non-storm water.NATIONAL HISTORICAL PRESERVATION ACT: The Grand Gulf Nuclear Station was originally evaluated by the Mississippi Department of Archives and History during the construction of the facility.
This evaluation determined that operation of the station will not result in any impact on historic and archaeological sites in the area [Draft Environmental Statement, United States Regulatory Commission, May 1981, Page 5-7; Final Environmental Statement, United States Regulatory Commission, September 1981, Page 5-7).NOTE Work orders and procedures must include cultural resource specific written directions for excavation and backfill work which calls for an immediate stop-work order should archeological, historical, or other cultural resources be uncovered during excavation.
The construction supervisor is responsible for ensuring work stoppage and for notifying the Environmental Lead* of an inadvertent discovery.
In the event of an inadvertent discovery the Environmental Lead* will determine the inadvertent discovery's significance and if necessary, notify the State Historic Preservation Officer to consult with them regarding the discovery to determine if an additional archeological assessment is needed.* Environmental Leads: Rusty Shaw 601-437-7312 John Lassetter 601-437-2115 GGNSSWPP (REV 13) -40 HOUSEKEEPING PRACTICES:
GGNS requires the following housekeeping practices to minimize contamination of storm water: Equipment Maintenance and Repair: Major equipment repairs will be conducted at the Vehicle Maintenance Shop or offsite by the vendor.Minor field repairs may be performed provided that precautions are taken to assure fuel or oil does not contaminate the ground or storm water.These precautions include the use of drip pans, containment devices that are impervious to oil or fuel, absorbent pads and/or booms or other devices as required.In addition, vehicle and equipment maintenance activities should not be performed outdoors during periods of precipitation.
The equipment should be relocated, if possible, to an area that provides adequate protection from precipitation.
In emergency situations a shelter may be improvised to shield the equipment from precipitation provided that controls are implemented to prevent the contamination of surface storm water runoff.Concrete Chute Wash Off: A holding pond must be excavated in a laydown or other area sufficient in size and volume to contain the concrete residue and rinse waters from cement delivery trucks plus additional freeboard to assure that these waters are not mixed and/or discharged with storm water. No other washing will be authorized.
Waste Receptacles:
Waste receptacles such as dumpsters, roll-off boxes and similar devices should be placed at convenient locations.
Waste should be regularly collected and disposed of and not allowed to accumulate or overflow containers.
In addition, workers should police access, testing, and construction areas to assure that trash and debris does not contaminate or is not removed by storm water run off.Chemical Use and Storage: All chemicals must be approved by the Site Chemical Control Coordinator before they are brought on site. After approval each chemical container must retain the proper label(s), including the chemical control label, and be properly stored as directed by the Site Chemical Control Coordinator and in accordance with site safety and fire protection requirements.
GGNSSWPP (REV 13) -41 Chemicals may not be left unattended.
When chemicals are not in use they must be properly secured and stored.Protective clothing requirements are prescribed by GGNS Industrial Plant Safety.All personnel, including contractors are required to comply with the appropriate GGNS procedures and expectations at all times.Sanitary Facilities:
Sanitary facilities are located at various locations.
If these are not sufficient portable facilities must be provided that are in good structural condition and routinely serviced.Secondary Containment:
The storage of fuel and oil is governed by the GGNS Spill Prevention Control and Countermeasures Plan [SPCC]. Temporary fuel and oil storage as well as restrictions on draining water from containment devices must comply with the requirements of this plan.Temporary fuel and oil containers must have containment of sufficient volume to contain their contents plus 10% additional freeboard.
These must also be located in areas where they are protected from damage by vehicular traffic [Review the appropriate Environmental Regulatory Review for more detailed information].
In addition, temporary equipment not in use must also be provided with containment unless equipped with double walled tanks, skid pans or other devices capable of containing the entire contents of the tank.Water may not be discharged from containment devices if there is a visible sheen or other evidence of contamination.
Contact Chemistry for additional guidance prior to discharging potentially contaminated water from containment devices.Releases of Fuel, Oil or other Substances:
Any spill, regardless of the volume, must be immediately reported to the Control Room [X2374 or Radio Channel 11. The control room will dispatch trained HAZMAT responders if necessary.
If possible, spills should immediately be controlled so they do not mix with storm water or pose a threat to state waters.GGNSSWPP (REV 13) -42 All spills must be promptly cleaned and contaminated sediments removed.Chemistry will provide guidance for the remediation of spills and for the disposal of associated waste materials.

Commission means the Mississippi Commission on Environmental Quality.Clean Water Act "CWA" refers to the Federal Water Pollution Control Act, 33 U.S.C. section 1251 et seq.Discharge of Storm Water Associated with Small Construction Activity as used in this permit, refers to a discharge of pollutants in storm water runoff from areas where soil disturbing activities (e.g.. clearing, grading, or excavation), construction materials or equipment storage or maintenance (e.g., fill piles, borrow area, concrete truck washout, fueling), or other industrial storm water directly related to the construction process (e.g., concrete) are located.Executive Director means the Executive Director of the Department of Environmental Quality.Facility or Activity means any NPDES "point source" or any other facility or activity (including land or appurtenances thereto) that is subject to regulation under the NPDES program.GGNSSWPP (REV 13) -57 Large Construction Activity includes clearing, grading, and excavating resulting in a land disturbance that will disturb equal to or greater than five (5) acres of land or will disturb less than five (5) acres of total land area but is part of a larger common plan of development or sale that will ultimately disturb equal to or greater than five (5) acres. Large construction activity is covered by another general permit.Larger Common Plan of Development or Sale means a contiguous area where multiple separate and distinct construction activities are occurring under one plan. The plan in a common plan of development or sale is broadly defined as any announcement or piece of documentation (including a sign, public notice or hearing, sales pitch, advertisement, drawing, permit application, zoning request, computer design, etc.) or physical demarcation (including boundary signs, lot stakes, surveyor markings, etc.) indicating that construction activities may occur on a specific plot.Operator for the purpose of this permit and in the context of storm water associated with construction activity, means any party associated with a construction project that meets either of the following two criteria: I. The party has operational control over construction plans and specifications, including the ability to make modifications to those plans and specifications; or 2. The party has day-to-day operational control of those activities at a project which are necessary to ensure compliance with a storm water pollution prevention plan for the site or other permit conditions (e.g., they are authorized to direct workers at a site to carry out activities required by the SWPPP or comply with other permit conditions).
This definition is provided to inform permittees of MDEQ's interpretation of how the regulatory definitions of "owner or operator" and "facility or activity" are applied to discharges of storm water associated with construction activity.Owner or operator means the owner or operator of any "facility or activity" subject to regulation under the NPDES program.Permit Board means the Mississippi Environmental Quality Permit Board established pursuant to Miss. Code Ann. §49-17-28.Pollutant is defined at 40 CFR 122.2. A partial listing from this definition includes:

Geotechnical/geological investigation work This review is required by the following:
Grand Gulf COL Site Activity Review Form Items: N/A 50.59 Screening Items: N/A Air Operating Permit: N/A The GGNS Air Operating Permit [Mississippi Permit No: 0420-000231 does not regulate or prescribe limitations and conditions for geotechnical/geologic investigations provided that permanent fuel burning engines are not installed to facilitate the activities.
[This implements the Clean Air Act regulations referenced in EN-EV-)115; Section 2, Items 2 and 5(c).]National Pollution Discharge Elimination System Permit [NPDES]: N/A This activity will not create any new or additional discharges or the addition of any chemicals requiring either a modification to the GGNS NPDES Permit or notification to the state permitting authority.
The state permitting authority independently verified this -see GTC 2006/00007 and GTC 2006/00011.
[This implements the Clean Water Act regulations referenced in EN-EV-1 15; Section 2, Items 2 and 5(g).]Storm Water Permit/Plan:
N/A This activity does not initially involve any construction or land disturbance in excess of 1 acre and does not add a new source of industrial activity that would require a either a Construction Notice of Intent or an amendment to the GGNS Storm Water Plan.NOTE When it is determined that land disturbances such as bulldozing, tree clearing, equipment storage, or other construction activities inclusive to this project have the potential to exceed I acre; construction work must be stopped prior to exceeding the I acre limitation until a Construction Permit is transmitted to the state permitting authority.
If this work continues to expand and reaches the potential to exceed 5 acres, construction work must be stopped prior to exceeding the 5 acre limitation until the site environmental lead determines whether the state permitting authority will impose any additional requirements, such as a revised Construction Permit and the submittal of a Construction Notice of Intent.[This implements the Clean Water Act regulations referenced in EN-EV- 115; Section 2. Items 2 and 5(f). I GGNSSWPP (REV 13) -66 Spill Pollution Control and Countermeasures Plan [SPCCJ: The GGNS SPCC Plan requires any container
[including non-attended vehicle fuel tanks] with a capacity(2) equal to or greater than 55 gallons to be properly stored and maintained.
This means that containers for fuel, Hydraulic Fluid, Lubrication Oil, or any other oil must have containment sufficient to contain the volume of oil stored in the container plus 10% additional volume for freeboard.
GGNS expects that oil/fuel containers are properly stored and managed so there are no spills onto the ground or into surface waters. Use absorbent pads or similar materials to contain and absorb fuel or oil leaks from vehicles or other equipment.
Leaks and spills, regardless of volume, must be reported and documented in accordance with GGNS Administrative Procedure, 01-S-12-20, "Hazardous Materials Emergency Response Plan".Footnote (2): Capacity means the volume of the container, not the amount of material it contains.
For example, the GGNS SPCC Plan regulates a 55-gallon drum containing 30 gallons of oil. The GGNS SPCC Plan does not regulate a 35-gallon drum containing 30 gallons of oil.NOTE An oil or fuel spill in an amount sufficient to cause sheen upon surface waters [navigable waters] requires a notification to the U.S. Coast Guard National Response Center and subsequently state regulatory authorities.
This is also a Nuclear Regulatory Commission reportable event. All efforts must be made to properly manage and prevent any oil or oil containing material from entering a navigable waterway [For the purposes of this document these include the storm drain system, sedimentation basins, streams, Mississippi River, barge slip, barrow pits, and Gin and Hamilton lakes].[This implements the Clean Water Act regulations referenced in EN-EV- 115; Section 2, Items 2 and 5(e).)Endangered and threatened species: Although endangered species have been identified in the proximity of the Grand Gulf Nuclear Station none have been documented in the vicinity of this activity and the implementation of protective management plans is not required.
The sighting of an endangered species such as an eagle or a black bear must be immediately related to the site environmental lead. [This implements the Endangered Species Act regulations referenced in EN-EV-115; Section 2, Items 2 and item 5(h).J GGNSSWPP (REV 13) -67 National Historic Preservation Act: The Grand Gulf Nuclear Station was originally evaluated by the Mississippi Department of Archives and History during the construction of the facility.
This evaluation determined that operation of the station will not result in any impact on historic and archaeological sites in the area[Draft Environmental Statement, United States Regulatory Commission, May 1981, Page 5-7;Final Environmental Statement, United States Regulatory Commission, September 1981, Page 5-71.NOTE Work orders and procedures must include cultural resource specific written directions for excavation and backfill work which calls for an immediate stop-work order should archeological, historical, or other cultural resources be uncovered durng excavation.
The construction supervisor is responsible for ensuring work stoppage and for notifying the Environmental Lead* of an inadvertent discovery.
In the event of an inadvertent discovery the Environmental Lead* will determine the inadvertent discovery's significance and if necessary, notify the State Historic Preservation Officer to consult with them regarding the discovery to determine if an additional archeological assessment is needed.Environmental Leads: Rusty Shaw 601-437-7312 John Lassetter 601-437-2115

Groundwater Withdrawal:
MDEQ does not require a monitoring well to be permitted provided that the diameter of the well is less than 6 inches and the driller retains MDEQ certification.
Wells with a diameter equal to or greater than 6 inches will require a permit. All wells require the approval of the Environmental Compliance Coordinator before the work is initiated
[
Reference:
GTC 2006/000071.
Test Wells and Bore Holes: Please note there are specific regulatory requirements for abandoning or decommissioning well and bore holes that penetrate water bearing strata greater than 25 feet in depth. All wells and boreholes that penetrate water bearing stratum with a depth of 25 feet or greater below land surface require decommissioning by an MDEQ licensed water well contractor.
Those less than 25 feet in depth below the land surface do not require a licensed contractor but there are reporting requirements that apply regardless of who plugs the well or bore hole. We reauire that all drilling[reaardless of denthl is performed by an MDEQ licensed contractor to assure these reoulatorv requirements are met.[
Reference:
State Regulation LW-2, Chapter IV, Section G, Item 1].Industrial Safety: Any geologicallgeotechnical investigation work must comply with applicable Entergy fleet and GGNS site Industrial Safety procedures, requirements and expectations.
Test pits and similar construction activities may involve obtaining Excavation Permits, Confined Space Permits, or otherwise require approval from the site Industrial Safety Coordinator*
before work commences.
In addition specific personnel safety and Personal Protective Equipment requirements must also be verified before work commences.
