Mr. Peter Mainhardt Davis-Besse Plant Storeroom 5501 North State Route 2 Oak Harbor, Ohio 43449 Project: PRELhMINARY WETLAND EVALUATION, PROPOSED TEMPORARY CONTAINMENT AREA, Davis-Besse Plant, 5501 North State Route 2, Oak Harbor, Ottawa County, Ohio Job No.: 125959 Report No.: 125959-0702-420 Date of Report: July 19, 2002 Author: Julie K. Hewlett Report Consists of 3 Pages Ladies and Gentlemen: We are pleased to submit the following environmental service report documenting our preliminary wetland evaluation of the proposed temporary containment area. MVis. Julie K.Hewlett, Senior Geologist from Bowser-Morner, evaluated the study area on July 19, 2002. The weather was hot and cloudy at the time of the site visit. No significant precipitation had occurred for several weeks.The study area consisted of a narrow 2/10-mile long parcel. The attached First Energy drawing shows the general location of the study area. The study area was bounded on the south by a ditch and associated dike. Farther to the south was the open water edge of the Ottawa National Wildlife Refuge. The eastern terminus of the study area was the beach station pump house. The study area was bounded on the north by a service road and intake canal.The intake canal is scheduled for dredging. Temporary dikes are proposed to completely surround the study area perimeter. Dredge spoils pumped into the temporary containment area would be allowed to settle. Clear water would be pumped back into the intake canal and also be allowed to naturally decant. Dried spoils would be moved to a permanent storage location and the temporary dikes removed. It is our understanding that the roadway between the study area and intake canal would remain open for traffic.Study area observations indicate local topography is sloped from the roadway, in a southerly direction towards the ditch. The ditch and associated dike most strongly appear in the western portion of the study area, and fade away towards the east. Wetland hydrology (standing water)was noted only in the bottom of the ditch and in the open water edge of the Ottawa National Wildlife Refuge located nearby to the south of the study area.The vegetation community friom the roadway towards the ditch and dike appeared to consist of upland grasses and weeds. Shrubs and bushes consisted of willow, dogwood, and cottonwood. The ditch west end contained Phragmites, indicating wet conditions during part of the year.All Reports Remain The confidential Property Of Bowser-MomerAnd No Publication Or Distribution Of Reports May Be Made Without Our Express Witten Consent, Except As Authorized By Contract. Results Contained In This Report Are Reflective Only Of The Items Calibrated Or Tested. Vnless Otherwise Agreed, Samples Or Specimens Will Be Discarded Or Returned At Bowser-Morner's Discretion. Study area soils consist of cut and fill materials placed to raise the roadway and dikes above the W level of Lake Erie, when Davis-Besse was originally constructed. In our opinion, an upland community exists from the edge of the roadway across the study area towards the south to the dike arid associated ditch. The ditch appears to have been constructed to drain surface water form the roadway. Due to tile man-made character of the study area, lack of hydric soils and lack of near surface water, it does not appear to meet the requirements of a jurisdictional wetland.In our opinion, a temporary containment area could be constructed in the upland area between the roadway and the dike in the southwest portion of the study area. Where the ditch and dike appear to fade away in the southeastern portion of the study area, the upland community appears to extend all the way to the open water edge of the Ottawa National Wildlife Refuge.To facilitate settlement of suspended solids, temporary containment should offer sufficient volume and retention. Retention of suspended solids could be enhanced by configuration, deflector curtains, wing walls, and polymer injection. If additional engineering or scientific consultation is required, Bowser-Morner could provide these design services through a change order.We hope that this preliminary wetland evaluation of the proposed temporary containment area is sufficient for your project management needs. If you have any further questions, please contact our, office.¶Respectfully submitted,BOWSER-MORNER ASSOCIATES, INC.\ .' Julie K.

Reporting and Event Summary Question: a) Time, date and duration of release or discharge. b) Time and date of discovery of the release or discharge. c) Indicate the Ohio EPA spill number and the National Response Center case number.d) Provide an event summary.Response: a) The actual time, date and duration of the release is unknown. The release most likely occurred between approximately 0300 hours on January 16, 1994, (the last recorded vehicle refueling) and 1130 hours January 17, 1994 (the first recorded observation of pump malfunction). b) The actual time and date of discovery of the release of gasoline was approximately 1800 hours on January 18, 1994.c) The Ohio Environmental Protection Agency Spill Response Number is 01-62-0180. The National Response Center Number is 217385.d) On Monday, January 17, 1994, approximately 1300 gallons of gasoline were found missing from the above ground gasoline storage tank at Service Building 4. The gasoline is used to service site vehicles; pool cars, snow plows, etc. On the morning of January 17, the gasoline pump appeared to be malfunctioning. Gasoline was pumped from the tank and about eight gallons were pumped and the flow stopped. The storage tank level was checked and measured approximately 100 gallons. The measurement of the tank on Friday, January 14, indicated approximately 1470 gallons with 88 gallons being dispensed over the weekend. The last gasoline was pumped from the tank on January 16, 1994, at 0300 hours.Industrial Safety and Environmental were notified of the missing gasoline. The site was checked for indications of a gasoline spill.There was no evidence of gasoline in the concrete dike surrounding the tank, or of any amounts around the gasoline pump or inside the pump housing, or in any of the areas' storm water outfalls (i.e., marsh or ponds). No gasoline odors were present. Security was notified for potential theft investigation. On January 18, 1994, the tank and underground piping to the gasoline pump'were pressure tested with no evidence of any leaks. The gasoline tank was partially filled and the pump was tested by pumping gasoline through the pump. When the pump was stopped, gasoline was observed to be siphoning through the gasoline pump fire safety valve's atmospheric vent.This leak path was established when a diaphragm failed in the fire safety valve. This confirmed that the gasoline had been released to the environment, not stolen as was previously suspected. It is suspected that the fire safety valve's diaphragm failed due to the extremely cold RAOG 94-09 Enclosure Page 2 weather on January 16, 1994, and at 0300 hours, when the pump was last used, gasoline siphoned through the atmospheric vent until the pump's suction was uncovered (100-gallon tank level).At 1800 hours on January 18, 1994, notifications were made in the following sequence: the National Response Center, the State Emergency Response Center, and the Ottawa County Sheriff's Department as required for the local fire department and local emergency planning committee notifications. At approximately 2120 hours on January 18, 1994, the OEPA Division of Emergency and Remedial Response representative arrived onsite and inspected the spill area.Collection activities to date have recovered approximately 500 gallons of gasoline and determined how far the gasoline has spread. The gasoline is contained in the porous fill underneath the Service Building 4 parking lot and poses no environmental concerns as it has not entered the marsh area, and is confined within Toledo Edison's property. The leak has been isolated and repaired. See Attachment 2 for a sketch of the incident scene.2. Location Question: a) Location of the facility from which the release or discharge occurred.b) Location of the release or discharge. c) Longitude and latitude Response: a) Toledo Edison Company Davis-Besse Nuclear Power Station 5501 North State Route 2 Oak Harbor, Ohio 43449 b) Ottawa County Carroll Township Oak Harbor (nearest village)c) The longitude and latitude of the Davis-Besse-Nuclear Power Station is 410 36' N, 830 05' W. Attachment 1 contains a map showing the site location. The release was not transportation related. RAOG 94-09 Enclosure Page 3 3. Product Release Question: a) Chemical name (common name or technical name) and Chemical Abstracts Service (CAS) registry number of the substance involved in the discharge or release.Response: a) The material released was Gasoline, BP Super Unleaded (No CAS Number is available because the product is a mixture). The Material Safety Data Sheet (MSDS) is attached (Attachment 5). The material is not an extremely hazardous substance. The estimated release quantity was approximately 1300 gallons.4. Environmental Impact Question: a) Identify the environmental medium or media impacted and the extent of the impact.Response: a) The gasoline was released into the soil underneath the gasoline pump.The estimated area of contaminated subsurface soil is 2500 square feet.There appears to be a zone of gasoline-contaminated soil approximately six inches wide. This zone is approximately three feet below the ground just above the clay substrate. The spill is 400 feet from the nearest waterway, no navigable waterways have been or are anticipated to be affected.Collection activities to date have recovered approximately 500 gallons of the gasoline and determined how far the gasoline has spread. The gasoline is contained in the porous fill underneath the Service Building 4 parking lot and poses no environmental concerns as it did not enter the marsh area and was confined within Toledo Edison's property.Additionally, the soil beneath the porous fill material is composed of a clay substrate which is very dense and has prevented the gasoline from migrating deeper. Area storm water drains have been isolated to prevent the potential of the gasoline from being released off site.5. Monitoring and Detection Question: a) If the release or discharge was monitored, indicate the method of detection and concentrations. RAOG 94-09 Enclosure Page 4 Response: a) As described in Section 1.d., Event Summary, the gasoline leak is thought to have occurred during the weekend of January 15 and 16, 1994.The release path. to the ground is not a monitored pathway and was unnoticed by site personnel. For event detection specifics, refer to Section i.d., Event Summary.6. Mitigation and Containment Action Question: a) Amount recovered or neutralized. b) Describe any actions taken to reduce the impact of the release or discharge. c) Actions taken to respond and contain the release or discharge. Response: a) To date, approximately 500 gallons of gasoline have been recovered from the-gasoline recovery sumps that were dug to collect the gasoline, and storm water oil interceptors. These low collection points are being monitored and the material is being collected throughout the remediation process.b),Veather conditions (-IOF) predicted a low probability of migration at c) the time of the release. The storm water line oil interceptors were pumped out for initial recovery. Recovery sumps were dug to recover additional bulk gasoline which may be present and to determine how far the gasoline had spread. Attachment 2 contains a sketch of the incident scene. Approximately 500 gallons of gasoline has been recovered to date. Gasoline recovered from the recovery sumps has slowed. The remaining gasoline appears to be contained in the porous fill beneath the parking lot. Additionally, the storm water lines have been plugged to prevent any gasoline from leaving the site from this pathway. Further remediation activities to remove the residual gasoline contamination from the soil are currently being evaluated.

7. Preventive Actions Question: a) Provide plans to preventa recurrence of the release or discharge.

Response: a) The pump and above ground storage tank were taken out of service. The gasoline pump will be repaired and redesigned to ensure that any future pump failure would be captured in secondary containment. RAOG 94-09 Enclosure Page 5 8. Health Risks Question: a) Describe any known or anticipated acute or chronic health risks associated with the release or discharge. b) Advice regarding medical attention necessary for individuals exposed to the substance released or discharged. Response: a) No known or anticipated acute or chronic health risks are associated with the release as long as the plume is contained in the soil substrate and completely removed or remediated, and there is no migration into waterways or exposure to cleanup personnel. b) N/A 0 9.Question: a) Indicate any air, water or other permit numbers which may be pertinent to this incident.Response: a) The National Pollutant Discharge Elimination System (NPDES) permit number for the Davis-Besse Nuclear Power Station is 2IB00011*ED. The gasoline was contained to the Davis-Besse site. The gasoline did not enter into the "waters of the state" and posed no environmental concerns.Question: a) Provide a chronological summary of the incident. Include a chronology of communications with the state and local government agencies.Response;a) Chronological Review 10.Date Time Event January 17, 1994 ~1130 Measured tank level and noticed -1300 gallons of gasoline missing.0 RAOG 94-09 Enclosure Page 6 Date Time January 17, 1994 .1200 January 18, 1994 January 18, 1994 January 18, 1994 January 18, 1994 January 18, 1994 January 18, 1994 January 18, 1994 January 18, 1994-1000-1730-1830-1903-1918-1948 Event Environmental and Safety personnel responded to scene and commenced investigation.

Countermeasure contingencies for minimizing harmful discharges are required for both bulk storage containers and oil filled electrical equipment. 1.3 This business practice, in conjunction with RA-EP-02850, Hazardous Chemical and Oil Spills, the DBNPS Emergency (E) Plan, and requirements of the National Oil and Hazardous Substances Pollution Contingency (NPC) Plan, fulfills the requirements for the Spill Prevention, Control, and Countermeasure (SPCC) Plan.This plan is required for facilities storing greater than 1320 gallons in above ground storage containers or when greater than 42,000 gallons is stored in an underground storage container and the location provides potential for a harmful discharge of oil.2.0 APPLICABILITY/SCOPE

2.1 Adherence

to this Business Practice is Mandatory. Reference Section 5.0 for reporting, reference Section 6.2.5 for general oil clean-up actions, and reference Section 6.3 for specific system responses. 2.2 This business practice applies to personnel who may be responsible for implementation of the SPCC Plan. The scope of this business practice is to provide instructions and required information for oil spill prevention and mitigation from releases of all above ground containers greater than 55 gallons, which includes all bulk storage containers, all Underground Storage or Bunkered Tanks, and all oil containing electrical or operating equipment. 2.3 For Hazardous Waste Operations Emergency Response (HAZWOPER) implementation, activate RA-EP-02850. The Off-Normal Emergency Response Organization procedure provides detailed actions for immediate response to spills or discharges from oils and/or chemicals. DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 4 of 57 2.4 Oil discharges may require additional response and mitigation actions if mixed with other regulated constituents. NOTE 2.4.1 Hazardous substances 'inherent' to crude oil, gasoline, or oil products are not reportable under the Comprehensive Environmental Response Compensations Liability's Act (CERCLA) or Superfund Amendments Reauthorization Act (SARA).2.4.1 Consult the Resource Conservation and Recovery Act (RCRA) Contingency Plan/Spill Notification Requirements Business Practice (DBBP-CHEM-2003) for a listing of Reportable Quantities (RQs) for hazardous chemicals.

2.4.2 Consult

the CERCLA/SARA Hazardous Chemical Locations and Spill Event Guideline (ECG-04) for response plans and clean up of hazardous chemicals typically found at Davis-Besse. 2.4.3 For oil spills occurring from Polychlorinated Biphenyl (PCB) equipment, perform cleanup per required Toxic Substance Control Act (TSCA) standards found in the PCB Activities and Response Plan (ECG-07).3.0 DEFINITIONS 3.1 BULK STORAGE CONTAINER -Any container used to store oil (equal to or greater than 55 gallons), including prior to use, while being used, seasonal storage or temporary storage, stand-by storage, or prior to further distribution in commerce.Bunkered and completely buried tanks are considered bulk storage containers. Bulk storage containers require a regular schedule of integrity testing and when repairs are made as defined under the definition of "Repair" (such as tank repairs).3.1.1 Oil-filled electrical or operating equipment is not considered a "bulk container" per the SPCC regulations regarding secondary containment or integrity testing, however, countermeasures to prevent harmful discharges are required.3.2 DISCHARGE -Includes but is not limited to any spilling, leaking, pumping, pouring, emitting, emptying, or dumping, of oil no matter where it occurs. The discharge however may not be reportable if the oil never escapes secondary containment or is fully contained on site and is promptly cleaned up. A harmful discharge is reportable to the National Response Center (reference Section 5.0). Discharges greater than 25 gallons in a 24-hour period that originate from an Underground Storage Tank, and do not meet any other 'harmful discharge' criteria, are only reportable to the Bureau of Underground Storage Tanks (reference step 5.4.2). DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 5 of 57 3.3 EMERGENCY RESPONSE -A response effort by employees from outside the immediate release area or by other designated responders (i.e. local fire departments or contracted responder) to a spill event which results or is likely to result in an uncontrolled release of a hazardous chemical or oil. Responses to releases of oil (or hazardous chemicals) where no potential safety or health hazard exists or the potentials for harmful discharges are mitigated and no regulatory agency notifications are required, are not considered emergency responses.

3.4 ENVIRONMENT

-For the purpose of this business practice, means outside of the system or diversionary structures (drum, container, tank, pipeline, process vessel, etc.) intended/designed to contain a hazardous chemical or oil or prevent it's release such that it becomes a harmful discharge.

3.5 ENVIRONMENTALLY

EQUIVALENT METHOD -An alternate method for integrity testing that must effectively minimize the risk of container failure and allow detection of leaks before they become significant (reference (112.7(a)(2). Examples include: Elevated drums or shop built containers (shell capacity less than 30,000 gallons), when a frequent visual inspection is accompanied by additional actions to ensure containers do not come in contact with soil, such as, elevating the containers so all sides are visible during inspection, or placing on a barrier (synthetic liner) between the container and the ground.3.6 HARMFUL DISCHARGE -A 'harmful discharge' is a discharge that escapes secondary containment and can reasonably be expected to be discharged in harmful quantities into or upon navigational water of the United States, the adjoining shorelines or contiguous zones, or affect natural resources. Examples of harmful discharges include discharges that violate applicable water quality standards (causes a film, sheen or discoloration of water surface, or a sludge or emulsion deposited beneath water surface), or discharges which have migrated out of control of or off of company property.3.7 NAVIGABLE WATERWAYS -Indicates the following: 3.7.1 All navigable water of the United States (U.S.), and adjacent wetlands (for example, the marsh surrounding DBNPS).3.7.2 Tributaries of navigable waters of the U.S. (including adjacent wetlands). 3.7.3 All other waters of the U.S. such as intrastate lakes, rivers, streams, and wetlands which may be used for recreational or commercial (including commercial fishing)purposes. DAVIS-BESSE BUSINESS PRACTICE Number:___________________________________ DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 6 of 57 3.8 OIL -Includes petroleum; gasoline; fuel oil; oil refuse; and mixture of oil with wastes other than dredged oil.3.8.1 Oils contaminated with PCBs or hazardous chemicals, not inherent to the oil, shall also be considered hazardous chemicals. The RCRA Contingency Plan (DBBP-CHEM-2003), SARA/CERCLA Response Business Practice Guideline (ECG-04) or, the PCB Activities and Response Plan (ECG-07), as appropriate should also be consulted. 3.9 OIL BOOM -A floating device that confines oil spilled on the surface of a body of water.3.10 PERMANANTLY CLOSED -Containers are considered 'permanently closed' after all liquid or sludge is removed, connection line(s) and piping are disconnected and blanked off; all valves (except ventilation valves) have been closed and locked, and signs have been posted stating closure with a notation of the date of closure.3.11 REPAIR -Any work necessary to maintain or restore a container to a condition other than that necessary for ordinary day-to-day maintenance to maintain the functional integrity of the container and that does not weaken the container integrity. 3.12 SECONDARY CONTAINMENT -Countermeasures such as, cathodic protection of buried piping, double-walled pipes, earthen or natural structures or berming, oil interceptors, containment pallets, diversionary or drainage structure, employed to ensure containment of oil from breach of a container or piping, and is applied in accordance with good engineering practice and judgement. Secondary containment is required for all bulk storage containers. 3.13 SMALL SPILL OR DISCHARGE / INCIDENTAL RELEASE -Small spills or discharges (i.e. incidental releases of chemicals or oils) which can be absorbed, neutralized, or contained at the time of release by trained employees in the immediate release area or by maintenance personnel. An incidental release or discharge poses no safety or health hazard (i.e. fire, explosion, or chemical exposure), cannot be reasonably expected to be discharged in harmful quantities or pose a potential harmful discharge off-site, and do not require off-site notifications of the release. These spills/discharges/releases are not "spill events" and do not require "emergency responses. Note however, that in accordance with Attachment 5 of RA-EP-02850, even listed typical small or incidental releases must be reported to the Control Room. DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 7 of 57 4.0 RESPONSIBILITIES 4.1 The Supervisor -Nuclear Chemistry Services shall: 4.1.1 Provide overall administration of this business practice.4.1.2 Make required onsite and offsite notifications and prepare regulatory reports.4.1.3 Provide technical assistance during response and clean-up efforts to ensure timely mitigation of spill.4.1.4 Ensure that spill equipment or kits for use with potential oil discharges on site are stocked with emergency response equipment, or contractual arrangements are secured for emergency response.4.1.5 Designate site individual(s) as 'Emergency Coordinator'/'Oil Spill Response Coordinator' (primary and alternate).

4.1.6 Complete

a review and evaluation of the SPCC Plan at least once every five years and: 1. Amend within 6 months of changes in facility design, construction, operation, or maintenance, that materially affects the potential for oil discharge in harmful quantities of oil to into or upon navigable waters, adjoining shorelines shore-lines, contiguous zones, or that affect natural resources. Notifications may be made in accordance with Regulatory Applicability Determinations and Environmental Evaluations. Examples of activities potentially requiring amendments to the SPCC Plan include decommissioning of tanks or containers, replacement, reconstruction or movement of containers, reconstruction, replacement or installation of piping systems, and, changes in product or service or revision of standard operation or maintenance procedures affecting the plan.2. Amendments to the SPCC Plan must be implemented as soon as possible, but no later than 6 months following preparation of the plan amendment (no later than 12 months after the change or activity causing the amendment.)

3. The review shall include amendments to the plan within 6 months to include effective prevention and control technology if the technology has been field proven at the time of the review, and will significantly reduce the likelihood of a discharge in harmful quantities.

The reviews shall indicate if amendments are required, and if amended, certified by a licensed Professional Engineer (PE). DAVIS-BESSE BUSINESS PRACTICE Number:___________________________________ DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 8 of 57 4.2 Other actions for an oil spill response as required per RA-EP-02850 may occur concurrently with the SPCC Plan implementation. These actions may include: 4.2.1 The Shift Manager or designee may make required onsite notifications and determine if a spill event has occurred which requires implementation of HAZWOPER.4.2.2 Industrial Safety may prescribe personnel protective equipment and practices during an emergency response.4.2.3 The Superintendent -Nuclear Maintenance Services may direct isolation of site waterways during a spill event and provide clean up of spilled materials. 4.2.4 All DBNPS personnel shall immediately report oil spill events or observed oil discharges to the Shift Manager.4.3 All oil discharges shall be mitigated as soon as possible after discovery. 5.0 OIL DISCHARGE INITIATING CONDITIONS AND NOTIFICATIONS 5.1 If an 'incidental' release or discharge of oil does not meet conditions of reportable discharges listed under Step 5.2, and poses no threat of migration to the offsite environment or of becoming a "harmful discharge", then the SPCC Plan is not required to be implemented. Actions for immediate mitigation and cleanup of all oil discharges are still required. Reference RA-EP-02850, Attachment 5 for additional information for appropriate PPE or disposal information for incidental releases.5.1.1 Reportable NPDES violations which pose no threat of migration of oil or hazardous substance in harmful quantities or harmful discharges, do not require SPCC Plan implementation. Only the NPDES notification requirements as specified in the permit are imposed.5.2 The SPCC Plan notifications and appropriate mitigation responses shall be implemented as directed by the Supervisor -Nuclear Chemistry Services (or Emergency Coordinator designee) when one or more of the following conditions involving oil discharges has occurred: 5.2.1 Any oil release greater than 25 gallons within a 24-hour period originating from a registered Underground Storage Tank (UST) or associated piping.5.2.2 Any oil release greater than 25 gallons within a 24-hour period not solely contained within the facility.5.2.3 Any oil leakage which is suspected to be contaminated with a hazardous substance exceeding a Reportable Quantity, which is not solely contained within the facility.

== Description:==

The natural substrate surrounding the facility and indigenous to the area is blue clay, limiting natural permeability. The facility drainage is installed such that oil interceptors and catch basins discharge via storm sewers or diversionary systems to site controlled basins or ponds. The natural substrate under the operating facilities was excavated during construction and replaced with a low permeable highly compacted crushed stone. The parking lots are asphalt covered, and limited areas have concrete covers (such as the Dry-Fuel Storage Pad.) There are no significantly treed areas and only sparse areas of shrubs or grasses on the operating premises. The contingent marsh is densely forested and maintained by the U. S. Wildlife Service.A site topographic diagram is provided in Attachment 3.6.1.4 Name, address, and phone number of owner or operator: Name: FirstEnergy Nuclear Generation Corporation County: Summit Address: 76 South Main St. State: Ohio City: Akron Zip: 44308-1890 Telephone Number: 800-633-4766 6.1.5 Name or title of person in charge of facility: Name or title: Director-Plant Operations 6.1.6 Name of person responsible for oil spill prevention/mitigation at facility: Name or title: Shift Manager 6.1.7 Certification The Plan requires certification to attest the information contained in the plan is true, complete, and accurate, and prepared in accordance with good engineering practices.

Site response personnel are trained in the following and receive annual refresher training.1. Known failures or equipment malfunctions, and prevention procedures, practices, and opportunities to improve compliance, 2. Proper operation and maintenance of equipment to prevent discharge of oil 3. The proper procedure to follow in the event of an oil spill situation 4. Applicable Spill Prevention Control and Countermeasures (SPCC) Pollution Laws, Rules and Regulations, and site procedures for implementation. NOTE 6.2.3 Oil-filled electrical, operating and manufacturing devices or equipment are not exempt from integrity testing requirements of 40 CFR 112.8 (c)(6).6.2.3 Discussion of Oil Tank and Piping Testing/Inspection/Protection

1. 40 CFR 112.8 (c) states bulk storage containers must be regularly integrity tested. Integrity testing is a combination of visual inspection plus one other testing technique and is required for all above ground bulk storage containers.

Testing techniques include visual inspections plus hydrostatic testing, Ultrasonic, Radiographic, Acoustical, or other non-destructive shell thickness testing. Integrity testing includes leak testing for valves and piping. Tank supports and foundations should be included in these inspections. Also, the tank exterior shall frequently be observed for signs of deterioration, leaks that might cause a spill, or accumulation of oil in diked areas. Acceptable documented methods include Hybrid Testing, Industry Standards, and Environmental Equivalent.

a. The integrity testing applies to large field-constructed or field-erected welded metal above ground tanks (AST); name-plated as field-erected if less than 50 feet high and a 30 foot diameter (or without a name-plate if greater than 50,000 gallons), and small welded-metal shop fabricated AST not otherwise identified as field-erected with a volume less than 50,000 gallons.

DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page* SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 15 of 57 b. Industry Standards for containers built to specified design in accordance with recommended industry practices may be used for integrity testing by facility owners and operators and by the certifying PE as references of good engineering practice for assessing the fitness of service for containers, or evaluating the suitability of containers for continued service. Industry Standards for recommended practices for piping, valves and appurtenances, may also be applied. The PE may also implement "Hybrid" inspection programs based on professional judgment for unique circumstances, or when industry standards are not specific for a tank configuration. Examples of accepted Industry Standards include: API 653, STI SP-001, API 650, API 12C, API 12R1, API RP 575, API RP 12R1, API 570, API RP 574, API RP 1110, API RP 579, API 2610, ASME B31.2, ASME B31.4-2002, and DOT 49CFRParts 173.28, 178.803, or 180.605.c. The Environmental Equivalence provision applies to the inspection and appropriate integrity testing of bulk storage containers. The PE has the flexibility to offer environmental equivalent integrity testing options for all classes of tanks, including shop-built tanks above 30,000 gallon capacity and field-erected tanks, if the rationale is provided or appropriate industry standards are referenced.

d. In cases where a regularly scheduled inspection and testing program is not currently identified, no baseline information is available, and no environmental equivalence or Industry Standard for integrity is documented, the Industry Standard or strategy for regular testing must be identified and collection of baseline information testing must be scheduled within 10 years from tank installation, or within the first five-year review cycle of the SPCC Plan (within 5 years from effective implementation date of August 18, 2006 and completed by August 18, 2011) in order to establish a regular integrity testing schedule based on current container conditions.

Testing is performed under the site Work Management Program, or tracked for completion under the site Corrective Action Program/SAP Activity Tracking Items for integrity or baseline testing to be initiated (reference Attachment 11 notes for individual ASTs).2. All areas (zones) containing operational equipment, oil storage tanks and storage containers at DBNPS are periodically visually inspected by various groups, i.e. Operations, Maintenance, and/or Engineering. Periodic Maintenance and Testing activities for specific tanks, such as the Emergency Diesel Generator Fuel Oil Storage Tanks (40,000 gallon capacity each), are periodically drained and inspected internally. The requirements for the inspections and testing are managed and documented through the Work ,hk Management Process. DAVIS-BESSE BUSINESS PRACTICE Number:___________________________________ DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 16 of 57 3. The oil storage tank transfer lines at DBNPS are wrapped and cathodically protected. Inspections are performed on a standard preventative maintenance program, or as excavation activities allow. Any storage tank transfer line leakage from offloading of bulk oil would discharge via the storm system and oil interceptors to onsite secondary containment. Leakage from onsite transfer lines would be identified as indicated in Step 6.2.4 discussion.

4. Protection is additionally provided by the use of monitoring controls and secondary containment.

Tank levels are monitored visually, and by use of gauges and high level alarms. Level devices are regularly tested. Effluents discharged into navigable waters are site monitored by a NPDES permit.Portable storage tanks are required to have sufficient secondary containment.

5. The concept and nature of nuclear operations, training and frequent zone walkdowns ensures above ground valves and pipe-lines are subjected to regular visual examinations.

Station drainage and discharge is procedurally controlled.

6. Vehicular traffic within the protected area is minimal. IF vendor vehicles are allowed access, THEN the vehicle is accompanied by Security personnel.

7. Integrity testing, secondary containment, or new requirements are verified against 40 CFR 112.8 criteria pursuant to the 5-year required review.Deficiencies are tracked under the site corrective action program for implementation of acceptable corrective actions or countermeasures in accordance with Step 4.1.6. (example:

tracking through completion of applicable corrective actions for addition of brittle failure evaluations when field-constructed tanks of shell thickness greater than 1/2 inches are repaired.)

6.2.4 Discussion

of Oil Interceptors

1. All drains in the plant, where oil contamination is postulated, discharge to the Storm Sewer System via a Josam Oil Interceptor (exception is the East and West Condenser Pit Sumps, which are redirected to the Settling Basins). There are six (6) Oil Interceptors (01) strategically located to accommodate the drains in the station. Oil Interceptors 1, 2, 3, 4, 5, and 7 drain to the Training Center Pond. There are two (2) Oil Interceptors 6A and 6B, which are located in the northeast parking lot and which drain to the marsh. The parking lot by the Personnel Access Facility (PAF) does not have Oil Interceptors.

The Oil Interceptors are located in the following areas: DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 17 of 57 Oil Interceptor

1. 7: Service Building 6 Reference Drawing C-55 100-159 Gallon Capacity Influent Drain Source: Station Blackout Diesel Generator Fuel Storage Tank NOTE 6.2.4.2 Preventive Maintenance records are generated by maintenance services to document pumping activities.

Such records list, at a minimum, the date, area, and quantity of liquid pumped from the interceptor storage tanks.2. Each oil interceptor is equipped with an oil storage tank. These oil storage tanks collect and contain the oil accumulated from leaks, accidents or ruptures of oil systems, oil tanks and equipment containing oil. Levels in these tanks are periodically checked and pumped out in accordance with Work Management Process.3. If any of the oil interceptor storage tanks are overfilled in the event of oil spill, observe the south settling basin or Training Center pond for evidence of oil.Contain the oil by closing flapper gates in the Training Center Pond and/or turning off north settling basin pumps and using oil booms and absorbent material. Also, oil booms and absorbent material may be used at the spill source to contain and prevent more oil from entering, the oil interceptors. 6.2.5 Oil Discharge Cleanup -General Actions and Commitment of Manpower, Equipment and Materials 1. Symptoms a. Visible oil slick on surface of floor, ground, or water.b. Leaks from equipment containing oil such as pumps and lubricating lines.2. Specific Action a. Identify and mitigate fire, explosion or vapor hazards (implement RA-EP-02850 if HAZWOPER response is required).

b. Isolate waterways if applicable.

c. Visually inspect release site, monitor and mitigate further hazards.

DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page* SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 19of57 d. Use any equipment available, such as absorbents, oil booms, and sand bags, to minimize the leak, contain the released material, and prevent further release to the extent possible (Reference system specific responses listed in Section 6.3).e. Contact available vendors for supplies and equipment to control, contain, minimize, remove, and clean up the harmful discharge. If support in addition to the established contracted agreements are required, listings of supplemental Commercial firms may be located in the DBNPS Emergency Plan Telephone Directory.

f. Remedy hazards posed by contaminated soils or waste, and determine presence of release and free product removal techniques if applicable.

Soils and wastes shall be disposed of in accordance with the site waste handling procedure for Hazardous and Non-hazardous wastes, NG-DB-00504.g. For PCB oil spills, or hazardous substance oil spills, refer to Environmental Compliance Guideline ECG-07, or ECG -04, as appropriate, for clean-up response.h. For Oil spills within the RRA, follow ALARA precautions and use appropriate Radiation Protection procedures in addition to the applicable requirements of this procedure.

3. Discussion

a. The station is equipped with retention areas and oil interceptors to prevent any oil discharges and procedural controls (DP-OP-06272, Station Drainage and Discharge System) for Chemistry notification when drainage routing is altered. If an accident causes an oil spill on the roadways and parking lot, or the drainage system becomes contaminated with oil, every effort shall be made to determine the source and curtail any additional spillage.

Most of the storage containers have secondary containment by use of a containment dike, berm, or retaining structure, cathodic protection, or oil interceptors. The registered Underground Storage Tanks (UST) are not completely regulated under 40 CFR 280 Regulations due to exclusions for Nuclear Power Emergency Generator Status. The site-USTs are therefore regulated under both the SPCC Plan requirements and the UST regulations. Storage containers have been verified to be discharged to site controlled diversionary structures or ponds, which are monitored under the site NPDES permit, or contained within curbing or sumps inside the facility to prevent a harmful discharge. Countermeasures are required for the DBAB Emergency Diesel Generator Storage (and Day) tanks. The storage tank lines are not cathodic protected or wrapped, and the day tank does not have secondary containment. The tanks are designed to discharge to site DAVIS-BESSE BUSINESS PRACTICE Number:___________________________________ DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 20 of 57 Pond 19, located just west of the Cooling Tower. The pond does have a gate valve to prevent uncontrolled outflow and the out-fall is also a monitored release path under the site NPDES permit. For additional compensatory measures, outside contractor agreements are in place.Reference each specific discussion for a prediction of the direction, flow path, and total quantity of oil that may be discharged from each site container.

b. Transfer operations are performed under strict security and controls.Fugitive overfills will discharge to site diversionary structures.

Reference the specific discussions for each container. Total containment from the largest tanker discharged is required.c. Portable containers must have sufficient secondary containment for the entire contents and appropriate precipitation freeboard.

d. Precipitation will accumulate in the retention areas and is periodically pumped out by Maintenance Services.e. Various locations are equipped with oil spill pads, booms, or absorbants.

Water booms are used in conjunction with an oil weir at the discharge ponds from the oil interceptors. Contractual agreements ensure unnecessary delays are not encountered when outside support is required.Oil discharge response and cleanup are included in HAZWOPER personnel training. Reference the HAZWOPER procedure, RA-EP-02850 for additional site staged resources. 6.3 Oil Locations and Specific Oil Spill Situations

6.3.1 Diesel

Fuel Oil Storage Tank (DFOST) T45 Leak/Rupture (100,000 Gallons, Drawing 7749-C-34-18-5, Plant System 26-01)1. Symptoms Oil accumulation within the Diesel Fuel Oil Storage Tank retaining structure, or other evidence of tank leakage in the surrounding soils or down stream of catchbasin 31.2. Specific Action a. Utilize means available (drain covers, booms etc.) to keep oil away from catchbasin 31 (located just Northwest of the tank).b. Observe the Training Center pond for evidence of oil. Contain oil in the pond by closing flapper gates and using booms. Contact Environmental for additional support. DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 21 of 57 c. Isolate the tank or suspect lines from the system.3. Discussion The Diesel Oil Storage Tank is designed so that in the event of a leak or rupture, the retaining structure around the tank will contain the entire 100,000 gallon capacity of the tank, plus an additional 15,000 gallons of precipitation and fire water. Periodically, the retaining wall area is checked and any accumulated precipitation is drained to the Diesel Oil Pump House Sump, For the diesel oil storage tank, Computer Alarm L378 receives data from tank contents level transmitter LT 1441 (Foxboro Electronic Transmitter, DP Cell).LT 1441 is located in the southeast quadrant of the retaining moat, about 1.5 feet above the moat floor, near the moat floor access ladder. A local level indicator gauge is also located in the southeast quadrant of the moat area, about 6 feet above the moat floor under the tank access catwalk. This level gauge (LIS-1 102, Varec Figure #2500 Series, Model B) is used to determine amount stored and to monitor amount in tank during filling operations. Any oil leakage into the backfill/catchbasin 31 is routed via the storm sewer to the Training Center Pond. The pond has a weir at the influx and is able to be isolated.6.3.2 Diesel Fire Pump Day Tank T47 Leak/Rupture (350 Gallons, Drawing M-140-00028, Plant System 26-03, Intake Structure 575')1. Symptoms Oil accumulation within the Diesel Day Tank retaining curb.2. Specific Action a. IF the Diesel Oil (DO) Transfer Pumps, P8-1 and PB-2, are transferring oil to the Diesel Fire Pump Day Tank b. THEN stop the DO Transfer Pumps P8-1 and P8-2 1) P8-1 is powered from MCC E12B (BE 1257), control switch HIS105.2) P8-2 is powered from MCC F12B (BF 1257), control switch HIS1106.3) The control switches may be placed in lockout positions.

3. Discussion The Diesel Fire Pump is the backup fire safety system to the electric fire pump.The Diesel Fire Pump Day Tank may be filled with the use of the Diesel Oil Transfer Pumps P8-1 and P8-2. The Diesel Fire Pump Day Tank (capacity 350 DAVIS-BESSE BUSINESS PRACTICE Number:___________________________________{

DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 22 of 57 gallons) is designed so in the event of a leak or rupture the retaining curb around the tank will contain any accumulated oil.6.3.3 Emergency Diesel Generator (EDG) Day Tank(s); T46-1 and T46-2 Leak/Rupture (12,000 Gallons Each, Drawing 7749-M129-1-3, Plant System 26-02, Rooms 320A/321A)

1. Symptoms of Leakage Oil accumulation within a Diesel Generator Day Tank Area (Room 321A-Day Tank 1 / Room 320A-Day Tank 2)2. Specific Action a. In the event of a rupture in the Day Tank(s) 1-1 or 1-2, respectively:

1) Stop EDG Fuel Oil Storage Tank 1-1 Transfer Pump P195-1 with local breaker BE1298 (MCC E12F)2) Stop EDG Fuel Oil Storage Tank 1-2 Transfer Pump P195-2 with local breaker BF 1230 (MCC F12A)b. Use portable pumping equipment to pump the fuel oil from Oil Interceptor

1. 5 directly into appropriate containers.

3. Discussion

a. Due to special seismic construction in the area where the Diesel Generator Day Tanks are located, a rupture is very unlikely.

Any fuel oil accumulated from leaks in the Day Tanks (total capacity 12,000 gallons, 6000 gallons per tank), Diesel Generators, or associated piping, are removed by the floor drains to the station process drains/storm sewer system via Oil Interceptor (01) #5, and containment at Training Center Pond in the event of OE #5 overflow (250 gallon capacity). Also refer to Step 6.2.4.3 for further actions/discussions in the event the oil interceptor storage tank overfills.

b. In the event of a rupture, oil may be pumped to the Transformer Collection Tank and removed to appropriate containers.

Symptoms Oil accumulation on the ground in the vicinity of the Emergency Diesel Generator Fuel Oil Storage Tanks.S1 0 0 DAVIS-BESSE BUSINESS PRACTICE Number:___________________________________ DBB P-OH EM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 23 of 57 2. Specific Action a. Utilize all means available (storm sewer drain covers, booms, etc.) to keep oil away from Catch Basin 17 (located just south of the tanks), and Collection Box 32 (located off the Northwest Corner of the tanks).b. Observe the pond by the Davis-Besse Training Center for evidence of oil.Contain oil in the pond by closing the flapper gates, and using oil booms.The 40K DFOST spill equipment: sewer covers, pads or booms, are located in Service Building 2. Contact Environmental for additional equipment.

c. Isolate the tank from the system.3. Discussion Each tank has a 40,000 gallon capacity.

if a rupture or leak occurred below the level of liquid, the fuel oil would leak into the ground, requiring extensive cleanup. Local level indicators (analog meters) are located adjacent to the filling point for each tank. Input for each indicator is received from a capacitance probe that is located within the tank (Indicator LI 4891 receives input from probe in Tank T1 53-1; Indicator LI 4892 receives input from probe in Tank T1 53-2). The indicator registers from 30,000 gallons (0%) to 40,000 gallons (100%) on an inverse logarithmic scale, with a high level local alarm light setpoint of 39,850 gallons and a low level local alarm light setpoint of 38,000 gallons. Periodic monitoring of tank inventories and close monitoring of fuel oil levels during filling procedures should prevent overfills from occurring. The tanks are registered as Underground Storage Tanks.6.3.5 Miscellaneous Diesel Generator Day Tank T168 Leak/Rupture (750 Gallons, Drawing 7749-M-1 25-114, Plant System 99-06)1. Symptoms Oil accumulation in Room 331, Miscellaneous Diesel Generator Day Tank Room.2. Specific Action a. Operations is notified that a High/Low Oil Level Alarm has been received from the Miscellaneous Diesel Day Tank.b. Verify if there is (or is not) a tank leak/rupture. DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 24 of 57 c. IF a tank leak/rupture exists, close Isolation Valve DO 112, Miscellaneous Diesel Day Tank Isolation Valve, in the Miscellaneous Diesel Day Tank Room, d. THEN stop the Diesel Oil Transfer Pumps, P8-1 and P8-2, if they are running.1) P8-1 is powered from MCC E12B (BE 1257), control switch HIS 1105.2) P8-2 is powered from MCC F12B (BF 1257), control switch HIS 1107.3) The control switches may be placed in lockout positions.

3. Discussion

a. The Miscellaneous Diesel Day Tank Room is a retaining structure with no floor drains that will easily contain the contents of the 740-gallon Capacity Tank.b. Valve DO 112 should be opened only when filling the Miscellaneous Diesel Day Tank.c. Normally the tank is gravity-filled from the Diesel Fuel Storage Tank.6.3.6 Turbine-Generator (T-G) Lube Oil (LO) Storage Tank T32 Leak/Rupture (2 Tanks;- 14, 0000 Gallons Each, Plant System 89-01, Room 432,)1. Symptoms Oil accumulation within the T-G Lube Oil Tank Room, or actuation of Annunciator, Computer Points 9-6-1 (ref OS-024A, SH 2)2. Specific Action If a temporary pump is in the sump, ensure the pump is also shut off.3. Discussion The tank is equipped with Annunciator (computer point 9-6-D) and Level Alarms (LSH 1165 and LSH 1250) tested per Maintenance Program (PM 1544).Visual inspections by periodic system walk downs are also performed.

Any oil accumulation from a leak or rupture in the T-G Lube Oil Tank Room or the Lube Oil Storage Tank Room will drain into the Lube Oil Storage Tank Room Sump. The Sump pumps for that sump have been permanently disabled, so the accumulated oil would be contained in the Lube Oil Storage Tank Room, thus preventing any oil from reaching the storm sewer system. In the event the oil interceptor storage tank is overfilled, refer to Step 6.2.4.3 for further actions.S 0 DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 25 of 57 6.3.7 Main Feed Pump Turbine (MFPT) Lubricating Oil (LO) Tanks (2) or MFPT Used LO Tank Leak/Rupture (MFPT-LO-1200 Gallons Each, MFPT Used LO is 2800 Gallons, Plant Systems 36-04, 565 Elevation)

1. Symptoms Oil accumulation in MFPT LO Tank pit or West Condenser Pit Sump (drains to sump via floor drains).2. Specific Action a. Stop Condenser Pit (west) Sump Pumps by, opening the breakers at MCC E32B (BE 3289) for Sump Pump P 33-A and F32B (BF 3289) for Sump Pump P 33-B.b. If there is a temporary sump pump installed in the West Condenser Pit used to pump to the East Condenser Pit, ensure the temporary pump is also shut off; it will be powered via a lead cord from a nearby 1 10V receptacle.

3. Discussion

a. Some oil leaks from the MFPT LO Tanks #1 and/or #2 will accumulate in the MFPT LO Tank Pit. The Pit has drain plugs in place to prevent oil and liquid draining to the West Condenser Pit Sump through the floor drains.The West Condenser Pit Sump Level is automatically controlled by Sump Pumps P 33-A and P 33-B, which may either discharge to the Settling Basins if the redirect is in place or discharge to the storm sewer via Oil Interceptor

1. 2, which has an oil storage tank capacity of 250 gallons.Normal discharge path is to the Settling Basin. Sump pump discharge flow to 01 may be approved by Chemistry (per DB-OP-06272, drainage line-up changes require Chemistry notification).

In the event the oil interceptor storage tank is overfilled, refer to Step 6.2.4.3 for further actions.b. In the event of a large rupture in the MFPT LO Tanks (1200 gallons each), or the MFPT Used LO Tank (2800 gallons), stopping Condenser Pit (West)Sump Pump 1-IA at MCC E32B (BE 3289) and for Sump Pump 1-1B, MCC F32B (BF 3289) will cause the following events to occur: 1) Oil level in the sump will reach a High level.2) High oil level will start the Condenser Pit Flood Pump P 174-1, which discharges to the settling basin.

Discussion In the event of a rupture in either 'Spare' Transformer, an earthen berm retaining structure will collect the leaking oil. A rain run-off drain in the berm is able to be isolated with a temporary drain cover to prevent storm run-off of oil in the event of oil leakage, or during maintenance activities posing concerns for oil leakage.6.3.14 Electro-Hydraulic Control (EHC) System Leak or Tank T79 Leak/Failure (800 Gallon System, Plant System 93-01)1. Symptoms For a leak, perform a visual inspection.

2. Specific Actions a. Operations performs those actions required by alarm procedures.

b. Identify and cover floor drains in the area of the spill.c. Dike and protect grating area near EHC Sump on 585 Level.d. Soak up spilled material with Absorbal, clay, sawdust, or fuller's earth.e. Flush spill area with detergent and water.3. Discussion The EHC system provides hydraulic fluid at sufficient pressure to operate the turbine valves; turbine stop and control valves, and combined intermediate valves. Because of the high temperature involved, normal hydraulic fluid would pose a fire hazard. To avoid this, the EHC system utilizes "Fyrquel EHC" as an operating medium. The EHC skid capacity is 800 gallons. Fyrquel -EHC has an open cup flash point of 4550 F and is a Tri-Aryl Phosphate Ester. The material is not corrosive to glass or metals, but will soften and deteriorate plastics and elastomers.

The product is not considered a hazardous waste and is not regulated by the EPA, however, hazardous by-products may be released when exposed to extremely high temperatures (i.e. steam).

3. Discussion The DBAB EDG Fuel Oil Storage Tank (Capacity 8,000 gallons) is an underground storage tank constructed of fiberglass reinforced plastic with no internal tank protection and piping is of bare steel (no cathodic protection).

This tank is registered as an Underground Storage Tank. Leakage is routed to site Training Center Pond that is able to be isolated. Temporary Transportation Load Pad is available for use during loading/offloading fuel.6.3.21 Fuel Tanks Located At Service Building 4 (Diesel is 1,000 Gallons and Gasoline is 2,000 Gallons)1. Symptoms Diesel fuel and/or gasoline has accumulated within the concrete dike surrounding the fuel tanks.2. Discussion The diesel fuel storage tank (capacity 1,000 gallons) and gasoline storage tank (capacity 2,000 gallons) are contained in a concrete retaining structure. This structure is designed to contain the total volume of both tanks plus an additional 15% capacity for precipitation and fire water. Periodically, the diked area/structure is checked and any accumulated liquid is removed to the appropriate waste drum or rain/storm water is inspected to ensure compliance of no oil sheen or other water quality nonconformance prior to supervised drainage. In the event the tanks are taken out of service, two 500 gallon temporary storage tanks with secondary containment may be staged. DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 33 of 57 NOTE 6.3.22 a. The Chemical Waste Storage Area (CWSA)is located outside of the Protected Area northeast of the Switch Yard.b. Chemical Waste Accumulation Areas (CWAAS) may be located at the following areas: 1) Self-contained storage building adjacent to the north Train Bay Door of the Turbine Building, within the Protected Area 2) Self contained storage/containment pad outside the Mechanical Shop (oil/refuse only).3) Self contained storage outside Service Building (SB) 6, SB 4, and the 100K and 40K DFOST storage tanks.6.3.22 Waste Diesel Fuel/oil in Containers in Chemical waste Storage Area (CWSA), Chemical Waste Accumulation Areas (CWAA), or Warehouse Storage 1. Symptoms a. Oil accumulating within the curbed, concrete pad, self-contained building, or floors of the CWSA, the CWAAS, or warehouse.

b. Oil overflowing the curb or containment part of the building and accumulating on the gravel, stone, asphalt, grass, or other ground surfaces surrounding the CWSA or CWAAS.2. Specific Action a. Use any equipment available, such as absorbents, oil booms, and sand bags, to minimize the leak and contain the spill.b. Contact the Supervisor

-Nuclear Chemistry Services if any leaking or spilled diesel fuel/oil drums are found at the CWSA or CWAAS. DAVIS-BESSE BUSINESS PRACTICE Number: DBBP-CHEM-2005 Title: Revision: Page SPILL PREVENTION CONTROL AND COUNTERMEASURE (SPCC) PLAN 01 34 of 57 3. Discussion

a. The station is equipped with retention areas and oil interceptors to contain any oil spills. The oil interceptors may be utilized in the event of a large oil spill or leak from 55-gallon drums at the CWAAS.b. Any oil leak or spill from 55-gallon drums at the CWSA is contained in the curbed concrete pad. Oil should be removed, thus preventing eventual accumulation to a volume that could enter the nearby drainage ditch which drains to the Training Center Pond.c. Any oil leak or spill in the warehouse storage from 55 gallon drums would be contained within the building.

Oil should be removed preventing accumulation or storage hazard using absorbents and/or booms.6.3.23 Equipment Containing Dielectric Fluid 1. Substations containing transformers are located through the plant. All transformers on site have been either retrofilled or replaced with non-PCB units. However, some large pumps, such as the Condensate Water Pumps, have been found to contain PCB capacitors. The exception are the four Circulating Water Pumps; which have been replaced with non-PCB capacitors, and the four Reactor Coolant Pumps; which are Non-PCB -dry pumps.Currently, it is unknown if the other pumps of this size or larger contain PCB capacitors. Therefore, it is prudent to assume the capacitors are PCB in a spill situation until determined otherwise. This equipment includes the following:

a. Condensate Pumps 1-2 and 1-3 motor capacitors (pump 1-1 has been replaced with non-PCB capacitors)

b. Service Water Pump motor capacitors

c. Component Cooling Pump motor capacitors

2. Other equipment which may contain PCB oil includes Cyberex inverter capacitors, and overhead lighting capacitors.

Is it therefore prudent to also assume the oil from these and/or unknown sources are PCB in a spill situation until determined otherwise. Reference Environmental Compliance Guideline-ECG-07 for currently known PCB containing equipment and mitigation instructions.

This OE resulted in CR 03-2360 being generated to evaluate the OE for Davis-Besse. OE 15788 described the condition at Salem where the leakage detected by their Spent Fuel Pool (SFP)leak detection system gradually diminished to zero over time. Salem uses a system of tell-tale drains similar to that used at Davis-Besse. After workers got contaminated on their shoes, investigation found a"calcium like substance" adhering to the wall of the room adjoining the Spent Fuel Pool. It was discovered that the leak detection system had plugged with boron over time and caused the water to accumulate until it migrated to other locations. Procedure DB-SP-04400, Spent Fuel Pool, Fuel Transfer Pit, and Cask Pit Leak Detection System Test, is performed monthly to quantify a leak rate from the 21 leak chases for those three pools/pit. Review of the results of the leak detection testing is performed by the SFP system engineer. Leakage outside the leak chase drains has been seen in several places over the years (ref. CR 02-01364, 01-02309 and 01-00253). The most extensive visible evidence of leakage was on the wall and ceiling of #1 ECCS Pump Room, Rm. 105 during the period 2000-2001 (note: this leakage has since been stopped and the area cleaned). The ceiling in this room is at 563' elev. which is the approximate level of the bottom of the pool (563.5'). Based on the evaluations associated with this past leak and the work done as part of the Containment Health there are no concerns regarding the strength or integrity of the concrete structure associated with these leaks.During the reracking of the SFP during Cycle 13, underwater divers used a vacuum box of the weld seams in the SFP to determine if there was any detectable leaks. None could be located.At the time that there was the very visible leakage in the #1 ECCS Pump Room, little leakage was being Page 1 of 3 Site: G201 INVESTIGATION

SUMMARY

CR Number: NOP-LP-2001-06 04-01719 seen in the leak chases. WO 00-5281 -00 was used to open/ verify open the 21 leak chase valves and piping in Feb 2001. Six of the chases were found to be totally blocked. A significant amount of trapped fluid was found in several of the blocked leak chases. As part of this the normal position of the leak chase valves was changed from OPEN to CLOSED. This should reduce the likelihood of the boric acid to solidify and block the valves and piping. To be certain this has not occurred again, an order to open/verify open the valves and piping has been initiated as CA 1 for CR 03-02360.While the zones with significant fluid were not the zones that cover the walls adjacent to the exterior (i.e.southern ends of the SFP or Cask Pit (CP)), several of these zones were shown to be blocked and these zones do show leakage during the monthly test. Based on this it is prudent to verify the soil does not show contamination which would be indicative of past and/or present leakage. This is being done by CA 2 to CR 03-02360.The 5' thick south wall of the SFP and CP form the outside wall of the Auxiliary Building. Much of the flooded portion of the SFP and CP are below grade and not visible. There Is a waterproof membrane on this outside wall (ref. DWG C-230 Section C) to keep outside groundwater from leaching into the Auxiliary Building. This membrane would also likely act to keep any potential fuel pool leakage from escaping into the soil.Thus while It Is unlikely that there would be leakage into the soil, without a some type of excavation or soil borings to gain access to the soil in this area it can not be conclusively determined that there has or has not been leakage.Should leakage be detected a further CR will be generated in accordance with, and required by, procedure NG-DB-00244, Radioactive Material Control Program, section 6.2.10. This section deals with contamination in and around the facility to ensure that the requirements of 1 OCFR50.75(g) are met.Contacts: None Source Information: IN 2004-05 CR 03-02360 DB-SP-04400, Spent Fuel Pool, Fuel Transfer Pit, and Cask Pit Leak Detection System Test Various site drawings including: C-230 and C-211 Most Probable Cause: This is an information notice and thus there is no most probable cause.Preventative/Corrective Action: No specific corrective actions are required by this CR as the corrective actions specified in CR 03-02360 adequately address the Issue.A copy of those are provided below.1.

It is expected that recipients will review the information for applicability to their facilities and consider actions, as appropriate, to avoid similar problems. However, suggestions contained in this information notice are not NRC requirements; therefore, no specific action or written response is required.Description of Circumstances: On September 18, 2002, the licensee for the Salem Nuclear Generating Station identified evidence of radioactive water leakage through an interior wall located at the 24-meter (78-foot)elevation of the Unit 1 auxiliary building mechanical penetration room, a radiologically controlled area. The leak location, about 3 meters (10 feet) up a wall surface, was identified while the licensee was following up low-level shoe contamination of personnel who had traversed the room. The licensee established a comprehensive task action plan to identify and stop the source of the leakage and evaluate possibly undetected leakage outside building structures. The licensee did identify other locations where radioactive water was leaking through interior walls or penetrations into both the Unit 1 auxiliary building and the Unit I fuel handling building (FHB).On February 6, 2003, the licensee identified the radionuclide tritium (H-3) in groundwater in two test locations near the Unit 1 FHB. The test locations were within the licensee-controlled restricted area. The licensee identified other locations of groundwater contamination in the general vicinity of the Unit I FHB and within the restricted area. No other reactor-produced radionuclides were detected in the groundwater sampling test locations. ML040580454 04-01719 IN 2004-05 Page 2 of 4 The licensee obtained technical support and concluded (based on leak testing of suspect systems, chemical analysis of water samples, system and building configuration reviews, and a geohydrological evaluation) that the likely source of the tritium was the Unit 1 spent fuel pool (SFP). The licensee believes that the leakage was the result of the obstruction of the leakage detection and collection system of the SFP stainless steel liner.Discussion: The Salem Unit 1 FHB is a seismically qualified structure that contains the Unit 1 SFP. Unit 1 SFP support systems in the Unit 1 auxiliary building pass through adjacent building walls to the Unit I FHB. The walls are separated by a Styrofoam -filled 15-cm (6-inch) seismic gap and the support systems traverse the seismic gap.The Unit 1 SFP is a concrete structure with a stainless steel liner. The SFP includes an integral liner leakage detection and collection system, consisting of an extensive network of collection lines running both horizontally and vertically within the narrow gap between the SFP liner and the concrete SFP structure. The collected liner leakage is discharged to a collection trough through 17 drain lines (tell-tale drains). The tell-tale drains provide a means to detect, monitor, and quantify potential leakage from the SFP liner. The collected leakage is subsequently directed to the liquid radioactive waste system for processing. The licensee's reviews discovered that over the years since initial facility startup, materials such as boric acid residue and minerals accumulated within the leak collection and detection system and restricted the normal drainage of liquid. The reviews also found that a modification to the tell-tale drains in 1998 resulted in the inadvertent introduction of sealant into the tell-tale drains, further restricting the free drainage of leakage from the liner. As a result, through-liner leakage accumulated between the SFP liner and the concrete structure of the SFP. The accumulated water, containing tritium, subsequently migrated to other locations through penetrations, concrete construction joints, and cracks. The seismic gap was confirmed to contain water with radionuclides characteristic of Unit 1 SFP water. The water is believed by the licensee to have made its way to the groundwater in the restricted area via the seismic gap.The licensee cleaned the tell-tale drains, improving the drainage of the accumulated water between the liner and spent fuel pool concrete structure and stopping the through-wall and penetration leakage. After the cleaning effort, the leak rate from the tell-tale drains increased from about 19 liters per day (5 gallons per day) to about 380 liters per day (100 gpd). The leakage was properly collected. The NRC conducted a special inspection of this issue (NRC Inspection Report 50-272/2003-006; 50-311/2003-006, ADAMS Accession No. ML032890212). The NRC's and the licensee's reviews identified the following information about this situation. 0 IN 2004-05 Page 3 of 4 1. The licensee took actions to identify specific leak locations, repair and mitigate the leak, and assess potential health and safety impacts. A comprehensive groundwater sampling and analysis program was implemented. Although the licensee believes, with a high degree of confidence, that the leak originated from the SFP, the licensee is continuing evaluations to confirm this conclusion. The leakage itself was not accompanied by large fluctuations in SFP water levels and was likely masked by approximately equal volumes of evaporation from the SFP.2. The licensee stopped the identified through-wall leakage by cleaning the tell-tales and resumed controlled collection of SFP liner leakage via the installed leakage detection and collection system. Extent-of-condition reviews revealed no apparent accumulation of water between the SFP liner and concrete structure at Salem Unit 2.3. The licensee's evaluations did not identify any immediate health and safety consequences to onsite workers or members of the public. No radionuclides associated with the leakage were detected outside the onsite areas administered as access-controlled areas for purposes of radiation protection. The licensee did not detect any tritium associated with this leak in areas accessible to the public (i.e., the unrestricted area). The licensee subsequently developed and implemented an onsite groundwater remedial investigation work plan in conjunction with State of New Jersey representatives.

4. The Unit 1 SFP had exhibited detectable leakage from the tell-tales since initial plant operations.

To monitor leakage from the tell-tales, the licensee established a surveillance program. Over the years, the leakage from the tell-tales diminished but the licensee was not able to tell from leakage changes if they needed further evaluation. There was also a missed opportunity to evaluate earlier through-wall contaminated leakage for possible accumulation of water between the Unit I FSP liner and concrete structure.

5. There was no periodic maintenance of the SFP leakage detection and collection system to ensure that drainage channels remained free and clear so that the system could perform its design function of preventing water from accumulating behind the FHB walls.The licensee initiated actions to develop a cleaning and maintenance process.6. The licensee conducted evaluations of potential short-term adverse impacts to the SFP structure.

The preliminary evaluations did not identify any adverse effects that would impact the design bases of the SFP or FHB structure. Nonetheless, the licensee initiated laboratory testing of the effects of boric acid on concrete. The results of these tests are being evaluated by the licensee for potential long-term effects.The licensee developed numerous corrective action documents to track the review, evaluation, and correction of identified deficiencies.

SUMMARY

OF POLLUTANT SOURCES-Page 1 of 2 The following significant materials have been stored on-site within the last three years within the described storm water discharge areas: 1. Outfall 1 (NPDES Outfall 002)a. Chemical Waste Storage Areas (CWSA)The CWSA is an enclosed structure with a curbed concrete pad to contain any potential leaks. The pad is divided into three separate sections as follows: 1)hazardous waste, 2) waste oil and non-hazardous wastes, and 3) chemical identification. In the event of a large quantity leak, the flapper gates for the drainage ditch behind the facility can be closed to isolate the spill. Also, the CWSA is inspected on a weekly basis.b. Chemical Waste Accumulation Areas (CWAA)There are two CWAAs in this storm water discharge area. These two CWAAs are only for diesel fuel. They each consist of two 55-gallon drums contained in the water-tight plastic storage containers.

c. Sodium Hypochlorite (NaOCI) Tank The NaOCI tank, which is located at the site water treatment plant, has a maximum capacity of 7,500 gallons and contains a 15% solution.

This tank has a dike structure designed to contain 115% of the tank capacity.d. Sodium Bromide (NaBr) Tank The NaBr tank, located at the Water Treatment Plant, has a 4,500 gallon capacity and contains a 43% solution. This tank has a dike structure designed to contain 110% of the tank capacity. ATTACHMENT 8: -

SUMMARY

OF POLLUTANT SOURCES Page 2 of 2 e. Oil Containment Oil Containment consists of the following: Maximum Tank/ Equipment Capacity (gallons)_ Physical Controls Diesel Oil Storage Tank 100,000 Diked Emergency Diesel Generator Collected in an Oil (EDG) Day Tanks 2-6,000 each Interceptor Emergency Diesel Generator 2-40,000 each None- Underground (EDG) Fuel Oil Storage Tanks There are five oil interceptors which service plant drains and sumps entering the Outfall 002 Discharge System. Those storage tanks or equipment whose containments are not directly associated with the interceptors, would ultimately be serviced by an interceptor via adjacent plant floor and service drains. The underground storage tanks listed are not serviced by oil interceptors.

2. Outfall 2 (Wastewater Treatment Plant)Sodium Bisulfite (NaHSO4) Tank The NaHSO4 tank, that is located near the station collection box, has a 900 gallon capacity and contains a 40% solution.

If any NaHSO4 is spilled during chemical delivery, it would be absorbed in the surrounding soil. Storm water contact is not likely from this location, since the area is not paved.3. Outfall 3 (Service Building 4)a. Diesel Fuel Storage Tank and Gasoline Storage Tank Used to service fleet vehicles, the diesel fuel storage tank has a 1,000 gallon capacity, and the gasoline tank has a 2,000 gallon capacity. They share the same concrete dike, which is designed to contain 115% of the total capacity.b. Chemical Waste Accumulation Area (CWAA)This outfall area has one accumulation area for automotive oils and antifreeze. This CWAA is a self-contained unit designed with a spill pan underneath.

Good Housekeeping Weekly Chemical Waste Accumulation Areas (CWAAs) and Chemical waste Storage Area (CWSA) housekeeping inspections as conducted by the Environmental personnel. Problems are corrected as they are identified. Maintenance Supervisors are assigned as responsible for various areas throughout the site. This includes cleanliness of the area.B. Preventative Maintenance Various engineers on site are assigned specific systems. The engineers are then responsible for oversight of all aspects of the system, including preventative maintenance scheduling and tracking as well as conducting weekly visual inspections. Some "systems" in this program include various chemical and oil tanks, station drainage and the oil interceptors. All preventative and scheduled maintenance items are tracked in a site-wide database.Oil interceptors are checked periodically by pumping out the associated collection tanks. These tanks rarely contain any oil, which shows that the tanks are not discharging oil to the storm water system.Warehouse and Maintenance Services personnel are trained in loading/unloading procedures and must complete Chemical Waste management training. If a spill would occur as a result of these activities, these personnel; are also trained in cleanup measures.C. Visual Inspections In addition to the system inspection by the engineer and the weekly CWAA and CESA inspections previously mentioned, a visual inspection will now be conducted by the Pollution Prevention Team on a monthly basis of all potential storm water pollutants as listed on the materials inventory. A copy of the inspection form will be maintained with this plan by Environmental. A more detailed annual inspection will also be conducted by the Storm water Pollution Prevention Team. All problems identified and the corrective actions taken will be documented in memorandum format and signed by the Manager-Site Chemistry. A copy of each annual inspection may be maintained with this plan by Environmental. ATTACHMENT 9: BEST MANAGEMENT PRACTICES Page 2 of 3 D.

Items specific to storm water spill prevention are also describes below: 1. Outfall 1 (NPDES Outfall 002)The two chemical storage buildings are diked. Although this will not contain the entire contents of either building, both have a drainage ditch with a closable gate to contain any spills.The six CWAAs are all enclosed in either a building or a plastic containment structure. Small spills would be contained in the CWAA.The three bulk chemical storage tanks have diking sufficient to contain the entire tank contents, so storm water discharge is unlikely.The 100,000 gallon diesel oil storage tank has a dike structure sufficient to hold the entire tank contents. Also, deliveries occur on a concrete pad which drains to an oil interceptor prior to discharge. The 2-40,000 gallon diesel fuel storage tanks and the Davis-Besse Administration Building diesel fuel storage tanks are underground storage tanks, so they do not come directly in contact with storm water. They are included in this plan due to the potential for a spill during bulk fuel deliveries. Salt storage is contained inside a three-sided building.All storage tank bulk deliveries are performed in the presence of site personnel. If a spill would occur, these individuals would know the required actions for responding to the incident.At Outfall 1 drainage goes through the Training Center pond prior to discharge. This is a 12 million gallon holding pond. It has a discharge gate which can be closed for cleanup actions to prevent any discharge. All large tanks contain spill kits nearby for use during spill response procedures. Such kits contain oil and chemical absorbent booms and pads, drain covers and/or plugs, and protective clothing as necessary for cleanup. ATTACHMENT 9: BEST MANAGEMENT PRACTICES Page 3 of 3 D.

2. Outfall 2 (Wastewater Treatment Plant)The sodium bisulfite tank has 900 gallon capacity and is stored in a metal building.

If any NaHSO4 is spilled during chemical delivery, it would be absorbed in the surrounding soil.3. Outfall 3 (Service Building 4)There is one CWAA in this area. It is a small plastic shed with a containment structure. Small spills would be contained in this area.There is a 1,000 gallon diesel fuel tank and a 2,000 gallon gasoline tank.These tanks and their associated pumps are contained inside a single dike structure, which is designed to contain the entire contents of these tanks. Spills are possible during fleet fueling from these tanks or during bulk deliveries. An outdoor telephone is installed nearby for contacting the control room should a spill occur. There is an oil interceptor which can contain up to 1,500 gallons.E. Sediment and Erosion Control Potential erosion areas are graded and grassy. The majority of the facility is paved or covered with gravel.F. Employee Training Applicable employees who may come in contact with spills and discharges are trained in HAZWOPER and chemical waste management.

SUMMARY

On behalf of FirstEnergy Service Company (FirstEnergy), as agent for FirstEnergy Nuclear Operating Company (FENOC), Environmental Resources Management (ERM) and Dade Moeller & Associates (Dade Moeller) conducted a Groundwater Flow Characteristics Study for the Davis-Besse Nuclear Power Station (DBNPS) located in Oak Harbor, Ohio.The purpose of the Groundwater Flow Characteristics Study was to evaluate the geology and hydrogeology at DBNPS in order to gather information necessary to design a monitoring program to minimize the potential for an unmonitored and/or undetected radioactive release to groundwater due to plant operations. Activities completed included a review of DBNPS site files, physical features, plant operating infrastructure, identification of potential areas for inadvertent radiological release, available tritium data and the site hydrogeology. This Groundwater Flow Characteristics Study is a preliminary step in the process of complying with the Nuclear Energy Institute guidance titled "Industry Ground Water Protection," dated June 2006.Historic releases of tritium to ground have been documented at DBNPS.Groundwater samples collected from existing bedrock wells within the Power Block indicated tritium in groundwater at concentrations up to 2,410 pCi/L.Potential releases from DBNPS have the potential to migrate vertically or laterally within the fill (structural or earthen), Glaciolacustrine Deposit, Till and Dolomite Bedrock towards marshes and ultimately Lake Erie.Initial evaluation of site systems, geology and hydrogeology suggest a low potential for releases to groundwater at the site to adversely impact drinking water receptors given the likely up-gradient, distant location of potential receptors and the most probable migration pathway being from the site to marshes and Lake Erie. Once in the marshes and Lake Erie, the impacts would immediately be diluted due to the volume of the groundwater discharge relative to the volume of water in the lake.Based on ERM and Dade Moeller's review of the available site data, the following recommendations are presented to monitor for inadvertent releases to groundwater at DBNPS: 1.

1.1 BACKGROUND

On behalf of FirstEnergy Service Company (FirstEnergy), as agent for FirstEnergy Nuclear Operating Company (FENOC), Environmental Resources Management (ERM) and Dade Moeller & Associates (Dade Moeller) conducted a Groundwater Flow Characteristics Study for the Davis-Besse Nuclear Power Station (DBNPS) located in Oak Harbor, Ohio (Figure 1). DBNPS contains one pressurized water reactor that was constructed in the 1970s and went on-line in November 1977.The Nuclear Energy Institute (NEI) initiated a voluntary policy in May 2006 to enhance detection, management and communication about inadvertent radiological releases in groundwater at nuclear power plants.As part of the initiative, nuclear power plants are expected to: "Put in place a company/site-specific action plan(s) to help assure timely detection and effective response to situations involving inadvertent radiological releases in groundwater to prevent migration of licensed radioactive material off-site and quantify impacts on decommissioning." This Groundwater Flow Characteristics Study for the DBNPS is a preliminary step in the process of complying with the NEI initiative.

1.2 PURPOSE

& SCOPE The purpose of the Groundwater Flow Characteristics Study was to evaluate the geology and hydrogeology at DBNPS in order to gather information necessary to design a monitoring program to minimize the potential for an unmonitored and/or undetected radioactive release to groundwater due to plant operations. The Study included a review of DBNPS site files, physical features, plant operating infrastructure, identification of potential areas for inadvertent radiological release, available tritium data and the site hydrogeology. The inter-relationship of plant operations, areas of potential concern (APCs) and estimated site groundwater flow patterns is used to develop a Conceptual Site Model (CSM) and initial groundwater monitoring strategy.ERM/DADE MOELLER 1 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 The groundwater monitoring recommendations outlined in this Groundwater Flow Characteristics Report follow NEI guidance titled"Industry Ground Water Protection," dated June 2006.1.3 LIMITATIONS This Groundwater Flow Characteristics Report (Report) provides a preliminary evaluation of site characteristics necessary to support the design of a groundwater well network for monitoring existing or potential releases of radioactivity to groundwater at the site. The professional opinions presented in this Report were developed under a limited scope, schedule and budget (ERM Proposal, 11 August 2006). This Report is intended to represent the first phase of a series of studies and activities that will be required to develop an effective groundwater monitoring program for the site. As such, the results, conclusions and recommendations in this report are subject to change as the results of successive, iterative phases of site investigation, sampling, data management, interpretation and stakeholder outreach progress.ERM/DADE MOELLER 2 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 2.0 SITE VISIT AND DATA REVIEW As part of this project, the team conducted the following activities:

3.0 FINDINGS

3.1 AREAS OF POTENTIAL CONCERN APCs represent locations at the DBNPS where there is a possibility that a release of radionuclides and/or oil and hazardous pollutants (i.e., non-radioactive contaminants) to groundwater either has, or could occur. The APCs identified at the DBNPS are summarized in Table 1 and are shown in Figure 2. Each of the primary APCs are discussed below.3.1.1 Power Block The Power Block represents the area that contains the reactor vessel and associated primary and secondary water sources in a pressurized water reactor. The Power Block includes the following APCs as potential radiological sources:* Containment Building 0 Auxiliary Building o Miscellaneous Waste Drain Tank o Spent Fuel Pool o Cask Pit o Liquid Radwaste Treatment System o Clean Waste Receiver and Monitor Tanks o Spent Resin Storage Tank o Detergent Waste Drain Tank o Boric Acid Evaporators o Concentrates Storage Tank 0 Turbine Building o East and West Condenser Pits o Sumps o Condensate Demineralizer Tanks 0 Fuel Transfer Canal* Circulating Water Pump House* Borated Water Storage Tank ERM/DADE MOELLER 5 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 0 Nitrogen and Hydrogen Supply Area 3.1.2 APCs Outside the Power Block Several radiological APCs were identified outside the Power Block as summarized below (Figure 2):* Condensate Demineralizer Tank Discharge Line -In May 1990, a break in the discharge line exiting the Condensate Demineralizer Backwash Receiver Tank was discovered east of the Power Block. Contaminated resin was released to soil at the connection between the Condensate Demineralizer Backwash Receiver Tank discharge line and a ten inch pipe that conveys the resin to South Settling Pond.* Liquid Radwaste Discharge Line -This pipe conveys liquid radiological waste from the Power Block to the Collection Box for dilution prior to release.* Collection Box -The collection box receives tritiated water from the Liquid Radwaste Discharge Line, along with water pumped up from the North and South Settling Basins. In 1997, water pumped from North Settling Basin to the Collection Box was inadvertently spilled onto the ground surface adjacent to the Collection Box.* Collection Box Discharge Pipe -This pipe is the primary discharge line for release of permitted discharge of tritiated water to Lake Erie. The discharge pipe is 72-inches in diameter and constructed of concrete.Leakage of tritiated water from the Discharge Pipe to the subsurface could result in the inadvertent release of tritium to groundwater.

• South Settling Basin (Settling Basin No. 1) -This settling pond historically received radioactive resins from the Condensate Demineralizer Backwash Receiver Tank." North Settling Basin (Settling Basin No. 2) -This settling pond is connected to the South Settling Basin via piping and pumps, allowing radioactive effluents from the South Settling Basin to enter the North Settling Basin.* Low-Level Radwaste Storage Building -This building is identified as an APC based on the handling of low-level radiological wastes in and around the building.° Dry Fuel Storage Area -This area is identified as an APC based on the handling of wastes in and around the area.ERM/DADE MOELLER 6 FIRSTENERGY-DAVIS-BESSE 55194 1/16/07
• Secondary Demineralized Water Storage Tank -Steam used to heat this outdoor tank during winter months contains tritium. This tank is an APC based on the potential for leakage from the steam system.* Fire Water Storage Tank -Steam used to heat this outdoor tank during winter months contains tritium. This tank is an APC based on the potential for leakage from the steam system.* Sanitary Wastewater Plants and Lagoon -The historic and current sanitary sewage treatment plants, associated piping and wastewater lagoon are an APC due to the potential for inadvertent co-mingling of tritiated water with the sanitary wastewater.
• Stormwater Management Systems -Impacted water has the potential to enter the any one of the three stormwater management systems and leak into groundwater through the associated catch basins, manholes and oil interceptor tanks: o Training Center Pond (NPDES Outfall 002) -Stormwater from the Power Block, several parking lots, the transmission yard and on-site ponds is routed via subsurface piping into the Training Center Pond. A stormwater outfall (NPDES Outfall 002) exits the southeast corner of the Training Center Pond to the marsh and ultimately discharges into the Toussaint River o Wastewater Treatment Plant (NPDES Outfall 601) -Treated wastewater from the sanitary wastewater plants exits the Wastewater Treatment Lagoon at NPDES Outfall 601, and then flows into the sump of the North Settling Basin. This has the potential of mixing with the water in North Settling Basin and back flowing into the Sanitary Wastewater Lagoon during periods when the discharge pumps are out of service and the North Settling Basin water level becomes high.o Service Building 4 -Stormwater from Service Building No. 4 and surrounding parking lots discharges to the marsh and ultimately Lake Erie.3.1.3 Non-radiological APCs Although the focus of the study is on potential radiological releases, the following areas were also identified as APCs for non-radiological constituents to impact groundwater quality: ERM/DADE MOELLER 7 FIRSTENERGY-DAVIS-BESSE 55194 1/16/07
• Diesel Storage Tanks -Three areas of diesel tanks represent non-radiological APCs.o A historic release of diesel fuel to soil occurred adjacent to the 100,000 gallon aboveground storage tank. This release resulted in the contamination of soil and shallow groundwater adjacent to the storage tank. Remedial activities (bioremediation and free product recovery) were conducted in response to the release.o Emergency Diesel Generator Fuel Oil Storage Tanks -Two 40,000 gallon tanks are present northwest of the Power Block.o Diesel Tank -One 6,000 gallon diesel tank is located within the Station Blackout Diesel Generator Building." Service Building No. 4 -This building is considered an APC due to the presence of an above ground gasoline storage tank and historical remedial activities related to overfilling of the tank.* Transformer Oil Collection Tank -Located north of the Power Block, an underground storage tank collects transformer oils.* Chemical Waste Storage Area -This area includes the temporary storage of drums and containers that are used to store hazardous waste and used oils including waste oil, oil filters, paints, solvents, Mineral Spirits (parts cleaner) and asbestos.* Machine Shop -Mineral spirits are used in the machine shop located at the ground level of the Personnel Shop Facility 3.2 TRITIUM DATA Historic tritium samples have been collected from potential source areas and from miscellaneous groundwater monitoring wells. Site features that represent large potential source areas of tritium include the following:
• Spent Fuel Pool -Tritium has been detected in a water sample collected from the Spent Fuel Pool at a concentration of 0.0552 microcuries per milliliter (pCi/ml).

For comparison to Environmental Protection Agency (EPA) drinking water standard of 20,000 pCi/L, this detection of 0.0552 ýtCi/ml converts to 55,200,000 picoCuries per liter (pCi/L), above the EPA standard.ERM/DADE MOELLER 8 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07

• Borated Water Storage Tank -Tritium has been detected in a water sample collected from the Borated Water Storage Tank at a concentration of 80,000,000 pCi/L.In addition to the above contained potential sources, a known release of tritium occurred in 1997, when water pumped from North Settling Basin to the Collection Box was inadvertently spilled onto the ground surface adjacent to the Collection Box. The estimated volume of water that leaked onto the ground surface was approximately 12,000 gallons. The concentration of tritium that would have been leaked to groundwater during this event can be estimated from a water sample collected in North Settling Basin on 12 May 1997, which detected tritium at 6,850 pCi/L.Groundwater monitoring efforts have included two distinct events consisting of collecting samples from existing wells. In November and January 1991, groundwater samples were collected from seven wells located near the Hydrogen Addition System near the Borated Water Storage Tank following leakage of tritiated water onto the ground surface.It is not known which seven wells were sampled, or whether the samples were collected in wells installed in the shallow or deep Dolomite Bedrock.Tritium concentrations in these seven samples ranged from 250 pCi/L to 2,410 pCi/L, with an average concentration of approximately 1,000 pCi/L.In 2004, a groundwater sample from well MW-18, located south of the Spent Fuel Pool, Cask Pit and Fuel Transfer Canal (all located within Power Block APC) was collected to evaluate tritium concentrations in groundwater nearby these potential sources. It is uncertain whether the groundwater sample was collected from the well installed in the shallow or deep Dolomite Bedrock. Tritium was detected in the groundwater sample at concentrations of 667 +/- 112 pCi/L and 728 +/- 104 pCi/L, which average to a concentration of 698 pCi/L.3.3 SITE GEOLOGY AND HYDROGEOLOGY 3.3.1 Site Geology The DBNPS site geology is primarily composed of three units, consisting of the Glaciolacustrine, Till and Dolomite Bedrock (Tymochtee Formation).

Monitoring wells, test borings and piezometers installed during construction of DBNPS indicate the relative thickness and elevation intervals for each unit in the area of the Power Block: ERM/DADE MOELLER 9 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 Unit Approximate Depth Approximate Elevation Interval(s) Below Ground Range (feet above mean sea Surface (feet below ground) level)Glaciolacustrine 0 -10 feet 574 feet -564 feet Till 10 feet -20 feet 564 feet -554 feet Dolomite Bedrock 20+ feet 554 feet and below The hydrogeologic description of each unit is described below: " Glaciolacustrine Deposit -the shallowest unit that occurs naturally at ground surface, this deposit contains inter-bedded fine sand, clayey silt and silty clay. The Glaciolacustrine Deposit represents sediments of a complex, unconsolidated nature that were deposited within a temporary lake during recession of glacial ice from Lake Erie.* Till -located beneath the Glaciolacustrine deposit, Till consists of grey, silty clay and some sand. The base of the Till is characterized by a boulder layer, which is comprised of silty sand and boulders.* Dolomite Bedrock -located beneath Till, the Dolomite Bedrock consists of argillaceous dolomite that has been subdivided into two rock types: a massive dolomite and a laminated dolomite. The massive dolomite is approximately 8-10 feet thick of hard, fine grained dolomite and is present approximately 10 feet below the top of the dolomite. Laminated dolomite occurs above and below the massive dolomite, and consists of thinly interbedded intervals of gypsum, anhydrite and shale. The upper surface of the dolomite bedrock was removed in the area of the Power Block during Unit #1 construction, and geologic mapping of the exposed bedrock surface determined jointing in bedrock with orientations to the northeast (N45°E) and northwest (N50°W). Dolomite beds within the bedrock naturally dip to the south, with the angle of dip less than one degree.The surfaces of the Glaciolacustrine, Till and Dolomite Bedrock deposits slope towards Lake Erie.' Several marshes are located between DBNPS and Lake Erie, including the Navarre Marsh section of the Ottawa National Wildlife Refuge. The marshes represent flooded areas of vegetation. The elevation of water in the marshes is generally consistent with Lake Erie, except when FirstEnergy operates pumps to control the water level on behalf of the Wildlife Refuge. The marshes are separated from Lake Erie by dikes and a barrier beach along the shoreline of Lake Erie.ERM/DADE MOELLER 10 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 3.3.2 Site Hydrogeo logy Groundwater flow in the Glaciolacustrine and Till deposits has historically been considered insignificant. Preconstruction monitoring wells were installed only in the Dolomite Bedrock, indicating that regional groundwater flow in the Dolomite Bedrock is towards Lake Erie.Groundwater flow within the Dolomite Bedrock occurs within bedding planes, joints, fractures, lineaments and solution cavities. In order to understand the direction of groundwater flow in the Dolomite Bedrock, it is critical to understand the orientation of these structural features. The predominant orientation of bedrock fractures trend from southwest to northeast. The dip of the beds within the Dolomite Bedrock is less than one percent to the south.A lineament analysis (Figure 1) depicts the orientation and/or expression of linear features at ground surface that often mimic structures in the bedrock. Such linear features in bedrock can act as preferred migration pathways for groundwater flow and contaminant transport. Figure 1 shows that the majority of surface lineaments are orientated southwest-northeast; however, additional lineaments identified beyond the limits of Figure 1 are oriented southeast-northwest. The orientation is consistent with one of the joint orientations mapped during the preconstruction excavation. Preconstruction groundwater elevation data indicated that the depth to groundwater in the Dolomite Bedrock is 2-3 feet above the elevation of water in Lake Erie.During ERM's site walk of the DBNPS, historic monitoring wells were discovered at the property (Figure 3). These monitoring wells were historically used to measure groundwater levels within shallow and deep intervals of the Dolomite Bedrock to assess the effectiveness of a dewatering system which operated during plant construction. The dewatering system included a series of pumping wells to dewater excavation areas, a grout curtain (extending 60 feet into the Dolomite Bedrock) and recharge wells to inject water back into the Dolomite Bedrock. The monitoring wells were within and outside the limits of the grout curtain to assess the effectiveness and impacts of the dewatering system during excavation activities. Static (i.e., non-pumping) groundwater elevation data from these monitoring wells were last collected in November 1979. The static measurements, which could be used to anticipate current flow conditions (i.e., no ongoing dewatering and the grout curtain presumably remain), indicate a localized mound of high groundwater elevation beneath the Power Block. The mound is present in both shallow and deep bedrock ERM/DADE MOELLER 11 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 wells. Groundwater flow directions would be orientated in a radial pattern away from the mound. 0 The presence of a mound may be related to recharge to the Dolomite Bedrock beneath the Power Block, and the presence of the grout curtain around the Power Block. The grout curtain would essentially act to retard the outer movement of groundwater flow from the Power Block. Leakage through or under the grout curtain is expected, as the average dewatering rate inside the excavation area (i.e., inside the limits of the grout curtain)during construction of Unit #1 was 350 gallons per minute.The 1979 groundwater elevation data also indicates a downward component of vertical groundwater flow (i.e., flow from shallow to deep bedrock) beneath the Power Block. South of the Power Block, the groundwater elevation data indicates a component of upward flow from deep to shallow bedrock. Given the hydrogeologic position of the DBNPS adjacent to the regional groundwater discharge body (marshes and Lake Erie), it would be anticipated that upward groundwater flow from deep to shallow bedrock would be present across DBNPS under natural conditions. The presence of downward flow conditions beneath the Power Block is likely a reflection of recharge to the Dolomite beneath the Power Block and the grout curtain around the Power Block.3.4 SURFACE WATER AND GROUNDWATER USAGE Marshes and both located east-norteafvt of the .tation, are the primary dischargelocation for grouindwater at, DBNPS. Stormwater and surface ater at D'BNPS are rouited through three different outfallsinrto tihiemarshes east of DBNPS. Lake Erie is the source of drinking water supply for communities and residents within five miles of DBNPS. The intake closest to DBNPS is Carroll Township Water Plant, located at Locus Point, approximately 3 miles northwest of the site. Lake Erie is also actively used for swimming, fishing, and other recreational activities. The Carroll Township Water Plant was activated in 1998, and offers residences near DBNPS a reliable source of quality drinking water. The intake for the Carroll Township Water Plant is approximately 1,100 feet off Locus Point, which is located approximately two miles northwest of DBNPS. Based on the most recent Radiological Environmental Operating Report, the Ottawa County Health Department has verified that there are no registered drinking water wells within five miles of DBNPS. One well located in Sand Beach (approximately

1.5 miles

NW of DBNPS) is seasonally used as a source for non-drinking water. Historically, approximately 50 percent of the houses along Sand Beach used private ERM/DADE MOELLER 12 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 wells to obtain domestic water. Other historical wells in the vicinity of DBNPS include 18 wells located within 2-3 miles of the site at the time of plant construction. Water usage from these wells was for sanitary and farm irrigation. Water quality from these wells was considered poor (i.e., high levels of carbonate, total dissolved solids and hydrogen sulfide gas)and not suitable as a source of drinking water.The areas closest to DBNPS where water supply wells were identified in the USAR are highlighted on Figure 1. The current status of these wells is not known. The areas shown on Figure 1 are located upgradient or cross-gradient from the DBNPS, with the exception of the southwestern end of Sand Beach. Water supply wells in the southwestern end of Sand Beach could potentially be downgradient of DBNPS; however, these wells are reportedly in the shallow beach sands, rather than the Dolomite Bedrock.Based on the geographic position (i.e., upgradient) of a majority of wells and shallow construction of wells at Sand Beach, releases to groundwater at the DBNPS are expected to maintain a low potential to impact nearby wells, if still in use.ERM also obtained information on registered wells from the State of Ohio Department of Natural Resources Geographic Information System (GIS)database. The only wells identified in that database included additional domestic use wells located more than one mile west of DBNPS (upgradient of the DBNPS; Figure 1).3.5 CONCEPTUAL SITE MODEL 3.5.1 Overview This section presents a CSM to describe how potential releases of contaminants at DBNPS could enter the groundwater, how they may be transported in groundwater and where transport could result in hypothetical exposure to humans or environmental receptors. The CSM acts as a working hypothesis of possible contaminant migration pathways to aid in designing an effective monitoring well network that will ultimately identify and monitor for actual groundwater impacts. Results of successive phases of field investigation conducted during well installation and subsequent monitoring are used to adjust or calibrate the CSM for site-specific conditions until the CSM is in reasonable agreement with field data. The CSM thereby validates the processes used, increasing confidence that the results obtained are a reasonable characterization of site conditions and acts as a valuable tool in stakeholder communication. ERM/DADE MOELLER 13 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 3.5.2 Plan View The CSM begins with a plan view of the DBNPS and the juxtaposition of groundwater flow paths with potential radiological and non-radiological APCs (Figure 4). Although groundwater flow in the Glaciolacustrine and Till deposits was historically believed to be minimal, there is likely a component of flow within each geologic unit. Flow within these shallow units would be largely controlled by the presence of surface water bodies (i.e., ponds, marshes and Lake Erie), as these features represent groundwater discharge bodies. Since a majority of the DBNPS is largely paved and covered by buildings, recharge to these deposits would be highest in areas west of the Power Block. The potential for leakage from plant piping and storm drains beneath paved areas could result in direct recharge of water to the Glaciolacustrine and Till deposits, or to the structural fill where native deposits were excavated during plant construction. A significant component of the plan view CSM is the regional direction of groundwater flow in the Dolomite Bedrock and localized flow influenced by the Grout Curtain. Regional flow is east-northeast towards the marshes and Lake Erie, while localized flow beneath the Power Block is represented in a radial pattern, largely controlled by the grout curtain surrounding the Power Block. Figure 4 shows there is a component of groundwater flow to the west from the Power Block; however, the ultimate discharge sink for groundwater is the marshes and Lake Erie to the east.Potential APCs falling outside the Grout Curtain and within the influence of the regional flow system include the Dry Fuel Storage Area, Wastewater Treatment Plants, Condensate Dernineralizer Backwash Receiver Tank Discharge Line, Collection Box and Discharge Pipe, Secondary Demineralized Water Storage Tank, Fire Water Storage Tank, North and South Settling Basins. Groundwater migration beneath these APCs would theoretically flow towards the closest marsh, and ultimately Lake Erie.The Discharge Pipe (72-inch concrete pipe) represents a linear APC, which is generally aligned parallel to the direction of regional groundwater flow.Potential leakage from the Discharge Pipe would likely migrate into the earthen fill surrounding the buried pipe, ultimately migrating towards the marshes south of the Discharge Pipe.ERM/DADE MOELLER 14 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07

3.5.3 Section

View The CSM includes a representation of potential radiological APCs in the context of the vertical hydrogeologic environment. The path of the cross section (shown in Figure 5) begins west of the Power Block and is orientated eastward through the Power Block. To highlight the elevation changes between the Power Block, intake canal, marshes and Lake Erie, gaps in the section were included through stretches of continuous sections of the swamp. The cross-section was developed using a 2:1 vertical exaggeration, as the vertical scale (1 inch equals 20 feet) is two times smaller than the horizontal scale (1 inch equals 40 feet). Figure 5 shows the base elevation of the excavation area, station buildings, native geologic units, excavation backfill units, existing monitoring wells, wave protection dikes and DBNPS infrastructure. The cross-section indicates that the excavation for the Power Block extends into the Dolomite Bedrock. The elevations of groundwater in the Dolomite Bedrock and Lake Erie are higher than the base elevation of buildings within the Power Block.Although DBNPS construction reports indicate that the Glaciolacustrine and Till units are not water bearing, ERM/ Dade Moeller's experience indicates that till can support groundwater flow and transport of contaminants. This characterization has been observed at other sites where the migration of tritium in a till aquifer occurred in a boulder layer located within a till. Boulder layers represent discrete intervals of higher hydraulic conductivity and porosity over bulk sediments within a till. An additional migration pathway for contaminants in till includes fractures within the till, which could develop in response to the rebound of land surface following the retreat of glacial ice that was responsible for deposition of the Glaciolacustrine deposit.Analysis of DBNPS excavation depths and building components (Figure 5) yields important considerations regarding the potential for leakage of radionuclides to the structural fill, Till and Dolomite Bedrock. These observations are summarized as follows: 0 Vertical migration of tritiated water to the structural backfill is possible where radiological sources within the Power Block immediately overlie the structural fill. (Figure 5). For example, leakage of tritiated water from the Borated Water Storage Tank and Condensate Demineralizer Backwash Receiver Tank or 3-inch Radwaste Discharge Line (not shown in Figure 5) could release radionuclides to the structural fill. Once in the structural fill, migration from these sources ERM/DADE MOELLER 15 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 would be anticipated towards the east, or potentially downward to the Dolomite Bedrock.* Vertical leakage from the 72-inch Discharge Pipe could result in leakage to the earthen backfill surrounding the concrete pipe. A release through the Discharge Pipe would be anticipated to ultimately migrate in a southeast direction towards the marsh adjacent to the Discharge Pipe." Vertical leakage directly to the Dolomite Bedrock is possible through releases at sumps and floor drains within the Containment Building, Auxiliary Building and Turbine Building that are constructed directly over Dolomite Bedrock. Migration from these potential sources would be anticipated to be outward from the Power Block, and possibly to deeper bedrock. Once in the Dolomite Bedrock and outside the influence of the Power Block and grout curtains, tritium would likely migrate to the east towards Lake Erie, corresponding with the direction of regional groundwater flow.3.5.4 Summary Potential releases of tritium from DBNPS are anticipated to migrate vertically or laterally within the fill (structural and earthen), Glaciolacustrine Deposit, Till and Dolomite Bedrock. Migration within these units would be towards marshes that are located between the Power Block and Lake Erie, with Lake Erie representing the regional groundwater discharge point. Initial evaluation of site systems, geology and hydrogeology suggest a low potential for releases to groundwater at the site to adversely impact drinking water receptors given the likely up-gradient, distant location of potential receptors and the most probable migration pathway being from the site to marshes and Lake Erie. Once in marshes and/or Lake Erie, the impacts would immediately be diluted due to the volume and concentration of naturally-occurring tritium in the lake.ERM/DADE MOELLER 16 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07

4.0 RECOMMENDATIONS

Based on ERM and Dade Moeller's review of the available site data, the following recommendations are provided to support development of an effective groundwater monitoring program at the DBNPS: 1. Inventory and Monitor the Existing Well Network DBNPS has an extensive network of monitoring wells outside the Power Block. The wells, installed during excavation of Unit #1 and planned Units #2 and #3, provide a starting point for the development of a groundwater monitoring well network at the site. The existing monitoring wells should be inspected to evaluate their current condition and suitability for use as groundwater monitoring wells.Wells that are deemed suitable should be surveyed and then incorporated into the groundwater monitoring program. This work should be conducted prior to installation of additional monitoring wells to further guide the selection and placement of new wells. This evaluation should also focus on the extent to which existing wells may act as preferential pathways for contaminant migration to identify those wells that should be properly abandoned.

2. Develop an Integrated Monitoring Program DBNPS should consider developing a program to collect groundwater level measurements from suitable existing wells. The program should include monitoring on a quarterly basis, to evaluate the seasonal effects on groundwater flow elevations and directions.

In addition, the program should incorporate measurements of surface water in nearby marshes to fully integrate the groundwater and surface water interactions at DBNPS. The sampling of the surface water within each marsh, on-site ponds, and Lake Erie and gauging surface water and groundwater elevations simultaneously should also be incorporated into the sampling program.In order to evaluate the potential contribution of gaseous emission washout on tritium levels, DBNPS should monitor tritium in atmospheric water vapor and/or precipitation at indicator and control locations. This data should be combined with the monitoring program to develop and integrate knowledge of tritium discharges to groundwater. ERM/DADE MOELLER 17 FIRSTENERGY-DAVIS-BESSE 55194 1/16/07

3. Install and Sample Monitoring Wells The following table summarizes recommended locations and target units for potential installation of new groundwater monitoring wells for the DBNPS site. The wells are shown in Figure 4. The number of these locations selected for installation should be re-evaluated based on the inventory of existing wells and sampling and gauging results obtained and the results of additional site source evaluation.

Monitoring locations may need to be added or deleted as results are obtained and the CSM is refined.Well Location Construction and Rationale A West of Well Triplet Power Block" Shallow -monitor background conditions" Mid -monitor background conditions

For example, drilling successively deeper into the subsurface can result in advertent communication of shallow and deep aquifers if precautions are not incorporated into the drilling program.This cross-communication is also referred to as cross-contamination in the event that shallow contamination is brought to deeper depths that were previously not impacted. There are a variety of drilling techniques that could be utilized at the site that should be evaluated with regard to time, cost, integrity of well, ability to collect soil and groundwater samples during installation, minimization of worker exposure and generation of wastes requiring management and disposal.In addition to the monitoring wells, the following temporary grab groundwater samples are recommended to allow field screening of groundwater quality at each location: ERM/DADE MOELLER 19 FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 Temporary Grab Groundwater Description and Rationale Location East of Outfall 3 One shallow grab sample -monitor Outfall 3 South of Eight Shallow samples -monitor 72-inch Concrete Discharge Line Discharge Line (grab samples collected every 100 feet along the length of the Discharge Line)East of North One shallow sample -monitor North Settling Basin Settling Basin East of South One shallow sample -monitor South Settling Basin Settling Basin East of Sanitary One shallow sample -monitor Sanitary Lagoon Lagoon East of Current One shallow sample -monitor the Current Sewage Sewage Treatment Plant Treatment Plant Training Center Two shallow samples -monitor the Training Center Pond Pond Temporary grab groundwater samples are collected using a discrete interval drive point sampler to allow collection of shallow groundwater samples for laboratory analysis. The technology is very effective as a screening tool for evaluating groundwater quality in areas of low likelihood of groundwater impact and over a larger area (i.e. approximately 800 feet of Discharge Line). The screening data from the grab groundwater samples is used to focus later investigations, including the installation of permanent monitoring wells.During the field component of the groundwater investigation program, the intervals for monitoring well screens and depths for grab samples should be based on field observations and testing conducted during boring advancement. Since geologic deposits are inherently heterogeneous, the depth of well screens and sample depth should correspond with the most permeable intervals, rather than a predetermined depth. The ability to adapt and modify screen settings and target depths based on field data will allow for a representative well network for monitoring potential inadvertent releases.4. Develop a Quality Assurance Project Plan All the components of a groundwater monitoring program should be addressed in a Quality Assurance Project Plan (QAPP) specifically ERM/ DADE MOELLER 20 FIRSTENERGY-DAVIS-BESSE 55194 1/16/07 designed to address potential groundwater issues at the site. DBNPS monitoring programs (i.e., REMP and tritium tracking) should have consistent Lower Levels of Detection (LLDs) and reporting criteria.Consideration should be given to the required sensitivity for tritium monitoring in groundwater. DBNPS monitors to 330 pCi/L, and the State of Ohio monitors to 300 pCi/L. Looking forward to public communication of the new groundwater monitoring data, it would be prudent to coordinate the sensitivities of the measurements so as to make data comparable among the stakeholders. It may also be prudent to report some data in dual units (i.e., ptCi/ml and pCi/L) to facilitate comparisons and eliminate confusion.

5. Define Internal and External Reporting Requirements As data are collected, it is important that the thresholds and timeframes for internal and external reporting purposes be clearly defined. A written summary of the internal and external reporting requirements, including NRC, NEI and State of Ohio criteria, for all parameters that will be monitored should be developed to support the implementation of the groundwater monitoring program. The reporting requirements should be applied consistently across FirstEnergy's three nuclear power plants.6. Develop a Communication Plan Stakeholder communication is a key component of the NEI initiative.

Therefore, a communication plan should be developed to identify and define the stakeholders related to the tritium in groundwater issue and to determine who is responsible for the various types of communication and how the results will be communicated. As with the reporting requirements, the communication plan should be developed consistently across FirstEnergy's three nuclear power plants.ERM/DADE MOELLER FIRSTENERGY -DAVIS-BESSE 55194 1/16/07 ERM/DADE MOELLER 21 FIRSTENERGY -DAVIS- BESSE 55194 1/16/07 Tables Table 1 Areas of Potential Concern Davis-Besse Nuclear Power Station Oak Harbor, OH Category Area of Potential Concern Radiological -Power Block Containment Building Auxiliary Building Miscellaneous Waste Drain Tank Spent Fuel Pool Cask Pit Turbine Building East and West Condenser Pits Sumps Condensate Demineralizer Tanks Fuel Transfer Canal Circulating Water Pump House Borated Water Storage Tank Nitrogen and Hydrogen Supply Piping Radiologial -Outside Power Block Condensate Demineralizer Tank Discharge Line Liquid Radwaste Discharge Line Collection Box Collection Box Discharge Pipe South Settling Basin (Settling Basin No. 1)North Settling Basin (Settline Basin No. 2)Low-Level Radwaste Storage Building Dry Fuel Storage Area Secondary Water Demineralized Water Storage Tank Fire Water Storage Tank Sanitary Wastewater Plants Stormwater Management System NPDES Outfall 002 (Training Center Pond)NPDES Outfall 601 (Wastewater Treatment Plant)Service Building No. 4 Non-Radiological Diesel Storage Tanks Service Building No. 4 (Gasoline Tank)Transformer Oil Collection Tank Chemical Waste Storage Area Machine Shops 0 Tables 0 0 Table 1 Areas of Potential Concern Davis-Besse Nuclear Power Station Oak Harbor, OH Category Area of Potential Concern Radiological -Power Block Containment Building Auxiliary Building Miscellaneous Waste Drain Tank Spent Fuel Pool Cask Pit Turbine Building East and West Condenser Pits Sumps Condensate Demineralizer Tanks Fuel Transfer Canal Circulating Water Pump House Borated Water Storage Tank Nitrogen and Hydrogen Supply Piping Radiologial -Outside Power Block Condensate Demineralizer Tank Discharge Line Liquid Radwaste Discharge Line Collection Box Collection Box Discharge Pipe South Settling Basin (Settling Basin No. 1)North Settling Basin (Settline Basin No. 2)Low-Level Radwaste Storage Building Dry Fuel Storage Area Secondary Water Demineralized Water Storage Tank Fire Water Storage Tank Sanitary Wastewater Plants Stormwater Management System NPDES Outfall 002 (Training Center Pond)NPDES Outfall 601 (Wastewater Treatment Plant)Service Building No. 4 Non-Radiological Diesel Storage Tanks Service Building No. 4 (Gasoline Tank)Transformer Oil Collection Tank Chemical Waste Storage Area ,Machine Shops Figures 0 Legend Reside ntiallCom mercia I Wl11s Unknonm!

This description should provide reasonable assurance that any system leakage will be properly contained and processed prior to its release to the environment. Response #1 Sumps in the Auxiliary building collect liquid from floor and equipment drains in rooms containing contaminated systems. All sumps discharge to the miscellaneous waste drain tank (MWDT). There are several areas with the auxiliary building that contain floor drains which discharge directly to the MWDT without going into a sump. These rooms in the auxiliary building contain systems that interface directly with the reactor coolant system. The systems are High Pressure Injection, Low Pressure Injection/Decay Heat, Decay Heat Coolers, Containment Spray, and the Makeup System. Leakage from any of these systems will therefore be contained in the MWDT. Liquids collected there are processed as described below.The detergent waste drain tank (DWDT) is also located within contaminated areas. It receives influent from the laundry facility and various other floor drains in the auxiliary building. This tank discharges to the miscellaneous waste monitor tank and is processed as described below.A past primary to secondary coolant leak has cause the station to conservatively declare all feedwater, condensate, and auxiliary steam systems in the turbine building as potentially contaminated. Therefore, all rooms containing these systems are considered potential sources of contaminated water leakage into the turbine building sumps and drains system.The Component Cooling Water (CCW) System Heat Exchangers are cooled by the Service Water (SW) System. Due to past leakage from the Letdown Coolers, the CCW system is considered to be contaminated. If a leak were to develop in the CCW Heat Exchangers, the contamination could reach Lake Erie through the discharge from the Collection Box. The Collection Box discharge line contains a radiation monitor. Any leakage from the CCW System would be identified by loss of inventory in the CCW Surge Tank.Question #2 -Describe the normal liquid effluent pathway, including the downstream discharge pathway such as circulating water or river water.Response #2 Question 2.a -Where does the liquid waste discharge to? Response 2.a -Sumps in located throughout the plant collect drainage from equipment and floor drains and discharge to one of several places: (1) Turbine Building East and West Condenser Pits -These sumps are routed to the settling basins. The settling basins are sampled and are released to the collection box outfall to Lake Erie. Weekly samples are taken using procedure DB-CN-04039 to insure radioactivity is within applicable limits including a tritium analysis. A list of potential tritium sources is attached.(2) Turbine Building -Sumps and drain risers discharge to the storm sewer system which goes to the training center pond, a marsh pond, and ultimately to the Touissaint River. The inlet to the training center pond and the marsh pond are sampled weekly for tritium and other radioactivity. A list of potential tritium sources is attached.(3) Auxiliary building -Sumps that are in contaminated/radioactive areas discharge to the miscellaneous waste drain tank (MWDT). This tank is processed to the miscellaneous waste monitor tank (MWMT) through a demineralizing skid. It is then recirculated in the MWMT and sampled in accordance with 1OCFR20, the Offsite Dose Calculation Manual, and Operations Procedure DB-OP-03011. When it is determined acceptable, the liquid is discharged to the collection box outfall to Lake Erie. A composite sample from each batch release is collected in accordance with DB-OP--0301 1, Radioactive Liquid Batch Release, Step 4.18.3 for monthly tritium analysis as required by DB-CN-03012, Liquid Releases, Monthly Monitoring Analysis. The monthly composite is analyzed in accordance with DB-CH-0 1804, Tritium Determination, to achieve a Lower Limit of Detection of I x 10-5 uCi/ml. The tritium activity from the composite sample is entered into the RETSCode program which calculates the tritium released for each batch release for the month.Question 2.b -Does the liquid waste discharge line traverse any non-license owned areas?Response 2.b -The liquid waste discharge line is contained on the licensee owned properties. Reference drawings: C-46, C-49 and C-52 Question 2.c -Are there any vacuum breakers or relief valves on the discharge piping and are they monitored for potential leakage?Response 2.c -There are no vacuum breakers or relief valves on the discharge piping.Question # 3 -Provide a description of the spent fuel pool, including liner construction and leakage monitoring. Identify any vulnerability to an unmonitored release. Response # 3 -A description of the spent fuel pool, including liner construction and leakage monitoring is as follows: The SFP stores irradiated fuel assemblies under water. The spent fuel racks are sized to store 1624 spent fuel assemblies. The SFP is connected to the Fuel Transfer Canal via an 80001b gate and gateway. An identical gate arrangement exists between the SFP and the Cask pit. The Fuel Transfer Canal is connected to the refueling canal via two 30-inch-outer diameter fuel transfer tubes. The SFP is flooded to 23 feet of water over the top of the irradiated fuel assemblies seated in the storage racks (pool surface Elevation 601' 6").The spent fuel pool, fuel transfer pit, cask pit, liners, and all supporting structures are designed for seismic loads.The 5' thick south wall of the Spent Fuel Pool (SFP) and Cask Pit (CP) form the outside wall of the Auxiliary Building. Much of the flooded portion of the SFP and CP are below grade and not visible. There is a waterproof membrane on this outside wall and under the building foundation (ref. DWG C-202 and C-230) to keep outside groundwater from leaching into the Auxiliary Building. This membrane would also likely act to keep any potential fuel pool leakage from escaping into the soil.The fuel pool, fuel transfer pit, and cask pit are lined with stainless steel and equipped with a leak chase system and tell-tale drain connections for leakage detection. Procedure DB-SP-04400, Spent Fuel Pool, Fuel Transfer Pit, and Cask Pit Leak Detection System Test, is performed monthly to quantify a leak rate from the 21 leak chases. Leakage is detected during this monthly test from several of the leak chases. The highest leak rate is approximately 1.5 ml/min.Tritium concentration in the SFP is 0.0552 uCi/mL based on the latest sample. A groundwater sample was obtained from an existing monitoring well located near the south wall of the SFP in 2004. The test results using site equipment were inconclusive as the values measured were at the minimum detectable levels of the site's equipment. A portion of this sample was sent off-site and tested by Environmental Inc. The values were 667 +/- 112 pCi/L and 728 +/- 104 pCi/L. These values are substantially below those measured at other plants with known fuel pool leakage. A PM activity was created to perform sampling from this monitoring well every 5 years.Question # 4 -Identify those contaminated tanks, below above and below grade, located outside of plant structures (i.e., outside of plant drainage/sump system). Identify the run-off pathway to the environment. Response # 4 -The following tanks are contaminated tanks, located outside of plant structures with the run-off pathways to the environment identified: The Borated Water Storage Tank (BWST) is a contaminated tank above grade and located outside of plant structures. The tank base is surrounded by gravel. Tank overflow is routed to the Miscellaneous Waste Drain Tank. Tank leakage would be onto to the gravel and into the ground surrounding the tank. Some tank leakage may be collected into the storm sewer system and directed to the Training Center pond and, ultimately, into the Touissaint River. Tritium concentration in the BWST is 0.08 uCi/mL based on the latest sample.The Demineralized Water Storage Tank and Fire Water Storage Tank are above grade and located outside of plant structures. Both are provided with steam heaters to maintain temperature during winter months. The steam provided to these heaters is contaminated. If a leak were to develop in the heater, the water in the tank could become contaminated. Tank overflow or leakage would be onto to the pavement or gravel and into the ground surrounding the tank. Some tank leakage may be collected into the storm sewer system and directed to the Training Center pond and, ultimately, into the Touissaint River.Several small pipes connect the nitrogen and hydrogen supply systems to various contaminated systems and components (P&ID M-0 19 and 044). The nitrogen and hydrogen supply tanks are located outside of plant structures. Back leakage through valves could result in contaminated water entering these pipes. Leakage of this contaminated water from these pipes would be onto the gravel or into the ground. Some pipe leakage may be collected into the storm sewer system and directed to the Training Center pond and, ultimately, into the Touissaint River.

SUMMARY

On behalf of FirstEnergy Nuclear Operating Company (FENOC), Environmental Resources Management (ERM) has prepared this Groundwater Monitoring Well Installation and Monitoring Report to document the development of a groundwater monitoring program at the Davis-Besse Nuclear Power Station (DBNPS) located in Oak Harbor, Ohio.The purpose of the groundwater program is to assess whether there have been any inadvertent radiological releases from the Power Block that may have impacted site groundwater or have the potential to migrate toward Lake Erie or any other human or environmental receptor.Activities completed included an inventory and assessment of existing site wells, the installation of five groundwater monitoring well triplets and a water table well (i.e., 16 new wells), the preparation of groundwater field sampling plans, the sampling of groundwater monitoring wells (three events), and the evaluation of groundwater monitoring results in the context of the hydrogeologic regime.The key findings from the groundwater investigation include the following: Geology* The surficial geology beneath the DBNPS consists of Glaciolacustrine and Till units. The Glaciolacustrine unit is characterized as cohesive, brown silt with some sand and clay. The Till is characterized as brown to dark-gray, silty clay.* Beneath the Till is Dolomite Bedrock, subdivided into a Laminated Dolomite and a Massive Dolomite. The Laminated Dolomite, which is encountered above and below the Massive Dolomite, contains thin layers of interbedded dolomite, gypsum, anhydrite and shale. The Massive Dolomite is approximately 10 feet thick, hard, finely grained, and located approximately 10 feet below the top of the Dolomite.Historic Well Inventory A total of 54 wells (27 couplets) were located and inspected during the well inventory and 24 wells (12 couplets) could not be found.Each well couplet consists of a shallow and deep well within the ERM/DADE MOELLER ES-1 FIRSTENERGY -DAV&BESSE 65992.2 18 MAR 08 Dolomite Bedrock. The shallow bedrock well is screened within the Upper Dolomite and the deeper bedrock well is screened in the Lower Dolomite. The Massive Dolomite unit separates wells screened within the Upper and Lower Dolomite.The historic wells, by themselves, were not sufficient to create an effective groundwater monitoring program at DBNPS because they did not provide adequate lateral and vertical coverage. In addition, due to the age of the wells, their construction quality and subsurface conditions are not known.Groundwoater Flow" The ability to develop groundwater elevation contours and flow patterns is complicated by several factors, including the presence of a grout curtain, the flow of groundwater within discrete fractures in bedrock, the large area of excavated bedrock beneath the Power Block and the high degree of mineralized groundwater and associated low yield observed in the new Lower Dolomite wells.An additional uncertainty is the usability of historic elevation survey data that were used to calculate groundwater elevations from the historic wells." Based on the distribution of groundwater elevations, groundwater flow in the Till, Upper Dolomite and Lower Dolomite units is from west to east across the site.* The ultimate discharge point for groundwater in the Till, Upper Dolomite and Lower Dolomite is the marshes and/or Lake Erie east of the Power Block.Groundwater Quality" Strong hydrogen sulfide odors were noted in site groundwater, particularly new Lower Dolomite wells MW-101C, MW-102C, MW-103C and MW-104C located east of the Power Block. The hydrogen sulfide is believed to be naturally occurring and caused by the weathering of gypsum and anhydrite minerals. Groundwater field parameters at these wells are characterized by high specific conductance, low ORP and high turbidity water." High hydrogen sulfide gas levels at wells MW-101C, MW-102C, MW-103C and MW-104C may be inadvertently trapped due to the use of expansion plugs at these wells. The sulfide gas may limit the ERM/DADE MOELLER ES-2 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 ability for the well screen to communicate with the Lower Dolomite. Future modifications to the expansion plugs to allow venting of the sulfide gas will be evaluated in effort to obtain more accurate groundwater elevation data from these wells.Reported concentrations of tritium in groundwater between 178 pCi/L and 348 pCi/L represent statistically insignificant activity at the 95% confidence level and are considered representative of local background conditions. Factors influencing local background condition may include the historic atmospheric bomb testing program, cosmic ray interactions in the earth's atmosphere and localized washout from continuous and batch gaseous releases from DPNBS. Reported values above 348 pCi/L represent concentrations that are statistically greater than local background conditions." Tritium concentrations above the 348 pCi/L background value were located primarily in monitoring wells east of the Power Block.* Tritium concentrations in the wells screened in the Till ranged from less than the minimum detectable concentration (MDC; <193 pCi/L) to 1,832 pCi/L. The highest concentrations were detected down-gradient (northeast) of the Power Block, including MW-102A (387 pCi/L), MW-103A (495 pCi/L), and MW-105A (1,832 pCi/L)." Tritium concentrations in the wells screened in the Upper Dolomite ranged from less than the MDC (<193 pCi/L) to 7,535 pCi/L. The highest concentrations were detected down-gradient (east) of the Power Block, including MW-31S, MW-32S, MW-33S, MW-34S, MW-37S and MW-30S. Two detections above local background conditions were detected at well MW-30S (1,307 pCi/L) and well MW-37S (2,961 pCi/L), located north of the Power Block.* Tritium concentrations in the wells screened in the Lower Dolomite ranged from less than the MDC (<193 pCi/L) to 3,271 pCi/L. The highest detections were located east/southeast of the Power Block, including wells MW-33D, MW-34D and MW-12D.* No gamma emitting radionuclides were detected above MDC in any of the groundwater samples collected during the June, July/August 2007 or the September/October 2007 monitoring events.ERM/DADE MOELLER ES -3 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08

• Tritium concentrations in groundwater during the June, July and August and September/October 2007 monitoring events were below the Environmental Protection Agency's drinking water standard of 20,000 pCi/L.Updated CSM" Groundwater flow within the Till, Upper Dolomite and Lower Dolomite units at DBNPS is generally from west to east toward Lake Erie with groundwater discharge to the marshes and/or Lake Erie." Potential inadvertent releases from within the Power Block, including the Spent Fuel Pool, would migrate vertically down through the unsaturated zone to the water table. Potential releases from structures below ground could release tritium directly to the Upper or Lower Dolomite unit.* Elevated detections in Upper Dolomite wells MW-31S and MW-32S are located on reported southwest to northeast fractures that project back to the Power Block." Tritium in groundwater will ultimately migrate into Lake Erie, where the concentrations will be diluted due to the volume of groundwater discharge versus the volume of water in the lake." Historic monitoring of Lake Erie by DBNPS indicates that there have been very few detections of tritium above local background conditions, and they are not likely to have been caused by groundwater contributions.

Based upon the above findings, FirstEnergy should further evaluate the hydrogeology and influence of plant features on site groundwater flow.In addition, tritium detections above local background conditions should be evaluated to establish a reliable monitoring well network for long-term monitoring.

1.0 INTRODUCTION

On behalf of FirstEnergy Nuclear Operating Company (FENOC), Environmental Resources Management (ERM) has prepared this Groundwater Monitoring Well Installation and Monitoring Report to document the development of a groundwater monitoring program at the Davis-Besse Nuclear Power Station (DBNPS) located in Oak Harbor, Ohio (Figure 1).The groundwater monitoring program was implemented to comply with the Nuclear Energy Institute's (NEI) Groundwater Protection Initiative, dated August 2007. The Groundwater Protection Initiative was developed to enhance the detection, management and communication of inadvertent radiological releases to groundwater at nuclear power plants. As part of the initiative, nuclear power plants are expected to: "Put in place a company/site-specific action plan(s) to help assure timely detection and effective response to situations involving inadvertent radiological releases in groundwater to prevent migration of licensed radioactive material off-site and quantify impacts on decommissioning." (NEI, May 2006).As a first step toward the completion of its action plan, FENOC hired ERM and Dade Moeller & Associates (Dade Moeller) in 2006 to conduct an evaluation of potential radiological sources and groundwater flow at DBNPS. Results of this study were presented in a report titled Groundwater Flow Characteristics Report -Davis-Besse Nuclear Power Station, Oak Harbor, Ohio (ERM, 16 January 2007). The January 2007 report provided an overview of DBNPS physical features, plant operating infrastructure, potential areas of radiological releases, available tritium data and site hydrogeology.

1.1 BACKGROUND

1.1.1 Site History DBNPS consists of a pressurized water reactor unit that was constructed in the 1970s and went on-line in November 1977. The facility is located on a 954-acre parcel of land that abuts a National Wildlife Refuge and Lake Erie. An intake canal, which provides cooling and process water to ERM/DADE MOELLER 1 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 DBNPS, is located 250 feet east of the Power Block and is hydraulically connected to Lake Erie.1.1.2 Prior Findings The Groundwater Flow Characteristics Report presented a Conceptual Site Model (CSM) describing potential source areas, migration pathways and both human and environmental receptors at DBNPS. The CSM considered site physical features and included the following key findings: 1. Radiological areas of potential concern (APCs) at DBNPS, defined as locations where a release of radionuclides to groundwater has, or could occur, include the Power Block, Low Level Radiological Waste Storage Building, Dry Fuel Storage Area, Training Center Pond NPDES Outfall 002, Sewage Treatment Plants (abandoned and operating), NPDES Outfall 001, Sanitary Lagoon, North and South Settling Basins, Collection Box Discharge Pipe, Collection Box, Liquid Radwaste Discharge Line, Condensate Demineralized Water Storage Tank, Secondary Demineralized Water Storage Tank, Fire Storage Tank, and Service Building 4 Outfall (Figure 2).2. Inadvertent releases from DBNPS have the potential to migrate vertically through the fill (structural or earthen), Glaciolacustrine unit, Till unit and Dolomite Bedrock.3. The basement of buildings within the Power Block extends down into excavated portions of the Dolomite Bedrock. Potential inadvertent releases at depth from within the Power Block could discharge directly to the Dolomite Bedrock.4. Regional groundwater flow is from west to east-northeast towards the marshes and Lake Erie. The ultimate discharge sink for groundwater is the marshes and Lake Erie east of the property.5. Initial evaluation of site systems, geology and hydrogeology suggest a low potential for releases to groundwater at the site to adversely impact drinking water receptors given the likely up-gradient, distant location of potential receptors and the most probable migration pathway being from the Power Block to the marshes and Lake Erie.6. Concentrations of tritium in groundwater would be diluted at the marsh and Lake Erie due to the large volume of surface water relative to the volume of groundwater discharge.

1.2 PURPOSE

& SCOPE The purpose of this Groundwater Monitoring Well Installation and Monitoring Report is to document the development of a groundwater monitoring program at DBNPS. The groundwater monitoring program is intended to assess whether any inadvertent release from the Power Block has the potential to migrate toward the adjacent marshes and/or Lake Erie or any other human or environmental receptor. The program was implemented using a phased approach, including the use of historic and new wells to collect groundwater samples. The intrusive investigations followed an outside-in, top-down approach to address gaps identified in the CSM.The following activities were completed during development of the groundwater monitoring program: " inventory of historic wells;" preparation of groundwater field sampling plans;" screening and confirmatory groundwater sampling of historic monitoring wells;* installation of five well triplets and a water table well (i.e., 16 new wells);" groundwater sampling of comprehensive monitoring well network (three rounds);* survey of well reference measuring points for determination of groundwater elevations;

• evaluating groundwater elevations and flow directions; and* evaluating groundwater monitoring results in the context of the hydrogeologic regime.The groundwater monitoring program was developed using a team of contractors, including the following:

2.0 METHODOLOGY

2.1 INVENTORY

& MONITORING OF HISTORIC WELLS 2.1.1 Well Inventory & Gauging On 9 and 10 May 2007, ERM conducted a site visit to inspect historic monitoring wells at DBNPS and to determine if those wells were potentially suitable for use as part of the plant groundwater monitoring program. The well inventory included a site walk to locate the monitoring wells and conduct the following activities:

• confirm the well location and designation against historic documents;
• collect spatial coordinates using a hand-held global positioning system device;" assess the physical condition of the monitoring well;* establish a measuring point for future depth to groundwater measurements;" measure the well diameter, depth to groundwater and total depth;and" attach an identification tag to the monitoring well.Physical measurements and observations made during the well inventory were tabulated (Table 1) and compared to historic documentation.

Results of the well inventory were used to determine which historic monitoring wells were appropriate to use in future groundwater monitoring activities. 2.1.2 June 2007 Groundwater Monitoring Event Upon completion of the well inventory, a Groundwater Field Sampling Plan (FSP) (ERM, 8 June 2007) was prepared to outline procedures for groundwater sampling at select historic monitoring wells. The purpose of the FSP was to document the sampling locations, methodologies, analytical techniques and quality assurance/ quality control (QA/QC)measures for the collection of representative groundwater samples.ERM/ DADE MOELLER 5 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 The purpose of the June 2007 monitoring event was to conduct a preliminary (or screening) round to evaluate the potential for tritium and gamma emitting radionuclides in groundwater and to support final selection of the new monitoring well locations. Sampling locations represented a subset of the historic monitoring wells at the property. The rationale for selecting the wells is included in Table 2.Groundwater samples were collected using low-flow methodologies as described in the FSP. Sampling depths were specified for each well as the mid point of the saturated screened interval. Quality Assurance/Quality Control (QA/QC) procedures were specified for both the field and analytical program.From 11 to 27 June 2007, BETA Laboratory personnel conducted groundwater monitoring at 17 historic monitoring wells: MW-1S, MW-1D, MW-7S, MW-12S, MW-15S, MW-15D, MW-18S, MW-18D, MW-20S, MW-20D, MW-26S, MW-26D, MW-30S, MW-32S, MW-32D, MW-33S, and MW-33D.On 11 June 2007, prior to sampling, the depth to groundwater was measured in each well using an electric water level meter. Low-flow samples were collected using a peristaltic pump with disposable tubing.During low-flow purging, geochemical field parameters were measured with an in-line flow-through-cell at regular intervals for stabilization criteria. Field parameters included temperature, specific conductivity, pH, dissolved oxygen (DO), and oxidation-reduction potential (ORP). The geochemical field parameters were recorded using a multi-parameter water quality instrument that was calibrated at the beginning of each day.Turbidity samples were collected upstream of the flow-through-cell and analyzed using a field turbidity meter. After stabilization of the field parameters, the flow-through-cell was disconnected and a groundwater sample was collected. All field information and parameters were recorded on Low-Flow Groundwater Sampling forms and observations were recorded in a log book.Water samples were collected in one-liter containers. No filtration or preservation was performed or required. All samples were packaged and shipped under chain-of-custody procedures to MidWest Laboratory of Northbrook, Illinois for analysis of Tritium (EPA Method 906.0) and gamma emitting radionuclides (EPA Method 901.1). Gamma isotopes included manganese-54 (Mn-54), iron-59 (Fe-59), cobalt-58 (Co-58), cobalt-ERM/ DADE MOELLER 6 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 60 (Co-60), zinc-65 (Zn-65), zirconium-niobium-95 (Zr-Nb-95), cesium-134 (Cs-134), cesium-137 (Cs-137) and barium-lanthanum-140 (Ba-La-140). QA/QC procedures during the June 2007 monitoring event included field and laboratory methods to assess the overall analytical results. QA/QC procedures included collection of the following additional samples (Table 3): " Field duplicate (FD) -a QA/QC sample collected and analyzed to evaluate analytical precision. Two duplicate samples were collected in June 2007 (MW-12S and MW-20S). The duplicate samples were submitted for analysis; however, the duplicates were labelled with unique names (i.e., DBD-01 as a duplicate of sample MW-12S and DBD-02 as a duplicate of MW-20S), such that the laboratory was not aware of the sample's origin. (i.e., these were blind duplicate samples).* Matrix Spike/Matrix Spike Duplicate (MS/MSD) -a QA/QC sample collected and analyzed to evaluate the potential for matrix interferences on analytical accuracy. Matrix spike and matrix spike duplicate samples were collected at MW-26D by collecting two additional samples. The June 2007 samples were spiked at the laboratory with standards of 5,639 pCi/L of tritium, 59.3 pCi/L of cesium-134 and 66.3 pCi/L of cesium-137 and analyzed to compare the analytical results to the spike concentration. 2.2 JULY/AUGUST 2007 GROUNDWATER MONITORING EVENT Upon receipt of the June 2007 groundwater monitoring results, an additional round of groundwater monitoring was performed to confirm the June results and to aid in finalizing the location of the proposed monitoring wells.Groundwater samples were collected using low-flow methodologies as described in the June 2007 FSP. Sampling depths were specified for each well as the mid point of the saturated screened interval. QA/QC procedures developed for the June sampling event were followed.From 31 July to 6 August 2007, BETA Laboratory personnel conducted groundwater monitoring at 14 historic monitoring wells:* Re-sampled wells: MW-12S, MW-30S, MW-32S, MW-32D, MW-33S, MW-33D; and ERM/DADE MOELLER 7 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08

• Additional sampled wells: MW-12D, MW-30D, MW-31S, MW-31D MW-34S, MW-34D, MW-37S, and MW-37D.On 31 July 2007, prior to sampling, the depth to groundwater was measured in each well using an electric water level meter. Low-flow samples were collected using a peristaltic pump with disposable tubing.Purging, measurement of field parameters and sample collection for laboratory analysis in July/August 2007 were performed in a similar manner as during the June 2007 sampling event (see Section 2.1.2).Samples were packaged and shipped under chain-of-custody procedures to MidWest Laboratory of Northbrook, Illinois for analysis of tritium (EPA Method 906.0).QA/QC procedures during the July 2007 monitoring event included one field duplicate sample (MW-32S, see Table 3). The duplicate sample was submitted for analysis; however, it was labelled with a unique name, such that the laboratory was not aware of the sample origin (i.e., DBD-01 as a duplicate of sample MW-32S).2.3 WELL INSTALLATION

2.3.1 Overview

The purpose of the well installation program was to characterize and confirm existing documentation of site subsurface geology and hydrogeology and to establish a reliable monitoring well network capable of evaluating the potential for inadvertent releases of radioactivity from the Power Block.The new monitoring well network includes an up-gradient well triplet to represent background conditions and 13 wells located between the Power Block and Lake Erie to evaluate groundwater quality down-gradient and cross-gradient of the Power Block.Prior to initiating the drilling activities, DBNPS conducted utility clearance activities at each of the proposed drilling locations. A site walkover was completed with Bowser-Morner, Inc. to verify access to each location with the drilling equipment. In addition, a kick-off meeting was conducted on 7 August 2007 to address site-specific logistics and health and safety issues.ERM/DADE MOELLER 8 FIRSTENERGY -DAVIS-BESSE 65992.2 16MAR08 ERM/ DADE MOELLER 8 FIRSTENERGY -DAVIS-BFSSE 65992.2 18 MAR 08

2.3.2 Advancement

of Soil Borings From 8 to 29 August 2007, sixteen soil borings were advanced at DBNPS by Bowser-Morner, Inc. using a truck mounted Sonicor K-50 drill rig.Boring depths ranged from 28 to 90 feet below ground surface. The borings were advanced using sonic drilling technology, which is a dual-case drilling system that employs simultaneous high-frequency vibration and low speed rotation, coupled with down-pressure to advance the drill bit. The drilling method advances a uniform borehole while providing continuous, representative and relatively undisturbed core samples. The dual casing system was used at all locations and was advanced in 10-foot increments. Each 10-foot core sample was collected within polyethylene sleeves allowing for visual logging and field screening. The sleeves were cut lengthwise to allow visual logging of grain size, degree of sorting, color and relative moisture content of the recovered materials. Field screening for low level gamma emitting radiation was performed using a Ludlum micro R meter scanned over the core sample. Field screening for total volatile organics was performed using a MiniRAE 2000 photoionization detector (PID).Following completion of each soil boring, the inner and outer drill rods were thoroughly steam cleaned to remove residual solid and liquids from the drilling equipment. Drill cuttings were collected and containerized in 55-gallon drums and labeled to identify the origin and type of material (i.e., boring identification, soil and/or water). DBNPS managed the investigation derived waste by discharging the water into the South Settling Basin, an APC that has historically contained tritium, and placing the soil south of the Power Block. Borehole logs were prepared and are included in Appendix A.2.3.3 Monitoring Well Construction Each soil boring was completed as a monitoring well by installing two-inch inside diameter polyvinyl chloride (PVC) screen (0.010-inch slot) and riser. After installation of the PVC well materials, the outer casing of the sonic drilling system was slowly removed from the soil boring. The annular space between the PVC and the inner wall of the drill rod was filled as the drill rods were removed. The annular space around the PVC was filled as follows: 0 Sand filter pack -coarse grained silica sand around the PVC screen.ERM/ DADE MOELLER 9 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 9 Bentonite seal -bentonite pellets above the silica sand.* Grout seal -bentonite/cement slurry to ground surface.Ten of the monitoring wells were capped with lockable expansion plugs and finished with flush mounted road boxes. The remaining six monitoring wells were capped either with a lockable expansion plug or a PVC slip cap and finished with a steel stick-up pipe secured in a concrete pad.2.3.4 Monitoring Well Development Following construction of the new wells, Bowser-Morner Inc. developed the wells to remove water and sediments introduced to the screen and riser during well construction. Well development was completed by removing groundwater using either a dedicated, disposable polyethylene bailer with nylon rope or a Whaler submersible pump. Non-dedicated equipment (pumps and tubing) was decontaminated between each well.Prior to development, the volume of water inside the well was calculated, with a goal of removing 10 well volumes. Lower Dolomite wells MW-101C, MW-102C, MW-103C, and MW-104C purged dry several times during the development activities, resulting in the removal of less than 10 well volumes from these wells. Strong hydrogen sulfide odors were noted from the development water pumped from these wells. The presence of sulfide is believed attributed to the dissolution of naturally occurring gypsum and anhydrite minerals within the Lower Dolomite. Regionally, the occurrence of these minerals within the Dolomite Bedrock is attributed to high concentrations of hydrogen sulfide in water wells (Water Resources of Ottawa County Fact Sheet, Graham et al., 1998).Groundwater from the development activities was containerized in either 55-gallon drums or 250-gallon totes and labeled to identify the origin of the water. Samples from the containers were collected and analyzed at DBNPS to support waste management. 2.4 SEPTEMBER/OCTOBER 2007 GROUNDWATER MONITORING ACTIVITIES Upon completion of the new monitoring wells, a Groundwater Field Sampling Plan (ERM, 20 September 2007) was prepared to outline procedures for groundwater sampling at the new monitoring wells, as well as select historic monitoring wells. The purpose of the FSP was to ERM/DADE MOELLER 10 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 document the sampling locations, methodologies, analytical techniques, and QA/QC measures for the collection of representative groundwater samples.Sampling locations identified in the September 2007 FSP represented all the new monitoring wells and select historic monitoring wells. The rationale for selecting the wells is included in Table 2. The list included wells screened in the Glaciolacustrine, Till, Upper and Lower Dolomite Bedrock.Groundwater samples were collected using low-flow methodologies. Sampling depths were specified for each well as the mid point of the saturated screened interval. QA/QC procedures were implemented in both the field and analytical program.The purpose of the September/October 2007 monitoring event was to evaluate if tritium and gamma emitting radionuclides associated with inadvertent releases from plant operations had migrated into groundwater at DBNPS. From 24 September to 10 October 2007, BETA Laboratory personnel conducted groundwater monitoring at 32 monitoring wells: " Historic monitoring wells: MW-12S, MW-12D, MW-15S, MW-15D, MW-20S, MW-20D, MW-23S, MW-30S, MW-30D, MW-31S, MW-31D, MW-33S, MW-33D, MW-35S, MW-35D, and MW-37S;and* New monitoring wells: MW-100A, MW-100B, MW-100C, MW-101A, MW-101B, MW-101C, MW-102A, MW-102B, MW-102C, MW-103A, MW-103B, MW-103C, MW-104A, MW-104B, MW-104C, and MW-105A.On 24 September 2007, prior to sampling, the depth to groundwater was measured in each well using an electric water level meter. Low-flow samples were collected using a peristaltic pump with disposable tubing or a non-dedicated bladder pump.Purging, measurement of field parameters and sample collection for laboratory analysis in September/October 2007 were performed in a similar manner as during the June 2007 sampling event (see Section 2.1.2).Wells MW-101C and MW-103C were purged dry during low-flow pumping. Field parameters at these wells were collected during the purging activities and the groundwater sample was collected after the groundwater level had recovered to within 90 percent of the original level.ERM/ DADE MOELLER 11 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 QA/QC procedures during the September/October 2007 monitoring event included field and laboratory methods to assess the overall analytical results. QA/QC procedures included collection of the following additional samples (Table 3):* Field Duplicate -duplicate samples were collected at four wells (MW-12D, MW20S, MW-31S, and MW-103B) to evaluate laboratory analytical precision. The duplicate samples were submitted for the same analysis as the actual samples with unique names such that the laboratory was not aware of the samples' origin. (i.e., DBD-01 as a duplicate of sample MW-12D, DBD-02 as a duplicate of sample MW-20S, DBD-03 as a duplicate of sample MW-31S, and DBD-04 as a duplicate of sample MW-103A).* Matrix Spike/Matrix Spike Duplicate -two additional samples were collected at MW-30S and MW-100A and spiked at the laboratory with a standard of 17,185 and 27,496 pCi/L of tritium and 65.6 and 98.4 pCi/L of cesium-137.

• Laboratory Duplicate

-outside of the FSP requirements, the laboratory collected and analyzed split samples to evaluate laboratory precision of tritium analysis. The laboratory duplicate samples (i.e., MW-33S duplicate and MW-102A duplicate) were collected by splitting samples from MW-33S and MW-102A, respectively.

• Equipment Blank -a rinseate sample was collected after decontaminating the bladder pump at MW-103C to evaluate the effectiveness of decontamination procedures and the potential for cross-contamination between wells introduced by the sampling equipment.

2.5 SURVEYING

Select historic wells (MW-14D, MW-18S/D, MW-19S/D, MW-21S/D, MW-30S/D, MW-38S/D and MW-39S/D) and all new monitoring wells were surveyed on 11 and 12 December 2007 by B.E.C. Associates, Inc., a professional survey company retained by ERM. Elevation data were collected relative to NAVD 1929 sea level vertical datum. Historic wells were selected for elevation surveying was based on observed physical alterations to the well casings during the initial inspection. Documented survey data in DBNPS files was used for the remainder of the historic wells.ERM/ DADE MOELLER 12 FIRSTENERCY -DAVIS-BESSE 65992.2 18 MAR 08 2.6 DATA USABILITY ASSESSMENT An assessment of the June, July/August 2007 and September/October 2007 analytical data was performed to determine the usability of the groundwater data for the intended purpose of the monitoring event. The usability of groundwater data was evaluated by initially conducting a review of the Low-Flow Groundwater Sampling Forms against methods outlined in the FSP in order to assess deviations from the original FSP.Secondly, the analytical results were evaluated in terms of data quality standards termed "PARCCs" parameters (i.e., precision, accuracy, representativeness, comparability and completeness of the data).Additional data review and verification included a statistical analysis of the radiological data reported by MidWest Laboratory to determine the range in the local background concentration of tritium in groundwater at Davis-Besse. The need for a statistical evaluation was based on the detection of low level tritium concentrations reported by the laboratory and follows industry guidance (EPRI, 2005).ERM/DADE MOELLER 13 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08

3.0 RESULTS

3.1 SITE GEOLOGY The surficial geology beneath the DBNPS property is characterized as Glaciolacustrine and Till units underlain by Dolomite Bedrock. Although not encountered in the new boreholes, a layer of fill is reportedly present within the area excavated during construction of the Power Block.Based on field observations during the recent drilling activities as well as information presented in historic reports, the relative thickness and elevation of geologic units encountered at DBNPS are summarized below.Summary of Geologic Units at DBNPS Unit Approximate Depth Approximate Elevation Interval(s) Below Ground Range (feet above mean sea Surface (feet below ground) level)Glaciolacustrine 0 -10 feet 574 feet -564 feet Till 10 feet -20 feet 564 feet -554 feet Dolomite Bedrock 20+ feet 554 feet and below The Glaciolacustrine unit is characterized as brown silt with some sand and clay. This formation consists of sediments of a complex, unconsolidated nature that were deposited within a temporary lake formed during the recession of glacial ice from Lake Erie. The underlying Till unit is defined as a brown to dark gray silty clay. The surfaces of the Glaciolacustrine and Till deposits slope towards Lake Erie.Beneath the Glaciolacustrine and Till units is the Dolomite Bedrock. This bedrock unit consists of argillaceous dolomite that has been subdivided into a Massive Dolomite and a Laminated Dolomite. The Massive Dolomite is approximately 10 feet in thickness, hard, finely grained, and present approximately 10 feet below the ceiling of the Dolomite. The Laminated Dolomite is encountered above and below the Massive Dolomite and includes thin layers of interbedded dolomite, gypsum, anhydrite and shale. Bedrock joints oriented to the northeast (N45°E) and northwest (N50°W) were reportedly observed in the bedrock during ERM/DADE MOELLER 14 FIRSTENERGY -DAVIS-BESSE 65992.2 18MAR08 ERM/ DADE MOELLER 14 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 excavation of the Power Block. Beds within the Dolomite Bedrock have a natural dip of less than one degree to the south.3.2 HISTORIC WELL INVENTORY Table 1 and Figure 2 present a summary of historic monitoring wells evaluated during the well inventory. The monitoring wells were originally installed during construction of DBNPS to assess the effectiveness of a dewatering system that operated during plant construction. The historic wells were installed as couplets with screened in the Upper and Lower Dolomite and are located north, east, south and west of the Power Block. The historic wells consist of 3-inch diameter, 20-foot screen wells installed at depths varying between 29.37 and 49.65 feet (Upper Dolomite wells) and from 72 and 86 feet (Lower Dolomite wells).Based on historic documentation, the Upper and Lower Dolomite wells are separated by the Massive Dolomite unit.The following monitoring wells were not located during the well inventory and therefore were not evaluated further: MW-8S, MW-8D, MW-9S, MW-9D, MW-10S, MW-10D, MW-13S, MW-13D, MW-16S, MW-.16D, MW-17S, MW-17D, MW-24S, MW-24D, MW-25S, MW-25D, MW-27S, MW-27D, MW-28S, MW-28D, MW-29S, MW-29D, MW-36S, and MW-36D.3.3 NEW MONITORING WELLS A total of 16 monitoring wells were installed at five locations at DBNPS to assess existing data gaps and to increase the reliability of the historic well network (Figure 2). The new wells were located to characterize groundwater quality up-gradient and down-gradient of the Power Block.Five well triplets and a single well were installed. Each triplet is characterized by three individual monitoring wells that are screened across a specific target depth interval at each location: Base of Till, Upper Dolomite, and Lower Dolomite.The following table summarizes the newly installed monitoring wells and their location relative to the Power Block.ERM/DADE MOELLER 15 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 Summary of New DBNPS Monitoring Wells S Well ID Location/Hydraulic Position Relative Target Depth of Well Screen the to Power Block MW-100A MW-100B MW-100C MW-101A MW-101B West/ Up-gradient Base of Till.Upper Dolomite Lower Dolomite Base of Till Uper Dolonmitte Lower Dolomite East/ Down-gradient MW-101C MW-102A MW-102B MW-102C Base of Till Northeast/Down and cross-gradient Upper Dolomite Lower Dolomite MW-103A Base of Till MW-103B Northeast/ Down and cross-gradient MW-103C Upper Dolomite Lower Dolomite Base of Till-..---.....

Borehole logs and well construction diagrams for the new monitoring wells are included in Appendix A.GROUNDWATER FLOW Table 4 presents a summary of depth to groundwater measurements and calculated groundwater elevations during the well inventory and groundwater monitoring events. During each monitoring event, the elevation of groundwater was generally higher than the elevation of surface water in Lake Erie, indicating regional groundwater flow is from west to east at DBNPS.U 3.4 ERM/DADE MOELLER 16 DRSTENERGY -DAVIS-BESSE 65992.2 18MAR08 ERM/DADE MOELLER 16 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 Surface Water 1 and Groundwater Elevations Date Range in Surface Water Range in Groundwater Elevation Lake Erie (feet above Elevations in the Site sea level) Monitoring Wells 9 May 2007 571.80 -572.48 570-54 -575.91 11 June 2007 571.72 -571.91 570.52 -574.79 31 July 2007 571.10 -571.42 569.97 -573.90 24 September 2007 570.87 -571.17 517.62 -573.96 1 National Oceanic and Atmospheric Administration station 9063079 in Marblehead, OH As indicated in the above table, groundwater elevations below the elevation of surface water in Lake Erie were observed during each monitoring event. The occurrence of low groundwater elevations likely reflects site-specific conditions at DBNPS that complicate the ability to evaluate groundwater elevations and precise flow directions. Complicating factors include the presence of a grout curtain, the flow of groundwater within discrete fractures in bedrock, the large area of excavated bedrock beneath the Power Block and the high degree of mineralized groundwater and associated low yield observed in the new Lower Dolomite wells. An additional source of uncertainty is the usability of historic elevation survey data that were used to calculate groundwater elevations from the historic wells.Low groundwater elevations were measured at Lower Dolomite wells MW-101C, MW-102C, MW-103C and MW-104C, located east and northeast of the Power Block. As previously indicted, each of these wells demonstrated a low yield during the well development activities and contained high levels of hydrogen sulfide gas. The use of expansion plugs may be inadvertently trapping sulfide gas inside the wells and around the well screen, thereby limiting the screens ability to communicate with the Lower Dolomite. Future modifications to the expansion plugs to allow venting of the sulfide gas will be evaluated in effort to obtain more accurate groundwater elevation data from these wells.Figures 3, 4, and 5 present groundwater elevations for the Till, Upper Dolomite and Lower Dolomite, respectively, during the September 2007 monitoring event. Groundwater elevation contours were not developed due to the complicating site-specific factors and their potential to impact groundwater flow. However, groundwater flow directions at DBNPS ERM/DADE MOELLER 17 FIRSTENERGY-DAVIS-BESSE 65992.2 18 MAR 08 within the Till, Upper Dolomite and Lower Dolomite can be evaluated by comparing groundwater elevations in new across the site.Groundwater elevations in Till wells MW-100A, MW-101A, MW-102A, MW-103A and MW-104A are presented in Figure 3. The highest groundwater elevation in the Till was 573.91 feet measured up-gradient (i.e., west) of the Power Block at MW-100A. The lowest groundwater elevation was measured at MW-105A at 568.73 feet, which is below the elevation of surface water in Lake Erie. Based on the distribution of groundwater elevations, groundwater flow in the Till is from west to east across the site. Approximate flow directions in the Till (Figure 3) are orientated perpendicular to the shoreline of Lake Erie.Groundwater elevations in the Upper Dolomite are presented in Figure 4.The highest groundwater elevation in the Upper Dolomite was 573.96 feet measured up-gradient (i.e. west) of the Power Block at MW-100B. The lowest groundwater elevations in the Upper Dolomite were located northeast of the Power Block (MW-31S at 571.08 feet) and southeast of the Power Block (MW-12S at 570.98 feet). Based on the distribution of groundwater elevations, groundwater flow in the Upper Dolomite is from west to east across the site. Approximate flow directions in the Upper Dolomite (Figure 4) are orientated perpendicular to the shoreline of Lake Erie.Groundwater elevations in the Lower Dolomite are presented in Figure 5.The highest groundwater elevation in the Lower Dolomite was 573.56 feet measured up-gradient (i.e. west) of the Power Block at MW-100C. In general, lower groundwater elevations in the Lower Dolomite were located east of the Power Block. Based on the distribution of groundwater elevations, groundwater flow in the Lower Dolomite is from west to east across the site. Approximate flow directions in the Lower Till (Figure 5)are orientated perpendicular to the shoreline of Lake Erie.Groundwater elevations decreased in site wells from May to July, and again from July to September. This trend mimics the decline in elevation of surface water in Lake Erie over the same period, signifying that the marshes and/or Lake Erie are the discharge boundary for groundwater. Comparison of groundwater elevations between the Till and Upper Dolomite allows for assessment of vertical groundwater flow gradients. Using data from the new monitoring wells, an upward flow gradient is observed from the Upper Dolomite to the Till unit. As previously indicated, the elevation of groundwater in all three units is higher than the elevation of surface water in Lake Erie (except where anomalies are noted)ERM/DADE MOELLER is FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 further indicating that groundwater within all three units is ultimately discharging to the marshes and/or Lake Erie.3.5 GROUNDWATER QUALITY 3.5.1 Groundwater Field Parameters Groundwater field parameters collected at the time of groundwater sampling in June 2007, July/August 2007 and September/October 2007 are summarized in Table 5. A summary of the field parameter data is presented below." Temperature -Groundwater temperatures ranged from 13.6 to 25.6 degrees Celsius (°C). In general the highest temperatures were measured in wells located directly down-gradient of the Power Block. The highest temperatures were observed at MW-34S/D (25.6, 24.1oC), MW-33S/D (25.5, 25.20C), and MW-31S/D (24.5, 23.1oC). Groundwater temperatures in other areas were below 20oC.* Specific conductivity -Groundwater specific conductivity ranged from 113 uS/cm to values greater than 10,000 uS/cm. The highest specific conductance values (i.e., greater than 50,000 uS/cm) were measured in Lower Dolomite wells MW-101C, MW-102C, MW-103C and MW-104C. As indicated earlier, these wells were noted with high hydrogen sulfide gas, low yield and low groundwater elevations. The high specific conductance measured at these wells relative to other wells further suggests that the well screens at these four locations have limited connection to the Lower Dolomite.* Dissolved oxygen (DO) -Several DO measurements were rejected from the monitoring events due to probe interference with hydrogen sulfide. Accepted DO levels in groundwater ranged from 0.04 to 4.24 milligrams per liter (mg/L). The reported odors of sulfide are indicators of anaerobic and depleted oxygen conditions." pH -The pH of groundwater ranged from 6.0 to 8.8 standard pH units. The limited variations in pH values are most likely due to the influence of the Dolomite Bedrock. Dolomite is a carbonate rock and is anticipated to buffer pH changes in groundwater.

• Oxidation Reduction Potential

-ORP values ranged from -368 to 87 millivolts (mV). ORP values were generally below 50 mV in all of ERM/ DADE MOELLER 19 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 the wells, indicating that site groundwater is subject to reducing conditions (anaerobic). A trend shows that values decrease with depths.Turbidity -With the exception of wells MW-101C (798), MW-102C (10) and MW-104C (38), the turbidity of groundwater was low (i.e., less than 10 nephelometric turbidity units). High turbidity values at MW-101C, MW-102C and MW-104C are consistent with the high specific conductance at these wells and the well screens limited ability to communicate with the Lower Dolomite.3.5.2 Analytical Results Data Summary Groundwater analytical results from the June, July/ August 2007, and the September/October 2007 groundwater monitoring event are summarized in Table 6. Figure 5 presents a summary of the June, July/August 2007 tritium results, while Figure 6 presents a summary of the September/October 2007 tritium results. Appendix C and Appendix D include an assessment of the usability of the groundwater analytical data for the June, July/August, and September/October 2007 monitoring events, respectively. As indicated in Appendices B and C, the analytical data presented in Table 6 meet the data quality objectives in the FSPs and are usable for the intended purpose of the groundwater monitoring program. Appendix D also includes a statistical evaluation to determine the range in local background concentrations. Laboratory analytical reports are included in Appendix E.Local Background Conditions As presented in Appendix C, reported tritium concentrations between 178 pCi/L and 348 pCi/L represent statistically insignificant activity at the.95% confidence level. Therefore, values at or below 348 pCi/L were considered to be representative of local background conditions. Factors influencing local background conditions may include the historic atmospheric bomb testing program, cosmic ray interactions in the earth's atmosphere and localized washout from continuous and batch gaseous releases from DBNPS.June and July/August 2007 Results Analytical results of tritium samples collected in June 2007 ranged from less than the minimum detectable concentration (MDC, i.e., <330 pCi/L)ERM/DADE MOELLER 20 FIRSTENERGY -DAVIS-BESSE 65992.2 18MAR08 ERM/DADE MOELLER 20 FI RSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 to 5,838 pCi/L (MW-32S). Tritium detections during the July/August 2007 confirmation round ranged from 108 pCi/L (MW-31D) to 7,535 pCi/L (MW-32S). No gamma emitting radionuclides were detected above their respective MDCs.Tritium concentrations detected above the 348 pCi/L background value were located primarily in monitoring wells east of the Power Block. In the Upper Dolomite, the highest concentrations were present east of the Power Block, including MW-31S, MW-32S, MW-33S, and MW-34S.Elevated detections above local background were also measured in the Upper Dolomite north of the Power Block at well MW-30S (1,307 pCi/L)and well MW-37S (2,961 pCi/L).In the Lower Dolomite unit, the highest detections were located east/southeast of the Power Block, including wells MW-33D, MW-34D and MW-12D.September/October 2007 Results In September/October 2007, tritium concentrations ranged from less than the MDC (149 pCi/L) to 3,149 pCi/L (MW-31S). The concentrations of tritium in new wells MW-100A, MW-100B and MW-100C, which are located hydraulically up-gradient of the Power Block, were <193 pCi/l,<193 pCi/L and <149 pCi/l, respectively. No gamma emitting radionuclides were detected above their respective MDCs in any of the groundwater samples collected during the September/October 2007 sampling event.Concentrations above local background in the Till were detected down-gradient (i.e., northeast) of the Power Block, including MW-102A (387 pCi/L, Till Unit), MW-103A (495 pCi/L, Till Unit), and MW-105A (1,832 pCi/L, Glaciolacutrine/Till Unit).Tritium concentrations above local background in the Upper Dolomite were detected north of the Power Block in wells MW-30S and MW-37S, consistent with the June and July/August 2007 events. The highest concentrations in the Upper Dolomite were detected east/northeast of the Power Block including wells MW-31S and MW-33S. Elevated tritium in the Upper Dolomite was not detected in new monitoring wells MW-102B, MW-103B and MW-104B, located to the northeast of MW-31S/D.For the Lower Dolomite, the highest concentrations above local background were detected in wells MW-12D, MW-15D and MW-33D, located east/ southeast of the Power Block. Tritium was not detected ERM/DADE MO0ELLER 21 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 above local background in any of the new monitoring wells east of the Power Block within the Lower Dolomite (i.e., MW-101C, MW-102C, MW-103C and MW-104C). As previously indicated, groundwater at these wells may not be connected to the Lower Dolomite due to the presence of hydrogen sulfide gas.Comparison to Drinking Water Standards Tritium concentrations in groundwater during the June, July and August and September/October 2007 monitoring events were below the Environmental Protection Agency's drinking water standard of 20,000 pCi/L.3.5.3 Tritium Source Assessment As indicated in the January 2007 Groundwater Flow Characteristics Report (ERM, 16 January 2007), potential sources of the elevated tritium detected in groundwater may be associated with plant operations in the following areas and/or documented historic liquid releases (Figure 2):* Power Block -consisting of potential sources within the Reactor Containment, Auxiliary Building, Circulating Water Pump House, Turbine Building and Borated Water Storage Tank.* Spent Fuel Pool, Fuel Transfer Canal and Cask Pit -as outlined in the investigation summary of DBNPS Condition Report # 04-01719, several instances of leakage from the Spent Fuel Pool have been recorded. Since the elevation of the pool is from 563.3 to 601.5 feet above sea level, leakage from the Spent Fuel Pool and/or interconnected Fuel Transfer Canal and Cask Pit could potentially release tritiated water to the structural backfill surrounding the Power Block or to the Upper Dolomite.* Condensate Demineralizer Tank Discharge Line -as documented in the DBNPS 10 CFR 50.7 5(g) file, in May 1990 a break in the discharge line exiting the Condensate Demineralizer Polisher Tank was discovered east of the Power Block. Contaminated resin was released to soil at the connection between the Condensate Demineralizer Backwash Receiver Tank discharge line and a 10-inch pipe that conveyed the resin to South Settling Pond.* Collection Box -as documented in the DBNPS 10 CFR 50.7 5 (g) file, approximately 12,000 gallons of water was spilled to the ground ERM/DADE MOELLER 22 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 adjacent to the Collection Box in 1997. It was estimated that the concentration of tritium in the release water was 6,850 pCi/L.Hydrogen Addition System -as documented in the DBNPS 10 CFR 50.7 5(g) file, primary grade water was spilled onto the ground near the Borated Water Storage Tank while draining the Hydrogen Addition System in 1991.ERM/DADE MOELLER 23 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08

4.0 UPDATED

CONCEPTUAL SITE MODEL The spatial distribution of tritium in groundwater and groundwater flow patterns can be used to update the CSM regarding the potential inadvertent release, fate and transport of tritium at DBNPS. The CSM was originally presented in the Groundwater Flow Characteristics Report -Davis-Besse Nuclear Power Station, Oak Harbor, Ohio.Groundwater flow within the Till, Upper Dolomite and Lower Dolomite units at DBNPS is from west to east toward Lake Erie. Higher groundwater elevations within these units compared to the elevation of surface water in Lake Erie indicates that groundwater discharges to the marshes and/or Lake Erie.Potential inadvertent releases from within the Power Block, including the Spent Fuel Pool, would migrate vertically down through the unsaturated zone to the water table. Upon encountering the water table, tritium would be transported laterally through the Till in an easterly direction towards Lake Erie. Potential releases below the water table could release tritium directly to the Upper or Lower Dolomite unit.Reported mapping of jointing and fractures on the upper surface of the Dolomite Bedrock indicated orientations southwest to northeast and a secondary orientation from southeast to northwest. These fractures represent the direction of potential preferential migration pathways within the Dolomite Bedrock. Elevated detections in Upper Dolomite wells MW-31S and MW-32S are located on fracture projections that trace back (i.e., southwest) to the Power Block.Tritium in groundwater will ultimately migrate into Lake Erie, where the concentrations will be diluted due to the volume of groundwater discharge versus the volume of water in the lake. This is supported by DBNPS Radiological Effluent Monitoring Program (REMP) data that indicates tritium levels typically below 330 pCi/L in surface water samples from Lake Erie.ERM/ DADE MOELLER 24 FIRSTENERGY -DAVIS-BESSE 65992.2 18MAR08 ERM/ DADE MOELLER 24 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 5.0 KEY FINDINGS The key findings from the groundwater investigation include the following: Geology The surficial geology beneath the DBNPS consists of Glaciolacustrine and Till units. The Glaciolacustrine unit is characterized as cohesive, brown silt with some sand and clay. The Till is characterized as brown to dark-gray, silty clay." Beneath the Till is Dolomite Bedrock, subdivided into a Laminated Dolomite and a Massive Dolomite. The Laminated Dolomite, which is encountered above and below the Massive Dolomite, contains thin layers of interbedded dolomite, gypsum, anhydrite and shale. The Massive Dolomite is approximately 10 feet thick, hard, finely grained, and located approximately 10 feet below the top of the Dolomite.Historic Well Inventory" A total of 54 wells (27 couplets) were located and inspected during the well inventory and 24 wells (12 couplets) could not be found.Each well couplet consists of a shallow and deep well within the Dolomite Bedrock. The shallow bedrock well is screened within the Upper Dolomite and the deeper bedrock well is screened in the Lower Dolomite. The Massive Dolomite unit separates wells screened within the Upper and Lower Dolomite.* The historic wells, by themselves, were not sufficient to create an effective groundwater monitoring program at DBNPS because they did not provide adequate lateral and vertical coverage. In addition, due to the age of the wells, their construction quality and subsurface conditions are not known.Groundwater Flow The ability to develop groundwater elevation contours and flow patterns is complicated by several factors, including the presence of a grout curtain, the flow of groundwater within discrete fractures in bedrock, the large area of excavated bedrock beneath the Power ERM/DADE MOELLER 25 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 Block and the high degree of mineralized groundwater and associated low yield observed in the new Lower Dolomite wells.An additional uncertainty is the usability of historic elevation survey data that were used to calculate groundwater elevations from the historic wells.0 Based on the distribution of groundwater elevations, groundwater flow in the Till, Upper Dolomite and Lower Dolomite units is from west to east across the site.* The ultimate discharge point for groundwater in the Till, Upper Dolomite and Lower Dolomite is the marshes and/or Lake Erie east of the Power Block.Groundwater Quality* Strong hydrogen sulfide odors were noted in site groundwater, particularly new Lower Dolomite wells MW-101C, MW-102C, MW-103C and MW-104C located east of the Power Block. The hydrogen sulfide is believed to be naturally occurring and caused by the weathering of gypsum and anhydrite minerals. Groundwater field parameters at these wells are characterized by high specific conductance, low ORP and high turbidity water.* High hydrogen sulfide gas levels at wells MW-101C, MW-102C, MW-103C and MW-104C may be inadvertently trapped due to the use of expansion plugs at these wells. The sulfide gas may limit the ability for the well screen to communicate with the Lower Dolomite. Future modifications to the expansion plugs to allow venting of the sulfide gas will be evaluated in effort to obtain more accurate groundwater elevation data from these wells." Reported concentrations of tritium in groundwater between 178 pCi/L and 348 pCi/L represent statistically insignificant activity at the 95% confidence level and are considered representative of local background conditions. Factors influencing local background condition may include the historic atmospheric bomb testing program, cosmic ray interactions in the earth's atmosphere and localized washout from continuous and batch gaseous releases from DPNBS. Reported values above 348 pCi/L represent concentrations that are statistically greater than local background conditions. ERM/DADE MO0ELLER 26 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 " Tritium concentrations above the 348 pCi/L background value were located primarily in monitoring wells east of the Power Block." Tritium concentrations in the wells screened in the Till ranged from less than the minimum detectable concentration (MDC; <193 pCi/L) to 1,832 pCi/L. The highest concentrations were detected down-gradient (northeast) of the Power Block, including MW-102A (387 pCi/L), MW-103A (495 pCi/L), and MW-105A (1,832 pCi/L)." Tritium concentrations in the wells screened in the Upper Dolomite ranged from less than the MDC (<193 pCi/L) to 7,535 pCi/L. The highest concentrations were detected down-gradient (east) of the Power Block, including MW-31S, MW-32S, MW-33S, MW-34S, MW-37S and MW-30S. Two detections above local background conditions were detected at well MW-30S (1,307 pCi/L) and well MW-37S (2,961 pCi/L), located north of the Power Block.* Tritium concentrations in the wells screened in the Lower Dolomite ranged from less than the MDC (<193 pCi/L) to 3,271 pCi/L. The highest detections were located east/southeast of the Power Block, including wells MW-33D, MW-34D and MW-12D." No gamma emitting radionuclides were detected above MDC in any of the groundwater samples collected during the June, July/August 2007 or the September/October 2007 monitoring events.* Tritium concentrations in groundwater during the June, July and August and September/October 2007 monitoring events were below the Environmental Protection Agency's drinking water standard of 20,000 pCi/L.Updated CSM" Groundwater flow within the Till, Upper Dolomite and Lower Dolomite units at DBNPS is generally from west to east toward Lake Erie with groundwater discharge to the marshes and/or Lake Erie.* Potential inadvertent releases from within the Power Block, including the Spent Fuel Pool, would migrate vertically down through the unsaturated zone to the water table. Potential releases from structures below ground could release tritium directly to the Upper or Lower Dolomite unit.ERM/DADE MOELLER 27 FIRSTENERGY -DAVIS-BESSE 65992.2 18 MAR 08 " Elevated detections in Upper Dolomite wells MW-31S and MW-32S are located on reported southwest to northeast fractures that project back to the Power Block.* Tritium in groundwater will ultimately migrate into Lake Erie, where the concentrations will be diluted due to the volume of groundwater discharge versus the volume of water in the lake." Historic monitoring of Lake Erie by DBNPS indicates that there have been few detections of tritium above local background conditions, none of which are believed to be attributed to groundwater releases.Based upon the above findings, FirstEnergy should further evaluate the hydrogeology and influence of plant features on site groundwater flow.In addition, tritium detections above local background conditions should be evaluated to establish a reliable monitoring well network for long-term monitoring.

1.0 INTRODUCTION

This section presents a quality assurance and quality control (QA/QC)review of the Davis-Besse June and July/August 2007 well groundwater sampling events. This evaluation was conducted to assess and enhance the reliability and validity of the groundwater analytical data. The verification process was conducted to identify the most common sampling and analytical problems that could affect the quality of the results. In general, the results met the data quality objectives.

2.0 QUALITY

ASSURANCE Quality assurance involves planned and systematic actions necessary to provide confidence in the analytical results. The goal of the program is to have a program that is operating within acceptable criteria; thereby enhancing the representativeness and comparability of the results.Qualitative measures include items related to the field as well as the laboratory activities.

2.1 SAMPLING

PROGRAM The procedures used to collect the groundwater samples were detailed in a FSP (ERM, 8 June 2007). Specifications, such as well locations, well construction, sampling intervals, sampling and analysis techniques were items among others that were described to help collect a useful data set.A list of sampling locations and analytical program summary tables were provided for the July/August 2007 groundwater monitoring event.Groundwater samples were collected by personnel from BETA Laboratory. Field notes were reviewed to confirm that the procedures were executed properly. The following information reviews items that were included in the field sampling quality assurance program.Sampling documentation -The sample team maintained a field notebook (bound weatherproof logbooks) that was filled out at each location where a sample was collected. It contains the sample designation, collection time, description, and field instrument calibration log. The team also completed a Low-Flow Groundwater Sampling Form at each monitored location. The forms present information regarding location, weather, time, well construction, ERM/DADE MOELLER 1 FIRSTENERGY -DAVIS-BESSE 0065992.218 MARCH 08 sampling depths, sampling device, field parameters and sample containers. The completed Low-Flow Groundwater Sampling forms are included within Appendix B." Sample Identification -Well IDs were used to identify the groundwater samples. The same codes were used to complete the chain-of-custodies (COCs). Duplicate samples were recorded as blind samples. Actual duplicate sample IDs were recorded on each Low-Flow Groundwater Sampling Form. COC records are included within Appendix B." Decontamination -Dedicated high density polyethylene (HDPE)tubing was used at each location. Wells were sampled using a peristaltic pump (no decontamination required).

• Calibration and Preventive Maintenance of Field Instruments

-Sampling team personnel calibrated the geochemical parameters probe every day before starting the sampling. Calibration logs were maintained in the notebook. ORP readings did not stabilize during June sampling of well MW-20D. The ORP probe was cleaned after this sampling and the meter accuracy was successfully checked utilizing calibration solution. Dissolved Oxygen reading could not be taken for about 57% of the wells sampled in July/ August 2007 due to probe interference with hydrogen sulfide.* Sampling locations -All locations were sampled as planned in the FSP." Gauging -A synoptic water level gauging round, including all of the monitoring wells selected for the evaluation of tritium and gamma emitting radionuclides, was performed on 11 June 2007 prior to sampling.* Sampling Depths -Sampling depths were reported on the individual Low-Flow Groundwater Sampling Forms. Sampling depths were consistent with sampling depths recommended in the Field Sampling Plan." Field Duplicates -All duplicate samples were collected in accordance with the FSP.ERM/DADE MOELLER 2 FIRSTENERGY -DAVIS-BESSE 0065992.218 MARCH 08

2.2 ANALYTICAL

PROGRAM Groundwater samples were analyzed by MidWest Laboratory for analysis of tritium by EPA Method 906.0 and gamma emitting radionuclides by EPA Method 901.1 as specified within the FSP. MidWest Laboratory currently performs radiological environmental monitoring for over 20 nuclear power plants in 11 states. In addition, the laboratory is certified to perform analysis of drinking water for radionuclides in Illinois, Indiana, Wisconsin, and Kentucky. Midwest Laboratory maintains a Quality Assurance / Quality Control Program based on 10 CFR Part 50, Appendix B and Reg. Guide 4.15.3.0 QUALITY CONTROL The analytical data were assessed in terms of precision, accuracy, representativeness, comparability and completeness (PARCCs) to evaluate the usability of the results generated. Quality control items were evaluated through laboratory checks (e.g., matrix spikes, duplicate samples), and sampling method reviews (equipment blanks, trip blanks).In addition, MidWest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of their quality control program in December 1971. Results of the interlaboratory program are presented at the end of this appendix.The following information provides background on the types of QC samples that were used to assess if the data quality objectives of the sampling program were met.Equipment Blanks -Equipment blanks are samples collected to evaluate the potential cross-contamination of samples due to the sampling equipment. They are collected by pouring deionized water over the sampling equipment which comes in contact with the groundwater sample. During the June and July/August 2007 sampling event, all monitoring wells were sampled with dedicated equipment. Therefore, no equipment blanks were collected. Field Duplicate Samples -Field duplicate samples are analyzed to check the accuracy and reproducibility of the laboratory analytical techniques. A field duplicate sample is taken from the same monitoring well, one immediately after the other using the same sampling device. Field duplicates are typically collected at locations where concentrations of COCs are expected to be present. As recommended in the field sampling plan, two duplicate samples were collected during the June 2007 sampling event (sampling ERM/DADE MOELLER 3 FIRSTENERGY -DAVIS-BESSE 0065992.218 MARCH 08 locations MW-12S and MW-20S), and one during the July/August sampling event (sampling location MW-32S).Laboratory (Split) Duplicate Samples -A laboratory duplicate sample is created when the laboratory splits a normal field sample.It is conducted to evaluate the precision of the laboratory. The laboratory conducted the analysis of one laboratory duplicate sample for the July/August sampling event (duplicate of field duplicate sample from location MW-32S)." Matrix Spike and Matrix Spike Duplicate samples -Matrix spike samples and matrix spike duplicate samples are normal field samples to which a known quantity of a chemical constituent is added in the laboratory. Spike samples are used to evaluate the precision of the laboratory and the effects of matrix interference on the analysis. MS/MSDs are typically collected in areas where concentrations of COCs are expected to be low. Spike samples were collected at MW-26D by collecting two additional samples as identified in Table 3. Samples were spiked by the laboratory with a tritium standard of 5,639 pCi/L and analyzed as actual samples.Assessment of data quality based on compliance with PARCCs criteria is presented below.* Precision -United States Environmental Protection Agency (EPA)guidance suggests that the Relative Percent Difference (RPD) of field duplicates should be less than 30 percent in water samples.The RPD is calculated as: RPD = I Sample -Duplicate I (Sample + Duplicate) / 2 Calculated RPD values for the tritium results were within guidelines, as presented in the following table.Field Duplicate RPD Calculations Sample Duplicate Sample Duplicate RPD ID ID Result Result MW-12S DBD-01 657 764 15 %MW-20S DBD-02 255 279 9 %MW-32S DBD-01 7,535 7,185 5 %FIRSTENERGY -DAVIS-BESSE 0065992.218 MARCH 08 ERM/DADE MOELLER 4 " Accuracy -Matrix spike/matrix spike duplicate (MS/MSD), and laboratory duplicate sample are documented in the attached laboratory reports. These indicators are used to assess if the matrix may be biasing the reported results high (generally based on greater than 130 percent recovery) or low (generally based on less than 70 percent recovery). RPDs are generally expected to be less than 30 percent between MS and MSD results.As shown in the following table, all RPDs for tritium and cesium were within acceptable ranges.Matrix Spike/Matrix Spike Duplicate RPD Calculations Sample Spike + Sample ID Compound Duplicate ID Initial Sample Result RPD Activities MW-26D Tritium MS01-MW-26D 5,639 5,000 12%MW-26D Tritium MSDO1-MW-26D 5,639 5,055 11%MW-26D Cs-134 MS01-MW-26D 59.3 62.9 6%MW-26D Cs-134 MSD01-MW-26D 59.3 59.1 0.3%MW-26D Cs-137 MS01-MW-26D 66.3 64.2 3%MW-26D Cs-137 MSDO1-MW-26D 66.3 70.0 5%No Cesium was detected in the actual samples. Values indicate actual spike activity." Representativeness and Comparability -The representativeness and comparability of analytical data was qualitatively evaluated by comparing samples from the same locations for the June 2007 and the July/August 2007 monitoring events.Groundwater Tritium Results Comparison -1st & 2n5d Sampling rounds Monitoring June 2007 lulv/August 2007 RPD Well MW-12S MW-30S MW-32S MW-32D MW-33S MW-33D H-3 Activity 764 1,307 5,838 466 2,287 2,965 H-3 Activity 860 1,149 7,535 507 2,702 3,271 12%13 %25 %8%17 %9%NA: Not Applicable Consistency between the monitoring events indicates that the sample results are representative of the site conditions. ERM/DADE MOELLER 5 FIRSTENERGY -DAVIS-BESSE 0065992.218 MARCH 08 " Completeness -Based on review of sampling and laboratory check-in procedures, as well as field and laboratory QA/QC results, the data is considered to be complete and useable.* Sensitivity -The MDCs were consistent with data quality objectives for the gamma emitting radionuclides as they ranged between 1.4 and 14.7 pCi/L. The MDCs were consistent with data quality objectives (at least 200 pCi/L) for tritium with the exception of detection limits of 330 pCi/L at 4 locations during the June 2007 sampling event (MW-1S, MW-1D, and MW-26D). The 200pCi/L value corresponds to an environmental level that would allow evaluating an eventual release of tritium to the environment.

4.0 CONCLUSION

Based on the review of the QA/QC information summarized above, the data meet the data quality objectives defined in the FSP and are usable for the intended purposes of supporting the final selection of locations for new monitoring wells at the site.ERM/DADE MOELLER 6 FIRSTENERGY -DAVIS-BESSE 0065992.2 18 MARCH 08 Site Name: n 0 Low-Flow Groundwater Sampling Form Wpflfl IT): Z Well ID, / -4Z'Date: to,/la 97 5amrilinePersclmiel: "",-, .-A~~ !f/,ttA Aiil~Weather Condition: S &- ,z-. .A-/,; Y" .. _- 4r rime: &~~~~C'OT File Name: Iotal Depth (I.D.): ...

Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported. Appendix A is updated four times a year;, the complete Appendix is included in March, June, September and December monthly progress reports only.October, 2006 through September, 2007 Appendix A Interlaboratory Comparison Procgram Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.Results in Table A-1 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.The results in Table A-2 list results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.-Table -A-3-lists-results-of-the analyses-on-in-house-"spiked"-samples-forth e-pa st-telve-rnO-th-s.-All-pples are prepared using NIST traceable sources. Data for previous years available upon request.Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years available upon request.Table A-5 list results of the in-house "duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.Results in Table A-7 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).Attachment A lists acceptance criteria for "spiked" samples.Out-of-limit results are explained directly below the result.Al Attachment A W ACCEPTANCE CRITERIA FOR "SPIKED" SAMPLES LABORATORY PRECISION: ONE STANDARD DEVIATION VALUES FOR VARIOUS ANALYSESa One standard deviation Analysis Level for single determination Gamma Emitters 5 to 100 pCi/liter or kg 5.0 pCi/liter> 100 pCi/liter or kg 5% of known value Strontium-89b 5 to 50 pCi/liter or kg 5.0 pCi/liter> 50 pCi/liter or kg 10% of known value Strontium-90b 2 to 30 pCi/liter or kg 5.0 pCi/liter> 30 pCi/liter or kg 10% of known value Potassium-40 > 0.1 g/liter or kg 5% of known value Gross alpha < 20 pCi/liter 5.0 pCi/liter> 20 pCi/liter 25% of known value Gross beta < 100 pCi/liter 5.0 pCi/liter 5%/-otkiwrlue Tritium < 4,000 pCi/liter 1 la = (pCi/liter) =169.85 x (known)0°0 9 3 3> 4,000 pCi/liter 10% of known value Radium-226,-228 ? 0.1 pCi/liter 15% of known value Plutonium > 0.1 pCi/liter, gram, or sample 10% of known value Iodine-131, -< 55 pCi/liter 6.0 pCi/liter Iodine-1 2 9 b > 55 pCi/liter 10% of known value Uranium-238, s 35 pCi/liter 6.0 pCi/liter Nickel-63b > 35 pCi/liter 15% of known value TechnetiUM~99b Iron-55 b 50 to 100 pCi/liter> 100 pCi/liter 10 pCi/liter 10% of known value 20% of known value Othersb a From EPA publication, "Environmental Radioactivity Laboratory Intercomparison Studies Program, Fiscal Year, 1981-1982, EPA-600/4-81-004. b Laboratory limit.A2 TABLE A-1.

Since tritium was the only radiological compound detected in water samples above the MDC, the analysis is only performed for tritium.Low level concentrations reported by the laboratory may reflect 1.)uncertainty in the sample and laboratory analysis; 2.) tritium from historic atmospheric bomb testing; 3.) tritium from cosmic ray interactions in the earth's atmosphere; or 4.) localized tritium washout from continuous and batch gaseous releases. In order to assess these local background condition levels, a statistical approach was used following industry guidance (EPRI, 2005) to evaluate the significance of the low level detections. Local background concentrations can also be defined by comparing reported tritium values from wells upstream of potential radiological source(s) of release. For example, wells MW-100 is located hydraulically up-gradient of potential source(s) of liquid tritium released from the Power Block. The reported concentrations of tritium were: <193, <193 and<149 for MW-100-A, -B and -C, respectively. The mean value is <178 pCi/L. This low level concentration limit provides a reference at which to evaluate reported results from samples collected down-gradient and cross-gradient of the Power Block. It is noted that MW-100A, -B and -C were sampled once; therefore, the background reference may change if more up-gradient wells were available. Additional evaluation of background can be performed by evaluating the reported concentrations in groundwater against concentrations in surface water from Lake Erie.A statistical approach was also used to define local background conditions. The results reported by Midwest Laboratory were compared against 2-sigma (o) total propagated uncertainty (TPU) of the analysis, with a 95% confidence level. The 2-o TPU value combines counting uncertainty and any other factors that contribute to the overall uncertainty including uncertainties in the sample mass, chemical yield and determination of calibration factors.ERM/DADE MOELLER 1 FIRSTENERGY -DAVIS-BESSE 0065992.2 18 MARCH 08 The 2-a TPU was estimated by calculating a raw standard deviation using the field and laboratory duplicate data collected during both the June 2007 and September/October 2007 event (Table 7). Both sets of data were used to provide a sufficient number of comparisons (i.e., population statistics) that could not be achieved if only using the September /October 2007 data. The field duplicates and laboratory duplicates from both events were used to measure the total uncertainty and evaluate the quality of the TPU estimate.The raw 2-o standard deviation was calculated at 87.3 pCi/L. The raw 2-o standard deviation includes the effects of stochastic variations, volume measurements, calibration errors, and chemical factors. A Student's t correction factor was calculated (1.9432) because the sample size is less than 30 sample pairs. The correction factor was applied to calculate the upper 95% limit of the TPU, which was thereby established to be 170 pCi/L. Given the limited sample population, the 2-u TPU values are preliminary and their robustness will increase with future monitoring events as more duplicate sample pairs are included in the analysis. As the number of duplicate sample pairs increases, the correction factor will decrease.Statistical analysis and verification of the June and September/October 2007 results for tritium are summarized in the following table: Value Concentration (pCi/L) Comment Up-gradient well 178 mean LLD from well MW- 10 Typical MDC 183 Reported result from well MW-31D 2-G TPU 170 Upper 95% confidence level Statistical decision level Data reporting convention (EPRI, 2005);348 sum of background well and 2-G TPU The TPU and the sub components of the TPU were evaluated for reasonableness and internal consistency. The data satisfy all quality requirement considerations. For the data presented here, individual measurements between 178 and 348 pCi/L represent statistically insignificant activity at the 95% confidence level.Individual measurement results above the decision level (i.e., 348 pCi/L)represent concentrations that are statistically greater than background and likely warrant additional monitoring. Monitoring wells where the net concentration was detected above the action level included MW-12D (738 ERM/DADE MOELLER 2 FIRSTENERGY -DAVIS-BESSE 0065992.218 MARCH 08 pCi/L), MW-15D (442 pCi/L), MW-30S (494 pCi/L), MW-31S (3,149 pCi/L), MW-35D (368 pCi/L), MW-102A LD (387 pCi/L), MW-102B (394 pCi/L), MW-103A (495 pCi/L), MW-103B (362 pCi/L), and MW-105A (1,832 pCi/L), (Table 7).ERM/DADE MOELLER 3 FIRSTENERGY -DAVIS-BESSE 0065992.2 18 MARCH 08 QUALITY ASSURANCE -QUALITY CONTROL

1.0 INTRODUCTION

This section presents a quality assurance and quality control (QA/QC)review of the Davis-Besse September/October 2007 groundwater sampling event. This evaluation was conducted to assess and enhance the reliability and validity of the groundwater analytical data. The verification process was conducted to identify the most common sampling and analytical problems that could affect the quality of the results. In general the results met the data quality objectives.

2.0 QUALITY

ASSURANCE Quality assurance involves planned and systematic actions necessary to provide confidence in the analytical results. The goal of the QA program is to have a program that is operating within acceptable criteria; thereby enhancing the representativeness and comparability of the results.Qualitative measures include items related to the field as well as the laboratory activities.

2.1 SAMPLING

PROGRAM The procedures used to collect the groundwater samples were detailed in a FSP (ERM, 20 September 2007). Specifications, such as well locations, well construction, sampling intervals, sampling and analysis techniques were items among others that were described to evaluate the representativeness of the groundwater samples collected. Groundwater samples were collected by personnel from the BETA Laboratory. Field notes were reviewed to assess if the procedures were executed properly.The following information reviews items were included in the field sampling quality assurance program.* Sampling documentation -The sample team maintained a field notebook (bound weatherproof logbooks) that was filled out at ERM/DADE MOELLER 4 FIRSTENERGY -DAVIS-BESSE 0065992.2 18 MARCH 08 each location where a sample was collected. It contains the sample V designation, collection time, description, and field instrument calibration log. The team also completed a Low-Flow Groundwater Sampling Form at each monitored location. The forms present information regarding location, weather, time, well construction, sampling depth, sampling device, field parameters and sample containers. The completed Low-Flow Groundwater Sampling forms are included within Appendix C." Sample Identification -Well IDs were used to identify the groundwater samples. The same codes were used to complete the chain-of-custodies (COCs). Duplicate samples were recorded as blind samples. Actual duplicate sample IDs were recorded on each Low-Flow Groundwater Sampling Form. COC records are included within Appendix C.* Decontamination -Dedicated high density polyethylene (HDPE)tubing was used at each location. Wells were sampled using either a peristaltic pump (30 wells, no decontamination required) or a bladder pump (2 wells, pump decontaminated after each use). An equipment blank sample was collected from the bladder pump after sampling at monitoring well MW-101C.* Calibration and Preventive Maintenance of Field Instruments -Sampling team personnel calibrated the geochemical parameter probe every day before starting the sampling. Calibration logs were maintained in the notebook.* Sampling locations -All locations were sampled as planned in the FSP." Gauging -A synoptic water level gauging round including all of the monitoring wells selected for the evaluation of tritium and gamma emitting radionuclides was performed on 24 September 2007 prior to sampling.* Sampling Depths -Sampling depths were reported on the individual Low-Flow Groundwater Sampling Forms. Sampling depths were consistent with sampling depths recommended in the Field Sampling Plan." Field Duplicates -All duplicate samples were collected in accordance with the FSP with the exception of sample duplicate DBD-04 that was taken at monitoring well MW-103B and not MW-ERM/ DADE MOELLER 5 FIRSTENERGY -DAVIS-BESSE 0065992.2 18 MARCH 08 104B because of the unexpected low groundwater elevation at MW-104B. This change did not affect the data quality.2.2 ANALYTICAL PROGRAM Groundwater samples were analyzed by Midwest Laboratory for analysis of tritium by EPA Method 906.0 and gamma emitting radionuclides by EPA Method 901.1 as specified within the FSP. Midwest Laboratory currently performs radiological environmental monitoring for over 20 nuclear power plants in 11 states. In addition, the laboratory is certified to perform analysis of drinking water for radionuclides in Illinois, Indiana, Wisconsin, and Kentucky. Midwest Laboratory maintains a Quality Assurance / Quality Control Program based on 10 CFR Part 50, Appendix B and Reg. Guide 4.15.3.0 QUALITY CONTROL The analytical data were assessed in terms of precision, accuracy, representativeness, comparability and completeness (PARCCs) to evaluate the usability of the results generated. Quality control items were evaluated through laboratory checks (e.g., matrix spikes, duplicate samples), and sampling method reviews (equipment blanks, trip blanks).In addition, Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of their quality control program in December 1971. Results of the interlaboratory program are presented at the end of this appendix.The following information provides background on the types of QC samples that were used to evaluate if the data quality objectives of the sampling program were met. Assessment of data quality based on compliance with PARCCs criteria is presented in the following. 0 Precision -United States Environmental Protection Agency (EPA)guidance suggests that the Relative Percent Difference (RPD) of field duplicates should be less than 30 percent in water samples.The RPD is calculated as: RPD -I Sample -Duplicate I (Sample + Duplicate) / 2 ERM/DADE MOELLER 6 FIRSTENERGY -DAVIS-BESSE 0065992.2 18 MARCH 08 Calculated RPD values for the tritium results were within guidelines and are presented in the following table.Field Duplicate RPD Calculations Sample Duplicate Sample Duplicate RPD ID ID Result Result MW-12D DBD-01 738 769 4 %MW-20S DBD-02 189 218 14 %MW-31S DBD-03 3,149 3,012 4 %MW-103B DBD-04 362 394 9%0 Accuracy -Matrix spike/matrix spike duplicate (MS/MSD), and laboratory control/ laboratory control duplicate sample are documented in the attached laboratory reports. These indicators are used to assess if the matrix may be biasing the reported results high (generally based on greater than 130 percent recovery) or low (generally based on less than 70 percent recovery). RPDs are generally expected to be less than 30 percent between MS and MSD results. As shown in the following table, all RPDs for tritium and cesium were within acceptable ranges.Matrix Spike/Matrix Spike Duplicate RPD Calculations Sample ID Compound MS/MSD Spike + Initial Sample RPD ID Sample Activities Result MW-30S Tritium MS1-17,185 16,321 5%MW-100A MSD01-MW-30S Tritium MW-bOA 17,185 16,925 2 %MW-100A MW-30S Cs-137 65.6 68.6 4 %MW-100A MSD01-MW-30S Cs-137 MW-bOA 65.6 70.2 7 %MW-100A MS0O2-MW-100A Tritium MW- 27,990 26,895 4 %MW-30S MW-100A Tritium MS0-27,990 26,895 4 %MW-30S MW-bA Cs137 MS02-MW-100A Cs-137 98.4 109.1 10 %MW-30S MSD02-MW-100A Cs-137 MW-30S 98.4 108.4 10 %MW-30S No Cesium was detected in the actual samples.

The absence of cross-contamination signifies that the reported results are most likely representative of groundwater quality at each monitoring well." Completeness -Based on review of sampling and laboratory check-in procedures, as well as field and laboratory QA/QC results, the data is considered to be complete and useable.* Sensitivity -The MDCs were consistent with data quality objectives (at least 200 pCi/L) as they ranged between 149 and 193 pCi/L for tritium and 1.4 and 14.4 pCi/L for the gamma emitting radionuclides, which allowed to establish if results were below site background. The 200 pCi/L value corresponds to an environmental level that would allow evaluating an eventual release of tritium to the environment.

Underground Storage Tank Overfill Release Report; Incident Number 6281145-00 The attached 'Twenty-Day' report is submitted to the Ohio State Fire Marshall's Office in accordance with Code of Federal Regulations (CFR) Title 40, Subchapter I, Part 280, Subpart F-Release Response and Corrective Actions for Underground Storage Tank (UST) Systems Containing Petroleum or Hazardous Substances, Section 280.62, paragraph (b).The report is submitted in response to an August 21, 1998 notification provided to the State Fire Marshall's Office of an overfill release of ajproxrimately, 50 gallons of diesel fuel from a registered UST at the Davis-Besse Nuclear Power Station. The UST is unique in that the tank is actually an above ground tank, however, it is registered as a UST because the tank is totally enclosed in an earthen bunker for missile shielding protection. The UST is part of an emergency generator system at a nuclear power generation facility regulated by the Nuclear Regulatory Commission under 10 CFR Part 50.The written report is the twenty-day follow-up report required after a release confirmation from a UST in accordance with 40 CFR 280.60 (b). The initial response and reporting requirement in accordance with 40 CFR Part 280 was confirmed by the Duty Officer(s) of the Ohio State Fire Marshall's office upon the verbal release notification. The report is included as Attachment 1, Twenty-Day Written Release Notification. Additional correspondence from your office dated September 1, 1998, was received by the Davis-Besse Nuclear Power Station on September 9, 1998. The release response cited in the September 1, 1998 correspondence was for a %suspected release', as defined in accordance with OAC 1301:7-9-13(B)(3), however, the release was a confirmed 'release' under actions of petroleum product transfer specifically defined in OAC 1301:7-9-13(B)(2)(b). Furthermore, the release was from an emergency generator system at a nuclear power generation facility regulated by the Nuclear Regulatory Commission under 10 CFR 50. Due to the nature of the release and the tank system, the Davis-Besse Nuclear Power Station does not agree to perform the activities referenced in OAC 1301:7-9-13 (D) and (E). However, excavated soil from the UST upon remnediation or closure will be managed as S Page 2 petroleum contaminated soil (PCS) unless laboratory analysis indicates otherwise, and a "Soil Disposal/Treatment Notification Form" will be provided to your office for PCS disposal activities. Reference Attachment 2, Response to September 1, 1998 Correspondence, for information addressing the supplemental request for actions.The only remaining documents required in this matter are the twenty-day letter included as Attachment I, and an agreement to provide the proper documentation to your office upon PCS disposal activities. Per your request on September 15, 1998, a photograph of the tank bunker is enclosed-Should you be in need of any further information, please contact Mr. Greg W. Gillespie, Superintendent-Chemistry at (419) 321-7268.Sincerely yours, C mes H. Lash Plant Manager Davis-Besse Nuclear Power Station KNM/bkk Attacmunents cc: Lowell Johannsen, Carroll Township Fire Department D. F. Petersen, Ottawa County Local Emergency Planning Committee ATTACHMENT 1 TWENTY-DAY WRITTEN RELEASE NOTIFICATION This report is submitted to the Ohio State Fire Marshall's Office in accordance with 40 CFR, Part 280-Technical Standards and Corrective Action Requirements for Owners and Operators of Underground Storage Tanks (UST), Subpart F-Release Response and Corrective Actions for UST Systems Containing Petroleum or Hazardous Substances. The written report is the twenty-day follow-up report required after a release confirmation from a UST in accordance with 40 CFR 280.62(b). The initial response and reporting requirement in accordance with 40 CFR Part 280 was confirmed by the Duty Officer(s) of the Ohio State Fire Marshall's office upon the verbal release notification of an overfill spill of approximately fifty gallons of diesel fuel.The notification was provided to the State Fire Marshall's Office on August 21, 1998, in response to an overfill spill from a registered UST at the Davis-Besse Nuclear Power Station, Oak Harbor, Ohio.This tank is part of an emergency generator system at a nuclear power generation facility regulated by the Nuclear Regulatory Commission under 10 CFR 50. Typically, USTs are underground storage tanks, however, this particular tank is a forty thousand gallon aboveground tank which is registered with the Bureau of Underground Storage Tank Regulators because it is completely enclosed in an above ground earthen bunker. The earthen bunker is for missile shielding protection requirements of the emergency generator system.The release was an overfill as defined in accordance with OAC rule 1301:7-9-13(B)(2)(b). Although the release was not into any nearby surface water nor released into the environment, the notification was made in accordance with Ohio Administrative Code (OAC) 1301:7-9-13(C) because the release was greater than twenty-five gallons and due to the nature of the security and integrity requirements of the tank and earthen bunker, removal and clean up of the soil in the spill area would not occur within twenty-four hours.In accordance with requirements of the twenty-day report, the following initial response actions were performed in accordance with requirements of Part 280.61, paragraph (a), (b), and (c), respectively: (I) The release notification was provided to the implementing agency (State Fire Marshall Office and Local Fire Department) within twenty-four hours of the release confirmation. (2) The release originated from an inadvertent overfill spill occurring during transfer of fuel into the tank during performance of a High Level Alarm calibration activity. Once the overfill condition was identified/the pumping of fuel into the tank was immediately terminated. The overfill resulted in fuel spillage from a vent pipe into an overfill drum stationed under the vent pipe, and on the top of the tank bunker. The spill area was contained to the stone overlay and earthen bunker on the top and a small portion of one side of the bunker. Site emergency procedures for spills were immediately activated. The spill area was immediately investigated for spill assessment and extent of release. Visual inspections verified the release was a sole result of the overfill and no further release threat to the environment existed from the tank. No evidence of runoff to any other ground or water system was identified during the initial visual inspections and assessments. S (3) The overfill product drum was appropriately closed and the work was terminated. No runoff to any other ground, groundwater or storm water system was evident, and no other free product, fire explosion, or vapor hazard was present.The following initial abatement measures and site checks were performed in accordance with Part 280.62 (a): (1) The initial assessment and incident initiator of manual overfill verified that product removal from the UST was not a requirement necessary to prevent further release to the environment. Additionally, periodic tank integrity testing has verified tank tightness. No other threat of release was probable or identified. (2) The type of soil surrounding the tank back-fill is clay substrate prohibiting the threat of migration into the ground or ground water. Visual inspections of the storm system area drain and out-fall verified that the fuel overfill was not released or migrating into surrounding soils or ground water, therefore, actions for further prevention of migration were not applicable. (3) In accordance with physical characteristics as described in response to paragraph (2) above, no additional fire and safety hazards posed by free product migration exists, therefore, monitoring and mitigation are not applicable. (4) The drum of overfill fuel generated from the vent spill has been removed and properly disposed in accordance with station and local requirements. The top layer of contaminated compacted stone overlay of the earthen bunker which is not removed (due to tank shielding integrity) will be bioremediated and managed in place and properly managed at site closure in accordance with the applicable state and local requirements. (5) and (6) In accordance with the incident description in Part 280.62 (a), the location and amount of the release is confirmed. Noadditional measurements or free product removal activities were required.The initial site characterization information as required in Part 280.63 (a), is provided as follows: (1) The nature and estimated quantity of the release was approximately fifty gallons of Number Two Fuel Oil originating from an inadvertent overfill during a High Level Alarm calibration activity. Once the overfill condition was identified, the pumping of fuel into the tank was terminated. The overfill resulted in fuel spillage from a vent pipe into an overfill drum stationed under the vent pipe, and onto the top of the tank bunker. The spill area was contained to the stone overlay and earthen bunker on the top and a small portion of one side of the bunker.(2) The climatological conditions were clear and fair at the time of the release and are not considered a factor in the release occurrence. The site meteorological data indicated a wind speed and direction of 5.65 miles per hour from the SSW (219 degrees) with 0.00 inches precipitation. The Davis-Besse Annual Environmental Operating Report (ABOR) was consulted to determine the following land and use characteristics of the area: soil conditions, water quality, and surrounding population. The Davis-Besse Nuclear Power Station site is mainly comprised of back-filled clay substrate with a small portion previously used for farmland. The surrounding area is mainly farmland or marsh and is sparsely populated. As reported in the AEOR for the facility, the 1990 census indicates the population for incorporated cormnunities within a 10 mile radius of the site are: Port Clinton, 10 miles southeast, population 7,106; Oak Harbor, 7 miles south, population 2,637; and Rocky Ridge, 7 miles southwest, population 425. The type of soil underlying the site back-fill is clay substrate which southwest, population 425. The type of soil underlying the site back-fill is clay substrate which prohibits the threat of migration into the ground outside of the site by runoff other than storm or sewer systems. The on-site storm sewer run-off for this area drains to an on-site holding pond and is routinely monitored. Site investigations verified no run-off to surrounding lands or ground or water systems occurred as a result of this release, and no subsurface or local wells are potentially affected by this release.(3) and (4) Not applicable, reference response provided to Part 280.62 (a) (5) and (6).Part 280.64, Free product removal activities are not applicable, reference response provided to Part 280.62 (a) (5) and (6).Part 280.65, Investigations for soil and groundwater cleanup, gre not applicable. Because the bunker is missile shield for an emergency system at a nuclear power generating facility, no borings were taken of the earthen bunker. Initial assessments performed at the time of the overfill, and re-verification inspections performed prior to initiating the required 24 hour notification to the State Fire Marshall, validated that the spill area, ground and surface water storm runoff systems had no evidence of aboveground release, noi did a threat of release into surrounding soils and groundwater exist.Part 280.66, Corrective action plan, and Part 280.67, Public participation, are currently not applicable. Responses to these sections are not part of this report.In accordance with 40 CFR 280.62, the report is due September 21, 1998, or twenty working days after the incident occurred. ATTACHMENT 2 S RESPONSE TO SEPTEMBER 1, 1998 CORRESPONDENCE On September 9, 1998, the Davis-Besse Nuclear Power Station received correspondence from your office dated September 1, 1998 requesting response actions supplemental to the twenty-day report submittal in accordance with 40 CFR 280.62 required by the Duty Officer(s) at the time of notification: The response cited in the correspondence dated September 1, 1998 was for a 'suspected release', as defined in accordance with OAC 1301: 7-9-13(B)(3), which required tightness testing results within 10 days of the incident and site check results within 60 days of the incident in accordance with OAC 1301:7-9-13 (D).Actually, the release was a confirmed 'release' under actions specifically defined in accordance with OAC 1301:7-9-13(B)(2)(b). Furthermore, the release was from an emergency generator system at a Nuclear Power Station regulated by the Nuclear Regulatory Commission (NRC) under 10 CFR 50. Due to the nature of the spill and the maintenance and integrity requirements for the system, the Davis-Besse Nuclear Power Station does not agree to perform the activities referenced in OAC 1301:7-9-13 (D) and (E). However, a site assessment was performed in conjunction with the requested twenty-day written report in accordance with 40 CFR 280 (F) and is included in this correspondence (reference Attachment I).In addition to the written release response requested August 21, 1998, the following information is also provided for actions requested in your correspondence datedSeptember 1, 1998.(1) Regarding the tightness test referenced in OAC 1301: 7-9-13 (D) (1), due to the nature of the tank system, periodic integrity testing of the tank system includes tightness testing, .and.u.rent testing.._ results verify the tank is of sound integrity. In addition, the cause of the release was visually and positively identified as an overfill spill in accordance specified activities listed in 1301: 7-9-13 (B)(2)(b) and was not a function of the tank integrity, therefore, additional tank tightness testing was not warranted. (2) Regarding drinking water well analysis referenced in OAC 1301:7-9-13(D) (2), in consideration of the nature and extent of the release, visual inspections and assessments performed at the time of the release, and the physical characterizations and distance of the release site in relation to any surrounding property drinking water wells, more than sufficient evidence is provided to demonstrate that the release will not impact a drinking water well on a nearby property.(3) Regarding the site check in accordance with OAC 1301:7-9-13(D) (3), the nature and functional requirements of the tank system and inherent bunker shielding requirements prohibit borings on the tank earthen bunker. Additionally, site investigations and the nature and extent of the release demonstrated that migration of the spill did not occur.(4) Regarding action levels referenced in OAC 1301:7-9-13 (E)' (3), as described in response (3)above, no borings were performed, therefore, comparisons with the action levels based upon Site Feature Scoring System (SFSS) were not performed. The SFSS work sheet is not included, however, the SFSS is estimated as 70 based upon scoring system in section 1301:7-9-13(D) (3).Site details as listed in response to 40 CFR 280.63 (a) of Attachment I detail the site characteristics. (5) Ihe UST is part of an emergency generator system at a nuclear power generating facility regulated by the United States Nuclear Regulatory Commission, and is exempt from OAC 1301:7-9-07 (E).(6) Excavated soils will be managed as petroleum contaminated soils (PCS) unless laboratory analysis indicates otherwise, and the soil will be properly disposed in accordance with state and local regulations. A Soil Disposal/Treatment Notification form will be submitted to your~office as required for PCS disposal activities.

Reporting and Event Summary Question: a) Time, date and duration of release or discharge. b) Time and date of discovery of the release or discharge. c) Indicate the Ohio EPA spill number and the National Response Center case number.d) Provide an event summary.Response: a) The actual time, date and duration of the release is unknown. The release most likely occurred between approximately 0300 hours on-....-January-16,-1994,- (the-last recorded-vehicle refueling) and.1130 hours-January 17, 1994 (the first recorded observation of pump malfunction). b) The actual time and date of discovery of the release of gasoline was approximately 1800 hours on January 18, 1994.c) The Ohio Environmental Protection Agency Spill Response Number is 01-62-0180. The National Response Center Number is 217385.d) On Monday, January 17, 1994, approximately 1300 gallons of gasoline were found missing from the above ground gasoline storage tank at Service Building 4. The gasoline is used to service site vehicles; pool cars, snow plows, etc. On the morning of January 17, the gasoline pump appeared to be malfunctioning. Gasoline was pumped from the tank and about eight gallons were pumped and the flow stopped. The storage tank level was checked and measured approximately 100 gallons. The measurement of the tank on Friday, January 14, indicated approximately 1470 gallons with 88 gallons being dispensed over the weekend. The last gasoline was pumped from the tank on January 16, 1994, at 0300 hours.Industrial Safety and Environmental were notified of the missing gasoline. The site was checked for indications of a gasoline spill.There was no evidence of gasoline in the concrete dike surrounding the tank, or of any amounts around the gasoline pump or inside the pump housing, or in any of the areas' storm water outfalls (i.e., marsh or ponds). No gasoline odors were present. Security was notified for potential theft investigation. On January 18, 1994, the tank and underground piping to the gasoline pump were pressure tested with no evidence of any leaks. The gasoline tank was partially filled and the pump was tested by pumping gasoline through the pump. When the pump was stopped, gasoline was observed to be siphoning through the gasoline pump fire safety valve's atmospheric vent.This leak path was established when a diaphragm failed in the fire safety valve. This confirmed that the gasoline had been released to the environment, not stolen as was previously suspected. It is suspected that the fire safety valve's diaphragm failed due to the extremely cold RAOG 94-09 Enclosure Page 2 weather on January 16, 1994, and at 0300 hours, when the pump was last used, gasoline siphoned through the atmospheric vent until the pump's suction was uncovered (100-gallon tank level).At 1800 hours on January 18, 1994, notifications were made in the following sequence: the National Response Center, the State Emergency Response Center, and the Ottawa County Sheriff's Department as required for the local fire department and local emergency planning committee notifications. At approximately 2120 hours on January 18, 1994, the OEPA Division of Emergency and Remedial Response representative arrived onsite and inspected the spill area.Collection activities to date have recovered approximately 500 gallons of gasoline and determined how far the gasoline has spread. The gasoline is contained in the porous fill underneath the Service Building 4 parking lot and poses no environmental concerns as it has not entered the marsh area, and is confined within Toledo Edison's property. The leak has been isolated and repaired. See Attachment 2 for a sketch of the incident scene .-- -...2. Location Question: a) Location of the facility from which the release or discharge occurred.b) Location of the release or discharge. c) Longitude and latitude Response: a) Toledo Edison Company Davis-Besse Nuclear Power Station 5501 North State Route 2 Oak Harbor, Ohio 43449 b) Ottawa County Carroll Township Oak Harbor (nearest village)c) The longitude and latitude of the Davis-Besse Nuclear Power Station is 410 36' N, 830 05' W. Attachment 1 contains a map showing the site location. The release was not transportation related.01 RAOG 94-09 Enclosure Page 3 3. Product Release Question: a) Chemical name (common name or technical name) and Chemical Abstracts Service (CAS) registry number of the substance involved in the discharge or release.Response: a) The material released was Gasoline, BP Super Unleaded (No CAS Number is available because the product is a mixture). The Material Safety Data Sheet (MSDS) is attached (Attachment 5). The material is not an extremely hazardous substance. The estimated release quantity was approximately 1300 gallons.4. Environmental Impact Question: a) Identify the environmental medium or media impacted an~dthe extent of_the impact.Response: a) The gasoline was released into the soil underneath the gasoline pump.The estimated area of contaminated subsurface soil is 2500 square feet.There appears to be a zone of gasoline-contaminated soil approximately.six inches wide. This zone is approximately three feet below the ground just above the clay substrate. The spill is 400 feet from the nearest waterway, no navigable waterways have been or are anticipated to be affected.Collection activities to date have recovered approximately 500 gallons of the gasoline and determined how far the gasoline has spread. The gasoline is contained in the porous fill underneath the Service Building 4 parking lot and poses no environmental concerns as it did not enter the marsh area and was confined within Toledo Edison's property.Additionally, the soil beneath the porous fill material is composed of a clay substrate which Is very dense and has prevented the gasoline from migrating deeper. Area storm water drains have been isolated to prevent the potential of the gasoline from being released off site.5. Monitoring and Detection Question: a) If the release or discharge was monitored, indicate the method of detection and concentrations. RAOG 94-09 Enclosure Page 4 Response: a) As described in Section l.d., Event Summary, the gasoline leak is thought to have occurred during the weekend of January 15 and 16, 1994.The release path to the ground is not a monitored pathway and was unnoticed by site personnel. For event detection specifies, refer to Section 1.d., Event Summary.6. Mitigation and Containment Action Question: a) Amount recovered or neutralized. b) Describe any actions taken to reduce the impact of the release or discharge. c) Actions taken to respond and contain the release or discharge. Response: a) To date, approximately 500 gallons of gasoline have been recovered from the gasoline recovery sumps that were dug to collect the gasoline, and storm water oil interceptors. These low collection points are being monitored and the material is being collected throughout the remediation process.b),Weather conditions (-IOF) predicted a low probability of migration at c) the time of the release. The storm water line oil interceptors were pumped out for initial recovery. Recovery sumps were dug to recover additional bulk gasoline which may be present and to determine how far the gasoline had spread. Attachment 2 contains a sketch of the incident scene. Approximately 500 gallons of gasoline has been recovered to date. Gasoline recovered from the recovery sumps has slowed. The remaining gasoline appears to be contained in the porous fill beneath the parking lot. Additionally, the storm water lines have been plugged to prevent any gasoline from leaving the site from this pathway. Further remediation activities to remove the residual gasoline contamination from the soil are currently being evaluated.

Dear Mr. Rick Zuzik:

Re: National Pollutant Discharge Elimination System Permit Renewal Application Davis-Besse Nuclear Power Station, EPA ID No. OH0003786 Permit No. 21B0001 lID Enclosed are two copies of completed Form 1, Form 2C, and Form 2F applications for FirstEnergy Nuclear Generation Corp. (a subsidiary of FirstEnergy Corp.) Davis-Besse Nuclear Power Station's National Pollutant Discharge Elimination System (NPDES) permit renewal.These forms are submitted 180 days prior to expiration of the existing permit in accordance with OAC-3745-33-04. Also enclosed is check number 1374125 for $200.00 for payment of the application fee.The following are additional items pertinent to the application and/or permit renewal: 1. Samples for Storm Water Outfalls 002 and 006 have been collected and analyzed, with the results reported on Form 2F. The collection of the Outfall 005 sarnple has not occurred to date due to no flow conditions during the sampling event. Results for Outfall 005 will be reported on Form 2F Item VII when available.

2. The asbestos monitoring results have been below detection at Outfall 004 since quarterly sampling was initiated in September 2006. Therefore, it is requested that the monitoring for asbestos be removed from the renewal permit, and also, that the corresponding Item 0 in Part II, Other Requirements, be removed. It is also requested that the metals monitoring requirement at Outfall 004 be removed.3. Presently the pathway for the discharge of Outfall 004 is to the State Route 2 ditch, which is then pumped into the Navarre Marsh Pool #1, along with other local area storm water run-off. It is requested that the facility have the option to discharge Outfall 004 to the Navarre Marsh Pool #1. when flooding or pump maintenance is occurring to alleviate high water levels on neighboring properties.

Mr. Rick Zuzik Davis-Besse Nuclear Power Station Page 2 of 2 L-10-287 October 21, 2010 4. Sampling has indicated that dissolved oxygen is not an issue at Outfall 001. Therefore, it is requested that further sampling of dissolved oxygen be removed from the permit.If you have any questions, please contact me at (330) 384-4643.Sincerely, Scott F.

Outfall 002 (Training Center Pond Discharge)

a. Chemnical Waste Storage Areas (CWSA)The CWSA is an enclosed structure with a curbed concrete pad to contain any potential leaks. The pad is divided into three separate sections as follows: 1)hazardous waste, 2) waste oil and non-hazardous wastes, and 3) chemical identification.

In the event of a large quantity leak, the flapper gates for the drainage ditch behind the facility can be closed to isolate the spill. Also, the CWSA is inspected on a weekly basis.b. Chemical Waste Accumulation Areas (CWAA)There are two CWAAs In this stormwater discharge area. These two CWAAs are only for diesel fuel. They each consist of two 55-gallon drums contained In the water-tight plastic storage containers.

c. Sodium Hypochlorite (NaOCI) Tank The NaOCI tank, which Is located at the site water treatment plant, has a maximum capacity of 7,500 gallons and contains a 15% solution.

This tank has a dike structure designed to contain 115% of the tank capacity.d. Sodium Bromide (NaBr) Tank The NaBr tank, located at the Water Treatment Plant, has a 4,500 gallon capacity and contains a 43% solution.
