Peach Bottom Atomic Power Station NRC Request for Additional Information - Response Sheet Question: RAl-AL-2 Category: Alternatives, Replacement Power ER Section: 7.2.3.1/ 7.2.3.2/ 7.2.3.4 Statement of Question: Has Exelon Generation estimated the cooling water make-up and consumptive water use associated with the Natural Gas-Fired, Coal-Fired, and Small Modular Reactor alternatives presented in ER Sections 7.2.3.1, 7.2.3.2, and 7.2.3.4, respectively? If yes, please identify these estimates and the basis used to determine them.
Response
Exelon Generation did not quantitatively estimate the cooling water make-up and consumptive water use associated with the Natural Gas-Fired, Coal-Fired, and Small Modular Reactor alternatives. As is stated in the ER Table 7.2-1, these alternatives were assumed to generate approximately the same amount of electricity as PBAPS and to use closed-cycle mechanical draft cooling towers for condenser cooling, making their consumptive water demands similar. It was also assumed that any differences in consumptive water use among PBAPS and these alternatives would not be a distinguishing factor.

Peach Bottom Atomic Power Station NRC Request for Additional Information - Response Sheet Question: RAl-AQ-1 Category: Air Quality and Meteorology ER Section: 3.2 Statement of Question: Section 3.2 of the ER discusses three instrumented meteorological towers supporting the PBAPS site: Tower 2, the River Tower, and the Hill Pole. Please clarify the current purpose, status, and instrumentation associated with each of these towers.
Response
The Hill Pole has been retired from service. The wind speed and direction instrumentation located on the Hill Pole was upgraded and relocated to an equivalent 33-ft position on Tower No. 2, which has been renamed as either the "Main Meteorological Tower" or the "Microwave Tower." The upgraded wind speed and direction instrumentation is referred to in its location on the Main Meteorological Tower (formerly Tower No. 2) as the "Met Tower Back Up" instrumentation. Data from the Met Tower Back Up instrumentation is digitized and recorded in the same manner and for the same purpose as was data from the old wind speed and direction instrumentation on the Hill Pole. The purpose, status, and all other instrumentation associated with the Main Meteorological Tower (formerly Tower No. 2) and the River Tower have not changed from the descriptions provided in the ER Section 3.2.

Response
Year 2013 2014 2015 2016 2017 The following table provides PBAPS air emission data for tracked pollutants from the most recent 5 years for which data are available. These data demonstrate that PBAPS operates well below the major source threshold emission limits shown in ER Table 3.2-1. All discrepancies in data that were reported in response to Audit Needs Question AQ-2 and discussed between NRC and Exelon staff during the onsite environmental audit held November 7 to 8, 2018 are gone from the revised data presented in the table below.

Peach Bottom Atomic Power Station NRC Request for Additional Information - Response Sheet Question: RAl-A-1 Category: Aquatic Resources ER Section: 2.2.3 Statement of Question: Section 2.2.3 of the ER describes a high-pressure spray back-wash system that may allow some impinged or entrapped fish to return to the Conowingo Pond. Please clarify whether a fish handing and return system exists near the inner or outer intake structure or within the intake canal. In addition, please clarify whether fish can travel from the intake canal back to Conowingo Pond through the discharge canal or any other swimmable route.
Response
Neither the inner nor outer intake structure traveling screen system is equipped with a fish handling and return system. Screen wash water at the outer intake structure is returned to Conowingo Pond, and screen wash water at the inner intake structure is returned to the intake pond. Debris from the screens at both intake structures is collected and disposed offsite at a permitted landfill. A cross tie gate, with fish screen, is installed between the Unit 2 intake canal and the discharge pond. This cross tie exists to provide recirculation of heated water from the discharge canal to the intake canal during winter months for minimizing frazil ice formation. It also could provide a backup water supply to the intake pond if the outer screen structure should become clogged. During periods when the cross tie is opened, water flows from the discharge canal into the intake canal at rates not conducive to fish travel in the opposite direction, and the fish screen provides a barrier to such interaction as well. Accordingly, no significant interaction results from this arrangement, and there are no other swimmable routes through which fish can travel from the intake canal back to Conowingo Pond through the discharge canal.

Peach Bottom Atomic Power Station NRC Request for Additional Information - Response Sheet Question: RAl-A-2 Category: Aquatic Resources ER Section: 2.2.3 Statement of Question: Section 2.2.3 of the Environmental Report describes traveling screens on the inner and outer intake structures. The ER also provides information regarding the mesh size, the approach velocity, and the through-screen velocity for the traveling screens on the outer intake structure. Please describe the mesh size, the approach velocity, and the through-screen velocity for traveling screens on the inner intake structure.
Response
For compliance by existing facilities with Clean Water Act, Section 316(b), the term "cooling water intake structure (CWIS)" is defined in 40 CFR §125.92(f) as follows: Cooling water intake structure means the total physical structure and any associated constructed waterways used to withdraw cooling water from waters of the United States. The cooling water intake structure extends from the point at which water is first withdrawn from waters of the United States up to, and including, the intake pumps. When this definition is applied to the existing PBAPS Units 2 and 3, the PBAPS "cooling water intake structure" extends from the river-side of the outer intake screen house through the inner intake screenhouse to the outlets from the six circulating water pumps. In this configuration, the outer intake is an undivided operational arrangement of components within the larger PBAPS "cooling water intake structure." The outer intake results in velocity reductions and reductions of fish entrapment, and it was installed to reduce impingement mortality. The traveling screens at the inner screenhouse are also undivided components of the PBAPS "cooling water intake structure" that were installed to prevent debris from entering the circulating water pumps. Hence, because the inner intake screenhouse is not a separate "cooling water intake structure," the approach velocity and through-screen velocity have not been determined for the inner intake traveling screens, which are dual-entry, single-exit (dual-flow) traveling screens, with 3/8-inch mesh.

Some of these conditions provide options for Exelon to select from. For example, the following are the conditions that address impingement and entrainment: A. The PBAPS cooling water intake structures must meet BTA [best technology available] standards for impingement mortality by employing one of the alternatives in 40 CFR §125.94(c)(1) through (c)(7). Additional measures may be required to protect federal or state threatened and endangered species and fragile species. Please describe which of the alternatives in 40 CFR §125.94(c}(1) through (c)(7) Exelon has selected to implement since 2014.
Response
In the Comment/Response Document for Draft NPDES Permit No. PA0009733 (August 22, 2014), which was an enclosure to the PADEP letter dated September 22, 2014 issuing the final PBAPS NPDES Permit, PADEP explained that PBAPS is required to consider the seven methods for compliance with the impingement mortality BTA standard in 40 CFR §125.94(c}. However, PADEP further explained that PBAPS must also provide necessary information to develop site-specific entrainment BTA requirements (NPDES Permit No. PA0009733, Parts C.11.B and D), and that PADEP would evaluate such information using Best Professional Judgement to determine appropriate technologies, management practices, and operating measures that are considered the BTA for impingement and entrainment reductions at PBAPS. NPDES Permit No. PA0009733 indicates in Parts C.11.B and E that PSAPS must submit the necessary information, which is defined in 40 CFR §122.21(r)(2) through (13), to PADEP "with the subsequent permit application." Pursuant to 40 CFR §122.21 (r)(6) and (9), PSAPS completed biological data collection in October 2018 and is analyzing the data. Once all data have been analyzed, PSAPS will prepare, as part of the §122.21(r) reports, an Impingement Characterization/Mortality Study and Entrainment Characterization Report, which will be the basis for a compliance technology selection. Using this and other §122.21(r) reports, PSAPS will recommend a compliance alternative for impingement mortality STA from among those listed in 40 CFR §125.94(c)(1) through (c}(7}. All reports, including the recommended impingement mortality STA compliance approach, will be submitted to PADEP with the PSAPS NPDES permit renewal application on or before March 30, 2019. The reports will also be available to other appropriate agencies through their participation in the NPDES permit renewal process. A-4

Please provide documentation if the Pennsylvania Department of Environmental Protection (PADEP) has approved any changes to the conditions within the NPDES permit as it was described in the ER.
Response
Pursuant to Part C.I of NPDES Permit No. 67-05020, PBAPS developed and implemented a PADEP approved plan," Study Plan for Post-EPU Thermal and Biological Monitoring." The information from the study was collected, analyzed and submitted to PADEP for their review in February 2017. Subsequently, the agency requested that PBAPS continue the study to validate the assumptions of temperature increase associated with the measurement uncertainty recapture (MUR) uprate (Reference 1 ). Data from the extended study are being routinely collected and an analysis will be submitted with the NPDES permit renewal application in March 2019 to support continuation of the existing CWA §316(a) thermal variance. No permanent plant modifications have been completed in association with or as a result of biological and thermal monitoring since the PBAPS Second License Renewal Environmental Report was prepared. A temporary modification of the outer intake screen backwash system has been implemented to allow a supply of cooler backwash water to the Unit 2 traveling screens during impingement monitoring. No amendment of the NPDES permit was required for this temporary modification (Reference 2). Additionally, the results of water temperature and certain biological monitoring conducted during upstream and downstream fish migration seasons are being reported annually by the Conowingo Hydroelectric Project to the Federal Energy Regulatory Commission (FERC) pursuant to a FERG Order issued September 2, 2015 (Reference 3). Such reporting will continue through at least 2020. If anticipated discharge temperatures are exceeded or if any adverse impacts to migrating fish are observed, response measures will be implemented.

This lett~r is in reference to the final report for Post-EPU Thermal and Biological Monitoring and notice of Planned Measurement Uncertainty Recapture Uprate recently submitted by Exelon Generation Company LLC (Exelon) to support compliance with the existing pennit requirements developed under Section 316(a) of the Clean Water Act (CWA). The Department of Environmental Protection (DEP) has reviewed these documents and would like to provide the following comments: Final Report for Post-EPU Thennal and Biological Monitoring In accordance with Part C.I of the above-referenced NPDES permit reissued in 2014, a study plan was developed to perform one-year biological and thermal monitoring1 in order to evaluate the impact on the fish and macroinvertebrate populations in the Susquehanna River as a result of thennal component of the discharge from the above-referenced facility following implementation of the extended power uprate {EPU) which was completed in 2016. The study was also determined to be necessary to compare post-EPU conditions with predictions, such as the characteristics of the plume, made in the previous monitoring study pe1formed during the period from 2010 through 2013 (i.e., demonstration study;finalized in 2013). A review of the submitted final report for 2016 Post-EPU Thermal 'and Biological Monitoring revealed that Exelon has adequately implemented the monitoring plan through this one-year study and bas addressed all of the components of this study in the final report. DEP bas therefore detennined that Exelon has achieved compliance with the existing pe1mits requirements and continuation of CWA S~ction 316(a) thennal variance is still warranted for the current NPDES permit tenn. DEP appreciates Exelon' s efforts to collect extensive physical and biological data to support the monitoring requirements. While continuation of the thermal variance is warranted for the 1 Temperature monitoring from May 1 through September 30 of2016, Dissolved Oxygen monitoring from July 1 through August 31 of2016, Biological monitoring May l through September 30 of 2016.

Mr. Patrick remainder of currenl permit cycle, DEP strongly recommends that Exelon consider operation of the cooling towcr(s) until the end of September of each year. No cooling towers were operated in Seplembcr 2016 as it was not required by the pennit. For many of the downstream monitoring stations, several year-to-year analyses in the final report show that daily average water temperatures in September 2016 were wanner than temperatures measured in September of previous years. .Furthermore, Lemperature differences from the intake tQ the downstream monitoring station 214 in September were mostly higher than those calculated for any of the months within the 2016 monitoring period. For macroinvertebrate community, Exelon concluded, along with other findings, Lhal a temporary impact, in tenns of lower IBI scores, was observed at two (2) downstream monitoring stations in September. All of above-mentioned items were identi fled during the monitoring period presumably due to the unusual ambient river conditions observed in September 2016 that were repeatedly mentioned in the fmal report (i.e., very low-flow with high ambient water temperatures). However, the final report indicates that the average temperature rise from the intake to the head of discharge canal in September 2016 was higher than previously predicted in the demonstration study (i.e., 22.S°F v. 22.4°F; Table 3-5 of the final repo1t). As a result, higher water temperatw*es were observed at the downstream monitoring stations not only because of unusual river conditions occurred in September but possibly because of additional thennal load potentially generated from the facility. In order to protect the aquatic community, the operation of the cooling tower(s) may be necessary during any of nat.urally-occurring high temperature periods to additionally "balance" the thermal load generated from PBAPS..Exelon observed during the monitoring period that the per tower discharge canal cooling was higher than previously expected in the demonstration study (i.e., 2.2°F v. l.6°F); therefore, using the cooling tower(s) additionally in September will further mitigate potential impacts on the fish and macroinvertebrate populations in the Susquehanna River as a result of thermal component of the discharge. This final report as well as any relevant information provided by Exelon will be considered in developing appropriate pennit requirements for the subsequent NPDES permit renewal. Notice of Planned Measurement Uncertainty Recapture Uprate As per reporting requirements set forth in Part A.III.C.2.b ofthe*above-referenced NPDES permit reissued in 2014, Exelon bas indicated via a letter dated February 17, 2017 that additional thennal loading is expected as a result of a Measurement Uncertainty Recapture (MUR) uprate of PBAPS Units 2 and 3. The MUR uprate, in which the license amendment is scheduled to be submitted to the NRC hy the end of February 2017 according to the February 17, 2017 letter, will increase the station's licensed power level from 3951 MWth (megawatt thermal) to 4016 MWth. It is expected that this change will ultimately result in a plant intake to discharge temperature (At) increase of up to 0.4°F over current conditions2 and the net temperature increase at the near field temperature stations downstream of the plant would range from 0.02°F and 0.06°F over the EPU model. Based on the* given information, DEP has determined that the MUR uprate is not expect~d to significantly 2 The February 17, 2017 lettcrdocwnented that the net increase projected for MUR will be only O.I 0P u the actual maximum net tcmP.Crature under EPU conditions was detennined to be 22.1 °F as opposed to 22.4 °F which is the value predicted during the Section 316(a) demonstration study.
Mr. Patrick MAY 0 3 2017 contribute to additional thennal impacts on the Susquehanna River. Consequently, no NPDES permit amendment is required at this time. However, because the expected ill value was dctennined solely based on assumptions detennined through the application ofEPU model, DEP requests that temperature monitoring be conducted following implementation of the uprate to validate such assumptions. Given that the uprate is sched~led for April, 2018 according to the February 17, 2017 letter, DEP is requesting that Exelon to submit the one-year monitoring data with the subsequent NPDES pcnnit renewal application which is due by April, 2019. Section 316(a) Thennal Variance Request Pursuant to 40 CFR §122.210)(6), a request for a variance under CWA Section 316(a) for the thermal component of the discharge must be filed with a timely NPDES permit renewal application. If such request will be submitted with the NPDES permit renewal application, please contact DEP to discuss any additional information that may be necessary for DEP to evaluate continuation of CWA Section 316(a) thermal variance for PBAPS during the subsequent NPDES pennit renewal application review process. If you have any questions, please contact me at 717.705.4795 or mbebenek@pa.gov. Sincerely,

Dear Mrs. Bebenek,
lb.lo I cW. jv.3 This letter is a notification regarding Peach Bottom Atomic Power Station's (PBAPS) plan to perform a temporary modification of our Outer Screen Structure backwash system for the purpose of performing Clean Water Act (CWA) 316b impingement sampling. This modification will allow a supply of cooler river intake water for the backwash of the Unit 2 traveling screens in order to determine fish impingement mortality from the screens without thermal influence from the current discharge pond supply. This modification is planned to be installed this year to support the Impingement sampling results needed to support a CWA 316b Best Technology Available (BTA) determination. This determination will be provided to PA DEP as part of the next NPDES permit ~enewal. We understand based on discussion with Jin Su Kim that since this change is temporary for the purpose of CWA 316b sampling the change does not require a permit modification.

20150902-3052 FERC PDF (Unofficial) 09/02/2015 152 FERC if 62,142 UNITED STATES OF AMERICA FEDERAL ENERGY REGULATORY COMMISSION Exelon Generation Company, LLC Project No. 405-113 ORDER MODIFYING AND APPROVING NON-PROJECT USE OF PROJECT LANDS AND WATERS (Issued September 2, 2015)
- 1.
On May 1, 2015, Exelon Generation Company, LLC (licensee), licensee for the Conowingo Hydroelectric Project, FERC No. 405, filed an application for non-project use of project lands and waters for Federal Energy Regulatory Commission (Commission) approval, pursuant to standard Article 13. In its application, the licensee proposes increases to the permitted water withdrawal and consumptive use amounts from the Conowingo Reservoir for use at Peach Bottom Atomic Power Station (Peach Bottom), which the licensee co-owns. The Conowingo Hydroelectric Project is located on the Susquehanna River in Cecil and Hartford counties, Maryland and Lancaster and York counties, Pennsylvania. Peach Bottom is located in York County, Pennsylvania. LICENSE REQUIREMENTS AND BACKGROUND
- 2.
The Commission issued a license for the Conowingo Hydroelectric Project to Susquehanna Power Company and Philadelphia Electric Power Company on August 14, 1980.1 The Commission approved the transfer of the project license to Exelon on November 24, 2008.2 The project license expired on September 1, 2014; however, the project continues operation under an annual license pending Commission action on Exelon's relicensing application.
- 3.
The project primarily consists of a concrete gravity dam, powerhouse, and reservoir, and it is the last impoundment on the Susquehanna River, at river mile (RM) 1 Order Issuing New Major License. 19 FERC if 61,348 (1980), and the Order on Rehearing. 13 FERC if 61, 132 (1980). Due to an oversight the 1980 Order Issuing New Major License for the Conowingo Project was published subsequent to the Order on Rehearing. 2 Ordering Approving Transfer of License. 125 FERC if 62,181 (2008).
20150902-3052 FERC PDF (Unofficial) 09 /02/2015 Project No. 405-113 10, before discharging into the Chesapeake Bay. The reservoir extends upstream 14 miles from the dam and has an average depth of 20 feet. The project operates as a peaking facility, and the licensee is authorized to operate the reservoir between 101.2 and 110.2 feet National Geodetic Vertical Datum (NGVD). However, the licensee typically maintains the reservoir at 109.2 NCVD, but always above 105.2 NGVD to ensure that the upstream (RM 22) Muddy Run Pumped Storage Hydroelectric Project (Muddy Run), FERC No. 2355, is able to operate. The Conowingo reservoir serves as the lower reservoir for Muddy Run.
- 4.
There are five existing water withdrawal and consumptive use permits that utilize water from the Conowingo reservoir. In total, the City of Baltimore, Chester Water Authority, Connective Mid Merit, LLC, and Old Dominion Electric Cooperative are allowed to consume 296.62 million gallons per day (mgd). The fifth authorization permits the licensee to withdraw 2,236.264 mgd and to consume 35.5 mgd for the purpose of operating Peach Bottom.3 The licensee currently employs a single, 15-foot diameter submerged pipe to convey water between the Conowingo reservoir and Peach Bottom. The 1,450-foot-long pipe is located on a 20-foot-wide strip of crushed rock, approximately 15 feet below the normal reservoir elevation. LICENSEE'S PROPOSED ACTION
- 5.
The licensee's May 1, 2015 filing requests that the Commission approve increases in the permitted water withdrawal and consumptive use amounts for cooling water needed for the operation of Peach Bottom. Specifically, the licensee requests an increase in the permitted water withdrawal from 2,236.264 mgd to 2,363.62 mgd and in the consumptive use from 35.5 mgd to 49.0 mgd. The licensee indicates that it would use the existing project infrastructure to implement the requested increases. Accordingly, it does not anticipate that any construction or modifications to project operations would be necessary to accommodate the request.
- 6.
The licensee's filing also assesses the potential for fish impingement and entrainment at the project intake using the proposed withdrawal rate increase. The licensee indicates that the approach velocity would be 0.75 feet per second (fps) and the through-screen velocity would be 1.21 fps. The intake facilities consist of 24 single-entry, single-exit traveling water screens on the outer intake structures. The licensee's filing reaffirms that the outer screen of the intake structure was designed with a low approach velocity specifically to reduce the impingement and entrainment of aquatic organisms. 3 Order Approving Use of Project Lands and Waters. 55 FPC 2607 (issued June 1, 1976).
20150902-3052 FERC PDF (Unofficial) 09/02/2015 Project No. 405-113 CONSUL TA TI ON
- 7.
Prior to filing its May 1, 2015 request with the Commission, the licensee consulted with the Susquehanna River Basin Commission (SRBC), 4 which was established to facilitate public interest in issues concerning the Susquehanna River Basin and its associated water resources. The SRBC indicated that it does not anticipate adverse impacts associated with the proposed withdrawal increase, and it approved the proposed increases on June 23, 2011.
- 8.
The licensee received a National Pollutant and Discharge Elimination System Permit (NPDES, No. PA 0009733) from the Pennsylvania Department of Environmental Protection (PDEP), effective January 1, 2011 through May 31, 2015. On September 22, 2014, the PDEP renewed this permit through September 30, 2019, after providing a public notice on July 5, 2014 and allowing a 30-day comment period. The permit includes a record of consultation between the licensee, PDEP, U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service (FWS), and Pennsylvania Fish and Boat Commission (PFBC).
- 9.
The licensee currently withdraws water for use at Peach Bottom under the PDEP's July 23, 2014 Water Quality Certification. During the PDEP's review of the licensee's application, it determined that the primary impacts of withdrawing water from the Conowingo Reservoir would be to aquatic resources and include the physical loss of water from the withdrawal and consumption, and thermal impacts of the water returned to the reservoir.
- 10.
The licensee also repeatedly consulted with the Nuclear Regulatory Commission (NRC) regarding its request, initially on February 28, 2012. On August 25, 2014, the NRC approved the proposed withdrawal increase. 5 The NRC's Environmental Assessment, which found no significant impacts, was published in the Federal Register on March 31, 2014.
- 11.
As a part of its application process for the NRC, on January 22, 2012, the licensee also requested input from the Pennsylvania Department of Conservation and Natural 4 The SRBC was established pursuant to the Susquehanna River Basin Compact of 1970, with duties and responsibilities for comprehensive planning, water supply allocation, programming, and management of the water and related resources of the Susquehanna River Basin by all three states involved (Maryland, New York, and Pennsylvania) and with the federal government. 5 Peach Bottom implemented the additional water withdrawal prior to Commission approval. This action is being reviewed under a separate Commission proceeding.
20150902-3052 FERC PDF (Unofficial ) 09/02/2015 Project No. 405-113 Resources (PDCNR) regarding potential environmental effects of the proposed withdrawal and consumptive use increases. The PDCNR provided recommendations on February 21, 2012 describing how the licensee could conserve sensitive plant habitat but ultimately determined that it does not anticipate any adverse impacts from the proposed mcreases.
- 12.
On January 23, 2013, the licensee formally requested input from the PFBC and the Pennsylvania Historical and Museum Commission (PHMC) as a part of the NRC application process. Previously, on February 8, 2012, the PHMC had indicated that, while archaeological resources likely exist in the area, the proposed modifications would not impact such resources. On February 24, 2012, the PFBC further indicated that it does not expect adverse impacts as a result of the proposed water withdrawal and consumption mcreases. PUBLIC NOTICE, INTERVENTIONS, AND COMMENTS
- 13.
On May 7, 2015, Commission staff issued a public notice of the licensee's application for non-project use of project lands and waters, establishing June 7, 2015 as the deadline for providing comments and interventions. By letter dated May 26, 2015, Calpine Corporation filed a motion to intervene. Calpine Corporation owns the York Energy Center which uses and consumes water from the Conowingo reservoir; therefore, Calpine Corporation indicated that it has a direct and substantial interest in the outcome of this proceeding and its intervention and participation is in the public interest. Calpine Corporation did not file any comments on the licensee's proposed action.
- 14.
By letter dated June 2, 2015, the Susquehanna River Boaters Association (SRBA) filed a motion to intervene and a protest; however, the content of the filing does not qualify as a protest of the pertinent application. The SRBA expressed concern with the reservoir elevation, particularly during the May 1 through October 1 recreation season; however, the licensee's application does not propose any modifications to existing reservoir levels requirements. The SRBA also requested that Exelon develop a plan for dredging at the Peach Bottom Marina, to improve accessibility. This issue, also, is not relevant to the proposed water withdrawal as the existing access should not be impacted by this proposal. Under the proposed action, the licensee would still be required to maintain the required reservoir elevations. Any additional consumptive use by Peach Bottom would not affect the reservoir levels as the licensee would manage discharges from Conowingo dam to maintain the required reservoir levels.
- 15.
The SRBA also commented on a number of issues being addressed as a part of the project relicensing. Accordingly those aspects of the SRBA's filing will be addressed under the relicensing process which is currently underway in a separate Commission proceeding. The SRBA indicated that it relies on the use of project waters for recreation and reiterated its interest in the outcome of this proceeding and its intervention and participation in the public interest. On June 18, 2015, Exelon responded to the SRBA's
20150902-3052 FERC PDF (Unofficial) 09 /02/2015 Project No. 405-113 comments. The licensee indicated that many of the SRBA's concerns are topics of ongoing consultation that it intends to address as a part of the relicensing process.
- 16.
By letter dated June 5, 2015, the FWS filed comments pertaining to the protection of fish and wildlife resources. The FWS provided the results of a thermal variance study, which was conducted pursuant to Section 316(a) of the Clean Water Act. The study results confinned that Exelon's requested water withdrawal and consumptive use increases would result in water temperature increases and provided quantification of temperature reductions achievable based on the number of cooling towers utilized. The FWS 's comments also outlined concerns with water temperature impacts to migratory fish. As such, the filing recommended operational rules to minimize and mitigate for water temperature increases.
- 17.
On June 18, 2015, the licensee responded to the FWS' s comments. The licensee's response included the results of a thennal plume modeling study which suggest that the increased water temperature would disseminate locally and not create any type ofthennal barrier to migrating American shad (Alosa sapidissima) or American eels (Anguilla rostrata ). While the extent of the thermal plume depends on inflows and ambient temperature as well as numerous operational factors, the licensee's study predicts that the thermal plume only alters fish migration behaviors, prompting avoidance of the warmed plume, during relatively low flows, less than or equal to 12,500 cfs,6 that occur concurrently with water temperatures between 50 and 60 degrees Fahrenheit. The study concludes that the joint occurrence of these flows and water temperatures with fish migratory seasons is not likely to occur. DISCUSSION
- 18.
Section lO(a)(l) of the Federal Power Act (FPA)7 provides that a licensed project must be: such as in the judgement of the Commission will be best adapted to a comprehensive plan for improving or developing a waterway or waterways for the use or benefit of interstate or foreign commerce, for the improvement and utilization of water-power development, for the adequate protection, mitigation, and enhancement of fish and wildlife (including related spawning grounds and habitat), and for other beneficial public purposes, including irrigation flood control, water supply, and recreational and other purposes. 6 Average flow from the Susquehanna River into the Conowingo reservoir is approximately 40,000 cfs. 7 16 U.S.C. § 803(a)(l).
20150902-3052 FERC PDF (Unofficial ) 09/02/2015 Project No. 405-113 19. Further, section lO(a)(l) of the FPA requires the Commission to ensure that any hydropower project it licenses will be consistent with the optimal utilization of a waterway, taking into account and balancing all the various developmental and environmental values. In addition, section lO(a)(l) standard informs the Commission's actions with respect to a project throughout the term of the license, including its review of requests to use a project's lands and waters for non-project purposes.
- 20.
The considerations specified in section IO(a)(l) are reflected in Article 13 of the project license, a standard article commonly referred to as the joint-use article. Article 13 provides that, in pertinent part: ... on the application of any person, association, corporation, Federal agency, State or municipality, the licensee shall permit such reasonable use of its reservoir or other project properties, including works, lands and water rights, or parts thereof, as may be ordered by the Commission, after notice and opportunity for hearing, in the interests of comprehensive development of the waterway or waterways involved and the conservation and utilization of the water resources of the region for water supply or for the purposes of steam-electric, irrigation, industrial, municipal or similar uses.8
- 21.
The Commission's review of a joint-use application is only to examine whether, and to what extent, the proposed use would adversely affect any other beneficial use of the water, and, if so, whether the benefits of the proposed use outweigh such effects.9 For the reasons discussed below, Commission staff finds that the licensee's request to increase water withdrawal and consumptive use amounts from the Conowingo reservoir complies with Article 13.
- 22.
Commission staffs September 2, 2015 Environmental Assessment (EA) for the proposed action concludes that the increases would not interfere with operations at the Conowingo Hydroelectric Project. The EA finds that the proposed action, with recommended measures, would not result in any significant impacts to geology and soils, water quantity or quality, aquatic resources, threatened or endangered species, or recreation.
- 23.
Section 6.0(B) of the EA includes Commission staffs' recommendations, based on consultation between the licensee and resource agencies and other stakeholders, for 8 19 FERC ~ 61,348 (issued August 14, 1980), at ordering paragraph (D) (citing L-Form 3 in Standard Conditions for Inclusion in Preliminary Permits and Licenses Issued Under Part I of the Federal Power Act, 54 FPC 1792, at 1,821 (1975)). 9 See 74 FERC ~ 61,157 (issued February 16, 1996).
20150902-3052 FERC PDF (Unofficial) 09/02/2015 Project No. 405-113 ensuring that no significant impacts occur as a result of the proposed action. Commission staff recommends that the licensee ( 1) monitor the temperature of waters discharged from Peach Bottom, (2) require Peach Bottom to adhere to cooling tower operating guidelines established by the PDEP, IO and (3) ensure that all necessary state and local permits have been acquired prior implementing the proposed increases. The second and third recommendations would ensure compliance with all other pertinent regulations.
- 24.
The first Commission staff recommendation, to monitor the temperature of waters discharged from Peach Bottom, intends to validate the results of the licensee's thermal plume modeling study and to ensure that migratory fish species are not adversely impacted by the thermal plume, which was a primary concern expressed by the FWS during consultation. Similarly, thermal monitoring of Peach Bottom's discharged water would verify that the PDEP's cooling tower operating guidelines are being employed and that the guidelines provide adequate cooling to the water prior to discharge. In order to accomplish these aims, the licensee should require Peach Bottom to develop and implement a plan to monitor the water temperature of Peach Bottom discharge and the dispersion of the thermal plume for a minimum of five upstream and five downstream fish migration seasons. Five upstream and downstream migration periods should allow for sufficient variation in environmental conditions to detect any significant difference between the model's predictions and actual water temperatures. Accordingly, the first season to implement the temperature monitoring plan should be during the spring of 2016. The plan should include response measures to be implemented ifthe anticipated discharge temperatures are exceeded or if any adverse impacts to migrating fish are observed. In order to keep the Commission apprised of its actions, the licensee should file a copy of Peach Bottom's temperature monitoring plan with the Commission upon receiving it, but no later than March 1, 2016. This should provide sufficient time for Peach Bottom to consult with the resource agencies on the development of the plan and provide it to the licensee. The plan should also include a schedule for reporting the results of the study annually to the Commission for review. Initially, the first report should be due December 31, 2016. IO The PDEP's National Pollutant and Discharge Elimination System Permit (No. PA 0009733) requires Peach Bottom to operate one, two, or three cooling towers between June 15 and August 31 annually, based on average intake temperatures. One tower must be operated continuously from June 15 through August 31. The second tower must commence operation within 48 hours of the average intake temperature reaching or exceeding 83 degrees Fahrenheit (°F), and the third tower must commence operation within 48 hours of the average intake temperature reaching or exceeding 86 °F
20150902-3052 FERC PDF (Unofficial) 09/02/2015 Project No. 405-113 CONCLUSION
- 25.
As modified, the Commission's approval of the licensee's request to increase water withdrawals and consumptive use of water from the Conowingo reservoir, for use in the Peach Bottom cooling towers, will not result in significant adverse impacts to the environment. The proposed non-project use of project lands and waters is consistent with the hydropower project purposes set forth in the project license. The proposed increases would not adversely affect any other existing uses of the waterway, and would therefore be consistent with the waterway's comprehensive development. Therefore, the licensee's application, as modified to incorporate the staff recommendations described in the EA, should be approved.
- 26.
The Commission should reserve the right to require changes to the non-project use of project lands and waters, based on information provided by the licensee or any resource agency, to ensure effective protection of the environmental resources at the Conowingo Hydroelectric Project. The Director orders: (A) Exelon Generation Company's (licensee) May 1, 2015 non-project use of project lands and waters application, to increase water withdrawal and consumptive use permitted for the operation of the Peach Bottom Atomic Power Station (Peach Bottom) to 2,363,620 million gallons per day (mgd) and 49.0 mgd respectively, as modified by paragraphs (B) through (F) below, is approved. (B) The licensee must require Peach Bottom to develop and implement a water temperature monitoring plan to verify that operating under the cooling tower operating guidelines provided by the PDEP adequately reduces discharge temperatures, and that the thermal plume disseminates locally, as predicted by the modeling study results filed by the licensee on June 18, 2015. The plan must, at a minimum: be implemented for at least five upstream and five downstream fish migration seasons; include response measures to be implemented if anticipated discharge temperatures are exceeded or if any adverse impacts to migrating fish are observed; and include a schedule for implementing the plan and reporting the results to the Commission. The licensee must file Peach Bottom's temperature monitoring plan by March 1, 2016 and the first of 5 annual reports must be filed by December 31, 2016. (C) The licensee must require Peach Bottom to adhere to the cooling tower operating guidelines established by the Pennsylvania Department of Environmental Protection (PDEP) to ensure the protection of aquatic resources. (D) The licensee must require Peach Bottom to comply with the terms of the July 23, 2014 Water Quality Certification, issued by the PDEP under section 401(a)(l) of

ENCLOSURE A Peach Bottom Atomic Power Station, Units 2 & 3 Responses to NRC Subsequent License Renewal Environmental Review Requests for Additional Information GROUNDWATER RESOURCES GW-1
Peach Bottom Atomic Power Station NRC Request for Additional Information - Response Sheet Question: RAl-GW-1 Category: Groundwater Resources ER Section: 2.2.3 / 3.5.2 Statement of Question: Sections 2.2.3 and 3.5.2 of the ER provide estimates of the volume of water produced by PBAPS's four active onsite groundwater supply wells as well as the volume of groundwater collected and conveyed by the plant's three drain sumps. Clarify and/or describe the following: a) The operational status of the onsite wells and sumps and their pump capacities. b) If production data is collected for the on-site wells and sumps, provide a summary (by month or other averaging period) of the estimated volume of groundwater withdrawn by the wells or collected in sumps and discharged over the last 5 years (2014-2018 YTD).
Response
Exelon Generation has determined that PBAPS has only three active onsite groundwater supply wells, rather than four. The Hazmat Storage Yard Well is inactive. The current status and capacities of each well discussed in the PBAPS SLR-ER, as well as the current status and capacities of the sumps are described below. a) (1) Salt Storage Area Well (located near the North Substation in Salt Storage Area) i) This well is owned by Exelon Generation Company/PBAPS. ii) This well of unknown depth includes an 11 gpm well pump. It is used for washing of vehicles. iii) Typical usage, which occurs on an as-needed basis, is estimated to be less than 100 gallons per week during the winter months for washing vehicles following salting operations. Usage could possibly be up to 500 gallons per week during periods of icing when there is a high amount of salting activity ongoing. The well typically has very little to no use during the warm weather months. iv) No production volume data are collected for this well. v) Wastewater runs off and is absorbed by the surrounding soil. a) (2) South Substation Well (located within the PECO South Substation) i) This well is owned by Exelon Generation Company/PBAPS, but PECO maintains it under the substation property lease. ii) This 300-foot deep well includes a 1 to 2 gpm well pump. iii) This well is used intermittently to provide non-potable water in the unmanned substation control house restroom, which is available to workers who occasionally visit the South Substation. iv) No production volume data are collected for this well. v) Wastewater from the restroom is routed to a nearby septic tank. a) (3) North Substation Well (located within the PECO North Substation) i) This well is owned by Exelon Generation Company/PBAPS, but PECO maintains it under the substation property lease. ii) This 250-foot deep well includes a well pump of unknown capacity, but is believed to be similar to the South Substation well (thus its capacity is likely less than 5 gpm, possibly 1 gpm to 2 gpm). GW-2
iii) This well is used intermittently to provide non-potable water in the unmanned substation control house restroom, which is available to workers who occasionally visit the North Substation. iv) No production volume data are collected for this well. v) Wastewater from the restroom is routed to a nearby septic tank. a) (4) Hazmat Storage Yard Well (located at Northern end of the PBAPS Upper Parking Lot) i) This well is owned by Exelon Generation Company/PBAPS. ii) This 300-foot deep well includes a 6 gpm well pump. iii) This well is inactive. The well pump was electrically de-energized an undetermined number of years ago, and the well is not currently used. There are no plans to use the well in the future. It was previously used for rinsing equipment and possibly for hand washing associated with an area designated for storage of hazardous materials, which has since been moved to another location on the PBAPS site. iv) No production volume data were ever collected for this well. a) (5) Yard Drain Sumps Each reactor building and the low-level radioactive waste storage building has a sump that collects groundwater and discharges it to the river or to the discharge canal in accordance with NPDES Permit No. PA0009733. i) The Unit 2 Yard Drain Sump and the Unit 3 Yard Drain Sump contribute a combined maximum flow to Outfall 004 of 72,000 gpd. ii) In addition to flow from the Unit 2 and Unit 3 Yard Drain Sumps, Outfall 004 receives blowdown from the Auxiliary Boilers and storm water runoff. iii) The estimated maximum contribution to Outfall 901 from the Low-Level Rad Waste Storage Facility yard drain sump tank is 30,000 gpd, which discharges intermittently into the Conowingo Pond in combination with storm water runoff. iv) No Yard Drain Sump discharges are metered. b) Total flow volumes for Outfalls 004 and 901, which include but are not limited to the yard drain sump discharges, as calculated and reported on NPDES Discharge Monitoring Reports during 2014 through September 2018, are summarized in the attached Table RAl-GW-1.

Peach Bottom Atomic Power Station NRC Request for Additional Information - Response Sheet Question: RAl-GW-3 Category: Groundwater Resources ER Section: 2.2.5.1 Statement of Question: Section 2.2.5.1 of the ER, in part, describes the operation of the plant's liquid radwaste system including the discharge pipeline for conveying monitored liquid radwaste effluent to the discharge canal. Summarize the average volume and frequency of discharge and identify the presets for flow and radiation for automatic shut-off. Also, briefly describe any major modifications to the pipeline since initial license renewal.
Response
The PBAPS UFSAR (Rev. 26), Section 9.2.4.3 explains that, after filtration, aqueous liquid radwaste from Units 2 and 3 can be discharged to the environment via the environmental discharge subsystem from three sources in the liquid radwaste system: (1) the floor drain sample tank (21,000 gallons}, (2) either of the two equipment drain waste sample tanks (25,000 gallons each), and (3) either of the laundry drain tanks (1,000 gallons each). The following information is derived from the UFSAR. Discharges are made on a batch basis, and each release is controlled based on knowledge of the radioactivity concentration and volume of the material in the tank from which the discharge originates. The radioactivity concentration is obtained by analyzing a sample from the sample tank obtained after recirculation for gross radioactivity and gamma isotopic. The rate of release of the liquid waste to the discharge canal which produces a concentration in the canal (after dilution with a known flow of circulating water) equal to the allowable concentration limit is then calculated. A rate of release below the calculated maximum allowable rate is then selected and used for the specific batch of liquid waste to be discharged to the environment. Radwaste liquids can be pumped to the discharge canal only through a single line at a limited rate. Two discharge pumps are provided to release wastes from the floor drain subsystem, one rated at 65 gpm for low flows, and the other rated at 280 gpm for higher discharge flow rates. Two pumps, each rated at 25 gpm, will discharge wastes from the laundry drain subsystem, and two pumps rated at 280 gpm can discharge liquid wastes from the equipment drain subsystem, although it is normally planned to reuse this water. To control these releases, the single discharge line is provided with two flow meters in parallel (one for high flow and one for low), a radiation monitor, and a downstream shut-off valve. The shut-off valve is closed automatically if preset flow or radiation limits are exceeded. When the proper release rate has been determined for a given batch of liquid radwaste, the desired flow rate is set on one of the two flow controllers, and the high radiation monitor alarm and trip point is correspondingly set such that the radioactivity concentration after dilution will be within allowable limits. The downstream automatic shut-off valve is then opened to release the liquid radwaste to the discharge canal. During the release, the downstream radiation monitor in the discharge line continuously measures, indicates, and records the radioactivity level in the liquid being discharged. The liquid waste discharge flow rate is also indicated and recorded to ensure that proper dilution of discharged radioactive waste has been attained. A syphon breaker is provided in the waste effluent line to protect against accidental and uncontrolled release from the sample tanks. GW-7
A high radioactivity concentration or high discharge flow rate in the discharge line actuates an alarm, if preset maximum limits are exceeded. An interlock is provided to prevent the discharge of liquid waste to Conowingo Pond unless a minimum of one circulating water pump rated at 250,000 gpm is operating to provide proper dilution with condenser cooling water. (Total circulating water flow for both Units 2 and 3 is 1,500,000 gpm.) If either the preset high activity level or the preset high flow rate is exceeded or if the circulating water flow stops, the downstream isolation valve automatically closes to terminate the release of liquid radwaste, and an alarm sounds in both the main and radwaste control rooms. A continuous composite sample of condenser circulating water from the discharge canal is collected from a point downstream of the mixing zone where the radwaste effluent is discharged into the canal. This serves as a final audit for the total radioactivity being released to the Conowingo Pond. Major Modifications Since Initial License Renewal During 2014, the portion of the radwaste discharge pipe between the turbine building and the point of discharge, which is in the discharge canal just south of the former "D" cooling tower, was replaced. The project consisted of replacing the 4-inch carbon steel pipe with a 5-inch single wall high-density polyethylene (HOPE) pipe. The replacement pipe follows the path of the previous carbon steel pipe until it extends past the security fence where it diverts into the discharge canal. The HOPE is anchored to the bottom of the discharge canal using concrete foundations/ballasts and terminates at the same discharge point as did the carbon steel pipe.

September 2016 - Fecal Coliform -- A fitting on the suction side of the 'B' Sodium Hypochlorite (NaOCI) Injection Pump at the Sewage Treatment Plant (STP) had a slight crack, resulting in the pump delivering an inadequate amount of NaOCI to the STP process. This low NaOCI level led to a high Fecal Coliform concentration (2000 CFU/100 ml), which is above the NPDES limit of 1000 CFU/100 ml. Verbal notification to PADEP occurred on 9/19/2016 when the analysis result was received, and written notification to the PADEP was completed on 9/24/2016 as required. The cracked fitting on the suction side of 'B' Sodium Hypochlorite Injection Pump was repaired. (Reference 3)

The 8005 result was <6.0 ppm. This result was communicated to the NPDES permit inspector on 819/16. Also communcated to the inspector is the C80D result should be less than or equal to 8005 due to the fact 8005 measures the oxidation of carbons and possibly nitrogenous compounds present and C80D only measures oxidation of carbons.

Peach Bottom Atomic Power Station NRC Request for Additional Information - Response Sheet Question: RAl-GW-5 Category: Groundwater Resources ER Section: Not Applicable Statement of Question: Provide copies of the annual water withdrawal reports (for 2014-2017) submitted to the Susquehanna River Basin Commission as required under Docket 20061209-1, Standard Condition 4. Clarify whether Exelon has registered and reports all on-site surface water and groundwater withdrawals to the Pennsylvania Department of Environmental Protection in accordance with 25 PA Code 110.201 and as specified in SRBC Docket Standard Condition 8. If so, please provide copies of supporting documentation.
Response
Fourth quarter monitoring reports submitted to the Susquehanna River Basin Commission (SRBC) for 2014 through 2017 are incorporated into this response sheet (References 1 through 4). These fourth quarter reports include daily surface water withdrawal amounts taken from Conowingo Pond by PBAPS for all quarters of each year and were submitted to the SRBC as required by Standard Condition 4 in Docket 20061209-1. As specified in Standard Condition 8 in SRBC Docket 20061209-1, PBAPS has registered its use of all water sources described in the docket with the PADEP in accordance with 25 PA Code §§110.201 and 110.203. Also, in accordance with 25 PA Code 110, Subpart C, PBAPS reports amounts of water withdrawal and use to PADEP annually. PADEP's enterprise Water Use Data System (WUDS) database stores the data collected from the registration and water use reports. Evidence that PBAPS is registered and reports of data submitted to PADEP are available at https://www.dep.pa.gov/DataandTools/Reports/Pages/Water.aspx where the PBAPS WUDS Primary Facility ID number is 27592. No groundwater withdrawal use amounts are currently included in reports to either SRBC or PADEP. As Exelon Generation's response to the NRC's request for additional information RAl-GW-1 explains, two of the three active water supply wells at PBAPS have a pumping capacity of less than 5 gpm, and each is used only intermittently to provide water for a restroom at an unmanned electrical substation. Wastewater from the restroom at each substation is routed to a nearby septic tank. The third active water supply well has an 11-gpm pump and is used mostly during winter months for washing vehicles. During periods of winter weather requiring road and sidewalk salting, the estimated maximum use rate is 500 gallons per week, which runs off and is absorbed by the surrounding soil. Thus, the three active PBAPS water supply wells result in de minimis amounts of groundwater withdrawal.

Executive Summary This Hydrogeologic Investigation Report (HIR) documents the results of hydrogeologic investigations by GHD (formerly Conestoga-Rovers & Associates [CRA]) and Exelon Nuclear Generation (Exelon) from October 2006 through December 2017 pertaining to the Peach Bottom Generating Station in Delta, Pennsylvania (Peach Bottom or Station). GHD has prepared this updated HIR for Exelon to determine whether groundwater at and near its nuclear power generating facilities has been adversely impacted by any releases of radionuclides since 2006. The original HIR document was prepared in September 2006 by GHD. In accordance with the Nuclear Energy Institute (NEI) Guidance developed in 2007, Industry Ground Water Protection Initiative - Final Guidance Document (July 2007), (NEI 07 07), GHD has reviewed the activities and the groundwater conditions at the Station from October 2006 through December 2017. This report focuses on changes to the following topics since submittal of the most recent HIR submittal (CRA, 2012): Hydrogeologic Studies Areas for Further Evaluation Subsurface Disturbances and Major Construction Changes in On Station and Off Station Groundwater Supplies Documented Spills or Leaks (Reported to Agencies) Status of Remedial Actions Hydrogeologic Studies The following summarizes the hydrogeologic conditions at the Station: Tritiated water is not migrating off the Station property at detectable concentrations. Gamma emitting radionuclides, associated with licensed plant operations, were not detected at concentrations greater than their respective Lower Limits of Detection (LLDs) in any of the groundwater or surface water samples obtained and analyzed from the Radiological Groundwater Protection Program (RGPP) sampling event. There is no current risk from exposure to radionuclides associated with licensed plant operations through any of the identified potential exposure pathways. Areas for Further Evaluation (AFE) The following AFE was identified in the 2012 HIR. AFE-Peach Bottom Unit 2 and Unit 3 Reactor and Turbine Building Areas Based on a review of the data from May 2012 through December 2017, A FE-Peach Bottom Unit 2 and Unit 3 Reactor and Turbine Building Areas is retained as an AFE.

t ' Subsurface Disturbances and Major Construction There were three subsurface disturbances from May 2012 through May 2017: (1) The Unit 3 Adjustable Speed Drive Building (west of the Torus Dewatering Tank and Unit 3 Condensate Storage Tank moats; (2) The FLEX building (southwest of the Owner Controlled Area checkpoint); and (3) excavations/dewatering northwest of the Administration Building for buried pipe inspections. Changes in On Station and Off Station Groundwater Supplies There were no significant changes to on-Station or off-Station groundwater supplies. Documented Spills or Leaks (Reported to Agencies) On January 24, 2015, there was a there was a release of approximately 40 gallons of hydraulic fluid from an elevator. The spill was deemed non reportable following evaluation and Discussion with Pennsylvania Department of Environmental Protection. On April 15, 2015, a leak in the Unit 3 Moisture Separator Area resulted in an increase in tritium activity in monitoring wells adjacent to the Unit 3 Turbine Building. The leak was reported to the NRC, Commonwealth of Pennsylvania, and State of Maryland on May 15, 2015. The floor and utility conduit penetrations in the Moisture Separator Room were sealed, and tritium concentrations in downgradient monitoring wells subsequently decreased. Status of Remedial Actions No remedial actions are ongoing at the Station. GHD I Hydrogeologic Investigation Report 111137316 (1) I Page ii

Introduction GHD (formerly Conestoga-Rovers & Associates [CRA]), on behalf of Exelon Generation Company, LLC (Exelon), has prepared this updated Hydrogeologic Investigation Report (HIR) as part of the continued and ongoing, industry-wide effort to identify and report groundwater conditions within the boundaries of nuclear power plants. The objective of this report is to document groundwater and surface water investigations completed since 2012 at Exelon's Peach Bottom Atomic Power Station in Delta, Pennsylvania (Station). The groundwater and surface water investigations were completed on Exelon owned land associated within the Protected Area (PA) and within the Owner Controlled Area (OCA). Figure 1.1 presents a Station Location Map. The Station is defined as all property, structures, systems, and components owned and operated by Exelon at 1848 Lay Road in Delta, Pennsylvania, Peach Bottom Township, York County, and Drumore and Fulton Townships, Lancaster County, Pennsylvania. The approximate property boundaries are depicted on Figure 1.2. The Nuclear Energy Institute (NEI), an industry stakeholder group, has prepared guidance to identify actions to improve the management and response to instances where the inadvertent release of radioactive substances may result in detectable levels of radioactive materials in subsurface soils and water. These actions are described in NEl's Industry Ground Water Protection Initiative - Final Guidance Document (July 2007) (NE/ 07 07). As Exelon proactively developed and implemented its program prior to the development of NEl's initiative, the recommendations and methods discussed in NEl's Guidance Document have been considered in the Station's on going groundwater protection initiative (GPI). This Guidance was considered during the preparation of this HIR. The Electric Power Research Institute, Inc. (EPRI) conducts research and development relating to the generation, delivery, and use of electricity for the benefit of the public. EPRI prepared a guidance document entitled Groundwater Protection Guidelines for Nuclear Power Plants (November 2007) to provide the nuclear power industry with guidelines for the implementation of groundwater protection programs at nuclear power plants. EPRl's Guidance Document has been considered in the Station's on-going GPI. This Guidance was considered during the preparation of this HIR. In 2006, CRA prepared a Hydrogeologic Investigation Work Plan (Work Plan) to assist in the development of a voluntary groundwater monitoring program with an emphasis on the early detection of radionuclides at the Station. This program is known as the Radiological Groundwater Protection Program (RGPP) and follows an industry-wide proactive effort that focuses on groundwater monitoring within the boundaries of the power plant. The NEI, an industry stakeholder group, has prepared guidance to identify actions to improve utilities' management and response to instances where the inadvertent release of radioactive substances may result in low but detectable levels of Station-related materials in subsurface soils and water. These actions are described in detail in NEl's Industry Ground Water Protection Initiative - Final Guidance Document (July 2007). As Exelon proactively developed and implemented its program prior to the development of NEl's initiative, the recommendations and methods discussed in the NEI Guidance Document were GHD I Hydrogeologic Investigation Report 111137316 (1) I Page 1
considered and incorporated, as appropriate, in the Station's on-going groundwater protection program. In 2006, Exelon completed a baseline hydrogeologic investigation. Tritium was not detected at concentrations greater than the United States Environmental Protection Agency (USEPA) drinking water standard of 20,000 picocuries per liter (pCi/L) in any of the groundwater or surface water samples. The results of the baseline HIR were documented in a report entitled Hydrogeologic Investigation Report (CRA, 2006b). In 2011, a NEI 07-07 Update Questionnaire was issued to the Station and completed by knowledgeable Station personnel. Station conditions were summarized and reported in the "NEI 07 07 Update Hydrogeologic Investigation Summary Report" in May 2011 (CRA, 2011b). In May 2012, CRA prepared the five-year update of the HIR (CRA, 2012). Since that time, a number of changes in conditions have occurred at the Station and additional hydrogeologic investigations have been completed up to the date of this report. In accordance with NEI 07 07, GHD has reviewed the activities and the groundwater conditions at the Station from May 2012 through December 2017. This review was in accordance with Section 3.0 Program Oversight, Objectives 3.1 and 3.2 of the NEI 07 07 guidance and it addressed the following major conditions or activities at the Station since 2012: Hydrogeologic studies Areas for Further Evaluation Subsurface disturbances and major construction Changes in on-Station and off-Station groundwater supplies Documented spills or leaks (reported to agencies) Status of remedial actions In 2017, an NEI 07-07 Update Questionnaire was issued to the Station and completed by knowledgeable Station representatives. A copy of the completed Questionnaire is included as Appendix A. GHD used the information gathered in the Questionnaire during the preparation of this HIR. 1.1 Supporting Documents This updated HIR has been prepared in general accordance with the NEI 07-07 Industry Groundwater Protection Initiative.

Station Description The following section presents a general summary of the Station location and definition, overview of Station operations, surrounding land use, and an overview of regional and Station-specific topography, surface water features, geology, hydrogeology, and groundwater flow conditions. An overview of the groundwater use in the area is also presented. 1.2 Station Location The Station is at 1848 Lay Road, Delta, Pennsylvania (see Figure 1.1 ). The Station property consists of 620 acres. The Station is co-owned by Exelon and Public Service and Gas of New Jersey. Figure 1.2 presents the Station property and includes key Station features. 1.3 Overview Of Cooling Water Operations Operations at the Station began in June 1967 with Unit 1, a 40-megawatt experimental high-temperature, helium cooled, graphite moderated reactor. Unit 1 is adjacent to Rock Run Creek. Unit 1 which operated under NRC Operating License DRP-12, was permanently shut down on October 31, 1974 and is now maintained in the U.S. Nuclear Regulatory Commission's (NRC's) decommissioning method known as SAFSTOR (safe storage of components of the nuclear power plant). Units 2 and 3 were built between 1968 and 1973 and entered commercial service on July 5, 1974 and December 23, 1974, respectively (Exelon, 2017a). The Station's generating system consists of two General Electric boiling water reactors (Units 2 and 3), two steam turbine generators, heat-dissipation systems, and associated auxiliary facilities and engineering safeguards. Units 2 and 3 are capable of generating 1,366 gross megawatts electric each. The Station operates under NRC Operating Licenses DPR-44 and DPR-56 (USNRC, 2003a). Non-contact cooling water is withdrawn from the Conowingo Reservoir. Water withdrawn from the Conowingo Reservoir passes through a series of intake structures before it is circulated through two GHD I Hydrogeologic Investigation Report I 11137316 (1) I Page 3
main condenser units (one for each unit). From the condensers, the cooling water is returned through a series of discharge structures and is discharged to the Conowingo Reservoir. Exelon has the ability to use three mechanical draft cooling towers, which have the capacity to cool approximately 60 percent of the circulating cooling water flow. During normal plant operations, circulating cooling water moves through the plant from the intake structure to the discharge structure in approximately 88 minutes. When the three cooling towers are in operation, the travel time is approximately 109 minutes (USNRC, 2003b). The Conowingo Reservoir, east of the Station, receives discharge from the Station outfalls via the Discharge Canal under the Station's National Pollution Discharge Elimination System (NPDES) permit (permit# PA0009733) and the NRC Operating Licenses DPR-44 and DPR-56. 1.4 Surrounding Land Use Land use in the area is predominantly rural and is characterized by farms and forests. Properties immediately adjacent to the Station consist of agricultural land to the south; undeveloped land, farms, and residences to the west; residences to the northwest; a picnic area and public boat dock to the north; and the Conowingo Reservoir to the immediate east. Based on aerial photos (Google Earth Pro, 2016), the population density immediately adjacent (within a one-mile radius) to the Station remains low. 1.5 Station Setting The following sections present a summary of the topography, surface water features, geology, hydrogeology, and groundwater flow conditions in the region surrounding the Station. 1.5.1 Topography and Surface Water Features The Station lies within the Piedmont Upland Section of the Piedmont Physiographic Province of the Appalachian Highlands (Low and Hippe, 2002). The northeast-southwest trending Piedmont Province is an eroded plateau of low relief and rolling topography. Dendritic drainage patterns are prominent in the Piedmont Upland Section, which is characterized by broad, rounded to flat-topped hills and shallow valleys, with moderate to steep slopes. Near the Susquehanna River, steeper slopes and deeper, narrower valleys are more common (Low and Hippe, 2002). Surface elevations in the Upper Piedmont Section generally range from 100 to 300 feet above mean sea level (AMSL). The general topography of the Station and surrounding area (USGS, 1995) is shown on Figure 1.1. The original topography was characterized by rugged, heavily wooded terrain prior to Station development. Original elevations ranged from about 400 feet AMSL in the western portion of the Station property to about 110 feet AMSL near the Conowingo Reservoir. The ground surface slopes steeply to the east toward the Reservoir. The area immediately to the west of the Station is a rock cliff that was created when a portion of the original hillside was cut away to construct the Station. The hillside rises to an elevation of nearly 300 feet above the Conowingo Reservoir. The main stack and the north switchyard are on this hilltop. The post-construction ground surface elevation at the base of the excavated hillside is GHD I Hydrogeologic Investigation Report I 11137316 (1) I Page 4
r~1 § approximately 135 feet Conowingo Datum (G.D.). 1 The finished grade of the plant has been established at an elevation of 116 feet G.D., which is approximately 3 feet above the estimated 1936 flood level. Excavation into bedrock for the foundations of the Turbine and Reactor Buildings extended to 80 feet G.D. The base level of the Station immediately east of the Turbine Building is approximately 116 feet G.D. From this area, the Station slopes gently downward to the east to an elevation of approximately 110 feet G.D. (near well MW-PB-6) adjacent to the Conowingo Reservoir. The Conowingo Reservoir is immediately east of the Station. The normal reservoir elevation is between 104 and 109.25 feet G.D. The reservoir is used for non-contact cooling water and potable drinking water at the Station. The Conowingo Reservoir is also a public water supply source for the City of Baltimore, Harford County (Maryland), and the Chester (Pennsylvania) Water Authority (URS, 2012). The reservoir receives discharge from the Station outfalls via the Discharge Canal under the Station's NPDES permit. The canal is approximately 5,000 feet in length to provide tempering for approved discharges. The Station maintains the flow in the canal at an elevation a few inches above the Conowingo Reservoir and at a sufficient rate to ensure discharge. Surficial drainage within the Station is directed to Rock Run Creek, a perennial stream south of Unit 1 that flows in an easterly direction into the Discharge Canal. The watershed of Rock Run Creek is approximately four square miles. 1.5.2 Geology The following sections present the regional and Station geology. Regional Geology Figure 2.1 presents a regional geologic map for the Station area. The region is underlain by metamorphosed sedimentary and crystalline rocks of Paleozoic and Precambrian age (approximately 435 to 700 million years ago), which are known collectively as the Glenarm Series_ For this HIR, the Group level nomenclature (e.g., Glenarm Series) presented on the 1980 edition of the Pennsylvania State Geologic Map and used in previous Station reports is retained for consistency. The metamorphosed sedimentary rocks include, in order of decreasing age, the Wissahickon and Peters Creek Schist, Cardiff Conglomerate, and Peach Bottom Slate. The rocks are relatively resistant to erosion and support an uneven hilly surface (Schultz, 1999). The soils in the region belong to the Manor-Glenelg Soil Association or the Cardiff-Whiteford Association. The soils near the Station belong to the Manor-Glenelg Association. These soils are described as shallow and moderately deep, mostly moderately steep to very steep soils underlain by schist or phyllite. Soils south of Rock Run are mostly in the Cardiff-Whiteford Association and are described as shallow and moderately deep soils underlain by slate, hard shale, or hard phyllite (U.S. Department of Agriculture, 2006). Station Geology In general, the Station stratigraphy is comprised of, in descending order: Conowingo Datum is a local elevation reference; it corresponds to 0.702 feet AMSL.

Fill Unconsolidated Deposits Weathered Bedrock (Peters Creek Schist) Competent Bedrock (Peters Creek Schist) The following provides a description of the subsurface units. Fill and Unconsolidated Deposits The fill includes native unconsolidated deposits that were re-located during Station construction activities and re-distributed schist fragments resulting from bedrock excavation activities. In addition, silt, sand, and gravel from off the Station property were used as fill. Some native undisturbed soils underlie the Station outside the construction area, and are up to 15 feet thick. These soils are described as consisting of compact silty sand and sandy silt containing gravel and weathered rock fragments (up to boulder size). Bedrock - Peters Creek Formation The Peters Creek Formation is a greenish-gray to white chlorite schist interbedded with seams and bands of quartzite that range up to 6 feet in thickness. In general, bedrock is encountered at depths ranging from zero to 30 feet below grade. Near the Station, the Peters Creek Formation has a southwest-northeast strike and dips northwest 60 to 70 degrees. The formation is characterized by tight isoclinal folds, thin lenticular bedding, a well developed schistosity, and many discontinuous joint sets. The upper part of the Peters Creek Formation has been altered by weathering. The zones of severe weathering are generally limited to thicknesses of 25 feet or less, although excavation in the western portion of the construction area encountered highly weathered rock to depths in excess of 65 feet below the original rock surface. A few seams within the bedrock exhibit a high degree of weathering to known depths of up to 200 feet. These weathered zones are relatively thin and generally parallel the schistosity of the rock. The relatively fresh rock surface was encountered at depths ranging from about 15 feet below original grade, near the Conowingo Reservoir, to greater than 80 feet below grade in the higher western portion of the construction area. 1.5.3 Hydrogeology The groundwater in the overburden soils and fill deposits occurs under unconfined conditions and is referred to as the water table or shallow aquifer. Water table elevations at the Station typically range from an elevation of 115 feet C.D. at the western end (western end of the Turbine Building), to 108 feet C.D. at the eastern end. At the interface of the western end of the Station and the rock cliff face, the shallow aquifer is not mapped since there are no overburden materials present. Overburden material (including fill) thicken eastward toward the Conowingo Reservoir. Groundwater elevations observed in the bedrock aquifer typically range from 116 feet C.D. at the western end to 110 feet C.D. at the eastern end. The bedrock underlying the Station (Peters Creek Schist) has relatively low primary porosity. In consolidated bedrock with low primary porosity, such as the Peters Creek Schist, groundwater is GHD I Hydrogeologic Investigation Report 111137316 (1) I Page 6
stored in and transmitted through networks of cleavage planes, joints, fractures, and faults (Low and Hippe, 2002). The Peters Creek Schist typically has low yields capable of supporting domestic use (Low and Hippe, 2002). In the Peters Creek Schist, the dominant fracture system is along bedding planes with subvertical joints along strike (PBAPS, 2005). When stressed {by pumping), groundwater flow is predominantly along strike and dip. Due to the dipping nature of the beds, resulting cones of depression appear to have an elongated shape parallel to strike. The USGS reported the median yield of 29 domestic supply wells completed in the Peters Creek Schist as 9 gallons per minute (gpm), with minimum and maximum values of 0.2 and 60 gpm, respectively (Low and Hippe, 2002). Groundwater seeps exist at several locations along the rock face to the west of the Reactor Buildings. A subsurface porous drain dewatering system (built during Station construction) was installed immediately west of Unit 2 and Unit 3 Reactor Buildings (Figure 2.2). The purpose of the dewatering system is to prevent groundwater buildup from the seeps and infiltration from precipitation. The groundwater that enters the system is directed to one of two sumps (north [U3 Yard Drain Sump] and south [U2 Yard Drain Sump]), which pump the water to the Station's storm drain system. The water is ultimately discharged to the Discharge Canal or Conowingo Reservoir under the Station's NPDES permit. On September 8, 1995, the drain system was deactivated. Groundwater intrusion into Station buildings (primarily U2 and U3 Turbine Buildings) occurred from 1995 until the system was reactivated in May 2006. The drain system has been active since May 2006. The pumps in the north and south sumps are regulated by automatic floats; flow rates and discharge volumes are not recorded. 1.6 Area Groundwater Use Water supply wells are present at and near the Station. Groundwater withdrawals from these wells are primarily from the bedrock aquifer with only one well completed in the overburden. In 2006, CRA performed a comprehensive private well survey/inventory within one mile of the Station. The results of the search are presented in the 2006 HIR. In 2012 and 2017, CRA/GHD performed a comprehensive public and private water well survey/inventory within one mile of the Station. The results of the searches are presented in Appendix B. A summary of the results of these searches is presented below. On-Station Groundwater Use The Station currently obtains its drinking water from the Conowingo Reservoir via the Intake Pond. Three former potable water supply wells existed at the Station; two at the former Information Center, and one at the former Presidential Utility Building (PUB). All three wells were constructed into the bedrock as open-rock boreholes. The total depths of the two Information Center wells were 100 and 240 feet below ground surface (bgs). The total depth of the PUB well was 280 feet bgs. The Station properly abandoned the three potable water supply wells by filling them with concrete. Figure 2.3 presents a map of the existing non-potable water supply wells. The general locations of the four non-potable water supply wells are: GHD I Hydrogeologic Investigation Report 111137316 (1) I Page 7
North Substation; South Substation; Hazmat Storage Yard; and Salt Washdown Area. The four wells above were sampled semi-annually through May 2010 as part of the RGPP. Well construction information is available for only two of the four wells (South Substation and Hazmat Storage Yard) and no survey data are available for any of the supply wells. The South Substation and Hazmat Storage Yard wells were constructed in bedrock to depths of 300 and 200 feet, respectively. The South Substation well produces approximately 2 gpm and is used for toilet flushing, while the Hazmat Storage Yard well produces approximately 6 gpm and is used to rinse equipment. Off-Station Groundwater Use In 2006, 2012, and 2017, GHD performed comprehensive private well surveys/inventories within a one-mile radius of the Station. The results of the 2017 search are included in Appendix 8. In May 2017, GHD conducted comprehensive searches of the Pennsylvania Groundwater Information System (PaGWIS) database to identify water supply wells within a one-mile radius of the Station. As a conservative measure, the database searches were conducted using coordinates from the central portion of the entire Station property and not the center of the major Station structures, due to the size and irregular shape of the property. A review of the database table reveals the following type and associated number of off-Station wells within the one-mile radius of the Station: Domestic= 11 wells (79%) Irrigation = 1 well (7%) Stock= 1 well (7%) Test (unused) = 1 well (7%) Total = 14 wells The updated water well database search indicated one new water well off Station property within a one-mile radius of the Station; the well is described as a "test" well (above) and its use is listed as "unused." In summary, there were no significant changes in off-Station groundwater use from 2012 to 2017.

Areas for Further Evaluation This section discusses the Areas for Further Evaluation (AFEs). The AFEs were originally identified as areas at the Station that warranted further evaluation during the 2006 hydrogeologic investigation. At that time, Exelon considered all Station operations in assessing groundwater quality at the Station. GHD I Hydrogeologic Investigation Report J 11137316 (1) I Page 8
The identification of AFEs in 2006 involved the following components: Station inspections in March 2006; Interviews with Station personnel; Evaluation of Station systems; Investigation of confirmed and unconfirmed releases of radionuclides; and Review of previous Station investigations. The information collected from these components was combined with information obtained with CRA's 2006 review of hydrogeologic conditions at the Station to identify those areas where groundwater potentially could be impacted from operations at the Station. CRA then conducted an investigation in 2006 to determine whether any confirmed or potential releases or any other release of radionuclides adversely affected groundwater. This entailed evaluating whether existing Station groundwater monitoring systems were sufficient to assess the groundwater quality at the AFEs. If the systems were not sufficient to adequately investigate groundwater quality associated with any AFE, monitoring wells were installed by CRA. The following AFE's were identified in the 2006 HIR: AFE-Peach Bottom Unit 3 Condensate Storage Tank and Torus Dewatering Tank Area AFE-Peach Bottom Unit 2 and Unit 3 Reactor and Turbine Building Areas AFE-Peach Bottom Main Stack Sump Based on a review of the results of the 2006 HIR, the information gathered during the October 2006 to December 2017 time period, and the responses provided by the Station in the NEI 07-07 Questionnaire in 2017, GHD evaluated tritium results and changes in Station conditions that affect groundwater, as stipulated in the NEI 07-07 guidance. AFE-1 and AFE-3 are no longer considered AFEs. AFE-2 remains as an AFE and is depicted on Figure 3.1, and discussed in further detail in Section 3.4. The following presents a summary of the current evaluation of systems, releases, monitoring results, investigations, and new construction. 2.1 Systems Evaluations In 2006, Exelon launched an initiative to systematically assess the structures, systems, and components (SSCs) that store, use, or convey potentially radioactively contaminated liquids. Engineering drawings depicting each of these systems were developed and provided to CRA for review. The Station originally identified a total of 21 systems that contain, or could potentially contain, radioactively contaminated liquids. The SSCs identified are depicted on Figure 3.1. The Station periodically reviews the SSCs. No new SSCs were identified as a concern in 2012. In 2008, the Station developed a Failure Mode Complex Troubleshooting (FMCT) program to identify SSCs potentially contributing to the elevated tritium concentrations identified in monitoring well MW-PB-4. As a result, several SSCs within the Unit 3 Turbine Building (AFE-2), upgradient of MW-PB-4, were identified and selected for further evaluation. These SSCs are discussed further in Section 3.4. GHD I Hydrogeo\\ogic Investigation Report I 11137316 (1) I Page 9
2.2 Known Releases Pre-2006 CRA reviewed information concerning confirmed or potential historical releases of radionuclides at the Station, including reports and documents previously prepared by Exelon and compiled for CRA's review. CRA evaluated this information in identifying the AFEs. Any historical releases identified during the course of this assessment that may have a current impact on Station conditions are further discussed in Section 3.4. 2006-2017 CRA/GHD reviewed the activities at the Station during the period from December 2012 to October 2017 and the results of the Stations response to the NEI 07-07 Update Questionnaire regarding potential or documented releases of tritium and other radionuclides. During this period of time, three releases to the subsurface were identified that had the potential to have an impact on Station groundwater conditions. The releases are described below. Unit 3 Condensate Storage Tank Moat On June 17, 2009, a valve leak was identified in the Unit 3 Condensate Storage Tank (CST) Moat (AFE-1 ). The valve was on a portion of piping that penetrated the moat floor and condensate leaked into the subsurface. Since the valve and piping were covered by insulation, the duration and volume of the leak is unknown. The valve packing was adjusted and the leak was stopped on June 18, 2009. At the time, the leak was deemed a potential source of elevated tritium concentrations identified in monitoring well MW-PB-4. Concentrations of tritium greater than 2,000 pCi/L were first identified in MW-PB-4 in November 2007. Courtesy notifications were made to the Pennsylvania Bureau of Radiation and the NRG. Analytical results from three groundwater samples (MW-PB-24, MW-PB-25, and MW-PB-26) collected on July 8, 2009 indicated tritium concentrations greater than the NEI 07-07 voluntary reporting threshold of 20,000 pCi/L. The highest concentration of tritium (127,252 pCi/L) was from a confirmation sample collected at monitoring well MW-PB-26. On July 31, 2009, Exelon Nuclear submitted a voluntary, special report to the NRG regarding tritium in groundwater. In February 2017, an increased tritium activity of 1,020 pCi/L was detected in the Unit 3 Yard Drain. The source of the increased concentration was found to be degradation of the Unit 3 CST Moat. The Unit 3 CST Moat was cleaned and sealed, and tritium concentrations subsequently decreased in the Unit 3 Yard Drain. Unit 2 Turbine Building On September 12, 2010, an estimated 11 gallons of condensate impacted soil at the south end of the Unit 2 Turbine Building. The impacted soil was removed and based on groundwater data from downgradient monitoring wells the leak did not affect groundwater. Unit 3 Turbine Building Moisture Separator Room Area On April 13, 2015, an inadvertent release of licensed material occurred inside the Moisture Separator Room of the Unit 3 Turbine Building. Pooled condensate water (-3 million pCi/L) GHD I Hydrogeologic Investigation Report I 11137316 (1) I Page 10
cm11 f id migrated though seams around floor drains and entered the subsurface. Increased tritium was identified in the monitoring wells east of the Unit 3 Turbine Building. The Station mitigated this pathway by sealing the floor and utility conduit penetrations in the Moisture Separator Room. Tritium concentrations in downgradient monitoring wells subsequently decreased. 2.3 Ongoing Monitoring This section summarizes ongoing monitoring programs at the Station including the radiological environmental monitoring program (REMP) and the RGPP. 2.3.1 Radiological Environmental Monitoring Program Pre-Operational Radiological Survey A pre-operational REMP was conducted to establish background radioactivity levels prior to operation of the Station. The environmental media sampled and analyzed during the pre-operational REMP were surface water, drinking water, atmospheric radiation, air particulates, and food. The results of the monitoring were detailed in the reports entitled, "Peach Bottom Atomic Power Station, Preoperational Radiological Environmental Monitoring Report for Units #2 & #3, September 1970 through August 1973", and "Peach Bottom Atomic Power Station-Environs Radiation Monitoring Program - Preoperational Summary Report for Units 2 and 3 - February 5, 1966 through August 8, 1973". A monitoring program was initiated in 1960 for Unit 1 and five annual reports were completed prior to its initial operation. Tritium was not analyzed during the pre-operational REMP for Unit 1. The pre-operational REMP (Units 2 and 3) analytical results from samples collected from surface water and drinking water wells indicate that tritium was detected in both surface water and drinking water samples. Tritium concentrations in surface water ranged from non-detect at the minimum detactable concentration (MDC) of 80 pCi/L to 1,300 pCi/L over the 3-year monitoring period (1970-1973). Tritium concentrations in drinking water (from on-Site water supply wells that have since been abandoned) ranged from non-detect at the MDC of 80 pCi/L to 790 +/- 90 pCi/L. Gross beta analytical results in surface water ranged from 1.2 +/- 1.1 pCi/L to 9.6 +/- 3.1 pCi/L. Gross beta analytical results in drinking water ranged from 1.4 +/- 1.2 pCi/L to 6.6 +/- 7. 0 pCi/L. Gamma spectrometry analytical results in surface water and drinking water were found very sporadically and at concentrations that nominaly exceed their respective MDC. Radiological Environmental Monitoring Program The REMP was initiated in 1960 and includes the collection of multi-media samples including air, surface water, groundwater, fish, milk, sediment, and vegetation. The samples are analyzed for beta and gamma-emitting radionuclides, tritium, iodine-131, and/or strontium as established in the procedures developed for the REMP. The samples are collected at established locations, identified as stations, so that trends in the data can be monitored. An annual report is prepared providing a description of the activities performed and the results of the analysis of the samples collected from the various media. The latest report reviewed by GHD was issued in May 2017 by Station personnel and is entitled "Annual Radiological Environmental GHD I Hydrogeologic Investigation Report j 11137316 (1) I Page 11
Operating Report No. 73, January 1, 2016 through December 31, 2016". This report concluded that the operation of the Station had no adverse radiological impact on the environment. The annual report is submitted to the NRC. 2.3.2 Radiological Groundwater Protection Program In 2006, Exelon instituted a comprehensive program to evaluate the impact of Station operations on groundwater and surface water near the Station. Exelon's RGPP (EN-PB-408-4160) incorporates guidance as detailed in NEI 07-07, American Nuclear Insurers' ANI Nuclear Liability Insurance Guideline 07-01, Potential for Unmonitored and Unplanned Off-Site Releases of Radioactive Material (March 2007), and EPRl's Groundwater Protection Guidelines for Nuclear Power Plants (November 2007, Industry Edition 1015118). The RGPP analytical plan is presented in Appendix C. According to the "Annual Radiological Groundwater Protection Report 1 January through 31 December 2015" (Exelon, 2017b), it was concluded that: "The operation of Peach Bottom Atomic Power Station had no adverse radiological impact on the environment, and there are currently no known active releases into the groundwater at Peach Bottom Atomic Power Station." 2.4 Investigations 2006-2017 Several investigations have been completed at the Station since October 2006. These investigations include mass flux calculations, Unit 1 investigation, Unit 3 CST and Torus Dewatering Tank investigation, Unit 2 and Unit 3 Reactor and Turbine Building investigation, Station efforts to identify potential tritium sources, and tritium age dating. Details of these investigations are presented below. 2.4.1 Mass Flux Calculations In September 2007, CRA prepared mass flux calculations to estimate the Curies of tritium in groundwater that were potentially migrating from groundwater at the Station to the Conowingo Reservoir and Rock Run Creek. CRA conducted the modeling analyses in response to the elevated tritium concentrations in MW-PB-4. In December 2011, CRA prepared updated mass flux calculations in response to the elevated tritium concentrations in monitoring wells east of the Unit 3 Turbine Building. Since the U2 and U3 Yard Drain Sump and Dewatering System (collection trench) captures some tritium prior to discharging to surface water points, CRA calculated the net tritium mass flux off the Station by subtracting both the background tritium mass and the mass captured by the pumping of the collection trench. Based upon the results of the 2007 and 2011 modeling analyses CRA concluded that the cumulative flux of tritium (i.e., total Curies) in groundwater to the reservoir was negligible compared to the Station's permitted discharge. In 2017, GHD updated the mass flux calculations based on the data collected since 2012. Based upon the results of the 2017 modeling analyses GHD concludes that the cumulative flux of tritium GHD I Hydrogeologic Investigation Report 111137316 (1) I Page 12
(i.e., total Curies) in groundwater to the reservoir was negligible compared to the Station's permitted discharge. The reports of the modeling analyses are presented in Appendix D. 2.4.2 PB-MW-4 Investigation* 2009 An investigation was completed to investigate elevated tritium detected in MW-PB-4. Monitoring wells MW-PB-24, MW-PB-25, MW-PB-26 and MW-PB-27 were installed as part of the evaluation of elevated tritium detected in MW-4. Analytical results from three groundwater samples (MW-PB-24, MW-PB-25, and MW-PB-26) collected on July 8, 2009 indicated tritium concentrations greater than the NEI 07-07 voluntary reporting threshold of 20,000 pCi/L. The highest concentration of tritium (127,252 pCi/L) was from a confirmation sample collected at monitoring well MW-PB-26. On July 31, 2009, Exelon submitted a voluntary, special report to the NRC regarding tritium in groundwater. 2.4.3 Moisture Separator Room (Unit 3)
- 2010 Subsequent Station investigations inside the Unit 3 Turbine Building identified water releases to the Moisture Separator Room. Cracks and degraded floor seems allowed pooled condensate water (up to 2,828,604 pCi/L) in the Moisture Separator room to migrate into the subsurface and outside the Unit 3 Turbine Building (Exelon, 2017c). In addition, water releases to this room also appear to have accumulated on the floor and migrated through an unused conduit bank (housing 10 pipes of 4-inch diameter) originating in the northeast corner of the Unit 3 Turbine Building. The conduit bank and associated piping penetrate the Moisture Separator Room floor and travel under the east wall of the Turbine Building into the overburden soils (atop the benched bedrock) near monitoring well MW-PB-25. From 2010 to 2011, sumps, the floor, and floor drains of the Unit 3 Moisture Separator room were repaired and sealed.
2.4.4 Moisture Separator Room (Unit 2)
- 2011 Monitoring wells MW-PB-29, MW-PB-30 and MW-PB-31 were installed in May 2011 to evaluate potential tritium releases from similar conditions as identified in Unit 3 Moisture Separator Room.
During nine sampling events in from June 2011 through July 2012, the maximum tritium concentration detected in these wells was 1,300 pCi/L, detected in MW-PB-30. In September 2012, water was found in the HVAC plenum east of the Unit 2 Moisture Separator Room. During an outage in October 2012, the HVAC was sealed, and the Unit 2 Moisture Separator Room floor was sealed with epoxy to prevent groundwater intrusion. 2.5 New Construction Since 2012, two buildings have been constructed. This buildings are shown on Figure 1.2. The FLEX building, installed in 2015, is southwest of the Owner Controlled Area checkpoint. The building houses emergency response equipment including diesel fueled pumps, generators, tractors, and miscellaneous support equipment. The building is outside of the protected area and not near any SSC's that contain licensed material. The subsurface was disturbed to a depth of about eight feet to permit the instllation of the building foundation and associated electrical cable runs. GHD I Hydrogeologic Investigation Report I 11137316 (1) I Page 13
The Unit 3 Adjustable Speed Drive (ASD) building is west of the Torus Dewatering Tank and Unit 3 CST moats. The ASD building houses components that regualte plant pump speed. The subsurface was disturbed to a depth of about four feet to permit the installation of the building foundation and associated electrical runs. 2.6 Remedial Actions No remedial actions are ongoing at the Station.
- 2. 7 Identified Areas for Further Evaluation GHD used the information presented in the above sections along with its understanding of the hydrogeology at the Station to identify AFEs. The establishment of AFEs is a standard planning practice in hydrogeologic investigations to focus the investigation activities at areas where there is the greatest potential for impact to groundwater. Figure 3.1 presents the AFE identified for this report.
AFE-Peach Bottom-2: Unit 2 and Unit 3 Reactor and Turbine Building Areas This area remains an AFE due to the elevated tritium concentrations (above 20,000 pCi/L through April 23, 2015) in the overburden groundwater. Review of the tritium trends and the FMCT timeline indicate a cause and effect relationship (i.e. tritium concentrations decreased following the Station's mitigation activities).

Field Activities to Support 2006 - 2017 Investigations The field investigations completed for this HIR were completed from May 2012 through December 2017 as part of the RGPP. As part of these field investigations, GHD and the Station completed the following activities: Groundwater and Surface Water Elevation Monitoring Groundwater and Surface Water Sampling Groundwater Temperature and Elevation Study 3.1 Groundwater And Surface Water Elevation Measurements In 2006, CRA selected and surveyed eight surface water monitoring locations (SW-PB-1 through SW-PB-8): two locations (SW-PB-1 and SW-PB-8) within the Conowingo Reservoir, two locations (SW-PB-6 and SW-PB-7) within Rock Run Creek, three locations (SW-PB-3 through SW-PB-5) within the Discharge Canal, and one location (SW-PB-2) within the Intake Pond. Surface water level measurements were collected at the surface water monitoring locations during the two 2006 groundwater level measurement events. The purpose of the surface water monitoring was to provide surface water elevation data to evaluate the groundwater/surface water interaction at the Station. Surface water level monitoring location SW-PB-9, along Rock Run Creek, replaced GHD I Hydrogeologic Investigation Report I 11137316 (1) I Page 14
SW-PB-7 and was surveyed in 2009. Several surface water monitoring locations are no longer accessible or identifiable. Since 2007, only SW-1, SW-PB-5, and SW-PB-6 have been routinely monitored for elevation data. Table 4.1 presents a summary of the monitoring well construction details. Since May 2006, CRA, Normandeau Associates (Normandeau), Station personnel, and Exelon Industrial Services have collected groundwater and surface water measurements. Figures 4.1 and 4.2 show the groundwater and surface water monitoring locations. A summary of groundwater elevations for the May 2012 to October 2017 monitoring events is provided in Table 4.2. Appendix E presents the monitoring well construction logs. Appendix F presents groundwater and surface water elevation data from 2006-2017. 3.2 Groundwater and Surface Water Sampling and Analysis Since September 2006, Normandeau, Station personnel, and Exelon Industrial Services have collected groundwater and surface water samples. Figures 4.1 and 4.2 show the groundwater and surface water monitoring locations, respectively. The low-flow purging technique is used to collect groundwater samples for tritium and other radionuclides analyses. Groundwater seep samples (SP-PB-1 through SP-PB-3) are also collected from seeps at the rock cliff face west of the Station and are shown on Figure 4.2. 3.3 Groundwater Temperature And Elevation Study In February 2012, CRA conducted a study of groundwater temperature and groundwater elevation in select monitoring wells at the Station. Continuous temperature data and groundwater elevation data, collected through the use of pressure transducers, was recorded in six monitoring wells east of the Unit 3 Turbine Building: MW-PB-4, MW-PB-12, and MW-PB-24 through MW-PB-27 to evaluate groundwater fluctuations. Temperature data, in conjunction with on-Station operational data or information, may serve as an indicator if the wells are experiencing surface water infiltration, precipitation and/or source leaks (process water with elevated temperature). CRA evaluated temperature data in conjunction with the water level data, precipitation data, and known tritium groundwater sources near the well(s). Review of the data indicated no definitive relationship between temperature and groundwater elevation in any of the overburden monitoring wells MW-PB-4, MW-PB-12, MW-PB-24, MW-PB-25, and MW-PB-26. Groundwater elevation and temperature changes (of relatively low magnitude) in bedrock monitoring well MW-PB-27 showed some correlation; however, the possible source of the correlation is unknown.

Results Summary This section presents a summary of the Station hydrogeology, and groundwater and surface water quality, updated for the period between May 2012 to December 2017. 4.1 Station Hydrogeology Figure 5.1 presents the monitoring well network in relationship to the geologic profile locations. Hydrogeologic profiles are presented on Figures 5.2 through 5.7. These profile locations were GHD I Hydrogeologic Investigation Report 111137316 (1) I Page 15
selected because of their close proximity to the AF Es and structures potentially influencing groundwater flow patterns, and to depict the tritium plume, groundwater flow direction, and receptors. These cross-sections show how the construction of the Station has significantly altered the original topography, subsurface, and has influenced the hydrology of the Station. Prior to construction, the bedrock sloped from the plateau to the west steeply down to the Conowingo Reservoir. During construction, significant blasting and excavation was completed along the bank of the river to create a platform for construction of the Station. This created a rock cliff from the higher topographic areas down to the bank of the reservoir. The Station structures were then constructed on a competent bedrock platform with much of the excavated material being used for surrounding fill. The fill was also used to extend the existing land surface into the reservoir. The extended land surface was used for parking lots and buildings not related to Station operations. 4.1.1 Groundwater Flow Directions Figures 5.8 and 5.9 present potentiometric surface contour maps based on the January 18, 2017 water level data collected by Exelon Industrial Services. The limit of saturated overburden shown on Figure 5.8 is based on the identification of areas where overburden material is absent (i.e., bedrock is exposed at the ground surface) and where the overburden is thin due to steep slopes. Essentially, this limit defines the extent of the water table aquifer at the Station. Due to limited monitoring points, the inferred extent of the overburden aquifer south of Rock Run Creek is more subjective than in the area to the north. Figure 5.8 indicates that lateral groundwater flow in the overburden aquifer is from west to east. Groundwater flows towards the surface water bodies and discharges either to the Conowingo Reservoir or the Discharge Canal, which subsequently discharges to the Conowingo Reservoir. Figure 5.9 for the bedrock aquifer shows a similar groundwater flow direction, west to east. 4.1.2 Man-Made Influences On Groundwater Flow The groundwater flow is impacted by Station structures and local geology. The foundations of the Reactor and Turbine Buildings are completed into competent bedrock at depths greater than the surrounding area; therefore, groundwater flow in the overburden migrates around the buildings. The Yard Drain Sump and Dewatering System influences groundwater flow immediately west of the Reactor and Turbine Buildings (see Figure 2.2). The purpose of the dewatering system is to prevent groundwater buildup from the seeps and infiltration from precipitation. The dewatering system is constructed of a 12-inch diameter porous concrete pipe connected to two sumps at each end. The system is under the service roadway within granular backfill west of the Reactor Buildings. The area is bounded on the west by the native bedrock, on the east by the Reactor and Radwaste Buildings, on the south by the concrete fill for the railroad, and on the north by the Recombiner Building and concrete fill. The dewatering system sump pumps have a capacity to pump up to 150 gpm and maintain a groundwater level between approximately 107 to 110 feet G.D. The invert elevation of the Unit 3 Yard Sump is at 105 feet G.D. The Yard Drain Sump and Dewatering System was inactive from 1995 through May 2006. During this period, groundwater intruded into the Station structures when groundwater elevations exceeded GHD I Hydrogeologic Investigation Report 111137316 (1) I Page 16
approximately 128 feet C.D.. The drain system was reactivated in May 2006 and has been active since that time. In November through December 2012, a dewatering project was completed as part of the buried pipe inspections northwest of the Administration Building. Two excavations were completed to approxiamtely 5 to 6 feet below the shallow water table, requiring construction dewatering. Pumping of groundwater during this project appeared to have a temporary effect on groundwater flow and quality (increased tritium) in wells east of the Turbine Building. The foundation of the FLEX Building is installed to a depth of eight feet bgs within soil. Depth to groundwater at monitoring well MW-PB-5, located within seven feet of the building, is typically between three and six feet bgs, therefore, the FLEX Building is installed into the top of the shallow water table. As a result the building does not present a significant barrier to groundwater flow. 4.1.3 Vertical Hydraulic Gradients Based on a review of the groundwater elevations at overburden well MW-PB-25 and nearby bedrock well MW-PB-27, the vertical gradient is upward from the bedrock to the overburden. This is expected due to the location of the Station in a regional discharge area along the Susquehanna River. The vertical gradient appears to vary, with piezometric/potentiometric head differences ranging from -0.37 to 1.24 feet. The average vertical gradient measured from 183 monitoring events (since March 2010) was approximately 0.48 feet. 4.1.4 Groundwater Flow Velocity Overburden The horizontal hydraulic gradient is estimated to be 0.01 feet per foot (ft/ft) based on a change in the water table elevation of approximately 2.90 feet over the 310 feet between MW-PB-24 and MW-PB-4 (January 2017). Based on slug testing, the hydraulic conductivity of the overburden is estimated to be 1.65 feet per day. Using the average hydraulic conductivity value, a range of historical horizontal hydraulic gradients of between 0.01 ft/ft to 0.02 ft/ft, and an estimated saturated porosity of 32 percent (Freeze, 1979), the horizontal groundwater flow velocity in the overburden aquifer was determined. The average saturated zone horizontal groundwater velocity ranges between approximately 0.05 to 0.10 feet/day, or between approximately 18 to 38 feet/year. Bedrock The horizontal hydraulic gradient is estimated to be 0.032 ft/ft based on a change in the water table elevation of approximately 6.38 feet over the 200 feet between MW-PB-19 and MW-PB-27 (January 2017). Based on slug testing (MW-PB-1 and MW-PB-3) the hydraulic conductivity of the bedrock is estimated to be 3.80 feet per day. Using the average hydraulic conductivity value, a range of historical horizontal hydraulic gradients of between 0.013 ft/ft and 0.040 ft/ft, and an estimated saturated porosity of 20 percent (Fetter, 1988), the horizontal groundwater flow velocity in the bedrock aquifer was determined. The average saturated zone horizontal groundwater velocity ranges between approximately 0.25 to 0. 76 feet/day, or between approximately 90 to 277 feet/year.

4.2 Groundwater Quality This section presents the results of groundwater sampling at the Station from May 2012 through December 2017. The tritium and other radionuclides results for the groundwater samples collected in 2016 through December 2017 are presented in Tables 5.1 and 5.2, respectively. 4.2.1 Summary of Tritium Analytical Results in Groundwater Tritium groundwater concentrations above the EPA drinking water standard of 20,000 pCi/L have been identified east of the Unit 3 Turbine Building. In February and March 2010, elevated tritium concentrations (above 20,000 pCi/L) were identified in bedrock monitoring well MW-PB-27 and overburden monitoring wells MW-PB-24, MW-PB-25, and MW-PB-26. Tritium concentrations have steadily declined in these wells through April 2015 when the Steam Leak in Unit 3 Moisture Separator Room occurred. Since the leaks was repaired tritium concentrations have been below 20,000 pCi/L since April 23, 2015. Appendix G presents the groundwater tritium analytical results from 2006 through 2017. During the August 14 through 17, 2017 quarterly RGPP sampling event, 22 monitoring wells were sampled including 15 overburden and seven bedrock wells. Figures 5.10 and 5.11 present tritium results, respectively, for the August 2017 overburden and bedrock groundwater sampling events. Figure 5.12 presents a tritium isoconcentration plume map (August 2017) for the overburden aquifer. Analytical results indicated 8 wells (from 6 overburden and 2 bedrock) out of the 21 groundwater samples collected were greater than the laboratory LLD of 200 pCi/L. No samples were greater than the USEPA drinking water standard for tritium of 20,000 pCi/L. The maximum concentration detected during the sampling event was 6,610 pCi/L at MW-PB-25. This concentration is significantly lower than the concentrations obtained in February 2010, when the maximum concentration detected was 300,000 pCi/L at MW-PB-25. Similar results were observed in analytical data reported for the December 11 through 12, 2017 sampling event, during which 22 monitoring wells were sampled. Fifteen overburden wells and seven bedrock wells were sampled during the event. Analytical results indicated groundwater collected from five overburden and one bedrock well contained concentrations of tritium greater than the laboratory LLD of 200 pCi/L. These wells also contained detections during the August 2017 sampling event. No samples were greater than the USEPA drinking water standard for tritium of 20,000 pCi/L. The maximum concentration detected during the sampling event was 13,900 pCi/L at MW-PB-25. While the concentration of tritium increased at MW-PB-25 from the August 2017 to December 2017 sampling event, tritium concentrations from four monitoring wells decreased (MW-PB-24, MW-PB-26, MW-PB-27, MW-PB-30). Elevated tritium concentrations are generally within the overburden and bedrock aquifers east of the Unit 3 Turbine Building. As a result of FMCT corrective action activities (e.g. Moisture Separator Floor sealing) in 2011 and 2015, tritium concentrations have declined. Figure 5.13 presents a tritium concentration trend graph for selected overburden monitoring wells east of the Unit 3 Turbine Building from May 2012 through December 2017. As shown on the figure, there is an overall decreasing trend in tritium in groundwater east of the Unit 3 Turbine Building. GHD I Hydrogeologic Investigation Report 111137316 (1) I Page 18
4.2.2 Summary of Other Radionuclides Analytical Results in Groundwater Gamma-emitting target radionuclides were not detected at concentrations that exceeded their respective laboratory LLD. Strontium 89 and Strontium 90 have not been detected during sampling events from 2008 though 2017. Non-target radionuclides Uranium 233/234, Uranium 235, and Uranium 238 were detected above laboratory LLDs, ranging in concentration from 0.1457to16.85 pCi/L, 0.1722 to 0.7043 pCi/L, and 0.1829 to 13.71 pCi/L, respectively. These concentrations are naturally occuring, contributable to local metamorphic schist bedrock, and are considered to be background. Similarly, other non-targeted radionuclides, such as potassium 40, were also included in the tables but excluded from discussion in this report. These radionuclides were either a) naturally occurring and thus not produced by the Station, orb) could be definitively evaluated as being naturally occurring due to the lack of presence of other radionuclides, which would otherwise indicate the potential of production from the Station. Appendix H presents the groundwater other radionuclide analytical results from 2006 through 2017. 4.3 Surface Water Quality This section presents the results of surface water sampling at the Station from May 2012 through August 2017. The tritium and other radionuclides results for the surface water samples collected from 2016 through August 2017 are presented in Tables 5.3 and 5.4, respectively. Appendix I presents the surface water tritium analytical results from 2006 through 2017. Appendix J presents the surface water other radionuclide analytical results from 2006 through 2017. 4.3.1 Summary Of Tritium Analytical Results In Surface Water And Seeps Tritium was not detected at concentrations greater than the laboratory LLD of 200 pCi/L in any of the surface water samples collected from 2006 through August 2017. Tritium has not been detected above the laboratory LLD since 2008 in any seep samples. 4.3.2 Summary of Other Radionuclides Analytical Results In Surface Water And Seeps Gamma-emitting target radionuclides were not detected at concentrations greater than their respective laboratory LLDs. Other non-targeted radionuclides were also included in the tables but excluded from discussion in this report. These radionuclides were either a) naturally occurring and thus not produced by the Station, orb) could be definitively considered as being naturally occurring due to the lack of presence of other radionuclides which would otherwise indicate the potential of production from the Station. 4.4 Precipitation Water Quality In 2008, a precipitation monitoring study at the Station indicated rainwater tritium concentrations ranging between non-detect to 2,700 pCi/L. The source of the tritium in precipitation water GHD I Hydrogeologic Investigation Report 111137316 (1) I Page 19
samples is rainwater recapture (i.e. scavenging) and precipitation washout. The Station currently monitors six precipitation water sampling points on a bimonthly basis. Five of the sampling points (1A, 1 B, 1 S, 1 SSE, 1 Z) are on average 1,650 feet from the Station center. The sixth sampling point (4M) is 45,989 feet from the Station center. Tritium was not detected at concentrations greater than the LLD of 200 pCi/L in any of the precipitation water samples collected from May 2012 through November 2017.

Exposure Pathway Assessment Three potential exposure pathways were considered during the evaluation of tritium in groundwater: Groundwater migration off the Station Property and potential exposure to drinking water users. Groundwater migration off the Station Property to a surface water body and potential public exposure to surface water. Groundwater migration on the Station Property to a surface water body and potential exposure to drinking water. Based upon the groundwater and surface water data provided and referenced in this investigation, none of the potential receptors are at risk of exposure to concentrations of tritium in excess of the USEPA drinking water standard (20,000 pCi/L). The following sections provide an overview of each of the potential exposure pathways for tritium in groundwater. 5.1 Potential Groundwater Migration To Drinking Water Users On And Off The Station Property Evaluation of groundwater flow at the Station indicates that the groundwater discharges directly to the Intake Pond, Rock Run Creek, Conowingo Reservoir or to the Discharge Canal, which subsequently discharges to the Conowingo Reservoir. The Conowingo Reservoir is a source of drinking water for the Station. Drinking water at the Station is obtained from the Intake Pond and is sampled from a tap in the Plant Services Building. Tritium results for surface water samples collected from the Conowingo Reservoir, Intake Pond, and from domestic water samples are below the LLD of 200 pCi/L. Analytical results from samples collected from the Intake Pond and domestic water samples are reported in the Station RGPP. The Peters Creek Schist, which is a low yielding formation, is used for domestic water supply in the surrounding area. There are domestic wells upgradient of the Station, however, there are no off-Station domestic water supply wells between the Station and discharge points. The bedrock beneath the Station does not readily store or transmit groundwater. There are no known deep aquifers of any extent in the region and the bedrock becomes more competent with depth. The potential for groundwater flow inland from the Station is deemed highly improbable (Dames & Moore, 1968). Therefore, it is highly unlikely that off-Station water supply wells could be impacted from a potential tritium release to groundwater. In summary, there is no current risk of exposure to tritium above the EPA threshold of 20,000 pCi/L associated with groundwater ingestion on or off the Station property. GHD I Hydrogeologic Investigation Report I 11137316 (1) I Page 20
5.2 Potential Groundwater Migration to Surface Water Users on And Off the Station Property Groundwater ultimately discharges to the Conowingo Reservoir; therefore, there is a potentially complete exposure route to drinking water users (from downstream surface water withdrawals) and to recreational users of surface water including boaters, fishermen, and swimmers. The Conowingo Reservoir is a public water supply source for the City of Baltimore, Harford County (Maryland), and the Chester (Pennsylvania) Water Authority. Tritium results for surface water samples (SW-PB-1, SW-PB-5, and SW-PB-6) collected from 2006 through 2017 are below the laboratory LLD of 200 pCi/L. Tritium results for seep samples (SP-PB-1 through SP-PB-3) collected from June 2008 through 2017 are below the laboratory LLD of 200 pCi/L. Tritium has not been detected above the laboratory LLD since 2009 in any seep samples. Seeps are not a direct source of tritium to major surface water bodies. Furthermore, the seeps do not represent a surface water exposure point for recreational users. Although a potential exposure route exists, there is minimal potential for tritium exposure from recreational activities in surface water from migration of groundwater based on the analytical results. In summary, a potential exposure pathway to surface water exists; however, the tritium concentrations detected at the Station present no current risk to the potential surface water receptors. 5.3 Other Radionuclides Radionuclides were not detected at concentrations greater than their respective MDCs in the groundwater and surface water samples collected. Additional radionuclides were also included in the tables but excluded from discussion in this report. These radionuclides were either a) naturally occurring and thus not produced by the Station, orb) could be definitively evaluated as being naturally occurring due to the lack of presence of other radionuclides which would otherwise indicate the potential of production from the Station.

Conceptual Site Model This section presents GHD's conceptual site model of groundwater and tritium migration at the Station. The geology beneath the Station consists of fill, weathered bedrock, and competent bedrock (Peters Creek Schist) although the construction of the Station has significantly altered the original topography and subsurface. The thickness of the fill (excavated rock) ranges from 2 to 34 feet. In general, the thickness of the fill increases from the base of the rock cliff west of the Station structures to the east towards the Conowingo Reservoir. The upper 10 to 20 feet of bedrock was typically weathered. More competent bedrock is encountered beneath the weathered rock. The groundwater that flows in the overburden is affected by the building foundations, which extend into the competent bedrock. The overburden aquifer pinches out to the west behind the building structures at the base of the rock cliff. In addition, groundwater flow on the west side of the Reactor GHD I Hydrogeologic Investigation Report I 11137316 (1) I Page 21
Buildings is affected by accumulation of groundwater in the overburden. Pumping of the Yard Drain System on the west side of the Unit 2 and Unit 3 Reactor Buildings serves to lower the groundwater table and reduce mounding conditions and infiltration into the structures. Groundwater flow east of the building structures flows east toward the Intake Pond, Conowingo Reservoir, Rock Run Creek, and the Discharge Canal. The Peters Creek Schist, which is the competent bedrock beneath the Station, has relatively low primary and secondary porosity. Therefore, the bedrock does not readily store and transmit groundwater. This is supported by documented low well yields (ranging from two to six gpm) in the on-Station, non-potable water supply wells. The vertical gradient is upward from the bedrock to the overburden as expected due to the location of the Station in a regional discharge area. The analytical results for the groundwater samples collected at the Station indicate that groundwater impacts (above 20,000 pCi/L) were limited to an area immediately east (downgradient) of the Unit 3 Turbine Building. Tritium isoconcentration maps from select sampling events between August 2009 through August 2017 are presented on Figure 7.1. The tritium plume extends downgradient east towards the Administration Building and the Intake Pond. The tritium impacts are sourced from the Unit 3 Moisture Separator Room, upgradient of MW-PB-25 (the monitoring well containing the highest concentrations of tritium). The impacted groundwater flows east-northeast towards the Intake Pond, is then pumped through the intake structure and cooling water system, and discharged to the Discharge Canal. From August 2009 through August 2017, the extent and magnitude of the tritium plume have diminished. There is no indication from the HIR investigation that tritium-impacted groundwater from the area of MW-PB-25 is migrating off-Station. Results of this investigation indicate that the tritium plume is the likely result of residual tritiated condensate water that leaked through degraded floor seams and/or pipe penetrations in the Unit 3 Turbine Building Moisture Separator Room Area. Three potential exposure pathways were considered during the evaluation of tritium in groundwater: Groundwater migration off the Station Property and potential exposure to private and public groundwater users. Groundwater migration off the Station Property to a surface water body and potential public exposure to surface water. Groundwater migration on the Station Property to a surface water body and potential exposure to drinking water. Based upon the groundwater, surface water, and domestic water sample data provided and referenced in this investigation, the results of the tritium mass flux calculations, and evaluation of the potential exposure pathways, none of the potential receptors are at risk of exposure to concentrations of tritium in excess of the USEPA drinking water standard (20,000 pCi/L).

Conclusions In accordance with the NEI 07-07 Guidance, the hydrogeology should be periodically reviewed and updated. The following items were reviewed since the original HIR was completed in 2006: GHO I Hydrogeologic Investigation Report 111137316 (1) I Page 22
Hydrogeologic Studies Subsurface Disturbances and Major Construction Changes in On-Station Property or Off-Station Groundwater Supplies Documented Spills or Leaks (Reported to Agencies) Based on this hydrogeologic investigation, GHD concludes: Groundwater Flow The overburden groundwater flows from west to east across the Station with discharge to the Conowingo Reservoir. However, overburden groundwater is forced to flow around the major Station structures that are completed into the underlying bedrock. Groundwater Quality Tritium is not migrating off the Station at concentrations greater than the USEPA drinking water standard of 20,000 pCi/L. Between May 2012 and December 2017, tritium concentrations in groundwater east of the Turbine Building were detected at concentrations greater than the USEPA drinking water standard (up to 38, 100 pCi/L). As a result of completing several corrective action activities in 2015, all groundwater results have been less than the USEPA drinking water standard since April 23, 2015. Gamma-emitting radionuclides associated with licensed plant operations were not detected at concentrations greater than their respective laboratory LLDs at any sample location. Strontium 89 and Strontium 90 were not detected at concentrations greater than their respective LLDs at any sample location. Surlace Water and Seep Quality Tritium was not detected at concentrations greater than the LLD (200 pCi/L) in any surface water samples collected from 2006 through 2017. Since 2008, tritium has not been detected above the laboratory LLD in any seep samples. Gamma-emitting radionuclides associated with licensed plant operations were not detected at concentrations greater than their respective LLDs. Precipitation Tritium results in precipitation water samples were not detected at concentrations greater than the LLD (200 pCi/L) from May 2012 through November 2017. AFEs Two of the three AFEs identified in 2006 indicate no current impact to groundwater and are not retained as AFEs in 2017. GHD I Hydrogeologic Investigation Report I 11137316 (1} I Page 23
AFE-Peach Bottom-2: Unit 2 and Unit 3 Reactor and Turbine Building Areas continues to be identified as an AFE. The likely source (Unit 3 Moisture Separator Room floor) of elevated tritium concentrations in groundwater has been mitigated via corrective actions. Subsurface Disturbances and Major Construction There were three subsurface disturbance projects from May 2012 through May 2017. Two of the projects were for construction of the ASD Building and the FLEX Building. Construction of the two buildings has not affected groundwater conditions at the Station. The dewatering project for the buried pipe inspection program was completed in November through December 2012. Pumping of groundwater during this project appeared to have a transient effect on groundwater conditions (flow) and quality (increased tritium) in wells east of the Turbine Building. Changes in On-Station Property or Off-Station Groundwater Supplies No significant changes occurred to on-Station or off-Station groundwater supplies. Documented Spills or Leaks (Reported to Agencies) On January 24, 2015, there was a there was a release of approximately 40 gallons of hydraulic fluid from an elevator. The spill was deemed non reportable following evaluation and Discussion with Pennsylvania Department of Environmental Protection. On April 15, 2015, a leak in the Unit 3 Moisture Separator Area resulted in an increase in tritium activity in monitoring wells adjacent to the Unit 3 Turbine Building. The leak was reported to the NRC, Commonwealth of Pennsylvania, and State of Maryland on May 15, 2015. Status of Remedial Actions No remedial actions are ongoing at the Station.

Recommendations The following presents GHD's recommendations for proposed activities to be completed at the Station. 8.1 Data Gaps Based on the results of this hydrogeologic investigation, GHD has identified the following data gaps: GHD understands that monitoring well PB-MW-11 is in poor condition, and is not currently sampled. GHD recommends that the Station repair monitoring well PB-MW-11 to it's original condition. GHD I Hydrogeologic Investigation Report I 11137316 (1) I Page 24
8.2 Groundwater Monitoring Based upon the information collected to date, GHD recommends that Exelon continue the RGPP sampling per the NEI 07-07. GHD is aware that the Station would like to repair or replace concrete well pads on seventeen monitoring wells in the protected area (MW-PB-2, MW-PB-3, MW-PB-4, 12, 13, 19-22, 24-31) 8.3 Surface Water Monitoring Based upon the information collected to date, GHD recommends that Exelon continue the RGPP sampling per the NEI 07-07.
