Oyster Creek Nuclear Generating Station Renewed Facility Operating License No. DPR-16 NRG Docket Nos. 50-219 and 72-15 Request to Reinitiate Consultation Regarding the OCNGS Sea Turtle Incidental Take Statement
Reference:

-"Oyster Creek Nuclear Generating Station," dated November 21, 2011 (ML 12006A217)
- 2) Letter from M. Gallagher (Exelon Generation Company, LLC to U.S. Nuclear Regulatory Commission
-"Oyster Creek Nuclear Generating Station -Post-Shutdown Decommissioning Activities Report," dated May 21, 2018 (ML18141A590)
The Oyster Creek Nuclear Generating Station (OCNGS) Renewed Facility Operating License No. DPR-16 requires Exelon Generation Company, LLC (Exelon) to comply with the terms and conditions of the Incidental Take Statement (ITS) associated with certain sea turtles that is "in effect or as subsequently issued" by the National Oceanic and Atmospheric Administration's (NOAA) National Marine Fisheries Service (NMFS) in a Biological Opinion. The Biological Opinion most recently issued by NMFS in support of the U.S. Nuclear Regulatory Commission's (NRG) renewal of the OCNGS operating license is dated November 21, 2011 (Reference 1 ). The purpose of this letter is to request that the NRG reinitiate the Endangered Species Act (ESA) Section 7 consultation that was the basis for the ITS issued on November 21, 2011 (2011 ITS). Such reinitiation would allow NMFS to consider amending the ITS to be more relevant to current circumstances at the OCNGS, which include permanent cessation of operation and the corresponding reduced effects on listed species. Reinitiation of ESA Section 7 consultation between the NMFS and another federal agency is required if the other agency retains control over an action leading to an initial ESA Section 7 consultation, and if: (1) the amount or extent of taking specified in the ITS is exceeded (50 CFR 402.16(a));
(2) new information reveals effects of the action that may not have been previously considered (50 CFR 402.16{b));
(3) the identified action is subsequently modified in a manner that causes an effect to listed species or critical habitat that was not considered in the existing U.S. Nuclear Regulatory Commission OCNGS Sea Turtle Incidental Take Statement Docket Nos. 50-219 and 72-15 October 16, 2018 Page 2 biological opinion (50 CFR 402.16(c));
or (4) a new species is listed or critical habitat is designated that may be affected by the action leading to the initial ESA Section 7 consultation (50 CFR 402.16(d)).
Exelon has evaluated the current OCNGS operating status against these criteria and concluded that criterion (3) justifies reinitiation of the ESA Section 7 consultation between the NRC and NMFS that led to the 2011 ITS. The basis for this conclusion is summarized below. First, no unconsidered effects on protected species have been revealed to trigger criterion (2). Regarding criterion (4), Exelon reviewed the U.S. Fish and Wildlife Service website during 2018 (Reference
- 2) for listed species that are known or believed to occur in New Jersey and found that the following species have been added to the list since the 2011 ITS was issued for OCNGS:
- Red Knot
- Northern Long-Eared Bat According to the Red Knot profile on the website, Red Knot habitat includes Atlantic and bay beaches and mudflats.
Threats to the Red Knot include sea level rise; coastal development; shoreline stabilization; dredging; reduced food availability at stopover areas; disturbance by vehicles, people, dogs, aircraft, and boats; and climate change. Other than the potential for dredging, the planned post-shutdown decommissioning activities at OCNGS will not create any of these threats to the Red Knot. Additionally, the Red Knot does not typically reside in water bodies like Oyster Creek or Forked River. As discussed in the OCNGS Post-Shutdown Decommissioning Activities Report (PSDAR) (Reference 2), if dredging is pursued between the barge landing and Barnegat Bay in order to provide enough depth for the barge shipment, it would be conducted under U.S. Army Corps of Engineers (USAGE) and appropriate New Jersey Department of Environmental Protection (NJDEP) Division of Land Use Regulation permits. Exelon has reserved space for dredge spoils in an existing State of New Jersey dredge spoils basin on property adjacent to Oyster Creek. Because decommissioning activities at OCNGS would utilize an existing barge landing and dredge spoils basin, there would be no changes to offsite land use patterns.
The habitat of the Northern Long-Eared Bat includes caves and mines in the winter and wooded areas in the summer. White-nose syndrome, the cause of which is not related to any OCNGS decommissioning activity, is the predominant threat to this bat, according to the U.S. Fish and Wildlife Service Environmental Conservation Online System (ECOS). Hence, the planned shutdown decommissioning activities at OCNGS will not pose a threat to the Northern Eared Bat. Atlantic sturgeon and shortnose sturgeon are federally-listed endangered aquatic species found in the Delaware River in New Jersey. However, neither species was identified by resource agencies as being of concern when the NRC reviewed the OCNGS application for operating license renewal during 2006. In addition, no shortnose or Atlantic sturgeon have been collected at OCNGS since the 2011 ITS was issued (Reference 2). Hence, because the planned post-shutdown decommissioning activities at OCNGS are not anticipated to create or pose any threats to either the Northern Long-Eared Bat or the Red Knot, and both Atlantic and shortnose sturgeon continue to be absent at OCNGS, Exelon concludes that no newly listed species or newly identified critical habitat is present to trigger criterion (4). Regarding criterion (3), OCNGS ceased power operations on September 17, 2018, defueled, and began execution of post-shutdown decommissioning activities as described in the OCNGS U.S. Nuclear Regulatory Commission OCNGS Sea Turtle Incidental Take Statement Docket Nos. 50-219 and 72-15 October 16, 2018 Page3 PSDAR (Reference 2). Upon shutdown of the reactor, OCNGS discontinued the use of the Dilution Water System (DWS). This eliminated sea turtle impingement risk at the DWS. OCNGS will continue using two Circulating Water System (CWS) pumps (approximately 250,000 gpm [360 MGD]) for approximately 60 days after power operations ceased. Beyond the 60-day period, plant heat will be removed by the Service Water (SW) and Emergency Service Water (ESW) systems (approximately 12,000 gpm [17.3 MGD]) until all spent fuel has been moved from the Spent Fuel Pool to the Independent Spent Fuel Storage Installation (ISFSI), which is scheduled for approximately March 2024. This change represents a greater than 98% reduction in intake flow from full power operation, which significantly reduces sea turtle impingement risks. Hence, post-shutdown decommissioning activities will have meaningfully less effect on threatened and endangered sea turtles than was previously contemplated in the 2011 ITS. For that reason, Exelon believes reinitiation of the ESA Section 7 consultation under criterion (3) (50 CFR §402.16(c))
is justified in order to fashion a revised ITS that is more relevant to current OCNGS circumstances.
Regarding criterion (1), Table 2 in the Attachment indicates the number of loggerhead sea turtles taken at the OCNGS intake structures from 2012 through September 2018 exceeds the limit for full power operation specified in the 2011 ITS. Exelon, however, does not recommend reinitiation of the ESA Section 7 consultation based on criterion (1) because the permanent shutdown in September 2018 makes the exceedance of the incidental take limit irrelevant with respect to future effects of OCNGS on listed species. The attachment to this letter provides additional supporting information.
Express modifications to the "reasonable and prudent measures" as well as the mitigating "terms and conditions" enumerated in the 2011 ITS are also suggested in the attachment.
No commitments to the NRC are made in this letter. If you have any questions concerning this submittal, please contact Paul Bonnett at (61 O) 765-5264. Respectfully, Michael P. Gallagher Vice President, License Renewal & Decommissioning Exelon Generation Company, LLC

No observed takes of endangered or threatened species occurred at the OCNGS prior to 1992. However, following dredging in the intake and discharge canals in early 1992, sea turtle impingements began occurring at the OCNGS intake structure.
A detailed summary of such impingements from 1992 through 2011 is provided in the 2011 Biological Opinion and its accompanying Incidental Take Statement (ITS) (Reference 1 ), which specifies cumulative take limits for the period from 2012 through 2029 and was used to support the NRC's first renewal of the OCNGS operating license. The table below summarizes sea turtle impingements from 1992 through September 2018. Table 1: OCNGS Sea Turtle incidental take data from 1992 through September 2018 Kemp's ridley Loggerhead Green TOTAL 1992 to 2010 50 11 8 69 2011 6 1 1 8 2012 4 0 1 5 2013 7 2 0 9 2014 7 1 0 8 2015 8 0 4 12 2016 1 1 1 3 2017 2 1 1 4 Jan to Sept 2 2 0 4 2018 TOTAL (1992 87 19 16 122 to 2018) PROPOSED ACTION On December 9, 2010, Exelon became a party to an Administrative Consent Order (ACO) with the New Jersey Department of Environmental Protection (NJDEP) (Reference 2). In the ACO, Exelon agreed to cease power production at OCNGS no later than December 31, 2019, rather than operate the facility until 2029, when the station's renewed U.S. Nuclear Regulatory Commission (NRC) operating license expires. Accordingly, NJDEP agreed to issue a new draft New Jersey Pollutant Discharge Elimination System (NJ PD ES) permit containing a determination, pursuant to the Clean Water Act Section 316(b), that existing measures being taken at OCNGS to mitigate fish and shellfish impingement and entrainment effects represent the best technology available for the facility's cooling water intake through the time of permanent cessation of power Attachment Reinitiation of Consultation With NOAA Docket Nos. 50-219 and 72-15 Page A-2 generation operations (i.e., shutdown) at the facility and the associated reduction in intake volume commensurate with post-shutdown activities.
In the 2011 Biological Opinion, NMFS explains that: "On October 12, 2011, the NRG issued a letter to Exelon confirming that, NRG had received Exelon's notice of intent to permanently cease operations of the OGNGS by no later than December 31, 2019. NMFS requested clarification from the NRG on the status of the OGNGS license after 2019. NRG has indicated that the operating license will remain in effect until April 2029, regardless of Exelon's stated plans to cease operations early. As the term of the license has not changed and because, under the terms of the existing license, operations are authorized until April 9, 2029, NMFS has considered the potential impacts of the continued operation of the facility through, the end of its operating license. NMFS anticipates that, a future Section 7 consultation between NMFS and NRG would consider effects to listed species from any decommissioning plans or other activities associated with the future termination of operations at OGNGS." (Reference
- 1) By letter dated February 14, 2018, Exelon certified, pursuant to 1 O CFR 50.82(a)(1
)(i) and 1 O CFR 50.4(b)(8}, that OCNGS would permanently cease operations no later than October 31, 2018 (Reference 3). On May 21, 2018, OCNGS submitted to the NRC the Post-Shutdown Decommissioning Activities Report (PSDAR) (Reference 4). Subsequently, the OCNGS ceased operations on September 17, 2018 (Reference 5). Exelon has provided the NRC certification pursuant to 10 CFR 50.82(a)(1
)(ii) that all fuel has been removed from the reactor vessel and placed in the Spent Fuel Pool (Reference 6). Based on the latter two submittals, in accordance with 1 O CFR 50.82(a)(2)
OCNGS is no longer authorized to operate the reactor. Upon shutdown of the reactor, OCNGS discontinued the use of the Dilution Water System (DWS). This eliminated sea turtle impingement risk at the DWS. OCNGS will continue using two Circulating Water System (CWS) pumps (approximately 250,000 gpm [360 MGD]) for approximately 60 days after power operations ceased. Beyond the 60-day period, plant heat will be removed by the Service Water (SW) and Emergency Service Water (ESW) systems (approximately 12,000 gpm [17.3 MGD]) until all spent fuel has been moved from the Spent Fuel Pool, to the Independent Spent Fuel Storage Installation (ISFSI), which is scheduled for approximately March 2024. This change represents a greater than 98% reduction in intake flow from full power operation, which significantly reduces sea turtle impingement risks. Considering the above information, Exelon submits that actual cessation of OCNGS operations on September 17, 2018, and certification of permanent fuel removal on September 25, 2018, removes all options involving continued operation of the facility through the end of its renewed operating license term on April 9, 2029. Because, cessation of power operations has less effect than the continued power operations contemplated in the 2011 ITS, Exelon is requesting that the NRC reinitiate the formal consultation with NMFS that concluded with NMFS issuance of the 2011 Biological Opinion and ITS with respect to NRC's action to extend the OCNGS operating license for an additional 20 years beyond the initial licensed term. Because the OCNGS licensed term remains unmodified, this reinitiation request is appropriate to address changed circumstances regarding effects on threatened and endangered sea turtles during the extended license term.
Attachment Reinitiation of Consultation With NOAA Docket Nos. 50-219 and 72-15 Page A-3 EVALUATION The 2011 Biological Opinion examined the likely effects (direct and indirect) of OCNGS full power operation through April 9, 2029. At the time the 2011 Biological Opinion was written, the potential ways in which OCNGS operation was expected to affect threatened and endangered sea turtles included:
impingement at either the circulating water system or dilution water system intake trash racks; capture of free swimming sea turtles in the intake bays; altering the abundance or availability of sea turtle prey items; and altering water quality through the discharge of heated and chlorinated effluent.
Impingement and Capture of Sea Turtles (September 2018 through 01 2024) According to the 2011 Biological Opinion, "[i]t is unclear why sea turtles enter the Forked River and encounter the OCNGS intake structures.
In order to be present at the intake bays, live sea turtles must actively swim from Barnegat Bay into the Forked River and continue downstream to the intake bays. As the current velocity does not increase until within several meters of the intakes, it does not appear that sea turtles are subject to inescapable currents in the Forked River which would draw them to the intakes." Hence, only when sea turtles approach within relatively close proximity to the OCNGS intake structures does impingement become a concern. And even then, the 2011 Biological Opinion concludes that it is likely that sea turtles impinged on the intake trash bars are already stressed, which may increase the turtles' susceptibility to suffocation or drowning.
Furthermore, in the plant discharge canal, sea turtles have never been vulnerable to impingement because water flow is away from the plant equipment.
During full power operation, the total maximum intake water flow from Barnegat Bay via the south branch of the Forked River was approximately 1 million gallons per minute (gpm). At that flow rate, velocity in the intake canal was typically less than 2.0 feet per second (fps). Since power operations have ceased, the intake flow rate has been reduced to 250,000 gpm. In December 2018, intake flow will be reduced to 12,000 gpm, which is attributed to the Service Water System pumps that continue to provide cooling for the Spent Fuel Pool. The Spent Fuel Pool cooling will be needed until all spent fuel has been moved into dry storage, which is projected to occur by approximately March 2024, which is about 5.5 years after plant shut down (Reference 4, Table 2). Hence, the OCNGS intake flow rate between December 2018 and the first quarter of 2024 will be reduced to less than two percent of the flow rate during full power operation (i.e., 12,000 + 1x10 6 = 0.012). The accompanying flow velocity in the intake canal at this reduced intake flow rate will be less than 0.02 fps. Exelon submits that the significantly reduced intake water volume and flow rate in the intake canal should reduce impingement effects on threatened and endangered sea turtles by a directly proportional percentage during the 5.5 years following plant shut down. Accordingly, Exelon anticipates the reduced cumulative impact indicated in Table 2 on two federally endangered species (Kemp's ridley sea turtle and green sea turtle) and one federally threatened species (loggerhead sea turtle).

- The OCNGS renewed operating license will expire in April 2029. As sea turtles are only present from May to October, NMFS concluded that no sea turtles are likely to be captured or impinged in 2029. Thus, NMFS considered cumulative impacts over the 16 "sea turtle seasons" in 2012 through 2028. Effects on Prey and Water Quality (December 2018 through Q1 2024) NMFS evaluated both direct and indirect effects of OCNGS full power operation during 2012 through 2029 on protected sea turtles resulting from OCNGS effects on water temperature and water quality. Regarding prey, the 2011 Biological Opinion states that there is no evidence that sea turtles have been affected by impacts on sea turtle prey caused by either impingement and entrainment or elevated discharge water temperatures associated with OCNGS. Also, the 2011 Biological Opinion states that the level of chlorination at the OCNGS is believed to have an insignificant effect on the ability of sea turtles to successfully forage, and there is no evidence that the OCNGS heated effluent has increased sea turtle vulnerability to cold stunning. During the post-shutdown period from December 2018 through the first quarter (01) of 2024, impacts on sea turtle prey caused by either impingement and entrainment or discharge water chlorination will be a miniscule fraction of such impacts during full power operation.
Effects After Q1 2024 Until License Termination All spent fuel will have been moved from the Spent Fuel Pool to the ISFSI pad by the end of the first quarter in 2024. Therefore, after that time no effects resulting from OCNGS cooling water systems will continue, and other decommissioning activities are not likely to adversely impact any protected sea turtle species (Reference 4, p. 33). CONCLUSIONS During the post-shutdown period from September 2018 through the first quarter of 2024, the cumulative effects of impingement and capture of sea turtles will be a small fraction of full power Attachment Reinitiation of Consultation With NOAA Docket Nos. 50-219 and 72-15 Page A-5 operational impacts. The greatly reduced intake flow rate due to the suspension of the DWS and CWS flows and only the use of the SW and/or ESW systems reduces the risk of sea turtle impingements caused by the OCNGS intake structures to essentially zero in any particular year. Therefore, captures, injuries and deaths of sea turtles are not expected to occur as a result of intake flows at OCNGS. Furthermore, effects on sea turtle prey and water quality during that same period will be immeasurable or nonexistent.
Between the end of the first quarter in 2024 and license termination, endangered and threatened sea turtles will be unaffected by OCNGS cooling water systems, and other decommissioning activities are not likely to adversely impact any protected sea turtle species (Reference 4). Accordingly, Exelon requests that the NRC seek reinitiation by NMFS of ESA Section 7 consultation for the purpose of reevaluating the cumulative take of threatened and endangered sea turtles expected to occur between September 17, 2018 and termination of the OCNGS operating license. Table 3 itemizes Exelon's proposed changes to the "reasonable and prudent measures" (RPMs) identified in the 2011 ITS (Reference 1 ), and Table 4 itemizes Exelon's proposed changes to the "Terms and Conditions" set forth in the 2011 ITS for implementing the RP Ms. Table 3: Proposed Changes to "Reasonable and Prudent Measures" Stated In the 2011 ITS Suggested Text of "Reasonable and Revised Text of Prudent Measures" from the "Reasonable Explanatory Comments 2011 ITS and Prudent Measures" 1.

removal will be accomplished only by the Service Water (SW) and/ or Emergency Service Water (ESW) systems (approximately 12,000 gpm or 17.3 MGD) until all spent fuel has been moved from the Spent Fuel Pool to the Independent Spent Fuel Storage Installation (lSFSl) Pad (approximately March 2024). Accordingly, incidental take of sea turtles after December 2018 will not be caused by the CWS and DWS intake flows. The greatly reduced intake flow rate from using the SW and/or ESW systems reduces the risk of sea turtle impingements caused by the OCNGS intake structures to essentially zero in any particular year. Thus, prevention and minimization of incidental sea turtle takes will Attachment Reinitiation of Consultation With NOAA Docket Nos. 50-219 and 72-15 Page A-6 Suggested Text of "Reasonable and Revised Text of Prudent Measures" from the "Reasonable 2011 ITS and Prudent Measures" 2.

to attempt to identify the longer cause of death, particularly necessary whether the sea turtle died as a result of interactions with the intakes. Explanatory Comments no longer be within OCNGS control, and the mandatory program should be modified to focus on monitoring and mitigation.
The greatly reduced intake flow rate beginning in December 2018 will reduce the risk of sea turtle impingements caused by the OCNGS intake structures to essentially zero in any particular year. Accordingly, merely sighting a sea turtle near the intake structures should not warrant reporting.
However, if a sea turtle is recovered at the OCNGS intake structures, Exelon agrees that NMFS must be notified, regardless of the condition of the turtle. The greatly reduced OCNGS intake water flow rate after December 2018 will reduce the risk of sea turtle impingements caused by the OCNGS intake structures to essentially zero in any particular year. Even so, Exelon agrees that notification of NMFS would be required upon recovery of a sea turtle at an OCNGS intake structure, and Exelon agrees to transport recovered sea turtles to an appropriate facility for evaluation.
The greatly reduced OCNGS intake flow rate beginning in December 2018 is not expected to cause the death of a healthy sea turtle; therefore, OCNGS should not be required to necropsy recovered sea turtles that die. Even so, Exelon agrees that notification of NMFS would be required upon recovery of a dead sea turtle, regardless of the cause of death, and Exelon agrees to transport such sea turtles to an appropriate facility for evaluation as a measure for implementing RPM #3.

If a sea turtle is recovered at the OCNGS intake structures, it would be handled during daylight hours to support RPM#1. Although the greatly reduced OCNGS intake water flow after December 2018 is not expected to capture sea turtles, Exelon agrees that equipment should be maintained for use by OCNGS personnel if a sea turtle requires rescue or recovery at the OCNGS intake structures.

Information in If a recovered Appendix IV will assist in sea turtle has Explanatory Comments Although Exelon agrees that notification of NMFS would be required upon recovery of a sea turtle at the OCNGS intake structures, and Exelon agrees to implement RPM #1 by transporting recovered sea turtles to an appropriate facility for evaluation, OCNGS personnel should not be required to resuscitate comatose sea turtles because the greatly reduced OCNGS intake water flow after December 2018 is not expected to capture turtles, and therefore, not expected to cause them to become comatose.
The greatly reduced OCNGS intake water flow after December 2018 is not expected to capture sea turtles. Accordingly, requiring OCNGS personnel to notify NMFS within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of every sea turtle sighting in the OCNGS vicinity is not warranted due to the reduced risk of capture. The greatly reduced OCNGS intake water flow after December 2018 is not expected to capture sea turtles. However, if a sea turtle is recovered at an OCNGS intake structure, Exelon agrees that notification of NMFS would be required, and additional documentation is warranted for circumstances in which a recovered sea turtle has been incidentally harmed by facility components.

This report will be used to identify trends and further must include, as detailed above, all necropsy reports, incidental take reports, photographs (if not previously submitted), a record of all sightings in the vicinity of OCNGS, and a record of when inspections of the intake trash bars were conducted for the 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> prior to the take. The annual report must also include any potential measures to reduce sea turtle impingement or mortality at the intake structures.
This annual report must also include information on arrangements made with a STSSN facility to handle sea turtles taken in the coming year. The report must also include all necropsy reports. At the time the report is submitted, NMFS will supply NRG and Exelon with any information on changes to reporting requirements (i.e., staff chanoes, phone or fax Explanatory Comments The greatly reduced OCNGS intake water flow after December 2018 is not expected to capture sea turtles. However, if a sea turtle is recovered at an OCNGS intake structure, Exelon agrees that notification of NMFS would be required.
Furthermore, additional documentation would be provided to NMFS for circumstances in which the recovered sea turtle has been incidentally harmed by facility components.
Nevertheless, Exelon anticipates that during the post-shutdown period from December 2018 through license termination the number of sea turtles recovered at OCNGS intake structures will be so small that the requirement for submittal of an annual summary report is no longer warranted.

Nevertheless , because the greatly reduced OGNGS intake water flow after December 2018 is not expected to capture sea turtles, Exelon anticipates that during the post-shutdown period from December 2018 through license termination the number of sea turtles recovered at OGNGS intake structures will be so small that a requirement to evaluate the need for additional mitigation measures will not be needed. The greatly reduced intake flow rate at the OGNGS intake structures beginning in December 2018 is not expected to capture sea turtles. Even so , if a sea turtle is recovered at an OGNGS structure, Exelon agrees that notification of NMFS would be required.
However, since operation of the OGNGS would not be the cause of any reported sea turtle recovery , it should not be necessary to evaluate whether the level of turtle recoveries represents
" new information revealinQ effects of the action." No change to this term and condition is proposed beyond minor clarifying edits. Exelon agrees that this condition is appropriate as a measure for implementing RPM #3, as revised.

The OCNGS must necessary. coordinate with a qualified facility or individual to perform the necropsies on sea turtles impinged at OCNGS, prior to the incidental turtle take, so that there is no delay in performing the necropsy or obtaining the results. The necropsy results must identify, when possible, the sex of the turtle, stomach contents, and the estimated cause of death. Necropsy reports must be submitted to the NMFS Northeast Region with the annual review of incident reports or, if not yet available, within 60 days of the incidental take. REFERENCES Explanatory Comments As explained above in the Suggested Revised Text of "Reasonable and Prudent Measures" tor RPM #4, OCNGS should not be required to necropsy dead sea turtles recovered at the OCNGS intake structures because the greatly reduced OCNGS intake flow rate beginning in December 2018 is not expected to cause the death of a sea turtle. However, if recovered sea turtles are incidentally harmed by facility components or equipment, a sea turtle incident report and photographs (Appendix Ill) shall be completed by plant personnel and sent to the NMFS Section 7 Coordinator via FAX (978-281-9394}
