Audit Needs AQ-1 ER, Revision 1, Section 2.2.3.1 states: Modeling studies presented by the U.S.
Atomic Energy Commission and the NRC in the operating stage final environmental statements indicate that under typical conditions, the areas of the thermal plumes to the 2° F isotherm (above ambient) from the St. Lucie Units 1 and 2 diffusers would be approximately 180 acres and 75 acres, respectively. Please provide the area of the thermal plume under current (i.e., post-extended power uprate (EPU)) operating conditions.
AQ-2 ER, Revision 1, Sections 3.7.7.1.1 and 4.6.1.4 describe an impingement study conducted for Unit 1 from 1976-1978. Have any more recent impingement studies been conducted at St. Lucie? If so, please provide copies of these studies for NRC staff review.
AQ-3 The NRCs 2003 final supplemental environmental impact statement for license renewal of St. Lucie (NUREG-1437, Supplement 11, p. 4-11) states the following.
Pursuant to a special condition of the St. Lucie Unit 2 site certification issued by the Florida Department of Environmental Protection (FDEP) in compliance with Florida law (FDEP 1976), a mitigation program was implemented whereby Florida Power
and Light Company (FPL) periodically traps fish from the intake canal, tags them, and releases them in the ocean. This program is carried out at the behest of the Florida Fish and Wildlife Conservation Commission (FFWCC). Although the special condition specified that this mitigation take place during construction of St. Lucie Unit 2, FPL has continued the program beyond the construction period. Collections are made on a quarterly to a monthly basis, with a goal of tagging and releasing 1000 fish per year. FPL cooperates with various institutions to provide specimens for display and research.
Does FPL still implement this mitigation program? Does FPL intend to continue this program during the proposed subsequent license renewal term?

Audit Needs
SAMA-1 In the ER, FPL indicated that it is following the guidance in Nuclear Energy Institute (NEI) 17-04, Model SLR New and Significant Assessment Approach for SAMA, Revision 1, for providing SAMA new and significant information. NEI 17-04 specifies, Further documentation of the new and significant information review is listed in Section 3.5.2. Furthermore NEI 17-04 indicates, Such documentation should be available to the NRC [U.S. Nuclear Regulatory Commission] either in the SLR [Subsequent License Renewal] ER (at the SLR applicant's discretion), or in supplemental information for review via E-document reading room, audit, and RAIs [requests for additional information].
Specifically, the staff would like to briefly discuss the probabilistic risk assessment (PRA) revisions and changes to the risk models since the 40-to year license renewal application (focusing on changes made at the plant that have significantly reduced or increased risk).
SAMA-2 NEI 17-04 Section 3.1 Data Collection specifies:
Use the latest risk models that are available for internal events (including internal flooding) and for each of the external events contributors identified for evaluation in NEI 05-01 [Severe Accident Mitigation Alternatives (SAMA) Analysis Guidance Document, Revision A, November 2005].
NEI 05-01 specifies:
The IPEEE [Individual Plant Examination of External Events] identified the highest risk externally initiated accident sequences and potential means of reducing the risk posed by those sequences. Typically, the following external events were evaluated:
- Internal fires
- Seismic events
- Other external events such as high wind events, external flooding, transportation and nearby facility accidents Explain how Other external events such as high wind events, external flooding, transportation and nearby facility accidents were considered in the PSL SAMA New and Significant Evaluation? Discuss options considered to reduce risk due to each of these external events.
SAMA-3 Were there any St. Lucie or other facility external event SAMAs evaluated? If so, briefly describe. If not, indicate the reason why not.
SAMA-4 The NRC approved an 11.85 percent power uprate for both St. Lucie units 1 and 2 in 2012. It is stated in Section 4.15.2 of the FPL ER that:
As part of the uprate, FPL implemented some plant changes to offset any potential increase in core damage frequency (CDF) and large, early release frequency (LERF), and ultimately reduced the CDF and LERF compared to pre- EPU values.
and:
In addition, since the EPU, the PRA was updated to include impacts related to the EPU, so the effects of the EPU are also included in the quantitative SLR SAMA evaluations.
Table E-14 of the 2013 Generic Environmental Impact Statement (GEIS) presents the change in LERF calculated by each licensee that has been granted a power uprate of greater than 10 percent. Table E-14 shows that the increase in LERF ranges from a minimal impact to an increase of about 30 percent (with a mean of 10.5 percent). Please provide the specific CDF and LERF values to confirm values are within the values calculated in the GEIS. Also, be prepared to discuss the plant changes and the PRA updates as related to the 2012 EPU.
SAMA-5 Section 4.15.3 of the FPL ER provides a summary of the information assessed for new and significant information. Did FPL evaluate all the items in the 2013 GEIS SAMA Summary Table E-19 (including low power, uncertainties, and the BEIR Report)?
SAMA-6 Please be prepared to briefly discuss the population increase as it relates to being within the values evaluated in the GEIS Document Needs None Socioeconomics (Nancy Martinez)
Audit Needs SOC-1 Table 3.9-2 of the ER provides FPLs annual property tax payments for 2015 through 2019. Please provide FPLs property tax payments for St. Lucie for 2020 and 2021, if available.

- b. Please describe the mowing/cutting practices and herbicide use in the right-of-ways. What practices are used to avoid impacting protected species when maintaining the right-of-ways?
- c. What is the impact of the new transmission lines and towers or power lines on bird collisions?
TER-2 Section 3.7.8.5 in the ER states, Currently, FPL maintains a migratory bird special purpose utility permit which involves the tracking and uploading of data for handling of any injured or deceased bird found within the PSL site. Injured birds are transported to rehab facilities when feasible. A yearly report is submitted to USFWS to maintain compliance with federal regulations.
- a. Please provide a copy of the migratory bird special purpose utility permit MB697722-0.
- b. Please provide the yearly reports submitted to the USFWS for the past 10 years.
TER-3 The ER cites extensively the 2001 Foster and Wheeler survey, St. Lucie Power Plant and Transmission Line, Threatened and Endangered Species Survey.
Have any surveys or studies on State protected species or species protected under the Migratory Bird Treaty Act or Bald and Golden Eagle Protection Act been conducted since 2001 by either FPL or another entity? Please provide any known avian or terrestrial ecology studies performed in the last 10 years.
Document Needs None Waste Management (rad and non-rad) (Phyllis Clark)
Audit Needs WM-1 If there have been any reportable unplanned releases of radioactive materials (unplanned/inadvertent radioactive liquid or gaseous releases) which would trigger a notification requirement since the ER was written, please provide a description of the releases. Please be prepared to discuss your plan to handle unplanned releases of radioactive materials.
WM-2 If there have been any reportable inadvertent nonradioactive releases that would be classified as an incidental spill which would trigger a notification requirement since the ER was written, please provide a description of spills/releases. Please be prepared to discuss your plan to handle inadvertent nonradioactive releases.
WM-3 St. Lucie is subject to the reporting provisions of 40 CFR Part 110 as it relates to the discharge of oil in such quantities as may be harmful pursuant to Section 311(b)(4) of the Federal Water Pollution Control Act. Any discharges of oil in such quantities that may be harmful to the public health or welfare or the environment must be reported to Environmental Protection Agencys National Response Center. In section 9.5.3.7 of the ER, the applicant discusses reportable spills and states that for the 5-year period of 2016-2020, there were no reportable spills/no releases. If there have been any reportable spills/releases which would trigger this notification requirement since the ER was written, please provide a description of any spills/releases.
WM-4 St. Lucie is subject to the reporting provision under Florida Administrative Code 62-780 and under the site conditions of certification. This reporting provision requires that any spills of materials having potential to significantly pollute surface or groundwaters and which are not confined to a building or similar containment structure be reported to the FDEP Office of Emergency Response by telephone immediately after discovery of such spill, followed by a detailed written report.
Section 9.5.3.8 of the ER states that between the 5-year period of 2016 to 2020, there has been one release at St. Lucie that triggered the notification requirement (on October 22, 2019). The ER states that the spill was attributed to a lift pump station at the north lift station which experienced failure, allowing approximately 400 gallons of untreated domestic wastewater to overflow the sump and collect on the surrounding grass, with some of the water draining onto adjacent concrete and through a drainage culvert into the intake canal. Wastewater that had pooled on the ground was removed, but water that reached the canal was unrecoverable. The ER states that St. Lucie replaced the lift pump indicators and audio, and visual level indication was entered into the work week process for repairs. An evaluation of the remaining lift pump stations at the site was also conducted and no other issues were noted. The ER also states that the FDEP waived the requirement of a formal report, and notification of the spill to the NRC was not required.
Please explain why the FDEP waived the requirement of a formal report, and why notification of the spill to the NRC was not required. In addition, if there have been any reportable spills which would trigger this notification requirement since the ER was written, please provide a description of any spills/releases.
WM-5 Licensees are required to consider pollution prevention measures as dictated by the Pollution Prevention Act (Public Law 101 5084) and the Resource Conservation and Recovery Act of 1976, as amended (Public Law 94 580). The Resource Conservation and Recovery Act (RCRA) governs the disposal of solid waste. In addition, in accordance with the RCRA Section 3002(b) and 40 CFR 262.27, a small or large quantity generator must certify that a waste minimization program is in place to reduce the volume and toxicity of the waste generated to the degree determined to be economically practical.
The ER states that St. Lucie is meeting this requirement as procedural measures are in place to minimize hazardous waste generated to the maximum extent practical.
Please provide the specific procedural measures referred to in Section 9.5.13.
Document Needs:
WM-6 Provide procedures related to the radioactive and nonradioactive Waste Management Program, Waste Minimization Program, and Stormwater Pollution Prevention Plan.
WM-7 Drawings and photos that are highlighted/marked showing the flow paths for releases and rad and non-rad waste paths. Please have St. Lucie subject matter experts available to discuss the flow paths.

Document Needs None Water Resource - Surface Water (Lifeng Guo/Nancy Martinez/Kevin Folk)
Audit Needs SW-1 Clarify discrepancy on the number of outfalls. The ER states the current National Pollutant Discharge Elimination System (NPDES) permit authorizes discharges from four outfalls (Sec. 3.6.1.2.1). But Table 3.6-1 lists five outfalls. St. Lucies revised FPL industrial wastewater facility permit (IWFP)/NPDES permit approved on May 21, 2020 expired in November 2021. Clarify whether FPL has filled to renew the NPDES permit (FDEP, 2002b) (ER Sections 3.6.1.2.2 and 9.5.3.3, Table 6.1).
SW-2 Provide an update to St. Lucies surface water withdrawal summary to include data for calendar year 2021 (ER Section 3.6.3.1, and Table 3.6-3b).
SW-3 The ER summarizes historical regulatory infractions including notices of violation issued to FPL for the period 2016-2020 (ER Sections 3.6.1.2.5, 9.5). As applicable, provide an updated summary of and describe any Notices of Violation; nonconformance notifications; or related infractions received from regulatory agencies associated with permitted effluent discharges, sanitary sewage systems, groundwater or soil contamination, as well as any involving spills, leaks, and other inadvertent releases (e.g., petroleum products, chemicals, or radionuclides) received since 2020. In addition, summarize any self-reported IWFP/NPDES permit infractions since end of 2020 (i.e., including any disclosed in Discharge Monitoring Reports). Provide copies of relevant correspondence to and from the responsible regulatory agencies.
SW-4 The ER states that the recent dredging of the intake canal was performed in 2019.
Provide a brief assessment of future need of dredging to remove sediment build-up in the vicinity of the intake and discharge during the license renewal period (ER Section 3.6.1.2.4).
SW-5 Clarify the nominal capacity of the eight circulating water pumps and the three intake cooling water systems described in ER Section 2.2.3.
Document Needs SW-6 Renewal application for IWFP/NPDES permit No. FL0002208 (ER Section 3.6.1.2.1, and 9.5.3.3).
SW-7 The operating agreement between the FDEP and participating agencies identifies the final order issued as part of the power plant siting act as the 401 Certification for St. Lucie power plant (PA 74-02, issued 09/17/2008) (ER Section 9.5.3.2).
