Oconee Nuclear Station Units 1, 2, and 3 Duke Response to NRC RCI Number FPE-1 Attachment 6 Page 1 of 2 NRC RCI Number: FPE-1 During the April 2023 environmental audit, the NRC staff reviewed Duke Energys corporate Endangered Species Procedure. This procedure applies to all Duke Energy business units, including the Oconee site. The procedure summarizes the requirements of the Endangered Species Act (ESA) and how these requirements apply to Duke Energys sites and activities. It includes checklists and protocols to ensure that Duke Energy employees and contractors adequately consider listed species before undertaking an activity that has the potential to affect such species. The procedure details how incidents should be logged and reported if a listed species is harmed. Duke Energy personnel must gather detailed information about the incident and report it to the Duke Energy wildlife team, the U.S. Fish and Wildlife Service (FWS),

National Marine Fisheries Service, and the appropriate State natural resource agency, as appropriate. Such reporting would also trigger a report to the NRC under 10 CFR 50.72(b)(2)(xi), as described in Section 3.2.12 of NUREG-1022, Rev. 3, Event Report Guidelines 10 CFR 50.72 and 50.73.

Duke Energy requires that employees and contractors complete training if they could encounter listed species or have incidents during their everyday work activities. Such trainings must be conducted by a qualified subject matter expert and should be project- or species-specific. For instance, Duke Energy has recently conducted trainings for employees and contractors on protected bats, including current and likely-to-be-listed species, such as the tricolored bat, and how Duke Energy is addressing potential impacts of its projects and activities on these species.

The trainings have addressed bat life history, seasonal distributions, habitat preferences, and how to identify suitable versus non-suitable roosting trees, among other topics.

In discussions among NRC staff and Duke Energy personnel, Duke Energy shared that it is preparing a Habitat Conservation Plan (HCP) that will include the Oconee site. The HCP will address all federally protected bats, including the Indiana bat (Myotis sodalis), northern long-eared bat (M. septentrionalis), gray bat (M. grisescens), Florida bonneted bat (Eumops floridanus), and likely-to-be-listed bats, including the tricolored bat and little brown bat (M. lucifugus). The HCP will address potential impacts to include tree trimming and cutting, grounds maintenance, and other routine operational activities at facilities such as the Oconee site. Duke Energy is also developing facility-based bat management plans as part of this effort, which would be implemented at Oconee, among other sites. Duke Energy is coordinating with the FWS in its development of the HCP. Once drafted, Duke Energy will submit the HCP, along with an Incidental Take Permit application, to the FWS for approval in accordance with ESA Section 10. Duke Energy estimates that it will receive approval by roughly 2027.

Please confirm the above information concerning Duke Energys actions to address potential impacts on federally listed species on the Oconee site.

Furthermore, the Court ruled that Duke Energy is entitled to the exemption for all of the property used in manufacturing, but property not used in manufacturing is not eligible for the exemption. However, a determination had not been made as to what portion of the property is eligible for the property tax exemption and on October 7, 2021, the Court issued a decision concluding that more evidence is needed to determine what portion of the property qualifies for the exemption and parties are conducting discovery. During the April 2023 environmental audit, Socioeconomics breakout session, and in response to information need SOC-6, Duke Energy provided an update regarding this matter and stated that: 1. Duke Energy resolved the exemption determination for tax years 2018 through 2020; 2. it was determined that Duke Energy received a reduction due to the exemption; and 3. and that there will be no reduction going forward because the state changed the law to exclude electric companies from the property tax exemption. Please confirm that Duke Energy resolved the exemption determination for tax years 2018 through 2020 and that Duke Energy received a tax reduction due to the exemption and that there will be no reduction going forward because the State of South Carolina changed the law to exclude electric companies from the property tax exemption.

a. Provide updated estimated air pollutant emissions (2020-present) from operation of permitted sources at Oconee Nuclear Station (i.e., SOx, NOx, CO, PM10, and VOCs).
b. Provide updated (2020-present) estimated greenhouse gas emissions (GHG) from operation at Oconee Nuclear Station, as provided in response to information need AQN-2. As part of the response, include:
1. a brief discussion of the sources of greenhouse gas emissions, 2.explanation why GHG emissions from combustion sources provided during the April 2023 environmental audit information need AQN-2 response were lower from what was presented in table 3.3-12 of the 2021 ER; and
3. if Duke Energy anticipates additional GHG emission sources and emissions during the SLR term.

Duke Response

a. Updated estimated air pollutant emissions for ONS is listed in the Air Emissions Summary Table provided as Document 2. The state only requires monitoring NOX emissions.
b. The Annual Greenhouse Gas Summary Table is provided as Document 3.
1. The sources of greenhouse gasses associated with the ONS facility include a 5,375 horsepower (hp) diesel generator, four 762 hp FLEX diesel generators, three 560 hp diesel generator, four diesel generators rated between 350 hp and 429.1 hp, seven generators rated between 37 hp and 135 hp, 14 diesel generators rated under 16.3 hp, one 158 hp propane generator, and two 12 hp propane generators. The Auxiliary Boiler has not been used since 2020.
2. The reason for the variance between the value reported in ONS SLR ER Table 3.3-12 and the data presented in Audit Need AQN-2 is due to conservative assumptions within the original calculation. By comparison, the information provided in Audit Need AQN-2 was calculated based on the actual diesel usage and 40 CFR Part 98 emission factors.

Tricolored Bat impact Assessment (2 pages)

Duke Energy Oconee Nuclear Station Impact Assessment for the Tricolored Bat (Perimyotis subflavus)

The U.S. Fish and Wildlife Service (USFWS) published a proposed rule to list the tricolored bat (Perimyotis subflavus) as endangered under the Endangered Species Act (ESA) in September 2022. The current known range for the tricolored bat overlaps with the ONS site (USFWS 2023).

During the spring, summer and fall - collectively referred to as the non-hibernating seasons - tricolored bats primarily roost among live and dead leaf clusters of live or recently dead deciduous hardwood trees. In the southern and northern portions of the range, tricolored bats will also roost in Spanish moss (Tillandsia usneoides) and Usnea trichodea lichen, respectively. In addition, tricolored bats have been observed roosting during summer among pine needles, eastern red cedar (Juniperus virginiana), within artificial roosts like barns, beneath porch roofs, bridges, concrete bunkers, and rarely within caves. Female tricolored bats exhibit high site fidelity, returning year after year to the same summer roosting locations. Female tricolored bats form maternity colonies and switch roost trees regularly. Males roost singly. During the winter, tricolored bats hibernate which means that they reduce their metabolic rates, body temperatures and heart rate in caves and mines; although, in the southern United States, where caves are sparse, tricolored bats often hibernate in road-associated culverts, as well as sometimes in tree cavities and abandoned water wells. Tricolored bats exhibit high site fidelity with many individuals returning year after year to the same hibernaculum.

(USFWS 2023)

Tricolored bats were identified in bat acoustic surveys conducted at the ONS site and around Lake Keowee in 2012 and 2015 (Duke 2021a). Building structures on the ONS site and forested areas surrounding the plant potentially provide suitable roosting and maternity habitat for this species. No specific assessment has been made of the extent or quality of tricolored bat habitat at the ONS site. However, given the general habitat requirements of this species, it can be conservatively assumed that suitable habitat to varying degrees is present within the large amount of forested area in the vicinity of the site as well as man-made structures at the site.

Duke Energy has implemented an environmental project review process for bats that includes desktop analysis of the activity, field assessment to identify potential habitat, acoustic surveys, application of specific avoidance measures (i.e., tree clearing/cutting outside of certain important bat life-cycle periods), and agency coordination. Duke Energy is also preparing a programmatic Habitat Conservation Plan and Incidental Take Permit application for bats that will cover the ONS site. The Incidental Take Permit is anticipated to be authorized by USFWS by 2027.

Potential impacts to the tricolored bat from the operations of ONS are discussed below:

x Mortality or injury from collisions with plant structures: Bat collisions with plant structures at nuclear power plants are not well documented but are likely to be rare. There have been no bat-related incidents documented at the ONS site or adjacent Duke Energy properties.

x Loss, degradation, or disturbance of habitat: Continued operations and any refurbishment activities that entail individual tree cutting, larger scale tree clearing, tree trimming, and any percussive activities (e.g., blasting, demolition, pile driving) during the SLR term may affect the tricolored bat. Factors that may affect and result in impacts to the species include loss of maternity roosting habitat (e.g., tree cutting and clearing, construction of laydown areas, new access roads), noise impacts, and specific incidental take of the species (e.g.,

harass, harm, pursue, kill). Impacts to hibernaculum sites (i.e., caves and mines) are not expected since these wintering habitats do not occur on the ONS site or immediately adjacent. Tree or vegetation clearing, and repair/construction activities that would potentially impact other hibernaculum sites (road-associated culverts, tree cavities and abandoned water wells) or maternity/roosting habitat for the tricolored bat would be reviewed in accordance with the environmental project review process for bats and avoidance or mitigation measures implemented, as appropriate.

x Behavioral changes from refurbishment and/or construction activities: Tricolored bats have likely already acclimated to the noise, vibration, and general human disturbances associated with site maintenance, infrastructure repairs, and other site activities. Moreover, the forested areas surrounding the ONS site likely provide more suitable habitat; hence, it is unlikely that tricolored bats would establish a colony in the man-made structures at ONS. As such, behavioral changes from refurbishment and/or construction activities to tricolored bats during the SLR term is unlikely.

Duke Energys environmental project review procedures and implementation of bat specific BMPs will greatly reduce impacts to the tricolored bat. As such, the continued operation of the ONS site for the proposed operating term MAY AFFECT BUT IS NOT LIKELY TO ADVERSLY AFFECT the tricolored bat.
