- Seven federally-listed threatened and endangered (T&E) species are listed within Lake County
- 63 state-listed T&E species are located within Lake County ER Discussion Items: Ecology 11
Confidential, Subject to Confidentiality Agreements For Discussion Purposes Only, Non-Disclosable Information
One Cultural Resource Survey performed for the PNPP
- No archaeological entries and no National Register of Historic Places (NRHP) eligible cultural resources are located within the PNPP property
Within the 6-mile vicinity there have been 15 cultural resource surveys documented:
- 37 NRHP sites listed and two sites are eligible
- 64 archeological sites (one site on the NRHP list and one eligible)
- 100 historic structures (29 listed on the NRHP)
- 21 cemeteries
There will be no impacts to cultural resources located within the plant vicinity ER Discussion Items: Cultural Resources 12
Confidential, Subject to Confidentiality Agreements For Discussion Purposes Only, Non-Disclosable Information
An investigative process purposely seeking new information
- Discussions with Energy Harbor and PNPP subject matter experts
- Review of permits, data or reports from the past five years, plant procedures, agency correspondence
Staying abreast of new and emerging environmental issues and concerns on an ongoing basis through:
- Nuclear industry organizations/publications
- Contact with state and federal agencies
- Review of regulatory guidance and procedures that address ongoing and emergent issues
New information is considered for significance
- Does the information present a seriously different picture than in the GEIS?
- Does the information involve a new activity or aspect that can act upon the environment in a manner or an intensity not previously recognized?
- Does the information identify an environmental issue not generically considered in the GEIS?
ER Discussion Items: New and Significant Information Review 13
Confidential, Subject to Confidentiality Agreements For Discussion Purposes Only, Non-Disclosable Information
- Examine Prior PNPP SAMAs for Continued Assessment o 25 SAMAs re-evaluated from the previous draft SAMA evaluation for PNPP
- Define Composite List for Expert Panel Review
- Expert Panel identified three (3) new PNPP specific SAMA candidates o Consider replacing relays with more rugged models to address seismic relay chatter o Install a flood barrier or curb between the direct current switchgear room and Division 2 alternating current switchgear room o Review of current HFEs used to isolate a flooding event, to identify if there are any procedure enhancements or simple modifications to improve the timing/reliability of these HFEs
- Expert Panel provides concurrence on SAMA Screening Qualitative SAMA Candidate Screening PNPP Expert Panel Suggestion, Review, and Concurrence SAMA Candidate Selection 14
- Follow the approach in NEI 05-01 for SAMA identification and screening SAMA Candidate Screening Approach
Confidential, Subject to Confidentiality Agreements For Discussion Purposes Only, Non-Disclosable Information
- Two SAMA candidates were carried forward for Phase II quantitative screening o Provide alternate cooling to the EDG Rooms. The cooling would dissipate heat generated by the Emergency Diesel Generators in the event of a loss of normal cooling o Examines upgrading/replacing the most significant relay contributors with more seismically-rugged models. This may require improved cabinet anchorage and possible cabinet replacement if the relay cabinets cannot accommodate the more rugged relays
- These SAMA candidates were evaluated and screened out based on limited risk benefit
- Through the Qualitative Screening, Expert Panel Review, and Quantitative Screening evaluations, No SAMA candidates were retained for potential implementation SAMA Candidate Quantitative Evaluation SAMA Candidate Final Assessment SAMA Candidate Selection, Contd 15
