OF TELEPHONE CONFERENCE CALL HELD ON MARCH 21, 2011, BElWEEN THE U.S. NUCLEAR REGULATORY COMMISSION AND NEXTERA ENERGY SEABROOK, LLC, TO CLARIFY THE RESPONSES TO THE REQUEST FOR ADDITIONAL INFORMATION PERTAINING TO THE ENVIRONMENTAL REVIEW OF THE SEABROOK STATION LICENSE RENEWAL APPLICATION (TAC NO. ME3959)

The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of NextEra Energy Seabrook, LLC (NextEra or the applicant), held a telephone conference call on March 21, 2011, to clarify information in the applicant's responses to the staff's requests for additional information (RAls) concerning the environmental review of the Seabrook Station license renewal application (LRA). The telephone conference call was useful in clarifying the information provided in NextEra's RAI responses. provides a listing of the participants and Enclosure 2 contains a list of issues sent to the applicant prior to the phone call to facilitate preparation for the phone call, including a brief description on the status of each item.

The applicant had an opportunity to comment on this summary.

Aquatic Ecology Clarifications for Seabrook Station

1. Clarify whether blank cells within Table 4-6 of NAI (2010) should be treated as "0" (e.g.

Seabrook collected samples, but did not identify any fish of the particular species), as suggested by EPA (2002).

Discussion: The applicant clarified that blank cells within Table 4-6 of NAI (2010) should be treated as "0."

2. Clarify why NAI (2010) (Table 4-6) and NextEra's response to RAI #2 (for aquatic ecology) report different entrainment estimates for Atlantic cod, cunner, fourbeard rockling, goosefish, lumpfish, and winter flounder than U.S. Environmental Protection Agency (EPA) (2002)

(Table G3-6) from 1990-1998. Entrainment estimates for other species were similar among NAI (2010) and EPA (2002), as long as blank cells in Table 4-6 (NAI 2010) are treated as "0."

Discussion: The applicant explained that in the response to the staff's RAls, egg entrainment estimates for Atlantic cod included portions of the following categories: Atlantic cod, Atlantic cod/haddock, and Gadidaelwitch flounder.

NextEra assured the NRC that the data provided to EPA was the same entrainment data from 1990-1998, which is described in NextEra's environmental monitoring report from 2009 (NAI2010). NextEra felt it was inappropriate to speculate how EPA used the data provided in Seabrook monitoring reports to determine entrainment rates in EPA (2002). After EPA published its case study (EPA 2002), the applicant sent comments to EPA stating that EPA seemed to combine numerous species under a single species category (North Atlantic 2002).

Additional Information: In EPA's response to the applicant's comment, EPA stated that its methodology, "used species aggregation to reduce the total number of distinct species requiring individual parameter sets because of the lack of life history data for many species, particularly survival rates of early life stages. EPA believes that the aggregations are reasonable and do not introduce significant biases." (EPA 2004 a).

3. Clarify why NAI (2010) (Appendix Table 4-3) report different impingement estimates for Atlantic cod, Atlantic herring, fourbeard rocking, lumpfish, red hake, sculpin spp., killifish, threespine stickleback, windowpane, and winter flounder than EPA (2002) (Table G3-2) from 1994-1998. Impingement estimates for other species were the same among NAI (2010) and EPA (2002).

Discussion: The applicant assured the NRC that the data provided to EPA was the same impingement data from 1994-1998, which is described in NextEra's environmental monitoring report from 2009 (NAI2010). NextEra felt it was inappropriate to speculate how EPA used the data provided in Seabrook monitoring reports to determine impingement rates in EPA (2002). After EPA published its case study (EPA 2002), the applicant sent comments to EPA stating that EPA seemed to combine numerous species under a single species category (North Atlantic 2002). In addition, the applicant noted in its comments to EPA that EPA (2002) reported numerical errors for impingement estimates of Atlantic cod, fourbeard rockling, and threespine stickleback (North Atlantic 2002).
