Entergy indicated that correcting for collection efficiency due the effects of water temperature was also a complicating factor as a series of different consultants had worked for the previous plant owners and had not delivered to the previous licensees the statistical programs used, only the output of those programs. Even when Entergy attempted to correct for the zero-fill issue, inconsistencies remained. As a result, the data set Entergy submits to NRC will be based on annual reports of the Hudson River Ecological Study in the Area of Indian Point. | ==Participants:== | ||

NRC staff requested a teleconference with Entergy staff in order to request data on fish impinged at the Indian Point site. As documented in previous teleconference summaries (available at ML092570752), NRC staff had identified apparent discrepancies among data Entergy used in preparing comments on the staff draft SEIS (ML091040133) and the data Entergy initially submitted to NRC (in ML080080313, cover letter at ML080080205) that the NRC used in preparing the analysis in the draft SEIS. Summary data submitted by Entergy in response to previous teleconferences (teleconference summary at ML092570752, response at ML092810351) with the staff were up to 50% different than data submitted by Entergy that NRC staff used in preparing the draft SEIS. Entergy had indicated that the data in ML092810351 were the best data available on impingement at the site.

NRC staff requested a teleconference with Entergy staff in order to request data on fish impinged at the Indian Point site. As documented in previous teleconference summaries (available at ML092570752), NRC staff had identified apparent discrepancies among data Entergy used in preparing comments on the staff draft SEIS (ML091040133) and the data Entergy initially submitted to NRC (in ML080080313, cover letter at ML080080205) that the NRC used in preparing the analysis in the draft SEIS. Summary data submitted by Entergy in response to previous teleconferences (teleconference summary at ML092570752, response at ML092810351) with the staff were up to 50% different than data submitted by Entergy that NRC staff used in preparing the draft SEIS. Entergy had indicated that the data in ML092810351 were the best data available on impingement at the site. As a result, NRC staff requested that Entergy submit a data set similar to the data Entergy submitted prior to the NRC staffs publication of the draft SEIS containing, on a seasonal basis for all years of impingement sampling, containing this best available data.
Entergy indicated that the reason for over- or under-estimates of fish impingement in data submitted to NRC prior to the NRCs publication of the draft SEIS (in ML080080313) were a result of a zero-filling error, whereby statistical data files did not include placeholders to indicate instances where zero individuals of a given taxa had been captured during their sampling. As a result, their averaging of data resulted - most often - in higher numbers of impinged organisms than shown in annual reports.
Entergy indicated that correcting for collection efficiency due the effects of water temperature was also a complicating factor as a series of different consultants had worked for the previous plant owners and had not delivered to the previous licensees the statistical programs used, only the output of those programs. Even when Entergy attempted to correct for the zero-fill issue, inconsistencies remained. As a result, the data set Entergy submits to NRC will be based on annual reports of the Hudson River Ecological Study in the Area of Indian Point.
The replacement data file will contain impingement information by strata (seasons), year, and fish taxa. It will include 16 fish species plus blue crabs along with annual totals and the associated standard error of the estimated number of fish impinged for the annual totals. The estimated number impinged for each life stage was not reported in the annual reports and will not be provided in the replacement data file. Remaining fish species (outside of the 16) will be
included in a summed total of impinged fish recorded by strata and year. Entergy indicated that it would deliver the data to NRC by November 26th.
NRC staff indicated that this new data submission will have an effect on the schedule for final SEIS issuance. Staff will review the data when it arrives from Entergy and determine what specific effect this submission will have on the schedule for issuing the final SEIS at that time.
