1 NMFS PRD Questions related to Entergys 7/23/12 sturgeon report Entergys Response #2 10 October 2012 Entergy provided responses to NMFS PRD Questions following a conference call on 12 September 2012 attached to an email from Dara Gray to Mike Wentzel of NRC dated 27 September 2012. There were two questions that were not completely answered at that time, and this Response #2 repeats those previously unanswered questions and completes Entergys responses by providing the remaining information. Each of the two NMFS questions is shown in yellow highlight followed by Entergys response #2 answer in blue text.
2nd part of my new question - because this includes cooling and service water does it include water withdrawn through the IP1 intake?].
The historic (1976-1990) impingement density estimates were not based on Unit 1 flows because that flow was not sampled to determine impingement abundance. Impingement density was estimated separately for Unit 2 and Unit 3. For each unit, impingement density was estimated by dividing the estimated number impinged (adjusted for collection efficiency) by the intake flow derived from the sum of circulating water flow plus the service water flow.
Projections of sturgeon impingement numbers for current (2001-2008) conditions included Unit 1 intake flows. Atlantic sturgeon (Figure 3) and shortnose sturgeon (Figure 9) average impingement numbers per month were calculated as the product of average monthly impingement density times the average intake monthly flow. Actual intake flows (2001-2008 average) were obtained from Section 2.4.2.3.2 of Indian Points Alternative Technology (Enercon, February 2010) and used to represent the average monthly Unit 2 and Unit 3 flows. Specifically, the average historic (2001-2008) monthly intake flow rate in millions of gallons per day (MGD) for Unit 2 included the circulating water, service water and Unit 1 river water withdrawn from the Hudson River (Table 2.1 of Enercon, February 2010). For Unit 3, the average historic (2001-2008) monthly intake flow rate in MGD included the circulating water and service water (Table 2.2 of Enercon, February 2010).

[NMFS additional question - can you give us a zoomed in picture for the last 10 years (i.e., adjust the scale of the graph ) or provide the estimates that are on the vertical axis in a table by year? Also, is it possible to take these estimates out through 2011? We see having these abundance estimates as possibly a powerful piece of information when conducting our jeopardy analysis (i.e., being able to compare the expected number of impingements to an abundance estimate).
The table below provides the most recent ten years of sturgeon abundance projections, by species, that were plotted on the Y-axis in Figures 13 and 16 of Entergys 23 July 2012 Sturgeon Report. We have not yet calculated these estimates for 2008 through 2011.
Annual estimates of Hudson River Atlantic sturgeon or shortnose sturgeon for 1998 through 2007 based on standing crop estimates for the Long River Survey (LRS) or Fall Shoals Survey (FSS) sampling programs and published population abundance estimates from mark-recapture studies.
