Dear Mr. Muller:

This is in reference to your draft environmental impact statenent entitled " Construction o. Skagit/Hanford Nuclear Project." The enclosed comments from the Natio ,al Oceanic and Atmospheric Administration are forwarded for your con' ideration.

Thank you for giving us an opportunity to provide these connents, which we hope will ta of assistance to you. We would appreciate receiving four copies of the final environmental impact statement.

Sincerely, iAd Joyce M. Wood 0"]bik, f

SUBJECT:

DEIS 8205.04 - Construction of Skagit/Hanford Nuclear Project, (fluclear Regulatory Commission)

This office has reviewed the subject DEIS, and we offer the following specific comments:

Specific Comments Paj]e 4-12, paragraph 2. The proposed water inlet opening size does not meet NMFS criteria for the protection of juvenile anadromous fish at intake structures.

Page 4-57, paragraph 4. Perforation diameters for the intake structure do not meet NMFS criteria for the protection of juvenile anadromous fish.

Page 4 Thennal discharges. The discussion should include an estimate of the ranges of actual temperatures which might result from the cases presented. The temperature resulting from the introduction of 29.2 C effluent into river water at 20 C contrasts sharply with temperatures produced by introducing 20.5 C effluent into river water at 10.8 C or 3.9 C.

Pages 4-60 to 4-62. Figures 4.19, 4.20 and 4.21 need more explanation. It is not clear from either the captions or the text what the figures represent or which cases they are intended to illustrate.

Page 4-63, paragraph 2. Even when juvenile fish manage to avoid exposure l to elevated temperatures which can induce loss of equilibrium and result in increased predation, the avoidance activity itself may trigger predation.

Page 5-16. We concur with the recommendation that a program to monitor site habitat alteration and recovery time he instituted.

Page 5-18, paragraph 2. We suggest that the thermal plume area be monitored l

for predation rate under operational conditions during the downstream

! migration period. This would document the losses, or perhaps lack of impact attributable to thermal effect on juvenile salmonids.
