Dear Mr. Miraglia:

[gf- _

This is in reply to your letter, dated 8 May 1981, to Mr. Bruce Barrett, US Department of Commerce, requesting review and comments on the Draft Environmental Statement (DES) related to rhe opera- ,

tion of the Waterford Steam Electric-Station, Unit No. 3.

We have reviewed the document in accordance with our areas of respon-sibility and expertise as outlined in the Council on Environmental Quality Regulations, Title 49, CFR, Part 1500, published in the

" Federal Register" dated 29 November 1978; and US Army Corps of Engi-neers administrative procedures for permit activities in navigable waters or ocean waters, Title 33, CFR, Parts 320-329, published in 1 the " Federal Register" dated 19 July 1977.

1 We have the following comments to offer:

a. The effect of plant operati.v -n water temperatures is dis- m cussed in Section 4.2.2.2 (page 4-3). '..he effect of these increased temperatures on reactor coolant chemicals (Section 4.2.4.1, page 4-10),

however, is not discussed. Temperature changes influence river pH and alkalinity through shifts in the chemical equilibria of carbonate, sul-fate, borate, and phosphate. Changes in D0 and additions of boron and sulfates (Table 4.3) further complicate the situation. The carbonate equilibrium is particularly important since CO2 levels help determine the degree of eutrophication and the health of aquatic animals. The impact of Waterford 3 on pH and alkalinity along with the resulting s changes in the chemical equilibria should be fully discussed in this DES.

b. In Table 1.1, the US Army Corps of Engineers permit is dated 4/77. According to our records, this should be 9/77.

Thank you for the opportunity to review and comment on this DES.

Sincerely,
