Mr. Daniel R. Muller Assistant Director Environmental Projects Division of Reactor Licensing U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Muller:

BOARD MEMBEP.S Ray W. Edwards Chairman Andrew W. McThen;a, Jr. Vi~-Chairman J. Leo Bourassa Warren L Braun Denis J. Brion Basil T. Carmody Mrs. Wayne Jackson This is in reference to the Virginia Electric & Power Company (VEPCO) - Surry Nuclear Power Plant and the cooling water dis-charge temperature limitation imposed by the technical.speci-fications of the U.S. Nuclear Regulatory Commission. The Commonweal th of Virginia State *water Control Board (Board) and the Environmental Protection Agency (EPA), have issued a joint National Pollutant Discharge Elimination System (NPDES) permit to the Surry Nuclear Power Plant. This permit includes a heat rejection effluent limitation for the condenser cooling water.* It was believed at the time the permit was issued that the heat rejection limitation would maintain the Virginia Water Quality Standards. To insure these standards would be maintained a special condition was included in the permit regarding environmental studies to be conducted. This special condition required the permittee to collect data that would enable EPA and the Board to determine if the Water Quality siandards were being complied with. The special condition further required that the perrnittee furnish a recommendation for the appropriate mixing zone size to be assigned to the J?lant~ .On August 6, 1975, the Board received preliminary temperature profiles of the James River submitted by VEPCO relative to the Surry Plant. The Board has made an evaluation of this d~ta and has concluded that the ambient standard adopted by Attachment No. 5 Page 1 of 2

.. J... Mr. Daniel R. Muller Page Two August*?, 1975 the Board is being maintained. *.Also, based on this preliminary information, it would seem that the temporary discharges in-volving temperatures exceeding 98°F did not result in the temperature water quality standard being 'violated.

Hoviever, it is emphasized that these conclusions are not final and may be revised as additional data becomes available.

On the basis of the foregoing analysis, we do not object to your agency granting a temporary waiver from the 98° specifications. However, if a temporary waiver is approved, we request that it be amended to require VEPCO to develop and obtain the Board's staff approval of a continuous monitoring program. We believe that the monitoring program as developed for the 316(b) study will be adequate for this purpose. It is emphasized-that the temporary *waiver, if granted, does not auth_orize the Surry Plant to violate the jointly issued NPDES permit or the Water Quality Standards. /cs Sincerely yours, E::r;:nserr~~ Executive Secretary Attachment No. 5 Page 2 of 2
