Sharfman, Esquire Member, Atomic Safety and Licensing Appeal Board U.S. Nuclear Regulatory Commission Washington, D.C. 20555 Re: In the Matter of the Application of Public Service Company of Oklahoma, Associated Electric Cooperative, Inc. and Western Farmers Electric Cooperative (Black Fox Station, Units 1 and 2),

Docket Nos. STN 50-556 and STN 50-557 Gentlemen:

I am enclosing a copy of a letter, dated October 19, 1979, from Applicants' Manager of the Black Fox Station Nuclear Project to the NRC Staff. Mr. Ewing's letter con-firms several conversations with the NRC Staff concerning the excavation of the foundation area for Unit 2. This work was authorized by the NRC Staff on November 30, 1978 when it issued Amendment 2 of the Limited Work Authorization for the Black Fox Station.

Overexcavation of the Unit 2 foundation area was necessary to remove certain underlying soft, siltstone material, and as Mr. Ewing's letter indicates, this material will be replaced with concrete fill to bring the excavation 1 272 7g11140 07l 9

surface up to design grade. Thus the Unit 2 structures would be supported on fill concrete founded directly on the same competent siltstone as for Unit 1.

Applicants do not believe this information has any significant relationship to the site suitability or environ-mental matters which are now pending before this Appeal Board.

However, consistent with the teachings of McGuire (Duke Power Company (William B. McGuire Nuclear Station, Units 1 and 2),

ALAB-143, 6 AEC 632 (1973)) and its progeny, we are erring on the side of full disclosure.

Applicants will send the Appeal Board and parties copies of the analyses referred to in Mr. Ewing's letter as soon as they become available.

Sincerely, C b, oseph Gallo One of the Attorneys for the Applicants cc: Appeal Board Service List 1 273
