Docket No. 50-285 sg h

Dear Mr. Clark:

The Commission's letter dated July 10, 1981 transmitted an order confirming Omaha Public Power District's commitments for TMI-related requirements for the Fort Calhoun Station. The confirmatory order accepted District positions detailed in letters to the Commission dated December 12 and 31, 1980; January 6 and 26, 1981; and February 27, 1981.

However, additional information has been submitted on two of the tasks that modifies what was committed to in the above letters. The Dis-trict's review of the above letter also revealed that we failed te provide a schedule for completing the modifications for control room habitability requirements (Task III.D.3.4). The additional information related to these tasks is provided velow.

In response to Task I.C.1, Accident Procedures, the District's~

letter to the Commission dated December 31, 1980 committed to parti-cipate in the Combustion Engineering Owners Group (CE0G) effort. The CE0G proposed emergency procedure guidelines in response to this task have now been submitted to the Commission by letter dated June 30, 1981 (K. P. Baskin, CE0G Chairman from Southern California < Edison, to Mr.

Darrell G. Eisenhut). It is the District's understanding that upon the Commission's approval of these guidelines, they must be implemented during the first refueling outage commencing six months after Commission approval. The District expects to meet this schedule.

The EPRI program schedule for testing of safety and relief valves, Task II.D.1, has been substantially delayed. The revised valve testing schedule was provided to the Commission by the Consumers Power Company letter (R. C. Youngdahl to Mr. Harold Denton, dated July 24,1981). The District as a participant in the EPRI program endorses the revised schedule. The District also fully supports the EPRI position on block valve testing detailed in the July 24, 1981 letter.
