Dear Mr. Eisenhut:

The Omaha Public Power District received the Commission's letter dated January 7,1980, regarding quality assurance requirements for diesel generator fuel oil.

Procedures in use at Fort Calhoun Station Unit No.1, as described and compared to Regulatory Guide 1.137 guidance in the attachment, will assure the quality of diesel fuel oil. The District maintains that this existing program has proven effective; thus, there is no need for changes to existing procedures.

Sincerely,
