,~ Gecumit Offices: 212 West Michigan Avenue, Jackson, Michigan 49201. Area Code 517 7G8-0550 April 3, 1975 Division of Reactor Licensing Re: Docket 50-155 US Nuclear Regulatory Commission License DPR-6 Washington, DC 20555 A0-08-75 Big Rock Point Plant Gentlemen:

By letter dated March 31, 1975, Consumers Power Company trans-mitted an Abnormal Occurrence Report for the Big Rock Point Plant. This report was numbered A0-08-75 and pertained to containment supply vent valve leakage. Subsequent review of this report has detected an error in Item 6 of the report which needs to be corrected for purposes of clarity.

The next to the last sentence in Item 6 of the report should read "The initial evaluation of this occurrence attributed the large leakage to a packing maladjustment of CV-4096 which is a check valve downstream (during DBA conditions) of CV-4097 (an air-operated butter-fly valve)."

I regret the inconvenience of this lack of clarity in the report.

Yours very truly, P-RBS/wl Ralph B. Sewell Nuclear Licensing Administrator CC: JGKeppler, USNRC
