Dear Mr. Crisp:

PROJECT NO. 6335-VA NORTH ANNA HYDROELECTRIC PROJECT STATEMENT _ OF DAM OPERABILITY TESTS Pursuant to the provisions of 18 CFR 12.44(b)(2), the annual statement is j

hereby submitted ve-ifying that each spillway gate has been operated at least once during the twelve months preceding the annual inspection by the FERC Regional Engineer.

The last annual inspection was conducted by Mr. J. C. Lyon, Jr. on August 24,1995. As required by 18 CFR 12.44(c)(1), the annual statement describing the intervals at which the standby emergency power was load tested during the year preceding the inspection is also provided. During 1995, the main dam spillway emergency diesel generator was load tested on a monthly basis in accordance with approved station procedures. Verification of this information is provided on the attached form in accordance with 18 CFR 12.13.

The main dam's five spillway gates (three radial gates and two skimmer gates) were satisfactorily tested from their full open to full close positions between June 21,1995, and July 12,1995, as specified on the attached form. The gates' stop legs were in place during the performance of these tests.

Satisfactory operation of one spillway gate using power supplied by the spillway's emergency diesel generator was observed by Mr. Lyon during the August 24,1995 inspection.

If you have any questions, please contact us.

Very truly yours, I
