OFFSITE NOTIFICATION DUE TO DIESEL FUEL SPILL ONSITE
The licensee notified the Maine Department of Environmental Protection regarding the spillage of approximately 25 gallons of diesel fuel. The fuel oil was spilled when the fuel tank of a truck was punctured as it was driving over a temporary ramp. The spill has been contained.

10 CFR 21 REPORT - POTENTIAL FOR MAJOR DEGRADATION OF SAFETY EQUIPMENT
The following is from a faxed report:
"Basic component: Safety-related terminal block (symbol #95-10-077)
"Supplier: Systems Control of Iron Mountain, Michigan [manufacturer is General Electric, both supplier and manufacturer have been contacted by NMP.]
"Nature of defect: While installing a new terminal block in the emergency diesel generator panels, a mounting screw for terminal points was found to be loose. Contrary to general quality requirements stated in the Purchase Order, this screw was not fully threaded during manufacture. As a result, if installed, the screw could potentially have fallen into safety-related equipment located below thereby potentially affecting the function of the emergency diesels. Thus, a major degradation of essential safety-related equipment ,i.e., a substantial safety hazard, could have occurred.
"Number of terminal blocks initially estimated to be affected at Nine Mile Point Units 1 and 2: Several hundred (including 169 in stock)
"Corrective actions taken: The defective terminal block was discarded, A 20 percent sample inspection of the terminal blocks remaining in stock at NMP was performed. No other loose screws were identified. These terminal blocks were supplied in the 1980s and no plant operational problems due to a loose screw in a terminal block were previously identified. Therefore, it has been concluded that this is an isolated instance.
"Date of discovery: May 14, 2001
"Date on which 10CFR21 evaluation completed: July 12, 2001
"Date on which Vice President Nuclear Generation notified: July 17, 2001
"Date by which written 10CFR21 report will be submitted: August 16, 2001
The licensee notified the NRC Resident Inspector.
