3c - CG TRACENPETINST 10340.0 A - Monitoring Plan for Gasoline Dispensing Facility.pdf

This is a Monitoring Plan for a Gasoline Dispensing Facility at the United States Coast Guard Training Center Petaluma in California, issued as Coast Guard Training Center Instruction 10340.0 A in October 2005.

The plan establishes comprehensive procedures for monitoring and maintaining underground storage tanks (USTs) containing 10,000 gallons of gasoline each to ensure compliance with federal, state, and local regulations, including 40 CFR 280 and California Code of Regulations Title 23, Division 3, Chapter 16. The facility utilizes a Veeder-Root TLS-350 electronic leak detection system with continuous 24-hour monitoring of tank annular spaces and piping, supplemented by daily inventory reconciliation. Key monitoring requirements include daily level comparisons using tank level printouts, monthly inventory reconciliation with an allowable variation of 1.0 percent of total monthly input plus 130 gallons, and immediate notification procedures when variations exceed acceptable limits. Designated personnel—Gas Station Attendants, Gas Station Supervisors, the CGES Manager, Chief of Motor Pool, and the Chief of Environmental Section—have specific responsibilities for alarm response, inventory calculations, and regulatory notifications. The plan mandates annual preventive maintenance and testing of all monitoring equipment (Tank Level Sensing System, Tank Leak Detection System, and Piping Leak Detection System) during July, plus annual dispenser meter calibration by the County's Department of Weights and Measures. Records must be retained for specified periods ranging from 3 to 6.5 years, with five-year retention for inventory reconciliation data. Training requirements are established for all personnel involved in facility operations, with the Environmental Protection Specialist and Chief of Motor Pool required to obtain UST-California certification through the International Code Council examination.
