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

This is a Monitoring Plan instruction document for the United States Coast Guard Training Center Petaluma that establishes requirements for monitoring and maintaining the facility's underground gasoline storage tanks (UST) and associated dispensing system.

The plan mandates comprehensive monitoring protocols to ensure compliance with federal regulations (40 CFR 280), California Code of Regulations (Title 23, Division 3, Chapter 16), and Coast Guard policy per COMDTINST M5090.9. The gasoline dispensing facility operates two 10,000-gallon underground storage tanks with double-walled construction, fiberglass-reinforced plastic cladding, and pressurized piping. The system includes continuous 24-hour electronic leak detection via Veeder-Root TLS-350 equipment for both tank annular spaces and piping sumps. Monitoring activities include daily inventory reconciliation comparing calculated usage against physically measured tank levels, with an allowable monthly variation of 1.0 percent of total monthly input plus 130 gallons. If daily variations exceed 6 gallons or monthly variations exceed the allowable threshold, escalating corrective actions are required, including notifications to the Chief of Motor Pool, CGES Manager, Environmental Section, and potentially county authorities if unauthorized releases are confirmed. The plan specifies responsibilities for Gas Station Attendants, Supervisors, CGES Manager, Chief of Motor Pool, and Environmental Protection Specialists, along with required annual maintenance testing of monitoring equipment in July, quarterly cathodic protection system testing, and annual dispenser meter calibration by county authorities. Record retention requirements range from 3 to 6.5 years depending on document type, with training required for all personnel involved in facility operations.
