Leak Detection Ports Ah leak detection ports were opened in order to perform the tank integrity tests in accordance with the previously referenced standards and methods. There was no detection of any liquids in any of the ports or interstitial spaces. At the time of the inspection & tanks tests, there was only a cap on the leak detection ports. The Owner/Operator was advised to install a leak detection device which would either be electronic or would be visible from the ground, if actuated. The Owner/Operator subsequently installed leak detection float devices on each tank. The leak detection devices are BJ Enterprises Leak Guard mechanical float devices, which actuate when liquid is present in the secondary containment, and is readable from the ground for visual inspections. The detector has as visual indicator of liquids in the secondary containment and requires inspection on a regular basis. This type of leak detector is only capable of detecting liquids, and not capable of differentiating between water and petroleum product. That can only be ascertained via the use of petroleum product detection sensors or physical observation of the presence of a petroleum product in the interstice. The purpose of the interstice in a secondary containment tank is to detect a leak within the primary tank. As a result of all of the tanks being clear from both product and water, it is determined that all tanks have retained their integrity, have passed the integrity tests and remain fit for continued service. The SPCC Plan, which covers this facility, would indicate that integrity testing is to occur in 20 yr increments. The next scheduled SP001 inspection/test would occur in April 2039, or if intervening events and/or conditions require action earlier. Emergency Shut Off The Emergency Shut Off switches are all located within 75 feet of the AST systems, at the South side of the contiguous building, but not less than 25 feet from the fuel dispenser. Emergency Shut Off switch is located on the West exterior wall next to the door of the facling operations building which is contiguous to the fueling operations,and is at approximately eye level. Additionally there is a"red light'emergency notification system located on the South side of the building, and which actuates where there is an event requiring immediate action, Miscellaneous: Security fencing is present, serviceable, and of adequate height. All operations, including tank tilling operations, are contained within the secured areas, which is open during regular business hours. Site personnel has positive control of entry to all locations within this facility.
