Bonding / Grounding: All electrical conduits and electrical equipment in the Class I Division 1 areas appear to be explosion proof or intrinsically safe with no defects. Corrosion Control Systems (Cathodic Protection) The tank is elevated 5 inches above the concrete pad and does not require cathodic protection, as it is not in contact with the ground. The area beneath the tank is open and unobstructed, making for easy visual inspections to determine whether or not there are any leaks from the tank. Off load piping does not routinely contain product and therefore does not require cathodic protection. There are no Sections of this piping that lay on the secondary containment floor and while there is minimal evidence of corrosion there are no serious signs of corrosion requiring remedial action. Leak Detection Ports All 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. There is a leak detection port to determine the presence of any fluids in the secondary containment. The leak detection port is available for using a dipstick device to ascertain any leaks into the secondary containment. Leak detection is accomplished via visual inspections of the secondary containment area at regular scheduled intervals for inspection. This type of leak detection 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 the tank being clear from both product and water, it is determined that the tank has retained its integrity, has passed the integrity tests and remains fit for continued service. The SPCC Plan, which covers this facility should indicate that integrity testing is to occur in 20 yr increments, and as such the next scheduled test would occur in October 2039, or sooner if conditions require it. Emergency Shut Off The Emergency Shut Off switch is located approximately 120 feet from the East end of the 10,000 gallon Aboveground Storage Tank for diesel fuel and the dispenser, near the glass storage area, directly East of the AST. Emergency Shut Off switch is surrounded by crash bollards, is well marked and relatively easy to locate, from the fueling operations, and is at approximately eye level.
