Any potential discharge from ASTs will be restrained by secondary containment structures. The facility includes a drainage system which directs all liquids spilled in the yard to adjacent streets as containment for spill sources outside the main facility areas (fuel dispensing, overfills of any ASTs. ) The procedures for supervising the drainage of rainwater from secondary containment into a storm drain or open water course are as follows (including description of (a) inspection for pollutants and (b) method of valving security). Pad areas available for daily visual inspections. SECONDARY-Tertiary containment is the easily inspected fuel enclosure which contains the storage vessels. The owner/operator is aware of the requirement for secondary containment, and the fuel tanks have only partial secondary containment. Rainwater is regularly contained in enclosure, which must be emptied or allowed to evaporate. The rainwater is visually inspected for contamination from petroleum product and if so found, can be collected and removed by a waste hauler contracted to remove and haul the contaminated waste water. Describe methods of preventing soil/water contamination due to spilling and over filling The slabs upon which the ASTs sit act as an impermeable barrier to petroleum products to prevent any product from reaching the ground outside the facility. Yard size is more than adequate to contain any overfill or spilling. The ASTs share a remote/fill and overflow recapture box at the fill location to catch a small (less than 10 gal.) overfill. Fill trucks have automatic shutoffs when desired volume is reached. Fill boxes are to be closed at enclosure location when not in use, per the local AHJ. Procedures for warning vehicles entering the facility to avoid damaging above ground piping: This facility has no aboveground available piping outside of the enclosure and crash protection which could be impacted by a vehicle. There are short reaches of double wall aboveground piping from the enclosure yard to dispensers, but is protected from impact by being removed & away from vehicle access or beneath and secured to the dock. The dispenser hoses are located so as to avoid damage by vehicles. Any changes in the Facility which could expose piping should be accompanied by warning signs designed to alert vehicles to expose piping. Describe containment System design, construction materials, and volume: YES In addition to the fuel enclosure, the entire facility is designed for liquids to flow and gather in the storm drains of the facility so as to be directed to the streets and/or sites contiguous to the facility. There are two actual storm drains and other drainage openings throughout the facility, which should only be considered as "drainage" and not as storm drains. No drains connect to any sewer connection outside of this facility. An interlocking warning light, a physical barrier system, or warning signs are provided in loading/unloading areas to prevent vehicular departure before disconnect or transfer lines. N/A 36
