Spill Prevention,Control,and Countermeasure Plan Love's/Speedco#944,Ripon,California Page 8of13 anteagroup The California Governor's Office of Emergency Response and the local administrative agency (Central Valley Regional Water Quality Board) must be notified of any petroleum discharge which creates a visible sheen on a navigable surface water body or any discharge to a surface water which exceeds a quantity of 42 gallons. 4.11 Potential Spill Predictions of Direction, Rate of Flow,and Quantities [40 CFR 112.7(b)] The facility's record of no reportable spill occurrences within the previous 5 years is considered an indication that a reasonable potential for equipment failure does not currently exist at the facility. Potential spill predictions for the fueling station are discussed below.Additional information is presented in Table 1. • Five (5)ASTs are located within the interior of the Facility and within a secondary containment structure. Tanks 1 through 4 have capacities of 7,846 gallons each, and Tank 5 has a capacity of 5,800 gallons. The ASTs are constructed of welded steel and are compatible with their contents. The tanks are painted and were constructed in 2006. Each tank is oriented vertically and situated on steel skid supports.The product is stored in this area and is subsequently transferred to the dispensing units in the lubrication bays by underground pipelines in a concrete trench. Product delivery occurs by tank truck deliveries to three fill ports that are located at an interior wall adjacent to Lubrication Bay#3.The potential for a spill exists with a ruptured delivery hose, tank overfill, or a tank failure. The secondary containment structure has a holding capacity of approximately 11,420-gallons. A spill up to approximately 11,420 gallons would remain within the secondary containment basin. A spill exceeding 11,420 gallons that would overflow the secondary containment basin will flow toward the floor drains and to the sump. A spill kit is located in the immediate vicinity of the containment area. Visual inspection of ASTs, oversight of deliveries, visual gauges, and proximity of spill clean-up materials are some of the applicable discharge prevention measures. • A potential spill could take place within the transfer area of the lubrication bay. If an accidental overfill takes place during delivery or extraction, approximately 250-gallons could be spilled (based on estimated 5 minute overfill time). Any spill would be directed to floor drains, which lead to the sump, to the oil/water separator, and to the used oil tank. Visual inspection of ASTs, oversight of deliveries, visual gauges, and proximity of spill clean-up materials are some of the applicable discharge prevention measures. • A third potential spill could occur in the lubrication bay area storing diesel fuel which is used for the lubrication of fuel filters prior to their installation on vehicles. The product is delivered by tanker and transferred directly into the tanks. The ASTs are constructed of welded steel and are compatible with their contents. The tanks are painted. Tank failure or accidental overfill are potential means of spills within this area. The ASTs are located within the interior of the Facility. The tanks are situated on a concrete floor next to floor drains, which leads to the sump, to the oil/water separator, and to the used oil tank. Visual inspection of equipment, supervised transfers, visual gauges, and proximity of spill clean- up materials are applicable discharge prevention measures. Procedures for dealing with leaks are listed in Section 4.6. 4.12 General Containment/Diversion Controls [40 CFR 112.7(c)] At a minimum, the facility is required to employ one of the containment/diversionary structures or equipment listed in §112.7(c)for each oil container shown in Table 1 to prevent discharges of oil into navigable waters. Table 1 lists general secondary containment provisions for all applicable oil storage containers.
