3. Spill Prevention and Containment <br />a. Aboveground Storage Tanks <br />i. Source 1 (600 -gallon used oil storage tank):. UL listed double wall steel tank. Secondary <br />storage capacity exceeds capacity of primary container and can be manually monitored through <br />visual inspection of the secondary compartment. Leak detection is provided through interstitial <br />layer leak monitoring. Tank is filled by service technicians who pump used oil from transfer <br />stations through a system of overhead pipelines; transfer quantities do not exceed 2-3 gallons. <br />Any tank overfill would be immediately known to the technician who would cease any further <br />transfer and immediately notify his supervisor. Tank is equipped with monitoring system that <br />sounds an audible alarm upon release of product from the primary tank into the secondary <br />container. To prevent overfill, tank has electronic overfill alarm that sounds when tank reaches <br />95% of capacity. This alarm would notify the person filling the tank to immediately cease this <br />activity. <br />ii. Source 2 (500 -gallon new oil storage tank): UL listed double wall steel tank. Secondary <br />storage capacity exceeds capacity of primary container and can be manually monitored through <br />visual inspection of the secondary compartment. Overflow prevention is limited to manual <br />observation of ball float measurement. Leak detection is limited to interstitial layer leak <br />monitoring. The tank is filled by an oil supplier who pumps new oil into the tank through a <br />hose/pump dispensing system.
