Mine <br />2004 SPCC <br />• 4.3 SHOP/WAREHOUSE BULK OIL STORAGE <br />The Shop/Wazehouse Bulk Oil Storage facility is identified on Figure 2. 6,500 gallons of oil <br />products (containers #9-#11) are stored at the south end of the Shop/Wazehouse inside the <br />building. The tanks rest inside a concrete block below grade vault and sit on a concrete floor. <br />Outside the building on the south end there aze two additional tanks (labeled #12 and #13)--one <br />containing kerosene (300 gallons) and the other containing solvent (500 gallons). Both these <br />tanks sit on elevated metal frame stands and rest on a concrete slab. In addition, inside the south <br />end of the wazehouse there aze thirteen (13) 55 gallon drums of oil and grease products (labeled <br />#14 on Figure 1). The number of drums at location #14 may be increased to 30, if needed. <br />4.3.1 Oil Inventory <br />Up to 9,000 gallons (containers #9-#13 plus a full contingent of 30 drums) of oil products aze <br />potentially stored in the Shop/Wazehouse Bulk Oil Storage facility. Table 1 describes in detail <br />the containers and contents of each container at the Shop/Wazehouse facility. <br />4.3.2 Containment and Diversionary Structures <br />The concrete block vault surrounding tanks #9-#11 provides 10,500 gallons of containment, <br />which is enough to hold the contents of the largest container plus an allowance for stormwater in <br />the event of a spill. Tanks #12 and #13 have secondary containment consisting of the concrete <br />slab and a sump that eventually reports to the industrial water pond. In the unlikely event of a <br />spill, the oil would be routed into the industrial water pond where the oil would be trapped by a <br />sorbent boom at the inlet end. The detention time and surface area on the inlet side of the <br />confinement boom allow the petroleum effluent to accumulate behind the boom, where it can be <br />pumped off and disposed o£ Spills of any of the drums would either report directly to the floor <br />of the building or the concrete slab and sump system described above. <br />If any of the above tanks and the secondary containments (vault or industrial water pond) were to <br />rupture, the oil products could still be contained by downstream CDPS basins. <br />4.3.3 Conformance with Applicable Requirements <br />The tanks at the south end of the Shop/Wazehouse appeaz to be in good condition, based on field <br />inspections of May 6, 2004. The overall housekeeping effort was observed to be good during the <br />site inspections. Applicable state guidelines are assumed to be the same as the Federal <br />Regulations at 40 CFR Par[ 112, and therefore, under §1 i2.7(j) the site is in conformance with <br />applicable requirements. <br />• <br />9 <br />
