28 October 2020 AdvancedGeo <br /> Project No. 20-6092 An Employee-Owned Company <br /> Page 7 of 20 <br /> As described in Section 4.4 of this Plan, the operational and emergency capacity of the <br /> containment areas are sufficient to handle the quantity of oil expected to be discharged <br /> in the petroleum storage areas due to accidental damage or rupture to any of the <br /> containers with petroleum. Any leakage from a container would be detected visually <br /> during daily scheduled visual inspections by Facility personnel. <br /> The new and used oil /filter storage drums are elevated on spill pallets and have all sides <br /> visible or on mobile containment systems. Any leak would be readily detected by Facility <br /> personnel before discharging to navigable waters or adjoining shorelines. Corrosion <br /> poses minimal risk of failure since drums are single-use and remain on site for a relatively <br /> short period of time (less than one year). The petroleum storage area is inspected daily <br /> with a more intense inspection conducted monthly by the Facility Coordinator. This is in <br /> accordance with accepted industry practice for drum storage and provides an effective <br /> means of verifying container integrity, as noted by EPA in the preamble to the SPCC rule <br /> at 67 FR 47120. <br /> 4.2. SPILL REPORTING - 40 CFR 112.7(a)(4) <br /> The discharge notification form included in Appendix D is completed upon immediate <br /> detection of a discharge and prior to reporting a spill to the proper notification contacts <br /> after evaluation by Facility Management and as applicable to limits described in <br /> Section 2.0. <br /> 4.3. POTENTIAL DISCHARGE VOLUMES AND DIRECTION OF FLOW - 40 CFR <br /> 112.7(b) <br /> Table 5 presents expected volume, discharge rate, general direction of flow in the event <br /> of equipment failure and means of secondary containment for different parts of the Facility <br /> where oil and/or petroleum fuel is stored, used or handled. <br /> 4.4. CONTAINMENT AND DIVERSIONARY STRUCTURES - 40 CFR 112.7(c) <br /> Methods of secondary containment at the Facility includes double-wall ASTs for the two <br /> 6,000 gallon diesel AST's that are manifolded together, the two 1,000 gallon new and <br /> used oil, and the 120 gallon new motor oil tank. Secondary containments and spill pallets <br /> for the 55 gallon drums that store petroleum products are provided. Additionally, land- <br /> based spill response kits (e.g., booms or absorbents) are present to prevent petroleum <br /> oil and/or lubricants from reaching navigable waters or adjoining shorelines. <br /> 4.4.1. Spill Pallets <br /> Each secondary container or spill pallet has a minimum 110% capacity of the petroleum <br /> container placed on it, which can effectively contain the volume of any single 55-gallon <br />
