Bulk Storage Containers -40 CFR Part 112.8(c) <br />Compatibility -112.8 (c)(1) <br />as <br />Each oil storage container is constructed of steel or polyethylene and is compatible with the <br />oil it contains. In addition, the containers are compatible with the conditions of storage such <br />as pressure and temperature. Any proposed change in tank, pipe, containment, or oil product <br />shall be evaluated and certified by a registered Professional Engineer for compatibility prior <br />to implementing the change. <br />Secondary Containment -112.8 (c) (2) <br />See the secondary containment discussion in the following section for the oil storage areas <br />present at the facility: Containment and Diversionary Structures -40 CFR Part 112.7(c)(1). <br />Drainage of Accumulated Rainwater -112.8 (c)(3) <br />With the exception of the 1,000 -gallon diesel fuel and 180 -gallon fire water diesel fuel ASTs, <br />the bulk oil ASTs are located indoors. There is no accumulated rainwater associated with the <br />indoor ASTs. The facility drainage does not drain directly into a watercourse or into an <br />on-site wastewater treatment plant, therefore, the facility is not required to maintain <br />and complete a drainage release log per 40 CFR 112.8(c)(3)(ii), (iii), and (iv) each time <br />retained rainwater is discharged. <br />Rainwater may accumulate in the concrete berms associated with the 1,000 -gallon diesel fuel <br />and 180 -gallon fire water diesel fuel ASTs. The containment areas will be inspected monthly <br />and after each substantial rain event for the presence of accumulated water. The drainage of <br />accumulated rainwater from these containment areas is controlled by the following <br />guidelines: <br />Bypass Valve - 112.8 (c) (3) (i) <br />Accumulated rainwater is restrained in the containment area by a manually operated valve <br />located on the east side of the dike for the 1,000 -gallon diesel fuel AST, which is normally <br />kept in the closed position, unless draining water from the containment area. <br />Inspect Accumulated Rainwater - 112.8 (c)(3)(ii) <br />Prior to opening the bypass valve to drain the containment area of accumulated rainwater, the <br />surface of the water is inspected for the presence of an oil sheen or product floating on the <br />water. As stated earlier, the inspections are not required to be documented because the <br />facility drainage does not drain directly into a watercourse or into an on-site <br />wastewater treatment plant. <br />30 R 4 ti?U 17AHw-ust -20,16 <br />
