Small quantities of petroleum products are stored in drums at the Maxim Crane Works facility. <br /> Secondary containment provided for drum storage areas has sufficient volume to contain the entire <br /> contents of the largest drum or ten percent of the total volume of drums, whichever is greater. The <br /> containment volumes are indicated in Section IV.B and Table 3. <br /> 3. Drainage of Rainwater from Containment Areas (40 CFR 112.8 (c)(3)) <br /> In the event of a major storm event that necessitates removal of storm water from a containment <br /> structure, the following procedures will be followed: <br /> • The accumulated liquid will be inspected for color, clarity, odor, or the presence of a <br /> sheen on the water surface. <br /> • If the accumulated liquid is confirmed to consist of rainwater only, valve on the <br /> containment are will be opened by authorized personnel and the storm water will be <br /> discharged to the adjacent drainage swale. <br /> • If the accumulated rainwater contains evidence of petroleum hydrocarbons, a sample of <br /> the water will be collected and analyzed to determine management options. The water <br /> will be pumped out of the containment area for off-site management. <br /> • A record of storm water inspections and discharges will be maintained using the form <br /> presented in Appendix E. The records will be maintained by the Shop Superintendent. <br /> 4.
