The facility drainage systems are adequately engineered to prevent oil from leaving the facility during dry weather conditions. In the event of an equipment failure during dry weather conditions, discharged oil that entered the wet well system will terminate at the storm water pump station. The pumps are set with an automatic turn on system if water level reaches a certain level.They are also equipped with a manual override shut-off. If a release of oil substances occurred, NCYCC personnel can shut down the pump stations until the oil is cleaned up. 6. Petroleum Storage Tanks The following section provides a description of the oil storage containers located at NCYCC. Tables 1 and 2 provide a summary of the stationary and portable bulk oil storage containers, respectively, at NCYCC including location, type of tank, content, and volume. Additional information, including detailed description of each tank (location, capacity, type, etc.) are provided in Appendix C, Table C-1 and Table C-2 and discussed in Section 6. Potential spill scenarios for each tank and activity, such as fuel transfer, are provided in Appendix C, Table C-3. The approximate potential direction of surface run-off is shown on Figure 5. A petroleum spill contingency plan is included in Section 8 of this SPCC Plan. The contingency plan addresses immediate actions, notification procedures, and containment and removal procedures following discovery of a petroleum discharge. The spill contingency plan also identifies the authorities, responsibilities, and duties of personnel who are involved in petroleum removal operations. 6.1 Stationary Storage Tanks Table 1 provides a summary of the stationary, bulk oil storage containers at NCYCC including location, type of tank, content and volume, secondary containment, and other criteria that affects release potential and spill prevention. 6.2 Portable Storage Containers Portable containers of oil-based materials, including 55-gallon drums, are kept at the Auto Shop at the NCYCC facility. Although the containers are portable, they typically remain located in their respective storage areas and generally are not transported around the facility. Table 2 lists the portable storage containers at NCYCC including location, type of container and volume, contents, secondary containment, and other criteria that affects release potential and spill prevention. 6.3 Material Compatibility Each AST and oil storage container is of UL-142 construction and is compatible with the oil substances they contain and conditions of storage. All ASTs and portable tanks and drums are made of steel which is compatible with the stored materials. 6.4 Secondary Containment The secondary containment method for each oil storage container is listed in Tables 1 and 2. All ASTs indicated as double-wall are constructed with an integrated containment system. Portable tank indicated as single-wall has secondary containment when stored. All 55-gallon drums are either placed Page 113
