_ t 8 * 0 FACILITY TANK TRUCK LOADING/ UNLOADING Ref: 40 CFR 112. 7(h ) This section lists the specific requirements in § 112 . 7 ( h ) - Facility tank car and tank truck loading/unloading rack . The Facility does not contain " loading/ unloading racks" as defined by the § 112 . 7 ( h ) . The Facility utilizes single hose connections and/or standpipes for the loading and unloading of oil supplies . These types of loading/unloading facilities are not considered " loading racks" under § 112 . 7 ( h ) . The following Facility responses identify additional measures, not required by the SPCC rule, which are implemented at the Facility . (1) Where loading/unloading area drainage does not flow into a catchment basin or treatment facility designed to handle discharges, use a quick drainage system for tank car or tank truck loading and unloading areas. You must design any containment system to hold at least the maximum capacity of any single compartment of a tank car or tank truck loaded or unloaded at the facility. Facility Response : The areas where the tanker trucks off- load are naturally graded so that the contents of a spill will remain within the Hot Plant area . The tank truck loading and unloading areas will be maintained so that ground surface flow remains within Hot Plant loading/unloading areas . (2) Provide an interlocked warning light or physical barrier system, warning signs, wheel chocks, or vehicle break interlock system in loading/unloading areas to prevent vehicles from departing before complete disconnection of flexible or fixed oil transfer lines. Facility Response : The drivers are required to use wheel chocks and use caution when conducting oil/fuel transfers . This is required to prevent the sudden roll of a vehicle that is still connected to the transfer hoses . In addition , all drivers must be authorized and abide by Facility rules and regulations to load and unload petroleum products . (3) Prior to filling and departure of any tank car or tank truck, closely inspect for discharges the lowermost drain and all outlets of such vehicles, and if necessary, ensure that they are tightened, adjusted, or replaced to prevent liquid discharge while in transit. (i) If a field-constructed aboveground container undergoes a repair, alteration, reconstruction, or a change in service that might affect the risk of a discharge or failure due to brittle fracture or other catastrophe, or has discharged oil or failed due to brittle fracture failure or other catastrophe, evaluate the container for risk of discharge or failure due to brittle fracture or other catastrophe, and as necessary, take appropriate action . Facility Response : This requirement does not apply; there are no field -constructed aboveground containers at the Facility . (3) (j) In addition to the minimal prevention standards listed under this section, include in your Plan a complete discussion of conformance with the applicable requirements and other effective discharge 24
