The South Dakota Wheat Growers Association Willow Lake, SD facility stores and handles a variety of products and commodities associated with the production of crops. Anhydrous ammonia and liqified propane gas is a product regulated by Part 68 of the CAA and are in use at this facility at regulated quantities. Anhydrous ammonia, for retail sales, is stored in two above ground storage tanks (AST) on concrete cradles. Incoming prduct arrives by semi-bulk trucks. The facility also has 13 nurse trailers that allow farmers to supply nitrogen to the field. Liqified propane gas, for crop drying, is stored in one above ground storage tank (AST) on concrete cradles. Incoming product arrives by semi-bulk trucks or smaller bobtails. (c) The worst-case release scenario(s) and the alternative release scenario(s), including a dministrative controls and mitigation measures to limit the distances for each reported scenario. In our emergency planning we have considered two scenarios for each chemical, these involve a worst case release scenario and a more likely but still uncommon alternate scenario. The worst case scenarios involve the release of the entire contents of the largest tank of anhydrous ammonia or liquid propane tank. The alternative scenario for anhydrous ammonia involves a nurse tank hose rupturing. The alternative scenario for liquid propane gas involves a transfer hose rupturing. This planning was aided by RMPComp, a program designed by the EPA that provides conservative results. The population within a radius supplied by each scenario could be effected in the remote chance of a release occuring.
