Giant Cement Company - Executive Summary |
|
Giant Cement operates a portland cement manufacturing operation on an approximate 1385 acre parcel of land, located in Harleyville, SC. The facility operates 4 rotary kilns and associated raw and finished material processing operations in the production of portland cement. Raw material is mined on site and processed in preparation for use in the production of portland cement. The Giant Cement facility also includes a fully permitted waste fuel storage tank facility. Waste fuel is received at the Giant Cement faciity via tanker truck from off site and pumped into one of several waste fuel blending tanks. The waste fuel is blended to meet burning specifications for use as fuel in the adjacent cement kilns. The tank farm facility consists of 6 storage tanks and associated ancillary equpment. Waste fuel is transferred to the cement kilns via aboveground pipeline. The Giant Cement storage tanks are interconnected via pipelines and are also considered co-located within the tank farm and therefore, for purposes of compliance with 40 CFR Part 68, the Giant Cement facility is considered to have one regulated process, the tank farm storage facility. The threshold quantity determination performed at the Giant Cement facility used several conservative assumptions as outlined in the EPA RMP guidance document for warehousing (1/99). From this threshold determination, the facility developed a list of regulated substances that could potentially (although unlikely) be present in the regulated process above the applicable threshold quantity. An off-site consequence analysis was then performed in accordance with EPA guidance to determine the distances to the endpoints for each substance. From this analysis, it was determined that the facility is subject to the RMP Program 2 requirements. The attached RMP details the Giant Cement Program 2 Prevention Program. |
