<br />Tssotaa <br />1.0 Project Description <br />L. C. Holdings, Inc. proposes to reactivate and operate an open pit mine (quarry) and <br />processinl; giant that will produce a superior quality, expanded shale, lightweight con- <br />struction aggregate. The project would be located approximately 11 miles north of <br />Golden, (:olorado in the Rocky Flats area of northern Jefferson County. The quarry <br />area is located adjacent to and west of Colorado State Highway 93, and the processing <br />plant arert is located adjacent to and east of Highway 93. The two areas of the project <br />are connected by an existing underpass beneath the highway. <br />Project d~:velopment would involve a rebuilding of a processing plant that currently <br />exists at the project site. The old processing plant was part of the Idealite mine and <br />processinl; plant which were operated from 1962 to 1975 by Great Western Aggregates, a <br />subsidiary of the Ideal Cement Company. After the project ceased operation in 1975, <br />the mining equipment and much of the processing equipment at the plant site were <br />removed and sold on the used equipment market. As a result, the processing area <br />presently consists of a mix of skeletal foundations and empty process buildings; whereas, <br />the product storage silos, the office building, and the maintenance shops remain largely <br />intact. <br />The shale quarry, located just west of the plant site, was abandoned after operations <br />ceased. iJo reclamation work was undertaken at the quarry. The proposed project <br />would produce 912 tons/day of lightweight aggregate product for up to 30 years. In <br />order to meet this annual product production rate, about 410,400 tons of raw shale will <br />be required to be mined annually from the quarry. It would employ approximately eight <br />administrative personnel and thirty operating personnel. <br />The raw material feed stock for the process plant is shale from the Pierre Shale Form- <br />ation. The material is soft and contains roughly 10 to 18 percent inherent moisture. <br />The existing quarry has disturbed approximately 29 acres. The shale to be used during <br />the first 11) years of the manufacturing process is currently exposed. The overburden <br />removed to obtain this shale was deposited on the north and west perimeters of the <br />quarry and revegetated. <br />-1- <br />Hydro-Search, II1C.
