i SUMMARY OF THE PROJECT <br />I- • <br />ARCO Coal Company (ARCO), a Division of Atlantic Richfield Company, intends to build <br />and operate a .250M ton per year coal mine on its Mt. Gunnison property near Somerset, <br />Colorado. This summary is provided so that the Contractor may have a general under- <br />standing of the overall project. <br />The mine will have drift access, with the raw coal passing from portal to breaker to an <br />off-track silo to a loadout via a conveyor belt system. The surface facilities and mine <br />portal for the initial .250M ton per year mine will actually be designed and constructed as <br />a 1.4M ton per year mine with the exception of silo capacity. Ultimately the mine will be <br />expanded to a production of 2.8M ton per year. <br />Development schedules allow approximately 12 months for construction of the mine <br />facilities upon receipt of all regulatory agency permits. First coal production will occur <br />five months after start of construction; however, this will not interfere with the <br />construction efforts. After the access road is built on site, constriction of the mine <br />portal, coal handling and support facilities may begin. A drainage system complete with <br />ditches, pipes and sedimentation ponds will be built in compliance with the Federal Office <br />of Surface Mining Regulations. The initial office and changehouse structures will be <br />j temporary trailers until the mine begins to expand to 1.4M tons per year. At that time, <br />additional belts, silos, ponds and permanent buildings will be built. A small, permanent <br />and expandable shop/warehouse will be installed as part of the .250M ton per year mine. • <br />An 5,000 ton silo, separate from a preweighed loadout system built on a 30-car siding, will <br />be used. Topsoil and waste rock will be removed and stored in separate areas according to <br />the Office of Surface Mining regulations. Room must be left near the breaker for a <br />possible future coal preparation plant. Room must be provided for temporary mine rock <br />and emergency coal stockpiles. <br />Security will be provided by such measures as fencing end a guardhouse: Afire protection <br />system, complete with a water tank, pipelines, hoses, sprays and extinguishers will be <br />provided for all buildings and structures. Mine supplies will be stored in the warehouse <br />and supply yard. Fresh water will be pumped from the river and stored in a pond. This <br />' water will then be treated as required and pumped directly into the mine, with potable <br />~- water being stored in a tank. Sewage will-be processed in a package treament plant. <br />Drainage water will be collected and processed in runoff water ponds. Power will be <br />~ supplied via a tap line from the Delta-Montrose Electric Association's existing 44kV <br />~ transmission line which crosses the plant site. Voltage will be stepped down at a sub- <br />station. <br />•All final decisions on every aspect of design and construction for this project will be made <br />` by ARCO. Every effort should be made to minimize capital expenditures in this project. <br />Table A is a summary of all the proposed facilities for the initial .250M ton per year mine. <br />`_ <br />
