CESPK-CO-R <br />Notice Number 199675341 <br />Approximately 5 acres per year will be witted in six phases so that no more than 40 acres <br />will be disturbed at any one time. The maximum production of the operation will 450,000 <br />tons per year, which is the same as the existing operation. Aggregate processing, the <br />asphalt and concrete plants, office and associated facilities will be located on an operations <br />pad. Specific project features include: a 1,200-squaze foot office building; an 8,000-square <br />foot maintenance building; a concrete batch plant; an asphalt plant; a crusher; a wash plant; <br />storage azea for screens, motors, rollers, etc.; fuel storage azea; a scale; and a conveyor <br />system. <br />The conveyor system will be used to transport aggregate from the active pit to the <br />processing plant. The conveyor will be approximately 4,800 feet in length and is proposed <br />along the west side of the permit boundary. The conveyor will reduce the amount of trucks <br />and equipment needed to transport aggregate on site. The operation will include haul <br />trucks, fuel trucks, front end loaders, scrapers, concrete and asphalt trucks, and related <br />equipment. <br />Access is proposed at a new location from the entrance to the existing operation. According <br />to the applicant, this will allow for the use of the existing acceleration deceleration lanes on <br />State Highway 9. <br />ALTERNATIVES: Prior to the purchase of the Maryland Creek Ranch, the applicant <br />assessed alternatives. The applicant considered the following criteria for aggregate <br />operations feasibility: (1) Aggregate Quantity: A reserve of at least 25 to 30 years is <br />needed to justify the capital expenditure; (2) Aggregate Quality: The deposit must meet <br />certain criteria in terms of percent fines, particle-size distribution, soundness, and hardness; <br />(3) Deposit Configuration and Location: The deposit must have an adequate configuration <br />(e.g., not long and narrow and have suitable access to allow for mining; (4) Land Size: <br />Adequate land for processing facilities,-and asphalt-and concrete plants must-be available in <br />close proximity to the deposit. A minimum of 25 acres is required; (5) Accessibility: The <br />deposit must be located in close proximity to the mazket area to avoid high haulage costs <br />which would make it uncompetitive, and close to the processing areas for the same reason; <br />(6) Water Rights: Water rights must be available to replace depletions from water used for <br />dust control, aggregate loss, and evaporation from settling and aggregate ponds; and (7) <br />Availability: The land containing the deposit must be available for sale or lease. <br />In addition to the "no action" alternative, the applicant provided information on the <br />following alternatives: <br />* Expansion of the existing operation on the East side of Highway 9 <br />* Hardrock mine <br />* Other potential alluvial deposits in Summit County, and <br />* Moving the operation across the highway on the Maryland Creek Ranch. <br />,,: ~, <br />The applicant discussed each alteroative in terms of the criteria stated above and their <br />wetlands impacts, logistics, costs, and technology. This information is too voluminous to <br />include in this notice. This information may be reviewed at our office in Grand Junction, <br />Colorado (address below). <br />The applicant also identified efforts to minimize and avoid on-site impacts to wetlands. <br />These included reducing the size of the operations pad azea to 25 acres, eliminating <br />crossings of Maryland Creek and other drainages for access and haul roads, including a 100- <br />foot buffer zone (50 feet on each side) adjacent to Maryland Creek, and avoiding the <br />• <br />
