Bureau of Land Management Environmental Assessment Royal Gorge Field Office DOI-BLM-CO-F020-2019-0056 EA Processing operations would consist of a crusher/screener plant with a stacker on a 11/2 inch rock conveyor to process and stockpile material further from the highwall. The commodities would be roadbase,3/4"minus and 11/2"minus, all in various colors depending upon demand. Production would be approximately 50 short tons per hour from the crusher/screener plant with approximately 40,000 short tons of material produced per year; however,this is subject to change based on the demand and viability of the products. Below Table 1 lists the types of equipment and their subsequent use(s) onsite: Table 2.1.1:Description of equipment types and uses during proposed mining and processing activities Equipment Type Use Power Screen Marc3 Processing Koleman Stacker Processing KPI 4233 Impact Crusher Processing Portable Metso Screen Processing Plant with Processing conveyor system CAT 938 Loader Mining/Processing CAT D9 Dozer Mining Komatsu PC 300 Excavator Mining A BLM right-of-way(ROW) is authorized with Sangre de Cristo Electric Association(SDCEA) and requires a 20-foot buffer from the powerline center. The operator has no intention of disturbing the powerline or the power poles; however, the operator will acquire an agreement with Sangre de Cristo Electric prior to the issuance of the mineral material contract. The only water usage would be for fugitive dust control which would be managed using a water truck to control dust on the access road,processing area,product stockpiles and all other disturbed areas. The water truck will be kept onsite with potentially needing to travel on the highway for refill once or twice a week during drier weather and higher production and haul demand. Dust control requirements will be outlined in the Colorado Department of Public, Health and Environment (CDPHE),Air Pollution Emissions Notice(APEN)permit. BLM will require a copy of this permit prior to the issuance of the mineral material contract(reference permit section below). The northwest corner mine boundary intersects with a 107-power withdrawal which initially withdrew the area to mineral entry; however, a memorandum issued on July 20, 1966 between the Department of Interior and the Federal Energy Regulatory Commission(FERC), formerly the Federal Power Commission, gave BLM the FERC's consent to dispose of mineral materials from powersite lands (h3600-1; Chapter X, Special Stipulations,part G, Powersite Withdrawals). The memorandum requires that: 9
