Bureau of Land Management Finding of No Significant Impact <br /> Royal Gorge Field Office DOI-BLM-CO-F020-2020-0036 EA <br /> may occur on BLM managed lands until the NEPA and contract issuance process have been <br /> completed. <br /> The application for a mineral material sale's contract would account for future federal mineral <br /> production and all reclamation requirements associated with any past,present,and future <br /> disturbances.Per the 1987 CDRMS permit,production was projected to be between 5,000 and <br /> 10,000 tons per year; however, with the additional reserves the production rate is anticipated to <br /> increase to 8,000 tons per month for a maximum total production of 96,000 tons per year. Active <br /> mining is seasonal;however,production would be year-round with product material stockpiled <br /> for use during winter months. Seasonal operations would be from November to April for 40 <br /> hours per week and May through October for 50 hours per week. <br /> Intensity: <br /> I have considered the potential intensity/severity of the impacts anticipated from the Competitive <br /> Mineral Materials Sale at the Black Obsidian Quarry relative to the 10.75 acres suggested for <br /> consideration by Colorado Quarries Inc.With regard to each: <br /> Impacts that may be beneficial and adverse: <br /> Through the environmental analysis,it has become apparent that adverse impacts to the human and <br /> natural environment can be managed by applying project design features(PDFs)and best <br /> management practices(BMPs).No issues were determined by the BLM RGFO resource specialists <br /> during the EA analysis process. <br /> Below is a summary of the Operator proposed PDFs/BMPs: <br /> 16.Agreement between the mining claimants and Colorado Quarries Inc. regarding mineral <br /> rights under the Mining Law. <br /> 17.Access agreements between private landowners and Colorado Quarries Inc. <br /> 18. All stormwater controls installed prior to initiating expansion. <br /> 19.All fuels and other chemicals would be stored in secondary containment and spill <br /> contingency plan and kit available for spill/leak cleanup. <br /> 20. Perimeter fence and locked gate would include all expansion disturbance to decrease <br /> safety concerns to the general public. <br /> 21. Site specific trainings to employees and visitors(e.g., inspectors,haulers, etc.). <br /> 22. Compliance with all other federal, state and county laws and regulations. <br /> 23. Licensed blaster onsite during all scheduled blasting. <br /> 24. Topsoil and overburden stockpiles would be sloped and revegetated for stability. <br /> 25. Removal of non-operable equipment during seasonal shutdowns or non-operational <br /> periods. <br /> 26.Routine site monitoring during non-operational periods. <br /> 27. Blasting materials stored in an ATF authorized storage locker. <br /> 2 <br />
