January i 0, 2008 Tony Petersen, Community Development Director Gilpin County Planning Commission P. O. Box 203 Eureka Street Centiral City, CO 80427 1tE: Proposed MMRR Aggregate Quarry / Gilpin County /Pending Application M2004067 Dear Mr. Peterson, The Upper Clear Creek Watershed Association (UCCWA) is the designated 208-management agency responsible for testing, monitoring, overseeing, and reporting water quality and water resources issues through the upper portion of the Clear Creek Watershed. Our membership includes 20 municipalities, counties, and dischargers located in the upper Clear Creek watershed in Clear Creek and Gilpin Counties. As such, we have a responsibility to review the potential impacts to water quality from the proposed MMItR mining operation. At our meeting on January 10, 2008, after hearing a presertation on the MMRR Quarry application from Alex Schazt of Banks and Gesso, LLC, the membership of UCCWA voted 8 to 0 with 2 abstentions to submit this letter of opposition to the MMRR Quarry proposal, Members have reviewed relevant parts of the 629 page application and our opposition and concerns are as follows: I. Dust Control - We are concerned that the dust control plan as described in the proposal will be insufficient to prevent dust, sift, and sediment from leaving the quarry and eventually being transported into the North Fork Clear Creek. 2. Dust Control - A vacuum sweeping truck should be employed to control and coIiect dust, silt, and sedimer to preclude transport from the quarry site. 3. Dust Coutro! -Afire cleanup station should be required along with alI necessary procedures for cleanup of truck tires prior to truck entry onto Highway l 19. Any materials transported onto to the Highway are likely to eventually make their way irrto the North Fork Clear Creek. 4. Water ControUDiversion structure, construction, operation and maintenance -While the Best Managemem Practices (BMPs) describe in Appendix E sound good, we are concerned that if there are no requirements for maintenance of these BMPs, then their effectiveness will be quickly compromised. We are concerned that sediment and silt may still reach North Fork Clear Creek. MMRR should submft their Stormwater Management Plan for our review and for the review of Gilpin County. The Stormwater Management Plan should include information about inspections
