This letter is provided by the Douglas Mountain Residents Association (DMRA) in response to the
MMRR Quarry application, with a proposed location approximately 7,000 feet northwest of the junction
of Highway 119 and Douglas Mountain Drive. The project proponent and applicant is Clear Creek
District Water Providers I.I;C; 5560 Quebec Street, Suite 110, Greenwood Village, Colorado.
Douglas Mountain Filing No. 1, a residential area, is located immediately east of the proposed mining
facility. We are adamantly opposed to the construction and operation of this or any other mining facility
of this type in this area. We have had direct experience with the impacts associated with the operation of
the Albert Frei & Sons Quarry on US 6 in Clear Creek Canyon. None of the regulations associated with
the operation of this facility have been enforced by the State of Colorado, setting a very poor example of
rock mining in this sensitive region. As such, we request that DMG delay a decision to issue a mining
permit until the following issues, at a minimum, are fully considered and addressed.
With respect to the quany application we have the following specific comments:
Page 10 Blasting Procedures
Both private and public stnrctures must be protected from the impacts of blasting and,rock movement.
The most stringent OSM, US Bureau of Mines, or other relevant ground vibration standards must be
adhered to. A plan must be developed that includes monitoring and reporting to ensure the protection of
all structures within the DMRA area. Compliance with these standards must be documented through a
detailed monitoring system to be installed on Douglas Mountain Drive and in DMRA areas above the
quarry, following review and approval by DMRA. Monitoring results will be provided to DMRA, with
interpretation, on a monthly basis. The impacts of blasting and blasting residuals on ground water flow,
well yields, and water quality must be documented and fully mitigated.
Page 17 Eahibit G Water Information
Provide DMRA with the site drainage design and runoff control plans. Where will the industrial water
supply (proposed to be trucked to the facility) be obtained? How does the proposed volume, 30,000
gallons per day, compare to the volume of water used for similar purposes at the Frei Quarr}f? Where will
the crusher fines be stored and what is the potential for this material to release heavy metals in dissolved
or particulaze form? What are the potential metal, nutrient, and sediment concentrations in runoff water
and how will this impact North Fork Clear Creek?
Page 19 Eahibit H Wildlife Information
A site-specific wildlife inventory was not performed. The wildlife and vegetation information used for
the application was from a different area that is not relevant to the proposed facility. A detailed site-
specific inventory of wildlife and vegetation is required for the facility as part of the application. The
Colorado Division of Wildlife should also be consulted on this matter. The Reclamation Plan, including
vegetation species and cover requirements must be provided to DMRA for review,
