BLM Begins Public Scoping For Mineral Materials Sale Proposal

CAÑON CITY, Colo. – Today, the Bureau of Land Management (BLM) Royal Gorge Field Office announced the beginning of a 30-day public scoping period for a proposed expansion of the Parkdale Quarry west of Cañon City. 

BLM has received an application from Martin Marietta Materials, Inc. for a renewable 10-year competitive contract for the sale of mineral materials. The proposal would permit Martin Marietta to expand its operation north and west onto approximately 700 acres of BLM lands. The expansion would provide access to 400 million net tons of aggregate. Parkdale Quarry currently operates on private land. 

The aggregate would be used in the production of asphalt and concrete, as well as for railroad ballast. Access to the BLM reserves would help sustain supplies of aggregate to meet future demands in southern Colorado, as well as into the Denver area and Kansas. 

“Mineral materials from BLM lands are critical to meet demands as Colorado continues to grow,” said Royal Gorge Field Manager Keith Berger. “We look forward to hearing the public’s input on the proposal.”

In Fiscal Year 2018, non-energy minerals on BLM lands in Colorado generated approximately $194 million in economic output and supported 650 jobs.

The public scoping process will help BLM determine relevant issues that will influence the scope of the environmental analysis and guide the process for developing the Environmental Impact Statement. The BLM will host an open house public meeting August 15 in Cañon City from 4:30 to 6:30 p.m. at The Abbey Events Complex, 2951 East Highway 50.

Public comments will be most helpful if received by August 30, 2019 and must be submitted through the BLM ePlanning site at or mailed to “Parkdale Quarry Expansion Comments,” 3028 E Main Street, Cañon City, CO 81212.
