A 30-day public comment period for a proposed expansion of the Parkdale Quarry west of Cañon City began on July 31.
The evaluation process results from an application from Martin Marietta Materials Inc. to renew a 10-year contract on 700 acres of Bureau of Land Management land. An expansion would give access to 400 million net tons of aggregate, BLM said in a release. The aggregate is used to make asphalt and concrete to accommodate development in Colorado and Kansas.
Public comments will guide the Environmental Impact Statement. Send comments through the BLM site
