Denver firm to revive quarry near Glenwood

A Denver-based company plans to revive operations at a quarry near Glenwood Springs to produce rock dust for use in coal mining operations.

CalX Minerals bought the mining claims and mining permit for the Mid-Continent Quarry along Transfer Trail just outside Glenwood Springs, the Bureau of Land Management said in a news release Tuesday.

The quarry has been inactive for the past several years but has been in operation on and off since the 1950s.

Mid-Continent once operated a coal mine near Redstone. Rock dust is used to reduce the danger of explosions in coal mines.

CalX has notified the BLM it plans to begin conducting quarry work later this month or in July.

“Mining operations have been authorized by BLM and the state of Colorado on this claim for several decades,” BLM Glenwood Springs Field Manager Steve Bennett said in a news release. “Since operations will continue to be confined to the permitted area, no new permits or authorizations are required from BLM for operations to begin.”

Quarried rock will be ground on site. Grinding will occur indoors and around the clock.

Mining, crushing and screening will be limited to 7 a.m. to 5 p.m. Monday through Friday.

Mill facilities will be designed to contain much of the noise and dust produced during grinding. Two to four grinders are planned, and one to four adjacent silos. Facilities will be placed behind a ridgeline and painted a BLM-approved color to reduce visual impacts.

About one blast a month will occur between April and December each year. The company doesn’t expect the blasting to generate much noise or vibrations, but it will be monitored closely to ensure vibration control, the BLM said.

The work is expected to result in truck traffic of about 20 round trips per day. CalX will do dust control and road maintenance, mark the road with signs, and work to ensure winter recreationists continue to have safe winter access on the road, which leads to the Flat Tops, the BLM said.
