Help Glenwood Springs prevent future mining at the Transfer Trail limestone quarry

The Glenwood Springs area community and those who visit our community  stand together to oppose future mining at the Transfer Trail limestone quarry.

Right now, there are two things happening at once.

Don't Mine Glenwood Springs

Congressional action

U.S. Rep. Jeff Hurd, a Republican representing western Colorado, and U.S. Sen. Michael Bennet, a Democrat, have introduced the bi-partisan Glenwood Hot Springs Protection Act. It would prevent the Dept. of Interior from approving the mine expansion proposal.

An image of the first page of HR 9826U.S. Sen. John Hickenlooper, also a Democrat, is co-sponsoring Sen. Bennet’s legislation. “He’s about as pissed off as I am about this,” Hickenlooper said of Bennet during a July 3 visit to Glenwood Springs.

U.S. Bureau of Land Management review of new mining permit application

While an official decision issued by the U.S. Department of Interior in 2025 forced Rocky Mountain Industrials (RMI) to stop mining operations, the company is now seeking approval from the U.S. Bureau of Land Management for a new mining permit. It asks for:

  • Expansion of the mine from the current size of 16 acres to 56 acres, extending hundreds of feet upslope.
  • A mineral materials sales contract to sell limestone aggregate from the expanded mine.
  • Approval of measures to resolve longstanding mining permit violations.

BLM staff in the Colorado River Valley Field Office are conducting a technical review to identify impacts of the proposal to other resources. After the technical review is complete, BLM has stated it will launch a public review process of the permit application.

Issues simmering in the background

Increased reclamation bond for quarry site

Increased reclamation bond for quarry site

The Colorado Division of Reclamation, Mining & Safety (DRMS) is the lead agency to oversee reclamation of the site. In March 2026, DRMS increased the reclamation bond to $1.2 million, to be paid in full by March 2027.

RMI’s future plans for a massive limestone mine

RMI’s future plans for a massive limestone mine

Rocky Mountain Industrials still holds 44 unpatented mining claims under the existing quarry and running up the mountainside. It may attempt to revive its 2019 proposal to further expand the quarry.

Permanent protection to prevent more mining

Permanent protection to prevent more mining

The mine expansion poses unacceptable threats to the Glenwood Springs community. Because we value the environment and our quality of life, our aim is to stop the mine expansion for good.

The quarry is on federal public lands

The quarry site and RMI’s mining claims are on public lands managed by the U.S. Bureau of Land Management (BLM).

These are OUR public lands. We have a say in what happens!

 

The Glenwood Springs community is united in opposition.
