Garfield County Permit Enforcement

Garfield County enacts 1041 mining regulations

In 2020, while the RMI v. Garfield County lawsuit was moving through the court process, Garfield County worked to enact new mining regulations.

In May 2020, the County Commissioners voted unanimously to enact new standards for mining operations using Colorado’s 1041 review process.

The standards give Garfield County government clear and detailed authority to protect the environment and public health, safety and welfare from negative impacts of mining.

The standards are grouped in a single section of the Garfield County Land Use and Development Code, Article 14, replacing various pieces of regulation that were scattered throughout the code.

Under the standards, mining companies are given clear expectations for earning permit approvals and running mining operations over time.

Glenwood Springs Citizens’ Alliance strongly supported the county’s work in developing these new mining standards.

Rocky Mountain Industrials will have to follow the new standards if or when it applies for a county permit for its proposed mine expansion.

Garfield County regulatory action, 2019

In the fall of 2018, a few months after RMI announced its proposed mine expansion plan, the Glenwood Springs Citizens’ Alliance (GSCA) asked Garfield County to review operations at the  quarry. We suspected that several aspects of the mining operation did not comply with the special use permit that Garfield County issued for the quarry.

The county permit was first issued in 1982, when the coal mining company Mid-Continent Resources first opened the quarry. Garfield County amended the permit for the quarry in 2009, when CalX purchased the mining operation from Mid-Continent.

To verify our complaints, the Garfield County Commissioners directed county staff to review quarry operations and report back in 90 days. On March 25, 2019, the commissioners heard the staff report, along with public comments. On April 22, 2019, the commissioners held a formal public review meeting. More than 200 people attended.

Five areas of non-compliance

The three commissioners in office at the time — John Martin, Tom Jankovsky and Mike Samson — found five aspects of RMI’s current quarry operations to be out of compliance.

  1. The size of the quarry had grown to about 20 acres, exceeding the permitted size of 16.3 acres.
  2. RMI was mining and selling limestone for purposes not included in the county’s 1982 or 2009 permits. The limestone was only to be used for industrial purposes in coal mines and coal-fired power plants, but RMI was found to be selling it to other customers for road base and retaining walls.
  3. RMI continued to conduct rock-crushing operations during the winter closure period of Dec. 15 to April 15.
  4. RMI was not adhering to a maintenance plan for Transfer Trail, which had been in place since 2009. The plan was intended as a cooperative agreement with the Glenwood Caverns Adventure Park on shared use of Transfer Trail. Caverns owners contended that RMI had not reduced noise by enclosing its milling operation, didn’t use “discriminating” back-up beepers, and didn’t follow the plan for two-way radio communications on the narrow, winding road.
  5. RMI drilled several exploratory holes in the quarry area without obtaining necessary approvals.

On May 13, 2019, Garfield County issued a formal Notice of Violations, citing the five areas of non-compliance. The commissioners set a June 1, 2019, deadline for RMI to bring its operation into compliance.

RMI sues Garfield County rather than comply with permit

Rather than comply, RMI sued the county in May 2019. The suit alleged that Garfield County did not have environmental regulatory authority over mining operations on federal lands.

Garfield County ultimately prevailed in that legal battle. Visit this page for details.

Rocky Mountain Industrials continued to crush rock in its mill facility through the winter months until quarry operations were shut down in December 2024. Under its Garfield County permit, amended in 2009, the company was barred from crushing rock at the quarry from December 15 to April 15 in order to protect winter range for deer, elk, bighorn sheep and other wildlife.
