Glenwood Hot Springs Protection Act Blocks Limestone Quarry Expansion in Garfield County

The Glenwood Hot Springs Protection Act is a targeted piece of legislation designed to stop the expansion of industrial mining on specific federal lands in Colorado. By order of this bill, the Secretary of the Interior is prohibited from processing or approving any applications that would grow the footprint of the Mid-Continent Limestone Quarry. This isn't a general suggestion; it’s a hard stop on new mining claims, mill site claims, and mineral material sales contracts across several specific sections of land in Garfield County, including parts of Township 5 and 6 South. If you’ve ever visited the area, you know the stakes: the bill specifically protects the Bureau of Land Management (BLM) land that surrounds the iconic Glenwood Hot Springs.

Drawing a Line in the Limestone

This bill creates a legal barrier around five specific sections of land—Section 4, 25, 30, 31, and 36—to ensure that the current quarry operations cannot creep further into the landscape. For a local business owner in Glenwood Springs or a resident who relies on the area’s tourism-driven economy, this provides a layer of long-term certainty. By freezing the quarry’s footprint, the legislation aims to protect the complex underground hydrology that feeds the hot springs. Because the bill is so specific about the geographic coordinates, there’s very little room for bureaucratic 'interpretation' regarding where mining can and cannot happen.

Local Impact and Industrial Limits

While this is a win for environmental preservation and the local tourism sector, it draws a definitive line for the mining industry. Any company or individual looking to scale up limestone extraction in these specific zones will find their expansion plans legally blocked. For the workers at the existing quarry, the bill doesn't shut down current operations, but it does cap the future growth of the site. It’s a classic trade-off: the bill prioritizes the long-term health of the natural hot springs and the scenic value of the Colorado River valley over the industrial expansion of mineral resources in this particular corner of the state.
