According to Grand County Water Quality Manager Katherine Morris, polluted discharge from the Moffat Tunnel has adversely impacted the Fraser River. The Grand County water quality team recently wrote two letters to the Colorado Department of Public Health & Environment, outlining its concerns with violations by Union Pacific Railroad, which manages the tunnel. During a Grand County Board of Commissioners meeting March 11, 2025 Morris explained that polluted water from the tunnel enters the nearby Fraser River, which is a main tributary of the Colorado River. This ongoing problem began after the tunnel was completed, and Grand County government began advocating to fix the problem nearly two decades ago…
In the early 2000s, residents and governmental officials raised alarm about pollutants and increased turbidity (or clarity issues) in the Fraser River when water was discharged from the tunnel. The tunnel bores through James Peak. Groundwater from cracks in the mountain rock seeps into the tunnel, and that water needs a way out. Coal dust, heavy metals and other particulate matter can travel into the Fraser River through the runoff. At the time, a water treatment plant existed on the east portal of the tunnel but not on the west portal at Winter Park. People questioned why there was no treatment plant to protect Grand County, home to the headwaters of the Colorado River. Over the years, Union Pacific received fines and a cease-and-desist order. The railroad finally built a treatment plant in 2017, but issues have continued — even worsened in some cases, Morris said. A water centrifuge at the plant is designed to separate solids from the water, creating a sludge-like “centrifuge cake” that is put in a drum and disposed of in Utah. (This disposal has raised its own concerns.) The remaining water is discharged into the river.
