Snow lovers and the Durango City Council have called for tough action on climate change.
The councilors signed a letter delivered to the Environmental Protection Agency's office in Denver, supporting tough regulations for power plants.
"We support the ski area and are concerned about any environmental impacts that would damage Purgatory," Mayor Sweetie Marbury said.
The EPA's proposed new rules for coal-fired power plants would cut carbon pollution 30 percent nationwide by 2030.
The rule would allow states to choose how to cut the use of coal by expanding renewable energy and improving efficiency.
The letter campaign was started by Snowriders International.
Similar concerns were voiced by officials at the Colorado Association of Ski Towns meeting. Many look to beef up their summer offerings.
