Power plants and mining operations dominate a new government list of polluted sites around Colorado.
Every year, the Environmental Protection Agency requires companies to report releases of waste or materials containing any of the 582 chemicals it considers toxic.
A Rocky Mountain News analysis of 2003 EPA data says the top waste generator in Colorado last year was the Cripple Creek and Victor Gold Mining Company southwest of Colorado Springs.
It released more than three million pounds of waste at its gold mine near Victor.
At Fort Morgan, an Excel meatpacking plant, a sugar processing operation and a food processing factory spewed 2.5 million pounds of toxic substances into the ground, air and water. It was second on the EPA's list.
