The March 9, 1977 Golden Transcript reported that Coors was building a temporary bridge across Clear Creek. This was in preparation for delivery of a new coal-fired boiler.

In 1970, the plant had converted to natural gas, to improve their emissions. By 1977, in response to the "Energy Crisis" of that decade, they were reverting to coal. They were meeting emissions requirements by burning low-sulfur coal, using a coal gasification process, and installing improved air filters on their stacks.
