This report presents a part of the first-year findings from a 2.5-year study of the environmental impacts of energy-resource development in the Denver and Cheyenne Basins, Colorado. The Denver and Cheyenne Basins lie within the plains of eastern Colorado, adjacent to the Front Range and Laramie Range. All or part of Adams, Arapahoe, Boulder, Denver, Douglas, Elbert, El Paso, Jefferson, Larimer, Morgan, and Weld Counties are within the two basins.
The primary goal of this investigation is to develop a thorough understanding of the various environmental impacts that may result from energy-resource areas development in the study area. A secondary goal is to identify areas underlain by available energy-resource deposits, both fossil fuel and uranium, that need to be protected from alternate land uses that may prohibit or inhibit future resource development, as defined by Colorado House Bill 1529 (1973).
The first year of this study concentrated only on coal and lignite resources. This report along with two open-file reports by the CGS (OF-78-08 and OF-78-09) represent the results of this phase of the investigation.
