CX-003344: Categorical Exclusion Determination

Energy Systems Integration Facility Subsurface Exploration Program for Geothermal Potential; National Renewable Energy Laboratory Tracking Number 10-037
CX(s) Applied: A9, B3.1, B3.6
Date: 08/13/2010
Location(s): Golden, Colorado
Office(s): Energy Efficiency and Renewable Energy, Golden Field Office

The proposed project would be for a geothermal test boring associated with the Energy Systems Integration Facility (ESIF) construction activity located at the National Renewable Energy Laboratory's (NREL) South Table Mountain (STM) Complex, City of Golden, County of Jefferson, and State of Colorado. The Department of Energy funding would be used to drill one 5 1/2 inch bore hole to collect samples of underlying bedrock for analysis. The samples would be analyzed to investigate the feasibility of establishing a geothermal heating, ventilating, and air conditioning system (HVAC) for the ESIF building. A geothermal HVAC system would further NREL's goals of utilizing renewable energy sources on the STM site to demonstrate its technologies and to become a more sustainable institution.
