Activity-Specific Categorical Exclusion for Deep Borehole Drilling, Sampling, and Characterization for the Proposed Natural Gas Pipeline from Pasco, Washington to the Hanford Site 200 East Area
CX(s) Applied: B3.1
Offices(s): River Protection-Richland Operations Office
The Department of Energy, Richland Operations Office is preparing an Engineering Feasibility Study (EFS) and Environmental Impact Statement to analyze alternatives for acquiring a pipeline and utility services to provide natural gas to support facilities in the Hanford Site 200 East Area. The EIS (DOE/EIS-0467) will analyze potential environmental impacts of constructing, operating, and maintaining roughly 30 miles of buried pipeline and ancillary equipment from an existing natural gas pipeline in Pasco, Washington. This Categorical Exclusion covers up to five deep vertical geotechnical soil borings proposed to collect data on geologic unit depths, thicknesses, and material properties to support pipeline design and construction under the Columbia River.
