NEPA Categorical Exclusion Determinations

Categorical exclusions are classes of departmental actions that the Department of Energy has, by regulation, determined do not individually or cumulatively have a significant effect on the environment and for which, therefore, neither an environmental impact statement nor an environmental assessment is required. In accordance with DOE’s policy to further transparency and openness in DOE’s implementation of NEPA, Southwestern will, effective November 2, 2009, post classes of departmental actions which Southwestern’s NEPA Compliance Officer has determined are classified as categorical exclusions pursuant to the parameters set forth in Appendix B of DOE’s NEPA regulations (10 C.F.R. Part 1021).
