All licensing and regulatory actions subject to this subpart require an environmental assessment except those identified in §51.20(b) as requiring an environmental impact statement, those identified in §51.22(c) as categorical exclusions, and those identified in §51.22(d) as other actions not requiring environmental review. As provided in §51.22(b), the Commission may, in special circumstances, prepare an environmental assessment on an action covered by a categorical exclusion.
