Request for Information and Associated Comments
- Request for Information (87 FR 68385; November 15, 2022) to help inform potential updates to categorical exclusions in DOE’s regulations implementing NEPA. DOE explained that it “is considering revisions to ensure that its NEPA reviews are aligned with the latest DOE programs and initiatives for clean energy and electricity transmission projects, fully consider potential environmental impacts and community concerns, and are efficient and effective at informing DOE decisions.” (NOTE: Relevant to this proposed rulemaking, commenters asked DOE to add energy storage systems to its categorical exclusions, to expand the scope of its categorical exclusion for upgrading and rebuilding powerlines, and to expand its categorical exclusion for solar photovoltaic systems to at least 200 acres within previously disturbed or developed areas. DOE addresses these and related comments in its discussion of proposed changes in section II.B of its Notice of Proposed Rulemaking.)
- Re-opening of Public Comment Period for Request for Information Regarding Categorical Exclusions (88 FR 2029; January 11, 2023). DOE re-opened the comment period for 30 days to allow interested parties additional time to provide input.
