Environmental Impact Report Summary
Condense EIR (CEQA) or EIS (NEPA) technical findings into a legally actionable summary with record citations.
Authority status (read first)
Both CEQA and NEPA have undergone significant change since 2023. The summary must reflect the regime in effect when the document under review was prepared and note any subsequent change that affects litigation posture or follow-on administrative steps.
NEPA (federal)
- Statute: 42 U.S.C. § 4321 et seq., as amended by the Fiscal Responsibility Act of 2023 (Pub. L. 118-5, June 3, 2023).
- § 4336a codifies page limits (150 / 300 pages for EIS; 75 pages for EA), 2-year EIS / 1-year EA deadlines, lead/cooperating agency framework, and applicant-prepared documents.
- CEQ implementing regulations rescinded — formerly 40 C.F.R. Parts 1500–1508; rescinded effective April 11, 2025 (Interim Final Rule Feb 25, 2025; Final Rule Jan 8, 2026). Lead-agency NEPA implementing procedures now control.

environmental-impact-statement.
CEQA (California)
- Statute: Pub. Resources Code § 21000 et seq.
- CEQA Guidelines: 14 Cal. Code Regs. § 15000 et seq. — California Natural Resources Agency administering. Update pending following AB 130 / SB 131; expected early 2026. Verify current Guidelines version at draft time.
- AB 130 (signed June 30, 2025) — statutory CEQA exemption for qualifying infill housing projects on sites up to 20 acres; substantial streamlining.
- SB 131 (signed June 30, 2025) — companion process changes; expanded exemptions for advanced manufacturing and other categories.
- Earlier reforms: AB 1633 (2023, infill housing); AB 1307 (2023, noise from non-buyer-occupied housing); SB 423 (2023, SB 35 streamlining extension).
