## Items pending verification in next review

- CA Natural Resources Agency CEQA Guidelines update (expected early 2026 per AB 130 / SB 131). Pin-cites to current Guidelines should carry `[VERIFY post-update]` until the revision is final.
- Lead-agency NEPA implementing procedure revisions (each agency's pace differs).
- Post-2025 CEQA case law applying AB 130 / SB 131 statutory exemptions.

## Notes on use

- A CEQA EIR prepared before June 30, 2025 was prepared under the pre-AB 130 / SB 131 regime. The summary describes what the document says; new statutory exemptions may apply to *future* projects but do not retroactively rewrite existing documents.
- A NEPA EIS prepared before April 11, 2025 was prepared under former 40 C.F.R. Parts 1500–1508. The summary describes the document as it exists; substantive hard-look review applies regardless of regime.
- For documents that span the regime change, identify the version of the rules in effect at NOI / Notice of Preparation and apply the document's contemporaneous regime in the summary.
