Summary
California AB 93 would have required data center owners or operators to give their water supplier a water-use estimate before an initial business license and to self-certify water reporting at initial licensing and renewal. The Governor announced its veto on 11 October 2025, so it did not become law. A later bill on a similar subject, AB 2619 of 2026, was enacted as chapter 437 and is a separate record.
What this does not establish
- The primary source is the Governor's 11 October 2025 legislative update listing the veto; the linked veto-message PDF has no text layer and was not transcribed.
- The enrolled text comes from an earlier review's extract of the official bulk file pubinfo_2025.zip; the saved copy was checked as unchanged.
- The later AB 2619 (Statutes of 2026, chapter 437) is a separate, enacted instrument and does not revive AB 93.
Unresolved questions
None recorded.
Relationships
Supersession means a later instrument replaces the earlier legal effect. Repeal links identify the repeal instrument and the measure it ends. A later implementation or related letter is not treated as a replacement unless the record says so.
- No related action is recorded.
