Water discharge: commercial, industrial, or institutional sites.

Added new Water Code Section 13383.4 defining 'CII site' as a privately owned parcel or contiguous parcels that are commercial, industrial, or institutional based on county tax assessor land use codes. For mixed-use parcels, only the non-residential portion qualifies. Residential facilities of any type are explicitly excluded, even within mixed-use parcels.

Removed the nonsubstantive amendment to Water Code Section 13100 (regarding the State Water Resources Control Board's organization and membership).

Fiscal committee vote changed from 'no' to 'yes,' meaning the bill now requires a fiscal committee review, likely due to the new CII site definition potentially affecting stormwater permitting costs or compliance obligations.

New Section 1 amends Water Code Section 1342 to reduce the required mailing notice period for unprotested water appropriation hearings from 20 days to 15 days before the hearing date. This shortens the window in which the public can learn about and respond to a proposed water appropriation permit.

The fiscal committee designation changed from 'no' to 'yes,' meaning the bill now requires review by the Assembly Fiscal Committee, suggesting the amendment introduced potential state fiscal impact.

The original Section 1 (nonsubstantive cleanup of Water Code Section 13100 regarding the State Water Resources Control Board) was renumbered as Section 2 and had a stray period removed at the end of the provision.
