AB 1603 California Assembly · 2025-2026 Regular Session

Perfluoroalkyl and polyfluoroalkyl substances (PFAS): Department of Pesticide Regulation.

Summary
Existing law generally regulates the use of pesticides, and requires every manufacturer of, importer of, or dealer in any pesticide, except as specified, to obtain a certificate of registration from the Department of Pesticide Regulation before the pesticide is offered for sale. Existing law requires a pesticide use report to be submitted to a county agricultural commissioner or the Director of Pesticide Regulation, as provided. This bill would require the department, on or before January 1, 2028, or on or before the posting of the pesticide use reporting database containing 2026 data, whichever occurs first, and annually thereafter, to indicate if a pesticide contains perfluoroalkyl and polyfluoroalkyl substances (PFAS) pesticide ingredients, as defined, in the pesticide use reporting database on its internet website, include PFAS as a category of interest for purposes of that database, and include pesticide use trends of PFAS pesticide ingredients from the pesticide database in the pesticide use annual report and other relevant pesticide use reporting documents. The bill would also require the department to, on or before January 1, 2028, publish a list of all registered pesticides that contain PFAS pesticide ingredients and submit this list to the commissioner of each county, and to, within 60 calendar days of the registration of a new pesticide containing PFAS pesticide ingredients, update the list on its internet website and submit the updated list to the commissioner of each county.

What changed between versions

08/30/26 - Enrolled AB1603 · 3 edits
MINOR
No substantive policy changes were made between these two versions. The difference is purely presentational: the formal enrolled bill document (with chapter heading, signature blocks, and page numbers) was replaced by a web page rendering of the same bill from the California Legislature website, which adds navigation elements, bill status history, and reformats the text for online display.
TECHNICAL

The formal enrolled bill document formatting (chapter heading, 'An act to amend' preamble block, page numbers, signature lines for Chief Clerk, Secretary of the Senate, Private Secretary of the Governor) was replaced by a web page layout with navigation menus, search tools, and bill status history.

Website navigation elements were added including skip-to-content links, home, accessibility, FAQ, feedback, sitemap, login, quick search fields, and links to related bill resources (votes, history, analysis, today's law as amended, compare versions).

Bill status and amendment history was added showing the full timeline from introduction on January 16, 2026 through enrollment on August 30, 2026, including all Assembly and Senate amendments.
