California AB 1603: What Pesticide Registrants Need to Know About New PFAS Disclosure Requirements
California Assembly Bill 1603 amends the Food and Agricultural Code by directing DPR to take several concrete steps no later than January 1, 2028 to identify and disclose PFAS pesticide ingredients in California-registered pesticides. DPR must now flag whether each registered pesticide contains PFAS pesticide ingredients in its online pesticide use reporting database, designate PFAS as a searchable category of interest within that database, and incorporate PFAS pesticide use trends into its annual pesticide use report and related reporting documents on an ongoing basis. Separately, DPR must compile and publish on its website a complete list of all registered pesticides containing PFAS pesticide ingredients and deliver that list to every county agricultural commissioner in California. After the initial publication, DPR is required to update the list and redistribute it to all county commissioners within 60 calendar days whenever a new PFAS-containing pesticide is registered.

Representative Matters
- Climate Change Litigation. Argued in the D.C. Circuit on behalf of the largest U.S. aircraft manufacturer, defending EPA’s first-ever regulation of aircraft greenhouse gas (GHG) emissions. We also submitted an amicus brief to the Supreme Court on behalf of the electric industry and a national water association urging the Court to preserve EPA’s regulatory authority over GHGs in one of the highest-profile environment and climate change case of the year.
- Contamination & Site Remediation. Representing industrial companies in their high exposure and legacy liability CERCLA matters involving the most complex sites across the country, including contaminated river sediment sites and multifaceted landfill sites, covering dozens of parties, and remedies in the hundreds of millions of dollars per site. Our work encompasses strategic counseling, allocation mediation proceedings, direct negotiations with DOJ, EPA, natural resource trustees, and other federal agencies, third party recovery, and litigation when necessary.
- PFAS Investigation & Enforcement. Defending a major chemicals company in engaging with EPA and DOJ regarding historic PFAS use and disposal.
- Energy Project Defense. Defending the municipal water agency serving Denver from CWA, NEPA, and ESA claims challenging a critical hydropower and dam/reservoir expansion project, and sued to bar a county from using a local permit process to block the project, obtaining a settlement allowing the project to proceed.
- Renewable Fuels Enforcement. Challenged a $70+ million civil penalty imposed by EPA on a renewable fuels generator, winning a stay from the Sixth Circuit and negotiating a favorable settlement.
- Crop Protection Products Litigation. Representing leading crop protection companies and national trade associations across a docket of litigation challenging product registrations under FIFRA, the Endangered Species Act, and CEQA in federal and state trial and appellate courts.
- Chemical Regulatory and Enforcement Counseling. Represented a producer of drinking water preservatives, settling an allegation of required labeling violations under California’s Food and Agriculture Code under the Department of Pesticide Regulation.
- Electric Vehicle Supplier Product Counseling. Counseling an EV supplier on mobile source and other regulations affecting its business, including EPA and California greenhouse gas requirements, import-export matters, and EV credits.
