Chemicals Selected for Consideration for Listing by the DARTIC and Request for Relevant Information on the Reproductive Toxicity Hazards of: PFDA and its salts, PFHxS and its salts, PFNA and its salts, and PFUnDA and its salts

The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) is the lead agency for the implementation of Proposition 65[1].  The Developmental and Reproductive Toxicant Identification Committee (DARTIC) of OEHHA’s Science Advisory Board serves as the state’s qualified experts and renders an opinion about whether a chemical has been clearly shown to cause reproductive toxicity[2]. The chemicals identified by the DARTIC are added to the Proposition 65 list.

OEHHA has selected perfluorodecanoic acid (PFDA) and its salts, perfluorohexanesulfonic acid (PFHxS) and its salts, perfluorononanoic acid (PFNA) and its salts, and perfluoroundecanoic acid (PFUnDA) and its salts for the DARTIC’s review for possible listing under Proposition 65[3].  These chemicals were selected from chemicals prioritized by the DARTIC in 2020.  For details, follow this link:

OEHHA is initiating the development of hazard identification materials, for presentation at future meetings of the DARTIC for consideration of listing under Proposition 65.  By this notice, OEHHA is giving the public an opportunity to provide information relevant to the assessment of the evidence of developmental and male and female reproductive toxicity for PFDA and its salts, PFHxS and its salts, PFNA and its salts and PFUnDA and its salts.  Interested parties wishing to provide such information should submit it in accordance with the instructions given below. 

The publication of this notice marks the start of a 45-day data call-in period, ending on Monday, May 10, 2021.  The information received during this period will be reviewed and considered by OEHHA as it prepares the hazard identification materials on these chemicals.

Hazard identification materials will be made available to the public for comment prior to the DARTIC’s consideration of the chemical(s) for possible listing.  The availability of the hazard identification materials will be announced in the California Regulatory Notice Register and on OEHHA’s website.  Public comments received on these materials will be sent to the DARTIC for its consideration prior to the meeting at which the chemical(s) will be considered for listing.  OEHHA will announce the time, date, location, and agenda of DARTIC meetings in the California Regulatory Notice Register and on its website.

Because of limited in-office staffing during the COVID-19 emergency, OEHHA strongly recommends that relevant information responsive to this request be submitted electronically through our website at, rather than in paper form.  Comments submitted in paper form may still be mailed or delivered in person to the address below, but delays may occur if staff are unable to timely access them. 

All non-electronic submissions should be directed to:

Tyler Saechao
Office of Environmental Health Hazard Assessment
1001 I Street
P.O. Box 4010, MS-12B
Sacramento, California 95812-4010
Telephone: 916-445-6900

In order to be considered at this point in the process, the relevant information must be received at OEHHA by Monday, May 10, 2021.
