Chemicals Selected by OEHHA for Consideration for Listing by the DART Identification Committee and Request for Relevant Information on the Reproductive Toxicity Hazards of: n-Hexane, Nickel and Nickel Compounds, PFOA and PFOS and their salts

The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) is the lead agency for the implementation of Proposition 65¹.  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 toxicity². The chemicals identified by the DARTIC are added to the Proposition 65 list.

OEHHA has selected the chemicals below for the DARTIC’s review for possible listing under Proposition 65.  OEHHA is initiating the development of hazard identification materials on these chemicals.

Chemicals Selected for Preparation of Reproductive Toxicity Hazard Identification Materials

Chemical	CAS No.
n-Hexane	110-54-3
Nickel and Nickel Compounds	---
Perfluorooctanoic acid (PFOA) and its salts	---
Perfluorooctane sulfonate  (PFOS) and its salts	---

These chemicals were selected using the procedure described in the document: “Process for Prioritizing Chemicals for Consideration under Proposition 65 by the State’s Qualified Experts.” This document is available here.

OEHHA selected these chemicals following consultation with the DARTIC in November 2015. 

Hazard identification materials for these chemicals will be presented at future meetings of the DARTIC for consideration of listing of the chemicals. 

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 n-hexane, nickel and nickel compounds, perfluorooctanoic acid (PFOA) and its salts, and perfluorooctane sulfonate (PFOS) and its salts.  Interested parties wishing to provide such information should send it to the address given below. 

The publication of this notice marks the start of a 45-day data call-in period, ending on Monday, April 4, 2016.  The information received during this period will be reviewed and considered by OEHHA as it prepares the reproductive toxicity hazard identification materials on these chemicals.

Hazard identification materials are made available to the public for comment prior to the DARTIC’s consideration of the chemical(s) for 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 are sent to the DARTIC for its consideration prior to the meeting at which the chemical(s) will be considered for listing.  OEHHA announces the time, date, location, and agenda of DARTIC meetings in the California Regulatory Notice Register and on its website.

We encourage you to submit relevant information responsive to this request in electronic form, rather than in paper form.  Submissions transmitted by e-mail should be addressed to P65Public.Comments@oehha.ca.gov.  Please include the chemical name in the subject line.  Comments submitted in paper form may be mailed, faxed, or delivered in person to the addresses below.
