Go to downloads

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 Carcinogen Identification Committee (CIC) 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 cancer[2].  The chemicals identified by the CIC are added to the Proposition 65 list. 

OEHHA has selected the chemical below for the CIC’s review for possible listing under Proposition 65.  OEHHA is initiating the development of hazard identification materials on this chemical.

By this notice, OEHHA is giving the public an opportunity to provide information relevant to the assessment of the evidence of carcinogenicity for coumarin.  Relevant information includes but is not limited to: 

  • Cancer bioassays
  • Cancer epidemiological studies
  • Genotoxicity testing
  • Other pertinent data on:
    • Pharmacokinetics
    • Biomarkers
    • Effects on biochemical and physiological processes in humans 

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 17, 2017.  The information received during this period will be reviewed and considered by OEHHA as it prepares the cancer hazard identification materials on coumarin. 

This chemical was selected using the procedure described in a 2004 document entitled: “Process for Prioritizing Chemicals for Consideration under Proposition 65 by the State’s Qualified Experts.”  This document is available on the Internet at http://oehha.ca.gov/media/downloads/proposition-65/document/finalpriordoc.pdf

OEHHA selected this chemical from those prioritized by the CIC in 2011.  For details, follow this link: http://www.oehha.ca.gov/prop65/public_meetings/cic101211synop.html

Hazard identification materials for coumarin will be presented at a future meeting of the CIC for consideration of listing under Proposition 65. 

Hazard identification materials are made available to the public for comment prior to the CIC’s consideration of the chemical(s) for possible listing.  The availability of 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 CIC 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 CIC 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 “coumarin” in the subject line.  Submissions in paper form may be mailed, faxed, or delivered in person to the addresses below:
