Comment Period - Notice of Intent to Change the Basis for Listing as Known to the State of California to Cause Reproductive Toxicity: Dichloroacetic Acid

OEHHA has reviewed the studies or study descriptions cited by U.S. EPA (2003a,b) in support of its conclusions regarding the male reproductive and developmental toxicity of DCA, relative to the criteria in Section 25306(g). The criteria for listing DCA as known to cause reproductive toxicity (male reproductive and developmental endpoints) by the authoritative bodies mechanism have been met. Therefore, OEHHA has determined that DCA must stay on the Proposition 65 list.

Request for comments: OEHHA is requesting comments as to whether this chemical meets the criteria set forth in the Proposition65 regulations for listings via the authoritative bodies listing mechanism (Section 25306) and should, therefore, remain on the list of chemicals known to the State to cause reproductive toxicity, with the additional endpoint of developmental toxicity.

In order to be considered, comments must be received by OEHHA by 5:00 p.m. on MONDAY, October 21, 2013. We encourage you to submit comments in electronic form, rather than in paper form. Comments transmitted by e-mail should be addressed to P65Public.comments@oehha.ca.gov. Please include “Dichloroacetic acid” in the subject line. Comments submitted in paper form may be mailed, faxed, or delivered in person to the address below:

  Intent to change the basis for the listing of dichloroacetic acid as known to the state to cause reproductive toxicity under the Safe Drinking Water and Toxic Enforcement Act of 1986.  Dichloroacetic acid was listed based on its identification as causing male reproductive toxicity in the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs). The proposed new mechanism for listing is via the authoritative bodies mechanism.
