California may add BPA to Prop. 65 list.

On Friday, California’s Office of Environmental Health Hazard Assessment (OEHHA) announced that bisphenol A (BPA), a chemical found in common consumer products like food packaging and paper receipts, will be considered for possible listing under the state’s Proposition 65 program, which requires businesses to provide warnings for exposures to listed chemicals. The Developmental and Reproductive Toxicant Identification Committee (DARTIC), an advisory panel that helps OEHHA compile the list of chemicals known to cause reproductive toxicity, will meet on May 7, 2015 to “consider whether BPA has been clearly shown by scientifically valid testing according to generally accepted principles to cause female reproductive toxicity.”

In April 2013, BPA was added to the Prop. 65 list as a reproductive toxicant for development endpoints via the Prop. 65 “authoritative bodies” mechanism, based on the National Toxicology Project’s findings that BPA caused reproductive toxicity at high doses. However, California delisted BPA the next week, in response to a lawsuit brought by the American Chemistry Council, and simultaneously withdrew that attempt to list the chemical.

DARTIC will now be revisiting BPA per a 2009 request from the committee to reconsider the chemical “if additional epidemiological or other specific types of data on reproductive and developmental toxicity became available.” Substantial relevant data has become available since 2009, including a significant 2014 review of studies published from 2007-2013 concluding that BPA is a reproductive toxicant.

OEHHA has compiled hazard identification materials on BPA and female reproductive toxicity for the consideration of both DARTIC and the public. The agency is accepting comments on the hazard identification materials through April 6, 2015. These comments will be forwarded to DARTIC members before the May 7 meeting, and also posted online. Instructions for submitting comments are in the meeting notice.

The May 7 meeting will begin at 10:00am in the Coastal Hearing Room of the Cal/EPA Headquarters building, 1001 I Street, Sacramento, and will also be webcast. If DARTIC require more time for deliberations, the meeting will be continued on May 21 at the same location.
