Comment Period - Particulate Matter (as an air pollutant) and Total Trihalomethanes
The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) is the lead agency for the implementation of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). The Developmental and Reproductive Toxicant Identification Committee (DARTIC) of OEHHA’s Science Advisory Board advises and assists OEHHA in compiling the list of chemicals known to the State to cause reproductive toxicity as required by Health and Safety Code Section 25249.8. The Committee serves as the State’s qualified experts for determining whether a chemical has been clearly shown through scientifically valid testing according to generally accepted principles to cause reproductive toxicity.
The next meeting of the DARTIC to consider the potential listing of two chemicals is scheduled for Thursday, November 20, 2008. The meeting will be held at the California Environmental Protection Agency Headquarters Building, Sierra Hearing Room, 1001 I Street, Sacramento, California. The meeting will begin at 10:00 a.m. and will last until all business is conducted or until 5:00 p.m. The agenda for the meeting will be provided in a future public notice published in advance of the meeting.
On January 18, 2008, OEHHA requested information relevant to the assessment of the evidence of developmental and reproductive toxicity for hexavalent chromium and chlorpyrifos. The 60-day data call-in period ended on March 18, 2008. No information or data were received on hexavalent chromium. However, a significant volume of information was received on chlorpyrifos, which was evaluated by OEHHA staff. OEHHA has completed the hazard identification materials for hexavalent chromium and chlorpyrifos and announces the availability of the documents entitled: “Evidence on the Developmental and Reproductive Toxicity of Hexavalent Chromium,” and “Evidence on the Developmental and Reproductive Toxicity of Chlorpyrifos.” The DARTIC will use these documents at its November 20 meeting to consider whether hexavalent chromium and chlorpyrifos should be added to the Proposition 65 list as known to cause reproductive toxicity.
In addition, at the December 2007 meeting of the DARTIC, the Committee requested that OEHHA prepare a compilation of relevant studies for Particulate Matter (as an air pollutant) and Total Trihalomethanes, the same as had been prepared in 2007 for sulfur dioxide and bromodichloromethane. OEHHA is releasing the data compilations for public comment. The comment period will close on Tuesday, November 4, 2008. The DARTIC will provide advice to OEHHA concerning whether to proceed to develop hazard identification materials for consideration of these chemicals for presentation at a future meeting. No listing decisions concerning particulate matter or trihalomethanes will be made at the November 20 meeting.
