STATE OF CALIFORNIA AIR RESOURCES 1103 O STREET P.O. SOX 1815 SACRAMENTO. CA 95812 BOARD GEORGE DEUKMEjtAN Ocwmc April 4, 1985 Dear Sir or Madam: Subject: Request for Information Regarding Vinyl Chloride I am writing to request information on the health- effects of vinyl chlorine as part of our toxic air contaminant program. This program is based on Health and Safety Code Sections 39650, et seq. which require the ARB to identify compounds as toxic air contaminants and once identified to develop and adopt control measures for such compounds. After consultation with the staff of the Department of Health Services (DHS), we have selected vinyl chloride as a candidate toxic air contaminant to be evaluated in accordance with the provisions of Health and Safety Cooe Sections 39650, et seq. During our evaluation of vinyl chloriae, we will consider all available health information regarding this compound. Additionally, we are soliciting information regarding possible biological production of vinyl chloride. Before the ARB can formally identify a compound as a toxic air contaminant, several steps must be taken. First, the ARB must request the Department of Health Services to evaluate the health effects of candidate compounds. Second, the ARB staff must prepare a report which includes the health effects evaluation and then submit the report to a Scientific Review Panel for its review. The report submitted to the Panel will be made available to the public. Information submitted In response to this request will be considered in the ARB report to the Panel. Although any person may also submit information directly to the Panel for its consideration, I urge you to submit all information at this time for our consideration in the development of the report for the Panel. The Panel reviews the sufficiency of the information, methods, and data used by the DHS in its evaluation. Last, after review by the Scientific Review Panel, the report with the written findings of the Panel will be considered by the Air Resources Board and will be the basis for any regulatory action by the Board officially to identify a compound as a toxic air contaminant. Prior to formally requesting the DHS to prepare a health effects evaluation of vinyl chloride, we are providing, pursuant to the provisions of CMA 007333 April 4, 1965 If you are not the person to whom this request should be addressed, please forward it to the appropriate person in your organization. Also, please let us know whether you would like to continue to receive information inquiries for other candidate compounds, and if not, if there is anyone in your organization to whom such requests should be sent.
