The Scientific Review Panel (SRP/Panel) is charged with evaluating the risk assessments of substances proposed for identification as toxic air contaminants by the Air Resources Board (ARB) and the Department of Pesticide Regulation (DPR). In carrying out this responsibility, the SRP reviews the exposure and health assessment reports and underlying scientific data upon which the reports are based, which are prepared by the ARB, DPR, and the Office of Environmental Health Hazard Assessment (OEHHA) pursuant to Health and Safety Code Sections 39660-39661 and Food and Agriculture Code Sections 14022-14023. These reports are prepared for the purpose of determining whether a substance or pesticide should be identified as a toxic air contaminant. The SRP welcomes written comments or submissions from all parties regarding a report. To assure adequate review, the SRP does not accept written or oral comments from the public at its meetings; comments and submissions should be submitted to the ARB pursuant to the requirements specified in the notice of availability of a report for public review. These submissions are received and carefully reviewed and considered by the Panel members prior to the public meeting.
