—AGENDA—

1. Discussion of substances to be included in the Air Toxics Hot Spots Program Risk Assessment Guidelines, Part III: Technical Support Document "Determination of Noncancer Chronic Reference Exposure Levels"

   In this meeting the Panel will discuss the chronic reference exposure levels for five substances* proposed to be included in the Part III guideline document by the Office of Environmental Health Hazard Assessment (OEHHA) staff. Part III describes the methods used to determine chronic reference exposure levels, at (or below) which no adverse health effects are anticipated from exposure to the listed chemicals. Once approved by the Panel, these substances become an addendum to the original report approved by the Panel in February 2000.

   *carbon disulfide, fluorides (including hydrogen fluoride), methyl ethyl ketone, phosphine, and triethylamine.

2. Consideration of the revised report: "Evaluation of Methyl Isothiocyanate as a Toxic Air Contaminant." (January 2002)

INFORMATION ABOUT

THE SCIENTIFIC REVIEW PANEL

The Scientific Review Panel (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), and the review of guidelines prepared by the Office of Environmental Health Hazard Assessment (OEHHA). In carrying out this responsibility, the Panel reviews the exposure and health assessment reports and underlying scientific data on which the reports are based, which are prepared by the ARB, DPR, and OEHHA pursuant to Health and Safety Code sections 39660-39661, 39669.5 and 44360, and Food and Agricultural 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, or as guidelines to be used in preparing health risk assessments. The Panel welcomes written comments or submissions from all parties regarding a report. To assure adequate review, the Panel does not accept oral comments from the public at its meetings, and requests that information submitted for its consideration be submitted to the Panel Liaison (contact information below) prior to the meeting. These submissions are received and carefully reviewed and considered by the Panel members prior to the public meeting. Transcripts to previously held Panel meetings can be found through the ARB web site www.arb.ca.gov/srp/srp.htm.
