NOTICE OF PUBLIC MEETING

The Scientific Review Panel on Toxic Air Contaminants (Panel), established pursuant to California Health and Safety Code section 39670, will hold a public meeting at the following time and place:

DATE: November 28, 2001

—— 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 further discuss the chronic reference exposure levels for 13 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.

    *Acrylonitrile, beryllium (and beryllium compounds), chloropicrin, diethanolamine, ethylene dibromide, ethylene glycol butyl ether, isophorone, maleic anhydride, methyl isocyanate, methylene dianiline, selenium and selenium compounds (other than hydrogen selenide), sulfuric acid, and

    vinyl acetate.

  2. Consideration of findings relating to the Panel’s review of the report: "Prioritization of Toxic Air Contaminants under the Children’s Environmental Health Protection Act" (SB 25, [Escutia] 1999)

    The Panel will discuss and consider adopting findings based on its review of this report. In its

    July 30, 2001 meeting the Panel found the report to be based on sound science, as required by law, and accepted a proposed list of five contaminants that may disproportionately impact infants and children – acrolein; particulate emissions from diesel-fueled engines; chlorinated dioxins and dibenzofurans; lead and lead compounds (organic and inorganic); and polycyclic organic matter.

  3. Update on risk assessment of cholinesterase inhibiting compounds

    Department of Pesticide Regulation and OEHHA staff will give a progress report on their joint effort to develop guidelines for addressing organophosphate pesticides in risk assessments as requested by the Panel.

  4. Panel administrative matters

The Panel may discuss administrative matters, including upcoming topics and meeting dates.

 

THE AGENDA ITEMS LISTED ABOVE MAY BE CONSIDERED IN A DIFFERENT ORDER AT

THE PANEL MEETING

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). 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 the Office of Environmental Health Hazard Assessment (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 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. Transcripts to previously held Panel meetings can be found through the ARB web site www.arb.ca.gov/srp/srp.htm.
