srp -- Meeting of the Scientific Review Panel on Toxic Air Contaminants Posted: 16 Oct 2008 17:33:16
This meeting of the Scientific Review Panel on Toxic Air Contaminants will occur on October 30, 2008 9:00 am . LOCATION: Millberry Conference Center University of California, San Francisco 500 Parnassus Avenue San Francisco, California 94143 (415) 476-2035 AGENDA 1. Continuation of the Panel’s review of the draft Reference Exposure Levels for acrolein, acetaldehyde, arsenic, mercury, manganese, and formaldehyde (September 2008) The Panel will continue its review of these RELs, developed utilizing the recently approved methods for developing acute, 8-hour, and chronic health protective levels (reference exposure levels [RELs]) used in non-cancer risk assessments. Pursuant to Health and Safety Code section 44360 (b) (2), OEHHA must develop health risk assessment guidelines under the Air Toxics Hot Spots Program. These guidelines include RELs. Some of the proposed RELS are new and others will replace older values. The new RELs address the mandate under the Children’s Environmental Health Protection Act (SB 25, Escutia, 1999; Health and Safety Code sections 39669.5 et seq.) to ensure that risk assessment methods adequately protect infants, children, and other sensitive subpopulations. The revised proposed RELs are located at http://www.oehha.ca.gov/air/toxic_contaminants/rels101008.html#srp (Transcript of the June, 18, 2008 meeting is available at: http://www.arb.ca.gov/srp/srpmeetings.htm) 2. Review of the draft report “Air Toxics Hot Spots Risk Assessment Guidelines Part II: Technical Support Document for Cancer Potency Factors” (October 2008) OEHHA will present a report containing revised methodologies for developing cancer unit risks and potency factors for chemicals in the Air Toxics Hot Spots program. This program (AB 2588, Connelly, 1998) requires stationary sources to report substances released into the air by collecting emission data to ascertain health risks. Pursuant to Health and Safety Code section 44360 (b) (2), OEHHA must develop health risk assessment guidelines under the Air Toxics Hot Spots Program. This document replaces and updates previous guidelines for cancer risk assessment by revising the procedures for deriving potency factors and applying cancer potency factors to address information that suggests that children may be especially susceptible to certain carcinogens. These procedures are designed to address the mandate under the Children’s Environmental Health Protection Act (SB 25, Escutia, 1999; Health and Safety Code sections 39669.5 et seq.) to ensure that risk assessment methods adequately protect infants, children, and other sensitive subpopulations. http://www.oehha.ca.gov/air/toxic_contaminants/rels101008.html#srp 3 Consideration of administrative matters.
