Posted: 21 Nov 2008 14:42:22
Meeting of the Scientific Review Panel on Toxic Air Contaminants: December 5, 2008 8:00 am. LOCATION: Tom Bradley International Hall http://www.ucla.edu/map University of California, Los Angeles 417 Charles E. Young Drive, West Los Angeles, California 90095-1317 (310) 825-7021 AGENDA 1. Continuation of the Panel’s review of the draft Reference Exposure Levels for acrolein, acetaldehyde, arsenic, mercury, manganese, and formaldehyde (December 2008) The Panel will continue its review of these reference exposure levels (RELs) developed utilizing the recently approved methods for developing acute, 8-hour, and chronic health protective levels RELs used in non-cancer risk assessments. Pursuant to Health and Safety Code section 44360 (b) (2), the Office of Environmental Health Hazard Assessment (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. Upon completing its review, the Panel will prepare its findings and submit them to the OEHHA Director. The revised proposed RELs will be posted prior to the meeting at: http://www.oehha.ca.gov/air/toxic_contaminants (Transcript of the October, 30, 2008 meeting is available at: http://www.arb.ca.gov/srp/srpmeetings.htm) 2. Continuation of the Panel’s review of the draft report “Air Toxics Hot Spots Risk Assessment Guidelines Part II: Technical Support Document for Cancer Potency Factors” (December 2008) The Panel will continue its review of the 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 and applying cancer potency factors to address information that suggests that children may be especially susceptible to certain carcinogens. These procedures 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 report will be posted prior to the meeting at: http://www.oehha.ca.gov/air/toxic_contaminants 3 Consideration of administrative matters.
