South Coast Air Quality Management District

Set a Public Hearing to Amend Rule 1401 - New Source Review of Toxic Air Contaminants, and Report on Impacts Relative to Sources Subject to Rule 1402 - Control of Toxic Air Contaminants from Existing Sources. In September 2002, the state Office of Environmental Health Hazard Assessment finalized chronic risk values for two compounds. Rule 1401(e)(2) and (e)(3) require an analysis and report to the Board before new and updated risk factors, respectively, are used for air toxics new source review. Proposed amendments to Rule 1401 will update the list of compounds and effective dates in Table I. The amendments will also include a proposal to move to an annual update of state approved risk factors instead of the current 150-day requirement. In addition, Rule 1402(j)(4) requires an analysis of the potential impacts on sources subject to Rule 1402 prior to use of new or updated risk factors for facility-wide health risk assessments. (Review: Stationary Source Committee, November 22, 2002)

The complete text of the proposed amendments, staff reports and other supporting documents will be available no later than December 11, 2002, from the District’s Public Information Center, (909) 396-2550 and on the Internet (www.aqmd.gov).
