COSGROVE, KEVIN, and ORLANDO MAURICIO, Mittelhauser Corporation, Laguna Hills, CA

Compliance with the Air Toxics "Hot Spots" Information and Assessment Act of 1987, AB 2588, requires certain facilities to submit (1) a comprehensive air toxics emission inventory plan, and (2) an emission inventory report and risk assessment (for high-priority facilities).

The inventory plan shall include (1) a flow diagram identifying each actual and potential discrete emission point of release and the general location where fugitive emissions may occur; (2) a list of equipment and designation of the hazardous materials for which emissions are to be quantified; (3) quantification methods, and (4) reporting forms for each source as specified by the pending guidelines. Following agency approval, the emission inventory plan will be implemented and an air toxics emission report issued.

The Air Toxics Inventory Report (ATIR) presents procedures for estimating releases of toxics. This report must be prepared for reporting year 1989. Reporting forms shall be prepared pursuant to the requirements specified in Subchapter 7.6, Section 93322 of Title 17 of the CCR. These forms include Facility Description Form, Stack Data Forms, Device Description and Device-Stack Relations Forms, Process and Emittents Data Forms, and supplemental process parameter forms.

Following review of the emissions report air quality management districts, ARB, and the California Department of Health Services (DHS) will prioritize facilities and will consider (1) potency, toxicity, quantity, and volume of releases; (2) proximity of the facility to potential receptors; and (3) other factors that may indicate the facility poses significant risk.

High-priority facilities will be required to submit health-risk assessments. The health-risk assessment is a detailed, comprehensive analysis to evaluate and predict dispersion of hazardous substances, and the potential for human exposure.
