Title: Development of toxics emission factors from source test data collected under the air toxics hot spots program

Principal Investigator / Author(s): Clark, Wyman

Contractor: Energy and Environmental Research

Contract Number: 92-338


Research Program Area: Emissions Monitoring & Control, Health & Exposure

Topic Areas: Stationary Sources, Toxic Air Contaminants


Abstract:

The California Air Resources Board sponsored a program to develop air toxic emission factors from source test data collected under the Air Toxics "Hot Spots" Information and Assessment Act of 1987 (AB 2588). Work for the project was divided into two phases. The purpose of Phase I was to collect all source tests prepared for AB 2588, screen each test, conduct a detailed validation on selected tests, develop emission factor calculation procedures and conduct a case study. Over 800 hundred source tests have been collected from a wide range of devices including asphalt dryers, boilers and heaters, reciprocating internal combustion engines, turbines, glass and metal furnaces, polystyrene reactors and coating and plating operations. During Phase II, emission factors were calculated from a selection of 200 priority tests for trace metals including hexavalent chromium, PCDD / PCDF, PAH and other SVOC, benzene, toluene and other VOC, aldehydes and HCI. A graphical user interface (GUI) was developed to display the emission factors. The GUI allows the user to sort, list, print and export emission factors from any emission factor group or combination of emission factor groups.
