CAPCOA BACT Clearinghouse Resource Manual

This page last reviewed April 5, 2017


The information in this document is meant for use by those involved in determining control technology requirements for stationary sources undergoing new source review. A list of such parties includes California air pollution control and air quality management districts (APCDs and AQMDs, respectively), public agencies, applicants, and consultants. The layout of this document is meant to complement the Best Available Control Technology Guideline published by the South Coast Air Quality Management District (SCAQMD). Much attention was given to using consistent source categories. Where the SCAQMD guideline catalogs current information on potential best available control technology (BACT) requirements, this document provides a tabulation of information on previous determinations.

Down through the years, the BACT clearinghouse has become increasingly computerized. One may now download this document or its future revisions using the California Air Resources Board Information System (CARBIS) by accessing the worldwide website at /bact/bact.htm. A searchable electronic database is also available at the same website. In the future, we wish to also have remote computer entry for submittal of BACT determination forms to the clearinghouse. Currently, however, forms may be submitted on hardcopy forms. If you wish, we can provide a forms and a manual explaining how to submit information to the BACT clearinghouse.

We wish to thank member APCDs of CAPCOA that have made this document possible through their contribution of information on BACT and lowest achievable emission rate (LAER) determinations. Without their efforts, the clearinghouse could not exist. Furthermore, we encourage the participation of APCD personnel in providing the CAPCOA BACT clearinghouse with new information on determinations when available. In addition, any suggestions regarding submittal procedures or publication of determination information can be addressed to Bob Giorgis of the Project Support Section, California Air Resources Board by phone at (916) 327-5601, by e-mail at, or by mail to the following address:
