CAPCOA BACT Clearinghouse Resource Manual

I. Introduction

The primary purpose of this document is to assist district personnel, applicants, and consultants in the process of determining control technology requirements for given stationary source categories. Secondarily, this manual provides other types of assistance in the permitting process. By control technology, we refer to best available control technology (BACT) and lowest achievable emission rate (LAER). Most districts in California have not adopted BACT or LAER definitions directly out of the federal Clean Air Act or Code of Federal Regulations. An explanation of these differences is given in Sections VII and VIII. A tabulation of current BACT and LAER definitions used by California districts is provided in Section XI.

In preparing this document, a large amount of effort went into making it user friendly, especially to those unfamiliar with the California air pollution permitting program. In addition to information on control technology requirements for new and modified sources, this edition provides information on the California air pollution permitting program structure and permitting process. Such information may not be necessary to those familiar with the permitting process and the nuances of BACT and its application in California. It is important, however, that even knowledgeable users read Sections I through III before proceeding to use the compilation of determination information provided in Sections XIII and XIV.

To aid the less informed user, a glossary is provided in Section XII for terms commonly used in air pollution control. In addition, a list of acronyms and abbreviations is provided in the front section of the document.
