Air Pollution Control Guidance Document

The Air Permits Division has developed an air pollution control guidance document to assist permit reviewers during the technical review of permit applications.

This guidance document provides permit reviewers with a process to evaluate and determine air pollution control requirements. In addition, the document is available to the regulated community and the public to provide an understanding of air pollution control requirements and processes that affect air permit applications.

Specifically, the document provides guidance for completing case-by-case air pollution control technology reviews and also discusses control technology required by regulation or rule associated with the construction or modification of facilities (or emission units). These topics include the following:

  • Best Available Control Technology (minor source and major source Prevention of Significant Deterioration [PSD])
  • Lowest Achievable Emission Rate (LAER) (nonattainment major source
  • Reasonably Available Control Technology (RACT) (nonattainment source)
  • Maximum Achievable Control Technology (MACT) (major sources of hazardous air pollutants)
  • Generally Available Control Technology (GACT) (area sources of hazardous air pollutants)

NOTE: This guidance document is a training tool that is intended to replace previous guidance by clarifying policies and providing support for the implementation of rules in 30 TAC Chapter 116. While this document replaces all previous agency air pollution control guidance documents, including the April 2001 TCEQ Evaluating Best Available Control Technology (BACT) in Air Permit Applications (Draft), the October 30, 2000 Texas Natural Resource Conservation Commission Best Available Control Technology (BACT) (Draft), and the Best Available Control Technology (BACT) Tier III Cost Analysis guidance documents (Draft), it also brings forward and updates the “Control Technology” guidance document of the Texas Air Control Board (TACB) which was finalized in Spring 1987.

Public comments were received when the draft of this document was posted. View the comments and the response to comments.
