Modeling and Effects Review Advisory Group

This Advisory Group is intended to provide APD staff with expanded knowledge and resources to meet existing and future issues related to air dispersion modeling and effects review related to the air permitting process.

The Modeling and Effects Review Advisory Group was established in October 2006 by the Texas Commission on Environmental Quality (TCEQ) Air Permits Division (APD). This group is an open participation group that meets on a periodic basis.

    • production and maintenance, startup and shutdown (MSS);
    • permits by rule;
    • standard permits.

  • Update of RG-25, Air Quality Modeling Guidelines to address:
    • new regulatory air dispersion models;
    • new National Ambient Air Quality Standards;
    • and effects reviews for Class I areas and Regional Haze.
  • Draft Modeling and Effect Review Applicability (MERA) guidance document:
