In Texas, air permit by rule or (PBR) is a permit that allows companies to produce emissions that are not believed to be substantial contributors to environmental contaminants. The Texas Commission on Environmental Quality (TCEQ) regulates air permit by rule in Texas. Not all air permits by rule in Texas require registration with the TCEQ to claim authorization. However, onsite documentation detailing emissions calculations, rules claimed, and recordkeeping must be maintained. The consultants at ESE Partners can help you determine if your operation is eligible for authorization under a PBR and what steps must be taken to obtain authorization.
