Air Quality - General Permits

Advantages to General Permits

  • Simplified application and permit issuance process
  • Standardized permit conditions providing consistency across industry sectors
  • Additional individual public notice and comment period not required
  • Flexibility to construct or modify equipment without a construction permit
  • Pre-determined eligibility criteria

Below is a list of the Bureau of Air Quality's current general permits:

Asphalt Plants (General Conditional Major)
Hot mix, warm mix, and cold mix asphalt plants may be eligible for a general permit if they only operate asphalt concrete production and the only sources of emissions are:

  • systems for receiving, storing, and transferring virgin aggregate;
  • systems for receiving, crushing, screening, storing and transferring non-virgin aggregate;
  • systems for receiving, storing, and transferring asphalt cement;
  • systems for mixing aggregate with asphalt cement;
  • systems for the storing and dispensing of asphalt;
  • asphalt cement and fuel storage tanks;
  • auxiliary heaters (including hot oil heaters) with a heat input rate less than million each; and
  • associated emission control systems.

Concrete Plants (General State Operating, General Conditional Major, General Construction)
Concrete batch plants, concrete block production facilities, and pug mills may be eligible for a general permit if they are only comprised of the following:

  • sand and aggregate storage;
  • sand and aggregate transfer to elevated bin;
