UPDATE: AQD-022 and AQD-023
The Air Quality Division has recently updated two Policy and Procedure Documents that are used internally and externally. The two updated documents are AQD-022: Dispersion Modeling Guidance for Federally Regulated Pollutants and AQD-023: Replacement of Engines, Compressors, or Turbines as Part of a Normal Maintenance Program at Landfill Gas-To-Energy Facilities.
