Industry Specific Assistance

Our emission calculators provide sector industry specific assistance in calculating emissions estimates from common air pollutants, such as VOC's, PM, PM10.  These calculated emissions help determine what type of air permit is needed. Listed below are various industrial category calculators to help determine your emissions. Also provided are compliance assistance tools, such as reporting and recordkeeping tools, to help you to comply with permit requirements.

Calculators

• 12 Month Rolling Sum Calculator (xlsx): Record Keeping/Reporting Tool for calculating 12-month rolling sum.
• Asphalt Emission Estimator (xlsx): This spreadsheet helps calculate a facility's potential to emit for asphalt plants.
• Concrete Batching Emission Estimator (xlsx): This spreadsheet helps calculate a facility's potential to emit for concrete plants.
• Fuel Combustion Calculator (xlsx): This spreadsheet calculates Criteria Pollutant emissions from combustion sources using emission factors.
• VOC and HAP Calculator (xlsx): This spreadsheet calculates VOC and HAP emissions using a material balance.
• Wood Working Emission Estimator - Combustion (xls): Calculates PM, PM10, PM2.5, VOC and NOX emissions from combustion sources using AP-42 emission factors.
• Wood Working Emissions Estimator - Surface Finishing (xls): Calculates PM, PM10, PM2.5, VOC and HAP emissions from paints, solvents, glues, etc. using a material balance.
• Wood Working Emissions Estimator - Wood Waste (pdf): Calculates PM, PM10, and PM2.5 emissions using the amount of waste collected and the capture efficiency of waste collection devices.

Reporting Tools
