Air Pollution Billing and Fees
Stationary Sources Program

  • APEN Filing Fee: $152.90
  • Annual Emission Fee:
    • $22.90/ton of criteria pollutant
    • $152.90/ton of hazardous air pollutant
  • Permit Processing Fee: $76.45/hour

Air Pollutant Emission Notice (APEN) Filing Fee:  A $152.90 filing fee is required for each APEN submitted, including APENs submitted for administrative changes (e.g., changes in ownership, change in location).

Annual Emission Fee:  State law requires all sources which are required to file Air Pollutant Emission Notice to pay an annual fee. The fee is based on the total annual emissions as reported on the most current Air Pollutant Emission Notice the Division has on file. Invoices for these fees will be mailed in May or June of each year. Current annual fees are $22.90 for each ton of criteria pollutants emitted and $152.90 for each ton of hazardous air pollutants emitted. These fees are subject to change by the legislature on a yearly basis.  Annual emission fees are administered by the Inventory and Support Unit .  

Permit Processing Fee:  In addition to the APEN filing fee and annual fee, the Division is required by law to recover the costs of operating the permitting program by charging applicants a processing fee. This fee is based on the amount of time it takes the Division to process the application according to an hourly rate and including costs such as publication of public notice. Processing fees are $76.45 per hour. The final approval fee includes the total of all costs associated with enforcement of the construction permit, compliance testing, and other costs as required for processing the permit.  Processing fees are charged for both initial and final approval permits, modifications, requested administrative changes and transfer of ownership. State law requires the Division to notify applicants in writing if total processing time (initial plus final) is anticipated to exceed 30 hours. In such cases, the Division must provide the applicant with an estimate of the projected processing time. Applicants may waive this notice requirement in writing when an application is submitted, if desired.
