Title V Fee Calculator - Air Permit Fee Estimation & Major Source Threshold Check
Estimate annual Title V operating permit fees and check 10/25/100 ton major source thresholds
Estimate annual Title V air permit fees based on your facility's actual or potential emissions. Enter emissions by pollutant to check major source thresholds (100 tpy criteria, 10 tpy single HAP, 25 tpy combined HAP), calculate the federal minimum fee per ton, and estimate your state-specific annual permit fee. Includes fee rates (verify current rates with your state agency) for all 50 states, fee cap lookups, and a threshold proximity warning system that flags pollutants within 80% of triggering major source status.

-
Enter Emissions by Pollutant
Input actual or potential emissions in tons per year for each criteria pollutant (NOx, SOx, PM, CO, VOC) and any hazardous air pollutants (HAPs). Use results from the fuel combustion or VOC calculators if available.
-
Select Your State
Choose your state to load the applicable fee rate and fee structure. Some states charge per ton of actual emissions, others use potential emissions, and some have flat fees plus per-ton charges.
-
Check Major Source Thresholds
The calculator automatically flags any pollutant that exceeds or approaches the 100 tpy criteria pollutant threshold, 10 tpy single HAP threshold, or 25 tpy combined HAP threshold.
-
Set Attainment Status
If your facility is in a nonattainment area for any pollutant, select the applicable nonattainment classification. Major source thresholds drop to 10-50 tpy in serious to extreme nonattainment areas.
-
Review Fee Estimate
See estimated annual Title V fee, per-pollutant fee breakdown, threshold proximity warnings, and comparison to the EPA minimum fee rate. Note that some states exempt certain pollutants or cap maximum fees.
Built For
- Environmental managers estimating annual air permit budget obligations
- Facility planners evaluating the cost impact of exceeding major source thresholds
- Consultants screening new projects for Title V applicability before construction
- Plant engineers calculating the fee savings from emission reduction projects
- Corporate environmental directors benchmarking permit costs across facilities
- Small business owners determining if expansion will trigger major source status
- Permit writers preparing fee calculations for annual compliance certifications
Assumptions
- Fee rates are based on publicly available state fee schedules and the federal minimum per-ton rate.
- Emission values entered represent actual or potential emissions as defined by the user.
- State-specific fee structures follow the most recently published schedule available.
- Major source thresholds use attainment-area defaults unless nonattainment is selected.
- Fee calculations do not include one-time application fees or permit modification fees.
Limitations
- State fee schedules change annually — always verify current rates with your state agency.
- Does not calculate potential to emit (PTE) — user must enter pre-calculated emission values.
- Some states exempt specific pollutants or apply fee caps not fully modeled here.
- Nonattainment area classifications and their specific thresholds may vary by pollutant.
- Does not estimate indirect compliance costs such as monitoring, testing, and reporting.
