Air Quality - Fees

The Department bases annual air quality fees on the tons of air emissions generated by a facility. Note that DHEC does not assess fees for air permit applications, renewals, or revisions, except for fees assessed for the voluntary expedited permitting program.

To determine a facility's annual fee, DHEC multiplies the billable emissions generated by a facility by the yearly fee rate (see the table below). As specified in Federal and State regulations, the fee rate is adjusted each year based on the Consumer Price Index. Facilities with emissions less than one ton are assessed a minimum fee based on one ton of emissions.

Air Fee Rate
Fiscal Year (July 1 – June 30) Fee Rate (cost/ ton billable emissions)
2021 $52.03
2020 $51.06
2019 $49.85
2018 $48.88

Any facility that holds a valid air permit on July 1 is subject to annual fees.  If a facility is permanently closed (ceased all operations) and no longer requires an air permit, the facility must inform DHEC of the closure prior to July 1. Otherwise, the facility will be assessed air quality fees for the entire fiscal year period (July 1 - June 30). A facility that has idled but chooses to maintain its permit is still subject to fees. 

Title V Sources

For Title V sources, fees are based on actual emissions of billable pollutants from the facility’s emissions inventory report. The emission inventory accounts for all emissions from a facility by using various methodologies, such as stack test data, established emission factors, equipment manufacturers' data, production rates, etc. DHEC's Emissions Inventory Section reviews the information submitted by a facility to ensure that the facility has included all sources and used appropriate calculation methodologies.

All regulated pollutants, except carbon monoxide and carbon dioxide equivalents, are included in this billing determination. Pollutants that are Federal Hazardous Air Pollutants (HAPs) or State Toxic Air Pollutants (TAPs) and also VOCs or particulate matter are only billed once, even though these pollutants may be tracked separately in the inventory.

In addition to the cost per ton fee rate described above, Title V facilities are required to pay a maintenance fee per the following table.

Total Billable Emissions Maintenance Fee

< 10 tons

$500.00

10 - 50 tons

$1,000.00

> 50 - 100 tons

$2,000.00

> 100 - 250 tons

$3,500.00

> 250 - 1000 tons

$6,500.00

> 1000 tons

$10,000.00

The total annual fee for each Title V facility is the sum of the billable emissions at the cost per ton rate and the maintenance fee.


Conditional Major Sources

Conditional Major and General Conditional Major sources are not required to provide DHEC with emissions inventory data. Emissions for these sources are based on the facility’s Standard Industrial Classification (SIC) categories. DHEC uses the SIC code to assign the average tons of emissions for each facility based on a review of the permit. The assigned tons of emissions are multiplied by the yearly fee rate to determine the annual fee.

Minor Sources

Minor and State Major sources are also not required to provide emission inventory data. Emissions from these sources are based on industry averages. Based on a review of the permits, Department staff have identified the industry average emissions and assigned them for each facility.  The assigned tons of emissions are multiplied by the yearly fee rate to determine the annual fee.

New Sources

New sources are subject to new source fees for the Fiscal Year in which they began operating. Emissions Inventory staff will contact new sources to explain the fee determination based on facility type. New source fees are used for billing until the annual Air permit fees described above are applicable.
