AIR EMISSIONS REGULATIONS:

Air Quality Status All areas are in attainment
EPA's Nonattainment Areas
Major Source Threshold PTE 250 tons of any criteria pollutant triggers PSD; 100 tons/year triggers NSR
Minor Source Permitting Exemption See list below
Minor Source Treatment Opacity Limits
Emergency Generating Limits Can be operated for up to 90 days

DE MINIMIS EXEMPTIONS:

Units with emissions below the following limits will be considered exempt:

- 40 tons per year of CO
- 25 tons per year of VOCs, SO2, and NOx
- 15 tons per year of PM 2.5
- 10 tons per year of PM 10
- 1/2 ton per year of Pb
- 1 ton per year of HAPs
- 3 tons per year of any combination of HAPs

The following sources are considered to be insignificant but may be required to be listed in a permit application:
- Fuel burning equipment with a design rate less than 10 MMBtu/hr, provided that the aggregate pollutant emissions do not exceed 5 tons per year of any combination of Hazardous Air Pollutants (HAPs) and 10 tons per year of any other pollutant.
- Emergency use generators, boilers, or other fuel burning equipment that are equal to or smaller than the main unit, cannot be used with the main unit, and do not emit pollutants in excess of the main unit can operate for up to 90 days.

MINOR SOURCE PERMITTING:

A minor source permit is required for units that emit more than the exemption levels listed above. A minor source permit will include emission limits for criteria pollutants and HAPs as well as a fuel use or an operating limit to avoid major source permitting. An opacity limit of 5% for natural gas units and 20% for other units applies. No other limits are likely to be included.

There is a 30-day public comment period for new sources and the whole process (including comment period) takes no more than 3 months.

The department has created general permits for minor sources. However, there is currently no general permit available for electrical generation units. The state will charge around $200 per general permit and it will take about 10 days to receive the permit.

MAJOR NSR/PSD PERMITTING:

A potential to emit 250 tons or more of any criteria pollutant triggers PSD. A potential to emit 100 tons/year triggers NSR.

TREATMENT OF EMERGENCY ENGINES:

Emergency engines are treated the same as other units unless they meet the following limitation:
Emergency use generators, boilers, or other fuel burning equipment that is of equal or smaller capacity than the primary operating unit, cannot be used in conjunction with the primary operating unit, and does not emit or have the potential to emit regulated air pollutants in excess of the primary operating unit and not operated more than 90 days a year do not have to obtain a permit.

SITING REQUIREMENTS FOR NON-UTILITY GENERATORS:

The Arkansas Public Service Commission's siting authority is limited to publicly owned utilities. However, potential on-site electrical generation facilities are required to obtain any applicable air, water, or other environmental permits, and must comply with zoning regulations.

BUILDING, ZONING AND FIRE CODES:

The state legislature has adopted statewide building, fire and mechanical codes. They can be viewed by searching the state's Online Statute Database
