Air-related Permits-DRAFT

The department issues a variety of air permits to businesses and individuals that have the potential to emit air pollution through industrial processes or open burning. Permits describe how a facility is required to meet state and federal air quality regulations to reduce air pollution and protect public health. The permit also documents all sources of air pollution at the facility, what pollutants will be released, how much is released and what steps the permittee is required to take to reduce pollution.

Construction Permits

Construction permits, also called New Source Review permits, are required for the construction of a new air pollution source, or modification of an existing source. Construction and modifications refer to activities that will increase air emissions and include changes in operation, addition of equipment, changes in fuel or raw materials and the relocation of previously permitted sources. Certain activities have been determined by the state to be a source of insignificant emissions and are exempt from permitting requirements per 10 CSR 10-6.061.

Air Permits-by-Rule Construction Permit

• If your business operates a printing operation, crematory or animal incinerator, surface coating or livestock market, you may require an Air Permit-by-Rule Construction Permit to address potential air emissions. By applying for this permit rather than a De Minimis or Minor Construction Permit, your business agrees to certain conditions of operation.

Air Major Construction Permit Sections (7), (8) & (9)

• If your business plans to construct a new installation or modify an existing minor installation and the project has the potential to emit more than major emission levels of a regulated air containment or construct a new installation or modify an existing major installation and the project has the potential to emit more than the minor levels per year, you may require an Air Major Construction Permit Sections (7), (8) & (9) to address potential air emissions.

Air Minor Construction Permit Section (5)

• If your business plans to construct a new installation or modify an existing minor installation and the project has the potential to emit less than major source levels per year; or you plan to construct a new installation or modify an existing major installation and the project has the potential to emit less than the minor levels per year, you may require an Air Minor Construction Permit Section (5) to address potential air emissions.

Air Portable Relocation Construction Permit (Section 4)

• If your business plans to relocate an industrial emission source designed for and capable of being moved to other sites around the state, you may need an Air Portable Relocation Construction Permit Section (4) to address potential air emissions. This equipment typically includes portable concrete, asphalt or crushing plants that have been previously permitted as a De Minimis/ Minor installation.

Air Temporary/ Pilot Construction Permit Section (10)

• If your business plans to construct a temporary installation or pilot plant with the potential to emit less than 100 tons of each pollutant per year, you may require an Air Temporary/ Pilot Construction Permit Section (10) to address potential air emissions.

Operating Permits

Operating permits are required for any air pollution source that has the potential to emit pollutants in excess of the major source thresholds. An operating permit identifies all applicable requirements. Operating permits include information on which pollutants are being released, how much is released, and what steps, if any, that the facility is required to take to reduce the pollution.

Part 70 Operating Permit

• If your business has the potential to emit greater than 100 tons per year of any regulated pollutant, has the potential to emit greater than 100 tons per year of any single hazardous air pollutant, or greater than 25 tons per year of combined hazardous air pollutants, or is required by a New Source Performance Standard or a Maximum Achievable Control Technology, you may require an Air Part 70 Operating Permit.

Intermediate Operating Permit

• If your business is required to obtain a Part 70 Operating Permits but accepts voluntary, practically enforcement limitation to reduce emissions to less than 100 tons per year of any regulated pollutant and is less than 10 tons per year of any single hazardous air pollutant and less than 25 tons per year of any combined hazardous air pollutant, you may require an Air Intermediate Operating Permit to address potential air emissions.
