A Construction Permit is required for the installation of a new stationary source or modification to an existing source that is designated in Section 33-15-14.01.
True Minor—A true minor source Construction Permit is issued to facilities that have the potential to emit less than 100 ton/yr of a criteria pollutant, less than 10 ton/yr of any single hazardous air pollutant and less than 25 ton/yr of any combination of hazardous air pollutants.
General Permit— A general Permit to Construct may be issued to cover numerous, similar, true minor sources such as asphalt plants, dry cleaners and grain elevators.
Some sources or modification may represent such a minor impact to the air quality that a permit to construct is not required. In such cases, an application for a Construction Permit is required, at which point the Department will determine if a Permit is necessary. Should it be deemed that a Permit is not required, the Department will notify the source in writing as such.
Is modeling required?
Modeling may be required dependent on the amount and types of pollutants emitted by the source. Some source types may be exempt from modeling if they meet the criteria for exemption. For more information on exemptions, inputs, and modeling guidance see Modeling.
