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.
