This permit is required prior to the construction or modification of any facility or emissions unit, which may emit the following air pollutants:

• Particulate Matter (PM)
• Sulfur Dioxide (SO2)
• Nitrogen Oxides (NOx)
• Carbon Monoxide (CO)
• Volatile organic compounds (VOCs)
• Lead
• Hazardous Air pollutants (HAPs)

The category of permit (Class A, B, or C) is dependent upon the volumes and types of emissions (before controls) as follows:

• C Source (less than 25 tons/year)
• B Source (equal to 25 tons/year but less than 100 tons/year)
• A Source (equal or more than 100 tons/year)

Some industry types or operations require Class A or B county air construction permits even if emissions are below the thresholds. Detailed information on these operations can be obtained by contacting the Air Facilities Section permitting staff at 305-372-6925.

In an effort to preserve air quality, industries and businesses that are sources of air pollution are regulated pursuant to Chapter 24, Code of Miami-Dade County, Chapter 403, Florida Statutes (F.S.), and Florida Administrative Code (F.A.C.) Rules 62-4, and 62-204 through 62-297.

Air permits are issued to regulated sources with enforceable terms and conditions under which the facility is required to construct/operate as mandated by Florida Department of Environmental Protection regulations and DERM rules.

Air pollution comes from many different sources such as factories, power plants, dry cleaners, cars, buses, trucks and even windblown dust and wildfires. Air pollution can threaten the health of human beings, trees, lakes, crops, and animals, as well as damage the ozone layer and buildings. Under the Clean Air Act, EPA sets limits on how much of a pollutant is allowed in the air anywhere in the United States.

Although national air quality has improved over the last 20 years, many challenges remain in protecting public health and the environment.

Facilities may require other types of permits depending upon the location, nature and size of the project. These may include, but are not limited to:

• Industrial Waste Permit
• Storage Tank Permit
• Tree Removal Permit
• Stratospheric Ozone Protection Permit
• Solid Waste Permit
• Liquid Waste Permit
• Industrial Waste Pretreatment

The Department shall issue a county air construction permit, or a determination that the requested permit be denied, within 8 working days of an application which has been deemed complete by the department.

The County Air Construction permit fees are based on the potential amount of air pollutants emitted by the facility. Please see DERM Fee Schedule

A County Air Construction permit shall be issued for a period of time sufficient to allow construction or modification of the facility or emissions unit and operation while the new or modified facility or emissions unit is conducting tests or otherwise demonstrating initial compliance with the conditions of the construction permit.

A County Air Construction permit is usually issued for a period of one (1) year.

If needed, the facility can request an extension. The facility shall apply for and receive a County Air Operating permit prior to the expiration of the County Air Construction permit for regular operation.

For more information, please call 305-372-6925.
