The Miami-Dade County Air Construction 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 the Environmental Resources Management 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, the U.S. Environmental Protection Agency (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
