What Is a Permit?

A permit is a written authorization to build, install, modify, replace, remove, operate or handle equipment or material that emits or controls the emission of air pollutants, including:

  • Oxides of Nitrogen
  • Carbon Monoxide
  • Particulate Matter
  • Volatile Organic Compounds
  • Sulfur Dioxide
  • Asbestos
  • Air Toxics

Permits ensure that emission controls meet the needs of Louisville/Jefferson County to make steady progress toward achieving and maintaining federal air quality standards.

Any piece of equipment or project that emits or controls air pollutants requires a permit prior to installation and operation unless it is specifically exempted from APCD’s permit requirements. Companies must apply for and receive a permit before even purchasing new equipment to know exactly what the permit conditions and other requirements will be before construction, installation, and operation begin.

How Does the Permit System Work?

The permit system requires a review of the equipment design and an inspection of the installed equipment to ensure compliance with APCD regulations. APCD uses a two-permit system.

  1. Construction permits are required prior to beginning construction or modification of an affected facility or air pollution control equipment. APCD staff will review a proposed project for compliance with all applicable requirements.
  2. Operating permits are issued after the project is approved and completed and compliance is demonstrated.

APCD also issues other permits before the start of:

  • The demolition or renovation of structures with asbestos containing material
  • Recreational and agricultural open burning

Compliance must be demonstrated during and after the project is completed.
