Air Pollution Regulations and Laws

The Air Pollution Control District (APCD) enforces the laws and regulations that improve the air quality in Louisville and Jefferson County.

Laws” are what we usually call the acts, statutes, and ordinances passed by elected officials to govern an issue. Regulations are the rules created by a government agency, with input from the public, to implement those laws. For example, the Clean Air Act is a federal law that governs air pollution and requires that National Ambient Air Quality Standards be set. The specific standards are set in federal regulations.

Below are relevant local, state, and federal air pollution control laws and regulations.
