National Emission Standards for Area Sources of Hazardous Air Pollutants - “Area Source GACT Standards”

New rules are being developed to improve air quality by limiting the release of toxic chemicals into the air. Although your business may not have been impacted in the past by air quality rules and regulations, it is possible that it now will be affected. The new rules are not all the same; they differ by industry. It is important for you to research what is required of your business and learn how to stay in compliance. EPD is here to help you understand and comply with the rules.

Check to see if your business type is listed here 70 area source categories. If listed, your business may be impacted by new air quality rules and regulations.


Under the Urban Air Toxics Strategy, the Environmental Protection Agency (US EPA) is developing regulations to control toxic air pollutants from "area sources," that include neighborhood dry cleaners, auto collision and repair facilities, gas stations and others. Though emissions from individual area sources are often relatively small, together their emissions can be dangerous — particularly where large numbers of sources are located in heavily populated areas.

The Clean Air Act requires The US EPA to identify a list of at least 30 air toxic pollutants that pose the greatest potential health threat in urban areas. For the Urban Air Toxics Strategy, US EPA identified a list of 33 air toxics. This list is often referred to as the “urban air toxics.” US EPA must also identify and list the area source categories (business types) that represent 90 percent of these emissions and regulate them by specified standards (permit requirements) under the Clean Air Act. US EPA has identified a total of 70 area source categories, which represent 90 percent of the emissions of the listed air toxics.

For area sources within each business category, the Clean Air Act allows US EPA to develop standards or requirements which use "generally available control technologies or management practices" (GACT) rather than the more stringent "maximum achievable control technology" (MACT) required for major sources.

The Georgia Environmental Protection Division is responsible for implementing the area source standards in Georgia.

**Specific Industry Requirements: Initial Notifications, Initial Notifications of Compliance Status, and Notification of Compliance Status Forms

If your industry is listed in the 70 area source categories, please visit EPA's Air Toxics website for more specific information about which regulations apply to your business. In the table near the bottom of the page, locate your industry to find area source regulations that apply to you. Copies of the finalized regulations, initial notification and notification of compliance status examples, implementation information and brochures are also located here.

**Reporting Requirements

Most of the Area Source GACT regulations require you to submit an Initial Notification and/or a Notification of Compliance Status to the Georgia Environmental Protection Division and US EPA Region 4. Please see below for EPD and EPA contact information.
