IMPORTANT: As of July 1st, 2011, functions once performed by the Wisconsin Department of Commerce have been moved to other state agencies and the Wisconsin Economic Development Corporation. The former Commerce web site will continue to exist for the next several months as resources are moved to new web site locations. We will make every attempt possible to direct our users to the new locations as web resources are moved.

Small Business Clean Air Assistance Program

Air Toxics or Hazardous Air Pollutants

Important note! The Small Business Clean Air Assistance Program is moving. Beginning July 1, 2011, the SBCAAP will be located in Wisconsin's Department of Natural Resources. For the new address and phone numbers, see the Contact Information at the bottom of our program home page.

Both US Environmental Protection Agency (EPA) and Wisconsin Department of Natural Resources (DNR) have regulations affecting emissions of air toxics, which are also called hazardous air pollutants. The regulations created by each agency are very different in the way they apply to businesses. There is a provision in the DNR regulation that where a business has to reduce emissions of certain hazardous air pollutants (HAPs) under EPA's rules, then that business does not have to apply DNR's regulations to those same hazardous air pollutants. Because the DNR and EPA do not regulate the exact same hazardous air pollutants, you should review both sets of rules to see whether they affect your business.


  State Regulations

Chapter NR 445, the State Hazardous Air Pollutant Rule

NR 445 (Hazardous Air Pollutant Rule) revisions became final July 2004. As of July 1, 2004, new sources (including modified sources) were to be in compliance with the new rule upon startup of the new or modified processes. Existing sources had until July 1, 2007 to comply with the rule. Information on the rule and how it might apply to a company can be found on the Air Toxics web page *.

Under the revised rule, there is an option to use a simple computer model to show a facility can meet the rule and avoid submitting a lot of paperwork to DNR. SCREEN3 is the name of the simple computer program that can be used as a tool to see if you may already be in compliance with the hazardous air pollutant rule. There are detailed instructions you will need to use this program, but the program itself is a very small and self-contained program that you install on your own hard drive. The modeling program can be found on EPA's website at www.epa.gov/ttn/scram/ disperson_screening.htm *, and you'll want to download the SCREEN3 model.

For further information about this requirement, you may also contact:

Federal Regulations

The EPA is required under s. 112, Clean Air Act, to write rules called MACT (Maximum Achievable Control Technology) standards as part of their National Emissions Standards for Hazardous Air Pollutants program. The MACT standards are generally applied to major sources.

In the next couple years Area Source rules for National Emission Standards for Hazardous Air Pollutants will also be developed. These rules may use MACT standards or GACT (Generally Achieveable Control Technology) depending on factors related to the ability of the smaller sources to install controls or whether best management practices are used. 

  Status of MACT Rules

All MACT rules are final and many sources should be in compliance at this time. Check EPA's Air Toxics website for detailed information about all the MACT rules issued by EPA.

EPA has been order to complete Residual Risk evaluations of existing NESHAPs over the next couple years, so changes may affect older rules soon. Those changes will be posted here as well.

  Status of Area Source Rules

EPA started issuing rules for area source categories in December 2006. As of June 2010 the area source rules are nearly complete. One remaining category is in negotiations: brick and clay manufacturing.

Copies of proposed and final rules are found in the Rules/Notices Table on EPA's Area Source Rule Page. If no links are included below for a rule, you may find implementation tools and example forms provided for these rules as they are developed on EPA's Area Source Rule Page in the Tables titled Implementation Tools and Initial Notification Examples.

All Notifications for these rules should be sent to both of the following addresses. It's recommended you use certified mail or similar service to ensure the form was received.
