Collision Repair/Auto Refinishing Shops

Along with applicable waste and water regulations, Collision Repair and Auto Refinishing Shops may be subject to federal and state environmental regulations concerning air emissions. 40 CFR 63, Subpart HHHHHH (6H or the U.S. EPA Autobody Rule) regulates emissions of Cadmium, Chromium, Lead, Manganese, Nickel, and Methylene Chloride resulting from overspray during surface coating operations.

The Indiana state rule, 326 IAC 8-10, regulates emissions of volatile organic compounds (VOCs). For example, evaporation of solvent used as an ingredient in a base coat formula would be regulated by 326 IAC 8-10. The CTAP Automobile Refinishing presentation [PDF] identifies both similarities and differences between the two (2) regulations (state and federal), as well as identifying key features of both.

A presentation [PDF] on the specific aspects of 6H and some elements of 326 IAC 8-10, was made on December 6, 2016 to air inspectors. Compliance and Technical Assistance Program (CTAP) staff are available to assist Collision Repair and Auto Refinishing Shops with general or specific questions and concerns as well as to help them understand and comply with applicable environmental regulations.

Other Resources

Regarding 40 CFR 63, Subpart HHHHHH (6H or the U.S. EPA Autobody Rule), Indiana collaborated with five (5) other states (Illinois, Michigan, Minnesota, Ohio and Wisconsin) to develop informational tools to help an autobody shop comply with 6H. The results of this collaboration can be found within the Environmental Results Program (ERP) for Autobody Refinishing Shops Project [PDF].

The State of Wisconsin hosts the website where informational tools can be found..
