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, for example emissions resulting from overspray. 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. The CTAP Automobile Refinishing presentation [PDF] identifies both similarities and differences between the two (2) regulations as well as identifying key features of both.
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. More specifically staff members can provide confidential assistance by phone or an on-site visit. An on-site visit may be requested through completion of the CTAP Consultation Request Form.
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 web site where informational tools can be found. It includes a table with pertinent information to autobody shops for each of the six (6) states.
