Collision Repair/Auto Refinishing Shops

Collision Repair and Auto Refinishing generally means the repair and restoration of an automobile, which usually includes the application of paint to the vehicle. 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 from the paint application processes. Paints can include pigment or color, which may be made of heavy metals that can be hazardous to human health and the environment. Additionally, paints often contain regulated volatile organic compounds (VOCs). Even an aqueous (water) based paint may contain a certain amount of a regulated VOCs. IDEMs Office of Air Quality (OAQ) provides Automobile Refinishing Rule Information and Guidance to sources needing to understand or obtain permits for these facilities.

Federal Regulation

The U.S. EPA Autobody Rule, 40 CFR 63, Subpart HHHHHH (6H) regulates emissions of hazardous air pollutants (HAPs), specifically, Cadmium, Chromium, Lead, Manganese, Nickel, and Methylene Chloride resulting from overspray during surface coating operations. Owners or operators may petition U.S. EPA for exemption from this regulation if none of the coatings used at their facility contain any of the target HAPs listed above. The petition must be submitted to and approved by the U.S. EPA.

State of Indiana Regulation

The Indiana state rule for Automobile Refinishing, 326 IAC 8-10, regulates VOC emissions from refinishing processes by limiting VOC content of coatings and requiring work practice standards to limit evaporation of volatile compounds. Following the required work practices of this rule is not only beneficial to the environment, but often saves businesses money by increasing the longevity of solvents or the transfer efficiency of paints.

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. Additionally, a presentation [PDF] on the specific aspects of 6H and some elements of 326 IAC 8-10, was created to assist air inspectors when visiting auto body refinishing or collision repair facilities. 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 autobody shops 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.
