Collision repair and auto body shops typically fall under the NAICS 811121 and SIC 7532. Most of these businesses generate air emissions and hazardous waste from painting processes regulated by the state or EPA. This page focuses on the coating-related air quality regulations that impact the sector.
In recent years, collision repair and autobody shops have had to come into compliance with a National Emission Standard for Hazardous Air Pollutants known as the NESHAP HHHHHH or 6H rule, which applies to paint stripping and miscellaneous surface-coating operations including collision repair. In fact, collision repair shops are considered under the rule unless they petition for an exemption (see sample form below) from it. The resources below, which include a link to a new 6H regulatory navigation tool, provide more detail on this rule as it applies to the collision repair industry.
