On June 20, 2017, the Governing Board of the Antelope Valley Air Quality Management District (AVAQMD) agreed to adopt Rule 1151.1 - Motor Vehicle Assembly Coating Operations. The purpose of this adoption is to provide clarity and reflect current federal Reasonably Available Control Technology (RACT) for sources subject to Control Techniques Guidelines for Automobile  and Light-Duty Truck Assembly Coatings (EPA-453/R-08-006, September 2008) (CTG). Rule 1151.1 is necessary to satisfy 42 United States Code 7511a Federal Clean Air Act 182, which requires ozone non-attainment areas to implement RACT for those sources that are subject to CTG and for major sources of ozone precursors.

Rule 1151.1 applies to all motor vehicle assembly coating operations that apply VOC-containing coatings to new motor vehicles, new light-duty trucks, new heavier vehicles and other parts that are coated during the vehicle assembly process. Associated solvent cleaning activities are also included.  Exemptions to Rule 1151.1, which include the following:
