South Coast AQMD is conducting a survey for manufacturers who sell automotive refinishing coatings and products for use within the South Coast AQMD that are subject to Rule 1151 - Motor Vehicle and Mobile Equipment Non-Assembly Line Coating Operations. The intent of the survey is to assist the South Coast AQMD staff to understand the extent to which exempt solvents are used to formulate compliant products. The main exempt compounds of interest for this survey are para-chlorobenzotrifluoride (pCBtF), also known as Oxsol, and tertiary-Butyl Acetate (t-BAc). The survey results will be used to help guide South Coast AQMD staff in evaluating VOC content limits and proposing t-BAc and pCBtF prohibition timelines. This survey was sent to coatings manufactures on December 22, 2023, no action is required for other stakeholders.
