Proposed Amended Rule 1115 – Motor Vehicle Assembly Line Coating Operations
Document Type
NOE - Notice of Exemption
Document Description
Amendments to Rule 1115 are proposed that will update the volatile organic compound (VOC) emission limits for coatings used in automotive assembly line processes and for other miscellaneous materials used at motor vehicle assembly coating operations to comply with the United States Environmental Protection Agency’s Reasonably Available Control Technology requirements and their recommended 2008 Control Techniques Guidelines for Automobile and Light-Duty Truck Assembly Coatings. Other amendments are proposed that will: 1) separate the previously combined purpose and applicability subdivision into two parts; 2) revise the applicability requirements to include automotive parts that are coated during the vehicle assembly process as well as during associated solvent cleaning operations and exclude activities that would be subject to Rule 1151 - Motor Vehicle and Mobile Equipment Non-Assembly Line Coating Operations; 3) add new and modify existing definitions of terms; 4) update recordkeeping requirements; 5) revise the methods of analysis to include an additional test method for determining VOC and solids content of coatings and to update the criteria for determining transfer efficiency; and 6) delete the exemptions for trunk coatings, interior coatings, sealers and deadeners, and accent and stripe coatings.

Notice of Exemption

Exempt Status
Type, Section or Code
Reasons for Exemption
South Coast AQMD, as Lead Agency, has reviewed the proposed project pursuant to: 1) CEQA Guidelines Section 15002(k) – General Concepts, the three-step process for deciding which document to prepare for a project subject to CEQA; and 2) CEQA Guidelines Section 15061 – Review for Exemption, procedures for determining if a project is exempt from CEQA. Operators of all nine facilities subject to Rule 1115 are currently using coatings that comply with the proposed VOC emission limits and are applying these coatings using equivalent high-volume, low-pressure or other more transfer-efficient application method such that no physical modifications are expected to occur as a result of the proposed project. Thus, it can be seen with certainty that implementing the proposed project would not cause a significant adverse effect on the environment. Therefore, the proposed project is exempt from CEQA pursuant to CEQA Guidelines Section 15061(b)(3) – Common Sense Exemption.
