Description:  Review of Standards of Performance for Automobile and Light Duty Truck Surface 
Coating Operations  
AGENCY: Environmental Protection Agency (EPA)  
ACTION: Final rule  
SUMMARY: The Environmental Protection Agency (EPA) is finalizing amendments to the new source 
performance standards for Automobile and Light Duty Truck Surface Coating Operations  pursuant 
to the review required by the Clean Air Act . The EPA determi ned that revisions to the NSPS were 
needed to reflect the degree of emission limitation achievable through the application of the best

  system of emission reduction (BSER). The EPA is therefore finalizing, as proposed, in a new NSPS 
subpart MMa, revised vol atile organic compound (VOC) emission limits for prime coat, guide coat, 
and topcoat operations for affected facilities that commence construction, modification, or 
reconstruction after 18 May 2022. In addition, in the new NSPS subpart, the EPA is finalizi ng the 
proposed amendments: the addition of work practices to minimize VOC emissions; revision of the 
plastic parts provision; updates to the capture and control devices and the associated testing and 
monitoring requirements; revision of the transfer effic iency provisions; new test methods and 
alternative test methods; revision of the recordkeeping and reporting requirements, including the 
addition of electronic reporting; removing exemptions for periods of startup, shutdown, and 
malfunction; and other amen dments to harmonize the new NSPS subpart and Automobile and Light 
Duty Truck Surface Coating National Emission Standards for Hazardous Air Pollutants (NESHAP) 
requirements. The EPA is also finalizing the proposed electronic reporting requirements in the NS PS 
subpart MM, applicable to sources that commence construction, reconstruction, or modification after 
5 October 1979, and on or before 18 May 2022.  
DATES: This final rule is effective on 9 May 2023. The incorporation by reference of certain 
publications l isted in the rule is approved by the Director of the Federal Register as of 9 May 2023.
