EPA: Review of Standards of Performance for Automobile and Light Duty Truck Surface Coating Operations
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 determined 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 volatile organic compound (VOC) emission limits for prime coat, guide coat, and topcoat operations for affected facilities that commence construction, modification, or reconstruction after May 18, 2022. In addition, in the new NSPS subpart, the EPA is finalizing 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 efficiency 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 amendments 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 NSPS subpart MM, applicable to sources that commence construction, reconstruction, or modification after October 5, 1979, and on or before May 18, 2022.
DATES: This final rule is effective on May 9, 2023, published in the Federal Register May 9, 2023, page 29978.

§60.390 Applicability and designation of affected facility.
* * * * *
(c) The provisions of this subpart apply to any affected facility identified in paragraph (a) of this section that begins construction, reconstruction, or modification after October 5, 1979.
§60.391 Definitions.
(a) * * *
Flash-off area means the structure on automobile and light-duty truck assembly lines between the coating application system (dip tank or spray booth) and the bake oven.
* * * *
§60.392 Standards for volatile organic compounds.
On and after the date on which the initial performance test required by §60.8 is completed, no owner or operator subject to the provisions of this subpart shall discharge or cause the discharge into the atmosphere from any affected facility VOC emissions in excess of:
§60.393 Performance test and compliance provisions.
* * * * *
(c) * * *
(2) * * *
(ii) * * *
(A) Determine the fraction of total VOC which is emitted by an affected facility that enters the control device by using the following equation where “n” is the total number of stacks entering the control device and “p” is the total number of stacks not connected to the control device:
If the owner can justify to the Administrator's satisfaction that another method will give comparable results, the Administrator will approve its use on a case-by-case basis.
(1) In subsequent months, the owner or operator shall use the most recently determined capture fraction for the performance test.
* * * * *
§60.395 Reporting and recordkeeping requirements.
(a) * * *
(2) Where compliance is achieved through the use of incineration, the owner or operator shall include the following additional data in the control device initial performance test requried by §60.8(a) or subsequent performance tests at which destruction efficiency is determined: the combustion temperature (or the gas temperature upstream and downstream of the catalyst bed), the total mass of VOC per volume of applied coating solids before and after the incinerator, capture efficiency, the destruction efficiency of the incinerator used to attain compliance with the applicable emission limit specified in §60.392 and a description of the method used to establish the fraction of VOC captured and sent to the control device.
(b) Following the initial performance test, the owner or operator of an affected facility shall identify, record, and submit a written report to the Administrator every calendar quarter of each instance in which the volume-weighted average of the total mass of VOC's emitted to the atmosphere per volume of applied coating solids (N) is greater than the limit specified under §60.392. If no such instances have occurred during a particular quarter, a report stating this shall be submitted to the Administrator semiannually. Where compliance is achieved through the use of a capture system and control device, the volume-weighted average after the control device should be reported.
(c) Where compliance with §60.392 is achieved through the use of incineration, the owner or operator shall continuously record the incinerator combustion temperature during coating operations for thermal incineration or the gas temperature upstream and downstream of the incinerator catalyst bed during coating operations for catalytic incineration. The owner or operator shall submit a written report at the frequency specified in §60.7(c) and as defined below.
