Adhesive means any chemical substance that is applied for the purpose of bonding two surfaces together. Capture device means a hood, enclosure, room, floor sweep, or other means of containing or collecting emissions and directing those emissions into an add on air pollution control device. Capture efficiency or capture system efficiency means the portion (expressed as a percentage) of the pollutants from an emission source that is delivered to an add on control device. Capture system means one or more capture devices intended to collect emissions generated by a coating operation in the use of coatings or cleaning materials, both at the point of application and at subsequent points where emissions from the coatings or cleaning materials occur, such as flashoff, drying, or curing. As used in this subpart, multiple capture devices that collect emissions generated by a coating operation are considered a single capture system. Cleaning material means a solvent used to remove contaminants and other materials, such as dirt, grease, oil, and dried or wet coating (e. g., depainting), from a substrate before or after coating application or from equipment associated with a coating operation, such as spray booths, spray guns, racks, tanks, and hangers. Thus, it includes any cleaning material used on substrates or equipment or both. Coating means a material applied to a substrate for decorative, protective, or functional purposes. Such materials include, but are not limited to, paints, sealants, caulks, inks, adhesives, and maskants. Decorative, protective, or functional materials that consist only of protective oils for metal, acids, bases, or any combination of these substances are not considered coatings for the purposes of this subpart. Coating operation means equipment used to apply cleaning materials to a substrate to prepare it for coating application or to remove dried coating (surface preparation); to apply coating to a substrate (coating application) and to dry or cure the coating after application; or to clean coating operation equipment (equipment cleaning). A single coating operation may include any combination of these types of equipment, but always includes at least the point at which a coating or cleaning material is applied and all subsequent points in the affected source where organic HAP emissions from that coating or cleaning material occur. There may be multiple coating operations in an affected source. Coating application with hand held nonrefillable aerosol containers, touchup markers, or marking pens is not a coating operation for the purposes of this subpart. Coating solids means the nonvolatile portion of the coating that makes up the dry film. Continuous parameter monitoring system (CPMS) means the total equipment that may be required to meet the data acquisition and availability requirements of this subpart, used to sample, condition (if applicable), analyze, and provide a record of coating operation, or capture system, or add on control device parameters.

Subject
New Source Performance Standards (NSPS) Review for the "Surface Coating of Plastic Parts for Business Machines" Source Category
Stakeholder
FM Corp. (Ivonne Salinas); Affinity Consultants (Keith Gaydosh); Xerox (Danelle Giannini, Benjamin Sperr, Marcus Lathrop, Jean VanEpps); American Coatings Association (Heidi McAuliffe), Sherwin Williams (Steve Kerr).
EPA in attendance
Lisa Sutton, Keith Barnett, Elineth Torres
ERG in attendance
Bryan Lange

Presentation:
EPA's Lisa Sutton presented a 20 slide PowerPoint presentation that outlined the purpose of the meeting, regulatory schedule, and discussion topics. That presentation in attached to this PDF file.
EPA is soliciting information on how a new product line would be designed. Presumably owner operators would consider a concentration that of explosive and occupational exposure limit before it is designed and constructed. EPA will prove a separate file documenting the design parameters used to create a model plant used to estimate the cost of each regulatory options.
Stakeholder Insights and Questions:
1. FM Corp. had the following question about applicability:
      FM Corp. has a single customer whose coated items seem to be subject to Subpart TTT. Specifically, we mold and paint the parts that are shipped to a manufacture of 3D printers. The printer manufacturer assembles the parts.  Does that fit into the scope of this rule?
      Further, the 60.721 definition of business machine "such as" list include photographic equipment and a 3D printer is clearly not a photocopier. The 3D printer uses a liquid polymer base that is stacked to form an item.
EPA Response: This is not the forum for an applicability determination. If you submit a public comment on this proposed rule, then EPA will respond. EPA appreciates your situation given that the Standard Industrial Classification (SIC) codes are no longer used by the U.S. Department of Labor.

EPA is targeting June 1, 2022, for publication of the proposed rule. Typically, there is 45-day comment period. We would appreciate your comment on how the definition might need to change.
2.  FM Corp. will have to look at the regulatory option #1 which reduces the coating VOC limit from 1.5 kg of VOC per liter of coating solids applied to 0.95 (slide 16) to see if we can comply with that option.
EPA Response: Understand that the proposed revision would apply to facilities that are new, modified, or reconstructed after the date that the final rule is published (EPA is targeting June 1, 2022). A source that is currently subject to the NSPS will continue to be subject unless it adds a new product line, or the existing product line is modified or reconstructed.
3. The facility emission totals (slide 12) how were those calculated?
EPA Response: The emission totals are from recent operating permits. EPA acknowledges these limits (e.g., FM Corp.'s 95 tons of VOC per year) could be designed to avoid becoming a major Title V source. EPA also acknowledges that VOC surface coating content limits do not translate into an annual emission rate. If EPA misrepresented any facilities VOC limits, then let us know and EPA will consider revising the emission rate for the model plant.
4. Will there be a provision in the proposed rule will allows the regulated entity to demonstrate that add on-controls are cost prohibitive?
EPA Response: The EPA is considering a range of options. One option is coatings with a VOC content lower than they current rule. A second option is add-on controls. EPA will consider costs and environmental impacts to determine the best system of emission reduction (BSER). Facilities would have to meet that BSER emission limit. How a facility meets that BSER limit is up to them i.e., compliant coating. Helping EPA to accurately estimate cost helps EPA make well informed decisions. Further, it is better to make revision to costs before the rule proposal.
