Current through June 14, 2024
A. Unless otherwise expressly defined in this
				  section, the terms used in this regulation shall be defined by reference to
				  Part 0 of this Subchapter (General Definitions). As used in this regulation,
				  the following terms shall, where the context permits, be construed as follows:
1. "Adhesive" means a chemical substance that
				  is applied for the purpose of bonding two (2) surfaces together other than by
				  mechanical means.
2. "Alternative
				  method" means a method of sampling and analyzing for an air pollutant that is
				  not a reference or equivalent EPA sampling method but that has been
				  demonstrated to the EPA's satisfaction to, in specific cases, produce results
				  adequate for a determination of compliance.
3. "As applied" means the VOC, VHAP and
				  solids content of the coating material as it is used for coating the substrate,
				  including the contribution of thinners.
4. "Basecoat" means a coat of colored
				  material, usually opaque, that is applied before graining inks, glazing coats,
				  or other opaque finishing materials and is usually top coated for
				  protection.
5. "Capture device"
				  means a hood, enclosed room, floor sweep, or other means of collecting solvent
				  emissions or other pollutants into a duct so that pollutants can be directed to
				  a pollution control device such as an incinerator or a carbon
				  adsorber.
6. "Capture efficiency"
				  means the fraction of all organic vapors generated by a process that are
				  directed to a control device.
7.
				  "Certified product data sheet" or "CPDS" means documentation furnished by a
				  coating supplier or an outside laboratory that provides the VHAP content, VOC
				  content, solids content, and density of a finishing material, strippable booth
				  coating, adhesive, or solvent, measured using
				  40 C.F.R.§
												60, Appendix A-7 Method 24 and
				  40 C.F.R. §
												63 Method 311, or an equivalent or
				  alternative method (or formulation data if the coating meets the criteria
				  specified in §35.12.1(B) of this Part. The purpose of the CPDS is to
				  assist the facility in demonstrating compliance with the emission limitations
				  presented in §§
											35.7,
				  35.8, and
				  35.9 of this Part.
				  Therefore, the VOC and VHAP content should represent the maximum VOC and VHAP
				  emission potential of the finishing material, strippable booth coating, or
				  solvent.
8. "Cleaning operations"
				  means operations in which organic solvent is used to remove coating materials
				  from equipment used in wood products manufacturing operations.

				  coatings.
10. "Coating solids" or
				  "Solids" means the part of a coating that remains after the coating is dried or
				  cured; solids content is determined using data from
				  40 C.F.R. §

											35.4(A) of
				  this Part.
11. "Compliant coating"

				  or airing.
13. "Continuous coater"
				  means a finishing system that continuously applies finishing materials onto
				  wood parts moving along a conveyor system. Finishing materials that are not
				  transferred to the part are recycled to the finishing material reservoir.
				  Several types of application methods can be used with a continuous coater
				  including spraying, curtain coating, roll coating, dip coating, and flow
				  coating.
14. "Continuous
				  compliance" means that the facility is meeting the applicable emission
				  limitations and other applicable requirements of this regulation at all times
				  and is fulfilling all monitoring and recordkeeping provisions of the regulation
				  in order to demonstrate compliance.
15. "Control device" means any equipment that
				  reduces the quantity of a pollutant that is emitted to the air. The device may
