Section 250-RICR-120-05-35.5 - Definitions

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.

9. "Coating" means a protective, decorative, or functional material applied in a thin layer to a surface. Such materials include, but are not limited to, paints, topcoats, varnishes, sealers, stains, washcoats, basecoats, adhesives, inks, enamels, and temporary protective 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. § 60 Appendix A-7 Method 24, incorporated in § 35.4(A) of this Part.

11. "Compliant coating" means a finishing material, adhesive, or strippable booth coating that meets applicable emission limitations specified in §§ 35.7 and 35.8 of this Part.

12. "Contact adhesive" means an adhesive that is applied to two (2) substrates, dried, and mated under only enough pressure to result in good contact. The bond is immediate and sufficiently strong to hold pieces together without further clamping, pressure, 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 destroy or secure the pollutant for subsequent recovery. Control devices include, but are not limited to, incinerators, carbon adsorbers, and condensers.

16. "Control device efficiency" means the ratio of the amount of pollutant released by a control device to the amount of pollutant introduced to the control device, expressed as a fraction.

17. "Control system" means the combination of capture and control devices used to reduce emissions to the atmosphere.

18.
