Flat Wood Panel Coatings

Change in Proposed Rule

DAR File No.: 38682
Filed: 10/07/2014 10:02:03 AM

RULE ANALYSIS

Purpose of the rule or reason for the change:

The EPA has indicated its intention to approve the area source coatings rules for the PM2.5 State Implementation Plan as reasonable available control technology (RACT), but not until: 1) they are amended to clarify that the amount of control removal specified in each rule is based on the entire system, and 2) the inspection and recordkeeping requirements for these systems are expanded. These changes were proposed to this and 13 other air quality area source rules, and a 30-day public comment period was held. During the public comment period, several inquiries were made regarding why the rules do not permit the use of exempt solvents for cleaning. The definition of "volatile organic compound (VOC)" found in Section R307-101-2 incorporates the definition of VOC found in 40 CFR 51.100(s)(1). This definition does permit the use of exempt compounds for cleaning; however, this allowance is not explicitly stated in this or the other proposed area source rules. The change to the proposed rule is to specify that exempt compounds are not VOC by definition.

Summary of the rule or change:

The change clarifies that exempt compounds are not VOC by definition. (DAR NOTE: The original proposed amendment upon which this change in proposed rule (CPR) was based was published in the August 1, 2014, issue of the Utah State Bulletin, on page 30. Underlining in the rule below indicates text that has been added since the publication of the proposed rule mentioned above; strike-out indicates text that has been deleted. You must view the CPR and the proposed amendment together to understand all of the changes that will be enforceable should the agency make this rule effective.)

State statutory or constitutional authorization for this rule:

• Subsection 19-2-104(1)(a)

Anticipated cost or savings to:

R307. Environmental Quality, Air Quality.

R307-349. Flat Wood Panel Coatings.

R307-349-1. Purpose.

The purpose of R307-349 is to limit volatile organic compound (VOC) emissions from flat wood paneling coating sources.

 

R307-349-2. Applicability.

R307-349 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties that have the potential to emit 2.7 tons per year or more of VOC, including related cleaning activities.

 

R307-349-3. Definitions.

The following additional definitions apply to R307-349:

"Coating" means a protective, decorative, or functional material applied in a thin layer to a surface. Such materials may include paints, topcoats, varnishes, sealers, stains, washcoats, basecoats, inks, and temporary protective coatings.

"Finishing material" means a coating used in the flat wood panel industry, including basecoats, stains, washcoats, sealers, and topcoats.

"Flat wood paneling" means wood paneling products that are any decorative interior, exterior or tileboard (class I hardboard) panel to which a protective, decorative, or functional material or layer has been applied.

"Sealer" means a finishing material used to seal the pores of a wood substrate before additional coats of finishing material are applied. A washcoat used to optimize aesthetics is not a sealer.

"Strippable booth coating" means a coating that is applied to a booth wall to provide a protective film to receive overspray during finishing and that is subsequently peeled and disposed. Strippable booth coatings are intended to reduce or eliminate the need to use organic solvents to clean booth walls.

"Tileboard" means a premium interior wall paneling product made of hardboard that meets the specifications for Class I given by the standard ANSI/AHA A135.4-1995.

 

R307-349-4. VOC Content Limit.

(1) Each owner or operator shall not apply coatings with a VOC content in excess of 2.1 pounds of VOC per gallon, excluding water and exempt solvents (compounds not classified as VOC). The equivalent emission limit shall be 2.9 pounds VOCs per gallon solids coating; or

(2) Each owner or operator shall use an add-on control device as specified in R307-349-6.

 

R307-349-5. Work Practice and Recordkeeping.

(1) The owner or operator shall:

(a) Store all VOC-containing coatings, thinners, and cleaning materials in closed containers;

(b) Minimize spills of VOC-containing coatings, thinners, and cleaning materials;

(c) Clean up spills immediately;

(d) Convey any coatings, thinners, and cleaning materials in closed containers or pipes;

(e) Close mixing vessels that contain VOC coatings and other materials except when specifically in use; and

(f) Minimize usage of solvents during cleaning of storage, mixing, and conveying of equipment.

(2) No person shall apply any coating unless the coating application method achieves a demonstrated 65% transfer efficiency.

The following applications achieve a minimum of 65% transfer efficiency and shall be operated in accordance with the manufacturers specifications:

(a) Paint brush;

(b) Flow coat;

(c) Roll coat;

(d) Dip coat;

(e) Detailing or touch-up guns;

(e) High-volume, low-pressure (HVLP) spray;

(f) Hand application methods; or

(g) Other application method capable of achieving at least 65% transfer efficiency, as certified by the manufacturer.

(3) No person shall use organic solvents for cleaning operations that exceed a VOC content (excluding water and solvents exempt from the definition of volatile organic compounds found in R307-101-2) of 0.21 pounds per gallon and a strippable booth coating with a VOC content in excess of 3.8 pounds per gallon, excluding water and exempt solvents (compounds that are not defined as VOC).

(4) All sources subject to R307-349 shall maintain records demonstrating compliance with R307-349-4 and R307-349-5.
