Adopted under notice filed as WSR 20-13-089 on June 16, 2020.

Changes Other than Editing from Proposed to Adopted Version: See the "concise explanatory statement" for more details.

Throughout Rule: We updated references to ecology RCW that were recodified to implement HB [SHB] 2246, which reorganized environmental health laws without making any substantive or policy changes.

WAC 173-443-030 Definitions and acronyms: We revised the following definitions in the foam end-use category to more closely align the definitions with industry terminology:

"Flexible polyurethane" means a nonrigid syntheticpolyurethane foam including, but not limited to, that used in furniture, bedding, and chair cushionscontaining polymers of urethane radicals including, but not limited to, that used in furniture, bedding, chair cushions, and shoe soles.

"Foam blowing agent" means a product or substance that functions as a source of gas to generate bubbles or cells in the mixture during the formation of foamused to produce the product with a cellular structure formed via a foaming process in a variety of materials that undergo hardening or phase transition.

"Foam system" means a multipart liquid materialproduct that expands when mixed to form a foamsolid or flexible substance in which thin films of material separate pockets of gas.

"Integral skin polyurethane" means a synthetic self-skinning polyurethane foam containing polymers of urethane radicals including, but not limited to, that used in shoe soles and car steering wheels and dashboards.

"Rigid polyurethane appliance foam" means polyurethane insulation foam in domestic appliances used for insulation.

"Rigid polyurethane commercial refrigeration and sandwich panels" means polyurethane foam used to provide insulation for use in walls and doors, including that used for commercial refrigeration equipment, and used in doors, including garage doors.

"Rigid polyurethane high-pressure two-component spray foam" means a liquid polyurethanea foam systemproduct that is pressurized 800-1600 psi during manufacture; sold in pressurized containers as two parts (i.e., A-side and B-side) in nonpressurized containers; and is field or factoryblown and applied in situ using high-pressure proportioning pumps at 800 - 1600 psito propel the foam components, and an application gun to mix and dispense the chemical componentsmay use liquid blowing agents without an additional propellant.

"Rigid polyurethane low-pressure two-component spray foam" means a foam productliquid polyurethane foam systemthat is pressurized to less than 250 psi during manufacture; sold in pressurized containers as two parts (i.e., A-side and B-side) in containers that are pressurized to less than 250 psi during manufacture of the system for application without pumps; and are typically applied in situ relying upon a liquid blowing agent and/or gaseous foam blowing agent that also serves as a propellant so pumps typically are not needed.

"Rigid polyurethane marine flotation foam" means buoyancy or flotation polyurethane foam used in boat and ship manufacturing for both structural and flotation purposes.

"Rigid polyurethane one-component foam sealants" means a polyurethane foam generally packaged in aerosol cans that is applied in situ using a gaseous foam-blowing agent that is also the propellant for the aerosol formulation.

"Rigid polyurethane slabstock and other" means a rigid closed-cell polyurethane foam containing polymers of urethane radicals formed into slabstock insulation for panels and fabricated shapes for pipes and vessels.

We added a definition for the term "stationary" to address ambiguity in the definition of "refrigeration equipment."

"Stationary" means the system is (1) installed in a building, structure, or facility; or (2) attached to a foundation, or if not attached, will reside at the same location for more than twelve consecutive months; or (3) located intermittently at the same facility for at least two consecutive years and operates at that facility a total of at least 90 days each year.

We added a definition of "sufficient disclosure" to address ambiguity in the option of using another jurisdiction's label for refrigeration and foam end-uses.

"Sufficient disclosure" means providing the name of the substitute.

WAC 173-443-060 Prohibitions: Subsection (2): We added additional distribution methods in the sell-through provision to align with similar provisions in the HFC law and United States Climate Alliance model rule.

Products and equipment manufactured prior to the applicable effective date of a prohibition in WAC 173-443-040 may be sold, leased, rented, imported, exported, distributed, installed, orused, or otherwise introduced into Washington commerce after the date of prohibition.

Subsection (2)(c): We expanded the sell-through provision from "spray foam systems" to "polyurethane foam systems."

PolyurethaneSpray foam systems manufactured (blended) before an applicable prohibition date and not yet applied on site may be used after the prohibition date.

WAC 173-443-070 Product labeling and disclosure requirements: Throughout section: We removed the qualifier "HFC" from all references to "HFC disclosure requirements of another jurisdiction."

Subsection (3)(a): We revised the order in which the two federal agencies appear.

For aerosol products regulated by the U.S. Consumer Product Safety Commission, the U.S. Food and Drug Administration excluding prescription drug products, the U.S. Consumer Product Safety Commission, or products that are not covered by (b) of this subsection.

Subsection (4) and (5): We added the option of using another jurisdiction's label and clarified when it must be combined with online disclosure in subsections (4)(a)(iii) and (iv), (4)(c)(iv) and (v), and (5)(a)(iv) and (v).

A label required by another jurisdiction with sufficient HFC disclosure requirements; and online disclosure;

A label required by another jurisdiction that does not disclose the substitute; and online disclosure; or

Subsection (6): We revised subsections (6)(a)(ii)(C) and (D) and (6)(b)(iv) and (v) so that online disclosure is only required with use of another jurisdiction's label if the other jurisdiction's label does not adequately disclose the substitute.

A label required by another jurisdiction with sufficient HFC disclosure requirements; and online disclosure;

A label required by another jurisdiction that does not disclose the substitute; and online disclosure; or

We revised terminology in subsection (6)(c) to align with revisions in subsection (2)(c).

For the foam blowing agent used in polyurethane foam systems, including spray foam systems:

We added two new options in subsection (6)(c)(iv) and (v) to allow use of another jurisdiction's label for polyurethane foam systems.

A label required by another jurisdiction with sufficient disclosure requirements;

A label required by another jurisdiction that does not disclose the substitute; and online disclosure; or

Subsection (7): We removed unnecessary language to improve consistency with other subsections.

Ecology must approve in advance the use of a symbol or code to comply with this section.

Subsection (9): We added clarification that online publication of a safety data sheet, owner's manual, or other product document qualifies as "online disclosure."

Online disclosure may occur through online publication of an owner's manual, safety data sheet, or other documentation that provides information about the product to the end-user of the product.

WAC 173-443-080 Manufacturer Notification:Subsection (1): We clarified that notification is only required for manufacturers using HFCs or other prohibited substitutes for an end-use listed in WAC 173-443-040.

A manufacturer of a product or equipment that contains, uses, or will use HFCs or other substitutes prohibited for an end-use listed in WAC 173-443-040 or a representative on behalf of the manufacturer, must report to ecology consistent with WAC 173-443-090 and 173-443-100.
