HYDROFLUOROCARBONS — EMISSIONS REDUCTION

RCW 70A.60
in effect

RCW 70A.60.005 Finding — Intent.

(1) The legislature finds that hydrofluorocarbons are air pollutants that pose significant threats to our environment. Although hydrofluorocarbons currently represent a small proportion of the state's greenhouse gas emissions, emissions of hydrofluorocarbons have been rapidly increasing in the United States and worldwide, and they are hundreds to thousands of times more potent than carbon dioxide. In 2019, the legislature took a significant step towards reducing greenhouse gas emissions from hydrofluorocarbons by transitioning to the use of less damaging hydrofluorocarbons or suitable substitutes in certain new foam, aerosol, and refrigerant uses. However, significant sources of hydrofluorocarbon emissions in Washington remain unaddressed by the 2019 legislation, including legacy uses of hydrofluorocarbons as a refrigerant in infrastructure that was installed prior to the effective dates of the restrictions in the 2019 law, and from sources like stationary air conditioners and heat pumps that were not covered by the 2019 law. (2) Therefore, it is the intent of the legislature to reduce hydrofluorocarbon emissions, including by: (a) Authorizing the establishment of a maximum global warming potential threshold for hydrofluorocarbons used as a refrigerant; (b) Authorizing the regulation of hydrofluorocarbons in air conditioning and heat pumps; (c) Applying the same basic emission control requirements to hydrofluorocarbons that have long applied to ozone-depleting substances used as refrigerants; (d) Establishing a program to reduce leaks and encourage refrigerant recovery from large refrigeration and air conditioning systems; (e) Directing the state building code council to adopt codes that are consistent with the goal of reducing greenhouse gas emissions associated with hydrofluorocarbons; (f) Establishing a state procurement preference for recycled refrigerants; and (g) Allowing consideration of the global warming potential of refrigerants used in equipment incentivized under utility conservation programs. (3) Furthermore, it is the intent of the legislature that the ice rink used by Seattle's newest hockey franchise, the Seattle Kraken, should be as cold as possible, but also should be refrigerated using climate-friendly refrigerants, so that on opening night of the 2021-2022 National Hockey League season, as many fans as possible can simultaneously yell the Pacific Northwest's favorite new phrase: 'Release the Kraken!'

(1) The department shall establish a refrigerant management program designed to reduce emissions of refrigerants, including regulated substances and their substitutes, from activities or equipment responsible for significant volumes of such emissions. The program must include, at minimum, larger stationary refrigeration systems and larger commercial air conditioning systems. The department must adopt rules to implement and enforce the requirements of this section. The department may require compliance with refrigerant management program requirements beginning no earlier than January 1, 2024, and no earlier than the adjournment of the regular legislative session following the submission of a report to the appropriate committees of the legislature by the department estimating leakage of refrigerants from existing systems in Washington, and estimating a statewide rate of leakage from the categories of systems that are subject to the refrigerant management program rules adopted by the department under this section. (2)(a) The department shall exempt refrigeration and air conditioning equipment operations associated with de minimis emissions or with a de minimis charging capacity of less than 50 pounds in a single system from registration, reporting, and leak detection requirements established in this section. The department shall exempt from the requirements established in this section equipment that uses refrigerants with a global warming potential of less than 150 and that are not class I or class II substances. (b) The department may scale the requirements adopted under this section based on the size of the equipment, the facility containing the equipment, or the business operations of a person responsible for such emissions. The department may establish delayed effective dates of requirements applicable to persons and systems associated with lower emissions of refrigerants than other persons and systems regulated under this section. (3) Each year, the owner or operator of a stationary refrigeration system or air conditioning system that exceeds a de minimis charge capacity of 50 pounds must register with the department. The department must phase in system registration requirements under this subsection in order to prioritize systems with the largest charge capacity or greatest potential for refrigerant emissions. Registration with the department must, consistent with rules adopted by the department, include the submission of information about the refrigeration system, including equipment type, refrigerant charge capacity, and the type of refrigerant used. (4) Prior to the sale of a registered refrigeration or air conditioning system, the owners or operators of the system must provide leak rate documentation to the prospective purchaser. (5) The owner or operator of a registered stationary refrigeration system or air conditioning system must conduct periodic leak-detection inspections of the system. The department may require inspections to be conducted with relatively greater frequency for systems with larger volumes of refrigerants. The department may exempt systems that use refrigerants with low global warming potential or that have automatic leak-detection systems from the requirements of this subsection. (6) The owner or operator of a registered stationary refrigeration or air conditioning system must inspect for leaks each time significant amounts of refrigerant are added to the system.

(8) The department may adopt rules to establish: (a) Service practices for stationary appliances, including both stationary refrigeration systems and air conditioning systems. Service practices established by the department may include requiring technicians certified under United States environmental protection agency standards to service refrigerant systems, requiring reporting and recordkeeping that identifies the technicians that have serviced appliances, prohibiting practices likely to result in releases to the environment, requiring all practicable efforts to recover refrigerants from covered systems, and prohibiting the addition of refrigerants to systems known to have a leak; and (b) A process for wholesalers, distributors, reclaimers, and refrigeration and air conditioning equipment operators to apply to the department for an exemption from some or all of the requirements of this section. Exemptions may be granted by the department on the basis of economic hardship, natural disaster, or after considering a calculation of life-cycle greenhouse gas emissions associated with the granting of an exemption that will allow an identified leak to go unrepaired for a finite period of time. (9) The department may determine, assess, and collect annual fees from the owners or operators of refrigeration and air conditioning systems regulated under this section in an amount sufficient to cover the direct and indirect costs of administering and enforcing the provisions of this section.
