2023 Senate Bill 324
Senate Substitute
Amendment 1
2023 SENATE BILL 324
2023 Senate Bill 324 prohibits any state agency or local governmental unit from prohibiting or
otherwise limiting the use of certain refrigerants. Specifically, if the U.S. Environmental Protection
Agency (EPA) has designated a refrigerant as an acceptable alternative to ozone-depleting refrigerants,
a state agency or local governmental unit may not prohibit or otherwise limit the use of the refrigerant.
The equipment containing the refrigerant must be listed and installed in accordance with safety
standards and use conditions imposed pursuant to the EPA designation as an acceptable alternative.
SENATE SUBSTITUTE AMENDMENT 1
Senate Substitute Amendment 1 maintains the general prohibition, but applies it more specifically to
building codes, rather than general use, as established or enforced by the Department of Safety and
Professional Services (DSPS), or a county, city, village, or town. Under the substitute amendment, DSPS
and a county, city, village, or town may not enact or enforce a building code that prohibits or otherwise
limits the use of a refrigerant that the EPA has designated as an acceptable alternative. As under the
bill, the equipment containing the refrigerant must be listed and installed in accordance with safety
standards and use conditions imposed pursuant to the EPA designation as an acceptable alternative.
