WHEREAS, in compliance with the Environmental Protection Agency’s 2021 issuance of a rule implementing an 85% economy-wide phasedown in HFC refrigerants by 2036, the International Code Council recently approved six code changes to the 2024 International Mechanical Code; and,
WHEREAS, these changes permit the use of A2L refrigerants consistent with industry standards and will facilitate compliance with EPA refrigerant regulations; and,
WHEREAS, the Codes Department has adopted the 2018 International Mechanical Code, as amended in 16.16.260, and the 2018 International Mechanical Code does not allow for A2L refrigerant to be considered a code compliant refrigerant, while the 2024 International Mechanical Code does; and,

NOW, THEREFORE, BE IT ENACTED BY THE COUNCIL OF THE METROPOLITAN GOVERNMENT OF NASHVILLE AND DAVIDSON COUNTY:

The 2018 International Mechanical Code is hereby amended by deleting Chapter 11 Refrigeration in its entirety, and replacing it in lieu thereof with Chapter 11 Refrigeration of the 2024 International Mechanical Code.
Section 2. This ordinance shall take effect upon passage, the welfare of The Metropolitan Government of Nashville and Davidson County requiring it.
