Protection of Stratospheric Ozone: Listing of Substitutes Under the Significant New Alternatives Policy Program
Pursuant to the U.S. Environmental Protection Agency's (EPA) Significant New Alternatives Policy program, this action lists certain substances in the refrigeration and air conditioning sector. For the retail food refrigerationmedium-temperature stand-alone units (new) end-use, EPA is listing three substitutes as acceptable subject to narrowed use limits. For the residential and light commercial air conditioning and heat pumps (new) end-use, EPA is listing six substitutes as acceptable subject to use conditions. Through this action, EPA is incorporating by reference the 2019 Underwriters Laboratories (UL) Standard 60335-2-40, 3rd Edition, which establishes requirements for the evaluation of electrical air conditioners, heat pumps, and dehumidifiers, and safe use of flammable refrigerants. This action also removes an acceptable subject to use conditions listing for the fire suppression sector because EPA more recently listed the substitute as acceptable with no use restrictions.
Significant New Use Rules on Certain Chemical Substances (19-1.F)
EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances which were the subject of premanufacture notices (PMNs) and a microorganism that was the subject of a Microbial Commercial Activity Notice (MCAN). This action requires persons to notify EPA at least 90 days before commencing manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use by this rule. This action further requires that persons not commence manufacture or processing for the significant new use until they have submitted a Significant New Use Notice (SNUN), and EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken any risk management actions as are required as a result of that determination.
