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 proposes to list certain substances in the refrigeration and air conditioning sector and the foam blowing sector. For the retail food refrigeration— medium-temperature stand-alone units (new) end-use, EPA is proposing to list substitutes as acceptable subject to narrowed use limits. For the residential and light commercial air conditioning and heat pumps (new) end-use, EPA is proposing to list substitutes as acceptable subject to use conditions. For the foam blowing sector, extruded polystyrene: Boardstock and billet end-use, EPA is proposing to list substitutes as acceptable. This action also proposes to remove 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.
