EPA issues rule on refrigerant

摘要

WASHINGTON— The U.S. Environmental Protection Agency (EPA) has issued a Significant New Use Rule (SNUR) covering HFL-1234yf, a new refrigerant designed for motor vehicle air conditioning units. According to the SNUR. HFO-1234yf is approved for use as a refrigerant only in new motor vehicles, and any company planning to use it for other purposes must first obtain the EPA's approval. Anyone who intends to manufacture, import or process the substance must notify the agency at least 90 days before beginning, so the EPA may review and, if necessary, prohibit or limit the proposed activity.
