On July 9, United States Environmental Protection Agency (EPA) Administrator Gina McCarthy signed the proposed rule for the EPA Significant New Alternatives Policy (SNAP) Change of Status Decisions (De-Listing). The change in SNAP status would prohibit the use of particular HFCs in specific applications on a time table laid out by the EPA. In all cases the change of status makes the HFCs in question unacceptable for use in a) new equipment and b) retrofit applications. The proposed rule does not affect service use of any HFC.
Attached is an information sheet that includes Q&A’s regarding the proposed rule covering key elements of the proposal. As you can see, it is much broader than refrigeration. Also attached for your reference is a statement DuPont issued to the media on behalf of DC&F President Thierry Vanlancker regarding the proposed rule.
The links to the full text of the proposed rule and a separate EPA prepared fact sheet are provided below. It is expected that the proposed rule will appear in the Federal Register in the next two to three weeks. There will be a 60-day comment period and a provision for a public hearing.
