Protection of Stratospheric Ozone: New Substitute in the Motor 
Vehicle Air Conditioning Sector Under the Significant New Alternatives 
Policy (SNAP) Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; reopening of public comment period.

-----------------------------------------------------------------------

SUMMARY: EPA issued a proposed rule in the Federal Register of October 
19, 2009, proposing to find HFO-1234yf acceptable, subject to use 
conditions as a substitute for CFC-12 in motor vehicle air 
conditioning. The proposed substitute is a non-ozone-depleting 
substance and consequently does not contribute to stratospheric ozone 
depletion. In response to requests from several stakeholders and to 
allow comments on new supporting materials, this action reopens the 
public comment period through February 24, 2010.

DATES: The comment period for the proposed rule published October 19, 
2009 (74 FR 53445), is reopened. Comments, identified by docket 
identification (ID) number EPA-HQ-OAR-2008-0664, must be received on or 
before February 24, 2010.

automatically captured and included as part of the comment that is

disk or CD-ROM you submit. If EPA cannot read your comment due to 
technical difficulties and cannot contact you for clarification, EPA 
may not be able to consider your comment. Electronic files should avoid 
the use of special characters, any form of encryption, and be free of 
any defects or viruses.
    Docket: All documents in the docket are listed in the http://www.regulations.gov index. Although listed in the index, some

SUPPLEMENTARY INFORMATION: 

Background

    The statutory and regulatory background is described in detail in 
the Federal Register proposed rule of October 19, 2009 (74 FR 53445). 
In that document, EPA proposed to find HFO-1234yf acceptable as an 
alternative refrigerant for motor vehicle air conditioning, subject to 
use conditions. The refrigerant discussed in the proposed action, for 
which the comment period is reopened, is a non-ozone-depleting 
substance.

This Action

    EPA has received a request for an extension to the comment deadline 
for this proposed rule.
    This action reopens the comment period. The Agency will consider 
additional comments we receive through February 24, 2010 in response to 
this action. Note that additional information is available in the 
public docket, EPA-HQ-OAR-2008-0664, since publication of the October 
19, 2009 proposed rule and a subsequent notice reopening the public 
comment period (December 28, 2009; 74 FR 68558). EPA will also consider 
comments received by February 24, 2010 in response to the previous 
Federal Register publication [EPA-OAR-2008-0664] before issuing a final 
regulatory determination for HFO-1234yf. We intend to issue a 
regulatory determination as expeditiously as possible following 
consideration of the comments and information we receive.

    Dated: February 3, 2010.
Gina McCarthy,
Assistant Administrator, Office of Air and Radiation.
