Start Preamble

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.

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.
