**Approval and Promulgation of Implementation Plans; Georgia: State**  **Implementation Plan Revision**

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to approve revisions to the Georgia State Implementation Plan (SIP), submitted by the Georgia Environmental Protection Division on September 26, 2006, with a clarifying revision submitted on November 6, 2006. The proposed revisions include multiple modifications to Georgia’s Air Quality Rules found at Chapter 391–3–1. These revisions are part of Georgia’s strategy to meet the national ambient air quality standards. EPA is proposing to approve Georgia’s SIP revisions pursuant to section 110 of the Clean Air Act.

EPA is not acting on revisions to rules 391–3–1–.01(qqqq), 391–3–1–.02(2)(zz), 391–3–1–.02(2)(mmm), 391–3–1– .02(6)(a), 391–3–1–.03(6)(g), and 391–3– 1–.03(6)(i) at this time. EPA is also not acting on revisions to rule 391–3–1– 02(2)(ooo), as Georgia has submitted a revised version of the rule. Additionally, we are not acting on several revisions to the September 26, 2006, SIP submittal, that are not part of the federally approved SIP.

**SUPPLEMENTARY INFORMATION :**  In the Final Rules Section of this Federal Register, EPA is approving the State’s SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this rule, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this document. Any parties interested in commenting on this document should do so at this time.

**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.
