Approval and Promulgation of Air Quality Implementation Plans; Alaska

EPA approves a State Implementation Plan (SIP) revision submitted by the State of Alaska implementing an oxygenated gasoline program in the Municipality of Anchorage. This SIP revision was submitted to satisfy the requirement of section 211(m) of the Clean Air Act, as amended (the ``Act''), which requires all carbon monoxide (CO) nonattainment areas with a design value of 9.5 parts per million (ppm) or greater based generally on 1988 and 1989 air quality monitoring data to implement an oxygenated gasoline program. In the proposed rules section of this Federal Register, EPA is proposing approval of and soliciting public comment on this requested SIP revision. If adverse comments are received on this direct final rule, EPA will withdraw this direct final rule and address the comments received in a subsequent final rule on the related proposed rule. No additional opportunity for public comment will be provided. Unless this direct final rule is withdrawn, EPA will conduct no further rulemaking on this requested SIP revision.
