Environmental Protection Agency (EPA).


Proposed rule.


EPA is proposing to approve the action of the Alaska Department of Environmental Conservation (ADEC) to address the provisions of Clean Air Act section 110(a)(2)(D)(i) for the 8-hour ozone and PM2.5 National Ambient Air Quality Standards (NAAQS). These provisions require each state to submit a State Implementation Plan (SIP) revision that prohibits emissions that adversely affect another state's air quality through interstate transport. EPA is proposing to approve ADEC's SIP revision because it adequately addresses the four distinct elements related to the impact of interstate transport of air pollutants for the state of Alaska. These include prohibiting emissions that contribute significantly to nonattainment of the NAAQS in another state, interfere with maintenance of the NAAQS by another state, interfere with plans in another state to prevent significant deterioration of air quality, Start Printed Page 60997or interfere with efforts of another state to protect visibility.

For further information, please see the direct final action, of the same title, which is located in the Rules section of this Federal Register. EPA is approving the State's SIP revision as a direct final rule without prior proposal because EPA views this as a noncontroversial SIP revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If EPA receives no adverse comments, EPA will not take further action on this proposed rule.

If EPA receives adverse comments, EPA will withdraw the direct final rule and it will not take effect. EPA will address all public comments in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time. Please note that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.
