ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R10-OAR-2008-0166; FRL -      ]

Approval and Promulgation of Implementation Plans; Alaska; 

Interstate Transport of Pollution

			

AGENCY:  Environmental Protection Agency (EPA).

ACTION:  Proposed rule.

SUMMARY:  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, or interfere with efforts of another state
to protect visibility.  

DATES:  Comments must be received on or before [insert date 30 days from
the date of publication in the Federal Register].

SUPPLEMENTARY INFORMATION:   	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.
