ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R07-OAR-2006-1015; FRL-8284-9]


Approval and Promulgation of Implementation Plans; Iowa; 
Interstate Transport of Pollution

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing a revision to the Iowa State Implementation 
Plan (SIP) for the purpose of approving the Iowa Department of Natural 
Resources' (IDNR) actions to address the ``good neighbor'' provisions 
of the Clean Air Act Section 110(a)(2)(D)(i). These provisions require 
each state to submit a SIP that prohibits emissions that adversely 
affect another state's air quality through interstate transport. IDNR 
has adequately addressed the four distinct elements related to the 
impact of interstate transport of air pollutants. These include 
prohibiting significant contribution to downwind nonattainment of the 
National Ambient Air Quality Standards (NAAQS), interference with 
maintenance of the NAAQS, prevention of significant deterioration of 
air quality, and significant deterioration of visibility. The 
requirements for public notification were also met by IDNR.

DATES: Comments on this proposed action must be received in writing by 
April 9, 2007.

SUPPLEMENTARY INFORMATION: In the final rules section of the 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 revision amendment and anticipates no relevant adverse 
comments to this action. A detailed rationale for the approval is set 
forth in the direct final rule. If no relevant adverse comments are 
received in response to this action, no further activity is 
contemplated in relation to this action. If EPA receives relevant 
adverse comments, the direct final rule will be withdrawn and all 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 action. 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 EPA receives 
adverse comment on part of this rule and if that part can be severed 
from the remainder of the rule, EPA may adopt as final those parts of 
the rule that are not the subject of an adverse comment. For additional 
information, see the direct final rule that is located in the rules 
section of this Federal Register.

    Dated: February 27, 2007.

Regional Administrator, Region 7.
