[Federal Register: March 8, 2007 (Volume 72, Number 45)] [Proposed Rules] [Page 10453-10454] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr08mr07-39] ----------------------------------------------------------------------- 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. ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R07- OAR-2006-1015 by one of the following methods: 1. http://www.regulations.gov: Follow the on-line instructions for submitting comments. 2.

FOR FURTHER INFORMATION CONTACT: Heather Hamilton at (913) 551-7039, or by e-mail at Hamilton.heather@epa.gov. 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 If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action.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. John B. Askew, Regional Administrator, Region 7.
