Start Preamble


Environmental Protection Agency.


Proposed rule.


The Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP) for the State of Iowa. The purpose of these revisions is to update the Polk County Board of Health Rules and Regulations, Chapter V, Air Pollution. These proposed revisions reflect updates to the Iowa statewide rules previously approved by EPA and will ensure consistency between the applicable local agency rules and Federally-approved rules. On April 15, 2014, the state amended their request and notified EPA that it is withdrawing their requests to approve to adopt greenhouse gases definition and sections relating to greenhouse gas emissions. This withdrawal request is in recognition of the July 12, 2013, U.S. Court of Appeals for the District of Columbia decision which vacated the regulation known as the “biogenic deferral rule”. On October 31, 2014, the state requested that EPA withdraw their request to approve the definition of anaerobic lagoon.


Comments on this proposed action must be received in writing by February 11, 2015.


Submit your comments, identified by Docket ID No. EPA-R07-OAR-2014-0163 by mail to: Heather Hamilton, Environmental Protection Agency, Air Planning and Development Branch, 11201 Renner Boulevard, Lenexa, Kansas 66219.

In the final rules section of this 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 If EPA receives relevant adverse comments, the direct Start Printed Page 1482final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action.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 the 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 which is located in the rules section of this Federal Register.
