ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 70

[EPA-R07-OAR-2014-0164; FRL 9910-68-Region 7]

Approval and Promulgation of Implementation Plans; State of Iowa; 
Ambient Air Quality Standards, and Controlling Pollution

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve revisions to the State Implementation Plan (SIP) for the state 
of Iowa. These revisions will amend the SIP to include revisions to 
Iowa air quality rules necessary to allow for implementation of revised 
National Ambient Air Quality Standards (NAAQS) for fine particulate 
matter (PM2.5), lead, and sulfur dioxide (SO2) as 
they apply to construction permit exemptions. The spray booth ``permit 
by rule'' proposed revision will add content limits for lead-containing 
spray materials. The updated Federal references for the revised NAAQS 
are also included in this revision.
    EPA is also proposing to approve revisions to the Iowa Title V 
Operating Permits Program to modify requirements for insignificant 
activities. The changes will correspond to the revisions to the 
construction permit exemptions amended with this SIP revision.

DATES: Comments on this proposed action must be received in writing by 
June 13, 2014.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R07-
OAR-2014-0164, by mail to Amy Algoe-Eakin, Environmental Protection 
Agency, Air Planning and Development Branch, 11201 Renner Boulevard, 
Lenexa, Kansas 66219. Comments may also be submitted electronically or 
through hand delivery/courier by following the detailed instructions in 
the ADDRESSES section of the direct final rule located in the rules 
section of this Federal Register.

FOR FURTHER INFORMATION CONTACT: Amy Algoe-Eakin, Environmental 
Protection Agency, Air Planning and Development Branch, 11201 Renner 
Boulevard, Lenexa, Kansas 66219 at 913-551-7942, or by email at algoe-eakin.amy@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 which is located in the rules 
section of this Federal Register.

    Dated: April 29, 2014.

Regional Administrator, Region 7.
