[EPA-R07-OAR-2017-0267; FRL-9970-98-Region 7]


Approval of Implementation Plans; State of Iowa; Elements of the 
Infrastructure SIP Requirements for the 2010 Sulfur Dioxide National 
Ambient Air Quality Standard (NAAQS); Withdrawal

AGENCY: Environmental Protection Agency (EPA).

ACTION: Withdrawal of direct final rule.

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

SUMMARY: Due to an adverse comment, the Environmental Protection Agency 
(EPA) is withdrawing the direct final rule for Approval of 
Implementation Plans; State of Iowa; Elements of the Infrastructure SIP 
Requirements for the 2010 Sulfur Dioxide National Ambient Air Quality 
Standard (NAAQS) published in the Federal Register on September 29, 
2017. Infrastructure SIPs address the applicable requirements of Clean 
Air Act (CAA) section 110, which requires that each state adopt and 
submit a SIP for the implementation, maintenance, and enforcement of 
each new or revised NAAQS promulgated by the EPA. These SIPs are 
commonly referred to as ``infrastructure'' SIPs. The infrastructure 
requirements are designed to ensure that the structural components of 
each state's air quality management program are adequate to meet the 
state's responsibilities under the CAA.

DATES: As of November 17, 2017, the direct final rule published on 
September 29, 2017 (82 FR 45497), is withdrawn.

withdrawing the direct final rule to approve revisions to the Iowa 
State Implementation Plan (SIP). In the direct final rule published on 
September 29, 2017, (82 FR 45497), we stated that if we received
