for the 2010 Nitrogen 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 Nitrogen Dioxide National Ambient Air Quality 
Standard (NAAQS) published in the Federal Register on September 20, 
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: The direct final rule published at 82 FR 43846, September 20, 
2017, is withdrawn effective November 17, 2017.

State Implementation Plan (SIP). In the direct final rule published on
