Region 7] 

Approval of Iowa Air Quality 

Implementation Plans; Elements of the 

Infrastructure SIP Requirements for 

the 2012 Annual Fine Particulate Matter 

(PM2.5) National Ambient Air Quality 

Standard (NAAQS) 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is proposing to approve 

elements of a State Implementation Plan 

(SIP) submission from the State of Iowa 

for the 2012 Annual Fine Particulate 

Matter (PM2.5) National Ambient Air 

Quality Standard (NAAQS). 

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. 

In the ‘‘Rules and Regulations’’ 

section of this issue of the Federal 

Register, we are approving the state’s 

SIP revisions as a direct final rule 

without a prior proposed rule. If we 

receive no adverse comment, we will 

not take further action on this proposed 

rule. 

DATES: Comments must be received on 

or before October 30, 2017. 

ADDRESSES: Submit your comments, 

identified by Docket ID No. EPA–R07– 

OAR–2017–0517, to https://

www.regulations.gov. Follow the online 

instructions for submitting comments. 

Once submitted, comments cannot be 

edited or removed from Regulations.gov. 

EPA may publish any comment received 

to its public docket. Do not submit 

electronically any information you 

consider to be Confidential Business 

Information (CBI) or other information 

whose disclosure is restricted by statute. 

Multimedia submissions (audio, video, 

etc.) must be accompanied by a written 

comment. The written comment is 

considered the official comment and 

should include discussion of all points 

you wish to make. The EPA will 

generally not consider comments or 

comment contents located outside of the 

primary submission (i.e., on the Web, 

cloud, or other file sharing system). For 

additional submission methods, the full 

EPA public comment policy,

SUPPLEMENTARY INFORMATION: This 

document proposes to take direct final 

action on Iowa’s infrastructure SIP 

submissions for the 2010 NO2 NAAQS. 

We have published a direct final rule 

approving the State’s SIP revisions in 

the ‘‘Rules and Regulations’’ section of 

this issue of the Federal Register, 

because we view this as a 

noncontroversial action and anticipate 

no relevant adverse comment. We have 

explained our reasons for this action in 

the preamble to the direct final rule. A 

detailed technical support document 

(TSD) is included in this rulemaking 

docket to address the following: A 

description of Clean Air Act section 

110(a)(1) and (2) infrastructure SIPs; the 

applicable elements under sections 

110(a)(1) and (2); EPA’s approach to the 

review of infrastructure SIP 

submissions, and EPA’s evaluation of 

how Iowa addressed the relevant 

elements of sections 110(a)(1) and (2). If 

we receive no adverse comment, we will 

not take further action on this proposed 

rule. If we receive adverse comment, we 

will withdraw the direct final rule and 

it will not take effect. We would address 

all public comments in any subsequent 

final rule based on this proposed rule. 

We do not intend to institute a second 

comment period on this action. Any 

parties interested in commenting must 

do so at this time. For further 

information, please see the information 

provided in the ADDRESSES section of 

this document.
