[EPA-R07-OAR-2017-0470; FRL-9967-52-Region 7]

State of Iowa; Approval and Promulgation of the State 
Implementation Plan, the 111(d) Plan, and the Operating Permits Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking direct 
final action to approve revisions to the Iowa State Implementation Plan 
(SIP), the 111(d) plan, and the Operating Permits Program. These 
revisions update and clarify rules and make minor revisions and 
corrections. Approval of these revisions will ensure consistency 
between the state and Federally-approved rules, and ensure Federal 
enforceability of the state's revised air program rules. EPA is taking 
direct final action because we view this as a noncontroversial action 
and anticipate no relevant adverse comment. We have explained our 
reasons for these actions in the Technical Support Document (TSD) that 
is included in this docket.

DATES: This direct final rule is effective November 14, 2017, without 
further notice, unless EPA receives adverse comment by October 16, 
2017. If EPA receives adverse comment, we will publish a timely 
withdrawal of the direct final rule in the Federal Register informing 
the public that the rule will not take effect.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R07-
OAR-2017-0470, 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. EPA will 
generally not consider comments or comment contents located outside of

I. What is being addressed in this document?

    EPA is taking direct final action to approve revisions to the Iowa 
SIP, the 111(d) plan, and the Operating Permits Program. These 
revisions update and clarify rules and make minor revisions and 
corrections. Approval of these revisions will ensure consistency 
between the state and Federally-approved rules, and ensure Federal 
enforceability of the state's revised air program rules. Chapters with 
revisions are as follows:

 Chapter 20--Scope of Title--Definitions
 Chapter 21--Compliance
 Chapter 22--Controlling Pollution*
 Chapter 23--Emission Standards for Contaminants
 Chapter 25--Measurement of Emissions
 Chapter 26--Prevention of Emergency Pollution Episodes
 Chapter 27--Certificate of Acceptance
 Chapter 28--Ambient Air Quality Standards
 Chapter 31--Nonattainment Areas
 Chapter 33--Special Regulations and Construction Permit 
Requirements for Major Stationary Sources--Prevention of Significant 
Deterioration (PSD) of Air Quality

    * Title V Operating Permit Program rules are included in Chapter 22 
starting at 22.100.

II. What SIP revisions are being approved by EPA?

    EPA is approving SIP revisions submitted by the state of Iowa to 
update and clarify rules, and make minor revisions and corrections. EPA 
analyzed the SIP revisions and determined that air quality will not be 
impacted, and revisions are consistent with Federal regulations. 
Revisions to the SIP are as follows:
    The title to chapter 20 is revised to ``Scope of Title--
Definitions,'' which more accurately describes what is included in the 
Chapter. With the chapter title revision, the summaries of each chapter 
of the air quality rules are revised at 20.1. The definition of EPA 
reference method (20.2) is revised to adopt the most current Federal 
revisions to EPA methods for measuring air pollutant emissions.
    Subrule 21.1(4) of the SIP is rescinded. This subrule applied to 
the emission inventory requirements for the Clean Air Interstate Rule 
which was rescinded by EPA. The rescission of this rule does not impact 
air quality.
    With regard to chapter 22 which addresses permitting requirements 
for existing sources, a revision is made to 22.1(1)``b'' to remove the 
Federal amendment date for the referenced Federal regulation, and adds 
language to refer to the state rule in which the Federal regulation is 
adopted by reference. This revision removes redundancy from the state 
rules. A revision is made to 22.1(1)``c''(2) to adopt the most recent 
changes to Federal air quality control strategies for lead.
    Subrule 22.1(2) revisions update exemptions from construction 
permitting in the introductory paragraph to clarify that facilities 
applying for plantwide applicability limitations as specified in rule 
33.9, are eligible to use construction permitting exemptions. The fuel-
burning

[[Page 43304]]

equipment exemption (22.1(2)``b'') is revised to add ``indirect'' 
cooling to be consistent with Federal regulations. The air compressors 
and vacuum pumps exemption (22.1(2)``x'') are revised to remove a 
misplaced comma; the production welding exemption (22.1(2)``ff'') is 
revised to correct an error in a technical equation, and the non-road 
diesel fuel engines with a brake horsepower rating of less than 1,100 
at full load exemption, (22.1(2)``oo'') is updated to correct grammar 
and to revise the reference to Federal regulations. The revisions to 
exemptions to construction permitting do not impact air quality.
    Revisions are being made to 22.1(3) to revise the number of copies 
of construction permit applications. Clarification with regard to new 
or modified anaerobic lagoon construction permits directs the reader to 
567--chapter 65, which are regulations for animal feeding operating and 
are not subject to the air permitting rules in 567--chapter 22. 
Paragraph 22.1(3)``b'' is revised to include instructions for 
submitting applications on forms available from the Web site.
    Subrule 23.3(1) (Specific contaminants--general) is revised to 
clarify that facility operations subject to new source performance 
standards are not subject to the emission standards specified in rule 
23.3.
    Chapter 25--Measurement of Emissions--is revised at 25.1(9) to 
adopt revised Federal methods for emissions testing and monitoring, and 
adds language to clarify the alternative methodology for performance 
test (stack test) and continuous monitoring systems. This revision 
insures that only current Federal test methods are used to demonstrate 
compliance with permit conditions and that required test methods are no 
more stringent than Federal methods.
    Revisions to chapter 26--Prevention of Air Pollution Emergency 
Episodes--reflect the current Federal levels and terminology for air 
pollution emergency episodes for ozone and particulate matter that are 
used in making determinations for the declaration of an emergency 
episode condition. A punctuation correction is being made to 
``Declarations.'' The revisions are consistent with Federal regulations 
and do not impact air quality.
    Chapter 27 applies to political subdivisions. Revisions are being 
made to 27.1(2), to correct the reference to the Iowa Administrative 
Code (455B.139) as it applies to emergency orders. Revisions to 
27.3(4)``c'' ensure the local programs variance procedures and rules 
are consistent with the state's, which were approved in to the SIP in 
1972 and revised through 2007.
    Revisions to chapter 28--State-wide standards--adopt by reference 
revisions to the National Ambient Air Quality Standards (NAAQS) for 
PM2.5. The PM2.5 standard was revised in 2012 to 
increase protection to public health and the environment. Iowa 
determined that no other changes to air quality rules are needed to 
implement the revised NAAQS for PM2.5.
    The general conformity rule at 31.2 is rescinded and reserved. The 
requirement for states to include general conformity requirements in 
any SIP submitted for a nonattainment area was eliminated in 2005. The 
rescission of this rule does not impact air quality.
    Chapter 33 applies to special regulations and construction permit 
requirements for major stationary sources--prevention of significant 
deterioration (PSD) of air quality. The introductory paragraph to 33.1, 
the definition of ``subject to regulation'' (33.3(1)), ``exemptions'' 
(33.3(9)), and ``source impact analysis'' (33.3(11)) are revised to 
reflect Federal revisions to the PSD program. ``Subject to regulation'' 
(33.3(1)) is also revised to remove thresholds as related to greenhouse 
gases. This revision is identical to the changes EPA made to Federal 
PSD regulations on August 19, 2015. An inaccurate table title is 
removed at 33.3(20), (``Conditions for permit issuance'').
    Subrule 33.3(22)--Permit Rescission--is revised to allow for 
rescission of PSD permits that are no longer required for a source 
classified as a major for PSD solely because of the source's greenhouse 
gas emissions, or for a source emitting major levels of other 
pollutants that underwent a modification resulting in an increase of 
only greenhouse gas emissions above the levels specified for a major 
modification. This revision is consistent with Federal revisions to the 
PSD program in 40 CFR 52.21(w) published on May 7, 2015 and August 19, 
2015.

III. What 111(d) plan revisions are being approved by EPA?

    EPA is approving a revision to Iowa's 111(d) plan for municipal 
solid waste landfill emissions to correct an error in the emission 
guidelines to clarify that landfills must meet both the size and weight 
requirements indicated in 23.1(5)``a''(3)``1''.

IV. What operating permit plan revisions are being approved by EPA?

    EPA is approving revisions to Iowa's operating permits program 
submitted by the state of Iowa to update and clarify rules, and make 
minor revisions and corrections.
    The following definitions (22.100) are revised to update references 
to current Federal regulations: ``Designated representative,'' ``EPA 
reference method,'' and ``Subject to regulation.'' In addition to 
revising the updated reference to Federal regulations, ``Existing 
hazardous air pollutant source,'' and ``High-risk pollutant'' are 
revised to remove the Federal amendment dates and add cross-references 
to state rules that are adopted by reference. ``Major source'' is 
revised to add ``or treated as classified'' to major stationary sources 
in nonattainment areas.
    Subrule 22.103(2)``b'' which refers to insignificant activities 
under the operating permits program, is revised to add indirect cooling 
to the description of fuel-burning equipment that may be classified as 
an insignificant activity, and updates the references to Federal 
regulations for burning used oil.
    Rule 22.105--Title V permit applications--is revised to update the 
address of the EPA Region 7 regional office, and adds that facilities 
that submitted a Title V application with a previously-submitted annual 
emissions inventory need not resubmit the emissions inventory.
    Rule 22.108--Permit content--is revised to include the most recent 
reference to Federal regulations.

V. Have the requirements for approval of the SIP, 111(d) plan, and 
operating permit plan revisions been met?

    The state submittal has met the public notice requirements for SIP 
submissions in accordance with 40 CFR 51.102. The submittal also 
satisfied the completeness criteria of 40 CFR part 51, appendix V. In 
addition, as explained previously and in more detail in the TSD which 
is part of this docket, these revisions meet the substantive SIP 
requirements of the CAA, including section 110 and implementing 
regulations. These revisions are also consistent with applicable EPA 
requirements of the 111(d) plan submission and Title V of the CAA and 
40 CFR part 70.

VI. What action is EPA taking?

    EPA is taking direct final action to approve revisions to the Iowa 
State Implementation Plan (SIP), the 111(d) plan, and the Operating 
Permits Program. These revisions update and clarify rules and makes 
minor revisions and corrections. Approval of these revisions will 
ensure consistency between the state and Federally-approved rules, and 
ensure Federal

[[Page 43305]]

enforceability of the state's revised air program rules. EPA is taking 
direct final action because we view this as a noncontroversial action 
and anticipate no relevant adverse comment. We have explained our 
reasons for these actions in the TSD that is included with this docket.
    However, in the ``Proposed Rules'' section of this Federal 
Register, we are publishing a separate document that will serve as the 
proposed rule to approve the SIP revision if adverse comments are 
received on this direct final rule. We will not institute a second 
comment period on this action. Any parties interested in commenting 
must do so at this time. For further information about commenting on 
this rule, see the ADDRESSES section of this document. If EPA receives 
adverse comment, we will publish a timely withdrawal in the Federal 
Register informing the public that this direct final rule will not take 
effect. We will address all public comments in any subsequent final 
rule based on the proposed rule.

VII. Incorporation by Reference

    In this rule, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, EPA is finalizing the incorporation by reference of the Iowa 
Regulations described in the direct final amendments to 40 CFR part 52 
set forth below. Therefore, these materials have been approved by EPA 
for inclusion in the SIP, have been incorporated by reference by EPA 
into that plan, are fully Federally enforceable under sections 110 and 
113 of the CAA as of the effective date of the final rulemaking of 
EPA's approval, and will be incorporated by reference by the Director 
of the Federal Register in the next update to the SIP compilation.\1\ 
EPA has made, and will continue to make, these materials generally 
available through https://www.regulations.gov and/or at the EPA Region 
7 Office (please contact the person identified in the FOR FURTHER 
INFORMATION CONTACT; section of this preamble for more information).

VIII. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting Federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:
     Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Orders 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    The SIP is not approved to apply on any Indian reservation land or 
in any other area where EPA or an Indian tribe has demonstrated that a 
tribe has jurisdiction. In those areas of Indian country, the rule does 
not have tribal implications and will not impose substantial direct 
costs on tribal governments or preempt tribal law as specified by 
Executive Order 13175 (65 FR 67249, November 9, 2000).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by November 14, 2017. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this action for the purposes of judicial review nor 
does it extend the time within which a petition for judicial review may 
be filed, and shall not postpone the effectiveness of such rule or 
action. This action may not be challenged later in proceedings to 
enforce its requirements. (See section 307(b)(2)).
