Air Plan Approval; Iowa; State Implementation Plan and Operating 
Permits Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve revisions to the Iowa State Implementation Plan (SIP) and the 
Operating Permits Program. The revisions include updating definitions, 
clarifying permit rule exemptions and permit-by-rule regulations, 
revising methods and procedures for performance test/stack test and 
continuous monitoring systems, and updating the Prevention of 
Significant Deterioration (PSD) regulations and Operating Permits 
Program. In addition, the State has removed its rules that implement 
the Clean Air Interstate Rule (CAIR) and revised their acid rain rules. 
These revisions will not impact air quality and will ensure consistency 
between the state and Federally approved rules.

I. What is being addressed in this document?

    EPA is proposing to approve a submission from the State of Iowa to 
revise the Iowa SIP and the Operating Permits Program. The revisions to 
the Iowa SIP revise the definition for EPA reference method and 
volatile organic compounds (VOCs), clarifies permit rule exemptions and 
the State's permit-by-rule regulation, and revises methods and 
procedures for performance test/stack test and continuous monitoring 
systems. In addition, the State has removed its rules that implement 
the CAIR. The State has also revised their Prevention of Significant 
Deterioration (PSD) regulations to incorporate the most recent Federal 
requirements. Iowa has also revised their Operating Permits Program by 
revising the definition for EPA Reference Method, clarifying 
insignificant activities as applied to internal combustion engines, 
revising forms used to submit emission inventories and due dates as 
well as revising the public participation rules. In addition, the State 
revised their acid rain rules to include the most recent EPA Reference 
Method.
    EPA is not acting on Chapter 25.2--Continuous emission monitoring 
under the acid rain program, as these provisions are not approved in 
the operating permits program. EPA is also not acting on the New Source 
Performance Standards, emission standards for hazardous air pollutants, 
emission standards for hazardous air pollutants for source categories, 
and emission guidelines that were submitted in this SIP revision. These 
will be addressed separately.

II. What SIP revisions are being proposed by EPA?

    EPA is proposing the following revisions to the Iowa SIP:
    Chapter 20--Scope of Title-Definitions: The State revised the 
definition of ``EPA reference method,'' to adopt the most current EPA 
methods for measuring air pollutant emissions (stack testing and 
continuous monitoring). EPA revised the reference methods in 40 CFR 
parts 51, 60, 61 and 63 on August 30, 2016. These updates will ensure 
that state reference methods are equivalent to Federal reference 
methods and are no more stringent than Federal methods.
    The State revised the definition of ``volatile organic compounds'' 
(VOC) to reflect changes made to the Federal definition of VOC on 
August 1, 2016. EPA finalized a regulation on August 1, 2016, to 
exclude the compound 1,1,2,2-tetrafluoro-1-(2,2,2-trifluoroethoxy) 
Ethane (HFE-347pcf2) from the Federal definition because this compound 
makes a negligible contribution to tropospheric ozone formation. This 
revision to the VOC definition ensures consistency with the Federal 
definition.
    Chapter 22--Controlling Pollution: The State made three revisions 
under Chapter 22, ``Permits required for new or existing stationary 
sources,'' subrule 22.1(2), ``Permitting exemptions.'' The revisions to 
permitting exemptions do not relieve the owner or operator of any 
source from any obligation to comply with any other applicable 
requirements.
    The introductory paragraph to 22.1(2) ``i'', ``Initiation of 
construction, installation, reconstruction, or alteration 
(modification) to equipment,'' now cross-refers to subrule 31.3(1) in 
the Iowa SIP as the previous reference no longer exists. Subrule 
31.3(1) refers to definitions for nonattainment new source review 
requirements for areas designated nonattainment on or after May 18, 
1998.
    Subparagraph 22.1(2) ``r'', applies to the exemption for an 
internal combustion engine with a brake horsepower rating of less than 
400 measured at the shaft. The added

[[Page 49510]]

language (underlined below) clarifies that the owner or operator of an 
engine that was manufactured, ordered, modified or reconstructed after 
March 18, 2009, may use this exemption only if the owner or operator, 
prior to installing, modifying or reconstructing the engine, submits to 
the department a completed registration on forms provided by the 
department (unless the engine is exempted from registration, as 
specified in this paragraph or on the registration form). This revision 
clarifies that an engine that meets the definition of nonroad engine as 
specified in 40 CFR 1068.30,\1\ is exempt from registration 
requirements. The engine must be in compliance with New Source 
Performance Standards (NSPS) for stationary compression ignition 
internal combustion engines (40 CFR part 60, subpart IIII); NSPS for 
stationary spark ignition internal combustion engines (40 CFR part 60, 
subpart JJJJ), and National Emission Standards for Hazardous Air 
Pollutants for Reciprocating Internal Combustion Engines (40 CFR part 
63, subpart ZZZZ). The State also corrected punctuation errors in this 
subparagraph.
---------------------------------------------------------------------------

    \1\ https://www.ecfr.gov/cgi-bin/text-idx?SID=db4b0eb8f69070dfa866091c274c941c&mc=true&node=se40.37.1068_130&rgn=div8.
---------------------------------------------------------------------------

    Subparagraph 22.1(2)``w''(1) applies to ``small unit'' exemptions 
from construction permitting. The SIP-approved list of criteria has the 
word ``or'' between the last two items in the list, which could lead 
affected owners and operators to conclude that an emission unit does 
not need to meet all the criteria in the list. This proposed revision 
changes the word ``or'' to ``and'' between the provision for 
``PM2.5'' and the one for ``hazardous air pollutants'' in 
the list of air pollutants. A spelling error will also be corrected 
with this proposed revision.
    The revisions to subrule 22.8(1) ``a'', ``Permit by Rule,'' allow 
powder coat material to be used in paint booths without being 
considered ``sprayed material,'' provided the powder coating is applied 
in an indoor-vented spray booth equipped with filters or an overspray 
powder recovery system. Included in this docket are justification 
materials from the state that evaluates that particulate emissions from 
powder coatings specified under the conditions in permit by rule, would 
not contribute to the exceedances of the ambient air quality standards 
for particulate matter. The justification was previously provided in 
support of the exemption for powder coatings for construction permits 
(22.1(2)``bb''). Owners and/or operators using the permit by rule must 
send a notification letter to the Department and complete applicability 
questions for the facility. Facilities not eligible for permit by rule 
are required to apply for a construction permit as specified under 567 
IAC subrules 22.1(1) and 22.1(3).
    Chapter 25--Measurement of Emissions: The State revised subrule 
25.1(9), ``Methods and Procedures,'' to adopt the most current EPA 
reference methods for measuring air pollutant emissions (performance 
test/stack test, 25.1(9)a, and continuous monitoring systems, 
25.1(9)b). EPA revised the reference methods in 40 CFR parts 51, 60, 61 
and 63 on August 30, 2016. These proposed updates will ensure that 
state reference methods are equivalent to Federal reference methods and 
are no more stringent than Federal methods.
    Chapter 33--Special Regulations and Construction Permit 
Requirements for Major Stationary Sources--Prevention of Significant 
Deterioration (PSD) of Air Quality:
    33.1--Purpose. The State revised the applicable date to incorporate 
the recent changes EPA made to the Federal requirements of the PSD 
program from August 19, 2015, to October 18, 2016.
    33.1(3)--Definitions. The State revised the definition of 
``volatile organic compounds'' (VOC) to reflect changes made to the 
Federal definition of VOC on August 1, 2016. The compound 1,1,2,2-
tetrafluoro-1-(2,2,2-trifluoroethoxy) Ethane (HFE-347pcf2) was excluded 
from the Federal definition at 40 CFR 51.100(s) because this compound 
makes a negligible contribution to tropospheric ozone formation. This 
proposed revision to the state's VOC definition ensures consistency 
with the Federal definition.
    33.3(17)--Public participation. The State made revisions that 
addresses public participation requirements for the PSD program to 
reflect updates to the Federal regulations, at 40 CFR part 51, subpart 
I, published October 18, 2016. The revision removes the requirements 
for advertisement in a newspaper of general circulation in each region 
in which the proposed source will be constructed, and provides for 
posting of the public comment period on a website identified by the 
department.\2\ The electronic notice shall be available for the 
duration of the public comment period and include the notice of public 
comment, the draft permit(s), information on how to access the 
administrative record for the draft permit(s), and how to request or 
attend a public hearing on the draft permits(s). The revision also 
requires the department to be consistent in the method of providing 
public notice while using other means necessary to ensure adequate 
notice to the affected public.
---------------------------------------------------------------------------

    \2\ The ``department'' is the Iowa Department of Natural 
Resources and the permitting authority.
---------------------------------------------------------------------------

    33.3(22)--Permit rescission. This revision allows for rescission of 
PSD permits to be consistent with the Federal changes made to 40 CFR 
part 51, subpart I, published October 18, 2016, with regard to public 
participation. A notice of permit rescission may be posted on a 
publicly available website identified by the department.
    Chapter 34--Provisions for Air Quality Emissions Trading Programs. 
Due to the regulations being phased out and replaced with the Cross-
State Air Pollution Rule published in the Federal Register on August 8, 
2011 at 76 FR 48208, Iowa is implementing the Cross-State Air Pollution 
Rule through a Federal Implementation Plan, and removing its 
regulations that implement CAIR. Because the State CAIR trading 
programs created by these rules are no longer being implemented, and 
because the rules serve no other purpose, removal of the rules from the 
SIP does not interfere with any applicable requirement concerning 
attainment or any other requirement of the CAA.
    EPA is proposing to approve the rescission of the following 
chapters in the Iowa SIP:
    34.201, CAIR NOX Annual Trading Program Provisions;
    34.202, CAIR Designated Representative for CAIR NOX 
sources;
    34.203, Permits;
    34.204, Reserved;
    34.205, CAIR NOX Allowance Allocations;
    34.206, CAIR NOX Allowance Tracking System;
    34.207, CAIR NOX Allowance Transfers;
    34.208, Monitoring and Reporting;
    34.209, CAIR NOX Opt-in Units;
    34.210, CAIR SO2 Trading Program;
    34.211-34.219, Reserved;
    34.220, CAIR NOX Ozone Season Trading Program;
    34.221, CAIR NOX Ozone Season Trading Program General 
Provisions;
    34.222, CAIR Designated Representative for CAIR NOX 
Ozone Season Sources;
    34.223, CAIR NOX Ozone Season Permits;
    34.224, Reserved;
    34.225, CAIR NOX Ozone Season Allowance Allocations;
    34.226, CAIR NOX Ozone Season Allowance Tracking System;
    34.227, CAIR NOX Ozone Season Allowance Transfers;
    34.228, CAIR NOX Ozone Season Monitoring and Reporting, 
and 34.229, CAIR NOX Ozone Season Opt-in Units.

III. What operating permits plan revisions are being proposed by EPA?

    EPA is proposing to approve the following revisions to Iowa's 
Operating Permits Program (Title V) as follows:
    Chapter 22.100--Definitions for Title V Operating Permits: The 
State revised the definition of ``EPA reference method,'' to adopt the 
most current EPA methods for measuring air pollutant emissions (stack 
testing and continuous monitoring). EPA revised the reference methods 
in 40 CFR parts 51, 60, 61 and 63 on August 30, 2016. These updates 
will ensure that state reference methods are equivalent to Federal 
reference methods and are no more stringent than Federal methods.
    Chapter 22.103--Insignificant activities:
    Subparagraph 22.103(2)``b''(6) applies to the exemption for 
internal combustion engines that are used for emergency response 
purpose with a brake horsepower rating of less than 400 measured at the 
shaft. The revision adds that emergency engines that are subject to the 
following rules are not to be considered insignificant: New Source 
Performance Standards (NSPS), 40 CFR part 60 subpart IIII (stationary 
compression ignition internal combustion engines); NSPS 40 CFR part 60, 
subpart JJJJ (stationary spark ignition internal combustion engines), 
and National Emission Standards for hazardous air pollutants, 40 CFR 
part 63, subpart ZZZZ (reciprocating internal combustion engines).
    Chapter 22.106, Title V permit fees:
    The revision to 22.106(2) applies to emission inventories and 
documentation due dates. The revision specifies that emissions 
inventories will be submitted with forms specified by the department. 
For emissions in Polk and Linn Counties, three copies of forms should 
be submitted that document actual emissions for the previous calendar 
year annually by March 31. Emissions in other counties are required to 
submit two copies of forms documenting actual emissions for the 
previous calendar year annually by March 31. With this revision, the 
following forms have been removed: Form 1.0, ``Facility 
Identification''; Form 4.0, ``Emission Unit--Actual Operations and 
Emissions'' for each emission unit; Form 5.0, ``Title V Annual 
Emissions Summary/Fee'', and Part 3, ``Application Certification.''
    Chapter 22.107, Title V permit processing procedures:
    The revision to subrule 22.107(6), ``Public notice and public 
participation,'' updates the Title V program to reflect the changes 
made to Federal regulations at 40 CFR 70.7(h), published October 18, 
2016. The revision removes the requirements for advertisement in a 
newspaper of general circulation and adds that posting of the notice, 
including the draft permit, for the duration of the public comment 
period on a public website identified by the permitting authority.\3\
---------------------------------------------------------------------------

    \3\ Iowa Department of Natural Resources.
---------------------------------------------------------------------------

    Chapter 22.120: This chapter applies to the acid rain program. In 
Iowa, all provisions of the acid rain program are approved under the 
Title V Operating Permits Program. Therefore, the test methods as 
applied in Chapter 22.100 apply to Chapter 22.120 to include the most 
recent EPA reference method revision to 40 CFR part 75 (August 30, 
2016).
    Chapter 30--Fees: The revision to ``Fees Associated with Title V 
Operating Permits'' at 30.4(2) ``b'' removes the following forms: Form 
1.0, ``Facility Identification''; Form 5.0, ``Title V Annual Emissions 
Summary/Fee'', and Part 3, ``Application Certification.'' The revision 
also adds the language ``with forms specified by the department.''

IV. Have the requirements for approval of a SIP and the Operating 
Permits Program revisions been met?

    The submission met the public notice requirements for SIP 
submissions in accordance with 40 CFR 51.102. The State held a public 
comment period from December 20, 2017 to January 22, 2018, with a 
public hearing on January 22, 2018. No comments were received. The 
submissions also satisfied the completeness criteria of 40 CFR part 51, 
appendix V. In addition, 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 Title V of the CAA and 40 CFR part 70.

V. What actions are proposed?

    EPA is proposing to approve revisions to the Iowa SIP and the 
Operating Permits Program. The proposed revisions clarify rules, makes 
revisions and corrections, and rescinds rules no longer relevant to the 
air program. EPA has determined that approval of these revisions will 
not impact air quality and will ensure consistency between the state 
and federally-approved rules, and ensure Federal enforceability of the 
state's revised air program rules.

VI. Incorporation by Reference

    In this document, EPA is proposing to include regulatory text in an 
EPA final rule that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, EPA is proposing to incorporate by 
reference the Iowa Regulations described in the proposed amendments to 
40 CFR part 52 set forth below. EPA has made, and will continue to 
make, these materials generally available through www.regulations.gov 
and at the EPA Region 7 Office (please contact the person identified in 
the For Further Information Contact section of this preamble for more 
information).

VII. Statutory and Executive Order Reviews

    Under the Clean Air Act (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);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866.
     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

[[Page 49512]]

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).
