SUPPLEMENTARY INFORMATION: Throughout this document, whenever ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean EPA. This supplementary information section is arranged as follows: I. The 2008 Ozone NAAQS Emissions Inventory and Emissions Statement Rule Requirements II. Indiana’s Emissions Inventory III. Indiana’s Emissions Statement Rule Certification IV. EPA’s Evaluation V. Final Action VI. Statutory and Executive Order Reviews I. The 2008 Ozone NAAQS Emissions Inventory and Emissions Statement Rule Requirements On March 12, 2008, EPA promulgated a revised 8-hour ozone NAAQS of 0.075 parts per million (ppm). See 73 FR 16436 (March 27, 2008). On July 20, 2012, EPA designated nonattainment areas for the 2008 ozone NAAQS (77 FR 30088, May 21, 2012, and 77 FR 34221, June 11, 2012). The Chicago-Naperville, IL–IN–WI area was designated as a marginal nonattainment area for the 2008 ozone NAAQS. The Indiana portion of this ozone nonattainment area consists of Lake and Porter Counties. A. Emissions Inventories CAA sections 172(c)(3) and 182(a)(1), 42 U.S.C. 7502(c)(3) and 7511a(a)(1), require states to develop and submit, as SIP revisions, comprehensive, accurate, and complete emissions inventories for all areas designated as nonattainment for the ozone NAAQS. An emissions inventory for ozone is an estimation of actual emissions of air pollutants that contribute to the formation of ozone in an area. Ozone is a gas that is formed by the reaction of Volatile Organic Compounds (VOC) and Oxides of Nitrogen (NOX) in the atmosphere in the presence of sunlight (VOC and NOX are referred to as ozone precursors). Therefore, an emissions inventory for ozone covers the emissions of VOC and NOX within an ozone nonattainment area. VOC is emitted by many types of pollution sources, including power plants, industrial sources, on-road and off-road mobile sources, smaller stationary sources, collectively referred to as area sources, and biogenic sources.1 NOX is primarily emitted by combustion sources, both stationary and mobile. The emissions inventory provides emissions data for a variety of air quality planning tasks, including establishing baseline emission levels for calculating emission reduction targets needed to attain the NAAQS and for calculating emission reduction targets needed to meet Reasonable Further Progress (RFP) requirements, determining emission inputs for ozone air quality modeling analyses, and tracking emissions over time to determine progress toward achieving air quality and emission reduction goals. As stated above, the CAA requires the states to submit emissions inventories for areas designated as nonattainment for ozone. For the 2008 ozone NAAQS, EPA has recommended that states use 2011 as a base year for the emissions estimates (78 FR 34178, 34190, June 6, 2013). However, EPA also allows states to submit base year emissions for other years during a recent ozone standard violation period. States are required to submit estimates of VOC and NOX emissions for four general classes of anthropogenic sources in their emissions inventories: Stationary point sources; area sources; on-road mobile sources; and off-road mobile sources. B. Emissions Statement Rules Section 182(a)(3)(B) of the CAA requires states with ozone 16935 nonattainment areas to submit revisions to their SIP to require the owner or operator of each major stationary source of NOX or VOC to provide the state with an annual statement documenting the actual emissions of NOX and VOC from their source. Under section 182(a)(3)(B)(ii), a state may waive the emissions statement requirement for any class or category of stationary sources which emits less than 25 tons per year of VOC or NOX if the state, in its base year emissions inventory, provides an inventory of emissions from such class or category of sources. States and EPA have generally interpreted this waiver provision to apply to sources (without specification of a specific source class or source category) emitting less than 25 tons per year of VOC or NOX. Many states adopted these emissions statement rules for the 1-hour ozone NAAQS. For these states, EPA is accepting certifications that their previously adopted emissions statement rules remain in place and are adequate to meet the emissions statement rule requirement under the 2008 ozone standard. II. Indiana’s Emissions Inventory On June 15, 2016, IDEM submitted an ozone redesignation request for Lake and Porter Counties for the 2008 ozone NAAQS. Included in this request was documentation of a 2011 VOC and NOX base year emissions inventory for Lake and Porter Counties intended to meet the emissions inventory requirement of CAA section 182(a)(1). Preliminary monitoring data for 2016 indicates that the Chicago-Naperville, IL–IN–WI area is violating the 2008 ozone standard with 2014–2016 data. Therefore, EPA is not taking action on the ozone redesignation request portion of this June 15, 2016, submittal at this time. We are, however, proceeding with rulemaking on the base year VOC and NOX emissions inventory portion of the submittal. Table 1 summarizes the 2011 VOC and NOX emissions for Lake and Porter Counties in units of tons of emissions per ozone season 2 day documented in Indiana’s submittal.

To document the derivation of these emissions data, IDEM included EPA’s ‘‘Technical Support Document (TSD) Preparation of Emissions Inventories for the Version 6.2 2011 Emissions Modeling Platform’’ (August 2015) in the June 15, 2016, submittal. The Ozone NAAQS Emissions Modeling Platform (2011v6.2) was used by EPA to collect or estimate emissions data for the 2011 NEI. For point sources (EGUs and nonEGUs), IDEM calculates and stores emissions data annually in the state’s Emissions Inventory Tracking System (EMITS) and annually collects such data through Indiana’s Emissions Statement program. The point source data for 2011 were submitted through the Emissions Inventory System (EIS) gateway to the 2011 NEI. The EPA has supplemented the point source data in the 2011 NEI using emissions data from other databases, such as the Clean Air Markets emissions database. The area source emissions in the 2011 NEI were developed by the EPA, with comments provided by the states. Non-road mobile source emissions data were developed by the EPA using the National Mobile Inventory Model (NMIM). On-road mobile source emissions were supplied by the Northwest Indiana Regional Planning Commission (NIRPC) and were developed using EPA’s Motor Vehicle Emission Simulator, version 2014 (MOVES2014), emissions model and traffic data provided by the Indiana Department of Transportation (INDOT). All annual emissions data were temporally allocated to ozone season days using temporal files found in EPA’s Modeling Clearinghouse, https:// www3.eap.gov/ttn/chief/emch/ index.html. VerDate Sep<11>2014 18:05 Apr 06, 2017 Jkt 241001 NOX VOC County It is noted that, in addition to documenting county emissions totals, IDEM has also listed VOC and NOX emissions by Source Classification Code (SCC) and emissions from specific major source facilities (point sources). III. Indiana’s Emissions Statement Rule Certification On June 15, 2016, through a separate submittal, IDEM submitted a certification letter confirming that Indiana’s existing Emissions Reporting Rule is currently being implemented and is adequate to meet the CAA section 182(a)(3)(B) emissions reporting requirement. IDEM noted that the Emissions Reporting Rule, 326 Indiana Administrative Code (IAC) 2–6, was adopted by Indiana’s Air Pollution Control Board (APCB) on December 3, 2003. This rule is part of Indiana’s SIP. The rule requires sources located in Lake and Porter Counties that emit either NOX or VOC equal to or greater than 25 tons per year to annually report their actual emissions to IDEM. IDEM has certified in its June 15, 2016, letter that 326 IAC 2–6 satisfies CAA section 182(a)(3)(B) emissions reporting requirements for Lake and Porter Counties for the 2008 ozone NAAQS. Included with the certification letter is a copy of rule 326 IAC 2–6. IV. EPA’s Evaluation A. Emissions Inventory In accordance with sections 172(c)(3) and 182(a)(1) of the CAA, Indiana’s submittal contains a comprehensive, accurate, and current inventory of actual VOC and NOX emissions for all relevant sources in Lake and Porter Counties. The state documented the general procedures used to estimate the ozone season day emissions for each of the major source categories and for SCCs and point source facilities. IDEM provided detailed model input data used to derive on-road emissions. The documentation of the emissions PO 00000 Frm 00046 Fmt 4700 Sfmt 4700 estimation procedures and data sources has been determined to be adequate. IDEM has submitted evidence that it provided the public with an opportunity to request a public hearing and to comment on the material contained in the June 15, 2016, submittal. A public hearing was not requested and IDEM received no comments on the submission. Therefore, the state has complied with public notice and review requirements of the CAA. Based on the adequacy of the emissions inventories documentation and on the evidence that the public has been given an opportunity to comment on the emissions inventories, the base year emissions inventories are approvable. B. Emissions Statement Rule EPA approved Indiana’s emissions statement rule, 326 IAC 2–6, into the Indiana SIP on March 27, 2007 (72 FR 14678), and it is currently being implemented. The rule requires sources of VOC and NOX in Lake and Porter Counties to annually report these emissions to the state if the sources emit VOC or NOX equaling or exceeding 25 tons per year. In addition, it is noted that Indiana typically reports point source emissions to the NEI with source cutoffs well below 25 tons per year, covering VOC and NOX emissions from sources that are not required to submit annual emissions statements. Therefore, Indiana’s rule 326 IAC 2–6 meets the requirements of CAA section 182(a)(3)(B) and is approvable. V. Final Action EPA is approving the emissions inventory submitted by Indiana and specified in Table 1 above as meeting the requirements of sections 172(c)(3) and 182(a)(1) of the CAA for Lake and Porter Counties for the 2008 ozone NAAQS. We are also approving Indiana’s certification that the state has an emissions statement rule in its SIP for VOC and NOX stationary sources in E:\FR\FM\07APR1.SGM 07APR1 Federal Register / Vol. 82, No. 66 / Friday, April 7, 2017 / Rules and Regulations Lake and Porter Counties, in accordance with the CAA section 182(a)(3)(B). We are publishing this action without prior proposal because we view this as a noncontroversial amendment and anticipate no adverse comments. However, in the proposed rules section of this Federal Register publication, we are publishing a separate document that will serve as the proposal to approve the state plan if relevant adverse written comments are filed. This rule will be effective June 6, 2017 without further notice unless we receive relevant adverse written comments by May 8, 2017. If we receive such comments, we will withdraw this action before the effective date by publishing a subsequent document that will withdraw the final action. All public comments received will then be addressed in a subsequent final rule based on the proposed action. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that, if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment. If we do not receive any comments, this action will be effective June 6, 2017. nlaroche on DSK30NT082PROD with RULES VI. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA 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.); VerDate Sep<11>2014 14:50 Apr 06, 2017 Jkt 241001 • 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). In addition, 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 June 6, 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 PO 00000 Frm 00047 Fmt 4700 Sfmt 4700 16937 time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today’s Federal Register, rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)

ACTION: Final rule. AGENCY: The Environmental Protection Agency (EPA) is redesignating the Ohio portion of the Cincinnati-Hamilton, OH–IN–KY, nonattainment area (hereafter, ‘‘the Cincinnati-Hamilton area’’) to attainment for the 1997 fine particulate matter (PM2.5) annual national ambient air quality standards (NAAQS or standard). The Ohio portion of the Cincinnati-Hamilton area includes Butler, Clermont, Hamilton, and Warren Counties. Because EPA has determined that the CincinnatiHamilton area is attaining the annual PM2.5 standard, EPA is redesignating the area to attainment and also approving several additional related actions. EPA is approving the Reasonably Available Control Measures (RACM)—Reasonably Available Control Technology (RACT) portion of Ohio’s Cincinnati-Hamilton area attainment plan state implementation plan (SIP) revision as providing adequate RACM/RACT. EPA is also approving an update to the Ohio SIP, by updating the state’s approved plan for maintaining the 1997 annual PM2.5 NAAQS through 2027. EPA previously approved the base year emissions inventory for the CincinnatiHamilton area, and is approving Ohio’s updated emission inventory which includes emission inventories for volatile organic compounds (VOCs) and ammonia. Ohio’s approved maintenance plan submission includes a budget for the mobile source contribution of PM2.5 and nitrogen oxides (NOX) to the Cincinnati-Hamilton area for transportation conformity purposes, which EPA is approving.

Response to Comments III. What action is EPA taking? IV. Statutory and Executive Order Reviews I. Background On July 22, 2016, Ohio EPA submitted a request to EPA to redesignate the Cincinnati-Hamilton area to attainment for the 1997 PM2.5 annual standard, and to approve updates to the maintenance plan for the area. In a notice published on January 4, 2017 (82 FR 792), EPA proposed to redesignate the area and approve several actions related to the redesignation (82 FR 792). Additional background and details regarding this final action can be found in the January 4, 2017, proposed rule. II. Response to Comments Comment: EPA received one comment on the proposed redesignation. The commenter supported EPA’s proposal to redesignate the Ohio portion of the Cincinnati-Hamilton area. PO 00000 Frm 00048 Fmt 4700 Sfmt 4700 Response: EPA agrees with the comment, and no changes were made to the final action based on this comment. III. What action is EPA taking? EPA is taking several actions related to redesignation of the CincinnatiHamilton area to attainment for the 1997 annual PM2.5 NAAQS. EPA has previously approved Ohio’s PM2.5 maintenance plan and motor vehicle emission budgets for the Cincinnati-Hamilton area. EPA has determined that this plan and budgets are still applicable. EPA has previously approved the 2005 primary PM2.5, NOX, and SO2 base year emissions inventory. EPA is approving Ohio’s updated emissions inventory which includes emissions inventories for VOCs and ammonia from 2007. EPA has determined that Ohio meets the emissions inventory requirement under section 107(d)(3)(E)(iii). EPA is approving the RACM/RACT portion of Ohio’s prior CincinnatiHamilton area attainment plan SIP revision as providing adequate RACM/ RACT consistent with the provisions of 40 CFR 51.1010(b), because Ohio has demonstrated with a RACM/RACT analysis that no further control measures would advance the attainment date in the area. In The Fine Particulate Matter National Ambient Air Quality Standards: State Implementation Plan Requirements final rule (final PM2.5 SIP requirements rule), EPA revoked the 1997 primary annual PM2.5 NAAQS in areas that had always been attainment for that NAAQS, and in areas that had been designated as nonattainment but that were redesignated to attainment before October 24, 2016, the rule’s effective date. (See 81 FR 58010, August 24, 2016.) EPA also finalized a provision that revokes the 1997 primary annual PM2.5 NAAQS in areas that are redesignated to attainment for that NAAQS after October 24, 2016, effective on the effective date of the redesignation of the area to attainment for that NAAQS. (See 40 CFR 50.13(d).) EPA is redesignating the Ohio portion of the Cincinnati-Hamilton area to attainment for the 1997 annual PM2.5 NAAQS and approving the CAA section 175A maintenance plan for the 1997 primary annual PM2.5 NAAQS for the reasons described elsewhere in the January 4, 2017, proposed action.1 The 1 CAA section 175A(a) establishes the requirements that must be fulfilled by nonattainment areas in order to be redesignated to attainment. That section only requires that nonattainment areas for the primary standard submit a plan addressing maintenance of the E:\FR\FM\07APR1.SGM 07APR1

Air Plan Approval; Indiana; Base Year Emissions Inventory and
Emissions Statement Rule Certification for Lake and Porter Counties for
the 2008 Ozone Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving two
State Implementation Plan (SIP) submissions from the Indiana Department
of Environmental Management (IDEM), both dated June 15, 2016. The first
addresses emissions inventory requirements for the Indiana portion of
the Chicago-Naperville, Illinois-Indiana-Wisconsin (IL-IN-WI) ozone
nonattainment area under the 2008 ozone National Ambient Air Quality
Standard (NAAQS). The Clean Air Act (CAA) requires emissions
inventories for all ozone nonattainment areas. The documented emissions
inventory included in Indiana's June 15, 2016, submission meets this
CAA requirement. The second submission provides Indiana's certification
that its existing Emissions Reporting Rule, previously approved by EPA
under a prior ozone standard, satisfies the CAA emissions statement
rule requirement for Lake and Porter Counties under the 2008 ozone
standard.

DATES: This direct final rule will be effective June 6, 2017, unless
EPA receives adverse comments by May 8, 2017. If adverse comments are
received by EPA, EPA 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-R05-
OAR-2016-0370 (Emissions Statement) or by Docket ID No. EPA-R05-OAR-
2016-0371 (Emissions Inventory) at https://www.regulations.gov or via
email to aburano.douglas@epa.gov. For comments submitted at
Regulations.gov, follow the online instructions for submitting
comments. Once submitted, comments cannot be edited or removed from

I. The 2008 Ozone NAAQS Emissions Inventory and Emissions Statement
Rule Requirements

On March 12, 2008, EPA promulgated a revised 8-hour ozone NAAQS of
0.075 parts per million (ppm). See 73 FR 16436 (March 27, 2008). On
July 20, 2012, EPA designated nonattainment areas for the 2008 ozone
NAAQS (77 FR 30088, May 21, 2012, and 77 FR 34221, June 11, 2012). The
Chicago-Naperville, IL-IN-WI area was designated as a marginal
nonattainment area for the 2008 ozone NAAQS. The Indiana portion of
this ozone nonattainment area consists of Lake and Porter Counties.

A. Emissions Inventories

CAA sections 172(c)(3) and 182(a)(1), 42 U.S.C. 7502(c)(3) and
7511a(a)(1), require states to develop and submit, as SIP revisions,
comprehensive, accurate, and complete emissions inventories for all
areas designated as nonattainment for the ozone NAAQS. An emissions
inventory for ozone is an estimation of actual emissions of air
pollutants that contribute to the formation of ozone in an area. Ozone
is a gas that is formed by the reaction of Volatile Organic Compounds
(VOC) and Oxides of Nitrogen (NOX) in the atmosphere in the
presence of sunlight (VOC and NOX are referred to as ozone
precursors). Therefore, an emissions inventory for ozone covers the
emissions of VOC and NOX within an ozone nonattainment area.
VOC is emitted by many types of pollution sources, including power
plants, industrial sources, on-road and off-road mobile sources,
smaller stationary sources, collectively referred to as area sources,
and biogenic sources.\1\ NOX is primarily emitted by
combustion sources, both stationary and mobile.
---------------------------------------------------------------------------

\1\ Biogenic emissions are produced by living organisms and are
typically not included in the base year emission inventories, but
are considered in ozone modeling analyses, which must consider all
emissions in a modeled area.
---------------------------------------------------------------------------

The emissions inventory provides emissions data for a variety of
air quality planning tasks, including establishing baseline emission
levels for calculating emission reduction targets needed to attain the
NAAQS and for calculating emission reduction targets needed to meet
Reasonable Further Progress (RFP) requirements, determining emission
inputs for ozone air quality modeling analyses, and tracking emissions
over time to determine progress toward achieving air quality and
emission reduction goals. As stated above, the CAA requires the states
to submit emissions inventories for areas designated as nonattainment
for ozone.
For the 2008 ozone NAAQS, EPA has recommended that states use 2011
as a base year for the emissions estimates (78 FR 34178, 34190, June 6,
2013). However, EPA also allows states to submit base year emissions
for other years during a recent ozone standard violation period. States
are required to submit estimates of VOC and NOX emissions
for four general classes of anthropogenic sources in their emissions
inventories: Stationary point sources; area sources; on-road mobile
sources; and off-road mobile sources.

B. Emissions Statement Rules

Section 182(a)(3)(B) of the CAA requires states with ozone
nonattainment areas to submit revisions to their SIP to require the
owner or operator of each major stationary source of NOX or
VOC to provide the state with an annual statement documenting the
actual emissions of NOX and VOC from their source. Under
section 182(a)(3)(B)(ii), a state may waive the emissions statement
requirement for any class or category of stationary sources which emits
less than 25 tons per year of VOC or NOX if the state, in
its base year emissions inventory, provides an inventory of emissions
from such class or category of sources. States and EPA have generally
interpreted this waiver provision to apply to sources (without
specification of a specific source class or source category) emitting
less than 25 tons per year of VOC or NOX.
Many states adopted these emissions statement rules for the 1-hour
ozone NAAQS. For these states, EPA is accepting certifications that
their previously adopted emissions statement rules remain in place and
are adequate to meet the emissions statement rule requirement under the
2008 ozone standard.

II. Indiana's Emissions Inventory

On June 15, 2016, IDEM submitted an ozone redesignation request for
Lake and Porter Counties for the 2008 ozone NAAQS. Included in this
request was documentation of a 2011 VOC and NOX base year
emissions inventory for Lake and Porter Counties intended to meet the
emissions inventory requirement of CAA section 182(a)(1). Preliminary
monitoring data for 2016 indicates that the Chicago-Naperville, IL-IN-
WI area is violating the 2008 ozone standard with 2014-2016 data.
Therefore, EPA is not taking action on the ozone redesignation request
portion of this June 15, 2016, submittal at this time. We are, however,
proceeding with rulemaking on the base year VOC and NOX
emissions inventory portion of the submittal.
Table 1 summarizes the 2011 VOC and NOX emissions for
Lake and Porter Counties in units of tons of emissions per ozone season
\2\ day documented in Indiana's submittal.
---------------------------------------------------------------------------

\2\ The ozone season is the portion of the year in which high
ozone concentrations may be expected in a given area. For Lake and
Porter Counties, the ozone season is March through October.

Indiana estimated emissions for all source categories, except on-
road mobile sources, using annual emissions data contained in EPA's
2011 National Emissions Inventory (NEI) database. To document the
derivation of these emissions data, IDEM included EPA's ``Technical
Support Document (TSD) Preparation of Emissions Inventories for the
Version 6.2 2011 Emissions Modeling Platform'' (August 2015) in the
June 15, 2016, submittal. The Ozone NAAQS Emissions Modeling Platform
(2011v6.2) was used by EPA to collect or estimate emissions data for
the 2011 NEI.
For point sources (EGUs and non-EGUs), IDEM calculates and stores
emissions data annually in the state's Emissions Inventory Tracking
System (EMITS) and annually collects such data through Indiana's
Emissions Statement program. The point source data for 2011 were
submitted through the Emissions Inventory System (EIS) gateway to the
2011 NEI. The EPA has supplemented the point source data in the 2011
NEI using emissions data from other databases, such as the Clean Air
Markets emissions database.
The area source emissions in the 2011 NEI were developed by the
EPA, with comments provided by the states.
Non-road mobile source emissions data were developed by the EPA
using the National Mobile Inventory Model (NMIM).
On-road mobile source emissions were supplied by the Northwest
Indiana Regional Planning Commission (NIRPC) and were developed using
EPA's Motor Vehicle Emission Simulator, version 2014 (MOVES2014),
emissions model and traffic data provided by the Indiana Department of
Transportation (INDOT).
All annual emissions data were temporally allocated to ozone season
days using temporal files found in EPA's Modeling Clearinghouse, https://www3.eap.gov/ttn/chief/emch/.
It is noted that, in addition to documenting county emissions
totals, IDEM has also listed VOC and NOX emissions by Source
Classification Code (SCC) and emissions from specific major source
facilities (point sources).

III. Indiana's Emissions Statement Rule Certification

On June 15, 2016, through a separate submittal, IDEM submitted a
certification letter confirming that Indiana's existing Emissions
Reporting Rule is currently being implemented and is adequate to meet
the CAA section 182(a)(3)(B) emissions reporting requirement. IDEM
noted that the Emissions Reporting Rule, 326 Indiana Administrative
Code (IAC) 2-6, was adopted by Indiana's Air Pollution Control Board
(APCB) on December 3, 2003. This rule is part of Indiana's SIP. The
rule requires sources located in Lake and Porter Counties that emit
either NOX or VOC equal to or greater than 25 tons per year
to annually report their actual emissions to IDEM.
IDEM has certified in its June 15, 2016, letter that 326 IAC 2-6
satisfies CAA section 182(a)(3)(B) emissions reporting requirements for
Lake and Porter Counties for the 2008 ozone NAAQS. Included with the
certification letter is a copy of rule 326 IAC 2-6.

IV. EPA's Evaluation

A. Emissions Inventory

In accordance with sections 172(c)(3) and 182(a)(1) of the CAA,
Indiana's submittal contains a comprehensive, accurate, and current
inventory of actual VOC and NOX emissions for all relevant
sources in Lake and Porter Counties. The state documented the general
procedures used to estimate the ozone season day emissions for each of
the major source categories and for SCCs and point source facilities.
IDEM provided detailed model input data used to derive on-road
emissions. The documentation of the emissions estimation procedures and
data sources has been determined to be adequate.
IDEM has submitted evidence that it provided the public with an
opportunity to request a public hearing and to comment on the material
contained in the June 15, 2016, submittal. A public hearing was not
requested and IDEM received no comments on the submission. Therefore,
the state has complied with public notice and review requirements of
the CAA.
Based on the adequacy of the emissions inventories documentation
and on the evidence that the public has been given an opportunity to
comment on the emissions inventories, the base year emissions
inventories are approvable.

B. Emissions Statement Rule

EPA approved Indiana's emissions statement rule, 326 IAC 2-6, into
the Indiana SIP on March 27, 2007 (72 FR 14678), and it is currently
being implemented. The rule requires sources of VOC and NOX
in Lake and Porter Counties to annually report these emissions to the
state if the sources emit VOC or NOX equaling or exceeding
25 tons per year. In addition, it is noted that Indiana typically
reports point source emissions to the NEI with source cutoffs well
below 25 tons per year, covering VOC and NOX emissions from
sources that are not required to submit annual emissions statements.
Therefore, Indiana's rule 326 IAC 2-6 meets the requirements of CAA
section 182(a)(3)(B) and is approvable.

V. Final Action

EPA is approving the emissions inventory submitted by Indiana and
specified in Table 1 above as meeting the requirements of sections
172(c)(3) and 182(a)(1) of the CAA for Lake and Porter Counties for the
2008 ozone NAAQS. We are also approving Indiana's certification that
the state has an emissions statement rule in its SIP for VOC and
NOX stationary sources in

[[Page 16937]]

Lake and Porter Counties, in accordance with the CAA section
182(a)(3)(B).
We are publishing this action without prior proposal because we
view this as a noncontroversial amendment and anticipate no adverse
comments. However, in the proposed rules section of this Federal
Register publication, we are publishing a separate document that will
serve as the proposal to approve the state plan if relevant adverse
written comments are filed. This rule will be effective June 6, 2017
without further notice unless we receive relevant adverse written
comments by May 8, 2017. If we receive such comments, we will withdraw
this action before the effective date by publishing a subsequent
document that will withdraw the final action. All public comments
received will then be addressed in a subsequent final rule based on the
proposed action. EPA will not institute a second comment period. Any
parties interested in commenting on this action should do so at this
time. Please note that, if EPA receives adverse comment on an
amendment, paragraph, or section of this rule and if that provision may
be severed from the remainder of the rule, EPA may adopt as final those
provisions of the rule that are not the subject of an adverse comment.
If we do not receive any comments, this action will be effective June
6, 2017.

VI. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA 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).
In addition, 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 June 6, 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. Parties with objections to this direct final rule are
encouraged to file a comment in response to the parallel notice of
proposed rulemaking for this action published in the proposed rules
section of today's Federal Register, rather than file an immediate
petition for judicial review of this direct final rule, so that EPA can
withdraw this direct final rule and address the comment in the proposed
rulemaking. This action may not be challenged later in proceedings to
enforce its requirements. (See section 307(b)(2).)
