Air Plan Approval; Ohio; Prevention of Significant Deterioration 
Greenhouse Gas Tailoring Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve, under the Clean Air Act (CAA), a revision to Ohio's State 
Implementation Plan (SIP), submitted by the Ohio Environmental 
Protection Agency (OEPA) on March 30, 2011 and amended on August 22, 
2019. The proposed SIP revision modifies Ohio's Prevention of 
Significant Deterioration (PSD) program to establish emission 
thresholds for determining when stationary source projects are 
potentially subject to Ohio's PSD permitting requirements for 
greenhouse gas (GHG) emissions. Consistent with Ohio's August 22, 2019, 
request, EPA is not acting on the portion of Ohio's submittal that 
would allow for automatic rescission of certain rule provisions and 
permit terms and conditions if certain triggering events occurred 
(i.e., the auto-rescission clause).

I. Background for Our Proposed Action

    This section briefly summarizes EPA's GHG-related actions that 
provide the background for this proposed action. More detailed 
discussion of the background is found in the preambles for those 
actions. In particular, background information is contained in what we 
call the GHG PSD SIP Narrowing Rule,\1\ and in the preambles to the 
actions it cites.

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

A. GHG-Related Actions

    EPA has undertaken a series of actions pertaining to the regulation 
of GHGs that establish the overall framework for this proposed action 
on the Ohio SIP. Four of these actions include, as they are commonly 
called, the ``Endangerment Finding'' and the ``Cause or Contribute 
Finding,'' which EPA issued in a single final action; \2\ the ``Johnson 
Memo Reconsideration;'' \3\ the ``Light-Duty Vehicle Rule (LDVR);'' \4\ 
and the ``Tailoring Rule.'' \5\ Taken together and in conjunction with 
the CAA, these actions established

[[Page 63602]]

regulatory requirements for GHGs emitted from new motor vehicles and 
new motor vehicle engines; determined that such regulations, when they 
took effect on January 2, 2011, subjected GHGs emitted from stationary 
sources to PSD requirements; and limited the applicability of PSD 
requirements to GHG sources on a phased-in basis. EPA took this 
limiting action in the GHG Tailoring Rule (Tailoring Rule), which more 
specifically established appropriate GHG emission thresholds for 
determining the applicability of PSD requirements to GHG-emitting 
sources.
---------------------------------------------------------------------------

    \2\ ``Endangerment and Cause or Contribute Findings for 
Greenhouse Gases Under Section 202(a)of the Clean Air Act.'' 74 FR 
66496 (December 15, 2009).

Pollutants Covered by Clean Air Act Permitting Programs.'' 75 FR

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

    PSD is implemented through the SIP system, and so in December 2010, 
EPA promulgated several rules to implement the new GHG PSD SIP program. 
Recognizing that some states had approved SIP PSD programs that did not 
apply PSD to GHGs, EPA issued a SIP call and, for some of these states, 
a Federal Implementation Plan (FIP).\6\ States without approved SIP 
programs must implement the Federal PSD requirements in 40 Code of 
Federal Regulations (CFR) 52.21. Recognizing that other states had 
approved SIP PSD programs that do apply PSD to GHGs, but that do so for 
sources that emit as little as 100 or 250 tons per year (tpy) of GHG, 
and that do not limit PSD applicability to GHGs to the higher 
thresholds in the Tailoring Rule, EPA issued the GHG PSD SIP Narrowing 
Rule. Under that rule, EPA withdrew its approval of the affected SIPs 
to the extent those SIPs covered GHG-emitting sources below the 
Tailoring Rule thresholds. EPA based its action primarily on the 
``error correction'' provisions of CAA section 110(k)(6).
---------------------------------------------------------------------------

    \6\ Specifically, by action dated December 13, 2010, EPA 
finalized a ``SIP Call'' that would require those states with SIPs 
that have approved PSD programs but do not authorize PSD permitting 
for GHGs to submit a SIP revision providing such authority. See 
``Action to Ensure Authority to Issue Permits Under the Prevention 
of Significant Deterioration Program to Sources of Greenhouse Gas 
Emissions: Finding of Substantial Inadequacy and SIP Call,'' 75 FR 
77698 (Dec. 13, 2010). EPA has made findings of failure to submit 
that would apply in any state unable to submit the required SIP 
revision by its deadline, and finalizing FIPs for such states. See, 
e.g., ``Action To Ensure Authority To Issue Permits Under the 
Prevention of Significant Deterioration Program to Sources of 
Greenhouse Gas Emissions: Findings of Failure To Submit State 
Implementation Plan Revisions Required for Greenhouse Gases,'' 75 FR 
81874 (December 29, 2010); ``Action To Ensure Authority To Issue 
Permits Under the Prevention of Significant Deterioration Program to 
Sources of Greenhouse Gas Emissions: Federal Implementation Plan, 
``75 FR 82246 (December 30, 2010).
---------------------------------------------------------------------------

    As of January 2, 2011, GHG emissions were, for the first time, 
covered by the title V operating permit and PSD programs via the 
Tailoring Rule. In Step 1 of the Tailoring Rule (Step 1), EPA limited 
application of title V and PSD requirements to sources and 
modifications of GHG emissions, but only if they were subject to PSD or 
title V ``anyway'' due to their emissions of pollutants other than 
GHGs. These sources and modifications covered under Step 1 are commonly 
referred to as ``anyway sources'' and ``anyway modifications'', 
respectively.
    In Step 2 of the Tailoring Rule (Step 2), which applied as of July 
1, 2011, the PSD and title V requirements extended beyond the sources 
and modifications covered under Step 1 to apply to sources that were 
classified as major sources based solely on their GHG emissions or 
potential to emit GHGs. Step 2 also applied PSD permitting requirements 
to modifications of otherwise major sources that would increase only 
GHG emissions above the level in the Federal PSD regulations. EPA 
generally described the sources and modifications covered by PSD under 
Step 2 of the Tailoring Rule as ``Step 2 sources and modifications'' or 
``GHG only sources and modifications.''
    In accordance with the phase-in process of the Tailoring Rule, EPA 
published Step 3 of the Tailoring Rule on July 12, 2012. See 77 FR 
41051. In this rule, EPA decided against further phase-in of the PSD 
and title V requirements for sources emitting lower levels of GHG 
emissions, thus the GHG thresholds remained the same as established in 
Steps 1 and 2 of the Tailoring Rule.
    Federal courts have resolved several challenges to the Tailoring 
Rule and other EPA actions regarding GHGs. On June 26, 2012, the United 
States Court of Appeals for the District of Columbia Circuit (D.C. 
Circuit) upheld the Endangerment Finding, LDVR, Tailoring Rule, and 
other actions pertinent to the regulation of GHGs under the PSD and 
title V programs. After an appeal of this case, on June 23, 2014, the 
U.S. Supreme Court addressed the application of stationary source 
permitting requirements to GHG emissions in Utility Air Regulatory 
Group (UARG) v. EPA, 134 S. Ct. 2427 (2014). The Supreme Court upheld 
EPA's regulation of GHG Step 1 or ``anyway'' sources, but held that EPA 
may not treat GHGs as air pollutants for the purpose of determining 
whether a source is a major source or is undergoing a major 
modification and thus require the source to obtain a PSD or title V 
permit. Therefore, the Court invalidated the PSD and title V permitting 
requirements for Step 2 sources and modifications.
    In accordance with the Supreme Court's decision, on April 10, 2015, 
the D.C. Circuit issued an Amended Judgment \7\ vacating the 
regulations that implemented Step 2 of the Tailoring Rule, but not the 
regulations that implement Step 1 of the Tailoring Rule. The 2015 
Amended Judgment specifically vacated the EPA regulations under review 
(including 40 CFR 51.166(b)(48)(v) and 40 CFR 52.21(b)(49)(v)) ``to the 
extent they require a stationary source to obtain a PSD permit if 
greenhouse gases are the only pollutant (i) that the source emits or 
has the potential to emit above the applicable major source thresholds, 
or (ii) for which there is a significant emissions increase from a 
modification.'' Id. at 7-8.
---------------------------------------------------------------------------

    \7\ See Coalition for Responsible Regulation, Inc. v. EPA, 606 
Fed. Appx. 6, 7 (D.C. Cir. 2015).
---------------------------------------------------------------------------

    In a subsequent rulemaking, on August 19, 2015, EPA removed from 
the CFR several provisions of the PSD and title V permitting 
regulations that were originally promulgated as part of the Tailoring 
Rule. See ``Prevention of Significant Deterioration and title V 
Permitting for Greenhouse Gases: Removal of Certain Vacated Elements'' 
(80 FR 50199, August 19, 2015). This ``good cause'' final rule removed 
from the Federal regulations the portions of the PSD permitting 
provisions for Step 2 sources that were vacated by the D.C. Circuit 
(i.e., 40 CFR 51.166(b)(48)(v) and 52.21(b)(49)(v). EPA therefore no 
longer has the authority to conduct PSD permitting for Step 2 sources. 
On October 3, 2016, EPA proposed revisions to the PSD permitting 
regulations applicable to GHGs to address the GHG applicability 
threshold for PSD in order to fully conform with the 2014 UARG decision 
and the 2015 Amended Judgment, but those revisions have not been 
finalized. See 81 FR 68110.

B. Ohio's Actions

    The Tailoring Rule requested all states to submit a letter to EPA, 
by August 2, 2010, explaining how the state intended to implement the 
GHG PSD and title V permitting requirements and whether it had 
authority to implement those requirements. 75 FR 31514 (June 3, 2010). 
On July 26, 2010, Ohio provided a letter to EPA confirming that the 
state has the authority to regulate GHGs in its PSD program. The letter 
provided that Ohio intended to apply the meaning of the term ``subject 
to regulation'' that EPA established in the Tailoring Rule. The letter 
also confirmed Ohio's intent to amend its air quality rules for the PSD 
program for GHGs to match the thresholds set in the Tailoring Rule. See

[[Page 63603]]

the docket for this proposed rulemaking for a copy of Ohio's letter.
    In the SIP Narrowing Rule, 75 FR 82536 (December 30, 2010), EPA 
withdrew its approval of certain provisions of Ohio's SIP, among other 
SIPs, to the extent that those provisions applied PSD permitting 
requirements to GHG emissions from sources emitting at levels below 
those set in the Tailoring Rule.\8\ As a result, Ohio's current SIP 
provides the state with authority to regulate GHGs but only at and 
above the Tailoring Rule thresholds; and requires new and modified 
sources to receive a PSD permit based on GHG emissions only if they 
emit at or above the Tailoring Rule thresholds.
---------------------------------------------------------------------------

    \8\ ``Limitation of Approval of Prevention of Significant 
Deterioration Provisions Concerning Greenhouse Gas Emitting-Sources 
in State Implementation Plans; Final Rule.'' 75 FR 82536 December 
30, 2010).
---------------------------------------------------------------------------

    Ohio's proposal to revise its SIP so as to limit PSD applicability 
to the higher GHG emissions thresholds in the Tailoring Rule is 
consistent with CAA section 110(a)(2)(E)(i), which requires states to 
provide necessary assurances that they have adequate funding and 
personnel to implement their SIPs. In the Tailoring Rule, EPA 
established higher thresholds for PSD applicability to GHG-emitting 
sources on grounds that the states generally did not have adequate 
resources to apply PSD to GHG-emitting sources below the Tailoring Rule 
thresholds,\9\ and no state, including Ohio, asserted that it did have 
adequate resources to do so.\10\
---------------------------------------------------------------------------

    \9\ Tailoring Rule, 75 FR 31517.
    \10\ PSD SIP Narrowing Rule, 75 FR 82540.
---------------------------------------------------------------------------

    In the SIP Narrowing Rule, EPA found that the affected states, 
including Ohio, had a flaw in their SIPs at the time they submitted 
their PSD programs, which was that the applicability of the PSD 
programs was potentially broader than the resources available to them 
under their SIP.\11\ Accordingly, for each affected state, including 
Ohio, EPA concluded, under CAA section 110(k)(6), that EPA's action in 
approving the SIP was in error, and EPA rescinded its approval to the 
extent the PSD program applies to GHG-emitting sources below the 
Tailoring Rule thresholds.\12\ EPA recommended that states adopt a SIP 
revision to incorporate the Tailoring Rule thresholds, thereby (i) 
assuring that under state law, only sources at or above the Tailoring 
Rule thresholds would be subject to PSD; and (ii) avoiding confusion 
under the federally-approved SIP by clarifying that the SIP only 
applies to sources at or above the Tailoring Rule thresholds.\13\ Ohio 
revised its PSD and title V rules by creating Ohio Administrative Code 
(OAC) rules 3745-31-34 and 3745-77-11, respectively (Ohio's GHG rules) 
to ensure that its authority to implement GHG permitting requirements 
under the PSD and title V programs is consistent with the authority 
authorized by EPA in the Tailoring Rule. Ohio's rule revisions also 
incorporated the GHG PSD applicability thresholds that EPA established 
in the Tailoring Rule. Approval of Ohio's SIP revision would resolve a 
flaw in the SIP as addressed by the SIP Narrowing Rule.

II. EPA's Analysis of the State's Submittal

    The regulatory revisions that OEPA submitted for approval on March 
30, 2011, establish thresholds for determining which stationary sources 
and modifications become subject to permitting requirements for GHG 
emissions under OEPA's PSD program. Specifically, the submittal 
includes proposed changes to Ohio's PSD regulations and requests that 
EPA approve and incorporate into Ohio's federally-approved SIP OAC rule 
3745-31-34, that Ohio adopted on March 21, 2011. Upon approval, this 
revision to Ohio's SIP will put in place the GHG emission thresholds 
for PSD applicability set forth in EPA's Tailoring Rule which will 
clarify the applicable GHG thresholds in the Ohio SIP.
    Ohio is currently a SIP-approved state for the PSD program and has 
previously incorporated some elements of EPA's 2002 New Source Review 
(NSR) reform revisions, 67 FR 80186 (December 31, 2002) for PSD into 
its SIP, 75 FR 8496 (February 25, 2010). In a letter provided to EPA on 
July 26, 2010, Ohio notified EPA of its interpretation that the state 
currently has the authority to regulate GHGs under its PSD regulations. 
Ohio's PSD SIP, which EPA approved prior to the promulgation of the 
Tailoring Rule, applies to major stationary sources (having the 
potential to emit at least 100 tpy or 250 tpy or more of a regulated 
NSR pollutant, depending on the type of source) or modifications 
undertaken in areas designated attainment or unclassifiable with 
respect to the National Ambient Air Quality Standards.
    On August 22, 2019, Ohio sent a letter to EPA requesting that EPA 
not act on OAC 3745-31-34(C) and (D) as well as OAC 3745-77-11, but to 
move forward with the approval of the remainder of OAC 3745-31-34 (OAC 
3745-31-34(A),(B),(E),(F) and (G)), thus amending Ohio's March 30, 2011 
SIP submittal. OAC 3745-31-34(C) and (D) would allow for automatic 
rescission of certain GHG rule provisions and permit terms and 
conditions if certain triggering events occurred. Such provisions are 
commonly referred to as ``auto-rescission'' provisions or clauses. 
Consistent with Ohio's request, EPA is not acting on the auto-
rescission provisions in this proposed approval. Per Ohio's request, 
EPA is also not acting on OAC 3745-77-11, Ohio's GHG title V rule.
    The Ohio rules at OAC 3745-31-34(A) and (B) both include the 
100,000 tpy carbon dioxide equivalent (CO2e) Step 2 source threshold 
which EPA no longer uses or enforces per the 2014 UARG decision and 
2015 Amended Judgment. EPA proposes to approve OAC 3745-31-34(A) and 
(B) even though they include the outdated 100,000 tpy CO2e Step 2 
threshold because those rules no longer authorize the regulation of 
Step 2 sources. Paragraph OAC 3745-31-34(A) requires permits for new 
major stationary sources that will emit or have the potential to emit 
100,000 tpy or more of CO2e, and for modifications of existing 
stationary sources that will result in a net emissions increase of 
75,000 tpy or more of CO2e, as provided in the Ohio GHG rule and ``only 
to the extent required in 40 CFR Section 151.166.'' EPA interprets the 
phrase ``and only to the extent required in 40 CFR Section 51.166'' in 
Ohio's rule to mean that Ohio will only regulate GHGs to the extent 
required in 40 CFR 51.166 (the Federal requirements governing PSD 
provisions in SIPs). Therefore, Ohio will regulate the Step 1 sources 
(75,000 tpy CO2e threshold) and not the Step 2 sources (100,000 tpy 
threshold) as provided in 40 CFR 51.166. EPA notes that Ohio's August 
26, 2014 guidance document titled ``July 2014 GHG Air Pollution 
Permitting Change, Engineering Guide #85'' describes how the UARG 
decision affects Ohio's GHG permitting program and how Ohio will no 
longer require PSD or title V for Step 2 sources in response to the 
UARG decision. Ohio's guidance document says Ohio will continue to 
require new or modified Step 1 sources to apply Best Available Control 
Technology (BACT) for GHGs and will continue to use the 75,000 tpy CO2e 
threshold to determine if the permits need to include BACT for GHGs 
until such time as EPA issues a revised threshold. Ohio's guidance 
document also explains that OAC 3745-31-34 will be implemented in line 
with the UARG decision and EPA's subsequent regulatory revisions.

[[Page 63604]]

    For the above reasons, EPA finds that Ohio is properly regulating 
GHGs in accordance with the 2014 UARG decision and 2015 Amended 
Judgement. Although OAC 3745-31-34(A) and (B) contain the 100,000 CO2e 
tpy Step 2 threshold which the UARG decision says cannot be enforced, 
EPA is proposing to approve those rules because Ohio is not regulating 
the Step 2 sources, and is only regulating the Step 1 sources.

III. What action is EPA taking?

    EPA is proposing to approve Ohio's March 30, 2011, SIP submittal, 
as amended on August 22, 2019, relating to PSD requirements for GHG-
emitting sources in OAC 3745-31-34. Specifically, Ohio's proposed SIP 
revision would establish appropriate emissions thresholds for 
determining PSD applicability for new and modified GHG-emitting sources 
in accordance with EPA's Tailoring Rule and the 2014 UARG decision. Per 
Ohio's August 22, 2019, amended SIP request, EPA is not acting on the 
OAC 3745-31-34(C) and (D) auto-rescission clause or OAC 3745-77-11, 
which is Ohio's GHG title V rule.
    If EPA does approve Ohio's changes to its air quality regulations 
to incorporate the appropriate thresholds for GHG permitting 
applicability into Ohio's SIP, then 40 CFR 52.1873(b), as included in 
EPA's SIP Narrowing Rule, which codifies EPA's limiting its approval of 
Ohio's PSD SIP to not cover the applicability of PSD to GHG-emitting 
sources below the Tailoring Rule thresholds, is no longer necessary. In 
this proposed action, EPA is proposing to amend 40 CFR 52.1873(b) to 
remove this unnecessary regulatory language.

IV. Incorporation by Reference

    In this rule, EPA is proposing to include in a final EPA rule 
regulatory text that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, EPA is proposing to incorporate by 
reference Ohio OAC 3745-31-34(A), (B), (E), (F) and (G) effective on 
March 31, 2011. EPA has made, and will continue to make, these 
documents generally available through www.regulations.gov and at the 
EPA Region 5 Office (please contact the person identified in the FOR 
FURTHER INFORMATION CONTACT section of this preamble for more 
information).

V. 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);
     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 application of those requirements would be inconsistent 
with the Clean Air Act; 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).
