Air Approval Plan; Oklahoma; Excess Emission and Malfunction 
Reporting Requirements

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: Pursuant to the Federal Clean Air Act (CAA, the Act), the 
Environmental Protection Agency (EPA) is proposing to approve a 
revision to the Oklahoma State Implementation Plan (SIP) submitted by 
the State of Oklahoma through the Secretary of Energy & Environment on 
November 7, 2016. The revision was submitted in response to a finding 
of substantial inadequacy and SIP call published by EPA on June 12, 
2015, which included certain provisions in the Oklahoma SIP related to 
excess emissions during startup, shutdown, and malfunction (SSM) 
events. The submittal requests the removal of the provisions identified 
in the 2015 SIP call from the Oklahoma SIP. EPA is proposing to 
determine that the removal of these substantially inadequate provisions 
from the SIP will correct the deficiencies in the Oklahoma SIP 
identified in the June 12, 2015 SIP call.

DATES: Comments must be received on or before March 6, 2023.

I. Background

A. EPA's 2015 SIP Action

    On February 22, 2013, EPA issued a Federal Register proposed 
rulemaking action outlining EPA's policy at the time with respect to 
SIP provisions related to periods of SSM. EPA analyzed specific SSM SIP 
provisions and explained how

[[Page 7379]]

each one either did or did not comply with the CAA with regard to 
excess emission events.\1\ For each SIP provision that EPA determined 
to be inconsistent with the CAA, EPA proposed to find that the existing 
SIP provision was substantially inadequate to meet CAA requirements and 
thus proposed to issue a SIP call under CAA section 110(k)(5). On 
September 17, 2014, EPA issued a document supplementing and revising 
what the Agency had previously proposed on February 22, 2013, in light 
of a D.C. Circuit decision that determined the CAA precludes authority 
of EPA to create affirmative defense provisions applicable to private 
civil suits. EPA outlined its updated policy that affirmative defense 
SIP provisions are not consistent with CAA requirements. EPA proposed 
in the supplemental proposal document to apply its revised 
interpretation of the CAA to specific affirmative defense SIP 
provisions and proposed SIP calls for those provisions where 
appropriate (79 FR 55920, September 17, 2014).
---------------------------------------------------------------------------

    \1\ State Implementation Plans: Response to Petition for 
Rulemaking; Findings of Substantial Inadequacy; and SIP Calls To 
Amend Provisions Applying to Excess Emissions During Periods of 
Startup, Shutdown, and Malfunction, (78 FR 12460) Feb. 22, 2013.
---------------------------------------------------------------------------

    On June 12, 2015, pursuant to CAA section 110(k)(5), EPA finalized 
``State Implementation Plans: Response to Petition for Rulemaking; 
Restatement and Update of EPA's SSM Policy Applicable to SIPs; Findings 
of Substantial Inadequacy; and SIP Calls To Amend Provisions Applying 
to Excess Emissions During Periods of Startup, Shutdown and 
Malfunction,'' (80 FR 33839, June 12, 2015), hereafter referred to as 
the ``2015 SSM SIP Action.'' The 2015 SSM SIP Action clarified, 
restated, and updated EPA's interpretation that SSM exemption and 
affirmative defense SIP provisions are inconsistent with CAA 
requirements. The 2015 SSM SIP Action found that certain SIP provisions 
in 36 states, including Oklahoma, were substantially inadequate to meet 
CAA requirements and issued a SIP call to those states to submit SIP 
revisions to address the inadequacies. EPA established an 18-month 
deadline by which the affected states had to submit such SIP revisions. 
States were required to submit corrective revisions to their SIPs in 
response to the SIP calls by November 22, 2016. The detailed rationale 
for issuing the SIP call to Oklahoma can be found in the 2015 SSM SIP 
Action and preceding proposed actions.
    EPA issued a Memorandum in October 2020 (2020 Memorandum), which 
stated that certain provisions governing SSM periods in SIPs could be 
viewed as consistent with CAA requirements.\2\ Importantly, the 2020 
Memorandum stated that it ``did not alter in any way the determinations 
made in the 2015 SSM SIP Action that identified specific state SIP 
provisions that were substantially inadequate to meet the requirements 
of the Act.'' Accordingly, the 2020 Memorandum had no direct impact on 
the SIP call issued to Oklahoma in 2015. The 2020 Memorandum did, 
however, indicate EPA's intent at the time to review SIP calls that 
were issued in the 2015 SSM SIP Action to determine whether EPA should 
maintain, modify, or withdraw particular SIP calls through future 
agency actions.

Governing Periods of Startup, Shutdown, and Malfunctions in State 
Implementation Plans,'' from Andrew R. Wheeler, Administrator.
---------------------------------------------------------------------------

    On September 30, 2021, EPA's Deputy Administrator withdrew the 2020 
Memorandum and announced EPA's return to the policy articulated in the 
2015 SSM SIP Action (2021 Memorandum).\3\ As articulated in the 2021 
Memorandum, SIP provisions that contain exemptions or affirmative 
defense provisions are not consistent with CAA requirements and, 
therefore, generally are not approvable if contained in a SIP 
submission. This policy approach is intended to ensure that all 
populations, including overburdened communities, impacted by air 
pollution receive the full health and environmental protections 
provided by the CAA.\4\ The 2021 Memorandum also retracted the prior 
statement from the 2020 Memorandum of EPA's plans to review and 
potentially modify or withdraw particular SIP calls. That statement no 
longer reflects EPA's intent. EPA intends to implement the principles 
laid out in the 2015 SSM SIP Action as the agency takes action on SIP 
submissions, including this SIP submittal provided by Oklahoma in 
response to the 2015 SIP call.

B. Oklahoma's Subchapter 9 (OAC 252:100-9) Excess Emission and 
Malfunction Reporting Requirements

    Oklahoma Administrative Code (OAC), Title 252, Chapter 100, 
Subchapter 9 (OAC 252:100-9) Excess Emission and Malfunction Reporting 
Requirements (hereafter, Subchapter 9) was approved into the Oklahoma 
SIP on November 3, 1999 (64 FR 59629), and became federally effective 
on January 3, 2000.
    As a part of EPA's 2015 SSM SIP Action, EPA made a finding that 
certain provisions in the Oklahoma SIP are substantially inadequate to 
meet CAA requirements because they provide for discretionary exemptions 
from otherwise applicable SIP emission limitations, and thus issued a 
SIP call with respect to these provisions. The SIP-called provisions 
were OAC 252:100-9-3(a) and OAC 252:100-9-3(b) of Subchapter 9.\5\
---------------------------------------------------------------------------

    \5\ Section G. Affected States in EPA Region VI, June 12, 2015 
(80 FR 33968).
---------------------------------------------------------------------------

II. Analysis of SIP Submission

    In response to EPA's 2015 SSM SIP Action, Oklahoma submitted a SIP 
revision on November 7, 2016, requesting the removal of the SIP-called 
provisions, OAC 252:100-9-3(a) and OAC 252:100-9-3(b) of Subchapter 9. 
Although not part of the finding in the 2015 SIP call, in addition to 
OAC 252:100-9-3(a) and (b), Oklahoma decided to remove the remaining 
sections of EPA-approved Subchapter 9: OAC 252:100-9-1, OAC 252:100-9-
2, OAC 252:100-9-4, OAC 252:100-9-5, and OAC 252:100-9-6 from its 
SIP.\6\ EPA believes that removal of Subchapter 9 from the Oklahoma SIP 
will eliminate the impermissible discretionary exemptions from 
applicable emissions limits, but will not otherwise affect the adequacy 
of the remaining portions of the Oklahoma SIP. EPA concurs with this 
State action and is proposing to approve removing these provisions (OAC 
252:100-9-1, OAC 252:100-9-2, OAC 252:100-9-4, OAC 252:100-9-5, and OAC 
252:100-9-6) in addition to the substantially inadequate SIP-called 
provisions (OAC 252:100-9-3(a) and OAC 252:100-9-3(b)) from the 
Oklahoma SIP.
---------------------------------------------------------------------------

    \6\ Specifically, the remaining sections of EPA-approved 
Subchapter 9 Excess Emission and Malfunction Reporting Requirements 
are OAC 252:100-9-1 (concerning Purpose), OAC 252:100-9-2 
(concerning Definitions), OAC 252:100-9-4 (concerning Maintenance 
Procedures), OAC 252:100-9-5 (concerning Malfunctions and Releases), 
and OAC 252:100-9-6 (concerning Excesses Resulting from Engineering 
Limitations).
---------------------------------------------------------------------------

    Oklahoma's submittal also includes an analysis to demonstrate 
compliance with Section 110(l) of the Act.\7\ Removal of Subchapter 9 
in its entirety from the Oklahoma SIP is not expected to lead to any 
emissions increase and, therefore, will not affect the State's ability 
to attain or maintain state or federal standards or reasonable further 
progress. This

[[Page 7380]]

approach is consistent with the analogy presented in EPA's Example 1 at 
80 FR 33975 of the 2015 SSM SIP Action. Consequently, EPA is proposing 
to approve the removal of Subchapter 9 from the Oklahoma SIP.
---------------------------------------------------------------------------

    \7\ Pages 3-4 of the November 7, 2016 SIP submittal.
---------------------------------------------------------------------------

    We also note that Oklahoma has replaced the EPA-approved version of 
Subchapter 9 with a new State rule; however, Oklahoma has not submitted 
the new rule as a SIP revision, and it is not the subject of this 
rulemaking action. Applicable only under State law, the new Subchapter 
9 rule establishes emission reporting requirements and criteria for 
seeking mitigation of penalties for excess emission violations sought 
in State enforcement actions. These provisions do not apply to actions 
brought by EPA or citizens to enforce excess emission violations.\8\

III. Impacts on Areas of Indian Country

    Following the U.S. Supreme Court decision in McGirt v. Oklahoma, 
140 S. Ct. 2452 (2020), the Governor of the State of Oklahoma requested 
approval under Section 10211(a) of the Safe, Accountable, Flexible, 
Efficient Transportation Equity Act of 2005: A Legacy for Users, Public 
Law 109-59, 119 Stat. 1144, 1937 (August 10, 2005) (``SAFETEA''), to 
administer in certain areas of Indian country (as defined at 18 U.S.C. 
1151) the State's environmental regulatory programs that were 
previously approved by the EPA for areas outside of Indian country. The 
State's request excluded certain areas of Indian country further 
described below. In addition, the State only sought approval to the 
extent that such approval is necessary for the State to administer a 
program in light of Oklahoma Dept. of Environmental Quality v. EPA, 740 
F.3d 185 (D.C. Cir. 2014).\9\
---------------------------------------------------------------------------

    \9\ In ODEQ v. EPA, the D.C. Circuit held that under the CAA, a 
state has the authority to implement a SIP in non-reservation areas 
of Indian country in the state, where there has been no 
demonstration of tribal jurisdiction. Under the D.C. Circuit's 
decision, the CAA does not provide authority to states to implement 
SIPs in Indian reservations. ODEQ did not, however, substantively 
address the separate authority in Indian country provided 
specifically to Oklahoma under SAFETEA. That separate authority was 
not invoked until the State submitted its request under SAFETEA, and 
was not approved until EPA's decision, described in this section, on 
October 1, 2020.
---------------------------------------------------------------------------

    On October 1, 2020, the EPA approved Oklahoma's SAFETEA request to 
administer all the State's EPA-approved environmental regulatory 
programs, including the Oklahoma SIP, in the requested areas of Indian 
country. As requested by Oklahoma, the EPA's approval under SAFETEA 
does not include Indian country lands, including rights-of-way running 
through the same, that: (1) Qualify as Indian allotments, the Indian 
titles to which have not been extinguished, under 18 U.S.C. 1151(c); 
(2) are held in trust by the United States on behalf of an individual 
Indian or Tribe; or (3) are owned in fee by a Tribe, if the Tribe (a) 
acquired that fee title to such land, or an area that included such 
land, in accordance with a treaty with the United States to which such 
Tribe was a party, and (b) never allotted the land to a member or 
citizen of the Tribe (collectively ``excluded Indian country lands'').
    The EPA's approval under SAFETEA expressly provided that to the 
extent EPA's prior approvals of Oklahoma's environmental programs 
excluded Indian country, any such exclusions are superseded for the 
geographic areas of Indian country covered by the EPA's approval of 
Oklahoma's SAFETEA request.\10\ The approval also provided that future 
revisions or amendments to Oklahoma's approved environmental regulatory 
programs would extend to the covered areas of Indian country (without 
any further need for additional requests under SAFETEA).\11\
---------------------------------------------------------------------------

    \10\ EPA's prior approvals relating to Oklahoma's SIP frequently 
noted that the SIP was not approved to apply in areas of Indian 
country (consistent with the D.C. Circuit's decision in ODEQ v. EPA) 
located in the state. See, e.g., 85 FR 20178, 20180 (April 10, 
2020). Such prior expressed limitations are superseded by the EPA's 
approval of Oklahoma's SAFETEA request.
    \11\ On December 22, 2021, the EPA proposed to withdraw and 
reconsider the October 1, 2020, SAFETEA approval. See https://www.epa.gov/ok/proposed-withdrawal-and-reconsideration-and-supporting-information. The EPA expects to have further discussions 
with tribal governments and the State of Oklahoma as part of this 
reconsideration. The EPA also notes that the October 1, 2020, 
approval is the subject of a pending challenge in federal court. 
Pawnee Nation of Oklahoma v. Regan, No. 20-9635 (10th Cir.). The EPA 
may make further changes to any approval of Oklahoma's program to 
reflect the outcome of the proposed withdrawal and reconsideration 
of the October 1, 2020, SAFETEA approval.
---------------------------------------------------------------------------

    As explained above, the EPA is proposing to approve a revision to 
the Oklahoma SIP submitted by the State of Oklahoma on November 7, 
2016. More specifically, we are proposing to approve the removal of OAC 
252:100-9-1, OAC 252:100-9-2, OAC 252:100-9-3(a) and (b), OAC 252:100-
9-4, OAC 252:100-9-5, and OAC 252:100-9-6 of Subchapter 9 Excess 
Emission and Malfunction Reporting Requirements of the Oklahoma SIP. 
Consistent with the D.C. Circuit's decision in ODEQ v. EPA and with 
EPA's October 1, 2020 SAFETEA approval, if this approval is finalized 
as proposed, these SIP revisions will apply to all Indian country 
within the State of Oklahoma, other than the excluded Indian country 
lands. Because--per the State's request under SAFETEA--EPA's October 1, 
2020 approval does not displace any SIP authority previously exercised 
by the State under the CAA as interpreted in ODEQ v. EPA, the SIP will 
also apply to any Indian allotments or dependent Indian communities 
located outside of an Indian reservation over which there has been no 
demonstration of tribal authority.

IV. Proposed Action

    EPA is proposing to approve a revision to the Oklahoma SIP 
submitted by the State of Oklahoma on November 7, 2016, in response to 
EPA's SSM SIP Action, concerning excess emissions during periods of 
SSM. Specifically, we are proposing to approve the removal of OAC 
252:100-9-1, OAC 252:100-9-2, OAC 252:100-9-3(a) and (b), OAC 252:100-
9-4, OAC 252:100-9-5, and OAC 252:100-9-6 of Subchapter 9 Excess 
Emission and Malfunction Reporting Requirements of the Oklahoma SIP. We 
are proposing to approve these revisions in accordance with section 110 
of the Act. EPA is further proposing to determine that such SIP 
revision corrects the inadequacies in the Oklahoma SIP as identified in 
the 2015 SSM SIP Action. EPA is not reopening the 2015 SSM SIP Action 
and is only taking comment on whether this proposed SIP revision is 
consistent with CAA requirements and whether it addresses the 
substantial inadequacy in the provisions of the Oklahoma SIP identified 
in the 2015 SSM SIP Action.

V. Environmental Justice Considerations

    For informational purposes only, EPA is providing additional 
information regarding this proposed action and potentially impacted 
populations. EPA defines environmental justice (EJ) as ``the fair 
treatment and meaningful involvement of all people regardless of race, 
color, national origin, or income with respect to the development, 
implementation, and enforcement of environmental laws, regulations, and 
policies.'' The EPA further defines the term fair treatment to mean 
that ``no group of people should bear a disproportionate burden of 
environmental harms and risks, including those resulting from the 
negative environmental consequences of industrial, governmental, and 
commercial operations or programs and policies.'' \12\

    EPA reviewed demographic data for Oklahoma, which provides an 
assessment of individual demographic groups of the populations living 
within the State.\13\ EPA then compared this data to the national 
average for each of the demographic groups. The results of the 
demographic analysis indicate that, for populations within Oklahoma, 
the percent people who reported their race as a category other than 
White alone (not Hispanic or Latino) is higher than national average 
(63.8 percent versus 59.3 percent). The percent of population that is 
American Indian/Alaska Native alone is significantly higher than the 
national average (9.7 percent versus 1.3 percent). The percent of 
people living below the poverty level in Oklahoma is higher than the 
national average (14.3 percent versus 11.4 percent). The percent of 
people over 25 with a high school diploma in Oklahoma is similar to the 
national average (88.6 percent versus 88.5 percent), while the percent 
with a Bachelor's degree or higher is lower than the national average 
(26.1 percent versus 32.9 percent).

_____________________________________-

    Communities in close proximity to and/or downwind of industrial 
sources may be subject to disproportionate environmental impacts of 
excess emissions. Short- and/or long-term exposure to air pollution has 
been associated with a wide range of human health effects including 
increased respiratory symptoms, hospitalization for heart or lung 
diseases, and even premature death. Excess emissions during startups, 
shutdowns, and malfunctions exceed applicable emission limitations and 
can be considerably higher than emissions under normal steady-state 
operations. As to all population groups within the State of Oklahoma, 
as explained below, we believe that this proposed action will be 
beneficial and may reduce impacts. As discussed earlier in this notice, 
this rulemaking, if finalized as proposed, would result in the removal 
of the provisions in the Oklahoma SIP applicable to all areas in the 
State that provide sources emitting pollutants in excess of otherwise 
allowable amounts with the opportunity to seek executive director 
discretion for violations involving excess emissions during startup, 
shutdown, and malfunctions. Federal removal of such impermissible 
executive director discretion provisions from the SIP is necessary to 
preserve the enforcement structure of the CAA, to preserve the 
jurisdiction of courts to adjudicate questions of liability and 
remedies in judicial enforcement actions and to preserve the potential 
for enforcement by the EPA and other parties under the citizen suit 
provision as an effective deterrent to violations. If finalized as 
proposed, this action is intended to ensure that overburdened 
communities and affected populations across the State and downwind 
areas receive the full human health and environmental protection 
provided by the CAA. There is nothing in the record which indicates 
that this proposed action, if finalized, would have disproportionately 
high or adverse human health or environmental effects on communities 
with environmental justice concerns.

VI. Incorporation by Reference

    In this action, we are proposing to include in a final rule 
regulatory text that includes incorporation by reference. In accordance 
with the requirements of 1 CFR 51.5, we are proposing to remove the 
Oklahoma regulations described in the Proposed Action section above. 
The EPA has made, and will continue to make, these documents generally 
available electronically through www.regulations.gov and in hard copy 
at the EPA Region 6 office.

VII. Statutory and Executive Order Reviews

    Under the Act, 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 Act. Accordingly, this 
action merely proposes to approve 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 Order 
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 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).
    This proposed approval of a revision to the Oklahoma SIP removing 
provisions providing discretionary exemptions from excess emission 
violations as discussed more fully elsewhere in this document will 
apply, if finalized as proposed, to certain areas of Indian country as 
discussed in the preamble, and therefore has tribal implications as 
specified in E.O. 13175 (65 FR 67249, November 9, 2000). However, this 
action will neither impose substantial direct compliance costs on 
federally recognized tribal governments, nor preempt tribal law. This 
action will not impose substantial direct compliance costs on federally 
recognized tribal governments because no actions will be required of 
tribal governments. This action will also not preempt tribal law as no 
Oklahoma tribe implements a regulatory program under the CAA, and thus 
does not have applicable or related tribal laws. Consistent with the 
EPA Policy on Consultation and Coordination with Indian Tribes (May 4, 
2011), the EPA has offered consultation to tribal governments that may 
be affected by this action.
