Air Plan Approval; Missouri; Revisions to Cross-State Air 
Pollution Rule Annual Trading Program and Rescission of Clean Air 
Interstate Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing 
approval of revisions to the State Implementation Plan (SIP) submitted 
on January 15, 2019, and two revisions on March 7, 2019, by the State 
of Missouri. The January 15, 2019, revision requests EPA remove from 
the Missouri Code of State Regulations (CSR), the regulations that 
established trading programs under the Clean Air Interstate Rule 
(CAIR). The EPA is proposing to act only on the revisions to the annual 
nitrogen oxides (NOX) and sulfur dioxide (SO2) 
trading program. The EPA will act on the revisions to the seasonal 
NOX trading program in a separate action. The March 7, 2019, 
submissions revise Missouri's regulations related to the Cross-State 
Air Pollution (CSAPR) Annual Trading Program for SO2 and 
NOX, and for ozone season NOX. Approval of these 
revisions will not impact air quality and ensures Federal 
enforceability of the State's rules. The EPA is proposing to approve 
these SIP revisions in accordance with the requirements of the Clean 
Air Act (CAA).

DATES: Comments must be received on or before August 29, 2019.

ADDRESSES: You may send comments, identified by Docket ID No. EPA-R07-
OAR-2019-0337 to https://www.regulations.gov. Follow the online

II. What is being addressed in this document?

    The EPA is proposing to approve revisions to the Missouri State 
Implementation Plan (SIP) that were submitted to EPA on January 15, 
2019, and March 7, 2019.
    The January 15, 2019, submission revises Missouri's regulations, 
title 10 Code of State Regulations (10 CSR) 10-6.362 and 10-6.366 \1\ 
by rescinding and removing these rules. The EPA-administered trading 
programs under CAIR were discontinued on December 31, 2014, upon the 
implementation of the Cross-State Air Pollution Rule

[[Page 36860]]

(CSAPR), which was promulgated by the EPA to replace CAIR. CSAPR 
established Federal trading programs for sources in multiple states, 
including Missouri, that replace the CAIR state and Federal trading 
programs.
---------------------------------------------------------------------------

    \1\ The January 15, 2019, submission also contained a revision 
to 10 CSR 10-6.364. EPA is not proposing to act on that portion of 
the submission in this action. EPA will address this portion of the 
submission in a separate action.
---------------------------------------------------------------------------

    Missouri submitted two revisions on March 7, 2019. The submissions 
revise Missouri's SIP to remove unnecessary use of restrictive 
language, update incorporations by reference, add definitions specific 
to the rule, and fully adopt the CSAPR Annual Trading Program for both 
SO2 and NOX into the Missouri SIP. The revisions 
amend Missouri's regulations, 10 CSR 10-6.372, ``Cross-State Air 
Pollution Rule Annual NOX Trading Allowance Allocations'', 
10 CSR 10-6.374, ``Cross-State Air Pollution Rule Ozone Season 
NOX Trading Allowance Allocations'', and 10 CSR 10-6.376, 
``Cross-State Air Pollution Rule Annual SO2 Trading 
Allowance Allocations,'' which give Missouri authority for the CSAPR 
Annual Trading Programs for NOX and SO2, and 
ozone season NOX Trading Program, and provides a process to 
allocate allowances to affected units in Missouri for compliance with 
the NOX and SO2 CSAPR Annual and ozone season 
NOX Trading Programs.

III. Background

    In 2005, the EPA promulgated CAIR (70 FR 25162, May 12, 2005) to 
address transported emissions that significantly contributed to 
downwind states' nonattainment and interfered with maintenance of the 
1997 ozone and fine particulate matter (PM2.5) National 
Ambient Air Quality Standards (NAAQS). CAIR required 28 states, 
including Missouri, to revise their SIPs to reduce emissions of 
NOX and SO2, precursors to the formation of 
ambient ozone and PM2.5. Under CAIR, the EPA provided model 
state rules for separate cap-and-trade programs for annual 
NOX, ozone season NOX, and annual SO2. 
The annual NOX and annual SO2 trading programs 
were designed to address transported PM2.5 pollution, while 
the ozone season NOX trading program was designed to address 
transported ozone pollution. The EPA also promulgated CAIR Federal 
Implementation Plans (FIPs) with CAIR Federal trading programs that 
would address each state's CAIR requirements in the event that a CAIR 
SIP for the state was not submitted or approved (71 FR 25328, April 28, 
2006). Generally, both the model state rules and the Federal trading 
program rules applied only to electric generating units (EGUs), but in 
the case of the model state rule and Federal trading program for ozone 
season NOX emissions, each state had the option to submit a 
CAIR SIP revision that expanded applicability to include certain non-
EGUs[thinsp]\2\ that formerly participated in the NOX Budget 
Trading Program under the NOX SIP Call.\3\ Missouri 
submitted, and the EPA approved, a CAIR SIP revision based on the model 
state rules establishing CAIR state trading programs for annual 
SO2, annual NOX, and ozone season NOX 
emissions, with certain non-EGUs included in the state's CAIR ozone 
season NOX trading program. See 72 FR 71073 (December 14, 
2007).
---------------------------------------------------------------------------

    \2\ These non-EGUs are generally defined in the NOX 
SIP Call as stationary, fossil fuel-fired boilers, combustion 
turbines, or combined cycle systems with a maximum design heat input 
greater than 250 million British thermal units per hour (MMBtu/hr).
    \3\ In October 1998, EPA finalized the ``Finding of Significant 
Contribution and Rulemaking for Certain States in the Ozone 
Transport Assessment Group Region for Purposes of Reducing Regional 
Transport of ``Ozone''--commonly called the NOX SIP Call. 
See 63 FR 57356 (October 27, 1998).
---------------------------------------------------------------------------

    The United States Court of Appeals for the District of Columbia 
Circuit (D.C. Circuit) initially vacated CAIR in 2008, but ultimately 
remanded the rule to EPA without vacatur to preserve the environmental 
benefits provided by CAIR. North Carolina v. EPA, 531 F.3d 896, 
modified, 550 F.3d 1176 (2008). The ruling allowed CAIR to remain in 
effect temporarily until a replacement rule consistent with the court's 
opinion was developed. While the EPA worked on developing a replacement 
rule, the CAIR program continued as planned with the NOX 
annual and ozone season programs beginning in 2009 and the 
SO2 annual program beginning in 2010.
    On August 8, 2011 (76 FR 48208), acting on the D.C. Circuit's 
remand, the EPA promulgated CSAPR to replace CAIR in order to address 
the interstate transport of emissions contributing to nonattainment and 
interfering with maintenance of the two air quality standards covered 
by CAIR as well as the 2006 PM2.5 NAAQS. CSAPR required EGUs 
in affected states, including Missouri, to participate in Federal 
trading programs to reduce annual SO2, annual 
NOX, and/or ozone season NOX emissions. The rule 
also contained provisions that would sunset CAIR-related obligations on 
a schedule coordinated with the implementation of the CSAPR compliance 
requirements. CSAPR was intended to become effective January 1, 2012; 
however, the timing of CSAPR's implementation was impacted by a number 
of court actions.
    Numerous parties filed petitions for review of CSAPR in the D.C. 
Circuit, and on December 30, 2011, the D.C. Circuit stayed CSAPR prior 
to its implementation and ordered the EPA to continue administering 
CAIR on an interim basis. On August 21, 2012, the D.C. Circuit issued 
its ruling, vacating and remanding CSAPR to the EPA and ordering 
continued implementation of CAIR. EME Homer City Generation, L.P. v. 
EPA, 696 F.3d 7, 38 (D.C. Cir. 2012). The D.C. Circuit's vacatur of 
CSAPR was reversed by the United States Supreme Court on April 29, 
2014, and the case was remanded to the D.C. Circuit to resolve 
remaining issues in accordance with the Supreme Court's ruling. EPA v. 
EME Homer City Generation, L.P., 134 S. Ct. 1584 (2014). On remand, the 
D.C. Circuit affirmed CSAPR in most respects but remanded certain state 
emissions budgets. EME Homer City Generation, L.P. v. EPA (EME Homer 
City II), 795 F.3d 118, 138 (D.C. Cir. 2015).
    Throughout the initial round of D.C. Circuit proceedings and the 
ensuing Supreme Court proceedings, the stay on CSAPR remained in place, 
and the EPA continued to implement CAIR. Following the April 2014 
Supreme Court decision, the EPA filed a motion asking the D.C. Circuit 
to lift the stay in order to allow CSAPR to replace CAIR in an 
equitable and orderly manner while further D.C. Circuit proceedings 
were held to resolve remaining claims from petitioners. Additionally, 
the EPA's motion requested delay, by three years, of all CSAPR 
compliance deadlines that had not passed as of the approval date of the 
stay. On October 23, 2014, the D.C. Circuit granted EPA's request, and 
on December 3, 2014 (79 FR 71663), in an interim final rule, the EPA 
set the updated effective date of CSAPR as January 1, 2015 and delayed 
the implementation of CSAPR Phase I to 2015 and CSAPR Phase 2 to 2017. 
In accordance with the interim final rule, the EPA stopped 
administering the CAIR state and Federal trading programs with respect 
to emissions occurring after December 31, 2014, and the EPA began 
implementing CSAPR on January 1, 2015.\4\
---------------------------------------------------------------------------

    \4\ EPA solicited comment on the interim final rule and 
subsequently issued a final rule affirming the amended compliance 
schedule after consideration of comments received. 81 FR 13275 
(March 14, 2016).
---------------------------------------------------------------------------

    In October 2016, the EPA promulgated the CSAPR Update (81 FR 74504, 
October 26, 2016) to address interstate transport of ozone pollution 
with respect to the 2008 ozone NAAQS and issued FIPs that established 
or updated ozone season NOX budgets for 22 states, including 
Missouri. Starting in January 2017, the CSAPR update budgets were 
implemented via modifications to the CSAPR NOX ozone season 
allowance trading program that

[[Page 36861]]

was established under the original CSAPR.
    As noted above, starting in January 2015, the CSAPR Federal trading 
programs for annual NOX, ozone season NOX, and 
annual SO2 were applicable in Missouri. Thus, since January 
1, 2015, the EPA has not administered the CAIR state trading programs 
for annual NOX, ozone season NOX, or annual 
SO2 emissions established by the Missouri regulations.
    On January 15, 2019, the State of Missouri, through the Missouri 
Department of Natural Resources (MoDNR), formally submitted a SIP 
revision that requests removal from its SIP of Missouri Code of State 
Regulations including 10 CSR 10-6.362 Clean Air Interstate Rule 
NOX Annual Trading Program; 10 CSR 10-6.364 Clean Air 
Interstate Rule NOX Ozone Season Trading Program; and 10 CSR 
10-6.366 Clean Air Interstate Rule SO2 Annual Trading 
Program (which implemented the CAIR annual NOX, ozone season 
NOX, and annual SO2 trading programs in 
Missouri.\5\
---------------------------------------------------------------------------

    \5\ The EPA is not proposing to act on the requested revisions 
to 10 CSR 10-6.364 and will act on that submission in a separate 
action.
---------------------------------------------------------------------------

IV. What part 52 revision is the EPA proposing to approve?

    MoDNR's January 15, 2019, SIP revision requests the removal of 
regulations from the Missouri SIP under 10 CSR 10-6.362 Clean Air 
Interstate Rule Annual NOX Trading Program, 10 CSR 10-6.364 
Clean Air Interstate Rule Seasonal NOX Trading Program, and 
10 CSR 10-6.366 Clean Air Interstate Rule SO2 Trading 
Program, which implemented the state's CAIR annual NOX, 
seasonal NOX, and SO2 trading programs. The EPA 
has not administered the trading programs established by these 
regulations since January 1, 2015, when the CSAPR trading programs 
replaced the CAIR programs, and the state CAIR regulations have been 
repealed in their entirety from the Missouri Code of State Regulations. 
The amendments removing these regulations were adopted by the State Air 
Conservation Commission on September 27, 2018.
    As noted previously, the CAIR annual NOX, seasonal 
NOX, and SO2 trading programs addressed 
interstate transport of emissions under the 1997 PM2.5 NAAQS 
and the 1997 ozone NAAQS. The D.C. Circuit remanded CAIR to the EPA for 
replacement, and in response the EPA promulgated CSAPR which, among 
other things, fully addresses Missouri's interstate transport 
obligation under the 1997 PM2.5 NAAQS. (76 FR 48208 at 76 FR 
48210, August 8, 2011). The EPA stopped administering the CAIR trading 
programs after 2014 and instead began implementing the CSAPR trading 
programs in 2015.
    Therefore 10-6.362 and 10-6.366 do not play a role in addressing 
the transport obligations that the state initially adopted the rules to 
address: The CAIR trading programs are no longer being administered; 
the state's transport obligation under the 1997 PM2.5 NAAQS 
is now being addressed by the CSAPR trading programs for annual 
NOX and SO2.
    Missouri's CAIR trading programs for annual NOX and 
SO2 were adopted only to address Missouri's transport 
obligation under the 1997 PM2.5 NAAQS, one of the two NAAQS 
underlying the EPA's CAIR rules.
    In summary, Missouri's CAIR rules at 10 CSR 10-6.362 Clean Air 
Interstate Rule Annual NOX Trading Program, and 10 CSR 10-
6.366 Clean Air Interstate Rule SO2 Trading Program no 
longer play any role in addressing the transport obligations that the 
rules were adopted to address. The EPA therefore finds Missouri's 
January 15, 2019, SIP revision requesting removal of these CAIR rules 
from the SIP approvable in accordance with section 110 of the CAA. The 
public comments received on the NPR are discussed in section III of 
this proposed rulemaking notice.
    The EPA is also proposing to approve Missouri's revisions to 10 CSR 
10-6.372, 10 CSR 10-6.374, and 10 CSR 10-6.376. The proposed revisions 
to 10-6.372 give Missouri responsibility for the CSAPR NOX 
Annual Trading Program by incorporating by reference 40 CFR 97.404 
through 40 CFR 97.428 into the Missouri SIP. The monitoring and 
recordkeeping provisions of the CSAPR NOX Annual Trading 
Program, 40 CFR 97.430 through 40 CFR 97.435 are incorporated by 
reference into 10-6.372.
    Missouri has also removed the unnecessary use of restrictive 
language including the removal of the word ``required'' in sections 10-
6.372 (3)(A)2.B.; 10-6.372(3)(B)D.(I); and 10-6.372(3)(B)E. Missouri 
has also changed the word ``shall'' to ``will'' in 10-6.372(4)(B).
    The proposed revisions to 10-6.374 give Missouri responsibility for 
the CSAPR ozone season NOX Trading Program by incorporating 
by reference 40 CFR 97.804 through 40 CFR 97.828 into the Missouri SIP. 
The monitoring and recordkeeping provisions of the CSAPR ozone season 
NOX Trading Program, 40 CFR 97.830 through 40 CFR 97.835 are 
incorporated by reference into 10-6.374.
    The proposed revisions to 10-6.376 give Missouri responsibility for 
the CSAPR SO2 Annual Trading Program by incorporating by 
reference 40 CFR 97.604 through 40 CFR 97.628 into the Missouri SIP. 
The monitoring and recordkeeping provisions of the CSAPR NOX 
Annual Trading Program, 40 CFR 97.630 through 40 CFR 97.635 are 
incorporated by reference into 10-6.376.
    Missouri has also removed the unnecessary use of restrictive 
language including the removal of the word ``required'' in sections 10-
6.376 (3)(A)2.B.; 10-6.376(3)(B)D.(I); and 10-6.372(3)(B)E. Missouri 
has also changed the word ``shall'' to ``will'' in 10-6.376(4)(B). The 
revisions can be found in the docket to this action.
    The EPA is proposing to approve these revisions to the Missouri 
SIP. These revisions incorporate by reference EPA's CSAPR Annual 
NOX and SO2, and ozone season NOX 
trading programs and give Missouri the responsibility to administer 
these programs. The EPA encourages states to include such provisions in 
their state SIPs. The EPA does not believe that the language changes to 
the SIP reduce the stringency of the SIP. The EPA does not believe 
these language changes will affect air quality. Therefore, the EPA is 
proposing to approve Missouri's revisions to 10-6.372, 10-6.374, and 
10-6.376.

V. Have the requirements for approval of a SIP revision been met?

    The state submission has met the public notice requirements for SIP 
submissions in accordance with 40 CFR 51.102. The submission also 
satisfied the completeness criteria of 40 CFR part 51, appendix V.
    The state provided public notice on the January 15, 2019, SIP 
revision from June 25, 2018 through August 2, 2018 and received no 
comments.
    The state provided public notice on the March 7, 2019, SIP 
revisions from August 24, 2018 to October 4, 2018 and received seven 
comments from the EPA during the Regulatory Impact Review. The EPA's 
comments are in the docket for this proposed action. Missouri amended 
the rule in response to the comments and the EPA did not comment 
further. In addition, as explained above, the revision meets the 
substantive SIP requirements of the CAA, including section 110 and 
implementing regulations.

VI. What action is the EPA taking?

    The EPA is proposing to approve the revisions to 10 CSR 10-6.362 
and 10 CSR 10-6.366 that remove the CAIR annual trading program rules 
from the SIP. The EPA is also proposing to

[[Page 36862]]

approve the revisions to 10-6.372, 10-6.374, and 10-6.376 that 
incorporate by reference the provisions of the Federal CSAPR program 
for annual NOX and SO2, and ozone season 
NOX and make other wording changes.
    We are processing this as a proposed action because we are 
soliciting comments on this proposed action. Final rulemaking will 
occur after consideration of any comments.

VII. Incorporation by Reference

    In this document, the 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, the EPA is proposing to 
incorporate by reference the Missouri Regulations described in the 
proposed amendments to 40 CFR part 52 set forth below. The 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).
    Also, in this document, as described in the proposed amendments to 
40 CFR part 52 set forth below, EPA is proposing to remove provisions 
of the EPA-Approved Missouri Regulations and Statutes from the Missouri 
State Implementation Plan, which is incorporated by reference in 
accordance with the requirements of 1 CFR part 51.

VIII. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, the 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 the National Technology 
Transfer and Advancement Act (NTTA) because this rulemaking does not 
involve technical standards; 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).
