40 CFR Part 52

[EPA-R04-OAR-2020-0129; FRL-10025-80-Region 4]


Air Plan Approval; AL; NOX SIP Call and Removal of CAIR

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final 
action to approve a State Implementation Plan (SIP) revision submitted 
by the State of Alabama through a letter dated February 27, 2020, to 
add regulations maintaining compliance with the State's nitrogen oxides 
(NOX) SIP Call obligations for large non-electricity 
generating units (non-EGUs), to repeal the State's previously sunsetted 
NOX Budget Trading Program regulations, and to repeal the 
State's Clean Air Interstate Rule (CAIR) regulations. EPA is also 
conditionally approving into the SIP state regulations that establish 
monitoring and reporting requirements for units subject to the 
NOX SIP Call, including alternative monitoring options for 
certain sources for NOX SIP Call purposes. In addition, EPA 
is making ministerial changes to reflect the State's renumbering of an 
existing regulation for ``New Combustion Sources.''

DATES: This rule is effective August 6, 2021.

ADDRESSES: EPA has established a docket for this action under Docket 
Identification No. EPA-R04-OAR-2020-0129. All documents in the docket 
are listed on the www.regulations.gov website. Although listed in the

SUPPLEMENTARY INFORMATION: 

I. Background and Purpose

    Under Clean Air Act (CAA or Act) section 110(a)(2)(D)(i)(I), also 
called the good neighbor provision, states are required to address the 
interstate transport of air pollution. Specifically, the good neighbor 
provision requires that each state's implementation plan contain 
adequate provisions to prohibit air pollutant emissions from within the 
state that will significantly contribute to nonattainment of the 
national ambient air quality standards (NAAQS), or that will interfere 
with maintenance of the NAAQS, in any other state.
    In October 1998 (63 FR 57356), 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'' (NOX SIP Call). The NOX SIP 
Call required eastern states, including Alabama, to submit SIPs that 
prohibit excessive emissions of ozone season NOX by 
implementing statewide emissions budgets.\1\ The NOX SIP 
Call addressed the good neighbor provision for the 1979 ozone NAAQS and 
was designed to mitigate the impact of transported NOX 
emissions, one of the precursors of ozone.\2\ EPA developed the 
NOX Budget Trading Program, an allowance trading program 
that states could adopt to meet their obligations under the 
NOX SIP Call. This trading program allowed the following 
sources to participate in a regional cap and trade program: Generally 
EGUs with capacity greater than 25 megawatts (MW); and large industrial 
non-EGUs, such as boilers and combustion turbines, with a rated heat 
input greater than 250 million British thermal units per hour (MMBtu/
hr). The NOX SIP Call also identified potential reductions 
from cement kilns and stationary internal combustion engines.
---------------------------------------------------------------------------

    \1\ See 63 FR 57356 (October 27, 1998).
    \2\ As originally promulgated, the NOX SIP Call also 
addressed good neighbor obligations under the 1997 8-hour ozone 
NAAQS, but EPA subsequently stayed and later rescinded the rule's 
provisions with respect to that standard. See 65 FR 56245 (September 
18, 2000); 84 FR 8422 (March 8, 2019).
---------------------------------------------------------------------------

    To comply with the NOX SIP Call requirements, in 2001, 
the Alabama Department of Environmental Management (ADEM) submitted a 
revision to add new rule sections to the SIP-approved version of 
Alabama Administrative Code Chapter 335-3-1, General Provisions, and 
Chapter 335-3-8, Control of Nitrogen Oxides Emissions. EPA approved the 
revision as compliant with Phase I of the NOX SIP Call in 
2001. See 66 FR 36919 (July 16, 2001). The approved revision required 
EGUs and large non-EGUs in the State to participate in the 
NOX Budget Trading Program beginning in 2004. In 2005, 
Alabama submitted, and EPA approved, a SIP revision to address 
additional emissions reductions required for the NOX SIP 
Call under Phase II. See 70 FR 76694 (December. 28, 2005).
    In 2005, EPA published CAIR, which required several eastern states, 
including Alabama, to submit SIPs that prohibited emissions consistent 
with revised ozone season (and annual) NOX budgets. See 70 
FR 25162 (May 12, 2005); see also 71 FR 25328 (April 28, 2006). CAIR 
addressed the good neighbor provision for the 1997 ozone NAAQS and 1997 
fine particulate matter (PM2.5) NAAQS and was designed to 
mitigate the impact of transported NOX emissions with 
respect to ozone and PM2.5. CAIR established several trading 
programs that EPA implemented through federal implementation plans 
(FIPs) for EGUs greater than 25 MW in each affected state, but not 
large non-EGUs; states could submit SIPs to replace the FIPs that 
achieved the required emission reductions from EGUs and/or other types 
of sources.\3\ When the CAIR trading program for ozone season 
NOX was implemented beginning in 2009, EPA discontinued 
administration of the NOX Budget Trading Program; however, 
the requirements of the NOX SIP Call continued to apply.
---------------------------------------------------------------------------

    \3\ CAIR had separate trading programs for annual sulfur dioxide 
(SO2) emissions, seasonal NOX emissions, and 
annual NOX emissions.
---------------------------------------------------------------------------

    On October 1, 2007 (72 FR 55659), EPA approved changes to Alabama's 
SIP that incorporated requirements for CAIR. Consistent with CAIR's 
requirements, EPA approved a SIP revision in which Alabama regulations: 
(1) Sunset its NOX Budget Trading Program requirements, and 
(2) incorporated CAIR annual and ozone season NOX state 
trading programs. See 72 FR 55659. Participation of EGUs in the CAIR 
ozone season NOX trading program addressed the State's 
obligation under the NOX SIP Call for those units, and 
Alabama also chose to require non-EGUs subject to the NOX 
SIP Call to participate in the same CAIR trading program. In this 
manner, Alabama's CAIR rules incorporated into the SIP addressed the 
State's obligations under the NOX SIP Call with respect to 
both EGUs and non-EGUs.
    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. See North Carolina v. EPA, 531 F.3d 896, 
modified on rehearing, 550 F.3d 1176 (D.C. Cir. 2008). The ruling 
allowed CAIR to remain in effect temporarily until a replacement rule 
consistent with the court's opinion was developed. While EPA worked on 
developing a replacement rule, the CAIR program continued to be 
implemented with the NOX annual and ozone season trading 
programs beginning in 2009 and the SO2 annual trading 
program beginning in 2010.
    Following the D.C. Circuit's remand of CAIR, EPA promulgated the 
Cross-State Air Pollution Rule (CSAPR) to replace CAIR and address good 
neighbor obligations for the 1997 ozone NAAQS, the 1997 
PM2.5 NAAQS, and the 2006 PM2.5 NAAQS. See 76 FR 
48208 (August 8, 2011). Through FIPs, CSAPR required EGUs in eastern 
states, including Alabama, to meet annual and ozone season 
NOX emission budgets and annual SO2 emission 
budgets implemented through new trading programs. Implementation of 
CSAPR began on January 1, 2015.\4\ CSAPR also contained provisions that 
would sunset CAIR-related obligations on a schedule coordinated with 
the implementation of the CSAPR compliance requirements. Participation 
by a state's EGUs in the CSAPR trading program for ozone season 
NOX generally addressed the state's obligation under the NOx 
SIP Call for EGUs. CSAPR did not initially contain provisions allowing 
states to incorporate large non-EGUs into that trading program to meet 
the requirements of the NOX SIP Call for non-EGUs. EPA also 
stopped

[[Page 35612]]

administering CAIR trading programs with respect to emissions occurring 
after December 31, 2014.\5\
---------------------------------------------------------------------------

    \4\ See 79 FR 71663 (December 3, 2014).
    \5\ See 79 FR 71663 (December 3, 2014) and 81 FR 13275 (March 
14, 2016).
---------------------------------------------------------------------------

    To comply with CSAPR, Alabama adopted SO2 and 
NOX CSAPR trading program rules, including budgets, in ADEM 
Administrative Code Chapters 335-3-5 and 335-3-8. On August 31, 2016, 
EPA approved Alabama's CSAPR annual SO2 and annual 
NOX trading program rules into the SIP.\6\ See 81 FR 59869. 
Because EPA stopped administering the CAIR trading programs after 2014, 
the approved CAIR rules in the State's SIP have not been implemented 
for several years. Furthermore, ADEM repealed all CAIR and CAIR-related 
regulations from Alabama Administrative Code Chapters 335-3-1, 335-3-5, 
and 335-3-8 on December 9, 2011.\7\ Even though the CAIR programs were 
not being implemented in Alabama, ozone season NOx emissions have 
remained well below the NOX SIP Call budget levels.
---------------------------------------------------------------------------

    \6\ In the 2016 action, EPA did not act on the portion of 
Alabama's SIP submittal intended to replace Alabama units' 
obligations to participate in CSAPR's federal trading program for 
ozone-season NOx emissions.
    \7\ Although CAIR-related regulations were repealed from ADEM 
Administrative Code on December 11, 2011, the repeal of the 
regulations was not effective until February 20, 2015. EPA is now 
proposing to remove the repealed regulations from the SIP.
---------------------------------------------------------------------------

    After litigation that reached the Supreme Court, the D.C. Circuit 
generally upheld CSAPR but remanded several state budgets to EPA for 
reconsideration. EME Homer City Generation, L.P. v. EPA, 795 F.3d 118, 
129-30 (D.C. Cir. 2015). EPA addressed the remanded ozone season 
NOX budgets in the Cross-State Air Pollution Rule Update for 
the 2008 Ozone NAAQS (CSAPR Update), which also partially addressed 
eastern states' good neighbor obligations for the 2008 ozone NAAQS. See 
81 FR 74504 (October 26, 2016). The air quality modeling for the CSAPR 
Update demonstrated that Alabama contributes significantly to 
nonattainment and/or interferes with maintenance of the 2008 ozone 
NAAQS in other states. The CSAPR Update reestablished an option for 
most states to meet their ongoing obligations for non-EGUs under the 
NOX SIP Call by including the units in the CSAPR Update 
trading program.
    The CSAPR Update trading program replaced the original CSAPR 
trading program for ozone season NOX for most covered 
states. On October 6, 2017, EPA approved Alabama's CSAPR Update ozone 
season NOX trading program rules for EGUs into the State's 
SIP.\8\ See 82 FR 46674. Alabama's EGUs participate in the CSAPR Update 
trading program, generally also addressing the state's obligations 
under the NOX SIP Call for EGUs. However, Alabama elected 
not to include its large non-EGUs in the CSAPR Update ozone season 
trading program. Because Alabama's large non-EGUs no longer participate 
in any CSAPR or CSAPR Update trading program for ozone season NOx 
emissions, the NOX SIP Call regulations at 40 CFR 
51.121(r)(2) as well as anti-backsliding provisions at 40 CFR 51.905(f) 
and 40 CFR 51.1105(e) require these non-EGUs to maintain compliance 
with NOX SIP Call requirements in some other way.
---------------------------------------------------------------------------

    \8\ This action approved CSAPR and CSAPR Update-related 
provisions of Alabama SIP submissions dated October 26, 2015, and 
May 19, 2017.
---------------------------------------------------------------------------

    Under 40 CFR 51.121(f)(2) of the NOx SIP Call regulations, where a 
State's SIP contains control measures for EGUs and large non-EGU 
boilers and combustion turbines, the SIP must contain enforceable 
limits on the ozone season NOx mass emissions from these sources. In 
addition, under 40 CFR 51.121(i)(4) of the NOx SIP Call regulations as 
originally promulgated, the SIP also had to require these sources to 
monitor emissions according to the provisions of 40 CFR part 75, which 
generally entails the use of continuous emission monitoring systems 
(CEMS). Alabama triggered these requirements by including control 
measures in its SIP for these types of sources, and the requirements 
have remained in effect despite the discontinuation of the 
NOX Budget Trading Program after the 2008 ozone season. On 
March 8, 2019, EPA revised some of the regulations that were originally 
promulgated in 1998 to implement the NOX SIP Call.\9\ The 
revision gave states covered by the NOX SIP Call greater 
flexibility concerning the form of the NOx emissions monitoring 
requirements that the states must include in their SIPs for certain 
emissions sources. The revision amended 40 CFR 51.121(i)(4) to make 
Part 75 monitoring, recordkeeping, and reporting optional, such that 
SIPs may establish alternative monitoring requirements for SIP Call 
budget units that meet the general requirements of 40 CFR 51.121(f)(1) 
and (i)(1). Under the updated provision, a state's implementation plan 
still needs to include some form of emissions monitoring requirements 
for these types of sources, consistent with the NOX SIP 
Call's general enforceability and monitoring requirements at Sec. Sec.  
51.121(f)(1) and (i)(1), respectively, but states are no longer be 
required to satisfy these general NOX SIP Call requirements 
specifically through the adoption of 40 CFR part 75 monitoring 
requirements.
---------------------------------------------------------------------------

    \9\ See ``Emissions Monitoring Provisions in State 
Implementation Plans Required Under the NOX SIP Call,'' 
84 FR 8422 (March 8, 2019).
---------------------------------------------------------------------------

    After evaluating the various options available following EPA's 
March 8, 2019, revision to the NOX SIP Call requirements, 
ADEM revised its regulations to address NOX SIP Call 
requirements and adopt alternative monitoring options for certain large 
non-EGUs. The changes require large non-EGUs in the State to address 
the NOX SIP Call's requirements for enforceable limits on 
ozone season NOX mass emissions in a manner that does not 
rely on the administration of an interstate trading program. In 
addition, Alabama had previously revised its regulations to remove 
NOX Budget Trading Program and CAIR trading program 
provisions after EPA stopped administering those programs. Alabama also 
revised its regulations non-substantively to renumber the regulation 
titled, ``New Combustion Sources'' from Rule 335-3-8-.14 to Rule 335-3-
8-.05. The February 27, 2020, SIP revision submitted by ADEM requests 
approval into the SIP of all of these rule changes.
    For a comprehensive discussion of EPA's analysis and rationale for 
approval of the State's submittal, please refer to EPA's March 3, 2021, 
notice of proposed rulemaking. See 86 FR 12305 (March 3, 2021). EPA 
received no comments on the proposed approval of Alabama's SIP.

II. Incorporation by Reference

    In this document, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, EPA is finalizing the incorporation by reference of Alabama 
Administrative Code Rule 335-3-8-.71, ``NOX Budget 
Program,'' which reestablishes enforceable limits on ozone season 
NOX mass emission for certain units as required by EPA's 
NOX SIP Call regulations, and conditionally approving Rule 
335-3-8-.72, ``NOX Budget Program Monitoring and 
Reporting,'' which establishes alternative emission monitoring 
requirements for the units, both state effective on April 13, 2020. 
Further, EPA is approving the renumbering of Rule 335-3-8-.14, ``New 
Combustion Sources'' to 335-3-8-.05, ``New Combustion Sources,'' state 
effective January 16, 2012. Also in this document, EPA is finalizing 
the removal of provisions from the Alabama State

[[Page 35613]]

Implementation Plan regarding the State's NOX Budget Trading 
Program and CAIR trading program regulations at Rules 335-3-1-.14, 335-
3-1-.16,\10\ 335-3-5-.06 through 335-3-5-.08, 335-3-5-.11 through 335-
3-5-.14, 335-3-8-.05 through 335-3-8-.13, 335-3-8-.16 through 335-3-
8-.18, 335-3-8-.20, 335-3-8-.21, 335-3-8-.23 through 335-3-8-.27, 335-
3-8-.29, 335-3-8-.30, 335-3-8-.32, and 335-3-8-.33, which were 
incorporated by reference in accordance with the requirements of 1 CFR 
part 51. EPA has made, and will continue to make, these materials 
generally available through www.regulations.gov and at the EPA Region 4 
Office (please contact the person identified in the For Further 
Information Contact section of this preamble for more information). 
Therefore, the revised materials as stated above, have been approved by 
EPA for inclusion in the State implementation plan, have been 
incorporated by reference by EPA into that plan, are fully federally 
enforceable under sections 110 and 113 of the CAA as of the effective 
date of the final rulemaking of EPA's approval, and will be 
incorporated by reference by the Director of the Federal Register in 
the next update to the SIP compilation.\11\
---------------------------------------------------------------------------

    \10\ Rule 335-3-1-.16 was originally approved into the Alabama 
SIP on March 26, 2009 (74 FR 13118). However, inadvertently, Rule 
335-3-1-.16 was never added to the table of EPA-Approved Alabama 
Regulations found at 40 CFR 52.50(c). In effect, there is no need to 
remove an entry for this Section from the table of EPA-Approved 
Alabama Regulations because EPA is now approving the removal of this 
Rule from the Alabama SIP and an approval entry was never included.
    \11\ See 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------

III. Final Action

    EPA is taking final action to approve revisions to Alabama's SIP, 
which the State submitted to EPA on February 27, 2020, regarding the 
NOX Budget Program. EPA has determined that these portions 
of Alabama's SIP meet the applicable requirements of sections 110 and 
172 of the CAA and applicable regulatory requirements at 40 CFR part 
51. In addition, EPA is conditionally approving certain revisions, as 
described above, regarding the NOX Budget Program's 
monitoring and reporting requirements, per Alabama's commitment through 
a letter dated September 15, 2020.

IV. 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. See 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. 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).
    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 as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000), nor will it impose substantial direct 
costs on tribal governments or preempt tribal law.
    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 September 7, 2021. 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. This action may not be challenged later in proceedings to 
enforce its requirements. See section 307(b)(2).
