National Emission Standards for Hazardous Air Pollutants: 
Municipal Solid Waste Landfills Residual Risk and Technology Review; 
Correction

AGENCY: Environmental Protection Agency (EPA)

ACTION: Final rule.

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

SUMMARY: In this action, the U.S. Environmental Protection Agency (EPA) 
is finalizing technical revisions and clarifications for the national 
emission standards for hazardous air pollutants (NESHAP) for MSW 
Landfills established in the March 26, 2020, final rule. This final 
rule also amends the MSW Landfills NSPS at 40 CFR part 60, subpart XXX, 
to clarify and align the timing of compliance for certain requirements 
involving installation of a gas collection and control system (GCCS) 
under related MSW landfill rules. Additionally, the EPA is revising the 
definition of Administrator in the MSW Landfills Federal Plan that was 
promulgated on May 21, 2021 to clarify who has the authority to 
implement and enforce the applicable requirements. The EPA is also 
making some minor typographical corrections.

DATES: The final rule is effective February 14, 2022.

I. General Information

A. Does this action apply to me?

    Table 1 of this preamble lists the associated regulated industrial 
source categories that are the subject of this final rule. Table 1 is 
not intended to be exhaustive, but rather provides a guide for readers 
regarding the entities that this action is likely to affect. The 
standards, once promulgated, will be directly applicable to the 
affected sources. Federal, state, local, and tribal government entities 
could be affected by this action because these entities are often the 
owners or operators of MSW landfills. As defined in the Initial List of 
Categories of Sources Under Section 112(c)(1) of the Clean Air Act 
Amendments of 1990 (57 FR 31576, July 16, 1992) and Documentation for 
Developing the Initial Source Category List, Final Report (see EPA-450/
3-91-030; July 1992), the MSW Landfills source category is any facility 
that is an entire disposal facility in a contiguous geographical space 
where household waste is placed in or on land. An MSW landfill may also 
receive commercial waste, sludges, and industrial waste. An MSW 
landfill may also receive other types of Resource Conservation and 
Recovery Act (RCRA) Subtitle D wastes (see 40 CFR 257.2) such as 
commercial solid waste, nonhazardous sludge, conditionally exempt small 
quantity generator waste, and industrial solid waste. Portions of an 
MSW landfill may be separated by access roads. An MSW landfill may be 
publicly or privately owned.
    Questions regarding the applicability of this final action to a 
particular entity should be directed to the person listed in the 
preceding FOR FURTHER INFORMATION CONTACT section.

B. Where can I get a copy of this document and other related 
information?

    In addition to being available in the docket, an electronic copy of 
this action is available on the internet. Following signature by the 
EPA Administrator, the EPA will post a copy of this final action at 
https://www.epa.gov/stationary-sources-air-pollution/municipal-solid-waste-landfills-national-emission-standards. Following publication in 
the Federal Register, the EPA will post the Federal Register version of 
this final action at this same website.

C. What is the statutory authority for this action?

    The statutory authority for revisions to the MSW Landfills NESHAP 
(40 CFR part 63, subpart AAAA) is provided by sections 112 and 301 of 
the Clean Air Act (CAA), as amended (42 U.S.C. 7412 and 7401). The 
statutory authority for revisions to the MSW Landfills New Source 
Performance Standards (40 CFR part 60, subpart XXX) and the Federal 
Plan (40 CFR part 62, subpart OOO) is provided by sections 111 and 301 
of the CAA (42 U.S.C. 7411 and 7401).
    The EPA finds that it has good cause to make these revisions 
immediately effective upon publication under section 553(d) of the 
Administrative Procedure Act, 5 U.S.C. 553(d). Section 553(d) provides 
that final rules shall not become effective until 30 days after 
publication in the Federal Register ``except . . . as otherwise 
provided by the agency for good cause.'' The purpose of this provision 
is to ``give affected parties a reasonable time to adjust their 
behavior before the final rule takes effect.'' Omnipoint Corp. v. Fed. 
Commc'n Comm'n, 78 F.3d 620, 630 (DC Cir. 1996); see also United States 
v. Gavrilovic, 551 F.2d 1099, 1104 (8th Cir. 1977) (quoting legislative 
history). Thus, in determining whether good cause exists to waive the 
30-day delay, an agency should, ``balance the necessity for immediate 
implementation against principles of fundamental fairness which require 
that all affected persons be afforded a reasonable amount of time to 
prepare for the effective date of its ruling.'' Gavrilovic, 551 F.2d at 
1105. The EPA has determined that there is good cause under section 
553(d) for making this final rule effective immediately because this 
action clarifies the regulatory provisions that already apply to 
regulatory sources as well as the compliance deadline for controlled 
landfills that become subject to the 2016 MSW Landfills NSPS through 
modification is September 27, 2021. Making this rule effective 
immediately upon publication will minimize confusion and increase 
compliance certainty.

D. Judicial Review

    Under CAA section 307(b)(1), judicial review of this final rule is 
available only by filing a petition for review in the U.S. Court of 
Appeals for the District of Columbia Circuit by April 15, 2022. 
Moreover, under section 307(b)(2) of the CAA, the requirements 
established by

[[Page 8199]]

this final rule may not be challenged separately in any civil or 
criminal proceedings brought by the EPA to enforce these requirements. 
Section 307(d)(7)(B) of the CAA further provides that ``[o]nly an 
objection to a rule or procedure which was raised with reasonable 
specificity during the period for public comment (including any public 
hearing) may be raised during judicial review.'' This section also 
provides a mechanism for the EPA to convene a proceeding for 
reconsideration, ``[i]f the person raising an objection can demonstrate 
to the EPA that it was impracticable to raise such objection within 
[the period for public comment] or if the grounds for such objection 
arose after the period for public comment, (but within the time 
specified for judicial review) and if such objection is of central 
relevance to the outcome of the rule.'' Any person seeking to make such 
a demonstration should submit a Petition for Reconsideration to the 
Office of the Administrator, U.S. EPA, Room 3000, WJC South Building, 
1200 Pennsylvania Ave. NW, Washington, DC 20460, with a copy to both 
the person listed in the preceding FOR FURTHER INFORMATION CONTACT 
section, and the Associate General Counsel for the Air and Radiation 
Law Office, Office of General Counsel (Mail Code 2344A), U.S. EPA, 1200 
Pennsylvania Ave. NW, Washington, DC 20460.

II. Background

A. What is the regulatory development background and legal authority 
for this action?

    The NESHAP regulates HAP emissions from MSW landfills that are 
either major or area sources, and applies to MSW landfills that have 
accepted waste since November 8, 1987, or have additional capacity for 
waste deposition and are major sources, are collocated with major 
sources, or are area source landfills with a design capacity equal to 
or greater than 2.5 million megagrams (Mg) and 2.5 million cubic meters 
(m\3\) and have estimated uncontrolled emissions equal to or greater 
than 50 megagrams per year (Mg/yr) of non-methane organic compounds 
(NMOC). The NESHAP also applies to MSW landfills that have accepted 
waste since November 8, 1987, or have additional capacity for waste 
deposition and include a bioreactor and are major sources, are 
collocated with major sources, or are area source landfills with a 
design capacity equal to or greater than 2.5 million Mg and 2.5 million 
m\3\ that were not permanently closed as of January 16, 2003.
    The EPA completed the residual risk and technology review (RTR) for 
the Municipal Solid Waste (MSW) Landfills source category as regulated 
under the MSW Landfills NESHAP and promulgated amendments to 40 CFR 
part 63, subpart AAAA on March 26, 2020. (85 FR 17244). The rule 
finalized the EPA's determination that risks from this source category 
are acceptable and that the standards provide an ample margin of safety 
to protect public health and prevent an adverse environmental effect. 
There were no revisions to the NESHAP based on our analyses conducted 
under CAA section 112(f). However, the final rule clarified regulatory 
provisions related to emissions during periods of startup, shutdown, 
and malfunction (SSM); revised wellhead operational standards and 
corrective action to improve effectiveness and provide compliance 
flexibility; incorporated provisions from the MSW Landfills NSPS; and 
added requirements for electronic reporting of performance test 
results. The EPA subsequently corrected inadvertent errors in the 
cross-referencing and formatting of the final rule and made minor 
clarifications to the operational and reporting requirements. (85 FR 
64398, October 13, 2020).
    In August 2016, the EPA finalized changes to the NSPS for MSW 
landfills resulting from the EPA's under Clean Air Act (CAA) section 
111. In order to avoid possible confusion regarding which MSW landfills 
would actually be subject to these changes, the EPA established a new 
subpart XXX (40 CFR part 60, subpart XXX) rather than merely updating 
the existing subpart WWW (40 CFR part 60, subpart WWW). One of the key 
changes in the new subpart XXX was the lowering of the emissions 
threshold for installing controls from 50 megagrams per year (Mg/yr) to 
34 Mg/yr. (81 FR 59332, August 29, 2016).
    At the same time, the EPA reviewed the existing emission guideline 
(EG) (subpart Cc) and determined it was appropriate to revise it 
consistent with the promulgation of the new NSPS subpart XXX. Rather 
than merely updating subpart Cc, the EPA determined that the most 
appropriate way to proceed was to establish a new subpart Cf. (81 FR 
59276, August 29, 2016).
    The promulgation of the MSW landfills EG (subpart Cf) triggered 
states' obligation to submit state plans applying the updated EG to 
existing sources located in their states. The EPA found a number of 
states failed to submit state plans for the 2016 MSW Landfills EG. (85 
FR 14474, March 12, 2020). In May of 2021, the EPA promulgated a 
Federal plan to implement the 2016 MSW Landfills EG for existing MSW 
landfills located in jurisdications where the EPA had not approved a 
state or tribal plan. (86 FR 27756, May 21, 2021).

B. What is the purpose of this action?

    On April 13, 2021, the EPA proposed technical revisions and 
clarifications for the NESHAP for MSW Landfills and the EPA proposed 
clarifying amendments to the MSW Landfills NSPS. See 86 FR 19176. In 
this action, the EPA finalizes technical revisions and clarifications 
for the NESHAP for MSW Landfills established in the March 26, 2020, 
final rule. These technical revisions correct inadvertent errors in the 
NESHAP for MSW Landfills. This action clarifies the following: Wellhead 
monitoring requirements for the purpose of identifying excess air 
infiltration; delegation of authority to state, local, or tribal 
agencies for ``emission standards;'' applicability of the General 
Provisions to affected MSW landfills; and handling of monitoring data 
for combustion devices during periods of monitoring system breakdowns, 
repairs, calibration checks, and adjustments. This action also amends 
the MSW Landfills NSPS at 40 CFR part 60, subpart XXX, to clarify the 
timing of compliance for certain requirements of the MSW Landfills NSPS 
for existing MSW landfills that have been modified but previously 
triggered the requirement to install a GCCS under related MSW landfill 
rules. Additionally, the EPA is revising the definition of 
Administrator in the MSW Landfills Federal Plan that was promulgated on 
May 21, 2021, to clarify who is the administrator for the Federal plan 
and the administrator for a state plan. The EPA is also making some 
minor typographical corrections to NESHAP and the Federal Plan.

III. Summary of Changes Since Proposal and Response to Comments

    The EPA received two comment letters on the proposed revisions to 
the MSW Landfills NESHAP and NSPS (EPA-HQ-OAR-2002-0047-0111, EPA-HQ-
OAR-2002-0047-0112). This section summarizes the EPA's response to 
those comments and indicates where the EPA has made additional changes 
to the proposed revisions to the MSW Landfills NESHAP and NSPS, in 
part, in response to those public comments. The changes include 
clarifications to the wellhead monitoring requirements [including test 
methods], and clarifications to the compliance times for various 
landfills, especially those modifying and becoming subject to 40

[[Page 8200]]

CFR part 60, subpart XXX. For more information, see the response to 
comments document, titled, Summary of Public Comments and EPA's 
Responses for the Proposed Corrections to National Emission Standards 
for Hazardous Air Pollutants: Municipal Solid Waste Landfills Residual 
Risk and Technology Review; Correction, which is available in the 
docket for this action.

A. Wellhead Monitoring

    Comment: Commenter (0111) suggested that the EPA add language to 40 
CFR 63.1981(k) to clarify whether or not a 24-hour high temperature 
report is required for wells with landfill gas temperatures greater 
than 170 degrees Fahrenheit but less than an approved higher operating 
value (HOV).
    Response: The EPA is amending 40 CFR 63.1981(j)(2) to clarify that 
the corrective action and corresponding timelines are not required if 
the landfill has an approved HOV. We added the following phrase to the 
end of 40 CFR 63.1981 (j)(2): ``unless a higher operating temperature 
value has been approved by the Administrator for the well under this 
subpart or under 40 CFR part 60, subpart WWW; 40 CFR part 60, subpart 
XXX; or a Federal plan or EPA approved and effective state plan or 
tribal plan that implements either 40 CFR part 60, subpart Cc or 40 CFR 
part 60, subpart Cf.''
    Comment: Commenter (0112) requested that EPA re-evaluate its 
proposal to require five 1-minute averages to be limited to 7 parts per 
million (ppm) variance. The commenter (0112) contends that the proposed 
requirement is unnecessarily prescriptive and says that although this 
low level of variability may be appropriate for some stationary sources 
of air emissions, such as controlled manufacturing processes, landfills 
may experience more variability than this limitation would allow. 
Commenter (0112) asserted that EPA has neither provided an explanation 
for why this requirement is necessary, nor shown that it can be 
achieved by landfills. Moreover, this requirement does not appear to be 
a necessary clarification or correction but rather an entirely new and 
unjustified compliance obligation. Therefore, unless and until EPA 
demonstrates a need for this requirement and that it is achievable by 
landfills, EPA should not finalize it in this corrections rule.
    Response: The EPA believes that a limited variability provision 
would increase the data quality when collecting samples pursuant to 40 
CFR 1961(a)(5)(vi)(D). However, the EPA agrees with the commenter that 
the CO concentrations can, under certain conditions (e.g., underground 
fires), exhibit short term CO variability higher than 7 ppm. Therefore, 
the EPA has removed the 7 ppm variability requirement and may revisit 
this when more data is available.
    Comment: Commenter (0112) requested that the EPA clarify language 
in 40 CFR 63.1961(a)(5)(vii) directing that enhanced monitoring ``must 
begin 7 days after the first measurement'' to provide that monitoring 
``must begin within 7 days to account for landfill operating hours, 
including weekends and holidays.''
    Response: The EPA has revised 40 CFR 63.1961(a)(5)(vii) to clarify 
that the requirement is to begin enhanced monitoring 7 calendar days 
after the first measurement of landfill gas temperature greater than 
62.8 degrees Celsius (145 degrees Fahrenheit). Decomposition of waste 
and monitoring a landfill are 24-hour per day/365 day per year 
operation where conditions change constantly. The EPA determined that 
it is reasonable and necessary to begin enhanced monitoring within 7 
calendar days to keep a check on high temperature conditions in the 
landfill and minimize the potential for a landfill fire.

B. Compliance Timing

    In the proposed rule, the EPA requested comment on whether the 
proposed modifications to the 2016 MSW Landfills NSPS regulations 
adequately clarify the expected compliance deadlines for controlled 
landfills that become subject to the 2016 MSW Landfills NSPS through 
modification and/or whether other approaches are needed to align the 
timing provisions of the 2016 MSW Landfills NSPS with the timing 
provisions of the MSW Landfills NESHAP. (86 FR 19176, 19182, April 13, 
2021)
    Comment: Commenter (0111) requested that the EPA should specify 
compliance deadlines for three categories of landfills:
    (1) Landfills with an NMOC emission rate less than 34 megagrams per 
year that become subject to subpart XXX through modification;
    (2) uncontrolled landfills with an NMOC emission rate between 34 
and 50 megagrams per year that become subject to subpart XXX through 
modification; and
    (3) controlled landfills that become subject to subpart XXX through 
modification.
    Response: The EPA recognizes that from July 17, 2014 (the 
applicability date of the NSPS) to June 21, 2021 (the effective date of 
the Federal plan at 40 CFR part 62 subpart OOO), landfills that modify 
could become subject to 40 CFR part 60, subpart XXX after having 
previously been subject to 40 CFR part 62, subpart GGG; 40 CFR part 60, 
subpart WWW; or a state plan implementing 40 CFR part 60, subpart Cf or 
subpart Cc. By virtue of this final action, the EPA is clarifying that 
landfills that meet the definition of a ``controlled landfill'' would 
not receive an additional 30 months to comply when they transition to 
subpart XXX.
    The EPA notes that after June 21, 2021, all three groups of 
landfills that modify as identified in this comment will have been 
previously subject only to either a state plan implementing 40 CFR part 
62, subpart Cf, or 40 CFR part 62, subpart OOO to 40 CFR part 60, 
subpart XXX. The EPA is clarifying in this rule that compliance timing 
for landfills that become subject to subpart XXX after previously being 
subject to the Federal plan subpart OOO depends on whether the facility 
is a legacy controlled landfill, a controlled landfill or an 
uncontrolled landfill, and the results and timing of the landfill's 
NMOC emission rate report.
    Landfills with an NMOC emission rate less than 34 megagrams per 
year that later become subject to subpart XXX through modification and 
have not installed controls should follow the requirements in subpart 
XXX, including the 30-month window to install and operate a GCCS. The 
landfill will submit their first NMOC report within 90 days of the date 
of construction or modification. The landfill could submit a revised 
NMOC report based on Tier 2 within 180 days of that first report, if 
desired.
    For uncontrolled landfills with an NMOC emission rate equal to or 
greater than 34 but less than 50 megagrams per year that later become 
subject to subpart XXX through modification, we are clarifying that the 
30-month clock for previously uncontrolled landfills will begin at the 
first report containing NMOC emissions greater than or equal to 34 Mg/
yr NMOC that was submitted under any of the following subparts: 40 CFR 
part 60, subpart XXX or a state plan implementing subpart Cf; or 40 CFR 
part 62, subpart OOO. We are starting the 30-month clock at the NMOC 
report submitted under that subpart for these landfills with an NMOC 
emission rate equal to or greater than 34 but less than 50 megagrams 
per year because the landfill was not otherwise subject to any 
requirement to install and operate GCCS until they became subject to 
these subparts.

[[Page 8201]]

    For controlled landfills that become subject to subpart XXX through 
modification, we do not intend to restart the 30-month clock for 
landfills reporting NMOC emissions greater than or equal to 50 Mg/yr 
NMOC under 40 CFR part 60, subpart WWW or Cc; or 40 CFR part 62, 
subpart GGG, and that submitted a design plan before the effective date 
of these 2021 subpart XXX amendments. These landfills already started 
the ``control'' process under the previous subparts and must stay on 
that previously triggered 30-month timeframe to install a GCCS in a 
timely manner.
    Comment: Commenter (0112) disagreed with the EPA's proposal not to 
allow 30 months to install and operate a GCCS as the landfill 
transitions to a new subpart. However, the commenter (0112) recognized 
that landfills with emissions 50 Mg/yr NMOC or greater will be required 
to begin complying with the same requirements to install and operate 
GCCS pursuant to NESHAP AAAA as of September 28, 2021.
    Response: For controlled landfills that become subject to subpart 
XXX through modification, the EPA does not agree that it would be 
appropriate to restart the 30-month clock for landfills reporting NMOC 
emissions greater than or equal to 50 Mg/yr NMOC under 40 CFR part 60, 
subpart WWW or Cc; or 40 CFR part 62, subpart GGG and that submitted a 
design plan before the effective date of these 2021 subpart XXX 
amendments. These landfills already started the ``control'' process 
under the previous subparts and it is reasonable to require these 
landfills to stay on that 30-month timeframe to install a GCCS in a 
timely manner. The commenter has not provided any information that 
would justify any further delay in the implementation of GCCS.
    Comment: Commenter (0112) disagreed with using any subpart WWW 
reports between 34 and 50 Mg/yr NMOC as the trigger for the 30-month 
timeframe for installation of GCCS since this would not allow the 
landfill sufficient time to prepare a design plan and install the GCCS. 
The commenter (0112) suggested alternative regulatory text.
    Response: The EPA recognizes that previous regulatory requirements 
are based on an emission rate threshold of 50 Mg/yr NMOC and that newer 
regulatory requirements are based on an emission rate threshold of 34 
Mg/yr NMOC. With these technical revisions, we intend to clarify the 
application of the 30-month clock for previously uncontrolled landfills 
reporting NMOC emissions greater than or equal to 34 Mg/yr NMOC and 
less than 50 Mg/yr NMOC under 40 CFR part 60, subpart XXX or Cf; or 40 
CFR part 62, subpart OOO. We are starting the 30-month clock at the 
NMOC report submitted under those subparts for those landfills that 
exceeded 34 Mg/yr NMOC because the 34-50 Mg/yr NMOC threshold did not 
apply until they became subject to these subparts.
    However, we do not intend to restart the 30-month clock for 
landfills reporting NMOC emissions greater than or equal to 50 Mg/yr 
NMOC under 40 CFR part 60, subpart WWW or Cc; or 40 CFR part 62, 
subpart GGG and that submitted a design plan before the effective date 
of these 2021 subpart XXX amendments. These landfills already started 
the ``control'' process under the previous subparts and it is 
reasonable to require these landfills to stay on that 30-month 
timeframe to install a GCCS in a timely manner.
    The EPA is revising 40 CFR 60.762(b)(2)(ii)(A) to read as follows:

    (A) The first annual report submitted under this subpart or part 
62 of this subchapter in which the NMOC emission rate equals or 
exceeds 34 megagrams per year, unless Tier 2 or Tier 3 sampling 
demonstrates that the NMOC emission rate is less than 34 megagrams 
per year, as specified in Sec.  60.767(c)(4); or

    This approach points to 40 CFR part 60, subpart XXX or 40 CFR part 
62 (the Federal plan subpart OOO or state plans implementing subpart 
Cf). When these subpart XXX amendments are finalized, all ``existing'' 
landfills will be subject to the state and/or Federal plan implementing 
subpart Cf because the Federal plan became effective on June 21, 2021. 
Subpart OOO handles the legacy controllers separately and gives a full 
30 months for landfills with NMOC emissions greater than 34 Mg/yr and 
less than 50 Mg/yr.

C. Technical and Typographical Corrections

    In this final action, the EPA is revising the definition of 
Administrator at 40 CFR 62.16730 in the MSW Landfills Federal Plan that 
was promulgated on May 21, 2021 (86 FR 27756). The revision makes the 
definition consistent with other Federal plans such as the Federal Plan 
Requirements for Sewage Sludge Incineration Units (40 CFR part 62, 
subpart LLL), which distinguishes between the administrator of the 
Federal plan and the administrator of a state plan. In developing the 
MSW Landfills Federal Plan, the EPA inadvertently retained the 
definition of Administrator from the Emission Guidelines (40 CFR part 
60, subpart Cf), which was written in the context of states preparing a 
state plan. As currently written, the definition could be interpreted 
to allow non-delegated authority to implement and enforce the Federal 
plan. In the context of the Federal plan, the revised definition of 
Administrator clarifies that the EPA Administrator or his/her 
authorized representative have the authority to implement and enforce 
the Federal plan. To add clarity in the context of developing State 
plans, the EPA has further revised the definition of Administrator to 
clearly identify the director of the state air pollution control agency 
or his/her authorized representative, which will better allow states to 
incorporate by reference the Federal plan as their state rule applying 
to landfills in the state.
    The EPA is also correcting typographical errors in the MSW 
Landfills NESHAP that were published in the Federal Register on March 
26, 2020 (85 FR 17244) and the MSW Landfills Federal Plan that was 
published in the Federal Register on May 21, 2021 (86 FR 27756). In the 
MSW Landfills NESHAP, the EPA is correcting 40 CFR 63.1981(n) to change 
September 2, 2021 to September 27, 2021. In the MSW Landfills Federal 
Plan, the EPA is correcting a cross reference error in 40 CFR 
62.16712(b) and (c). Both paragraphs incorrectly refer to 40 CFR 
62.16712(c)(3), which does not exist. The correct reference is to 40 
CFR 62.16712(d). Finally, the EPA is correcting the omission of the 
word ``is'' in 40 CFR 62.16714(a)(4), so that the correct reading is: 
The landfill is in the closed landfill subcategory and has an NMOC 
emission rate greater than or equal to 50 megagrams per year.
    Section 553 of the Administrative Procedure Act, 5 U.S.C. 
553(b)(B), provides that, when an agency for good cause finds that 
notice and public procedure are impracticable, unnecessary, or contrary 
to the public interest, the agency may issue a rule without providing 
notice and an opportunity for public comment. The EPA has determined 
that there is good cause for making these technical and typographical 
changes without prior proposal and opportunity for comment because, as 
explained here above, the technical correction to the definition of 
Administrator and the typographical changes are noncontroversial in 
nature and do not substantively change the requirements of the MSW 
Landfills regulations. Thus, notice and opportunity for public comment 
are unnecessary for these changes. The EPA finds that this constitutes 
good cause under 5 U.S.C. 553(b)(B).

IV. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was, 
therefore, not submitted to the Office of Management and Budget (OMB) 
for review.

B. Paperwork Reduction Act (PRA)

    This action does not impose any new information collection burden 
under the PRA. OMB has previously approved the information collection 
activities contained in the existing regulations and has assigned OMB 
control number 2060-0505 for the NESHAP and OMB control number 2060-
0697 for the NSPS. The revisions include technical corrections to the 
NESHAP and NSPS and do not pose any changes to the information 
collection burden for either.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. In 
making this determination, EPA concludes that the impact of concern for 
this rule is any significant adverse economic impact on small entities 
and that the agency is certifying that this rule will not have a 
significant economic impact on a substantial number of small entities 
if the rule has no net burden on the small entities subject to the 
rule. This action includes only technical corrections to provisions 
from the March 26, 2020, final RTR rulemaking and clarifying amendments 
to 2016 MSW Landfills NSPS and does not implement new requirements. We 
have therefore concluded that this action will have no net regulatory 
burden for all directly regulated small entities.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more as described in UMRA, 2 U.S.C. 1531-1538, and does not 
significantly or uniquely affect small governments. Although state, 
local, or tribal governments own and operate landfills subject to these 
final amendments, this action includes only technical corrections to 
provisions from the March 26, 2020, final RTR rulemaking and clarifying 
amendments to the 2016 MSW Landfills NSPS and there are no impacts 
resulting from this regulatory action.

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the states, on the relationship between 
the national government and the states, or on the distribution of power 
and responsibilities among the various levels of government.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action has tribal implications as specified in Executive Order 
13175. However, it will neither impose substantial direct compliance 
costs on federally recognized tribal governments nor preempt tribal 
law. As explained in the March 26, 2020, final rule, the EPA previously 
identified one tribe that owns three landfills that are potentially 
subject to the MSW Landfills NESHAP. However, this action includes only 
technical corrections to provisions from the March 26, 2020, final RTR 
rulemaking and clarifying amendments to the subpart XXX NSPS and does 
not impose any new requirements on tribes.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. This action is not subject to 
Executive Order 13045 because it does not concern an environmental 
health risk or safety risk.

H. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 because it is 
not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    The EPA believes that this action is not subject to Executive Order 
12898 (59 FR 7629; February 16, 1994) because it does not establish an 
environmental health or safety standard. This regulatory action is a 
technical correction to a previously promulgated regulatory action and 
does not have any impact on human health or the environment.

K. Congressional Review Act (CRA)

    This action is subject to the CRA and the EPA will submit a rule 
report to each House of the Congress and to the Comptroller General of 
the United States. This action is not a ``major rule'' as defined by 5 
U.S.C. 804(2).

[[Page 8204]]

    (A) Collect the sample from the wellhead sampling port in a 
passivated canister or multi-layer foil gas sampling bag (such as the 
Cali-5-Bond Bag) and analyze that sample using EPA Method 10 of 
appendix A-4 to part 60 of this chapter, or an equivalent method with a 
detection limit of at least 100 ppmv of carbon monoxide in high 
concentrations of methane; or
* * * * *
    (C) When sampling directly from the wellhead, you must sample for 5 
minutes plus twice the response time of the analyzer. These values must 
be recorded. The five 1-minute averages are then averaged to give you 
the carbon monoxide reading at the wellhead.
    (D) When collecting samples in a passivated canister or multi-layer 
foil sampling bag, you must sample for the period of time needed to 
assure that enough sample is collected to provide five (5) consecutive, 
1-minute samples during the analysis of the canister or bag contents, 
but no less than 5 minutes plus twice the response time of the 
analyzer. The five (5) consecutive, 1-minute averages are then averaged 
together to give you a carbon monoxide value from the wellhead.
    (vii) The enhanced monitoring described in this paragraph (a)(5) 
must begin 7 calendar days after the first measurement of landfill gas 
temperature greater than 62.8 degrees Celsius (145 degrees Fahrenheit);

12. Amend Sec.  63.1975 by revising the introductory text to read as 
follows:

Sec.  63.1975  How do I calculate the 3-hour block average used to 
demonstrate compliance?

    Before September 28, 2021, averages are calculated in the same way 
as they are calculated in Sec.  60.758(b)(2)(i) of this subchapter for 
average combustion temperature and Sec.  60.758(c) for 3-hour average 
combustion temperature for enclosed combustors, except that the data 
collected during the events listed in paragraphs (a) through (d) of 
this section are not to be included in any average computed under this 
subpart. Beginning no later than September 27, 2021, averages are 
calculated according to Sec.  63.1983(b)(2)(i) for average combustion 
temperature and Sec.  63.1983(c)(1)(i) for 3-hour average combustion 
temperature for enclosed combustors, except that the data collected 
during the event listed in paragraph (a) of this section are not to be 
included in any average computed under this subpart.

    (2) For corrective action that is required according to Sec.  
63.1960(a)(3) or (4) and is expected to take longer than 120 days after 
the initial exceedance to complete, you must submit the root cause 
analysis, corrective action analysis, and corresponding implementation 
timeline to the Administrator as soon as practicable but no later than 
75 days after the first measurement of positive pressure or temperature 
monitoring value of 62.8 degrees Celsius (145 degrees Fahrenheit) or 
above unless a higher operating temperature value has been approved by 
the Administrator for the well under this subpart or under 40 CFR part 
60, subpart WWW; 40 CFR part 60, subpart XXX; or a Federal plan or EPA 
approved and effective state plan or tribal plan that implements either 
40 CFR part 60, subpart Cc or 40 CFR part 60, subpart Cf. The 
Administrator must approve the plan for corrective action and the 
corresponding timeline.
* * * * *
    (n) Claims of force majeure. Beginning no later than September 27, 
2021, if you are required to electronically submit a report through 
CEDRI in the EPA's CDX, you may assert a claim of force majeure for 
failure to comply timely with the reporting requirement. To assert a 
claim of force majeure, you must meet the following requirements:
