SUPPLEMENTARY INFORMATION: Throughout this document wherever ``we,''
``us,'' or ``our'' is used, we mean the EPA.
I. Background
Section 111 of the CAA, ``Standards of Performance for New
Stationary Sources,'' directs the EPA to establish emission standards
for stationary sources of air pollution that could potentially endanger
public health or welfare. These standards are referred to as New Source
Performance Standards (NSPS). Section 111(d) addresses the process by
which the EPA and states regulate standards of performance for existing
sources. When NSPS are promulgated for new sources, section 111(d) and
EPA regulations require that the EPA publish an Emission Guideline (EG)
to regulate the same pollutants from existing facilities. While NSPS
are directly applicable to new sources, EG for existing sources
(designated facilities) are intended for states to use to develop a
state plan to submit to the EPA.
State plan submittal and revisions under CAA section 111(d) must be
consistent with the applicable EG and the requirements of 40 CFR part
60, subpart B, and part 62, subpart A. The regulations at 40 CFR part
60, subpart B, contain general provisions applicable to the adoption
and submittal of state plans under CAA section 111(d). Additionally, 40
CFR part 62, subpart A, provides the procedural framework by which the
EPA will approve or disapprove such plans submitted by a state. Once
approved by the EPA, the state plan becomes federally enforceable. If a
state does not submit an approvable state plan to the EPA, the EPA is
responsible for developing, implementing, and enforcing a federal plan.
The MSW landfills NSPS for new landfills and EG for existing
landfills were first promulgated by EPA on March 12, 1996, in 40 CFR
part 60, subparts WWW and Cc, respectively (61 FR 9905). On August 29,
2016, the EPA finalized revisions to the MSW landfills NSPS and EG in
40 CFR part 60, subparts XXX and Cf, respectively (81 FR 59332; 81 FR
59313). The 2016 EG revision updates the control requirements and
monitoring, reporting, and recordkeeping provisions for existing MSW
landfill sources.
The current MSW landfills EG, found at 40 CFR part 60, subpart Cf,
concerns the regulation of landfill gas and its
[[Page 59377]]
components, including methane, from MSW landfills for which
construction, reconstruction, or modification was commenced on or
before July 17, 2014. The deadline to submit a state plan to the EPA
was May 30, 2017. On May 21, 2021, EPA finalized the MSW landfills
federal plan in 40 CFR part 62, subpart OOO (86 FR 27756). The MSW
landfills federal plan at 40 CFR part 62, subpart OOO, applies to
states that do not have an EPA-approved state plan. The MSW landfills
federal plan is currently in effect in Arkansas.
In order to fulfill obligations under CAA section 111(d), the
Arkansas Department of Energy and Environment, Division of
Environmental Quality (ADEQ) submitted a state plan for the control of
emissions from existing MSW landfills for the State of Arkansas on June
20, 2022, and supplemented its submittal on August 24, 2022, and August
31, 2022.\1\ The Arkansas MSW landfills plan implements and enforces
the applicable provisions under the MSW landfills EG at 40 CFR part 60,
subpart Cf, and additionally meets the relevant requirements of the CAA
section 111(d) implementing regulations at 40 CFR part 60, subpart B.
The Arkansas submittal and the supplements are included in the public
docket for this rulemaking (Docket No. EPA-R06-OAR-2022-0546).
---------------------------------------------------------------------------
\1\ The Arkansas plan submitted by ADEQ does not cover sources
located in Indian country.
---------------------------------------------------------------------------
II. Evaluation
The EPA has evaluated the Arkansas MSW landfills plan to determine
whether the plan meets applicable requirements from the MSW landfills
EG at 40 CFR part 60, subpart Cf, and the CAA section 111(d)
implementing regulations at 40 CFR part 60, subpart B. The EPA's
detailed rationale and discussion on the Arkansas MSW landfills plan
can be found in the EPA Technical Support Document (TSD), located in
the docket for this rulemaking.
The Arkansas state plan submittal package includes all materials
necessary to be deemed administratively and technically complete
according to the criteria of 40 CFR part 60, subpart B. The state plan
document (the ``Arkansas State Plan for 111(d) Designated Facilities'')
includes all the necessary authority for the implementation and
enforcement of the MSW landfill Emission Guidelines in the State.
Specifically, the State appropriately incorporated all applicable EG
requirements from 40 CFR part 60, subpart Cf, into the Arkansas
Pollution Control and Ecology Commission (APC&EC) Rule 19, Chapter 17.
Both the adopted state plan document and the relevant APC&EC
regulations, as well as all other relevant plan submittal materials may
be found in the docket for this action. Necessary State legal and
enforcement authorities required for plan approval are located
elsewhere in Arkansas's statute, rules and regulations and have been
reviewed and approved of by the EPA in the course of prior state
implementation plan as well as section 111(d) and/or 129 state plan
approvals. See 40 CFR part 52, subpart E, and 40 CFR part 62, subpart
E.
The Arkansas MSW landfills plan has been evaluated in detail in the
TSD. Our evaluation demonstrates that the Arkansas MSW landfills plan
meets the requirements in 40 CFR part 60, subpart Cf and subpart B, and
is consistent with the requirements for an approvable section 111(d)
state plans for MSW landfills.
III. Proposed Action
The EPA is proposing to approve the Arkansas MSW landfill plan
submitted by ADEQ in accordance with the requirements of section 111(d)
of the CAA and to amend 40 CFR part 62, subpart E, to codify EPA's
approval. The EPA is proposing to find that the Arkansas MSW landfill
plan is at least as protective as the Federal requirements provided
under the MSW landfills EG, codified at 40 CFR part 60, subpart Cf.
Once approved by the EPA, the Arkansas MSW landfills plan will become
federally enforceable.
IV. Environmental Justice Considerations
Executive Order 12898 (Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations, 59 FR 7629,
Feb. 16, 1994) directs federal agencies to identify and address
``disproportionately high and adverse human health or environmental
effects'' of their actions on minority populations and low-income
populations to the greatest extent practicable and permitted by law.
The 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.'' \2\ EPA is providing
additional analysis of environmental justice associated with this
action. We are doing so for the purpose of providing information to the
public, not as a basis of our proposed action.
---------------------------------------------------------------------------
\2\ See <a href="https://www.epa.gov/environmentaljustice/learn-about-environmental-justice">https://www.epa.gov/environmentaljustice/learn-about-environmental-justice</a>.
---------------------------------------------------------------------------
EPA conducted screening analyses using EJSCREEN, an environmental
justice mapping and screening tool that provides EPA with a nationally
consistent dataset and approach for combining various environmental and
demographic indicators.\3\ The EJSCREEN tool presents these indicators
at a Census block group (CBG) level or a larger user-specified
``buffer'' area that covers multiple CBGs.\4\ An individual CBG is a
cluster of contiguous blocks within the same census tract and generally
contains between 600 and 3,000 people. EJSCREEN is not a tool for
performing in-depth risk analysis, but is instead a screening tool that
provides an initial representation of indicators related to
environmental justice and is subject to uncertainty in some underlying
data (e.g., some environmental indicators are based on monitoring data
which are not uniformly available; others are based on self-reported
data).\5\ To help mitigate this uncertainty, we have summarized
EJSCREEN data within larger ``buffer'' areas covering multiple block
groups and representing the average resident within the buffer areas
surrounding the MSW landfills. We present EJSCREEN environmental
indicators to help screen for locations where residents may experience
a higher overall pollution burden than would be expected for a block
group with the same total population. These indicators of overall
pollution burden include estimates of ambient particulate matter
(PM<INF>2.5</INF>) and ozone concentration, a score for traffic
proximity and volume, percentage of pre-1960 housing units (lead paint
indicator), and scores for proximity to Superfund sites, risk
management plan
---------------------------------------------------------------------------
\3\ The EJSCREEN tool is available at <a href="https://www.epa.gov/ejscreen">https://www.epa.gov/ejscreen</a>.
\4\ See <a href="https://www.census.gov/programs-surveys/geography/about/glossary.html">https://www.census.gov/programs-surveys/geography/about/glossary.html</a>.
\5\ In addition, EJSCREEN relies on the five-year block group
estimates from the U.S. Census American Community Survey. The
advantage of using five-year over single-year estimates is increased
statistical reliability of the data (i.e., lower sampling error),
particularly for small geographic areas and population groups. For
more information, see <a href="https://www.census.gov/content/dam/Census/library/publications/2020/acs/acs_general_handbook_2020.pdf">https://www.census.gov/content/dam/Census/library/publications/2020/acs/acs_general_handbook_2020.pdf</a>.

(RMP) sites, and hazardous waste facilities.\6\ EJSCREEN also provides
information on demographic indicators, including percent low-income,
communities of color, linguistic isolation, and less than high school
education. The EPA prepared EJSCREEN reports covering buffer areas of
approximately 3-mile radii around the existing MSW landfills in
Arkansas. Table 1 presents a summary of results from the EPA's
screening-level analysis for the areas surrounding each MSW landfill
compared to the U.S. as a whole, where the landfill was located in an
area where one or more of the EJ indices were greater than the 80th
percentiles (the full, detailed EJSCREEN reports are provided in the
docket for this rulemaking).

This proposed rule is proposing to approve Arkansas's MSW Landfills
Plan, received on June 20, 2022, in accordance with section 111(d) of
the CAA. The Arkansas MSW Landfills Plan incorporates federal
requirements for MSW landfills, as specified in the MSW landfills EG at
40 CFR part 60, subpart Cf, which are also implemented under the MSW
Landfills Federal Plan at 40 CFR part 62, subpart OOO. The MSW
Landfills Federal Plan was implemented by EPA in Arkansas as Arkansas
did not have an approved MSW landfills plan addressing applicable EG
requirements. These EG requirements implemented under the MSW Landfills
Federal Plan and now incorporated by Arkansas in its MSW landfills plan
is designed to result in significant emissions reductions for MSW
landfills, as described in the Federal Registers for the MSW landfill
rules (80 FR 52100; 81 FR 59276). Landfill gas is a natural byproduct
of the decomposition of organic material in landfills and is composed
of roughly 50% methane, 50% carbon dioxide (CO<INF>2</INF>), and less
than 1% non-methane organic compounds (NMOC) by volume, which include
volatile organic
[[Page 59379]]
compounds (VOC) and various organic hazardous air pollutants (HAP).\7\
VOC emissions are precursors to both fine particulate matter
(PM<INF>2.5</INF>) and ozone formation; exposure to PM<INF>2.5</INF>
and ozone is associated with significant public health effects,
including (1) cardiovascular morbidity such as heart attacks, (2)
respiratory morbidity such as asthma attacks, acute bronchitis, (3)
hospital admissions and emergency room visits, and (4) premature
mortality.\8\ Hazardous air pollutants may cause cancer or other
serious health effects, such as reproductive effects or birth
defects.\9\ In addition, methane is a potent greenhouse gas with a
global warming potential 28-36 times greater than CO<INF>2.</INF>
Therefore, we believe that these requirements for existing MSW
landfills and resulting emissions reductions have climate benefits and
have contributed to reduced environmental and health impacts on all
populations impacted by emissions from these sources in Arkansas,
including people of color and low-income populations, and will continue
to do so under Federal oversight. This proposed rule is not anticipated
to have disproportionately high or adverse human health or
environmental effects on communities with environmental justice
concerns because it is not anticipated to result in or contribute to
emissions increases in Arkansas. If finalized as proposed, EPA's
approval of the Arkansas MSW Landfills Plan will make the Plan and the
corresponding MSW landfills EG requirements incorporated into the Plan
federally enforceable by EPA as of the effective date of the final
rulemaking.

V. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a CAA
section 111(d) submission that complies with the provisions of the Act
and applicable Federal regulations. 42 U.S.C. 7411(d); 42 U.S.C. 7429;
40 CFR part 60, subparts B and Cf; and 40 CFR part 62, subpart A. Thus,
in reviewing CAA section 111(d) state plan submissions, EPA's role is
to approve state choices, provided that they meet the criteria of the
Act and implementing regulations. 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:
<bullet> 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);
<bullet> Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
<bullet> 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.);
<bullet> 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);
<bullet> Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
<bullet> Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
<bullet> Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
<bullet> 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
<bullet> Does not provide the 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 rule also does not have Tribal implications because
it will not have a substantial direct effect on one or more Indian
Tribes, on the relationship between the Federal Government and Indian
Tribes, or on the distribution of power and responsibilities between
the Federal Government and Indian Tribes, as specified by Executive
Order 13175 (65 FR 67249, November 9, 2000).
