New Jersey; Regional Haze State Implementation Plan for the Second
Implementation Period
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve the regional haze state implementation plan (SIP) revision
submitted by New Jersey on March 26, 2020, as satisfying applicable
requirements under the Clean Air Act (CAA) and EPA's Regional Haze Rule
for the program's second implementation period. New Jersey's SIP
submission addresses the requirement that states must periodically
revise their long-term strategies for making reasonable progress
towards the national goal of preventing any future, and remedying any
existing, anthropogenic impairment of visibility, including regional
haze, in mandatory Class I Federal areas. The SIP submission also
addresses other applicable requirements for the second implementation
period of the regional haze program. The EPA is taking this action
pursuant to sections 110 and 169A of the Clean Air Act.
DATES: Written comments must be received on or before September 19,
2022.

I. What action is the EPA proposing?
On March 26, 2020, supplemented on September 8, 2020, and April 1,
2021, the New Jersey Department of Environmental Protection (NJDEP)
submitted a revision to its SIP to address regional haze for the second
implementation period. NJDEP made this SIP submission to satisfy the
requirements of the CAA's regional haze program pursuant to CAA
sections 169A and 169B and 40 CFR 51.308. The EPA is proposing to find
that the New Jersey regional haze SIP submission for the second
implementation period meets the applicable statutory and regulatory
requirements and thus proposes to approve New Jersey's submission into
its SIP.
II. Background and Requirements for Regional Haze Plans
A. Regional Haze Background
In the 1977 CAA Amendments, Congress created a program for
protecting visibility in the nation's mandatory Class I Federal areas,
which include certain national parks and wilderness areas.\1\ CAA 169A.
The CAA establishes as a national goal the
[[Page 51017]]
``prevention of any future, and the remedying of any existing,
impairment of visibility in mandatory class I Federal areas which
impairment results from manmade air pollution.'' CAA 169A(a)(1). The
CAA further directs the EPA to promulgate regulations to assure
reasonable progress toward meeting this national goal. CAA 169A(a)(4).
On December 2, 1980, the EPA promulgated regulations to address
visibility impairment in mandatory Class I Federal areas (hereinafter
referred to as ``Class I areas'') that is ``reasonably attributable''
to a single source or small group of sources. (45 FR 80084, December 2,
1980). These regulations, codified at 40 CFR 51.300 through 51.307,
represented the first phase of the EPA's efforts to address visibility
impairment. In 1990, Congress added section 169B to the CAA to further
address visibility impairment, specifically, impairment from regional
haze. CAA 169B. The EPA promulgated the Regional Haze Rule (RHR),
codified at 40 CFR 51.308,\2\ on July 1, 1999. (64 FR 35714, July 1,
1999). These regional haze regulations are a central component of the
EPA's comprehensive visibility protection program for Class I areas.
---------------------------------------------------------------------------
\1\ Areas statutorily designated as mandatory Class I Federal
areas consist of national parks exceeding 6,000 acres, wilderness
areas and national memorial parks exceeding 5,000 acres, and all
international parks that were in existence on August 7, 1977. CAA
162(a). There are 156 mandatory Class I areas. The list of areas to
which the requirements of the visibility protection program apply is
in 40 CFR part 81, subpart D.
\2\ In addition to the generally applicable regional haze
provisions at 40 CFR 51.308, the EPA also promulgated regulations
specific to addressing regional haze visibility impairment in Class
I areas on the Colorado Plateau at 40 CFR 51.309. The latter
regulations are applicable only for specific jurisdictions' regional
haze plans submitted no later than December 17, 2007, and thus are
not relevant here.
---------------------------------------------------------------------------
Regional haze is visibility impairment that is produced by a
multitude of anthropogenic sources and activities which are located
across a broad geographic area and that emit pollutants that impair
visibility. Visibility impairing pollutants include fine and coarse
particulate matter (PM) (e.g., sulfates, nitrates, organic carbon,
elemental carbon, and soil dust) and their precursors (e.g., sulfur
dioxide (SO2), nitrogen oxides (NOX), and, in
some cases, volatile organic compounds (VOC) and ammonia
(NH3)). Fine particle precursors react in the atmosphere to
form fine particulate matter (PM2.5), which impairs
visibility by scattering and absorbing light. Visibility impairment
reduces the perception of clarity and color, as well as visible
distance.\3\
---------------------------------------------------------------------------
\3\ There are several ways to measure the amount of visibility
impairment, i.e., haze. One such measurement is the deciview, which
is the principal metric used by the RHR. Under many circumstances, a
change in one deciview will be perceived by the human eye to be the
same on both clear and hazy days. The deciview is unitless. It is
proportional to the logarithm of the atmospheric extinction of
light, which is the perceived dimming of light due to its being
scattered and absorbed as it passes through the atmosphere.
Atmospheric light extinction (b\ext\) is a metric used to for
expressing visibility and is measured in inverse megameters (Mm-1).
The EPA's Guidance on Regional Haze State Implementation Plans for
the Second Implementation Period (``2019 Guidance'') offers the
flexibility for the use of light extinction in certain cases. Light
extinction can be simpler to use in calculations than deciviews,
since it is not a logarithmic function. See, e.g., 2019 Guidance at
16, 19, https://www.epa.gov/visibility/guidance-regional-haze-state-implementation-plans-second-implementation-period, The EPA Office of
Air Quality Planning and Standards, Research Triangle Park (August
20, 2019). The formula for the deciview is 10 ln (b\ext\)/10 Mm-1).
40 CFR 51.301.
---------------------------------------------------------------------------
To address regional haze visibility impairment, the 1999 RHR
established an iterative planning process that requires both states in
which Class I areas are located and states ``the emissions from which
may reasonably be anticipated to cause or contribute to any impairment
of visibility'' in a Class I area to periodically submit SIP revisions
to address such impairment. CAA 169A(b)(2); \4\ see also 40 CFR
51.308(b), (f) (establishing submission dates for iterative regional
haze SIP revisions); (64 FR at 35768, July 1, 1999). Under the CAA,
each SIP submission must contain ``a long-term (ten to fifteen years)
strategy for making reasonable progress toward meeting the national
goal,'' CAA 169A(b)(2)(B); the initial round of SIP submissions also
had to address the statutory requirement that certain older, larger
sources of visibility impairing pollutants install and operate the best
available retrofit technology (BART). CAA 169A(b)(2)(A); 40 CFR
51.308(d), (e). States' first regional haze SIPs were due by December
17, 2007, 40 CFR 51.308(b), with subsequent SIP submissions containing
updated long-term strategies originally due July 31, 2018, and every
ten years thereafter. (64 FR at 35768, July 1, 1999). The EPA
established in the 1999 RHR that all states either have Class I areas
within their borders or ``contain sources whose emissions are
reasonably anticipated to contribute to regional haze in a Class I
area''; therefore, all states must submit regional haze SIPs.\5\ Id. at
35721.
---------------------------------------------------------------------------
\4\ The RHR expresses the statutory requirement for states to
submit plans addressing out-of-state class I areas by providing that
states must address visibility impairment ``in each mandatory Class
I Federal area located outside the State that may be affected by
emissions from within the State.'' 40 CFR 51.308(d), (f).
\5\ In addition to each of the fifty states, the EPA also
concluded that the Virgin Islands and District of Columbia must also
submit regional haze SIPs because they either contain a Class I area
or contain sources whose emissions are reasonably anticipated to
contribute regional haze in a Class I area. See 40 CFR 51.300(b),
(d)(3).
---------------------------------------------------------------------------
Much of the focus in the first implementation period of the
regional haze program, which ran from 2007 through 2018, was on
satisfying states' BART obligations. First implementation period SIPs
were additionally required to contain long-term strategies for making
reasonable progress toward the national visibility goal, of which BART
is one component. The core required elements for the first
implementation period SIPs (other than BART) are laid out in 40 CFR
51.308(d). Those provisions required that states containing Class I
areas establish reasonable progress goals (RPGs) that are measured in
deciviews and reflect the anticipated visibility conditions at the end
of the implementation period including from implementation of states'
long-term strategies. The first planning period RPGs were required to
provide for an improvement in visibility for the most impaired days
over the period of the implementation plan and ensure no degradation in
visibility for the least impaired days over the same period. In
establishing the RPGs for any Class I area in a state, the state was
required to consider four statutory factors: the costs of compliance,
the time necessary for compliance, the energy and non-air quality
environmental impacts of compliance, and the remaining useful life of
any potentially affected sources. CAA 169A(g)(1); 40 CFR 51.308(d)(1).
States were also required to calculate baseline (using the five
year period of 2000-2004) and natural visibility conditions (i.e.,
visibility conditions without anthropogenic visibility impairment) for
each Class I area, and to calculate the linear rate of progress needed
to attain natural visibility conditions, assuming a starting point of
baseline visibility conditions in 2004 and ending with natural
conditions in 2064. This linear interpolation is known as the uniform
rate of progress (URP) and is used as a tracking metric to help states
assess the amount of progress they are making towards the national
visibility goal over time in each Class I area.\6\ 40 CFR
51.308(d)(1)(i)(B), (d)(2).
[[Page 51018]]
The 1999 RHR also provided that States' long-term strategies must
include the ``enforceable emissions limitations, compliance, schedules,
and other measures as necessary to achieve the reasonable progress
goals.'' 40 CFR 51.308(d)(3). In establishing their long-term
strategies, states are required to consult with other states that also
contribute to visibility impairment in a given Class I area and include
all measures necessary to obtain their shares of the emission
reductions needed to meet the RPGs. 40 CFR 51.308(d)(3)(i), (ii).
Section 51.308(d) also contains seven additional factors states must
consider in formulating their long-term strategies, 40 CFR
51.308(d)(3)(v), as well as provisions governing monitoring and other
implementation plan requirements. 40 CFR 51.308(d)(4). Finally, the
1999 RHR required states to submit periodic progress reports--SIP
revisions due every five years that contain information on states'
implementation of their regional haze plans and an assessment of
whether anything additional is needed to make reasonable progress, see
40 CFR 51.308(g), (h)--and to consult with the Federal Land Manager(s)
\7\ (FLMs) responsible for each Class I area according to the
requirements in CAA 169A(d) and 40 CFR 51.308(i).
---------------------------------------------------------------------------
\6\ EPA established the URP framework in the 1999 RHR to provide
``an equitable analytical approach'' to assessing the rate of
visibility improvement at Class I areas across the country. The
start point for the URP analysis is 2004 and the endpoint was
calculated based on the amount of visibility improvement that was
anticipated to result from implementation of existing CAA programs
over the period from the mid-1990s to approximately 2005. Assuming
this rate of progress would continue into the future, EPA determined
that natural visibility conditions would be reached in 60 years, or
2064 (60 years from the baseline starting point of 2004). However,
EPA did not establish 2064 as the year by which the national goal
must be reached. 64 FR at 35731-32. That is, the URP and the 2064
date are not enforceable targets, but are rather tools that ``allow
for analytical comparisons between the rate of progress that would
be achieved by the state's chosen set of control measures and the
URP.'' (82 FR 3078, 3084, January 10, 2017).
\7\ The EPA's regulations define ``Federal Land Manager'' as
``the Secretary of the department with authority over the Federal
Class I area (or the Secretary's designee) or, with respect to
Roosevelt-Campobello International Park, the Chairman of the
Roosevelt-Campobello International Park Commission.'' 40 CFR 51.301.
---------------------------------------------------------------------------
On January 10, 2017, the EPA promulgated revisions to the RHR, (82
FR 3078, January 10, 2017), that apply for the second and subsequent
implementation periods. The 2017 rulemaking made several changes to the
requirements for regional haze SIPs to clarify States' obligations and
streamline certain regional haze requirements. The revisions to the
regional haze program for the second and subsequent implementation
periods focused on the requirement that States' SIPs contain long-term
strategies for making reasonable progress towards the national
visibility goal. The reasonable progress requirements as revised in the
2017 rulemaking (referred to here as the 2017 RHR Revisions) are
codified at 40 CFR 51.308(f). Among other changes, the 2017 RHR
Revisions adjusted the deadline for States to submit their second
implementation period SIPs from July 31, 2018, to July 31, 2021,
clarified the order of analysis and the relationship between RPGs and
the long-term strategy, and focused on making visibility improvements
on the days with the most anthropogenic visibility impairment, as
opposed to the days with the most visibility impairment overall. The
EPA also revised requirements of the visibility protection program
related to periodic progress reports and FLM consultation. The specific
requirements applicable to second implementation period regional haze
SIP submissions are addressed in detail below.
The EPA provided guidance to the states for their second
implementation period SIP submissions in the preamble to the 2017 RHR
Revisions as well as in subsequent, stand-alone guidance documents. In
August 2019, the EPA issued ``Guidance on Regional Haze State
Implementation Plans for the Second Implementation Period'' (``2019
Guidance'').\8\ On July 8, 2021, the EPA issued a memorandum containing
``Clarifications Regarding Regional Haze State Implementation Plans for
the Second Implementation Period'' (``2021 Clarifications Memo'').\9\
Additionally, the EPA further clarified the recommended procedures for
processing ambient visibility data and optionally adjusting the URP to
account for international anthropogenic and prescribed fire impacts in
two technical guidance documents: the December 2018 ``Technical
Guidance on Tracking Visibility Progress for the Second Implementation
Period of the Regional Haze Program'' (``2018 Visibility Tracking
Guidance''),\10\ and the June 2020 ``Recommendation for the Use of
Patched and Substituted Data and Clarification of Data Completeness for
Tracking Visibility Progress for the Second Implementation Period of
the Regional Haze Program'' and associated Technical Addendum (``2020
Data Completeness Memo'').\11\

---------------------------------------------------------------------------
As previously explained in the 2021 Clarifications Memo, EPA
intends the second implementation period of the regional haze program
to secure meaningful reductions in visibility impairing pollutants that
build on the significant progress states have achieved to date. The
Agency also recognizes that analyses regarding reasonable progress are
state-specific and that, based on states' and sources' individual
circumstances, what constitutes reasonable reductions in visibility
impairing pollutants will vary from state-to-state. While there exist
many opportunities for states to leverage both ongoing and upcoming
emission reductions under other CAA programs, the Agency expects states
to undertake rigorous reasonable progress analyses that identify
further opportunities to advance the national visibility goal
consistent with the statutory and regulatory requirements. See
generally 2021 Clarifications Memo. This is consistent with Congress's
determination that a visibility protection program is needed in
addition to the CAA's National Ambient Air Quality Standards and
Prevention of Significant Deterioration programs, as further emission
reductions may be necessary to adequately protect visibility in Class I
areas throughout the country.\12\
---------------------------------------------------------------------------
\12\ See, e.g., H.R. Rep No. 95-294 at 205 (``In determining how
to best remedy the growing visibility problem in these areas of
great scenic importance, the committee realizes that as a matter of
equity, the national ambient air quality standards cannot be revised
to adequately protect visibility in all areas of the country.''),
(``the mandatory class I increments of [the PSD program] do not
adequately protect visibility in class I areas'').
---------------------------------------------------------------------------
B. Roles of Agencies in Addressing Regional Haze
Because the air pollutants and pollution affecting visibility in
Class I areas can be transported over long distances, successful
implementation of the regional haze program requires long-term,
regional coordination among multiple jurisdictions and agencies that
have responsibility for Class I areas and the emissions that impact
visibility in those areas. In order to address regional haze, states
need to develop strategies in coordination with one another,
considering the effect of emissions from
[[Page 51019]]
one jurisdiction on the air quality in another. Five regional planning
organizations (RPOs),\13\ which include representation from state and
tribal governments, the EPA, and FLMs, were developed in the lead-up to
the first implementation period to address regional haze. RPOs evaluate
technical information to better understand how emissions from State and
Tribal land impact Class I areas across the country, pursue the
development of regional strategies to reduce emissions of particulate
matter and other pollutants leading to regional haze, and help states
meet the consultation requirements of the RHR.
---------------------------------------------------------------------------
\13\ RPOs are sometimes also referred to as ``multi-
jurisdictional organizations,'' or MJOs. For the purposes of this
notice, the terms RPO and MJO are synonymous.
---------------------------------------------------------------------------
The Mid-Atlantic/Northeast Visibility Union (MANE-VU), one of the
five RPOs described above, is a collaborative effort of state
governments, tribal governments, and various Federal agencies
established to initiate and coordinate activities associated with the
management of regional haze, visibility, and other air quality issues
in the Mid-Atlantic and Northeast corridor of the United States. Member
states and tribal governments (listed alphabetically) include:
Connecticut, Delaware, the District of Columbia, Maine, Maryland,
Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania,
Penobscot Indian Nation, Rhode Island, St. Regis Mohawk Tribe, and
Vermont. The Federal partner members of MANE-VU are EPA, U.S. National
Parks Service (NPS), U.S. Fish and Wildlife Service (FWS), and U.S.
Forest Service (USFS).
III. Requirements for Regional Haze Plans for the Second Implementation
Period
Under the CAA and EPA's regulations, all 50 states, the District of
Columbia, and the U.S. Virgin Islands are required to submit regional
haze SIPs satisfying the applicable requirements for the second
implementation period of the regional haze program by July 31, 2021.
Each state's SIP must contain a long-term strategy for making
reasonable progress toward meeting the national goal of remedying any
existing and preventing any future anthropogenic visibility impairment
in Class I areas. CAA 169A(b)(2)(B). To this end, Sec. 51.308(f) lays
out the process by which states determine what constitutes their long-
term strategies, with the order of the requirements in Sec.
51.308(f)(1) through (f)(3) generally mirroring the order of the steps
in the reasonable progress analysis \14\ and (f)(4) through (f)(6)
containing additional, related requirements. Broadly speaking, a state
first must identify the Class I areas within the state and determine
the Class I areas outside the state in which visibility may be affected
by emissions from the state. These are the Class I areas that must be
addressed in the state's long-term strategy. See 40 CFR 51.308(f),
(f)(2). For each Class I area within its borders, a state must then
calculate the baseline, current, and natural visibility conditions for
that area, as well as the visibility improvement made to date and the
URP. See 40 CFR 51.308(f)(1). Each state having a Class I area and/or
emissions that may affect visibility in a Class I area must then
develop a long-term strategy that includes the enforceable emission
limitations, compliance schedules, and other measures that are
necessary to make reasonable progress in such areas. Reasonable
progress is determined by applying the four factors in CAA section
169A(g)(1) to sources of visibility-impairing pollutants that the state
has selected to assess for controls for the second implementation
period. See 40 CFR 51.308(f)(2). A state evaluates potential emission
reduction measures for those selected sources and determines which are
necessary to make reasonable progress using the four statutory factors.
Those measures are then incorporated into the state's long-term
strategy. After a state has developed its long-term strategy, it then
establishes RPGs for each Class I area within its borders by modeling
the visibility impacts of all reasonable progress controls at the end
of the second implementation period, i.e., in 2028, as well as the
impacts of other requirements of the CAA. The RPGs include reasonable
progress controls not only for sources in the state in which the Class
I area is located, but also for sources in other states that contribute
to visibility impairment in that area. The RPGs are then compared to
the baseline visibility conditions and the URP to ensure that progress
is being made towards the statutory goal of preventing any future and
remedying any existing anthropogenic visibility impairment in Class I
areas. 40 CFR 51.308(f)(2)-(3).
---------------------------------------------------------------------------
\14\ EPA explained in the 2017 RHR Revisions that we were
adopting new regulatory language in 40 CFR 51.308(f) that, unlike
the structure in 51.308(d), ``tracked the actual planning
sequence.'' (82 FR 3091, January 10, 2017).
---------------------------------------------------------------------------
In addition to satisfying the requirements at 40 CFR 51.308(f)
related to reasonable progress, the SIP submissions due by July 31,
2021, for the second implementation period must address the
requirements in Sec. 51.308(g)(1) through (5) pertaining to periodic
reports describing progress towards the RPGs, 40 CFR 51.308(f)(5), as
well as requirements for FLM consultation that apply to all visibility
protection SIPs and SIP revisions. 40 CFR 51.308(i).
A state must submit its regional haze SIP and subsequent SIP
revisions to the EPA according to the requirements applicable to all
SIP revisions under the CAA and EPA's regulations. See CAA 169(b)(2);
CAA 110(a). Upon EPA approval, a SIP is enforceable by the Agency and
the public under the CAA. If EPA finds that a state fails to make a
required SIP revision, or if the EPA finds that a state's SIP is
incomplete or if disapproves the SIP, the Agency must promulgate a
federal implementation plan (FIP) that satisfies the applicable
requirements. CAA 110(c)(1).
A. Identification of Class I Areas
The SIP revision submission due by July 31, 2021, ``must address
regional haze in each mandatory Class I Federal area located within the
State and in each mandatory Class I Federal area located outside the
State that may be affected by emissions from within the State.'' 40 CFR
51.308(f); see also 51.308(f)(2).\15\ Thus, the first step in
developing a regional haze SIP is for a state to determine which Class
I areas, in addition to those within its borders, ``may be affected''
by emissions from within the state. In the 1999 RHR, the EPA determined
that all states contribute to visibility impairment in at least one
Class I area, 64 FR at 35720-22, and explained that the statute and
regulations lay out an ``extremely low triggering threshold'' for
determining ``whether States should be required to engage in air
quality planning and analysis as a prerequisite to determining the need
for control of emissions from sources within their State.'' Id. at
35721.
---------------------------------------------------------------------------
\15\ The RHR uses the phrase ``that may be affected by emissions
from the State'' to implement CAA 169A(b)(2)'s requirement that a
state ``the emissions from which may reasonably be anticipated to
cause or contribute to any impairment of visibility'' submit a SIP.
---------------------------------------------------------------------------
A state must determine which Class I areas must be addressed by its
SIP by evaluating the total emissions of visibility impairing
pollutants from all sources within the state. While the RHR does not
require this evaluation to be conducted in any particular manner, EPA's
2019 Guidance provides recommendations for how such an assessment might
be accomplished, including by, where appropriate, using the
determinations previously made for the first implementation period.
2019
[[Page 51020]]
Guidance at 8-9. In addition, the determination of which Class I areas
may be affected by a state's emissions is subject to the requirement in
40 CFR 51.308(f)(2)(iii) to ``document the technical basis, including
modeling, monitoring, cost, engineering, and emissions information, on
which the State is relying to determine the emission reduction measures
that are necessary to make reasonable progress in each mandatory Class
I Federal area it affects.''
B. Calculations of Baseline, Current, and Natural Visibility
Conditions; Progress to Date; and the Uniform Rate of Progress
As part of assessing whether a SIP submission for the second
implementation period is providing for reasonable progress towards the
national visibility goal, the RHR contains requirements in Sec.
51.308(f)(1) related to tracking visibility improvement over time. The
requirements of this subsection apply only to states having Class I
areas within their borders; the required calculations must be made for
each such Class I area. EPA's 2018 Visibility Tracking Guidance \16\
provides recommendations to assist states in satisfying their
obligations under Sec. 51.308(f)(1); specifically, in developing
information on baseline, current, and natural visibility conditions,
and in making optional adjustments to the URP to account for the
impacts of international anthropogenic emissions and prescribed fires.
See 82 FR at 3103-05.
---------------------------------------------------------------------------
\16\ The 2018 Visibility Tracking Guidance references and relies
on parts of the 2003 Tracking Guidance: ``Guidance for Tracking
Progress Under the Regional Haze Rule,'' which can be found at
https://www3.epa.gov/ttnamti1/files/ambient/visible/tracking.pdf.
---------------------------------------------------------------------------
The RHR requires tracking of visibility conditions on two sets of
days: the clearest and the most impaired days. Visibility conditions
for both sets of days are expressed as the average deciview index for
the relevant five-year period (the period representing baseline or
current visibility conditions). The RHR provides that the relevant sets
of days for visibility tracking purposes are the 20% clearest (the 20%
of monitored days in a calendar year with the lowest values of the
deciview index) and 20% most impaired days (the 20% of monitored days
in a calendar year with the highest amounts of anthropogenic visibility
impairment).\17\ 40 CFR 51.301. A state must calculate visibility
conditions for both the 20% clearest and 20% most impaired days for the
baseline period of 2000-2004 and the most recent five-year period for
which visibility monitoring data are available (representing current
visibility conditions). 40 CFR 51.308(f)(1)(i), (iii). States must also
calculate natural visibility conditions for the clearest and most
impaired days,\18\ by estimating the conditions that would exist on
those two sets of days absent anthropogenic visibility impairment. 40
CFR 51.308(f)(1)(ii). Using all these data, states must then calculate,
for each Class I area, the amount of progress made since the baseline
period (2000-2004) and how much improvement is left to achieve in order
to reach natural visibility conditions.
---------------------------------------------------------------------------
\17\ This notice also refers to the 20% clearest and 20% most
anthropogenically impaired days as the ``clearest'' and ``most
impaired'' or ``most anthropogenically impaired'' days,
respectively.
\18\ The RHR at 40 CFR 51.308(f)(1)(ii) contains an error
related to the requirement for calculating two sets of natural
conditions values. The rule says ``most impaired days or the
clearest days'' where it should say ``most impaired days and
clearest days.'' This is an error that was intended to be corrected
in the 2017 RHR Revisions but did not get corrected in the final
rule language. This is supported by the preamble text at 82 FR 3098:
``In the final version of 40 CFR 51.308(f)(1)(ii), an occurrence of
``or'' has been corrected to ``and'' to indicate that natural
visibility conditions for both the most impaired days and the
clearest days must be based on available monitoring information.''
---------------------------------------------------------------------------
Using the data for the set of most impaired days only, states must
plot a line between visibility conditions in the baseline period and
natural visibility conditions for each Class I area to determine the
URP--the amount of visibility improvement, measured in deciviews, that
would need to be achieved during each implementation period in order to
achieve natural visibility conditions by the end of 2064. The URP is
used in later steps of the reasonable progress analysis for
informational purposes and to provide a non-enforceable benchmark
against which to assess a Class I area's rate of visibility
improvement.\19\ Additionally, in the 2017 RHR Revisions, the EPA
provided states the option of proposing to adjust the endpoint of the
URP to account for impacts of anthropogenic sources outside the United
States and/or impacts of certain types of wildland prescribed fires.
These adjustments, which must be approved by the EPA, are intended to
avoid any perception that states should compensate for impacts from
international anthropogenic sources and to give states the flexibility
to determine that limiting the use of wildland-prescribed fire is not
necessary for reasonable progress. 82 FR 3107 footnote 116.
---------------------------------------------------------------------------
\19\ Being on or below the URP is not a ``safe harbor''; i.e.,
achieving the URP does not mean that a Class I area is making
``reasonable progress'' and does not relieve a state from using the
four statutory factors to determine what level of control is needed
to achieve such progress. See, e.g., 82 FR at 3093.
---------------------------------------------------------------------------
EPA's 2018 Visibility Tracking Guidance can be used to help satisfy
the 40 CFR 51.308(f)(1) requirements, including in developing
information on baseline, current, and natural visibility conditions,
and in making optional adjustments to the URP. In addition, the 2020
Data Completeness Memo provides recommendations on the data
completeness language referenced in Sec. 51.308(f)(1)(i) and provides
updated natural conditions estimates for each Class I area.
C. Long-Term Strategy for Regional Haze
The core component of a regional haze SIP submission is a long-term
strategy that addresses regional haze in each Class I area within a
state's borders and each Class I area that may be affected by emissions
from the state. The long-term strategy ``must include the enforceable
emissions limitations, compliance schedules, and other measures that
are necessary to make reasonable progress, as determined pursuant to
(f)(2)(i) through (iv).'' 40 CFR 51.308(f)(2). The amount of progress
that is ``reasonable progress'' is determined by applying the four
statutory factors in CAA section 169A(g)(1) in an evaluation of
potential control options for sources of visibility impairing
pollutants, which is referred to as a ``four-factor'' analysis. The
outcome of that analysis is the emission reduction measures that a
particular source or group of sources needs to implement in order to
make reasonable progress towards the national visibility goal. See 40
CFR 51.308(f)(2)(i). Emission reduction measures that are necessary to
make reasonable progress may be either new, additional control measures
for a source, or they may be the existing emission reduction measures
that a source is already implementing. See 2019 Guidance at 43; 2021
Clarifications Memo at 8-10. Such measures must be represented by
``enforceable emissions limitations, compliance schedules, and other
measures'' (i.e., any additional compliance tools) in a state's long-
term strategy in its SIP. 40 CFR 51.308(f)(2).
Section 51.308(f)(2)(i) provides the requirements for the four-
factor analysis. The first step of this analysis entails selecting the
sources to be evaluated for emission reduction measures; to this end,
the RHR requires states to consider ``major and minor stationary
sources or groups of sources, mobile sources, and area sources'' of
visibility impairing pollutants for potential four-factor control
analysis. 40
[[Page 51021]]
CFR 51.308(f)(2)(i). A threshold question at this step is which
visibility impairing pollutants will be analyzed. As EPA previously
explained, consistent with the first implementation period, EPA
generally expects that each state will analyze at least SO2
and NOX in selecting sources and determining control
measures. See 2019 Guidance at 12, 2021 Clarifications Memo at 4. A
state that chooses not to consider at least these two pollutants should
demonstrate why such consideration would be unreasonable. 2021
Clarifications Memo at 4.
While states have the option to analyze all sources, the 2019
Guidance explains that ``an analysis of control measures is not
required for every source in each implementation period,'' and that
``[s]electing a set of sources for analysis of control measures in each
implementation period is . . . consistent with the Regional Haze Rule,
which sets up an iterative planning process and anticipates that a
state may not need to analyze control measures for all its sources in a
given SIP revision.'' 2019 Guidance at 9. However, given that source
selection is the basis of all subsequent control determinations, a
reasonable source selection process ``should be designed and conducted
to ensure that source selection results in a set of pollutants and
sources the evaluation of which has the potential to meaningfully
reduce their contributions to visibility impairment.'' 2021
Clarifications Memo at 3.
EPA explained in the 2021 Clarifications Memo that each state has
an obligation to submit a long-term strategy that addresses the
regional haze visibility impairment that results from emissions from
within that state. Thus, source selection should focus on the in-state
contribution to visibility impairment and be designed to capture a
meaningful portion of the state's total contribution to visibility
impairment in Class I areas. A state should not decline to select its
largest in-state sources on the basis that there are even larger out-
of-state contributors. 2021 Clarifications Memo at 4.\20\
---------------------------------------------------------------------------
\20\ Similarly, in responding to comments on the 2017 RHR
Revisions EPA explained that ``[a] state should not fail to address
its many relatively low-impact sources merely because it only has
such sources and another state has even more low-impact sources and/
or some high impact sources.'' Responses to Comments on Protection
of Visibility: Amendments to Requirements for State Plans; Proposed
Rule (81 FR 26942, May 4, 2016) at 87-88.
---------------------------------------------------------------------------
Thus, while states have discretion to choose any source selection
methodology that is reasonable, whatever choices they make should be
reasonably explained and result in a set of sources which capture a
meaningful portion of the state's total contribution to visibility
impairment. To this end, 40 CFR 51.308(f)(2)(i) requires that a state's
SIP submission include ``a description of the criteria it used to
determine which sources or groups of sources it evaluated.'' The
technical basis for source selection, which may include methods for
quantifying potential visibility impacts such as emissions divided by
distance metrics, trajectory analyses, residence time analyses, and/or
photochemical modeling, must also be appropriately documented, as
required by 40 CFR 51.308(f)(2)(iii).
Once a state has selected the set of sources, the next step is to
determine the emissions reduction measures for those sources that are
necessary to make reasonable progress for the second implementation
period.\21\ This is accomplished by considering the four factors--``the
costs of compliance, the time necessary for compliance, and the energy
and nonair quality environmental impacts of compliance, and the
remaining useful life of any existing source subject to such
requirements.'' CAA 169A(g)(1). The EPA has explained that the four-
factor analysis is an assessment of potential emission reduction
measures (i.e., control options) for sources; ``use of the terms
`compliance' and `subject to such requirements' in section 169A(g)(1)
strongly indicates that Congress intended the relevant determination to
be the requirements with which sources would have to comply in order to
satisfy the CAA's reasonable progress mandate.'' 82 FR at 3091. Thus,
for each source it has selected for four-factor analysis,\22\ a state
must consider a ``meaningful set'' of technically feasible control
options for reducing emissions of visibility impairing pollutants. Id.
at 3088. The 2019 Guidance provides that ``[a] state must reasonably
pick and justify the measures that it will consider, recognizing that
there is no statutory or regulatory requirement to consider all
technically feasible measures or any particular measures. A range of
technically feasible measures available to reduce emissions would be
one way to justify a reasonable set.'' 2019 Guidance at 29.
---------------------------------------------------------------------------
\21\ The CAA provides that, ``[i]n determining reasonable
progress there shall be taken into consideration'' the four
statutory factors. CAA 169A(g)(1). However, in addition to four-
factor analyses for selected sources, groups of sources, or source
categories, a state may also consider additional emission reduction
measures for inclusion in its long-term strategy, e.g., from other
newly adopted, on-the-books, or on-the-way rules and measures for
sources not selected for four-factor analysis for the second
planning period.
\22\ ``Each source'' or ``particular source'' is used here as
shorthand. While a source-specific analysis is one way of applying
the four factors, neither the statute nor the RHR requires states to
evaluate individual sources. Rather, states have ``the flexibility
to conduct four-factor analyses for specific sources, groups of
sources or even entire source categories, depending on state policy
preferences and the specific circumstances of each state.'' 82 FR at
3088. However, not all approaches to grouping sources for four-
factor analysis are necessarily reasonable; the reasonableness of
grouping sources in any particular instance will depend on the
circumstances and the manner in which grouping is conducted. If it
is feasible to establish and enforce different requirements for
sources or subgroups of sources, and if relevant factors can be
quantified for those sources or subgroups, then states should make a
separate reasonable progress determination for each source or
subgroup. 2021 Clarifications Memo at 7-8.
---------------------------------------------------------------------------
EPA's 2021 Clarifications Memo provides further guidance on what
constitutes a reasonable set of control options for consideration: ``A
reasonable four-factor analysis will consider the full range of
potentially reasonable options for reducing emissions.'' 2021
Clarifications Memo at 7. In addition to add-on controls and other
retrofits (i.e., new emission reduction measures for sources), EPA
explained that states should generally analyze efficiency improvements
for sources' existing measures as control options in their four-factor
analyses, as in many cases such improvements are reasonable given that
they typically involve only additional operation and maintenance costs.
Additionally, the 2021 Clarifications Memo provides that states that
have assumed a higher emission rate than a source has achieved or could
potentially achieve using its existing measures should also consider
lower emission rates as potential control options. That is, a state
should consider a source's recent actual and projected emission rates
to determine if it could reasonably attain lower emission rates with
its existing measures. If so, the state should analyze the lower
emission rate as a control option for reducing emissions. 2021
Clarifications Memo at 7. The EPA's recommendations to analyze
potential efficiency improvements and achievable lower emission rates
apply to both sources that have been selected for four-factor analysis
and those that have forgone a four-factor analysis on the basis of
existing ``effective controls.'' See 2021 Clarifications Memo at 5, 10.
After identifying a reasonable set of potential control options for
the sources it has selected, a state then collects information on the
four factors with regard to each option identified. The EPA has also
explained that, in addition to the four statutory factors, states have
flexibility under the CAA and RHR to reasonably consider visibility
benefits as
[[Page 51022]]
an optional fifth factor alongside the four statutory factors.\23\ The
2019 Guidance provides recommendations for the types of information
that can be used to characterize the four factors (with or without
visibility), as well as ways in which states might reasonably consider
and balance that information to determine which of the potential
control options is necessary to make reasonable progress. See 2019
Guidance at 30-36. The 2021 Clarifications Memo contains further
guidance on how states can reasonably consider modeled visibility
impacts or benefits in the context of a four-factor analysis. 2021
Clarifications Memo at 12-13, 14-15. Specifically, EPA explained that
while visibility can reasonably be used when comparing and choosing
between multiple reasonable control options, it should not be used to
summarily reject controls that are reasonable given the four statutory
factors. 2021 Clarifications Memo at 13. Ultimately, while states have
discretion to reasonably weigh the factors and to determine what level
of control is needed, Sec. 51.308(f)(2)(i) provides that a state
``must include in its implementation plan a description of . . . how
the four factors were taken into consideration in selecting the measure
for inclusion in its long-term strategy.''
---------------------------------------------------------------------------
\23\ See, e.g., Responses to Comments on Protection of
Visibility: Amendments to Requirements for State Plans; Proposed
Rule (81 FR 26942, May 4, 2016), Docket Number EPA-HQ-OAR-2015-0531,
U.S. Environmental Protection Agency at 186; 2019 Guidance at 36-37.
---------------------------------------------------------------------------
As explained above, Sec. 51.308(f)(2)(i) requires states to
determine the emission reduction measures for sources that are
necessary to make reasonable progress by considering the four factors.
Pursuant to Sec. 51.308(f)(2), measures that are necessary to make
reasonable progress towards the national visibility goal must be
included in a state's long-term strategy and in its SIP.\24\ If the
outcome of a four-factor analysis is a new, additional emission
reduction measure for a source, that new measure is necessary to make
reasonable progress towards remedying existing anthropogenic visibility
impairment and must be included in the SIP. If the outcome of a four-
factor analysis is that no new measures are reasonable for a source,
continued implementation of the source's existing measures is generally
necessary to prevent future emission increases and thus to make
reasonable progress towards the second part of the national visibility
goal: preventing future anthropogenic visibility impairment. See CAA
169A(a)(1). That is, when the result of a four-factor analysis is that
no new measures are necessary to make reasonable progress, the source's
existing measures are generally necessary to make reasonable progress
and must be included in the SIP. However, there may be circumstances in
which a state can demonstrate that a source's existing measures are not
necessary to make reasonable progress. Specifically, if a state can
demonstrate that a source will continue to implement its existing
measures and will not increase its emission rate, it may not be
necessary to have those measures in the long-term strategy in order to
prevent future emission increases and future visibility impairment.
EPA's 2021 Clarifications Memo provides further explanation and
guidance on how states may demonstrate that a source's existing
measures are not necessary to make reasonable progress. See 2021
Clarifications Memo at 8-10. If the state can make such a
demonstration, it need not include a source's existing measures in the
long-term strategy or its SIP.
---------------------------------------------------------------------------
\24\ States may choose to, but are not required to, include
measures in their long-term strategies beyond just the emission
reduction measures that are necessary for reasonable progress. See
2021 Clarifications Memo at 16. For example, states with smoke
management programs may choose to submit their smoke management
plans to EPA for inclusion in their SIPs but are not required to do
so. See, e.g., 82 FR at 3108-09 (requirement to consider smoke
management practices and smoke management programs under 40 CFR
51.308(f)(2)(iv) does not require states to adopt such practices or
programs into their SIPs, although they may elect to do so).
---------------------------------------------------------------------------
As with source selection, the characterization of information on
each of the factors is also subject to the documentation requirement in
Sec. 51.308(f)(2)(iii). The reasonable progress analysis, including
source selection, information gathering, characterization of the four
statutory factors (and potentially visibility), balancing of the four
factors, and selection of the emission reduction measures that
represent reasonable progress, is a technically complex exercise, but
also a flexible one that provides states with bounded discretion to
design and implement approaches appropriate to their circumstances.
Given this flexibility, Sec. 51.308(f)(2)(iii) plays an important
function in requiring a state to document the technical basis for its
decision making so that the public and the EPA can comprehend and
evaluate the information and analysis the state relied upon to
determine what emission reduction measures must be in place to make
reasonable progress. The technical documentation must include the
modeling, monitoring, cost, engineering, and emissions information on
which the state relied to determine the measures necessary to make
reasonable progress. This documentation requirement can be met through
the provision of and reliance on technical analyses developed through a
regional planning process, so long as that process and its output has
been approved by all state participants. In addition to the explicit
regulatory requirement to document the technical basis of their
reasonable progress determinations, states are also subject to the
general principle that those determinations must be reasonably moored
to the statute.\25\ That is, a state's decisions about the emission
reduction measures that are necessary to make reasonable progress must
be consistent with the statutory goal of remedying existing and
preventing future visibility impairment.
---------------------------------------------------------------------------
\25\ See Arizona ex rel. Darwin v. U.S. EPA, 815 F.3d 519, 531
(9th Cir. 2016); Nebraska v. U.S. EPA, 812 F.3d 662, 668 (8th Cir.
2016); North Dakota v. EPA, 730 F.3d 750, 761 (8th Cir. 2013);

461, 485, 490 (2004).
---------------------------------------------------------------------------
The four statutory factors (and potentially visibility) are used to
determine what emission reduction measures for selected sources must be
included in a state's long-term strategy for making reasonable
progress. Additionally, the RHR at 40 CFR 51.3108(f)(2)(iv) separately
provides five ``additional factors'' \26\ that states must consider in
developing their long-term strategies: (1) Emission reductions due to
ongoing air pollution control programs, including measures to address
reasonably attributable visibility impairment; (2) measures to reduce
the impacts of construction activities; (3) source retirement and
replacement schedules; (4) basic smoke management practices for
prescribed fire used for agricultural and wildland vegetation
management purposes and smoke management programs; and (5) the
anticipated net effect on visibility due to projected changes in point,
area, and mobile source emissions over the period addressed by the
long-term strategy. The 2019 Guidance provides that a state may satisfy
this requirement by considering these additional factors in the process
of selecting sources for four-factor analysis, when performing that
analysis, or both, and that not every one of the additional factors
needs to be considered at the same stage of the process. See 2019
Guidance at 21. EPA
[[Page 51023]]
provided further guidance on the five additional factors in the 2021
Clarifications Memo, explaining that a state should generally not
reject cost-effective and otherwise reasonable controls merely because
there have been emission reductions since the first planning period
owing to other ongoing air pollution control programs or merely because
visibility is otherwise projected to improve at Class I areas.
Additionally, states should not rely on these additional factors to
summarily assert that the state has already made sufficient progress
and, therefore, no sources need to be selected or no new controls are
needed regardless of the outcome of four-factor analyses. States can,
however, consider these factors in a more tailored manner, e.g., in
choosing between multiple control options when all are reasonable based
on the four statutory factors.\27\ 2021 Clarifications Memo at 13.
---------------------------------------------------------------------------
\26\ The five ``additional factors'' for consideration in
section 51.308(f)(2)(iv) are distinct from the four factors listed
in CAA section 169A(g)(1) and 40 CFR 51.308(f)(2)(i) that states
must consider and apply to sources in determining reasonable
progress.
\27\ In particular, EPA explained in the 2021 Clarifications
Memo that states should not rely on the considerations in 40 CFR
51.308(f)(2)(iv)(A) and (E) to summarily assert that the state has
already made sufficient progress and therefore does not need to
achieve any additional emission reductions. 2021 Clarifications Memo
at 13.
---------------------------------------------------------------------------
Because the air pollution that causes regional haze crosses state
boundaries, Sec. 51.308(f)(2)(ii) requires a state to consult with
other states that also have emissions that are reasonably anticipated
to contribute to visibility impairment in a given Class I area.
Consultation allows for each state that impacts visibility in an area
to share whatever technical information, analyses, and control
determinations may be necessary to develop coordinated emission
management strategies. This coordination may be managed through inter-
and intra-RPO consultation and the development of regional emissions
strategies; additional consultations between states outside of RPO
processes may also occur. If a state, pursuant to consultation, agrees
that certain measures (e.g., a certain emission limitation) are
necessary to make reasonable progress at a Class I area, it must
include those measures in its SIP. 40 CFR 51.308(f)(2)(ii)(A).
Additionally, the RHR requires that states that contribute to
visibility impairment at the same Class I area consider the emission
reduction measures the other contributing states have identified as
being necessary to make reasonable progress for their own sources. 40
CFR 51.308(f)(2)(ii)(B). If a state has been asked to consider or adopt
certain emission reduction measures, but ultimately determines those
measures are not necessary to make reasonable progress, that state must
document in its SIP the actions taken to resolve the disagreement. 40
CFR 51.308(f)(2)(ii)(C). The EPA will consider the technical
information and explanations presented by the submitting state and the
state with which it disagrees when considering whether to approve the
state's SIP. See id.; 2019 Guidance at 53. Under all circumstances, a
state must document in its SIP submission all substantive consultations
with other contributing states. 40 CFR 51.308(f)(2)(ii)(C).
D. Reasonable Progress Goals
Reasonable progress goals ``measure the progress that is projected
to be achieved by the control measures states have determined are
necessary to make reasonable progress based on a four-factor
analysis.'' 82 FR at 3091. Their primary purpose is to assist the
public and the EPA in assessing the reasonableness of states' long-term
strategies for making reasonable progress towards the national
visibility goal. See 40 CFR 51.308(f)(3)(iii)-(iv). States in which
Class I areas are located must establish two RPGs, both in deciviews--
one representing visibility conditions on the clearest days and one
representing visibility on the most anthropogenically impaired days--
for each area within their borders. 40 CFR 51.308(f)(3)(i). The two
RPGs are intended to reflect the projected impacts, on the two sets of
days, of the emission reduction measures the state with the Class I
area, as well as all other contributing states, have included in their
long-term strategies for the second implementation period.\28\ The RPGs
also account for the projected impacts of implementing other CAA
requirements, including non-SIP based requirements. Because RPGs are
the modeled result of the measures in states' long-term strategies (as
well as other measures required under the CAA), they cannot be
determined before states have conducted their four-factor analyses and
determined the control measures that are necessary to make reasonable
progress. See 2021 Clarifications Memo at 6.
---------------------------------------------------------------------------
\28\ RPGs are intended to reflect the projected impacts of the
measures all contributing states include in their long-term
strategies. However, due to the timing of analyses and of control
determinations by other states, other on-going emissions changes, a
particular state's RPGs may not reflect all control measures and
emissions reductions that are expected to occur by the end of the
implementation period. The 2019 Guidance provides recommendations
for addressing the timing of RPG calculations when states are
developing their long-term strategies on disparate schedules, as
well as for adjusting RPGs using a post-modeling approach. 2019
Guidance at 47-48.
---------------------------------------------------------------------------
For the second implementation period, the RPGs are set for 2028.
Reasonable progress goals are not enforceable targets, 40 CFR
51.308(f)(3)(iii); rather, they ``provide a way for the states to check
the projected outcome of the [long-term strategy] against the goals for
visibility improvement.'' 2019 Guidance at 46. While states are not
legally obligated to achieve the visibility conditions described in
their RPGs, Sec. 51.308(f)(3)(i) requires that ``[t]he long-term
strategy and the reasonable progress goals must provide for an
improvement in visibility for the most impaired days since the baseline
period and ensure no degradation in visibility for the clearest days
since the baseline period.'' Thus, states are required to have emission
reduction measures in their long-term strategies that are projected to
achieve visibility conditions on the most impaired days that are better
than the baseline period and shows no degradation on the clearest days
compared to the clearest days from the baseline period. The baseline
period for the purpose of this comparison is the baseline visibility
condition--the annual average visibility condition for the period 2000-
2004. See 40 CFR 51.308(f)(1)(i), 82 FR at 3097-98.
So that RPGs may also serve as a metric for assessing the amount of
progress a state is making towards the national visibility goal, the
RHR requires states with Class I areas to compare the 2028 RPG for the
most impaired days to the corresponding point on the URP line
(representing visibility conditions in 2028 if visibility were to
improve at a linear rate from conditions in the baseline period of
2000-2004 to natural visibility conditions in 2064). If the most
impaired days RPG in 2028 is above the URP (i.e., if visibility
conditions are improving more slowly than the rate described by the
URP), each state that contributes to visibility impairment in the Class
I area must demonstrate, based on the four-factor analysis required
under 40 CFR 51.308(f)(2)(i), that no additional emission reduction
measures would be reasonable to include in its long-term strategy. 40
CFR 51.308(f)(3)(ii). To this end, 40 CFR 51.308(f)(3)(ii) requires
that each state contributing to visibility impairment in a Class I area
that is projected to improve more slowly than the URP provide ``a
robust demonstration, including documenting the criteria used to
determine which sources or groups [of] sources were evaluated and how
the four factors required by paragraph (f)(2)(i) were taken into
consideration in selecting the measures for inclusion in its long-term
strategy.'' The 2019
[[Page 51024]]
Guidance provides suggestions about how such a ``robust demonstration''
might be conducted. See 2019 Guidance at 50-51.
The 2017 RHR, 2019 Guidance, and 2021 Clarifications Memo also
explain that projecting an RPG that is on or below the URP based on
only on-the-books and/or on-the-way control measures (i.e., control
measures already required or anticipated before the four-factor
analysis is conducted) is not a ``safe harbor'' from the CAA's and
RHR's requirement that all states must conduct a four-factor analysis
to determine what emission reduction measures constitute reasonable
progress. The URP is a planning metric used to gauge the amount of
progress made thus far and the amount left before reaching natural
visibility conditions. However, the URP is not based on consideration
of the four statutory factors and therefore cannot answer the question
of whether the amount of progress being made in any particular
implementation period is ``reasonable progress.'' See 82 FR at 3093,
3099-3100; 2019 Guidance at 22; 2021 Clarifications Memo at 15-16.
E. Monitoring Strategy and Other State Implementation Plan Requirements
Section 51.308(f)(6) requires states to have certain strategies and
elements in place for assessing and reporting on visibility. Individual
requirements under this subsection apply either to states with Class I
areas within their borders, states with no Class I areas but that are
reasonably anticipated to cause or contribute to visibility impairment
in any Class I area, or both. A state with Class I areas within its
borders must submit with its SIP revision a monitoring strategy for
measuring, characterizing, and reporting regional haze visibility
impairment that is representative of all Class I areas within the
state. SIP revisions for such states must also provide for the
establishment of any additional monitoring sites or equipment needed to
assess visibility conditions in Class I areas, as well as reporting of
all visibility monitoring data to the EPA at least annually. Compliance
with the monitoring strategy requirement may be met through a state's
participation in the Interagency Monitoring of Protected Visual
Environments (IMPROVE) monitoring network, which is used to measure
visibility impairment caused by air pollution at the 156 Class I areas
covered by the visibility program. 40 CFR 51.308(f)(6), (f)(6)(i),
(f)(6)(iv). The IMPROVE monitoring data is used to determine the 20%
most anthropogenically impaired and 20% clearest sets of days every
year at each Class I area and tracks visibility impairment over time.
All states' SIPs must provide for procedures by which monitoring
data and other information are used to determine the contribution of
emissions from within the state to regional haze visibility impairment
in affected Class I areas. 40 CFR 51.308(f)(6)(ii), (iii). Section
51.308(f)(6)(v) further requires that all states' SIPs provide for a
statewide inventory of emissions of pollutants that are reasonably
anticipated to cause or contribute to visibility impairment in any
Class I area; the inventory must include emissions for the most recent
year for which data are available and estimates of future projected
emissions. States must also include commitments to update their
inventories periodically. The inventories themselves do not need to be
included as elements in the SIP and are not subject to EPA review as
part of the Agency's evaluation of a SIP revision.\29\ All states' SIPs
must also provide for any other elements, including reporting,
recordkeeping, and other measures, that are necessary for states to
assess and report on visibility. 40 CFR 51.308(f)(6)(vi). Per the 2019
Guidance, a state may note in its regional haze SIP that its compliance
with the Air Emissions Reporting Rule (AERR) in 40 CFR part 51 Subpart
A satisfies the requirement to provide for an emissions inventory for
the most recent year for which data are available. To satisfy the
requirement to provide estimates of future projected emissions, a state
may explain in its SIP how projected emissions were developed for use
in establishing RPGs for its own and nearby Class I areas.\30\
---------------------------------------------------------------------------
\29\ See ``Step 8: Additional requirements for regional haze
SIPs'' in 2019 Regional Haze Guidance at 55.
\30\ Id.
---------------------------------------------------------------------------
Separate from the requirements related to monitoring for regional
haze purposes under 40 CFR 51.308(f)(6), the RHR also contains a
requirement at Sec. 51.308(f)(4) related to any additional monitoring
that may be needed to address visibility impairment in Class I areas
from a single source or a small group of sources. This is called
``reasonably attributable visibility impairment.'' \31\ Under this
provision, if the EPA or the FLM of an affected Class I area has
advised a state that additional monitoring is needed to assess
reasonably attributable visibility impairment, the state must include
in its SIP revision for the second implementation period an appropriate
strategy for evaluating such impairment.
---------------------------------------------------------------------------
\31\ EPA's visibility protection regulations define ``reasonably
attributable visibility impairment'' as ``visibility impairment that
is caused by the emission of air pollutants from one, or a small
number of sources.'' 40 CFR 51.301.
---------------------------------------------------------------------------
F. Requirements for Periodic Reports Describing Progress Towards the
Reasonable Progress Goals
Section 51.308(f)(5) requires a state's regional haze SIP revision
to address the requirements of paragraphs 40 CFR 51.308(g)(1) through
(5) so that the plan revision due in 2021 will serve also as a progress
report addressing the period since submission of the progress report
for the first implementation period. The regional haze progress report
requirement is designed to inform the public and the EPA about a
state's implementation of its existing long-term strategy and whether
such implementation is in fact resulting in the expected visibility
improvement. See 81 FR 26942, 26950 (May 4, 2016), (82 FR at 3119,
January 10, 2017). To this end, every state's SIP revision for the
second implementation period is required to describe the status of
implementation of all measures included in the state's long-term
strategy, including BART and reasonable progress emission reduction
measures from the first implementation period, and the resulting
emissions reductions. 40 CFR 51.308(g)(1) and (2).
A core component of the progress report requirements is an
assessment of changes in visibility conditions on the clearest and most
impaired days. For second implementation period progress reports, Sec.
51.308(g)(3) requires states with Class I areas within their borders to
first determine current visibility conditions for each area on the most
impaired and clearest days, 40 CFR 51.308(g)(3)(i)(B), and then to
calculate the difference between those current conditions and baseline
(2000-2004) visibility conditions in order to assess progress made to
date. See 40 CFR 51.308(g)(3)(ii)(B). States must also assess the
changes in visibility impairment for the most impaired and clearest
days since they submitted their first implementation period progress
reports. See 40 CFR 51.308(g)(3)(iii)(B), (f)(5). Since different
states submitted their first implementation period progress reports at
different times, the starting point for this assessment will vary state
by state.
Similarly, states must provide analyses tracking the change in
emissions of pollutants contributing to visibility impairment from all
sources and activities within the state over the period since they
submitted their first implementation period progress reports. See 40
CFR 51.308(g)(4), (f)(5). Changes in emissions should be identified by
the
[[Page 51025]]
type of source or activity. Section 51.308(g)(5) also addresses changes
in emissions since the period addressed by the previous progress report
and requires states' SIP revisions to include an assessment of any
significant changes in anthropogenic emissions within or outside the
state. This assessment must include an explanation of whether these
changes in emissions were anticipated and whether they have limited or
impeded progress in reducing emissions and improving visibility
relative to what the state projected based on its long-term strategy
for the first implementation period.
G. Requirements for State and Federal Land Manager Coordination
Clean Air Act section 169A(d) requires that before a state holds a
public hearing on a proposed regional haze SIP revision, it must
consult with the appropriate FLM or FLMs; pursuant to that
consultation, the state must include a summary of the FLMs' conclusions
and recommendations in the notice to the public. Consistent with this
statutory requirement, the RHR also requires that states ``provide the
[FLM] with an opportunity for consultation, in person and at a point
early enough in the State's policy analyses of its long-term strategy
emission reduction obligation so that information and recommendations
provided by the [FLM] can meaningfully inform the State's decisions on
the long-term strategy.'' 40 CFR 51.308(i)(2). Consultation that occurs
120 days prior to any public hearing or public comment opportunity will
be deemed ``early enough,'' but the RHR provides that in any event the
opportunity for consultation must be provided at least 60 days before a
public hearing or comment opportunity. This consultation must include
the opportunity for the FLMs to discuss their assessment of visibility
impairment in any Class I area and their recommendations on the
development and implementation of strategies to address such
impairment. 40 CFR 51.308(i)(2). In order for the EPA to evaluate
whether FLM consultation meeting the requirements of the RHR has
occurred, the SIP submission should include documentation of the timing
and content of such consultation. The SIP revision submitted to the EPA
must also describe how the state addressed any comments provided by the
FLMs. 40 CFR 51.308(i)(3). Finally, a SIP revision must provide
procedures for continuing consultation between the state and FLMs
regarding the state's visibility protection program, including
development and review of SIP revisions, five-year progress reports,
and the implementation of other programs having the potential to
contribute to impairment of visibility in Class I areas. 40 CFR
51.308(i)(4).
IV. The EPA's Evaluation of New Jersey's Regional Haze Submission for
the Second Implementation Period
A. Background on New Jersey's First Implementation Period SIP
Submission
NJDEP submitted its regional haze SIP for the first implementation
period to the EPA on July 28, 2009, and supplemented it on December 9,
2010, March 2, 2011, and December 7, 2011. The EPA approved New
Jersey's first implementation period regional haze SIP submission on
January 3, 2012 (77 FR 19, January 3, 2012). EPA's approval included,
but was not limited to, the portions of the plan that address the
reasonable progress requirements, New Jersey's implementation of Best
Available Retrofit Technologies on eligible sources, and New Jersey's
Subchapter 9,\32\ Sulfur in Fuels rule. The requirements for regional
haze SIPs for the first implementation period are contained in 40 CFR
51.308(d) and (e). 40 CFR 51.308(b). Pursuant to 40 CFR 51.308(g), New
Jersey was also responsible for submitting a five-year progress report
as a SIP revision for the first implementation period, which it did on
June 28, 2016. The EPA approved the progress report into the New Jersey
SIP on September 29, 2017 (82 FR 45472, September 29, 2017).
---------------------------------------------------------------------------
\32\ See N.J.A.C. 7:27-9 ``Sulfur in Fuels''.
---------------------------------------------------------------------------
B. New Jersey's Second Implementation Period SIP Submission and the
EPA's Evaluation
In accordance with CAA sections 169A and the RHR at 40 CFR
51.308(f), on March 26, 2020,\33\ NJDEP submitted a revision to the New
Jersey SIP to address its regional haze obligations for the second
implementation period, which runs through 2028. New Jersey made its
2020 Regional Haze SIP submission available for public comment on
August 22, 2019. NJDEP received and responded to public comments and
included the comments and responses to those comments in their
submission.
---------------------------------------------------------------------------
\33\ NJDEP supplemented its SIP submission on September 8, 2020,
and April 1, 2021.
---------------------------------------------------------------------------
The following sections describe New Jersey's SIP submission,
including analyses conducted by MANE-VU and New Jersey's determinations
based on those analyses, New Jersey's assessment of progress made since
the first implementation period in reducing emissions of visibility
impairing pollutants, and the visibility improvement progress at its
Class I area and nearby Class I areas. This notice also contains EPA's
evaluation of New Jersey's submission against the requirements of the
CAA and RHR for the second implementation period of the regional haze
program.
C. Identification of Class I Areas
Section 169A(b)(2) of the CAA requires each state in which any
Class I area is located or ``the emissions from which may reasonably be
anticipated to cause or contribute to any impairment of visibility'' in
a Class I area to have a plan for making reasonable progress toward the
national visibility goal. The RHR implements this statutory requirement
at 40 CFR 51.308(f), which provides that each state's plan ``must
address regional haze in each mandatory Class I Federal area located
within the State and in each mandatory Class I Federal area located
outside the State that may be affected by emissions from within the
State,'' and (f)(2), which requires each state's plan to include a
long-term strategy that addresses regional haze in such Class I areas.
The EPA explained in the 1999 RHR preamble that the CAA section
169A(b)(2) requirement that states submit SIPs to address visibility
impairment establishes ``an `extremely low triggering threshold' in
determining which States should submit SIPs for regional haze.'' 64 FR
at 35721. In concluding that each of the contiguous 48 states and the
District of Columbia meet this threshold,\34\ the EPA relied on ``a
large body of evidence demonstrat[ing] that long-range transport of
fine PM contributes to regional haze,'' id., including modeling studies
that ``preliminarily demonstrated that each State not having a Class I
area had emissions contributing to impairment in at least one downwind
Class I area.'' Id. at 35722. In addition to the technical evidence
supporting a conclusion that each state contributes to existing
visibility impairment, the EPA also explained that the second half of
the national visibility goal--preventing future visibility impairment--
requires having a framework in place to address future growth in
visibility-impairing emissions and makes it inappropriate to
``establish criteria for excluding States
[[Page 51026]]
or geographic areas from consideration as potential contributors to
regional haze visibility impairment.'' Id. at 35721. Thus, the EPA
concluded that the agency's ``statutory authority and the scientific
evidence are sufficient to require all States to develop regional haze
SIPs to ensure the prevention of any future impairment of visibility,
and to conduct further analyses to determine whether additional control
measures are needed to ensure reasonable progress in remedying existing
impairment in downwind Class I areas.'' Id. at 35722. EPA's 2017
revisions to the RHR did not disturb this conclusion. See 82 FR at
3094.
---------------------------------------------------------------------------
\34\ EPA determined that ``there is more than sufficient
evidence to support our conclusion that emissions from each of the
48 contiguous states and the District of Columba may reasonably be
anticipated to cause or contribute to visibility impairment in a
Class I area.'' 64 FR at 35721. Hawaii, Alaska, and the U.S. Virgin
Islands must also submit regional haze SIPs because they contain
Class I areas.
---------------------------------------------------------------------------
New Jersey has one mandatory Class I Federal area within its
borders, the Brigantine Wilderness Area of the Edwin B. Forsythe
National Wildlife Refuge. For the second implementation period, MANE-VU
performed technical analyses \35\ to help assess source and state-level
contributions to visibility impairment and the need for interstate
consultation. MANE-VU used the results of these analyses to determine
which states' emissions ``have a high likelihood of affecting
visibility in MANE-VU's Class I areas.'' \36\ Similar to metrics used
in the first implementation period,\37\ MANE-VU used a greater than 2
percent of sulfate plus nitrate emissions contribution criteria to
determine whether emissions from individual jurisdictions within the
region affected visibility in any Class I areas. The MANE-VU analyses
for the second implementation period used a combination of data
analysis techniques, including emissions data, distance from Class I
areas, wind trajectories, and CALPUFF dispersion modeling. Although
many of the analyses focused only on SO2 emissions and
resultant particulate sulfate contributions to visibility impairment,
some also incorporated NOX emissions to estimate particulate
nitrate contributions.
---------------------------------------------------------------------------
\35\ The contribution assessment methodologies for MANE-VU Class
I areas are summarized in appendix E1 of the docket. ``Selection of
States for MANE-VU Regional Haze Consultation (2018).''
\36\ Id.
\37\ See docket EPA-R02-OAR-2011-0607 for MANE-VU supporting
materials.
---------------------------------------------------------------------------
One MANE-VU analysis used for contribution assessment was CALPUFF
air dispersion modeling. The CALPUFF model was used to estimate sulfate
and nitrate formation and transport in MANE-VU and nearby regions
originating from large electric generating unit (EGU) point sources and
other large industrial and institutional sources in the eastern and
central United States. Information from an initial round of CALPUFF
modeling was collated for the 444 EGUs that were determined to warrant
further scrutiny based on their emissions of SO2 and
NOX. The list of EGUs was based on an enhanced ``Q/d''
analysis \38\ that considered recent SO2 emissions in the
eastern United States and an analysis that adjusted previous 2002 MANE-
VU CALPUFF modeling by applying a ratio of 2011 to 2002 SO2
emissions. This list of sources was then enhanced by including the top
five SO2 and NOX emission sources for 2011 for
each state included in the modeling domain. A total of 311 EGU stacks
(as opposed to individual units) were included in the CALPUFF modeling
analysis. Initial information was also collected on the 50 industrial
and institutional sources that, according to 2011 Q/d analysis,
contributed the most to visibility impact in each Class I area. The
ultimate CALPUFF modeling run included a total of 311 EGU stacks and 82
industrial facilities. The summary report for the CALPUFF modeling
included the top 10 most impacting EGUs and the top 5 most impacting
industrial/institutional sources for each Class I area and compiled
those results into a ranked list of the most impacting EGUs and
industrial sources at MANE-VU Class I areas.\39\
---------------------------------------------------------------------------
\38\ ``Q/d'' is emissions (Q) in tons per year, typically of one
or a combination of visibility-impairing pollutants, divided by
distance to a class I area (d) in kilometers. The resulting ratio is
commonly used as a metric to assess a source's potential visibility
impacts on a particular class I area.
\39\ See appendix F1 in the docket, ``MANE-VU CALPUFF Modeling
Report--Final.''
---------------------------------------------------------------------------
New Jersey had an EGU and two industrial/institutional sources that
were included in the MANE-VU CALPUFF modeling.\40\ The modeling
identified the EGU facility BL England (units 1, 2 & 3) as impacting
the Brigantine Wilderness, Dolly Sods and Shenandoah Class I areas.
Unit 1 ranked 4th on MANE-VU's list and units 2 & 3 ranked 10th for
impacts at the Brigantine Wilderness Class I area. Although BL England
impacted the Dolly Sods and Shenandoah Class I areas, it did not rank
amongst the top 10 impacting EGUs. The two industrial/institutional
sources identified by the modeling were Atlantic County Utilities
Authority (ACUA), which ranked 5th for impacts at the Brigantine
Wilderness Class I area, and Gerresheimer Moulded Glass, which was not
ranked among the top 5 visibility impairing industrial/institutional
sources at any Class I areas. In its submittal, New Jersey indicates
that BL England ceased operations and shut down in May of 2019. NJDEP's
Southern Air Compliance and Enforcement office conducted a site
investigation at BL England September 20, 2019, and observed that units
1, 2, and 3 are decommissioned and rendered inoperable. On December 3,
2019, the NJDEP terminated the air operating permit at BL England
Generating Station.\41\ Additionally, at the time of the analysis, the
industrial, commercial and institutional (ICI) boilers at ACUA and
Gerresheimer Moulded Glass (now Corning Pharmaceutical Glass)
contributed 1.67 inverse megameters (Mm-1) and 1.0 Mm-1, respectively,
based on their close proximity to Brigantine. However, this assessment
was based on the sources' 2011 configurations and emission rates.
Currently, there are no permitted ICI boilers at these facilities. In
2019, ACUA's emissions were 19 tons per year (tpy) for NOX
and 19 tpy for SO2, while the 2011 emissions of
SO2 were 907.88 tpy. The 2019 annual emissions at Corning
Pharmaceuticals were 54 tpy for NOX and 1 tpy for
SO2, while the 2011 emissions of SO2 were
3,007.04 tpy.\42\
---------------------------------------------------------------------------
\40\ See tables 4, 5, 6, 34 and 35 in appendix F1 in the docket.
\41\ See appendix J9, ``BL England Operating Permit Termination
Letter--Final.''
\42\ See Table 3-2 ``82 Industrial Sources Evaluated for Impact
at MANE-VU Class I Areas'' in the NJ Regional Haze SIP--Final March
2020.
---------------------------------------------------------------------------
The second MANE-VU contribution analysis used a meteorologically
weighted Q/d calculation to assess states' contributions to visibility
impairment at MANE-VU Class I areas.\43\ This analysis focused
predominantly on SO2 emissions and used cumulative
SO2 emissions from a source and a state for the variable
``Q,'' and the distance of the source or state to the IMPROVE monitor
receptor at a Class I area as ``d.'' The result is then multiplied by a
constant (Ci), which is determined based on the prevailing
wind patterns. MANE-VU selected a meteorologically weighted Q/d
analysis as an inexpensive initial screening tool that could easily be
repeated to determine which states, sectors, or sources have a larger
relative impacts and warrant further analysis. MANE-VU's analysis
estimated New Jersey's maximum sulfate contribution was 1.32% at the
Brigantine Wilderness Class I area based on the maximum daily impact;
New Jersey's SO2 emission contribution did not exceed 1% for
any other Class I area. Although MANE-VU did not originally estimate
nitrate impacts, the MANE-VU Q/d analysis was subsequently extended to
account for nitrate contributions from NOX emissions and to
approximate the
[[Page 51027]]
nitrate impacts from area and mobile sources. MANE-VU therefore
developed a ratio of nitrate to sulfate impacts based on the previously
described CALPUFF modeling and applied those to the sulfate Q/d results
in order to derive nitrate contribution estimates. Several states did
not have CALPUFF nitrate to sulfate ratio results, however, because
there were no point sources modeled with CALPUFF.
---------------------------------------------------------------------------
\43\ See appendix G1, ``Contribution Assessment 2006--Final.''
---------------------------------------------------------------------------
In order to develop a final set of contribution estimates, MANE-VU
weighted the results from both the Q/d and CALPUFF analyses. The MANE-
VU mass-weighted sulfate and nitrate contribution results were reported
for the MANE-VU Class I areas (the Q/d summary report included results
for several non-MANE-VU areas as well). If a state's contribution to
sulfate and nitrate concentrations at a particular Class I area was 2
percent or greater, MANE-VU regarded that state as contributing to
visibility impairment in that area. According to MANE-VU's analyses,
sources in New Jersey have been found to contribute to visibility
impairment at its own Class I area, the Brigantine Wilderness, and at
the Dolly Sods Wilderness in West Virginia and Shenandoah National Park
in Virginia. However, because New Jersey's mass-weighted contribution
to sulfate and nitrate concentrations exceeded the 2 percent threshold
only at Brigantine Wilderness (New Jersey's contribution was 2.2%), the
RPO and New Jersey determined that it did not contribute to visibility
impairment at Dolly Sods, Shenandoah, or any other Class I area.
As explained above, the EPA concluded in the 1999 RHR that ``all
[s]tates contain sources whose emissions are reasonably anticipated to
contribute to regional haze in a Class I area,'' 64 FR at 35721, and
this determination was not changed in the 2017 RHR. Critically, the
statute and regulation both require that the cause-or-contribute
assessment consider all emissions of visibility-impairing pollutants
from a state, as opposed to emissions of a particular pollutant or
emissions from a certain set of sources. Consistent with these
requirements, the 2019 Guidance makes it clear that ``all types of
anthropogenic sources are to be included in the determination'' of
whether a state's emissions are reasonably anticipated to result in any
visibility impairment. 2019 Guidance at 8.
First, as an aside, the screening analyses on which MANE-VU relied
are useful for certain purposes. MANE-VU used information from its
technical analysis to rank the largest contributing states to sulfate
and nitrate impairment in five Class I areas within MANE-VU states and
three additional, nearby Class I areas.\44\ The rankings were used to
determine upwind states that were deemed important to include in state-
to-state consultation (based on an identified impact screening
threshold). Additionally, large individual source impacts were used to
target MANE-VU control analysis ``Asks'' \45\ of states and sources
both within and upwind of MANE-VU.\46\ The EPA finds the nature of the
analyses generally appropriate to support decisions on states with
which to consult. However, we have cautioned that source selection
methodologies that target the largest regional contributors to
visibility impairment across multiple states may not be reasonable for
a particular state if it results in few or no sources being selected
for subsequent analysis. 2021 Clarifications Memo at 3.
---------------------------------------------------------------------------
\44\ The Class I areas analyzed were Acadia National Park in
Maine, Brigantine Wilderness in New Jersey, Great Gulf Wilderness in
New Hampshire, Lye Brook Wilderness in Vermont, Moosehorn Wilderness
in Maine, Shenandoah National Park in Virginia, James River Face
Wilderness in Virginia, and Dolly Sods/Otter Creek Wildernesses in
West Virginia.
\45\ As explained more fully in Section IV.E.a, MANE-VU refers
to each of the components of its overall strategy as an ``Ask ``of
its member states.
\46\ The MANE-VU consultation report (Appendix D) explains that
``[t]he objective of this technical work was to identify states and
sources from which MANE-VU will pursue further analysis. This
screening was intended to identify which states to invite to
consultation, not a definitive list of which states are
contributing.''
---------------------------------------------------------------------------
With regard to the analysis and determinations regarding New
Jersey's contribution to visibility impairment at out-of-state Class I
areas, the MANE-VU technical work focuses on the magnitude of
visibility impacts from certain New Jersey emissions on its Class I
area and other nearby Class I areas. However, the analyses did not
account for all emissions and all components of visibility impairment
(e.g., primary PM emissions, and impairment from fine PM, elemental
carbon, and organic carbon). In addition, Q/d analyses with a
relatively simplistic accounting for wind trajectories and CALPUFF
applied to a very limited set of EGUs and major industrial sources of
SO2 and NOX are not scientifically rigorous tools
capable of evaluating contribution to visibility impairment from all
emissions in a state. The EPA does agree that the contribution to
visibility impairment from New Jersey's emissions at nearby out-of-
state Class I areas is smaller than that from numerous other MANE-VU
states.\47\ And while New Jersey noted that the contributions from
several states outside the MANE-VU region are significantly larger than
its own, we again clarify that each state is obligated under the CAA
and RHR to address regional haze visibility impairment resulting from
emissions from within the state, irrespective of whether another
state's contribution is greater. See 2021 Clarifications Memo at 3.
Additionally, we note that the 2 percent or greater sulfate-plus-
nitrate threshold used to determine whether New Jersey emissions
contribute to visibility impairment at a particular Class I area may be
higher than what EPA believes is an ``extremely low triggering
threshold'' intended by the statute and regulations. In sum, based on
the information provided, it is clear that emissions from New Jersey
contribute to Brigantine Wilderness and have relatively small
contributions to other out-of-state Class I areas. However, due to the
low triggering threshold implied by the Rule and the lack of rigorous
modeling analyses, we do not necessarily agree with New Jersey's
conclusion that, based on a 2% contribution threshold, it does not
contribute to visibility impairment at any Class I areas outside the
state.
---------------------------------------------------------------------------
\47\ Because MANE-VU did not include all New Jersey's emissions
or contributions to visibility impairment in its analysis, we cannot
definitely state that New Jersey's contribution to visibility
impairment is not the most significant. However, that is very likely
the case.
---------------------------------------------------------------------------
Regardless, we note that New Jersey did determine that sources and
emissions within the state contribute to visibility impairment at both
Brigantine and two out-of-state Class I areas. Furthermore, the state
took part in the emission control strategy consultation process as a
member of MANE-VU. As part of that process, MANE-VU developed a set of
emissions reduction measures identified as being necessary to make
reasonable progress in the five MANE-VU Class I areas. This strategy
consists of six Asks for states within MANE-VU and five Asks for states
outside the region that were found to impact visibility at Class I
areas within MANE-VU.\48\ New Jersey's submission discusses each of the
Asks and explains why or why not each is applicable and how it has
complied with the relevant components of the emissions control strategy
MANE-VU has laid out for its states. New Jersey worked with MANE-VU to
determine potential reasonable measures that could be implemented by
2028, considering the cost of compliance, the time necessary for
compliance, the energy and non-air quality environmental impacts, and
the remaining useful life of any potentially affected sources. As
discussed in further
[[Page 51028]]
detail below, the EPA is proposing to find that New Jersey has
submitted a regional haze plan that meets the requirements of 40 CFR
51.308(f)(2) related to the development of a long-term strategy. Thus,
although we have concerns regarding some aspects of MANE-VU's technical
analyses supporting states' contribution determinations, we propose to
find that New Jersey has nevertheless satisfied the applicable
requirements for making reasonable progress towards natural visibility
conditions in Class I areas that may be affected be emissions from the
state.
---------------------------------------------------------------------------
\48\ See appendix B, ``Asks--Final.''
---------------------------------------------------------------------------
D. Calculations of Baseline, Current, and Natural Visibility
Conditions; Progress to Date; and the Uniform Rate of Progress
Section 51.308(f)(1) requires states to determine the following for
``each mandatory Class I Federal area located within the State'':
baseline visibility conditions for the most impaired and clearest days,
natural visibility conditions for the most impaired and clearest days,
progress to date for the most impaired and clearest days, the
differences between current visibility conditions and natural
visibility conditions, and the URP. This section also provides the
option for states to propose adjustments to the URP line for a Class I
area to account for visibility impacts from anthropogenic sources
outside the United States and/or the impacts from wildland prescribed
fires that were conducted for certain, specified objectives. 40 CFR
51.308(f)(1)(vi)(B).
Brigantine Wilderness Area has 2000-2004 baseline visibility
conditions of 14.33 deciviews on the 20% clearest days and 27.43
deciviews on the 20% most impaired days. New Jersey calculated an
estimated natural background visibility of 5.52 deciviews on the 20%
clearest days and 10.69 deciviews on the 20% most impaired days for the
Brigantine Wilderness Area.\49\ The current visibility conditions,
which are based on 2013-2017 monitoring data, were 11.48 deciviews on
the clearest days and 19.86 deciviews on the most impaired days, which
are 5.96 deciviews and 9.17 deciviews greater than natural conditions
on the respective sets of days.\50\ New Jersey calculated an annual URP
of 0.28 deciviews needed to reach natural visibility on the 20% most
impaired days.\51\ New Jersey's URP in 2028 on 20% most impaired
visibility days is 20.74 deciviews. New Jersey noted that its modeled
``2028 Base Case'' and ``2028 Control Case'' are both below the URP.
New Jersey did not choose to adjust its URP for international
anthropogenic impacts or to account for the impacts of wildland
prescribed fires. EPA is proposing to find that New Jersey has
submitted a regional haze plan that meets the requirements of 40 CFR
51.308(f)(1) related to the calculations of baseline, current, and
natural visibility conditions; progress to date; and the uniform rate
of progress for the second implementation period.

E. Long-Term Strategy for Regional Haze
a. New Jersey's Response to the Six MANE-VU Asks
Each state having a Class I area within its borders or emissions
that may affect visibility in a Class I area must develop a long-term
strategy for making reasonable progress towards the national visibility
goal. CAA 169A(b)(2)(B). As explained in the Background section of this
notice, reasonable progress is achieved when all states contributing to
visibility impairment in a Class I area are implementing the measures
determined--through application of the four statutory factors to
sources of visibility impairing pollutants--to be necessary to make
reasonable progress. 40 CFR 51.308(f)(2)(i). Each state's long-term
strategy must include the enforceable emission limitations, compliance
schedules, and other measures that are necessary to make reasonable
progress. 40 CFR 51.308(f)(2). All new (i.e., additional) measures that
are the outcome of four-factor analyses are necessary to make
reasonable progress and must be in the long-term strategy. If the
outcome of a four-factor analysis is that no new measures are
reasonable for a source, that source's existing measures are necessary
to make reasonable progress, unless the state can demonstrate that the
source will continue to implement those measures and will not increase
its emission rate. Existing measures that are necessary to make
reasonable progress must also be in the long-term strategy. In
developing its long-term strategies, a state must also consider the
five additional factors in Sec. 51.308(f)(2)(iv). As part of its
reasonable progress determinations, the state must describe the
criteria used to determine which sources or group of sources were
evaluated (i.e., subjected to four-factor analysis) for the second
implementation period and how the four factors were taken into
consideration in selecting the emission reduction measures for
inclusion in the long-term strategy. 40 CFR 51.308(f)(2)(iii).
The following section summarizes how New Jersey's SIP submission
addressed the requirements of Sec. 51.308(f)(2)(i); specifically, it
describes MANE-VU's development of the six Asks and how New Jersey
addressed each. The EPA's evaluation of New Jersey's SIP revision with
regard to the same is contained in the following Section IV.E.b. New
Jersey's SIP submission describes how it plans to meet the long-term
strategy requirements defined by the state and MANE-VU and provides
that ``[t]hese long-term strategies are referred to as the `Asks'.''

\52\ NJ Regional Haze SIP submission at 26.
---------------------------------------------------------------------------
States may rely on technical information developed by the RPOs of
which they are members to select sources for four-factor analysis and
to conduct that analysis, as well as to satisfy the documentation
requirements under Sec. 51.308(f). Where an RPO has performed source
selection and/or four-factor analyses (or considered the five
additional factors in Sec. 51.308(f)(2)(iv)) for its member states,
those states may rely on the RPO's analyses for the purpose of
satisfying the requirements of Sec. 51.308(f)(2)(i) so long as the
states have a reasonable basis to do so and all state participants in
the RPO process have approved the technical analyses. 40 CFR
51.308(f)(3)(iii). States may also satisfy the requirement of Sec.
51.308(f)(2)(ii) to engage in interstate consultation with other states
that have emissions that are reasonably anticipated to contribute to
visibility impairment in a given Class I area under the auspices of
intra- and inter-RPO engagement.
New Jersey is a member of the MANE-VU RPO and participated in the
RPO's regional approach to developing a strategy for making reasonable
progress towards the national visibility goal in the MANE-VU Class I
areas. MANE-VU's strategy includes a combination of: (1) Measures for
certain source sectors and groups of sectors that the RPO determined
were reasonable for states to pursue, and (2) a request for member
states to conduct four-factor analyses for individual sources that it
[[Page 51029]]
identified as contributing to visibility impairment. MANE-VU refers to
each of the components of its overall strategy as an Ask of its member
states. On August 25, 2017, the Executive Director of MANE-VU, on
behalf of the MANE-VU states and tribal nations, signed a statement
that identifies six emission reduction measures that comprise the Asks
for the second implementation period.\53\ The Asks were ``designed to
identify reasonable emission reduction strategies that must be
addressed by the states and tribal nations of MANE-VU through their
regional haze SIP updates.'' \54\ The statement explains that ``[i]f
any State cannot agree with or complete a Class I State's Asks, the
State must describe the actions taken to resolve the disagreement in
the Regional Haze SIP.'' \55\

---------------------------------------------------------------------------
MANE-VU's recommendations as to the appropriate control measures
were based on technical analyses documented in the RPO's reports and
included as appendices to or referenced in New Jersey's regional haze
SIP submission. One of the initial steps of MANE-VU's technical
analysis was to determine which visibility-impairing pollutants should
be the focus of its efforts for the second implementation period. In
the first implementation period, MANE-VU determined that sulfates were
the most significant visibility impairing pollutant at the region's
Class I areas. To determine the impact of certain pollutants on
visibility at Class I areas for the purpose of second implementation
period planning, MANE-VU conducted an analysis comparing the pollutant
contribution on the clearest and most impaired days in the baseline
period (2000-2004) to the most recent period (2012-2016) \56\ at MANE-
VU and nearby Class I areas. MANE-VU found that while SO2
emissions were decreasing and visibility was improving, sulfates still
made up the most significant contribution to visibility impairment at
MANE-VU and nearby Class I areas. According to the analysis,
NOX emissions have begun to play a more significant role in
visibility impacts in recent years, especially at the Brigantine
Wilderness Area. The technical analyses used by New Jersey are included
in their submission and are as follows:
---------------------------------------------------------------------------
\56\ The period of 2012-2016 was the most recent period for
which data was available at the time of analysis.

To support development of the Asks, MANE-VU gathered information on
each of the four statutory factors for six source sectors it
determined, based on an examination of annual emission inventories,
``had emissions that were reasonabl[y] anticipated to contribute to
visibility degradation in MANE-VU:'' electric generating units (EGUs),
industrial/commercial/institutional boilers (ICI boilers), cement
kilns, heating oil, residential wood combustion, and outdoor wood
combustion.\57\ MANE-VU also collected data on individual sources
within the EGU, ICI boiler, and cement kiln sectors.\58\ Information
for the six sectors included explanations of technically feasible
control options for SO2 or NOX, illustrative
cost-effectiveness estimates for a range of model units and control
options, sector-wide cost considerations, potential time frames for
compliance with control options, potential energy and non-air-quality
environmental impacts of certain control options, and how the remaining
useful lives of sources might be considered in a control analysis.\59\
Source-specific data included SO2 emissions \60\ and
existing controls \61\ for certain existing EGUs, ICI boilers, and
cement kilns. MANE-VU considered this information on the four factors
as well as the analyses developed by the RPO's Technical Support
Committee when it determined specific emission reduction measures that
were found to be reasonable for certain sources within two of the
sectors it had examined--EGUs and ICI boilers. The Asks were based on
this analysis and looked to either optimize the use of existing
controls, have states conduct further analysis on EGU or ICI boilers
with considerable visibility impacts, implement low sulfur fuel
standards, or lock-in lower emission rates.

MANE-VU Ask 1 is ``ensuring the most effective use of control
technologies on a year-round basis'' at EGUs with a nameplate capacity
larger than or equal to 25 megawatts (MW) with already installed
NOX and/or SO2 controls.\62\ In its submission,
New Jersey explained that the control limits required by its Reasonably
Available Control Technology rules, SIP-approved N.J.A.C 7:27-19,
Control and Prohibition of Air Pollution by Oxides of Nitrogen, include
year-round emission limits. Additionally, New Jersey's operating
permits require that units run their controls on a year-round basis
whenever the units are in operation to ensure the most effective use of
control technologies. New Jersey therefore concluded it is meeting Ask
1.
---------------------------------------------------------------------------
\62\ See appendix D ``MANE-VU Regional Haze Consultation Report
and Consultation Documentation--Final.''
---------------------------------------------------------------------------
MANE-VU Ask 2 consists of a request that states ``perform a four-
factor analysis for reasonable installation or upgrade to emissions
controls'' for specified sources. MANE-VU developed
[[Page 51030]]
its Ask 2 list of sources for analysis by performing modeling and
identifying facilities with the potential for 3.0 inverse megameters
(Mm-1) or greater impacts on visibility at any Class I area
in the MANE-VU region. The BL England facility located in Upper
Township, Cape May County, New Jersey was identified by MANE-VU \63\ as
having units--units 2 and 3--with the potential for 3.0 Mm-1
or greater visibility impact at any MANE-VU Class I area. The BL
England facility permanently shut down in May 2019. The NJDEP Southern
Air Compliance and Enforcement office conducted a site investigation at
BL England on September 20, 2019, and observed that units 1, 2, and 3
are decommissioned and rendered inoperable. On December 3, 2019, the
DEP terminated \64\ the air operating permit at BL England Generating
Station. New Jersey therefore concluded that it satisfies Ask 2.
---------------------------------------------------------------------------
\63\ See Table 4-1 in Chapter 4 of the NJ Regional Haze SIP.
\64\ See Appendix J9 ``BL England Operating Permit Termination
Letter--Final.''
---------------------------------------------------------------------------
Ask 3 is for each MANE-VU state to pursue an ultra low-sulfur fuel
oil standard if it has not already done so in the first implementation
period. The Ask includes percent by weight standards for #2 distillate
oil (0.0015% sulfur by weight or 15 ppm), #4 residual oil (0.25-0.5%
sulfur by weight), and #6 residual oil (0.3-0.5% sulfur by weight). On
October 25, 2010, New Jersey adopted a rule \65\ to modify the sulfur-
in-fuel limits in accordance with the MANE-VU Ask. This rule lowered
the sulfur content of all distillate fuel oils (#2 fuel oil and
lighter) to 15 ppm beginning on July 1, 2016. The sulfur content of #4
fuel oil was lowered to 2,500 ppm and for #6 fuel oil to a range of
3,000 to 5,000 ppm sulfur content beginning July 1, 2014.\66\ New
Jersey therefore concluded that it is meeting Ask 3.
---------------------------------------------------------------------------
\65\ SIP-approved N.J.A.C. 7:27-9 ``Sulfur in Fuels''.
\66\ The maximum sulfur content of #6 fuel oil varies depending
on the county where the fuel oil is burned. The northern part of New
Jersey has a lower maximum sulfur content for residual fuel oil at
3,000 ppm. While the southern part of New Jersey has a maximum
sulfur content of 5,000 ppm. See N.J.A.C. 7:27-9 et seq. https://www.nj.gov/dep/aqm/rules27.html.
---------------------------------------------------------------------------
MANE-VU Ask 4 requests states to update permits to ``lock in''
lower emissions rates for NOX, SO2, and PM at
emissions sources larger than 250 million British Thermal Units (MMBtu)
per hour heat input that have switched to lower emitting fuels. New
Jersey's SIP submissions explains that EGUs and other large point
emission sources that have switched operations to lower emitting fuels
are already locked into the lower emission rates for NOX,
SO2, and PM by permits, enforceable agreements, and/or
rules. These units are required to amend their permits through the New
Source Review (NSR) process if they plan to switch back to coal or
another fuel that will increase emissions. A change in fuel, unless
already allowed in the permit, would be a modification.\67\ N.J.A.C.
7:27-22 requires that an application to modify the permit be submitted
prior to the change in fuel; New Jersey's preconstruction and operating
permit programs are consolidated such that one permit application
serves both purposes. New Jersey therefore concluded it is meeting Ask
4.
---------------------------------------------------------------------------
\67\ See N.J.A.C 7:27-22.1, defining ``Modify'' or
``modification'' to ``mean[ ] any physical change in, or change in
the method of operation of, existing equipment or control apparatus
that increases the amount of actual emissions of any air contaminant
emitted by that equipment or control apparatus or that results in
the emission of any air contaminant not previously emitted. This
term shall not include normal repair and maintenance. A modification
may be incorporated into an operating permit through a significant
modification, a minor modification, or a seven-day-notice change.''
---------------------------------------------------------------------------
Ask 5 requests that MANE-VU states ``control NOX
emissions for peaking combustion turbines that have the potential to
operate on high electric demand days'' by either: (1) Meeting
NOX emissions standards specified in the Ask for turbines
that run on natural gas and fuel oil, (2) performing a four-factor
analysis for reasonable installation of or upgrade to emission
controls, or (3) obtaining equivalent emission reductions on high
electric demand days.\68\ The Ask requests states to strive for
NOX emission standards of no greater than 25 ppm for natural
gas and 42 ppm for fuel oil, or at a minimum, NOX emissions
standards of no greater than 42 ppm for natural gas and 96 ppm at for
fuel oil. New Jersey adopted regulations on March 20, 2009,\69\ to
control peaking combustion turbines that have the potential to operate
on high electric demand days,\70\ and the regulations were approved
into the SIP (75 FR 45483, August 3, 2010). New Jersey's SIP-approved
control levels require 0.75 pounds of NOX per MWh (25 ppmvd)
for natural gas, and 1.20 pounds of NOX per MWh (42 ppmvd)
for oil, for a combined cycle combustion turbine or a regenerative
cycle combustion turbine, and 1.00 pounds of NOX per MWh (25
ppmvd) for natural gas, and 1.60 pounds of NOX per MWh (42
ppmvd) for oil, for a simple cycle turbine combustion turbine.\71\ \72\
New Jersey therefore concluded it is meeting Ask 5.

electrical demands bring additional generation units online, many of
which are infrequently operated and may have significantly higher
emissions rates of the generation fleet.

The last Ask for states within MANE-VU (Ask 6) requests states to
report in their regional haze SIPs about programs that decrease energy
demand and increase the use of combined heat and power (CHP) and other
distributed generation technologies such as fuel cells, wind and solar.
New Jersey explains that on July 6, 2007, Governor Corzine signed the
Global Warming Response Act.\73\ The Act requires New Jersey to reduce
greenhouse gas emissions by 20 percent by 2020, and by 80 percent by
2050. Measures to meet these requirements will also help reduce
SO2, PM, and NOX emissions and improve
visibility. On January 29, 2018, Governor Phil Murphy signed an
Executive Order \74\ directing New Jersey's return to full
participation in the Regional Greenhouse Gas Initiative (RGGI).
Specifically, the Executive Order directs DEP to initiate rulemaking by
February 28, 2018. In addition, Governor Murphy sent a letter, dated
February 16, 2018, to the RGGI states notifying them of New Jersey's
intent to rejoin RGGI ``as a partner in reducing greenhouse gas
emissions, improving the health of residents, and growing the economy
in our region.'' New Jersey formally rejoined RGGI on June 17,
2019.\75\ \76\ RGGI is part of Governor Murphy's goal to achieve 100
percent clean energy by 2050. New Jersey's participation in RGGI will
shift the state's power sector towards clean and renewable energy
sources such as wind, solar, and fuel cells, and will help reduce
emissions and improve visibility. New Jersey therefore concluded it is
meeting Ask 6.

b. The EPA's Evaluation of New Jersey's Response to the Six MANE-VU
Asks and Compliance With Sec. 51.308(f)(2)(i)
The EPA is proposing to find that New Jersey has satisfied the
[[Page 51031]]
requirements of Sec. 51.308(f)(2)(i) related to evaluating sources and
determining the emission reduction measures that are necessary to make
reasonable progress by considering the four statutory factors. We are
proposing to find that New Jersey has satisfied the four-factor
analysis requirement through its analysis and actions to address MANE-
VU Asks 2 and 3. We also propose to find that New Jersey reasonably
concluded that it satisfied all six Asks.
As explained above, New Jersey relied on MANE-VU's technical
analyses and framework (i.e., the Asks) to select sources and form the
basis of its long-term strategy. MANE-VU conducted an inventory
analysis to identify the source sectors that produced the greatest
amount of SO2 and NOX emissions in 2011;
inventory data were also projected to 2018. Based on this analysis,
MANE-VU identified the top-emitting sectors for each of the two
pollutants, which for SO2 include coal-fired EGUs,
industrial boilers, oil-fired EGUs, and oil-fired area sources
including residential, commercial, and industrial sources. Major-
emitting sources of NOX include on-road vehicles, non-road
vehicles, and EGUs.\77\ The RPO's documentation explains that ``[EGUs]
emitting SO2 and NOX and industrial point sources
emitting SO2 were found to be sectors with high emissions
that warranted further scrutiny. Mobile sources were not considered in
this analysis because any ask concerning mobile sources would be made
to EPA and not during the intra-RPO and inter-RPO consultation process
among the states and tribes.'' \78\ EPA proposes to find that New
Jersey reasonably evaluated the two pollutants--SO2 and
NOX--that currently drive visibility impairment within the
MANE-VU region and that it adequately explained and supported its
decision to focus on these two pollutants through its reliance on the
MANE-VU technical analyses cited in its submission.
---------------------------------------------------------------------------
\77\ See appendix G ``Contribution Assessment--Final.''
\78\ See Appendix B ``Asks--Final.''
---------------------------------------------------------------------------
Section 51.308(f)(2)(i) requires states to evaluate and determine
the emission reduction measures that are necessary to make reasonable
progress by applying the four statutory factors to sources in a control
analysis. As explained previously, the MANE-VU Asks are a mix of
measures for sectors and groups of sources identified as reasonable for
states to address in their regional haze plans. While MANE-VU
formulated the Asks to be ``reasonable emission reduction strategies''
to control emissions of visibility impairing pollutants,\79\ EPA
believes that two of the Asks, in particular, engage with the
requirement that states determine the emission reduction measures that
are necessary to make reasonable progress through consideration of the
four factors. As laid out in further detail below, the EPA is proposing
to find that MANE-VU's four-factor analysis conducted to support the
emission reduction measures in Ask 3 (ultra-low sulfur fuel oil Ask),
in conjunction with New Jersey's supplemental analysis and explanation
of how it has complied with Ask 2 (perform four-factor analyses for
sources with potential for >=3.0 Mm-1 impacts) satisfy the
requirement of Sec. 51.308(f)(2)(i). The emission reduction measures
that are necessary to make reasonable progress must be included in the
long-term strategy, i.e., in New Jersey's SIP. 40 CFR 51.308(f)(2).
---------------------------------------------------------------------------
\79\ Id.
---------------------------------------------------------------------------
We acknowledge that MANE-VU and New Jersey provided information on
the four statutory factors for several source categories, including
EGUs, ICI boilers, cement and lime kilns, heating oil, and residential
wood combustion. See April 2021 Supplemental Information at 2; 2020 New
Jersey SIP Submission Appendix H-2. However, other than for Asks 2
(requesting four-factor analyses be conducted) and 3 (requesting
adoption of low-sulfur fuel oil), it is not apparent from the
documentation provided with New Jersey's SIP submission how the
measures included in each of the Asks are the result of consideration
of that information. See 40 CFR 51.308(f)(2)(i) (SIPs must include a
description of ``how the four factors were taken into consideration in
selecting the measures for inclusion in [the state's] long-term
strategy'').
As for Ask 1, New Jersey asserted that it satisfies Ask 1 because
its SIP-approved regulations applicable to EGU boilers include year-
round emission limits and because it already requires that controls be
run year-round for both NOX \80\ and SO2 by
setting emission limits in permits that reflect the emission levels
when the controls are run. New Jersey's SIP-approved (83 FR 50506,
October 9, 2018) NOX reasonably available control technology
(RACT) limits for boilers serving EGUs applies to any boiler serving an
electric generating unit and requires year-round controls. The New
Jersey RACT rule includes maximum allowable NOX emission
limits of 1.50 pounds per megawatt hour for coal boilers, 2.00 pounds
per megawatt hour for fuel oils heavier than No. 2 fuel oil and 1.00
pounds per megawatt hour for No. 2 and lighter fuel oil and gas only
fired boilers.\81\ New Jersey's SIP-approved sulfur limits include
year-round limits (75 FR 45483, August 3, 2010), (77 FR 19, January 3,
2012). Under these rules, any source that combusts solid fuel shall
emit SO2 at a 24-hour emission rate no greater than 0.250
pounds per 1,000,000 BTU gross heat input for every calendar day, and
at a 30-calendar-day rolling average emission rate no greater than
0.150 pounds per 1,000,000 BTU gross heat input.\82\ New Jersey set a
range of 24-hour emission limits for sources combusting fuel oils based
on location within the state and type of fuel oil. The emission limits
ranged from 0.00160 pounds per million BTU for No. 2 and lighter fuel
oil, regardless of location within the state to 0.530 pounds per
million BTU for No. 5, No. 6, and heavier fuel oils in certain part of
the state.\83\ New Jersey's SIP-approved SO2 and
NOX RACT requirements in N.J.A.C. 7:27-9, 7:27-10, and 7:27-
19, which include Subchapter 19.4 ``Boilers serving electric generating
units'' and Subchapter 19.5 ``Stationary combustion turbines,'' limit
SO2 and NOX emissions from EGUs consistent with
the year-round operation of control technologies. EPA thus proposes to
find that New Jersey reasonably concluded that has satisfied Ask 1.

Ask 2 addresses the sources MANE-VU determined have the potential
for larger than, or equal to, 3.0 Mm-1 visibility impact at
any MANE-VU Class I area; the Ask requests MANE-VU states to conduct
four-factor analyses for the specified sources within their borders.
This Ask explicitly engages with the statutory and regulatory
requirement to determine reasonable progress based on the four factors;
MANE-VU considered it ``reasonable to have the greatest contributors to
visibility impairment conduct a four-factor analysis that would
determine whether emission control measures should be pursued and what
would be reasonable for each source.'' \84\

---------------------------------------------------------------------------
As an initial matter, EPA does not necessarily agree that 3.0
Mm-1 visibility impact is a reasonable threshold for source
selection. The RHR recognizes that, due to the nature of regional haze
visibility impairment,
[[Page 51032]]
numerous and sometimes relatively small sources may need to be selected
and evaluated for control measures in order to make reasonable
progress. See 2021 Clarifications Memo at 4. As explained in the 2021
Clarifications Memo, while states have discretion to choose any source
selection threshold that is reasonable, ``[a] state that relies on a
visibility (or proxy for visibility impact) threshold to select sources
for four-factor analysis should set the threshold at a level that
captures a meaningful portion of the state's total contribution to
visibility impairment to Class I areas.'' 2021 Memo at 3. In this case,
the 3.0 Mm-1 threshold identified only one source in New
Jersey (and only 22 across the entire MANE-VU region), indicating that
it may be unreasonably high. However, while New Jersey did not select
additional sources that fell under MANE-VU's 3.0 Mm-1
threshold for four-factor analysis, it did provide supplemental
information and explanation supporting its decision not to do so.
MANE-VU identified two units at the BL England facility, a coal-
and oil-fired power plant, as having a 5.6 Mm-1 visibility
impact and thus meeting its threshold for four-factor analysis. New
Jersey's SIP submission indicates it had intended to perform a four-
factor analysis on BL England, however, the plant permanently shut down
and all permits were terminated prior to the state initiating that
analysis.\85\ The state then looked at other sources with visibility
impacts less than 3.0 Mm;-1 New Jersey explained that
emissions from the units it examined are well-controlled and most of
the units were found to have much lower visibility impacts).
The state's supplemental information \86\ indicates that next highest-
impacting EGU in New Jersey, Hudson Generating Station, ranked 74th in
MANE-VU's top impacting EGU stacks list and had a maximum extinction
impact of 0.91 Mm-1 based on 2015 emissions. The next
highest impacting stacks were at Mercer Generating Station, units 1 and
2, which ranked 223rd and 224th on the EGU list and had a maximum
extinction impact of approximately 0 Mm-1 based on 2015
emissions. The Hudson and Mercer Generating Stations shut down
permanently on June 1, 2017. At the time of SIP submission, the largest
remaining sources in the state of New Jersey were three coal boilers
operating at two cogeneration power plants, Logan Generating Plant and
Carneys Point. The two boilers at Carneys Point were equipped with
Selective Catalytic Reduction (SCR) controls, while the boiler at Logan
had both SCR and low-NOX burners with overfire air. The
units were subject to the SIP-approved NOX RACT
requirements, requiring year-round NOX control, and the SIP-
approved SO2 emission limits. In the most recent five-year
period for which EPA Air Markets Program Data (AMPD) are available
(2016-2020), the two boilers at Carneys Point averaged approximately
300 tons NOX emissions and an emission rate of 0.12 lb/
MMBtu. The boiler at Logan Generating Station averaged approximately
403 tons NOX and an emission rate of 0.11 lb/MMBtu. New
Jersey also examined the two facilities with ICI boilers that MANE-VU
flagged as contributing to visibility impairment at the Brigantine
Wilderness: Atlantic County Utilities Landfill (ACUA) and Gerresheimer
Moulded Glass (now Corning Pharmaceutical Glass). At the time of the
analysis, and due to their close proximity to the Class I area, these
boilers contributed 1.67 Mm-1 and 1.0 Mm-1 light
extinction, respectively.\87\ However, this was based on the sources'
2011 emission rates. Currently, there are no permitted ICI boilers at
these facilities. ACUA's 19 tpy SO2 in 2019 are considerably
lower than the 2011 emissions of 907.88 tpy of SO2. Corning
Pharmaceutical Glass's emissions have likewise changed significantly
since 2011, from 102.9 tpy of SO2 to 1.29 tpy SO2
in 2019. This was due to an error in the 2011 emissions that were
reported in the SIP. The 2019 emissions represent the actual state of
the facility.\88\

New Jersey reviewed its remaining sources on MANE-VU's top
impacting EGU stacks list and its remaining sources on MANE-VU's top
impacting ICI facilities list.\89\ New Jersey also addressed the six
facilities flagged by the NPS in their comment letter, which the NPS
identified based on the 2014 National Emissions Inventory (NEI)
emissions and a Q/d analysis. New Jersey listed the controls at each of
these facilities. The NPS list included Carneys Point and Logan
Generating Stations, the controls and emissions for which were
discussed previously. The list also included Paulsboro and Phillips
Bayway Refineries and Covanta Essex Company and Union County Resources
solid waste combustors and incinerators. For Paulsboro, emissions
controls include a scrubber, adsorber, particulate filter, thermal
oxidizer and other controls. The SO2 emissions at Paulsboro
were 56.45 tpy in 2014 and 23.85 tpy in 2017.\90\ The ICI boilers at
Paulsboro are subject to New Jersey's SIP-approved NOX RACT
limits of 0.10 pound per million BTU for natural gas fired ICI
boilers.\91\ For Phillips Bayway Refinery, the list of controls
included scrubbers, SCR, fabric filters, adsorbers, particulate
filters, cyclones, separators, and other controls. The SO2
emissions from Phillips were 81.98 tpy in 2014 and 41.12 tpy in
2017.\92\ Phillips, like Paulsboro, is subject to New Jersey RACT
limits for NOX. Covanta Essex has a scrubber, electrostatic
precipitator, particulate filter, selective non-catalytic reduction
(SNCR) and other controls. The SO2 emissions at Covanta were
110.73 tpy in 2014 and 58.68 tpy in 2017.\93\ Union County has a
scrubber, SNCR, particulate filter and other controls. The
SO2 emissions were 35.73 tpy in 2014 and 23.31 tpy in
2017.\94\ All municipal solid waste incinerators in New Jersey,
including Covanta and Union County, are subject to the SIP-approved
NOX RACT limits of 150 ppmvd.\95\

New Jersey also explained that it implements a range of
regulations, consent decrees, administrative consent orders, and
federal regulations to control NOX emissions, including SIP-
approved short-term performance standards for NOX emissions
from EGUs and measures to address EGU emissions on high electric demand
days; presumptive NOX limits for source categories including
EGU boilers, stationary combustion turbines, ICI boilers, stationary
reciprocating engines; and certain types of manufacturing facilities
and incinerators; and RACT rules for stationary reciprocating

---------------------------------------------------------------------------
The EPA proposes to find that New Jersey reasonably determined it
has satisfied Ask 2. As explained above, we do not necessarily agree
that a 3.0 Mm-1 threshold for selecting sources for four-
factor analysis results in a set of sources the evaluation of which has
the potential to meaningfully reduce the state's contribution to
visibility impairment. MANE-VU's threshold identified only one source
in New Jersey for four-factor analysis. However, in this particular
instance we propose to find that New Jersey's additional information
and explanation indicates that the state has in fact examined a
reasonable set of sources, including sources flagged by FLMs, and
reasonably concluded that four-factor analyses for its top-impacting
sources are not necessary because the outcome would be that no further
emission reductions would be reasonable. EPA is basing this proposed
finding on the state's examination of its largest operating EGU and ICI
sources, at the time of SIP submission, and on the emissions from and
controls that apply to those sources, as well as on New Jersey's
existing SIP-approved NOX and SO2 rules that
effectively control emissions from the largest contributing stationary-
source sectors.\97\
---------------------------------------------------------------------------

March 2020 Regional Haze SIP at 4-7.
---------------------------------------------------------------------------
Ask 3, which addresses the sulfur content of heating oil used in
MANE-VU states, is based on a four-factor analysis for the heating oil
sulfur reduction regulations contained in that Ask; \98\ specifically,
for the control strategy of reducing the sulfur content of distillate
oil to 15 ppm. The analysis started with an assessment of the costs of
retrofitting refineries to produce 15 ppm heating oil in sufficient
quantities to support implementation of the standard, as well as the
impacts of requiring a reduction in sulfur content on consumer prices.
The analysis noted that, as a result of previous EPA rulemakings to
reduce the sulfur content of on-road and non-road-fuels to 15 ppm,
technologies are currently available to achieve sulfur reductions and
many refiners are already meeting this standard, meaning that the
capital investments for further reductions in the sulfur content of
heating oil are expected to be relatively low compared to costs
incurred in the past. The analysis also examined, by way of example,
the impacts of New York's existing 15 ppm sulfur requirements on
heating oil prices and concluded that the cost associated with reducing
sulfur was relatively small in terms of the absolute price of heating
oil compared to the magnitude of volatility in crude oil prices. It
also noted that the slight price premium is compensated by cost savings
due to the benefits of lower-sulfur fuels in terms of equipment life
and maintenance and fuel stability. Consideration of the time necessary
for compliance with a 15 ppm sulfur standard was accomplished through a
discussion of the amount of time refiners had needed to comply with the
EPA's on-road and non-road fuel 15 ppm requirement, and the
implications existing refinery capacity and distribution infrastructure
may have for compliance times with a 15 ppm heating oil standard. The
analysis concluded that with phased-in timing for states that have not
yet adopted a 15 ppm heating oil standard there ``appears to be
sufficient time to allow refiners to add any additional heating oil
capacity that may be required.'' \99\ The analysis further noted the
beneficial energy and non-air quality environmental impacts of a 15 ppm
sulfur heating oil requirement and that reducing sulfur content may
also have a salutary impact on the remaining useful life of residential
furnaces and boilers.\100\

\98\ See appendix H2 ``FINAL Updates to Assessment of Reasonable
Progress for Regional Haze--Final'' at 8-4.
\99\ Id. see 8-7.
\100\ Id. see 8-8.
---------------------------------------------------------------------------
The EPA proposes to find that New Jersey reasonably relied on MANE-
VU's four-factor analysis for a low-sulfur fuel oil regulation, which
engaged with each of the statutory factors and explained how the
information supported a conclusion that a 15 ppm-sulfur fuel oil
standard for fuel oils is reasonable. New Jersey's SIP-approved ultra-
low sulfur fuel oil rule \101\ is consistent with Ask 3's sulfur
content standards for the three types of fuel oils (distillate oil, #4
residual oil, #6 residual oil). EPA therefore proposes to find that New
Jersey reasonably determined that it has satisfied Ask 3.
---------------------------------------------------------------------------
\101\ N.J.A.C. 7:27-9: Sulfur in Fuels (42 N.J.R. 2244) was
approved into New Jersey's SIP by the EPA on January 3, 2012. (77 FR
19, January 3, 2012).
---------------------------------------------------------------------------
New Jersey concluded that no additional updates were needed to meet
Ask 4, which requests that MANE-VU states pursue updating permits,
enforceable agreements, and/or rules to lock-in lower emission rates
for sources larger than 250 MMBtu per hour that have switched to lower
emitting fuels. As explained above, New Jersey has asserted that EGUs
and other large point emission sources that have switched operations to
lower emitting fuels are already locked into the lower emission rates
for NOX, SO2, and PM by permits, enforceable
agreements and/or rules. New Jersey's SIP-approved NOX RACT
rule limits the capability of a subject facility to switch to higher
emitting fuels.\102\ Furthermore, New Jersey's SIP-approved sulfur
regulations make it so that any source that combusts solid fuel and
that is constructed, installed, reconstructed or modified, is also
subject to New Jersey's state-of-the-art requirements,\103\ lowest
achievable emission rate requirements,\104\ and best available control
technology requirements at 40 CFR 52.21. In addition, modified units in
New Jersey are required to amend their permits through the New Source
Review (NSR) process if they plan to switch back to coal or a fuel that
will increase emissions. A change in fuel, unless already allowed in
the permit, would be a modification.\105\ New Jersey's operating
permits regulations require that an application to modify the permit be
submitted prior to the change in fuel.\106\ Thus, given the permitting
and regulatory requirements outlined above, including the fact that
sources that have switched fuel are required to revise their permits to
reflect the change, that state rules make any proposed reversion
difficult by requiring permitting and other control analyses, including
NSR, the EPA proposes to find that New Jersey reasonably determined it
has satisfied Ask 4.

emitted by that equipment or control apparatus or that results in
the emission of any air contaminant not previously emitted. This

Ask 5 addresses NOX emissions from peaking combustion
turbines that have the potential to operate on high electric demand
days. New Jersey explains that it has SIP-approved regulations \107\ to
[[Page 51034]]
control peaking combustion turbines \108\ that have the potential to
operate on high electric demand days.\109\ The Ask requests states to
strive for NOX emission standards of no greater than 25 ppm
for natural gas and 42 ppm for fuel oil, or at a minimum,
NOX emissions standards of no greater than 42 ppm for
natural gas and 96 ppm at for fuel oil. The control levels adopted by
New Jersey are below those requested by this Ask. Because no peaking
combustion turbine within the state is permitted to emit more than 25
ppm for natural gas and 42 ppm for fuel oil,\110\ EPA proposes to find
that New Jersey reasonably concluded that its existing regulations
comply with Ask 5.
---------------------------------------------------------------------------
\107\ See N.J.A.C. 7:27-19: Control and Prohibition of Air
Pollution from Oxides of Nitrogen https://www.state.nj.us/dep/aqm/currentrules/Sub19.pdf.
\108\ Peaking combustion turbine is defined for the purpose of
this Ask as a turbine capable of generating 15 megawatts or more,
that commenced operation prior to May 1, 2007, is used to generate
electricity all or part of which is delivered to electric power
distribution grid for commercial sale and that operated less than or
equal to an average of 1,752 hours (or 20%) per year during 2014 to
2016.
\109\ High electric demand days are days when higher than usual
electrical demands bring additional generation units online, many of
which are infrequently operated and may have significantly higher
emissions rates of the generation fleet.
\110\ See docket documents ``Existing Combined Cycle Turbines''
and ``Existing Simple Cycle Turbines'' for further information.
---------------------------------------------------------------------------
Finally, with regard to Ask 6, New Jersey explains the greenhouse
gas initiatives and clean energy requirements within the state
including promulgation of the ``Global Warming Response Act'' codified
at N.J.S.A 26:2C-37 and issuance of Executive Orders directing
rulemaking, and re-joining RGGI.''. The EPA is proposing to find that
New Jersey has satisfied Ask 6's request to consider and report in its
SIP measures or programs related to energy efficiency, cogeneration,
and other clean distributed generation technologies.
In sum, the EPA is proposing to find that--based on New Jersey's
participation in the MANE-VU planning process, how it has addressed
each of the Asks, its supplemental information and explanation
regarding NOX sources and emissions, and the EPA's
additional assessment of New Jersey's emissions and point sources--New
Jersey has complied with the requirements of Sec. 51.308(f)(2)(i).
Specifically, MANE-VU Asks 2 and 3 engage with the requirement that
states evaluate and determine the emission reduction measures that are
necessary to make reasonable progress by considering the four statutory
factors. While New Jersey did not select any sources for source-
specific four-factor analyses pursuant to Ask 2, EPA is proposing to
find the state's approach reasonable because it demonstrated that the
sources with the greatest modeled impacts on visibility, as well as
other sources that might be expected to impact visibility, either have
shut down, have reduced their emissions so significantly that it is
clear a four-factor analysis would not yield further reasonable
emission reductions, or are subject to stringent emission control
measures. New Jersey's SIP-approved control measures, emissions
inventory \111\ and information provided in response to comments \112\
demonstrate that the sources of SO2 and NOX
within the state that would be expected to contribute to visibility
impairment have small emissions of NOX and SO2,
are well controlled, or both. New Jersey's SIP-approved sulfur in fuel
limits sets stringent limits for sulfur content and SO2
emissions for both sulfur in solid fuels \113\ and sulfur in non-solid
fuels.\114\ New Jersey's SIP-approved NOX RACT regulations
include stringent limits on boilers serving EGUs, stationary combustion
turbines, ICI boilers and other indirect heat exchangers, stationary
reciprocating engines, asphalt pavement production plants, glass
manufacturing furnaces, emergency generators, MSW incinerators, sewage
sludge incinerators, high electric demand day units and other sources
of NOX. (83 FR 50506, October 9, 2018). Therefore, it is
reasonable to assume that selecting additional sources from MANE-VU's
or FLMs' lists for four-factor analysis would not have resulted in
additional emission reduction measures being determined to be necessary
to make reasonable progress for the second implementation period.
---------------------------------------------------------------------------
\111\ See appendix E1 ``Selection of States for MANE-VU Regional
Haze Consultation (2018)--Final'' and ``Supplemental Information for
New Jersey's March 2020 Regional Haze SIP.''

239.
\113\ See N.J.A.C. 7:27-10 ``Sulfur in Solid Fuels''.
\114\ See N.J.A.C. 7:27-9 ``Sulfur in Fuels''.
---------------------------------------------------------------------------
Additionally, MANE-VU conducted a four-factor analysis to support
Ask 3, which requests that states pursue ultra-low sulfur fuel oil
standards to address SO2 emissions. New Jersey has done so
and included its regulations in its SIP. This also contributes to
satisfying the requirements that states determine the emission
reduction measures that are necessary to make reasonable progress by
considering the four factors, and that their long-term strategies
include the enforceable emission limitations, compliance schedules, and
other measures necessary to make reasonable progress. To the extent
that MANE-VU and New Jersey regard the measures in Asks 1 and 4 through
6 as being part of the region's strategy for making reasonable
progress, we propose to find it reasonable for New Jersey to address
these Asks by pointing to existing measures that satisfy each.
c. Additional Long-Term Strategy Requirements
The consultation requirements of Sec. 51.308(f)(2)(ii) provides
that states must consult with other states that are reasonably
anticipated to contribute to visibility impairment in a Class I area to
develop coordinate emission management strategies containing the
emission reductions measures that are necessary to make reasonable
progress. Section 51.308(f)(2)(ii)(A) and (B) require states to
consider the emission reduction measures identified by other states as
necessary for reasonable progress and to include agreed upon measures
in their SIPs, respectively. Section 51.308(f)(2)(ii)(C) speaks to what
happens if states cannot agree on what measures are necessary to make
reasonable progress.
New Jersey participated in and provided documentation of the MANE-
VU intra- and inter-RPO consultation processes and addressed the MANE-
VU Asks by providing information on the measures it has in place that
satisfy each Ask.\115\ MANE-VU also documented disagreements that
occurred during consultation. MANE-VU noted in their Consultation
Report that upwind states expressed concern regarding the analyses the
RPO utilized for the selection of states for the consultation. MANE-VU
agreed that these tools, as all models, have their limitations, but
nonetheless deemed them appropriate. Additionally, there were several
comments regarding the choice of the 2011 modeling base year. MANE-VU
agreed that the choice of base year is critical to the outcome of the
study. MANE-VU acknowledged that there were newer versions of the
emission inventories and the need to use the best available inventory
for each analysis. However, MANE-VU disagreed that the choice of these
inventories was not appropriate for the analysis. Upwind states also
suggested that MANE-VU states adopt the 2021 timeline for regional haze
SIP submissions for the second planning period. MANE-VU agreed with the
reasons the comments provided, such as collaboration with data and
planning efforts. However, MANE-VU disagreed that the 2018
[[Page 51035]]
timeline would prohibit collaboration. Additionally, upwind states
noted that they would not be able to address the MANE-VU Asks until
they finalize their SIPs. MANE-VU believed the assumption of the
implementation of the Asks from upwind states in its 2028 control case
modeling was reasonable, however New Jersey did include the 2028 base
case and control case modeling in their SIP, representing visibility
conditions at Brigantine Wilderness assuming upwind states do not and
do implement the Asks, respectively. Additionally, New Jersey received
comments from Virginia, West Virginia, North Carolina, and Alabama on
their proposed regional haze SIP documenting those states' disagreement
with the MANE-VU Asks. In their response to comments, New Jersey noted
that it understands that states will conduct their own regional haze
analysis to determine long term strategies to pursue in their SIPs and
that New Jersey believes the MANE-VU Asks are reasonable and provide
them to upwind states for consideration.\116\
---------------------------------------------------------------------------
\115\ See appendix D ``MANE-VU Regional Haze Consultation Report
and Consultation Documentation--Final.''
\116\ See Appendix K ``Public Participation--Final''.
---------------------------------------------------------------------------
In sum, New Jersey participated in the MANE-VU intra- and inter-RPO
consultation and satisfied the MANE-VU Asks, satisfying Sec.
51.308(f)(2)(ii)(A) and (B). New Jersey satisfied Sec.
51.308(f)(2)(ii)(C) by participating in MANE-VU's consultation process,
which documented the disagreements between the upwind states and MANE-
VU and explained MANE-VU's reasoning on each of the disputed issues.
Based on the entirety of MANE-VU's intra- and inter-RPO consultation
and both MANE-VU's and New Jersey's responses to states' comments on
the SIP submission and various technical analyses therein, we propose
to determine that New Jersey has satisfied the consultation
requirements of Sec. 51.308(f)(2)(ii).
The documentation requirement of Sec. 51.308(f)(2)(iii) provides
that states may meet their obligations to document the technical bases
on which they are relying to determine the emission reductions measures
that are necessary to make reasonable progress through an RPO, as long
as the process has been ``approved by all State participants.'' As
explained above, New Jersey chose to rely on MANE-VU's technical
information, modeling, and analysis to support development of its long-
term strategy. The MANE-VU technical analyses on which New Jersey
relied are listed in the state's SIP submission and include source
contribution assessments, information on each of the four factors and
visibility modeling information for certain EGUs, and evaluations of
emission reduction strategies for specific source categories. New
Jersey also provided supplemental information to further demonstrate
the technical bases and emission information on which it relied on to
determine the emission reductions measures that are necessary to make
reasonable progress. Based on the documentation provided by the state,
we propose to find New Jersey satisfies the requirements of Sec.
51.308(f)(2)(iii).
Section 51.308(f)(2)(iii) also requires that the emissions
information considered to determine the measures that are necessary to
make reasonable progress include information on emissions for the most
recent year for which the state has submitted triennial emissions data
to the EPA (or a more recent year), with a 12-month exemption period
for newly submitted data. New Jersey's SIP submission included 2014 NEI
emission data for NOX, SO2, PM, VOCs and
NH3 and 2017 Air Markets Program Data (AMPD) emissions for
NOX and SO2. New Jersey's supplemental
information included 2019 AMPD and 2017 NEI emission data for
NOX.\117\ Further, EPA supplemented the submission by adding
a spreadsheet that includes all NEI emissions through 2017 for further
clarification.\118\ Based on New Jersey's consideration and analysis of
the 2017 and 2019 emission data in their SIP submittal and supplemental
documentation, the EPA proposes to find that New Jersey has satisfied
the emissions information requirement in 51.308(f)(2)(iii).
---------------------------------------------------------------------------
\117\ See docket document ``New Jersey Air Pollutant Emissions
Trends Data''.

---------------------------------------------------------------------------
We also propose to find that New Jersey reasonably considered the
five additional factors in Sec. 51.308(f)(2)(iv) in developing its
long-term strategy. Pursuant to Sec. 51.308(f)(2)(iv)(A), New Jersey
noted that existing and ongoing state and federal emission control
programs that contribute to emission reductions through 2028 would
impact emissions of visibility impairing pollutants from point and
nonpoint sources in the second implementation period. New Jersey
included in their SIP comprehensive lists of control measures with
their effective dates, pollutants addressed, and corresponding New
Jersey Administrative Code provisions.\119\

New Jersey's consideration of measures to mitigate the impacts of
construction activities as required by Sec. 51.308(f)(2)(iv)(B)
includes, in section 4.6.7.2 of its SIP submission, a list of measures
that New Jersey has implemented to mitigate the impacts from such
activities. New Jersey has implemented standards that reduce fugitive
dust emissions from construction,\120\ rules to address exhaust
emissions including rules to limit the idling of vehicles and
equipment,\121\ rules to reduce allowable smoke from on-road diesel
engines,\122\ and general conformity rules.\123\

Pursuant to Sec. 51.308(f)(2)(iv)(C), source retirements and

submission. Source retirements and replacements were considered in
developing the 2028 emission projections, with on the books/on the way
retirements and replacements included in the 2028 projections. The EGU
point sources included in the inventories used in the MANE-VU
contribution assessment and that were subsequently retired are
identified in Table 4-5.\124\ No non-EGU point source retirements in
New Jersey were considered when developing the 2028 emissions
projections.

In considering smoke management as required in 40 CFR
51.308(f)(2)(iv)(D), New Jersey explained, in section 4.6.7.4 of its
submission, that it addresses smoke management through its SIP-approved
Open Burning rules.\125\ Open Burn rules limit all types of open
burning within the state and require that, where open burning is
allowed, it is conducted only after obtaining an air pollution control
and Forest Fire Service permit. These rules have been in effect since
1956, with subsequent revisions further restricting open burning. The
rules prohibit open burning and have been successful in minimizing
burning throughout the
[[Page 51036]]
state. New Jersey also has several existing measures that help improve
visibility at Brigantine Wilderness Area and other Class I areas
impacted by emissions from New Jersey, including residential wood
burning outreach and education.\126\

New Jersey considered the anticipated net effect of projected
changes in emissions as required by 51.308(f)(2)(iv)(E) by discussing,
in section 4.6.7.5 of its submission, the photochemical modeling for
the 2018-2028 period it conducted in collaboration with MANE-VU. The
two modeling cases run were a 2028 base case, which considered only on-
the-books controls, and a 2028 control case that considered
implementation of the MANE-VU Ask. New Jersey presented the differences
between the base and control cases on the 20% most impaired and 20%
clearest days for each MANE-VU Class I area and explained that,
``[e]ven though the visibility improvement between [the cases] is
small, states are expected to do their part to ensure incremental
progress towards the 2064 visibility goal.'' \127\
---------------------------------------------------------------------------
\127\ NJ Regional Haze SIP--Final March 2020 at 38.
---------------------------------------------------------------------------
Because New Jersey has reasonably considered each of the five
additional factors the EPA proposes to find that New Jersey has
satisfied the requirements of 40 CFR 51.308(f)(2)(iv).
F. Reasonable Progress Goals
Section 51.308(f)(3) contains the requirements pertaining to RPGs
for each Class I area. Because New Jersey is host to a Class I area, it
is subject to both Sec. 51.308(f)(3)(i) and, potentially, to (ii).
Sec. 51.308(f)(3)(i) requires a state in which a Class I area is
located to establish RPGs--one each for the most impaired and clearest
days--reflecting the visibility conditions that will be achieved at the
end of the implementation period as a result of the emission
limitations, compliance schedules and other measures required under
paragraph (f)(2) to be in states' long-term strategies, as well as
implementation of other CAA requirements. The long-term strategies as
reflected by the RPGs must provide for an improvement in visibility on
the most impaired days relative to the baseline period and ensure no
degradation on the clearest days relative to the baseline period.
Section 51.308(f)(3)(ii) applies in circumstances in which a Class I
area's RPG for the most impaired days represents a slower rate of
visibility improvement than the uniform rate of progress calculated
under 40 CFR 51.308(f)(1)(vi). Under Sec. 51.308(f)(3)(ii)(A), if the
state in which a mandatory Class I area is located establishes an RPG
for the most impaired days that provides for a slower rate of
visibility improvement than the URP, the state must demonstrate that
there are no additional emission reduction measures for anthropogenic
sources or groups of sources in the state that would be reasonable to
include in its long-term strategy. Section 51.308(f)(3)(ii)(B) requires
that if a state contains sources that are reasonably anticipated to
contribute to visibility impairment in a Class I area in another state,
and the RPG for the most impaired days in that Class I area is above
the URP, the upwind state must provide the same demonstration.
Table 3-1 of New Jersey's SIP submittal summarizes baseline
visibility conditions (i.e., visibility conditions during the baseline
period) for the most impaired and clearest days and the 2028 RPG for
the most impaired days for Brigantine Wilderness Area, as well as
information on natural visibility conditions, the rate of progress
described by the URP in 2017 and 2028, and the modeled 2028 base case
(representing visibility conditions in 2028 with existing controls).
These visibility conditions, as well as the 2028 reasonable progress
goal for the clearest days, are also included in Appendix I2 of New
Jersey's SIP submission.\128\ Baseline visibility conditions at
Brigantine were 14.33 and 27.43 deciviews for the clearest and most
impaired days, respectively. New Jersey's 2028 RPGs for the clearest
and most impaired days were set at 10.47 and 17.97 deciviews. Thus, New
Jersey's 2028 RPG for the clearest days constitutes an improvement over
baseline visibility conditions as well as an improvement over the
current (2013-2017) visibility conditions, which are 11.48 deciviews.
For the most impaired days, the 2028 RPG of 17.97 deciviews also
represents an improvement relative to both baseline visibility
conditions and current visibility conditions, which are 19.86
deciviews.
---------------------------------------------------------------------------
\128\ See Appendix I2 ``Appendix I2--MANEVU Trends 2004-17
Report 2nd SIP Metrics--December 2018 Update--Final''.
---------------------------------------------------------------------------
New Jersey explained that the 2028 RPGs assume that upwind states--
states that also contribute to visibility impairment at Brigantine--
will implement the MANE-VU Asks or other control measures that achieve
similar reductions.\129\ Section 51.308(f)(3)(i) specifies that RPGs
must reflect ``enforceable emissions limitations, compliance schedules,
and other measures required under paragraph (f)(2) of this section''
(emphasis added). EPA interprets this provision as requiring that only
emission reduction measures that states--including upwind states--have
determined to be necessary for reasonable progress and incorporated
into their long-term strategies be reflected in a Class I area's RPGs.
This ensures that RPGs include only those measures that are reasonably
certain to be implemented. However, New Jersey's 2028 RPGs include
measures for upwind states that, as of now, those states have not
determined to be necessary to make reasonable progress and not included
in their long-term strategies. New Jersey's RPGs thus do not represent
upwind states' long-term strategies and as a result is not
representative of what the RPGs should be set at. New Jersey's 2028
most impaired base case of 18.16 deciviews reflects the visibility
conditions that are projected to be achieved based on states' existing
measures. As such, EPA considers the 2028 modeled base case value of
18.16 deciviews to be a more appropriate, conservative estimate of the
RPG for the 20% most impaired visibility days. Irrespective of the
measures New Jersey assumed upwind states will implement, EPA expects
that the observed deciview value in 2028 will actually be equal to or
lower than the 18.16 deciview estimate due to numerous coal-fired
utility boilers in upwind states have recently retired or are expected
to retire under enforceable commitments before 2028. Even assuming the
conservative estimate of 18.16 deciviews on the most impaired days in
2028, though, the RPG would constitute improvement over the baseline
visibility conditions of 27.43 deciviews and the current (2013-2017)
visibility conditions of 19.86 deciviews. Therefore, the long-term
strategy and the reasonable progress goals provide for an improvement
in visibility for the most impaired days since the baseline period and
ensure no degradation in visibility for the clearest days since the
baseline period. 40 CFR 51.308(f)(3)(i).
---------------------------------------------------------------------------
\129\ Id.
---------------------------------------------------------------------------
As noted in the RHR at 40 CFR 51.308(f)(3)(iii), the reasonable
progress goals are not directly enforceable, but will be considered by
the Administrator in evaluating the adequacy of the measures in the
implementation plan in providing for reasonable progress towards
achieving natural visibility conditions at that area. Regardless of
whether we regard the 2028 RPG for the most impaired days to be 17.97
deciviews or 18.16 deciviews, the
[[Page 51037]]
regulatory purpose of the RPGs has been fulfilled because visibility
conditions at the Brigantine Wilderness have improved since the
baseline period. EPA is therefore proposing to find that New Jersey's
RPGs satisfy the applicable requirements and provide for reasonable
progress towards achieving natural conditions.
Table 3-1 of New Jersey's submission provides that the value of the
URP in 2028 for the Brigantine Wilderness Area is 20.74 deciviews. As
explained above, EPA considers a value of 18.16 deciviews to be a more
appropriate, conservative estimate of the 2028 RPG for the most
impaired days. Regardless of whether the 2028 RPG for the most impaired
days is 17.97 deciviews of 18.16 deciviews, New Jersey's RPG is below
the URP and the demonstration requirement under Sec.
51.308(f)(3)(ii)(A) is not triggered.
Under Sec. 51.308(f)(3)(ii)(B), a state that contains sources that
are reasonably anticipated to contribute to visibility impairment in a
Class I area in another state for which a demonstration by the other
state is required under 51.308(f)(3)(ii)(B) must demonstrate that there
are no additional emission reduction measures that would be reasonable
to include in its long-term strategy. New Jersey's SIP revision
included the modeled MANE-VU 2028 visibility projections at nearby
Class I areas.\130\ While these projections may not represent the final
RPGs for these Class I areas, all of the base case 2028 projections for
the most impaired days at these areas (Acadia, Brigantine, Great Gulf,
Lye Brook, Moosehorn, Dolly Sods and Shenandoah) are well below the
respective 2028 points on the URPs. Therefore, we propose it is
reasonable to assume that the demonstration requirement under Sec.
51.308(f)(3)(ii)(B) as it pertains to these areas will not be
triggered.
---------------------------------------------------------------------------
\130\ See Appendix I2 ``MANE-VU Trends 2004-17 Report 2nd SIP
Metrics--December 2018 Update--Final.''
---------------------------------------------------------------------------
The EPA proposes to determine that New Jersey has satisfied the
applicable requirements of 40 CFR 51.308(f)(3) relating to RPGs.
G. Monitoring Strategy and Other Implementation Plan Requirements
Section 51.308(f)(6) specifies that each comprehensive revision of
a state's regional haze SIP must contain or provide for certain
elements, including monitoring strategies, emissions inventories, and
any reporting, recordkeeping and other measures needed to assess and
report on visibility. A main requirement of this subsection is for
states with Class I areas to submit monitoring strategies for
measuring, characterizing, and reporting on visibility impairment.
Compliance with this requirement may be met through participation in
the Interagency Monitoring of Protected Visual Environments (IMPROVE)
network.
According to section 7.2 of New Jersey's SIP submission, the
IMPROVE monitor for the Brigantine Wilderness Area (indicated as BRIG1
in the IMPROVE monitoring network database) is located outside the
Edwin B. Forsythe National Wildlife Refuge Headquarters in Oceanville,
New Jersey. The monitoring station is located as close as practicable
to, but not within, the wilderness area to limit and protect the
ecological and biological resources of the wilderness area. The
proximity of the monitor to the wilderness area ensures that the air
monitoring data collected is representative of the air quality within
the wilderness area.
Section 51.308(f)(6)(i) requires SIPs to provide for the
establishment of any additional monitoring sites or equipment needed to
assess whether reasonable progress goals to address regional haze for
all mandatory Class I Federal areas within the state are being
achieved. Regional haze data for Brigantine Wilderness Area are
collected by an IMPROVE monitor that is operated and maintained by the
U.S. Fish and Wildlife Service. In 2007, NJDEP established, at the same
location, a monitoring station that measures trace level SO2
and PM2.5 using continuous and Federal reference methods for
sample collection. A visibility camera was also installed in 2007. This
station replaces the one previously located nearby at the Nacote Creek
Research station in Galloway Township.
Section 51.308(f)(6)(ii) requires SIPs to provide for procedures by
which monitoring data and other information are used in determining the
contribution of emissions from within the state to regional haze
visibility impairment at mandatory Class I Federal areas both within
and outside the state. New Jersey relied on the MANE-VU contribution
assessment analysis.\131\ The analysis included include Eulerian (grid-
based) source models, Lagrangian (air parcel-based) source dispersion
models, as well as a variety of data analysis techniques that include
source apportionment models, back trajectory calculations, and the use
of monitoring and inventory data.
---------------------------------------------------------------------------
\131\ See Appendix G for the contribution assessments.
---------------------------------------------------------------------------
Section 51.308(f)(6)(iii) does not apply to New Jersey, as it has a
Class I area.
Section 51.308(f)(6)(iv) requires the SIP to provide for the
reporting of all visibility monitoring data to the Administrator at
least annually for each Class I area in the state. As noted above, the
Brigantine Wilderness Area IMPROVE monitor is operated and maintained
by the U.S. Fish and Wildlife Service. The monitoring strategy for New
Jersey relies upon the continued availability of the IMPROVE network.
The IMPROVE monitor for the Brigantine Wilderness Area (indicated as
BRIG1 in the IMPROVE monitoring network database) is located outside
the Edwin B. Forsythe National Wildlife Refuge Headquarters in
Oceanville, New Jersey. New Jersey supports the continued operation of
the IMPROVE network through both state and Federal funding mechanisms.
Section 51.308(f)(6)(v) requires SIPs to provide for a statewide
inventory of emissions of pollutants that are reasonably anticipated to
cause or contribute to visibility impairment, including emissions for
the most recent year for which data are available and estimates of
future projected emissions. It also requires a commitment to update the
inventory periodically. New Jersey provides for emissions inventories
and estimates for future projected emissions by participating in the
MANE-VU RPO and complying with EPA's Air Emissions Reporting Rule
(AERR). In 40 CFR part 51, subpart A, the AERR requires states to
submit updated emissions inventories for criteria pollutants to EPA's
Emissions Inventory System (EIS) every three years. The emission
inventory data is used to develop the NEI, which provides for, among
other things, a triennial state-wide inventory of pollutants that are
reasonably anticipated to cause or contribute to visibility impairment.
Section 8 of New Jersey's submission includes tables of NEI data.
The source categories of the emissions inventories included are: (1)
Point sources, (2) nonpoint sources, (3) non-road mobile sources, and
(4) on-road mobile sources. The point source category is further
divided into AMPD point sources and non-AMPD point sources.\132\ New
Jersey included NEI emissions inventories for the following years: 2002
(one of the regional haze program baseline years),
[[Page 51038]]
2008, 2011, 2014, and 2017; \133\ and for the following pollutants:
SO2, NOX, PM10, PM 2.5, VOCs, CO, and
NH3. New Jersey also provided a summary of SO2
and NOX emissions for AMPD sources for the years of 2016,
2017, 2018, and 2019.\134\
---------------------------------------------------------------------------
\132\ AMPD sources are facilities that participate in EPA's
emission trading programs. The majority of AMPD sources are electric
generating units (EGUs).
\133\ See docket document ``Supplemental Information for New
Jersey's March 2020 Regional Haze SIP'' for the 2017 NEI data.
\134\ See docket document ``Supplemental Information for New
Jersey's March 2020 Regional Haze SIP'' for the 2018 and 2019 AMPD
data.
---------------------------------------------------------------------------
Section 51.308(f)(6)(v) also requires states to include estimates
of future projected emissions and include a commitment to update the
inventory periodically. New Jersey relied on the MANE-VU 2028 emissions
projections for MANE-VU states. MANE-VU completed two 2028 projected
emissions modeling cases--a 2028 base case that considers only on-the-
books controls and a 2028 control case that considers implementation of
the MANE-VU Asks.\135\
---------------------------------------------------------------------------
\135\ See appendix C ``OTC MANE-VU 2011 Based Modeling Platform
Support Document October 2018--Final.''
---------------------------------------------------------------------------
The EPA proposes to find that New Jersey has met the requirements
of 40 CFR 51.308(f)(6) as described above, including through its
continued participation in the IMPROVE network and the MANE-VU RPO and
its on-going compliance with the AERR, and that no further elements are
necessary at this time for New Jersey to assess and report on
visibility pursuant to 40 CFR 51.308(f)(6)(vi).
H. Requirements for Periodic Reports Describing Progress Towards the
Reasonable Progress Goals
Section 51.308(f)(5) requires that periodic comprehensive revisions
of states' regional haze plans also address the progress report
requirements of 40 CFR 51.308(g)(1) through (5). The purpose of these
requirements is to evaluate progress towards the applicable RPGs for
each Class I area within the state and each Class I area outside the
state that may be affected by emissions from within that state.
Sections 51.308(g)(1) and (2) apply to all states and require a
description of the status of implementation of all measures included in
a state's first implementation period regional haze plan and a summary
of the emission reductions achieved through implementation of those
measures. Section 51.308(g)(3) applies only to states with Class I
areas within their borders and requires such states to assess current
visibility conditions, changes in visibility relative to baseline
(2000-2004) visibility conditions, and changes in visibility conditions
relative to the period addressed in the first implementation period
progress report. Section 51.308(g)(4) applies to all states and
requires an analysis tracking changes in emissions of pollutants
contributing to visibility impairment from all sources and sectors
since the period addressed by the first implementation period progress
report. This provision further specifies the year or years through
which the analysis must extend depending on the type of source and the
platform through which its emission information is reported. Finally,
Sec. 51.308(g)(5), which also applies to all states, requires an
assessment of any significant changes in anthropogenic emissions within
or outside the state have occurred since the period addressed by the
first implementation period progress report, including whether such
changes were anticipated and whether they have limited or impeded
expected progress towards reducing emissions and improving visibility.
New Jersey's submission describes the status of measures of the
long-term strategy from the first implementation period. As a member of
MANE-VU, New Jersey considered the MANE-VU Asks and adopted
corresponding measures into its long-term strategy for the first
implementation period. The MANE-VU Asks were: (1) Timely implementation
of Best Available Retrofit Technology (BART) requirements; (2) EGU
controls including Controls at 167 Key Sources that most affect MANE-VU
Class I areas; (3) Low sulfur fuel oil strategy; and (4) Continued
evaluation of other control measures. New Jersey met all the identified
reasonable measures requested during the first implementation period.
During the first planning period for regional haze, programs that were
put in place focused on reducing sulfur dioxide (SO2)
emissions. The reductions achieved led to vast improvements in
visibility at the MANE-VU Federal Class I Areas due to reduced sulfates
formed from SO2 emissions. New Jersey lists in Table 4-4 an
expansive list of post 2011 control measures that help control the
emissions of VOCs, NOX, PM and SO2 from a wide
range of sources.\136\ New Jersey's SIP submission includes emission
data demonstrating the reductions achieved throughout the state through
implementation of the measures mentioned in Table 4-4. The state
included periodic emission data that demonstrates a decrease in VOCs,
NOX, PM and SO2 emissions throughout the state.
---------------------------------------------------------------------------
\136\ See Table 4-4: ``Control Measures Post 2011'' of New
Jersey's SIP submission.
---------------------------------------------------------------------------
The EPA proposes to find that New Jersey has met the requirements
of 40 CFR 51.308(g)(1) and (2) because its SIP submission describes the
measures included in the long-term strategy from the first
implementation period, as well as the status of their implementation
and the emission reductions achieved through such implementation.
New Jersey's SIP submission included summaries of the visibility
conditions and the trend of the 5-year averages through 2017 at the
class I Brigantine Wilderness area. The SIP submission included the 5-
year baseline (2000-2004) visibility conditions for the clearest and
most impaired days of 14.33 and 27.43 deciviews, respectively. The SIP
submission also included the current 5-year status (2013-2017) for the
clearest and most impaired days of 11.48 and 19.86 deciviews,
respectively.\137\ The SIP submission also illustrated in Figure 2-2
the visibility metrics levels at Brigantine Wilderness Area, including
the 5-year rolling average for the clearest and most impaired
days.\138\ EPA therefore proposes to find that New Jersey as satisfied
the requirements of 40 CFR 51.308(g)(3).
---------------------------------------------------------------------------
\137\ See Table 2-1'' ``Comparison of Natural, Baseline, and
Current Visibility Conditions in Deciviews for the 20 percent
Clearest and 20 percent Most Impaired at Brigantine Wilderness
Area'' of New Jersey's SIP submission.
\138\ See Appendix I ``Visibility Metrics--Final'' for
additional visibility metrics throughout the MANE-VU class I areas.
---------------------------------------------------------------------------
Pursuant to Sec. 51.308(g)(4), in chapter 8 of their submittal,
New Jersey provided a summary of emissions of NOX,
SO2, PM10, PM2.5, VOCs, and
NH3 from all sources and activities, including from point,
nonpoint, non-road mobile, and on-road mobile sources, for the time
period from 2002 to 2014. New Jersey also included AMPD data for
SO2 and NOX emissions for 2016 and 2017 in their
submission. Additional 2017 NEI and 2019 AMPD emission data for
NOX was included in the state's supplemental
information.\139\ Additionally, EPA has included a spreadsheet that
tracks New Jersey air pollutant emissions trends data through 2017 for
all NEI pollutants.\140\
---------------------------------------------------------------------------
\139\ See docket document ``Supplemental Information for New
Jersey's March 2020 Regional Haze SIP.''
\140\ See ``New Jersey Air Pollutant Emissions Trends Data'' in
the docket.
---------------------------------------------------------------------------
The reductions achieved by New Jersey emission control measures are
seen in the emissions inventory. Based on New Jersey's SIP submission,
their
[[Page 51039]]
supplemental information \141\ and the EPA-provided supplemental
information in the ``New Jersey Air Pollutant Emissions Trends Data''
spreadsheet included in the docket, NOX emissions have
continuously declined in New Jersey from 2002 through 2017, especially
in the point, nonroad and onroad mobile sectors. NOX
emissions are expected to continue to decrease as fleet turnover occurs
and the older more polluting vehicles and equipment are replaced by
newer, cleaner ones. During that period, onroad sources contributed
almost half of the emissions at 48%, followed by area sources at 23%.
Nonroad sources contributed 17% and point sources contributed the least
at 13%. Table 6 of the supplemental information shows additional
NOX emissions data from 2016 to 2019 for New Jersey's point
sources that report to EPA's AMPD.\142\
---------------------------------------------------------------------------
\141\ See ``Supplemental Information for New Jersey's March 2020
Regional Haze SIP.''
\142\ Id.
---------------------------------------------------------------------------
Emissions of SO2 have shown a steady significant decline
in New Jersey over the period 2002 to 2017, particularly in the point,
nonroad and onroad mobile sectors.\143\ Reductions in point emissions
are primarily due to the acid rain program, New Jersey power plant
consent decrees and regulations, and Federal and State low sulfur fuel
regulations.\144\ Additionally, some of these decreases are
attributable to the MANE-VU low sulfur fuel strategy and the 90% or
greater reduction in SO2 emissions at 167 EGU stacks, both
inside and outside of MANE-VU, requested in the ``Non-MANE-VU Ask'' for
states within MANE-VU for the first regional haze planning period.\145\
Since some components of the MANE-VU low sulfur fuel strategy have
milestones of 2016 and 2018, and as MANE-VU states continue to adopt
rules to implement the strategy, additional SO2 emissions
reductions have likely been obtained since 2017 and are expected to
continue into the future.

In New Jersey's submission, table 8-7 shows a summary of
PM10 emissions from all NEI data categories point, nonpoint,
non-road, and onroad for the period from 2002 to 2014 in New Jersey. In
New Jersey, PM10 emissions steadily decreased in the point,
nonpoint, and nonroad categories for the period from 2002 to 2014. The
variations in the onroad are due to changes in emission inventory
calculation methodologies, which resulted in higher particulate matter
estimates in the other years than in 2002. The large variation in
emissions in the nonpoint category is due to changes in calculation
methodologies for residential wood burning and fugitive dust
categories, which have varied significantly.
Table 8-10 of New Jersey's submission shows a summary of
PM2.5 emissions from all NEI data categories for the period
from 2002 to 2014 in New Jersey. PM2.5 emissions steadily
decreased in the nonroad category for the period from 2002 to 2014. The
decrease in PM2.5 emissions is because of Federal new engine
standards for nonroad vehicles and equipment. There is an overall
decrease in onroad emissions due to Federal and State regulations. The
increase in emissions in the onroad category from 2002 to 2008 is due
to changes in emission inventory calculation methodologies and a model
change, as previously explained, which resulted in higher fine
particulate matter estimates in the years after 2002. The large
variation in emissions in the nonpoint category is due to changes in
calculation methodologies for residential wood burning and fugitive
dust categories, which have varied significantly. The other large
decrease in PM2.5 emissions is primarily due to the decrease
in emissions from fuel combustion at EGU and Industrial stationary
sources, with the emissions dropping from 5,269 tpy in 2008 to 1,528
tpy in 2017.
Table 8-21 of New Jersey's submission shows VOC emissions from all
NEI data categories for the period 2002 to 2014 in New Jersey. VOC
emissions have shown a steady decline in New Jersey over the period
2002 to 2014. VOC decreases were achieved in all sectors due to Federal
new engine standards for onroad and nonroad vehicles and equipment, the
National and State low emission vehicle programs, SIP-approved area
source rules such as consumer products, portable fuel containers,
paints, autobody refinishing, asphalt paving applications, and solvent
cleaning operations, and point source controls such as refinery consent
decrees and New Jersey's VOC storage tank rule.
Table 8-24 of New Jersey's submission shows ammonia
(NH3) emissions from all NEI data categories for the period
2002 to 2014 in New Jersey. Ammonia decreases were achieved in the
onroad and nonroad sectors due to Federal new engine standards for
vehicles and equipment. Point source increases from 2002 to 2008 are
due to reporting, grouping and methodology changes, not actual emission
increases. NH3 emissions were not reported to New Jersey's
emission statements program in 2002, therefore, they were estimated by
EPA. Reporting to New Jersey's emission statement program began in
2003. Nonpoint increases and decreases from 2002 to 2014 are due to
reporting, grouping and methodology changes. Overall, ammonia emissions
have decreased from 2008 to 2014. Emissions from 2002-2008 are not
comparable to post-2008 emissions due to methodology changes.
The EPA is proposing to find that New Jersey has satisfied the
requirements of Sec. 51.308(g)(4) by providing emissions information
for NOX, SO2, PM10, PM2.5,
VOCs, and NH3 broken down by type of source.
New Jersey uses the emissions trend data in the SIP submission
\146\ and the supplemental information \147\ provided to support the
assessment that anthropogenic haze-causing pollutant emissions in New
Jersey have decreased during the reporting period and that changes in
emissions have not limited or impeded progress in reducing pollutant
emissions and improving visibility, New Jersey's 2017 emission
inventories for NOX, SO2, PM10,
PM2.5, VOCs, and NH3 were lower than their 2014
emission inventories for those same pollutants emissions.\148\ The EPA
is proposing to find that New Jersey has met the requirements of Sec.
51.308(g)(5).

I. Requirements for State and Federal Land Manager Coordination
Section 51.308(i)(2)'s FLM consultation provision requires a state
to provide FLMs with an opportunity for consultation that is early
enough in the state's policy analyses of its emission reduction
obligation so that information and recommendations provided by the
FLMs' can meaningfully inform the state's decisions on its long-term
strategy. If the consultation has taken place at least 120 days before
a public hearing or public comment period, the opportunity for
consultation will be deemed early enough, Regardless, the opportunity
for consultation must be provided at least
[[Page 51040]]
sixty days before a public hearing or public comment period at the
state level. Section 51.308(i)(2) also provides two substantive topics
on which FLMs must be provided an opportunity to discuss with states:
assessment of visibility impairment in any Class I area and
recommendations on the development and implementation of strategies to
address visibility impairment. Section 51.308(i)(3) requires states, in
developing their implementation plans, to include a description of how
they addressed FLMs' comments.
The states in the MANE-VU RPO conducted FLM consultation early in
the planning process concurrent with the state-to-state consultation
that formed the basis of the RPO's decision making process. As part of
the consultation, the FLMs were given the opportunity to review and
comment on the technical documents developed by MANE-VU. The FLMs were
invited to attend the intra- and inter-RPO consultations calls among
states and at least one FLM representative was documented to have
attended seven intra-RPO meetings and all inter-RPO meetings. New
Jersey participated in these consultation meetings and calls.\149\
---------------------------------------------------------------------------
\149\ See Appendix D ``MANE-VU Regional Haze Consultation Report
and Consultation Documentation--Final.''
---------------------------------------------------------------------------
As part of this early engagement with the FLMs, on April 12, 2018,
the NPS sent letters to the MANE-VU states requesting that they
consider specific individual sources in their long-term
strategies.\150\ NPS used an analysis of emissions divided by distance
(Q/d) to estimate the impact of MANE-VU facilities. To select the
facilities, NPS first summed 2014 NEI NOX, PM10,
SO2, and SO4 emissions and divided by the
distance to a specified NPS mandatory Class I Federal area. NPS summed
the Q/d values across all MANE-VU states relative to Acadia, Mammoth
Cave and Shenandoah National Parks, ranked the Q/d values relative to
each Class I area, created a running total, and identified those
facilities contributing to 80% of the total impact at each NPS Class I
area. NPS applied a similar process to facilities in Maine relative to
Acadia National Park. NPS merged the resulting lists of facilities and
sorted them by their states. NPS suggested that a state consider those
facilities comprising 80% of the Q/d total, not to exceed the 25 top
ranked facilities. The NPS identified 10 facilities in New Jersey in
this letter.\151\ New Jersey included the NPS initial letter in their
proposed SIP. In a subsequent letter dated October 22, 2018, NPS
identified six facilities for which more control information was
desired. New Jersey detailed the emission controls and updates to the
six facilities to address the NPS's request for more information, as
discussed previously.\152\

On May 30, 2019, New Jersey submitted a draft Regional Haze SIP to
the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the
National Park Service for a 60-day review and comment period pursuant
to 40 CFR 51.308(i)(2).\153\ New Jersey received comments from the
Forest Service on July 23, 2019, and from the National Park Service on
July 26, 2019. New Jersey responded to the FLM comments and included
the responses in appendix K of their submission to EPA, in accordance
with Sec. 51.308(i)(3). Notices of the proposed SIP, availability and
the public hearing were published on NJDEP's website and issued on
three NJDEP air quality listservs on August 22, 2019. In addition,
interested parties not on the NJDEP's listservs were emailed the
notice, along with air quality contacts from other states, air quality
regional organizations and the EPA. A public hearing on the proposed
SIP revision was held on September 25, 2019, at the NJDEP office.
Written comments relevant to the proposal were accepted until the close
of business October 22, 2019.

For the reasons stated above, the EPA proposes to find that New
Jersey has satisfied the requirements under 40 CFR 51.308(i) to consult
with the FLMs on its regional haze SIP for the second implementation
period.
New Jersey's March 2020 SIP submission includes a commitment to
revise and submit a regional haze SIP by July 31, 2028, and every ten
years thereafter. The state's commitment includes submitting periodic
progress reports in accordance with Sec. 51.308(f) and a commitment to
evaluate progress towards the reasonable progress goal for each
mandatory Class I Federal area located within the state and in each
mandatory Class I Federal area located outside the state that may be
affected by emissions from within the state in accordance with Sec.
51.308(g).\154\

V. Proposed Action
The EPA is proposing to approve New Jersey's March 26, 2020 SIP
submission, supplemented on September 8, 2020, and April 1, 2021, as
satisfying the regional haze requirements for the second implementation
period contained in 40 CFR 51.308(f).
VI. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, EPA's role is to approve state choices,
provided that they meet the criteria of the CAA. 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 proposed 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).
In addition, this proposed rulemaking action, pertaining to New
Jersey regional haze SIP submission for the second
[[Page 51041]]
planning period, is not approved to apply on any Indian reservation
land or in any other area where the 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).
