Approval and Promulgation of Air Quality Implementation Plans; 
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.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R02-
OAR-2020-0432 at https://www.regulations.gov. For comments submitted at

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.

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\

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

    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:

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\
---------------------------------------------------------------------------

    \84\ See Appendix D ``MANE-VU Regional Haze Consultation Report 
and Consultation Documentation--Final.''
---------------------------------------------------------------------------

    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\

approved short-term performance standards for NOX emissions

days; presumptive NOX limits for source categories including 
EGU boilers, stationary combustion turbines, ICI boilers, stationary

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

    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\
---------------------------------------------------------------------------

    \97\ See April 2021 Supplemental Information for New Jersey's 
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\

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

    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.

    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.

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.

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.

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

    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).

    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 
replacement schedules are addressed in section 4.6.7.3 of New Jersey's 
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).
---------------------------------------------------------------------------

Current Visibility Conditions in Deciviews for the 20 percent

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\

their

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\

    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).
