IV. Statutory and Executive Order
Reviews
Under the Clean Air Act, the
Administrator is required to approve a
SIP submission that complies with the
provisions of the Act and applicable
federal regulations. 42 U.S.C. 7410(k);
40 CFR 52.02(a). Thus, in reviewing SIP
submissions, the EPA’s role is to
approve state choices, provided that
they meet the criteria of the Clean Air
Act. Accordingly, this proposed 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);
• Is not an Executive Order 13771 (82
FR 9339, February 2, 2017) regulatory
action because SIP approvals are
exempted under Executive Order 12866;
• 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
VerDate Sep<11>2014

Jkt 250001
application of those requirements would
be inconsistent with the Clean Air Act;
and
• Does not provide the EPA with the
discretionary authority to address
disproportionate human health or
environmental effects with practical,
appropriate, and legally permissible
methods under Executive Order 12898
(59 FR 7629, February 16, 1994).
In addition, the SIP 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 rules do 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).

SUPPLEMENTARY INFORMATION: On
February 27, 2020, DEP submitted a
revision to the Pennsylvania SIP to
incorporate a plan for maintaining the
1997 ozone NAAQS through July 25,
2027 in accordance with CAA section
175A. The submittal is titled, ‘‘State
Implementation Plan Revision: Second
Maintenance Plan for the HarrisburgLebanon-Carlisle 1997 8-Hour Ozone
Nonattainment Area,’’ which will be
referred to as the ‘‘Harrisburg-LebanonCarlisle Area second maintenance plan’’
throughout this document.
DATES:
I. Background
In 1979, under section 109 of the
CAA, EPA established primary and
secondary NAAQS for ozone at 0.12
parts per million (ppm), averaged over
E:\FR\FM\03SEP1.SGM
03SEP1
Federal Register / Vol. 85, No. 172 / Thursday, September 3, 2020 / Proposed Rules

a 1-hour period. 44 FR 8202 (February
8, 1979). On July 18, 1997 (62 FR
38856).1 EPA revised the primary and
secondary NAAQS for ozone to set the
acceptable level of ozone in the ambient
air at 0.08 ppm, averaged over an 8-hour
period. EPA set the 1997 ozone NAAQS
based on scientific evidence
demonstrating that ozone causes
adverse health effects at lower
concentrations and over longer periods
of time than was understood when the
pre-existing 1-hour ozone NAAQS was
set.
Following promulgation of a new or
revised NAAQS, EPA is required by the
CAA to designate areas throughout the
nation as attaining or not attaining the
NAAQS. On June 15, 2004 (69 FR
23858), EPA designated the HarrisburgLebanon-Carlisle Area as a
nonattainment area for the 1997 ozone
NAAQS. The area, consisting of
Cumberland, Dauphin, Lebanon and
Perry Counties, was redesignated to
attainment on July 25, 2007 (72 FR
40749), and effective the same day.
Once a nonattainment area has three
years of complete and certified air
quality data that has been determined to
attain the NAAQS, and the area has met
the other criteria outlined in CAA
section 107(d)(3)(E),2 the state can
submit a request to EPA to redesignate
the area to attainment. Areas that have
been redesignated by EPA from
nonattainment to attainment are referred
to as ‘‘maintenance areas.’’ One of the
criteria for redesignation is to have an
approved maintenance plan, under CAA
section 175A. The maintenance plan
must demonstrate that the area will
continue to maintain the standard for
the period extending 10 years after
redesignation, and it must contain such
additional measures as necessary to
ensure maintenance as well as
contingency measures as necessary to
assure that violations of the standard
will be promptly corrected.
On July 25, 2007 (72 FR 40749
effective July 25, 2007), EPA approved
a redesignation request (and
1 In March 2008, EPA completed another review
of the primary and secondary ozone standards and
tightened them further by lowering the level for
both to 0.075 ppm. 73 FR 16436 (March 27, 2008).
Additionally, in October 2015, EPA completed a
review of the primary and secondary ozone
standards and tightened them by lowering the level
for both to 0.70 ppm. 80 FR 65292 (October 26,
2015).
2 The requirements of CAA section 107(d)(3)(E)
include attainment of the NAAQS, full approval
under section 110(k) of the applicable SIP,
determination that improvement in air quality is a
result of permanent and enforceable reductions in
emissions, demonstration that the state has met all
applicable section 110 and part D requirements, and
a fully approved maintenance plan under CAA
section 175A.

maintenance plan) from DEP for the
Harrisburg-Lebanon-Carlisle area. In
accordance with section 175A(b), at the
end of the eighth year after the effective
date of the redesignation, the state must
also submit a second maintenance plan
to ensure ongoing maintenance of the
standard for an additional 10 years.
EPA’s final implementation rule for
the 2008 ozone NAAQS revoked the
1997 ozone NAAQS and provided that
one consequence of revocation was that
areas that had been redesignated to
attainment (i.e., maintenance areas) for
the 1997 ozone NAAQS no longer
needed to submit second 10-year
maintenance plans under CAA section
175A(b).3 However, in South Coast Air
Quality Management District v. EPA 4
(South Coast II), the United States Court
of Appeals for the District of Columbia
(D.C. Circuit) vacated EPA’s
interpretation that, because of the
revocation of the 1997 ozone standard,
second maintenance plans were not
required for ‘‘orphan maintenance
areas,’’ (i.e. the Harrisburg-LebanonCarlisle area) that had been redesignated
to attainment for the 1997 ozone
NAAQS and were designated attainment
for the 2008 ozone NAAQS. Thus, states
with these ‘‘orphan maintenance areas’’
under the 1997 ozone NAAQS must
submit maintenance plans for the
second maintenance period.
As previously discussed, CAA section
175A sets forth the criteria for adequate
maintenance plans. In addition, EPA
has published longstanding guidance
that provides further insight on the
content of an approvable maintenance
plan, explaining that a maintenance
plan should address five elements: (1)
An attainment emissions inventory; (2)
a maintenance demonstration; (3) a
commitment for continued air quality
monitoring; (4) a process for verification
of continued attainment; and (5) a
contingency plan. The 1992 Calcagni
Memo 5 provides that states may
generally demonstrate maintenance by
either performing air quality modeling
to show that the future mix of sources
and emission rates will not cause a
violation of the NAAQS or by showing
that future emissions of a pollutant and
its precursors will not exceed the level
of emissions during a year when the
area was attaining the NAAQS (i.e.,
attainment year inventory). See 1992
Calcagni Memo at p. 9. EPA further
clarified in three subsequent guidance

memos describing ‘‘limited maintenance
plans’’ (LMPs) 6 that the requirements of
CAA section 175A could be met by
demonstrating that the area’s design
value 7 was well below the NAAQS and
that the historical stability of the area’s
air quality levels showed that the area
was unlikely to violate the NAAQS in
the future. Specifically, EPA believes
that if the most recent air quality design
value for the area is at a level that is
below 85% of the standard, or in this
case below 0.071 ppm, then EPA
considers the state to have met the
section 175A requirement for a
demonstration that the area will
maintain the NAAQS for the requisite
period. Accordingly, on February 27,
2020, DEP submitted the HarrisburgLebanon-Carlisle Area second
maintenance plan, following the LMP
guidance, and demonstrating that the
area will maintain the 1997 ozone
NAAQS through July 25, 2027, i.e.,
through the entire 20-year maintenance
period.
II. Summary of SIP Revision and EPA
Analysis
DEP’s February 27, 2020 SIP submittal
outlines a plan for continued
maintenance of the 1997 ozone NAAQS
which addresses the criteria set forth in
the 1992 Calcagni Memo as follows.
A. Attainment Emissions Inventory
For maintenance plans, a state should
develop a comprehensive and accurate
inventory of actual emissions for an
attainment year which identifies the
level of emissions in the area which is
sufficient to maintain the NAAQS. The
inventory should be developed
consistent with EPA’s most recent
guidance. For ozone, the inventory
should be based on typical summer
day’s emissions of oxides of nitrogen
(NOX) and volatile organic compounds
(VOC), the precursors to ozone
formation. In the first maintenance plan
for the Harrisburg-Lebanon-Carlisle
Area, DEP used 2004 for the attainment
year inventory, because 2004 was one of
the years in the 2003–2005 three-year
period when the area first attained the
6 See ‘‘Limited Maintenance Plan Option for
Nonclassifiable Ozone Nonattainment Areas’’ from
Sally L. Shaver, Office of Air Quality Planning and
Standards (OAQPS), dated November 16, 1994;
‘‘Limited Maintenance Plan Option for
Nonclassifiable CO Nonattainment Areas’’ from
Joseph Paisie, OAQPS, dated October 6, 1995; and
‘‘Limited Maintenance Plan Option for
ModeratePM10 Nonattainment Areas’’ from Lydia
Wegman, OAQPS, dated August 9, 2001.
7 The ozone design value for a monitoring site is
the 3-year average of the annual fourth-highest daily
maximum 8-hour average ozone concentrations.
The design value for an ozone nonattainment area
is the highest design value of any monitoring site
in the area.

1997 ozone NAAQS.8 The HarrisburgLebanon-Carlisle Area continued to
monitor attainment of the 1997 ozone
NAAQS in 2014. Therefore, the
emissions inventory from 2014
represents emissions levels conducive
to continued attainment (i.e.,
maintenance) of the NAAQS. Thus, DEP
is using 2014 as representing attainment
level emissions for its second
maintenance plan. Pennsylvania used
2014 summer day emissions from EPA’s
2014 version 7.0 modeling platform as
the basis for the 2014 inventory
presented in Table 1.9

The data shown in Table 1 is based on
the 2014 National Emissions Inventory
(NEI) version 2.10 The inventory
addresses four anthropogenic emission
source categories: Stationary (point)
sources, stationary nonpoint (area)
sources, nonroad mobile, and onroad
mobile sources. Point sources are
stationary sources that have the
potential to emit (PTE) more than 100
tons per year (tpy) of VOC, or more than
50 tpy of NOX, and which are required
to obtain an operating permit. Data are
collected for each source at a facility
and reported to DEP. Examples of point
sources include kraft mills, electrical
generating units (EGUs), and
pharmaceutical factories. Nonpoint
sources include emissions from
equipment, operations, and activities
that are numerous and in total have
significant emissions. Examples include
emissions from commercial and
consumer products, portable fuel
containers, home heating, repair and
refinishing operations, and crematories.
The onroad emissions sector includes
emissions from engines used primarily
to propel equipment on highways and
other roads, including passenger
vehicles, motorcycles, and heavy-duty
diesel trucks. The nonroad emissions
sector includes emissions from engines
that are not primarily used to propel
transportation equipment, such as
generators, forklifts, and marine
pleasure craft.
EPA reviewed the emissions
inventory submitted by DEP and
proposes to conclude that the plan’s
inventory is acceptable for the purposes
of a subsequent maintenance plan under
CAA section 175A(b).
In order to attain the 1997 ozone
NAAQS, the three-year average of the
fourth-highest daily average ozone
concentrations (design value, or ‘‘DV’’)
at each monitor within an area must not
exceed 0.08 ppm. Based on the
rounding convention described in 40
CFR part 50, appendix I, the standard is
attained if the DV is 0.084 ppm or
below. CAA section 175A requires a
demonstration that the area will
continue to maintain the NAAQS
throughout the duration of the requisite
maintenance period. Consistent with the
prior guidance documents discussed
previously in this document as well as
EPA’s November 20, 2018 ‘‘Resource
Document for 1997 Ozone NAAQS
Areas: Supporting Information for States
Developing Maintenance Plans’’ (2018
Resource Document),11 EPA believes
that if the most recent DV for the area
is well below the NAAQS (e.g. below
85%, or in this case below 0.071 ppm),
the section 175A demonstration
requirement has been met, provided that
Prevention of Significant Deterioration
(PSD) requirements, any control
measures already in the SIP, and any
Federal measures remain in place
through the end of the second 10-year
maintenance period (absent a showing
consistent with section 110(l) that such
measures are not necessary to assure
maintenance).
For the purposes of demonstrating
continued maintenance with the 1997
ozone NAAQS, DEP provided 3-year
DVs at monitors located in the
Harrisburg-Lebanon-Carlisle Area from
2009 to 2019. This includes DVs at
monitors for 2009–2011, 2010–2012,
2011–2013, 2012–2014, 2013–2015,
2014–2016, 2015–2017, and 2016–2018,
which are shown in Table 2.12 In

notice proposing to redesignate the HarrisburgLebanon-Carlisle Area to attainment for the 1997
ozone NAAQS (72 FR 40749).

addition, EPA has reviewed the most
recent ambient air quality monitoring
data for ozone in the HarrisburgLebanon-Carlisle Area, as submitted by
Pennsylvania and recorded in EPA’s Air
Quality System (AQS). The most recent
DV (i.e. 2017–2019) at monitors located
in the Harrisburg-Lebanon-Carlisle Area
are also shown in Table 2.13 There are
three monitoring sites in the HarrisburgLebanon-Carlisle area, two in Dauphin
County and one in Lebanon County.
Please note that there was a monitor in
Perry County (monitor 42–099–0301),
but it was discontinued on October 31,
2014. As can be seen in Table 2, DVs at
all monitors located in the HarrisburgLebanon-Carlisle Area have been well
below 85% of the 1997 ozone NAAQS
(i.e. 0.071 ppm) since the 2014–2016
period. The highest DV for the 2017–
2019 period at a monitor in the
Harrisburg-Lebanon-Carlisle Area is
0.066 ppm, which is well below 85% of
the 1997 NAAQS.

* Monitor 42–043–0401 was shut down in January 2012 and moved to a new site.
Additionally, states can support the
demonstration of continued
maintenance by showing stable or
improving air quality trends. According
to EPA’s 2018 Resource Document,
several kinds of analyses can be
performed by states wishing to make
such a showing. One approach is to take
the highest, most recent DV at a monitor
located in the area and add the
maximum design value increase (over
one or more consecutive years) that has
been observed in the area over the past
several years. A sum that does not
exceed the level of the 1997 ozone
NAAQS may be a good indicator of
expected continued attainment. As
shown in Table 2, the largest increase in
DVs at a monitor located in the
Harrisburg-Lebanon-Carlisle Area was
0.004 ppm, which occurred between the
2009–2011 (0.073 ppm) and the 2010–
2012 (0.077 ppm) DVs at the monitor
located in Dauphin County (AQS ID 42–
043–1100). Adding 4 ppb to the highest
DV for the 2017–2019 period (0.066
ppm) results in 0.070 ppm, a sum that
is still below the 1997 ozone NAAQS.
The Harrisburg-Lebanon-Carlisle Area
has maintained air quality levels well
below the 1997 ozone NAAQS since the
Area first attained the NAAQS in
2005.14 Additional supporting
information that the area is expected to
continue to maintain the standard can
be found in projections of future year
DVs that EPA recently completed to
assist states with development of
interstate transport SIPs for the 2015 8hour ozone NAAQS. Those projections,
made for the year 2023, show that the
highest DV at a monitor located in the
Harrisburg-Lebanon-Carlisle Area is
expected to be 0.0586 ppm.15 Therefore,
EPA proposes to determine that future
violations of the 1997 ozone NAAQS in
the Harrisburg-Lebanon-Carlisle Area
are unlikely.
13 This data is also included in the docket for this
rulemaking available online at https://

14 As explained in EPA’s July 25, 2007 notice
proposing to redesignate the Harrisburg-LebanonCarlisle County Area as attainment for the 1997
ozone NAAQS (72 FR 40749), the 2003–2005 DV for
the Harrisburg-Lebanon-Carlisle Area was 0.075
ppm.

C. Continued Air Quality Monitoring
and Verification of Continued
Attainment
Once an area has been redesignated to
attainment, the state remains obligated
to maintain an air quality network in
accordance with 40 CFR part 58, in
order to verify the area’s attainment
status. In the February 27, 2020
submittal, DEP commits to continue to
operate their air monitoring network in
accordance with 40 CFR part 58. DEP
also commits to track the attainment
status of the Harrisburg-LebanonCarlisle Area for the 1997 ozone
NAAQS through the review of air
quality and emissions data during the
second maintenance period. This
includes an annual evaluation of
vehicles miles traveled (VMT) and
stationary source emissions data
compared to the assumptions included
in the LMP. DEP also states that it will
also evaluate the periodic (i.e., every
three years) emission inventories
prepared under EPA’s Air Emission
Reporting Requirements (40 CFR part
51, subpart A). Based on these
evaluations, DEP will consider whether
any further emission control measures
should be implemented for the
Harrisburg-Lebanon-Carlisle County
Area. EPA has analyzed the
commitments in DEP’s submittal and is
proposing to determine that they meet
PO 00000
Frm 00013
Fmt 4702
Sfmt 4702
the requirements for continued air
quality monitoring and verification of
continued attainment.
D. Contingency Plan
The contingency plan provisions are
designed to promptly correct or prevent
a violation of the NAAQS that might
occur after redesignation of an area to
attainment. Section 175A of the CAA
requires that a maintenance plan
include such contingency measures as
EPA deems necessary to assure that the
state will promptly correct a violation of
the NAAQS that occurs after
redesignation. The maintenance plan
should identify the contingency
measures to be adopted, a schedule and
procedure for adoption and
implementation of the contingency
measures, and a time limit for action by
the state. The state should also identify
specific indicators to be used to
determine when the contingency
measures need to be adopted and
implemented. The maintenance plan
must require that the state will
implement all pollution control
measures that were contained in the SIP
before redesignation of the area to
attainment. See section 175(A)(d) of the
CAA.
DEP’s February 27, 2020 submittal
includes a contingency plan for the
Harrisburg-Lebanon-Carlisle Area. In the
event that the fourth highest eight-hour
ozone concentrations at a monitor in the
Harrisburg-Lebanon-Carlisle Area
exceeds 84 ppb (equivalent to 0.084
ppm) for two consecutive years, but
prior to an actual violation of the
NAAQS, DEP will evaluate whether

additional local emission control
measures should be implemented that
may prevent a violation of the
NAAQS.16 After analyzing the
conditions causing the excessive ozone
levels, evaluating the effectiveness of
potential corrective measures, and
considering the potential effects of
federal, state, and local measures that
have been adopted but not yet
implemented, DEP will begin the
process of implementing selected
measures so that they can be
implemented as expeditiously as
practicable following a violation of the
NAAQS. In the event of a violation, DEP
commits to adopting additional
emission reduction measures as
expeditiously as practicable in
accordance with the schedule included
in the contingency plan as well as the
CAA and applicable Pennsylvania
statutory requirements.
DEP will use the following criteria
when considering additional emission
reduction measures to adopt to address
a violation of the 1997 ozone NAAQS in
the Harrisburg-Lebanon-Carlisle Area:
(1) Air quality analysis indicating the
nature of the violation, including the
cause, location, and source; (2) emission
reduction potential, including extent to
which emission generating sources
occur in the nonattainment area; (3)
timeliness of implementation in terms
of the potential to return the area to
attainment as expeditiously as
practicable; and (4) costs, equity, and
cost-effectiveness. The measures DEP
would consider pursuing for adoption
in the Harrisburg-Lebanon-Carlisle Area
include, but are not limited to, those
summarized in Table 3. If additional
emission reductions are necessary, DEP
commits to adopt additional emission
reduction measures to attain and
maintain the 1997 ozone NAAQS.

EPA proposes to find that the
contingency plan included in DEP’s
February 27, 2020 submittal satisfies the
pertinent requirements of CAA section
175A(d). EPA notes that while six of the
potential contingency measures
included in the Commonwealth’s
second maintenance plan are nonregulatory, their inclusion among other
measures is overall SIP-strengthening,
and their inclusion does not alter EPA’s
proposal to find the LMP is fully
approvable. EPA also finds that the
submittal acknowledges Pennsylvania’s
continuing requirement to implement
all pollution control measures that were
contained in the SIP before
redesignation of the HarrisburgLebanon-Carlisle Area to attainment.
E. Transportation Conformity
Transportation conformity is required
by section 176(c) of the CAA.
Conformity to a SIP means that
transportation activities will not
produce new air quality violations,
worsen existing violations, or delay
timely attainment of the NAAQS (CAA
176(c)(1)(B)). EPA’s conformity rule at
40 CFR part 93 requires that
transportation plans, programs and
projects conform to SIPs and establish
the criteria and procedures for
determining whether or not they
conform. The conformity rule generally
requires a demonstration that emissions
from the Regional Transportation Plan
(RTP) and the Transportation
Improvement Program (TIP) are
consistent with the motor vehicle
emissions budget (MVEB) contained in
the control strategy SIP revision or
maintenance plan (40 CFR 93.101,
93.118, and 93.124). A MVEB is defined
as ‘‘that portion of the total allowable
emissions defined in the submitted or
approved control strategy
VerDate Sep<11>2014
16:16 Sep 02, 2020
Jkt 250001
implementation plan revision or
maintenance plan for a certain date for
the purpose of meeting reasonable
further progress milestones or
demonstrating attainment or
maintenance of the NAAQS, for any
criteria pollutant or its precursors,
allocated to highway and transit vehicle
use and emissions (40 CFR 93.101).
Under the conformity rule, LMP areas
may demonstrate conformity without a
regional emission analysis (40 CFR
93.109(e)). However, because LMP areas
are still maintenance areas, certain
aspects of transportation conformity
determinations still will be required for
transportation plans, programs and
projects. Specifically, for such
determination, RTPs, TIPs and
transportation projects still will have to
demonstrate that they are fiscally
constrained (40 CFR 93.108), meet the
criteria for consultation (40 CFR 93.105
and 93.112) and transportation control
measure implementation in the
conformity rule provisions (40 CFR
93.113). Additionally, conformity
determinations for RTPs and TIPs must
be determined no less frequently than
every four years, and conformity of
transportation plan and TIP
amendments and transportation projects
is demonstrated in accordance with the
timing requirements specified in 40 CFR
93.104. In addition, for projects to be
approved, they must come from a
currently conforming RTP and TIP (40
CFR 93.114 and 93.115). The
Harrisburg-Lebanon-Carlisle Area
remains under the obligation to meet the
applicable conformity requirements for
the 1997 ozone NAAQS.
III. Proposed Action
EPA’s review of DEP’s February 27,
2020 submittal indicates that
Harrisburg-Lebanon-Carlisle Area
PO 00000
Frm 00015
Fmt 4702
Sfmt 4702
second maintenance plan meets the
CAA section 175A and all applicable
CAA requirements. EPA is proposing to
approve the second maintenance plan
for the Harrisburg-Lebanon-Carlisle area
as a revision to the Pennsylvania SIP.
EPA is soliciting public comments on
the issues discussed in this document.
These comments will be considered
before taking final action.
IV. Statutory and Executive Order
Reviews
Under the CAA, the Administrator is
required to approve a SIP submission
that complies with the provisions of the
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 approves 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);
• Is not an Executive Order 13771 (82
FR 9339, February 2, 2017) regulatory
action because SIP approvals are
exempted under Executive Order 12866.
• 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.);
E:\FR\FM\03SEP1.SGM
03SEP1
54960
Federal Register / Vol. 85, No. 172 / Thursday, September 3, 2020 / Proposed Rules
• 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, proposing approval of
pertaining Pennsylvania’s second
limited maintenance plan for
Harrisburg-Lebanon-Carlisle area, does
not have tribal implications as specified
by Executive Order 13175 (65 FR 67249,
November 9, 2000), because the SIP is
not approved to apply in Indian country
located in the State, and EPA notes that
it will not impose substantial direct
costs on tribal governments or preempt
tribal law.

supplementary information section is
arranged as follows:
I. What action is the EPA taking?
On May 26, 2020, at 85 FR 31421, the
EPA proposed to approve the
Washington State Implementation Plan
(SIP) as meeting certain infrastructure
requirements for the 2010 SO2 and 2015
ozone NAAQS, specifically CAA section
110(a)(2)(A), (B), (C) (except for those
provisions covered by the PSD FIP),
(D)(i)(II) (except for those provisions
covered by the PSD and regional haze
FIPs), (D)(ii) (except for those provisions
covered by the PSD FIP), (E), (F), (G),
(H), (J) (except for those provisions
covered by the PSD FIP), (K), (L), and
(M). We received three comments on the
original proposal. Two of the comments
noted that the EPA neglected to include
the technical support document (TSD)
in the docket explaining the EPA’s
rationale for the proposed approval. Due
to this administrative error, the EPA is
providing an additional 30 days for
public comment on the proposed action.
A third comment suggested that
insufficient information was provided
in the docket to allow the reviewer to
fully evaluate the EPA’s rationale in
proposing to approve the Washington
SIP as meeting the requirements of CAA
section 110(a)(2)(E) regarding
assurances of adequate resources.
Section 110(a)(2)(E) requires states to
provide for adequate personnel,
funding, and legal authority under state
law to carry out its SIP, that the state
comply with the requirements of CAA
section 128 respecting state boards and
conflict of interest, and necessary
assurances that, where the state has
relied on a local or regional government,
agency, or instrumentality for the
implementation of any plan provision,
the state has responsibility for ensuring
adequate implementation of such plan
provision.

SUPPLEMENTARY INFORMATION: On February 27, 2020, DEP submitted a
revision to the Pennsylvania SIP to incorporate a plan for maintaining
the 1997 ozone NAAQS through July 25, 2027 in accordance with CAA
section 175A. The submittal is titled, ``State Implementation Plan
Revision: Second Maintenance Plan for the Harrisburg-Lebanon-Carlisle
1997 8-Hour Ozone Nonattainment Area,'' which will be referred to as
the ``Harrisburg-Lebanon-Carlisle Area second maintenance plan''
throughout this document.
I. Background
In 1979, under section 109 of the CAA, EPA established primary and
secondary NAAQS for ozone at 0.12 parts per million (ppm), averaged
over
[[Page 54955]]
a 1-hour period. 44 FR 8202 (February 8, 1979). On July 18, 1997 (62 FR
38856).\1\ EPA revised the primary and secondary NAAQS for ozone to set
the acceptable level of ozone in the ambient air at 0.08 ppm, averaged
over an 8-hour period. EPA set the 1997 ozone NAAQS based on scientific
evidence demonstrating that ozone causes adverse health effects at
lower concentrations and over longer periods of time than was
understood when the pre-existing 1-hour ozone NAAQS was set.
---------------------------------------------------------------------------
\1\ In March 2008, EPA completed another review of the primary
and secondary ozone standards and tightened them further by lowering
the level for both to 0.075 ppm. 73 FR 16436 (March 27, 2008).
Additionally, in October 2015, EPA completed a review of the primary
and secondary ozone standards and tightened them by lowering the
level for both to 0.70 ppm. 80 FR 65292 (October 26, 2015).
---------------------------------------------------------------------------
Following promulgation of a new or revised NAAQS, EPA is required
by the CAA to designate areas throughout the nation as attaining or not
attaining the NAAQS. On June 15, 2004 (69 FR 23858), EPA designated the
Harrisburg-Lebanon-Carlisle Area as a nonattainment area for the 1997
ozone NAAQS. The area, consisting of Cumberland, Dauphin, Lebanon and
Perry Counties, was redesignated to attainment on July 25, 2007 (72 FR
40749), and effective the same day.
Once a nonattainment area has three years of complete and certified
air quality data that has been determined to attain the NAAQS, and the
area has met the other criteria outlined in CAA section
107(d)(3)(E),\2\ the state can submit a request to EPA to redesignate
the area to attainment. Areas that have been redesignated by EPA from
nonattainment to attainment are referred to as ``maintenance areas.''
One of the criteria for redesignation is to have an approved
maintenance plan, under CAA section 175A. The maintenance plan must
demonstrate that the area will continue to maintain the standard for
the period extending 10 years after redesignation, and it must contain
such additional measures as necessary to ensure maintenance as well as
contingency measures as necessary to assure that violations of the
standard will be promptly corrected.
---------------------------------------------------------------------------
\2\ The requirements of CAA section 107(d)(3)(E) include
attainment of the NAAQS, full approval under section 110(k) of the
applicable SIP, determination that improvement in air quality is a
result of permanent and enforceable reductions in emissions,
demonstration that the state has met all applicable section 110 and
part D requirements, and a fully approved maintenance plan under CAA
section 175A.
---------------------------------------------------------------------------
On July 25, 2007 (72 FR 40749 effective July 25, 2007), EPA
approved a redesignation request (and maintenance plan) from DEP for
the Harrisburg-Lebanon-Carlisle area. In accordance with section
175A(b), at the end of the eighth year after the effective date of the
redesignation, the state must also submit a second maintenance plan to
ensure ongoing maintenance of the standard for an additional 10 years.
EPA's final implementation rule for the 2008 ozone NAAQS revoked
the 1997 ozone NAAQS and provided that one consequence of revocation
was that areas that had been redesignated to attainment (i.e.,
maintenance areas) for the 1997 ozone NAAQS no longer needed to submit
second 10-year maintenance plans under CAA section 175A(b).\3\ However,
in South Coast Air Quality Management District v. EPA \4\ (South Coast
II), the United States Court of Appeals for the District of Columbia
(D.C. Circuit) vacated EPA's interpretation that, because of the
revocation of the 1997 ozone standard, second maintenance plans were
not required for ``orphan maintenance areas,'' (i.e. the Harrisburg-
Lebanon-Carlisle area) that had been redesignated to attainment for the
1997 ozone NAAQS and were designated attainment for the 2008 ozone
NAAQS. Thus, states with these ``orphan maintenance areas'' under the
1997 ozone NAAQS must submit maintenance plans for the second
maintenance period.
---------------------------------------------------------------------------
\3\ See 80 FR 12315 (March 6, 2015).
\4\ 882 F.3d 1138 (D.C. Cir. 2018).
---------------------------------------------------------------------------
As previously discussed, CAA section 175A sets forth the criteria
for adequate maintenance plans. In addition, EPA has published
longstanding guidance that provides further insight on the content of
an approvable maintenance plan, explaining that a maintenance plan
should address five elements: (1) An attainment emissions inventory;
(2) a maintenance demonstration; (3) a commitment for continued air
quality monitoring; (4) a process for verification of continued
attainment; and (5) a contingency plan. The 1992 Calcagni Memo \5\
provides that states may generally demonstrate maintenance by either
performing air quality modeling to show that the future mix of sources
and emission rates will not cause a violation of the NAAQS or by
showing that future emissions of a pollutant and its precursors will
not exceed the level of emissions during a year when the area was
attaining the NAAQS (i.e., attainment year inventory). See 1992
Calcagni Memo at p. 9. EPA further clarified in three subsequent
guidance memos describing ``limited maintenance plans'' (LMPs) \6\ that
the requirements of CAA section 175A could be met by demonstrating that
the area's design value \7\ was well below the NAAQS and that the
historical stability of the area's air quality levels showed that the
area was unlikely to violate the NAAQS in the future. Specifically, EPA
believes that if the most recent air quality design value for the area
is at a level that is below 85% of the standard, or in this case below
0.071 ppm, then EPA considers the state to have met the section 175A
requirement for a demonstration that the area will maintain the NAAQS
for the requisite period. Accordingly, on February 27, 2020, DEP
submitted the Harrisburg-Lebanon-Carlisle Area second maintenance plan,
following the LMP guidance, and demonstrating that the area will
maintain the 1997 ozone NAAQS through July 25, 2027, i.e., through the
entire 20-year maintenance period.
---------------------------------------------------------------------------
\5\ ``Procedures for Processing Requests to Redesignate Areas to
Attainment,'' Memorandum from John Calcagni, Director, Air Quality
Management Division, September 4, 1992 (1992 Calcagni Memo).

Ozone Nonattainment Areas'' from Sally L. Shaver, Office of Air
Quality Planning and Standards (OAQPS), dated November 16, 1994;

\7\ The ozone design value for a monitoring site is the 3-year
average of the annual fourth-highest daily maximum 8-hour average
ozone concentrations. The design value for an ozone nonattainment
area is the highest design value of any monitoring site in the area.
---------------------------------------------------------------------------
II. Summary of SIP Revision and EPA Analysis
DEP's February 27, 2020 SIP submittal outlines a plan for continued
maintenance of the 1997 ozone NAAQS which addresses the criteria set
forth in the 1992 Calcagni Memo as follows.
A. Attainment Emissions Inventory
For maintenance plans, a state should develop a comprehensive and
accurate inventory of actual emissions for an attainment year which
identifies the level of emissions in the area which is sufficient to
maintain the NAAQS. The inventory should be developed consistent with
EPA's most recent guidance. For ozone, the inventory should be based on
typical summer day's emissions of oxides of nitrogen (NOX)
and volatile organic compounds (VOC), the precursors to ozone
formation. In the first maintenance plan for the Harrisburg-Lebanon-
Carlisle Area, DEP used 2004 for the attainment year inventory, because
2004 was one of the years in the 2003-2005 three-year period when the
area first attained the
[[Page 54956]]
1997 ozone NAAQS.\8\ The Harrisburg-Lebanon-Carlisle Area continued to
monitor attainment of the 1997 ozone NAAQS in 2014. Therefore, the
emissions inventory from 2014 represents emissions levels conducive to
continued attainment (i.e., maintenance) of the NAAQS. Thus, DEP is
using 2014 as representing attainment level emissions for its second
maintenance plan. Pennsylvania used 2014 summer day emissions from
EPA's 2014 version 7.0 modeling platform as the basis for the 2014
inventory presented in Table 1.\9\
---------------------------------------------------------------------------

proposing to redesignate the Harrisburg-Lebanon-Carlisle Area to
attainment for the 1997 ozone NAAQS (72 FR 40749).

Nonroad......................... 1.33 0.57
-------------------------------
Total..................................... ................................ 58.04 81.03
----------------------------------------------------------------------------------------------------------------
The data shown in Table 1 is based on the 2014 National Emissions
Inventory (NEI) version 2.\10\ The inventory addresses four
anthropogenic emission source categories: Stationary (point) sources,
stationary nonpoint (area) sources, nonroad mobile, and onroad mobile
sources. Point sources are stationary sources that have the potential
to emit (PTE) more than 100 tons per year (tpy) of VOC, or more than 50
tpy of NOX, and which are required to obtain an operating
permit. Data are collected for each source at a facility and reported
to DEP. Examples of point sources include kraft mills, electrical
generating units (EGUs), and pharmaceutical factories. Nonpoint sources
include emissions from equipment, operations, and activities that are
numerous and in total have significant emissions. Examples include
emissions from commercial and consumer products, portable fuel
containers, home heating, repair and refinishing operations, and
crematories. The onroad emissions sector includes emissions from
engines used primarily to propel equipment on highways and other roads,
including passenger vehicles, motorcycles, and heavy-duty diesel
trucks. The nonroad emissions sector includes emissions from engines
that are not primarily used to propel transportation equipment, such as
generators, forklifts, and marine pleasure craft.
---------------------------------------------------------------------------
\10\ The NEI is a comprehensive and detailed estimate of air
emissions of criteria pollutants, criteria precursors, and hazardous
air pollutants from air emissions sources. The NEI is released every
three years based primarily upon data provided by State, Local, and
Tribal air agencies for sources in their jurisdictions and
supplemented by data developed by EPA.
---------------------------------------------------------------------------
EPA reviewed the emissions inventory submitted by DEP and proposes
to conclude that the plan's inventory is acceptable for the purposes of
a subsequent maintenance plan under CAA section 175A(b).
B. Maintenance Demonstration
In order to attain the 1997 ozone NAAQS, the three-year average of
the fourth-highest daily average ozone concentrations (design value, or
``DV'') at each monitor within an area must not exceed 0.08 ppm. Based
on the rounding convention described in 40 CFR part 50, appendix I, the
standard is attained if the DV is 0.084 ppm or below. CAA section 175A
requires a demonstration that the area will continue to maintain the
NAAQS throughout the duration of the requisite maintenance period.
Consistent with the prior guidance documents discussed previously in
this document as well as EPA's November 20, 2018 ``Resource Document
for 1997 Ozone NAAQS Areas: Supporting Information for States
Developing Maintenance Plans'' (2018 Resource Document),\11\ EPA
believes that if the most recent DV for the area is well below the
NAAQS (e.g. below 85%, or in this case below 0.071 ppm), the section
175A demonstration requirement has been met, provided that Prevention
of Significant Deterioration (PSD) requirements, any control measures
already in the SIP, and any Federal measures remain in place through
the end of the second 10-year maintenance period (absent a showing
consistent with section 110(l) that such measures are not necessary to
assure maintenance).
---------------------------------------------------------------------------
\11\ This resource document is included in the docket for this
rulemaking available online at https://www.regulations.gov, Docket
ID: EPA-R03-OAR-2020-0288 and is also available at https://www.epa.gov/sites/production/files/2018-11/documents/ozone_1997_naaqs_lmp_resource_document_nov_20_2018.pdf.
---------------------------------------------------------------------------
For the purposes of demonstrating continued maintenance with the
1997 ozone NAAQS, DEP provided 3-year DVs at monitors located in the
Harrisburg-Lebanon-Carlisle Area from 2009 to 2019. This includes DVs
at monitors for 2009-2011, 2010-2012, 2011-2013, 2012-2014, 2013-2015,
2014-2016, 2015-2017, and 2016-2018, which are shown in Table 2.\12\ In
[[Page 54957]]
addition, EPA has reviewed the most recent ambient air quality
monitoring data for ozone in the Harrisburg-Lebanon-Carlisle Area, as
submitted by Pennsylvania and recorded in EPA's Air Quality System
(AQS). The most recent DV (i.e. 2017-2019) at monitors located in the
Harrisburg-Lebanon-Carlisle Area are also shown in Table 2.\13\ There
are three monitoring sites in the Harrisburg-Lebanon-Carlisle area, two
in Dauphin County and one in Lebanon County. Please note that there was
a monitor in Perry County (monitor 42-099-0301), but it was
discontinued on October 31, 2014. As can be seen in Table 2, DVs at all
monitors located in the Harrisburg-Lebanon-Carlisle Area have been well
below 85% of the 1997 ozone NAAQS (i.e. 0.071 ppm) since the 2014-2016
period. The highest DV for the 2017-2019 period at a monitor in the
Harrisburg-Lebanon-Carlisle Area is 0.066 ppm, which is well below 85%
of the 1997 NAAQS.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
* Monitor 42-043-0401 was shut down in January 2012 and moved to a new site.
Additionally, states can support the demonstration of continued
maintenance by showing stable or improving air quality trends.
According to EPA's 2018 Resource Document, several kinds of analyses
can be performed by states wishing to make such a showing. One approach
is to take the highest, most recent DV at a monitor located in the area
and add the maximum design value increase (over one or more consecutive
years) that has been observed in the area over the past several years.
A sum that does not exceed the level of the 1997 ozone NAAQS may be a
good indicator of expected continued attainment. As shown in Table 2,
the largest increase in DVs at a monitor located in the Harrisburg-
Lebanon-Carlisle Area was 0.004 ppm, which occurred between the 2009-
2011 (0.073 ppm) and the 2010-2012 (0.077 ppm) DVs at the monitor
located in Dauphin County (AQS ID 42-043-1100). Adding 4 ppb to the
highest DV for the 2017-2019 period (0.066 ppm) results in 0.070 ppm, a
sum that is still below the 1997 ozone NAAQS.
The Harrisburg-Lebanon-Carlisle Area has maintained air quality
levels well below the 1997 ozone NAAQS since the Area first attained
the NAAQS in 2005.\14\ Additional supporting information that the area
is expected to continue to maintain the standard can be found in
projections of future year DVs that EPA recently completed to assist
states with development of interstate transport SIPs for the 2015 8-
hour ozone NAAQS. Those projections, made for the year 2023, show that
the highest DV at a monitor located in the Harrisburg-Lebanon-Carlisle
Area is expected to be 0.0586 ppm.\15\ Therefore, EPA proposes to
determine that future violations of the 1997 ozone NAAQS in the
Harrisburg-Lebanon-Carlisle Area are unlikely.
---------------------------------------------------------------------------
\14\ As explained in EPA's July 25, 2007 notice proposing to
redesignate the Harrisburg-Lebanon-Carlisle County Area as
attainment for the 1997 ozone NAAQS (72 FR 40749), the 2003-2005 DV
for the Harrisburg-Lebanon-Carlisle Area was 0.075 ppm.
\15\ See U.S. EPA, ``Air Quality Modeling Technical Support
Document for the Updated 2023 Projected Ozone Design Values'',
Office of Air Quality Planning and Standards, dated June 2018,
available at https://www.epa.gov/airmarkets/air-quality-modeling-technical-support-document-updated-2023-projected-ozone-design.
---------------------------------------------------------------------------
C. Continued Air Quality Monitoring and Verification of Continued
Attainment
Once an area has been redesignated to attainment, the state remains
obligated to maintain an air quality network in accordance with 40 CFR
part 58, in order to verify the area's attainment status. In the
February 27, 2020 submittal, DEP commits to continue to operate their
air monitoring network in accordance with 40 CFR part 58. DEP also
commits to track the attainment status of the Harrisburg-Lebanon-
Carlisle Area for the 1997 ozone NAAQS through the review of air
quality and emissions data during the second maintenance period. This
includes an annual evaluation of vehicles miles traveled (VMT) and
stationary source emissions data compared to the assumptions included
in the LMP. DEP also states that it will also evaluate the periodic
(i.e., every three years) emission inventories prepared under EPA's Air
Emission Reporting Requirements (40 CFR part 51, subpart A). Based on
these evaluations, DEP will consider whether any further emission
control measures should be implemented for the Harrisburg-Lebanon-
Carlisle County Area. EPA has analyzed the commitments in DEP's
submittal and is proposing to determine that they meet the requirements
for continued air quality monitoring and verification of continued
attainment.
D. Contingency Plan
The contingency plan provisions are designed to promptly correct or
prevent a violation of the NAAQS that might occur after redesignation
of an area to attainment. Section 175A of the CAA requires that a
maintenance plan include such contingency measures as EPA deems
necessary to assure that the state will promptly correct a violation of
the NAAQS that occurs after redesignation. The maintenance plan should
identify the contingency measures to be adopted, a schedule and
procedure for adoption and implementation of the contingency measures,
and a time limit for action by the state. The state should also
identify specific indicators to be used to determine when the
contingency measures need to be adopted and implemented. The
maintenance plan must require that the state will implement all
pollution control measures that were contained in the SIP before
redesignation of the area to attainment. See section 175(A)(d) of the
CAA.
DEP's February 27, 2020 submittal includes a contingency plan for
the Harrisburg-Lebanon-Carlisle Area. In the event that the fourth
highest eight-hour ozone concentrations at a monitor in the Harrisburg-
Lebanon-Carlisle Area exceeds 84 ppb (equivalent to 0.084 ppm) for two
consecutive years, but prior to an actual violation of the NAAQS, DEP
will evaluate whether
[[Page 54958]]
additional local emission control measures should be implemented that
may prevent a violation of the NAAQS.\16\ After analyzing the
conditions causing the excessive ozone levels, evaluating the
effectiveness of potential corrective measures, and considering the
potential effects of federal, state, and local measures that have been
adopted but not yet implemented, DEP will begin the process of
implementing selected measures so that they can be implemented as
expeditiously as practicable following a violation of the NAAQS. In the
event of a violation, DEP commits to adopting additional emission
reduction measures as expeditiously as practicable in accordance with
the schedule included in the contingency plan as well as the CAA and
applicable Pennsylvania statutory requirements.
---------------------------------------------------------------------------
\16\ A violation of the NAAQS occurs when an area's 3-year
design value exceeds the NAAQS.
---------------------------------------------------------------------------
DEP will use the following criteria when considering additional
emission reduction measures to adopt to address a violation of the 1997
ozone NAAQS in the Harrisburg-Lebanon-Carlisle Area: (1) Air quality
analysis indicating the nature of the violation, including the cause,
location, and source; (2) emission reduction potential, including
extent to which emission generating sources occur in the nonattainment
area; (3) timeliness of implementation in terms of the potential to
return the area to attainment as expeditiously as practicable; and (4)
costs, equity, and cost-effectiveness. The measures DEP would consider
pursuing for adoption in the Harrisburg-Lebanon-Carlisle Area include,
but are not limited to, those summarized in Table 3. If additional
emission reductions are necessary, DEP commits to adopt additional
emission reduction measures to attain and maintain the 1997 ozone
NAAQS.

------------------------------------------------------------------------
EPA proposes to find that the contingency plan included in DEP's
February 27, 2020 submittal satisfies the pertinent requirements of CAA
section 175A(d). EPA notes that while six of the potential contingency
measures included in the Commonwealth's second maintenance plan are
non-regulatory, their inclusion among other measures is overall SIP-
strengthening, and their inclusion does not alter EPA's proposal to
find the LMP is fully approvable. EPA also finds that the submittal
acknowledges Pennsylvania's continuing requirement to implement all
pollution control measures that were contained in the SIP before
redesignation of the Harrisburg-Lebanon-Carlisle Area to attainment.
E. Transportation Conformity
Transportation conformity is required by section 176(c) of the CAA.
Conformity to a SIP means that transportation activities will not
produce new air quality violations, worsen existing violations, or
delay timely attainment of the NAAQS (CAA 176(c)(1)(B)). EPA's
conformity rule at 40 CFR part 93 requires that transportation plans,
programs and projects conform to SIPs and establish the criteria and
procedures for determining whether or not they conform. The conformity
rule generally requires a demonstration that emissions from the
Regional Transportation Plan (RTP) and the Transportation Improvement
Program (TIP) are consistent with the motor vehicle emissions budget
(MVEB) contained in the control strategy SIP revision or maintenance
plan (40 CFR 93.101, 93.118, and 93.124). A MVEB is defined as ``that
portion of the total allowable emissions defined in the submitted or
approved control strategy implementation plan revision or maintenance
plan for a certain date for the purpose of meeting reasonable further
progress milestones or demonstrating attainment or maintenance of the
NAAQS, for any criteria pollutant or its precursors, allocated to
highway and transit vehicle use and emissions (40 CFR 93.101).
Under the conformity rule, LMP areas may demonstrate conformity
without a regional emission analysis (40 CFR 93.109(e)). However,
because LMP areas are still maintenance areas, certain aspects of
transportation conformity determinations still will be required for
transportation plans, programs and projects. Specifically, for such
determination, RTPs, TIPs and transportation projects still will have
to demonstrate that they are fiscally constrained (40 CFR 93.108), meet
the criteria for consultation (40 CFR 93.105 and 93.112) and
transportation control measure implementation in the conformity rule
provisions (40 CFR 93.113). Additionally, conformity determinations for
RTPs and TIPs must be determined no less frequently than every four
years, and conformity of transportation plan and TIP amendments and
transportation projects is demonstrated in accordance with the timing
requirements specified in 40 CFR 93.104. In addition, for projects to
be approved, they must come from a currently conforming RTP and TIP (40
CFR 93.114 and 93.115). The Harrisburg-Lebanon-Carlisle Area remains
under the obligation to meet the applicable conformity requirements for
the 1997 ozone NAAQS.
III. Proposed Action
EPA's review of DEP's February 27, 2020 submittal indicates that
Harrisburg-Lebanon-Carlisle Area second maintenance plan meets the CAA
section 175A and all applicable CAA requirements. EPA is proposing to
approve the second maintenance plan for the Harrisburg-Lebanon-Carlisle
area as a revision to the Pennsylvania SIP. EPA is soliciting public
comments on the issues discussed in this document. These comments will
be considered before taking final action.
IV. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the 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 approves 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);
Is not an Executive Order 13771 (82 FR 9339, February 2,
2017) regulatory action because SIP approvals are exempted under
Executive Order 12866.
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.);
[[Page 54960]]
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, proposing approval of
pertaining Pennsylvania's second limited maintenance plan for
Harrisburg-Lebanon-Carlisle area, does not have tribal implications as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000),
because the SIP is not approved to apply in Indian country located in
the State, and EPA notes that it will not impose substantial direct
costs on tribal governments or preempt tribal law.
