SUMMARY:
VerDate Sep<11>2014

Jkt 265001
(NPRM) for the State of Delaware. In the
NPRM, EPA proposed approval of a
revision to the Delaware SIP that
consists of amendments to Title 7 of the
Delaware Administrative Code (7 DE
Admin). Specifically, the amendments
are to 7 DE Admin 1103 Ambient Air
Quality Standards (DE 1103). DNREC’s
amendments to DE 1103 aligned the
language of that regulation to be
consistent with existing Federal
regulatory standards. Specifically,
DNREC revised DE 1103 to reflect: the
most current national ambient air
quality standards (NAAQS) for ground
level ozone; amendments to update
citations in DE 1103 to include the CFR
dates in effect at the time DNREC
amended DE 1103 for all NAAQS; and
amendments to remove the SO2 24-hour
and annual primary standards. On May
14, 2024, DNREC submitted a
withdrawal letter to remove an update
to section 1.6.5 of DE 1103 in
Delaware’s SIP. Delaware withdrew its
revision to section 1.6.5 because that
regulation erroneously cites an EPA
analytical method that was revoked by
EPA. The formal SIP revision was
submitted by Delaware on November 15,
2022. By a letter dated May 14, 2023,
Delaware withdrew a portion of the
submission that referenced an obsolete
EPA monitoring methodology.
I. Background
The CAA mandates that the EPA set
NAAQS for criteria pollutants, which
are ozone and related photochemical
oxidants, carbon monoxide, lead,
nitrogen oxides, particulate matter, and
sulfur oxides. The CAA also requires
EPA to periodically review the relevant
scientific information and the standards
and revise them, if appropriate, to
ensure that the standards provide the
requisite protection for public health
and the environment. The CAA also
requires states to develop a general plan
to attain and maintain the standards in
all areas of the country and a specific
plan to attain the standards for each area
designated nonattainment.
The NAAQS for ground-level ozone
were updated on October 1, 2015, to
strengthen the NAAQS for ground-level
ozone to 0.070 parts per million (ppm).
See 80 FR 65291.1 The primary and
secondary standards established in 2015
are determined by the fourth-highest
daily maximum 8-hour concentration,
averaged over three consecutive years.
In December 2020, EPA retained the
1 2015 National Ambient Air Quality Standards
for Ozone available at www.federalregister.gov/
documents/2015/10/26/2015–26594/nationalambient-air-quality-standards-for-ozone.

2015 standards without revision. See 85
FR 87256, December 31, 2020.2
On June 2, 2010, EPA revised the
primary SO2 NAAQS based on its
review of the air quality criteria for
oxides of sulfur and the primary
NAAQS for oxides of sulfur as measured
by SO2.3 See 75 FR 35520. The 1-hour
SO2 standard was set at a level of 0.075
ppm, based on the 3-year average of the
annual 99th percentile of 1-hour daily
maximum concentrations. EPA also
revoked both the existing 24-hour and
annual primary SO2 standards.
II. Summary of SIP Revision and EPA
Analysis
Delaware’s November 15, 2022 SIP
submission consists of: (1) amendments
to its ambient air quality standards in
DE 1103 to reflect the current NAAQS
for ground level ozone; (2) amendments
to its regulatory citations to the CFR
dates for the EPA sampling and
analytical procedures and techniques
for the various NAAQS that Delaware
incorporates into its regulations, and (3)
amendments to remove from DE 1103
the SO2 24-hour and annual primary
standards that have been revoked by
EPA. Delaware’s regulatory amendments
aligned DE 1103 with current EPA’s
NAAQS regulations. By including these
revisions to DE 1103 in the Delaware
SIP, the SIP will also align with EPA’s
current NAAQS regulations.
The Delaware SIP’s current primary
and secondary ozone NAAQS standards
are outdated at 0.075 ppm. DNREC’s
revision to DE 1103 updated the
primary and secondary ozone standards
in section 6.0 of DE 1103 to reflect the
2015 Ozone NAAQS of 0.070 ppm. This
approval action for Delaware’s SIP
submittal will make the SIP consistent
with EPA’s current ozone NAAQS.
DNREC has also amended DE 1103 to
update its references to the dates for
EPA’s sampling and analytical
procedures and techniques for the
various NAAQS, that Delaware
incorporates by reference into DE 1103.
The dates, for all sections except 1.6.5,
are updated to July 1, 2019, which was
the most current version of the CFR as
of the time that DNREC revised DE
1103. This approval action will
incorporate into Delaware’s SIP the
NAAQS monitoring methodologies as
codified in the 2019 CFR, which was the
2 2020 Review of the Ozone National Ambient Air
Quality Standards available at
www.federalregister.gov/documents/2020/12/31/
2020-28871/review-of-the-ozone-national-ambientair-quality-standards.

most recent version of the CFR at the
time Delaware revised DE 1103.
Updating these references will
strengthen the Delaware SIP.
Additionally, Delaware removed
subsections 4.2 and 4.3 from DE 1103.
These subsections had set forth
Delaware’s SO2 24-hour primary
standard and SO2 annual primary
standard, which corresponded to the
EPA’s revoked SO2 24-hour primary
standard and SO2 annual primary
standard. This amendment to DE 1103
conforms the Delaware SO2 ambient air
quality standard with EPA’s current
Federal regulations. This approval
action will align Delaware’s SIP with
EPA’s current SO2 NAAQS, at 40 CFR
50.17. No public comments were
received on the NPRM.
III. Final Action
EPA is approving Delaware’s
submittal of November 15, 2022, as
modified by the letter dated May 14,
2023, as a revision to the Delaware SIP.
IV. Incorporation by Reference
In this document, EPA is finalizing
regulatory text that includes
incorporation by reference. In
accordance with requirements of 1 CFR
51.5, EPA is finalizing the incorporation
by reference of DE regulation 1103, as
effective on July 1, 2019, excluding
updates to section 1.6.5, as discussed in
sections I and II of this preamble. EPA
has made, and will continue to make,
these materials generally available
through www.regulations.gov and at the
EPA Region III Office (please contact the
person identified in the For Further
Information Contact section of this
preamble for more information).
Therefore, these materials have been
approved by EPA for inclusion in the
SIP, have been incorporated by
reference by EPA into that plan, are
fully federally enforceable under
sections 110 and 113 of the CAA as of
the effective date of the final rulemaking
of EPA’s approval, and will be
incorporated by reference in the next
update to the SIP compilation.4

V. Statutory and Executive Order
Reviews
A. General Requirements
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
4 62
FR 27968 (May 22, 1997).
VerDate Sep<11>2014
16:08 Dec 20, 2024
Jkt 265001
merely approves state law as meeting
Federal requirements and does not
impose additional requirements beyond
those imposed by state law. For that
reason, this 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); and
• 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 Clean Air Act.
In addition, the SIP is not approved
to apply on any Indian reservation land
or in any other area where 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).
Executive Order 12898 (Federal
Actions to Address Environmental
Justice in Minority Populations and
Low-Income Populations, 59 FR 7629,
February 16, 1994) directs Federal
agencies to identify and address
‘‘disproportionately high and adverse
human health or environmental effects’’
of their actions on minority populations
and low-income populations to the
greatest extent practicable and
permitted by law. EPA defines
environmental justice (EJ) as ‘‘the fair
treatment and meaningful involvement
of all people regardless of race, color,
national origin, or income with respect
PO 00000
Frm 00066
Fmt 4700
Sfmt 4700
to the development, implementation,
and enforcement of environmental laws,
regulations, and policies.’’ EPA further
defines the term fair treatment to mean
that ‘‘no group of people should bear a
disproportionate burden of
environmental harms and risks,
including those resulting from the
negative environmental consequences of
industrial, governmental, and
commercial operations or programs and
policies.’’
DNREC did not evaluate
environmental justice considerations as
part of its SIP submittal; the CAA and
applicable implementing regulations
neither prohibit nor require such an
evaluation. EPA did not perform an E.J.
analysis and did not consider E.J. in this
proposed rulemaking. Due to the nature
of the proposed action being taken here,
this proposed rulemaking is expected to
have a neutral to positive impact on the
air quality of the affected area.
Consideration of EJ is not required as
part of this action, and there is no
information in the record inconsistent
with the stated goal of E.O. 12898 of
achieving environmental justice for
people of color, low-income
populations, and Indigenous peoples.
B. Submission to Congress and the
Comptroller General
The Congressional Review Act, 5
U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996, generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report, which includes a
copy of the rule, to each House of the
Congress and to the Comptroller General
of the United States. EPA will submit a
report containing this action and other
required information to the U.S. Senate,
the U.S. House of Representatives, and
the Comptroller General of the United
States prior to publication of the rule in
the Federal Register. A major rule
cannot take effect until 60 days after it
is published in the Federal Register.
This action is not a ‘‘major rule’’ as
defined by 5 U.S.C. 804(2).
C. Petitions for Judicial Review
Under section 307(b)(1) of the CAA,
petitions for judicial review of this
action must be filed in the United States
Court of Appeals for the appropriate
circuit by February 21, 2025. Filing a
petition for reconsideration by the
Administrator of this final rule does not
affect the finality of this action for the
purposes of judicial review nor does it
extend the time within which a petition
for judicial review may be filed, and
shall not postpone the effectiveness of
such rule or action.

SUPPLEMENTARY INFORMATION: On August 16, 2024 (89 FR 66659), EPA
published a notice of proposed rulemaking (NPRM) for the State of
Delaware. In the NPRM, EPA proposed approval of a revision to the
Delaware SIP that consists of amendments to Title 7 of the Delaware
Administrative Code (7 DE Admin). Specifically, the amendments are to 7
DE Admin 1103 Ambient Air Quality Standards (DE 1103). DNREC's
amendments to DE 1103 aligned the language of that regulation to be
consistent with existing Federal regulatory standards. Specifically,
DNREC revised DE 1103 to reflect: the most current national ambient air
quality standards (NAAQS) for ground level ozone; amendments to update
citations in DE 1103 to include the CFR dates in effect at the time
DNREC amended DE 1103 for all NAAQS; and amendments to remove the
SO2 24-hour and annual primary standards. On May 14, 2024,
DNREC submitted a withdrawal letter to remove an update to section
1.6.5 of DE 1103 in Delaware's SIP. Delaware withdrew its revision to
section 1.6.5 because that regulation erroneously cites an EPA
analytical method that was revoked by EPA. The formal SIP revision was
submitted by Delaware on November 15, 2022. By a letter dated May 14,
2023, Delaware withdrew a portion of the submission that referenced an
obsolete EPA monitoring methodology.
I. Background
The CAA mandates that the EPA set NAAQS for criteria pollutants,
which are ozone and related photochemical oxidants, carbon monoxide,
lead, nitrogen oxides, particulate matter, and sulfur oxides. The CAA
also requires EPA to periodically review the relevant scientific

II. Summary of SIP Revision and EPA Analysis
Delaware's November 15, 2022 SIP submission consists of: (1)
amendments to its ambient air quality standards in DE 1103 to reflect
the current NAAQS for ground level ozone; (2) amendments to its
regulatory citations to the CFR dates for the EPA sampling and
analytical procedures and techniques for the various NAAQS that
Delaware incorporates into its regulations, and (3) amendments to
remove from DE 1103 the SO2 24-hour and annual primary
standards that have been revoked by EPA. Delaware's regulatory
amendments aligned DE 1103 with current EPA's NAAQS regulations. By
including these revisions to DE 1103 in the Delaware SIP, the SIP will
also align with EPA's current NAAQS regulations.
The Delaware SIP's current primary and secondary ozone NAAQS
standards are outdated at 0.075 ppm. DNREC's revision to DE 1103
updated the primary and secondary ozone standards in section 6.0 of DE
1103 to reflect the 2015 Ozone NAAQS of 0.070 ppm. This approval action
for Delaware's SIP submittal will make the SIP consistent with EPA's
current ozone NAAQS.
DNREC has also amended DE 1103 to update its references to the
dates for EPA's sampling and analytical procedures and techniques for
the various NAAQS, that Delaware incorporates by reference into DE
1103. The dates, for all sections except 1.6.5, are updated to July 1,
2019, which was the most current version of the CFR as of the time that
DNREC revised DE 1103. This approval action will incorporate into
Delaware's SIP the NAAQS monitoring methodologies as codified in the
2019 CFR, which was the
[[Page 104432]]
most recent version of the CFR at the time Delaware revised DE 1103.
Updating these references will strengthen the Delaware SIP.
Additionally, Delaware removed subsections 4.2 and 4.3 from DE
1103. These subsections had set forth Delaware's SO2 24-hour
primary standard and SO2 annual primary standard, which
corresponded to the EPA's revoked SO2 24-hour primary
standard and SO2 annual primary standard. This amendment to
DE 1103 conforms the Delaware SO2 ambient air quality
standard with EPA's current Federal regulations. This approval action
will align Delaware's SIP with EPA's current SO2 NAAQS, at
40 CFR 50.17. No public comments were received on the NPRM.
III. Final Action
EPA is approving Delaware's submittal of November 15, 2022, as
modified by the letter dated May 14, 2023, as a revision to the
Delaware SIP.
IV. Incorporation by Reference
In this document, EPA is finalizing regulatory text that includes
incorporation by reference. In accordance with requirements of 1 CFR
51.5, EPA is finalizing the incorporation by reference of DE regulation
1103, as effective on July 1, 2019, excluding updates to section 1.6.5,
as discussed in sections I and II of this preamble. EPA has made, and
will continue to make, these materials generally available through
www.regulations.gov and at the EPA Region III Office (please contact
the person identified in the For Further Information Contact section of
this preamble for more information). Therefore, these materials have
been approved by EPA for inclusion in the SIP, have been incorporated
by reference by EPA into that plan, are fully federally enforceable
under sections 110 and 113 of the CAA as of the effective date of the
final rulemaking of EPA's approval, and will be incorporated by
reference in the next update to the SIP compilation.\4\

V. Statutory and Executive Order Reviews
A. General Requirements
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 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); and
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 Clean Air Act.
In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where 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).
Executive Order 12898 (Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations, 59 FR 7629,
February 16, 1994) directs Federal agencies to identify and address
``disproportionately high and adverse human health or environmental
effects'' of their actions on minority populations and low-income
populations to the greatest extent practicable and permitted by law.
EPA defines environmental justice (EJ) as ``the fair treatment and
meaningful involvement of all people regardless of race, color,
national origin, or income with respect to the development,
implementation, and enforcement of environmental laws, regulations, and
policies.'' EPA further defines the term fair treatment to mean that
``no group of people should bear a disproportionate burden of
environmental harms and risks, including those resulting from the
negative environmental consequences of industrial, governmental, and
commercial operations or programs and policies.''
DNREC did not evaluate environmental justice considerations as part
of its SIP submittal; the CAA and applicable implementing regulations
neither prohibit nor require such an evaluation. EPA did not perform an
E.J. analysis and did not consider E.J. in this proposed rulemaking.
Due to the nature of the proposed action being taken here, this
proposed rulemaking is expected to have a neutral to positive impact on
the air quality of the affected area. Consideration of EJ is not
required as part of this action, and there is no information in the
record inconsistent with the stated goal of E.O. 12898 of achieving
environmental justice for people of color, low-income populations, and
Indigenous peoples.
B. Submission to Congress and the Comptroller General
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this action and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2).
C. Petitions for Judicial Review
Under section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by February 21, 2025. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this action for the purposes of judicial review nor
does it extend the time within which a petition for judicial review may
be filed, and shall not postpone the effectiveness of such rule or
action.
[[Page 104433]]
This action approving amendments to Delaware's ambient air
standards may not be challenged later in proceedings to enforce its
requirements. (See section 307(b)(2).)
