Background and Purpose II. Evaluation of New Hampshire’s Submittal III. Proposed Action IV. Incorporation by Reference V. Statutory and Executive Order Reviews I. Background and Purpose On December 22, 2022, New Hampshire Department of Environmental Services (NH DES) submitted to EPA a SIP revision updating its Env-A 300, ‘‘Ambient Air Quality Standards’’. The State revised this regulation to incorporate into its SIP revised National Ambient Air Quality Standards (NAAQS). In its December 2022 SIP submittal, NH DES adopted the following: (1) Coarse fine particle (PM10) primary (health-based) and secondary (welfarebased) 24-hour standards of 150 micrograms per cubic meter (mg/m3), (2) Fine particle (PM2.5) primary annual standard of 12 mg/m3, (3) PM2.5 secondary annual standard of 15 mg/m3, (4) PM2.5 primary and secondary 24hour standards of 35 mg/m3, (5) Sulfur dioxide (SO2) primary 1hour standard of 75 parts per billion (ppb), (6) SO2 secondary 3-hour standard of 0.5 parts per million (ppm), (7) CO primary 8-hour standard of 9 ppm, (8) CO primary 1-hour standard of 35 ppm, (9) Nitrogen Dioxide (NO2) primary annual of 53 ppb, (10) NO2 primary 1-hour standard of 100 ppb, (11) NO2 secondary annual standard of 0.053 ppm (equivalent to 100 mg/m3), (12) Ozone primary and secondary 8hour standard of 0.070 ppm, (13) Lead primary and secondary rolling 3-month standard of 0.15 mg/m3. New Hampshire’s Env-A 300, ‘‘Ambient Air Quality Standards,’’ was originally approved into the New Hampshire SIP on March 15, 1983 (48 FR 10830). Updates to the rule were approved into the New Hampshire SIP on August 19, 1994 (59 FR 42766) and on June 24, 2014 (79 FR 35695). II. Evaluation of New Hampshire’s Submittal EPA has reviewed New Hampshire’s revised Env-A 300 and has determined that it is consistent with the NAAQS in 40 CFR part 50 for all standards except the PM2.5 primary annual standard. On March 6, 2024, EPA strengthened the PM2.5 primary annual standard to 9.0 mg/m3 (89 FR 16202). E:\FR\FM\11JYP1.SGM 11JYP1 56826 Federal Register / Vol. 89, No. 133 / Thursday, July 11, 2024 / Proposed Rules khammond on DSKJM1Z7X2PROD with PROPOSALS Pursuant to a May 16, 2024, letter to EPA from NH DES, within a year from the effective date of EPA’s conditional approval of the December 2022 submittal, the State commits to submitting a revision to Env-A 300 that includes the current primary annual standard for the PM2.5 NAAQS. Therefore, EPA proposes to approve all of New Hampshire’s revised rule, except for the primary annual PM2.5 standard, which we propose to conditionally approve. III. Proposed Action EPA proposes to approve most of New Hampshire’s revised Env-A 300, ‘‘Ambient Air Quality Standards,’’ submitted by the State on December 22, 2022, as a revision to the New Hampshire SIP. We propose to conditionally approve the primary annual PM2.5 standard, provided that the State submits in a timely manner the portion of Env-A 300 that includes the current EPA PM2.5 primary annual NAAQS of 9.0 mg/m3. EPA is soliciting public comments on the issues discussed in this proposal or on other relevant matters. These comments will be considered before EPA takes final action. Interested parties may participate in the Federal rulemaking procedure by submitting comments to this proposed rule by following the instructions listed in the ADDRESSES section of this Federal Register. Under section 110(k)(4) of the Act, EPA may conditionally approve a plan based on a commitment from the State to adopt specific enforceable measures by a date certain, but not later than 1 year from the date of approval. If EPA conditionally approves the commitment in a final rulemaking action, the State must meet its commitment to submit a revision to Env-A 300 that includes the current PM2.5 primary annual NAAQS. If the State fails to do so, this action will become a disapproval one year from the date of final approval. EPA will notify the State by letter that this action has occurred. At that time, this commitment will no longer be a part of the approved New Hampshire SIP. EPA subsequently will publish a document in the Federal Register notifying the public that the conditional approval automatically converted to a disapproval. If the State meets its commitment, within the applicable time frame, the conditionally approved submission will remain a part of the SIP until EPA takes final action approving or disapproving the new legislative authority. If EPA disapproves the new submittal, the conditionally approved regulation will also be disapproved at that time. If EPA VerDate Sep<11>2014 15:58 Jul 10, 2024 Jkt 262001 approves the submittal, the regulation will be fully approved in its entirety and replace the conditionally approved program in the SIP. IV. Incorporation by Reference In this document, the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference New Hampshire’s regulation Env-A 300, as discussed in Sections I and II of this preamble. The EPA has made, and will continue to make, these documents generally available through https:// www.regulations.gov and at the EPA Region 1 Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). V. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. See 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 proposed 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); • 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); PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 • 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 CAA. 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, Feb. 16, 1994) directs Federal agencies to identify and address ‘‘disproportionately high and adverse human health or environmental effects’’ of their actions on minority populations and low-income populations to the greatest extent practicable and permitted by law. 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.’’ NH DES 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 EJ analysis and did not consider EJ in this action. Due to the nature of the action being taken here, this action 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.

V. Statutory and Executive Order Reviews

I. Background and Purpose

    On December 22, 2022, New Hampshire Department of Environmental 
Services (NH DES) submitted to EPA a SIP revision updating its Env-A 
300, ``Ambient Air Quality Standards''. The State revised this 
regulation to incorporate into its SIP revised National Ambient Air 
Quality Standards (NAAQS).
    In its December 2022 SIP submittal, NH DES adopted the following:
    (1) Coarse fine particle (PM10) primary (health-based) 
and secondary (welfare-based) 24-hour standards of 150 micrograms per 
cubic meter ([mu]g/m\3\),
    (2) Fine particle (PM2.5) primary annual standard of 12 
[mu]g/m\3\,
    (3) PM2.5 secondary annual standard of 15 [mu]g/m\3\,
    (4) PM2.5 primary and secondary 24-hour standards of 35 
[mu]g/m\3\,
    (5) Sulfur dioxide (SO2) primary 1-hour standard of 75 
parts per billion (ppb),
    (6) SO2 secondary 3-hour standard of 0.5 parts per 
million (ppm),
    (7) CO primary 8-hour standard of 9 ppm,
    (8) CO primary 1-hour standard of 35 ppm,
    (9) Nitrogen Dioxide (NO2) primary annual of 53 ppb,
    (10) NO2 primary 1-hour standard of 100 ppb,
    (11) NO2 secondary annual standard of 0.053 ppm 
(equivalent to 100 [mu]g/m\3\),
    (12) Ozone primary and secondary 8-hour standard of 0.070 ppm,
    (13) Lead primary and secondary rolling 3-month standard of 0.15 
[mu]g/m\3\.
    New Hampshire's Env-A 300, ``Ambient Air Quality Standards,'' was 
originally approved into the New Hampshire SIP on March 15, 1983 (48 FR 
10830). Updates to the rule were approved into the New Hampshire SIP on 
August 19, 1994 (59 FR 42766) and on June 24, 2014 (79 FR 35695).

II. Evaluation of New Hampshire's Submittal

    EPA has reviewed New Hampshire's revised Env-A 300 and has 
determined that it is consistent with the NAAQS in 40 CFR part 50 for 
all standards except the PM2.5 primary annual standard. On 
March 6, 2024, EPA strengthened the PM2.5 primary annual 
standard to 9.0 [mu]g/m\3\ (89 FR 16202).

[[Page 56826]]

    Pursuant to a May 16, 2024, letter to EPA from NH DES, within a 
year from the effective date of EPA's conditional approval of the 
December 2022 submittal, the State commits to submitting a revision to 
Env-A 300 that includes the current primary annual standard for the 
PM2.5 NAAQS. Therefore, EPA proposes to approve all of New 
Hampshire's revised rule, except for the primary annual 
PM2.5 standard, which we propose to conditionally approve.

III. Proposed Action

    EPA proposes to approve most of New Hampshire's revised Env-A 300, 
``Ambient Air Quality Standards,'' submitted by the State on December 
22, 2022, as a revision to the New Hampshire SIP. We propose to 
conditionally approve the primary annual PM2.5 standard, 
provided that the State submits in a timely manner the portion of Env-A 
300 that includes the current EPA PM2.5 primary annual NAAQS 
of 9.0 [mu]g/m\3\.
    EPA is soliciting public comments on the issues discussed in this 
proposal or on other relevant matters. These comments will be 
considered before EPA takes final action. Interested parties may 
participate in the Federal rulemaking procedure by submitting comments 
to this proposed rule by following the instructions listed in the 
ADDRESSES section of this Federal Register.
    Under section 110(k)(4) of the Act, EPA may conditionally approve a 
plan based on a commitment from the State to adopt specific enforceable 
measures by a date certain, but not later than 1 year from the date of 
approval. If EPA conditionally approves the commitment in a final 
rulemaking action, the State must meet its commitment to submit a 
revision to Env-A 300 that includes the current PM2.5 
primary annual NAAQS. If the State fails to do so, this action will 
become a disapproval one year from the date of final approval. EPA will 
notify the State by letter that this action has occurred. At that time, 
this commitment will no longer be a part of the approved New Hampshire 
SIP. EPA subsequently will publish a document in the Federal Register 
notifying the public that the conditional approval automatically 
converted to a disapproval. If the State meets its commitment, within 
the applicable time frame, the conditionally approved submission will 
remain a part of the SIP until EPA takes final action approving or 
disapproving the new legislative authority. If EPA disapproves the new 
submittal, the conditionally approved regulation will also be 
disapproved at that time. If EPA approves the submittal, the regulation 
will be fully approved in its entirety and replace the conditionally 
approved program in the SIP.

IV. Incorporation by Reference

    In this document, the EPA is proposing to include in a final EPA 
rule regulatory text that includes incorporation by reference. In 
accordance with requirements of 1 CFR 51.5, the EPA is proposing to 
incorporate by reference New Hampshire's regulation Env-A 300, as 
discussed in Sections I and II of this preamble. The EPA has made, and 
will continue to make, these documents generally available through 
https://www.regulations.gov and at the EPA Region 1 Office (please 
contact the person identified in the FOR FURTHER INFORMATION CONTACT 
section of this preamble for more information).

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. See 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 
proposed 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);
     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 CAA.
    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, 
Feb. 16, 1994) directs Federal agencies to identify and address 
``disproportionately high and adverse human health or environmental 
effects'' of their actions on minority populations and low-income 
populations to the greatest extent practicable and permitted by law. 
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.''
    NH DES 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 EJ analysis and did not consider EJ in this action. Due 
to the nature of the action being taken here, this action 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.
