With the Secretary’s approval of the new ESL tests in the July 2023 notice, the new educational functioning levels for ESL described in appendix A of Measures and Methods for the National Reporting System for Adult Education (OMB Control Number: 1830–0027) were implemented. Under the transition rules in § 462.4, the Secretary also announced in the July 2023 notice a list of tests with NRS approvals expiring on February 2, 2024, and March 7, 2024, that States and local eligible providers may continue to use during a sunset period ending on June 30, 2024. In this notice, under the transition rules in § 462.4, the Secretary announces that the sunset period for ESL tests scheduled to sunset on June 30, 2024, is extended through June 30, 2025. This extension of the sunset period will allow States sufficient time for the operational activities required for the transition to the new ESL assessments identified in the July 2023 notice. The ESL educational functioning level descriptors to which the ESL tests with expiring NRS approvals are aligned and that were scheduled to be retired on June 30, 2024, are extended through June 30, 2025. Until that time, both the current ESL educational functioning level descriptors and the new ESL educational functioning level descriptors will be in effect. States must use an ESL assessment that is aligned to the appropriate ESL educational functioning level descriptors. Adult education programs must use only the forms and computer-based delivery formats for the tests approved in this notice. If a particular test form or computer delivery format is not explicitly specified for a test in this notice, it is not approved to measure educational gain in the NRS. lotter on DSK11XQN23PROD with NOTICES1 Tests With NRS Approvals That Expired on February 2, 2024, Previously Allowed for Use in the NRS During a Sunset Period Ending on June 30, 2024, and Now Allowed for Use During an Extended Sunset Period Ending on June 30, 2025 The Secretary has determined that the following tests may be used at all ESL levels of the NRS during an extended sunset period ending on June 30, 2025: (1) Basic English Skills Test (BEST) Literacy.

II. Information About the Documents Two sections of the Clean Air Act (CAA or the Act) govern the establishment and revision of the NAAQS. Section 108 directs the Administrator to identify and list certain air pollutants and then issue ‘‘air quality criteria’’ for those pollutants. The air quality criteria are to ‘‘accurately reflect the latest scientific knowledge useful in indicating the kind and extent of all identifiable effects on public health or welfare which may be expected from the presence of such pollutant in the ambient air . . .’’ (CAA section 108(a)(2)). Under section 109 of the Act, the EPA is then to establish primary (health-based) and secondary (welfare-based) NAAQS for each pollutant for which the EPA has issued air quality criteria. Section 109(d)(1) of the Act requires periodic review and, if appropriate, revision of existing air quality criteria. Revised air quality criteria are to reflect advances in scientific knowledge on the effects of the pollutant on public health and welfare. Under the same provision, the EPA is also to periodically review and, if appropriate, revise the NAAQS based on the revised air quality criteria. The Act additionally requires the appointment of an independent scientific review committee that is to periodically review the existing air quality criteria and NAAQS and to recommend any new standards and revisions of existing criteria and standards as may be appropriate (CAA section 109(d)(2)(A)–(B)). Since the early 1980s, the Clean Air Scientific PO 00000 Frm 00016 Fmt 4703 Sfmt 4703 19309 Advisory Committee (CASAC) has fulfilled the requirement for an independent scientific review committee. Presently, the EPA is reviewing the health-based air quality criteria and primary NAAQS for oxides of nitrogen. The EPA’s call for information for this review was issued on December 9, 2022 (87 FR 75625), and requested the public’s assistance in identifying relevant scientific information for the review that has become available since the cutoff date for the 2016 ISA (i.e., March 2014).1 The documents announced in this notice have been developed as part of the integrated review plan (IRP) which is developed in the planning phase for the review. The documents have been prepared jointly by the EPA’s Center for Public Health and Environmental Assessment within the Office of Research and Development and the Office of Air Quality Planning and Standards within the Office of Air and Radiation. These documents will be available on the EPA’s website: https:// www.epa.gov/naaqs/nitrogen-dioxideno2-primary-air-quality-standards, accessible under ‘‘Planning Documents’’ from the current review. The IRP for the current review of the primary NAAQS for oxides of nitrogen will be comprised of three volumes. Volumes 1 and 2 are the subject of this notice. Volume 1 provides background information on the air quality criteria and standards for oxides of nitrogen and may serve as a reference by the public and the CASAC in their consideration of the subsequent two volumes. Volume 2 addresses the general approach for the review and planning for the integrated science assessment (ISA). Comments are solicited from the public on Volume 2, which will also be the subject of a consultation with the CASAC, to be announced in a separate Federal Register notice. This volume identifies policy-relevant issues in the review and describes key considerations in the EPA’s development of the ISA. Volume 3, which is not yet completed, is the planning document for quantitative analyses to be considered in the policy assessment (PA), including exposure and risk analyses, as warranted. In order that consideration of the availability of new evidence in the review can inform these plans, the development and public availability of Volume 3 will generally coincide with that of the draft ISA, and it will be the subject of a consultation with the CASAC at that time. 1 Information assessed in the ISA for the last review generally included studies published prior to March 2014, with some exceptions.

To provide general oversight and support to these programs, EPA requires that state agencies with Basic and Enhanced I/M programs collect two varieties of reports for submission to the Agency: • An annual report providing general program operating data and summary statistics, addressing the program’s current design and coverage, a summary of testing data, enforcement program efforts, quality assurance and quality control efforts, and other miscellaneous information allowing for an assessment of the program’s relative effectiveness; and • A biennial report on any changes to the program over the two-year period and the impact of such changes, including any deficiencies discovered and corrections made or planned. General program effectiveness is determined by the degree to which a program misses, meets, or exceeds the emission reductions committed to in the state’s approved SIP, which, in turn, must meet or exceed the minimum emission reductions expected from the relevant performance standard, as promulgated under 40 CFR part 51, subpart S, in response to requirements established in section 182 of the Clean Air Act. This information is used by EPA to determine a program’s progress toward meeting requirements under 40 CFR part 51, subpart S, and to provide background information in support of program evaluations. Additional information regarding the current renewal of this ICR as well as previous renewals can be found in Docket ID No. EPA–HQ–OAR–2008–0707.

II. Information About the Documents

    Two sections of the Clean Air Act (CAA or the Act) govern the 
establishment and revision of the NAAQS. Section 108 directs the 
Administrator to identify and list certain air pollutants and then 
issue ``air quality criteria'' for those pollutants. The air quality 
criteria are to ``accurately reflect the latest scientific knowledge 
useful in indicating the kind and extent of all identifiable effects on 
public health or welfare which may be expected from the presence of 
such pollutant in the ambient air . . .'' (CAA section 108(a)(2)). 
Under section 109 of the Act, the EPA is then to establish primary 
(health-based) and secondary (welfare-based) NAAQS for each pollutant 
for which the EPA has issued air quality criteria. Section 109(d)(1) of 
the Act requires periodic review and, if appropriate, revision of 
existing air quality criteria. Revised air quality criteria are to 
reflect advances in scientific knowledge on the effects of the 
pollutant on public health and welfare. Under the same provision, the 
EPA is also to periodically review and, if appropriate, revise the 
NAAQS based on the revised air quality criteria.
    The Act additionally requires the appointment of an independent 
scientific review committee that is to periodically review the existing 
air quality criteria and NAAQS and to recommend any new standards and 
revisions of existing criteria and standards as may be appropriate (CAA 
section 109(d)(2)(A)-(B)). Since the early 1980s, the Clean Air 
Scientific Advisory Committee (CASAC) has fulfilled the requirement for 
an independent scientific review committee.
    Presently, the EPA is reviewing the health-based air quality 
criteria and primary NAAQS for oxides of nitrogen. The EPA's call for 
information for this review was issued on December 9, 2022 (87 FR 
75625), and requested the public's assistance in identifying relevant 
scientific information for the review that has become available since 
the cutoff date for the 2016 ISA (i.e., March 2014).\1\ The documents 
announced in this notice have been developed as part of the integrated 
review plan (IRP) which is developed in the planning phase for the 
review. The documents have been prepared jointly by the EPA's Center 
for Public Health and Environmental Assessment within the Office of 
Research and Development and the Office of Air Quality Planning and 
Standards within the Office of Air and Radiation. These documents will 
be available on the EPA's website: https://www.epa.gov/naaqs/nitrogen-dioxide-no2-primary-air-quality-standards, accessible under ``Planning 
Documents'' from the current review.
---------------------------------------------------------------------------

    \1\ Information assessed in the ISA for the last review 
generally included studies published prior to March 2014, with some 
exceptions.
---------------------------------------------------------------------------

    The IRP for the current review of the primary NAAQS for oxides of 
nitrogen will be comprised of three volumes. Volumes 1 and 2 are the 
subject of this notice. Volume 1 provides background information on the 
air quality criteria and standards for oxides of nitrogen and may serve 
as a reference by the public and the CASAC in their consideration of 
the subsequent two volumes. Volume 2 addresses the general approach for 
the review and planning for the integrated science assessment (ISA). 
Comments are solicited from the public on Volume 2, which will also be 
the subject of a consultation with the CASAC, to be announced in a 
separate Federal Register notice. This volume identifies policy-
relevant issues in the review and describes key considerations in the 
EPA's development of the ISA. Volume 3, which is not yet completed, is 
the planning document for quantitative analyses to be considered in the 
policy assessment (PA), including exposure and risk analyses, as 
warranted. In order that consideration of the availability of new 
evidence in the review can inform these plans, the development and 
public availability of Volume 3 will generally coincide with that of 
the draft ISA, and it will be the subject of a consultation with the 
CASAC at that time.

[[Page 19310]]

    As described above, comments on Volume 2 of the IRP should be 
submitted to the docket by April 17, 2024. A separate Federal Register 
notice will provide details about the CASAC consultation meeting and 
the process for participation in the CASAC consultation on Volume 2. 
The EPA will consider the consultation comments from the CASAC and 
public comments on the IRP, Volume 2, in preparation of the ISA for 
Oxides of Nitrogen--Health Criteria. Volume 1 of the IRP, also being 
made available, provides background or contextual and historical 
material for this NAAQS review. These documents do not represent and 
should not be construed to represent any final EPA policy, viewpoint, 
or determination.
