The final ICR package will then be submitted to OMB for review and approval. At that time, the EPA will issue another Federal Register notice to announce the submission of the ICR to OMB and the opportunity to submit additional comments to OMB. Abstract: This ICR is for activities related to the implementation of the EPA’s Regional Haze Rule (2017 rule revision),1 for the period between September 30, 2023, and September 30, 2026, and renews the previous ICR. The Regional Haze Rule codified at 40 CFR parts 308 and 309, as authorized by sections 169A and 169B of the Clean Air Act, requires states to develop implementation plans to protect visibility in 156 federally protected Class I areas. Tribes may choose to develop implementation plans. For this period, all 50 states, the District of Columbia, and the U.S. Virgin Islands will be developing and submitting 2nd planning period progress reports pursuant to 40 CFR 51.308(g) and 40 CFR 51.309(d)(10). In accordance with the 2017 rule revision, the progress reports associated with the 2nd planning period are not required to be submitted as SIP revisions. Further, 13 states and the U.S. Virgin Islands will be developing and submitting periodic comprehensive implementation plan revisions for the 2nd planning period to comply with the regulations. Form Numbers: None. Respondents/affected entities: Entities potentially affected by this action are state, local and tribal air quality agencies, regional planning organizations and facilities potentially regulated under the Regional Haze Rule. Respondent’s obligation to respond: Mandatory [see 40 CFR 51.308(b), (f) and (g)]. Estimated number of respondents: 52 (total); 52 state agencies. Frequency of response: Approximately every 5 years. Total estimated burden: 14,459 hours (per year). Burden is defined at 5 CFR 1320.03(b). Total estimated cost: $850,478.38 (per year). There are no annualized capital or operation & maintenance costs. Changes in Estimates: There is decrease of 23,796 hours in the total estimated respondent burden compared with the ICR currently approved by OMB. This decrease in burden reflects changes in labor rates and changes in the activities conducted due to the normal progression of the program. In the currently approved ICR, the 1 Final Rule: Protection of Visibility: Amendments to Requirements for State Plans, 82 FR 3078, January 10, 2017. VerDate Sep<11>2014 17:54 Mar 30, 2023 Jkt 259001 estimated respondent burden assumed 50 states, the District of Columbia, and the U.S. Virgin Islands would be developing and submitting comprehensive State Implementation Plans (SIPs), which were due by July 31, 2021. In practice, 37 states and the District of Columbia submitted SIPs during the currently approved ICR period. Within the proposed ICR, the estimated respondent burden assumes that all 50 states, the District of Columbia, and the U.S. Virgin Islands will be developing and submitting progress reports by January 31, 2025, while 13 states and the U.S. Virgin Islands will be submitting outstanding periodic comprehensive SIP revisions.

SUPPLEMENTARY INFORMATION: ddrumheller on DSK120RN23PROD with NOTICES1 I. Information About the Document Section 108(a) of the Clean Air Act (the Act) directs the EPA Administrator to identify and list certain air pollutants that ‘‘may reasonably be anticipated to endanger public health or welfare’’ and ‘‘the presence of which in the ambient air results from numerous or diverse mobile or stationary sources.’’ The Act further directs the Administrator to issue air quality criteria for these 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 . . .’’ Under section 109 of the Act, EPA is then to establish NAAQS for each pollutant for which the Agency has issued air quality criteria. Section 109(d)(1) requires periodic review and, if appropriate, revision of air quality criteria and the NAAQS to reflect advances in scientific knowledge on the effects of the pollutant on public health or welfare. Information on EPA’s process for reviewing the air quality criteria and the NAAQS is available at https:// www.epa.gov/naaqs. EPA has established NAAQS for six criteria pollutants. Presently the EPA is reviewing the air quality criteria and NAAQS for Pb. As part of that review, EPA is preparing an updated ISA to reflect the latest scientific knowledge on the public health and welfare effects of Pb exposures, per section 108(a) of the Clean Air Act. When final, the ISA, in conjunction with additional technical and policy assessments, will provide the scientific foundation for EPA’s decisions on the adequacy of the current Pb NAAQS and, if appropriate, on potential alternative standards. The CASAC, an independent scientific advisory committee with review and advisory functions that are mandated by section 109(d)(2) of the Clean Air Act, VerDate Sep<11>2014 17:54 Mar 30, 2023 Jkt 259001 will provide an independent scientific review of the draft ISA. On July 7, 2020, (85 FR 40641), EPA formally initiated its current review of the air quality criteria for the health and welfare effects of Pb, requesting the submission of recent scientific information on specified topics. Key background information on the air quality criteria for the primary (healthbased) and secondary (welfare-based) NAAQS for Pb was summarized in Volume 1 of EPA’s ‘‘Integrated Review Plan for the Lead National Ambient Air Quality Standards,’’ and the general approach to developing the Pb ISA was incorporated into Volume 2 of EPA’s ‘‘Integrated Review Plan for the Lead National Ambient Air Quality Standards,’’ which was available for public comment (87 FR 13732, March 10, 2022) and was discussed by the CASAC at a publicly accessible teleconference consultation (87 FR 15985, March 21, 2022).1 Webinar workshops were held on May 26, June 7, June 22, and June 29, 2022, for invited EPA and external scientific experts to discuss initial Pb ISA draft materials and for the public to have an opportunity to listen in to these discussions (87 FR 27147, May 6, 2022). Input received during these webinar workshops aided in the development of the draft ISA for Pb being released at this time. The next step is for the CASAC to review the draft ISA and to discuss its review at a public meeting. This meeting will include an opportunity for members of the public to address comments to the CASAC for its consideration. A separate FRN will inform the public of the date and time of the CASAC meeting and of the procedures for public participation. II.

SUPPLEMENTARY INFORMATION:

I. Information About the Document

    Section 108(a) of the Clean Air Act (the Act) directs the EPA 
Administrator to identify and list certain air pollutants that ``may 
reasonably be anticipated to endanger public health or welfare'' and 
``the presence of which in the ambient air results from numerous or 
diverse mobile or stationary sources.'' The Act further directs the 
Administrator to issue air quality criteria for these 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 . . .'' Under section 109 
of the Act, EPA is then to establish NAAQS for each pollutant for which 
the Agency has issued air quality criteria. Section 109(d)(1) requires 
periodic review and, if appropriate, revision of air quality criteria 
and the NAAQS to reflect advances in scientific knowledge on the 
effects of the pollutant on public health or welfare. Information on 
EPA's process for reviewing the air quality criteria and the NAAQS is 
available at https://www.epa.gov/naaqs.
    EPA has established NAAQS for six criteria pollutants. Presently 
the EPA is reviewing the air quality criteria and NAAQS for Pb. As part 
of that review, EPA is preparing an updated ISA to reflect the latest 
scientific knowledge on the public health and welfare effects of Pb 
exposures, per section 108(a) of the Clean Air Act. When final, the 
ISA, in conjunction with additional technical and policy assessments, 
will provide the scientific foundation for EPA's decisions on the 
adequacy of the current Pb NAAQS and, if appropriate, on potential 
alternative standards. The CASAC, an independent scientific advisory 
committee with review and advisory functions that are mandated by 
section 109(d)(2) of the Clean Air Act, will provide an independent 
scientific review of the draft ISA.
    On July 7, 2020, (85 FR 40641), EPA formally initiated its current 
review of the air quality criteria for the health and welfare effects 
of Pb, requesting the submission of recent scientific information on 
specified topics. Key background information on the air quality 
criteria for the primary (health-based) and secondary (welfare-based) 
NAAQS for Pb was summarized in Volume 1 of EPA's ``Integrated Review 
Plan for the Lead National Ambient Air Quality Standards,'' and the 
general approach to developing the Pb ISA was incorporated into Volume 
2 of EPA's ``Integrated Review Plan for the Lead National Ambient Air 
Quality Standards,'' which was available for public comment (87 FR 
13732, March 10, 2022) and was discussed by the CASAC at a publicly 
accessible teleconference consultation (87 FR 15985, March 21, 
2022).\1\
---------------------------------------------------------------------------

    \1\ Volume 3 of the IRP will describe key considerations in 
EPA's planning for any exposure/risk analyses. Volume 3 will also be 
the subject of a future consultation with the CASAC.
---------------------------------------------------------------------------

    Webinar workshops were held on May 26, June 7, June 22, and June 
29, 2022, for invited EPA and external scientific experts to discuss 
initial Pb ISA draft materials and for the public to have an 
opportunity to listen in to these discussions (87 FR 27147, May 6, 
2022). Input received during these webinar workshops aided in the 
development of the draft ISA for Pb being released at this time.
    The next step is for the CASAC to review the draft ISA and to 
discuss its review at a public meeting. This meeting will include an 
opportunity for members of the public to address comments to the CASAC 
for its consideration. A separate FRN will inform the public of the 
date and time of the CASAC meeting and of the procedures for public 
participation.

    Instructions: Direct your comments to Docket ID No. EPA-HQ-ORD-
2020-0701. Please ensure that your comments are submitted within the 
specified comment period. Comments received after the closing date will 
be marked ``late,'' and will only be considered if time permits. It is 
EPA's policy to include all materials it receives in the public docket 
without change and to make the materials available online at 
www.regulations.gov, including any personal information provided, 
unless materials include information claimed to be Confidential 
Business Information (CBI) or other information whose disclosure is 
restricted by statute. Do not submit information that you consider to 
be CBI or otherwise protected through www.regulations.gov or email. The 
www.regulations.gov website is an ``anonymous access'' system, which 
means EPA will not know your identity or contact information unless you 
provide it in the body of your comment. If you send an email directly 
to EPA without going through www.regulations.gov, your email address 
will be automatically captured and included as part of the materials 
that are placed in the public docket and made available on the 
internet. If you submit electronic materials, EPA recommends that you 
include your name and other contact information in the body of your 
materials and with any disk or CD-ROM you submit. If EPA cannot read 
your materials due to technical difficulties and cannot contact you for 
clarification, EPA may not be able to consider the materials you 
submit. Electronic files should avoid the use of special characters, 
any form of encryption, and be free of any defects or viruses. For 
additional information about EPA's public docket visit EPA's Docket 
Center homepage at https://www.epa.gov/dockets.
    Docket: Documents in the docket are listed in the

e.g., CBI or other information whose disclosure is restricted by 
statute. Certain other materials, such as copyrighted material, are 
publicly available only in hard copy. Publicly available docket 
materials are available either electronically in www.regulations.gov or 
in hard copy at the ORD Docket in the EPA Headquarters Docket Center.
