Request for Nominations of Candidates for Two Review Panels of the Clean Air Scientific Advisory Committee CASAC
Environmental Protection Agency EPA.
ACTION: Notice.
AGENCY:

The EPA Science Advisory Board SAB Staff Office requests public nominations of scientific experts for two ad hoc review panels of the Clean Air Scientific Advisory Committee CASAC. The review panels will provide advice through the chartered CASAC on the scientific and technical aspects of air quality criteria and the primary and secondary National Ambient Air Quality Standards NAAQS for lead and the secondary NAAQS for oxides of nitrogen, oxides of sulfur, and particulate matter PM.
DATES: Nominations should be submitted by September 29, 2021 per the instructions below.
FOR FURTHER INFORMATION CONTACT: Any member of the public wishing further information regarding this Notice and Request for Nominations may contact Mr. Aaron Yeow, Designated Federal Officer DFO, SAB Staff Office, by telephone/voice mail at 202 5642050
or via email at yeow.aaron@epa.gov.
General information concerning the CASAC can be found on the following website: https casac.epa.gov.
SUPPLEMENTARY INFORMATION:
Background: The CASAC was established pursuant to the Clean Air Act CAA Amendments of 1977, codified at 42 U.S.C. 7409d2, to review air quality criteria and NAAQS
and recommend to the EPA
Administrator any new NAAQS and revisions of existing criteria and NAAQS as may be appropriate. The CASAC shall also: Advise the EPA
Administrator of areas in which additional knowledge is required to appraise the adequacy and basis of existing, new, or revised NAAQS;
describe the research efforts necessary to provide the required information;
advise the EPA Administrator on the relative contribution to air pollution

concentrations of natural as well as anthropogenic activity; and advise the EPA Administrator of any adverse public health, welfare, social, economic, or energy effects which may result from various strategies for attainment and maintenance of such NAAQS. As amended, 5 U.S.C., App. Section 109d1 of the Clean Air Act CAA
requires that EPA carry out a periodic review and revision, as appropriate, of the air quality criteria and the NAAQS
for the six criteria air pollutants, including lead, oxides of nitrogen oxides, oxides of sulfur, and PM.
The CASAC is a Federal advisory committee chartered under the Federal Advisory Committee Act FACA. As a Federal Advisory Committee, the CASAC conducts business in accordance with the Federal Advisory Committee Act FACA 5 U.S.C. App.
2 and related regulations. The CASAC
and the CASAC Review Panels will comply with the provisions of FACA
and all appropriate SAB Staff Office procedural policies.
History of the Lead NAAQS Review:
With the publication of the National Ambient Standards for lead 81 FR
71906 on October 18, 2016, the Agency completed its most recent review of the lead NAAQS. The CASACs Lead Review Panel for that review was formed in July 2010 and completed its work in June 2013. In July 2020, the EPA publicly announced the initiation of the current primary and secondary NAAQS review for lead 85 FR 40641.
This Federal Register notice solicitation is seeking nominations for subject matter experts to serve on the CASAC Lead Review Panel for the next review of the lead NAAQS that began with a call for information in July 2020
85 FR 40641. The Panel will be charged with reviewing the science and policy assessments, and related documents, that form the basis for the EPAs review of the lead NAAQS, and will provide advice through the Chartered CASAC.
History of the Current Oxides of Nitrogen, Oxides of Sulfur, and PM
Secondary NAAQS Review: In August 2013, the EPA publicly announced the initiation of the NAAQS review for oxides of nitrogen and oxides of sulfur 78 FR 53452. In the Integrated Review Plan for the Secondary NAAQS for Ecological Effects of Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter IRP, EPA recognized the combined contribution of oxides of nitrogen, oxides of sulfur and PM to deposition of nitrogen and sulfur and the overlap of effects of these air pollutants on ecological systems. As such, EPA stated the plan to review the ecological effects

of these three criteria pollutants together in this review and the IRP was finalized in 2017 following consultation with the CASAC and the CASAC Secondary NAAQS Review Panel for Oxides of Nitrogen and Sulfur. The first and second drafts of the Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur and Particulate MatterEcological Criteria were released in 2017 and 2018 and reviewed by the CASAC and the CASAC
Secondary NAAQS Review Panel for Oxides of Nitrogen and Sulfur. The final ISA was published in 2020 85 FR
66328. In addition, EPA released the Review of the Secondary Standards for Ecological Effects of Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter: Risk and Exposure Assessment Planning Document in 2018 83 FR
42497, which the CASAC Secondary NAAQS Review Panel for Oxides of Nitrogen and Sulfur provided consultative advice on.
On March 31, 2021, the Administrator reset membership of the Chartered CASAC and existing CASAC panels, including the CASAC Secondary NAAQS Review Panel for Oxides of Nitrogen and Sulfur. On June 17, 2021, the new Chartered CASAC members were announced.
This Federal Register notice solicitation is seeking nominations for subject matter experts to serve on the CASAC Oxides of Nitrogen, Oxides of Sulfur, and PM Secondary NAAQS
Panel to review the Policy Assessment for the EPAs review of the Oxides of Nitrogen, Oxides of Sulfur, and PM
Secondary NAAQS, and will provide advice through the Chartered CASAC.
Request for Nominations: The SAB
Staff Office is seeking nominations of nationally and internationally recognized scientists with demonstrated expertise and research in the field of air pollution related to criteria pollutants.
For the Lead Panel, experts are being sought in the following fields, especially with respect to lead: Air quality;
environmental fate and transport;
exposure and biomarker assessment;
biokinetic modeling; toxicology;
epidemiology; risk assessment;
biostatistics; and ecology.
For the Oxides of Nitrogen, Oxides of Sulfur, and PM Secondary NAAQS
Panel, experts are being sought in the following fields, especially with respect to nitrogen oxides, sulfur oxides and PM: Ecological effects of atmospheric concentrations and deposition to terrestrial, wetland and aquatic ecosystems; ecosystem exposure and risk assessment/modeling; ecosystem service and resource valuation; and atmospheric sciences.
