ENVIRONMENTAL PROTECTION AGENCY

[EPA-HQ-ORD-2020-0701; FRL-9764-01-ORD]


Webinar Workshop To Obtain Input on Initial Draft Materials for 
the Lead (Pb) Integrated Science Assessment (ISA)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of workshop.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is preparing an 
Integrated Science Assessment (ISA) as part of the review of the 
primary and secondary National Ambient Air Quality Standards (NAAQS) 
for Lead (Pb). As part of the Pb review, EPA is announcing a public 
workshop to evaluate preliminary draft materials that will inform the 
development of the Pb ISA. The workshop is being organized by EPA's 
Center for Public Health and Environmental Assessment (CPHEA) within 
the Office of Research and Development and will be held by webinar and 
teleconference on May 26, June 7, June 22, and June 29, 2022. The 
workshop will be open to attendance by interested public observers on a 
first-come, first-served basis and participation will be by webinar and 
teleconference only.

DATES: The workshop will be held on May 26, June 7, June 22, and June 
29, 2022.

ADDRESSES: The workshop will be held by webinar and teleconference. The 
website information and call-in number for the webinar are available to 
registered participants. To register, visit https://www.epa.gov/isa/integrated-science-assessment-isa-lead.

SUPPLEMENTARY INFORMATION:

I. Information About the Workshop

    Section 108(a) of the Clean Air Act directs the Administrator to 
identify certain air pollutants which, among other things, ``cause or 
contribute to air pollution which may reasonably be anticipated to 
endanger public health or welfare''; and to issue air quality criteria 
for them. 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 [a] pollutant in the ambient air. . . 
.''. Under section 109 of the Act, EPA is then to establish NAAQS for 
each pollutant for which EPA has issued criteria. Section 109(d)(1) of 
the Act subsequently requires periodic review and, if appropriate, 
revision of existing air quality criteria to reflect advances in 
scientific knowledge on the effects of the pollutant on public health 
or welfare. EPA is also required to review and, if appropriate, revise 
the NAAQS, based on the revised air quality criteria (for more 
information on the NAAQS review process, see https://www.epa.gov/naaqs).
    CPHEA is holding a workshop to inform the Agency's evaluation of 
the scientific evidence for the review of Pb. The purpose of the 
workshop is to obtain input on the scientific content of preliminary 
draft materials that will inform the development of the draft ISA. 
Workshop sessions will include discussion of preliminary draft 
materials from subject areas which may include exposure assessment, 
toxicokinetics, toxicology, epidemiology, air quality/exposure, fate 
and transport, biogeochemistry, plant and animal physiology, 
ecotoxicology, and ecological population biology. These preliminary 
materials are not being released as an external draft, but will be 
provided to the panelists to guide discussions and inform the 
development of the draft ISA for Pb. This workshop is planned to help 
ensure that the ISA, once developed, is up-to-date and focuses on the 
key evidence necessary to inform the underlying scientific basis for 
the review of the Pb primary and secondary NAAQS. EPA is planning to 
release the first external review draft of the Pb ISA for review by the 
Clean Air Scientific Advisory Committee (CASAC) and the public in early 
2023.

II. Workshop Information

    Members of the public may attend the teleconference as observers. 
Space in the teleconference may be limited, and reservations will be 
accepted on a first-come, first-served basis. Registration for the 
workshop is available online at https://www.epa.gov/isa/integrated-science-assessment-isa-lead.
