ENVIRONMENTAL PROTECTION AGENCY

[FRL-9224-7]

Workshop To Review Draft Materials for the Lead (Pb) Integrated 
Science Assessment (ISA)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Workshop.

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

SUMMARY: As part of the review of the air quality criteria and National 
Ambient Air Quality Standards (NAAQS) for Lead (Pb), EPA is announcing 
that a workshop to evaluate initial draft materials for the Pb 
Integrated Science Assessment (ISA) is being organized by EPA's 
National Center for Environmental Assessment (NCEA) within the Office 
of Research and Development. The workshop will be held on December 2 
and 3, 2010 in Research Triangle Park, NC and will be open to 
attendance by interested public observers on a first-come first-serve 
basis up to the limits of available space.

DATES: The workshop will be held on December 2 and 3, 2010 at 8 a.m. 
and end at 5 p.m.

ADDRESSES: The workshop will be held in the Auditorium of EPA's main 
campus, 109 T.W. Alexander Drive, Research Triangle Park, NC. The EPA 
contractor, Versar, is providing logistical support for the workshop.

FOR FURTHER INFORMATION CONTACT: Questions regarding information, 
registration, and logistics for the workshop should be directed to

SUPPLEMENTARY INFORMATION: 

I. Summary of Information About the Workshop

    Section 109-(d) of the Clean Air Act requires the U.S. 
Environmental Protection Agency (EPA) to conduct periodic reviews of 
the air quality criteria for each air pollutant listed under section 
108 of the Act. Based on such review, EPA is to retain or revise the 
NAAQS for a given pollutant as appropriate. As part of these reviews, 
NCEA assesses newly available scientific information and develops ISA 
documents (formerly known as Criteria Documents) that provide the 
scientific basis for the reviews of the NAAQS for Pb, particulate 
matter, carbon monoxide, nitrogen oxides, sulfur oxides, and ozone. 
Based on the information in the ISA, EPA's Office of Air Quality 
Planning and Standards typically conducts quantitative and qualitative 
risk and exposure assessments. The ISA and the risk/exposure 
assessments are used to prepare a policy assessment that informs 
subsequent rulemaking actions.
    NCEA-RTP is holding this workshop to inform the Agency's evaluation 
of the scientific evidence for the review of the NAAQS for Pb. The 
purpose of the workshop is to obtain review of the scientific content 
of initial draft materials or sections for the draft ISA. Workshop 
sessions will include review and discussion of initial draft sections 
on the health effects evidence from in vivo and in vitro animal 
toxicology studies, and from epidemiology studies as well as evidence 
of the ecological effects of Pb. In addition, roundtable discussions 
will help identify key studies or concepts within each discipline to 
assist EPA in integrating within and across disciplines. This workshop 
is intended to help ensure that the ISA is up-to-date and focuses on 
the key evidence to inform the scientific understanding for the review 
of the NAAQS for Pb. EPA is planning to release the first external 
review draft ISA for Pb for review by the Clean Air Scientific Advisory 
Committee and the public in May 2011.

II. Workshop Information

    Members of the public may attend the workshop as observers. Space 
is limited, and reservations will be accepted on a first-come, first-
serve basis.
