ENVIRONMENTAL PROTECTION AGENCY

[FRL-8246-4]


Workshop on Interpretation of Epidemiologic Studies of 
Multipollutant Exposure and Health Effects

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Workshop.

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

SUMMARY: EPA is announcing that a workshop entitled, ``Interpretation 
of Epidemiologic Studies of Multipollutant Exposure and Health 
Effects,'' is being organized by EPA's National Center for 
Environmental Assessment, Office of Research and Development, to be 
held on December 13 and 14, 2006, in Research Triangle Park, NC. The 
workshop will be open to attendance by interested public observers on a 
first-come, first-served basis up to the limits of available space.

DATES: The workshop will be held on December 13 and 14, 2006.

ADDRESSES: The workshop will be held at the Sheraton Hotel in Chapel 
Hill, NC. An EPA contractor, SAIC, is organizing the workshop. For 
further information on the workshop, contact Kristin Wheeler, SAIC 
Conference Coordinator, 11251 Roger Bacon Drive, Reston, VA 20190, 
telephone: 703-318-4535; facsimile: 703-318-4755; e-mail: 
[email protected].

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 Project/Document

    The U.S. Clean Air Act requires that EPA carry out periodic reviews 
of the National Ambient Air Quality Standards (NAAQS) for major 
``criteria'' air pollutants and to revise the NAAQS for a given 
pollutant, as appropriate. As part of these reviews, the National 
Center for Environmental Assessment, within EPA's Office of Research 
and Development (ORD), assesses the newly available scientific 
information in Science Assessment documents (formerly known as Criteria 
Documents) that provide the scientific basis for the reviews of the 
NAAQS for particulate matter (PM), ozone (O3), carbon 
monoxide (CO), nitrogen oxides (NOX), sulfur oxides 
(SOx), and lead (Pb).
    NCEA is holding this workshop to inform the Agency's evaluation of 
the science in the review of the NAAQS for all criteria pollutants. The 
workshop will address various issues involved in the interpretation of 
epidemiologic study results that are based on ambient air monitoring 
data. These include issues related to exposure assessment, 
multipollutant confounding and effect modification, statistical 
modeling and biological plausibility. Cross-cutting issues pertaining 
to evaluation of all of the criteria air pollutants will be examined, 
with emphasis to be placed on studies involving evaluation of 
multipollutant health risks.
    This workshop is planned to advance interpretation and 
understanding of criteria air pollutant health effects analyses in 
population-level epidemiologic studies, with a focus on multi-pollutant 
exposures. The principal goals of this workshop are to: (1) Assess 
issues related to the interpretation of the epidemiologic literature, 
particularly related to the use of centrally located air quality 
monitors; (2) discuss new methodology and approaches to advance future 
epidemiologic research in the areas of exposure error, confounding and 
effect modification by copollutants, and statistical modeling; and (3) 
evaluate the extent to which evidence from human clinical and animal 
toxicologic studies aids in interpretation of findings observed in the 
epidemiologic literature.

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-
served basis.
