Notice of Workshop.
EPA is announcing a workshop, organized by EPA's National Center for Environmental Assessment (NCEA) within the Office of Research and Development, to explore the possible ways by which mode-of-action and toxicity pathways approaches may contribute to interpretation of cumulative human health risks of the criteria air pollutants. The workshop will be held on May 31, 2012, in Research Triangle Park, North Carolina and will be open to attendance by interested public observers on a first-come, first-served basis up to the limits of available space.
The workshop will be held on May 31, 2012, beginning at 8:00 a.m. and ending at 5:00 p.m.
The workshop will be held in the auditorium of EPA's main campus, 109 T.W. Alexander Drive, Research Triangle Park, North Carolina. An EPA contractor, ICF International, is providing logistical support for the workshop.
Questions regarding information, registration, and logistics for the workshop should be directed to Whitney Kihlstrom, ICF International, Conference Coordinator, 2222 East NC–54, Suite 480, Durham, North Carolina 27713; telephone: 919–293–1646; facsimile: 919–293–1645; email:
Sections 108 and 109 of the Clean Air Act require periodic review and, if appropriate, revisions of the National Ambient Air Quality Standards (NAAQS) and the air quality criteria on which they are based. As a part of this process, NCEA reviews and integrates scientific information from across scientific disciplines in drawing conclusions related to exposure and health impacts of each of the criteria air pollutants in the Integrated Science Assessment (ISA). EPA is planning the development of a companion assessment to the ISAs, the Multipollutant Science Assessment, whereby the health effects of exposure to a mixture of pollutants, principally the criteria air pollutants, may be systematically evaluated. To this end, EPA conducted a workshop in February 2011, entitled
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.
