Workshop To Review Initial Health Effects Draft Materials for the 
Ozone (O3) 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 Standard (NAAQS) for Ozone (O3), EPA is 
announcing that a workshop to evaluate initial draft materials for the 
health effects sections of the O3 Integrated Science 
Assessment (ISA) is being organized by EPA's National Center for 
Environmental Assessment (NCEA) within the Office of Research and 
Development (ORD). The workshop will be held on August 6, 2010, in 
Research Triangle Park, NC, and 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 August 6, 2010.

ADDRESSES: The workshop will be held in the auditorium of EPA's main 
campus, 109 T.W. Alexander Drive, Research Triangle Park, NC. An 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

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 O3, particulate matter, carbon 
monoxide, nitrogen oxides, sulfur oxides, and lead. Based on the 
information in the ISA, EPA's Office of Air Quality Planning and 
Standards (OAQPS) 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 
    NCEA-RTP is holding this workshop to inform the Agency's evaluation 
of the scientific evidence for the review of the NAAQS for 
O3. The purpose of the workshop is to obtain a review of the 
scientific content of initial draft materials or sections for the draft 
ISA. Workshop sessions will include a review and discussion of initial 
draft sections on the health effects evidence from in vivo and in vitro 
animal toxicology, human clinical, and epidemiology studies. 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 planned 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 O3. 
EPA is planning to release the first external review draft ISA for 
O3 for review by the Clean Air Scientific Advisory Committee 
(CASAC) and the public in November 2010.

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.
