Start Preamble

Pursuant to the Federal Advisory Committee Act, Public Law 92-463, notice is hereby given that the Environmental Health Committee (EHC) of the US EPA Science Advisory Board (SAB), will meet on August 30, 2000 in Courtroom B, at the International Trade Commission building, 400 E Street, SW., Washington DC. The meeting will begin 9:00 am and adjourn no later than 5 pm. All times noted are Eastern Daylight Time. The meeting is open to the public, however, seating is limited and available on a first come basis. Important Notice: Documents that are the subject of SAB reviews are normally available from the originating EPA office and are not available from the SAB Office—information concerning availability of documents from the relevant Program Office is included below.

Purpose of the Meeting

The Integrated Risk Information System (IRIS) data base contains EPA's consensus scientific position on potential adverse human health effects that may result from chronic exposure to specific agents in the environment. First publically available in 1988, the earliest IRIS assessments provided the results of the EPA deliberations culminating in consensus health hazard conclusions. Gradually the assessments included more of the details of the data and of the considerations which led to the consensus conclusions. Since 1995 (when the IRIS Pilot program was undertaken), EPA has taken several steps to ensure that the best available scientific information is included in IRIS assessments, including public requests for all relevant information to be submitted to EPA for consideration in the assessments, and external peer reviews of the assessments.

In response to a directive contained in an October 1999 report from Congress (HR 106-379) regarding EPA's appropriations for FY2000, EPA has evaluated the characterization of data variability and uncertainty in IRIS assessments. EPA's Office of Research and Development (ORD) National Center for Environmental Assessment (NCEA) first consulted with the SAB Executive Committee (EC) on Nov. 29, 1999, about a proposed approach to this study. This approach involved assembling a team of independent, qualified individuals, external to EPA, to evaluate a representative set of IRIS assessments. ORD/NCEA provided a progress report to the SAB at their March 2000 meeting (at which the EC suggested further enhancements to the study approach), and at the EC's July 12, 2000 meeting. The study undertaken reflects the SAB's advice on how best to proceed, given available resources and the Congress's deadline of October 2000.

Charge to the Committee

The Charge asks the EHC to respond to the following three questions:

(a) How well did the study conform to the study plan developed with the SAB EC (November 1999 and March 2000)?

(b) Does the SAB concur with the findings of the reviewers?

(c) What further improvements, if any, might the Agency make in IRIS documentation in response to the study results?

Availability of Review Materials

The principal review document, Characterization of Data Uncertainty and Variability in IRIS Assessments, Pre-Pilot vs Pilot/post-Pilot, is available on the Internet at the SAB website (​sab), or by request to Ms. Karen Hogan, phone (202) 564-3403, or by email to
