All times noted are Eastern Standard Time. All meetings are 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.                

## 1. EC/NATA Review Panel Conference Call—May 14, 2001

The NATA Review Panel will conduct a public conference call on Monday, May 14, 2001 from 11 a.m. to 1 p.m. (Eastern Standard Time). The call will be hosted out of the EPA Science Advisory Board Conference Room (Room 6013), Ariel Rios Federal Building, 1200 Pennsylvania Avenue, NW., Washington, DC 20004. Interested members of the public may attend in person or connect to the conference by phone. The purpose of the call is to provide Panel Members with the opportunity to reach closure on their draft report. See below for details of the review, to request any supplemental materials from the Agency or ask questions on materials already received from the Agency

                    The NATA Review Panel is planning to have a closure discussion on its draft report in review of the EPA Document entitled “National-Scale Air Toxics Assessment for 1996,” EPA-453/R-01-003, dated January, 2001 and supporting appendices. This document represents an initial national-scale assessment of the potential health risks associated with inhalation exposures to 32 air toxics identified as priority pollutants by the Agency's Integrated Urban Air Toxics Strategy, plus diesel emissions. More information about the previous meetings can be found in 66 FR  9846, February 12, 2001. The NATA Review Panel is commenting on the charge questions which were outlined in the above                     **Federal Register**                     notice and pertain to appropriateness of the overall approach, including the data, models, and methods used, and the ways these elements have been integrated, as well as to suggest ways to improve these approaches for subsequent national-scale assessments.                

### Providing Public Comments

The NATA Review Panel will be accepting oral or written public comments at the conference call, but is asking participants to focus on three aspects of the SAB NATA Panel's draft report, namely: (1) Has the NATA Review Panel adequately responded to the questions posed in the charge?; (2) Are any statements or responses made in the draft unclear?; and, (3) Are there any technical errors? Oral and written public comments were previously accepted at the March 20-21, 2001 meeting in review of this topic.
