6. Purpose • Through the development and application of case studies, to additionally evolve the methodologies in specific areas and crosscutting issues raised by Science and Decisions Advancing Risk Assessment

7. Series of Three Workshops • Workshop I • Texas Commission on Environmental Quality, March 16-18, 2010 • Workshop II • Crystal City, Virginia (in tandem with the Federal & State Risk Assessment & Toxicology Committee), October 11-13, 2010 • Workshop III • Noblis; Falls Church, Virginia, May 4-6, 2011

8. Overview of Workshop Objectives • Build off the NAS (2009) report • to develop practical guidance for use by risk managers at a variety of levels • states, regional managers, a variety of agencies, and industry • for risk assessment techniques applicable to specific problem formulations. • Implement a multi-stakeholder approach to share information, ideas, and techniques in support of developing practical, problem-driven risk assessment guidance.

9. Workshop Materials • Workshop Notebook • Background • Agenda and Logistics • Bios • Case Study Summaries • Online • Framework • Full Case Studies • Presentation Slides

10. Housekeeping • Look around now for exits in case of fire • Cell phone reminder.... • Mid-morning and afternoon breaks • Lunch speakers scheduled and lunches provided on Wednesday and Thursday • The sessions are being webcast so remember there is a second audience listening on the phone. Please be mindful of their participation: • Use the mics to facilitate listening for those on webcast • Only one person speaking at a time • Identify yourself with name and affiliation when speaking

11. Beyond Science and Decisions: From Problem Formulation to Dose-Response. Workshop I Date: March 16-18, 2010 Location: Texas Commission on Environmental Quality

12. Workshop I Summary • 60 participants with more than 100 participants via webcast • Brainstorming • Ongoing risk assessment activities • Perspectives on the NAS (2008) Silver Book • Selection of case studies • Consideration and selection of case studies • Focus on the principles of the methodology, not specific chemicals

13. Workshop II/III Expert Panel • Provide guidance during the workshops • Evaluate the case studies during Workshop II/III • Use case studies to evolve methodologies and address cross-cutting issues raised in NAS Science & Decisions report • Balance across affiliation & expertise • Risk assessment and Toxicology

14. Panel Selection Process • Announcement of workshops, with a call for Panel nominations • DRAC also nominated panel member candidates • ARA Steering Committee reviewed candidates and developed a prioritized list of nominees • Invitations were sent to a total of 27 people • Particular effort was made to include people from the NAS, 2009 Panel & environmental NGOs

17. Activities between Workshops II & III • Panel reviewed the case studies • A draft risk framework was developed and posted on the ARA website • New case studies were proposed and submitted to the Panel for consideration • Panel used  framework to identify areas and methodological issues where additional illustrative case studies were needed • Those case studies were invited to be brought to Workshop III

23. ACC Center for Advancing Risk Assessment Science & Policy (ARASP) Perspective • Group of chemical-specific groups working towards improving risk assessment science and policy, given changing world of toxicology. • Accelerate the development, evaluation and use of weight-of-evidence frameworks, MOA analysis, & quantitative uncertainty methods in chemical risk assessments. • Support ARA-sponsored workshops to broaden & deepen scientific discussion on dose-response assessment & MOA • Contribute case studies / scientific data & analyses and actively participate in the scientific discourse of the ARA project.

24. TCEQ’s Perspective • Commissioner’s and executive management of the Texas Commission on Environmental Quality support these series of workshops • Environmental regulations should be meaningful and provide the most benefit to those who need help • Good science should lead the way and improve the process

25. EPA Perspective • The case studies being developed by this workshop series will be useful to the Agency as it moves forward in addressing the recommendations presented in Science and Decisions.
