10:05 P.M. 	Panel Members: Follow-Up on Previous Day  -  Daniel Schlenk, Ph.D., TSCA Science Advisory Committee on Chemicals (SACC) Chair

10:20 A.M. 	Charge Question 2: (includes a 15-minute break)

For instances where EPA is focused on the potential impact of a single release source (air 
or water release) for a given condition of use (COU), is it reasonable for EPA to use this screening level approach (Version 1.0) to conclude that chemical exposure from a single release source for a given COU is not a concern if exposure results of the methodology, when compared to relevant toxicological benchmarks, do not indicate any potential human health risks to fenceline communities? In your response, please provide examples or explanations to support your conclusions or suggestions 

12:45 P.M. 	Lunch Break

1:45 P.M 	Charge Question 3: (includes a 15-minute break)
                                        
 Keeping in mind that EPA's intent is to develop a screening level approach, please provide any practical suggestions you may have for enhancing Version 1.0 of EPA's screening level approach with respect to air and water release estimation, ambient and indoor air exposure estimation, and ambient surface water exposure estimation 

5:00 P.M.	Adjourn

10:05 P.M. 	Panel Members: Follow-Up on Previous Day Presentations  -  Daniel Schlenk, Ph.D., TSCA Science Advisory Committee on Chemicals (SACC) Chair

10:15 A.M. 	Charge Question 4:

 Please propose and describe approaches that EPA can take into consideration for the purposes of expanding the capacity of the proposed screening methodology (Version 1.0) presented in this work. Some possible examples may include but are not limited to: 
 
 Charge Question 4a:

 How the proposed screening level approach may be expanded to evaluate aggregate/cumulative exposures and whether additional sources of environmental release information (beyond the Toxics Release Inventory or TRI) should be considered for such enhancements (such as the National Emissions Inventory or NEI). 

11:30 A.M.		Break

11:45 P.M. 	Charge Question 4b:

How the proposed screening level approach may be expanded to identify potential environmental justice (EJ) concerns and inform future EJ analyses that assess racial and economic disparities in exposures.

1:00 P.M. 	Lunch

2:00 P.M. 	Charge Question 4c:
 
 How the proposed screening level approach may be expanded to evaluate exposures from additional pathways such as land disposal or groundwater contamination. 

3:15 P.M.	Break

3:30 P.M.	Charge Question 4d:

 How the proposed screening level approach may be expanded to evaluate exposures relevant to tribes, indigenous populations, subsistence lifestyles, cultural practices, or other unique circumstances. 
 
5:00 P.M.	Adjourn
