6. Purpose Statement – Work Group To: Fulfill the technical information and data needs of the Spokane River Regional Toxics Task Force (SRRTTF) as requested. In a way that: Allows for a common level of understanding on technical issues by all the members of the SRRTTF. Is responsive to the technical needs of and the direction provided by the SRRTTF. Provides work plans and other deliverables that are consistent with the direction provided by the SRRTTF. Provides data and assessments of that data in a form that can be used by the SRRTTF for planning of subsequent work efforts. So that: The SRRTTF can develop a comprehensive plan to make progress towards achieving the PCB water quality standard for the Spokane River.

7. Purpose Statement – Work Group • Guidance Requested • Single Task Work Group or “core” group? • Technical Consultant Interface for Task Force? • Upgrades • Upgrading additions or deletions? • Confirmation Requested • Approval of Purpose Statement?

9. Purpose Statement – Workshop To: Provide a forum for the open exchange of information on the current state of knowledge both nationally and locally related to PCB water quality issues and sources In a way that: Allows those involved (regulators, academia, and consultants) in PCB water quality in other geographic areas to discuss their activities and provide insights into what they have learned from their efforts in areas applicable to Spokane River issues. Provides for a detailed review of the Ecology collected data on PCB in the Spokane River and how that data was analyzed and used to develop the 2003- 2007 Source Assessment Report and other related reports. Provides for an update on source identification and control efforts actions within the Spokane River watershed. Provides the opportunity for SRRTTF members to have discussions with presenters. Provides the opportunity for SRRTTF members to “brainstorm” how learnings can best be used to identify future technical information and data needs. Provides the opportunity for consultants, academia, and other potential resources to be introduced to the Task Force’s future efforts. So that: All members have the opportunity to develop a common level of understanding prior to setting the technical direction for the SRRTTF’s activities.

12. “Conceptual Model”

13. Lake Coeur d’Alene Winter Runoff Flow Spring Runoff Flow Summer/Fall Flow Main Stem Point Sources Urban Stormwater Runoff Non-Urban Stormwater Runoff Urban Seasonal Snow Melt Non-Urban Seasonal Snow Melt Aquifer Recharge Aerial Deposition Tributaries Sediment Re-suspension Water Craft Biological Release River Water Column Sources

14. River Water Column Sinks • Main Stem • Aquifer Discharge • Sediment Deposition • Volatilization / Evapotranspiration • Biological Update

15. Workshop Session Template • Session Subject • What area of interest do we want to learn about? • Session Content • What do we want the focus of this session to be? • Session Outcomes • What do we want to learn from this session? • Session Presenters • Who do we know of that has done work in this area? • Session Duration • How much time should we provide?

16. Workshop Session Example • Session Subject • Aerial Deposition • Session Content • PCB contribution to a watershed from direct and indirect aerial deposition (rainfall / snow pack runoff) • Session Outcomes • Can PCB deposition in snowfall become a significant source during runoff? How can the contribution be quantified? • Session Presenters • Lisa Totten at Rutgers University • Session Duration • 30 minutes?

17. Planning Input • Identification of Priorities for Sessions • SRRTTF Member Input • Pareto Analysis of Input • Identification of Desired Outcomes • SRRTTF Member Input • Identification of Presenters • SRRTTF Member Input • Homework Assignment • Return input by March 2nd (close of business)

18. Planning Input • Data Collection Survey Form • Identify any additional sources or sinks • Identify your top five sources or sinks that you feel are of interest or are potentially significant • Provide your desired outcomes for the five identified sources or sinks • Identify anyone you think might be someone who could make a presentation on the source or sink identified
