Geography Future Needs – 5 and 25-Year Time Frames Capacity Near-Term Needs Long Term Needs
Waste Management Areas
Waste Stream Definitions
Three types of waste soil: Institutional Controls Program (ICP)
- Homeowner demo and renovation projects - Commercial, infrastructure development
Basin Property Remediation Program
- Yard cleanup program
Ecological Remediation
- Upper Basin: mine sites and tailings - Lower Basin: river bed and bank deposits

Archaeological Monitoring Report
• •
•
•
No recorded sites on State Register at EMF site; 10 test pits excavated in July 2007, no cultural resources observed in any of the 10 pits; Cuttings from 12 drill holes were monitored in October 2007; no cultural resources observed in any of the 12 drill holes; and Recommend to have an archaeologist on-site to observe all excavations scheduled for the site.
East Mission Flats Update
Groundwater Monitoring – December 2007
- Four wells sampled - Water levels suggest flat surface; flow from NW to SE - No dissolved metal concentrations reported above drinking water standards (MCLs) - Existing soil contamination has no significant impact to groundwater - Underlying “native” soil sorbs leaching metals - Next sampling event in March 2008

East Mission Flats Update
Flood Monitoring
- Two level loggers installed this week - Hourly readings through June 2008 - Compare results to Cataldo Gaging Station to establish stagewater level relationship - Use data to compare to HEC RAS flood model - Incorporate results in 90% Design Report
East Mission Flats Update
Phase I Operations
- Phase I Design Report out for Agency comment - Scheduled limited opening in May 2008 - Limited to 20,000 cubic yards - ICP and Basin Yard Cleanup wastes - Need to construct security fence and gate - Scheduled to acquire additional property between EMF site and Canyon Road in March 2008
East Mission Flats Update
60% Design Report
- Draft Design Report completion in April 2008 - Begin 90% Design in Summer 2008 - Begin construction of full project in Summer 2009
East Mission Flats Update
Visual Simulations
- Simulations prepared for 7 observation points
- Two seasons: Fall (October 2007) Winter (December 2007)
