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

East Mission Flats Update
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

Notes
1. ND - Not detected above method reporting limit
2. MCL - Maximum Contaminant Level - enforceable
3. NSDWR - National Secondary Drinking Water Regulation - non-enforceable
J - Reported concentration an estimate based on data quality review
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)
