  2. Project Context Project Background Green Remedy Selection Implementation Final Numbers Summary Outline

  3. Project Context • ODOTand Clackamas County propose to build a new, east-west oriented, limited-access highway between Interstate 205 and the Rock Creek Junction.

  4. Project Context • The highway corridor transects Camp Withycombe, an Oregon Army National Guard Installation.

  5. Project Context • Soil impacted within highway corridor by small arms firing ranges. • Land within highway corridor potentially contains UXO. • Land within natural area potentially contains UXO.

  6. Project Background • First Camp Withycombe range built in 1909. • Expanded to seven ranges. • Use of ranges discontinued in 2007. • Oregon DEQ was lead regulatory agency. • Other Stakeholders include ODOT, ODFW, USFWS, Clackamas County, SHPO, DSL, and USACE

  7. Green Remedy Selection • Sustainability Components • Energy Requirements • Air Emissions • Impacts on Water Resources • Land and Ecosystem Impacts • Material Consumption • Waste Generation • Future Beneficial Land Use • Long-term Stewardship

  8. Green Remedy Selection • DEQ and OARs • Green Remediation Benefits Quantitative • Feasibility Study Acceptance Highly Dependent on the DEQ Project Manager • Rules do not consider: • social, cultural, and ecological habitat impacts associated with remedy implementation • Feasibility Studies • Protectiveness • Effectiveness • Long-Term Reliability • Implementability • Implementation Risk • Reasonableness of Cost

  9. Green Remedy Selection • Feasibility Studies • Remedial Action Alternatives • No Action • In-Place Containment with Institutional Controls • Excavation with Off-Site Disposal of Untreated HW Soil (dig & haul - presumptive remedy) • Excavation with Off-Site Disposal of Stabilized Treated Soil • Excavation with Ex-Situ Soil Treatment and On-Site Reuse Beneath Asphalt Cap • Excavation with Ex-Situ Soil Treatment Using Stabilization and On-Site Reuse • Treatability Studies • Estimated Lead Removal Efficiency • Estimated Quantity Available for Reuse • Effectiveness of Stabilization Agent (Phosphate)

  10. Implementation Pre-Screen, 2” Plus Dry Screen Gravity Separation Phosphate Amendment

  11. Implementation Former KD Range

  12. Implementation Soil Treatment Plant

  13. Implementation 800 mg/kg or less soil piles ready for reuse at AFRC MILCONProject

  14. Implementation Bullet Fraction Ready for Recycling – Stored in 1-ton Capacity Recycled Sugar Sacks

  15. Final Numbers • Converted nearly 30,000 tons of hazardous waste into reusable material, at a cost savings of more than $5 million • Recovered about 270 tons of lead bullets for recycling • Created 4,400 tons of structural fill, at cost savings of about $150,000 • Treated 7,145 tons of material to level suitable for reuse in project area, at a cost savings of about $228,400

  16. Final Numbers • Donated whole trees to Oregon Department of Fish and Wildlife for use in stream habitat restoration projects and 25 trees to the Outdoor Forestry Learning Center • Relocated over 100 trees creating native habitat during reforestation • Treated and reused all treatment process water for irrigation • Recycled asphalt and base rock from one-acre treatment pad • Recycled 62 tons of scrap metal and steel generated during project

  17. Final Numbers • Eliminated more than 1,480 truck trips through the Columbia RiverGorge National Scenic Area, preventing: • 355,200 truck miles • 83,000 gallons of diesel fuel, at a cost savings of about $415,000 • 914 pounds of particulate matter • 1,859,200 Pounds of CO2 • 36,543 pounds of NOx • 1,672 pounds of SOx

  18. Summary • Recycled many materials and wastes generated during project. • Drastically reduced quantity of fossil fuels required, and avoided discharge of air pollutants in the Columbia Gorge National Scenic Area. • Saved ORARNG nearly $6 million as compared to traditional hog and haul.
