Outline
2011 TRB Workshop 3
ODOT and Clackamas County propose to build a new, east-west oriented, limited-access highway between Interstate 205 and the Rock Creek Junction.
Project Context
2011 TRB Workshop 4
The highway corridor transects Camp Withycombe, an Oregon Army National Guard Installation.
Project Context
2011 TRB Workshop 5
Soil impacted within highway corridor by small arms firing ranges.
Land within highway corridor potentially contains UXO. Land within natural area potentially contains UXO.
Project Context
2011 TRB Workshop 6
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

Green Remedy Selection
Feasibility Studies Protectiveness Effectiveness Long-Term Reliability Implementability Implementation Risk Reasonableness of Cost
2011 TRB Workshop 9
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)

Implementation
Bullet Fraction Ready for Recycling – Stored in 1-ton Capacity Recycled
Sugar Sacks
2011 TRB Workshop 15
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
Final Numbers
2011 TRB Workshop 16
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
Final Numbers
2011 TRB Workshop 17
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
Final Numbers
2011 TRB Workshop 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.
