OREGON NATIONAL GUARD TO DETONATE SMALL UNEXPLODED ORDNANCE
 
A contractor working for the Oregon National Guard will detonate a World War II-era mortar round Friday afternoon at Camp Withycombe in Clackamas, Ore.

Contract employees discovered the unexploded 60 mm mortar shell as they assessed the former small arms firing range for safety prior to starting a restoration project. The contractor will detonate the mortar on site to ensure safe disposal.

Before detonating the mortar, disposal personal will secure the area with sandbags and blast mats. These precautionary measures will limit any sound disturbance to the immediate area of the detonation.

Once the former range is cleared of unexploded ordnance, the restoration project will begin. The Oregon Military Department, in coordination with the Oregon Department of Environmental Quality and the Oregon Department of Transportation, will conduct the restoration through a contractor. Protecting human health and the environment are compatible concerns during the project. The restoration project will include the following activities:

- Identification and removal of ordnance debris
- Demolition of support buildings and concrete walls
- Clearing and grubbing of project range areas – approximately 10 acres
- Excavation of range soil – approximately 22,000 cubic yards
- Treatment of excavated soil using soil washing and stabilization
- Recycling of lead bullets
- Filling of excavations using treated soil
- Regrading of any affected Mount Talbert hill slope
- Planting native vegetation
- Restoration of wetlands
