3.0 Major Technical or Regulatory Issues
Periodic cleanup activities are undertaken to remove contaminated materials from this site whenever structures are upgraded or construction of new buildings takes place on this site. Prior to siting new buildings, the area under the former surface is excavated and sampled to evaluate potential chemical or radiological contamination under supervision of Oregon Department of Environmental Quality and the Oregon Public Health Divison. Gamma spectroscopy analysis is used to determine contamination levels and release limits for materials removed during these remedial activities in cooperation with the U.S. Environmental Protection Agency.
