AOC4

For over ten years, the Port has been involved in litigation involving soil and groundwater contamination at the base of Slip 2. This area of contamination is referred to as Area of Concern 4 (AOC4). The contamination in this area resulted from leaking underground storage tanks, pipes and other faulty infrastructure that were utilized for oil delivery to marine vessels on Pier 2 during the last century.

The Port is now nearing the end of the litigation process and is negotiating a solution with the responsible parties as well as with Oregon’s Department of Environmental Quality.

Next steps:

  • Final settlement negotiations
  • Final Engineering and Design
  • Permits
  • Request for Proposals (Construction)

Estimated completion date: December 2018
