Former Scott Paper Mill Environmental Cleanup

Project Overview

The Scott Paper Mill Cleanup project was a multi-phase project to reclaim and clean up the offshore and near-shore areas of the former Scott Paper facility. Project was performed under the MTCA Program in full coordinated with the U.S. Army Corp of Engineers and Department of Ecology.

Project Highlights

  • 84,000 CY of contaminated Subtitle D material was environmentally dredged and placed on flat decks using environmental-sealed bucket to be transported for upland disposal.
  • 20,000 CY of clean material was dredged for open-water disposal to the Port Gardner DMMP unconfined open-water disposal site.
  • PPM performed an eelgrass limit survey to confirm the existing limits of eelgrass within the project area to identify proposed navigational access corridors to minimize potential damage to existing established eelgrass beds during construction.
  • Dredging and capping were primarily performed using a barge mounted Hitachi 1200 hydraulic excavator equipped with an articulating clam shell bucket.
  • Environmental marine cap was placed over the shoreline where remedial excavations occurred.
