The Scott Paper Mill Project was a multi-phase project to clean up the offshore and near-shore areas of the former Scott Paper facility. Sampling showed soil contamination was present to a depth of 15-ft and spread offshore several hundred feet.
20,000 CY of clean material was dredged for open water disposal. 84,000 CY of contaminated Subtitle D material was environmentally dredged and placed on flat decks using an environmental-sealed bucket to be transported for upland disposal. 38,000 CY of clean material were dredged and placed as backfill. 43,000 tons of environmental capping material were placed.
Dredging was primarily performed using a Hitachi 1200 excavator mounted on a spud barge. The excavator was equipped with RTK GPS and boom angle sensors in combination with Dredgepack navigational software.
1,000-ft of rock breakwater was also constructed using a Hitachi 270 excavator outfitted with Topcon RTK control.
