NorthStar performed this remediation project at a former tie treating facility located in Escanaba, Michigan. The scope of services consisted primarily of removing 10,525 cubic yards (cy) of impacted sediment from Lake Michigan and installation of a combination a 78,740 square foot (sf) Soil Bentonite Cutoff Wall (SBCW) and 17,280 sf Steel Sheet Pile Cutoff Wall (SSP). The dredge area extended up to 170 feet from the shore and was mechanically dredged from constructed riprap finger piers with a hydraulic clam shell bucket. Backfilling occurred from barges and from shore using a 105-foot truck-mounted telescoping conveyor belt (telebelt). SBCW and SSP installation occurred concurrently to complete the project in a short window before the onset of winter.
