The Environmental Protection Agency has issued Occidental Chemical Corp. an order to design an interim cleanup plan for the upper nine miles of the Lower Passaic River Study Area of the Diamond Alkali Superfund site in New Jersey, according to the agency Thursday.
The cleanup plan includes capping and dredging of roughly 387,000 cubic yards of contaminated sediment, evaluating areas where sediments can be dredged, and monitoring and maintaining the cap.
The company will also assess the river bottom, shoreline, and other aspects of the river to prepare for the cleanup, EPA said.
