• Expedited, cost effective remedy consistent with the ROD objectives

– Reduce health hazards for people eating fish and crab by reducing theconcentrations of the chemicals in sediment

– Reduce the risks to ecological receptors by reducing the concentrations ofthe chemicals in sediment

– Reduce the migration of chemical-contaminated sediment to upstreamportions of the Lower Passaic River, Newark Bay, and the New York-NewJersey Harbor Estuary

OU2 Remedial Design Objectives

• Capping with dredging to prevent additional flooding in the lower 8.3

miles

• Deeper dredging in the lower 1.7 miles for navigational purposes

• Dredged materials to be disposed off-site

• Fish/crab consumption advisories remain in place

• Restrictions on dredging/anchoring to protect cap
