The safety zone around dredging operations in Marcus Hook Range in the Delaware River remains in effect until on or about February 28, 2014. The Dredge ESSEX has transitioned to the downriver portion of Marcus Hook Range, south of the Sunoco Marcus Hook Refinery, to complete dredging operations. The safety zone includes all waters within a 150 yards radius of the Dredge ESSEX and all related dredging equipment. Vessels requesting to transit Marcus Hook Range shall contact the Dredge ESSEX on VHF channel 13 or 16, 30 minutes prior to arrival. Vessels shall then transit around the dredge project, utilizing the downriver portion of the Marcus Hook Anchorage below Sunoco Marcus Hook Refinery, while operating at the minimum safe speed necessary to maintain steerage and reduce wake.
