The work will occur during daylight hours only, seven days per week, and will not be conducted during hazardous sea or weather conditions. Survey activity will extend from Cheesequake Creek across the Raritan, Chapel Hill, and Ambrose channels, with the survey area beginning near 40° 28' 07.352\" N, 074° 15' 20.287\" W and ending near 40° 31' 25.423002\" N, 073° 51' 43.105434\" W.\nThe M/V BELLA MARIE is a 40-foot power catamaran survey vessel. During operations, the vessel will tow survey equipment behind and beneath it, including equipment that may extend up to 250 feet astern, which will restrict the vessel’s maneuverability. Mariners operating near the survey vessel should use caution, maintain a safe distance, and proceed at reduced speed.

Work will be conducted from a dive vessel, tug Manhasset Bay, and marker buoys, with vessel communications managed via VHF channels 16 and 65. The operation involves installing location buoys along the 84-inch outfall pipeline, which extends approximately two miles offshore and branches into an east-west diffuser field, each leg measuring about 1,225 feet. Commercial divers will mark the pipeline alignment to facilitate inspection and construction. The four key coordinates of the diffuser field are: 40.567939°N, 73.454662°W; 40.562960°N, 73.452567°W; 40.566250°N, 73.438921°W; and 40.571250°N, 73.441111°W.
