regulation of combined sewer outfalls; 



regulation of other point sources and stormwater outfalls; and 



control of non-point sources, such as river flow, overland runoff, 

 and groundwater inflow. 



Controlling municipal sources of discharge into the estuary is of 

 primary importance, since these sources represent a significant portion of 

 the pollutant input to the Bight Apex. Figure 2 shows the location of 

 municipal sewerage treatment plants in the metropolitan area. Currently, 

 2.02 billion gallons per day of treated sewage are discharged from these 

 plants; 133 million gallons of which receive primary treatment prior to 

 discharge; 517 million gallons, modified secondary treatment; and 1,366 

 million gallons, secondary treatment. In addition, about 250 million 

 gallons a day are discharged untreated (raw) in the North River and Red Hook 

 areas of New York City. Major efforts have been made to meet the Clean 

 Water Act's requirement of secondary treatment for municipal wastewaters. 

 Funds spent (both Federal and local) for the planning, design, and 

 construction of new or upgraded sewerage treatment facilities in the 

 metropolitan area have totalled nearly $6 billion. Also, the ongoing 

 construction of sewerage treatment facilities to service the North River and 

 Red Hook areas of New York City where untreated sewage is discharged, is 

 being completed under court order.
