Industrial dischargers accounting for an estimated 275 million gallons 

 per day (excluding cooling waters) directly to the estuarine system are 

 being required under the Clean Water Act to implement technology-based 

 effluent limits in NPDES permits to control the discharge of pollutants into 

 the estuary. Furthermore, pretreatment programs are being developed to 

 remove toxic constituents from industrial discharges to municipal systems. 

 Approved local pretreatment programs to protect the treatment system from 

 upset due to these toxic constituents and to improve the quality of both the 

 effluent and sludge are required by July 1, 1983. As well, categorical 

 pretreatment standards which set limitations on toxic pollutant discharges 

 for specific industries are being promulgated by EPA in accord with a court- 

 approved timetable. 



Concurrent with the technology-based requirements, the Act authorizes 

 States to develop water-quality standards to ensure aquatic life and human 

 health protection. In order to meet these water-quality standards. States 

 may require more stringent effluent limits or levels of treatment by 

 municipalities and industries. 



Pursuant to these provisions, the States of New York and New Jersey 

 have established water-use classifications and criteria necessary for each 

 use, for the estuary and coastal waters in the metropolitan area (Figure 3). 

 Note these standards only apply to territorial waters (up to 3 miles) and 

 not to ocean waters. These use classifications and criteria, which have
