2 marine waters due to the activities of man^whlch adversely 



3 affect, directly or indirectly, the growth, reproduction, 



4 behavior, physiological condition, and survival of food 



5 fish and shellfish." 



g The foregoing definition of water pollution 



^ does not, in our opinion, preclude the discharge of treated 

 g waste materials into public waters provided such treatment 

 Q is sufficient to prevent water quality impairment. We be- 

 lieve that all marine and estuarial waters of the State 

 jj are food fish and shellfish areas. Because total and 

 j2 immediate clean-up of each waste is difficult we recognize 

 J2 that it may be necessary to establish minimal marine water 

 j4 areas for purposes of dilution of emitted waste matter on 

 an interim basis. However, continuing reduction of all 

 sources of wastes should be required to the end that 

 dilution areas established could be reduced or eliminated. 

 jg Establishment of a marine dilution area, including its 

 jft location and delineation is a complex problem and each 



area should be considered as a separate entity. Limiting 

 factors on the quantity, concentration and type of dis- 

 charge should include but not be limited to the biota 

 present, velocity, direction and transport (volume) of 

 water currents, vertical mixing of the water, flushing 

 rate, volume and chemical characteristics of the water
