 these waters so as lo render such waters harmful to fish or other a(|ualic life There shall be no 

 discharge to these waters which will cause the "pi I" of these waters to fall outside of the 5.5 tu

 which are harmful to iiiiinaiis, animals or a(|uatic life or which adversely affect any other water

 will raise the radiu-iiuclide concentrations above the standards established by the United Slates 

 INiblic Health Service as being acceptable for drinking water. Diese waters shall be free of any 

 matter or substance which alters the composition of bottom fauna, which adversely afl'ects the 

 physical or chemical nature of bottom material, or which interferes with (he propagation of 

 fish. 



lliere shall be no disposal of sewage, industrial wastes or other wastes in such waters, except 

 those which have received treatment for the adequate removal of waste constituents, including, 

 but not limited to, solids, color, turbidity, taste, odor and toxic material, such that these 

 treated wastes will not cause any violation of water quality standards or alter the usages of this 

 classification, nor shall such disposal of sewage or waste be injurious to aquatic life or cause it 

 to be dangerous for human consumption. 1'herc shall be no additional discharge of phosphorus 

 to waters of this classification, which discharge does not employ the best available technology 

 for phosphorus removal.

Oass SA, shall be suitable for ail clean water usages, including water contact recreation, and 

 fishing. Such waters shall be suitable for the harvesting and propagation of shellfish and for a 

 fish and wildlife habitat. [Iiese waters shall contain not less than 6.0 parts per million of 

 dissolved oxygen at all times. The median numbers of culiform bacteria in any scries of samples 

 representative of waters in the shellfish growing area or non-shellfish growing area shall not be 

 in excess of 70 per 100 milliliters, nor shall more than 107« of the samples exceed 230 coliform 

 bacteria per 100 milliliters. The median numbers of fecal coliform bacteria in any series of 

 samples representative of waters in the shellfish growing area or non-shellfish growing area shall 

 not be in excess of 14 per 100 milliliters, nor shall more than 10% of the samples exceed 43 

 fecal coliform bacteria per 100 milliliters.

There shall be no lloaling solids, settleable solids, oil or sludge deposits attributable to 

 sewage, industrial wastes or other wastes and no deposit garbage, cinders, ashes, oils, sludge 

 or other refuse. There shall be no discharge of sewage or other wastes, except those which 

 have received treatment for the adequate removal of waste constituents including, but not 

 limited to. soUds, color, turbidity, taste, odor or toxic material, such that these treated 

 wastes will not lower the standards or alter the usages of this classification, nor shall such 

 disposal of sewage or waste be injurious lo aquatic life or render such dangerous for human 

 consumption. 



lliere shall be no toxic wastes, deleterious substances, colored or other waste or healed 

 liquids discharged to waters of this cla.ssilication either singly or in combinations with other 

 substances or wastes in such amounts or at such temperatures as to be injurious to edible 

 fish or shellfish or to the culture or pro|ugation thereof, or which in any manner shall 

 adversely affect the llavor, color, odor or sanitary condition thereof; and otherwise none in 

 sufficient amounts to make the water^ unsafe or unsuitable lor bathing or impair the waters
