any other water use in this class. No radiuuctive matter oi subsluiice shall he pcrnulted in 

 these waters would be harnirul to humans, animal or aquatic life and there shall be no 

 disposal of any matter or substance which would result in radio-nucUde concentrations in 

 edible fish or other aquatic life thereby rendering them dangerous for human consumption. 

 These waters shall be free of any nutter or substance which alters the composition of 

 bottom fauna, which adversely affects the physical or chemical nature of bottom material, or 

 which interferes with the propagation of llsh or shelirish if indigenous to the area. 



Class Sli-l shall be suitable for all clean water usages including water contact recre- 

 ation, and risliing. Such waters shall be suitable for the harvesting and propagation of 

 shellfish, anu lor a I'isli and wildlife habitat. ITiese waters shall contain not less than 

 6.0 parts |H:r million of dissolved oxygen at all times. 1he median numbers of coliform 

 bacteria in any series of samples representative of waters in the shellfish growing area 

 shall not be in excess of 70 per 100 milliliters, nor shall more than 10% of the 

 samples exceed 230 co!iforin bacteria per 100 milliliters. The median numbers of fecal 

 coliform bacteria in any scries of samples representative of waters in the shellfish 

 growing area shall not be in excess of 14 per 100 milliliters, nor shall more than 10% ol llie 

 samples exceed 43 fecal coliform bacteria per IIX) niillihtcrs. In a non-shellfish growing area the 

 median numbers of coliform bacteria in a series of samples representative of the waters shall not 

 exceed 240 per 100 milliliters, nor shall more than 10% of the samples exceed 50 coliloriii 

 bacteria per 100 milliliters. In a non-slielll'ish growing area the median numbers of fecal coli- 

 form bacteria in a series of s;-mplcs representative of the waters shall not exceed 50 per 100 

 milliliters, nor shall more than 10% of the samples exceed ISO fecal coliform bacteria |>er 100 

 milliUters. 



1977, c. 373, §8. 



Tliere shall be no floating solids, scttlcable solids, oil or sludge deposits attributable to 

 sewage, industrial wastes or other wastes and no deposit of 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, solids, color, turbidity, taste, odor or toxic nuterial, such that these treated 

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

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

 consumption. 



Tlierc shall be no toxic wastes, deleterious substances, colored or other wastes or heated 

 liquids discharged to waters of this cbssification, either singly or in combination 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 propagation thereof, or which in any manner shall 

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

 sufficient amounts to make the waters unsafe or unsuitable for bathing or impair the waters 

 for any other best usage as determined for the specific waters which arc assigned to this 

 class. There shall be no waste discharge which will cause the hydrogen-ion concentiation or 

 "pll" of these waters to fall outside the 6.7 to 8.5 range. Tlierc shall be no disposal of 

 matter or substance that contains chemical constituents which are harmful to humans, 

 animal or aquatic life or which adversely affects any other water use in this class. No 

 radioactive matter or substance sliall be permitted in these waters which would be harmful 

 to humans, animal or aquatic life and there shall be no disposal of any matter or substance 

 which would result in radio-nuclide concentrations in edible fish or other aquatic life thereby 

 rendering them dangerous for human consumption. These waters shall be free of any matter 

 or substance which alters the composition of bottom fauna, which adversely affects the 



physical or chemical nature of bottom material or which interferes with the propagation of 

 fish or shellfish if indigenous to the area. 



Class SB-2 shall be suitable for recreational usages, including water contact, and fishing. 

 Such waters shall be suitable for the harvesting and propagation of shellfish, for a fish and 

 wildlife habitat, and suitable for industrial cooling and process uses. Iliese waters shall 

 contain not less than 6.0 parts per miUion of dissolved oxygen at all times. The median 

 numbers of coliform bacteria in any series of samples representative of waters in the shellfish 

 growing area shall not be in excess of 70 per 100 milliliters, nor shall more than 10% of the 

 samples exceed 230 coliform bacteria per 100 milhliters. The median numbers of fecal 

 coliform bacteria in any series of samples representative of waters in the shellfish growing
