 saturation, and not less than 5 parts per million at any time Tlie fecal colHbrin bacteria is not 

 to exceed 2(ltl pet 1110 millilieters 



1977, c. 373, §4. 



Ihcse waters shall be free from sludge deposits, solid refuse and tloating solids such as 

 oils, grexse and scum. 11iere shall be no disposal of any mailer or substance in these waters 

 which imparts color, turbidity, taste or odor which would impair the usages ascribed to litis 

 classification, nor shall such matter or substance alter the temperature or hydrogen-ion 

 concentration of the waters so as to render such waters harmful to fish or other aquatic life, 

 'riierc shall be no disposal of any nutter or substance that contains chemical constituents 

 which are harmful to humans, animal or aquatic life, or which adversely affect any other 

 water use in this class, llierc shall be no discharge to these waters which will cause the 

 hydrogen-ion concentration of "pH" of these waters to fall outside of the 6.0 to 8.S range. 

 No radioactive nialtcr or substance shall be discharged to these waters which will raise the 

 radio-nuclid concentrations above Ihe standards as established by the United States Public 

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

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

 the physical or cheniicul nature of bottom material, or which interferes with the propagation 

 of fish. 



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

 except those which have received treatment lor the adequate removal of waste constituents 

 including, but not limited to, solids, color, turbidity, taste, odor or toxic material, such that 

 these treated wastes will not lower the standards or alter the usages of this classificalion, nor 

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

 for huiiun consumption. 



Class C. waters, The 3rd highest classification, shall be of such quality as to be 

 satisfactory lor recreaticmal boating and fishing, for a fish and wildlife habitat and for other 

 uses except potable water supplies and water contact recreation, unless such waters are 

 adequately treated. 



11ic dissolved oxygen content of such waters shall no! be less than S parts per million, 

 except in tho.se cases where the board finds that the natural dissolved oxygen of any such body 

 of water falls Ik-Iow 5 parts per million, in which case the board may grant a variance to this 

 re(|uireiiient In no event shall the dis.solved oxygen content of such waters be less than 4 parts 

 |x:r million. The fecal ooliforin bacteria is not to exceed 1,000 per 100 milliliters. 



1973, c. 423. S 5; 1977, c. 373, § 5. 



These waters shall be free from sludge deposits, solid refuse and floating solids such as 

 oils, grease or scum, lliere shall be no disposal of any nutter or substance in these waters 

 which imparts color, turbidity, taste, or odor which would impair the usages ascribed to this 

 classification, nor shall such nutter or substance alter the temperature or hydrogen-ion 

 content of the waters so as to render such waters harmful to fish or other aquatic life. There 

 shall be no discharge to these waters which will cause the hydrogen-ion concentration or 

 "pi I" of these waters to fall outside of the 6.0 to 8.S range. There shall be no disposal of 

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

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

 radioactive material or substance shall be discharged to these waters which will raise the 

 radio-nuclide concentration above the standards as established by the United States Public

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 or toxic material, such that 

 these treated wastes will not lower Ihe standards or alter Ihe usages of this classification, 

 nor shall such disposal of sew.igc or waste be injurious to aquatic life or render such
