(A) No person shall discharge or cause to be discharged any stormwater, groundwater, roof runoff, subsurface drainage, down spouts, yard drains, yard fountains and ponds or lawn sprays into any sanitary sewer.
(1) Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the approving authority.
(2) Unpolluted processed water may be discharged upon prior written approval of the approving authority to a storm sewer or natural outlet or into the sanitary sewer system by and in direct connection whereby such discharge is cooled, if required, and flows into the sanitary sewer at a rate not in excess of three gallons per minute, provided that the waste does not contain materials or substances in suspension or solution in violation of the limits prescribed by this subchapter.
(3) Any person discharging waste of any type into a storm sewer or natural outlet shall first obtain the written permission of the approving authority who shall designate the point of discharge whether it be sanitary sewer, storm sewer or natural outlet.
(4) In cases where, and in the opinion of the approving authority, the character of the sewage from any manufacturer or industrial plant building or other premises is such that it will damage the system or cannot be treated satisfactorily in the system, the approving authority shall have the right to require such user to dispose of such waste otherwise and prevent it from entering the system.
(B) No person shall discharge or cause to be discharged, either directly or indirectly, any of the following described substances, materials, waters or waste:
(1) Any liquid having a temperature higher than 150°F (65°C);
(2) Any water or wastes which contain wax, grease or oil, plastic or other substance that will solidify or become discernibly viscous at temperatures between 32°F to 150°F;
(3) Any solids, liquids or gases which by themselves or by interaction with other substances may cause fire or explosion hazards or in any other way be injurious to persons, property or the operation of the sewage works;
(4) Any solids, slurries or viscous substances of such character as to be capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works, such as but not limited to ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, whole blood, paunch manure, hair and fleshings, entrails, lime slurry, lime residues, slops, chemical residues, paint residues or bulk solids;
(5) Any garbage that has not been properly comminuted or shredded;
(6) Any noxious or malodorous substance which, singly or by interaction with other substances, is capable of causing objectionable odors or hazard to life; or forms solids or creates any other condition deleterious to structures or treatment processes; or requires unusual provisions, alteration or expense to handle such material;
(7) Any waters or wastes having a pH lower than 5.5 or higher than 10.5 point or having any corrosive property capable of causing damage or hazards to structures, equipment, personnel or biological population of the sewage works;
(8) Any waters or wastes containing suspended or dissolved solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment or in the public sewage works;
(9) Any waters or wastes containing a toxic or poisonous substance, such as but not limited to plating or that treating wastes in sufficient quantity to injure or interfere with any sewage treatment process, to constitute a hazard to humans or animals or to create any hazard in the receiving waters or the sewage treatment plant;
(10) Any cyanide greater than 1.0 part per million;
(11) Any hexavalent chromium greater than 2.0 parts per million;
(12) Any mercury greater than 0.005 part per million;
(13) Any trivalent chromium greater than 5.0 parts per million;
(14) Any manganese greater than 1.0 part per million;
(15) Any copper greater than 1.0 part per million;
(16) Any boron greater than 1.0 part per million;
(17) Any nickel greater than 1.0 part per million;
(18) Any cadmium greater than 0.02 part per million;
(19) Any arsenic greater than 0.05 part per million;
(20) Any zinc greater than 1.0 part per million;
(21) Any phenols greater than 0.2 part per million;
(22) Any iron greater than 2.0 parts per million;
(23) Any tin greater than 1.0 part per million;
(24) Any barium greater than 5.0 parts per million;
(25) Any lead greater than 0.1 part per million;
(26) Any silver greater than 0.10 part per million;
(27) Any selenium greater than 0.02 part per million;
(28) Any chlorides greater than 250.0 parts per million;
(29) Any radioactivity as radium maximum contaminant level 226 of 3 pci/l and strontium 100 pci/l.7;
(30) Any antimony greater than 0.0 part per million;
(31) Any beryllium greater than 0.0 part per million;
(32) Any bismuth greater than 0.0 part per million;
(33) Any cobalt greater than 0.0 part per million;
(34) Any molybdenum greater than 0.0 part per million;
(35) An rhenium greater than 0.0 part per million;
(36) Any tellurium greater than 0.0 part per million; or
(37) Any uranylion greater than 0.0 parts per million.
(C) Except in quantities or concentrations or with provisions as stipulated herein, it shall be unlawful for any person to discharge waters or wastes to the sanitary sewer containing the following:
(1) Free or emulsified oil and grease exceeding on analysis an average of 100 parts per million 833 pounds per million gallons of either or both or combinations of free or emulsified oil and grease, if, in the opinion of the approving authority it appears probable that such wastes:
(a) May deposit grease or oil in the sewer lines in such a manner to clot the sewers;
(b) May overload slamming and grease-handling equipment;
(c) Are not amenable to bacterial action and will therefore pass to the receiving waters without being affected by normal sewage treatment processes; and
(d) May have deleterious effects on the treatment process due to the excessive quantities.
(2) Any radioactive wastes greater than the allowable stipulated above;
(3) Cyanides or cyanogen compounds capable of liberating hydrocyanic gas on acidification in excess of 0.5 part per million by weight as CN in the wastes from any outlet into the public sewers; and
(4) Material which exert or cause the following:
(a) Unusual concentrations of solids or composition as, for example, in total suspended solids or inert nature (such as Fuller’s earth) or in total-dissolved solids (such as sodium chloride or sodium sulfate);
(b) Excessive discoloration;
(c) Unusual biochemical oxygen demand;
(d) High hydrogen sulfide content; and
(e) Unusual flow and concentration, unless such material shall be pretreated to a concentration acceptable to the town, if such wastes can cause damage to collection facilities, impair the processes, incur treatment costs exceeding those of normal sewage or render the water unfit for stream disposal. Where discharge of such wastes to the sanitary sewer are not property pretreated or otherwise corrected, the approving authority shall reject the wastes or terminate the service of water or sanitary sewer.
