Except as hereinafter provided, no persons shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:
(A) Storm, surface and ground water; prohibited connections:
(1) No ground, surface or other water from any inflow source shall be discharged into any sanitary sewer;
(2) No downspout shall be connected to any combined sewer or sanitary sewer any such connections that currently exist shall be removed to prevent such flows from entering into any sanitary sewer;
(3) The construction of new combined sewers is prohibited;
(4) If a separate storm sewer becomes available within a combined sewer area, all clear water sources shall be disconnected form the combined sewer;
(5) No storm water, surface water, ground water, runoff water, footing tiles, subsurface drainage, cooling water or unpolluted industrial processed water shall be discharged into any sanitary sewer;
(6) Storm water and all other unpolluted drainage shall be discharged to such sewers specifically designated as storm sewers or to a natural outlet approved by the town;
(7) Industrial cooling water or unpolluted processed waters may be discharged, upon prior approval by the town and the issuance of a permit, to a storm sewer or natural outlet. If such permit is granted for discharge the user shall pay the applicable use and connection charges and fees and shall meet such other conditions as required by the town in said permit; and
(8) In any new building the inflow/clear water connection to a combined sewer shall be made separate and distinct from sanitary waste connection to facilitate disconnection of the former if separate storm sewer subsequently becomes available.
(B) Any liquid or vapor having a temperature higher than 150° F. (65° C.).
(C) Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32° F. and 150° F.
(D) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor greater than 3/4 horsepower (0.75 hp metric) shall be subject to the review and approval of the town. Garbage grinders shall not be used for grinding plastic, paper products, inert material or garden refuse.
(E) Wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the town for such materials.
(F) (1) Any waters or wastes containing in excess of:
0.2 mg/l cadmium
2. mg/l copper
2 mg/l cyanide
2 mg/l lead
2 mg/l nickel
2 mg/l total chromium
4 mg/l zinc
1.0 mg/l mercury
2 mg/l silver
1 mg/l phenolic compounds
0.02 mg/l total identifiable chlorinated hydrocarbons
(2) All other parameters to be limited in amounts set forth in the proposed pretreatment guidelines issued by USEPA, dated October 1975.
(G) Any radioactive wastes or isotopes of such halflife or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations.
(H) Any waters or wastes having a pH in excess of 9.0 or lower than 6.0.
(I) Materials which exert or cause:
(1) Unusual concentrations of inert, suspended solids (such as but not limited to Fullers earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate).
(2) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).
(3) Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
(4) A fire or explosion and/or damage to life or safety of personnel.
(5) A nuisance or obstruction of flow in a sewer system or injury of the system or damage to the wastewater collection, treatment of disposal facilities.
(6) Air pollution and/or a strong unpleasant odor by release of toxic or malodorous gases or malodorous gas producing substances.
(J) Waters or wastes containing substances which cannot be treated or reduced by the sewage treatment processes employed, or may be treated only to such a degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
(K) Any waste, which cause, threaten to cause, or are capable of causing either alone or by interaction with other substances, the wastewater treatment plant's effluent or any other product of the treatment process, residues, sludges, or scum, to be unsuitable for reclamation, disposal, or reuse or to interfere with the reclamation process, or to fail to meet any of the limitations set by any federal or state agency or the terms of the towns's NPDES permit.
(L) Quantities or rates of flow which overload the town's collection or treatment facilities or cause excessive town collection or treatment costs, or may use a disproportionate share of the town facility.
