No person shall discharge, or cause to be discharged, any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters except groundwater remediation water to any sanitary sewer. (Ord. 1268, 12-5-1989; amd. Ord. 1454, 3-7-1995)
(A) Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers, or to a natural outlet approved by the wastewater treatment superintendent. Industrial cooling water or unpolluted process waters may be discharged on written approval of the wastewater treatment superintendent, to a storm sewer, combined sewer, or natural outlet.
(B) Owners of all other wastewater collection systems, whether public or private, with combined sewers tributary to Canton's wastewater collection system shall have procedures in place prior to the discharge of any material to Canton's system, which shall be approved by the wastewater treatment superintendent to ensure that the following items are achieved consistent with federal, state and local standards:
1. Inspect the collection system on a regularly scheduled basis.
2. Clean and maintain sewers, catch basins and regulators on a regularly scheduled basis.
3. Inspect and perform preventative maintenance on all lift stations.
4. Repair collection system problems in a timely manner. Replace sewers where necessary.
5. Detect and eliminate illegal connections.
6. Detect, prevent, and eliminate dry weather overflows.
7. Operate the collection system to maximize storage capacity. Operate the combined sewer portions of the collection systems to delay the entry of storm flow into the system.
8. Operate the treatment and collection systems to maximize treatment. (Ord. 2073, 2-7-2012)
No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(A) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas. Remediation waters from leaking underground storage tanks or surface spills may be allowed provided that the same do not exceed the limits of subsection 8-19-31(M) of this chapter.
(B) Any waters or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the sewage treatment plant.
(C) Any waters or wastes having a pH lower than five and five- tenths (5.5) or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewage works.
(D) Solid or viscous substances in quantities or of such size 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, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders. (Ord. 1268, 12-5-1989; amd. Ord. 1454, 3-7-1995)
No person shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appears likely in the opinion of the wastewater treatment superintendent that such wastes can harm either the sewers, sewage treatment process or equipment; have an adverse effect on the receiving stream; or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the wastewater treatment superintendent will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and maximum limits established by regulatory agencies. The substances prohibited are:
(A) Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150°F) (60°C).
(B) Any waters or wastes containing toxic or poisonous material; or oils, whether emulsified or not, in excess or one hundred milligrams per liter (100 mg/l) or containing substances which may solidify or become viscous at temperatures between thirty two degrees (32°) and one hundred fifty degrees Fahrenheit (150°F) (0° and 65°C).
(C) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (3/4) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the wastewater treatment superintendent.
(D) Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solution, whether neutralized or not.
(E) Any waters or wastes containing iron, chromium, copper, zinc, or similar objectionable or toxic substances; or 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 wastewater treatment superintendent for such materials.
(F) Any waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the wastewater treatment superintendent as necessary after treatment of the composite sewage, to meet the requirements of the state, federal, or other public agencies of jurisdiction for such discharge to the receiving waters.
(G) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the wastewater treatment superintendent in compliance with applicable state or federal regulations.
(H) Any wastes or waters having a pH in excess of nine and five-tenths (9.5).
(I) Any mercury or any of its compounds in excess of 0.0005 mg/l as Hg at any time except as permitted by the wastewater treatment superintendent in compliance with applicable state and federal regulations.
(J) Any cyanide in excess of 0.025 mg/l at any time except as permitted by the wastewater treatment superintendent in compliance with applicable state and federal regulations.
(K) Materials which exert or cause:
1. Unusual concentrations of inert suspended solids (such as, but not limited to, fuller's 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 waste 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. Unusual volume of flow or concentrations of wastes constituting "slugs" as defined herein.
(L) Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters. (Ord. 1268, 12-5-1989)
(M) Any ground water or surface water which is collected in an effort to remediate ground water which has been contaminated with petroleum hydrocarbons which will exceed the following limitations:
