No person shall discharge or cause to be discharged, directly or indirectly, any of the following substances into any of the sewers or wastewater treatment plant under the control of or ownership of the City Wastewater Department.
(a) Any storm water, roof run-off, surface water such as from basement step drains, catch basins, and other devices used to catch and control surface water, ground water, or other subsurface drainage or unpolluted industrial process water or noncontact cooling water. The only exception to this rule shall be those accounts currently served by existing combined sewers.
(b) Any solids, liquids or gases which by reason of their nature or quantity are or may be sufficient either alone or by interaction with other substances to cause fire or explosion or be injurious in any way to the treatment plant or operation thereof; at no time shall two consecutive readings on an explosion hazard meter at the point of discharge into the system, or at any point in the system, be more than five percent (5%) nor any single reading over ten percent (10%) of the lower explosion
limit of the meter. Prohibited materials include but are not limited to the following: gasoline, kerosene, naphtha, benzene, fuel oil, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides or any other substances which the City, State or U.S. E.P.A. has notified the system user is a fire or explosion hazard to the sewerage system.
(c) Any solid or viscous substances in quantities or of such size which may cause obstruction to the flow in a sewer or other interferences with the operation of the wastewater treatment plant including, but not limited to, the following: grease, animal intestines or tissue, paunch manure, bones, hair, hides or fleshings, entrails, blood, feathers, ashes, cinders, sand, mud, spent lime, stone or marble dust, wood, metal, glass, plastics, shavings, straw, grass clippings, rags, spent grains, waste paper, paper products, tar, asphalt residues, residues from the refining or processing of fuel or lubricating oils or lens grinding or polishing wastes.
(d) Any garbage, except that which originates from dwellings and has been properly shredded (see Section 925.02
(a)(53) for the definition of shredded garbage). Garbage grinders may not be connected to the public sanitary sewers from hotels, institutions, restaurants, hospitals, groceries, catering establishments or similar place where garbage originates from the large scale preparation of food for sale or consumption on the premises or for carry-out by customers.
(Ord. 90-1343. Passed 11-6-90.)
(e) Any water or waste containing more than ten mg/l of petroleum oil, nonbiodegradable cutting oils, products of mineral oil origin or floatable oils, fats, wax or grease. (Ord. 2000-46. Passed 8-1-00.)
(f) Any water or waste having a pH less than 6.0 standard units or greater than 9.6 standard units or having any corrosive property capable of causing damage or hazard to structures, equipment or operating personnel of the treatment facility (see Section 925.02
(a)(39) for the definition for pH).
(Ord. 90-1343. Passed 11-6-90.)
(g) Any water or waste containing toxic pollutants in sufficient quantity either alone or by interaction with other substances to injure or interfere with any treatment process, constitute a hazard to humans or animals, create a public nuisance, create a toxic effect in the receiving stream of the wastewater treatment plant or exceed any limitations set forth in a Categorical Pretreatment Standard or any pollutant identified as toxic pursuant to Section 307 of the Clean Water Act, to include but not limited to: arsenic, cadmium, chromium, hexavalent chromium, copper, cyanide, lead, mercury, nickel, phenol, phthalate esters, silver and zinc.
(Ord. 91-1397. Passed 8-20-91.)
(h) Any noxious or malodorous solids, liquids or gases which either alone or by interaction with other substances are sufficient to create a public nuisance or hazard to human life or are sufficient to prevent entry into the sewer manholes for maintenance or repair of the collection system or treatment unit.
(i) Any water or waste which may cause a wastewater treatment plant's effluent (treated water leaving plant) or any other product of the plant such as residues, sludges and scums to be unsuitable for reclamation or to interfere with the reclamation process. In no case shall a substance discharged to the sewerage system cause that system to be in noncompliance with sludge use or disposal criteria, guidelines or regulations as developed under Section 405 of the Clean Water Act, Solid Waste Disposal Act, Clean Air Act, Toxic Substances Control Act or any Ohio EPA criteria applicable to sludge management.
(j) Any water or waste that shall cause the wastewater treatment plant to violate its NPDES permit.
(k) Any water or waste with objectionable color not removed in the treatment process such as, but not limited to, dye wastes and vegetable tanning solutions.
(l) Any water or waste having a temperature which shall inhibit biological activity in the treatment plant resulting in interference with the plant's treatment efficiency. In no case shall any wastewaters exceeding 120 degrees Fahrenheit (forty-nine degrees Centigrade) or which would cause the wastewaters at the treatment plant to exceed 104 degrees Fahrenheit (forty degrees Centigrade) be discharged into the sewerage system.
(m) Any water or waste containing radioactive wastes or isotopes of such half-life or concentrations as may exceed limits established by the Director of the Wastewater Department in compliance with applicable State or Federal regulations.
(n) Any water or waste which are not amenable or which are only partially amenable to treatment or reduction by the wastewater treatment plant and which would cause such plant to violates its NPDES permit or to violate applicable water quality standards in the receiving stream.
(o) Any water or waste containing compatible pollutants which by reason of their concentration could not be adequately treated at the wastewater treatment plant.
