No person shall discharge or cause to be discharged any storm water, surface water, ground water, roof runoff, subsurface drainage, cooling water or unpolluted industrial process waters to any sanitary sewer located within the city, or within any area under the jurisdiction of the city, unless such discharge is approved in writing by the Service Director.
Storm water 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 Service Director. Industrial cooling water or unpolluted process waters may be discharged, upon approval of the Service Director, to a storm sewer, combined sewer or natural outlet.
No discharger shall contribute or cause to be discharged, directly or indirectly, any of the following described substances into the wastewater disposal system or otherwise to the facilities of the city:
(A) Any gasoline, benzene, naphtha, fuel oil, mineral oil or other liquids, solids or gases which by reason of their nature or quantity are, or may be sufficient either alone or by interaction to cause fire or explosion or be injurious in any other way to the operation of any wastewater treatment plant or constitute a hazard to humans or animals.
(B) Any water or waste which contains grease, fats, wax or oil or other substances that will solidify or become discernably viscous at temperatures between thirty-two degrees and 150 degrees Fahrenheit.
(C) Any wastewater having a pH less than 6.0 or higher than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel of the system.
(D) Any noxious or malodorous liquids, gases, or solids which either singly or by interaction are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair.
(E) Any substance which may cause the wastewater treatment plant's effluent or treatment residues, sludges or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance discharged to the sewer system cause the wastewater treatment plant to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act; any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, or State standards applicable to the sludge management method being used.
(F) Any substance which will cause the treatment works to violate its NPDES and/or other disposal system permits or which otherwise interferes with the treatment works.
(G) Any substance with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.
(H) Any wastewater having a temperature which will inhibit biological activity in the wastewater treatment plant resulting in interference; but in no case, wastewater with a temperature at the introduction into the treatment works which exceeds 104 degrees Fahrenheit.
(I) Any slugload, which means any substance released in a discharge at a rate and/or concentration which causes interference to a POTW.
(J) Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as exceed limits established by the city in compliance with applicable State or Federal regulations.
(K) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower or larger shall be subject to the review and approval of the Service Director.
(L) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure, hair and fleshings, entrails, lime slurry, lime residues, beer or distillery slops, chemical residues, paint residues, cannery waste bulk solids, or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works.
