§ 53.084 MATERIALS AND SUBSTANCES EXCLUDED FROM PUBLIC SEWERS.
   (A)   Except as hereinafter provided, no person shall discharge or cause to be discharged, or allow to run, leak, or escape into any public sewer, pipe, channel or sewer appurtenance connecting with any public sewer, or into any private sewer connected with a public sewer, any of the following described materials, substances or wastes except such small quantities as may be present in normal household wastes:
      (1)   Construction materials, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, paunch manure, coffee grounds, fur, wax or any solids or viscous substances capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewer system;
      (2)   Dumping of snow and ice into public sewers;
      (3)   Any gasoline, benzine, naphtha, fuel oil or other inflammable or explosive liquids, solids or gases;
      (4)   Steam or hot water above 150°F (65.6°C);
      (5)   Any waste or water which may contain petroleum hydrocarbons, such as greases, oil and oil sludges from garages, repair shops, machine shops, industrial establishments in concentrations in excess of 100 milligram per liter. However, fats and greases, such as those derived from cooking and food processing, may be discharged to borough sewers, provided that the concentration and physical dispersion of the fats and greases does not result in separation and the adherence to sewer structures or appurtenances. If there is evidence of adherence of such materials to said structures, or if such materials cause blockage in the sewer system, then the wastewater carrying such materials must be effectively treated by a process or device, such as a grease trap or interceptor, before its discharge to borough sewers;
      (6)   Coal tar, its derivatives and waste;
      (7)   Any waters or wastes having a pH lower than 6.0 or higher than 9.0 or having any other corrosive property apt to cause damage or hazard to structures, equipment of the sewer system or personnel employed in its operations;
      (8)   Any liquids or wastes containing toxic or poisonous substances in sufficient quantity or rate of flow as to injure or interfere with any of the sewage treatment processes to constitute a hazard to human beings or animals, or to create any hazard in the receiving waters;
      (9)   Any liquids or wastes containing suspended solids of such quality and/or quantity that become burdensome in the operation and maintenance of the sewage treatment plant facilities;
      (10)   Any noxious or malodorous gas or substance capable of creating a public nuisance;
      (11)   Any natural waters, including lake and swamp drainage, or recycled stream waters; and
      (12)   Any water or substance, which in the opinion of the borough will result in a discoloration or other undesirable physical change in the appearance of the stream receiving the discharge from the borough’s sewage treatment plant.
   (B)   When in the opinion of the borough the solids in an industrial or commercial waste require comminution before discharge to the sewer system, not only must the necessary comminution facilities be approved for adequacy, but also the operating results must satisfactorily abate the problem which such solids may tend to create in the sewer system.
   (C)   Any physical connection to a public sewer, or to a private sewer connected to a public sewer, from vessels, tanks or containers receiving any of the hereinbefore mentioned materials and substances from which quantities of the aforesaid prohibited materials or substances could accidentally be discharged directly or indirectly into the public sewers is prohibited. Precautions shall be taken to prevent the accidental spillage of any of the hereinbefore mentioned material to floor drains, basins, manholes, gutters and the like, from any manufacturing process or storage tank.
