§ 52.23  PROHIBITED DISCHARGES.
   (A)   (1)   It shall be unlawful for any person to discharge or cause to be discharged any pollutant or wastewater which will interfere with the operation and/or performance of the POTW.
      (2)   These general prohibitions apply to all such users of the POTW whether or not the user is subject to pretreatment standards or any other federal, state or local government limitations or requirements.
   (B)   A user shall not discharge the following substances to the POTW:
      (1)   Any unpolluted waters such as infiltration/ inflow to any sanitary sewer. Storm water and all other unpolluted drainage shall be discharged to such sewers as are specifically designed as storm sewers or to a natural outlet approved by the Director and the DEM. Unpolluted cooling water or process waters may be discharged on approval of the DEM to a storm sewer or natural outlet. Under unusual circumstances or where a natural outlet is not available, the local government may allow the discharge of unpolluted cooling water to the wastewater disposal system;
      (2)   Any liquids, solids 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 other way to the POTW or to the operation of the POTW. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the system, or at any point in the system, be more than 5%, nor any single reading over 10%, of the lower explosive limit (LEL) of the meter. Materials specifically prohibited from discharge into the POTW include gasoline, kerosene, naphtha, fuel oil, and any other substance which the local government, the state or the EPA has notified the user is a fire hazard or a hazard to the system;
      (3)   Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the POTW, such as, but not limited to: floatable oil; garbage with articles greater than one-half inch in any dimension; animal guts, scales or tissues; paunch manure; bones, hair, hides or fleshing; entrails; whole blood; feathers; ashes; cinders; sand; spent lime; stone or marble dust; metal glass; straw; shavings; grass clippings; rags; spent grains; spent hops; wastepaper; wood; plastics; gas; tar; asphalt residues; residues from refining or processing of fuel or lubricating oil; mud; or glass grinding or polishing wastes;
      (4)   Any wastewater having a pH less than 5.0 or greater and/or wastewater having any other corrosive property capable of causing damage or hazard to the waste water disposal system or local government personnel;
      (5)   Any wastewater containing toxic substance or other pollutants in sufficient quantity, either singly or by interaction with other pollutants, which will cause interference, constitute a hazard to humans or animals, or create a toxic effect in the receiving waters of the POTW;
      (6)   Any noxious or malodorous liquids, gases or solids which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sanitary sewer for maintenance and repair;
      (7)   Any substance which may cause the POTWs effluent or any other product to be unsuitable for reclamation and reuse. In no case shall a substance discharge to the POTW cause the POTW to fail to be in compliance with sludge use or disposal criteria, guidelines or regulations developed under § 405 of the Act, being 33 U.S.C. § 1345, or any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, being 42 U.S.C. §§ 6901 et seq., the Clean Act, being 42 U.S.C. §§ 7401 et seq., the Toxic Substances Control Act, being 15 U.S.C. §§ 2601 et seq., or state criteria applicable to the sludge management method being used;
      (8)   Any wastewater with color, such as, but not limited to, ink, paints, dye wastes and vegetable tanning solutions which cause interference or prevent the POTW from complying with local, state or federal effluent limitations or water quality standards;
      (9)   Any wastewater, liquid or vapors having a temperature higher than 140°F;
      (10)   Any waste containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the local government in compliance with applicable state and/or federal regulations; and
      (11)   Quantities of flow, concentrations or both which constitute a “slug”, as defined herein.
