915.07 PROHIBITED DISCHARGE(S) TO THE POTW.
   (a)   General Prohibitions. No User shall introduce or cause to be introduced into the POTW any Pollutant or Wastewater which causes Pass Through or Interference. These general prohibitions apply to all Users of the City's POTW whether or not they are subject to categorical Pretreatment Standards or any other National, State, or local Pretreatment Standards or Requirements.
   (b)   Specific Prohibitions. No User shall introduce or cause to be introduced into the POTW the following Pollutants, substances, or Wastewater:
      (1)   Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, waste streams with a closed cup flashpoint of less than 140 degrees F (60 degrees C) using the test methods specified in 40 CFR 261.21;
      (2)    Wastewater having a pH less than 5.0 or more than11.0, or otherwise causing structural damage to the POTW or equipment;
      (3)   Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in Interference but in no case solids greater than ¾ inch in any dimension, such as, but not limited to: ashes, bones, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, un-ground garbage, whole blood, paunch manure, hair and fleshings, entrails, and paper dishes, cups and milk containers, either whole or ground by garbage grinders as determined by the Director;
      (4)   Pollutants, including oxygen demanding Pollutants (BOD, etc.), released in a Discharge at a flow rate and/or Pollutant concentration which, either singly or by interaction with other Pollutants, will cause Interference or Pass Through with the POTW;
      (5)   Wastewater Discharge having a temperature greater than 104 degrees F (40 degrees C).
      (6)   Toxic wastes. Wastewaters containing or which result in the presence of toxic or poisonous solids, liquids, gases, vapors or fumes within the POTW in sufficient quantity, either singly or in combination with other wastes, to injure or interfere with any waste treatment process, render treatment process effluents or residues unfit for reclamation or reuse, cause violations of the NPDES Discharge permit or other disposal system permits, constitute an acute health hazard or safety problem to humans or animals, create a public nuisance or create any hazard or water quality violation in the receiving waters of the WRF;
      (7)   Trucked or hauled Pollutants, except at discharge points designated and approved by Director;
      (8)   Noxious or malodorous liquids, gases, solids, or other Wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life, or that prevents entry into the sewers for maintenance or repair;
      (9)   Wastewater which imparts color which cannot be removed by the WRF, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently impart color to WRF effluent, thereby violating the City's NPDES permit;
      (10)   Wastewater containing any radioactive wastes or isotopes except in compliance with applicable State or Federal regulations;
      (11)   Storm Water, surface water, ground water, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, de-ionized water, Noncontact Cooling Water, and unpolluted Wastewater, unless specifically authorized by Director;
      (12)   Sludges, screenings, or other residues from the Pretreatment of industrial wastes;
      (13)   Medical Wastes, except as specifically authorized by Director in an WDP;
      (14)   Wastewater causing, alone or in conjunction with other sources, the WRF effluent to fail toxicity test;
      (15)   Detergents, surface active agents, or other substances which might cause excessive foaming in the POTW;
      (16)   Wastewater causing two readings on an explosion hazard meter at the point of discharge into the POTW, or at any point in the POTW, of more than ten percent (10%), or any single reading over ten percent (10%), of the Lower Explosive Limit of the meter.
      (17)   Any garbage which has not been properly shredded as defined herein. The installation of any garbage grinder equipped with a motor greater than three fourths (3/4) horsepower shall require the prior written approval of the Director.
      (18)   Limitations on point of discharge. No Person shall Discharge any substances including trucked or hauled Pollutants such as industrial and Holding Tank Waste directly into a manhole or other opening in a public Sanitary Sewer or the POTW, unless that Person has been issued a WDP which specifies locations and times of discharge designated by the Director. If a permit is issued for such Discharge, the Person shall pay the applicable charges and fees and shall meet such other conditions as required by the Director.
      (19)   Any removal of manhole covers or other access to the POTW for the purpose of discharging wastes at times and/or locations other than those designated by the Director, or without the Director's expressed permission, shall be a violation of this chapter, and shall subject the User to enforcement actions including fines and penalties contained herein.
      (20)   Quantities of flow, concentrations or both which constitute Slug Load or Slug Discharge as defined herein.
      (21)   Non-polar FOG shall not be discharged at a concentration in excess of limits in 915.11(b) (2).
      (22)   Discharge of Wastewater containing Polar FOG as prohibited under section 915.08 (FOG Standards). Pollutants, substances, or Wastewater prohibited by this Section shall not be processed or stored in such a manner that they could be discharged to the POTW.
