No user shall discharge or deposit any of the following materials, waste materials, waste gases or liquids into any sanitary sewer forming part of the County sewerage system:

  1. 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 way to the County sewerage system or to the operation of the County sewerage system. At no time shall 2 successive readings (15 to 30 minutes between readings) on an explosion hazard meter at point of discharge into the County sewerage system be more than 5% nor any single reading be more than 10% of the lower explosive limit (LEL) of the meter.

  3. Any substances which may cause wastewater treatment plant effluent or any other products of the County sewerage system, such as residues, sludges, or scum, to be unsuitable for the reclamation process. In no case shall a substance discharged into the County sewerage system cause the system to be in noncompliance with sludge use or disposal criteria, guidelines, ordinance, or regulations developed by local, state or federal authorities.
  4. Any substance which will cause the County sewerage system to violate its NPDES permit or the receiving water quality standards established by the DEM, the EPA or any other governmental entity having jurisdiction.
  5. Any water or wastes which, by interaction with other waters or wastes in the County sewerage system, release obnoxious gases, form suspended solids which interfere with operation of the sanitary sewers or create conditions deleterious to structures and treatment processes.
  6. Any form of inflow, as defined by §94-3, including storm drainage.
  7. Infiltration, as defined by §94-3, in excess of 300 gallons per inch of pipe diameter per mile of pipe per day.
