(B) No user shall contribute or cause to be contributed into the POTW, directly or indirectly, any pollutant or wastewater that causes interference or pass-through. These general prohibitions apply to all users of a POTW, whether or not the user is a significant industrial user or subject to any national, state or local pretreatment standards or requirements.
(C) It shall be unlawful for any person to discharge, or cause to be discharged, into any sanitary sewer any stormwater, surface water, groundwater, roof runoff, subsurface drainage or other unpolluted water.

(F) Pollutants, substances, wastewater or other wastes prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the municipal wastewater system.
