with discharges by other sources, inhibits or disrupts the POTW, its
treatment processes or operations, or its sludge processes, use or
disposal and which is a cause of a violation of any requirement of
the POTW's NPDES permit (including an increase in the magnitude or
duration of a violation) or of the prevention of sewage sludge disposal

into a watercourse, pond, ditch, lake, or other body of surface water
or groundwater.
PASS-THROUGH
The discharge of pollutants through the public owned treatment
works (POTW) into navigable waters in quantities or concentrations
which, alone or in conjunction with discharges from other sources,
