If a person who is not an industrial user contemplates
a modification to the use of an existing sanitary sewer such that
the user intends to introduce industrial wastes or discharge more
than the equivalent of twenty-five thousand (25,000) gallons per day
of sanitary waste, a sewer connection application shall be submitted
to the PVSC and, if required, a permit issued prior to the commencement
of the discharge. The discharge of industrial or sanitary wastes without
a sewer connection permit, as stated in this section, constitutes
a violation of these Rules and Regulations.
