No person shall allow, or cause to allow, stormwater discharges
into any stormwater collection system within the Township which are
not composed entirely of stormwater, except discharges allowed under
a state or federal permit or as set forth below.
When it is more advantageous to connect directly to streets or storm
sewers, connections of roof drains to streets or roadside ditches
may be permitted on a case-by-case basis by the Township, upon recommendation
of the Township Engineer.
