No person in the municipality shall allow or cause to allow stormwater discharges into the municipality's separate storm sewer system which are not composed entirely of stormwater except as provided in Subsection B below or as allowed under a state or federal permit.
Discharges that may be allowed based on the municipality finding
that the discharge(s) does not significantly contribute pollution
to surface waters of the commonwealth are listed below.
Pavement washwaters where spills or leaks of toxic or hazardous
materials have not occurred (unless all spill material has been removed)
and where detergents are not used.
In the event that the municipality determines that any of the discharges identified in § 139-36B significantly contribute to pollution of waters of the commonwealth or is so notified by DEP, the municipality will notify the responsible person to cease the discharge.
Upon notice provided by the municipality under § 139-36C, the discharger will have a reasonable time, as determined by the municipality, to cease the discharge consistent with the degree of pollution caused by the discharge.
Any drain or conveyance, whether on the surface or subsurface, which
allows any nonstormwater discharge including sewage, process wastewater
and wash water to enter the separate storm sewer system and any connections
to the storm drain system from indoor drains and sinks.
Any drain or conveyance connected from a commercial or industrial
land use to the separate storm sewer system which has not been documented
in plans, maps or equivalent records and approved by the municipality.
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 by the municipality.
No person shall modify, remove, fill, landscape or alter any existing
stormwater BMP without the written approval of the municipality unless
it is part of an approved maintenance program.
No person shall place any structure, fill, landscaping or vegetation
into a stormwater BMP or within a drainage easement, which would limit
or alter the functioning of the BMP, without the written approval
of the municipality.
