Note: The following language taken from DEP's NPDES program
and model NPDES ordinance is required to be incorporated into this
chapter.
A.
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 and discharges allowed under a state or federal permit.
B.
Discharges that may be allowed based on a finding by the municipality
that the discharge(s) do not significantly contribute to pollution
to surface waters of the commonwealth are:
(1)
Discharges from firefighting.
(2)
Potable water sources, including dechlorinated waterline and fire
hydrant flushings.
(3)
Irrigation drainage.
(4)
Routine external building washdown (which does not use detergents
or other compounds).
(5)
Air-conditioning condensate.
(6)
Water from individual residential car washing.
(7)
Spring water from crawl space pumps.
(8)
Uncontaminated water from foundation or from footing drains.
(9)
Flows from riparian habitats and wetlands.

materials have not occurred (unless all spill material has been removed)
and where detergents are not used.
(12)
Dechlorinated swimming pool discharges.
(13)
Uncontaminated groundwater.
C.
In the event that the municipality determines that any of the discharges identified in Subsection B 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.
D.
Upon notice provided by the municipality under Subsection C, 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.
E.
Nothing in this section shall affect a discharger's responsibilities
under state law.
A.
The following connections are prohibited, except as provided in § 316-38B above:
(1)
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; and
(2)
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.
A.
Roof drains shall not be connected to streets, sanitary or storm
sewers, or roadside ditches in order to promote overland flow and
infiltration/percolation of stormwater where advantageous to do so.
B.
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 as determined by the municipality.
C.
Roof drains shall discharge to infiltration areas or vegetative BMPs
to the maximum extent practicable.
A.
No person shall modify, remove, fill, landscape or alter any existing
stormwater control or BMP unless it is part of an approved maintenance
program without the written approval of the municipality.
B.
No person shall place any structure, fill, landscaping or vegetation
into a stormwater control or BMP or within a drainage easement which
would limit or alter the functioning of the stormwater control or
BMP without the written approval of the municipality.
