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.
Nothing in this section shall affect a discharger's responsibilities under state law.
The following connections are prohibited, except as provided in § 139-36B above:
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.
Roof drains shall not be connected to streets, sanitary or storm sewers or roadside ditches, except as provided in § 139-38B.
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.
Roof drains shall discharge to infiltration areas or vegetative BMPs to the maximum extent practicable.
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.
