Any drain or conveyance, whether on the surface or subsurface, that allows any nonstormwater discharge, including sewage, process wastewater, and wash water to enter a separate storm sewer system, and any connections to the separate storm sewer system from indoor drains and sinks. Any drain or conveyance that delivers nonstormwater discharges directly into wetlands, riparian buffers, or other waters of the commonwealth is prohibited.

(2) 
May be connected to streets, storm sewers, or roadside ditches only if determined necessary or acceptable by the municipality; and
(3) 
Shall be considered in stormwater management calculations to demonstrate that conveyance and receiving facilities have adequate capacity.
A. 
No person shall modify, remove, fill, landscape, alter, or impair the effectiveness of any stormwater BMPs, conveyances, stormwater management facilities, areas or structures unless the activity is part of an approved maintenance program, without the written approval of the municipality.
