[Amended 4-16-2025 by Ord. No. 2486-25]
A. 
Any drain or conveyance, whether on the surface or subsurface, that allows any nonstormwater discharge, including sewage, process wastewater, or wash water to enter a regulated small municipal separate storm sewer system (MS4) or to enter the surface waters of the commonwealth is prohibited. Any connections to the storm drain system from indoor drains and sinks are also prohibited.
B. 
No person shall allow, or cause to allow, discharges into a regulated small MS4, or discharges into surface waters of the commonwealth which are not composed entirely of stormwater, except (1) as provided in Subsection C below, and (2) discharges allowed under a state or federal permit.
C. 
The following discharges are authorized unless they are determined to be significant contributors to pollution to a regulated small MS4 or to the waters of the commonwealth:
(1) 
Discharges or flows from firefighting activities.
(2) 
Discharges from potable water sources including water line flushing and fire hydrant flushing, if such discharges do not contain detectable concentrations of total residual chlorine (TRC).
(3) 
Non-contaminated irrigation water, water from lawn maintenance, landscape drainage and flows from riparian habitats and wetlands.
(4) 
Diverted stream flows and springs.
(5) 
Non-contaminated pumped ground water and water from foundation and footing drains and crawl space pumps.
(6) 
Non-contaminated HVAC condensation and water from geothermal systems.
(7) 
Residential (i.e., not commercial) vehicle wash water where cleaning agents are not utilized.
(8) 
Non-contaminated hydrostatic test water discharges, if such discharges do not contain detectable concentrations of TRC.
D. 
In the event that the municipality or DEP determines that any of the discharges identified in Subsection C significantly contribute pollutants to a regulated small MS4 or to the waters of the commonwealth, the municipality or DEP will notify the responsible person(s) to cease the discharge.
[Amended 4-16-2025 by Ord. No. 2486-25]
A. 
Roof drains and sump pumps shall not be connected to streets, sanitary or storm sewers, or roadside ditches, and shall discharge to infiltration areas or vegetative BMPs to the maximum extent practicable, except for already existing developed sites where the on-site stormwater system already is designed and equipped to accomplish stormwater rate, quality, and quantity mitigation. The applicant shall, in these cases, submit documentation on the existing stormwater system to the Municipal Engineer, who shall determine if the stormwater system accomplishes comparable stormwater rate, quality, and quantity mitigation.
B. 
In the event that an existing developed site is to be redeveloped, existing roof drains that discharge to an existing stormwater system that is designed and equipped to accomplish stormwater rate, quality, and quantity mitigation, those existing roof drains may remain, provided the applicant submits documentation on the existing stormwater system to the Municipal Engineer, who shall determine if the stormwater system accomplishes comparable stormwater rate, quality, and quantity mitigation.
[Amended 4-16-2025 by Ord. No. 2486-25]
A. 
No person shall modify, remove, fill, landscape, or alter any SWM BMPs, facilities, areas, or structures that were installed as a requirement of this chapter unless it is part of an approved maintenance program and written approval of the municipality has been obtained.
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.
