Any drain or conveyance, whether on the surface or subsurface, that allows any nonstormwater discharge, including sewage, process wastewater, and wash water, to enter the municipality's separate storm sewer system or the waters of the commonwealth is prohibited.
The following discharges are authorized unless they are determined by the municipality to be significant contributors to pollution to the municipality's separate storm sewer system or to the waters of the commonwealth:
Discharges from firefighting activities;
Potable water sources, including water line and fire hydrant flushings;
Water from crawl space pumps;
Pavement wash waters 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;
Diverted stream flows;
Flows from riparian habitats and wetlands;
Uncontaminated water from foundations or from footing drains;
Dechlorinated swimming pool discharges;
Water from individual residential car washing; and
Routine external building washdown (which does not use detergents or other compounds).
In the event that the municipality determines that any of the discharges identified in § 178-1C significantly contribute pollutants to the municipality's separate storm sewer system or to the waters of the commonwealth or is notified of such significant contribution of pollution by PADEP, the municipality will notify the responsible person to cease the discharge.
Upon notice provided by the municipality under § 178-1D, the discharger shall, within a reasonable time period, as determined by the municipality consistent with the degree of pollution caused by the discharge, cease the discharge.
Nothing in this section shall affect a discharger's responsibilities under state law.
The following connections are prohibited, except as provided in § 178-1C above:
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 connected from a commercial or industrial land use to a separate storm sewer system, which has not been documented in plans, maps, or equivalent records and approved by the municipality.
Roof drains and sump pump discharges shall not be connected to sanitary sewers.
Roof drain, sump pump, foundation and footing drain discharges:
To the maximum extent practicable, shall discharge to infiltration or vegetative BMPs or to vegetated or other areas with adequate capacity;
May be connected to streets, storm sewers, or roadside ditches only if determined necessary or acceptable by the Municipal Engineer; and
Shall be considered in stormwater management calculations to demonstrate that conveyance and receiving facilities have adequate capacity.
No person shall modify, remove, fill, landscape, alter, or impair the effectiveness of any stormwater BMPs, conveyances, facilities, areas or structures unless the activity is part of an approved maintenance program, without the written approval of the municipality.
No person shall place any structure, fill, landscaping, additional vegetation, yard waste, brush cuttings, or other waste or debris into a BMP or conveyance, or within a stormwater easement, that would limit or alter the functioning of the stormwater BMP or conveyance, without the written approval of the municipality.
Any construction or other activity which disturbs the surface of the land, including, but not limited to, clearing and grubbing; grading; excavations; embankments; road maintenance; land development; building construction; and the moving, depositing, stockpiling, or storing of soil, rock, or earth materials, shall provide for adequate stormwater management in compliance with the requirements set forth in the East Caln Township Stormwater Management Regulations of 2014, which, including all of its appendixes, shall be appended to the Township Subdivision and Land Development Ordinance as Appendix A and which is incorporated herein by this reference as fully as if set forth here, at length.
