No person in Tredyffrin Township shall allow, or cause to allow, stormwater discharges into the Township's separate storm sewer system which are not composed entirely of stormwater, except (1) as provided in Subsection B below; and (2) discharges allowed under a state or federal permit.
Discharges which may be allowed, based on a finding by the Township that the discharge(s) do not significantly contribute to pollution of surface waters of the commonwealth or reduce the hydraulic capacity of the existing storm sewer system, are: discharges from fire-fighting activities; potable water sources including dechlorinated waterline and fire hydrant flushings; irrigation drainage; routine external building washdown (which does not use detergents or other compounds); air-conditioning condensate; water from individual residential car washing; uncontaminated water from foundation or from footing drains; flows from riparian habitats and wetlands; lawn watering; 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. All authorized nonstormwater discharges shall be directed through existing stabilized vegetated areas prior to entering the Township storm sewer system.
In the event that the Township 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 Township will notify the responsible person to cease the discharge.
Upon notice provided by the Township under Subsection C, the discharger will have a reasonable time, as determined by the Township, 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 or federal law.
The following connections are prohibited, except as provided in § 72-2B 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 Tredyffrin Township.
Roof drains shall not be connected to streets, sanitary or storm sewers or roadside ditches/ swales. Roof drains shall be discharged to existing vegetated areas, or shall be discharged into appropriate stormwater BMPs (infiltration, vegetative, etc.) to the maximum extent practicable.

The elimination of prohibited connections or discharges;
Cessation of any violating discharges, practices, or operations;
The abatement or remediation of stormwater pollution or contamination hazards and the restoration of any affected property; and/or
Payment of a fine to cover administrative and remediation costs.
Such notification shall set forth the nature of the violation(s) and establish a time limit for correction of these violation(s). Said notice may further advise that, if applicable, should the violator fail to take the required action within the established deadline, the work may be done by the Township or designee and the expense thereof, including reasonable attorneys' fees and costs, shall be charged to the violator and shall be a lien against the property in question and shall be collected in the manner provided by law for the filing and collection of such liens.
Failure to comply within the time specified shall also subject such responsible person or party to the provisions of §§ 72-6 and 72-7 of this article. All such penalties shall be deemed cumulative and shall not prevent the Township from pursuing any and all other remedies available in law or equity.
