A.
Purpose and policy.
(1)
This article sets forth uniform requirements for connected and nonconnected users discharging into the public sanitary sewage system within Tredyffrin Township tributary to the treatment plant of the Valley Forge Sewer Authority and enables Tredyffrin Township and the Authority to comply with all applicable state and federal laws required by the Clean Water Act of 1977 and the General Pretreatment Regulations (40 CFR Part 403).
(2)
The objectives of this article are to:
(a)
Prevent the introduction of pollutants into the public sanitary sewage system and treatment plant which will interfere with the operation of the sewer system or contaminate the resulting biosolids or otherwise be incompatible to the sewer system;
(b)
Prevent the introduction of pollutants into the treatment plant which will pass through the treatment system, inadequately treated, into receiving waters or the atmosphere;
(c)
Improve the opportunity to recycle and reclaim wastes and biosolids from the sewer system; and
(d)
Provide for equitable distribution of the cost of the treatment plant operation and maintenance.
