A. 
This Part 4 sets forth uniform requirements for direct and indirect contributors into the wastewater collection and treatment system for the municipality and enables the municipality to comply with all applicable state and federal laws required by the Clean Water Act of 1977 and the General Pretreatment Regulations (40 CFR 403).
B. 
The objectives of this Part 4 are:
(1) 
To prevent the introduction of pollutants into the municipal wastewater system which will interfere with the operation of the system or contaminate the resulting sludge.
(2) 
To prevent the introduction of pollutants into the municipal wastewater system which will pass through the system inadequately treated into receiving waters or the atmosphere or otherwise be incompatible with the system.
(3) 
To improve the opportunity to recycle and reclaim wastewaters and sludges from the system.
(4) 
To provide for equitable distribution of the cost of the municipal wastewater system.
C. 
This Part 4 provides for the regulation of direct and indirect contributors to the municipal wastewater system through the issuance of permits to certain nondomestic users and through enforcement of general requirements for the other users, authorizes monitoring and enforcement activities, requires user reporting, assumes that existing customer capacity will not be preempted and provides for the setting of fees for the equitable distribution of costs resulting from the program established herein.
This Part 4 shall apply to the municipality and to persons outside the municipality who are, by contract or agreement with the municipality, users of the municipal POTW. Except as otherwise provided herein, the Municipal Engineer of the municipality shall administer, implement and enforce the provisions of this Part 4.
