A.
This
chapter sets forth uniform requirements for direct and indirect contributors
into the wastewater collection and treatment system for the city and
enables the city 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.)
B.
The
objectives of this chapter 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; and
4.
To
provide for equitable distribution of the cost of the municipal wastewater
system.
C.
This
chapter 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 customers' capacity
will not be preempted, and provides for the setting of fees for the
equitable distribution of costs resulting from the program established
in this chapter.
D.
This
chapter shall apply to persons in the city and to persons outside
the city who are users of the city publicly-owned treatment works.
(Ord. 1718 § 1, 1983)
Except as otherwise provided, the environmental utilities director
