property, or constitute a nuisance. The
Manager may set limitations lower than any limitations established in the
regulations below if in the Manager’s opinion such more severe limitations are
necessary to meet the above objectives.
In forming his opinion as to the quantity of subject waste in relation
to flows and velocities in the sewers, materials of construction of the sewers,
the wastewater treatment process employed, capacity of the wastewater treatment
plant, degree of treatability of the wastewater treatment plant, and other

cannot meet the requirements of other agencies having jurisdiction over
discharge to the receiving waters.
j. Any
water or wastes which, by interaction with other water or wastes in the public
sewer system, release obnoxious gases, form suspended solids which interfere
with the collection system or create a condition deleterious to structures and
treatment processes.
5. If
any waters are discharged or are proposed to be discharged to the public
sewers, which waters contain the substances or possess the characteristic
enumerated in Subsection 4 of this Section, and which in the judgment of the
Manager, may have a deleterious effect upon the wastewater facilities,
processes, equipment, or receiving waters, or which otherwise create a hazard
to life or constitute a public nuisance, the manager shall
a. Require
pretreatment to an acceptable condition for discharge to the public sewers, or
b. Reject
the wastes.
