or waste shall be limited in discharges to municipal systems to concentrations
or quantities which will not harm either the sewers, wastewater treatment
process or equipment, will not have an adverse effect on the receiving
stream or will not otherwise endanger lives, limb or public property
or constitute a nuisance. The Director may set limitations lower than
the limitations established in the regulations below if in his or
her opinion such more severe limitations are necessary to meet the
above objectives. In forming his or her opinion as to the acceptability,
the Director will give consideration to such factors as 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 waste in the wastewater treatment plant and
