The following described substances, materials, waters, 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 maintain and protect water quality in the receiving stream, or will not otherwise endanger lives, limb, public property, or constitute a nuisance. The Public Works Director may set additional limitations or limitations more stringent than those established in the regulations below if in his opinion more severe limitations are necessary to meet the above objectives. In forming his opinion as to the acceptability of a discharge, the Public Works Director shall 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, and other pertinent factors.
