A. The city, by written order of the director, may prohibit any industrial customer from increasing its flow or BOD or suspended solids beyond its amount of permitted loading as indicated in Exhibit A of Ordinance M-1977 plus (if previously contracted) its reserve capacity; and the department of public works may install devices on facilities serving such customer to prevent excess flows.

B. An industrial customer is considered to be discharging excessive waste quantities when its monthly mass emissions, for any one of the cost allocation parameters, exceed its allocated plus any reserve capacity for a continuous eight-week period by more than five percent. In the case of seasonal users, such excessive emissions shall be deemed exceeded by 10 percent of its allocated plus any reserve capacity for a continuous 10-day period, provided, that, if the seasonal user has advised the director in writing of an anticipated excessive use 15 days prior to the start of the excessive use period, then it shall not be deemed to exceed its allocated or reserve capacities.
