The city may suspend the wastewater treatment service and/or a wastewater discharge permit when the suspension is necessary, in the opinion of the city, in order to stop an actual or threatened discharge which presents or may present an imminent or substantial endangerment to the health or welfare of persons, to the environment, causes interference with the operations of the POTW or causes or threatens to cause the city to violate any condition of its NPDES permit. Prior to the suspension, the city will verbally notify an authorized representative of the industrial user of the action. Any person notified of a suspension of the wastewater treatment service and/or the wastewater discharge permit shall immediately stop or eliminate the contribution. In the event of a failure of the person to comply voluntarily with the suspension order, the city shall take steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the POTW system or endangerment to any individuals. The city shall reinstate the wastewater discharge permit and/or the wastewater treatment service upon proof of the elimination of the noncomplying discharge. Users shall notify the city immediately upon having a slug or accidental discharge of substances or wastewater in violation of this subchapter in order to enable countermeasures to be taken by the city to minimize damage to the POTW and the receiving waters. The notification shall include the location of the discharge, date and time of the discharge, type of waste, concentration and volume, and corrective actions taken by the industry following the discharge. Within five days of the date of occurrence, the user shall submit to the city a detailed written statement describing the cause(s) of the discharge and the measures to be taken by the user to prevent similar future occurrences.
