A. Any person found to be violating any provision of this chapter except Section 13.16.160 shall be served by the city with written notice stating the nature of the violation and providing a reasonable time limit for satisfactory correction thereof. The offender/user shall, within the period of time stated in such notice, permanently cease all violations.

B. In terms of harmful contributions by industrial users the city may suspend the wastewater treatment service and/or a wastewater contribution contract when such suspension is necessary, in the opinion of the director of public utilities, 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, danger to the environment, causes interference to the POTW, or causes the city to violate any condition of its NPDES permit. Any person notified of a suspension of the wastewater treatment service and/or the wastewater contribution contract shall immediately stop or eliminate the contribution. In the event of a failure of the person to comply voluntarily with the suspension order, the director of public utilities shall take such 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 contribution contract and/or the wastewater treatment service upon proof of elimination of the non-complying discharge. A detailed written statement submitted by the user describing the causes of the harmful contribution and the measures taken to prevent any future occurrence shall be submitted to the director of public utilities within fifteen (15) days of the date of occurrence.
