If the holder of a wastewater discharge permit wishes to continue discharging after the expiration date of the permit, an application shall be filed for renewal of the permit at least 180 days prior to the expiration date. Applications for renewal approvals shall be processed in accordance with the requirements of this section, with the exception of the public notice requirement. An industrial user whose existing waste discharge permit has expired and has submitted its complete application for permit renewal in the time specified herein shall be deemed to have an effective waste discharge permit until the director issues or denies the new waste discharge permit. An industrial user whose existing waste discharge permit has expired and who failed to submit its reapplication in the time period specified herein will be deemed to be discharging without a waste discharge permit. The director may extend the wastewater discharge permit upon finding that the interests of this chapter are best served by such extension. [Ord. 2020-07-016 § 1; Ord. 2019-11-032 § 1].
