A. Significant industrial users shall not discharge wastewater to the POTW without first obtaining a wastewater discharge permit.

B. The director may require any other user to obtain a wastewater discharge permit, as necessary to carry out the purposes of this chapter.

C. The director may issue a conditional discharge authorization letter to any user that is not required to obtain a wastewater discharge permit in order to impose appropriate discharge conditions upon such user, including, but not limited to, requiring such user to implement pretreatment and/or best management practices, as necessary, to carry out the purposes of this chapter. The director may also issue a conditional discharge authorization letter to allow prohibited discharges, subject to appropriate conditions.

D. The conditions and discharge limitations contained in wastewater discharge permits and conditional discharge authorization letters shall be based on federal, state, county, and city regulations and on the results of analysis of the type, concentration, quantity, and frequency of discharge, including the geographical relationship of the point of discharge to the POTW. The conditions and discharge limitations shall be reevaluated upon expiration of the written discharge approval and may be revised from time to time as required by county, state, or federal regulations and requirements, or to meet any emergency. Obtaining a written discharge approval shall not relieve a user of the obligation to comply with all federal and state pretreatment standards or requirements, or with any other requirements of federal, state, and local law.

E. Any violation of the terms and conditions of a wastewater discharge permit or conditional discharge authorization letter shall be deemed a violation of this chapter and subjects the user to the sanctions set forth herein. [Ord. 2020-07-016 § 1; Ord. 2019-11-032 § 1].
