Sec. 19-4-2. Wastewater discharge permits in general.

(a) Wastewater discharge permits issued by the city shall be of two types:
(1) Industrial wastewater discharge permits issued to CIUs and SIUs as required by this chapter or the director.
(2) Pollution prevention permits issued to other users as required by this chapter or the director.
(b) Any new SIU or CIU proposing to discharge to, connect to, or to contribute to the WPCF shall obtain an industrial wastewater discharge permit before discharging to, connecting to, or contributing to the WPCF. New CIUs and SIUs, and other new users required by the public works director to obtain a permit, shall apply for the permit at least ninety days prior to discharging to, connecting to, or contributing to the WPCF. All existing SIUs or CIUs discharging, connected to, or contributing to the WPCF shall obtain an industrial wastewater discharge permit within one hundred eighty days after the effective date of the ordinance codified in this chapter.
(c) The director may require any user which is not a CIU or SIU to obtain a pollution prevention permit as necessary to carry out the purposes of this chapter. The primary criteria for the requirement of a pollution prevention permit shall be: (1) dischargers (whether or not industrial) which have the potential to be regulated under the WIPP in the future; (2) dischargers (whether or not industrial) or industries which discharge a pollutant of concern; or (3) dischargers (whether or not industrial) or industries which discharge a substance regulated or proposed to be regulated pursuant to a narrative, numeric, or toxicity-based water quality objective of the CTR, the NTR or of a water quality plan adopted or proposed to be adopted by the SWRCB pursuant to Water Code Section 13170. (Ord. No. 1271, § 1 (part).)
