Users shall make wastewater acceptable under the limitations established in these regulations before discharging to a community sewer. Any pretreatment facilities required to pretreat wastewater to a level acceptable to the city shall be provided and maintained at the user’s expense. When pretreatment or special facilities are required to make the industrial wastes acceptable, the industrial user shall be required to furnish a compliance schedule and plans, approved prior to construction, showing the schedule of activities, time frame and method of pretreatment proposed to meet applicable pretreatment standards and requirements. The industrial user shall also submit all notices and self-monitoring reports required by the city necessary to assess and assure compliance by the industrial user with pretreatment standards and requirements. Pretreatment facilities or measures shall be installed in conformity with the approved plans and other city codes or regulations. The approval of the pretreatment method will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the city under the provisions of these regulations. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be accepted by the city.

The effectiveness of the pretreatment unit discharging to the community sewer will be monitored by the city at the discharger’s expense. All records relating to compliance of the pretreatment unit with discharge standards shall be made available to the EPA or approval authority.

In addition to pretreatment, or separately, the city may require the user to develop and adopt a waste minimization or pollution prevention plan to reduce the quantity of waste discharged to the POTW. If determined necessary, the city may require the user to control slug discharges and provide a slug discharge control plan under 40 CFR 403.8(f)(1)(B)(6). If determined necessary, the city may require the user to control nuisances as defined in Section 15.44.020(A)(48). (Ord. 2282 NCS §3 (part), 2007.)
