A. Whenever deemed necessary, the Director may require Industrial Users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the Industrial User’s compliance with the requirements of this ordinance.

B. The Director may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow. An industrial wastewater discharge permit may be issued solely for flow equalization.

C. The Director may require any person discharging into the POTW to install and maintain, on their property and at their expense grease, oil, and sand interceptors when, in the opinion of the Director, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or sand; except that such interceptors shall not be required for residential users. All interception units shall be of a type and capacity approved by the Director, and shall be so located to be easily accessible for cleaning, sampling and inspection. Such interceptors shall be inspected, cleaned, and repaired by the user at their expense.

D. In the event the city, during maintenance of public sewer lines, record situations of grease accumulation in lines sufficient to restrict the normal flow of waste, upstream users shall be inspected. If the Director determines that an upstream user is responsible for the grease or oil discharge, the user will be required to cease discharge of the prohibited waste. Additionally, the user may be required to install an interceptor, maintain the interceptor, and may be charged for the cost

of cleaning the line. When an obstruction of the public line occurs, a violation of 40 CFR 403.5(b)(3) or (6) and MMC 13.05.010(B), Specific Prohibitions, has occurred.

E. Industrial Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter. (Ord. 4987, 2015).
