D. Installation and Maintenance. All grease interceptors, oil/water separators, settling <br /> tanks and grit traps shall be properly installed, maintained and operated by the <br /> discharger at his own expense. The installation shall be kept in continuous <br /> operation at all times, and shall be maintained to provide efficient operation. <br /> Cleaning must be performed by a service contractor qualified to perform such <br /> cleaning, or in a manner approved by the Director. All material removed shall be <br /> disposed of in accordance with all state and federal regulations. Records and <br /> certification of maintenance shall be made readily available to the Director for <br /> review and inspection, and must be maintained for a minimum of three (3) years. <br /> If a failure to maintain settling tanks, grit traps, grease interceptors, or oil/water <br /> separators results in partial or complete blockage of the building sewer, private <br /> sewer system discharging to the City Sewer System, or other parts of the City <br /> Sewer System, or adversely affects the treatment or transmission capabilities of the <br /> POTW, or requires excessive maintenance by the City, or poses a possible health <br /> hazard, the discharger responsible for the facilities shall be subject to the remedies <br /> herein, including cost recovery, enforcement and penalties. <br /> 2.9 Deadline for Compliance with Applicable Pretreatment Requirements <br /> Compliance by existing sources (categorical users) covered by Categorical Pretreatment <br /> Standards shall be within 3 years of the date the Standard is effective unless a shorter <br /> compliance time is specified in the appropriate Standard. The City shall establish a final <br /> compliance deadline date for any categorical user when the local limits for said user are <br /> more restrictive than EPA's Categorical Pretreatment Standards. The City may establish a <br /> final compliance deadline date for any existing user not covered by Categorical <br /> Pretreatment Standards. <br /> New source dischargers, and "new users" that are determined to be Significant Industrial <br /> Users (SIU's), are required to comply with applicable pretreatment standards within the <br /> shortest feasible time (not to exceed 90 days from the beginning of discharge). New <br /> Sources, and "new users" that are determined to be Significant Industrial Users (SIU's), <br /> shall install and have in operating condition, and shall "start-up" all pollution control <br /> equipment required to meet applicable pretreatment standards before beginning to <br /> discharge. <br /> Any wastewater discharge permit issued to a categorical user shall not contain a <br /> compliance date beyond any deadline date established in EPA's Categorical Pretreatment <br /> Standards. Any other existing user that is considered to be an SIU, or a categorical user <br /> that must comply with a more stringent local limit, which is in non-compliance with any <br /> local limits shall be provided with a compliance schedule to insure compliance within the <br /> shortest time feasible. <br /> 2.10 Additional Pretreatment Measures <br /> A. Whenever deemed necessary, the Director may require users to restrict their <br /> discharge during peak flow periods, designate that certain wastewater be <br /> discharged only into specific sewers, relocate and/or consolidate points of <br /> discharge, separate sewage wastestreams from industrial wastestreams, and such <br /> other conditions as may be necessary to protect the POTW and determine the <br /> user's compliance with the requirements of this ordinance. <br /> 16 <br />
