<br /> <br /> <br /> <br /> <br /> <br /> I. FEDERAL CATEGORICAL PRETREATMENT STANDARDS <br /> <br /> When promulgated, Federal Categorical Pretreatment <br /> Standards for a particular category, if more stringent than <br /> the limitations imposed by this ordinance for users in that <br /> category or subcategory, shall immediately supercede the <br /> limitations imposed under this chapter. The Supervisor <br /> shall notify all affected users of the applicable reporting <br /> requirements under 40 CFR, SEction 403.12. <br /> J. MODIFICATION OF FEDERAL CATEGORICAL <br /> PRETREATMENT STANDARDS <br /> Where the City wastewater treatment system achieves <br /> consistent removal of pollutants limited by federal <br /> pretreatment standards, the City may apply to the <br /> Administrator of the EPA for modification of the specific <br /> limit(s) in the federal pretreatment standards. "Consistent <br /> removal" shall be defined as reduction in the amount of a <br /> pollutant or alteration of the nature of the pollutant by the <br /> wastewater treatment system to a less toxic or a harmless <br /> state in the effluent as defined by the Code of Federal <br /> Regulations (CFR). <br /> K. REQUIREMENTS FOR TRAPS <br /> Any user discharging oil, sand, flammable wastes, <br /> grease or wastes containing grease in amounts that will <br /> impede or stop the flow in public sewers shall at his own <br /> cost and expense and as required by the provisions herein <br /> provide interceptors or traps of a type and capacity <br /> approved by the City with the following features: <br /> 1) Impervious material construction capable of <br /> withstanding abrupt and extreme changes in <br /> temperature ; <br /> 2) Watertight and equipped with easily removable <br /> covers which, when bolted in place, shall be <br /> gastight and watertight; <br /> 3) Located as to be readily and easily accessible for <br /> cleaning and inspection; <br /> 4) Maintained by the owner or user at his own cost <br /> and expense; <br /> 5) In continuous and efficient operation at all times. <br /> Approval of traps and interceptors shall be obtained <br /> from the City Engineer. Approval shall in no way relieve <br /> the user from providing traps and/or interceptors of <br /> adequate size and design to bring all discharges into <br /> compliance with this ordinance. The user shall maintain for <br /> a period of at least the previous twelve (12) months records <br /> of cleaning of any traps and/or interceptors in his use. <br /> These records shall contain at a minimum the name and <br /> address of the person performing the cleaning service and <br /> the dates the service is performed. <br /> A permit shall be required for operation of traps and <br /> interceptors connected to the POTW when a wastewater <br /> contribution permit is not in effect for the user. A yearly <br /> permit fee shall be charged to cover periodic inspection. <br /> This fee shall appear on the regular monthly bill unless <br /> otherwise directed by the Finance Director. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> 18 <br />
