(A) Industrial users shall provide necessary wastewater treatment as required to comply with the most stringent of this subchapter, federal pretreatment standard, as established by 40 CFR Chapter I, Subpart N, State standards and permit conditions, and shall achieve compliance with all national categorical pretreatment standards within the time limitations, as specified by the federal pretreatment regulations, and with any other pretreatment standards by applicable deadlines.
(B) Any facilities required to pretreat wastewater shall be provided, operated, and maintained at the industrial user’s expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the POTW for review, and shall be approved by the POTW before construction of the facility. The review and approval of plans and operating procedures does not relieve the industrial user from complying with the provisions of this subchapter and permit conditions. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and approved by the POTW prior to the industrial user’s initiation of the changes.
(C) When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the Department Head shall impose an alternate limit using the combined waste stream formula in. 40 CFR 403.6(e).
(D) The Department Head is authorized to establish and enforce specific limits pursuant to 40 CFR 403.5(c). These limits shall continue to be developed, as necessary to ensure renewed and continued compliance with the POTW’s NPDES permit or sludge use or disposal practices. Specific effluent limits shall not be developed or enforced, without individual notice to persons or groups who have requested such notice and an opportunity to respond.
(E) Where specific prohibitions or limits on pollutants or pollutant parameters are developed by a POTW, as stated above, such limits shall be deemed local limits and pretreatment standards for the purposes of § 307(d) of the Act.
(F) The pollutant limits are established to protect against pass through and interference. No person shall discharge wastewater containing pollutants in excess of the limits stated in § 52.128(B)(10). The above limits apply at the point where the wastewater is discharged to the POTW. All concentrations for metallic substances are for total metal unless indicated otherwise. The department head may impose mass limitations in addition to the concentration-based limitations above. The city or Department Head may develop best management practices (BMPs), by ordinance or in individual wastewater discharge permits or general permits, to implement specific limits and the requirements of § 52.128. Such BMPs shall be considered local limits and pretreatment standards for the purposes of § 307(d) of the Act.
(G) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Department Head, 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 Department Head and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired by the user at their expense.
(H) Hauled wastewater. Septic tank waste may be introduced into the POTW only at locations designated by the Department Head and at such times as are established by the Department Head. Such waste shall not violate § 52.128 or any other requirements established by the Department Head or city. The Department Head may require septic tank waste haulers to obtain individual wastewater discharge permits.
(I) The Department Head may require haulers of industrial waste to obtain individual wastewater discharge permits. The Department Head may require generators of hauled industrial waste to obtain individual wastewater discharge permits. The Department Head also may prohibit the disposal of hauled industrial waste. The discharge of hauled industrial waste is subject to all other requirements of this subchapter.
(J) Industrial waste haulers may discharge loads only at locations designated by the Department Head. No load may be discharged without prior consent of the Department Head. The Department Head may collect samples of each hauled load to ensure compliance with applicable standards. The Department Head may require the industrial waste hauler to provide a waste analysis of any load prior to discharge.
(K) Industrial waste haulers must provide a waste-tracking form for every load. This form shall include, at a minimum, the name and address of the industrial waste hauler, permit number, truck identification, names and addresses of sources of waste, and volume and characteristics of waste. The form shall identify the type of industry, known or suspected waste constituents, and whether any wastes are RCRA hazardous wastes.
