Users shall provide necessary wastewater treatment as required to comply with this chapter and shall achieve compliance with all Federal categorical pretreatment standards and schedules where applicable. Any nondomestic user of any Otsego POTW may be required to have a pretreatment agreement and will be required to achieve certain pollutant discharge limits. If pretreatment is necessary to achieve these limits, the facility constructed/installed to meet the limits shall be provided, operated and maintained at the user/owner's expense.
A. Pretreatment Agreement: Any violation of the terms and conditions of a wastewater pretreatment agreement shall be deemed a violation of this chapter and subjects the nondomestic user to extra sewer charges and sanctions described in the agreement. Obtaining a pretreatment agreement does not relieve a user of its obligation to comply with all Federal, State, or local laws. The wastewater pretreatment agreement may require pretreatment of industrial wastewaters prior to discharge to any Otsego POTW, flow equalization to reduce peak flows, discharge of certain wastes only to specific sewers, relocation of discharge points, prohibition of certain discharges, restriction of some discharges to specific hours of the day, payment of charges to defray costs that may be related to specific discharges, extra charges for discharges over limits, and other conditions that may be needed to implement activities consistent with the intent of this chapter. No person shall discharge wastewater to any Otsego POTW in excess of the quantity or quality limits established in the wastewater pretreatment agreement. A schedule for complying with agreement requirements, effluent limits, self-monitoring requirements or other requirements deemed necessary by the Director shall be submitted to the City for approval by the nondomestic user in a time frame established by the Director. The Director may require compliance schedule progress reports, a report on final compliance with effluent limits and standards, and periodic reports on continued compliance. The Director may require a nondomestic user to submit to compliance independent of a compliance schedule.
B. Federal Categorical Pretreatment Standards: Upon the promulgation of the Federal categorical pretreatment standards for a particular industrial subcategory, the Federal standard, if more stringent than limitations imposed under this Code for sources in that subcategory, shall immediately supersede the limitations imposed under this Code. The Director shall notify all affected users of the applicable reporting requirements under 40 CFR section 403.12.
C. Federal Categorical Pretreatment Modifications: Where the City's wastewater treatment system achieves consistent removal of pollutants limited by Federal pretreatment standards, the City may apply to the approval authority for modification of specific limits in the Federal pretreatment standards. Consistent removal shall mean reduction in the amount of a pollutant or alteration of the nature of the pollutant by the wastewater treatment system to a less toxic or harmless state in the effluent which is achieved by the system in ninety five percent (95%) of the samples taken when measured according to the procedures set forth in section 403.7(c)(2) of title 40 of the Code of Federal Regulations, General Pretreatment Regulations for Existing and New Sources of Pollution promulgated pursuant to the Act. The City may then modify pollutant discharge limits in the Federal pretreatment standards if the requirements contained in 40 CFR section 403.7 are fulfilled and prior approval from the approval authority is obtained.
