Sewer PreTreatment Ordinance

This ordinance sets forth uniform requirement for user of the Publicly Owned Treatment Works for the City of Peru and for the Grissom Aeroplex and enables the City to comply with all applicable State and Federal laws, including the Clean Water Act (33 United States Code § 1251 et seq.) And the General Pretreatment Regulations (40 CFR Par 403). The objectives of this ordinance are:

A. To prevent the introduction of pollutants into the Publicly Owned Treatment Works that will interfere with its operation;
B. To prevent the introduction of pollutants into the Publicly Owned Treatment Works that will pass through the Publicly Owned Treatment Works, inadequately treated, into receiving water, or otherwise be incompatible with the Publicly Owned Treatment Works;
C. To protect both Publicly Owned Treatment Works personnel who may be affected by wastewater and sludge in the course of their employment and the general public;
D. To promote reuse and recycling of industrial wastewater and sludge from the Publicly Owned Treatment Works;
E. To provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the Publicly Owned Treatment Works; and
F. To enable the City to comply with the two National Pollutant Discharge Elimination System Permit conditions, sludge use and disposal requirements, and any other Federal or State laws to which the Publicly Owned Treatment Works is subject.

This ordinance shall apply to all users of the Publicly Owned Treatment Works. The ordinance authorizes the issuance of wastewater discharge permits; provides for monitoring, compliance, and enforcement activities; establishes administrative review procedures; requires user reporting; and provides for the setting of fees for the equitable distribution of costs resulting from the program established herein.

Except as otherwise provided herein, the Utilities’ Superintendent shall administer, implement, and enforce the provisions of this ordinance. Any powers granted to or duties imposed upon the Superintendent may be delegated by the Superintendent to other City Utilities personnel.
