The objectives of this article are to:
(1) Prevent the introduction of pollutants into the Publicly Owned Treatment Works that will interfere with its operation and efficient functioning of its parts;
(2) Prevent the introduction of pollutants into the Publicly Owned Treatment Works that will pass through the Publicly Owned Treatment Works, inadequately treated, into receiving waters, or otherwise be incompatible with the Publicly Owned Treatment Works;
(3) 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;
(4) Promote reuse and recycling of industrial wastewater and sludge away from the Publicly Owned Treatment Works;
(5) Provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the Publicly Owned Treatment Works;
(6) Enable the city to comply with its Arizona 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;
(7) Promote waste minimization and pollution prevention; and
(8) Protect the environment.
(b) This article shall apply to all persons discharging to the Publicly Owned Treatment Works. This article establishes discharge prohibitions/limitations; 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.
