(A) This subchapter sets requirements for the nonresidential discharge of pollutants into the city sewerage system. The objectives of this subchapter are to:
(1) Prevent the discharge into the city sewerage system of pollutants which will interfere with the operation of the system or contaminate the resulting sludge;
(2) Prevent the discharge into the city sewerage system of pollutants which will pass through the system, inadequately treated, into receiving streams; and
(3) Improve the opportunity to recycle and reclaim wastewater and sludge from the city sewerage system.
(B) In achieving the objectives of this subchapter, it shall be the policy of the city to actively support the community’s commerce and industry through accommodation, assistance and cooperation consistent with the city’s responsibility to protect the waters of the state from pollution and to secure the health, safety and welfare of the city’s residents.
(C) Pollutants shall be accepted into the city sewerage system subject to regulations and requirements as may be promulgated by state and federal regulatory agencies or the city for the protection of sewerage facilities and treatment processes, public health and safety, receiving water quality and avoidance of nuisance. At a minimum, nonresidential users of the city sewerage system shall comply with the applicable pretreatment standards developed under state (OAR 340-45-063) and federal (40 C.F.R. part 403) regulations. Pretreatment standards shall be developed to ensure that at a minimum the city and nonresidential users comply with § 307(b) and (c) of the federal Water Pollution Control Act as amended by the Clean Water Act of 1977, being 33 U.S.C. § 1717(b) and (c) and the regulations promulgated pursuant to these sections of the Act.
(D) (1) Wastewater discharge permit conditions shall be based on federal, state and local regulations and requirements and on the results of analysis of the type, concentration, quantity and frequency of discharge including the geographical relationship of the point of discharge to sewerage and treatment facilities.
(2) These permit conditions shall be reevaluated upon expiration of the permit and may be revised from time to time as required to remain consistent with local, state or federal laws, regulations and requirements or to meet any emergency. Wastewater discharge permits may include, but shall not be limited to, conditions pertaining to discharge standards, self-monitoring requirements, treatment methods, housekeeping practices, inventory storage, manufacturing methods and the like that are intended to protect the waters of the state.
(E) Except as otherwise provided herein, the City Manager shall administer, implement and enforce the provisions of this subchapter.
