1.1 AUTHORIZATION |
1.2 PURPOSE AND POLICY |
The purpose of this Ordinance is to provide for the regulation of wastewater discharges to the City's Sanitary Sewer Wastewater Collection System which are thereafter discharged to the Western Riverside County Wastewater Treatment Plant. The Ordinance authorizes issuance of individual wastewater discharge permits; provides for monitoring, compliance, and enforcement activities; establishes administrative review procedures; requires User reporting; and provides for setting of fees for the equitable distribution of costs resulting from the program established herein. The Ordinance establishes procedures for complying with requirements placed upon the City by local, State of California, and federal regulations. This Ordinance sets forth the requirements for Users of the Publicly Owned Treatment Works (POTW) for the Western Riverside County Regional Wastewater Authority (the "Authority"), and enables the City and the Authority to comply with all applicable State and Federal laws, including the Clean Water Act (33 U.S.C. Section 1251 et seq.) and the General Pretreatment Regulations (Title 40 CFR Part 403). |
The objectives of this Ordinance are: |
1.2.1 To prevent the introduction of pollutants into the Publicly Owned Treatment Works that will interfere with its operation; |
1.2.2 To prevent the introduction of pollutants into the POTW that will pass through the POTW, inadequately treated, into receiving waters, or otherwise be incompatible with the POTW; |
1.2.3 To protect both POTW personnel who may be affected by wastewater and sludge in the course of their employment and the general public; |
1.2.4 To promote reuse and recycling of industrial wastewater and sludge from the POTW; |
1.2.5 To provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the Publicly Owned Treatment Works; and |
1.2.6 To enable the Authority to comply with its National Pollutant Discharge Elimination System permit conditions, sludge use, and disposal requirements, and any other Federal or State laws to which the POTW is subject. |
1.3 ADMINISTRATION |
This Ordinance shall apply to all discharges, whether direct or indirect, to the City's wastewater system and shall be interpreted in accordance with definitions set forth in Section 1.7 of this Ordinance. This Ordinance provides for the regulation of the quantity and quality of wastewater to be discharged to the regional sewerage system, the degree of waste pretreatment required, the setting of charges to provide for equitable distribution of costs, the issuance of permits for non-domestic wastewater discharge, all other permits as required, and the establishment of penalties for violation of this Ordinance. |
It is the intent of this Ordinance to recognize that the City as a Member Agency with a pretreatment program approved by the Authority has the primary responsibility for compliance monitoring and enforcement of the federal, state and locally mandated pretreatment regulations. However, in the event the City does not take appropriate action to enforce Pretreatment standards and Requirements, the Authority has the right to take administrative or legal action. Any powers granted to or duties imposed upon the Administrator may be delegated by the Administrator to a duly authorized individual. |
1.4 ORDINANCE IN FORCE |
This Ordinance shall be in full force and effect thirty (30) days after final passage thereof. |
1.5 DIRECTOR OF PUBLIC WORKS/CITY ENGINEER |
Except as otherwise provided herein, the City's Director of Public Works shall administer, implement, and enforce the provisions of this Ordinance. |
