Any person who introduces or causes to be introduced into the system, either directly or indirectly, any pollutant or wastewater which creates a stoppage, plugging, breakage, reduction in the capacity of any portion of the system or any other damage to the system shall be liable for the damage and for maintenance, operation, and replacement expenses, including overhead costs, occasioned thereby. Expense of the damage, any excessive maintenance expense, or any other expenses attributable thereto shall be deemed a debt to the city and shall be charged to the offending person by the city manager.
(`64 Code, Sec. 25-9) (Ord. No. 2494)
Any person who introduces or causes to be introduced into the system, either directly or indirectly, any prohibited pollutant or wastewater which causes detrimental effects to the city's system or treatment plant processes or causes a violation of the city's NPDES permit or other regulation imposed by a regulatory agency shall be liable for all damages and costs occasioned thereby, including any penalty assessed by a regulatory agency. The damages, costs or penalty assessed shall be deemed a debt to the city and shall be charged to the offending person by the city manager.
(`64 Code, Sec. 25-10) (Ord. No. 2494)
(A) In addition to the payment of a connection fee, any person requesting service to a lot that is not adjacent to the system shall be responsible for installation of a sewer extension in dedicated streets, alleys or easements accepted by the city. Sewers shall be installed in sewer easements only when it is not in the public interest for the city to accept dedication of a street or alley in the particular location. The required sewer extension shall include all facilities necessary to serve the property as well as all abutting sewers indicated by the sewer master plan. All construction shall conform to city standards and detailed plans approved by the city manager. The city manager shall determine the size sewer required for the area for which application for service is made. A sewer shall not have an inside diameter of less than eight inches. In the case of sewer trunk mains in the sewer master plan, an appropriate credit against collection fees and cash reimbursement may be allowed in an amount to be determined by the city manager.
(B) If sewer facilities that the person would otherwise be required to provide have previously been installed, the person shall be required to pay to the city a sewer charge consisting of a pro rata share of such facilities as determined by the city manager. If such previous installation was made by the applicant or his/her predecessor in interest in the property to which service is desired, the applicant may be entitled to credit in an amount to be determined by the city manager for such installation. Previous installations eligible for these credits must have been made less than 20 years before the application. Credit for previous installations will be applied against sewer charges, but in no event shall such credits be greater than the amount paid for actual construction of the extension.
(C) When installed, connected and finally inspected, all sewer extensions shall be deemed automatically offered for dedication to the city and upon acceptance shall become the property of the city. All necessary easements shall be granted to the city.
(`64 Code, Sec. 25-11) (Ord. No. 2494)
(A) When an application requires a sewer extension and it is necessary or desirable to design the extension to serve an area or users, actual or potential, in excess for that which the application is made, the applicant may be eligible for a credit for a portion of the design and construction costs for the extension. Any such credit shall be granted in an amount to be determined by the city manager.
(B) If the sewer to be constructed is included in the current sewer master plan implementation schedule, and said sewer is constructed, in part, by the applicant, the city manager may authorize an appropriate credit against the applicant's sewer connection fee. No applicant may receive a credit for more than the total amount of sewer connection fees that would be normally required of the applicant. Any credit granted by the city manager shall only be for the actual engineering and construction costs of the sewer.
(C) Upon completion of a sewer which is not in the current sewer master plan implementation schedule and to which future connections could be made, the city manager shall determine the actual cost thereof and the existing sewer charge against each front foot of abutting property, taking into consideration intersections and other property that would not receive water service.

DIVISION 3. WASTEWATER INTRODUCTION INTO THE CITY'S MUNICIPAL WASTEWATER SYSTEM
(A) No person shall introduce or cause to be introduced to the system, directly or indirectly, any pollutant or wastewater that causes pass through or interference. These general prohibitions apply to all persons, whether or not they are subject to categorical pretreatment standards or any other federal, State or local pretreatment standards or requirements.
(B) No person shall introduce or cause to be introduced into the system the following pollutants, substances, or wastewater:
(1) Pollutants that create a fire or explosive hazard in the system, including, but not limited to, waste streams with a closed-cup flashpoint of less than 140 degrees Fahrenheit (60 degrees Celsius) using the test methods specified in 40 CFR Part 261.21;
(2) Any pollutant or wastewater having a pH less than 6.0 or more than 10.0, or that may otherwise cause corrosive structural damage to the city system or equipment;
(3) Solid or viscous substances in amounts that will cause obstruction of the flow in the system resulting in interference but in no case solids greater than ½-inch (1.27 centimeters) in any dimension;
(4) Pollutants, including oxygen-demanding pollutants, released in a discharge at a flow rate and/or pollutant concentration that, either singly or by interaction with other pollutants, will cause interference with the system;
(5) Wastewater having a temperature greater than 140 degrees Fahrenheit (60 degrees Celsius), or that will inhibit biological activity in the treatment plant resulting in interference, but in no case wastewater that causes the temperature at the introduction into the treatment plant to exceed 104 degrees Fahrenheit (40 degrees Celsius);
(6) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through;
(7) Pollutants that result in the presence of toxic gases, vapors, or fumes within the system in a quantity that may cause acute worker health and safety problems;
(8) Trucked or hauled pollutants, except at discharge points designated by the city manager in accordance with section 19-41 of this article;
(9) Noxious or malodorous liquids, gases, solids, or other wastewater that, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life, or to prevent entry into the sewers for maintenance or repair;
(10) Wastewater that imparts color that cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant's effluent, thereby violating the city's NPDES permit;
(11) Wastewater containing any radioactive wastes or isotopes except in compliance with applicable State or federal regulations;
(12) Storm water, surface water, ground water, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, single pass noncontact cooling water and unpolluted wastewater, unless specifically authorized by the city manager;
(13) Sludges, screenings, or other residues from the pretreatment of industrial wastes, except as specifically authorized by the city manager;
(14) Medical wastes, except as specifically authorized by the city manager in an IWD permit;
(15) Wastewater causing, alone or in conjunction with other sources, the treatment plant's effluent to fail a toxicity test;
(16) Detergents, surface-active agents, or other substances that may cause excessive foaming in the system;
(17) Wastes defined as hazardous waste by RCRA or the California Hazardous Waste Control Law; and/or
(18) Wastewater, when measured with a combustible gas indicator, at the point of discharge into the system or at any point in the system, that results in two readings over 5% or any single reading over 10% of the lower explosive limit of the combustible gas indicator.
(C) No person shall process or store pollutants, substances, or wastewater prohibited by this section in such a manner that they could be discharged to the system.
(D) No person shall discharge any domestic or industrial wastewater to the ground, into any surface drainage conduit, storm drain or channel, or stream or other water course.
(E) Any industrial user obtaining a new permit after the effective date of this provision to discharge to the sewer shall not discharge wastewater containing total dissolved solids (TDS) at concentrations exceeding 1,850 mg/L. This provision shall become effective on the date the approval authority issues its approval of City Ordinance 19-25.
(1) Any industrial users currently permitted to discharge to the sewer prior to the effective date of this provision shall be held to a baseline TDS discharge concentration and loading. This provision shall become effective on the date the approval authority issues its approval of Ordinance No. 2997. This requirement shall be incorporated into individual discharge permits. Industrial users shall be required to establish a baseline TDS concentration and loading based on data collected during a site specific sampling plan approved by the city.
(F) Any industrial user obtaining a new permit after the effective date of this provision to discharge to the sewer shall not discharge wastewater containing boron at concentrations exceeding 1.86 mg/L. This provision shall become effective on the date the approval authority issues its approval of Ordinance No. 2997.
(1) Any industrial users currently permitted to discharge to the sewer prior to the effective date of this provision shall be held to a baseline boron discharge concentration and loading. This provision shall become effective on the date the approval authority issues its approval of Ordinance No. 2997. This requirement shall be incorporated into individual discharge permits. Industrial users shall be required to establish a baseline boron concentration and loading, based on data collected during a site specific sampling plan approved by the city.
(G) Centralized waste treatment (CWT) facilities subject to 40 CFR 437 Subcategory D must comply with the "Best Management Practices for Centralized Waste Treatment (CWT) Facilities (Subcategory D Multiple Wastestream)", developed by the California Association of Sanitation Agencies (CASA), February 29, 2016, and any subsequent versions and amendments. Compliance with the CASA BMPs shall be demonstrated before issuance of an industrial waste discharge permit. CWTs that do not fall within Subcategory D, but are classified as Subcategories A, B, or C must comply with all applicable requirements as established in the CASA document.
(H) No person shall discharge or cause to be discharged wastewater (untreated or treated) produced as a byproduct of oil production, drilling fluids or completion fluids from oil and gas well drilling, and fluids associated with or generated during hydraulic fracturing into the sewer system.
(I) No industrial user or person shall discharge or cause to be discharged organic solvents into the sewer system or use the sewer as a means of disposal for organic solvents. Industrial users having organic solvents on site shall provide and use a separate collection and disposal system outside the sewer system and shall provide safeguards against their accidental discharge to the sewer. An approved toxic organic management plan (TOMP) that includes control measures to prevent entry of toxic organics and other solvents into the sanitary sewer system shall be filed by the industrial user as a condition of permission to discharge to the sanitary sewer. The TOMP shall be updated whenever any significant change in the inventory, usage, or management of toxic organic compounds occurs. The updated TOMP shall be submitted to the City of Oxnard for approval. Records documenting appropriate disposal and handling of organic solvents shall be maintained for a period of three years and made available for inspection. Any accidental solvent discharges shall be reported to the city within 24 hours of the discharge.
(J) No industrial user, dental discharger or person shall discharge or cause to be discharged any mercury or amalgam waste into the sewer system. All dental dischargers that place or remove amalgam must operate and maintain an amalgam separator that complies with ANSI/ADA Specifications 108 (2009) with Technical Addendum (2011) or ISO 11143 Dentistry-Amalgam Separators and any subsequent versions or amendments. The dental discharger shall comply with the most recent Best Management Practices for Dental Amalgam Waste as recommended by the American Dental Association, and specified in 40 CFR 441 (Effluent Limitations Guidelines and Standards for the Dental Category) June 14, 2017. Records documenting appropriate handling and disposal of mercury and amalgam shall be maintained for three years and made available for inspection.
(K) No industrial user or person shall discharge or cause to be discharged wastewater that exceeds any applicable site-specific limitation for gross beta radioactivity established by the city. The maximum allowable industrial loading (MAIL) to the wastewater treatment plant for gross beta radioactivity is 6.29 X 108 pCi/d. Any SIU that has the potential to discharge gross beta radioactivity at concentrations that may cause interference or pass-through at the POTW will be issued a site-specific limitation based on an allocation of the MAIL established by the city. The site-specific limitation will be incorporated into the individual SIU's discharge permit.
