(Ord. 2002-15, Added, 11/19/2002)
The city may revoke any wastewater discharge permit, or terminate or restrict or cause to be terminated or restricted wastewater service to any premises, which may include termination or restriction of the water service if warranted, if a violation of any provisions of this chapter is found to exist or if a discharge of wastewater causes or threatens to cause a condition of contamination, pollution or nuisance as defined in this chapter. The city also reserves the right to immediately disconnect any user, upon informal notice only, in the event of an unlawful discharge which may cause imminent danger to human health, the environment, or which threatens to interfere with the treatment plants operation. This provision is in addition to other statutes, rules or regulations, authorizing termination of service for delinquency in payment.
(Ord. 2002-15, Added, 11/19/2002)
No person intending to discharge anything except domestic sewage shall make a connection to the sewer system without first applying to and receiving from the office of the director a wastewater discharge permit. This permit shall be in addition to all other permits required by the director. All significant industrial users proposed to connect or to discharge into a sewerage system after the effective date of the ordinance codified in this Chapter must obtain a wastewater discharge permit before connecting to, or discharging into, a sewerage system. All existing significant users connected to, or discharging into, a sewerage system must apply for a wastewater discharge permit within one hundred eighty days after the effective date of the ordinance codified in this Chapter. All persons desiring to discharge holding tank wastes, and wastes requiring interceptors must also obtain a discharge permit prior to discharging.
(Ord. 2002-15, Added, 11/19/2002)
A.
Persons seeking a wastewater discharge permit shall complete and file with the director of public works an application in the form prescribed by the director, and accompanied by any applicable fees. The applicant may be required to submit, in units and terms appropriate for evaluation, the information on the volume, constituents, and timing of the discharge; and applicable site plans. Applicants will be required to certify the accuracy of the information submitted.
B.
The director will evaluate the data furnished by the user and may require additional information before permit is issued. A permit may be issued subject to terms and conditions provided in this article. Persons discharging under a permit must reapply to the director for a new permit if the person desires to make significant changes to their operations or systems which might alter the nature, quality, or volume of its wastewater.
(Ord. 2002-15, Added, 11/19/2002)
Wastewater discharge permits shall be expressly subject to all provisions of this Chapter and all other regulations, permit charges and fees established by the city council. The conditions of wastewater discharge permits shall be uniformly enforced by the director in accordance with this Chapter, and applicable state and federal regulations. Permits will generally contain discharge limits, pretreatment requirements, reports, and record keeping requirements.
(Ord. 2002-15, Added, 11/19/2002)
Permits shall be issued for a specified time period, not to exceed five years. A permit may be issued for a period less than a year or may be stated to expire on a specific date. A user discharging after the expiration date of the permit shall be considered in violation of this chapter. It is the responsibility of the user to apply for a new discharge permit at least ninety days before the expiration date of their existing permit. The terms and conditions of the permit may be subject to modification and change by the city during the life of the permit, as limitations or requirements stipulated in this chapter are modified and changed. The user shall be informed of any proposed changes in user's permit at least thirty days prior to the effective date of change. Any changes or new conditions in the permit shall include a reasonable time schedule for compliance.
(Manual, Added, 11/19/2002; Ord. 2002-15, Add, 02/06/2003)
Wastewater discharge permits are issued to a specific user for a specific operation. A wastewater discharge permit shall not be assigned, transferred or sold to a new owner, new user, different premises or a new or changed operation without prior written approval of the director.
(Ord. 2002-15, Added, 11/19/2002)
A permit may be temporarily suspended at any time if it is the director's opinion that the continued discharge of the waste or water into the sewerage system would substantially jeopardize the ability of the treatment facilities or sewerage system to meet water quality requirements or would cause an unsafe condition to occur. In lieu of temporary suspension of permits, the director may impose such temporary restrictions, conditions or limitations upon the quantities, qualities and rates of discharge made thereunder as deemed necessary to assure that the receiving water quality requirements will not be violated or to alleviate the unsafe condition. Notice of the temporary suspension or the imposition of temporary restrictions, conditions or limitations shall be given in writing by the public works director to the permittee at least twenty-four hours prior to their effective date. Delivery of the notice to the permittee's place of business shall constitute delivery of notice to permittee.
(Ord. 2002-15, Added, 11/19/2002)
Any permittee who violates the following conditions of the permit or of this chapter, or applicable state and federal regulations, is subject to having this permit revoked:

Users in industrial categories subject to the categorical pretreatment standards development by the EPA under the Clean Water Act of 1977 (PL 95 217) 33 U.S.C. 1251 et seq. are required to achieve limitations based on best practical control technology (BPT) immediately and best available technology economically achievable (BAT) by July 1, 1983, in accordance with sections 301 and 304. New sources are required to comply with new source performance standards (NSPS) based on best available demonstrated control technology (BDT) for industrial users in terms of concentration and equivalent mass values. Users must comply with pretreatment standards promulgated pursuant to section 307 and the Federal Register 40 CFR Subchapter IV. Dilution of any discharge may not be used to comply with any pretreatment standards. Categorical industrial users must submit baseline monitoring reports, compliance schedule reports, ninety-day compliance reports, and periodic reports on continued compliance as required including identifying information per 40 CFR 403.12(1) and such reports must be signed by an authorized representative of the industrial user and meet certification requirements of 40 CFR 403.6(a)(2)(ii) and 403.12(b)(6) and be retained for a minimum of three years (or period of litigation, whichever is longer). The director of public works may issue standards more stringent than the federal standards if he/she determines that the limitations in the federal standards are not sufficient to:
A.
Protect the operation of the city's treatment facilities; or
B.
Comply with water quality standards, sludge disposal or effluent limitations specified in the city's National Pollutant Discharge Elimination System (NPDES) permit;
C.
Meet technically based local limits, which must be calculated per federal pretreatment program guidelines.
(Ord. 2002-15, Added, 11/19/2002)
A wastewater pretreatment system or device may be required by the director to treat flow prior to discharge to the sewer when it is necessary to restrict or prevent the discharge to the sewer of certain waste constituents not in compliance with section 14.20.020, "prohibited discharges," to distribute more equally over a longer time period any peak discharges of wastewaters or to accomplish any pretreatment result required by the director.
A.
All pretreatment systems or devices shall be approved and permitted by the director; but such approval shall not absolve the discharger of the responsibility of meeting any effluent limitation required by the director. All pretreatment systems judged by the director to require engineering design shall have plans prepared and signed by an engineer of suitable discipline licensed in the State of California.
B.
Normally, a gravity separation interceptor, equalizing tank, neutralization chamber and control manhole will be required, respectively, to remove prohibited settleable and floatable solids, to equalize wastewater streams varying greatly in quantity and/or quality, to neutralize low or high pH flow and to facilitate inspection, flow measurement and sampling.
(Ord. 2002-15, Added, 11/19/2002)
Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(Ord. 2002-15, Added, 11/19/2002)
A.
The director may require the user to construct and maintain, at the user's expense, monitoring facilities such as a control maintenance hole to allow inspection, sampling and flow measurement of the building sewer or internal storm drainage systems and may also require sampling or metering equipment to be provided, installed, operated and maintained at the user's expense. The monitoring facility should normally be situated on the user's premises, but the director may, when such a location would be impractical or cause undue hardship on the user or the city, allow the facility to be constructed in the public right-of-way and located so that it will not be obstructed by landscaping or parked vehicles.
B.
When the monitoring facility is inside the user's fence, there shall be accommodations to allow access for the director or designated representative.
C.
Plans and specifications for monitoring facilities shall be approved by the director and be in accordance with all applicable city construction standards and specifications. Construction shall be completed within sixty days following written notification by the city, unless a time extension is otherwise granted by the city.
(Ord. 2002-15, Added, 11/19/2002)
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this Chapter shall be determined in accordance with the latest edition of "standard methods for the examinations of water and wastewater," published by the American Public Health Association, and shall be determined at the monitoring facility provided, or upon suitable samples taken at said monitoring facility. In the event that no special facility has been required, the test shall be taken at the nearest downstream maintenance hole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property.
(Ord. 2002-15, Added, 11/19/2002)
In addition to the federally required reports described in section 14.20.120, the director may require that any high-strength user discharging, or proposing to discharge, wastewater into a sewerage system, file a periodic discharge report. The discharge report may include, but not be limited to, nature of process, volume, rates of flow, mass emission rate, temperature, pH, production quantities, hours of operation, number and classification of employees, chemicals and materials stored or used, or other information which relates to the generation of waste including characteristics in the wastewater discharge. Such reports shall also include the chemical characteristic and quantity of liquid or gaseous materials used annually as well as those stored on site, even though the latter may not normally be discharged. All reports are due fourteen days after the conclusion of monitoring or receipt of the laboratory analysis report and must be signed by an authorized representative of the industrial user. All such reports shall be retained for a period of three years (or period of litigation, whichever is longer), and shall be made available for inspection and copying by the city. In addition to discharge reports, the city may require information in the form of wastewater discharge permit applications and self-monitoring reports.
(Ord. 2002-15, Added, 11/19/2002)
Nothing contained in this Chapter shall be construed to limit any additional requirements that may be imposed by the county health officer, by the Regional Water Quality Control Board, Fish and Game, or by other governmental agencies having jurisdiction.
(Ord. 2002-15, Added, 11/19/2002)
Violation of any of the provisions of this Chapter is unlawful and an offense. Such violations shall be punished as provided by Chapter 21.01 of Title 21. In addition to any other remedies provided in this Chapter, any violation of the provisions of this Chapter may be enforced by civil action brought by the city pursuant to sections 21.01.060 and 21.01.080. In any such action, the City may seek any or all of the following remedies:
A.
Injunctive relief;
B.
Assessment against the violator for the costs of any investigation, inspection, or monitoring survey which led to the discovery of the violation, and for the reasonable costs incurred in preparing and prosecuting the legal action as a result of violations of this Chapter;
C.
Recovery for costs incurred in removing, correcting, terminating, or preventing adverse effects resulting or likely to result from the violation;
D.
Compensatory damages for loss or damage to the POTW and/or
E.
Such other relief as the court may authorize.
Any person who violates any provision of this Chapter, who discharges or causes pollution, or who violates any cease and desist order, state or national law or regulation, or any other order of the director shall be civilly liable to the city in a sum not to exceed twenty-five thousand dollars ($25,000.00) per violation per day. In addition, the city may require the user to pay any excess costs to the system for supplementary treatment systems, facilities, or operations needed as a result of allowing the entry of such discharges into the wastewater system. Remedies imposed pursuant to this section are in addition to and do not supersede or limit any and all other administrative, civil, or criminal remedies available at law.
