14.17.030 Declaration of policy.

It is declared to be the policy of the City to protect the health, welfare and safety of the residents thereof by constructing, operating and maintaining a system of sewers and liquid waste treatment and disposal facilities that service the homes and commercial and industrial establishments within the City and its environs, as required by State and Federal law. The following basic principles apply to wastewater that is discharged into the system:
(A) The highest and best use of the system is the collection, treatment and reclamation or disposal of domestic wastewater. The use of the system for industrial waste discharges is subject to regulation by the City;
(B) Industry is urged to seek procedures for the recovery and reuse of industrial waste discharges which will satisfy the limitations that are prescribed for industrial discharges, rather than the procedures that are designed solely to meet discharge limitations;
(C) The City is committed to a policy of wastewater renovation and reuse in order to provide an alternate source of water supply and to reduce the overall costs of wastewater treatment and disposal. The renovation of wastewater through wastewater treatment processes may necessitate more stringent quality requirements with respect to industrial waste discharges as the demand for reclaimed water increases. The optimum use of the City’s facilities may require the discharge of wastewaters during periods of low flow into the system in accordance with guidelines that are established by the City;
(D) Provisions are made in this Chapter to regulate industrial discharges, to comply with the State and Federal requirements and policies and to satisfy increasingly higher standards of treatment plant effluent quality and environmental considerations. This Chapter establishes quantity and quality limitations on wastewater discharges in situations in which such discharges may adversely affect the system or the quality of the effluent therefrom, or both. These limitations are intended to improve the quality of wastewater being received for treatment and to encourage water conservation by all of the users who are connected to the system. The intent of the City’s policy is to discourage an increase in the quantity (mass emission rate) of waste constituents that are discharged; and
(E) Methods of cost recovery are established in situations in which industrial discharges impose collection, treatment or disposal costs, or any combination of such costs, on the City which may not be fair and equitable to all users of the system.
(Ord. 3713 § 3, 1993: Ord. 3447 § 82, 1989)

14.17.035 Director--Powers and duties.

(A) The Director is authorized, empowered and directed to adopt such rules, regulations and standards as may be deemed by him to be reasonably necessary in order to protect the system and to control and regulate the proper use thereof; provided, however, that the terms and provisions of such rules and regulations shall be promulgated in a manner that is reasonably calculated to result in the uniform control of the system.
(B) The Director may classify dischargers by industrial categories and impose an industrial wastewater treatment surcharge that is based upon flow quality and the flow quantity, as provided for by this Chapter.
(C) Any time limit that is provided in any written notice from the Director or in any provision of this Chapter may be extended only by a written directive of the Director.
(D) The Director may perform work of an educational nature and may, for this purpose, cooperate with civic organizations, industries, water agencies, wastewater collection and treatment agencies and other public corporations.
(E) The Director shall have the responsibility of administering, implementing and enforcing all of the provisions of this Chapter. However, any power that is granted to, or duty that is imposed upon, the Director may be delegated by him to any other person who is in the employ of the City’s Department of Public Works and may be confirmed in writing by the City Council upon any other person or persons, whether or not he or they are in the employ of the City.
(Ord. 3713 § 4, 1993: Ord. 3447 §§ 89, 132, 1989)

14.17.040 City may restrict discharge.

If wastewater collection and treatment capacity is not available at the City’s wastewater treatment plant, the City may restrict discharge into the system until sufficient capacity can be made available. When it is requested to do so by a potential discharger who desires to locate new facilities within the service area of the system, the City may advise such discharger concerning the areas in which wastewater of the quantity and quality that it is expected to generate can be received by the system. The City may refuse immediate service to any new source that is located in an area in which the expected quantity or quality of wastewater is unacceptable in the system.
(Ord. 3713 § 5, 1993: Ord. 3447 § 85, 1989)

14.17.045 Users required to retain records.

A deposit in an amount to be determined by the Director as being sufficient to pay the estimated charges for use shall accompany the application for a temporary wastewater discharge permit, and such deposit shall be applied to the charges for the use of the system thereunder.
(F) Each temporary wastewater discharge permit shall be issued for a specific period, not to exceed two years. The terms and conditions of such permit may be subject to modification and change by the City during the period for which it was issued. Any change or new condition in such permit shall include a reasonable time schedule for compliance therewith.
(Ord. 3713 § 24, 1993: Ord. 3447 § 114, 1989)

14.17.195 Wastewater contribution permit--Users outside city boundaries.

Wastewater contribution permits for industrial users who are located outside of the corporate boundaries of the City but are tributary to the system will be issued by the City by way of a specific agreement. The Director will be authorized to inspect the facilities of each such industrial user who is issued a permit hereunder in order to determine its compliance with this Chapter, and the requirements of this Chapter apply to each such industrial user.
(Ord. 3447 § 115, 1989)

14.17.200 Pretreatment facilities.

(A) An industrial wastewater pretreatment facility or device may be required by the City to treat industrial flows prior to their discharge into the system whenever it is necessary to restrict or prevent the discharge to the system of certain waste constituents, to distribute more equally over a longer period any peak discharge of industrial wastewaters or to accomplish any pretreatment result that is required by the City. All such pretreatment facilities or devices shall be approved by the City before their use, but such approval shall not absolve the industrial user that owns or operates the same of the responsibility of meeting any industrial effluent limitation that is imposed by the City on such flows. In a special case, the City may require the construction of sewer lines by the industrial user in order to convey certain industrial wastes to a specific trunk sewer. All pretreatment facilities that are judged by the City to require engineering design shall have the plans therefor prepared and signed by an engineer of suitable discipline who is licensed in the State. Detailed plans that show the pretreatment facilities and operating procedures, including without limitation accidental discharge procedures, shall be submitted to the City for its review and approval before such plans and procedures are implemented. Such review and approval, however, shall not absolve the industrial user that owns or operates such facilities from the responsibility of modifying such facilities in the future as may be necessary in order to produce an effluent that is acceptable to the City under the provisions of this Chapter. No industrial user shall ever increase the use of water, or in any other manner attempt to dilute a discharge, as a partial or complete substitute for adequate methods for the reduction of pollutants to achieve compliance with this Chapter and such industrial user’s wastewater contribution permit.
(B) Normally a gravity separation interceptor, equalizing tank, neutralization chamber and control manhole shall be required, respectively, in order to remove prohibited settleable and floatable solids, to equalize wastewater streams which vary greatly in quantity or quality, or both, to neutralize low or high pH flows and to facilitate inspection, flow measurement and sampling. Floor drains from commercial or manufacturing buildings, warehouses or multiuse structures as required by the Director shall not discharge directly to the system but shall first discharge to a gravity separation interceptor.
(C) All domestic or sanitary wastewaters from restrooms, showers, drinking fountains and similar facilities shall be kept separate from all industrial wastewaters until the industrial wastewaters have passed through any required pretreatment facility or monitoring device if it is reasonably practical and deemed necessary by the City.
(D) If it is deemed necessary by the City for an industrial user, whether under permit or not, to install a pretreatment facility or device, the City shall place a time constraint on the final installation and operational date of such facility or device. If appropriate this constraint shall include a compliance schedule which indicates milestone dates for the design of the facility or device, final engineering approval, start of construction and start up date, and a compliance deadline. The industrial user shall submit regular progress reports to be received monthly as required by the City. The compliance schedule may be extended only as provided for by Section 14.17.290(A)(1) using the same procedures as noted therein for extension of a compliance schedule associated with a wastewater contribution permit.
(Ord. 3713 § 25, 1993: Ord. 3447 § 116, 1989)

14.17.205 Monitoring facilities.

(A) Any Class I industrial user, or any other industrial user, discharging wastewater under permit by the City or without such permit at the discretion of the Director, shall be required to install and maintain monitoring facilities in order to allow inspection, sampling or measurement, or any combination thereof, of the building sewer or plumbing systems and may also be required to provide, install and operate sampling or measuring, or both, equipment at such industrial user’s expense. Such facilities shall be normally situated on the industrial user’s premises but the Director may, in his discretion, allow monitoring facilities to be constructed elsewhere at the industrial user’s expense.
(B) Each industrial user who makes periodic measurements shall furnish and install, at its own cost and expense, at the sampling well or other appropriate location a calibrated flume, weir, flow meter or similar device that is approved by the City and is suitable to measure the industrial wastewater flow rate and total volume. A flow indicating, recording and totalizing register may also be required by the City. In lieu of such wastewater flow measurement, the City may accept records of water usage and adjust the flow volumes by suitable factors in order to determine the peak and average flow rates for a specific discharge.
(C) If two or more industrial users can discharge into a common side sewer, the Director may require the installation of a separate monitoring facility for each such user. Also, if, in the judgment of the Director, there is a significant difference in the constituents and characteristics of the wastewaters produced by the different operations of a single industrial user, the Director may require that separate monitoring facilities be installed for each separate discharge.
(D) If a monitoring facility is inside an industrial user’s fences, measures shall be taken in order to afford access to the facility by the personnel of the City, including without limitation such measures as a gate secured with a lock that is furnished by the City. There shall be ample operating area in or near such monitoring facility in order to allow accurate sampling and compositing of the samples for analysis. The industrial user shall assure that the access and the sampling and measuring equipment are maintained in a safe and proper operating condition at all times at no expense to the City.
(E) The monitoring facility, and the sampling and measuring equipment therein, shall be provided in accordance with the City’s design requirements and all of the applicable construction standards, safety devices and specifications. Construction shall be completed within ninety days following the industrial user’s receipt of written notification from the City to provide the same.
(F) The monitoring facility shall be provided with a security closure that can be locked during the sampling or monitoring with a lock that will be provided by the City.
(G) Unrestricted access to the monitoring facility shall be available to authorized personnel of the City at all times.
(Ord. 3713 § 26, 1993: Ord. 3447 § 117, 1989)

14.17.210 Sand, grease and oil traps.

Traps for sand, grease and oil shall be provided in accordance with the following requirements:
(A) Each restaurant or other establishment that discharges grease wastes which, under the conditions that exist in the downstream sewers, could cause or threaten to cause a stoppage or a grease accumulation shall be required to install an approved grease trap and oil interceptor and regularly to maintain it in such a manner as to prevent excessive discharges of grease and oil into the system. Each grease trap and oil interceptor shall be easily accessible for inspection by the City. An exception to the requirement of installing a grease trap and oil interceptor may be granted on a case-by-case basis by the Director, taking into account the following items:
(1) The size of restaurant;
(2) The number of meals served per day;
(3) The available seating capacity; and
(4) The dish washing and garbage disposal facilities that are available.
(B) Each new car wash, vehicle service station and garage which has facilities for the washing of vehicles shall install an appropriate sand and oil interceptor of a size and design that is approved by the City. Each such establishment that was in existence prior to the effective date of this Chapter shall install an appropriate sand and oil interceptor if, in the opinion of the Director, such establishment has the potential of contributing noncompatible material to the system.
(C) A trap or interceptor that was legally and properly installed at a restaurant or similar establishment, car wash, vehicle service station or garage prior to the effective date of this Chapter shall be acceptable as an alternative to the trap or interceptor that is specified in subsection (A) or (B) of this Section if such trap or interceptor is effective in removing grease and oil or sand and oil, as the case may be, and is designed and installed in such a manner that it can be inspected and properly maintained. If the City determines that a trap or interceptor is incapable of retaining adequately the grease and oil or the sand and oil, as the case may be, in the wastewater flow from a restaurant or similar establishment, car wash, vehicle service station or garage, the City shall issue a written notice that requires the operator of such establishment to install an adequate trap or interceptor within sixty days.
(D) The City may maintain an information file, available for public inspection, of acceptable designs of grease, sand and oil traps and interceptors. The installation of a trap or interceptor of a design that is shown in such file, or of any design that meets the requirements that are set forth in this Section or any recommendation or requirement that is made by the City shall not impute any liability to the City as a result of such trap’s or interceptor’s failure adequately to perform under the actual conditions of its use. Such installation shall not relieve the owner or proprietor of such establishment of the responsibility to keep grease and oil or sand and oil, as the case may be, from entering the system. If a trap, interceptor or other pretreatment facility is not adequate under the actual conditions of its use, a new trap, interceptor or pretreatment facility shall be constructed which is effective in accomplishing the intended purpose.
(E) Any grease trap and oil interceptor or sand and oil interceptor that is required by this Section shall be readily accessible for inspection by the authorized personnel of the City and shall be properly maintained to ensure that accumulations of grease and oil or sand and oil, as the case may be, do not impair the efficiency of the trap or interceptor or are not discharged with the effluent, or both. Each establishment that is required to use and maintain a grease trap and oil interceptor or a sand and oil interceptor shall keep a record of every time the trap or interceptor is cleaned. This record shall include the date, the name of the pumper or person who cleaned the trap or interceptor and the site at which the waste was disposed of and may be reviewed by the City in its discretion. A trap or interceptor shall not be considered properly maintained if accumulations of grease and oil or sand and oil, as the case may be, total more than twenty-five percent of the operative fluid capacity. The City will endeavor to inspect all grease traps and oil interceptors and sand and oil interceptors periodically. If it is found that a trap or interceptor in any establishment is improperly maintained or adequate records with respect thereto are not being kept, a warning will be issued to the operator of such establishment. If, on any subsequent inspection, it is found that any one of the aforesaid conditions continues to exist, a penalty fee in an amount that is established by the City will be levied against the operator of the establishment.
(Ord. 3713 § 27, 1993: Ord. 3447 § 118, 1989)

14.17.215 Containment of uncontrolled discharges.

(A) Upon its receipt of a written notification from the Director, each user shall provide facilities for the containment of uncontrolled discharges of prohibited material or other substances that are regulated by this Chapter. Facilities to contain such discharges shall be provided and maintained at the user’s sole cost and expense. Each user who is so notified shall provide a detailed slug prevention and control plan, including without limitation plans for the facility and operating procedures, to the Director for his review and approval. This slug prevention and control plan shall contain, but is not limited to, the following elements:
(1) Description of discharge, including nonroutine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for promptly notifying the City of slug discharges, including any discharge that would violate a specific prohibition contained in 40 CFR 403.5(b) or this Chapter, including procedures for follow-up written notification within five days;
(4) Procedures to prevent accidental spills, including as necessary, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents);
(5) Procedures and practices for responding to accidental spills including as necessary measures and equipment for emergency response and follow-up practices to minimize the damage suffered by the City’s wastewater treatment plant or the environment.
(B) Such plans and procedures must be approved before the installation or the commencement of the construction of the facility. The construction of the facility shall be completed within the period that is designated by the Director in the notification to the user of his approval thereof. The review and approval of a slug prevention and control plan and operating procedures shall not absolve the user of the responsibility of modifying its facility as may be necessary in order to satisfy the requirements of this Chapter.
(Ord. 3713 § 28, 1993: Ord. 3447 § 119, 1989)

14.17.220 Flammable substances.

(A) Upon its receipt of a written notification from the Director, each user of flammable substances and each user who is subject to uncontrolled discharges of flammable substances may be required to install, operate and maintain a combustible gas monitoring system and facility to divert the entire wastewater flow to a holding tank whenever the combustible gas level at its establishment is greater than twenty percent of the lower explosive limit. Such system and facility shall be provided and maintained at the user’s sole cost and expense. Each user who is so notified shall provide detailed gas monitoring and wastewater diversion plans, including without limitation plans for the facility and operating procedures, to the Director for his review and approval. Such plans shall include procedures for notification of City personnel in the event of uncontrolled or emergency discharge of flammable substances, a complete description of all such substances stored or used at the facility and procedures to be taken to prevent an adverse impact on the wastewater treatment plant or the collection system if such an event were to occur. The plans must also contain emergency procedures for containment of spills of flammable materials within the facility to include specific procedures to be taken by facility personnel, emergency telephone numbers and contacts, and any other procedures as required to prevent the spill from impacting the wastewater treatment plant or the collection system.
(B) Such plans and procedures must be approved before the installation or the commencement of the construction of such system and facility. At the minimum, the monitoring system and facility must be installed in a field location and have an indicator, automatic continuous recorder, adjustable two-stage alarm system, calibration for methane detection and a means for diverting the flow to a holding tank; provided, however, that the Director, in his sole discretion, may waive any of these requirements by way of a written notice to the user. The installation or construction of such system and facility shall be completed within a period that is designated by the Director in the notification to the user of his approval thereof. The review and approval of gas monitoring and wastewater diversion plans shall not absolve the user of the responsibility of satisfying the requirements of this Chapter.
(Ord. 3713 § 29, 1993: Ord. 3447 § 120, 1989)

14.17.225 Wastewater analyses.

Periodic measurements of flow rates, flow volumes and wastewater characteristics for use in determining a user’s compliance with any limitation or requirement that is specified in its wastewater contribution permit, if any, or in this Chapter shall be made at the times and in the manner that is prescribed by the City. The City shall establish, on an annual basis, the wastewater analyses to be performed by the user and shall notify the user at least sixty days prior to the deadline for the submission of any required compliance monitoring report. All sampling, analyses and flow measurements of industrial or liquid wastes shall be performed by an independent laboratory that is approved by the City, by a laboratory of the user that is approved by the City or by the personnel of the City. If such sampling, analyses and flow measurements are performed by an independent laboratory, the costs thereof shall be paid by the user, and, if the same are performed by the personnel of the City, a charge that is sufficient to defray the actual expenses of the City for the personnel, space, equipment and supplies, as the same are determined by the City, shall be paid by the user.
(Ord. 3447 § 121, 1989)

14.17.230 Periodic measurement for surcharge determination.

(A) Periodic measurements of flow rates, flow volumes and wastewater characteristics for use in determining the appropriate industrial wastewater treatment surcharge, and such measurements of other constituents that are believed by the Director to be necessary for such purpose, shall be made by each user unless any such user is specifically relieved of such obligation in writing by the Director. All sampling, analyses and flow measurements of industrial wastewaters shall be performed by an independent laboratory that is approved by the City, by a laboratory of the user that is approved by the City or by the personnel of the City. If such sampling, analyses and flow measurements are performed by an independent laboratory, the costs thereof shall be paid by the user, and, if the same are performed by the personnel of the City, a charge that is sufficient to defray the actual expenses of the City for the personnel, space, equipment and supplies, as the same are determined by the City, shall be paid by the user.
(B) Any user may be required by the Director, by its wastewater contribution permit, if any, or otherwise, to engage in periodic monitoring or sampling, or both, of its discharge. If a user is required to monitor or sample its discharge, the user shall notify the City by telephone at least forty-eight hours in advance of any monitoring or sampling that is to be performed. Such notification shall include the date, time and location of the proposed monitoring or sampling, and the monitoring or sampling shall be carried out during a period of normal business operations. Prior to the commencement of any monitoring or sampling, the Director may request that the user furnish the City with a split sample and all supporting data (i.e., methodology, flow measuring data, strip chart recordings and other pertinent information). The City reserves the right to refuse any data that are developed from its monitoring or sampling activity if the user has failed to comply with the prenotification procedure.
(C) Each user shall submit to the City, sworn to by the user under the penalties for perjury, its monitoring and sampling report or other requested data.
(Ord. 3447 § 122, 1989)

14.17.235 Sampling procedures subject to inspection.

(A) The sampling, analysis and flow measurement procedures, equipment and results shall be subject at all reasonable times to inspection by the City. Sampling and flow measurement facilities shall be constructed and located in such a manner as will provide safe access to the authorized personnel of the City.
(B) Each user who is required by the City to make periodic measurements of its wastewater flows and constituents shall make at least the minimum number of such measurements required. The minimum requirement for such periodic measurements shall be at least one twenty-four-hour measurement per year, and representative samples of the wastewater shall be obtained at least once per hour during the twenty-four-hour period and shall be properly refrigerated, composited according to measured flow rates during the twenty-four hours and analyzed for the specified wastewater constituents. If the sampling protocol, as established in 40 CFR 403.12, prohibits the use of composite samples, a grab sample shall be taken during the twenty-four-hour period. Each user who is required to obtain only a few samples per year shall take such samples during the periods of the highest wastewater flow and wastewater constituent discharges. An industrial plant that has a large fluctuation in quantity or quality of wastewater may be required to provide continuous sampling and analyses for every working day, if it is required to do so by the City. A user may also be required to install and maintain in proper order automatic flow-proportional sampling equipment or automatic analysis and recording equipment, or both.
(C) Measurements to verify the quantities of waste flows and waste constituents that are reported by each user will be conducted on a random basis by the personnel of the City.

(A) The determination or estimation of suspended solids or other components that are contained in wastewater discharges shall be made in accordance with one of the following methods:
(1) Sampling and analysis by the personnel of the City;
(2) Sampling and analysis by the personnel or a laboratory of the user who are or is approved by the City; or
(3) Estimates that are determined by a study of the user’s waste producing operations that lead to the discharge and are approved by the Director.
(B) Each user shall have the option of selecting which of the methods that are described in Subsection (A) of this Section will be used; provided, however, that such method must be proposed by the user and approved by the City before the beginning of the period during which such sampling or estimate is to be made, and the same method must be continued throughout such period. In the event that no method is selected and approved, the method that is described in paragraph (1) of Subsection (A) will be used, and the appropriate fees, as established by the City, shall be paid by the user. Additionally, in the event that either of the methods that are described in paragraphs (2) and (3) of Subsection (A) is selected and approved, the City may, by appropriate sampling and analysis, determine the accuracy of the results that are so obtained, and if the method that is described in paragraph (2) is selected and approved, the user shall, upon the request of the City, prepare and submit a certified statement with respect to the results that are so obtained during the period in question.
(Ord. 3713 § 32, 1993: Ord. 3447 § 125, 1989)

14.17.250 Measurement of total flow of waste.

The measurement of total flow of wastewater shall be made by the City by means of a metering device that is approved by the City and is purchased, installed and maintained at the expense of the user, by an estimate that is based upon total water which is used in the area that is occupied, or by other means that is acceptable to the City and to the user. The user shall have the option of selecting whether the measurement shall be made by meter, by estimate or by other means; provided, however, that the method of estimating or other means must first be approved by the City.
(Ord. 3713 § 33, 1993: Ord. 3447 § 126, 1989)

14.17.255 Determination of peak flow rate.

(A) The determination of the peak flow rate shall be made by means of an effluent meter that is approved by the City and is purchased, installed and maintained at the expense of the user or by field measurements that are made by the City in accordance with the method that is provided in subsection (B) of this Section. The user shall have the option of selecting the method of determination to be used; provided, however, that, in the event the field measurements method is selected, the user must bear all of the expenses that are incurred by the City in carrying out the field measurements.
(B) In the absence of actual peak flow rate data with respect to any user, peak flow rate may be computed for such user in a manner that is established by the City, and the user whose peak flow rate is so computed shall certify to the City that the flow use that is metered in order to compute the peak flow rate was from normal operations and not the result of any extraordinary condition.

14.17.260 Excess discharge--Amendment of permit.

(A) Should flow measurements or other investigations demonstrate that an industrial user is discharging at a flow rate, or in a quantity of flow, biochemical oxygen demand, phosphorus or suspended solids, that is significantly in excess of that which is stated in its wastewater contribution permit or in excess of the quantities that are reported to the City by such industrial user, and upon which its industrial wastewater treatment surcharge is based, such industrial user shall apply for an amended wastewater contribution permit and shall be assessed for all delinquent charges, together with any penalty and interest, as the same are provided for in LVMC 14.17.340, 14.17.345(A) and 14.17.350, inclusive, and 14.17.360. However, before such charges shall be assessed, at least two additional twenty-four-hour samples and flow measurements shall be obtained by the City, and all of the costs of such sampling and analyses shall be paid by such industrial user.
(B) For the purpose of establishing the correct treatment surcharge, the data that are obtained in the samplings that are provided for in Subsection (A)
of this Section, together with any other relevant information that is obtained by the City or submitted by the industrial user, shall be used by the City in determining the quantity parameters that are to be used in the surcharge formula. An industrial user who is found to be discharging at a flow rate, or in a quantity of flow, biochemical oxygen demand, phosphorus or suspended solids, that is significantly in excess of that which is stated in its wastewater contribution permit or in excess of the quantities that are reported to the City by such industrial user shall, in the absence of other evidence, be presumed to have been discharging at the determined parameter values at all times during the preceding three years or at all times subsequent to the previous verification of quantity parameters by the City, whichever period is shorter.
