County Sanitation Districts of Los Angeles County WASTEWATER ORDINANCE


PART 1 - ADMINISTRATION


SECTION 100 - AUTHORIZATION

This Ordinance is enacted pursuant to authority contained in the County Sanitation District Act, California Health and Safety Code, Sections 4700 through 4859 and exercises authority conferred by law including but not limited to Health and Safety Code, Sections 5400 through 5474, and California Government Code, Sections 54725 through 54740.

SECTION 101 - PURPOSE AND SHORT TITLE

The purpose of this Ordinance is to protect the environment and public health; to provide for the maximum possible beneficial public use of the Districts' sewerage facilities through adequate regulation of sewer construction, sewer use and industrial wastewater discharges; to provide for equitable distribution of the Districts' costs; and to provide procedures for complying with requirements placed upon the Districts by other regulatory agencies. This Ordinance shall be known as the Wastewater Ordinance and may be cited as such.

SECTION 102 - SCOPE

This Ordinance shall be interpreted in accordance with the definitions set forth in Appendix A, hereto, which Appendix is hereby incorporated as a part of this Ordinance.

The provisions of this Ordinance shall apply to all direct or indirect discharges, including the discharge of all wastewater, to any part of the sewerage systems of the Districts, or to other sewerage systems tributary to the Districts' sewerage system. The provisions of this Ordinance shall also apply to wastewater originating outside the territorial boundaries of the Districts or outside the boundaries of Los Angeles County if such wastewater eventually enters the Districts' sewerage system. This Ordinance among other things regulates sewer construction and provides for the approval of plans for sewer construction and implements federal and state pollution control regulations. This Ordinance provides for the issuance of permits, including Permits for Industrial Wastewater Discharge, prohibits the discharge of certain wastes and regulates the quantity and quality of other waste discharges. This Ordinance imposes wastewater pretreatment requirements upon waste dischargers and provides for the regulation of the degree of such pretreatment. This Ordinance provides for the filing of Wastewater Treatment Surcharge Statements, imposes fees and charges and provides for the distribution of revenue. Violations of this Ordinance are subject to criminal fines and penalties, civil liabilities and other penalties in accordance with law.

SECTION 103 - LIQUID WASTE DISPOSAL POLICY

The Districts construct, operate and maintain trunk sewers and wastewater treatment and disposal facilities serving residential, industrial, institutional and commercial users throughout a major portion of Los Angeles County. Local wastewater collection systems (lateral sewers) are constructed, operated and maintained by other public agencies, including the County of Los Angeles and various cities. Such systems are typically tributary to and discharge into the Districts' sewerage systems. The following policies apply to all wastewater discharges within the Districts' boundaries and to other discharges that are tributary to the Districts' facilities.

Wastewater originating within the Districts' boundaries will generally be accepted into the Districts' sewerage systems, provided the wastewater will not,directly or indirectly,(1) damage structures; (2) create nuisances such as odors; (3) threaten public health; (4) impose excessive collection, treatment or disposal costs on the Districts; (5) interfere with wastewater treatment or residue disposal processes; (6) violate quality and pretreatment requirements set by the Districts or federal or state agencies; (7) detrimentally affect the environment or (8) cause the Districts to violate any terms or conditions of their facilities' permits or any other waste discharge or air quality requirements.

The highest and best use of the Districts' sewerage systems is the conveyance, treatment and disposal of domestic wastewater. The use of the Districts' sewerage systems for conveyance, treatment and disposal of industrial wastewater is subject to additional regulation by the Districts.

The use of the Districts' sewerage systems for disposal of contaminated or uncontaminated rainwater, groundwater or stormwater will be permitted by prior approval of the Chief Engineer only in those limited situations provided for in Section 305 of this Ordinance. Approval of any such use will be temporary in nature and may be revoked at any time by the Chief Engineer.

The Districts' sewerage systems must meet requirements imposed by the local, state and federal governments. Such regulations require the Districts to report violations of applicable waste discharge regulations which are discovered by the Districts in the course of their monitoring, inspection or other activities. Any fines or penalties imposed by another governmental agency on the Districts for a condition of noncompliance caused by a wastewater discharger shall be considered damages to the Districts and shall subject the person or persons causing the noncompliance to be subject to the provisions of Section 417 of this Ordinance.

The Districts have adopted a policy of wastewater reclamation and reuse in order to provide an alternate source of water supply and to reduce overall costs of wastewater treatment and disposal. The reclamation of wastewater through secondary and tertiary wastewater treatment processes may necessitate the imposition of quality requirements on industrial wastewater dischargers which are more stringent than those imposed by other government agencies.

To comply with local, state and federal requirements and to meet increasingly higher quality standards for treatment plant effluent, air emissions and residue, provisions are made in this Ordinance for the regulation of industrial wastewater discharges. This Ordinance establishes quantity and quality limitations on industrial wastewater discharges which may adversely affect the Districts' sewerage systems or the quality of treatment plant effluent, air emissions and residue. Methods of cost recovery from industrial wastewater dischargers are also established.

Recovery, reuse and waste minimization procedures established by industrial wastewater dischargers to meet the limitations set on their discharges will be preferred by the Districts over those procedures designed solely to meet wastewater discharge limitations.

In order to provide for the optimum use of the Districts' facilities, the Chief Engineer shall establish conditions of discharge which may include the rerouting of certain wastewaters to alternate sewers or treatment plants. The Chief Engineer may also require that certain industrial wastewaters be discharged during specified periods, such as low flow, in the Districts' sewerage systems.

SECTION 104 - SUPERSEDING PREVIOUS REGULATIONS

This Wastewater Ordinance, as amended July 1, 1998, shall supersede all previous regulations and policies of the Districts governing items covered in this Ordinance. Specifically, the provisions of this Ordinance shall supersede the Districts' "Policy Governing Use of District Trunk Sewers" dated December 6, 1961, and shall amend the Districts' "An Ordinance Regulating Sewer Construction, Sewer Use and Industrial Wastewater Discharges," dated April 1, 1972 , and as amended July 1, 1975, July 1, 1980, July 1, 1983, and November 1, 1989.


PART II - GENERAL PROVISIONS

SECTION 201 - ADMINISTRATION

Except as otherwise provided herein, the Chief Engineer shall administer, implement and enforce the provisions of this Ordinance. Any powers granted to or duties imposed upon the Chief Engineer may be delegated by the Chief Engineer to persons acting in the beneficial interest of or in the employ of the Districts.

SECTION 202 - PENALTY FOR VIOLATION AND CIVIL LIABILITY

Every person violating any provision of this Ordinance, including the failure to pay any fees, charges or surcharges imposed hereby, or any condition or limitation of a permit or plan approval issued pursuant thereto, is guilty of a misdemeanor, and upon conviction is punishable as provided by law. Each day during which any violation continues shall constitute a separate offense. The Chief Engineer is hereby authorized to seek, through the office of the District Attorney of Los Angeles County or other appropriate authority, prosecution of criminal charges against any person violating any provision of this Ordinance. Violations of discharge limitations established under this Ordinance may also be violations of state and federal environmental laws which may be punishable as felonies and which may also carry substantial fines and penalties.

In addition, any person who violates any provision of this Ordinance or any term or condition of any permit issued pursuant to this Ordinance or plan approval which prohibits or limits the discharge of any waste or imposes any pretreatment requirement shall be civilly liable to the Districts in the maximum sum provided by law for each day in which such violation occurs.

District No. 2 is hereby delegated the sole authority to, and by action of its Board of Directors may, elect to have any fees or charges prescribed by this Ordinance collected on the tax roll, and may, as provided by law, impose liens on property to collect any fees and charges which have become delinquent. District No. 2 is further delegated the sole authority to commence civil actions to enforce the provisions of this Ordinance and to recover any sums due hereunder and may further delegate such portions of that authority to the Chief Engineer as the Board of Directors of District No. 2 may deem appropriate. District No. 2 may agree to submit such actions to binding arbitration in those instances in which the Board determines that it is in the best interest of the Districts to do so.

SECTION 203 - VALIDITY

If any provision of this Ordinance or the application thereof to any person or circumstances is held invalid, the remainder of the Ordinance and the application of such provisions to other persons or circumstances shall not be affected thereby.

SECTION 204 - NOTICE

Unless otherwise provided herein, any notice required to be given to the Chief Engineer under this Ordinance shall be in writing and served in person or by first-class, registered or certified mail. If served by mail, the notice shall be sent to the last address known to the Chief Engineer. Where the address is unknown, service may be made upon the owner of record of the property upon which the alleged violation occurred.

Notice shall be deemed to have been given at the time of deposit, postage prepaid, in a facility regularly serviced by the United States Postal Service.

SECTION 205 - TIME LIMITS

Any time limit provided in any written notice or in any provision of this Ordinance may be extended only by the Chief Engineer in writing.

SECTION 206 - INSPECTORS AND MONITORING PERSONNEL

The Chief Engineer shall provide adequate identification for all Districts' inspectors, monitoring personnel, and other authorized personnel and these persons shall, when so requested, identify themselves when entering any property for inspection or sampling purposes, or when inspecting the work of any contractor.

Authorized personnel of the Districts may inspect and monitor any facility or industrial process that is involved directly or indirectly with any discharge to the Districts' sewerage systems. These facilities shall include but not be limited to sewers; wastewater pumping plants; pollution control plants; industrial wastewater generation, conveyance and pretreatment facilities, devices and connection sewers; wastewater monitoring facilities or stations; and all similar or related sewerage facilities. Inspections may be made to determine whether such facilities are maintained and operated properly, to verify that the discharger is in compliance with a cease and desist order, and to determine whether the discharger is otherwise in compliance with the provisions of this Ordinance.

Authorized personnel of the Districts shall be provided immediate access to all of the above facilities or to other facilities directly or indirectly connected to the Districts' sewerage systems any time wastewater is being discharged to the Districts' sewerage system, and any time the discharger's facility is open or operating, and any other reasonable times including, but not limited to, emergency situations. A condition for the issuance of any industrial wastewater discharge permit described in Sections 401 and 402 of this Ordinance and for the continued use of the Districts' sewerage system shall be that the discharger expressly consents to inspection of the discharger's facility and industrial processes at reasonable times by Districts' personnel or representatives. Inspections of other facilities for which no permit has been applied or issued may be made pursuant to the procedures set forth in Title 13 (commencing with Section 1822.50) of Part 3 of the Code of Civil Procedure. However, those procedures need not be followed in the event of an emergency affecting public health and safety, or if the discharger consents.

Access to wastewater monitoring facilities or stations, which are required under Section 414 of this Ordinance, shall be granted immediately upon request during any time the discharger's plant is open, any time wastewater is being discharged to the Districts' sewerage system, and any other reasonable time. Any permanent or temporary obstruction to the safe and easy access to the sewerage facility to be inspected shall promptly be removed by the discharger or property owner at the written or verbal request of the Chief Engineer and shall not be replaced. Classes of dischargers whose industrial wastewaters have been determined by the Chief Engineer to present identifiable hazards to the Districts' sewerage systems, and those individual dischargers whose security procedures or plant configurations restrict or delay access shall provide an approved, secured monitoring facility which is directly accessible to Districts' personnel without having to pass through other secured property of the discharger. The costs of providing facilities with such access shall be borne by the discharger and not by the Districts.

No person shall interfere with, delay, resist or refuse entrance to authorized Districts' personnel attempting to inspect any facility involved directly or indirectly with a discharge of wastewater to the Districts' sewerage system.

SECTION 207 - DELETED

SECTION 208 - RECORDING OF FEES AND CHARGES

The Chief Engineer shall keep an accurate account of all fees and charges received under this Ordinance, containing the names and addresses of the persons on whose account the fees and charges were paid, the date and amount thereof, and the purpose for which charges were paid. Such records shall be retained for at least that amount of time as provided by law.

SECTION 209 - ESTIMATED QUANTITIES AND VALUES

Unless otherwise provided herein, whenever the fees and charges required by this Ordinance are based on estimated values or estimated quantities, the Chief Engineer shall make such determinations in accordance with generally accepted engineering estimating practices.

SECTION 210 - COMPLIANCE WITH STATE AND FEDERAL REGULATIONS

The Chief Engineer shall establish standards for wastewaters discharged into the Districts' sewerage system or systems tributary thereto in accordance with state law and federal regulations, as they are promulgated from time to time. Violations of such standards shall constitute violations of this Ordinance.

SECTION 211 - APPROVAL OF PLANS AND ISSUANCE OF PERMITS

The Chief Engineer shall approve plans for sewerage construction, issue a Permit for Industrial Wastewater Discharge or any other permit under this Ordinance if the proposed sewerage construction, sewer connection, industrial wastewater discharge or other procedure conforms to the requirements of this Ordinance.

All required fees and charges shall be paid before approval of plans or issuance of a permit. Neither the approval of plans nor issuance of a permit, nor the absence thereof, shall relieve the discharger of any duty imposed by this Ordinance.

SECTION 212 - DISTRIBUTION OF REVENUE

Except as otherwise provided herein, all fees and charges payable under the provisions of this Ordinance shall be paid to the County Sanitation Districts of Los Angeles County and any revenue derived pursuant to this Ordinance shall be allocated as follows:

  • Any revenue derived from any source within an individual District other than a Joint Outfall District shall be credited to that District.
  • Any revenue derived from any source within the Joint Outfall Districts shall be distributed as prescribed in the Joint Outfall Agreement to which all Joint Outfall Districts are signatory. In the absence of such agreement, revenue shall be distributed as described in (A) above.

SECTION 213 - RECONSIDERATION AND APPEAL PROCEDURES

Any permit applicant, permit holder or wastewater discharger adversely affected by any decision, action or determination made by or on behalf of the Districts by the Chief Engineer in interpreting or implementing the provisions of this Ordinance or any permit issued hereunder, may file with the Districts a written request for reconsideration. Such requests shall be acted upon only if received within 45 days from the date of occurrence of the action in dispute. Requests for reconsideration shall be acted upon by the Chief Engineer within 45 days from the date of receipt. If the Chief Engineer fails to act within 45 days, the request shall be deemed to be denied. Persons requesting reconsideration shall promptly furnish all additional information and produce all additional documents requested by the Chief Engineer which are relevant to the subject matter of the request for reconsideration. Failure to promptly furnish all such information and documents shall be grounds for a denial of the request for reconsideration.

If the ruling made by the Chief Engineer is unsatisfactory to the person requesting reconsideration, the person may file an appeal with the Board of Directors of District No. 2. Any such appeal must be made in writing and filed within 45 days after notice of the action taken by the Chief Engineer. If the request is denied without action by the Chief Engineer, the person making the request must file any appeal within 90 days from the date the request for reconsideration was made. All appeals shall be filed with the Secretary of the Board of Directors of District No. 2.

The written appeal shall state all the pertinent aspects of the matter, and shall be accompanied by a fee of Five Hundred Dollars ($500.00) which shall be refunded if the appeal is sustained. The Board of Directors of District No. 2 may conduct a hearing on the appeal or may designate as a hearing examiner either one or more of its members or a third party who is neither an officer nor an employee of the Districts and who is found by the Board to possess special expertise in the matter at issue. The hearing examiner or examiners shall conduct a hearing on any appeal filed pursuant to this section and shall afford to the discharger the opportunity to appear personally or through counsel, to cross-examine witnesses and present evidence. Notice of the hearing shall be given in accordance with Section 204 at least fifteen days prior to the date of hearing. The hearing examiner or examiners shall submit a written report and recommendations to the Board together with a brief summary of the evidence considered and the conclusions reached with respect to this evidence.

The Board of Directors of District No. 2, after considering the evidence presented at a hearing before the full Board or report submitted to it by the hearing examiner, shall adopt findings supported by the evidence and shall make its decision and issue its order. The Board may adopt, reject or modify the report of the hearing examiner in whole or in part.

No decision, action, or determination of the Chief Engineer shall be stayed by any appeal procedure authorized by this section.

SECTION 214 - PAYMENT OF CHARGES AND DELINQUENT CHARGES

Wastewater treatment surcharges shall be determined in accordance with Section 409 of self-monitoring procedures performed by the industrial discharger pursuant to Section 414 and reported to the Districts as required by Section 411. Except as hereinafter provided, each industrial discharger shall make estimated surcharge payments to the Districts. Payments shall be due and payable on September 30, December 31, March 31, and August 15 of each year. Such payments shall be delinquent if not paid on said dates and collectively shall be in such amounts as shall equal the total surcharge payable as determined in accordance with procedures established by the Chief Engineer. The payment due August 15 of each year shall be equal the total wastewater treatment surcharge due for the preceding fiscal year less the sum of the prepayments due and made on September 30, December 31, and March 31 of the preceding fiscal year. In the event the sum of the prepayments exceeds the annual wastewater treatment surcharge due, the overpayment shall be refunded upon verification by the Districts. Wastewater treatment surcharges found to be due after audit shall bear interest from August 15 following the end of the fiscal year for which such surcharges accrued.

All other fees and charges imposed under the provisions of this Ordinance are due and payable upon serving a notice of charges. Any notice of charges shall be served by first-class mail or such other procedure as will reasonably assure receipt. Unpaid charges shall become delinquent 45 days after mailing or personally serving the notice of charges.

A basic penalty of one percent of the original unpaid amount shall be added to any fee or charge or wastewater surcharge for each day the charge is delinquent. This basic penalty shall not exceed ten percent. Additional penalties and interest shall accrue on the total of all delinquent fees, charges or wastewater surcharges and the basic penalty, at three percent over the prime interest rate in effect at the beginning of the fiscal year during which the charges were initially due, not to exceed the maximum allowed by law.

SECTION 215 - FAILURE TO FILE FORMS

Any person failing to file any form, statement, or permit application, or to submit plans or other documents or to provide information required by this Ordinance or by the Chief Engineer pursuant to authority conferred by this Ordinance shall be in violation of this Ordinance and shall be subject to the penalties and liabilities provided for in Section 202.

SECTION 216 - DAMAGE TO DISTRICTS' FACILITIES OR EQUIPMENT

Any unauthorized entering, breaking, damaging, destroying, uncovering, defacing or tampering with any temporary or permanent structure, equipment or appurtenance which is owned by the Districts or a part of the Districts' sewerage systems shall be a violation of this Ordinance.

SECTION 217 - EFFECTIVE DATE OF ORDINANCE

The effective date of this Ordinance is April 1, 1972; the effective date of the first amended Ordinance is July 1, 1975; the effective date of the second amended Ordinance is July 1, 1980; the effective date of the third amended Ordinance is July 1, 1983; the effective date of the fourth amended Ordinance is November 1, 1989; the effective date of the fifth amended Ordinance is July 1, 1998.

SECTION 218 - EFFECTIVE DATE OF WASTEWATER TREATMENT SURCHARGE

Charges made under Section 409 shall begin to accrue on July 1, 1972 and shall become payable thereafter as provided in this Ordinance.

PART III - SEWERAGE CONSTRUCTION AND SEWER USE

SECTION 301 - APPROVAL OF PLANS FOR SEWERAGE CONSTRUCTION

No person, other than employees of the Districts, persons contracting to do work for the Districts, or maintenance workers of the local sewering agency, shall construct or cause to be constructed, or alter or cause to be altered, any public sewer, lateral sewer, house connection or industrial connection sewer over six (6) inches in diameter, wastewater pumping plant, wastewater treatment plant, or other sewerage facility within the Districts where existing or proposed wastewater flows will discharge directly or indirectly to facilities of the Districts without first obtaining approval of sewerage construction plans from the Chief Engineer.

Persons wishing to make a sewer connection to the Districts' system may be required to pay a connection fee for sewerage system capacity. The Connection Fee Ordinance for the Sanitation District in which the sewer connection is proposed should be reviewed for specific requirements.

The applicant shall submit to the Chief Engineer for approval, construction plans and such specifications and other details as required to describe fully a proposed sewerage facility. The plans shall have been prepared under the supervision of and shall be signed by a civil, chemical or structural engineer registered in the State of California, or a registered engineer of other suitable discipline as determined by the Chief Engineer.

Approval of the plans by the city or by the county department that has jurisdiction over the local sewering system in the area in which the sewerage facility is to be located, shall be obtained before approval of plans by the Chief Engineer. Two (2) complete copies of the sewerage facility plans shall be furnished to the Chief Engineer for review and approval prior to any facility construction. Any revisions to approved plans shall be submitted for approval as described above.

Plans for sewerage construction for any facility which will convey industrial wastewater will not be approved by the Chief Engineer unless the discharger has first obtained a Districts' Permit for Industrial Wastewater Discharge or the discharger has received written permission from the Chief Engineer after agreeing not to discharge industrial wastewaters until a Districts' Permit for Industrial Wastewater Discharge is obtained.

Plans for sewerage construction shall meet all design requirements of the local sewering agency and shall also meet all design requirements as established from time to time by the Chief Engineer. Inspection of all sewerage construction under this Section shall be made by personnel of the Districts in the manner described in Section 303. An approval of plans for sewerage construction shall expire one (1) year after date of approval unless construction has been initiated by that time.

SECTION 302 - PERMIT FOR SEWER SIX INCHES OR SMALLER IN DIAMETER CONNECTING DIRECTLY TO A TRUNK SEWER OF THE DISTRICTS

Any person desiring to connect a sewer six (6) inches or smaller in diameter directly to a trunk sewer of the Districts shall make written application to the Chief Engineer on a Districts' Trunk Sewer Connection Permit application form. The applicant shall complete the form and furnish such additional information as required by the Chief Engineer to substantiate that the proposed work or use will comply with the provisions of this Ordinance.

A Trunk Sewer Connection Permit will not be issued unless the applicant has first obtained approval from the local sewering agency in the area in which the property is located. A Trunk Sewer Connection Permit will not be issued for any sewer which will convey industrial wastewater unless the discharger has first obtained a Districts' Permit for Industrial Wastewater Discharge.

Direct connection of a sewer six (6) inches or smaller in diameter to a Districts' trunk sewer will be permitted only if the Chief Engineer determines that a suitable local sewer is not available, that adequate trunk sewer capacity exists, that the connection will function properly and that the connection will not adversely affect existing or anticipated facilities or operations of the Districts.

Sewers six (6) inches or smaller in diameter to be connected directly to a Districts' trunk sewer shall be constructed in a manner and at a location specified by the Districts. Inspection of the connections to a trunk sewer shall be made by personnel of the Districts in the manner described in Section 303.

No sewer exceeding six (6) inches in diameter shall be connected directly to a Districts' trunk sewer without the prior approval of plans for sewerage construction, in accordance with Section 301 of this Ordinance.

A Districts' Trunk Sewer Connection Permit shall expire 120 days after issuance unless construction of the connection has been initiated by that time. A permit will not be required from the Districts for connection of a sewer six (6) inches or smaller in diameter which does not connect directly to a trunk sewer, providing the sewer will not carry industrial wastewaters.

SECTION 303 - INSPECTION OF CONSTRUCTION

All sewers to be connected directly to a Districts' trunk sewer will be inspected by personnel of the Districts during construction. The Districts shall be notified at least 48 hours prior to excavating to expose a Districts' sewer or commencing construction of a manhole on a Districts' sewer. In making a connection to a Districts' trunk sewer, no physical alteration of the Districts' facilities shall commence until a Districts' inspector is present.

Sewerage facilities which will not be directly connected to a Districts' sewer will not be inspected routinely by the Districts during construction. Upon completion of construction and prior to removal of the downstream bulkhead and upon receiving 48 hours notice, the Districts will inspect the work to determine if it has been constructed in a satisfactory manner and to determine if all facilities are cleaned of construction debris that could be flushed into the Districts' sewers.

No wastewater shall be discharged into any sewerage facility tributary to a Districts' facility prior to obtaining inspection and approval of sewerage construction by the Districts.

Following satisfactory completion of construction, the Districts will, if requested, issue a construction inspection completion statement.

SECTION 304 - PLAN APPROVALS AND PERMITS NOT TRANSFERABLE

Approval of plans for sewerage construction and Trunk Sewer Connection Permits are not transferable from one person to another person or from one location to another location.

SECTION 305 - PROHIBITED RAINWATER, GROUNDWATER AND OTHER WATER DISCHARGES

No person shall discharge or cause to be discharged any contaminated or uncontaminated rainwater, water used in fighting fires, stormwater, groundwater, artesian well water, street drainage, yard drainage, water from yard fountains, ponds or lawn sprays into any sewerage facility which directly or indirectly discharges to facilities owned by the Districts, except where prior approval for such discharge of water is given by the Chief Engineer. Approved discharges shall be considered industrial wastewater discharges under this Ordinance. Any such approval may be revoked at any time by the Chief Engineer.

SECTION 306 - PROHIBITED INDUSTRIAL WASTEWATER DISCHARGE

No industrial wastewaters shall be discharged to a Districts' trunk sewer or to a sewer discharging directly or indirectly to a Districts' trunk sewer until a Permit for Industrial Wastewater Discharge has been approved by the Districts.

SECTION 307 - MANHOLE RECONSTRUCTION NOTIFICATION

The work of adjusting manholes on Districts' sewers to new elevations will be performed by personnel of the Districts in cooperation with the paving contractor and in accordance with established procedures of the Districts. The person proposing or performing work necessitating the adjustment of manholes on Districts' sewers to a new elevation shall be responsible for notifying the Districts at least 48 hours in advance of the work.

SECTION 308 - IMPROPER USE OF CONNECTED SEWERS

The Districts may inspect any lateral or collecting sewers that discharge wastewater directly or indirectly to the Districts' trunk sewers. If the Chief Engineer determines that the improper use, maintenance, or construction of a lateral or collecting sewer causes or contributes to the discharge of septic wastewater, excessive groundwater, debris or any other objectionable substance to the Districts' sewers, the Chief Engineer may give notice of the unsatisfactory condition to any discharger contributing to such condition and to the local sewering agency responsible for the maintenance of such sewer, and shall direct that condition be corrected. In the event of a failure to comply with the Chief Engineer's directive, the Districts may disconnect such lateral or collecting sewer from the Districts' sewerage system.

SECTION 309 - CHARGE FOR EXCESSIVE SEWER MAINTENANCE

No person shall discharge or cause to be discharged to a Districts' trunk sewer, either directly or indirectly, any waste that obstructs, interferes with, or otherwise requires excessive maintenance of any Districts' sewer or sewerage facility; including any waste that creates a stoppage or breakage; any toxic, hazardous or odorous condition; or any damage or deterioration of any Districts' sewer or sewerage facility. Any excessive sewer or sewerage maintenance expenses or reconstruction costs including administrative costs attributable thereto shall be charged to the discharger causing or contributing to such conditions. Any refusal to pay such charges shall constitute a violation of this Ordinance.


PART IV - INDUSTRIAL WASTEWATERS

SECTION 401 - PERMIT FOR INDUSTRIAL WASTEWATER DISCHARGE

Except as hereafter provided, no person shall discharge or cause to be discharged any industrial wastewaters directly or indirectly to the sewerage facilities owned by the Districts without first obtaining a Districts' Permit for Industrial Wastewater Discharge (Permit). A Districts' Permit shall be obtained prior to commencement of any construction of new or modified facilities which will discharge industrial wastewater to the sewer. A separate Permit shall be required for each industrial wastewater connection to a public sewer discharging directly or indirectly to the Districts' sewerage system. The use of a sewer connection which is the subject of a Districts' Permit by anyone other than the person named in the Permit is prohibited. A Permit or Permit revision shall also be obtained by dischargers who use transportable treatment systems for pretreatment of industrial wastewater. Any person who operates a transportable treatment system must receive written authorization from the Chief Engineer prior to commencement of operations at any industrial facility. Any person operating a transportable treatment system shall comply with all requirements established by the Chief Engineer for such systems. A Permit shall also be obtained by all persons generating industrial wastewater, other than hauled domestic wastewater, which enters the Districts' sewerage system by means of liquid waste haulers.

The Chief Engineer may exempt certain classes of dischargers of industrial wastewaters from the requirement to obtain a Permit if the quantity and quality of the wastewater is determined to be unlikely to create significant effects on the Districts' sewerage system or produce violations of state law or federal regulations.

The Permit may require pretreatment of industrial wastewaters before discharge, restriction of peak flow discharges, discharge of certain wastewaters only to specified sewers of the Districts, relocation of point of discharge, consolidation of wastewater discharge connections, prohibition of discharge of certain wastewater components or characteristics, batch treatment and discharge, restriction of discharge to certain hours of the day, and such other conditions as may be required to effectuate the purposes of this Ordinance. The Permit may also require payment of additional charges to defray increased costs of the Districts created by the wastewater discharge and payment of equivalent connection fees, equivalent annexation fees or other equivalent charges for dischargers not located within the Districts (or who, historically, have not been subject to the Districts' normal revenue charges).

Permits for facilities that receive for treatment, recycling or reclamation one or more wastes generated off-site, may additionally require monitoring of influent wastestreams and may restrict the types and quantities of wastes accepted.

The Districts' Permit is not transferable to a new business location or to a new business. Each discharger shall immediately notify the Districts in writing of any change in the name or legal capacity of the discharger. The Permit shall be voidable by the Chief Engineer upon non-use, cessation of operations, transfer of business ownership, or the issuance of a new Permit for the same sewer connection.

No person shall discharge industrial wastewaters in excess of the quantity or quality limits stated in the Permit. The violation of any Permit condition or requirement shall constitute a violation of this Ordinance and shall be punishable as provided by law. Any person who, as defined by the Chief Engineer, significantly increases or decreases the flow rate or significantly alters the quality of wastewater discharge shall immediately apply for and obtain a Permit revision. Any discharger who modifies an industrial plant, operating mode, process, or wastewater treatment facility in a manner which, as defined by the Chief Engineer, would significantly increase or decrease the flow rate or significantly alter the quality of the wastewater discharge described in a Permit or Wastewater Treatment Surcharge Statement shall first apply for and obtain a Permit revision. This Permit revision shall be obtained prior to the commencement of any construction of new plant facilities or operation of modified facilities by the wastewater discharger.

As a condition of the Districts' issuance of a Permit, each discharger shall agree that upon receipt of a Notice of Suspension under Section 404 of this Ordinance or upon receipt of a Notice of Revocation under Section 405 of this Ordinance, such discharger shall immediately cease and desist the direct or indirect discharge of all industrial wastewater to the Districts' sewerage system. As a further condition of the issuance of a Permit, it shall be agreed that, upon application by District No. 2, any court of competent jurisdiction may enter a temporary restraining order and preliminary and permanent injunction restraining any discharges in violation of this Ordinance.

SECTION 402 - PROCEDURE FOR OBTAINING A DISTRICTS' PERMIT FOR INDUSTRIAL WASTEWATER DISCHARGE

Applicants for a Permit for Industrial Wastewater Discharge shall complete a Districts' application form available at the Districts' offices or at the office of the local sewering agency having jurisdiction in the area in which the discharge is to be made. Following approval, the local sewering agency shall forward the application form and appurtenant plans and data to the Districts for review and approval. The Districts may require additional information from the discharger beyond that required on the application form. Detailed instructions for obtaining a Permit are contained in the Districts' booklet, "Information and Instructions for Obtaining an Industrial Wastewater Discharge Permit" which can be obtained at the Districts' offices or at the office of the local sewering agency. Applicants for permits shall comply with all such instructions.

Upon receipt of all required information, the Districts will determine whether the discharger is obligated to pay a connection fee. This fee shall be paid to the Districts before the Permit is issued. Dischargers shall be assigned a single surcharge account and a single sewer capacity baseline for all contiguous property even though individual permits may be issued for separate connections from such property. After all information and fees are received, the application shall be processed and, upon approval, be signed by representatives of both the local sewering agency and the Districts, and one copy returned to the applicant. When properly signed, the application form together with any documents attached thereto shall constitute a valid Permit.

The application shall be approved if the applicant has complied with all applicable requirements of this Ordinance and furnished to the Districts all requested information and if the Chief Engineer determines that there is adequate capacity in the Districts' facilities to convey, treat, and dispose of the wastewaters. Dischargers shall comply with all terms, conditions, limitations, requirements, and instructions contained in their Permit. Violations of Permit terms, conditions, limitations, requirements, and instructions including any federal pretreatment standards or any effluent limits adopted by the Districts or required by state law, shall be enforceable as violations of this Ordinance, and shall be punishable as provided by law.

In the event that the Chief Engineer determines that any person is discharging industrial wastewater directly or indirectly to the Districts' sewerage system without a valid Permit, the Chief Engineer may issue to such person a Temporary Permit for Industrial Wastewater Discharge (Temporary Permit) containing such conditions, limitations, restrictions, and other provisions or requirements which the Chief Engineer determines are necessary or advisable to protect the Districts' system and to assure compliance with all federal, state and Districts' discharge requirements. This Temporary Permit shall be enforceable until such time as a Permit is issued. The discharger shall immediately comply with all of the provisions and requirements of such Temporary Permit, and shall apply for a Permit within thirty (30) days from the issuance of the Temporary Permit. A Temporary Permit is revocable by the Chief Engineer at any time. Any person whose Temporary Permit is revoked shall immediately cease and desist all discharge of any industrial wastewaters.

SECTION 403 - CHANGE OF RESTRICTIONS IN PERMIT FOR INDUSTRIAL WASTEWATER DISCHARGE

The Chief Engineer may upon reasonable notice to the discharger change or modify the restrictions or conditions of a Permit from time to time to effectuate the purposes of this Ordinance. Alternatively, the Chief Engineer may require the discharger to apply for a new or revised Permit. The Chief Engineer shall allow an industrial wastewater discharger a reasonable period of time to comply with any changes required in the Permit.

SECTION 404 - SUSPENSION OF PERMITS ISSUED UNDER THIS ORDINANCE

The Chief Engineer may suspend any permit issued under the authority of this Ordinance for a period not to exceed forty-five (45) days when such suspension is necessary in order to stop a discharge which presents an imminent hazard to the public health, safety or welfare, to the environment, to the local sewering agency's system, or to the Districts' sewerage system.

Any discharger notified of a permit suspension shall immediately cease and desist the discharge of all industrial wastewater to the sewerage system. In the event of a failure of the discharger to comply voluntarily with the suspension order, the Chief Engineer shall take such steps as are reasonably necessary to insure compliance which may include blocking or severing the discharger's connection to the Districts' system.

Any discharger whose permit is suspended may file with the Chief Engineer a request for a suspension hearing. Such a request shall not stay the suspension. In the event of such request, the Chief Engineer shall, within fourteen (14) days of the receipt of such request, hold a hearing on the suspension and shall either confirm or terminate the suspension.

Reasonable notice of the suspension hearing shall be given to the discharger in the manner provided for in Section 204. At this hearing the discharger whose permit is suspended may appear personally or through counsel, cross-examine witnesses and present evidence. A decision on the suspension shall be made by the Chief Engineer within seventy-two (72) hours after the close of the hearing or the order of suspension shall be stayed until a decision is made either approving or terminating the suspension action. The decision of the Chief Engineer shall be made in writing and shall contain a brief summary of the evidence considered together with a written statement of findings of fact and conclusions of law.

The Chief Engineer shall reinstate the suspended permit upon proof of satisfactory compliance with all discharge requirements of the Districts including all additional permit requirements deemed necessary by the Chief Engineer.

The Districts' legal counsel may, upon recommendation of the Chief Engineer, commence and prosecute such legal action as may be appropriate to enforce the provisions of this Section.

SECTION 405 - REVOCATION OF PERMITS ISSUED UNDER THIS ORDINANCE

The Board of Directors of District No. 2 may revoke any permit issued under the authority of the Ordinance upon a finding that the discharger has violated any provision of this Ordinance, or any other ordinance adapted by the Districts. No Revocation of a Permit, other than a Temporary Permit, shall be ordered until a revocation hearing on the question has been held by the Chief Engineer. At this revocation hearing, the discharger may appear personally or through counsel, cross-examine witnesses, and present evidence. Notice of the revocation hearing shall be given to the discharger in accordance with Section 204 at least fifteen (15) days prior to the date of the hearing. The Chief Engineer may, without prior Board authorization, initiate a permit revocation hearing and action.

If at the conclusion of the revocation hearing the Chief Engineer recommends revocation of the permit, he shall submit a written report with his recommendation to the Board of Directors of District No. 2 together with a brief summary of the information considered and the conclusions reached. The Board, after considering the information presented at the revocation hearing and the Chief Engineer's report, and any report submitted by the discharger, shall adopt findings supported by the information and may adopt, reject or modify the report in whole or in part and shall make its decision and issue its order.

The decision of the Board of Directors of District No. 2 on whether or not to revoke a permit shall be made in writing and served promptly upon the discharger in the manner provided in Section 204. The order of the Board may be effective immediately or at a later date as may be specified in such order.

Any discharger whose permit has been revoked shall immediately comply with any order of revocation issued by the Board of Directors of District No. 2 and shall cease and desist all discharges. The Chief Engineer may permanently block or sever any connection to the Districts' sewerage system of any discharger whose permit has been revoked, if such action is necessary to insure compliance with the order of revocation.

Before any further discharge of wastewater may be made by the discharger whose permit has been revoked, the discharger must apply for a new Districts' permit, pay all charges that would be required upon initial application together with all delinquent fees, charges and penalties and such other sums as the discharger may owe to the Districts, excluding any connection fees previously paid. Costs incurred by the Districts, including administrative costs, in revoking the permit and disconnecting the discharger from the Districts' sewerage system shall be paid by the discharger before issuance of a new permit.

SECTION 406 - PROHIBITED AND RESTRICTED WASTE DISCHARGES

No person shall discharge or cause to be discharged to the Districts' sewerage systems, or to any public sewer that directly or indirectly connects to the Districts' sewerage systems, any wastes which may have an adverse or harmful effect on sewers, maintenance personnel, wastewater treatment plant personnel or equipment, treatment plant processes or the quality of treatment plant effluent or residue, public or private property, or wastes which may otherwise endanger the public, the environment, or create a public nuisance. No person shall discharge or cause to be discharged to the Districts' sewerage systems, or to any public sewer that directly or indirectly connects to the Districts' sewerage systems, any wastes which adversely affect air quality, adversely affect water reclamation processes or the quality of reclaimed water, cause or contribute to a violation of any requirement of any Districts' facilities permit, any National Pollutant Discharge Elimination System Permit or waste discharge requirements, or place the Districts in noncompliance with any of the statutory authorities listed in Title 40, Code of Federal Regulations, Part 403.3(i), or place the Districts in noncompliance with any local, state or federal law including any air quality standard or regulation such as the New Source Performance Standards (set forth in Part 60, Chapter I, Title 40, Code of Federal Regulations), the National Emissions Standards for Hazardous Air Pollutants (set forth in Part 61, Chapter I, Title 40, Code of Federal Regulations), or any standard or regulation promulgated by the California Air Resources Board or the South Coast Air Quality Management District.  Prohibited or restricted wastes described in this section shall not be discharged, processed or stored in such a manner that such wastes could have access to the public sewer. Any prohibited or restricted wastes found in any approved monitoring facility as referred to in Section 414 shall be conclusively presumed to have been discharged to the public sewer and the discharger shall be subject to the enforcement provisions of this Ordinance.

Dischargers shall immediately notify the Districts of the discharge of any prohibited waste, or of the discharge of excessive quantities or concentrations, as defined by the Chief Engineer, of any restricted waste. Dischargers shall also notify the Districts of any circumstances affecting their plant processes or facilities which may potentially result in the discharge of a prohibited waste or of excessive quantities of concentrations, as defined by the Chief Engineer, of any restricted waste, including but not limited to any malfunction, upset or improper operation of the discharger's plant processes, pretreatment systems, or spill containment facilities, or any diversion or bypass of wastewater. Failure to immediately notify the Districts of any such condition shall be a separate violation of this Ordinance.

(EE) Any waste containing excessive quantities or concentrations, as defined by the Chief Engineer, of ammonia.

(FF) Any waste containing excessive quantities or concentrations, as defined by the Chief Engineer, of benzene or other volatile organic compounds or any other waste constituent that alone or in combination with other materials adversely affects air quality.

The Chief Engineer shall, from time to time, establish quantitative or other limitations applicable to industrial wastewater discharges when in his judgment it is necessary to protect the Districts' sewerage system or to be in compliance with state or local law or federal regulations. Such limitations shall apply at the industrial wastewater monitoring facility or station prior to mixing with domestic wastewaters. Wastewater discharges in excess of the limits established by the Chief Engineer or any state law or applicable federal pretreatment standard shall constitute excessive concentrations or quantities prohibited by this Section 406. The Chief Engineer shall promulgate and maintain a list of limitations established for restricted wastes which are generally applicable to all dischargers and shall make such list available upon request.

The Chief Engineer shall establish quantitative limitations for dischargers which, because of their location, quantity or quality of discharge, can degrade the quality of wastewater treatment plant effluent or residue or air quality to a level that prevents or inhibits Districts' efforts to reuse or dispose of the water or residue or causes any unusual operation or maintenance problems in the sewerage system. The Chief Engineer, in determining the unacceptability of specific wastes, shall consider the nature of the waste and the adequacy and nature of the collection, treatment and disposal system available to accept the waste.

SECTION 407 - MEDICAL AND INFECTIOUS WASTES

The Chief Engineer may prohibit the discharge of infectious wastes and may require that any such wastes be rendered noninfectious prior to discharge if deemed to pose a threat to public health and safety. No person shall discharge solid wastes from hospitals, clinics, offices of medical doctors, convalescent homes, medical laboratories or other medical facilities to the Districts' sewerage system including, but not limited to, hypodermic needles, syringes, instruments, utensils or other paper and plastic items of a disposable nature, or recognizable portions of the human anatomy or laboratory animals, except where prior written approval for such discharges is given by the Chief Engineer. Approved discharges shall be considered industrial wastewater discharges under this Ordinance. Any such approval may be revoked at any time by the Chief Engineer.

SECTION 408 - AVAILABILITY OF DISTRICTS' FACILITIES

If sewerage capacity is not available, the Districts may require any industrial wastewater discharger to restrict a discharge until sufficient capacity can be made available. When requested, the Districts will advise persons desiring to locate new facilities of those areas where industrial wastewater of their proposed quantity and quality can be accommodated by available sewerage facilities. The Districts may refuse service to persons locating facilities in areas where their proposed quantity or quality of industrial wastewater would adversely affect the available sewerage facility.

SECTION 409 - WASTEWATER TREATMENT SURCHARGE FOR INDUSTRIAL DISCHARGERS

Each industrial discharger not exempted under Section 411 shall pay to the Districts an annual wastewater treatment surcharge in accordance with Section 214. The wastewater treatment surcharge shall be determined in accordance with each such discharger's contribution of flow, chemical oxygen demand, suspended solids, and peak flow. The wastewater treatment surcharge shall be based on the appropriate Districts' sewerage system's maintenance, operation and capital expenditures for providing wastewater collection, treatment and disposal services as described in Section 410.

The annual wastewater treatment surcharge shall be computed by the following formula:

Surcharge = a(V) + b(COD) + c(SS) + d(M)(P) Where:

Surcharge = Net annual wastewater treatment surcharge in dollars.

V = Total annual volume of wastewater flow, in millions of gallons. COD = Total annual wastewater discharge of chemical oxygen demand, in thousands of pounds.

SS = Total annual wastewater discharge of suspended solids, in thousands of pounds.

P = Peak wastewater discharge rate over a thirty (30) minute period occurring between the hours of 8:00 a.m. and 10:00 p.m. in gallons per minute. Values of "P" which are equal to or less than ten (10) gallons per minute shall be considered equal to zero.

a,b,c,d = Unit charge rates adopted by each individual District based upon the projected annual costs for wastewater collection, treatment and disposal, in dollars per unit, as described in Section 410.

M = Multiplying factor accounting for increased Districts' costs due to high ratios of industrial discharge peak-to-average flow rates (P/A), where "P" is defined above, and "A" is the average wastewater discharge rate, determined by dividing "V" by the total annual hours of significant wastewater discharge for the industrial discharger, converted to gallons per minute. Factor M is obtained from Figure 1.

The quantities for yearly total flows, COD, suspended solids, and peak flow rates used in the above formula are to be determined by wastewater flow measurements and periodic sampling and analysis of the wastewater in accordance with such procedures as may be specified by the Chief Engineer. Extensive wastewater sampling, analysis, and flow measurement may be required by the Chief Engineer for larger wastewater dischargers or for those who discharge pollutants in significantly large or unusual amounts.

The Chief Engineer shall set the minimum requirements for sampling, analysis, and flow measurement by the discharger necessary to establish quantities to be used in the above formula.

The Chief Engineer shall establish a wastewater treatment charge per million gallons applicable to industrial dischargers whose yearly flow does not exceed six (6) million gallons. This charge shall be based upon average costs of providing wastewater services to industrial dischargers falling within this classification and may be used upon approval of the Chief Engineer in lieu of the preceding formula. Approval of the Chief Engineer shall be withheld only with respect to discharges of unusually high strength wastes in terms of COD and suspended solids. Wastewater treatment surcharges for such dischargers shall be due and payable on the dates set forth in Section 214 or less frequently upon the determination of the Chief Engineer. The Chief Engineer may from time to time establish a different quantitative limitation than that set forth above so long as the same does not exceed a yearly flow of twelve and one-half million gallons. The charge described in this paragraph shall not apply to industrial dischargers subject to user charges established under Section 422.

The Chief Engineer shall establish a charge per employee for domestic wastewater discharges which shall be paid by all industrial dischargers whose domestic wastewater is not included in the general wastewater treatment surcharge payment. Such charge shall be based upon the average quantity and quality of domestic wastewater per employee and the charge rates established for the wastewater treatment surcharge formula.

If the industrial discharger elects or is required by the Districts to discharge the peak rates of industrial wastewater flow during the nighttime hours between 10:00 p.m. and 8:00 a.m., the flow discharge shall be made approximately uniform during these hours. Certain industrial dischargers may be prohibited from discharging peak flow during the nighttime hours if these flows would adversely affect Districts' operations.

SECTION 410 - ESTABLISHMENT OF UNIT CHARGE RATES FOR WASTEWATER TREATMENT SURCHARGE

Unit charge rates a, b, c, and d in the wastewater treatment surcharge formula, as described in Section 409, shall be established for each sewerage system by the procedure described herein and shall be adopted by the individual Districts which utilize each system.

For each sewerage system, appropriate unit charge rate parameters for flow, chemical oxygen demand, and suspended solids--respectively designated a (in dollars per million gallons), b (in dollars per 1000 pounds of COD) and c (in dollars per 1000 pounds of suspended solids)--shall be determined by the following method:

 (A) The total annual operation and maintenance costs for each sewerage system, excluding the annual costs for the administration and operation of the industrial waste program, shall be estimated for the accrual year or accrual years in the event of a multiple year rate adoption and distributed among the three wastewater charge parameters of flow, chemical oxygen demand, and suspended solids. This distribution shall be in accordance with the Chief Engineer's determination of the average distribution of such sewerage system's costs predominantly related to each parameter for the most recent year for which complete data are available.

(B) The total annual net capital costs for each sewerage system shall be estimated for the accrual year or accrual years in the event of a multiple year rate adoption and distributed among the three wastewater charge parameters of flow, chemical oxygen demand, and suspended solids in accordance with the Chief Engineer's determination of the portion of the sewerage system's net capital costs predominantly related to each parameter in the relevant year.

(C) The sum of the total annual accrual year operation and maintenance costs in (A) above and the total annual net capital costs in (B) above shall be used to determine the weighted distribution for wastewater charge parameters of flow, chemical oxygen demand, and suspended solids for each sewerage system for the relevant year.

(D) The sum of the total annual operation and maintenance costs and the total annual net capital costs and necessary reserves for each sewerage system as determined by the Chief Engineer shall be offset by appropriate revenue sources to determine the remaining revenue required to operate each sewerage system in an accrual year. The remaining revenue required shall be distributed to the three wastewater charge parameters of flow, chemical oxygen demand, and suspended solids as determined in (C) above. The costs attributed to each parameter shall be divided by the projected annual total flow volume and total masses of chemical oxygen demand, and suspended solids, respectively, to be treated by the sewerage system in an accrual year. The projected annual total flow volume and total masses of chemical oxygen demand, and suspended solids shall be based on an estimated mass balance of all wastewater discharges to the sewerage system as determined by the Chief Engineer. The unit wastewater charge rates so determined will be expressed in dollars per million gallons for a1 and in dollars per thousands pounds for b1 and c1.

(E) To account for the costs of monitoring, inspection, permitting, enforcement, laboratory services and other associated administrative services, the respective rates for a1, b1, and c1 calculated in (D) above shall be multiplied by the respective unit rates for a, b, and c as established for the 1997-98 fiscal year and divided by the respective unit rates for a1, b1, and c1 established for the 1997-98 fiscal year. The resulting values, expressed in dollars per million gallons for flow, and in dollars per thousand pounds for COD and suspended solids, shall be the unit wastewater surcharge rates.

For each sewerage system in the Districts, the unit charge rate related to peak flow and designated d (in dollars per gallon per minute of peak flow) shall be equal to the unit charge rate for peak flow adopted for the 1997-98 fiscal year multiplied by the total charge for the relevant year that would be due using the unit rates established in (E) above and the loadings for a sewage unit (260 gallons per day, 1.22 lbs. per day COD, and 0.59 lbs. per day suspended solids) and divided by the total charge that would have been due using the unit rates for the 1997-98 fiscal year and the loadings for a sewage unit.

SECTION 411 - WASTEWATER TREATMENT SURCHARGE STATEMENT

Each industrial discharger, except for those dischargers that fall within a flow classification exempted by the Chief Engineer, shall file annually with the Districts a wastewater treatment surcharge statement. All surcharge statements and any required payments shall be filed on or before August 15 following the end of the fiscal year. Each industrial discharger shall report on such statement the total annual surcharge due to the Districts and the wastewater discharge data used in making such calculations. Such information shall be provided on a form prepared by the Chief Engineer and shall be signed by the discharger under penalty of perjury. Dischargers shall comply with all instructions which accompany the Districts' forms. The discharger shall submit such additional data as the Chief Engineer may from time to time require in implementing the wastewater treatment surcharge program.

SECTION 412 - PRETREATMENT OF INDUSTRIAL WASTEWATERS

The Chief Engineer may require an industrial discharger to provide wastewater pretreatment systems or facilities whenever the Chief Engineer determines that it is necessary or advisable to treat industrial flows prior to discharge to the sewer, to restrict or prevent the discharge to the sewer of certain waste constituents, to distribute any peak discharges of industrial wastewaters more equally over a long time period, to comply with any state discharge or pretreatment requirements, to comply with federal pretreatment standards, or to accomplish any pretreatment result required by the Chief Engineer in order to effectuate the purposes of this Ordinance. Any pretreatment facilities required by the Chief Engineer shall be provided and maintained at the expense of the industrial wastewater discharger. Pretreatment systems or facilities shall not be installed or operated without the prior written approval of the Chief Engineer. The requirement for such approval, however, shall not absolve the industrial discharger of the responsibility for meeting any industrial wastewater discharge limitation imposed by the Districts or by the state or federal government. If inspections or other information reveal that pretreatment systems and facilities are not installed or operated in conformance with the plans and procedures submitted to and approved by the Districts, or are not operated in compliance with the discharge requirements and limitations imposed by the Districts, the industrial discharger shall make such modifications as are necessary to meet such requirements. In special cases, the Chief Engineer may require construction of sewer lines by the discharger to convey certain industrial wastes to specific trunk sewers in addition to or in lieu of the installation of a pretreatment system. Users who have the potential to discharge significant levels of flammable substances, as defined by the Chief Engineer, shall install and maintain approved combustible gas detection meter systems. All pretreatment systems determined by the Chief Engineer to require engineering design shall have plans prepared and signed by a civil, chemical, or mechanical engineer registered in the State of California or a registered engineer of other suitable discipline as determined by the Chief Engineer.

Gravity separation interceptors, equalization tanks, neutralization chambers, control manholes or other monitoring facilities, and spill containment systems, may be required by the Chief Engineer as he deems necessary to remove prohibited settleable and floatable solids, to equalize wastewater streams varying greatly in quantity and/or quality, to neutralize low or high pH wastewater, to facilitate inspection, flow measurement and sampling, and to prevent discharge to the sewer of quantities of prohibited or restricted materials resulting from a rupture of a tank or pipeline or other such accidental occurrences. Spill containment systems shall conform to guidelines established by the Chief Engineer. Floor drains from commercial or manufacturing buildings, warehouses or multi-use structures shall first discharge to a gravity separation interceptor before entry into the sewer system.

Any discharger which has a pumping plant or long private sewer leading from the industrial wastewater pretreatment system to the nearest public sewer may be required to install a monitoring facility or other equipment on the private sewer immediately before the junction with the public sewer. Such facility shall be required by the Chief Engineer to be designed and constructed so as to enable Districts' personnel to verify the quantity and quality of wastewater actually discharged into the public sewer.

The Chief Engineer may from time to time adopt specific requirements for pretreatment systems and facilities. Such requirements shall be set forth in the Districts' waste discharge guidelines and shall be summarized in the most recent edition of the Districts' booklet entitled "Information and Instructions for Obtaining an Industrial Wastewater Discharge Permit." This Permit booklet shall be made available at the Districts' offices and at the office of the local sewering agency having jurisdiction over the local sewers tributary to the Districts' sewerage system. Dischargers shall comply with all pretreatment requirements, requirements for construction of facilities, requirement for wastewater sampling and analysis, and requirements for submittal of permits specified in the waste discharge guidelines and the Permit booklet.

SECTION 413 - SEPARATION OF DOMESTIC AND INDUSTRIAL WASTEWATERS

All domestic wastewaters from rest rooms, showers, drinking fountains, etc., shall be kept separate from all industrial wastewaters until the industrial wastewaters have passed through any required pretreatment system or device and the discharger's monitoring facility or station.

SECTION 414 - WASTEWATER MONITORING AND REPORTING

(A) SURCHARGE REPORTING

    Each industrial wastewater discharger shall make such measurements of wastewater flow volumes, flow rates, chemical oxygen demand (COD) and suspended solids (SS) as are necessary to accurately determine its annual wastewater treatment surcharge unless specifically relieved of such obligation by the Chief Engineer as provided under Section 409 of this Ordinance. Each discharger shall take at least the minimum number of flow measurements and wastewater samples for COD and SS analyses as required by the Chief Engineer. Dischargers who fail to perform required monitoring, fail to accurately perform such monitoring, or fail to properly report the results of such monitoring to the Districts shall pay the costs of any Districts' monitoring needed to satisfy applicable monitoring requirements. Dischargers with more than one identifiable waste stream or with large variations or fluctuations in wastewater quantity or quality must take a sufficient number of flow measurements and samples to accurately represent the total wastewater flow from the discharger's facility including each identifiable waste stream, variation or fluctuation. The Chief Engineer may require industrial wastewater dischargers to provide additional or continuous wastewater flow measurement and sampling. If a discharger fails to take the minimum number of wastewater samples or flow measurements, fails to accurately take such samples or measurements, or fails to properly report the results of such monitoring to the Districts, then the Chief Engineer may determine that the discharger's wastewater monitoring, including sampling, analysis, flow measurements or other engineering investigations, shall be undertaken by the Districts with all associated costs of such monitoring to be paid by the discharger.

    Wastewater samples and flow measurements reported to the Districts shall be taken from monitoring facilities of a design and configuration approved by the Chief Engineer. Samples shall be composites taken at least once per hour over a 24-hour period, properly refrigerated, and where appropriate, composited according to wastewater flow rates during the 24 hours. Dischargers required to have wastewater flow monitoring systems shall use such systems to obtain accurate flow-proportioned composite samples, and shall report the flow volumes and flow rates recorded by such systems on their annual surcharge statements. Dischargers shall monitor wastewater discharges which are representative of the entire range of plant operations.

    Dischargers shall report to the Districts the analytical results for COD and SS for each wastewater sample taken and analyzed during the fiscal year. Copies of all laboratory results of such analyses shall be submitted with the discharger's annual wastewater treatment surcharge statement. If a discharger believes that an analysis is in error or not truly representative of its wastewater, the discharger shall so state, submit the analysis, and furnish all reasons why the analysis is believed to be erroneous or unrepresentative.

    The Districts will take measurements and samples from time to time to verify the wastewater characteristics reported to the Districts. Dischargers shall assist the Districts where necessary to obtain correct and accurate measurements, and shall not interfere with the operations of the Districts' personnel or equipment. Upon audit of a discharger's surcharge statement, the Chief Engineer may include the results of any Districts' monitoring of the discharger's wastewater or substitute Districts' monitoring results for monitoring by the discharger deemed faulty by the Chief Engineer.

    Wastewater samples shall be analyzed by a state certified laboratory or laboratory approved by the Chief Engineer. All analyses shall be performed in accordance with the procedures specified by the U.S. Environmental Protection Agency (EPA) in the most current "Guidelines Establishing Test Procedures for the Analysis of Pollutants" (40 Code of Federal Regulations, Part 136) (Guidelines). For those industrial wastewaters which contain unusual quantities or types of wastes, the Chief Engineer may require (1) use of alternate methods or procedures specified in the Guidelines or the most current of Standard Methods for the Examination of Water and Wastewater (Standard Methods), (2) use of modifications to the methods or procedures specified in the Guidelines or Standard Methods, or (3) use of any other test method or procedure that gives a reasonable value of the pollutant. If no appropriate procedure is provided in the above references, the Chief Engineer may approve the standard procedure of the industry or other procedure to measure wastewater constituents. For wastewater analyses that would be significantly affected by conditions of the wastewater sample which are different from normal conditions prevailing in the sewerage system (e.g., pH), the Districts may require that the sample be adjusted to normal sewerage system conditions before analysis. Any independent laboratory or discharger performing wastewater analyses shall furnish any required analytical data or information on the procedures or equipment used if requested to do so by the Chief Engineer. Dischargers shall clearly identify on their reports to the Districts any analyses which were not performed in accordance with the procedures provided in the above references.

    All sample results, and all other information, submitted to the Districts shall be verified under penalty of perjury by an authorized representative of the discharger who is also either a general partner or proprietor, or, if a corporation, a principal executive officer of at least the level of vice president. An authorized representative of the discharger shall further certify that all sample results submitted to the Districts are properly composited samples of the discharger's wastewater taken from the discharger's approved monitoring facility at the times and locations stated and in full compliance with all Districts' requirements for sample collection. If samples are collected by an outside consultant, the consultant shall also certify that the samples were collected in full compliance with Districts' requirements. All reports of the results of wastewater analysis shall be signed by the person performing the analysis or other authorized representative of the analytical laboratory performing the analysis, and any limiting words on the report notwithstanding, such signature shall constitute a certificate under penalty of perjury by such person that the reported analysis was actually performed on the sample identified in the report, that the analysis was performed in accordance with the procedures specified in this Ordinance, and that the results described in the report are the true results of the analysis performed.

(B) WASTEWATER MONITORING AND REPORTING FOR OTHER PURPOSES

    In addition to the measurements and samples required for surcharge reporting purposes, each industrial wastewater discharger shall make such other measurements of wastewater constituents as may be specified by the Chief Engineer or required under applicable state law, federal pretreatment standards, or federal regulations. Wastewater flow measurements and samples shall be collected and analyzed and the results submitted under penalty of perjury in the same form as provided in this Section 414 (A) for flow measurements and samples required for surcharge reporting purposes, or as otherwise provided by the Chief Engineer, and shall be reported to the Districts at such times as may be specified by the Chief Engineer.

    Dischargers who fail to perform any required monitoring, fail to accurately perform such monitoring, or fail to properly report to the Districts the results of such monitoring, shall pay all costs of any Districts' monitoring needed to satisfy applicable monitoring requirements.

    Dischargers shall develop compliance schedules for installation of technology required to meet applicable federal pretreatment standards, Districts' pretreatment requirements, and any other applicable discharge requirements established by state law or federal regulations. Dischargers subject to such standards and requirements shall submit to the Districts all notices and self-monitoring reports as are necessary to assess and assure compliance with such standards and requirements including, but not limited to, compliance schedules for the installation of required pretreatment equipment or technology, Baseline Monitoring Reports, Compliance Schedule Progress Reports, Final Compliance Reports, and Notices of Slug Loading. All dischargers shall develop, submit and adhere to any self-monitoring reports and compliance schedules required by the Chief Engineer.

(C) WASTEWATER MONITORING FACILITIES

    All industrial wastewater dischargers required to obtain a Permit shall furnish, install and properly maintain a monitoring facility for wastewater sampling. This monitoring facility shall be of a design or configuration approved by the Chief Engineer, which may include wastewater flow measurement equipment, automatic flow-proportional sampling equipment and automatic wastewater analysis and data recording equipment. The wastewater monitoring facility shall be used to evaluate the quantity and quality of industrial wastewater discharge to the public sewer. Each industrial discharger, as a part of its application for obtaining a Permit, shall propose a suitable location and design for the wastewater monitoring facility. Upon approval of the monitoring facility by the Districts, the discharger shall perform wastewater monitoring at this facility and shall agree to allow the use of this facility for industrial wastewater monitoring by the Districts. The monitoring facility shall be located so as to be safe and accessible to Districts' employees, and shall be constructed in accordance with the Districts' requirements, and all applicable local building codes and other local construction requirements. The discharger's proposal for a wastewater monitoring facility shall comply with Districts' design requirements and shall be reviewed and, if found to be suitable, approved by the Chief Engineer. Plans for all wastewater monitoring facilities, including flow measurement and sampling systems, determined by the Chief Engineer to require engineering design, shall be prepared and signed by a civil, chemical or mechanical engineer registered in the State of California or a registered engineer of other suitable discipline as determined by the Chief Engineer.

    The discharger's wastewater sampling analysis and flow measurement procedures, equipment, and results shall be subject to inspection by the Districts at any time. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times by the discharger. The failure of a discharger to keep approved wastewater monitoring facilities clean and in good working order shall not be grounds for the discharger to claim that any sample results are unrepresentative of the discharger's wastewater. Flow measurement systems shall be regularly maintained and calibrated in accordance with guidelines established by the Chief Engineer.

    Industrial wastewater records and documents, including sample analysis reports, waste haulers' reports, flow meter charts, pH meter charts, and other records of monitoring and sampling activities and reports shall be made available for inspection and copying to the Chief Engineer upon request. Copies or facsimiles of these records shall be provided to the Districts at the discharger's expense upon request. The discharger's records must include for all samples:

      • The date, exact location, method and time of sampling and the names of the person or persons taking the samples;
      • The dates analyses were performed;
      • The person performing the analyses;
      • The analytical techniques/methods used; and
      • The results of such analyses.

    Each industrial discharger shall retain for a minimum of four years any and all records of wastewater monitoring and sampling activities and analytical results. This period of retention shall be extended during the course of any unresolved disputes or litigation involving the discharger and the Districts, or when requested by the Chief Engineer.

SECTION 415 - DISCREPANCIES BETWEEN ACTUAL AND REPORTED INDUSTRIAL WASTEWATER DISCHARGE QUANTITIES

Should Districts' measurements or other investigations indicate that an industrial wastewater discharger is discharging a quantity of wastewater, chemical oxygen demand, suspended solids, or other wastewater constituent or at a flow rate significantly in excess of that stated in the Districts' Permit, the discharger shall apply for a revised Permit.

Should measurements or other investigations indicate that an industrial wastewater discharger has discharged industrial wastewater, chemical oxygen demand, suspended solids or other wastewater constituents at rates or in quantities in excess of those stated by the discharger on a wastewater treatment surcharge statement or other report furnished by the discharger to the Districts, the discharger shall furnish all information in its possession relevant to the apparent discrepancy.

If, after making proper allowance for relevant factors, the Chief Engineer is unable to resolve the discrepancy on the basis of the information available, the Chief Engineer may order that additional information be obtained by Districts' employees through engineering investigations, tests, flow measurements and wastewater sampling and analyses. All costs of engineering investigations, flow measurements, wastewater sampling and analyses and other actions performed by the Districts to resolve the discrepancy shall be paid for by the discharger.

The Chief Engineer shall then make a determination of the amount of any wastewater treatment and disposal charges plus charges for costs of obtaining additional information which are due to the Districts, together with any interest and penalty charges due, and shall notify the discharger of the total charges due. The discharger shall pay such amounts within 45 days after service of written notice. For the purpose of establishing the correct wastewater treatment and disposal charges, the data obtained in these samplings, along with any other relevant information obtained by the Districts or presented by the discharger, shall be used by the Chief Engineer. If an evaluation of wastewater monitoring data of the discharger by the Chief Engineer indicates that some or all of the discharger's data are statistically or otherwise unrelated to the data obtained by the Districts and there is no satisfactory explanation for such discrepancy, the Chief Engineer may reject any or all of the data submitted by the discharger. The Chief Engineer may then use all or portions of data obtained by the Districts to determine appropriate wastewater treatment and disposal charges.

The discharger may, within 12 months after payment of a wastewater treatment surcharge, submit a request for a refund together with appropriate supporting data. The Districts will consider this request and if a refund is due it shall be granted.

SECTION 416 - WASTEWATER DISCHARGER CLASSIFICATIONS

The Chief Engineer may classify wastewater dischargers by categories and establish a wastewater treatment surcharge based upon average flow quality and flow quantity for the category. Such classification may be adjusted by some commonly recognized parameter selected by the Chief Engineer that establishes the relative size of the wastewater discharger being charged.

SECTION 417 - DAMAGES CAUSED BY WASTEWATER DISCHARGES

Any person who discharges any waste which causes or contributes to any damage, injury, excessive wear or deterioration of any Districts' facilities, requires the clean up, removal, reconstruction or replacement of such facilities, brings about any detrimental effects on treatment processes, or causes any other damage including the imposition of fines by state, federal, or other regulatory agencies on the Districts shall be liable to the Districts for all costs and expenses occasioned thereby including administrative costs. If more than one discharger contributed to such damages, each contributing discharger shall be jointly and severally liable to the Districts for all such damages. The Chief Engineer may apportion such damages among the contributing dischargers in accordance with his assessment of the relative contribution of each discharger.

SECTION 418 - DISPOSAL OF VEHICLE-TRANSPORTED LIQUID WASTES TO THE SEWERAGE SYSTEM

No person shall discharge or cause to be discharged any wastes from septic tanks, seepage pits, cesspools, chemical toilets or other approved waste-holding devices, any industrial liquid wastes or any other liquid wastes from a vacuum pumping truck or other liquid transport vehicles, directly or indirectly to the Districts' sewerage facilities without first obtaining a Districts' Permit for Wastewater Transport Truck to Discharge to the Sewerage System (Truck Permit). A separate Truck Permit shall be required for each wastewater transport truck that discharges to the Districts' sewerage system. No person shall discharge any hazardous wastes, as defined by federal or state law, from any vehicle directly or indirectly to the Districts' sewerage system.

A holder of a Truck Permit shall discharge wastewater only at approved locations, and may discharge only domestic wastewater from septic tanks, seepage pits, cesspools, chemical toilets or approved waste-holding devices. Discharge of industrial wastes or any wastes other than specified above is prohibited unless a Districts' Permit for Industrial Wastewater Discharge (Permit) has first been obtained by the generator of such wastes together with the written permission of the Chief Engineer to discharge wastewater at the approved location. Emergency discharge of wastewater not covered under an existing Districts' Permit or Truck Permit may be granted only through written permission of the Chief Engineer, and shall be made only at the locations and times designated by the Chief Engineer.

Applicants for a Truck Permit shall complete a Districts' application form available at the offices of the Districts. Upon receipt of a fully completed application form and all required information, the application shall be processed and reviewed by the Chief Engineer. If approved, one copy of the application form shall be returned to the applicant and, when properly signed by the Chief Engineer, the application form shall constitute a valid Truck Permit. Periodic renewal of the Truck Permit is required.

No person shall discharge any prohibited or restricted wastes as described in Section 406 of this Ordinance at any Districts' approved disposal locations for wastewater transport trucks. The Districts may require proof of the origin of truck-transported wastes, and physical and chemical analysis of any wastes before permission is granted to dispose of such wastes at approved locations. The Districts may reject wastes that the Chief Engineer has reason to believe may be a hazardous waste, an industrial waste that has not been properly permitted, or any other waste with unusual or unknown characteristics which may require further analyses to determine its acceptability for sewer disposal.

Holders of the Truck Permit shall pay all applicable permit fees, permit renewal fees and wastewater disposal fees. The wastewater disposal fee may be paid with Liquid Waste Disposal Fee Coupons available for purchase at Districts' offices or by other methods of payment approved by the Chief Engineer.

The Chief Engineer may revoke or suspend a Truck Permit in accordance with the procedures described in Sections 404 and 405 upon a finding that the permit holder has violated any provision of this Ordinance. Any person whose Truck Permit has been suspended or revoked shall immediately cease and desist all discharge of truck-transported wastes to the Districts' sewerage system. Any person whose Truck Permit has been revoked shall surrender to the Districts any identification decals or devices that have been issued to the person by the Districts.

Any person found to be dumping truck-transported wastes directly or indirectly to the Districts' sewerage system, including sewers owned by the local sewering agency and discharging to the Districts' sewerage system, at any location not specifically authorized by the Districts for such purpose, shall be in violation of this Ordinance. Such person shall at the direction of the Chief Engineer be subject to all enforcement provisions of Section 202 including prohibition by the Districts from any future use of the Districts' sewerage system for disposal of wastes from wastewater transport trucks.

Recreational vehicle sanitary waste disposal stations shall also be subject to regulation by the Chief Engineer. Such regulation may include a permit requirement and the imposition of appropriate fees and charges.

SECTION 419 - TRADE SECRETS

The Districts have determined that the public interest served by not making public any records or other information submitted by dischargers which contain or constitute trade secrets clearly outweighs the public interest served by the disclosure of said records. Accordingly, any trade secrets acquired by the Districts in the course of implementation or enforcement of this Ordinance shall not be made public except to the extent necessary to enforce this Ordinance.

Any claim or trade secret status must be asserted at the time of submission of such information to the Districts by stamping the words "Confidential Business Information" on each page or document containing such information. All information on wastewater effluent quality or quantity furnished by the company or obtained by the Districts shall not be eligible for trade secret status and shall be available as public information.

SECTION 420 - INDUSTRIAL WASTEWATER DISCHARGERS WITHIN A DISTRICT BUT TRIBUTARY TO THE CITY OF LOS ANGELES' TREATMENT FACILITIES

Industrial wastewater discharge permits for dischargers tributary to the treatment facilities of the City of Los Angeles will be issued by the City after approval by the Districts. Inspection of the discharger's plant to determine compliance with industrial wastewater discharge regulations may be made by either City or Districts' personnel under a coordinated plan of inspection developed by the two agencies. Industrial wastewater discharge regulations and effluent limitations of both agencies will apply to the discharger unless one agency specifically waives its requirements.

SECTION 421 - PUBLICATION OF NAMES OF DISCHARGERS IN SIGNIFICANT NONCOMPLIANCE

As required by federal law, the Chief Engineer shall, at least annually, provide public notice in a local newspaper of the identity of those dischargers who are deemed under federal regulations to be significant violators of or in significant noncompliance with the provisions of this Ordinance which implement the federal industrial waste pretreatment program.

SECTION 422 - WASTEWATER TREATMENT USER CHARGE

The Chief Engineer may from time to time establish categories of industrial dischargers having similar wastewater characteristics and with respect to which the Chief Engineer has determined that the burden of complying with Sections 411 and 414 is disproportionate to the anticipated revenue to be derived therefrom. Such industrial dischargers may, at the direction of the Chief Engineer, be required to annually pay a wastewater treatment user charge in lieu of the wastewater treatment surcharge provided for by Section 409. Wastewater treatment user charges shall be due and payable on the dates set forth in Section 214 or less frequently upon the determination of the Chief Engineer. Wastewater dischargers subject to such user charges may be required to periodically submit information necessary for the determination of charge rates or total charges. User charges shall be established by the Chief Engineer to equitably defray costs incurred by the Districts for collection, treatment and disposal of the wastewater from dischargers within these established categories. The Chief Engineer may permit or require an industrial discharger otherwise subject to a wastewater treatment user charge to pay a wastewater treatment surcharge under Section 409 in lieu of the user charge.

SECTION 423 - SPECIAL CHARGES FOR NONCONVENTIONAL INDUSTRIAL WASTEWATER CONSTITUENTS

Special charges for nonconventional industrial wastewater constituents shall be paid by those industrial dischargers who discharge thiosulfate, volatile organic compounds, or other nonconventional industrial wastewater constituents in excess of any threshold values for such constituents as may be established from time to time by the Chief Engineer. Special charges for nonconventional wastewater constituents shall be determined by the Chief Engineer and shall be based on the appropriate Districts' sewerage system's maintenance, operation and capital expenditures for providing collection, treatment and disposal services in connection with such constituents.

Industrial dischargers subject to special charges shall perform any additional monitoring and sampling required by the Chief Engineer for the proper assessment of such charges. Such monitoring and sampling shall be performed in accordance with any other specific requirements established by the Chief Engineer for each industrial wastewater constituent subject to special charges. Special charges shall be due and payable upon service of a notice of charges as provided in Section 214, or in accordance with such other billing, reporting and payment procedures established by the Chief Engineer for each such industrial wastewater constituent.

SECTION 424 - WASTE DISCHARGE GUIDELINES

The Chief Engineer may from time to time promulgate guidelines for pretreatment systems, spill containment, centralized waste treatment facilities, flow measurement, rainwater disposal, combustible gas monitoring systems, and such other matters as he deems appropriate to effectuate the purposes of this Ordinance.
