HUSTON, CITY MANAGER FROM: PUBLIC WORKS DEPARTMENT/ENGINEERING DIVISION SUBJECT: IRVINE RANCH WATER DISTRICT PROPOSED AMENDED RULES AND REGULATIONS PERTAINING TO THE USE OF SEWERAGE FACILITIES RECOMMENDATIONS: Receive and file. BACKGROUND: Irvine Ranch Water District (IRWD) provides water distribution and wastewater collection and treatment services to residential, commercial and industrial users in portions of the City of Tustin. In order to protect the environment, as well as IRWD wastewater treatment system facilities and the health and safety of IRWD wastewater workers, the IRWD is required to adopt and implement an individual wastewater pretreatment and source control program. DISCUSSION: Pursuant to the authority provided by the California Government Code, the IRWD has drafted a document containing provisions for the regulation of wastewater discharges directly into the District's sewerage facilities in order to comply with both Federal and State policies and requirements. These rules and regulations establish quantity and quality limitations on all wastewater discharges which may adversely affect the District's sewerage systems processes or effluent quality. The proposed regulations address such discharges as storm water run-off, self -regenerative water softeners and demineralizers, and septic tank wastes. Further, the document addresses the issuance of permits by application to all significant industrial users. There are also provisions regarding enforcement of the regulations, which would allow the District to establish penalties for violation of the proposed rules and regulations and to obtain remedies for non-compliance. It is the intent of the proposed limitations to improve the quality of wastewater being received for treatment. The attached document further details the proposed regulations. Written comments will be received by the District until June 8, 1992. A public hearing will be held on that date at 6:00 p.m. where comments will also be accepted. Upon review by staff, it has been determined that the proposed regulations are primarily geared towards industrial use .and no action by the City is necessary at this time.. Robert S.

IRVINE RANCH WATER DISTRICT Attachment IRVINE RANCH .TER DISTRICT 1 Section 7 2 3 USE OF DISTRICT SEWERAGE FACILITIES 4 5 6 7.1. GENERAL 7 8 The provisions established below shall pertain to all discharges 9 into any. District sewerage collection facility that either 10 directly or indirectly transports wastewater to the District's it Reclamation Plant. A 12 13 Pursuant to the authority provided by California Government Code 14 Section 54739, 54740, and by other applicable provisions of law, 15 provisions are made in this document for the regulation of 16 wastewater discharges into the District's sewerage facilities in 17 order to comply with Federal and State of California policies and 18 requirements and to permit the District to meet applicable 19 standards of treatment plant effluent quality. These Rules and 20 Regulations establish quantity and quality limitations on .all 21 wastewater discharges which may adversely affect the District's 22 sewerage- systems, processes, or. effluent quality. It is the 23 intent of these limitations to improve the quality of wastewater 24 being received for treatment; an implication of this intent is the 25 District's policy of discouraging an increase in the quantity 26 (mass emission) of waste constituents being discharged. This 27 document also provides for regulation of the degree of waste '28 -pretreatment required, the issuance.of permits including those for 29 wastewater discharge connections, and the. establishment of 30 penalties for violation of these Rules and Regulations. 31 32* Since the District is committed to a policy of wastewater 33 renovation and reuse in order to provide an alternate, source of 34 water supply, the renovation of wastewater through secondary and 35 tertiary wastewater treatment processes may necessitate -more 36 stringent. quality requirements on wastewater dischargers than 37 those required by other governmental regulatory agencies. 38 39 The District has joined the County Sanitation Districts of Orange 40 County (CSDOC) in order to secure, an alternate method of sewage 41 treatment and disposal. To accomplish the administration of this 42 union within the portion of the District that is within County 43 Sanitation District 14, the District entered with CSDOC., into a 44 Memorandum of Understanding effective February 11, 1987, to 45 provide for cooperative implementation.* of these Rules and 46 Regulations and the ordinance of the County Sanitation Districts '47 of Orange' County as part of its regulations. In the event of a 48 conflict between the District's Rules and Regulations and CSDOC's 49 ordinance, CSDOC's ordinance shall have precedence, unless the 50 District's Rules and Regulations are more stringent. The CSDOC Hearing Draft .7- 1 IRVINE RAMC' ITER DISTRICT 1 ordinance is also applicable in areas of the District that are 2 within other County Sanitation Districts. Similarly, the area of 3 the District within the service area of the Aliso Water Management 4 Agency (AWMA) is subject to AWMA's discharge regulations as 5 adopted by the District, and the area discharging to the Chiquita. 6 System of Santa Margarita Water District (SMWD), the Portola Hills 7 area, is subject to SMWD's discharge regulations as adopted by the 8 District. In each case where dischargers are subject to the 9 discharge regulations of two agencies, it is the responsibility of 10 the discharger to meet the discharge requirements of both 11 agencies. 12 - 13 7.2.

This application shall be accompanied by the applicable fees, plumbing plans, a detailed analysis of the alternatives for disposal, or other data -needed by the District -for review. Discharge conditions and limitations shall be no less stringent than Section 7.3 of these Rules and Regulations and Section 2.7.7 of the CSDOC Ordinance. Monitoring requirements contained in the Special Purpose Permit for contaminated .groundwater .shall be for those non -compatible pollutants known to exist in the discharge and at least one analysis prior to sewer discharge shall* be performed for all constituents contained in the most current Environmental Protection Agency (EPA) "Priority Pollutant" list, excluding Asbestos. 7.4.11. MONITORING Management of a pollution control program requires a constant flow of information on the quantity and quality of discharges into the District's sewerage facilities. The monitoring of discharges serves three specific purposes. These purposes include ascertaining compliance with the Rules and Regulations, completion of necessary discharge reports as required, and determination of user charge fees. There are several modes of a monitoring program. Self Monitoring develops a data base, .and provides the necessary information for calculation of user charges. This monitoring is performed.by the user: Scheduled Monitoring is a systematic sampling and inspection survey of all industrial contributors to.the District's sewerage facilities in accordance with a predetermined'schedule. Unscheduled Monitoring is a random spot check of users to ascertain permit compliance. Demand Monitoring is conducted when some disruption of -the District's sewerage facilities develops. The District will perform scheduled, unscheduled and demand monitoring to ensure compliance with the provisions of the Rules and Regulations and permits, and .will review self-monitoring reports.. 7.4.12. SELF-MONITORING Users required to obtain a Wastewater Discharge Permit may be required to develop a self-monitoring and reporting program. The frequency of self-monitoring and reporting.will be based on the following criteria as evaluated by the District: (1) The effect of thedischarger's wastewater on the District's sewerage facilities; Hearing Draft 7- 24 1 2 3 4 5 6 7 8 9 10 it 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33' 34 35 36 37 38 39 40 41 42 43 44 45 46 .47 48 49 .50 IRVINE RANCF TER DISTRICT (2) The degree of. toxic materials which may pass through the treatment plant; (3) The need to ensure that any pretreatment standards are met; (4) The size, nature, and type of the industrial wastewater discharge; (5) The extent to which the user could contribute to violation of the District's discharge requirements. Self-monitoring programs include, at minimum, the following: a) A minimum of four (4) grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organics. b) For all other pollutants, 24-hour composite samples must be obtained through flow -proportional composite sampling techniques where feasible. C) Where flow proportional composite sampling is infeasible, samples. may be obtained through time - proportional composite sampling techniques or through a minimum of four (4) grab samples where the User demonstrates that this will provide a 'representative sample of the effluent being discharged. - Samples collected shall be in accordance with proper sampling and handling techniques outlined in the latest edition of "Standard Methods" or that publication entitled "Methods for Chemical Analysis of Water and Wastes" published by the EPA, or other appropriate method approved by the Regional Board.. _ 7.4.13. MONITORING AND METERING'FACILITIES The General Manager may require the user to construct at his own expense monitoring and metering ,`facilities "to allow inspection, sampling and flow measurement of the sewage or internal drainage systems. The General Manager may also require sampling and metering equipment to be provided, installed and operated at the user's expense. The monitoring and metering facility should normally be situated on the user's premises. When such a location would be impractical or cause undue hardship on the user, the user may construct such facilities in the public right-of-way provided said user has obtained any and all permits required therefor and that such equipment is located so that -it will not be obstructed by landscaping or parked vehicles. If the monitoring and metering Hearing Draft r 7- 25 IRVINE RAMC, ATER DISTRICT 1 facility is inside the user's fence, there shall be accommodations 2 to allow access for District personnel, such as a gate secured 3 with a District lock. There shall be ample room in or near such 4 monitoring and metering facility to allow accurate sampling and 5 compositing of samples for analysis. The monitoring and metering - 6 facility and sampling and measuring equipment shall be -maintained 7 at 'all times in a safe and proper operating condition at the 8 expense of the user. Whether constructed on public or private 9 property, the monitoring and metering facilities shall be provided 10 in accordance with the District requirements. and all applicable 11 construction standards and specifications. Construction shall be 12 completed within ninety days following written notification by the 13 General Manager, unless a time. extension is otherwise granted by 14 the General Manager. 15 16 7.4.14. INSPECTION AND SAMPLING 17 18 The District shall inspect the wastewater generating and disposal 19 facilities of any user to ascertain whether the intent of these 20 Rules and Regulations is being met and the user is complying with 21 all requirements. Persons or occupants of premises where 22 wastewater is created or discharged shall allow the District or 23 its representatives ready access during the normal working day to 24 all parts of the wastewater generating and disposal facilities and 25 monitoring and metering facilities for the purposes of inspection 26 and sampling. The District shall have the right to set up on the 27 user's property such devices as are necessary to conduct sampling 28 or metering operations. Where a user has security measures in 29 force, the user shall make necessary arrangements so that 30 personnel from the District will be permitted to enter without 31 delay for- the purpose of -performing their specific 32 responsibilities. 33 34 7.4.15. DISCHARGE REPORTS 35 36 An industrial user discharging or proposing to discharge sewage 37 into the District's sewerage facilities shall be required to file 38 discharge reports periodically or at anytime requested by the 39 District. Industrial users subject to - Federal categorical •40 pretreatment -standards, shall submit to the District by June 30 41 and December 31, unless required more frequently by the standard 42 or by. the District, a report indicating the nature and 43 concentration of pollutants in the discharge which are limited by 44 such categorical pretreatment standards.. Reports generated by 45 CSDOC may serve to meet this requirement. In addition, this 46 report shall include a record of flows as required by the 47 District. The District may agree to alter the months during which 48 the reports are to be submitted -based on an industrial user's high 49 or low flow rates, holidays, -budgets, etc. 50 Hearing Draft 7- 26 IRVINE RANCE ATER DISTRICT 1 Where the District has imposed mass limitations on an industrial 2 user, the report shall indicate the mass of pollutants regulated 3 by the pretreatment standards in the discharge of the industrial 4 user. Where 'the District has imposed .equivalent' mass or 5 concentration limits on' an industrial user,, the .report shall 6 contain a reasonable measure of an industrial user's, long term 7 production rate. For all other industrial users subject to 8 categorical pretreatment standards expressed in terms of pollutant 9 discharge per unit of production, the report shall include the 10 _ industrial user's actual average production rate for the reporting 11 period. 12 ' 13 The District may also require an industrial user to include other 14 information in the report including, but not limited to hours of 15 operation, number and classification of .employees, and quantities 16 of liquid or gaseous materials stored on site even though they may 17 not be discharged. Industrial users who monitor more frequently 18 than required by permit must report the results of such 19 monitoring. 20 21 Industrial users required to submit these reports or to keep other 22 records under the conditions of their permit shall retain for 23 three years all records of monitoring activities including *dates,, 24 times, exact places, methods, names of persons who sampled and 25 analyzed the. discharge, and results of analysis, and shall make 26 such records available for inspection and copying by the Regional 27 Board, and the District. This period of retention may be extended 28 during the course of any unresolved litigation regarding the User 29 or the District, when requested by the Regional Board. 30 31 These reports shall be signed per Section 7.4.20 of the Rules and 32 Regulations. 33 34 7.4.16. CONFIDENTIAL INFORMATION 35 36 All information and data on a user obtained from reports, 37 questionnaires, permit applications, permits, monitoring programs, 38. and from inspections shall be available to the public or other 39 governmental agencies without restriction unless the user 40 specifically requests confidentiality and is able to demonstrate 41 to the satisfaction of the General Manager that the release- of 42 such information would divulge information, processes or methods 43 which would be detrimental to the user's competitive position. 44 Any such. claim must be asserted at the time of submittal of the 45 information by stamping the words confidential business 46 information" on each page containing such information. If a claim 47 is so asserted the District will treat the information -in 48 accordance with Chapter 40, Codd of Federal Regulations, Part 2. 49 When requested by the person furnishing a- report or other 50 document, the portions of a report or document which might 7 27 Hearing Draft 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 IRVINE RANC ATER DISTRICT disclose trade secrets or secret processes shall not be made available to the public, but shall be made available to governmental agencies; and such portions of a report or document shall be subject to use by the state or any state agency in judicial review or enforcement proceedings involving the person furnishing the report or document.

TOXIC SOLID WASTES Industrial dischargers .identified as generators 'of toxic solid wastes shall be notified by the District of applicable requirements promulgated under the Solid Waste Disposal and- ne the Resource Conservation and Recovery Act (RCRA) and hall referred to the State of California Department of Health Services. The foregoing provision shall . in, no way relieve the discharger of full responsibility for ascertaining and complying with all such requirements. 7.4.18. HAZARDOUS WASTE DISCHARGE All industrial dischargers are required to file a one time notification with the District of the discharge of wastes which-, if otherwise disposed of., would be considered RCRA hazardous wastes. , Industrial dischargers which discharge more than .220 pounds (100 kilograms) of RCRA classified wastes per month must include in the notification an identification of hazardous constituents, estimates of mass and concentration on a monthly basis for twelve consecutive months. Industrial dischargers who discharge less than 33 pounds (15. kilograms) per month of non- acute- hazardous waste as defined by RCRA do not have to report under this Section. In addition, industrial dischargers need not report pollutants already addressed under self-monitoring, baseline monitoring, and other periodic compliance reports.._ Industrial dischargers subject to this Section are required to certify that they have developed a program to reduce the volume or toxicity of hazardous wastes generated to the degree it has been. determined to be economically practical. 7.4.19. BASELINE*MONITORING REPORTS All dischargers may be required to comply with applicable mandatory toxic waste and pretreatment standards promulgated Water accordance with Sections mand 308- of t he Pollution Control Act, or amendments thereto. Within 180 days of the date such pretreatment standards are promulgated, or become applicable to -the discharger, dischargers subject to the standards shall submit a baseline monitoring report to the District and to Hearing Draft 7 28 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47� 48 49 50 IRVINE RANCI ►TER DISTRICT the U.S. Environmental Protection Agency detailing, in accordance with Section 403.12, Chapter 40, Code of Federal Regulations, as amended, the dischargers compliance status with the regulations.

Progress reports, monitoring and reports of compliance shall also, as required by Section 403.12, be submitted by the discharger at the specified times. 7.4.20 SIGNATORY REQUIREMENTS Is All reports and permit applications required by the District for satisfying Federal Regulations shall contain the following certification statement: "I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with Federal Pretreatment Requirements." This statement shall be signed by a manager and the person responsible for environmental matters of the industrial user as defined in 40 CFR 403.12 (1) (1-4) . 7.5. CHARGE FOR USE 7.5.1. GENERAL The purpose of a charge for use is to insure that each recipient of sewerage service from the District pays- its reasonably proportionate share of all the costs of providing that sewerage service. Charges for use shall be used to recover the total cost of operation and.maintenance, - including the conveying, treating and disposing -of wastewater in the District's sewerage facilities,_ capital expenditures and reserve requirements for providing wastewater collection treatmentand disposal. In addition, they will be used. to* reimburse District for the -cost of monitoring and enforcement of these Rules and Regulations.. General charges will be determined on the basis of the volume of wastewater, the mass of BOD, and the mass of SS as set. forth below. Additional fees will be levied by the District for compatible or non -compatible pollutants in excess of those amounts specified in the user permit. 7.5.2. -DETERMINATION OF FLOW There are three methods for determining the volume of wastewater discharged into the sewer: direct measurement, metered water supply, adjusted metered water supply. Those users exceeding 10% Hearing Draft Zy IRVINE RANCI .TER DISTRICT 1 of the design capacity of any District sewerage facility may be 2 required to provide a continuous" automatic total flow measurement 3 system incorporating flow indication, totalization, and recording 4 of the wastewater flow (direct measurement system). Those users 5 not required to have a continuous wastewater flow measurement 6 system shall use metered water supply or adjusted metered water 7 supply measurements to determine flow. The District shall approve 8 the method of wastewater flow measurement to be used in each 9 instance. 10 11 7.5.2.1. Direct measurement reports the volume of industrial 12 wastewater determined by a full time flow meter, measuring the 13 wastewater leaving the plant. 14 15 7.5.2.2. Metered water supply reports the amount of industrial 16 wastewater discharged when the flow volume is a measurement of the 17 total water entering the user's plant. This amount can be taken. 18 from water bills or flow measuring device which measures the 19 intake of water from either the District, water wells, or other 20 sources. 21 22 7.5.2.3. Adjusted metered water supply reports the amount of 23 industrial wastewater discharged when amounts of water consumed in 24 plant operations are subtracted from the total volume of metered 25 water entering the plant. This results in a calculated rather 26 than a measured flow volume of industrial wastewater leaving the 27 plant. The adjusted metered water supply -is determined by 28 deducting measured quantities of water consumed in plant 29 operations from the metered water supply. 30 31' 7.5.3. DETERMINATION OF BIOLOGICAL OXYGEN DEMAND (BOD) AND '32 SUSPENDED SOLIDS (SS) FOR CHARGE FOR USE 33 34' (1) The BOD and SS concentrations, required for charge for 35 use will be determined from the average of six samples. 36 _ Each sample shall -be a 24, hour composite collected 37 proportional to flow. Each 24 hour composite sample must 38 have individual samples taken at least once per hour 39 during. all 24 hours -or any lesser number of hours that 40 wastewater is flowing into the sewer. 41 42 43 (2) The samples collected shall be in accordance with proper 44 sampling and handling techniques outlined in the latest 45 edition of "Standard Methods" or that. publication 46 entitled "Methods for Chemical Analysis of Water and 47 wastes", published by the EPA or other appropriate 48 methods approved for use by the Regional Board. Samples 49 collected shall. be delivered to a California State 50 Certified Laboratory for. analysis within the holding Hearing Draft 7 30 IRVINE RANC: ITER DISTRICT 1 period of the sample. The District may require samples 2 to be split for concurrent analysis. 3 4 7.5.4. CHARGE FOR USE 5 6 The charge for use for Class II users shall be computed by the 7 following formula: 8 9 Charge for use = VRv + BRb + SRS 10 11 Where V = total volume of flow, in hundred cubic feet 12 13 B = total discharge of biochemical oxygen demand, in 14 pounds 15 16 S = total discharge of suspended.solids, in pounds 17 18 Rv,Rb,Rs = unit charge rates for volume, BOD, and 19 suspended solids, respectively, adopted and. 20 adjusted as needed by the District Board of 21 Directors as shown in Exhibit B, Schedule of Rates 22 and Charges. 23 24 Each unit rate shall be based on the amount attributable to the 25 respective component as a proportionate share of the total cost 26 for operations and maintenance, capital expenditures, debt 27 service, and reserve requirements for providing wastewater 28 collection, treatment, and disposal in dollars per unit. Other 29 measurements of the. organic content of the wastewater of a 30 discharger, such as COD or TOC may be used instead of BOD when BOD 31 is not applicable. However, the discharger must establish for the 32 District a relationship between the BOD of his wastewater and the 33 other measured parameter to convert the other parameter to an. 34 equivalent BOD. This relationship shall be used by the District. 35 in determining the charge for use. When wastewater from typical 36 domestic use facilities is discharged separately from the other 31 wastewaters of a discharger, the charge for use for discharging 38 the domestic wastewater may be determined by using the following: 39 39(1) 10,000 gallons per employee per year; and, 41 42 (2) 20 pounds of suspended solids per employee per year; 43 and, 44 45 ( 3 ) 20 pounds of BOD per . employee per year. (The number of 46 employees will be considered at the average of people .47 employed full time on a daily basis. This may e 48 determined by averaging the number of people employed at 49 the beginning and ending of each quarter, or other period 50 that reflects normal employment . f luctuati.ons . ) 7- 31 Hearing Draft 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 '41 42 43 44 45 46 47 48 49 50 IRVINE RANC; ,TER DISTRICT 7.5.5. SPECIAL PURPOSE DISCHARGE PERMIT CHARGE FOR USE A charge for use to cover all costs of the District for providing sewerage service and monitoring shall be established by the General Manager. A deposit determined by the General Manager to be sufficient to pay the estimated charges for use shall accompany the Special Purpose Discharge Permit application, and said deposit shall be applied to the charges for use. 7.5.6. MASS EMISSION RATES - RATE DETERMINATION Maximum mass emission rates for non -compatible or compatible pollutants that are present or.anticipated in the user's wastewater discharge shall be set for each user and made a part of each user's permit. These rates shall be based on Federal pretreatment standards and rates, or the rates contained in Exhibit B. Schedule of Rates and Charges, to these Rules and Regulations, as applied pursuant to Section 7.5.4, whichever is more stringent. 7.5.7. CHARGES FOR NON-COMPLIANCE Non-compliance with permit requirements, mass emission rate limits, concentrations, and/or these Rules and Regulations may be determined by an analysis of a grab or composite sample of the: discharge of a permittee. If routine sampling of the discharge of.a permittee reveals non- compliance by the permittee with the mass emission rates or other conditions and limitations specified in the permittee's discharge permit, or with any provisions of these Rules and Regulations, then the permittee shall pay fees to the District as specified in. Exhibit B, Schedule of Rates and Charges. The purpose of the -non- compliance fees is to compensate the District for additional costs of sampling, monitoring, laboratory analysis, treatment, disposal; and administrative processing incurred as a result of the non- compliance, and shall be in addition to and not in lieu of any penalties as may be assessed pursuant to Sections 7.6.2, 7.6.3, and 7.6.4, and charges under Section 7.5.8. Upon discovery of non-compliance with any pretreatment standard .-and- requirement, the District shall be authorized to immediately proceed with enforcement action against the industrial user as outlined in Section 7.6. The user's status shall remain in violation until all necessary steps have been taken to restore or. achieve compliance. 7.5.8. DAMAGE TO FACILITIES* OR INTERRUPTION OF NORMAL OPERATIONS Hearing Draft " IRVINE RANCH LATER DISTRICT 1 2 When a discharge of wastes causes an obstruction, interference, 3 damage, or any other impairment to District's operation or 4 facilities the District may assess a charge to the discharger for 5 the work required to clean or repair the facility or costs 6 incurred to resume normal operations and such discharge shall be 7 grounds for permit revocation. A service fee of 25 percent of 8 District's costs shall be added to thesecharges and shall be 9 payable within forty five (45) days of invoicing by the District. 10 11 If it can be shown that the discharge is the cause of the District 12 violating its discharge requirements established by any Regulatory 13 Agency or incurring additional expenses or suffering losses or 14 damage to the sewerage facilities,- thenthat discharger shall be 15 responsible for any costs or expenses incurred by the District, 16 including regulatory fines, penalties, and assessments. made by 17 other agencies or a court. 18 19 7.6, ENFORCEMENT 20 21 7.6.1. DUTY OF ENFORCEMENT 22 23 (1) The General Manager is hereby charged with the duty of 24 enforcing this Section.
