Home My WebLink About17 - San Joaquin ReservoirITEM " TO: Members of the Newport Beach City Council FROM: Dave Kiff, Deputy City Manager SUBJECT: Ownership Transfer and Joint Statement of Objectives - San Joaquin Reservoir RECOMMENDED Authorize the Mayor to execute all documents necessary to consummate the sale ACTION: of the City's ownership interests in the San Joaquin Reservoir to the Irvine Ranch Water District (IRWD) and to approve the Joint Statement of Objectives with IRWD relating to the Newport Bay Watershed. BACKGROUND: The San Joaquin Reservoir stands empty today in the hills just east of Newport Beach's city limits. When it was last in operation in the early 1990s, it held about 3,050 acre feet of potable water (an acre foot is the amount of water needed to cover an acre of land with one foot of water). The Reservoir is owned by eight parties, including: Owner Irvine Ranch Water District Mesa Consolidated Water District City of Huntington Beach Metropolitan Water District Laguna Beach County Water District The Irvine Company South Coast Water District City of Newport Beach Percentage Ownership 47.90% 19.11% 13.11% 9.84% 5.12% 2.10% 1.64% 1.18% San Joaquin Reservoir — 1993 Newport Beach City Council Page 2 By 1995, a series of problems - including infestations of midge flies and African clawed frogs, a massive landslide and new regulations at the State level requiring reservoir covers on potable reservoirs - caused the owners to re- evaluate the use of the Reservoir. Because improvements to the Reservoir's ability to store potable water would exceed $32 MN, 1RWD has proposed using the facility to store tertiary- treated reclaimed water (RW). Reclaimed Water. 1RWD is one of the State's leaders in the production and use of RW. Residents, government agencies, and businesses throughout the District's boundaries - including all of Irvine and portions of Lake Forest, Tustin, Santa Ana Heights, and Newport Coast use RW for landscape irrigation, cooling systems, and several other non - potable uses. Reclaimed water typically sells for less than potable water, with 1RWD selling RW at $250/ acre foot, while the price for potable water is about $279 /acre foot. The District produces the RW at its Michelson Operations Plant adjacent to San Diego Creek near Michelson and Harvard in Irvine. Tertiary- treated RW goes through four separate treatment operations: (1) Removal of settle -able solids, (2) Removal of soluble organics, (3) Filtration, and (4) Disinfection. 1RWD can produce about 15 million gallons per day ( "mgd ") of RW from the Michelson Plant. RW Demand exceeds 26 mgd in the summer months, but it reaches only about 5 mgd in winter months. As noted above, during most winters 1RWD produces more RW than it can distribute. As such, it stores the water in one of two RW storage facilities - the Sand Canyon Reservoir near Turtle Rock (Irvine) and the Rattlesnake Canyon Reservoir in the foothills north of Irvine: During significant rain events, 1RWD can discharge RW from Sand Canyon Reservoir into San Diego Creek (which drains into Newport Bay) under a permit authorized by the California Regional Water Quality Control Board, Santa Ana Region ( "Regional Board "). This permit is known as Order 94-22. Order 94 -22. Order 94-22 allows discharges from Sand Canyon during "a catastrophic, chronic, or cumulative storm event (rainfall occurring over a 7 -day period or less which is equivalent to that from a 25 -year, 24 -hour storm event)." A 25 -year, 24 -hour storm event equals about 5" of rain. The Regional Board reports that Sand Canyon has discharged 6 times in 22 years due to this type of storm event - in 1980,1983,1991, 1992,1993, and 1997 -98. Any discharge of RW into San Diego Creek and Newport Bay is a sensitive issue for residents of Newport Beach, since many in Newport believe that any point - source discharge of reclaimed water into the Bay degrades the Bay's water quality. A point - source discharge (a sewage treatment plant's ocean outfall, for instance) is one that is identifiable and can often be regulated. A non -point source discharge (urban runoff) is less identifiable and therefore harder to track and regulate. Page 3 Wetlands Water Supply Project. In 1995 -96, the City opposed IRWD's Wetlands Water Supply Project (WWSP), a proposal that would have diverted up to 5 mgd of reclaimed water from the Michelson Plant into a series of marshes adjacent to the Plant. Once the water passed through the marshes (over a 7 -day detention period), 1RWD proposed releasing it into San Diego Creek. WWSP envisioned a 2 -year demonstration phase and a subsequent permanent phase. 1RWD received permits from the Regional Board (Orders 96 -2 and 96 -3) to implement WWSP. At the time, the City - along with the Chamber of Commerce, the Balboa Island Improvement Association, and other groups including a new advocacy group called "Defend the Bay" - argued that the point- source discharge of RW into the Creek and Bay could impair the Bay's health in a number of ways, including adding nitrogen to the Bay and by potentially adding a variety of contaminants associated with the reclamation process. 1RWD disputed most if not all of the City's assertions, arguing that RW had far less impact to the Bay than the urban runoff and nuisance flows contained in San Diego Creek. Readers who wish to know more about the 1996 WWSP can review the Final Environmental Impact Report (E1R No. 95011047). The document is available at the Newport Beach Public Library. Basic Integrated Re -Use Project. The City's opposition to the WWSP led it to propose a Basic Integrated Re-Use Project (B1RP) to attempt to address 1RWD's wintertime oversupply of RW. The B1RP proposed, among other things: — GAP I1. Green Acres Phase 11 envisioned the construction of a new 7.8 million gallons per day (mgd) pipeline from the Orange County Water District (OCWD) to an Intertie pipe (see below) coming from 1RWD's Michelson Operations Plant. lntertie. The lntertie is a 7.8 mgd pipe that goes from the Michelson Operations Plant to the end of GAP 11's pipe. OCWD's Acceptance of Wintertime Flows. OCWD would accept at least 4.6 mgd and up to 7.8 mgd of 1RWD's excess RW between October 1 and March 31 as long as the Orange County Sanitation District (OCSD) agreed to take at least 4.2 mgd of the OCWD RW which OCSD would use instead of secondary - treated RW. City End -User Agreements. The City would commit to entering into agreements with major purchasers of RW within the City (including the Big Canyon Country Club and the Newport Beach Country Club). BIRP is in place today. In the Agreement which set the B1RP in motion (dated July 17,1996), IRWD and the City proposed a Long -Term No Discharge Scenario whereby 1RWD and the City would use their "best efforts" to avoid any RW discharge into the Bay. Included in the Scenario was the goal to work together towards a permanent water source to irrigate the marsh system. San Joaquin Reservoir and the Toint Statement of Objectives. As noted, the Reservoir has a historic capacity of about 3,050 acre feet of water. 1RWD believes that it can add the San Joaquin Reservoir to its existing RW storage system (including Sand Canyon and Rattlesnake Canyon) to manage 1RWD's wintertime excess RW to reduce the need for future new point- source discharges of RW into San Diego Creek except under the extraordinary circumstances described in Page 4 Order 94 -22. The City agrees that adding the capacity of the SJ Reservoir will greatly reduce any need on 1RWD's part to discharge and therefore supports its conversion. The City is the only ownership partner of the SJ Reservoir that has not yet consented to the transfer of its ownership to 1RWD. In anticipation of this transfer, City representatives have met with IRWD over a series of months to develop a Joint Statement of Objectives that would help identify and make public the ways in which the City and 1RWD will cooperate to reduce or eliminate point- source discharges of RW into the Bay. These include: Continued and permanent diversion of San Diego Creek water into the marsh system to limit nitrogen inflows into the Bay. — Sediment removal in Campus -area catch basins to implement the Sediment Total Maximum Daily Load (TMDL). Effective operational management of the San Joaquin Reservoir to minimize impairments to the neighboring residential communities. — Seeking additional ways to use surplus RW outside of the San Diego Creek watershed, including the continuation of the Green Acres Project, the OCSD outfall, and the lntertie. Promotion of water conservation throughout the region. Greater public access to information, including to 1RWD's operational data associated with its RW storage network. Participation in future water quality studies involving Newport Bay. Promotion of additional uses for RW, including possible expansion into Newport Beach's Harbor Ridge community. Compliance with existing orders and permits of the Regional Board, specifically Order 94-22 relating to Sand Canyon overflows during extraordinary rain events. Transfer Documents and Sale Price. if the City Council agrees with the recommended action, the Council will authorize the Mayor to transfer the City's approximate 1.18% ownership right in the San Joaquin Reservoir to 1RWD for $360/ acre feet of ownership (about $13,000). Any transfer of ownership rights also includes a transfer of any liability obligation on the City's part for the future use of the Reservoir. City staff believes that this $13,000 sum should be used in part to support and monitor the Joint Statement of Objectives. 1RWD staff has told us that transfer documentation (to be signed by the Mayor when these documents are prepared) will include language which would negate the transfer and return the City's ownership share to the City should 1RWD choose at a later date NOT to convert the Reservoir to a reclaimed water storage facility. Page 5 Conversion Schedule. IRWD recently issued a mitigated Negative Declaration (ND) that describes the likely environmental impacts of the Reservoir's conversion to a reclaimed facility.

ADOPTED this 2611, Day of September, 2000. John E. Noyes MAYOR ATTEST: LaVonne Harkless CITY CLERK Page 8 Attachment B City of Newport Beach Irvine Ranch Water District JOINT STATEMENT OF OBJECTIVES FOR NEWPORT BAY WATERSHED PROTECTION September 26, 2000 The Irvine Ranch Water District (IRWD) and the City of Newport Beach (CNB) are committed to improving the water quality in the Newport Bay by, among other things, enhancing the water quality of its tributary watershed. The City, IRWD and residents interested in water quality all agree that the conversion of the San Joaquin Reservoir to a reclaimed water storage facility will greatly reduce potential reclaimed water discharges in the future. Since 1996, the City and its residents have worked to prevent new point source discharges to the Bay. The conversion of the reservoir represents a significant step towards that objective. For these reasons, the City Council intends to sell its small capacity interest to IRWD and work with IRWD to implement the conversion. IRWD is committed to operate San Joaquin Reservoir in a manner that enhances the nearby residential communities much like Sand Canyon Reservoir enhances the homes around that facility. The City and IRWD also support and will promote the increased use of reclaimed water as an alternative to importing potable water supplies. By increasing the year -round demand for reclaimed water, the City and IRWD will increase the beneficial use of reclaimed water - an important goal of the State - while further reducing the potential for future new point source discharges of reclaimed water into San Diego Creek. IRWD, the City and the scientific community disagree as to the environmental impacts of routine wet season reclaimed water discharges into San Diego Creek and Upper Newport Bay. However, IRWD and the City acknowledge the importance of continuing to strive for a balanced, scientifically sound approach to managing all potential sources of water quality impairment in Upper Newport Bay. By adopting this Joint Statement, the City and IRWD support implementation of the following measures that are designed to improve water quality throughout Newport Bay and its watershed. San Diego Creek Urban Runoff Diversion and Treatment: The agencies acknowledge that existing diversions of San Diego Creek through the marsh system have resulted in substantial nutrient reduction and improvement in the overall quality of water returning to San Diego Creek and ultimately Upper Newport Bay. To further improve San Diego Creek water quality, IRWD plans to construct improvements to expand the capacity of the San Diego Creek diversion system and protect the facility from siltation so that year -round diversion of creek water through IRWD's San Joaquin Marsh system can be implemented prior to the winter of 2001/02. Sediment Removal Initiatives: IRWD plans to continue to remove the sediment from the San Diego Creek in- channel basins per the existing agreement with the County of Orange. IRWD's actions will reduce sedimentation in Newport Bay. Both agencies, have in the past, and will continue to support the Newport Bay Watershed Executive Committee's programs for in -bay basin sediment removal and channel deepening. Operation of San Joaquin Reservoir: IRWD intends to construct necessary improvements and operate the San Joaquin Reservoir as a reclaimed water storage facility. IRWD plans to design and operate the reservoir to minimize odors or other potential impairments to the adjacent residential communities, and maximize reclaimed water storage during the winter when production from the Michelson Reclamation Plant exceeds demand. Both agencies acknowledge the proposed operation of the reservoir will Page 9 minimize the need for exporting surplus reclaimed water outside the San Diego Creek watershed. IRWD and the City believe the reservoir will minimize the need for IRWD to seek prospective changes in its NPDES permit to allow new point source discharges of reclaimed water into San Diego Creek in the future. Use and Disposal of Surplus Reclaimed Water Outside the San Diego Creek Watershed: Both agencies will support efforts to find additional beneficial uses and alternative means of disposal of surplus reclaimed water to projects outside IRWD and the San Diego Creek watershed area. IRWD and the City will work together to continue current deliveries of surplus reclaimed water to the Green Acres Project and the OCSD outfall. Both agencies will support renewal of agreements with the Orange County Water District and Orange County Sanitation District to continue these deliveries in the future. Both agencies will actively search for and support other regional projects that would take deliveries of surplus reclaimed water from IRWD. Water Conservation to Reduce Urban Runoff: Both agencies will continue to promote water conservation as a measure to minimize runoff in accordance with the California Urban Water Council's Best Management Practices. Public Education and Information Programs: Both agencies support and actively participate in programs to educate the public regarding practices to minimize non -point source pollution of urban runoff entering San Diego Creek and Upper Newport Bay. Both agencies support measures to provide increased public access to IRWD's reclaimed water system operating and water quality data, including placing timely operational data regarding Sand Canyon Reservoir on IRWD's website. The City and IRWD believe that increased public access to this information will confirm IRWD's full compliance with permit conditions and promote an understanding of the reclaimed water system, its overall operation, and its benefits. Upper Newport Bay Watershed Protection Research: Both agencies support and will continue their participation in current and future studies which IRWD and the City mutually develop or which are proposed to them, and which they concur will advance the sound scientific understanding of water quality problems and solutions for the watershed. Currently proposed studies include: the Regional Water Quality Control Board's ( RWQCB) watershed health risk assessment study, the RWQCB /City of Newport Beach Newport Bay pathogen source study, the RWQCB long -term monitoring program, the RWQCB Total Maximum Daily Load programs, and the U.S. Army Corps of Engineers Newport Bay Watershed Feasibility Study which will determine the hydrology and hydraulics in the watershed and sediment baseline characteristics. Promotion of Additional Reclaimed Water Irrigation Uses: Both agencies will work diligently to expand the uses and user base of reclaimed water in the San Diego Creek watershed area. The first priority will be uses that offset current potable water demands and minimize the potential for new point source discharge into the San Diego Creek. Additional reclaimed water service may include expansion into Harbor Ridge and other areas of Newport Beach where it is both cost effective and within the best interests of the City to provide such service. Compliance with Reclaimed Water Use and Discharge Regulations: IRWD and the City acknowledge that IRWD's current NPDES permit (Order 94 -22 - attached) operating restrictions and entitlements, including permitted incidental discharges, effectively meet reclaimed water quality and discharge objectives for San Diego Creek and Upper Newport Bay. As such, the agencies will actively pursue the renewal of IRWD's NPDES permit under terms so as to preserve reclaimed water supply benefits and maintain water quality protections for the community, the Newport Bay and its tributary area. Both agencies acknowledge that the continuation of the operating restrictions and entitlements of Order 94 -22 are integral to this Joint Statement of Objectives. Page 10 This Joint Statement of Objectives was approved by the Newport Beach City Council on September 26, 2000 and by the Board of Directors of the Irvine Ranch Water District on September _, 2000.

Surfrider Foundation Ken Thor son Director of Water Quality Irvine RIP. Water District 3512 Mi lson Drive Irvine; C12612-'1799 RE: Sup #prt for the conversion of the San Joaquin Reservoir to store reclaimed water Dear Ke The S Foundation, its 26,000 members,, and the Newport Beach Chapter support water recla I as a means of water conservation., .Reclaimed water is a valuable commodity that should n wasted. The Surfrider Foundation advocates the use of reclaimed water and feels that the c version of the San Joaquin Reservoir will provide extra storage and prevent the excess r production that is reclaimed from being wasted. This support is conditional on the fact that excess water will be drained out of the reservoir and into the Newport Back Bay. It has been sured to the Surfrider Foundation from the Director of Water Quality that the site is not pron spilling over due to a negligible amount of watershed. The Surb iii er Foundation is dedicated to the protection and enjoyment of the world's waves and beaches f 1, all people, through conservation, activism, research and education. In California, we have ovei 0,000 members and seventeen grassroots chapters ranging from Humboldt County to San Dieg including a chapter in Newport Beach. We find that the goals of the Surfrider Foundatid parallel those of the Irvine Ranch Water District's water reclamation program. Namely t educe the quantity of treated water used and to reduce the amount of water that is . sent of thApanitation district and discharged into the ocean. The Surb er Foundation believes it is essential that that one positive environmental action does not lead 1 another negative action and therefore we beli£v£ iat it is essential that the conversion process a I the new reclaimed water facility does not contribute treated or untreated water to the Newport I I each Back Bay. The Back Bay estuarine ecosystem is rare in California, where over 90% of o wetlands have been destroyed, and it must be protected to the utmost. Thank y for seeking the. opinion of the SurfriderToundation in this matter and we support the conversi of the.San Joaquin reservoir to a reclaimed water reservoir.

Box 1768 Newport Beach, CA 92658 -8915 IM-0 0 Re: Ownership Transfer and Joint Statement of Objectives -- San Joaquin Reservoir September 26, 2000 Regular Meeting Honorable Members of the City Council: Johnson & Edwards LLP has been retained by Defend the Bay, Inc., a California non - profit organization dedicated to protecting Newport Bay and its watershed, We have been asked to comment upon the City's proposed sale of its interest in the San Joaquin Reservoir and approval of the Joint Statement of Objectives with the Irvine Ranch Water District ( "IRWD ") regarding the Newport Bay Watershed. As we understand it, the project, as it relates to the City, entails two components. First, the City would sell its 1.18% interest in the reservoir to IRWD. Because all other entities with an ownership interest in the reservoir have already agreed to sell their interests to IRWD, IRWD would thereby have a 100% ownership interest, Second, the City would approve the Joint Statement of Objectives with IRWD, which would allow IRWD to convert the reservoir into a reclaimed water storage facility. For the reasons discussed below, any approval by the City at this stage would be in direct violation of the California Environmental Quality Act ( "CEQA "), The City is a responsible agency under CEQA and, as such, cannot approve any aspect Of the project until the necessary environmental review of the project has been completed, The City Is n "Responsible Agency" A "responsible agency" is defined as follows: "Responsible Agency" means a public agency which proposes to carry out or approve a project, for which a lead agency is preparing or has Hon. John E. Noyes, Mayor Newport Beach City Council Robert Burnham, City Attorney September 26, 2000 Page 2 prepared an EIR or negative declaration. For the purposes of CEQA_ the term "responsible agency" includes all up blic agencies other than the lead agency which have discretionary approval power over the 12rpiect. Guideline § 15381 (emphasis added); see also Pub. Res. Code § 21069. The lead agency under CEQA is "the public agency which has the principal responsibility for carrying out or approving a project which may have a significant effect upon the environment." Pub. Res. Code § 21067; see also Guideline § 15367. In this case, IRWD has apparently assumed the role of the lead agency and is preparing the mitigated negative declaration for the project. The City, however, is clearly, at a minumum, a responsible agency with respect to this project because it has "discretionary approval power over the project." Guideline § 15381. It has discretion both whether to approve the sale of its interest to IRWD and whether to approve the Joint Statement of Objectives. Accordingly, the City is a responsible agency such that its approval of the project is subject to CEQA. The Sale and Conversion of the Reservoir is a "Project„ Moreover, there can be no doubt that the sale of the reservoir and its subsequent use to store reclaimed water qualifies as a project under CEQA. "Project' is defined as "an activity which may cause either a direct physical change in the environment, or a reasonably foreseeable indirect physical change in the environment." Pub. Res. Code § 21065. The definition is refined at Guideline section I5378(a) to make clear that the activity need only have the "potential for resulting" in direct or reasonably foreseeable indirect change. The project here clearly has the potential for resulting in a direct or reasonably foreseeable indirect change in the environment The conversion of the reservoir into an unclaimed water storage facility has the very real potential for adversely harming the environment due to intentional or unintentional releases of reclaimed water, an undisputed pollutant, into the Newport Bay Watershed. In any event, whether this matter qualifies as a project is a moot point since IRWD is treating it as a project and preparing a mitigated negative declaration. Environmental Review is Required Before the City Approves the Project CEQA is very clear that a responsible agency cannot give any discretionary approval to a project until it considers the final EIR or negative declaration prepared for the project: Before granting any approval of a project subject to CEQA, every lead agency or responsible agency shall consider a final EIR or negative declaration or another document authorized by these guidelines to be used in place of an EIR or negative declaration. Guidelines § 15004(a) (emphasis added.) Hon. John E. Noyes, Mayor Newport Beach City Council Robert Burnham, City Attorney September 26, 2000 Page 3 CEQA further defines the roles of the responsible agency as requiring it to consider the effects of the activities involved in the project for which its approval is required: [T]he responsibility of the lead agency shall differ from that of a responsible agency. The lead agency shall be responsible for considering the effects, both individual and collective, of all activities involved in a project. A responsible agency shall be responsible for considering only the effects of those activities involved in a Qioct which it is required by law to carry out.or approve. Pub. Res. Code § 21002.1(d) (emphasis added). Accordingly, CEQA mandates that the City, as a responsible agency, cannot give any approval to the subject project until after it reviews the final mitigated negative declaration prepared by IRWD. The mitigated negative declaration, however, is still in draft form and still out for public review and comment. It is not yet final. Accordingly, any approval by the City at this stage would be in direct violation of CEQA. The Subject Resolution Constitutes an "Approval" We also note that the proposed resolution before the Council clearly constitutes an approval. "Approval" is defined at Guideline § 15352: (a) "Approval" means the decision by a public agency which commits the agencv to a definite course of action in regard to a project intended to be carved out by and person. The exact date of approval of any project is a matter determined by each public agency according to its rules, regulations, and ordinances. Legislative action in regard to a project often constitutes approval. (b) With private proiects. approval occurs upon the earliest commitment to issue or the issuance by the public aaencv of a discretionary contract, grant, subsidy, loan, or other form of financial assistance, lease, permit, license, certificate, or other entitlement for use of the project. [Emphasis added.] The resolution at issue authorizes the Mayor to "execute all documents necessary to implement the transfer of the City's ownership in the [reservoir] to [IRWD]" and to sign the Joint Statement of Objectives. The resolution, therefore, "commits the [City] to a definite course of action." Guideline § 15352. Accordingly, it constitutes an approval of the project. Hon. John E. Noyes, Mayor Newport Beach City Council Robert Burnham, City Attorney September 26, 2000 Page 4 The City is a responsible agency. Any approval of the subject project, therefore, must await the City's consideration of the final mitigated negative declaration prepared by 1RWD. That document, however, is not yet final. Accordingly, any approval at this stage would be in direct violation of CEQA. Sincerely, JOHNSON & EDWA . S L P W �J �Ic in K.

The three main types of non - reclaimable wastes expected in the Study Area are: (1) Excess reclaimed water (which cannot be used for irrigation or ground water recharge due to seasonal variations in demand); (2) Industrial wastes (which may be toxic or have a high concen- tration of salts); and (3) Sludges produced in the water reclamation plant. The special waste expected from phosphate removal at the reclamation plant is included as one of the industrial wastes. `EXCESS RECLAIMED WATER There will be periods of the year, especially during the months of December, January, and February where there will be an excess of reclaimed water available, averaging about 2 mgd during these three months, until 1978 (Chapter IV), increasing to about 73 mgd during storms until 1990. The peak flows during storms cannot be reclaimed economically because of the required extra capacity which would remain unused during most of the year and because spreading grounds cannot be operated at capacity during, and immediately after rains. It is likely that the excess reclaimed water can be discharged to San Diego Creek during the next.few years meeting the water quality ob- jectives established by Santa Ana River Basin Regional Water Quality Control Board (Appendix V -1). It is estimated from comparison with the composition of the present flow to Newport Bay from San Diego Creek, Table V -1, that intermittent discharge of excess reclaimed water can -ccur until about 1972 without adverse effects. However, increasing re- 'cflaimed water flows, combined with extensive development of Upper Newport Bay, may reduce the Bay's assimilative capacity and make even intermittent V -1 I" lJ. '1 LT I,.

V -2 discbarge of excess reclaimed water to the Bay undesirable. It is .`j recommended that IRWD, in cooperation with interested agencies, deter- mine the actual assimilative capacity of the Bay to obtain the most economical water reclamation system. For cost estimating purposes it is assumed all excess reclaimed water must by -pass Newport Bay after 1972. Two alternatives have been considered; construction of a direct line to the ocean, and discharge to the Santa Ana River flood control channel in the vicinity of the San Diego Freeway. The general aspects of direct ocean disposal have been discussed previously (Reference II -1). However, more economical dis- posal of excess reclaimed water may be achieved in the water reclamation plan proposed here by constructing the first part of the force main to the Santa Ana River spreading grounds in 1972 instead of 1978, terminating in the vicinity of the intersection between Santa Ana River and San Diego Freeway. The force main up Santa Ana River to the spreading grounds can then be completed when reclaimed water is available. No significant water quality problems are expected from such inter- mittent discharge of secondary effluent at that point, and it will be possible to incorporate the discharge in the proposed Santa Ana River Regional Park. Discharges of secondary effluents similar to this scheme are presently considered by the County Sanitation Districts of Los Angeles County. IND- ISTRIAL WASTES Collection: Non - reclaimable industrial wastes are expected from the planned industrial development in the eastern part of the Study Area. These wastes, possibly including concentrated phosphate wastes from the Rossmoor, Los Alisos, and E1 Toro reclamation plants, may be conveyed to the reclamation plant through a separate industrial waste line (Reference II -1) . Construction of a parallel line for industrial waste to IRWD (instead of to the Study Area boundary) will add approximately $1,300,000 of which about one -half may be saved due to deferral of one of these �i parallel lines for about 10 years.

Irvine Ranch Water District (hereinafter discharges), by applica- tion No. CA 0106844, has applied for waste discharge requirements and a permit to discharge wastes under the National Pollutant Discharge Elimination System. 2. Treated municipal wastes will be discharged, on an emergency basis, to San Diego Creek, which is tributary to Upper Newport Bay. 3. The State Water Resources Control Board adopted a "Water Quality Control Policy for the Enclosed Bays and Estuaries of California" (Bays and Estuaries Policy) on May 16, 1974. 4, The Bays and Estuaries Policy and the Water Quality Control Plan for the Santa Ana Region prohibit any new discharges of municipal wastewater to any bay or estuary unless it can be shown that such discharges will enhance the quality of the receiving waters. 5. The purpose of the proposed emergency discharge is due to several factors: Structural problems recently found at the District's Rattlesnake Reservoir now limit the storage of effluent in the reservoir to 1/3 of its design capacity. The District's remaining effluent storage at Sand Canyon Reservoir has been significantly affected by stotmwater runoff, which has resulted in significant damage from .spillway overflows to downstream facilities. As a result, wet weather storage is below necessary levels. 6. The discharger is proposing to correct the effluent wet weather storage deficiency by implementing one or both of the following projects: a. A pipeline to be constructed from the discharger's treatment plant to the County Sanitation Districts of Orange County's ocean outfall. It is anticipated that this will be completed by approximately March 1985. b. A study is currently underway to determine the feasibility of utilizing the local groundwater aquifer for effluent wet weather storage. Waste discharge requirements for this project are being processed. Order No. 81 -114 (NPDES No. CA 0106844) - continued Page 2 IRWD Emergency Stream Discharge 7. Treated municipal wastewater may be discharged through Discharge Points 001, 002, and 003 during certain stormwater runoff periods. These discharges will be made during or immediately after rain storms. 8. The discharge points are located as follows: a. Discharge Point 001: Rattlesnake Reservoir; latitude 33043'13 "; longitude 117044143 ", b. Discharge Point 002: Hicks Canyon Wash /Culver; latitude 33'43'26"; longitude 117045'57 ". C. Discharge Point 003: Sand Canyon Reservoir; latitude 33038'56"; longitude 117047'41 ". The discharges at Points 001, 002, and 003 will have received activated sludge treatment plus coagulation, dual media filtration, two -hour chlorine contact, and an indeterminate amount of storage in the District's storage reservoirs. 9. A Water Quality Control Plan was adopted by the Board on April 11, 1975. The Plan contains beneficial uses and water quality objectives of waters in the Santa Ana Region. 10.. The requirements contained in this order are necessary to imple- ment the Water Quality Control Plan. 11. The beneficial uses of San Diego Creek in the vicinity of the discharges include: a. Non - contact water recreation; b. Warm freshwater habitat; and C. Wildlife habitat. 12.. The beneficial uses of Upper Newport Bay include: a. Water contact recreation; b. Ocean commercial and sport fishing; C. Preservation of a special biologically significant area; d. Wildlife habitat; e. Preservation of rare species; f. Marine habitat; and g. Shellfish harvesting. 13. The issuance of these waste discharge requirements is exempt from the provisions of the California Environmental Quality Act (Public Resources Code, Section 21000 et seq.) in accordance with Section 13389 of the California Water Code. 14. The discharger and interested persons and agencies have been notified of the Boards intent to prescribe waste discharge require- ments for the discharge and have been provided with the opportunity for a public hearing and the opportunity to submit their written views and recommendations. 15. The Board, in a public meeting, heard and considered all comments pertaining to the discharge.

It should be noted that this flow was an estimate based upon the height of water flowing in the spillway, the estimated water velocity, end the width of the spillway. It was further justified by flow measurements observed by UCI. b) Significant damage to IRWD facilities below the Sand Canyon spillway began to occur. This emergency condition was reported to regulatory agencies and a controlled discharge from the 24" emergency outlet located at the base of Sand Canyon Reservoir was reactivated at llx70 AM to minimize damage to downstream facilities.

The Plan contains beneficial uses and water quality objectives of waters in the Santa Ana Region- 11 . The requirements contained in this order are necessary to imple- ment the Water Quality Control Plan. 12. The beneficial uses of San Diego Creek include: a. Groundwater recharge; b. Non - contact water recreation; c. Warm Freshwater habitat; d. Wildlife habitat. 13. The beneficial uses of Upper Newport Bay include: a. Water contact recreation; b. Ocean commercial and sport fishing; c. Preservation of area of special biological significance; d. Wildlife habitat; e. Preservation of rare species; f. Marine habitat; g, Shellfish harvesting. 14. Irvine Ranch Water District has issued a negative declaration for this project. The Regional Board has reviewed the negative declara- tion and initial study and finds that this project will not cause adverse environmental impacts on water quality if conducted in accordance with the limitations and the provisions if this order. 15. The discharger and interested persons and agencies have been notified of the Board's intent to prescribe waste discharge require- ments for the discharge and have been provided with the opportunity for a public hearing and the opportunity to submit their written views and recommendatiors.

As of 4- 13 -78, the storage available is 319 AF.. This represents a total of 21 days storage based upon the Michelson plant flow of 15.3 AF per day. The detail of these figures is as follows: Sand Canyon Reservoir Rattlesnake Reservoir Duck ponds TOTAL Available Storaas AF Day ■ 136 8.9 53 3.5 130 8.5 319 20.9 Aa you mentioned to me earlier this week, The Irvine company, who is our major consumer of irrigation water, does not plan to take any appreciable amount of water until approximately May 15, 1978. Couplinq.this fact with an assumed 1" rainfall between now and May 15, 1978 a total of 570 AF (490 AF of plant production and'80 AF of rain runoff into storage) storage will be required. Based upon the facts stated above, an excess of 250 AF of storage or dischat,:i is required. There are three alternatives which can be taken. They are as followai Alternative I Raise the Sand Canyon Reservoir spillway three feet by placing sand bags and permit the water surface elevation in Rattlesnake Reservoir to rise to spill elevation 412 feet. The placement of sand bags would increase the storage capacity by 170 AF and raising the allowable water surface elevation at Rattlesnake Reservoir to the spillway would increase the amount of avail- able storage an additional 180 AF, thereby increasing the total amount of storage by 350 AF. Alternative II Allow the 250 AT excess to flow over the Sand Canyon Reservoir spillway. Alternative III Initiate controlled discharge from the emergency outlet at the base of Sand Canyon Reservoir dam. Page 2 W. H. Semple April 11, 1970 We reviewed Alternative I with the IPY;D dams and reservoirs consultant, W. A. Wahlor and Associates. They stated that raising the allowable water surface elevation in Rattlesnake Reservoir to its maximum capacity of elevation 412 feet would not be recommended duo to the uncertainties of the safety of the dam with a full reservoir ender a dynamic s t-r ess condition (earthquakes). Since they could not recommend raising the water surface elevation at Rattlesnake, this would moan that the placement of a sand bag berm in the Sand Canyon Reservoir spillway would be insufficient to accommo- date the entire amount of excess irrigation water and spillage over the berm may cause it to fail, thereby presenting a potential downstream safety hazard. Based upon W. A. Wahler's recamaendation, we recommend that this alternative be eliminated from further consideration. Alternative II is a viable method of releasing the excess water as stated herein; however, in view of the substantial amount of damage which occurred as a result of the flow over the spillway (approximately $140,000 worth of damage) during the storm and its potential for added damage if additional flows over the spillway occur, this solution sliculd be avoided if possible. It should also be noted that we have completed the repairs to the L1 Toro line at Sand Canyon Reservoir at an estimated cost of $12,000. If additional flows over the spill- way occur, this line will suffer acme damage and will possibly need additional repair. In view of the safety hazards inherent with Alternative I and the added addi- tional repairs which may be needed if Alternative II were implemented, it would only seem practical to adopt Alternative III, namely initiate controlled dis- Oarge from the 24" emergency outlet at the base of Sand Canyon Reservoir. By doing so no significant additional damage will occur to District and other related facilities. Based upon the figures stated above it is recommended that 250 Ar be released from the 24" emergency outlet. Our records indicate that the capacity of the outlet is 40 A£ par day. Therefore, the outlet must be activated for 6.25 days to accomplish this purpose. p R,CAB,wht cci C. W. Ballard Kr. Joe xulikwski, W. A. Wahlor 4 Assoc. Y. :ifs ; I nn' ..

We have begun such discharge at 8:00 AM on November 5, 1986. Flow rates will vary up to 35 cfs. Reporting of flow rates and water quality information will be provided with the monthly Michelson Reclamation Plant operational report, as required by existing permits. Several steps were taken to avoid emergency discharge including reducing reclaimed water rates to several large consumers; obtaining special permission to allow IRWD to exceed current maximum allowable storage in Rattlesnake Reservoir and construction of temporary treatment and new service connection's facilities from Rattlesnak -W Reservoir to permit expanded use of reclaimed water. These measures extended the time before emergency discharge was required; however,' since current storage at Rattlesnake is near capacity and Sand Canyon Reservoir water in storage is well into the 250 acre -foot freeboard limit, discharge has begun. Such discharges will continue until sewer flow tie -in facilities are completed with Orange County Sanitation District. These facilities will be completed by January 1987. However, it should be noted that storm flows into Sand Canyon Reservoir may require subsequent emergency discharges in the future. Sincerely, IRVINE RANCH WATER DISTRICT 51 l4 . �49� Carl W. Ballard Director of Field Operations. CWB /ld January 17, 1969 To: Mr. Osborne From: Jim Roberts Subject: Irvine Ranch Water District - Analyses of Sewage Effluent. Industrial Waste Permit No. 140 Provision 6 of Industrial Waste Disposal Permit No. 140 places limits on the quality of the effluent to be discharged as based upon an incremental increase over the existing water supply as averaged over a period of a year. The specific limitations are: Filtrable residue (dried @ 180 °C) 280 ppm, Sulfate 40 ppm, Chloride 75 ppm, Fluoride 0.5 ppm, Boron 0.5 ppm, Total hardness (CaCO3) 35 ppm, Sodium 75 ppm. Heavy metal limitations are also imposed. The Irvine Ranch Water District effluent quality is exceeding the limits prescribed in Provision 6 for Filtrable residue by p 130 ppm, Sulfate by 33 ppm, Chloride by 3 ppm, Fluoride by .8 pm and Sodium b:� 30 ppm. Therefore they are ivni olation of Industrial Waste Disposal Permit No. 140. Analyses of effluent attached. Discussion The effluent is used for irrigation within a ground water basin that contains some ground waters that are of a poorer quality than the discharged effluent. If the Irvine Ranch Water District was prosecuted for violation of Provision 6 of their Permit, it does not appear to constitute a clear case of Pollution of Underground or Surface Waters as defined in Section 43.041 and therefore we may fail to show a cause of action. If the effluent was being spread for ground water recharge purposes a more solid case would be evident. The IRWD is possibly the most progressive and concerned agency about their mineral quality within this watershed. I do not know or care to project if any legal action against the District would stimulate the enforcement activity of RWQCB #8 against other violators on the watershed. Recommendation 1. Notify Executive Officer Dick Bueermann of RWQCB #8 that the subject is in violation of their discharge requirements for which a meeting to discuss the same is suggested. H 2. Notify the subject that they are in violation of Provision 6 of their discharge requirements but do not direct in the notice that the violation be corrected Fy a specified time. The notice should question what the District intends to do to comply with the permit with a reply within 60 days requested. 3. Discuss the Notice of Violation and enforcement of same with County Counsel. `XJ A"- ^ &Jim Roberts JR:np Attachments: Effluent Analyses I JUP� i G iSo7 To: Mr. Osborne From: .Jim Roberts Subject: Irvine Ranch Water District - Permit No. 140 Manager Bill Eppinger stated in a recent conversation that plans are to pump surface flows from San Diego Creek together with effluent from their treatment plant to Sand Canyon Reservoir. There are elec- trical standby charges to the district s treatment plant so the pump- ing of San Diego Creek surface flows will be at no extra cost other than maintenance on the pumps. Analyses of the water flowing in San Diego Creek as sampled 2570' NE of MacArthur Boulevard are as follows: Est. Date Flow E.C. Cl NO PO TDS Calculated 11 -23 -66 5 cfs 3700 micro- 457 ppm 32 ppm 1 ppm 2590 ppm mhos 12 -28 -66 4 cfs 5350 " 755 " 60 " 1 " 3745 " 1 -23 -67 13 " 1020 " 95 " 11 4 " 714 " 3 -02 -67 4 " 5980 837 " 46 " .2 " 4186 " 4 -04 -67 7 " 4620 " 596 " 61 .25 3234 " micro- Average 6.6 cfs 4134 mhos 548 ppm 42 ppm 1.3 ppm 2894 ppm The average flow within San Diego Creek when samples were taken was 6.6 cfs or 4,265,976 gallons per day. Designed flow of the treatment plant under construction is 2 million gallons per day with predicted flows by their consultants of 10.0 m.g.d. in 1990. Design capacity for the force main from the treatment facility to Sand Canyon Reservoir is not known. Industrial Waste Permit No. 140 issued by this department to the subject allows an incremental increase in specific chemical constituerrs over the water supply. The quality of reclaimed water from the IRWD is expected to be similar to that of Rossmoor Sanitation Inc. whose latest analyses shows a chloride level of 200 ppm and a TDS of 1050 ppm. A copy of Rossmoor's analyses is attached. It was earlier learned that initial flows to the plant will ,be 500,000 gallons per day beginning sometime in September of this ,.'year. y Assuming the force main to Sand Canyon Reservoir will handle all of the averaged sampled flow from San Diego Creek together with the initial treated sewage flow thus producing a hypothetical water as follows: Plow E.C. Cl N0-1 TDS 7.2 mgpd 385.8 511 42.7 .2698 This hypothetical water is undesirable for irrigation purposes because of the high chloride and total dissolved solids concentrations. There will be a certain dilution factor when this hypothetical water is discharged to Sand Canyon'Reservoir which will contain storm runoff of an unknown quality and Variable quantity. This combined water is not expected to be used for ground water recharge practices in any significant amounts, but rather for irriga- tion purposes on selected crops. The leaching factor for use of these waters to maintain a favorable salt balance within the root zone may be as high as 50 %. U.S.D.A. publication, "Diagnosis and Improvement of Saline and Alkali Soils" Page 72, Table 10 shows the following leaching requirements: TABLE 10. -- Leaching requirementl as related to the elec- trical conductivities of the irrigation and drainage waters Leaching requirement for the indicate maxi - Electrical mum values of the conductivity of the drain - conductivity age water at the bottom of the root zone of irrigation waters (micromhos/ cm.) 100 ............. 250 . ............ 750 ............. 4 mmhos/ CM.

It is apparent that the water - transmission and drainage properties of the soil and the salt tolerance of the crop to be groom are important factors in appraising irrigation waters from the standpoint of total salt concentration." A complete analyses of a sample taken 5/24/67 (copy attached) from an estimated 4.0 cfs flow at the samp3ing location also has the "same undesirable characteristics together with an excessively high sulfate content. The practice of pumping this drainage water with the treated effluent appears to have a conflict with water conservation and water pollution regulatory activities. The Irvine Ranch Water District Board of Directors have passed Resolution No. 1966 -5 which states: 118. Quality of Sewage No person shall discharge or cause to be discharged any of the following described waters or wastes to any District sewer: (K) Any brine waste from a home regenerated water softener unit. Installation of such home regenerated water softener units in the District will not be allowed unless the applicant demonstrates brine discharge facilities other than District sewers." Provisions within Permit No. 140 indirectly preclude the dis- charge of water softener wastes into the sewaging facility. Also sampling frequency of the effluent from the treatment plant is on the first working day of January, April, July and October with additional sampling as may be requested by the Director. It appears Irvine Ranch Water District could legally pump San Diego Creek drainage water together with their treated effluent to Sand Canyon Reservoir. The exceptions to this pumping being on sampling days as set forth in Permit No. 140 or a Regional Water Quality Control Board Resolution, when issued. By allowing the pumping of this drainage water by the subject; this may have adverse reactions from Regional Water Quality Control Board No. 8, operators of sewage treatment facilities in the Irvine Basin who do not have ocean outfalls but who do have stringent waste discharge requirements and other agencies interested in water quality management. -3- Also by allowing the practice of pumping and use of San Diego Creek drainage water, this dilutes the enforcement provisions of the County Industrial Waste Ordinance. If their allowable incre- mental increase on certain constituents is exceeded as determined from prescribed sampling provisions and legal action was taken because the discharger was in violation of his discharge requirements, then this places the enforcement agency in a very weak position be- cause the diverted drainage water is of much poorer quality than their treated effluent. A Department of Water Resources investigation of potential effects of water softener brine discharges on ground water quality within Southeastern Orange County for Regional Water Quality Con- trol Board #8 states that storage in the portion of East Coastal Plain Hydrologic Subarea, which I ante pret to the Irvine Basin, is.674,000 acre -feet of water. No The averaged flow as presented earlier of 6.6 cfs will return 4,745 acre -feet per year to the Irvine Basin which would appear to it have little degrading effects due to the tremendous dilution capacity available within the Basin. Therefore this diversion practice appears to have a possible conflict with regulatory agency policy and regulations. Orange County Flood Control District Permit No. 1216, issued to Tony Ormonde Jr., is for the removal of runoff waters for irri- gation purposes from Santa Ana - Santa Fe Channel near the confluence of Peters Canyon Channel. 6'1 qS ONf�i The diverted drainage waters are used for irrigation of alfalfa upon land leased from the U. S. Government. The quality of water at or above this point of diversion is as follows: Est. Date Flow E.C. pH Ca n Ng C 0 1 HLOa C1 Sa NO3 TDS 3/22/65 1 cfs 3500 - 210 123 333 0 207 317 1090 - 2450 5/20/65 - 2330 8.1 - - - - - - - - - 7/15/65 2.0 2400 - 153 70 - - 241 200 - - 1680 6/02/66 - 2480 7.7 170 74 - - 260 224 - 32 1736 Alfalfa (California common) has a medium tolerance to salt before a decrease in yield is expected from the accumulation of salts within the root zone. This irrigated land is located in the Anaheim Basin Pressure Area'so the resulting leachates are expected to drain into the flood control channels rather than into the usable acquifers of the basin. -4- The Orange County Department of Agriculture was concerned about the constituents in this water for irrigation of the alfalfa. Their concern was the use of DDT on specific crops which will have drainage waters tributary to the point of now Ormonde's diversion. No DDT was found in the drainage waters sampled. The USDA has a zero tolerance for DDT on alfalfa that is fed to milk cows, because of the DDT accum- ulative characteristics. Ground waters obtained from pumping wells within the Irvine Basin and the fringe of Anaheim Basin Pressure Area were analyzed for DDT in 1966 for which none were detected in the range of reportability of 0.00 parts per billion. These wells both contained nitrate levels of 43 and 22 ppm respectively (indicating an irrigated agriculture's influence) and were located within areas of known DDT applications. DISCUSSION AND RECOMMENDATION A letter should be sent to the subject requesting a clarification on this practice together with analyses of San Diego Creek Drainage water. Use of this drainage water on the contiguous golf course and other green belt areas that are located within the pressure area may be more desirable rather than diversion to a forebay area. It is suggested that letters be sent to interested agencies requesting their comments on the diversion of San Diego Creek Drain- age Waters as planned by the Irvine Ranch Water District after re- ceiving Irvine Ranch Water District clarification on the practice. The State Water Pollution Control Board received Attorney Gen- eral's opinion No. 55 -236 - March 30, 1956, wherein the question was asked? "Does drainage, flow or seepage from inactive, abandoned or com- pleted operations into waters of the State of harmful concentrations of the materials listed below constitute a discharge of waste over which a regional water pollution control board has jurisdiction: d. Return irrigation or drainage water from agriculture operations con- taining materials not present prior to use?" "Our conclusions may be summarized as follows: 1. The current drainage, flow, or seepage from inactive, abandoned or completed operations into the waters of the State of harmful concen- trations of all the listed materials constitutes the discharge of waste over which a regional water pollution control board has jurisdiction, if the discharge results in a pollution or a nuisance." 2. Waste discharge requirements prescribed by a regional water pollution control board to correct the pollution or nuisance which may result from such drainage, flow, or seepage should be imposed upon the persons who presently have legal control over the property from which the harmful material arises." S It is suggested a formal opinion be rendered from County Counsel pertaining to the responsibility of dry season flows in San Diego Creek for the following conditions. 1. Diversion from this pressure area by other parties to a ground water basin, within a forebay area, where in irrigated usage or ground water recharge of the water may result in a pollution of the superior ground waters of the basin. 2. The continued discharge of these waters to Upper Newport Bay by the Orange County Flood Control District where a nuisance may be created by the eutrophication of the receiving waters. a JUfl 16 1567 To: Mr. Osborne From: Jim Roberts Subject: Irvine Ranch Water District - Permit No. 140 Manager Bill Eppinger stated in a recent conversation that plans are to pump surface flows from San Diego Creek together with effluent from their treatment plant to Sand Canyon Reservoir.

Cl N0-1 TDS 7.2 mgpd 3858 511 42.7 2698 This hypothetical water is undesirable for irrigation purposes because of the high chloride and total dissolved solids concentrations. There will be a certain dilution factor when this hypothetical water is discharged to Sand Canyon Reservoir which will contain storm runoff of an unknown quality and variable quantity. This combined water is not expected to be used for ground water recharge practices in any significant amounts, but rather for irriga- tion purposes on selected crops. The leaching factor for use of these waters to maintain a favorable salt balance within the root zone may be as high as 50 %. U.S.D.A. publication, "Diagnosis and Improvement of Saline and Alkali Soils" Page 72, Table 10 shows the following leaching requirements: TABLE 10. -- Leaching requirementl as related to the elec- trical conductivities of the irrigation and drainage waters Leaching requirement for the indicated maxi - Electrical mum values of the conductivity of the drain - conductivity age water at the bottom of the root zone of irrigation waters (micromhos/ cm.) 100 ............. 250 ............. 750 ............. 4 mmhos/ cm.

It is apparent that the water- transmission and drainage properties of the soil and the salt tolerance of the crop to be grown are important factors in appraising irrigation waters from the standpoint of total salt concentration." A complete analyses of a sample taken 5/24/67 (copy attached) from an estimated 4.0 cfs flow at the sampling location also has the same undesirable characteristics together with an excessively high sulfate content. The practice of pumping this drainage water with the treated effluent appears to have a conflict with water conservation and water pollution regulatory activities. The Irvine Ranch Water District Board of Directors have passed Resolution No. 1966 -5 which states: "8. Quality of Sewage No person shall discharge or cause to be discharged any of the following described waters or wastes to any District sewer: (K) Any brine waste from a home regenerated water softener unit. Installation of such home regenerated water softener units in the District will not be allowed unless the applicant demonstrates brine discharge facilities other than District sewers." Provisions within Permit No. 140 indirectly preclude the dis- charge of water softener wastes into the sewaging facility. Also sampling frequency of the effluent from the treatment plant is on the first working day of January, April, July and October with additional sampling as may be requested by the Director. It appears Irvine Ranch Water District could legally pump San Diego Creek drainage water together,with their treated effluent to Sand Canyon Reservoir. The exceptions to this pumping being on sampling days as set forth in Permit No. 140 or a Regional Water Quality Control Board Resolution, when issued. By allowing the pumping of this drainage water by the subject; this may have adverse reactions from Regional Water Quality Control Board No. 8, operators of sewage treatment facilities in the Irvine Basin who do not have ocean outfalls but who do have stringent waste discharge requirements and other agencies interested in water quality management. -3- Also by allowing the practice of pumping and use of San Diego Creek drainage water, this dilutes the enforcement provisions of the County Industrial Waste Ordinance. If their allowable incre- mental increase on certain constituents is exceeded as determined from prescribed sampling provisions and legal action was taken because the discharger was in violation of his discharge requirements, then this places the enforcement agency in a very weak position be- cause the diverted drainage water is of much poorer quality than their treated effluent. A Department of Water Resources investigation of potential effects of water softener brine discharges on ground water quality within Southeastern Orange County for Regional Water Quality Con- trol Board #8 states that storage in the portion of East Coastal Plain Hydrologic Subarea, which I interpret to the Irvine Basin, is 674,000 acre -feet of water. The averaged flow as presented earlier of 6.6 cfs will return 4,745 acre -feet per year to the Irvine Basin which would appear to have little degrading effects due to the tremendous dilution capacity available within the Basin. Therefore this diversion practice appears to have a possible conflict with regulatory agency policy and regulations. Orange County Flood Control District Permit No. 1216, issued to Tony Ormonde Jr., is for the removal of runoff waters for irri- gation purposes from Santa Ana - Santa Fe Channel near the confluence of Peters Canyon Channel. The diverted drainage waters are used for irrigation of alfalfa upon land leased from the U. S. Government. The quality of water at or above this point of diversion is as follows: Est. Date Flow E.C. pH Ca Mg Ng 20a HCO-A Cl Sa NOg TDS 3/22/65 1 cfs 3500 - 210 123 333 0 207 317 1090 - 2450 5/20/65 - 2330 8.1 - - - - - - - - - 7/15/65 2.0 2400 - 153 70 - - 241 200 - - 1680 6/02/66 - 2480 7.7 170 74 - - 260 224 - 32 1736 Alfalfa (California common) has a medium tolerance to salt before a decrease in yield is expected from the accumulation of salts within the root zone. This irrigated land is located in the Anaheim Basin Pressure Area so the resulting leachates are expected to drain into the flood control channels rather than into the usable acquifers of the basin. -4- The Orange County Department of Agriculture was concerned about the constituents in this water for irrigation of the alfalfa. Their concern was the use of DDT on specific crops which will have drainage waters tributary to the point of now Ormonde's diversion. No DDT was found in the drainage waters sampled. The USDA has a zero tolerance for DDT on alfalfa that is fed to milk cows, because of the DDT accum- ulative characteristics. Ground waters obtained from pumping wells within the Irvine Basin and the fringe of Anaheim Basin Pressure Area were analyzed for DDT in 1966 for which none were detected in the range of reportability of 0.00 parts per billion. These wells both contained nitrate levels of 43 and 22 ppm respectively (indicating an irrigated agriculture's influence) and were located within areas of known DDT applications. DISCUSSION AND RECOMMENDA A letter should be sent to the subject requesting a clarification on this practice together with analyses of San Diego Creek Drainage water. Use of this drainage water on the contiguous golf course and other green belt areas that are located within the pressure area may be more desirable rather than diversion to a forebay area. It is suggested that letters be sent to interested agencies requesting their comments on the diversion of San Diego Creek Drain- age Waters as planned by the Irvine Ranch Water District after re- ceiving Irvine Ranch Water District clarification on the practice. The State Water Pollution Control Board received Attorney Gen- eral's opinion No. 55 -236 - March 30, 1956, wherein the question was asked? "Does drainage, flow or seepage from inactive, abandoned or com- pleted operations into waters of the State of harmful concentrations of the materials listed below constitute a discharge of waste over which a regional water pollution control board has jurisdiction: d. Return irrigation or drainage water from agriculture operations con- taining materials not present prior to use ?" "Our conclusions may be summarized as follows: 1. The current drainage, flow, or seepage from inactive, abandoned or completed operations into the waters of the State of harmful concen- trations of all the listed materials constitutes the discharge of waste over which a regional water pollution control board has jurisdiction, if the discharge results in a pollution or a nuisance." 2. Waste discharge requirements prescribed by a regional water pollution control board to correct the pollution or nuisance which may result from such drainage, flow, or seepage should be imposed upon the persons who presently have legal control over the property from which the harmful material arises." C It is suggested a formal opinion be rendered from County Counsel pertaining to the responsibility of dry season flows in San Diego Creek for the following conditions. 1. Diversion from this pressure area by other parties to a ground water basin, within a forebay area, where LIn irrigated usage .or ground water recharge of the water may result in a pollution of the superior ground waters of the basin. 2. The continued discharge of these waters to Upper Newport Bay by the Orange County Flood Control District where a nuisance may be created by the eutrophication of the receiving waters.

Osborne, Director Water Pollution Department Subject: Irvine Ranch Water District, Industrial Waste near Irvine (File No. MS61.00) Gentlemen: Reference is made to your letter concerning the proposed waste dis- charge from the Irvine Ranch Water District treatment facilities and also to the meeting held in your office on February 17, 1966, which was attended by a representative of our Water Quality Section. The following comments are offered. The discharger proposes to treat domestic and industrial waste waters from the University of California at Irvine. Water supply for the University is obtained from The Metropolitan Water District of Southern California. The initial capacity of the treatment facilities will be 2.0 million gallons per day. Effluent from the activated sludge treatment plant will be pumped to Sand Canyon Reservoir for storage. The treated effluent Will then be used for irrigation on a golf course, agricultural land, greenbelt and park areas, and a jungleland in Sections 8 through 11, 14 through 17, 22, 23, and 26 of T6S, R9W, s3am. These areas are located on both Water - bearing and nonwater- bearing sediments in East Coastal Plain Hydrologic Subarea. In fall 1963 ground water movement in the disposal areas located on water- bearing sediments was generally northeast towards a pumping depression in the vicinity of Section 34, T59, R9W- Waste waters not consumptively used by evapotranspiration through the irrigation use will percolate.and commingle with the ground waters. The depth to ground water, as measured at three wells in the area during fall 1963, generally varied from 20 feet to 70 feet below ground surface. The Department has no analyses of samples from wells located within the proposed.disposal. areas. However, analyses of samples obtained in 1964 -65 from wells 6S/9W -2A4 and _2D1, which are located about 1-2/2 miles northeast of the disposal areas, indicate that the ground waters generea -ly meet all the ieCE1VED FEB 2 8 1966 011HVUE WUNTY \ FLOOD CONTROI hlM County of Orange -2- February 24, 3.966 recommended limits of the United States Public Health Service Drinking Water Standards except:that for total dissolved solids (TDS). Concentrations of TDS in the samples ranged from 499 ppm to 1,037 ppm. Generally, the waters are Class 2 for irrigation uses because electrical conductance values exceed 1,000 micromhos per centimeter. , The receiving ground waters in the vicinity of the disposal areas are used for domestic and irrigation purposes. Other downstream ground waters are used for domestic, irrigation, and also for industrial uses. Waters of San Diego .Creek,' which.traverses the disposal area, flow into Upper Newport Bay where they are used for recreational and industrial purposes. In order to preserve the quality of the receiving waters for the pre- vailing beneficial uses, the Department recommends that the requirements of the industrial waste permit issued by your department be based on the quality of the water supply plus reasonable increments. We suggest that these requirements stipulate that the discharge contain no radioactive wastes and no toxic or deleterious substances in quantities that would render the receiving waters unsuitable for beneficial uses. To ensure compliance with the requirements, we recommend that the discharger be required to conduct a monitoring program. We suggest that this program include bimonthly collection and analysis of-effluent samples. Complete chemical and heavy metal analyses should be made of-these samples and copies of the reports should be sent to your department. Sincerely yours, James J.

Anderson, Executive Officer SANTA ANA REGION oentlemenl The following is in addition to and further explanation of a reclaimed water discharge, as explained to Mr. Paine of your staff, on May 15, 197" at the Rattlesnake pumping and treatment complex, Irvine Ranch Water District. At 0830, May 15, 1978, District Operations personnel rerouted the plant discharge from the Sand Canyon to the Rattlesnake lend outfall. For your reference, effluent from the Michelson Reclamation facility is pumped to a diversion structure at the base of Rattlesnake Dam. Plant flown in excess of irrigation demands flow from the structure to the weL well of the Rattlesnake pump station and are lifted into the reservoir. The Rattlesnake pump station operates "on demand" with a high well level alarm transmitted to the Michelson Reclamation facility in case of pump failure. At 1030, same date, District personnel from the Engineering Section noti- fied Operations staff that the Rattlesnake pump station alarm was operating and that water was escaping from the station. No alarm had been received at the Michelson facility. The treatment facility flow was immediately by- passed to storage. Maintenance personnel reported that the pump station had failed to start and that the alarm system was functional and should have notified operations staff of the impending problem. A test of the alarm system at the complex revealed the line voltages on the telephone company telemetry wiring were unexplainably low, hence, in- sufficient power to transmit the signal the distance to the Michelson facility. 17 . 111714 i :€H Mr. Jem(A,t W. An, lcr unit Approximately 0.0 million gallons escaped the station wet well. A portion flowed overland approximately .2 miles and entered flicks Canyon Wash. This subsequently flowed approximately .5 miles down the Wash, then terminating and porcolating into the dry stream channel. Pertinent water quality data on the discharge water is listed below. 5 -14 -78 Constituent Value Suspended solids (mg /1) 2.0 (C) Turbidity (NTu) 0.8 (c) Coliform (MP14/100 ML) L1 (g) Chlorine residual (mg /1) 16.5 (g) Settleable su?ids (ml /1) 40.1 (g) 5 -15 -78 Suspendal solids (mg /1) 1.4 (c) 'turbidity (M) 0.7 (c) Coliform (MPN /100 ML) 42 (g) Chlorine residual (mg /1) 11.9 (q) Settleable solids (ml /1) 40.1 (g) (c) - composite sample (g) - grab sample Sn recap, the failure of Rattlesnake pump station to function properly should not have been, in itself, a condition which made a disoharge inevitable. The failure to properly transmit and receive the well level alarm caused the conL:!tion. District staff met with telephone company personnel, same date, to locate and mitigate the problem. The telephone cable pair used for the alarm transmission were found to be deteriorated, i.e. the cable was shorted, making it impossible for the signal to penetrate to the alarm panel. This pair was disconnected and an undamaged set placed into service. The alarm circuit check is scheduled during regular station maintenance periods. The last alarm chock was made on March 29. Because of the recent problem and uncertainties within the wiring system, the alarm check frequency has been increased to bi- monthly. We regret the circumstances which led to subject discharge and feel oonfi- dent that measures taken to prevent a similar situation will be successful.

Semple, dated April 13, concerning the above subject. You will note that we have taken into account all areas of storage available to us. This report reveals that the beat over -all direction for us to take is the additional release of 250 AF from our Sand Canyon Reservoir. This amounts to 6.25 days at the maximum capacity of our facility. we have been advised by our weather consultant, namely the National Weather Institute, that additional rains amounting to 1 inch or more during the last weak of April are anticipated. This would cause runoff into the reservoir, therefore, it may be wise to consider a 10 day release or 400 AF to accommo- date the runoff. The additional days would be utilized only in the event that we do indeed experience the forecasted rainfall. It seems practical to consider the runoff potential now and provide the flnxibility to accommodate this anticipated problem. Your consideration of this matter will be greatly appreciated.

"I Reclaimed Water Storage Status j i ' ! •i April 13, 1978 FILES 8.5 We have reviewed the statue of the District's irrigation storage avail- ability in Sand Canyon, Rattlesnake Reservoirs, and the duck ponds. As of 4- 13 -78, the storage available is 319 AF. This represents a total of 21 days storage based upon the Michelson plant flow of 15.3 AF per day. The detail of these figures is as followst Sand Canyon Reservoir Rattlesnake Reservoir Duck Ponds TOTAL Available Storage AF Daye 136 8.9 53 3.5 130 8.5 319 20.9 A3 you mentioned to me earlier this week, The Irvine Company, who is our major consumer of irrigation water, does not plan to take any appreciable amount •`. water until approximately May 15, 1978. Coupling this fact with an asau:. -A 1" rainfall between now and May 15, 1978 a total of 570 AF (490 AF of plant production and 80 AF of rein runoff into storage) storage will be required. Based upon the facts state6 above, an excess of 250 AF of storage or discharge is required. There are three alternatives which can be taken. They are as followst Alternative I Raise the Send Canyon Reservoir spillway three feet by placing send bags and permit the water surface elnvation in Rattlesnake Reservoir to rise to spill elevation 412 feet. The placement of send begs would increase the storage capacity by 170 AF and raising the allowable water surface elevation at Rattlesnake Reservoir to the spillway would increase the amount of avail- able storage an additional 190 AF, thereby increasing the total amount of storage by 350 AF. Alternative II Allow the 250 AF excess to flow over the Send Canyon Reservoir spillway. Alternative III Initiate controlled discharge from the emergency outlet at the bass of Sand Canyon Reservoir dam. �� w. 11. .�,•ml�lr .�.j A]'ri1 IN We reviewed Alternative I with the IPWD Gams and reneivoirs consultant, W. A. Wahler and Associates. They :fated that raising the allowable water surface elevation in Rattlesnake Rnso"oir to its maximum capacity of elevation 412 feet would not be recommended duo to the uncertainties of the safety of the dam with a full reservoir under a dynamic ntreas condition (earthquakes). Since they could not recommend raising the water surface elevation at Rattlesnake, this would mean that the placement of a sand bag berm in the Sand Canyon Reservoir spillway would be insufficient to accommo- date the entire amount of excess irrigation water and spillage over the berm may cause it to fail, thereby presenting a potential downstream safety hazard. Based upon W. A. Wahler's recommendation, we recommend that this alternative be eliminated from further consideration. Alternative II is a viable method of releasing the excess water as statsd hereinl however, in vitw of the substantial &mount of damage which occurred as a result of the flov over the spillway (approximately $140,000 worth of damage) during the storm and its potential for added damage if additional flows over the spillway occur, this solution should be avoided if possible. It should also be noted that we have. completed the repairs to the E1 Toro line at Sand Canyon Reservoir at an estimated cost of $12,000. If additional flows over the spill- way occur, this line will suffer some damage and will possibly need additional repair. In view of the safety hazards inherent with Alternative I and the added addi- tional repairs which may be needed if Alternative II were implemented, it would only seem practical to adopt Alternative III, namely initiate controlled dis- .;harge from the 24" emergency outlet at the base of Sand Canyon Reservoir. By doing so no significant additional damage will occur to District and other related facilities. Based upon the figures stated above it is recommended that 250 AF be released from the 24" emergency outlet. Our records indicate that the capacity of the outlet is 40 Ar per day. Therefore, the outlet must be activated for 5.25 days to accomplish this purpose. PRtCWBtwht cc: C. W. Bailard Hr. Joe Kulikowski, W. A. Wahler t Assoc.

Total estimated discharge from 2 -10 -78 to 2 -16 -78 was 300 AF, 250 AF from sand Canyon and 50 AF from Rattlesnake. 3 -1 -78 a) Sand Canyon Reservoir began to flow over the spillway (at 4130 AN) al an estimated flow of 150 cfs. It should be noted that this flow was an estimate based upon the height of water flawing in the spillway, the estimated water velocity, and U,e width of the spillway. It was further justified by flow measurements observed by UCI. b) significant damage to IRWD facilities below the sand Canyon spillway began to occur. This emergency condition was reported to regulatory agencies and a controlled discharge from the 24" emergency outlet located at the base of Sand Canyon Reservoir was reactivated at 1130 AN to minimize damage to downstream facilities. Estimated flow from the outlet was 35 cfe. c) Began controlled discharge from Rattlesnake Reservoir (at Hick@ Canyon Wash) via the Jeffrey line at approximately 3000 gpm. 4 J I {d�.r,F !� 6B!CSYi Page 2 W.

Anderson, Executive Officer Regional Water Quality control Board 6833 Indiana Avenue, Suite 1 Riverside, G 92506 Dear Mr. Andersont This letter in being written to detail the sequence of events which were discussed by telephone on January 17, 1976 between Mt. William Sample end your office relative to Irvine Ranch Water District's reservoirs and the impact of recent rains on our irrigation facilities, The District reclaimed water reservoir operations are geared to maximise winter storage capabilities. We have considered November 1 through April 30 as the season having the highest probability of rain. On November 1, 1977, Sand Canyon and Rattlesnake Pemervoirs were at the fallowing minimum operating levelst Sand Canyon 283 AP in storage (30 %) 950 AF capacity Rattlesnake 159 AP in storage (11%) 1450 AF capacity Totals 442 AF in storage (18%) 2400 AF capacity Water in storage increased nominally through January 4, 1978. Attached are copies of daily status reports showing relative levels and storage in both Rattlesnake. and Sand Canyon Reservoirs. Due to the w4slnout of Culver Drive near Main Street, we elected to temporarily shut down the reclaimed water transmission line to Rattlesnake from January 4 to January 30. During this period we transmitted to Sand Canyon, however, the total volume from the plant was quite small in relation to the volume of runoff water. In summary, the major reason that sand canyon is now at 75% of its total capacity is primarily due to runoff. Presently we are utilising all of our existing facilities to attempt to relieve Sand canyon. our present operating mode is as follow t a) Plant production is being transmitted to Rattlesnake. b) Jeffrey system (2500 gpm) is moving water from Sand Canyon to Rattlesnake. c) Duck ponds.are taking 500 gpm directly from Sand Canyon. in view of impending additional runoff and possibility of losing transmission capacity in our Rattlesnake and Jeffrey lines due to washouts, we feel that It is imperative that we develop a contirgency plan to relieve Send canyon heservoir if it becomes absolutely nucuss&ry. Sand Canyon at present has 3 feet of sandbags across the spillway. Our calculations do not take this additional capacity in account due to lack of total reliability. In the event of additional rain causing substantial runoff or in the event of loss of transmission capability to Rattlesnake; two options are availablei 1) controlled discharge through valy" at the base of Sand Canyon dam, 2) uncontrolled discharge over the.spillway. After careful consideration we feel that optiois 2) has the risk of con- siderable property damage including potential damage to the irrigation transmission facilities downstream of the spillway. Option 1) has limited capacity in terms of available hardware to discharge significant volumos. we are geared to exercise option 1) if, in our opinion, this becomes absolutely necessary. We propose to monitor water quality as it leaves the reservoir and make relative comparisons of the impact on downstream flown. In addition, the 208 study has been monitoring runoff water quality going into both reservoirs and this information is available to all concerned. I hope that this brief description of our present situation will provide you with enough insight into our present position. Should you have any further questions or suggestions please give me a call.

Current Reservoir Storage Statue Report. Historically speaking, on February 7 we presented to a member of your staff a status report which revealed that we had 47 total days of storage available in all our reservoirs. (Days of storage are calculated on the basis of 1.5.3 AF of plant production per day and assumes no usage and no runoff.) This position when related to the theoretical end of the rainy season and start of the irrigation season was a relatively comfortable position. On February 9 we had 42 days of storage available. The reduction of 5 days was created by plant production and runoff. On the night of February 9 we experienced a storm which spanned approximately 4 hours and was rated at 1.8 inches of rainfall. The net effect of this storm cost us 24 days of storage. The following day residue runoff and plant production cost us an additional 2 days of storage. At this point in time Send Canyon Reservoir had 80 acre feet of storage remaining. If we experienced another storm of Paq.r 2 F,hrual� 211, 1778 Mr. James W. Anderson the magnitude or even near magnitude of the Fubruary 9 storm a very significant spill would occur. We and our consultants were extremely concerned from the standpoint of safety, damage to land and downstream facilities. In addition District facilities located in the general area of Sand Canyon could be adversely affected by a significant "pill. Those facilities included a road, security fence and two transmission mains. One transmission line supports the E1 Toro Marine Corp Air Station, the other line went to Rattlesnake and provided a relief from Sand Canyon Reservoir of 7.5 AF daily. (See chart attached.) The effect of runoff, as shown on the charts provided, is significantly worse at Sand Canyon than at Rattlesnake. This was one of the considerations in operating in the mode of transmitting all plant production to Rattlesnake Reservoir and relieving Sand Canyon to the maximum of our capability to do so. On February 10 we discussed our situation with members of your organization, advising them that in this emergency we felt we should proceed with a con- trolled release from Sand Canyon Reservoir. The capability of our facilities to release was 50 AF in 24 hours. Through thin emergency procedure we were able to relieve the situation to the degree that we ineroaned our flood control storage by that volume. Concurrent with the release we instituted a quality control program which provided adequate tests at the point of dis- charge and 't.rther downstream. Results of these testa are provided under separate cover. It is important to note that the tests showed that the TDS of thL water in Sand Canyon was only 704 - 440 mg /1 which prove that the water In Sand Canyon Reservoir in almost entirely natural runoff. On Sunday, February 12, we experienced another storm during a short time - frame that was rated at 1.7 inches. The net result of this atom reduced our total days storage to 10 days equally split between the two reservoirs. We continued our emergency procedures until Wednesday, February 15 at which time we had enhanced our storage position at Sand Canyon but decreased our storage available in Rattlesnake. The overall net days available on February 17 had been increased from 10 days to 16 days and at this point we discontinued our emergency operations. Total plant production between now and the end of the rainy season March 31 is 637 AF or a requirement of 42 days of storage va an availability of 17 days for a net difference of 25 days if no reclaimed water is used. As previously mentioned, our records show conclusively that we have on one occasion picked up a total of 375 AF (275 at Sand Canyon and 100 at Rattlesnake) during one storm and 150 AF during the February 12 storm as well an total runoff of about 900 AF by mid - February compared to a historical estimated average annual runoff of about. 400 AF. This is combined with very low irrigation demand be- cause of the abnormally high rainfall to make the management of out reservoirs a special situation. We have available to us expert weather forecast infor- mation which tolls us the followings Normal average rainfall for March in 1.75 to 2 inches. This March we will receive at least 1 to 2 inches above normal. The bulk of this rain will be between March 1 and 4 and between the 14th and 18th. The specific runoff will be dependent upon soil conditions, intensity and duration of the atom. if the weather predictions are correct we could have of poq,• ] rohruary 2H, 1'1'111 Mr. .lumen W. Andursion conditions that woul:l indeed produce very significant runoff. our consultant who is in charge of our data surveillance program has advised us that the safety of Rattlesnake Dam may be effected by sustained high reservoir levels and suggested that we lower the reservoir level to 409 feet until studios can be completed. Their recommendation is based on the facts that this is the first time the reservoir level has been as high as 411 ft. (compared to the spillway elevation of 412 ft.) and they observed increases in piezometer levels which were higher than they had anticipated. We feel that we ahould apprise you of the fact that under any not of normal conditions the District provided adequate storage facilities. The magnitude of the storms within a short time -frame created theme adverse conditions and will cause Sand Canyon to begin to spill over during this week when the next storm occurs. At the same time, IRWD is continuing with its studies of water quality and runoff as part of the Zoe progr.rn. The.. studies which are planned for e duration of at least two years, have so far not shown any significant differ- ence between reclaimod and runoff water quality when considering the hydro- dynamic behavior of the upper Newport Bey. In order to assure the future usefulness of its dams, IRWD will also accelerate its review of the Rattlesnake Dam stability and will conduct a study t� deter- mine the cost of spillway improvements for Send Canyon Reservoir. The IRWO has also completed the three NPLCS applications for the experimental Stream Augmentation Program and the EIR docom,�nts requested by the Santa Ana Regional Water Quality Control Board have been routinely scheduled for IRND Board consideration on 27 February. The completi. applications will then be forwarded to your office for consideration to permit short term monitored releasaa of reclaimed water during wet and dry periods during the next two years an pert of an experimental program. We deeply appreciate the excellent cooperAtion provided by your staff during this recent emergency period. Your favorable consideration of our circumstances and our desire to protect our facilities will be greatly appreciated.

This memo covers three basic areas, namely, pertinent facts, operational mode during controlled discharge and discharge requirements to avoid further spills from our reservoir and relieve Rattlesnake Reservoir to 409 elevation. We would appreciate your review of this information and advise if it suffices as a report to you of our conditions and ongoing relief required to avoid further spills from our reservoir. In addition to this report, we wish to advise that the District is con- tinuing its quality monitoring program as previously discussed. Also the 208 study is vs, y active in the area of quality measurements including measurements in Newport Bay. The only significant damage to facilities during the short time that Sand Canyon Reservoir discharged over the spillway involved the fact that we lost the reclaimed water transmission line going to E1 Toro Marine Corp Base.

As of 8 AM on 3 -2 -77 a total of 10 AF has been released from this outlet during this period. 4. As of 3 -2 -78, at 8 AM a total of 35 AF (12,000 %a) has been released from Rattlesnake Reservoir and a total of 26 AF 17650 %a) has been released from Sand Canyon via the above connections during this report- ing period. 5. Operational mode during controlled discharges A. Plant flow to Rattlesnake Reservoir via the Rattlesnake pipeline. B. The Jeffrey line system has been isolated from the Rattlesnake pipe- line in order to provide plant water to the Walnut line and Woodbridge landscape irrigators (water from the Jeffrey line system to the above- mentioned landscape irrigators has been valved off since unscreened water is currently flowing in the Jeffrey line.) The two pipelines have also been isolated from each other in order to Saxi- miss the flow being released from Rattlesnake Reservoir by bypassing the strainer. W. M. Scm)il e March 2, l ?78 IM 6.

S. Environmental Protection Agency (EPA) has promulgated regulations requiring publicly -owned treatment works (POTWs) with a design flow greater than five million gallons per day to " develop and implement local pretreatment programs according to a compliance time schedule.. Those regulations also apply to POTWs with smaller design flows which receive industrial waste of a volume er nature that should be regulated to prevent interference with treatment processes, or to prevent the discharge'of pollutants which would pass through the treatmen: system unmodified. 3. EPA is the control authority under Federal regulations responsible for overseeing local pretreatmeit programs. EPA and public interest groups have been urging the.State to assume this function, and the Legislature, with passage of Assembly Bill No. 3667, has directed the State Board to initiate a program to satisfy Federal pretreatr.*nt'regrirements and to seek delegation of the Pretreat- ment program. However, EPA will remain the primary enforcement agency until authority is delegated and adequate resources are provided to the Regional Board for full implementation of the pretreatment program. 4. The dischargers listed-in Finding 1 have EPA - approved pretreatment programs. 5. EPA has requested that provisions be incorporated into the above dischargers' NPDES permits requiring full implementation and enforce- ment of approved local pretreatment programs and submittal, of annual reports in accordance with Federal pretreatment regulations and guidance documents. f•%':`, �i'',:�•.,�.,1•'- �fflP' 4..

CA 927,.1 This is to confirm my conversation with your office on November 4, 1986, regarding the need for Irvine Ranch Water District to begin a controlled emergency discharge of reclaimed water from Sand Canyon Reservoir. We have begun such discharge at 8:00 AM on November 5, 1986. Flow rates will vary up to 35 cfs. Reporting of flow rates and water quality information will be provided with the monthly Michelson Reclamation Plant operational report, as required by existing permits. Several steps were taken to avoid emergency discharge including reducing .F reclaimed water rates to several large consumers; obtaining special permission to allow IRWD to exceed current maximum allowable storage in Rattlesnake Reservoir and construction of temporary treatment and new service connection's facilities from Rattlesnake Reservoir to permit expanded use of reclaimed water. These measures extended the time before emergency discharge was required; however, since current storage at Rattlesnake is near capacity and Sand C ?nyon Reservoir water in storage is well into the 250 acre -foot freeboard limit, discharge has begun. Such discharges will continue until sewer flow tie -in facilities are completed with Orange County Sanitation District. These facilities will be completed by January 1987. However, it should be noted that storm flows into Sand Canyon Reservoir may require subsequent emergency discharges in the future. Sincerely, IRVINE RANCH WATER DISTRICT (L- �j . L� Carl W.

Chang of this office on August 15, 1985. It was noted at the time of inspection that the effluent sampling equipment was.not refrigerated. In accordance with the standard methods and NPDES permit conditions,all samples should be properly collected and preserved. All samples during collection and prior to analysis must be refrigerated and maintained at a constant temperature of 40 C. A thermometer is also needed to be installed to record the temperature of the sampling equip- ment during the sampling period. Our records show that you have been continuously violating the average allowable limits contained in your waste discharge requirements Order No. 76 -049 for total filtrable residue, sulfate, and Na+ + 112 TH at least for the last two years. We are very concerned that unless immediate corrective actions are implemented, violations of your discharge permit limitations will continue. You are requested to'subnit a report by October 10, 1985, that addresses our concerns in this letter as well as your proposed plans to achieve consistent compliance with effluent permit limitations.

The discharge is necessary to complete maintenance procedures on the Sand Canyon Dam outlet structure. All reclaimed water was previously drained to the distribution system or the Michelson Water Reclamation Plant. You indicated that this discharge would be permitted with the following stipulations: 1. The rate of discharge will be adjusted to minimize, as much as possible, the discharge of silt and other solid material to Sand Canyon Wash. 2. A small settling basin will be constructed to further minimize the transport of silt. We inspected this settling basin during your visit of November 14, 1984. 3. Daily grab samples of the discharged water would be collected and analyzed for suspended solids, BCD and coliform organisms. These data would then be forwarded to you for use in background information. No other monitoring requirements were imposed.

Re: Emergency Discharge Monitoring and Reporting Program Dear Mr. Mijares: We have received your recent letter of January 9, 1987 to Carl Ballard, IRWD (See attached), outlining a monitoring and reporting program for the Irvine Ranch Water District's Emergency Discharge from Sand Canyon Reservoir. After discussing this matter with Mr. Ballard, we have determined that his recollection of a telephone conversation with you resulted in the understanding that the only change in discharge monitoring would be an increase in the frequency of sampling from monthly to weekly. However, in reviewing your letter (item 3) we noticed that you have requested additional constituents to be analyzed including total phosphate, oil and grease, surfactants, total dissolved solids, mercury, arsenic and selenium. These constituents were not included in the original monitoring program No. 81 -114. We have already implemented the weekly monitoring program with the exception of the additional constituent monitoring. If you do not agree with what we are doing please contact me.

Young Director of Engineering and Planning Irvine Ranch Water District P. 0. Box D -I Irvine, CA 92716 -6025 RENEWAL OF THE EMERGENCY STREAM DISCHARGE PERMIT Dear Mr. Young: GEORGE DEUKMEJIAN, Governo We have reviewed your application for the above - referenced project. This matter was also discussed with you and your staff. However, additional information is required before we can proceed with the renewal of the permit. �s. nq First, please clarify the completion date of your project to connect the Michelson Plant to the County Sanitation Districts of Orange County ( CSDOC). We have been given two different dates from you and your staff. In a recent telephone conversa- tion, Mr. Keith Lewinger informed Mr. Li -Min Shih of my staff that the completion date will be March 1987; however, you recently told Mr. Hisam Baqai and Mr. James Bennett that the completion date will be October 1986. Second, the tern of "emergency" discharge must be defined. It appears that two separate definitions are necessary; one for the present (before the connection is complete) and another for the future (after the connection is complete). As you are aware, the State's Bays and Estuaries Policy of 1974 prohibits any new discharges of municipal wastewater to any bay or estuary unless it can be shown that such discharges will enhance the quality of the receiving waters. The justification of allowing "emergency" discharges, as stated in Finding 5 of Order No. 81 -114, was due to the limited amount of available storage at Rattlesnake Reservoir because of a structural problem and to prevent damage to downstream facilities caused by spillway overflows at Sand Canyon Reservoir which would be caused by stormwater runoff. In a recent telephone conversation with Mr. Shih, Mr. Lewinger stated that since the structural problem at Rattlesnake Reservoir had been corrected, IRWD has maintained two feet of freeboard in this reservoir and in the Sand Canyon Reservoir. - In the winter months, the minimum reclaimed water demand is around 4 -6 MGD. However, these two reservoirs have been kept essentially full to provide sufficient storage capacity to meet this demand. In order to prevent spillway overflows, IRWD has discharged reclaimed water whenever the stormwater runoff raises the water level in these reservoirs close to or over the set freeboard level. It appears that IRWD has not developed a management plan to restrict the number of discharges. Can the District maintain less water in the reservoirs and still have sufficient capacity to meet demands? If so, this may greatly reduce the number of discharges necessary. This information is needed to that we can determine if there is truly a need for a discharge permit and what constitutes an "emergency" discharge. This is especially valid, once connection to CSDOC is complete. Mr. Ronald E. Young, IRI4D -2- April 4, 1986 Third, the quantity of flow reported by IRWD is dramatically different from what was estimated by the Orange County Environmental Management Agency (OCEMA) and a concerned citizen. We would like to have your comments on the method of flow measurement used by your staff and on the validity of reported flows. You are also required to provide the information regarding the flow measurement device currently installed at each of the discharge points for our review. Please provide the requested information to this office by April 18, 1986. If you have any questions, please call me or Li -Min Shih of our Regulations Section. Sincerely, Gerard J. Thibeault Supervising Engineer LMS:pk LA li.. Study Finds Nitrates Are Influencing Bay By KRISTINA LINDGREN. Times Sraf) Wr grr An .estimated 12.000 pounds of nitrates flowing daily into the Up- per Newport Bay wildlife reserve have caused an explosive growth of plankton and algae that has given the water its murky brown color, according to a study by a Newport Beach physician. The main sources are fertilizer - laden- runoff from three Orange County wholesale nurseries, agri- culttic runoff from water- inten- sive -crops and reclaimed sewer water discharged by the Irvine Ranch Water District, Dr. John F. Skinner said. Nitrates in the bay water pose no threat to public health or to wild - life, biologists say. ,High concentrations of ,nitrates and phosphates have been blamed for the death of aquatic life in freshwater lakes and rivers. In a process known as eutrophication. the overstimulated plant and algae life eventually uses up all the oxygen needed by other organisms. Reduees Diversity The process is not considered deadly to saltwater bays and estu- aries because daily tidal flushing dilutes and washes away much of the chemicals. However, biologists say excessive levels of nitrates may reduce the diversity of marine life in Newport Bay, favoring filter - feeding fish like mullet and ancho- vies over the sport fish historically there: For Skinner, a water sport en- thusiast who has been active in bay pollution studies in recent years. excessive plant-growth makes even the lower bay an unpleasant place to swim or boat. "I think the most disconcerting thing to the public has been the dirty look of the water, but many residents have been bothered by nuisance growth of filamentous algae and sea lettuce around boat docks and boats:' Skinner said Wednesday. Skinner said water samples gathered during the month of Jan- uary from points along tributaries feeding into liewpmK Bay allowed high concentration of nitrate fer- tllizera'in runoff from three large wholesale nurseries. The three are the El Modeno Gardena. Hines Wholesale Nurser - lea and Bordier's Nursery, all of which operate in the foothills northeast of Irvine Thou"M s of Pounds The samples. tested in a county laboratory. indicated concentra- tions of nitrates averaging as high as 400 milllgrapme per liter of. water, and in some oases reaching much higher. Skinner said. Depending on the volume of water flowing into the bay's main tributary. Satz Diego Creek, the amount of nitrates flow- ing daily could average more than 3,000 pounds from each of the nurseries He said the practice of mixing nitrate -rich chemical fertilizers with water as the nursery plants are irrigated causes runoff of al- most 50% of the water and fertiliz- ers. Elsewhere in California, Skinner said, nurseries are being required to capture and reuse irrigation runoff, and he suggested in a recent meeting with representatives of the county. regional water quality officials .and the Irvine Co. that such practices be adopted in Or- ange County. Officials for the nurseries could not be reached for comment on their fertilizer practices. Bob Collacou. head of the county Environmental Management Agency's environmental services section, said Skinner's results gen- erally coincide with county studies of nitrate levels conducted over the last decade. "We have determined that the concentrations we are seeing are not associated with urban develop- ment. " Collacott said. Please see BAY, Page 10 Unravel ;ng a murky mystery Couple hunts source of bays ftcoloration By Tom Kroneriffo6w The Plagiste; NEWPORT BEA Jack Skinner had heard the question once too often: Why is Newport Bay such a murky shade of brown? Finally, the physician and his wife went upstream in search of an an- swer. Playing part-time sleuths in re- cent weeks, the water-quality ac- tivists — who have become the community's local experts on the bay — followed a trail of clues that started at the Upper Bay ecologi- cal preserve and meandered up the San Diego Creek and other tribu- taries. The trail ended for the most part in the foothills of Irvine, Nancy and MURKY FROM 81 ter, a conclusion backed up by county officials. Other lesser sources the Skinners name include the Irvine Ranch Water District and Irvine Co. agricultural lands. The couple's informal investiga- tion already has triggered plans for a meeting between the nurser. ies, the Skinners, environmental officials and the Irvine Co., which leases land to two of the nurseries. The topic will be a strategy for harnessing the source oflhe algae, which officials stress is not a health threat. "We don't see (the nurseries) as bad guys," Mrs. Skinner said. "We fully expect ev- eryone will cooperate." For years, the algae infestations have been tracked quietly by the county Environmental Manage- ment Agency and other water - quality boards, said Bob Collacott, director of environmental m sources for the agency. Yet the Skinners' work, accord- ing to several officials, is the first to single out El Modena Gardens, Hines Wholesale Nurseries and Bordier's Nursery publicly as the major causes, officials said. Jim W� A ft, - Jack Skinner gathers a water sample for anslyah from an Irvhro charwW. Jack Skinner disclosed this week. There they found three wholesale nurseries that drench their plants with liquid fertilizer, producing a nitrogen -rich spillover that eventu- ally washes into the bay. "Those of us in the environmen- tal community were aware ... of a significant problem," Collacott said. "Of course, it takes a Jack Skinner to make these things pub- lic." Officials from two of the nurser- ies did not respond this week to inquiries about their fertilizing practices. George Gutman, of Hines Wholesale Nurseries, said the company has violated no laws and already irrigates a fourth of its acreage with a "drip" method known for producing less runoff. Although the increasingly dense algae growths of the last decade are mostly an aesthetic nuisance, the doctor believes their brown pigment has tarnished enjoyment of the bay, as have the DDT, bacte- ria and other colorless health men- aces in the water. "The thing that bothers resi- dents the most is the appearance of the bay," said Skinner, an internist at Hoag Memorial Hospital Pres- byterian. "Everybody comes up to me and says, 'The bay looks so dark, I don't want to swim in it.' " The former lifeguard and water - sports enthusiast said he quit swimming in the harbor years ago. "When I'd look underwater, the visibility was so poor ... I couldn't see more than a couple feet," he said Armed with charts, snapshots and laboratory readings, the New- port Beach couple are blaming the nurseries for the lion's share of al- gae that sullies the once -clear wa- Please see MURKYAB13 i Confident that PrOfress was un- 'der way on other bay Pollution fronts, the Skinners decided near the end of 1985 to unravel the algae mystery. They dug up published studies that said nitrates, the main 5ngredient in fertilizers, were the key nutrient for marine algae. Skinner called the county and took down some raw data on ni- trate loads flowing down San Diego Creek. When he added and multi - J)lied the numbers together, he had a stunning sum. The calculations showed about 12,000 pounds of nitrates a day were flowing into the bay from San Diego Creek and its tributaries. "It's the equivalent of putting 600 20 -pound bags of fertilizer in the bay every day," Skinner said. "I was flabbergasted. I multiplied it 15 different ways, but it came out the same way. And it was a let." He and his wife then set out to explore the watershed. On week- ends, by car and on foot, the Skin- ners covered as much of the 200 - square -mile watershed as they could, they said. The Environmen- tal Management Agency contribut- ed the bottles the Skinners used in pulling three dozen water samples out of several channels and creeks. After gathering the samples on weekends, Mrs. Skinner drove to Anaheim on Mondays to bring the bottles to the agency's laboratory. she said. There the county mea- sured nitrate concentrations in the water. The biggest numbers were regis- tered by samples taken just down- stream of the three nurseries, ac- cording to a diagram Skinner com- piled. They average about 400 milligrams per liter. BY comparison, the average Sand Canyon Reservoir level is about 38 milligrams per liter, and runoff from the Big Canyon hous- ing development near the water's edge averaged 2.6 in previous tests by the county. Skinner figured each of the nurs- eries contributes 3.000 to 4.000 pounds of nitrates a day to the overall flow, accounting for nearly the entire load of algae food. "I think we would have to say the nurseries stand out by far as the major source," he said. Collacott called Skinner's work in the nitrate hunt "sound—] think he's done a real good job." The Skinners — who observed the Orange County businesses and interviewed nursery operators out- side the county — said the usual practice is to sprinkle the plants with a mixture of water and nitro- gen-based fertilizer. Skinner now wants the three nurseries to capture and reuse the nitrate -rich water, a practice that one of the nurseries — Bordier's — already plans to adopt, Collacott said. According to Skinner, some other nurseries around the state al- ready are being required by water boards to control their spillover of irrigation water. Sat Tamaribuchi, Irvine Co. di- rector of waste water and energy, said the company will meet with El Modena and Hines —the two nurs- Saturday, February 8, 1986 The Change County Register 131 ,a erieson Irvine Co. land — later this month to take action on the fertiliz- er runoff. Gutman, however, said he fore- sees no big change in the nursery's strategy. "(The study) will have some impact ... but we're really not reacting to it. We've been work- ing on this the last five years." The Skinners also are asking the Irvine Ranch Water District to speed-up work to curb its nitrate runoff, which they have labeled the second biggest source of the algae explosion, albeit far smaller than the nurseries. Work is behind schedule on a pipeline that eventually will take effluent from the Sand Canyon Reservoir straight to a sanitation treatment plant, plugging most. the flow, according to Skinner. So far, algae has forced no heal precautions in the bay other than the usual enforcement of seasoned mussel- gathering bans, said Rohr ert Merryman, director of the Or ange County Health Care Agency, Harvests now are banned front May to October each year, Meri•¢ -' man said, because the so-called "red tide" toxin develops inside: the mussels as they filter the algae - rich water.

In the worst case, rare pant blooms can monopolize the oxygen of an enclosed waterway, biologists explained- CVO y.. «. 1 WS ttSi.rt' �' �K �+,. f.. 4. •� W' w w uo LL .

Discharge point 002 of the emergency discharge permit however has been relocated from latitude N 330 43' 26 ", longitude W 117° 45, 57" to latitude N 330 43' 1511, longitude W 1170 44' 42 ". This new location discharges directly from Rattlesnake reservoir to Hicks Canyon Wash as opposed to the previous discharge path from the Michelson Plant to Hicks Canyon Wash. The maximum rate of 30 cfs per discharge point will remain the same. IRWD has recently joined in an agreement with the County Sanitation Districts of Orange County (CSDOC). Under this agreement CSOOC will treat and dispose through an ocean outfall, up to 32 MGD of wastewater. IRWD has the option to reclaim less wastewater to match the lower irrigation demand during the winter months. Once construction for this undertaking is complete, the need for emergency discharge will be greatly reduced. Under the current mode of operation, both Sand Canyon and Rattlesnake reservoirs are used for reclaimed water storage during the winter months and provide peaking capacity during the summer months. Unfortunately, the reservoirs receive significant runoff during the normal rainfall years and excessive runoff during wet years, causing discharges which eventually reach Upper Newport Bay.

Box D -1 Irvine, CA 92716 Dear Mr. Bruington: GEORGE DEUKMEAA14, Ge I' As you know, waste discharge Ord& No. 81 -114 expires on September 1, 1985. The discharge covered by this order is for emergency discharges to San Diego Creek resulting from rain storm events. We have reviewed our files regarding discharges made to San Diego Creek. The file indicates that discharges to San Diego Creek have been made contrary to the condition allowed in the Board's Order. Mi-. Ronald Youngs letter of February 23, 1984 indicated that the discharge could be eliminated before September 1985. However, Mr. Young's letter in June 1984 did not turn the corner on this subject and progress at eliminating this discharge is still subject of continued nego- tiations. Discharges to San Diego Creek, contrary to permit conditions, are violations which we cannot alloy: If dry weather discharges to the Creek persist, we will have no alternative left but to initiate appropriate enforcement action against the District including but not limited to Cease and Desist action. It is staff's position that ample time has been extended to the District to elimi- nate the need for this discharge. Consequently, we think it only fair to you to indicate at this stage our intentions. Should the need arise to request renewal of this permit, staff would not at this stage recommend to the Regional Board to reissue the permit. This would prohibit the discharge which in effect will comply with the State Bays and Estuaries Policy. The next status report for completion of the project to eliminate the discharge is not due until March. 15, 1985. In the interim, we encourage the District to keep us informed of any progress in.negotiations. Sincerely, JAMES W.

The applicant proposes to discharge treated municipal wastes to San Diego Creek on an emergency basis. On the basis of preliminary staff review and application of lawful standards and regulations, the Board proposes to adopt waste discharge requirements for the discharge. The discharge and proposed determinations are described more fully below. The application, related documents, proposed effluent limitations, and special conditions, comments received, and other information are on file and may be inspected at the Board staff office at any time between 8:00 a.m. and 4:00 p.m., Monday through Friday. Copying of documents may be arranged by contacting the Board staff. The proposed staff determinations are tentative. Persons wishing to comment upon or object to the proposed determinations are invited to submit same in writing to the above address no later than May 1, 1981. All comments or objections received prior to May 1, 1981, will be considered in the formulation of final determinations regarding the application. If no objections are received, the Regional Board shall make a final determination within 90 days. As described more fully below, a public hearing may be held if response to public notices indicates significant public interest. Description of the Proposed Discharge: The applicant proposes an emergency discharge of treated municipal wastewater to San Diego Creek during wet weather. San Diego Creek is tributary to Upper Newport Bay. The current "Water Quality Control Policy for the Enclosed Bays and Estuaries of California ", adopted by the State Water Resources Control Board on May 16; 1974, and the Water Quality Control Plan for the Santa Ana Region prohibit any new discharge of municipal wastewater to bays and estuaries unless it can be shown that the discharge will enhance the quality of the receiving waters. Reclaimed wastewater will be released from the District's two reservoirs during stormwater runoff periods.

Safeguard to electric power failure: a. The discharger shall, within ninety (90) days of the effective date of this permit, submit to the Regional Board and the Regional Administrator a description of the existing safeguards provided to assure that, should there be reduction, loss, or failure of electric power, the discharger shall comply with the terms and conditions of this order. Such safeguards may include alternate power sources, standby generators, retention capacity, operating procedures, or other means. A description of the safeguards provided shall include an analysis of the frequency, duration, and impact of power failures experienced over the past five years on effluent quality and on the capa- bility of the discharger to comply with the terms and condi- tions of the order. The adequacy of the safeguards is subject to the approval of the Regional Board. b. Should the treatment works not include safeguards against reduction, loss, or failure of electric power, or, should the Regional Board not approve the existing safeguards, the discharger shall, within ninety (90) days of the effective date of this order or within ninety (90) days of having been advised by the Regional Board that the existing safeguards are inadequate, provide to the Regional Board and the Regional Administrator a schedule of compliance for providing safeguards such that in the event of reduction, loss, or failure of electric power, the permittee shall comply with the terms and conditions of this permit. The schedule of compliance shall, upon approval of the Regional Board, become a condition of this order. - S- 3. The laboratory which performs the sample analyses must be identified in all monitoring reports submitted to the Regional Board Executive Officer and the Regional Administrator (EPA). 4. Effluent samples shall be taken downstream of the last addition of waste to the treatment or discharge works where a representative sample may be obtained prior to mixing with the receiving waters. 5. All monitoring instruments and devices used by the discharger to fulfill the prescribed monitoring program shall. be properly maintained and calibrated as necessary to ensure their continued accuracy. C. General Reporting Requirements 1. The discharger shall submit to the Board on or before each compliance report date, a report detailing his compliance or noncompliance with the specific schedule date and task. If noncompliance is being reported, the reasons for such noncompli- ance shall be stated plus an estimate of the date when the discharger will be in compliance. The discharger shall notify the Board by letter when he has returned to compliance with the time schedule. 2. In the event the discharger does not comply or will be unable to comply with any prohibition, daily maximum effluent limitation, or receiving water limitation of this order for any reason, the discharger shall notify the Executive Officer by telephone (714)684 -9330 as soon as he or his agents have knowledge of such noncompliance, and shall confirm this notification in writing within two weeks. The written notification shall state the nature, time, and cause of noncompliance and shall describe the measures being taken to prevent recurrences. 3. This Board requires the discharger to file with the Board within ninety (90) days after the effective date of this order a technical report on his preventive (failsafe) and contingency (cleanup) plans for controlling accidental discharges and for minimizing the effect of such events. The technical report should: a. Identify the possible sources of accidental loss, untreated waste bypass, and contaminated drainage_ Loading and storage areas, power outage, waste treatment outage, and failure of process equipment, tanks, and pipes should be considered. b. Evaluate the effectiveness of present facilities and procedures and state when they became operational. Describe facilities and procedures needed for effective preventive and contingency plans. C. Predict the effectiveness of the proposed facilities and procedures and provide an implementation schedule containing interim and final dates when they will be constructed, imple- mented, or operational. (Reference: Sections 13267(b) and 13268, California Hater Code.) -7- facility by more than 10 percent. Such notification shall include estimates of proposed production rate, the type of process, and projected effects on effluent quality. Notification shall include submittal of a new report of waste discharge and appropriate filing fee. 9. The discharger shall notify the Board of (a) new introduction into such works of pollutants from a source which would be a new source, as defined in Section 306 of the Federal Water Pollution Control Act, or amendments thereto, if such source were discharging pollu- tants to the waters of the United States; (b) new introductions of pollutants into such works from a source which would be subject to Section 301 of the Federal Water Pollution Control Act, or amend- ments thereto, if it were discharging such pollutants to the waters of the United States; (c) a substantial change in the volume or character of pollutants being introduced into such works by a source introducing pollutants into such works at the time the waste discharge requirements were adopted. Notice shall include a description of the quantity and quality of pollutants and the impact of such change on the quantity and quality of effluent from such publicly owned treatment works. A substantial change in volume is considered an increase of 10 percent in the mean dry- weather flow rate. The discharger shall forward a copy of such notice directly to the Regional Administrator. P. Reporting Requirements for Monitoring 1. For every item of monitoring data where the requirements are not met, the discharger shall submit a statement of the actions undertaken or proposed which will bring the discharge into full compliance with requirements at the earliest time, and shall submit a timetable for such corrective actions. The discharger shall submit such informa- tion, in writing, within two weeks of becoming aware of noncompliance. 2. By January 30 of each year, the discharger shall submit an annual report to the Board. The report shall contain both tabular and graphical summaries of the monitoring data obtained during the previous year. In addition, the discharger shall discuss the compliance record and the corrective actions taken or planned which may be needed to bring the discharge into full compliance with the waste discharge requirements. 3. The discharger shall maintain records of all sampling and analytical, results, including strip charts; the date, exact place, and time of sampling; the analyst's name; analytical techniques used; and results of all analyses. Such records shall be retained for a minimum of three years. This period of retention shall be extended during the course of any unresolved litigation regarding this discharge or when requested by the Board. Monitoring results shall be submitted on forms provided by the Board. 4. The discharger shall file with the Board technical reports on self - monitoring work performed according to the detailed specifica- tions contained in any Monitoring and Reporting Program as directed by the Executive Officer. M samples which may be taken in any calendar day. If a composite sample is taken, Ci is the concentration measured in the composite sample and Qi is the average flow rate occurring during the period over which samples are composited. 2. The "30 -day, or 7 -day, average" discharge is the total discharge by weight during a 30, or 7, consecutive calendar day period, respec- tively, divided by the number of days in the period that the facility was discharging. Where less than daily sampling is required by this permit, the 30 -day, or 7 -day, average discharge shall be determined by the summation of all the measured discharges by weight divided by the number of days during the 30, or 7, consecutive calendar day period when the measurements were made. If fewer than four measurements are made during a 30, or 7 -day, consecutive calendar day period, then compliance or noncompliance with the 30, or 7, day average discharge limitation shall not be determined. For other than 7 -day or 30 -day periods, compliance shall be based upon the average of all measurements made during the specified period. If fewer than four measurements are made during the period, compliance shall be based upon the last four consecutive samples. 3. The "daily maximum" discharge means the total discharge by weight during any calendar day. 4. The "30 -day, or 7 -day, average' concentration, other than for fecal or total coliform bacteria, is the arithmetic mean of measurements made during a 30, or 7, consecutive calendar day period, respec- tively. The "30 -day, or 7 -day, average" concentration for fecal or total coliform bacteria is the geometric mean of measurements made during a 30, or 7, consecutive calendar day period, respectively. The geometric mean is the nth root of the product of n numbers. If fewer than four measurements are made during a 30, or 7, consecutive calendar day period, then compliance or noncompliance with the 30, or 7, day average concentration limitation shall not be determined. 5. The "maximum daily" concentration is defined as the measurement made on any single grab sample or composite sample. 6. A "grab" sample is defined as any individual sample collected in less than 15 minutes. 7. A composite sample is defined as a combination of no fewer than eight individual samples obtained over the specified sampling period. The volume of each individual sample shall be propor- tional to the discharge flow rate at the time of sampling. The compositing period shall equal the specific sampling period, or 24 hours, if no period is specified. -11- California Regional Water Quality Control Boar O V Santa Ana Region Monitoring and Reporting Progra4Nr NPDES No. CA 0106844 for Irvine Ranch Water Dist Emergency Stream Disc Orange County Monitori g1 The discharger shall inf oa d prior to any such discharge, if possible, b lat than 24 hours after initiating any such discha e The discharg sll su it a monthly report by the 10th of the month owing any emergency discharge.

BROWN )R., Go.,er,nnr This is in response to your letter of May 14, 1981 regarding the proposed emergency discharge of treated wastewaters by Irvine Ranch Water District (.IRWD). Although originally scheduled for the Regional Board's June 12, 1981 meeting, the item has been removed from the agenda at the request of IRWD. No new date for consideration has been set. If and when it is, you will be informed. Our response to your comments on proposed Order No. 81 -114 are as follows: 1. Unfortunately, the fact sheet accompanying the proposed order apparently was misleading on describing the "emergency ". The emergency does not threaten the integrity of the dams. Therefore, we do not believe involvement of the Division of Safety of Dams is necessary. Rather the emergency pertains to the threat of damage downstream of the dams from a uncontrolled spillway dis- charge. 2. Considering the level of treatment provided the wastewater prior to storage in the reservoirs, we do not believe that specific quality monitoring is necessary. We feel that at the times when. the discharge would be permitted, the naturally occuring conditions in San Diego Creek would not be materially affected. However, if it is warranted, the monitoring programs could be modified at any time to include collection of specific data to determine if the discharge is creating a nuisance or pollution. 3. Because the discharge is prohibited except during periods of threatened overflow of the reservoirs (Provision C. 3.), we do not believe the permit could allow IRIAD to use it to avoid construction of the proposed interceptor or other facilities to regulate and dispose of the reclaimed wastewater. Any discharges during dry weather would be a violation of the permit and enforcement action would be taken. In addition, IRWD is treating and reclaiming a considerable portion of their effluent and is studying a project to inject additional quantities of reclaimed wastewater for subsequent reuse. In a water deficient area such as Southern California we believe that such reclamation practices should be encouraged and commended. I Mr. M. Storm -2- June 11, 1981 4. We have discussed the applicability of the Bays and Estuaries Policy with the legal staff of the State Water Resources Control Board. According to information received the proposed discharge could be allowed when there is no other alternative except an uncontrolled overflow. I hope we have adequately responded to your comments. If not, please let us know. Thank you for your interest and assistance in water quality control. Sincerely, jkke,ng Signed by JAMES W.

These potential adverse effects remain to be cause for concern by the Agency. Recent meetings and discussions with Mr. Bruington and members of his staff, however, have pro- vided new insight into the rationale supporting the IRWD permit application. The committment of IRWD to construct an interceptor to the CSDOC ocean outfall for discharge of wastes is of particular importance in mitigating possible environ- mental damage to the upper bay and watershed. Mr. Bruington has assured me that capacity rights have been acquired and that the interceptor will be completed in approximately 31� years. All non - reclaimed wastes will be routed to the out-fall upon completion of the interceptor. In view of this committment, EMA staff will work closely with IRWD and the staff of your Board to provide proper evaluation of scientific data generated by the activities permitted under these tentative orders, should they be adapted. In order to accomplish this effectively, revision of the existing County Industrial Waste Permit (No. 140) for IRWD will be necessary. Provisions in the amended County Permit No. 140 will be "in concert" with the provisions of the tentative orders 81 -99 and 81 -114. In addition, the provisions will be submitted for comment to the staff of your Board prior to final approval by this Agency. Revision will be made with input from IRWD staff, however, certain monitoring requirements will be augmented and a definite time frame for the waste discharges will be established to coincide with completion of the outfall interceptor within 315 years. The staff of your Board will be notified of any permit violations and /or environmental damage to the Upper Bay and water- shed which may be caused by the discharges. Thank you for the opportunity to review and comment on these tentative orders. If you have any questions concerning the testimony, please contact D.R.

July 10, 1981 California Regional Water Quality Control Board - Santa Ana Region 6809 Indiana Avenue, Suite 200 Riverside, CA 92506 Attention: Mr. James W. Anderson, Executive Officer RE: Waste Discharge Order 81 -114 (NPDES Permit No. 0106844) Application for Emergency Stream Discharge Gentlemen: The Irvine Ranch Water District is submitting the following information for inclusion in Item 14, page I -4 of the permit application. This information answers concerns raised during the review process, and to clarify the purpose of the permit. As you know, the District has lost approximately two - thirds of the usable storage capacity in Rattlesnake Reservoir due to potential seismic insta- bility in the upstream face of the dam. Extensive testing and subsequent evaluation by the Division of Safety of Dams has determined the safe oper- ating level at 390 ft. elevation or a capacity of 470 AF. This is a loss of 973 AF of essential winter storage. Because of the loss of Rattlesnake Reservoir the much smaller Sand Canyon Reservoir has become the primary storage reservoir. Besides its smaller size Sand Canyon Reservoir was built to trap runoff from a large watershed. The recent heavy rain years have shown that the reservoir spillway could be crested during any major storm event. Whereas the dam itself is not damaged during spillover the spillway channel suffers considerable erosion necessitating expensive repairs. The purpose of this permit is to keep Rattlesnake Reservoir from rising above 390 feet and to keep Sand Canyon Reservoir from uncontrolled discharge over the spillway. To alleviate winter storage problems the District has decided to utilize its purchased capacity in the Orange County Sanitation District's ocean outfall. The District has already selected a consultant (CH2M -Hill) to complete the design of the interceptor. If negotiations with Orange County Sanitation District are completed as scheduled, we would expect to authorize CH2M -Hill to begin design in September 1981. The design and environmental review processes, together with development of plans and specifications, are expected to be complete by December 1982. Construction would commence around March 1983 with the interceptor being operational two years later, or March 1985.

These documents address the following IRWD activities which are presently permitted by your Board: . 1. Experimental Stream Discharge (Regional Board Order No. 81 -99, EMA Permit No. 207). --�2. Emergency Waste Discharge (Regional Board Order No. 81 -114, EMA Permit No. 208). 3. Discharge of Treated Wastewater (Regional Board Order No. 76 -49, EMA Permit No. 210). The attached draft permits provide supplemental requirements to your Board orders for the above IRWD activities. The additional EMA requirements will provide for better correlation of data generated by the IRWD waste discharge monitoring activities with data routinely gathered by EMA. This should al- low for better evaluation of the water quality impacts of the waste discharges. In addition, expiration dates for the permits allowing discharge of wastes to San Diego Creek and its watershed are established to coincide with the com- pletion of the IRWD interceptor to the CSDOC ocean outfall. Conversations with IRWD staff have indicated that the additional permit requirements are acceptable. The City of Irvine Industrial Waste Ordinance (for which EMA has been named enforcement agency) specifies that action must be taken on permit applications within thirty days of receipt of application.

During the processing and adoption of our Stream Augmentation Permit No. 81 -99 and our Emergency Discharge Permit No. 81 -114,` several references were made to the District's plans to construct a minimum 15 mgd ocean outfall. The purpose of the outfall was to eliminate our winter effluent storage problem. Our Board of Directors approved the concept of the outfall and work commenced. Several months later a new concept to alleviate our storage problem was presented. This concept involves sending raw sewage to the Orange County Sanitation District for final processing and disposal through their ocean outfall. This concept also involves the formation of a new County Sanitation District. On April 26 our Board of Directors authorized an expenditure in the amount of $200,000 to study this concept. The results of this study will be used to make a decision on how best to proceed thereafter. The estimated time period for formation of the new District and construction of initial delivery facilities is not less than four years. On Wednesday,.April 28, a presentation of this concept was made to the txecutive Committee of the Orange County Sanitation District. The Committee voted unanimously to support our request for cooperation during the study period. We feel these two recent significant events warrant a communication to you con- cerning this change in direction. We will keep you advised of our progress and any significant event(s) that alters our current plans_ lie appreciate the cooperation and help you have provided relative to this matter and hope that this new concept and direction is acceptable to you. If you wish to discuss our plans in more detail we would be pleased to meet with you. Sincerely, �y William M.

The IMID also discharged reclaimed water from the Hicks Canyon wash/ Culver discharge point on January 29 and 30 in anticipation of heavy rains and excessive runoff. The IMID previously agreed to maintain a minimum of 250 acre feet of freeboard in Sand Canyon Reservoir to allow adequate room in the reservoir for storm water runoff to prevent damage to the reservoir spillway. The freeboard at Sand Canyon Reservoir prior to 1 -27 -83 was 263.5 acre feet. Discharge and monitoring will be in accordance with Order No. 81 -114. Sincerely, IRVINE RANCH WATER DISTRICT, John A.

CA0106844) COMPLIANCE REPORT Dear Mr. Anderson: Provision 6 of the Emergency Stream Discharge Permit (81 -114) outlines a compliance schedule for Irvine Ranch Water District (IRWD) to design and construct an interceptor to the Orange County Sanitation Districts to dispose of treated wastewater during period of low irrigation demand. The District began serious negotiations with the Sanitation Districts in early 1982. The cooperative attitude exhibited by both the Sanitation Districts and the IRWD has lead.to a detailed study to form a new Sanitation District along the lines of the one originally proposed for the IRWD service area in the 1960's. When IRWD approached the Sanitation District, the purpose was to formulate the necessary agreements for IRWD to connect to the ocean out - fall in quantities up to the 15 MGD which IRWD had purchased during the con- struction of the outfall. From this beginning, discussions expanded to in- clude the feasibility, both institutional and economic, of treating waste- water at the Sanitation Districts in lieu of building additional treatment capacity in the IRWD service area, as well as utilization of the outfall for the disposal of excess treated wastewater. This multi- disciplinary approach gives the IRWD greater flexability in providing for the future needs in the most reliable and economic manner consistent with all current and proposed regulatory requirements. The expanded agenda of discussions with the Sanitation Districts has required a significantly greater planning effort than was originally invisioned. At the onset of negotiations with the Sanitation District it was expected that a simple agreement to utilize purchased capacity could be realized in a short period of time. However, the present negotiations involving both treatment and disposal have created a complex set of treatment and disposal alternatives that require detailed engineering and economic analyses to choose the alternative most beneficial to both agencies. As a result, the IRWD is still in the planning stage actively pursuing a comprehensive treatment and disposal agreement with the Sanitation Districts. Mr. James Anderson July 19, 1983 SE 8.81 -114 Page 2 of 2 When agreement with the Sanitation Districts is reached the IRWD will have garnered treatment reliability and permit compliance capabilities far be- yond the original concept. The IRWD expects agreement with the Sanitation Districts to be reached by December 1983.. If you have any questions please do not hesitate to call.

Anderson, Executive Officer Regional Water Quality Control Board Santa Ana Region 6809 Indiana Ave, Suite 200 Riverside, CA 92506 SUBJECT: Waste Discharge Order 81 -114 (NPDES Permit #0106844) Status Report Dear Mr. Anderson: Pursuant to the requirements of the subject Order, this letter is to inform you of IRWD's progress in completing a connection between IRWD and the County Sanitation Districts of Orange County's ( CSDOC) ocean outfall. As you will recall, IRWD was anticipating initiation of design of an Interceptor between IRWD's Michelson Water Reclamation Plan (MWRP) and CSDOC's ocean outfall in Huntington Beach during Fall 1981. If that schedule had been pursued, and allowing three and one half years for design and construction, then the Interceptor could have been operational in Spring 1985. However, during Fall 1981 IRWD and CSDOC began discussions concerning institutional methods of affecting a connection between our two agencies, specifically the reformation of County Sanitation District No. 14. The intent of reforming CSD No. 14 is to provide the means for IRWD to join the other existing CSD's in regional wastewater treatment and disposal. To assesses the viability of this wastewater management option, IRWD initiated a study which focuses on the following three alternatives: Treatment at MWRP of all wastewater flows generated within the IRWD sewer service area (currently estimated at 32 mgd), seasonal reclamation up to 15 mgd and ocean disposal of non - reclaimed flow through the Interceptor to CSOOC's ocean outfall. With this alternative, the institutional means of acquiring additional ocean outfall capacity beyond IRWD's existing 15 mgd capacity may or may not dictate the need to reform CSD No. 14. Mr. James W. Anderson 4673REY12/83 December 1, 1983 PR 1.20305 Page 2 SE 8.79 -33 2. Participation with other CSD's in the expansion of CSDOC's wastewater collection system so as to provide a means for IRWD to convey wastewater to CSDOC's Treatment Plant No. 1 in Fountain Valley for treatment and ultimate ocean disposal. IRWD would continue to operate MWRP on a seasonal basis in order to produce up to 15 mgd of reclaimed water. To implement this alternative, CSD No. 14 would be reformed so that flows from IRWD could be provided for in CSDOC's capital and operating budgeting process. 3. A combination, or Hybrid, of the previous two alternatives including year round operation of MWRP up to 15 mgd with reclamation during the summer and ocean disposal during winter through the Interceptor to Huntington Beach. All flow above 15 mgd, as well as solids generated at MWRP, would be conveyed to CSDOC's Treatment Plant No. 1 in Fountain Valley for treatment and disposal. C5D No. 14 would be reformed to the extent that flow from IRWD requires capacity in the CSDOC system. At this time, IRWD has completed most of the analysis necessary to assess these three options. We are now negotiating with CSDOC to identify the details involved with reforming CSD No. 14. The attached schedule running from March 1983 to the present documents the events pursued by IRWD regarding the reformation. We anticipate negotiations running through Winter 1984. IRWD's philosophy is to provide cost - efficient and reliable service to our customers. Therefore, a final decision regarding which alternative to implement will consider capital expenditures, replacement costs and operation and maintenance costs, as well as intangibles such as retention of decision - making authority and exposure to risk due to factors beyond our control. The Regional Water Quality Control Board will be promptly notified of a final decision regarding IRWD's wastewater treatment and disposal issue. Sincerely, IRVI NCH WATER DISTRICT Ronal E.

Box D -I Irvine, CA 92716 Dear Mr. Young: GEORGE DEUKMEJIAN, GGvernf We have received your December 14, 1983, letter regarding the elimination of emergency discharges. It now appears that the discharges will not be eliminated until late 1988 at the earliest. This is a delay of more than three (3) years from the District's original proposal. CJ S' As you are aware, the discharge of treated wastewaters to San Diego Creek is permitted on an emergency basis. The increased frequency of discharge to San Diego Creek, and the apparent protraction in implementing a solution to these "emergency" discharges leads us to believe that what was once an emergency is now standard operating practice. The State's Bays and Estuaries Policy prohibits this type of discharge practice. Before making any enforcement recommendation to our Board, we would like to discuss this with you in our office on February 23, 1984, at 9:00 A.M.

Bennett Supervising Engineer California Regional Water Quality Control Board ` Santa Ana Region 6809 Indiana Avenue, Suite 200 Riverside, California 92506 SUBJECT: WASTE DISCHARGE ORDER NO. 81 -114 Dear Mr. Bennett: Thank you for the opportunity to discuss..your concerns regarding the subject Order. Based on our discussions, IRWD will look into alternative plans to reduce the amount of discharge into the San Diego Creek under the subject permit. I appreciate your time in understanding the history of this permit, and IRWD's efforts to expand its water storage and /or disposal capability for its water reclamation program. The negotiations with the County Sanitation Districts of Orange County (CSDOC) are continuing and as I indicated, have become meaningful in that we are participating in the dual design airport relief trunk sewer as noted in the letter dated February 15 delivered to you. We could provide elimination of discharge into the San Diego Creek before the September 1985 expiration date of the subject permit. In summary, IRWD will make every effort to keep you informed and make progress on this issue. It is my understanding that this will not officially come to your Board's attention until June 1985 when an application to extend or redefine the order including proper environmental documentation would be necessary.

Mr. Ronald E. Young Director of Engineering Irvine Ranch Water District P. 0. Box D -1 Irvine, CA 92716 r Dear Mr. Young: As discussed at our meeting of February 23, 1984, the NPDES permit for the District's emergency discharge to San Diego Creek expires September 1, 1985. This permit was issued in recognition of the fact that it would take some time to completely eliminate the discharge. The reliability of holding capacity in Rattlesnake and Sand Canyon Reservoirs is decreasing as wastewater flows increase and as storm - water and silt deposition occur during wet weather. These conditions remain unmitigated. We were pleased to review the District',s previous planning efforts and we are encouraged by what appears to be a workable alternative, presently being negotiated. However, planning efforts have historically fallen short and progress at eliminating this discharge should be stepped up in accordance with the expiration date of this permit. As required by the permit, a status report is due in this office in June 1984. We will be using this status report as the basis for a report to the Regional Board at the July 13, 1984 meeting. Thank you for your attention on this matter and we look forward to a report indicating substantial progress. Sincerely, .dames R.

CA 92716 - 6025.(714) 833 -1223 April 3, 1984 California Regional Water Quality Control Board - Santa Ana Region 6809 Indiana Avenue, Suite 200 Riverside, CA 92508 -4298 Attention: Mr. James W. Anderson, Executive Officer RE: Order No. 81 -114 NPDES No. CA 0106844 Gentlemen: Please be advised that the Irvine Ranch Water District resumed dicharges under the above order on March 27, 1984. Discharges are currently being made from Sand Canyon Reservoir (Discharge Point 003). This information was communicated by telephone to Mr. Bruce Paine of your office on March 27, 1984. The resumption of discharges was necessitated by the impending overflow of Sand Canyon Reservoir. As you know, all flow from the Michelson Water Reclamation Plant has been diverted to Sand Canyon Reservoir during the ongoing rehabilition of the chlorine contact chamber. Demand from Sand Canyon Reservoir has been less than supply resulting in an increase of water in storage. It is anticipated that discharges will continue until the completion of the chlorine contact chamber rehabilitation. This is scheduled to be complete by April 23, 1984. If you have any questions regardi,rig this matter, please do not hesitate to call me. Sincerely, IRVIN NCH ATER DISTRICT w r Gregory P. Heiertz E.
