CALIFORNIA 95734 TELEPHONE 587 3896 MEMORANDUM TO: Board of Directors r- FROM: Milt Seymour SUBJECT: Board Meeting of June 7, 1977 - Manager's Report. DATE: June 3, 1977 1 . Plans for TDPUD 50th Anniversary Observance: Our 50th anniversary observance will occur on June llth between 10:00 A.M. and 4:00 P.M. We will have the headquarters building open for inspection. Our billing computer will be operating. Our special equipment such as the High Ranger truck and backhoe will be on display. We will also have the Northside Well , Soma Sierra pump station and the Southside Spring and Well complex open for public inspection. I anticipate a minimum of six employees being on duty during those periods to answer questions and assist any visitors. We will have refreshments. 2. SPPC Filing with PUC for Revised Energy Cost Adjustment Clause: Sierra Pacific recently announced an increase in their energy cost adjustment clause (fuel charge) for retail customers in California_ The charge was increased from 1 .084�/ KWH to 1 .153¢/KWH. This fuel charge rate will be in effect until October, 1977, at which time it will either be raised or lowered. Inasmuch as Sierra Pacific is raising their retail fuel charge we can anticipate a similar increase in the wholesale fuel charge. 3. Status Report re SPPC Rate Case Still Pending at FPC (Refund) : As of today we still do not know exactly when the FPC will rule on the roll back of Sierra Pacific's wholesalerate which will result in a refund to us and several other publicly owned power systmes. Based on copies of documents received from the FPC staff it would appear that a ruling is imminent. The problem remains Mt. Wheeler's objection to the settlement agreement. 5. Status Report re R.W. Beck Revised Electric Rules and Regulations: R.W_ Beck has indicated they will be visiting us within the next to weeks to discuss the revised Rules and Regulations particularly Rule 15, Line Extensions. Bill Clouter, the engineer at R.W. Beck who originally was working on this project, has left the firm and a new engineer is taking his place_ The engineer is formally with SMUD's rate department. 6. Billing Procedures: Because of illness, vacations and intensive MEMORANDUM to the Board of Directors Re Board Meeting of 6/7/77 - Manager's Report June 3, 1977 Page 2 customer service activities we have slipped a little bit further behind in our billing. We are currently about three weeks behind. To correct the situation we will be operating the billing machine two days a week on a two shift basis and on Saturday until we are again caught up. I have also asked the software firm to make us a proposal for re-programming the computer to bury the fuel charge so that it does not appear as a separate item on the bill . We are also investi- gating the possibility of an improved bill format that will allow us to use bill stuffers or printed messages to keep our customers better informed. We need to be telling our customers about energy conserva- tion, water conservation, new rates, rules and regulations, etc. MILT MS:jr cc: Steven Grumer �.N0rt mwa rt 0It ro0aarn 10tr0"tr rt rt ry HroHro to p 0 0• ro 0 0 ::r ro P. h ro 0 W H ►i m W'C 0' x m h • ti ;u mina a me 0mrtaa 0 W 0m a 0 art • 00 rt Oro 00 c 0 P.P.rt V•ro ::r 0 h 0 00 H P.m0 w mw00m 0hm0 H N. xrn ei 0 0 m h 0 0 h 0 H. to m m G H6 N N rt rt K Vt rt rt rt HF'N in a m wm rt 0 �'a s 0 w Fl-— x trJ • N•a m > rt rt 0 1 rt • rt 03011 E :3 m00ft :tr5 :3 a •• x00 rtM m rttAa a taw 4MNxm Fl-0rt x 00 :rH hx w m —En 0 __ rh rtm0H rt0 to m0H aw0 - amH m 0rt a 0P.

The Court found the explanation insufficient since no detail was given as to how the mistake occurred. on the other hand, it is doubtful that the District could force Slater into performing the work. It has often been held that where a bond accompanies the bid, the only recourse is a forfeiture of the bond amount. In A & A Electric, Inc. v. City of King, supra, the Court held as follows: "The city, in its cross-complaint, seeks not only a forfeiture of plaintiff's bid bond but also damages for breach of contract for the dif- ference between plaintiff's erroneous bid and the next lowest bid. The city cites no authority per- mitting such recovery and we find none. [7] Although provisions for forfeitures in the nature of a penalty are generally not favored (Petrovich v. City of Arcadia (1950) 36 Cal .2d 78, 84, 222 P.2d 231) , "the right of municipalities to require guarantee deposits to accompany bids, and to forfeit them in the event of the failure or refusal of the successful bidder to enter into the contract, has long been upheld. " (Palo and Dodini v-. City of Oakland (1947) 79 CaLApp.2d 739 , 747, 180 P.2d 764, 769. ) Such, "provisions requiring a deposit accompany- ing a bid for city contracts, or for forfeiture thereof, are necessary as a matter of public policy. (Id. at p. 750, 180 P.2d at p. 771. ) The specific statutory procedures for the presentation and forfeiture of bid bonds relating to a bid on a city project are found in Government Code sections 37931-37933. [8] Pursuant to its authority the City of King in its instructions to bidders called for 'a 10 percent bond to be forfeited as liquidated damages if the bidder refused to enter into the contract. By its own instruc- tions to bidders defendant clearly limited the obligation of the bidder to the amount of the bond. "The wording of the bid invitation and the executed bid was of the city' s own choosing and should not be held to extend the bidder' s and the surety's hazards beyond its fair meaning. [Citation. ] " Petrovich v. City of Arcadia, supra, 36 Cal.2d at p. 85, 222 P.2d at p. 236. ) t We hold the city may recover the amount of the bond but is not entitled to damages for breach of. contract. d Pat Sutton, President Page Three ' June 6, 1977 Therefore, if Slater Electric persists in its refusal to perform for the bid price, the District can only recover the amount of the bond and accept the second lowest bid.

Drawer G Truckee, CA 95734 Dear Mr. Whitford: I have reviewed the proposed Sanders Well site and well design sketches. The well will be drilled for the Truckee-Donner P.U.D. The one-acre site near the intersection of Interstate 80 and State Highway 89 is suitable for a domestic water well. The proposed well design is acceptable if the surface construction features as outlined in Department of Water Resources Bulletin No. 74 Water Well Standards are included. (Copy enclosed). The well must be properly disinfected before it is placed in operation. Waterworks standards require a metering device be installed on each water source. If you wish I will be glad to discuss these recommendations with you. Sincerely yours, Lloy R. He an Senior Sanitary Engineer Sanitary Engineering Section LRH:as cc: Nevada CHD Truckee-Donner PUD Encl. April 7, 1977 �^ Mr. Milton Seymour, Manager ` Truckee Donner Public Utility District Post Office Box 309 Truckee, Ca 95734 Dear Milt, A few months back, I had the opportunity to review the District ' s comprehensive health plan in brief. At the time, I felt that the plan could be improved with little or no increase in cost- to the District . Following, is my analysis of the current employee health program and my recommendations concerning that program. ANALYSIS OF CURRENT HEALTH PROGRAM Blue Cross Hospital Plan : This is one of the best hospital care plans in existence today. The benefits provided for the dollar outlay are outstanding. Blue Cross has various agreements with hospitals of all kinds to provide services and those hospitals bill Blue Cross direct . The employee does not become involved in either the billing or claim payment process . Blue Cross Surgical/Major Medical Plan : Rarely is one best at all things and, as your employees are aware, the out-of- hospital benefits are Blue Cross ' s weakpoint . The basic benefits are, in some cases , well below what is currently being charged in your area_ What ' s left is then paid at 80% under the Major Medical (MM) . The process of getting payment to the Phxysician, the Laboratory, or the employee is often laboriously slow. Blue Cross Dental and Prescription Drug Plan : The benefits and costs are certainly well within the competitive average. The Prescription Drug Plan is expecially nice since Drugs will usually fall within a deductible and thus are -rarely reimbursed . OUR RECOMMENDATIONS Blue Cross Hospital Plan : We recommend the District continue this program. Money cannot buy a better hospital plan. Blue Cross Dental and Prescription Drug Plan : These are 3445 AMERICAN RIVER DRIVE, SUITE B — SACRAMENTO, CA 95825 — 916/483-9202 Truckee Donner P .U. D. - Page 2 also very good programs; no one ' s interest would be served by changing them. B1ue .Cross Surgical/Major Medical Plan : This is not only the one area where change is possible, it is the area where quite surprising changes can and should be made . And, at what should be considered, no increase in cost . ANALYSIS OF RECOMMENDED CHANGES The Blue Cross Surgical/MM plan provides a benefit for surgery and anesthesia that is about 70% of current charges . most other out-of-hospital benefits are covered under the MM at 80% after a 100 dollar deductible . We recommend the District adopt the Guardian Life Wrap-Around Plan which has been specifically designed for use with the Blue Cross Hospital Plan. Surgical benefits are paid at 100% of reasonable and customary charges . All other out-of-hospital benefits are paid at 100% after a $100 dollar deductible. Claims are paid promptly and in full . Physicians and Laboratories readily accept Guardian coverage . The maximum out-of-pocket cost by an employee should be $100 a year, if he or she has a family,. the maximum cost should be $300: In most cases it will be much less, depending upon the services used and how often. This one change will give the District and its employees the best Insured Health Plan in the United States todayl ANALYSIS OF MONTHLY COSTS Blue Cross Blue Cross/Guardian Hospital Plan $45 . 26/empl Surgical/MM Plan $72 . 18/empl $26 . 66/empl Dental Plan $13 . 97/empl $13 . 97/empl Prescr Drug Plan $ 5 . 27/empl $ 5 . 27/empl Total for Health Plan $91 .42/empl $91 . 16/empl Life Insurance : $7, 500 per empl $10, 000/employee No A. D. $D. $10, 000 A.D . $D. No Dep coverage $ 1 , 000 ea Dependent Est cost $50/month $76 . 16 a month Truckee Donner P. U. D. - Page 3 The actual cost for Health Plan benefits would decrease about $4 a" month. However, when the Guardian Group Life Benefits are added, the total cost for all benefits increases about $20 a month. "The Group .Term benefits under Guardian are at least 1/3 better, not considering the Dependent Life benefit . We have had 4 years of experience with Guardian Insurance plans and with the Guardian/Blue Cross Wrap-Around . Their record is excellent . We have never had to shop around for better rates, we have never had a complaint on claims payments and we have never had a client switch to another health Insurance carrier after having installed one of these programs . We did obtain one other quote for a wrap-around from Crown Life. Their cost was $36 . 56 a month per employee, or nearly . $10 a month per employee higher. Their Major Medical is only an 80% rather than than Guardian ' s 100% . The total package, should be clearly in a class by itself.

Carson Treasurer Nevada County 201 Church Street Nevada City, Ca. 95959 Re: West River Street Assessment District, Truckee-Donner Public Utility District Dear Marcella: You recently received a letter from Mary Chapman. The letter included a resolution by the Board of Directors of the Public Utility District. That resolution is pretty much self-explanatory. There is a surplus in the improvement fund of the project and the proceedings provide for the distribution of that surplus under Section 10427 et seq. , of the Streets and Highways Code. Since the County is handling collection of assessments and fund- ing for the District, the surplus should be credited against the assessments in the manner which they have been set forth by Dan Cook. For those parcels which are still on the roll, the upcoming tax bills should be credited in the amounts shown. If those amounts are larger than the amount on the tax bill, then the balance of the credit should carry over to the next tax payment. Anyone who has made payment in cash should have a cash refund. We are doing some preliminary work on a proposed SAD 5 district- which probably doesn't thrill you, but which I look forward to as it will give us an opportunity to renew our friendship with Nevada County.

In February of 1971 DART Industries, Inc.. assumed the rights and obligations of Lakeworld under the agreement with the concurrence of the District. In 1973 it became evident that the two parties were unable to guarantee that the Donner Lake water source contemplated in the 1970 agreement would be available. Dart and the District entered into a supplemental agreement on October 15, 1973. The purpose of this supplemental agreement was to allow the District and Dart to study and provide for alternate water sources and facilities for the Tahoe Donner Development. Now in 1977 it appearsthat an amendment to the 1973 supplemental agreement may be in order. The majority of persons on both sides who will be involved in the negotiations to amend the 1973 supplemental agreement have not been involved in the water source and facilities development for Tahoe Donner since its beginning with the 1970 agreement. This report will provide selected background information for both parties to refer to during negotiations to resolve the amendment of. the 1973 Supplemental Agreement. Scope and Limitations This report will provide information concerning Tahoe Donner's water requirements including .annual, maximum day and peak hour use, water storage at Tahoe Donner, existing well system capabilities and how all of the above relate to the quarterly water use projection. There will undoubtably be need for information other than that provided in this report during the negotiations for the amendment to the 1973 Supplemental Agreement. Subjects presented herein have been selected by Dart for presentation by Cranmer Engineering, Inc. ' because of our particular background in these areas with the Tahoe Donner Development. Some of the data presented is technical in nature however it is considered as basic, essential information for anyone influential in the planning for a water source development program of this nature. Sources of Information LA Reports, plans and design information for almost all facilities at Tahoe Donner are on file in the office of Cranmer Engineering, Inc. This firm has been the prime consul- tant utilized by the developer of Tahoe Donner since design began in early 1971. 1 CHAPTER 2 WATER REQUIREMENTS FOR TAHOE DONNER �^ General A proper understanding of several terms used and how various facilities work together is essential in understanding and solving the problems associated with formulating a water source development program. Terminology "Average annual demand" - an average flow rate expressed in gallons per minute (G.P_M.) arrived at by dividing the total number of gallons used in one year by the number of minutes in a year. Considering Tahoe Donner at ultimate development we have the following: First calculated by Keenlen in Draft E.I.R. Tahoe Donner Annual Water Requirements for Application by T.D.P.U.D. to Lease State 6515 units @ 0.29 acre-ft/unit = 1889 acre-ft. Land and Divert Water From Donner Lake Golf Course = 142 TOTAL 2031 acre-ft 2031 acre-ft. = 661,758,293 gallons Therefore average annual demand = 661,758,293 = 1259 G_P.M_ (365) (24) (60) "Average demand on maximum day" - an average flow rate expressed in gallons per minute (G.P.M.) arrived at by dividing the total number of gallons used during the one day of maximum use by the number of minutes in one day. Again considering Tahoe Donner at-ultimate development we have the following: From 1970 agreement: "Provide for average maximum day use of 800 gallons per lot" From EIR for Donner Lake Water Diversion. Developed by Keinlen and DeHorn: 6515 total dwelling units projected at ultimate development of Tahoe Donner. From Joe Williams and Golf Course Water Management Plan prepared by DeHorn: "Gallons per day requirement beyond 1981 in July and August projected to be 297,648 gallons" Avg. Demand Max. Day = (800 x 6515) + 297,648 24 x 60 = 3826 G.P.M. The above figure can be and has been calculated using slightly different information since 1970. In September of 1971 Lloyd Heinzel of the State Department of Public Health suggested that it be rounded to an even 4000 G_P.M. which it has been since that time. �S 2 I i "Peak hour demand" - an average flow rate expressed in gallons per minute (G.P.M.) arrived at by dividing the total number of gallons used during the one hour of maximum use by the number of minutes in an hour. Considering Tahoe Donner at ultimate development we have the following: From Cook Assoc. "Water System Analysis 6515 units @ 1.092 gpm/unit 7,114 G.P.M. Report Oct. 1976" and Golf Course Water Management Plan 600 G.P.M. 7,714 G.P.M. Water Storage On site storage is needed to provide for equalizing peak demands and providing for emergency fire reserve. A more detailed explanation of how storage is combined with pumping capacity to meet peak requirements will be presented later in this chapter. The 1970 agreement required the following: "Provide storage tanks for domestic and fire protection use (including emergency requirements) equivalent to a total of 2.8 million gallons for the entire proposed 6,000 lots or 466.66 gallons per lot." Figure 1 shows graphically how the total storage at Tahoe Donner is allocated to domestic equalizing, golf course equalizing and fire emergency purposes. Table 1 shows a complete breakdown of how storage for the various purposes is distributed between the eleven onsite storage tanks. Water Source Capacity vs. Water Demand Earlier in this chapter three demand rates were defined and determined as follows: Average Annual Demand 1259 G.P.M. EN Average Demand on Maximum Day 4000 G.P.M. Peak Hour Demand 7714 G.P.M. Figure 2 has been developed to provide a further understanding of how these demand rates fit into the constantly changing demands during a typical year. A IL water source for Tahoe Donner must be capable of providing at least the total amount of water equal to the average annual demand of 1259 G.P.M. flowing all year long or 661,700,000 gallons. In addition to this the source must have water available in varying amounts during different times of the year. For instance the average monthly demand in April is well below 1000 G.P.M. During August, however, the average monthly demand will exceed 2500 G.P.M. and by examining the graphs in the lower part of Figure 2 it can be seen that there will be one day in August "the maximum use day of the year" when the average demand is 4000 G.P.M. During that day there is a peak hour demand of over 7700 G.P.M. Without equalizing storage it would be necessary for the pumping capacity placed at the water source to meet this demand. Equalizing storage reduces the need for pumping capacity to the average demand on the maximum day in the following manner. Examine the graph in Figure 2 which shows the maximum i� day variation by hour. Imagine the source being pumped at the average demand on that maximum day or 4000 G.P.M. Beginning at midnight and during the early morning hours the demand is less than that being supplied and the storage tanks are being filled. By midmorning the demand exceeds the supply which is now supplemented by flow from the storage tanks. This continues until early evening when demand again is less than that being supplied and the storage tanks begin filling again. 3 I DOMESTIC EQUALIZING STORAGE 1,190,000 GALLONS GOLF COURSE EQUALIZING STORAGE 440,000 GALLONS FIRE EMERGENCY STORAGE 1,020,000 GALLONS 1 ON SITE WATER STORNGE AT TAINOE DOWNER TOTAL ON SITE STORAGE 10a 2,b50,000 GALLONS ON SITE TRAILSTOTAL STORAGE PROVIDED BY DART lS (2b5O,000 GAL) (DONNER 150,000 GAL. - 2.800000 GA FIGURE 1 .

A common misconception with respect to the water source capacity requirement is that there must be an ability to pump 4000 G.P.M. continuously all year long. The_ pumping capacity of 4000 G.P.M. of course must be there to meet that one maximum use day during the year. If 4000 G.P.M. were pumped continuously for one year 2,102,400,000 gallons or 6,452 acre-ft. would be removed from the source. This exceeds Tahoe Donner's annual requirement by over 200 percent. Existing Well System Capacity The Northside Well presently has a pumping capacity of 769 G.P.M. According to Dr. John Sharp of Hydro Search the Northside Well can meet average demands on the maximum day in excess of 2000 G.P.M. and can meet an average annual demand in excess of 600 G.P.M. This means that the Northside Well can provide 50 percent of the ultimate source capacity for Tahoe Donner. During a typical year 330,800,000 gallons would be removed from the aquifer. Records indicate that 231,037,000 gallons were removed from the aquifer by the Northside Well in calendar year 1976. Less than half of this amount was delivered to Tahoe Donner. Quarterly Use Water Projection The supplemental agreement requires in part the following: "Dart shall project quarterly the anticipated water requirements of Tahoe Donner for the succeeding two years based on the standards and requirements in Paragraph 1 (a) of the 1970 agreement and inform the District thereof". Cranmer Engineering, Inc. has provided that quarterly projection on behalf of Dart since October 1974. The quarterly projection for the end of the fourth quarter of 1976 presented the following information: Projected buildout rate to be 600 units on December 31, 1978 600 units @ 0.56 G.P.M. = 336 G.P.M. Golf Course = +248 G.P.M. Average Demand on Maximum Day = 584 G.P.M. The above projection is based on a build out rate of 51 units per year. Six years beyond December 1978 would add 6 x 51 = 306 more units. 906 units @ 0.56 G.P.M. = 507 G.P.M. Golf Course = +248 G.P.M. Average Demand on Maximum Day = 755 G.P.M. It can be seen that based on the information available the 769 G.P.M. capacity of the Northside Well should be adequate through the year 1984. It is evident that when the need arises Dart could provide additional source capacity by increasing the delivery rate (pumping capacity) of the Northside Well up to 1300-1500 G.P.M. and ultimately 2000 G.P.M. with the necessary upsized transmission main or develop an additional separate water source. 7
