MANAGER'S ponT
April 16, 1979
1 General Status of the District
ouring the past two weeks, we have had no significant electric or
water outages. ror the Manager' s Report dated April l , 1979, i neglected to
inc/uue the water product ion fiyures For the month or march' They are at-
tached to this report.
Construction activity, primarily of single homes, in the Truckee area
is increasing rapiu!r' we are able to keep up with thc- demand for new electric-
a] services, but are considerably behind in the demand for new water services'
The primary reason For our backlue in the Water Department is the accumulation
of new service orders acquired during the winter months when new water services
were impossible to install . At the present time, our water crews are at least
sixty days behind the uemanu' we antic/pate the hiring of two helpers for the
Water Department to keep up, and indeed make up some of the backlog as the *ann
season approaches.
z Annual R
| anticipate receiving a draft copy of the report within the next few
days. Following the receipt of that, we will then pot together the rules, reg-
ulations and financial oata needed for the balance of the repurt' we hope to
,_- have the body of the report complete enough so that when the auditors complete
their audit and have the annual audit report ready for Board discussion that
we will be able to incoi-porate the essential parts of that into our report'
3. Senior Citizen Housing
This item is on the manager 's Report because | felt it was time to

REPORT TO THE TDPUD BOARD
for the April 16, 1979 Regular iMeeting
FROili: the Water Committee
submitted by: Pat Sutton, Director
The Committee met on April 11, 1979 with Directors Karl Kuttel and Pat Sutton
present. Also present were A. Milton Seymour, General :Manager, and Dan J.
Cook, District Engineer.
BRIEFINGS: FmHA: The Eananager & Engineer indicated that their meeting in
iMarch with Farmers Home Administration was productive, and that the possibi-
lity of another loan for water system improvements looks promising.
DART: There was a brief update on Dart's latest proposals to
provide water to Tahoe-Donner. Dart is requesting Board authorization for
the environmental assessment to begin for a water main from the Norths1de
Well to the Truckee River Crossing. There was also some discussion regarding
the Dart/TTAD agreement on the Airport Well.
PROSSER WELL: There was some discussion about the status of resolving the
Prosser Well problems. M-M. Cook indicated that the next step is his report,
which should reach the Board sometime in Iay.
i.icFARLAiiD QUITCLAIPI REQUEST: (property located on SIVJ corner of I80 & 267,
formerly owned by Gebhardt I:r. Kuttel indicated he believed there could be
unresolved problems with the Truckee Cemetary District regarding this paxcel;
he agreed to consult with Cemetary Board members and report back. Director
Sutton indicated her confusion over the relationship of the current request
to a previous request by Mr. McFarland. Mir. Cook indicated that he is not
familiar with the location of the water line easements in question, and that
he has not seen the survey of record which i1rs. Gebhaxdt had at the ;:arch 19
Board Meeting when he was not present. Mr. Seymour indicated that "staff"
has recommendations to propose.
WELL STANDARDS: There was discussion about the proposed Well Standards for
the District recently prepared by Iir. Cook.
The lack of County Well Standards was noted, and there was discussion of the
District's potential interest in -protecting the community supply by imposing
and enforcing standards for private wells within the TDPUD boundaries.
It was generally agreed by those present that references to private wells
will be expanded by i•ir. Cook, perhaps resulting in a seperate section on
private wells to be included in the District's Well Standards. It was
recognized that some research may be required to determine legal authority
over private wells.
REPORT FROIi WATER COi,UUTT EE
for April 16, 1979 reeting
page 2
Related to this discussion, Director Sutton raised an unresolved question
regarding whether or not the District may have an interest in how water is
provided to subdivisions within its boundaries. She noted her concern that
the District had not been included on the circulation list for the Ponderosa
Estates Draft EIR (a fact she had confirmed) , and that the official agency
comment period had expired before the District became aware that an EIR had
been completed and was circulated for comment.
Discussion then centered on the water quality standards specified in the
proposed Well Standards, their origin and adequacy, and some comparison with
the components of the existing water sources of the District.
Directors Kuttel and Sutton indicated that they felt that the local water
quality standard should be more consistent with the characteristics of the
present sources, and that further input and consideration is necessary in
order to determine a reasonable local water quality standard which can
eventually be recommended to the Board.
Mr. Kuttel will carefully review the proposed Well Standards, and the Committee
will meet again to consider there further.
WATER PROJECTS: There was more discussion of the possible intent of Dart
to construct eventually, two of the major projects (the 267 Intertie from the
River Crossing to the SouthSide Complex.-and the Large Main from the River
Crossing to the Town Tank/N orthside Tank) which the District i`s currently
including in the work to be accomplished through a FmHA loan.
At this point in the discussion, it was recommended by the iianager & Engineer
to keep those projects in the FmHA loan application because both improvements
are needed to insure the integrity of the cormiunity supply regardless of
Dart's needs, the :,,irport Well possibility, etc. The Iiana.ger & Engineer
-^' agreed that these two projects could be deleted at a later date from the
FmHA loan request if the Dart plan materializes in a timely manner.
It was reported by the Engineer that a FmHA loan to be repaid through revenue
bonds would have to be approved by the voters since the emergency legislation
related to the drought is no longer in effect. Director Sutton was asked
to check with the County Clerk regarding deadlines for ballot measures for
elections to be held this year.
Director Kuttel then proposed that the construction of the urgent water
system improvements be funded by use of money from the Electrical Department.
Director Sutton questioned whether this might result in the deletion of so
many items from the FmHA loan application that it would no longer be a
viable source of capital financing for the other water projects that have
been recommended.
REPORT FROle, WATER COMMITTEE f�35-
for April 16, 1979 Meeting
page 3
The Manager indicated that he thought that the Electric Department might
have funds available which could be transferred to pay for the construction
of some projects.
It was finally agreed to recommend to the Board that authorization be given
for the engineering work to prepare the plans and specifications for the
First Priority List items referred to as the "SouthSide Improvements" and
the Tonini Springs Improvement (See Water Committee Report for February 20
Board Meeting).
It was the .engineer's opinion that a water rate increase probably would not
be necessary if an interdepartmental loan was arranged to pay for the construc-
tion of all these projects, and that Water Department Fees (Facilities Fees
and other) would probably be sufficient to pay back the loan as development
takes place.
There was no final determination made by the Committee at this time regarding
a possible recommendation that construction of these water projects be funded
by a loan from the electric utility to the water utility.
1!I SCELLAISOUS: Director Sutton reported that she had established through
inquiry to the Nevada County Planning Department that an Environmental Impact
Report is being prepared at the present time to increase density in the
aMartis Valley. Mr. Cook indicated that he expects to have "the opportunity
to review the preliminary water information and will keep the Board informed.
Director Sutton requested that the Sub-Committee (Sutton/Seymour/Cook) resume
its efforts to finalize the proposed revisions in the Water Rules & Requlations
and the Construction Standards, work on which was discontinued about 1- years
ago. 1.1r. Cook agreed that this effort should be resumed.
r
Director 'r:uttel and Hr. Cook proceeded from the Committee meeting to the-
site west of theTruckee Elementaxy School (the Bezzerides commercial develop-
ment) to inspect it for existing water facilities. This property is the
subject of a request initiated by Don Casler, local real estate agent, for
the District to execute a quitclaim relating to water easements, and about
which there has been some confusion.
ITr. Seymour indicated that he'd place a seperate item on the April 16 agenda
for Doaxd consideration of authorizing the engineering on the SouthSide
Improvements and the Tonini Springs work.
The Committee's recommendation is attached to this report.

Re: Tahoe Donner Water Den.and
Dear Don:
Some. time 'pack Keith Sauers provided a two year project of
water use by the Tahoe Donner. Development for the near term.
The projection was rejected as being inconsistent with past
projections and projected a future flow that was substantially
less than the actual 1978 consumption, a condition that is
Impossible. A revised projection has not been received to
date.
The maxi.mum 6 day July water use at the Tahoe Donner Develop-
merit approached 600 GPM - 6 day average. Peak day usage was
approximately 720 GPM. Consumptive demand fell off in
August as the. temperature dropped off beginning August 10,
1978. MaxillUM-1 .August demands averaged 520 GPM. The Labor
Day peak utilization approached. 650 GPM.
As 1: recall. the 1973 Agreement speaks to peak day demands and
pro roc t:ion.s . Projecting 250 units in 1.979 and 200 units in
1980 will be connected to ttie system, an increased demand of
250 GPM will.. be experienced in the summer of 1980..
Duplicating the 78 expe-ri-once in 1.980 would provide the
following r.estil.ts :
Dori. S trand
Truckee, California
April 2, 1979,

P e r I o(4, Total- Source Demand
July 6 day Average 8 1.0 G PI-I
July Peak Day 970 GPM
August Peak Day 770 GIIJA
Labor Day Weekend Average 590 GPM
Labor Day Weekend Peak Day 900 GPM
The 'North Side Well yielding something in the order of 650 GPM
and well A & B yielding something in the order of 150 GPM
(sustained) total approximately 800 GPM.
I suspect maximum day demand this summer will exceed the supply
by a small margin.. However, the average week of the 1980
summer can not be satisfied by the available sources. The
bringing on line of the Sanders Well Is , in my opinion, required
before the snow flies .
"Please accept this letter as the official notice provided In
paragraph 11 of the 1973 AZzreement that I have on behalf of
the DistrIct determined that the actual capacity of the
existing water sources provided by Dart are Insuff-iclent to
meet the estimated demand during the summer of 1980 and further
the magnitude of the short fall will be approximately 200 GPM
avera.ge on t1le m,.Ix:Lmuni day.
Should you have any questions regarding this matter, please
call.
Very truly yours ,

undesirable matearlal Into the, well. and to insure the public safety.
Daring Interruptions of one week or more, a sem1pen-T).anent cover
shall bv_> inst,all.c.d. For wells eased with steel, a steel co�;-er,
tack-wi lded tz) the top of the casing, is Eldequate.
14. 23 Pur-pose of DestT_-uc_tion - Proper destruction of a well that:
i.s no bc., accomplished for two Enaii.-i purposes :
A. To assure that the ground water supply is protected
a-ad pr(,-�ser-,red fo-,r.- further Use.
B. To elimInate the potential- physical hazard that exists.
1-4. 24 Definition of "Abandoned" Well. -- A well Is considered
when it has not beers used for a period of one year,
unless the owner dcclares his intention to use the well again for
SL1.;?jA.yj_r1g water or other associated purpose-. As evidence of hi-s
int-entions for conLinued use, the owner shall properly maintain
the N,\7e11. in. sash a way that:
E-82
A. The well has no defects which will facilitate the
n
xmpairinie,nt. of quali-ty of water I the ,;ell or in the water
beari-n- forniati-ons penetrated.
B . The well is covered with an approprIate locked cap.
C . The Is marl-.e(-.1 so that It can be clearly see-ri.
D. The a-rca surrounding the well is kept clear of brLISa
or debri.s .
if the pua.)p has 1-.)eeri removed j'()-r repair or replacement, the well
sl.-ial.1 -.not be considered "at-,axidoned" . provided that evidence of
repair can be shown. During t1i.e repair period, the well shall
be adequately covered to prevent injury to people and to prevent
the et-itrance of undesira.ble water or foreign matter.
Obsei--vatlon wells used In the Investi.gati-on or management of ground
water. 1.-)asi-ns by Vov e rnmental agencies or other appropriate engineering
or research organi.-nations wi-I-L not be considered "abandoned" so long
as they are maln.1-a-ined for this purpose. However, such wells s1hall
be covered wi-th an. appropriate cap, bearing the label, ""Observation
Well" ,, and the naine of the agc!i-.icy or organization, and preferably
shall be. locked when measurements are not being made.. When these
wt-Als a-re no used for this purpose or for supplying water,
tliey sh J.J- be considered "abaridoned" .
lli . 25 General- Requirement - All. "abandoned" wells shall be
destrol;;e-J-a-n such. a way that: they will not produce water or act as
a channel for. the Interchange of waters , �,-?hen such interchange N-,-ill
result In sl&n.ifica-at deterioration of the quality of water In any

B preli.m:i..r.a_-ry Work - Before the hole is filled, the well
shall be. Investigated to deLe-rune its condition, details of
con.str_ucti_on, acid Whethex- there, are obstructions that w1_11 interfere
with the process of filling and sealing.
1. If there are any obstructions , they shall be
removed if possi-ble, by cleaning out the hole or by redrilling.
2. Where necessary, t..o insure that sealing r-.iater_ial
fills not only the well casing but also any annular space o - nearby
voids , the casin :should be perforated or otherwise punctured.
3. In. drilled 'wells , it may be necessary or des:i_rabl.e
to remjve some of the casing. However, it, some.. cases' this can be
done only as the: well is f:i.1.1.e>d. In dug wells , as much of the
lini.ng s possible should be. ,_e ii.oved prioi to filling.

(per bag of to .5 to 7 gal.lons of clean water. Concrete
used sTazill be "class A" (6 sacks of Portland CefaCnt per cubic
y,-i.rd) 017 "Class B" (5 sacks p(�r cubj-c yar6) .
2. F111, Material -- Many materials are suitable for use
as a filler in des -roying wells . These include clay, silt, sand,
gravel, crushed stone, native soils , mixtures of the aforementioned
types ., and thOSE! described In the procedIng paragraph. Materi.al
containing oxj!,anic matter_ Shall not be used.
F . Tempora'--y Go-ver - DurIng periods %..,hen no work Is being
done, on. the welA l suchas overnight or while waiting for sealing
inatorial. to Set, the well and surrounding excavation, if any :, shall
be cove red. 'I'lae cover shall- be sufficiently strong and well enough
anchored to prevent the Int-roductIon of fC-rei-,-,n material into the well
and to protect tiae public f-,-or-, a potenti-ally hazardous Situation.
