DRAFT
REVISED INITIAL STUDY
Prepared Pursuant to Article V
of the
District's Environmental Guidelines
I . Project Title:
Truckee Donner Public Utility District
Water System Masterplan
This Revised Initial Study is supplemental to the Initial
Study originally distributed in November 1990. The
primary difference between the original Initial Study and
this Revised Initial Study in the addition of a thorough
discussion of 18 new potential improvements , which are
described below as items 21 through 38, and which were
added to the Draft Water System Masterplan after the
original Initial Study was prepared. The Revised Initial
Study provides the same depth of discussion of these 18
new potential improvements as it previously provided to
the original 20 potential improvements .
II . Full Description of Project:
Adoption of a Master Plan for the District' s Water System.
The Master Plan will serve as a planning tool to assist the
District in ( 1 ) identifying existing deficiencies and budgeting for
correction of such deficiencies , ( 2 ) anticipating areas where
growth is likely to occur, consistent with the Nevada County
General Plan , and identify system improvements necessary to serve
such growth , and ( 3 ) analyzing the District' s current facilities
fees and setting future facilities fees . Adoption of the Master
Plan will not, in and of itself, constitute a decision to construct
any of the 38 different potential improvements discussed, in the
Master Plan . No individual potential improvement will be
constructed without a separate decision by the District Board of
Directors. Prior to any such decision, CEQA compliance will
occur . Some of the potential improvements may never be
constructed , because the assumptions upon which their construction
is based maybe incorrect. For instance, the growth anticipated by
the Nevada County General Plan may not occur . Finally , although
the Master Plan will assist in setting future facilities fees , no
facility fee increases will occur without separate CEQA compliance.
The potential improvements are discussed in considerable detail in
the Draft Master Plan dated October, 1990, and are also listed
below:

V . Public Agencies
,List public agencies, if any, other than the District, Which must approve or give 3 permt for the
�DrojeCt,):
1 . State of California, Department of Health Services .
VI . Reason for Project:
9
The purpose of the masterplan is to identify and propose
alternatives to correct existing deficiencies within the water
system and to provide for the orderly expansion of the system.
VII . Compatibility with Zoning and Planning
(Discuss whether the project is compatible with existing toning and glans.):
The Masterplan evaluated the characteristics of each service
area of the District with respect to parcel configuration ,
topography , land use and zoning . It is compatible with
existing zoning and plans .
VIII . Environmental Settings of Project
(This description shoulo be complete enough to enable a person not familiar with tire geography of the
District to envision the environmental setting of ..he project. Any unusual features such as scenic resources,
Historic buildinos, unusual flora or fauna, or siri'ar unique qualities of the setting should be noted.):
The Masterplan identifies potential project sites which are
widely dispersed throughout the boundaries of the Truckee
Donner Public Utility District , consisting of 44 square miles .
The area is 11 miles in an east-west dimension and 4 miles
north to south.
.. In general , the area within Truckee-Donner P. U . D. can be
described as a hilly region on the eastern side of the Sierra
Nevada Mountain Range. Elevation ranges from roughly 5800
feet above sea level in the eastern portion of the District,
which contains the broad, open, fai rly level Martis Val ley, to
over 7 , 500 feet along the western edge of the District, which
extends almost to the crest of the Sierra Nevada. Slopes vary
from level on the valley floor to extremely steep ( nearly
vertical ) in some spots in the mountainous areas in the west.
Conifers such as pine and fir are common and plentiful , as
are sage brush and other shrubs. The amount of grass land is
only modest due to thin , volcanic soils and hot dry summers.
Donner Lake, a glacial lake about three miles in length and
approximately one half mile in width , is located within the
District near its western end. The Truckee River flows into
the District from the south and then turns eastward, passing
through the northern edge of the Martis Valley as it drains
towards Nevada. Interstate 80 passes through Truckee, and
serves as the major transportation link to the east and west.
A major railway parallels the freeway . State highways, two to
the south and one to the north , are also major roadways.
Washoe and Paiute Indians visited the Truckee area in the
summertime . Early immigrants passed through the area. Parts
of the Donner Party camped at the east end of Donner Lake and
also along Alder Creek north of Truckee. Many of these
historical sites have been preserved as parks or monuments and
are under control of the federal or state governments.
10
In the past, the economy of the area was supported mainly by
the railroad and timber industries, and now recreational
interests play a major role. Commercial , industrial and
institutional developments are concentrated along the
railroad/freeway corridor, while residential subdivisions are
dispersed throughout the District. The population is a m i x of
full-time local residents , second home owners and tourists .
Some of the improvements identified by the Masterplan will
likely be located at existing District facilities, which are
typically small parcels within currently developed areas .
These sites , and these areas in general , due to previous
development, have been disturbed , graded and built on , and
modification or expansion of such District facilities will not
alter the character or resources of these sites.
Other improvements will likely be located at currently
undeveloped sites . Again , the sites will typically be small
and the alteration of the site will be limited to grading to
construct a level pad for the new structure and construction
of an access driveway if necessary .
It is not possible to conduct a review of the settings of the
proposed new sites at this time because the determination that
the projects wi 11 be constructed has not yet been made and the
exact site for any particular project has not yet been
selected. Thorough descriptions will be prepared as part of
the environmental review for each project when and if the
project is undertaken .

1 . As each component of the potential projects identified
within the Masterplan are proposed for construction
complete environmental reviews will be made, based upon the
actual project sites , which have yet to be determined.
These environmental reviews may result in the filing of
exemptions , negative declarations , mitigated negative
declarations , focused environmental impact reports, or full
environmental impact reports .

ATTACHMENT A
EXPLANATION OF "YES" AND "MAYBE" ANSWERS
1-c. Construction of new tanks and other structures will involve
disruption and compaction of the soils beneath the new
facilities. New pipeline construction will involve excavation
and backfill of trenches . Any such earthwork would involve
only a small , well -defined area, and would not represent a
significant effect .
1-d. Construction of new facilities such as tanks will involve
leveling of sloped areas to create stable sites for
foundations . Again , such leveling would i nvo 1 ve on l y a sma l 1 ,
well-defined area.
1-e. Modification or destruction of unique geologic or physical
features could possibly occur , although the District is not
aware of any such features in close proximity to potential
facility sites . It is impossible to determine if such events
will occur at this time since exact construction sites have
not yet been i dent if i ed . Fac i 1 i t i es w i 11 be sited in order to
avoid disruption of any such features .
2-a. During painting of any new structures , paint fumes could be
emitted from the project site. Such emission will be of a
minor and temporary nature.
2-d . See 2-a.
3-e . New tanks will contain overflow piping that discharge into
local surface drainages . Any discharge would occur only on a
sporadic, temporary basis and will be potable water that meets
drinking water standards .
3-g . New or expanded we 1 1 s wi 1 1 withdraw groundwater f rom aquifers .
Such withdrawals could alter the existing direction or rate of
flow of groundwater in the aquifer near the well site .
Hydrogeologic data indicates that the water bearing soil
layers are deep , very thick , and have considerable areal
extent and that water is plentiful . The influence of the
we l l s w i 11 be conf i ned to a relatively small locality near the
wells and will not alter flows globally throughout the
aquifer .
3-h . New or expanded wells will withdraw water directly from the
aquifer . Even at total development of all proposed new or
expanded sources , total yearly withdrawals will be less than
half the estimated annual average net recharge of the
groundwater basin, so it is unlikely that this project will
decrease the quantity of water in the aquifer.

5-d. Wildlife habitats could be affected by construction of new
facilities in currently undeveloped sites. District
facilities are generally small , and rarely occupy any more
land than a single family residence. Any such disruption of
habitat would be of a very minor nature.
6-a. During construction , noise levels wi 11 increase due to the use
of mechanical equipment such as excavators , trucks , cranes and
small motorized devices . Such increased noise levels would
exist for only a short period , during actual construction.
9-a . New or expanded facilities could increase energy and water
use. Most increases would be only temporary, during
construction. New or expanded wells or pumping stations would
represent a permanent increase in the use of energy , although
the additional energy consumed would not be significant.
10 . New chlorination facilities will contain either gaseous or
liquid solutions of chlorine , which could be released in the
event of accident or upset. During construction , paint or
... related materials could also be released . Such risk if
accident is no greater than commonly accepted by water
utilities , and in fact is relatively slight.
11 -a. Water service could be extended to areas that currently are
not served by a public water system. Provisions of water
service in previously undeveloped areas would allow those
areas to develop and would alter the location, distribution,
density or growth rate of that area. The District would
extend water service to only those areas previously approved
for development by the County General Plan and related
planning agencies .
11-b. The Masterplan identifies both current population and the
population projected by the current Nevada County General Plan
to occur over the next 20 years . The Masterplan identifies
alternative ways to provide adequate service to existing
customers as well as how to provide adequate service to the
population that is projected to exist in' the 2010 . The
District would extend water service to only those areas
previously approved for development by the Nevada County
General Plan and related planning agencies .
16-c. The projects that could be undertaken wi 11 al 1 be water system
improvement projects . Any such projects would be undertaken
only to correct existing system deficiencies or to serve
future development that is approved by the appropriate
planning agencies .

17 . Construction and use of new chlorination equipment could
expose people to potential health hazards related to
accidental release of chlorine. Such risk of accident is no
greater than commonly accepted by water utilities, and in fact
is relatively slight.
18-a. New facilities such as tanks or buildings could potentially
obstruct views . District facilities are generally small and
would not be likely to affect views to any greater extent than
a single-family home . Since the exact sites of the new
facilities have not yet been identified , it is impossible to
determine if scenic views will be obstructed at this time.
18-c. Construction of new facilities will involve removal of trees
on forested sites and will alter the existing natural features
by clearing and leveling the original site . District
facilities are generally smal 1 , and any disruption of natural
features wou 1 d occur on a re l ati ve 1 y sma 1 i , we 1 1-def i ned area.
Since the exact sites of the new facilities have not yet been
identified, it is impossible to determine if any disrupt-Ion of
.. natural features would occur at this time.
20 . If the new construction sites contain significant
archaeological , historical , paleontological or cultural
resources , it is possible that alteration of these resources
could occur . Facilities will be sited in order to avoid
disruption of any such resources . The District is not aware
of any such resources in close proximity to potential
facilities sites . Since the exact sites of the new faci l i t i es
have not yet been i dent i f i ed , i t i s i mposs i b l e to dete rm i ne i f
such resources will be altered at this time .
