Holzmeitter , General Manager 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.

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 . IX .

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. 20 Page Two - Attachment A 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 . 21 Page Three — Attachment A 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 . 22
