1.0 INTRODUCTION
1.1 INTRODUCTION AND REGULATORY GUIDANCE
This Initial Study (IS) has been prepared to comply with the California Environmental
Quality Act (CEQA) and addresses the environmental impacts of constructing the
Truckee Donner Public Utility District's (District) New Sierra Meadows Pump Station.
The IS has been prepared in accordance with CEQA, Public Resources Code 21000 et
seq., and the State CEQA Guidelines, Title 14 California Code of Regulations (CCR)
15000 et sq. An IS is prepared by a lead agency to determine if a project may have a
significant effect on the environment. The lead agency for the proposed project is the
Truckee Donner Public Utility District.
1.2 PURPOSE
The purpose of the project is to replace an existing pump station facility that is in poor
condition. The new Sierra Meadows pump station will also include an emergency
generator and will improve the service reliability to the District's customers. This IS
addresses the environmental impacts of constructing the new pump station.
1.3 SUMMARY OF FINDINGS
Section 3 of this IS contains the Environmental Checklist that identifies potential
environmental impacts (presented by environmental subject area) and a discussion of
each impact that would result from implementation of the proposed project. Based on the
Environmental Checklist and the supporting environmental analysis provided in this
document, development of the proposed project would result in the following impacts:
• No Impact: agricultural resources, hydrology and water quality, geology and
soils, land use and planning, mineral resources, population, public services,
utilities and service systems, hazards and hazardous materials,
traffic/transportation, and recreation.
• Less-than-Significant Impacts: aesthetics, air quality, and noise.
• Less-than-Significant Impacts with Mitigation Incorporated: biological
resources and cultural resources.
In accordance with State CEQA Guidelines 15070, a Mitigated Negative Declaration may
be prepared if the proposed project will not have a significant effect on the environment
after the inclusion of mitigation measures into the project. There is no substantial
evidence that the proposed project, as revised by mitigation measures, would have a
significant effect on the environment based on the available project information and the
environmental analysis presented in this document. Therefore, a Mitigated Negative
Declaration is proposed to be adopted in accordance with CEQA and State CEQA
Guidelines.

2.0 PROJECT DESCRIPTION
2.1 PROJECT LOCATION
The proposed project site is located on the USGS 7.5-minute Truckee quadrangle within
the southeastern portion of the Town of Truckee, Nevada County, California (Figure 1).
The new pump station will be located at the northern end of Pine Cone Road and
Tamarack Way on an easement granted to the District by a private property owner. The
project site occurs at an elevation of approximately 6,100 feet adjacent to residential
homes and roadways.
2.2 PROJECT SETTING
The Town of Truckee is situated on the east slope of the Sierra Nevada Mountains at the
base of Donner Summit. The Truckee area is surrounded by mountainous terrain and is
heavily treed with various species of native pines. The proposed pump station is directly
adjacent to and bounded by Pine Cone Way, Tamarack Way, and residential homes.
2.3 PROJECT CONSTRUCTION
The District proposes to construct an 18-foot by 24-foot booster pump station with
concrete block walls, wooden frame roof, and asphalt composition shingles. A site plan is
provided as Figure 2. Construction will involve grading, excavating, and trenching.
Runoff from the site will be directed to an underground infiltration gallery designed to
contain a 20-year, 1-hour storm event. There will be no adverse hydrologic changes to
existing drainage conveyances.
As is standard with all District construction projects, permanent erosion control measures
and Best Management Practices will be implemented. The District has updated its Storm
Water Pollution Prevention (SWPPP) under the State Water Resources Control Board,
National Pollutant Discharge Elimination System, General Construction Permit to include
this project.
2.4 ALTERNATIVES TO THE PROPOSED PROJECT
The "No Project" alternative does not offer any advantages over the proposed project in
terms of improving service reliability to District customers. Therefore, the proposed
project is considered the preferred alternative.

d) Expose sensitive receptors to ❑ ❑ ❑ H:
substantial pollutant concentrations?
e) Create objectionable odors affecting ❑ ❑
a substantial number of people?
Response to questions:
(a): The project would not conflict with or obstruct implementation of an applicable air
quality plan and, therefore, there would be no impact.
(b): Construction activities have the potential to generate emissions through the release of
fugitive dust and equipment exhaust associated with construction and excavation
activities. Fugitive dust emissions shall be minimized at all times utilizing control
measures including regularly applied water. When transporting material during
construction, measures shall be taken to prevent material from spilling or blowing onto
roadways. Therefore, this impact is considered less than significant.
(c)-(e): Due to the short-term nature of the project, air emissions would not be considered
cumulatively considerable. The project would not create objectionable odors affecting a
substantial number of people and, therefore, there would be no impact.

Truckee Donner Public Utility District 9 April 2005
Response to questions:
Surveys for special status wildlife species were conducted on March 15, 2005 by Mark Chainey
Wildlife Consulting and Inland Ecosystems. A search of the California Natural Diversity
Database (CDFG 2005) was conducted for all records of special status plant and animal species
occurring within the USGS quadrangle location encompassing the project, as well as all adjacent
quadrangles. A species list was requested from the U.S. Fish and Wildlife Service (USFWS) for
the Norden and Truckee quadrangles (Appendix A). A target list of special-status wildlife
potentially occurring in the project area is contained in Appendix B. Appendix C is a target list
of special-status plants potentially occurring in the project area.
An understanding of the habitat requirements for species potentially utilizing the site and the
degree of existing human development in the immediate area were factors considered in the
impact assessment.
(a): No special status species were found during survey work, nor is there habitat present for
any listed animal or plant species. The proposed booster pump station is located on
private property adjacent to Pine Cone Way, Tamarack Way, and residential homes (with
dogs), which strongly precludes any significant use of the site by wildlife. The proposed
project will not have a significant impact on rare, endangered, threatened, or other
special-status species identified in Local or regional plans, policies, or regulations or by
CDFG or USFWS.
Numerous raptor species do, however, forage and nest in various habitats throughout the
Sierra Nevada throughout spring and summer. Raptor nests are protected under the
Migratory Bird Treaty Act (MBTA) and by Section 3503.5 of the California Fish and
Game Code. Disturbance to an active raptor nest could occur during construction
activities. Disturbing an active raptor nest would violate Sections 3503 and 3503.5 of the
Department of Fish and Game Code and would be considered a potentially significant
impact. The nests of all migratory birds are also protected under the MBTA, which makes
it illegal to destroy any active migratory bird nest. Implementation of the mitigation
measure outlined below will reduce potential impacts to special-status species and/or
their habitats to a less than significant level.
(b)-(c):No wetlands or waters of the U.S. were found in the project area. The project would not
have a substantial adverse effect on any sensitive habitat identified in local or regional
plans, policies or regulations, or by CDFG or USFWS.
(d): The proposed booster pump station is located in a residential area. Construction activities
will not interfere substantially with the movement of any native resident or migratory
wildlife species or with established native resident or migratory wildlife corridors.
Implementation of the mitigation measure outlined below will reduce potential impacts to
special-status species to a less than significant level.
Truckee Donner Public Utility District IO April 2005
(e): Some trees will need to be removed to accommodate the booster pump station.
Implementation of the mitigation measures outlined below would reduce this impact to a
less than significant level.
(f): The project will not conflict with local policies protecting biological resources or conflict
with the provisions of an HCP, NCCP, or other approved conservation plan and,
therefore, there would be no impact.
Mitigation Measure(s) - The following mitigation measures shall be incorporated into the
project:
4(a);(d):Raptor and migratory nest surveys will be conducted within and adjacent to the project
site prior to construction activities. If an active nest is located in close proximity to the
project site, the District will immediately consult with the California Department of Fish
and Game.
4(e): Any mature tree over 12" diameter that may need to be removed will be mitigated by on-
site planting of 5-gallon native trees at a 2:1 ratio.

Truckee Donner Public Utility District I l April 2005
Response to questions:
The cultural resources responses are based on a Records Search conducted by the North Central
Information Center of the California Historical Resources Information System (See Appendix
D). California law recognizes the need to protect Native American human burials, skeletal
remains, and items associated with Native American burials from vandalism and inadvertent
destruction. The Native American Heritage Commission (NAHC) was contacted for information
about Sacred Lands within the project area. The NAHC did not identify any Sacred Lands within
the project area and provided references of local Native American groups and individuals to
request additional information (Appendix D). Both the Washoe Tribe of Nevada and California
and the Archives and Cultural Center were contacted for any further information and no
responses were received.
(a)-(d):The archaeological record search conducted at the North Central Information Center of
the California Historical Resources Information System (NCIC File No. NEV-05-11)
indicated that there are no cultural resources located within the project area. While there
are no known archeological resources at the proposed project site, it would be a
significant impact if such resources were present, and were displaced or demolished
during construction activities. Implementation of the mitigation measures outlined below
will reduce this potential impact to a less than significant level.
Mitigation Measure(s) - The following mitigation measures shall be incorporated into the
project:
(a)-(d):The District will have Dr. Susan Lindstrom, a Local Truckee cultural/historic archeologist,
on-call during any site disturbance. In the event that evidence of cultural resources is
encountered during construction of the booster pump station, Dr. Lindstrom would be
notified to record the location of such resources and gather available information. The
District will coordinate any findings with the appropriate state, federal, and tribal entities
according to standard reporting procedures to avoid disruption of any archaeological and
historical resources.

Response to questions:
(a)-(c): The project site is not located within any fault zone of the Alquist-Priolo Earthquake
Faulting Zoning Map. The project is limited to construction of the booster pump station
that would be designed in accordance with the California Health and Safety Code. This
code requires that structures be designed to resist stresses developed by earthquakes. The
booster pump station would be designed in accordance with the standards in the Uniform
Building Code. There is no aspect of the project that would expose people or property to
increased risk during strong seismic ground shaking, ground failure, or liquefaction.
Other hazards, such as lateral spreading, lurch cracking, regional subsidence and
liquefaction, are unlikely to occur during project construction and, therefore, there would
be no impact.
(d);(f): Construction of the booster pump station would not expose people or structures to
potential adverse effects from landslides nor would it be located on unstable soils and,
therefore, there would be no impact.

development of a Storm Water Pollution Prevention Plan (SWPPP). The District's
SWPPP includes mitigation measures for the protection of water quality. The estimated
surface area of soil disturbance to install the booster pump station is 500 square feet. All
stormwater runoff from impervious surfaces will be directed to an infiltration gallery
designed to accommodate a 20-year, I-hour storm event. A preliminary list of specific
BMPs for this project is provided in Appendix E. There are no water demands associated
with the project, nor will the project impact groundwater quality or quantity. The project
would not change absorption rates, drainage patterns, or the rate and amount of surface
runoff. No housing is proposed as part of this project and no portion of the project area is
subject to the possibility of seiche,tsunami, or mudflow. Therefore, there are no impacts.

I) For a project within the vicinity of ❑ ❑ ❑
a private airstrip, would the project
expose people residing or working
in the project area to excessive noise
levels?
Response to questions:
(a);(e): There will be no impact to these issues related to noise as a result of the proposed project.
(b);(d):During construction activities, noise levels would increase temporarily during
construction activity but would not result in a substantial increase above levels existing
without the project. This noise increase would be of short duration, and would occur
during the daylight hours of 7 a.m. - 6 p.m. Monday-Friday, and 8 am. - 6 p.m. on
Saturday. Construction plans shall include reference to these restricted hours of
construction. This impact would be restricted to the construction period and is considered
less than significant.
(e)—(f):The Project site is not within an airport land use plan or private airstrip and, therefore,
there would be no impact.

Does the project have the potential to ❑ ® ❑ Eldegrade the quality of the environment,
substantially reduce the habitat of a fish
or wildlife species, cause a fish or
wildlife population to drop below self-
sustaining levels, threaten to eliminate
a plant or animal community, reduce

rare or endangered plan or animal or
eliminate important examples of the
major periods of California history or
prehistory?
Does the project have impacts that are ❑ ❑

incremental effects of a project are
considerable when viewed in
connection with the effects of past
projects, the effects of other current

Does the project have environment ❑ ❑
effects which will cause substantial
adverse effects on human beings, either
directly or indirectly?
Truckee Donner Public Utility District 27 April 2005
Response to questions:
(a): With implementation of the recommended mitigation measures, the project does not have the
potential to degrade the quality of the environment, reduce the habitat of any wildlife species nor
create adverse effects on human beings. The proposed project is comprised of standard construction
activities to install a booster pump station. The project will not adversely affect any special status
species identified in local or regional plans, policies or regulations, or by the California Department
of Fish and Game or the United States Fish and Wildlife Service.
(b): The proposed project would not result in any cumulative impacts or irreversible environmental
damage because of the relatively small scale of the project and, therefore, this impact is considered
less than significant.
(c): The project does not have environment effects that will cause substantial adverse effects on
human beings and, therefore, there is no impact.

Re: Cultural Resources Record Search
Dear CDs. Pilas-Tredway,
Inland Ecosystems is providing cultural resources consulting services to the Truckee
Donner Public Utility District (Districtt The District's project entails installing a new
booster pump station at the northern end of Pine Cone Road and Tamarack Way on an
easement granted to the District by a private property owner. The project site falls within
the Truckee 7.5-minute USCrS quadrangle in Nevada County (see attached map). The
Township/Range/Section information is as follows_
Sierra Meadows Pump Station: TI7NIRI6EISec22
I am inquiring about any Sacred Lands you are aware of in the project area. if it does not
appear that any Sacred Lands are present, release provide us with a list of local contacts
that may have further information about the project area. If you have any questions,
please contact me at (530) 847-5913. Please fax results to (715) 786-3229. Thank you for
your time and effort_

Re: Cultural Resources Record Search
Dear Mr, Dancing Feather:
Inland Ecosystems is providing cultural resources consulting services to the Truckee
Donner Public Utilities District. The project entails replacing 380 feet of existing pipe
and installing a new water tank and access road at one location along Interstate 80,
installing a new booster station at two other locations in existing road rights-of-way. The
area falls on the Truckee and Norden 7.5 minute USGS quadrangles in Nevada County
(see attached maps), For the project areas the Township/Range/Section info follows:
Storage tank/road/pipe: T17N/R15E/Sec24
Sierra Meadows Pump Station: T17N/R16E/Sec22
Red Mountain Pump Station: T17N/R15E/Sec14
I am inquiring about any Sacred Lands you are aware of in the project areas that could be
affected. If you have any questions, concerns, or comments about the proposed project,
please feel free to contact me on my cell phone at(510) 847-5913.

APPENDIX E
PRELIMINARY BMPs FOR PROJECT CONSTRUCTION
The District's BMP Plan includes the following measures:
• The District will implement an effective combination of erosion and sediment
control on all disturbed areas at this project site. The District will follow the
guidelines established for erosion control methods consistent with the
requirements of the LRWQCB Lahontan Region Guidelines for Erosion Control.
These erosion control practices will be implemented to include, but not limited to,
silt fencing placed downslope of the project site to minimize sediment transport
off-site.
• Construction will involve grading a level pad for the booster pump station and
trenching. All stormwater runoff from impervious surfaces will be directed to an
infiltration gallery, designed to contain a 20-year. I-hour storm event. There will
be no adverse hydrologic changes to existing drainage conveyances. All
excavated material not used for backfill will be disposed of in landfills. The
District will ensure that all spoil piles are stabilized and covered with heavy-duty
plastic sheeting during any precipitation event and/or overnight.
• Construction will be temporarily suspended prior to and during storm events. For
the purpose of this project, a "storm" is defined as any precipitation event that
could or would cause runoff, and sedimentation from surfaces exposed by
construction. Construction activities also have the potential to release fugitive
dust associated with excavation activities and grading. In order to reduce this
potential impact fugitive dust emissions shall be minimized at all times utilizing
control measures including aggressive sweeping program and regularly applied
water when deemed necessary. When transporting material during site preparation
or construction, measures shall be used to prevent material from spilling or
blowing onto roadways.
• Where soil disturbance has occurred in undisturbed areas, the District will
implement measures such as covering with mulch, fiber rolls or blankets, silt
fencing, hay bales, and/or reseeding to protect soil particles from transport by
rainfall or wind. Staging areas will be delineated with construction and silt
fencing. There will be no physical changes to roadways as a result of the project.
• Specific BMP's for spill prevention include the contractor having on-site, at all
times, a Spill Containment Kit. All equipment will be properly cleaned and
inspected for leaks prior to and during trenching operations. All equipment will be
checked regularly, at a minimum of once in the morning and once in the
afternoon, for leaks before and during operation.
• Both the contractor as well as the District will ensure that all BMPs implemented
for this project are effectively maintained. The District will conduct inspections of
the construction site on a daily basis and more frequently prior to anticipated
storm events and after actual storm events. Equipment, materials, and workers
will be available for rapid response to failures and emergencies. i
