Memorandum
To: Board of Directors
From: Neil Kaufman
Date: March 1, 2007
Subject: Construction Phase Environmental Monitoring for Summer 2007
1. Why this matter is before the board:
Board authorization is required for expenditures in excess of$15,000.
2. History:
During the Winter of 2006/2007, the Board awarded two construction contracts for pipeline
replacement in the Tahoe Donner area (District Pipeline Replacement — 2007— Contract A &
District Pipeline Replacement— 2007— Contract B). The work in Contract A is covered under a
CEQA Mitigated Negative Declaration filed in 2005. The work in Contract B is categorically exempt
under CEQA.
The District is also in the process of completing the CEQA reviews for the Fibreboard Well and
Alder Drive Pump Station projects. Mitigated Negative Declarations are expected for both projects.
3. New information:
There are a number of tasks that the District must perform in order to comply with requirements of the
requirements of the State Water Resources Control Board, the Lahontan Regional Water Resources
Control Board and the Mitigation Monitoring Plans filed by the District in its CEQA Mitigated Negative
Declarations. These tasks include:
1) Monitoring and reporting on wetland restoration efforts at the Greenpoint Springs property
2) Updating the District Storm Water Pollution Prevention Plan to include planned
construction for 2007
3) On-site and on-call monitoring for raptors and cultural resources at construction sites
4) BMP training sessions for contractors hired by th District for construction projects
5) On-site inspection of District construction sites for BMP implementation and effectiveness
Inland Ecosystems has been involved in the preparation of Mitigation Monitoring Plans for both
projects and I requested that they submit a new proposal to cover the required work for the Summer
of 2007. The proposed contract price is a not to exceed amount of$28,976.00.
This total includes 16 hours of staff time for what is termed "Ad-Hoc' or"On-Call" assistance. In the
past, the District has requested that Inland Ecosystems assist the District on issues not explicitly
included in its Scope of Work. The report regarding West Reed Avenue drainage prepared at the
request of the General Manager is an example.
4. Recommendation:
I recommend that the Board approve the proposal from Inland Ecosystems for construction
phase environmental monitoring in a amount not to exceed $28,976.00.

Attachment 1. Lahontan Regional Water Quality Control Board Order
Attachment 2. Inland Ecosystems Company Brochure
The mitigation ratio for wetland impacts set by the Regional Board is 0.5:1. This
represents a total 2,613 sq. ft. of wetland the District is required to restore at Greenpoint
Springs. Inland Ecosystems proposed to complete the final year (i.e., 2007) wetlands
restoration monitoring for Greenpoint Springs. Our biologists, familiar with this project,
will carry out three surveys during the spring, summer, and fall of 2007 and determine
whether the success criteria of 100% of the initial restoration objective of 2,613 sq.ft. of
restored wetland has been achieved. We will prepare the Final Compliance Report,
including photo documentation for Board Order Resolution No. R6T-2004-0032 and
submit to the District in December 2007.
The level of effort associated with this task including three (3) one-day field surveys,
coordination with the Regional Water Quality Control Board staff, identifying any
additional restoration measures that should be taken to achieve total success (if needed),
and reporting is 56 man hours.

TASK 23 -U"r1cr Driye 120'u clip S�a tion
The following mitigation i7neasttn_�s have bem included in die CEO A Mitigated Negative
C Z�
Declaration adopted for the Alder Drive Pump Station project to avoid potential
significant effects and include:
iVitigation illleasure (]).. Pre-construction raptor and migratory nest surveys must be
conducted prior to construction activities. Inland Ecosystems proposes to conduct raptor
and migratory nest surveys 2 weeks prior to construction activities at and near the vicinity
of the Alder Drive Pump Station. If an active nest of a special status species is located,
Inland Ecosystems will consult with the District and the California Department of Fish
and Game as to appropriate measures to minimize potential impacts. Inland Ecosystems
estimates the level of effort associated with this component of the mitigation monitoring
at I day of field work- and a half-day (4 lirs) report preparation. The report on the raptor
and migratory nest surveys shall be provided to the District as part of the CEQA
Mitigation Monitoring and Reporting Program for the project.
Mitigation Measure (2): During the initial excavation and soil disturbance at the site e
tu th
District must have a field monitor on-site. Inland Ecosystems proposes to carry out the
monitoring and reporting. In the event that evidence of cultural resources is encountered
during initial site disturbance, a Registered Professional Archeologist would be notified
to gather information on such resources and coordinate any findings with the appropriate
state, federal, and tribal entities according to standard reporting procedures. Inland
Ecosystems estimates the level of effort associated with this task at 5 full construction
days or 40 hours. A half-day (4 hrs) is estimated to prepare a report to the District as part
of the CEQA Mitigation Monitoring and Reporting Program for the project.

TASK 2.5 Best Management Practices (BMP) and Erosion Control Training
Inland Ecosystems proposes to prepare and present two (2) BMP and Erosion Control
Training Courses for District staff and contractors and update the existing Power Point
presentation. We will also coordinate the training course with staff from the Lahontan
Regional Water Quality Control Board. This will be the third year the District has carried
out these important training courses and Regional Board staff(Scott Ferguson in 2005
and Robert Erlich in 2006) have provided a presentation that outlined their
responsibilities to protect water quality and the consequences for violation of state law.
Our goal is to ensure that the District is provided with an exceptionally high quality of
BMP training to ensure that construction projects are carried out with the least amount of
environmental disturbance. Inland Ecosystems estimates the level of effort associated
with this task at 16 hours.
TASK 2.6 Best Management Practices (BMP) and Erosion Control Inspections
Inland Ecosystems proposes to conduct weekly Best Management Practices and erosion
control inspections and reporting according to the District's SWPPP. Inspections and
follow up reporting would be carried out every week between May 1 and October 15,
2007. The total number of inspections is expected to be 24. Inland Ecosystems estimates
that each inspection would require 4 hrs field time and 1 hr reporting for a total of 120
hours.
TASK 2.7: Ad Hoc Assistance (Optional)
Inland Ecosystems proposes to set aside 16 man hours to address unanticipated District
needs that may arise during the 2007 construction season and are not included as part of
the above tasks.

CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD
LAHONTAN REGION
RESOLUTION R6T-2004-0032
TRUCKEE DONNER PUBLIC UTILITY DISTRICT
DONNER LAKE WATER SYSTEM IMPROVEMENTS, PHASE 2 -
EXEMPTION TO WASTE DISCHARGE PROHIBITION CONTAINED IN THE
WATER QUALITY CONTROL PLAN FOR THE LAHONTAN REGION
Nevada County
WHEREAS, the California Regional Water Quality Control Board, Lahontan Region
finds:
1. On June 23, 2004, the Truckee Donner Public Utility District (District) submitted
a complete Application for Clean Water Act Section 401 Water Quality
Certification to the Regional Water Quality Control Board, Lahontan Region
(Regional Board) for the Donner Lake Water System Improvements, Phase 2
Project (hereinafter referred to as the "Project"). The purpose of the Project is to
replace/upgrade existing water system components to provide Donner Lake
residents with an improved and reliable water supply and supplemental fire flow
protection. The Project is the final phase of an overall system upgrade of the
Donner Lake Water System that began in 2001.
2. The Project involves multiple components and locations surrounding Donner
Lake, which is located west of Downtown Truckee, in Nevada and Placer
Counties. The Project components include:
Red Mountain Tank Site and Pipeline Rehabilitation
Robin Lane to Denton Avenue Pipeline Installation
• Donner Avenue Pipeline Rehabilitation
• Robin Lane to Olympic Drive Pipeline Installation
• Cedar Point Pipeline Installation
• Greenpoint Springs Mitigation Site
All Project components except for the Red Mountain Tank Site are located on the
north side of the Donner Lake Basin between Olympic Drive to the east, Donner
Pass Road to the south, Donner Lake Road to the west, and Interstate 80 to the
north. The Red Mountain Tank Site is located on the south side of the Donner
Lake Basin between Mount Judah Drive and Devil's Peak Road, south of South
Shore Drive. The Project component locations are shown in Attachment"A",
which is made a part of this Resolution.
-3- RESOLUTION NO. R6T-2004-0032
six locations in order to install service laterals. The six point excavations will
disturb approximately 10 square feet each, for a total temporary wetland
disturbance of 60 square feet. Trench depth will average five feet deep resulting in
approximately 25 cubic yards of excavation. The temporarily disturbed wetland
habitat will be fully restored using the same techniques as being used at the Red
Mountain Tank site.
Robin Lane to Olvrnpic Drive Pipeline Installation
This project component involves installing 1,500 feet of 8-inch and 12-inch
diameter pipe through an undeveloped area between the eastern end of Robin
Lane and Olympic Drive above Donner Pass Road. The construction corridor will
be 15 feet wide and will traverse across a small (one to two feet wide), lightly
vegetated, unnamed drainage channel that conveys storm water runoff and
seepage-spring water originating from above Interstate 80. Trenching activity will
temporarily impact approximately 40 square feet of the drainage channel. Trench
depth will average five feet deep resulting in approximately three cubic yards of
excavation. The affected drainage channel area will be fully restored.
Cedar Point Pipeline Installation
This project component involves installing approximately 2,400 feet of 1.2-inch
diameter pipe. The pipeline alignment will begin at the intersection of Denton
Avenue and Pioneer Drive and proceed down an existing dirt access road through
the District's Greenpoint Springs property, and then through an undeveloped area
ending at the intersection of Donner Lake Road and Cedar Point Drive. This
component does not have any wetland habitat or other surface water impacts.
Greenpoint Springs Mitigation Site
All temporarily disturbed surface water features (5,227 square feet wetland
habitat and ephemeral drainage)will be fully restored (1:1 restoration credit). The
District is also required to mitigate for temporal losses of wetland habitat function
by developing 2,613 square feet of wetland habitat (0.5:1 mitigation credit). The
off-site wetland mitigation will be located at the District's Greenpoint Springs
property.
The District's Greenpoint Springs property historically consisted of a diverse,
high-quality seep-spring/wetland/riparian habitat complex that is located on the
north side of the Donner Lake Basin between Interstate 80 and Donner Pass Road.
Portions of this habitat have been altered/dewatered by spring boxes that divert
flows into two water supply tanks and by an access road system. The District will
create approximately 8,712 square feet of wetland habitat by decommissioning an
upper access road. This amount of wetland mitigation substantially exceeds the
Regional Board's 0.5:1 off-site mitigation ratio requirement.
x ,
-5- RESOLUTION NO. R6T-2004-0032
above-referenced system improvements will provide a reliable water
system and adequate fire suppression supply for the Donner Lake area.
Therefore, the proposed Project components are necessary for public
health and safety(reliable water supply and fire flow protection) and to
provide an essential public service (water supply and fire protection).
b. There is no reasonable alternative to locating the project or portions of
theproject within the 100-yearflood plain.
The District and its consultant conducted an extensive alternatives analysis
that assess multiple system designs and infrastructure locations and
routing. The Project minimizes 100-year flood plain impacts by selecting
routes that cross unavoidable wetland habitat and the ephemeral drainage
channel at the narrowest locations, using pipeline rehabilitation techniques
that minimize trenching (slip-lining), and using water system technologies
that increased the District's options for locating/relocating infrastructure.
Other alternative designs that would have further reduced the extent of
100-year flood plain encroachment were deemed infeasible due to existing
water system constraints, the lack of access/room to locate new
infrastructure due to existing multiple utilities, and/or impacts to other
valuable natural resources. There is no other reasonable alternative to
locating the Project or portions of the Project outside the 100-year flood
plain.
C. The project, by its very nature, must be located within the 100-year
floodplain.
The Red Mountain Tank/Pipeline Installation Project component involves
in part replacing a pipeline that is located within a broad wetland habitat
area within the same alignment. Replacing the pipeline within the same
alignment by its very nature must occur within wetland habitat/100-year
flood plain and is also necessary given existing system design.
The Robin Lane/Denton Avenue, Donner Avenue, and Robin
Lane/Olympic Drive Project components cross either wetland habitat or an
ephemeral drainage channel that generally flow down-slope across the
northern side of the Donner Lake Basin. Given the linear nature of the
project, the location of existing homes that must be served, and the pattern
of wetland/100-year flood plain habitat, it is necessary to located limited
Project elements within wetland/I 00-year flood plain habitat.
d. The project incorporates measures, which will ensure that any erosion
and surface water runoffproblems caused by the project are mitigated to
levels of insignificance.
-7- RESOLUTION NO. R6T-2004-0032
7. The Regional Board has notified the District and interested agencies and persons
of its intent to adopt this Resolution.
8. The Regional Board, in a public meeting, heard and considered all comments and
determined that the Project satisfies the exemption criteria stated above.
THEREFORE, BE IT RESOLVED THAT:
l. The criteria established for exemptions to the Basin Plan prohibition stated in Finding
No. 5 above are satisfied for the Donner Lake Water System Improvements, Phase 2
Project.
2. The Regional Board hereby grants an exemption to the Basin Plan prohibition stated
in Finding No. 4 for the Donner Lake Water System Improvements, Phase 2 Project.
I, Harold J. Singer, Executive Officer, do hereby certify that the foregoing is a full, true,
and correct copy of a Resolution adopted by the California Regional Water Quality
Control Board, Lahontan Region, on July 27, 2004.
