RE: Comments on Canyon Springs Limited Revised Draft Environmental Impact Report
Dear Ms. Nishimori:
The Tahoe - Truckee Sanitation Agency (T -TSA) has received the Notice of Availability (NOA)
you sent us for the Proposed Canyon Springs Subdivision Project (Project). T -TSA staff have
reviewed these materials and offers the following comments
T -TSA provides regional wastewater treatment service to the properties that lie within the
Agency's five member sewage collection districts - the North Tahoe Public Utility District, the
Tahoe City Public Utility District, the Alpine Springs County Water District. the Squaw Valley
Public Service District, and the Truckee Sanitary District (TSD). T -TSA also serves Northstar by
way of an agreement between TSD and the Northstar Community Services District. T -TSA
owns, operates and maintains the Truckee River Interceptor (TRI), a main trunk line for raw
sewage conveyance, and the Tahoe - Truckee Sanitation Aj=ency Water Reclamation Plant (WRP),
both of which are described in more detail below.
The 17 -mile long TRI pipeline runs along the Truckee River corridor between Tahoe City and
the WRP in Truckee. The interceptor flows exclusively by gravity and varies in size from 24- to
42- inches in diameter. The interceptor conveys all of the untreated, raw sewage collected from
the northern and western shores of Lake Tahoe. Alpine Meadows, Squaw Valley, Truckee, and
Northstar.
The WRP regional facility is designed to treat and dispose of the sewage delivered by the TRI.
Through a series of biological, chemical and physical processes, the wastewater is purified to a
degree where surface and ground water quality is protected. Wastewater flow to the facility
varies in quantity and quality in proportion to the population present during the year. The WRP
is principally sized to treat the maximum sewage flows that occur during peak holiday periods
with the large influx of seasonal residents and visitors.

We would like to take this opportunity to offer the following comments on the documents you've
made available for review:
As part of the environmental review phase, there will be a need to assess the potential
impacts on the sewage conveyance and treatment infrastructure that would serve the
proposed Project. This Project would result in an increase in the amount of wastewater
that would require conveyance through the TRI and treatment at the WRP. More detail
will need to be furnished on the proposed improvements before T -TSA can make a
proper assessment as to what impact the Project may have on our facilities. In order to
accurately evaluate whether or not the TRI and WRP have sufficient unused capacities to
serve the proposed Project, estimated Project wastewater flows must be provided to
T -TSA. Project developers will need to present development plans with tabulated fixture
unit counts and other T -TSA billing factor counts. The methodology used to develop
these fixtures, factors, and flowrates also must be submitted.
2. Please be advised at this early stage in the planning process that T -TSA does not issue
Will Serve letters. All capacity allocations are made on a first -come, first -serve basis for
all projects within T -TSA's service area.
Potential impacts to TSD's wastewater collection facilities should also be evaluated. Project
planners should contact and coordinate with TSD separately from T -TSA in evaluating the
impacts of this Project to their systems.
T -TSA would like to thank the Town of Truckee for the opportunity to provide these comments.
Please evaluate and address the concerns noted above so that we can better define the impacts
that this Project might have on T -TSA's facilities and operations.
If you have any questions, please do not hesitate to call me at (530) 587 -2525
Sincerely,
Jason A. Parker
