COMMENTS ON THE 2012 DRAFT ENVIRONMENTAL IMPACT REPORT FOR THE
PROPOSED CANYON SPRINGS SUBDIVISION PROJECT (PROJECT)
(SCH# 2004052060), TOWN OF TRUCKEE, NEVADA COUNTY
The Lahontan Regional Water Quality Control Board (Water Board) staff received a
copy of the Draft Environmental Impact Report (DEIR) for the above - referenced project
on December 21, 2012. The proposed Project presented in the current DEIR reflects
revisions to previously proposed developments involving the Project. The Project will be
located at the far eastern end of the Town of Truckee on currently undeveloped land.
We have reviewed the DEIR and our comments follow.
1. Section 4.6 Geology, Soils and Seismicity: E. Impacts and Mitigation
Measures, Impact and Mitigation Measure GEO -3, Page 4.6 -22 - During
grading and earthwork on the project site soil erosion and the loss of topsoil
may occur. This Section of the DEIR does not identify or discuss the Water
Board permitting requirements in regard to soil stabilization for construction
projects with over an acre of soil disturbance (although the same permitting
requirements are discussed in Section 4.9 (page 4.9 -5) in regard to hydrology
and water quality). The Water Board will require the project proponent to
procure a Statewide General Stormwater Construction Permit, and provide a
Stormwater Pollution Prevention Plan for the proposed Project that
adequately addresses Best Management Practices and soil stabilization
implementation.
2. Section 4.9 Hydrology and Water Quality: B.2.b. State Laws and Regulations,
Water Quality Control Plan for the Lahontan Region (Basin Plan), Paragraph
2, last sentence, states "However, exemptions may be granted by the
Lahontan RWQCB that fall within the following categories of new projects."
Page 4.9 -4 —This statement regarding discharges due to disturbance to 100 -
year floodplains fails to address that the Project categories allowed must also
meet certain requirements; in addition, findings must be made pursuant to the
Basin Plan prior to exemptions being granted. However, we note that no
disturbance is proposed within any 100 -year floodplain.

3. Section 4.9 Hydrology and Water Quality: B.a.i. Total Maximum Daily Load
(TMDL) — Page 4.9 -3. The DEIR notes that primary sources of sediment to
the Clean Water Act Section 303(d) listed Middle Truckee River include dirt
roads, urban stormwater runoff, legacy erosion sites, and graded ski runs.
The Project site as described has a legacy of disturbance. The Town of
Truckee is required to meet waste load allocations of sediment from
urbanized sources as specified by the TMDL. We request additional
information regarding how the Project will implement stabilization of sediment
within the categories noted above, which will provide the Town of Truckee
with the ability to meet a portion of the waste load allocations of the TMDL
and comply with the monitoring and reporting associated with the Small
Municipal Storm Sewer System (MS4) permit.
