WASTE DISCHARGE REQUIREMENTS
FOR
SOUTH TAHOE PUBLIC UTILITY DISTRICT CONSTRUCTION OF
FALLEN LEAF LAKE COLLECTION SYSTEM IMPROVEMENTS
El Dorado County
The California Regional Water Quality Control Board, LahontanRegion, finds:
1. A completed Report of Waste Discharge for the
Construction of Fallen Leat Lake Collection systemImprovementswassubmittedbySouthTahoePublic
Utility District on March 15, 1990. Construction willtakeplaceatvariouslocationsthroughoutthe
southwest section of the existing sewage collection ' system. The southwest section of the collection systemextendsfromtheStanfordSierraCamptothemain
export station near the Fallen Leaf Lake Lodge. The
lands are either owned by or covered by easement toSouthTahoePublicUtilityDistrict. For purposes ofthisOrder, South Tahoe Public Utility District isreferredtoasthe "Discharger" and the Construction oftheFallenLeafLakeCollectionSystemImprovementsasthe "project".
2. The South Tahoe Public Utility District submitted the
Fallen Leaf Lake Sewer Collection System FacilitiesStudy - Final Report on November 3, 1989. The report
describes the modifications to be made to the southwest
section of the system. It also discusses some future
modifications that may be made to the eastern section
of the collection system, if necessary.
3. Proposed construction activities include replacing andmodifyingequipmentatejectorstationsESl, ES2 and
ES3, modifying the vacuum system at vacuum stationsVS1, VS2 and VS3, converting the existing vacuum
pipeline to a low pressure pipeline and adding air
relief valves to the pipeline, installing new storage
facilities and auxiliary power facilities. New
telemetry equipment, wastewater flow meters and
temporary spill containment facilities will also beinstalled.
4. This project is being constructed to satisfy the
requirements of Cease and Desist Order No. 6-89-95,
which was adopted by this Board on April 13, 1989 to
improve the reliability of the collection system.

5. Potential pollutant discharges from the project include
products of erosion, construction waste materials,
small amounts of oil and grease from construction
equipment, and domestic sewage from spills.
6. The above construction is located along the perimeter
of Fallen Leaf Lake Road in the S/2 of Section 14,
T.12.N, R.17.E, MDB&M as shown on Attachment "A" which
is made a part of this Order. Attachment "B", which is
made a part of this Order, provides a more detailed map
of the project area.
7. The land on which the project is to be sited is
classified as Land Capability Classes la and 1c. Class
la and Class lc lands are described as lands having a
high erosion hazard potential. Lands of these
capability classifications are allowed no more than 1
percent coverage. The proposed project will result in
135 square feet of additional coverage in Class lc
lands. The additional coverage will exceed the
allowable 1 percent coverage by 110 square feet.
8. The following prohibition is specified in Chapter IV of
the Lake Tahoe Basin Water Quality Plan, as amended:
The discharge or threatened discharge, attributable to
new development in stream environment zones or which is
not in accordance with land capability, of solid or
liquid waste, including soil, silt, sand, clay, or
other organic or earthen material, to ground or surface
waters in the Lake Tahoe Basin is prohibited."
9. The Lake Tahoe Basin Water Quality Plan prohibition
refers to new development which is "not in accordance
with land capability." The term "not in accordance
with land capability" refers to new development which
will result in impervious coverage in excess of the
allowable,percentage of impervious coverage.
10. Chapter IV of the Lake Tahoe Basin Water Quality Plan,
as amended, contains the following exemption criteria
for the prohibition stated in Finding No. 8:
The prohibition shall not apply to any structure the
Regional Board . approves as reasonably necessary
for health and safety.
Approval of exemptions shall include the findings set
forth in Section 20.4 of the Tahoe Regional Planning

11. In order to approve the development as "reasonablynecessaryforhealthandsafety", the Regional Board
must make the following findings that are specified in
Chapter V of the Lake Tahoe Basin Water Quality Plan asamended:
a. The project is necessary to protect public health
or safety.
b. There is no reasonable alternative which avoids
the need for an exemption.
c. The project incorporates measures which will
ensure that any erosion and surface runoff
problems caused by the project are kept to a
minimum.
d. Except where mitigation measures are infeasible
because the financial resources of the party
proposing the project are severely limited, any
encroachment of stream environment zones is
mitigated by restoration of presently disturbed
areas in the Basin sufficient to offset the effectoftheproject.
12. The project is necessary to prevent raw sewage frombeingdischargedtoFallenLoafLakeandthelands
surrounding Fallen Leaf Lake which will in turn improve
health and safety by preventing public contact with raw
sewage.
13. Based upon the Final Negative Declaration, there is no
reasonable alternative which avoids the extent of over -
coverage on Class lc lands.
14. South Tahoe Public Utility District has proposed
specific measures within the Final Negative Declaration
that will prevent erosion and stormwater runoff
problems from occurring.
15. The project does not encroach upon any stream
environment zones: and therefore, mitigation for such
encroachment is not required.
16. Section 20.4 of the TBPA Code of ordinances permits
land coverage in Class la, lc, 2 and 3 lands if the
following findings are made:
a. The project is necessary for public health, safety

b. There is no reasonable alternative, including
relocation, which avoids or reduces the extent of
encroachment in Land Capability Districts la, lc,
2 and 3.
c. The impacts of the coverage and disturbance are
fully mitigated in the manner prescribed by
Subparagraph 20.4.A(2)(e).
17. Findings No. 12 and 13 satisfy the conditions specified
in Findings No. 16a and 16b.
18. The South Tahoe Public Utility District will be using

also transfer the necessary coverage required to fully
mitigate the impacts of coverage and disturbance in the
manner prescribed by Subparagraph 20.4A(2)(o) of the
TRPA Code of Ordinances.
19. Based upon Findings No. 12 through 18, the Construction
of Fallen Leaf Lake Collection System Improvements is
found to be exempt from the prohibition stated in
Finding No. 8.
20. Runoff from the project site, as well as sewage
overflows, flow into drainage channels leading to
Fallen Leaf Lake. Fallen Leaf Lake is within 500 feet
of the project area. Ground water is less than 20 feet
below the ground surface of the project area.
21. The Regional Board adopted a Water Quality Control Plan
for the North Lahontan Basin on June 26, 1975 and this
Order Implements that Plan as amended.
22. The beneficial uses of Fallen Leaf Lake as set forth
and defined in the Water Quality Control Plan for the
