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.

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 43266:ADD 310 Fallen Leaf Phase I ADD .l May 14, 1990 WO #3266B.10 SENT BY:Xerox Teleccpier 7020 ; 5-11-90 : 13:16 : DRAFT SOUTH TAHOE PUBLIC -3 UTILITY DISTRICT CONSTRUCTION OF FALLEN LEAF LAKE COLLECTION SYSTEMS IMPROVEMENTS El Dorado County PAGE 9 OF 36 9165410614-4415 930 0208 :4 5 BOARD ORDER NO. 6 -90 -(TENT) WDID NO. 6A099003002 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 W3266:PDD BIO Fallen Leaf Phase I ADD tl May 14, 1990 WO #3266B.10 SENT BY:Xerox Teleccpier 7020 ; 5-11-90 ; 13:'7 ; DRAFT SOUTH TAHOE PUBLIC -4- UTILITY DISTRICT CONSTRUCTION OF FALLEN LEAF LAKE COLLECTION SYSTEMS IMPROVEMENTS El Dorado County PAGE 10 OF 36 9185410814-+415 930 0208 6 BOARD ORDER NO. 6 -90 -(TENT) WDID NO. 6A099003002 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 best management practices throughout the entire project. The South Tahoe Public Utility District will 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 North Lahontan Basin, as amended, are; a. b. c. d. e. municipal and domestic supply water -contact recreation non -water -contact recreation cold freshwater habitat wildlife habitat 23.

The State Water Resources Control Board adopted the Lake Tahoe Basin Water Quality Plan on October 29, 1980, and amended the plan on January 20, 1983 and June 22,' 1989. This Order implements the Plan as amended. The Plan contains water quality objectives for Lake Tahoe and its tributaries. To the extent of any inconsistency, the Lake Tahoe Basin Water Quality Plan as amended supersedes the Water Quality Plan for the North Lahontan Basin. 23. South Tahoe Public Utility District has prepared a Final Negative Declaration regarding this project in accordance with tha California Environmental Quality Act (Public Resources Code, Section 21000 et seq.) and the State Guidelines. The South Tahoe Public Utility District certified the Final Negative Declaration on May 24, 1990. 26. The Construction of the Fallen Leaf Lake Collection System Improvements as approved by the South Tahoe Public Utility District will not have a significant effect on water quality. 27. The Board has notified the Discharger and the interested agencies and persons of its intent to prescribe waste discharge requirements for the project. 28.
