DISCUSSION: With approximately 15-20 percent of the collection system in easements, the clearing of easements is an important part of the overall maintenance of the collection system. The clearing of these easements is done by the use of 2 seasonal employees. These employees locate manholes, clear and chip the brush, stake the location of the manholes and stencil the manhole number on the cover for easy recognition within the easements. These seasonal employees will be used from July 1,2007 to September 28,2007.

DISCUSSION: On October 17, 2006, approximately 329 gallons of NO.2 diesel fuel was discharged through a former fill/vent line of the 1600 kW emergency generator trailer, near the Trout Creek Sewer Pump Station at the Wastewater Treatment Plant (WWTP). Over-excavation, removal and disposal of approximately 284 tons of petroleum contaminated soil and the pumping and disposal of approximately 324,200 gallons of petroleum-contaminated groundwater was completed during the fourth quarter of 2006. Groundwater monitoring to assess the extent of petroleum hydrocarbon contamination remaining in shallow groundwater was completed during the first quarter of 2007. In May 2007, the Regional Water Quality Control Board - Lahontan Region (LRWQCB) requested that the District submit a work plan to determine the lateral extent of contamination at the non-detect boundary surrounding the spill area. The District developed the work plan which was approved by LRWQCB staff in June 2007. Approval of the FWEST proposal provides full-time oversight, drilling services and reporting required to implement the approved work plan. Staff intends to submit this cost to our insurance carrier. SCHEDULE: July 2007 - September 2007 COSTS: $10,992 (estimated) ACCOUNT NO: 1004-4405/DSPILL BUDGETED AMOUNT REMAINING: $4,000 ATTACHMENTS: Proposal for Groundwater Assessment of the October 17, 2006 Diesel Spill at the Waste Water Treatment Plant, South Lake Tahoe, CA, dated June 25,2007. -3- Bergsohn July 5, 2007 Page 2 CONCURRENCE WITH REQUESTED ACTION: GENERAL MANAGER: YES~ NO CHIEF FINANCIAL OFFICER: YES ~Y'Y"L:- ~O -4- CATEGORY: Water FARR WEST ENGINEERING June 25, 2007 Mr. Ivo Bergsohn, P.G., C.Hg. District Hydro-Geologist South Tahoe Public Utility District 1275 Meadow Crest Drive South Lake Tahoe, California 96150 Subject: Proposal for Groundwater Assessment of the October 17,2006 Diesel Spill at the Waste Water Treatment Plant, South Lake Tahoe, CA Dear Ivo: Attached is our cost estimate to conduct and provide full-time oversight of the workplan activities as submitted to the California Regional Water Quality Control Board - Lahonton Region (LRWQCB). Activities will include all drilling and sampling activities described in the workplan attached to your request for proposal dated June 11, 2007. Actual on site activities will address any modifications to the work plan proposed by the LR WQCB and approved by the District. The Cost Estimate is provided for budgetary purposes, our billing will be on a time and materials basis. Three tasks are identified to include the work items indicated in your letter. Costs are estimated separately for Project Management, Site Supervision, and Reporting. Two days of field work are scheduled for marking the boring locations and directing field activities described in the Work Plan - WWTP Emergency Generator Diesel Spill, SCP Case No. T6S060. The field work is to include as many as 8 Geoprobe sampling locations with the collection of continuous core samples of soil and discrete depth groundwater samples collected from the boring. Analytical analysis of samples will be coordinated by the District's laboratory. Farr West Engineering estimates contractor and equipment costs at $3000 (drilling proposal attached). Fisch Drilling is estimating that the Work Plan can be completed in 1 day at a daily (8-hour) rate of$1500 plus unit costs as provided on the attached contractor proposal. All holes in the vicinity of utilities based on the utility map supplied by the STPUD or as marked on the ground during the utility clearance will be hand dug prior to using the Geoprobe. The Geoprobe 6600 method provides several advantages to the other available methods. If this method is unsuccessful at any of the locations the drilling contract will need to offset the location within the utility clearance area and make a second attempt. Repeated attempts should allow the probe an opportunity to advance along side any boulders that may have caused refusal of the probe. Depending on site conditions continuous cores may be collected at all 8 proposed locations without a significant (<$100.00) increase in project costs. Continuous lithologic logs will only be completed for the locations as identified in the W orkplan. This proposal assumes that the District will provide analytical sampling containers and contract and cover laboratory costs for 5442 LONGLEY LANE, SUITE B . RENO N?1i9511 . (775) 851-4788. FAX (775) 851-0766 June 25, 2007 Page 2 analytical analysis. Costs for project/field supervision are based on completing the drilling in one day using the Geoprobe method. The total budget is estimated at $10,992 (see attached table). The Cost Estimate is based on the following assumptions: . The Project Manager will be Dr. Kirk Swanson, Ph.D., P.G., C.Hg. ofFarr West Eng. . Field oversight of sampling activities will be by Alex Macy ofFarr West Eng. . Farr West will implement the traffic control plan . The drilling contractor will complete the field activities within 8 hours . Field expenses and contractor costs will be billed on a cost plus ten percent administrative fee basis . Sampling containers and laboratory costs will be paid by the District Farr West Engineering and Fisch Environmental can complete the fieldwork on July 30th 2007. lIDs will allow sufficient time for the W orkplan to be finalized and completion the fieldwork prior to August 3rd, 2007 as described in the Workplan. A report for submission to the LRWQCB summarizing the findings will be completed in October 2007. This allows two weeks for laboratory analysis and approximately 6 weeks for preparation, review and finalization ofthe report. In addition to many rural water districts Farr West Engineering is presently under contract with several large public entities including the State of Nevada ($1,300,000), Truckee Meadows Water Authority, Douglas County and Washoe County with stringent insurance requirements. Our insurance limits exceed our current client requirements and the requirements of a recent RFP by the Truckee Donner Public Utility District. Farr West's standard insurance limits for general commercial liability are $2,000,000 each occurrence and $4,000,000 general aggregate. Automobile liability coverage is $1,000,000 each accident (see attachment). I have worked for the District since the early 90s and look forward to again providing professional hydro-geologic consulting services to the South Tahoe Public Utility District on this project.

DISCUSSION: The District is planning to install an in-reservoir aeration system in Indian Creek Reservoir (lCR). To ensure proper installation of the aeration unit, a probe examination of an area roughly 40m by 40m of the reservoir bottom is required. The purpose of the probe examination will be to locate a level and debris free area for installation of the submerged aeration system. On June 12,2007, the District solicited a request for quotes to conduct diving services at ICR. The request was sent out to five diving contractors for bids. As of June 27,2007, four (4) bids have been received. Based on review of the submitted bids, staff recommends that the Board approve the bid from Subaquatic Solutions to complete this work. Grant funding is contributing to this project.

Comment 1: "Planned project would be in a residential area on a residential lot, which should not be pennitted." Response: EI Dorado County Zoning Ordinance 17.56.030 (C) includes "Public utilities buildings and structures other than distribution and transmission lines" as an allowable use within the TR-1 one-family residential zone after obtaining a special use permit from the planning commission. Entrix, on behalf of the District submitted application items and accompanying fees to the Development Services Department (DSD) for a Special Use Permit (Application S 07-0010) in February 2007. On March 29. 2007, the DSD deemed the application complete for processing. On June 14,2007, Tom Dougherty, Associate Planner, EIDorado County Planning Department notified the District that a Special Use Permit would not be required for this project. Legal opinion from the County and District concur that this project is exempt from County building and zoning ordinances under Section 53091 of the Government Code. Comment 2: 'The planned building and driveway etc. would be way over allowed TRPA coverage. " Response: The excess coverage for this project is estimated at 1,403 square feet. The District shall offset this impact through the acquisition of potential land coverage rights and permanently retire said rights in the amount of 1,403 square feet. The TRPA code allows excess coverage for public health and safety projects. South Tahoe Public Utility District. 1275 Meadow Crest Drive, South Lake Tahoe, CA 96150 Phone 530.544.6474. Facsimile 530.541.0614 · www.stoud.us 1 -17- Comment 3: "It would substantially decrease property value in the neighborhood." Response: The majority of District water supply wells are situated within residential neighborhoods. Several of these sites (ClementWell-1992, Bakersfield Well- 2004, Arrowhead Well - 2001) include treatment facilities. While it is difficult to obtain the necessary historical data on a neighborhood by neighborhood basis on such short notice, the readily available South Tahoe Board of Realty data indicates double digit Median Prices by Area in South Lake Tahoe and no correlation between sales price and proximity to a drinking water well. Property values in the South Tahoe area do not appear to have been adversely affected by existence of these facilities. Comment 4: "Noise and transportation traffic would be significant." Response: The District appreciates and values the serenity of this area and will take all reasonable steps to maintain this condition. Facilities and equipment will be installed as necessary to meet the 50db community noise limitation. In addition, the District intends to install additional or expanded features as necessary to control noise and particular frequencies and modulations that may present a nuisance to the neighborhood. Noise control was a major issue during the District's design process that resulted in the following sound dampening features: 1. All mechanical equipment will be housed within a concrete block. building 2. A submersible pump and motor set in the production well; 3. A universal inlet silencer and sound attenuation wrap will be installed on the aeration blower and motor; 4. Sound dampening board will be installed"on the interior ceiling and walls of the mechanical building; 5. A noise silencer will be placed on the air inlet; and 6. The air inlet will be directed toward the west, away from neighboring residences. Although we believe these systems will provide the necessary noise control, additional equipment and/or features will be installed if necessary. The District is open to having the TRPA assist or consult in the completion of a sound survey. The District estimates an average of two trips per day would be generated by the project for routine operations and maintenance. EI Dorado County estimates that this is less than a quarter of the TransportationlTraffic generated by a single-family residence (estimated at an average of 10 trips per day). Transportation traffic is addressed in the draft IS/ND, Appendix A, Section XV - TransportationlTraffic. According to the draft ISIND, TransportationlTraffic from the project would have a less than significant impact or no impact. Comment 5: "Taking arsenic, C02 and radon out of the water and then blowing it into the air, for us to breathe, does not make much sense."

Facsimile 530.541.0614. www.stoud.us 2 -18- Response: The District retained a qualified water treatment specialist (Robert Ryder, P.E., Kennedy/Jenks Consultants) to complete a Corrosion Control Study in conformance with Department of Health Service (DHS) requirements. This study included an initial screening of corrosion control options (including use of silicate and phosphate inhibitors, pH adjustment by lime or sodium hydroxide addition and aeration) the findings from a field study pilot test and a recommended treatment alternative. Based on the findings of the study, the recommended treatment option (low profile aeration with chemical addition, if necessary), was approved by the DHS on April 9, 2007. The proposed project would implement the recommended treatment option. Comment 6: 'There would also be substantial noise pollution, caused by air intake and air outlet chimneys. n Response: See response to Comment 4. Comment 7: 'The proposed project would have a VFD - driven pump. VFD motors cause radio interference. STPUD has been polluting the airwaves in this neighborhood for years. This will not be permitted any longer. n Response: A variable frequency drive (VFD) will be used as a motor control for the booster pump in order to pump treated water from the discharge side of the aerators into the water distribution system at the required pressures and discharge rates. VFDs are advantageous in providing increased motor speed and torque control, as well as providing improved operation energy efficiency and reduced mechanical wear and tear on motor components. It is believed that with proper installation, radio frequency interference problems associated with VFDs can be minimized and possibly eliminated. The following paragraph has been referenced in the specifications for the VFD. The standards referenced are internationally recognized standards that provide guidelines for suppressing and limiting electromagnetic interferences: 1. "The VFD shall fulfill all electromagnetic compatibility immunity requirements per the following standards utilizing input and output EMIIRFI filters. These filters shall suppress all objectionable interference to AM and FM radio signals in the immediate vicinity of the facility. a. IEC 61800-2 and -3. b. EN 50082-1 and -2. c.

The active ingredient in household bleach is 5% sodium hypochlorite. Since 1989, sodium hypochlorite has been safely and properly used at the South Upper Truckee site without incident. Sodium hypochlorite for this project will be contained in a double-walled 400-gallon tank within the chemical room. Any spills from the tank would be contained within the building and directed to the floor drain to the District sanitary sewer. The District has been using diesel fuel to power emergency stand-by generators at six (6) drinking water well facilities through the South Tahoe area, including the South Upper Truckee site. Diesel fuel has been used at the South Upper Truckee site since installation of the emergency power generator in 1993. Diesel fuel for this project would be contained within a 200 gallon double-walled belly tank underlying the generator within the building. Spill buckets would be used to clean-up spills from the tank. The proposed project will not change the use of sodium hypochlorite or diesel fuel at the site. The District has developed a Hazardous Materials Business Plan to be filed with the EI Dorado County Environmental Management Department, prior to construction of the facility. The Hazardous Materials Plan includes a training plan that informs District staff on the proper use of spill clean-up procedures, notification requirements and the proper handling of hazardous materials used at this site. Comment 9: "Objectionable odors may also be created." Response: During the fall of 2006, the District completed an approximately nine (9) week field pilot test using low profile aeration. Objectionable odors from the aerated water were not observed during the pilot study. South Tahoe Public Utility District. 1275 Meadow Crest Drive, South Lake Tahoe, CA 96150 Phone 530.544.6474.

" Response: The need for this project was initially discussed during a Board Workshop convened in October 2005. In December 2005, the Board authorized staff to request proposals from consulting engineering firms to conduct a Corrosion Control Study (CCS) for the South Upper Truckee Well No.3, in accordance with California Safe Drinking Water Act Requirements. In February 2006, the Board approved staff recommendation to select Kennedy/Jenks Consultants (K1JC) to conduct Phase I of the study. In June 2007, the Board approved Phase" of the CCS. In March 2007, Kennedy Jenks Consultants (K1JC) provided a 20-minute presentation describing the purpose, methods and major findings from the Corrosion Control Study. In April 2007, the District conducted a neighborhood meeting that discussed plans for the construction of the CCS water treatment facility. At each of these meetings, the public has had an opportunity to provide input on this project. Comment: 'We think that your staff and consultants have not done their homework and fully investigate the precedent your district is setting for the Tahoe Basin, State of California and the nation." Response: Please note that the purpose of the draft initial study (IS) is to show the probable environmental effects of the proposed project. The need for the project is based, in part, on the Treatment Alternative recommended in the District's Arsenic Compliance Plan, completed in 2005. In November 2005, the District Board directed staff to continue work on the Treatment Alternative including completion of the South Upper Truckee Well No.3 Well Controls Building Facility project. Corrosion control treatment was added to the project due to the corrosive nature of the produced waters and to remain compliant with the Federal and State Lead and Copper rule. The District retained K1JC to complete a Corrosion Control Report (CCR) that was submitted to the California Department of Health Services (DHS) in February 2007. The DHS approved the corrosion control treatment option recommended in the CCR in April 2007. Comment: 'We attended the STPUD neighborhood meeting on Friday, April 13 hosted by your staff and consultants to the project. Most of the concerns and questions could not be adequately answered by your team. In fact, the more we questioned the project, the more obvious it was how little research had been done into the long-term health and environmental impacts of this STPUD project." Response: At the time of the April 13 neighborhood meeting, the environmental review for the project was in-progress and results from that review were either incomplete or not available. Many of the questions and concerns raised at the meeting are addressed in the May 18, 2007 draft IS/NO document. This document was made available for public review, starting on May 19, 2007.

CA 96150 Phone 530.544.6474 · Facsimile 530.541.0614 · www.stoud.us 5 -21- Comment 1: "The dangerous release of radon in a neighborhood 13' above the ground on a possible 24/7 basis, year-round and within 100' of surrounding homes is absolutely unacceptable, and the potential health and environmental impacts to surrounding neighbors, the ecosystem and the community is such an egregious violation of your public duty." Response: The release height of the outlet chimney is 20.67 feet above the surrounding ground elevation. Based on historical usage, it is estimated that the South Upper Truckee Well facility would most likely be operated on a daily average basis, about 14 hours per day. Radon is a naturally-occurring radioactive gas that is ubiquitous in groundwater sources located in the South Tahoe Groundwater Basin. Radon is present in all of the District's water sources ranging in average concentrations from 502 picocuries per liter (pCill) to 5,615 pCi/L. The average concentration of radon found in District drinking water is on the order of 1,750 pCilL. The source of this gas is believed to be from the release of radon into groundwater, from the granitic bedrock and soils that surround and fill the basin. As noted in the draft IS/ND, Appendix E, Section 5.0 - EPA RADON MAP FOR CALIFORNIA, South Lake Tahoe is situated in an area with a moderate predicted average indoor radon screening level. The DHS has found elevated levels of radon in some homes in portions of the Lake Tahoe area. It is clear that radon is not a new phenomenon, but is a natural part of the surrounding environment. Environmental impacts to the release of radon from the proposed project is addressed in the draft IS/ND, Appendix E, Section 4.0 - EXPOSURE ASSESSMENT. Findings from the exposure assessment shows that average ambient concentration of radon gas in zone of maximum impact (that is 62 feet from the outlet chimney at a height of 59 inches above surrounding ground elevation) would be equivalent to a 1.6% of EPA's average nationwide outdoor radon level (0.4 pCilL). These radon concentrations are not believed to pose a significant risk to public health on a lifetime exposure basis. Comment 2: 'We are again appalled, by your utilization of an untested method on the neighborhood. Upon questioning your staff and consultants at the neighborhood meeting, they admitted that the radon emissions was untested and there were no other operations like STPUD is proposing." Response: At the April 13 neighborhood meeting, District staff noted that attempts were made to find a laboratory that would conduct outdoor radon emissions monitoring during the field pilot study. Unfortunately, this portion of the pilot study was not completed, as the District staff and its consultant were unable to find a suitable lab that could provide these services. From 1993 through about 1999, the District operated a packed-tower air stripper to remove Tetrachloroethylene (peE) from drinking water produced in the Gardner Mountain area. The facility was shut down owing to MTBE contamination making the South Tahoe Public Utility Dlsbict. 1275 Meadow Crest Drive, South Lake Tahoe, CA 96150 Phone 530.544.6474 · Facsimile 530.541.0614 · www.stDud.us 6 -22- wells unusable. Water from this well contains radon gas at concentrations ranging from 800 pCilL to 3,055 pCi/L. The radon gas was released to the atmosphere along with the PCE through the treatment process. Both packed-tower air strippers and multi-stage bubble chambers are similar processes in that both use aeration to remove volatile gasses dissolved in groundwater. This facility is a newer-generation aeration unit. Comment 3a: 'We are concerned by the potential low level humming noises on a 24/7, year round basis, that will occur as a result of the pumps running in the valley." Response: See response to H & M Marty (06/13/07), Comment 4. Note that this property has been used as a well facility since the early 1960's. The District is unaware of any noise complaints from these operations. Comment 3b: "This industrial operation has no place in a residential setting." Response: The state of California recognizes that public facilities used for the production, generation, storage or transmission of water are indispensable and must be located at the discretion of the water district to assure the efficient and economic delivery of drinking water to its customers. The District has completed engineering planning studies showing the need and utility of the proposed project, as the most cost effective means to continue to provide adequate quantities of safe drinking water that meets the South Lake Tahoe community's needs. See also response to H & M Marty (06/13/07), Comment 1. Comment 3c: "This size and magnitude of this project does not meet a reasonable standard for residential operation." Response: The project is sized to meet the objectives of the intended use of the well controls building and treatment facility. The District retained an Architect that designed the facility in such a manner to conform to the residential setting. The majority of District drinking water well facilities are situated in residential neighborhoods throughout the South Tahoe area. Many of the surrounding neighbors are unaware of there existence, due to the unobtrusive design and operation of these facilities. See also response to H & M Marty (06/13/07), Comment 2. Comment 3d: ''This project will forever destroy the beauty and serenity of this scenic and pristine river, wildlife corridor and recreational area so critical to the Tahoe Basin." Response: This property has been used as a well facility since the early 1960's, without any detrimental effects to the surrounding area. Native habitat does not occur on this site.

Facsimile 530.541.0614 · www.stoud.us 8 -24- Dr. Gary Fisher (06/14/07): Comment: Radon eX/Josure and emission Is reaulated bv both the EPA and the FDA. The maximum allowable EPA and FDA limit on radon levels before remediation is required is 4 pCi/L. Please note that the STPUD proposes to release 30 pCllt from their 13 foot tall stackl This Is 7.5X the allowable EPA maximum that reaulres immediate remediation.. Response: The comment includes the concentration reduction in the aeration unit, but neglects to consider concentration reduction by dispersion. This process will lead to an annual average concentration of 0.0064 pCilL, which is 0.16% of the EPA action level. Question 1: "How can the community be sure that, even if the STPUD says it isn't using the radon-contaminated water, that STPUD isn't using it anyway without informing you?" Response: The District has been providing a safe and reliant source of drinking water to it's customers since 1973. The District is required to sample water that it provides to its users, and report these results to its users. The District regularly provides Consumer Confidence Reports (CCRs) detailing the quality of its drinking water provided, including natural radioactivity, in accordance with California Safe Drinking Water Act laws and regulations. Though radon is not currently regulated by the EPA or the state, we report radon in our CCR. Question 2: "The STPUD document talks about using the radon-rich wells that are better producers of water than wells in the same area; doesn't that strike fear into anyone else but me? Is the well that STPUD is all ready using contaminated? How close are their current wells to the new one they are proposing to use?" Response: All District drinking water sources contain some levels of dissolved radon. The District is proposing to treat a well having low levels of arsenic, for corrosion control, rather than having to treat a well having high levels of arsenic, for arsenic. Operationally, it is more cost effective to treat water for corrosion control than for arsenic removal. The subject property has been used as a well facility since the early 1960's. The District has produced drinking water from the South Upper Truckee (SUT) Well No.1 and the former South Upper Truckee Well No.2 for more than twenty years. Both the SUT No.1 and former SUT No.2 wells have similar chemistry as the new SUT Well No.3. These wells are situated within 50 feet of each other. The existing wells have had levels of radon within safe levels. Question 3: 'Will the aeration be carried out 24/7? If so, then 24/7 monitoring of the radon being released from their stack should be required" South Tahoe Public Utility District. 1275 Meadow Crest Drive, South lake Tahoe, CA 96150 Phone 530.544.6474. Facsimile 530.541.0614. www.stoud.us -259 Response: The well, and aeration unit, will be used as needed, from less than one hour to continuously. Based on historical usage, it is estimated that the South Upper Truckee Well facility would most likely be operated on a daily average basis, about 14 hours per day. Environmental impacts to the release of radon from the proposed project is addressed in the draft ISIND, Appendix E, Section 4.0 - EXPOSURE ASSESSMENT. Findings from the exposure assessment shows that average ambient concentration of radon gas in zone of maximum impact (that is 62 feet from the outlet chimney at a height of 59 inches above surrounding ground elevation) would be equivalent to a 1.6% of EPA's average nationwide outdoor radon level (0.4 pCVL). These radon concentrations are not believed to pose a significant risk to public health on a lifetime exposure basis. Based on the results of the impact assessment, the impact does not require monitoring or mitigation as suggested in the comment. Question 4: 'Will the highly charged and far more dangerous radon daughter nuclides be monitored?" Response: At this time, the project does not include a requirement for radon air emissions monitoring. Question 5: "Are there any studies of airflow patterns from the proposed exhaust stack over the entire neighborhood to be able to reliably predict where the radioactive plume will spread, how far the plume will spread, and how fast the plume will dissipate?" Response: Details regarding the dispersion analysis used in the radon gas exposure assessment are provided in the draft ISIND, Appendix E, Section 3.0 - DISPERSION ANAL YSIS. The model makes conservative (worst-case) assumptions in order to provide an upper bound on the maximum concentration that could be emitted. Consideration of more site-specific conditions would lead to lower concentrations. Since the result of the screening level model produced such a minor concentration, the more site-specific modeling was not needed for impact assessment purposes. The screening analysis showed that annual average outdoor concentrations of radon gas would increase by 1.6% or less of EPA's average nationwide outdoor radon level in any location with respect to the exhaust stack. Question 6: "Radon can be adsorbed very effectively using carbon block filters that ultimately, must be treated as radioactive waste; has the STPUD investigated this much safer option for radon removal?" Response: Drinking water regulations for radon have been proposed, but have not been adopted. The proposed Radon in Drinking Water Rule would provide an enforceable maximum contaminant level (MCL) of 300 pCi/L and alternative MCL of 4,000 pCi/L. The drinking water standard that would apply would be contingent on whether the State or Community Water System developed a multimedia mitigation South Tahoe Public Utility District. 1275 Meadow Crest Drive.

The District will consider radon treatment after the Radon in Drinking Water Rule is adopted. Question 7: "Aeration removes 30 - 70% of total radon; the rest remains in the water as an ingestion hazard. Does the STPUD have any studies that show aeration to be more effective than that? Even a 70% removal leaves 8-9 pCi/L unaccounted for, nearly the double maximum allowed by the EPA and FDA.". Response: During corrosion control treatment pilot testing, water quality sampling showed a greater than 90% reduction in dissolved radon concentration using bubble aeration. During pilot testing, influent radon concentration averaged 483 pCil and effluent radon concentration averaged 24 pCi/L. It is our understanding that a drinking water standard for radon has not been adopted by the EPA. Question 8: "The cost of a potential lawsuit will offset by many orders of magnitude any savings this new hazardous water source might produce; are the STPUD board members aware of Love Canal?" Response: Yes, STPUD Is aware of "Love Canal". There is no evidence to support the contention that the new water source is hazardous. The subject property has been used to provide drinking water since the early 1960's. Drinking water produced from this site has met all state and federal drinking water standards. The District has worked closely with the Department of Health Services to insure that this site and the South Tahoe PUD water system will continue to provide a safe and reliable source of drinking water to meet the needs of its customers. Question 9: "According to STPUD's own document, the savings resulting from using this new radon-contaminated water source would be small; wouldn't it be wiser to charge a tiny bit more to the rate payers and guarantee safe water and safe air around the plant? .There is not just faulty reasoning here, there is no reasoning?" Response: The purpose of the draft IS/ND is to evaluate the potential environmental impacts from the proposed project. District planning studies suggest that District water treatment costs could be significantly reduced by cost effective corrosion treatment at the SUT Well No.3. It is unclear to which STPUD document is being referenced. Question 10: "Have you investigated any links between STPUD and other investors or sources of unseen funding?" Response: The District is a public agency, formed in 1950, that provides wastewater collection, treatment and recycling and drinking water to the community of South Lake Tahoe. The District provides a comprehensive annual financial report (CAFR) each fiscal year that includes an independent auditor's report. The District has received numerous awards from the Government Finance Officers Association for its excellence South Tahoe Public Utility District · 1275 Meadow Crest Drive. South Lake Tahoe.

Fleck (06/19/07) Item 1) Noise: Concems about increase in noise levels and request for an onsite demonstration and noise impact report: Response: The District appreciates and values the serenity of this area and will take all reasonable steps to maintain this condition. Facilities and equipment will be installed as necessary to meet the 50db community noise limitation. In addition, the District intends to install additional or expanded features as necessary to control noise and particular frequencies and modulations that may present a nuisance to the neighborhood. Noise control was a major issue during the District's design process that resulted in the following sound dampening features: 7. All mechanical equipment will be housed within a concrete block building 8. A submersible pump and motor set in the production well; 9. A universal inlet silencer and sound attenuation wrap will be installed on the aeration blower and motor; 10. Sound dampening board will be installed on the interior ceiling and walls of the mechanical building; 11. A noise silencer will be placed on the air inlet; and 12. The air inlet will be directed toward the west, away from neighboring residences. Although we believe these systems will provide the necessary noise control, additional equipment andlor features will be installed if necessary. The District is open to having the TRPA assist or consult in the completion of a sound survey. Item 2) Hazardous Materials Business Plan: Request for additional reasonable time to review and comment on completed Hazardous Materials Business Plan: Response: The Hazardous Materials Business Plan is currently in draft form and is being completed in compliance with and as required by the EI Dorado County Environmental Management Department. This plan includes information on two materials, sodium hypochlorite (similar to household bleach) and diesel fuel, that meet the reporting requirements set by the County. The District's draft plan includes general materials information, estimated voJume of consumption, materials handling and storage procedures, and emergency contacts, response procedures and precautions. This is basic information that the County requires to assess potential hazards and to make sure that the necessary procedures and precautions are in place before the facility goes online. The District has been using sodium hypochlorite as a disinfectant at drinking water wells since 1989. Sodium hypochlorite has been used atthe South Upper Truckee site without incident since 1989. The sodium hypochlorite will be contained in a double- walled 400-gallon tank within the chemical room. Any spills from the tank would be contained within the building and directed to the floor drain to the District sanitary sewer.

Diesel fuel has been used at the South Upper Truckee site since installation of the emergency power generator in 1993. Diesel fuel for this project will be contained within a 200-gallon double-walled belly tank underlying the generator within the building. Spill buckets would be used to clean-up spills from the tank. The Hazardous Materials Business Plan will not be completed and approved by the County for perhaps several months and does not need to be completed until the well is ready for startup operations in March 2008. The District is completing this Plan as required by the EI Dorado County Environmental Management Department for their review, comment, and approval. A public review period is not part of this process and we believe unnecessary in this case based on the benign, common nature of the two reportable materials, sodium hypochlorite and diesel fuel. If you would like to review the draft or final plans, you will need to contact Virginia Huber at the EI Dorado County Environmental Management Department, 3368 Lake Tahoe Blvd., South Lake Tahoe, CA, 96150. Item 3) TRPA Initial Environmental Checklist for Determination of Environmental Impact: - I disagree with the following statements contained in the checklist, all of which are checked "No" by STPUD and I believe the reasonable answer to each of these should be a "YES", barring absolute data to the contrary (such as a full EIR), or "Insufficient Data" when no long term data was ,shown for the conclusion. The point of my objections is in parenthesis following each statement: 2. Air Quality of ambient (existing) air quality?... Will the proposal result in... (b) Deterioration of ambient (existing) air quality? (Increase to ambient radioactive radon emissions - actual levels of ambient, and actual future levels of increased, unknown - insufficient site data) Response: A dispersion analysis was performed using a conservative model that provides "worst-case" impacts. The screening analysis showed that annual average outdoor concentrations of radon gas would increase by 1.6% or less of EPA's average nationwide outdoor radon level in any location with respect to the exhaust stack. STPUD cannot be expected to control the ambient level of radon in Christmas Valley, however, its model shows that this project's impact on the air quality is much less than the EPA's standards. (c) The creation of objectionable odors (Diesel fuel and hazardous chemical usage) Response: The project will not create objectionable odors. During the fall of 2006, the District completed an approximately nine (9) week field pilot test using low profile aeration. Objectionable odors from the aerated water were not observed during the pilot study. South Tahoe Public Utility District. 1275 Meadow Crest Drive, South Lake Tahoe, CA 96150 Phone 530.544.6474. Facsimile 530.541.0614. www.stoud.us 14 -30- (d) Alteration of air movement, moisture or temperature, or any change in climate, either locally or regionally? (Air dispersion procedures?) Response: Since ambient air will be used in the deep bubble aerators, air will leave the building at the same temperature and moisture level. The area of impact the blowers that accelerate air from the stack are minor and cannot alter air movement. (e) Increased use of diesel fuel? (200 gallon on site storage and use) Response: Diesel fuel has been used at the South Upper Truckee site since the installation of the emergency power generator in 1993. No change is proposed to the use or amount of diesel fuel at the site. 3. Water Quality... Will the proposal result in... (j) The potential discharge of contaminants to the groundwater or any alteration of groundwater quality? (There is always the potential for hazardous chemical discharge when there is hazardous chemical storage at a site - no disaster mitigation plan has been presented to the public for review and comment) Response: The District has been using sodium hypochlorite as a disinfectant at drinking water wells since 1989. Sodium hypochlorite has been used at the South Upper Truckee site without incident since 1989. Sodium hypochlorite for this project will be contained in a double-walled 400-gallon tank within the chemical room. Any spills from the tank would be contained within the building and directed to the floor drain to the District sanitary sewer. The District has been using diesel fuel to power emergency stand-by generators at six (6) drinking water well facilities through the South Tahoe area, including the South Upper Truckee site. Diesel fuel has been used at the South Upper Truckee site since installation of the emergency power generator in 1993. Diesel fuel for this project would be contained within a 200 gallon double-walled belly tank underlying the generator within the building. Spill buckets would be used to clean-up spills from the tank. The proposed project will not change the use of sodium hypochlorite or diesel fuel at the site. The District has developed a Hazardous Materials Business Plan to be filed with the EI Dorado County Environmental Management Department, prior to construction of the facility. The Hazardous Materials Plan includes a training plan that informs District staff on the proper use of spill clean-up procedures, notification requirements and the proper handling of hazardous materials used at this site. (k) Is the project located within 600 feet of a drinking water source? Response: The project is at least 1,080 feet from each of the 3 neighboring private wells in the area. Although the project itself is providing drinking water, it is not considered a drinking water source because the water must go through treatment before it is considered potable.

Facsimile 530.541.0614 · www.stoud.us -3115 (d) Deterioration of existing fish or wildlife habitat quantity or quality? (Insufficient data given to determine long range impact of chemical and radon impact on wildlife) Response: Wildlife will not come in contact with chemicals (See response to 3. Water Quality... will result in...). Assuming that the same regulations for human health apply to wildlife, the "worst case" model showed radon emissions were well within EPA regulations and 1.6% or less of the EPA's average nationwide outdoor radon level of 0.4 pCi/L in any location. 6. Noise... Will the proposal result in... (a) Increases in existing Community Noise Equivalent Level (CNEL) beyond those permitted in the applicable Plan Area Statement Community Plan or Master Plan? (Should have at least been "No, with mitigation") Response: The project itself, without mitigation required elsewhere, is designed to meet the TRPA CNEL of 50 decibels for the Christmas Valley Area. The following measures are not mitigation measures but are components of the project: 1. All mechanical equipment will be housed within a concrete block building 2. A submersible pump and motor set in the production well; 3. A universal inlet silencer and sound attenuation wrap will be installed on the aeration blower and motor; 4. Sound dampening board will be installed on the interior ceiling and walls of the mechanical building; 5. A noise silencer will be placed on the air inlet; and 6. The air inlet will be directed toward the west, away from neighboring residences. Construction related activities would generate a short-term increase in ambient noise levels. However, according to Chapter 23.8, construction noise is exempt from the quantitative limits contained in the Noise Ordinance if construction occurs between the house of 8:00 a.m. and 6:30 p.m. 10. Risk of upset... Will the proposal...

(Christmas Valley is a notorious area for cars and boulders coming down off Echo Summit... a few years back a car came off the cliff all the way down to South Upper Truckee and burst into flames. The project is almost in a direct line from the gulley below Echo Summit where several cars have careened over the side, intentionally and otherwise, in the past few years... 2 such incidents alone last year. The valley is also a "low flying" area for helicopters, so it would be very prudent to consider the possibility for "upset conditions" more than has been done in the STPUD proposal). Response: The project itself does not involve the risk of explosion. It is possible a car could drive off the cliff on Echo Summit or a catastrophic earthquake could occur, but the same dangers could occur with any project in the Christmas Valley Area.

Will the proposal result in... (a) Creation of any health hazard or potential health hazard (excluding mental health)? (To ignore the potential long term health implications of radon emissions, first with insufficient data to support the presumption in the STPUD proposal that there IS no impact, and secondly to overlook the necessity for long term monitoring of the radon emissions, is negligent). Response: STPUD does have sufficient data to support both the amount of radon emissions from the project and human exposure to the radon emissions. Using mass balance along with a conservative model, STPUD presented the "worst case" scenario for radon exposure and still was well below the EPA's risk guidelines. As for potential long term health implications, STPUD is relying on the EPA's standards for outdoor radon concentrations. . (b) Exposure of people to potential health hazards? (Data exists to support that constant noise, radon and hazardous chemicals all can have long term health consequences, it's simply a matter of exposure patterns, which has not been adequately considered in the STPUD proposal that declares it will bring these factors into our neighborhood yet by STPUD's declaration as the controlling authority, there is no health hazardl).

(a) Be visible from any state or federal highway, Pioneer Trail, or from Lake Tahoe? (The property is visible from Echo Summit which is a TRPA Scenic Corridor. Given the air currents in the valley and sound echoes, it's very possible sound from the project, and any odors, may easily draft upward to Echo Summit. Residents of Christmas Valley can often hear everyday conversations (normal conversation is 60 dB) of tourists who have stopped in the road turnouts to take pictures. Response: The project area is located in a scenic corridor designated by the TRPA (Roadway Unit 37, Echo Summit). While the entry point view's scenic quality is rated "high", there will be no adverse effect on the scenic vista as the structure's appearance will conform to TRPA's Design Review Guidelines. 21.

Response: Using the higher value for Zephyr cover (0.88 pCi/l) results in the incremental additional annual average ambient concentration of radon gas in the zone of maximum impact being 0.7 percent. The local value, therefore, results in the impact of the discharge being less than reported in the Initial Study, and supports the proposed action. Question 2: Amending the calculations to include actual radon emission for this site combined with actual ambient concentrations for the site (completely unknown due to insufficient data) could easily put the supposedly safe ambient emission level proposed by STPUD into the realm of "mitigation recommended by EPA" arena, and that is an unreasonable and completely unacceptable standard to impose on the residents who would be most impacted by this. Response: The actual annual average radon emission concentration from the site will be less than 0.0064 pCi/L. This is 0.16 percent of the EPAs action level of 4 pCi/L and well within measurement uncertainty of radon detection. Therefore, the emission will not have a detectable effect on sites that are already near the EPA action level of 4 pCi/L. Question 3: Given the importance of radon's health hazards and what we don't really know about the long term effects other than there probably are damaging effects, or without sufficient site-specific Christmas Valley data to support any calculations or conclusions created by STPUD, I ask STPUD to amend their proposal and base all their radon data calculations on current, accurate, site specific measurements of radon gas. Response: The calculations of radon emissions from the facility have been based on site-specific water concentrations. The air dispersion model provides conservative results for radon concentrations in air; that is, the model provides a higher level of radon than would actually be emitted from the facility. The radon concentrations are 0.16 percent of EPA's indoor action level for radon, 1.6 percent of the average outdoor radon concentration, and 0.7 percent of the concentration cited by the commenter for Zephyr Cove. The percentage increase in radon from the facility is within the measurement error of ambient levels, and so ambient levels will not be measurably affected by the discharge. Question 4: Radon gas levels are affected by temperature, precipitation, diurnal changes, geology, meteorology, and even the moon, so I would suggest the data be collected at random intervals of night and day, during temperature extremes, seasonal variations and precipitation changes, throughout the designated impact zone as described by STPUD in the proposal. I would also suggest that this data, as well as a full environmental report on the risks and hazards of radon, be prepared by a scientist who specializes in radioactive hazards, then the report be submitted for further public South Tahoe Public Utility District. 1275 Meadow Crest Drive, South Lake Tahoo, CA 96150 Phone 530.544.6474 · Facsimile 530.541.0614 · www.stoud.us 18 -34- review and comment. I would also request that STPUD maintain ongoing, onsite radon emission measurements, and at the neighboring properties closest to the impact zone, as well, to insure there is no dangerous variation in any calculated levels or to begin additional mitigation procedures as required. Response: See response to question 3 regarding site-specific information used to calculate radon emissions from the facility, and the conservative (worst case) nature of the dispersion modeling methods. The proposed testing program is intended to quantify the background levels of radon, and the contribution of the facility. See response to question 3 regarding the percentage contribution of the facility to background concentrations. The more detailed measurement of natural background concentrations are not warranted, based on the de minimus contribution of this source. The Initial Study has a full disclosure of the public health effects of radon. Question 5: It would be irresponsible to calculate the likelihood for human exposure damage based on an assumption that STPUD knows all there is to know about the inherent risks of radon. Response: The assessment has been based on data developed by or on behalf of the US EPA and not by STPUD. The EPA has used the studies to establish safe levels based, and the incremental increase is within measurement uncertainty compared to these levels. In the narrative portion of this comment letter, reference was made to an EPA goal of 0 for radon exposure. As noted elsewhere in the comment, however, background levels due to natural sources are 0.4 pCill on a national basis, and 0.88 pCiIL at Zephyr Cove. As such, zero radon exposure in this setting is not feasible owing to the naturally-occurring sources. South Tahoe Public Utility District. 1275 Meadow Crest Drive, South Lake Tahoe.

Moulia (06/19/071 Question 1: It is morally and ethically wrong for entities handling radioactively concentrated natural sources, such as Tahoe groundwaters, to take steps which radioactively concentrate other pathways (eg air) and force small fractions of the population to bear the brunt of the radiation exposure. The EPA has adopted this position and begun efforts to regulate Technically Enhanced Naturally Occurring Radioactive Materials (TENORM). It has provided guidance on the effects on the public from airborne radon releases from venting of uranium mines. It has also provided guidance to Community Water Districts on proper handling of water treatment and filter mediums which have become radioactively contaminated in the normal course of treating groundwater with high concentrations of Naturally Occurring Radioactive Materials (NORM). Unfortunately, STPUD's proposed method of corrosion control for water from SUT#3 is a novel approach having much the same impact as mine venting of radon, but not yet addressed in regulation. Their proposal clearly meets the intent of what EPA has proposed to regulate under its' TENORM Program but the specifics of which. . . .for this type of corrosion control treatment....have not yet been addressed. I would trust that in an environmentally aware community such as Tahoe, in an environmentally sensitive area such as Tahoe, that all involved would wish to meet not just the letter of environmental regulation but also the intent. Response: The approach taken in the impact assessment is to compare the increase to standards set by EPA for residential areas, such as that in the vicinity of the facility. As such, the exposure estimates and levels of significant are likely to be stricter than those that may come in the future from EPA regarding TENORM. Question 2: The total release of radioactivity to the residential environment in Christmas Valley through the deaeration of SUT#3 well water is enormous and the radioisotope released, radon222, is extremely toxic. o Based on pilot tests it is clear that the proposed deaerator will remove 604 pCilL from the 1400gpm of extracted well water. This will result in the release of 1.68 Curies per year into a residential neighborhood in Christmas Valley. o This is an enormous amount of radioactive material. It exceeds twice the total curies released under continuous operation in 2004 by the 1100 MWe Diablo Canyon Unit 1 nuclear powerplant (0.84 curies in continuous gaseous release in 2004). It is over half (55%) of all gaseous releases made by the same unit .in that year (3.05 curies). Diablo Canyon Unit 1 is one of the largest nuclear powerplants in the United States. o At Diablo Canyon, exclusion areas result in the gaseous radioactive releases being made miles from the nearest residence, not 40 feet as in Christmas Valley o The radioactive toxicity of the Radon222 to be released in Christmas Valley is - 100 times greater than that of Ar41 , Kr85 and Xe 133 which comprised almost all of the Diablo Canyon gaseous releases in 2004 South Tahoe Public Utility District. 1275 Meadow Crest Drive, South Lake Tahoe, CA 96150 Phone 530.544.6474. Facsimile 530.541.0614. www.stoud.us _36_20 (Diablo RemD EDB rotLicenseeReleaseAmts.asD.htm , 10 CFR 20 App B Table2). o If this well were licensed by the Nuclear Regulatory Commission (NRC), offsite exposures to the public could not exceed 0.1 pCi/L were much lower (50 mRem annual exposure...equivalent to about 10 chest X-rays) but more importantly, STPUD would also be required to control emissions such that they are As Low As Reasonably Achievable (ALARA). This last requirement is taken very seriously by the NRC and would require engineering altematives at reasonably higher costs be adopted if they can lower dose. Response: The commenter calculates the amount of radon removed from the water. The amount removed from water (500 pCi/L in the Initial Study) is reduced to 31.2 pCilL in the aerator, and then further reduced to 0.08 by dispersion from the stack. On an annual average basis, the maximum radon concentration emitted from the facility would be 0.0064 pCi/L. The risk assessment procedures used by the EPA take these exposure concentrations, and then consider the duration of exposure. These procedures are the basis for the levels that EPA would require mitigation. As is clear from the analysis, the facility's emission 0.16 percent of the EPAs action level of 4 pCilL and well within measurement uncertainty of radon detection. Therefore, the emission will not have a detectable effect on sites that are already near the EP A action level of 4 pCi/L. Furthermore, the average annual increase in radon concentration from the facility would be 1.6 % of EPAs average nationwide outdoor radon level of 0.4 pCilL. Based on the Radon Map provided in the Initial Study, the Lake Tahoe area is likely to be higher than this national average, and as such the emission is an even smaller percentage. The comparison to Diablo Canyon is not equivalent; the nuclear power plant can emit gamma and beta radiation, which is much more resistant to shielding than the alpha particles emitted by radon. Accordingly, the regulatory framework governing Diablo Canyon differs from that used by EPA to protect residential populations from radon exposure. Question 3: The plume screening study carried out as part of the Initial Study/Negative Declaration may not be adequate to properly model the SUT#3 situation, and does not provide enough information to allow the public to adequately judge their risk. a) One input does not appear consistent with the pilot study and well #3 chemistry. The radon concentration appears incorrect by as much as 20%. b) Sensitivity analyses do not appear to have been performed. The exposures calculated by the model appear to be very sensitive to the height of the receptor (possibly 2 or 3 orders of magnitude). There are a number of residences in close proximity to the well stack that have second stories in which people likely sleep and spend an appreciable fraction of their time with windows open during much of the year. There exposure will be underestimated. c) The model assumes the stack will release a plume at the same temperature as ambient air. During much of the year the well water in the deaerator (with well water at - 47, 48 deg F) will subcool the stack exhaust air relative to ambient air. This would likely result in negative South Tahoe Public Utility District. 1275 Meadow Crest Drive, South Lake Tahoe, CA 96150 Phone 530.544.6474. Facsimile 530.541.0614 · www.stpud.us -3721 buoyancy for the plume, a lower height and increased exposure to local residents. Further there is some indication that the EPA model used was designed primarily for powerplant plumes and may not be appropriate for plumes in which the exhaust air is below ambient air temperatures. d) It is, not clear what analysis was conducted to evaluate models for plumes at high elevations (6300 ft) and for local -Christmas Valley- geographical and meteorological conditions. Strictly from winter observation (when there is smoke in the valley) there appear to be frequent occasions in which there are inversions or some meteorology which traps emissions near the ground. At the emission rate from the stack this might result in 1- 2 mremlhr if such meteorology could expose people to near stack concentrations. A few days of this per year might result in exposures which easily exceed the 15 mRemlyr EPA guidance. e) This program simply calculates average radioactive concentrations. Because of the high radiotoxicity of radon a small concentration can still result in a significant risk. Any analysis should also identify dose to the most affected members of the public. Including a range of outcomes to show what might occur in improbable years with particularly bad weather outcomes (inversions?). Response: The responses are presented according to the letter of the paragraph indicated above. a. The Initial Study used a wider range of measurements than in the pilot study. A change of 20% to the input value would not lead to a different conclusion from the study, based on the very low concentrations calculated. b. The model is widely used and has been extensively validated, including sensitivity analysis. The Initial Study describes the effects of some of the variables, based on this information. c. The dispersion model did not include provision of plume buoyancy, and as noted in the report this leads to a conservative outcome to the model. d. The model makes conservative (worst-case) assumptions in order to provide an upper bound on the maximum concentration that could be emitted. Consideration of more site-specific conditions would lead to lower concentrations. Since the result of the screening level model produced such a minor concentration, the more site-specific modeling was not needed for impact assessment purposes. e. See response to lid"; the more specific modeling was not needed because the bounding-level analysis showed such minor concentrations emitted from the facility.

Response: The District has been using sodium hypochlorite as a disinfectant at drinking water wells since 1989. Since 1989, sodium hypochlorite has been safely and properly used at the South Upper Truckee site without incident. Sodium hypochlorite for this project will be contained in a double-walled 400-gallon tank within the chemical room. Any spills from the tank would be contained within the building and directed to the floor drain to the District sanitary sewer. The District has been using diesel fuel to power emergency stand-by generators at six (6) drinking water well facilities through the South Tahoe area, including the South Upper Truckee site. Diesel fuel has been used at the South Upper Truckee site since installation of the emergency power generator in 1993. Diesel fuel for this project would be contained within a 200 gallon double-walled belly tank underlying the generator within the building. Spill buckets would be used to clean-up spills from the tank. The proposed project will not change the use of sodium hypochlorite or diesel fuel at the site. The District has developed a Hazardous Materials Business Plan to be filed with the EI Dorado County Environmental Management Department, prior to construction of the facility. The Hazardous Materials Plan includes a training plan that informs District staff on the proper use of spill clean-up procedures, notification requirements and the proper handling of hazardous materials used at this site. Question 5 Noise: The TRPA guidance for this project should be "not exceed August....1982....levels" or 50dB whichever is most limiting. (Note 1982 levels would not be greater than ambient levels today, 2007 and therefore ambient 2007 levels should be able to be used as a limit when these are less than 50db). I would suspect that at many times of day and year, Christmas Valley will see ambient sound levels, absent the pumping and water treatment facility, less than 50 dB. Just because a rural area may have a low ambient background noise level should not provide the right for a company to create a noisier environment up to the TRPA 50 db limits. Fans are inherently noisy and difficult to silence. Two 25 HP, 3600 RPM, 1500cfm fans operating 24 hrs/day 365 days a year likely create a discernable background noise even with good silencing especially during quiet periods of the day (early morning hours) and particularly quiet times of the year. If this project is actually constructed, which it should not be, then the standard should be no discern able noise level at any time of day or year above ambient conditions. This should be an easy standard to measure. STPUD should agree to contract with a knowledgeable noise engineering organization to develop a testing procedure to measure instantaneous ambient noise levels at the quietest periods of time both daily and during the course of a year and during those periods to have STPUD cycle the treatmenUpump facility on and off while instantaneous measurements are taken.

Response: The District appreciates and values the serenity of this area and will take all reasonable steps to maintain this condition. Facilities and equipment will be installed as necessary to meet the 50db community noise limitation. In addition, the District intends to install additional or expanded features as necessary to control noise and particular frequencies and modulations that may present a nuisance to the neighborhood. Noise control was a major issue during the District's design process that resulted in the following sound dampening features: 1. All mechanical equipment will be housed within a concrete block building 2. A submersible pump and motor set in the production well; 3. A universal inlet silencer and sound attenuation wrap will be installed on the aeration blower and motor; 4. Sound dampening board will be installed on the interior ceiling and walls of the mechanical building; 5. A noise silencer will be placed on the air inlet; and 6. The air inlet will be directed toward the west, away from neighboring residences. Although we believe these systems will provide the necessary noise control, additional equipment and/or features will be installed if necessary. The District is open to having the TRPA assist or consult in the completion of a sound survey. Question 6 C02: Finally, I find it very interesting that we are at a time in this world when many progressive states, cities and corporations are doing everything they can to create programs to minimize adding greenhouse gases to the environment. A major theme in green house gas mitigation strategies has been to sequester carbon back into the ground. For many industrial facilities this will come at a very high cost. South Lake Tahoe, an environmentally aware community where I assume support for Global Warming mitigation has almost unanimous support, is going to pick an option for treating its drinking water in which it takes already sequestered carbon (C02) in groundwater, strip it out of the water and release it to the air. Is this really what we want to do? Response: The District retained a qualified water treatment specialist and chemical engineer to evaluate corrosion control treatment options in compliance with CCR 9 64683(a). Corrosion control options under consideration included use of chemical additives, such as silicate or phosphate inhibitors and pH adjustment using aeration andlor chemical addition. Use of phosphate inhibitors was ruled out for cost, as well as environmental reasons, as phosphate addition has the potential to indirectly contribute to eutrophication of Lake Tahoe. Silicate inhibitors were also ruled out due to cost, as well as potentially detrimental affects to finished water quality. With regard to pH adjustment, South Tahoe Public Utility District. 1275 Meadow Crest Drive, South Lake Tahoe, CA 96150 Phone 530.544.6474.

For these and other reasons, the findings and treatment recommendation for this facility was to use aeration by mechanical means, with minimal addition of chemical additive, if necessary. The District believes that this is the most appropriate and cost effective corrosion control treatment alternative for the South Upper Truckee Well No.3. The Department of Health Services carefully reviewed the Corrosion Control Report and approved the recommended treatment option. South Tahoe Public Utility District. 1275 Meadow Crest Drive.

Three weeks do not allow adequate time for the layman to fully understand and analyze the facts presented and consult experts. Please allow additional time so that we can more adequately understand this project which impacts our neighborhood, the air we breathe, and our quality of life. We absolutely must obtain outside qualified evaluations to fully address our concerns." Response: The project is being proceeding in compliance with the reporting. notification, and review requirements as prescribed by the California Environmental Quality Act (CEQA). In addition. the District has provided extra opportunities for public review and comment, as detailed in the following paragraph. The need for this project was initially discussed during a Board Workshop convened in October 2005. In December 2005, the Board authorized staff to request proposals from consulting engineering firms to conduct a Corrosion Control Study (CCS) for the South Upper Truckee Well No.3, in accordance with California Safe Drinking Water Act Requirements. In February 2006, the Board approved staff recommendation to select Kennedy/Jenks Consultants (K1JC) to conduct Phase I of the study. In June 2007, the Board approved Phase" of the CCS was approved by the Board. In March 2007, Kennedy Jenks Consultants (K1JC) provided a 20-minute presentation describing the purpose, methods and major findings from the Corrosion Control Study. In April 2007, the District conducted a neighborhood meeting that discussed plans for the construction of the CCS water treatment facility. At each of these meetings. the public has had an opportunity to provide input on this project. In addition to public review and comment, numerous public agencies, including the TRPA. EI Dorado County, and the California Department of Health Services, have been involved with the project. These agencies have experts in various fields that are able to provide unique expertise during the review and comment period as an independent agent for the average homeowner or layperson. Comment 2: "According to your report regarding noise of the intended well. "...the noise leaving the building will be through the air inlet...directed toward the west away from, neighboring residences."

The District is open to having the TRPA assist or consult in the completion of a sound survey. Comment 3: "The release of carbon dioxide and radon from the proposed chimney and air outlet are of great concern. We have read reports which indicate that this situation should be much more closely examined and evaluated before any plans are finalized. We are most concerned about our own health as well as that of our neighbors. We question your statements that these emissions pose "...no significant risk to public health. n At the very least, more research is needed to accurately evaluate the short and long-term impact of these emissions into our mountain and neighborhood environment." Response: CO2 and radon are naturally occurring elements present in the groundwater at the SUT well. The levels of these constituents are below limitations set by the California Department of Health Services (DHS) and do not present a health concern and do not require removal or treatment. The DHS is responsible for the safety of the water we drink as well as the safety of any water treatment processes including the safety of the release of C02 and radon into the air. The low levels of C02 and radon in the groundwater result in low, insignificant levels released into the air by the aeration system. Environmental impacts to the release of radon from the proposed project are addressed in the draftlS/ND, Appendix E, Section 4.0 - EXPOSURE ASSESSMENT. Findings from the exposure assessment shows that average ambient concentration of radon gas in zone of maximum impact (that is 62 feet from the outlet chimney at a height of 59 inches above surrounding ground elevation) would be equivalent to a 1.6% of EPA's average nationwide outdoor radon level (0.4 pCi/L). The annual average radon emission concentration from the site will be less than 0.0064 pCi/L. This is 0.16 percent of the EPAs action level of 4 pC ilL and well within measurement uncertainty of radon detection. Therefore, the emission will not have a detectable effect on ambient radon levels. Comment 4: "The industrial storage of hazardous chemicals and diesel fuel in a residential area is unacceptable.

The District has completed a draft of a Hazardous Materials Business Plan in compliance with and as required by the EI Dorado County Environmental Management Department. This plan includes information on two materials, sodium hypochlorite (similar to household bleach) and diesel fuel, that meet the reporting requirements set by the County. The District's draft plan includes general materials information, estimated volume of consumption, materials handling and storage procedures, and emergency contacts, response procedures and precautions. This is basic information that the County requires to assess potential hazards and to make sure that the necessary procedures and precautions are in place before the facility goes online. The District has been using sodium hypochlorite as a disinfectant at drinking water wells since 1989. Sodium hypochlorite has been used atthe South Upper Truckee site without incident since 1989. The sodium hypochlorite will be contained in a double- walled 400-gallon tank within the chemical room.

(ENTRIX) to: 1) complete an ambient noise monitoring survey; and 2) Conduct a two-year outdoor air sampling program for radon monitoring at the South Upper Truckee site, in the estimated amounts of $10,000 and $20,000, respectively. DISCUSSION: During the June 21, 2007 Public Meeting concerning the Initial Study and Negative Declaration of Environmental Impact for the South Upper Truckee Well Controls Building and Treatment Facility Project, written comments were received regarding potential long-term noise and radon emission environmental health and safety impacts from the project. In consideration of these comments, District staff requested that ENTRIX prepare two cost proposals. The first proposal is to conduct an ambient noise monitoring survey at the South Upper Truckee site. Information from this noise survey will be used as a baseline to assess potential noise impacts from operation of the proposed treatment facility. The second proposal is to develop a sampling program for outdoor air monitoring of radon at the South Upper Truckee site. The sampling program would be used to monitor background radon concentrations before and after operation of the treatment facility to determine any increase above background levels. District staff believes that the project without mitigation has a less than significant environmental impact. The monitoring programs are being implemented in response to the neighborhood concerns and direction of the Board. Results from the baseline noise monitoring and the radon monitoring program will be provided to the community through a stakeholders group being established between District staff and concerned neighbors. -51- Bergsohn July 5, 2007 Page 2 SCHEDULE: July 2007 - July 2009 COSTS: Ambient Noise Monitoring: $10,000 (estimated); Radon Monitoring Program: $20,000 (estimated); ACCOUNT NO: 2029-8463/RWSUTR BUDGETED AMOUNT REMAINING: $2,135,011 ATTACHMENTS: Proposal for Ambient Noise Monitoring, June 27,2007; Proposal for Radon Air Monitoring, June 27,2007.

(ENTRIX) has prepared this proposal to conduct an ambient noise survey at the proposed South Upper Truckee Well Controls Building & Corrosion Control Treatment Facility in response to your request dated June 22,2007. The property is located at 3140 Egret Way in EI Dorado County, California. The objective of the scope of work is to characterize ambient noise conditions before and after construction of the proposed water treatment facility property. The scope of work involves project management, conducting two ambient noise surveys (one before and one after construction), and preparing a report summarizing the noise survey methods and results. The scope of work is described in further detail below. The total cost for the proposed scope of work is $10,000 as shown in the attached table Task 1 -Project Management The Project Manager will be responsible for ENTRIX's adherence to project schedules, project coordination, maintaining project documentation, and management of technical, financial, and administrative aspects of the project. The Project Manager is the primary liaison between STPUD and the ENTRIX project team. Task 2 - Ambient Noise Survey This task involves conducting two ambient noise surveys. The first survey will be conducted prior to construction (estimated date of July 15, 2007) of the proposed facility to characterize current ambient noise conditions and the second survey will be conducted following construction (estimated date of June 30, 2008) to characterize post-project ambient noise conditions. The noise data will be collected f~om one location along the property line. It is assumed that the selectecllocation will be secure so the noise level meter can be safely left unattended. The noise surveys will be conducted over a 25-hour period and will involve continuous monitoring with data collected every 5 minutes to comply with Tahoe Regional Planning Agency standards. The noise data will be collected using a Type 1 integrated sound level meter which meets ANSI S1.41983, IEC 651-1979, and IEC 804-1985 standards for precision. The meter wilrbe calibrated before and after each noise study. The microphone will be fitted with a windscreen and bird spikes to reduce wind and bird noise and will be -55- E N T R I X Since 1984 - Environmental Excellence ENTRIX, Inc 1048 Ski Run Boulevard South lake Tahoe. Califomia 96150 (530) 542-0201 (530) 542-4401 fax June 27,2007 Mr. Ivo Bergsohn, PG, CHg South Tahoe Public Utility District 1275 Meadow Crest Drive South Lake Tahoe, CA 96150 Dear Ivo: ENTRIX, Inc. (ENTRIX) has prepared this proposal for the South Tahoe Public Utility District (District) to monitor background radon concentrations in the vicinity of its proposed South Upper Truckee Well Controls Building & Corrosion Control Treatment Facility ahd continue to monitor after startup in order to determine any elevation in the radon concentration above the backgrOUnd in response to your request dated June 22, 2007. Radon is a colorless, odorless, chemically inert, naturally occurring, radioactive gas which is found at varying concentrations in outdoor air. It is formed by the decay of radium, from an ultimate parent of uranium-238. Uranium and radium are present at low concentrations in many soils, rocks and in materials, including building materials. The property is located at 3140 Egret Way in EI Dorado County, California. The objectives of the scope of work are as follows: · Characterize the background levels of outdoor radon in the vicinity of the new well house. · Characterize levels of radon in the same locations during operation of the new aeration treatment unit. The scope of work involves project management, conducting quarterly radon monitoring for 2 years (one before and one after construction), reporting results to the District annually, and preparing a report summarizing the radon monitoring methods and results. The scope of work, including the methods and quality controVquality assurance (QA/QC Plan), is described in further detail below. The total cost for the proposed scope of work is $20,000, as shown in the attached table. The concentration of radon in outdoor air is typically 0.1 to 0.6 pCilL; the EPA provides a nationwide average of 0.4 pCiIL. The EPA has also established an action fevel for radon in indoor air of 4.0 pCilL. There is considerable variability in outdoor levels owing to meteorological and geological factors. Factors such as the strength of the source, the emanation rates, temperature, humidity and moisture, winds and the distance from the source all have an impact on the radon level. Public input to the District's project plan indicates concern that the nationwide average does not adequately characterize local conditions. There is also concern that operation of the aeration unit will lead to an increase in the levels of outdoor radon. -56- Since 1984 - Environmental Excellence Task 1: Project Management and Public Meetings The Project Manager will be responsible for adherence to project schedules, project coordination, maintaining project documentation, and management of technical, financial, and administrative aspects of the project. The Project Manager is the primary contact between STPUD and the ENTRIX project team. ENTRIX staff, along with District staff, will hold two meetings with representatives from the District and the Egret Way Neighborhood Committee. An ENTRIX Staff Engineer will be present at the first meeting to discuss methods being considered for the air sampling protocol prior to the construction of the facility. The second meeting will be used to address the Egret Way Neighborhood Committee's questions after the draft protocol is completed. This meeting will be attended by both the Staff Engineer and Technical Lead and Principal in Charge. A QAlQC Plan will be in place to provide procedures to obtain representative data that can be used to meet the project goals. In general, quality and representation of the data are assured by adherence to formalized and standardized field and laboratory procedures performed by trained, qualified personnel. The QA Director for the project is responsible for implementing the QNQC Plan to ensure that sampling and analysis procedures are properly followed. The QA Director coordinates the necessary report preparation, reviews, and also provides QA audits. For this project, the QA Director and Project Manager roles are combined. A Health and Safety Officer will implement the Health and Safety Plan (HSP), documenting all health and safety related activities, and ensuring that health and safety equipment is calibrated and maintained. The existing HSP will be present at all times on the site. Task 2: Outdoor Radon Air Sampling Long-term radon tests are the most reliable measurements of average levels, because they capture a range of conditions. Alpha-track detection will be used because It has greater sensitivity than carbon absorbers that are typically used for short-term indoor radon measurements. The alpha track detector contains a film that records the impacts (tracks) of alpha particles produced by the decay of radon and its decay byproduct, polonium. At the end of the radon gas test period, the radon testing kit is sent to a certified laboratory, where the alpha tracks on the film are counted and the radon concentration is computed. It should be noted that the alpha-track method, though providing greater sensitivity than carbon absorbers, is still a method most typically applied in indoor air quality measurement. Meteorological data will be summarized during the monitoring period for use in data interpretation. In addition, the local geology will be inspected and described during initial deployment of the sampling units. Radon monitoring will occur at five locations in the area. Screening-level air dispersion modeling predicted the highest radon levels 62 feet from the discharge stack. The monitors will be installed between 60 and 75 feet from the discharge stack. The sensors are small and readily deployed by mounting in an elevated enclosure. The elevation is determined by the nature of the study, the nature of the surrounding terrain and -57- Since 1984 - Enwonmentai Excel!ence is collected. The Chain-of-Custody will accompany the sample through all transportation until it is received by the laboratory, where it is filed. Whenever a sample is transferred from one party to another, both parties sign and date the Chain-of-Custody at the time of transfer. Task 3: Data Analysis and Reporting Two annual reports will be prepared for the monitoring. Both reports will summarize monitoring objectives, methods, and results. The first report will focus on establishing the range of measured natural radon variation. Contributors to analytical uncertainty will be described, as will natural factors that lead to variation. The second report will focus on discerning detectable variation from the background established during the first year. If levels approaching EPA action levels are determined, then a range of contingency measures will be considered, based upon the results and the likely causes. Contingency measures can include the following: . More detailed measurements of radon concentration . Measurements of indoor air concentrations . Enhanced plume dispersion . Modification of aeration . Cessation of aeration The second report will also be comprehensive, and incorporate the results of the first year's monitoring. Data from the analytical laboratory will be reviewed by internal laboratory management before being submitted to the Project ManagerlQA Director. Analytical data from the laboratory must include the data report, and all related QAlQC data. The Project Manager/QA Director will be responSible for evaluation of the data, including tabulating all laboratory data and completing a QA/QC review. During the course of the project it will be the responsibility of the Project Manager to ensure that all of the specified sampling procedures are followed and that data meet prescribed acceptance criteria. The field and analytical procedures will be reviewed if QNQC problems or deficiencies requiring corrective action occur. If a problem is discovered, prompt and prescribed action will be taken to correct the problem. Corrective action may be initiated based upon QC data or audit results. The Project Manager and QA Director will rely on written reports and memoranda documenting data assessment activities, audits, nonconformance, and corrective actions to verify that QA requirements are being met. QAlQC. activities will be documented. All information received from an outside source or developed during the project will be stored in project files. The Project Manager will identify which field documents will be designated as QA records for the project file. The Project Manager will also ensure that QA records are properly stored and retrievable upon completion of the project.

DISCUSSION: The Angora Fire, which has been burning since Sunday afternoon, June 24, 2007, has resulted in moderate to major damage of over 220 homes thus far in the North Upper Truckee, Tahoe Paradise, and Angora Highlands neighborhoods. Each of these affected lots has a water connection and a sewer connection which need to be abandoned in order to protect the remainder of the system. Also, there are a hundred or more fire hydrants in the fire area that may have been damaged by the fire or during evacuation and fire-fighting operations. These hydrants need to be tested and, if necessary, replaced. Time is of the essence in performing these repairs for a number of reasons. First, un- repaired leaks at damaged and destroyed properties can affect the water pressure available on the water system. Staff has been working diligently to turn off water at these lots, but additional work is anticipated to secure the water services at these lots until they are needed again. Second, the foundations of destroyed structures pool water and debris and funnel it into open sewer laterals, increasing the potential for blockage of the sewer system and/or upset of the wastewater treatment plant. Last, fire hydrants in the affected area need to remain operational, as the risk for flare-ups and spot-fires in this area will remain high for some time into the future. -61- Ryan July 5, 2007 Page 2 Staff proposes to contract with one or more local contractors (to be determined) to start the week of July 9 abandoning water and sewer connections and testing and replacing fire hydrants. Work will be performed on a time and materials basis, since the amount of effort required may vary significantly from lot to lot and from hydrant to hydrant. Staff expects the work to cost at least $500,000; a more detailed estimate has not been prepared at this time. This project is not in the budget because it was not anticipated. Allocated funds will be split between the water and the sewer budgets, as needed. Staff will provide the Board with bi~weekly updates of project progress and the need for additional funds. The State of California, Office of Emergency Services has indicated that these costs will be eligible for disaster fund reimbursement. The major water system structures in this area (water tanks and booster stations) appear to have sustained little damage so far, but will need to be assessed more fully before allocating funds for their repair, and so are not included in this allocation request.
