Introduction RDNO is pleased to present the 2011-2012 Annual Water Quality Report for the Silver Star Water Utility (SSW). This report provides information regarding the water quality and status of this system. This report summarizes the operations and water quality results for the SSW for the years 2011 and 2012, as required by the British Columbia Drinking Water Protection Act. The report addresses the Silver Star Water System Drinking Water Quality Improvement Program 2010 Conditions on Permit (COP) provided in a letter by Mr. Bryn, DWO (DWO) for Interior Health (IH) dated August 26, 2010. 2. Background The SSW system was constructed in the 1980s and was operated as a private utility owned by Silver Star Mountain Resort Ltd until 1992 when it became a function of the Regional District of North Okanagan (RDNO). The RDNO Utilities Engineer is responsible for the operation and management with oversight provided by the General Manager of Engineering and the RDNO Board of Directors. RDNO employs a contract operator to complete day to day operation and maintenance tasks, who is also required by contract to respond 24/7 to emergencies or to have a back up available to respond. 3. Water System The SSW provides potable water to 15 commercial and 371 residential connections. customers are metered. All The following provides a summary of the SSW facility with an overview of the facility provided in Appendix A: 1 • The source water for the utility is from both surface water and groundwater. There are currently seven operational bedrock wells. Surface water is collected and stored in the Paradise Lake Reservoir. • Vance Creek Reservoir was filled in the spring of 2011, however, in June of 2012, it was determined that the reservoir liner was leaking from a damaged gate. The reservoir was drained in July 2012 and the gate and liner repaired in September-October of 2012. Hence, Vance Creek Reservoir was not used in the 2012 winter season and will be filled during the 2013 freshet. • All water from the groundwater and surface water sources 1 is directed to the Mid Tee Reservoir (Mid Tee) where it is chlorinated and directed to the Mid Tee for storage. The Mid Tee is a ‘closed’ reservoir. The Mid Tee facility was upgraded in the fall of 2011 and spring of 2012. The upgrade included the installation of UV treatment. with the exception of Well 4. Well 4 was not used in 2011-2013 and will be designated as a backup well. 1 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report • Water is supplied to the majority of residents and commercial customers via gravity to the distribution system. • The Ridge Booster Station is located at the bottom of the Ridge Subdivision where water is pumped up to the Ridge Reservoir and distributed to Ridge Subdivision residents via gravity. • The Attridge Reservoir is a small open reservoir located upslope of the Mid Tee facility. It is the original storage reservoir for Silver Star Village built circa 1980 and currently not used as a water supply. In 2011 and 2012, Zee Marcolin, RDNO Utilities Engineer, was responsible for operations and maintenance for all of the small water utilities that are within the RDNO’s jurisdiction, including the SSW facility. As of February 2013, James de Pfyffer, RDNO Small Utilities Manager is responsible for operations and maintenance of SSW. The RDNO Water Quality Manager, Renee Clark, is responsible for the water quality monitoring program for all RDNO water utilities. The following sections correspond to the Conditions on Permit in the 2010 COP letter: 4. Provide a Source Protection Plan For Each Water Source (Condition 1) The following reports provide the basis of the Groundwater Protection Plan and the Source Water Protection Plan for the SSW: • Golder Associates Ltd (Golder). April 18, 2008. Initial Phases in the Development of a Groundwater Protection Plan for Silver Star Resort Area. (File #07-1440-0092). Prepared for RDNO. • True Consulting Group (True). August 2011. Source Water Assessment and Groundwater Protection Plan, Silver Star Water Utility. Prepared for RDNO. Both these reports are available on the RDNO website (http://www.rdno.ca/) under: Services → Engineering → Water → Community Water Utilities → Silver Star Water Utility. A hardcopy will be provided to IH DWO with the submission of this report. Golder completed the initial phase of the Groundwater Protection Plan (GWP) in 2008. True was retained to prepare a Source Water Assessment (SWA) and complete the GWP. The SWA project was initiated in September 2010 and included input from a Technical Advisory Committee (TAC). The TAC consisted of RDNO staff, SSW DWO, Silver Star Ski Resort Staff, Provincial Staff and Local Interest Groups. The SWA Final Report was completed on August 31, 2011. As the SSW is within a Controlled Recreational Area (CRA), only low and moderate risks were identified. Appendix B provides a summary of the recommendations from the GWP and the SWA the progress on the recommendations and is the basis of the Assessment Response Plan. 2 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report 5. Provide a Certified Operator To Operate The System (Condition 2) The RDNO contracts Aberdeen Electric Ltd. to operate and maintain the SSW system. Warren McKim of Aberdeen Electric Ltd. is the Chief Operator for the SSW drinking water system and is also responsible for 24 hour – 7 days a week of emergency response assistance when required. The operator schedule is to complete site visits a minimum of five (5) per week during the peak winter ski season and a minimum of three (3) site visits per week during the off seasons (spring, summer & fall). The operator also has access to SCADA for checks from his office between site visits. The Silver Star Water Distribution System is certified through the Environmental Operator Certification Program (EOCP) as a Water Distribution II facility (EOCP # 382). The Chief Operator, Warren McKim (EOCP #1336) has certifications for Water Distribution II, Municipal Wastewater Treatment II and Wastewater Collection I. The overall water system operations, maintenance and infrastructure improvements is managed by Zee Marcolin, P.Eng., Utilities Engineer and Dale McTaggart, P.Eng., General Manager Engineering. 6. Operate According To Your Water Quality Monitoring Program (Condition 3) The goal of treatment for the SSW is to prevent and control the presence of pathogenic microorganisms within the distribution system. The RDNO manages the system to have a minimum free chlorine residual of 0.2 mg/L at the ends of the distribution lines (or at the “last customer”). The objectives of the distribution water quality monitoring program is to provide sufficient monitoring to ensure that the minimum chlorine residual is maintained and to have the operator respond if the minimum is not maintained. The following section provides information about the microbial sampling programs. Chlorine monitoring is provided in Section 9 below. 6.1. Laboratory Samples – Microbial and other Parameters The water quality monitoring for SSW is based on the requirements of the Drinking Water Protection Regulation (DWPR) Schedules A and B, the Guidelines for Canadian Drinking Water Quality (CDWQ) and British Columbia Approved Water Quality Guidelines (BCAWQ). The Water Sampling Program for SSW was reviewed in February of 2012. According to the DWPR, the required sampling frequency of 11 per month was based on the estimated pillow count of 10,562 for 2010 / 2011. The microbial sampling frequency completed at Silver Star is 20 samples a month (5 per week) of the treated water. This is to accommodate the system configuration as it is spread out with “last customers” at two distinct locations. The sampling locations are provided in the SSW system overview figure provided in Appendix A. 3 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report The following provides the rational for each sampling site: • Mid Tee – mid way within Mid Tee Reservoirs – after chlorine injection and UV treatment (although before full contact time through Mid Tee Reservoir has been achieved) • Pinnacles – represents the first customer in the Village • Fire Hall – provides a good representation of the typical village chlorine levels in the Village • Grandview – “last customer” on The Knoll subdivision • Maintenance Shop - “last customer” on the west end of the system • Same Sunn Hostel – backup site if Pinnacles not available The Sampling Program and Schedules for 2012 and 2013 are provided in Appendix D. Also included in the parameter list is weekly raw Paradise Lake source water when in use during the winter ski season, annual comprehensive water sampling of all sources (Paradise Lake and the operational wells), quarterly Trihalomethanes (THMs) and quarterly selenium within Well 2. The system operator collects weekly bacterial samples. The results are sent to IH and RDNO and uploaded to WaterTrax, a third party online database that RDNO utilizes to store lab data for all RDNO water utilities. WaterTrax sends automatic alerts to RDNO water quality staff and the Utilities Engineer for any results that are out of compliance with standards. Summaries of the microbial sampling for 2011 and 2012 are provided in Appendix D. There were no microbial positives in the treated water supply at Silver Star in 2011 or 2012. A summary of the historic raw water comprehensive samples taken from the all Silver Star water sources is provided in Appendix E. 7. Cross Connection Control Program (Condition 4) The RDNO hired a full time Demand Side Management / Cross Connection Control Coordinator (now titled Water Sustainability Coordinator) in 2011 and a part-time Cross Connection Control Officer (CCCO) in 2012. These staff members have been directed to develop a Cross Connection Control Program (CCCP) for the water utilities owned by RDNO, including SSW. In 2011 and 2012, CCCP staff were primarily focused on updating the CCCP database and increasing annual testing compliance of existing Backflow Prevention Devices (BFD). The work plan for 2013 includes the following initiatives: • Complete assessments on the high hazard facilities at Silver Star, and • Updating the Cross Connection Control Bylaw. The Cross Connection Control Bylaw currently only covers the Greater Vernon Water Utility. The update will include developing the Cross Connection Control Bylaw as a RDNO wide bylaw and incorporating all water utilities owned by the RDNO. 4 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report In 2012, a Cross Connection Assessment Form was developed and rolled out to the RDNO Building Department (Appendix F). This assessment will be completed for all development and permit applications processed through the RDNO Building Department and include permits issued at Silver Star. Also developed in 2012, was the Backflow Prevention Device (BFD) Tags (Appendix G). These tags are distributed to certified testers in Vernon and area with instructions to attach the tags to BFDs to assist in tracking testing. 8. Provide a Turbidity monitoring Program (Condition 5) Continuous online turbidity monitoring is carried out with a Supervisory Control and Data Acquisition (SCADA) system at: 1. Mid Tee facility for all blended water entering the facility, and 2. Raw water at Paradise Lake Pump House. This data can be accessed real-time using the SCADA system. The alarm set points for turbidity were recently checked and were noted to be high due to an issue that occurred during the Mid Tee construction. The set were changed to 1.0 NTU at the Mid Tee facility and if the turbidity exceeds 1.0 NTU, IH would be notified as per the RDNO notification checklist/procedure – operator provided in Appendix G of the SSW Emergency Response Plan (ERP). (Copy of the ERP will be provided to IH DWO with the submission of this report.) Online raw water Turbidity results are provided in Appendix H for: • January and February 2011, and • February to December 2012 The SSW computer located in the Mid Tee facility failed in February 2011 and a temporary computer was installed until February 2012 when the permanent replacement was installed. During the writing of this report, the data from the temporary computer was unavailable for review but the RDNO IT Department were attempting to retrieve the data. The Operator and the RDNO Utilities Engineer who monitor the SSW SCADA system, do not recall any turbidity concerns. No incident reports are noted during this timeframe regarding increased turbidity while the temporary computer was installed (protocol requires that all Water Quality events be recorded in the incident tracking database). The turbidity at the Mid Tee facility has been consistently well below 1 NTU. During the 2011 – 2012 timeframes provided, turbidity spiked to approximately 1 NTU four times, however each reading was a single reading and likely due to a pump start. The raw water at Paradise Lake undergoes short term turbidity spikes above 1 NTU, likely due to wind or pump start events. No turbidity events during the 2011 – 2012 timeframes provided occurred longer than 24 hours for the raw water at Paradise Lake. The highest reading was 4.2 NTU (the turbidity during this event ranged from 1.1 NTU to 4.2 NTU and lasted 30 minutes). 5 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report The longest turbidity event was 12 hours (averaged turbidity measured every 4 hours) on Paradise Lake and ranged from just above 1.0 NTU to a maximum of 2.6 NTU. 9. Provide Continuous Online Monitoring of the Water Disinfection Process (Condition 6) 9.1. Chlorine Disinfection The following provides a summary of the chlorine dosing protocol at SSW: • The Mid Tee is dosed at between 1.7 to 2.1 mg/L (ppm) – This dosing rate provides typical resultant distribution residuals of: o 1.6 to 1.7 ppm at the Pinnacles –“first customer” o 1.3 ppm at The Ridge during the winter (dose at 1.0 ppm during off-season) o 0.8 to 1.2 ppm at the Maintenance Building – “last customer” o 1.2 ppm at the Grandview on The Knoll – “last customer” RDNO received numerous customer complaints due to elevated chlorine levels in the Silver Star Village (Village) area. These levels were required to ensure adequate chlorine at The Ridge Subdivision. In July 2012, a chlorine injection site was added at the Ridge Booster Station to allow a reduction in the chlorine dosing level at the Mid Tee. Prior to The Ridge chlorine injection site, the Mid Tee was dosed at between 2.0 to 2.5 ppm resulting in chlorine levels of 1.9 to 2.3 ppm in the Village. There have been no customer complaints since the chlorine dosing has changed. 9.2. Online Chlorine Monitoring SSW has three online Chlorine residual analysers at the following locations: 1. Mid Tee – collects the sample 10 m after the chlorine injection within the Mid Tee facility 2. Mid Tee Reservoir in Cell 4 – collects the sample from within the 1st cell of the Mid Tee Reservoir or “Cell 4” 3. Ridge Booster Station – a chlorine injection site was installed in the Ridge Booster Station in July of 2012 to lower chlorine residuals within the Village. Dosing is not required during the winter as there is sufficient flow to sustain adequate residuals, however, a dosing rate of approximately 1.0 ppm is required during the off-season. The Operator completes chlorine residual sampling from within the distribution system with a handheld chlorine meter and records the results on an excel spreadsheet on each site visit (five (5) per week during winter, three (3) per week during off season). 6 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report The chlorine alarms for the Mid Tee chlorine analyzers are as follows: • Reservoir chlorine residual ⇒ High 4.5 mg/l, 15s delay ⇒ Low 0.5 mg/l, 5 minute (300s) delay • Mid Tee chlorine residual ⇒ High 4.5mg/l, 15s delay ⇒ Low 0.5 mg/l, 10 minute (600s) delay A summary of the 2011-2012 chlorine residuals is provided in Appendix I. 9.3. Contact Time Contact time for SSW was reviewed in the following letter report: • Agua Consulting Inc. (Agua) July 8, 2008. RE: Silver Star Mountain Water System Vance Creek Reservoir and Well 13 Disinfection Effectiveness Assessment. Prepared for RDNO. A hardcopy will be provided to the IH DWO with the submission of this report. The report is also provided on the SSW page on the RDNO website (http://www.rdno.ca/). The Agua report examines the contact time with chlorination only to full build out of 22,500 pillows 2. The report concludes that with chlorination alone, 180 min-mg/L is required for 3 log inactivation of Giardia, which is achieved until the build out is equivalent to 14,900 pillows. The current pillow units developed at SSW is 10,562. The Agua report provides for a contact time of 215 min-mg/L for 12,500 pillows. Hence, 3 log inactivation of Giardia is achieved at SSW with chlorination alone. SSW recently installed UV to achieve the IH 43210 objective of dual disinfection, which provides a 2 log inactivation credit for Giardia. Based on the winter peak parameters and the requirement of 1 log inactivation of Giardia with UV, the contact time requirements is 58 minmg/L through the Mid Tee Reservoir. Agua calculates that at this contact time, a total development build out of 25,000 pillow units can be accommodated before additional disinfection efforts are required. 10. Provide Long Term Plans for Source, Treatment and Distribution System Improvements taking into Account the Goal of 43210 Treatment Objectives (Condition 7) The following section provides a summary of progress on achieving the IH 43210 Objectives and Sections 10.2 addressed progress on fulfilment of filtration deferral criteria. 2 The Agua report refers to “Bed Units” which are referred to and are equivalent to “pillow units” at SSW. 7 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report 10.1. Progress on SSW achieving IH 43210 Objectives The following provides an update on the process of achieving IH 43210 Objectives using the contact time values provided in the Aqua report for 12,500 3 pillow units: • 4 log removal for viruses - SSW uses chlorine to inactivate viruses. Based on peak flows at SSW and water quality parameters, the required contact time for 4-log virus inactivation is 12 min-mg/L, which is well within the contact time of 215 min-mg/L for 12,500 pillows. • 3 log inactivation of protozoa – UV treatment has been in operation since June 2012. UV provides 2 log credit for protozoa inactivation and the remaining 1 log inactivation requirement is 58 min-mg/L, well within the contact time of 215 minmg/L for 12,500 pillows. • 2 treatment barriers – SSW is now disinfection with free chlorine and UV treatment, residual chlorine is also maintained in the distribution system with a minimum objective of 0.2 ppm at the “last customer” with an actual minimum maintained typically at 0.8 to 1.2 ppm at the “last customers”. • 1 NTU maximum turbidity or below – online continuous turbidity monitoring is completed on Paradise Lake and the Strategic Water Plan Update for SSW (True, 2011) completed a statistical analysis for the 2010 turbidity data set as provided in Table 3.0 of the report. The analysis demonstrated that the turbidity at Paradise Lake meets the filtration deferral of: i. Source turbidity before disinfection does not exceed 1 NTU 95% of the time in any 30 day period, and ii. Peak turbidity readings do not exceed 5 NTU for more than two days in a one year period. Turbidity results for 2011 and 2012 provided in Appendix H also meet the criteria. Turbidity will continue to be monitored and will be analyzed for Vance Creek Reservoir, which will be brought online as a potable water source during the winter 2013-2014 season. • 0 bacterial indicators within the water supply – only two raw water samples of the Paradise Lake water were collected and analyzed in 2012 (Appendix E). Both samples had <1 E.coli and one sample had positive Total Coliform. The sampling of the raw water for Paradise Lake has been increased to weekly sampling when in use in anticipation of a filtration deferral application to demonstrate if the raw water meets the criteria of not exceeding 20 CFU/100 ml and/or Total Coliform not exceed 100 CFU/100 ml. RDNO is planning further protozoa sampling as per Section 10.3.4 to demonstrate if the raw water fully meets the filtration deferral requirements for protozoa. 10.2. Mid Tee Facility Upgrades 3 12,500 pillow units are used to provide a conservative estimate for contact time and is above the current pillow unit estimate of 10,562. 8 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report Major upgrades to the Mid Tee facility were completed in 2011 and 2012 that included the installation of UV treatment for the SSW water supply. A number of deficiencies delayed the issuance of substantial completion and some construction difficulties had to be overcome, however, the Mid Tee facility became fully operational as of December 2012. The UV reactors were initially started in January 2011 but treatment was intermittent due to failures with the UVT analyser. The root cause was water quality of source water that caused a film to develop quickly on the UVT analyzer artificially dropping the UVT reading to below 81%, triggering the automatic turn off set point for the UV reactors. RDNO initiated a manual sampling program of UVT monitoring in the RDNO lab and found UVT to range between 94.2% and 100.0% during the time when the reactor UVT was reading below 81% (provided in Appendix J). In June 2012, the UVT analyser was removed by Wedeco representatives and the automatic low UVT reactor shut off trigger was bypassed with a manual UVT reading of 90% entered to allow consistent UV treatment. Weekly UVT samples were collected manually with UVT readings typically between 98% and 100% with the lowest reading of 93.3%. A new UVT analyzer was installed in December 2012 and appears to be working well with the water quality at the SSW. RDNO will continue to confirm the UVT readings manually with weekly UVT readings until April 2013, at which time monthly readings will be completed. 10.3. Filtration Deferral Criteria Both the Water Treatment Study (Agua, 2007) and the Strategic Water Plan Update (True, 2011) have concluded that the SSW is a good candidate for filtration deferral as per the criteria set out by IH. The following provides a summary of the progress on the IH filtration deferral criteria that need to be met: 10.3.1. Watershed Control Program Both a Source Water Assessment and Groundwater Protection Plan have been completed (see Section 1 of this report). A Strategic Water Plan Update was also completed in 2011. All recommendations within the reports have been considered and implemented into Action Plans which are provided in the tables within Appendix B (Source Assessment) and Appendix H (Strategic Water Plan Update). 10.3.2. Planning for Filtration Conceptual planning for filtration has been completed. A treatment study was completed for SSW in 2007 by Agua (provided at the SSW page at rdno.ca, with a hardcopy provided to the IH DWO at submission of this report). Possible technologies identified for future filtration include pressure filtration, cartridge filtration or membrane filtration. If filtration is required, bench testing would be conducted to identify the most appropriate technology. 9 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report The land footprint for future filtration has already been identified, with the conceptual plan provided in Appendix L. Future filtration would occur as an addition to the Mid Tee UV treatment upgrade. 10.3.3. Financial Planning for Filtration Provincial and federal funding would be sought to assist the SSW in the design and construction of filtration if required, however, the full costs of filtration would be allocated to the SSW if no external funding were available. Additional operational costs of filtration would also be included in the operating budget. Future Development Cost Charges collected would be allocated to the construction; however, this fund was full allocated to the Mid Tee facility upgrades to include UV treatment in 2011 and will likely not recover without substantial development at the Village. Filtration upgrades would be funded with long-term borrowing through the MFA program and repayment would be included in the annual utility budget. Rate increases would be used to fund the MFA repayment and build reserves for infrastructure renewal. 10.3.4. Proposed Sampling Program SSW has two surface water reservoirs, Vance Creek Reservoir (Vance) and Paradise Lake Reservoir (Paradise). Vance has not been used as a potable water source as of yet and will be brought online for the peak 2013-2014 winter season. Vance will be used for one season with online and raw water sampling completed and analysed to ensure the source water meets the IH filtration deferral. Paradise will also be available for use in the event that water quality within Vance does not meet water quality standards. If Vance water quality if acceptable, Paradise will be taken offline in the year 2014 to be lined as the reservoir currently experiences unacceptable seepage loses. Paradise will be brought back online for the 2014-2015 winter peak season and at that time, a monthly sampling program for protozoa will be implemented during the peak winter season to assess background Cryptosporidium and Giardia backgrounds in the surface water sources. 11. Emergency Response Plan (Condition 8) A comprehensive update of the SSW Emergency Response Plan (ERP) was completed in 2012. The ERP was finalized on June 30, 2012. Sampling Training and RDNO small utility ERP training for the Operators occurred on December 11, 2012. A hardcopy of the ERP will be provided to the IH DWO upon submission of this report. 12. Provide Monthly Reports and an Annual Summary (Condition 9) 12.1. Monthly Reporting Monthly reports are provided to the IH DWO which includes: 10 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report 12.2. • weekly microbial results (Total Coliforms and E.coli) entered into WaterTrax, • chlorine residuals during microbial sample collection entered into WaterTrax, • daily flow readings from sources, • daily flow readings to Mid Tee Reservoirs and through UV trains, • chlorine residuals collected by the Operator, and • daily contact time calculation sheet for 3 log reduction for Giardia Annual Reporting Appendix M provides a chart of the Daily Water Consumption for SSW from February 2011 to December 2012. The data from January 2011 is missing. The computer was upgraded at this time, likely before the January backup process occurred and the drive from the old computer has since been misplaced. This data will be included once the old drive is found. Appendix N provides a summary of operation incidents that occurred at the SSW for 2011 and 2012 and how each incident was resolved. The three open reservoirs and dams structures (Paradise, Vance and Attridge) are regulated under the BC Dam Safety Regulation and undergo routine inspections and annual dam safety inspections. The Operations, Maintenance and Surveillance Manual was revised in 2011 and updated in 2012 and was submitted with an annual report to the Dam Safety Branch of the BC Ministry of Forests, Lands and Natural Resource Operations. The following provides a list of work and activities completed outside the regular maintenance and operational activities for 2011 and 2012: • January 2011 – Incident Tracking System for RDNO small utilities implemented. • Spring 2011 – During the Vance filling period, daily dam inspections were completed by the operator (from May 24th to June 14th, 2011), with inspections completed every two days until the dam inspections are completed the first week of July, at which the frequency will drop to weekly as required by BC Dam Safety Branch of Ministry of Environment. • Spring 2011 - Annual distribution line flushing and hydrant maintenance. • July 2011 - Dam safety inspections for Paradise .and Vance. • July – September 2011- Locating and exercising curb stops. Customers with inaccessible curb stops were notified to either fix by May 2012 or RDNO would fix and bill them. Most of the customers fixed their own curb stops by 2012 and remaining will be fixed by RDNO in the summer of 2013. • August 2011 – Cleaned Cell 4 of Mid Tee. • October 2011 – Cleaned Cell 2 of Mid Tee and fixed discharge pipe. • February 2012 - Upgrades to the SSW SCADA system include a new computer and upgrading the software. Additional alarms were also installed that include power off for 11 Silver Star Water Utility 2011-2012 Annual Report Silver Star Water Utility 2011-2012 Annual Report key sites, Vance pump house low temperature and commissioning of Vance Creek monitoring equipment. • Spring 2012 - Annual distribution line flushing and hydrant maintenance. • Spring to Fall 2012 – Repairing Vance – the reservoir was filled in freshet 2011, however, based on SCADA data, a leak was detected and reported as a warranty deficiency to SSMR. Upon investigation, the leak was discovered to be caused by a damaged outflow gate to the reservoir. The reservoir was emptied in the July 2012 (in consultation with Ministry of Environment) and the gate and liner repair completed in August and September 2012. • June 2012 – Dam signage and Dam Operation and Surveillance manuals updated. • July 2012 – Cleaning of Cell 1 of Mid Tee. • July 2012 – installation of a secondary chlorine injection system at the Ridge Booster station • July 2012 - Installation of chlorine injection system at Ridge booster station. This will allow a lower dosing rate to occur in the Village (the current residual in the Village varies from 1.6 to 2.0 ppm). The most customer complaints logged in the past couple of years have stemmed from the high chlorine levels in the Village. • September 2012 – IH approval of supplementary ground water (information regarding the application and approval is provided in Appendix O) • September 2012 – Roof overhang installed on Vance Pump house. • October 2012 – Paradise fence replaced with wildlife barrier fence, breaches in Vance fence also repaired. • Fall 2011 – replacement of chlorine system with chlorine puck system and peristaltic pumps 12.3.

Nonetheless, an current operations inspection of Vance and Paradise diversion ditches completed in the fall of 2012 provide inspections identified crossings of the bike trail and noted erosion. SSMR is notified of any of diversion ditches issues and responds promptly. The diversion ditches are inspected weekly when filling and in the fall before snow fall. Paradise Lake fence was rebuilt in the fall of 2012 with a wildlife exclusion fence. November-12 A few areas requiring repair on the Vance fence were also completed in fall of 2012. The fences are inspected by the operator every spring after freshet and will be repaired as required. Already completed SSMR confirms that the tank is a double walled tank. SSMR has a response procedure and a spill kit on site to address any spills in the event of a spill. As part of that procedure, SSMR will contact RDNO in the event of a spill to assess possible risks to the SSW sources. RDNO completed a updating the Emergency Response Plans for all utilities, December-12 including SSWU. Training operator occurred in December 2012 . Additional work completed based on the SSWU WAP Customer complaints of high Installed chlorine booster in the Ridge booster Station to allow reduction of chlorine (obtained through survey chlorine dosing in Village (Ridge is "last customer" and since development is not process of WAP) built out, low flows required higher chlorine levels in entire system to ensure 0.2 ppm at "last customer".
