10 Ministry of the Environment and Climate Change INSPECTION SUMMARY: Introduction The primary focus of this inspection is to confirm compliance with Ministry of the Environment and Climate Change (MOECC) legislation as well as evaluating conformance with ministry drinking water related policies and guidelines during the inspection period. The ministry utilizes a comprehensive, multi-barrier approach in the inspection of water systems that focuses on the source, treatment and distribution components as well as management practices. This drinking water system is subject to the legislative requirements of the Safe Drinking Water Act, 2002 (SDWA) and regulations made therein, including Ontario Regulation 170/03, "Drinking Water Systems" (O.Reg. 170/03). This inspection has been conducted pursuant to Section 81 of the SDWA. This report is based on a "focused" inspection of the system. Although the inspection involved fewer activities than those normally undertaken in a detailed inspection, it contained critical elements required to assess key compliance issues. This system was chosen for a focused inspection because the system's performance met the ministry's criteria, most importantly that there were no deficiencies as identified in O.Reg. 172/03 over the past 3 years. The undertaking of a focused inspection at this drinking water system does not ensure that a similar type of inspection will be conducted at any point in the future. This inspection report does not suggest that all applicable legislation and regulations were evaluated. It remains the responsibility of the owner to ensure compliance with all applicable legislative and regulatory requirements. Documents reviewed in association with this report included, but were not limited to: 1/ Elgin Area Primary Water Supply System Municipal Drinking Water Licence (MDWL) # , Issue Number 5 issued July 07, / Elgin Area Primary Water Supply System Drinking Water Works Permit (DWWP) # , Issue Number 5 issued July 7, / Ministry of the Environment Permit to Take Water (PTTW) # QZM3N issued on February 9, 2012, expiry date, June 30, / Ministry of the Environment Communal Drinking Water dated July 26, 2016, entitled "Elgin Primary Area Water Supply System " inspection date June 13, 2016 This report also includes a review and assessment of compliance and operating practices in relation to the following Acts and Regulations: 1/ Safe Drinking Water Act, 2002; 2/ Drinking Water Systems Regulation, (Ontario Regulation 170/03); 3/ Ontario Drinking-Water Quality Standards (O. Reg. 169/03); 4/ Ontario Water Resources Act, 1990; 5/ Certification of Drinking-Water System Operators and Water Quality Analysts (O. Reg. 128/04). Other operational documents maintained by the owner/operating authority for the period June 1, 2016 through August 31, 2017 were also reviewed in conjunction with this compliance evaluation. The Operating Authority for the above noted inspection period is Ontario Clean Water Agency (OCWA). The physical site inspection was conducted as unannounced on August 23, 2017 Capacity Assessment There was sufficient monitoring of flow as required by the Municipal Drinking Water Licence or Drinking Water Works Permit issued under Part V of the SDWA. The Owner/Operating Authority has ensured that a sufficient number of flow measuring devices have been Report Generated for millerji on 30/11/2017 (dd/mm/yyyy) Page 7 of 20

11 Capacity Assessment installed, maintained and operated to measure the flow rate and daily quantity of water being taken from the source at the intake; conveyed to and through the treatment plant; and the flow rate of treated water supplied to the distribution system. Schedule C Section 2.0 of Municipal Drinking Water Licence (MDWL) # Issue Number 5 issued for the Elgin Area Primary Water Supply System (EAPWSS) requires the drinking water system to be equipped with a sufficient number of flow measuring devices to permit the continuous measurement and recording of the flow rate and daily volume of water conveyed into the treatment system and the flow rate and daily volume of water conveyed from the treatment system to the distribution system. The EAPWSS is equipped with two (2) north and south raw water flow meters; four (4) filtered water flow meters; one (1) wash water flow meter; one (1) service wash water flow meter; and two (2) east and west treated water (finished water) flow meters to comply with the requirements of the PTTW and the MDWL. Documentation provided at the time of inspection, confirmed that all flow meters had been calibrated annually. Instrumentation calibrations verify that the accuracy of the raw water and treated water flow meters installed at the EAPWSS operated within an acceptable range during the inspection review period. The Owner/Operating Authority should also be aware that O. Reg. 170/03 Schedule 6 (5) defines the frequency of equipment checks which states the following: "If this Regulation or an approval, municipal drinking water licence or order, including an OWRA approval or OWRA order, requires at least one water sample to be taken every 12 months and tested for a parameter, the owner of the drinking water system and the operating authority for the system shall ensure that at least one sample that is taken during a 12-month period for the purpose of being tested for that parameter is taken not more than 30 days before or after the first anniversary of the day a sample was taken for that purpose in the previous 12-month period." and O. Reg. 170/03 Schedule 6 (8) "This section applies, with necessary modifications, if this Regulation or an approval, drinking water works permit, municipal drinking water licence or order, including an OWRA approval or OWRA order, requires equipment to be checked at intervals to which any of subsections (1) to (7) apply." The owner was in compliance with the conditions associated with maximum flow rate or the rated capacity conditions in the Municipal Drinking Water Licence issued under Part V of the SDWA. Schedule C Section 1.0 of Municipal Drinking Water Licence # Issue Number 5 specifies the EAPWSS must not be operated in a manner that exceeds the rated capacity of the treatment plant process (no greater than 91,000 m³/day). A review of the water taking records provided by the owner for the inspection, found that any exceedances of the water taking limits during the inspection review period were for a short duration and did not continue as a maximum stabilized/sustainable rate. Records of flows and any capacity exceedances were made by the OIC in accordance with the Permit and Licence or Approval issued under Part V of the SDWA. The information provided by the Owner/Operating Authority in the 2016 Compliance Report indicates that the EAPWSS was operating at a daily average (treated water flow) of approximately forty seven percent (47%) of the rated capacity and a maximum daily peak flow at sixty three percent (63%) of the plant capacity. EAPWSS was operating at a daily average (Raw water flow) of approximately forty nine percent (49%) of the rated capacity and a maximum daily peak flow at seventy four percent (74%) of the plant capacity. Treatment Processes The owner had ensured that all equipment was installed in accordance with Schedule A and Schedule C of the Drinking Water Works Permit. During the physical inspection, the equipment located at the EAPWSS was reviewed against the description in the current Drinking Water Works Permit (DWWP). The equipment at the EAPWSS was observed to be comparatively consistent with the descriptions in Schedule A and C of the DWWP. The owner/operating authority was in compliance with the requirement to prepare Form 2 documents as required by their Drinking Water Works Permit during the inspection period. Report Generated for millerji on 30/11/2017 (dd/mm/yyyy) Page 8 of 20

12 Treatment Processes During the inspection review period, numerous Form 2s were provided by the Operating Authority of the EAPWSS to document minor modifications and replacement of equipment. It was noted during the inspection documentation review, that replacements and or minor modifications to the facilities meet the requirements of DWWP , Issue Number 5, issued July 7, 2017, Schedule B section 4.0 Records indicated that the treatment equipment was operated in a manner that achieved the design capabilities required under Ontario Regulation 170/03 or a Drinking Water Works Permit and/or Municipal Drinking Water Licence issued under Part V of the SDWA at all times that water was being supplied to consumers. At the time of inspection, all equipment including online continuous analyzers; data loggers; duty and stand-by metering pumps etc. were operational and connected to the system. Records confirmed that the water treatment equipment which provides chlorination or chloramination for secondary disinfection purposes was operated so that at all times and all locations in the distribution system the chlorine residual was never less than 0.05 mg/l free or 0.25 mg/l combined. Documentation reviewed for the inspection period, indicate that the free chlorine residual for the distribution system was within acceptable limits during the course of this inspection period. The primary disinfection equipment was equipped with alarms or shut-off mechanisms that satisfied the standards described in Section 1-6 (1) of Schedule 1 of Ontario Regulation 170/03. The UV disinfection systems are equipped with an alarm and automatic shutdown capability. The UV units are programmed to shut down in the event of a system failure or if an operational parameter is exceeded (i.e. UV dose < 40 mj/cm²). The alarms are dispatched electronically and must be acknowledged / acted upon by an operator. Treatment Process Monitoring Primary disinfection chlorine monitoring was conducted at a location approved by Municipal Drinking Water Licence and/or Drinking Water Works Permit issued under Part V of the SDWA, or at/near a location where the intended CT has just been achieved. Detail regarding how primary disinfection is achieved at the treatment plant is contained in the Operation and Maintenance Manual. The operators have access to a CT calculator and chart to determine if CT has been achieved for primary disinfection. The chlorine monitoring at the treatment plant is conducted after the treated water has passed through the filters, UV disinfection units and clear well and reservoir. At this point, it is understood that primary disinfection has taken place as long as the minimum chlorine residual identified in the CT calculation has been met. A free chlorine analyzer is used for this purpose at Station 5 (final treated water). Continuous monitoring of each filter effluent line was being performed for turbidity. O.Reg.170/03, Schedule 7 section 7-3 (2) requires continuous monitoring equipment of each filter effluent line. Continuous monitoring for turbidity is required only of the filter effluent that is directed to the next treatment process/stage (and eventually to the distribution system). At the time of inspection each filter effluent line had a functioning continuous turbidity analyzer which operates at all times when water is being supplied / produced. The filter effluent from each individual filter must meet the performance criterion for filtered water turbidity of less than or equal to 0.3 NTU in 95% of the measurements each month. The Operating Authority uses SCADA data to determine if the monthly turbidity average meets this requirement. Documentation provided for the inspection period, indicates that each of the four filters met the requirement for turbidity. The Operating Authority has a contractual requirement with the Owner to meet 0.1 NTU in 95% of the measurements each month. Report Generated for millerji on 30/11/2017 (dd/mm/yyyy) Page 9 of 20

13 Treatment Process Monitoring The secondary disinfectant residual was measured as required for the distribution system. In accordance with O. Reg. 170/03 Schedule 7-2 (3) The Owner of a large municipal residential system that provides secondary disinfection, the operating authority for the system shall ensure that at least seven distribution samples are taken each week in accordance with subsection (4) and are tested immediately for, (a) free chlorine residual, if the system provides chlorination and does not provide chloramination; (4) The following rules apply to the distribution samples referred to in subsection (3) unless at least one sample is taken on each day of the week: 1. At least four of the samples must be taken on one day of the week, at least 48 hours after the last sample was taken in the previous week. 2. At least three of the samples must be taken on a second day of the week, at least 48 hours after the last sample was taken on the day referred to in paragraph When more than one sample is taken on the same day of the week under paragraph 1 or 2, each sample must be taken from a different location. All distribution free available chlorine (FAC) residual measurements provided by the Owner for the inspection review period were appropriately documented including the time, date, FAC residual and the person who analyzed the sample. In addition to the above, the Owner has installed continuous secondary disinfection monitoring analyzers in accordance with O. Reg. 170/03 Schedule 6 to provide free chlorine residual sampling, testing, alarming and recording of data. Operators were examining continuous monitoring test results and they were examining the results within 72 hours of the test. Documentation provided at the time of inspection, indicate that the data was reviewed within the prescribed 72 hour period. Typically the operator reviews the data on a daily basis and records the minimum, maximum and mean values on the daily log sheet. All continuous monitoring equipment utilized for sampling and testing required by O. Reg.170/03, or Municipal Drinking Water Licence or Drinking Water Works Permit or order, were equipped with alarms or shut-off mechanisms that satisfy the standards described in Schedule 6. EAPWSS has several components (chlorine, turbidity and fluoride analyzers, and UV disinfection units) that are linked to the SCADA system. These components have the ability to trigger an alarm to alert operators and shutdown the water system to prevent improperly disinfected water or any water quality issues outside the predetermined set points. Continuous monitoring equipment that was being utilized to fulfill O. Reg. 170/03 requirements was performing tests for the parameters with at least the minimum frequency specified in the Table in Schedule 6 of O. Reg. 170/03 and recording data with the prescribed format. The Owner/Operating Authority must ensure that continuous monitoring and recordings conducted at all times as prescribed by O. Reg. 170/03 Schedule 6-5 (1) which states: " If a drinking water system uses continuous monitoring equipment for sampling and testing that is required under this Regulation, or under an approval or order, for a parameter set out in the Table to this section, the owner of the system and the operating authority for the system shall ensure that the following standards are met: 1. The continuous monitoring equipment must, except when no water is being directed to users of water sampled by the equipment, i. test for the parameter with at least the minimum frequency specified in the Table for the parameter, and ii. record the date, time, sampling location and result of every test for the parameter with at least the minimum frequency referred to in subparagraph i. 2. If the continuous monitoring equipment tests for a parameter more often than is required by subparagraph 1 i, the Report Generated for millerji on 30/11/2017 (dd/mm/yyyy) Page 10 of 20

14 Treatment Process Monitoring equipment may, instead of complying with subparagraph 1 ii, i. record the minimum, maximum and mean results of tests for the parameter for every period that is equal to the length of time referred to in subparagraph 1 i, along with the sampling location, the date of the tests conducted during the period and the time at the end of the period, and ii. record the result of every test that causes an alarm to sound under paragraph 1 of subsection 1.1), along with the sampling location and the date and time of the test." All continuous analysers were not calibrated, maintained, and operated, in accordance with the manufacturer's instructions or the regulation. During normal plant operations at the EAPWSS, records indicate that, the OIC/ORO and operator failed to ensure that all filter effluent values (regulated analyzers recording outside required margins of error) in the process were properly monitored, inspected tested and calibrated. More specifically, Filter #3 Effluent monitoring during the months and days of June 14, thru to the 28, 2016, and October 10 thru to the 22, Filter #4 Effluent monitoring during the months and days of June 28, thru to July 1, 2, 3, 4 and 5, Records provided indicate that on occasion the OIC noted having issues with the operation of the filtration analyzers at the EAPWSS (lamp failure, fault errors and instrumentation drift). Log records did not however identify any issues found during the trending review by the Operator. On one occasion, the OIC conducted some operational steps to meet compliance (i.e. collect and record grab samples or removed the filter from service) the ORO/OIC/Operator did continue the operation of the filters which fail to meet the mandatory requirements for continuous monitoring of turbidity (NTU) for each filter. The above findings are also in violation of O. Reg. 170/03, Schedule 1, General Obligations, s,1-2 (2) 2, requiring that the water treatment equipment is operated in accordance with the "Ministry's Procedure for Disinfection of Drinking Water in Ontario" which states that "Every water turbidity analyzer installed for the purpose of monitoring the effectiveness of the filtration process (usually ahead of the primary disinfection process) must be calibrated at a frequency necessary to ensure the appropriate operation of the analyzer." Operations Manuals The operations and maintenance manuals contained plans, drawings and process descriptions sufficient for the safe and efficient operation of the system. The Owner/Operating Authority provided documentation confirming that the operators and maintenance personnel in the subsystem have been provided ready access to comprehensive operation and maintenance manuals that contain plans, drawings and process descriptions sufficient for the safe and efficient operation of the subsystem as required by O. Reg. 128/04, s. 28. The operations and maintenance manuals met the requirements of the Drinking Water Works Permit and Municipal Drinking Water Licence issued under Part V of the SDWA. During the site inspection, the operations and maintenance manuals provided for review treatment facility included a list of the criteria as set out by the EAPWS Municipal Drinking Water Licence , Schedule B 16.0 Operations and Maintenance Manuals. The Owner/Operating Authority should conduct a detailed review and evaluation (ensure information contained within the operations manuals is relevant to current operations and system drawings) of the Operations and Maintenance Manuals currently in place, to meet with the prescribed regulatory framework. In addition to the above, the Owner/Operating Authority is reminded that operational procedures are in place prior to the operation of the system as per MDWL # section 16.3 which states: "Procedures necessary for the operation and maintenance of any alterations to the drinking water system shall be incorporated into the operations and maintenance manual or manuals prior to those alterations coming into operation." Logbooks Report Generated for millerji on 30/11/2017 (dd/mm/yyyy) Page 11 of 20

15 Logbooks Records or other record keeping mechanisms confirmed that operational testing not performed by continuous monitoring equipment was being done by a certified operator, water quality analyst, or person who suffices the requirements of O. Reg. 170/ All log records regarding O. Reg. 170/ reviewed during the inspection period, identified the names of all operators of the facility and their respective signatures and/or initials. It should be noted that any entries in the log must be identified by the person making the entry in the logs. An example of this is if multiple operators make entries in the log. If this occurs, those persons must clearly identify who made the entry (i.e. by signature or initial). Security The owner had provided security measures to protect components of the drinking water system. At the time of inspection, the EAPWSS facilities were securely locked. Entrance doors at all the buildings have intrusion alarms which are monitored via the SCADA system at the main treatment facility. Security measures also include lockable access gates and "No Trespassing" signs. Operators typically visit the remote facilities on a regular basis in order to ensure that the system integrity has not been compromised. The main treatment facility has operational staff working 24 hours per day and is monitored by a camera surveillance system. Certification and Training The overall responsible operator had been designated for each subsystem. The Elgin Area Primary Water Supply System is classed as a Water Treatment Subsystem Class 4 and a Water Distribution Subsystem Class 3. At the time of inspection, the designated (and backup) ORO possessed an operator certificate that was equal or greater than the classification level of the treatment plant and distribution system. Operators in charge had been designated for all subsystems which comprised the drinking-water system. During the inspection period, it was found that the Operators responsible for the operations of the EAPWSS recorded the names of the operator-in-charge (OIC) in the facility log records. The Owner/Operating Authority must ensure that one or more operators are designated as operator-in-charge (OIC) for each day that the facility is in operation. An OIC can be any operator with an applicable certificate to the type of operated subsystem. An operator-in-training (OIT) cannot be designated as an OIC; any log entries made by the OIT must be approved by the OIC and clearly documented in the log at the time of entry. In accordance with O. Reg. 128/04 s. 25 (1) The owner or operating authority of a subsystem or a person authorized by the owner or operating authority shall designate one or more operators as operators-in-charge of the subsystem. O. Reg. 128/04, s. 25 (1). All operators possessed the required certification. A review of the operational staff certificates at the EAPWSS indicates that during the inspection period, all operators of the drinking water system/subsystems had adequate certification. Only certified operators made adjustments to the treatment equipment. Documentation provided at the time of inspection, (logbooks and other record keeping mechanisms) indicated that only certified operational staff made adjustments to treatment/distribution system processes. The Owner/Operating Authority must be aware that the Safe Drinking Water Act (SDWA) Section 11. (1) 5 require the owner and/or the operating authority to ensure that the personnel at the drinking-water system are under the supervision of persons having the prescribed qualifications. The Owner/Operating Authority can reference the web site at the following link: "Certification Guide for Report Generated for millerji on 30/11/2017 (dd/mm/yyyy) Page 12 of 20

16 Certification and Training Operators and Water Quality Analysts of Drinking Water Systems", section 5 "Certification of Operators" which identifies functions that must be performed by a certified operator. The Certification Guide identifies that certain duties must be performed by a certified operator, or at least have a certified operator (or P. Eng. designated as OIC) physically present and monitoring the work being performed. It also identifies duties that can be undertaken by uncertified personnel without the direct physical supervision of the person with prescribed qualifications. However, this does not relieve the OIC from ensuring responsibilities under O. Reg. 128/04 s. 26 (2) are met for any work in the drinking-water system. It is recommended that the guide be provided to the system operational staff for informational purposes to heighten operator's awareness, and to help them fully understand their legal responsibilities and certification compliance requirements. Water Quality Monitoring All microbiological water quality monitoring requirements for distribution samples were being met. A review of the statement of analytical results for the inspection period confirmed that a minimum of three (3) distribution samples were taken each week and analyzed for E.coli, total coliform and HPC. In accordance with O. Reg. 170/03, Schedule 10-2, and based on the population served of less than a 1000 persons, the Owner/Operating Authority is required to take a minimum of eight (8) distribution system samples each month, ensuring that at least one sample is taken in each week of the month. Each of the distribution samples are to be analyzed for E.coli, total coliform and 25% of the samples must be analyzed for background colony counts based on a heterotrophic plate count (HPC).

In accordance with O. Reg. 170/03, Schedule 13-7, the Owner/Operating Authority for the EAPWSS shall continue to ensure that a sample is collected from the treated water supply and tested every three (3) months for nitrate and nitrite. Documentation provided by the Owner/Operating Authority during the inspection period indicates that all quarterly nitrate/nitrite water quality monitoring requirements have been met. Monitoring was completed on the following dates during the inspection period: January 10, 2017, April 11, 2017, July 4, 2017, October 11, 2016 and July 5, All sodium water quality monitoring requirements prescribed by legislation were conducted within the required frequency. In accordance with O. Reg. 170/03, Schedule 13-8, the Owner/Operating Authority is required to sample and test for sodium on the treated water every sixty (60) months. A treated water sodium sample was collected on January 10, The required daily samples were being taken at the end of the fluoridation process. In accordance with O. Reg. 170/03, Schedule 6-4, the Owner/Operating Authority of the EAPWSS shall continue to ensure that continuous on-line fluoride analyzer monitoring of the fluoride residual is reviewed every 72 hours as a minimum by the operation staff as per Schedule 6-5 (1) 3. At the time of inspection, the fluoride monitoring was being conducted by the SCADA system and had an active alarm system. In addition to the above, the Owner/Operating Authority must also comply with O. Reg. 170/03, Schedule 7-4 to ensure that at least one grab sample is collected each day and tested for fluoride. During review of the EAPWSS daily lab analysis form, it was found that the operator collected two (2) grab samples daily at the EAPWSS and analyzed the fluoride concentration. Documentation provided by the Owner/Operating Authority during the inspection period, indicates that fluoride water quality monitoring and reporting requirements have been met as prescribed in the MDWL Issue 5 section 2.0 "Other Regulatory Relief" granting the following conditions: Report Generated for millerji on 30/11/2017 (dd/mm/yyyy) Page 14 of 20

18 Water Quality Monitoring "A result indicating that the concentration of fluoride exceeds 1.5 milligrams per litre where the duration of the exceedance is greater than 5 minutes measured continuously or 15 minutes calculated as the sum of exceedances over the previous 24 hours is an adverse result for the purpose of section 18 of the SDWA if a report under subsection 18(1) of the SDWA has not been made in respect to fluoride in the preceding 24 hours." All water quality monitoring requirements imposed by the Municipal Drinking Water Licence and Drinking Water Works Permit were being met. Records confirmed that chlorine residual tests were being conducted at the same time and at the same location that microbiological samples were obtained. During the documentation review, records reviewed verify that chlorine residuals are being collected at the same time and location as microbiological samples from the treatment plant and the water distribution system. The Owner/Operator has fulfilled the requirements prescribed by O. Reg. 170/03 6-3(1) which requires a water sample be taken and tested for a microbiological parameter, the owner of the drinking water system and the operating authority for the system shall ensure that another sample is taken at the same time from the same location and is tested immediately for, (a) free chlorine residual, if the system provides chlorination and does not provide chloramination; or (b) combined chlorine residual, if the system provides chloramination. Water Quality Assessment Records showed that all water sample results taken during the inspection review period did not exceed the values of tables 1, 2 and 3 of the Ontario Drinking Water Quality Standards (O.Reg. 169/03). Reporting & Corrective Actions Where required continuous monitoring equipment used for the monitoring of chlorine residual and/or turbidity triggered an alarm or an automatic shut-off, a qualified person responded in a timely manner and took appropriate actions. Chlorine and turbidity analytical results are continuously monitored by the SCADA system in the water treatment plant and in the water distribution system. When these processes reach a set point or value, the SCADA system generates an alarm to notify the shift operator on duty. Details of alarm responses are written in the facility logbook by operators. The operator typically makes a note related to the actions taken for the specific set point exceedance. After reviewing the monitoring data provided by the Owner/Operating Authority, it was found that operators responded to the alarms generated during the inspection period within a reasonable amount of time. When the primary disinfection equipment, other than that used for chlorination or chloramination, has failed causing an alarm to sound or an automatic shut-off to occur, a certified operator responded in a timely manner and took appropriate actions. The UV disinfection is monitored via the SCADA system and when a set point or value triggers an event, the SCADA system generates an alarm to notify the shift operator on duty. Other Inspection Findings The following instance(s) of non-compliance were also noted during the inspection: 1/ The operator-in-charge did not ensure that records were maintained of all adjustments made to the processes within his or her responsibility. Report Generated for millerji on 30/11/2017 (dd/mm/yyyy) Page 15 of 20

19 Other Inspection Findings During the inspection period, it was found that the Operating Authority failed to ensure that all actions taken by the operator or OIC during the shift were appropriately recorded specifically during the calibration of regulated continuous online water quality analyzers. Some examples of adjustments that must be recorded include: changes to chemical dosages, monitoring equipment calibration, changes to alarm set points, pump switchovers or alterations to flow and equipment taken out of service for maintenance. 2/ Logs for the treatment subsystem(s) of the drinking water system did not contain the required information. During review of the EAPWSS log book, it was found that the OIC on multiple occasions failed to maintain log records per O. Reg. 128/04, s. 27 (5) namely during the calibrations of regulated continuous online analyzers and names of all operators on shift. The logbooks/records maintained at the EAPWSS, lack several requirements specified in O. Reg. 128/04 s. 27 (5) 2, 3, 4, 5, and 6. Many entries state an unusual or abnormal situation but there is no explanation provided by the author of the entry regarding to the actions taken and any conclusions drawn from the observation.

27 Drinking Water System Appendix B Inspection Rating Record and Inspection Risk Methodology

28 April 2012 APPLICATION OF THE RISK METHODOLOGY USED FOR MEASURING MUNICIPAL RESIDENTIAL DRINKING WATER SYSTEM INSPECTION RESULTS The Ministry of the Environment (MOE) has a rigorous and comprehensive inspection program for municipal residential drinking water systems (MRDWS). Its objective is to determine the compliance of MRDWS with requirements under the Safe Drinking Water Act and associated regulations. It is the responsibility of the municipal residential drinking water system owner to ensure their drinking water systems are in compliance with all applicable legal requirements. This document describes the risk rating methodology, which has been applied to the findings of the Ministry s MRDWS inspection results since fiscal ontario.ca/drinkingwater PIBS 6797e year The primary goals of this assessment are to encourage ongoing improvement of these systems and to establish a way to measure this progress. MOE reviews the risk rating methodology every three years. The Ministry s Municipal Residential Drinking Water Inspection Protocol contains up to 14 inspection modules and consists of approximately 120 regulatory questions. Those protocol questions are also linked to definitive guidance that ministry inspectors use when conducting MRDWS inspections.
