7 Ministry of the Environment and Climate Change Inspection Report 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 70/03, "Drinking Water Systems" (O.Reg. 70/03). This inspection has been conducted pursuant to Section 8 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. 72/03 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. Water Inspector's Jim Miller and Tyler Kelly conducted an unannounced physical inspection of the St. Paul's Drinking Water System, Water Works # on June 6, 207. This inspection covers the period from April 30, 206 to May 3, 207. Documents reviewed in association with this report include but are not limited to: ) Ministry of the Environment and Climate Change Drinking Water Works Permit # Issue Number: 3, dated April 2, 206; 2) Ministry of the Environment and Climate Change Municipal Drinking Water Licence # Issue Number: 2, dated April 2, 206; 3) Ministry of the Environment and Climate Change Permit To Take Water # WJ9U dated May 2, 200. This report also includes a review and assessment of compliance and operating practices in relation to the following Acts and Regulations: ) Safe Drinking Water Act, 2002; 2) Drinking Water Systems Regulation, (Ontario Regulation 70/03); 3) Ontario Drinking-Water Quality Standards (Ontario Regulation 69/03); 4) Ontario Water Resources Act, 990 and associated regulations; 5) Certification of Drinking-Water System Operators and Water Quality Analysts (Ontario Regulation 28/04). Other operational documents maintained by the owner/operating authority for the period April 30, 206 through May 3, 207 were also reviewed in conjunction with this inspection.

8 Ministry of the Environment and Climate Change Inspection Report Source surface water and other foreign materials. At the time of the physical inspection, the well was in good condition equipped with a commercially manufactured watertight, vermin-proof well cap, complete with a screened air vent. The casing height was greater than 40 cm above the ground surface and signs of surface water pooling were not noted. Also, a review of the raw water quality does not indicate influence from surface water or other foreign material. In addition, the owner/operating authority has prepared a Well Inspection and Maintenance Plan to ensure the well is maintained in a secured state. Measures were in place to protect the groundwater and/or GUDI source in accordance with any the Municipal Drinking Water Licence and Drinking Water Works Permit issued under Part V of the SDWA. The Operations and Maintenance Manual includes a Well Inspection and Maintenance Plan as required by Schedule B, Section 6, of the Municipal Drinking Water License # issue # 2 issued on April 2, 206. The plan defines the schedule for inspections and maintenance procedures on the production Well. A remedial action plan is also defined for situations where an inspection indicates non-compliance with respect to regulatory requirements. 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. Schedule C, Section 2.0 of the Municipal Drinking Water Licence issue # 2 issued on April 2, 206 for the St. Pauls Drinking Water System states that the following flow rates must be measured and recorded: ) The flow rate and daily volume of treated water that flows from the treatment system to the distribution system and; 2) The flow rate and daily volume of water that flows into the treatment system. St. Pauls Drinking Water System has one () treated flow meter. The flow meter records the amount of treated flow prior to entering the distribution systems. The flow meter records the average, maximum, and minimum flow rate in every five minute period to the data logger. 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.0 (.) of the Municipal Drinking Water Licence Issue # 2 issued on April 2, 206 for the St. Pauls Drinking Water System states that the maximum daily volume of treated water entering the distribution system shall not exceed m3/day.

9 Ministry of the Environment and Climate Change Inspection Report Treatment Processes ) The one () standby Sodium Hypochlorite chemical feed pump required by Drinking Water Works Permit was not connected to a power source, therefore making it offline. The Drinking Water Works Permit requires one () duty and one () standby Sodium Hypochlorite chemical feed pumps. Standby equipment is considered to be equipment that can be made duty by the manual act of switching over (flipping an on/off switch) or an automatic switch over of equipment initiated by a signal from a monitoring system. 2) During the inspection there was only one () duty Sodium Silicate chemical feed pump at the drinking water system. The Drinking Water Works Permit requires one () duty and one () offline Sodium Silicate chemical feed pumps. Records indicated that the treatment equipment was operated in a manner that achieved the design capabilities required under Ontario Regulation 70/03 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. The St. Pauls Drinking Water System utilizes UV for primary disinfection, and sodium hypochlorite for secondary disinfection of the groundwater supply. A review of the data provided by the operating authority indicates that the UV disinfection units and sodium hypochlorite injection system is operated in a manner that achieves disinfection requirements. 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 mg/l free or 0.25 mg/l combined. Documentation provided by the operating authority indicates that during the inspection period the free chlorine residuals were greater than 0 mg/l in the distribution system. The primary disinfection equipment was equipped with alarms or shut-off mechanisms that satisfied the standards described in Section -6 () of Schedule of Ontario Regulation 70/03. The St. Pauls Drinking Water System uses three (3) Hallett 30 UV Pure to achieve primary disinfection. Each Hallett 30 UV Pure is equipped with an automatic shut-off valve that will cease the flow of water to the distribution system if the UV units malfunction, loses power or is not providing a disinfection dose of 40 mj/cm2. The UV units are also equipped with an auto-dialer alarm system that contacts the operator on call to notify them of the issue. Treatment Process Monitoring The secondary disinfectant residual was measured as required for the distribution system. In accordance with Ontario Regulation 70/03 Schedule 7-2 (5), the owner/operating authority shall ensure that at least 2 distribution samples are collected and immediately tested for free chlorine residual. Ontario Regulation 70/03 Schedule 7-2 (6), states that at least one of the distribution samples shall be taken 48 hours after and during the same week as, one of the other distribution samples. Records provided from the operating authority indicate that the St. Pauls Drinking Water System collected and tested for free chlorine residual within the frequency stated in Ontario Regulation 70/03 Schedule 7-2 (6). Operators were examining continuous monitoring test results and they were examining the results within 72 hours of the test. The operators examine the continuous monitoring data on a daily basis. All continuous monitoring data during the inspection period was reviewed within 72 hours. All continuous monitoring equipment utilized for sampling and testing required by O.

18 Ministry of the Environment and Climate Change Inspection Report SUMMARY OF RECOMMENDATIONS AND BEST PRACTICE ISSUES This section provides a summary of all recommendations and best practice issues identified during the inspection period. Details pertaining to these items can be found in the body of the inspection report. In the interest of continuous improvement in the interim, it is recommended that owners and operators develop an awareness of the following issues and consider measures to address them.. The following issues were also noted during the inspection: During the physical inspection, the exterior portion of the bypass discharge pipe did not have a screen installed. Installing a screen on the bypass discharge pipe is a recommended best management practice to prevent the entry of foreign material into the treatment system. Recommendation: As of June 7, 207, the operating authority installed a screen to the bypass discharge pipe. Photographs of the screened bypass discharge pipe were forwarded to Jim Miller of the Ministry of the Environment and Climate Change, London District Office. It is recommended that the operating authority periodically checks the integrity of the screen and replaces the screen if the integrity has been compromised.

38 Ministry of the Environment Drinking Water System Inspection Report Appendix C Inspection Rating Record and Inspection Risk Methodology

39 April 202 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 4 inspection modules and consists of approximately 20 regulatory questions. Those protocol questions are also linked to definitive guidance that ministry inspectors use when conducting MRDWS inspections.
