VIA eMAIL Re: Retirement Announcement – Rob Andrews, President and CEO

Ontario Clean Water Agency

Chairs and Members; On January 9th, Rob Andrews, President and CEO of the Ontario Clean Water Agency, announced his pending retirement effective February 3, 2017. Rob Andrews has been President and CEO of OCWA for three years and has overseen a significant transformation of the Crown Corporation during his tenure. Beyond the dedication and commitment of the OCWA staff in the Huron/Elgin OCWA Hub, this transformation has contributed to the operational success and improvements in the Lake Huron and Elgin Area water system that we see today. Board staff have had discussions with Rob and some of his senior leadership team, and are confident that this transformation and operational success will continue with Rob’s successor. I wanted to take this opportunity to advise each of you of this pending retirement, and assure the Boards of Management that your staff will continue to work diligently with OCWA and its new CEO to ensure the continued success of the regional water systems. As always, if you have any questions or concerns, please do not hesitate to contact me at your earliest convenience. Best regards,

To: Chair and Members Lake Huron Primary Water Supply System Board of Management

From: Kelly Scherr, P.Eng., MBA, FEC Chief Administrative Officer

Meeting Date: March 9, 2017

Subject: Quarterly Compliance Report (4th Quarter 2016: October - December)

RECOMMENDATION

That the Quarterly Compliance report with respect to the general, regulatory and contractual obligations of the Lake Huron Primary Water Supply System BE RECEIVED for the information of the Board of Management; it being noted that there were no Adverse Water Quality Incidents or adverse laboratory results in the 4th quarter of 2016.

BACKGROUND

Pursuant to Board of Management resolution, this Compliance Report is prepared on a quarterly basis to report on general, regulatory and contractual compliance issues relating to the regional water system. For clarity, the content of this report is presented in two basic areas, namely regulatory and contractual, and does not intend to portray an order of importance or sensitivity nor a complete list of all applicable regulatory and contractual obligations.

REGULATORY ISSUES

Recent Regulatory or Other Changes:

Regulation Decision: Updates to Ontario’s Drinking Water Quality Standards and other regulations of the Safe Drinking Water Act, 2002, related to: lead in schools and day nurseries; drinking water systems; drinking water testing services; and drinking water operator certification

The Ministry of the Environment and Climate Change (MOECC) has finalized revisions to several regulations under the Safe Drinking Water Act. With the exception of one amendment related to laboratory reporting of pesticides, the amended regulations will be in force on July 1, 2017. The exception related to pesticides sets a specific minimum reporting limit of 100 nanograms for all pesticides, regardless of whether there is a Maximum Allowable Limit is established, and requires laboratories to submit to the MOECC results from all drinking water tests for which they are licensed to analyze, and comes into effect on January 1, 2018.


File No. H17/2017

Report Page 2 of 25 March 9, 2017 Quarterly Compliance Report

Changes to O.Reg. 169/03 (Ontario’s Drinking Water Quality Standards): Three new drinking water quality standards based on new federal guidelines will be introduced:

0.06 mg/L for Toluene; 0.14 mg/L for Ethylbenzene; and 0.09 mg/L for Total Xylenes

Two drinking water quality standards will be revised: From 0.01 mg/L to 0.05 mg/L for Selenium; and From 0.03 mg/L to 0.01 mg/L for Tetrachloroethylene.

One drinking water standard, which is a sum of nitrate and nitrite, will be removed. This standard is redundant since there are individual standards for these parameters. Consequently, the following drinking water quality standard will be removed:

10 mg/L for Nitrate + Nitrite. Changes to the MOECC’s Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines: One new Aesthetic Objective will be introduced:

0.015 mg/L for methyl t-butyl ether (MTBE). Two Aesthetic Objectives will be revised:

From 0.0024 mg/L to 0.0016 mg/L for ethylbenzene; and From 0.3 mg/L to 0.02 mg/L for xylenes.

Changes to O.Reg. 170/03 (Drinking Water Systems): All pesticides found at levels above 100 nanograms/Litre (ng/L) will initiate an AWQI. This includes pesticides that are not included in Schedule 2 of O. Reg. 169/03 and currently do not have a drinking water standard in place.

All test results that indicate the presence of pesticides – even if their concentration levels are at or below the threshold of 100 ng/L – will need to be provided to the ministry.

Municipal and non-municipal drinking water system owners will no longer be required to submit lead testing summary reports to the ministry, as the same information will have to be included in the system’s annual report which is required to be made available to the public. In addition, general changes and corrections were made to the regulation. Changes to O.Reg. 128/04 (Certification of Drinking Water Operators and Water Quality Analysts): Requirements for Drinking Water Operator-in-Training (OIT) Certification have been updated as follows:

Temporary Drinking Water OIT certificates will cease to be issued. Drinking water OIT certificates will be valid for 36 months. Drinking water OITs will be permitted to operate Limited Systems under the supervision of an

Operator-in-Charge or Overall Responsible Operator. The changes to O.Reg. 243/07 (Schools, Private Schools and Day Nurseries) and O.Reg. 248/03 (Drinking Water Testing Services) do not impact the Lake Huron Primary Water Supply System (LHPWSS).


File No. H17/2017


Potential Impacts to the Board: The impacts of the regulatory changes will be minimal for the LHPWSS. Historical water quality data for the LHPWSS is available for selenium, toluene, ethylbenzene, total xylenes and tetrachloroethylene. All results to date are non-detect. There is no data available for methyl t-butyl ether (MTBE) in either the LHPWSS water quality database or the MOECCC’s research data. The MOECC is proposing an aesthetic objective only, and therefore there is no immediate concern. The changes to operator certification is applicable mainly to the operating authority who employs the certified operators. New Environmental Bill of Rights (EBR) Registry Postings: At the time of drafting this report, there were proposed regulations or policies posted on the Environmental Bill of Rights (EBR) Registry for public comment, or in the draft consultation process with the Ministry of the Environment and Climate Change (MOECC) or other agencies as follows:

Proposed Guideline Technical Document on Lead in Drinking Water Health Canada has issued a proposed guideline technical document on lead in drinking water for public comment. The proposed Maximum Acceptable Concentration (MAC) for lead in drinking water is being lowered from 0.01 mg/L (10 µg/L) to 0.005 mg/L (5 µg/L). Health Canada’s existing guideline for lead was last updated in 1992. The current MAC of 0.01 mg/L was based on health risk and established from recommendations by the World Health Organization (WHO). The proposed new MAC of 0.005 mg/L is based on considerations that the MAC must be measurable, achievable at reasonable cost, and have a significant impact on the blood lead levels of children which are the most vulnerable population. The new guideline document identifies reductions in IQ as the critical effect of lead, with the proposed MAC of 0.005 mg/L based on analytical achievability. The revised guideline document provides updated data and information related to exposure to lead in Canada, to analytical methods and to treatment approaches available at the municipal and residential scales. Based on this information, the document proposes a lowered MAC of 0.005 mg/L for total lead in drinking water. Potential Impacts to the Board: The province of Ontario has established a MAC of 0.01 mg/L for lead in drinking water. If Health Canada adopts a lowered MAC, it is likely that Ontario will also eventually follow suit and consider adopting a lowered MAC. Any future regulatory changes proposed by the MOECC for Ontario would be subject to a regulation proposal notice posted on the EBR registry for public comment. Lead is usually found in drinking water as a result of leaching from distribution and plumbing system components. The LHPWSS is a treatment and transmission system only, meaning that there is no distribution system directly connected to the plumbing that supplies consumers with drinking water. Ontario municipalities are required to conduct lead sampling within their distribution systems. Where the prescribed standard for lead is exceeded, municipalities may be required to develop a Corrosion Control Plan (CCP). If a municipality that obtains water from the LHPWSS was required to implement a CCP, the LHPWSS would also be required to jointly participate in the development of the CCP.


File No. H17/2017


There are currently 29 water systems in Ontario that have a CPP as a result of lead levels in the drinking water. It has been estimated by the MOECC that if the lead standard were reduced from 0.01 mg/L to 0.005 mg/L, consistent with the Health Canada guideline, it is anticipated that the number of water systems requiring a CPP would increase to in excess of 65 systems. If the lead standard were to be reduced to 0.001 mg/L, a theoretical standard discussed during the initial consultation process with Health Canada, the number of municipal water systems in Ontario requiring a CPP would likely be in excess of 260 systems. Any future regulatory changes in Ontario could impact the LHPWSS member municipalities and subsequently the LHPWSS. The LHPWSS and City of London currently have a joint CCP in place. Quarterly Water Quality Reports: The Water Quality Quarterly Report for the period of October 1st to December 31st, 2016 inclusive was completed by the operating authority. There were no adverse laboratory test results for the LHPWSS during this quarter. The report is posted on the Water Systems’ website at www.watersupply.london.ca and is included in this report as Appendix A for the Board’s information. The water quality sample results will continue to be provided and posted on a quarterly basis for the Board’s and the public’s information. It is important to note that the Maximum Allowable Concentration (MAC) are the permitted maximum values of the listed parameter, and are considered adverse incidents where the water quality exceeds the listed value. Alternatively, “aesthetic objectives” and operational guidelines are not regulated but are included as suggested guidelines for the associated parameters. Variance of water quality beyond the listed aesthetic objective is not considered an adverse incident as there are no health risks associated with exceeding the suggested objective.

Adverse Water Quality Incidents (AWQIs): There were no AWQI reported by the operating authority during this quarter.

O.Reg. 170/03, Section 11 “Annual Reports”: Under the Drinking Water Systems Regulation (O.Reg. 170/03), an Annual Report for the LHPWSS is required to be prepared by February 28th of each year. The report summarizes water quality and maintenance information for the 2016 calendar year. This report is completed by Ontario Clean Water Agency (OCWA), the contracted operating authority for the LHPWSS. Although the report is no longer required to be submitted to the MOECC, the LHPWSS is required to provide copies of the report to drinking water systems that obtain water from this system. The Annual Report was forwarded to the LHPWSS member municipalities on February 21, 2017. A copy of the Annual Report is included in Appendix B for the information of the Board. All Annual Reports are posted on the Water Systems’ website at www.watersupply.london.ca for public information. The Annual Reports are also available for viewing at the Lake Huron Water Treatment Plant and at the Board’s Administration Office in London. Copies of all reports are available to the public upon request and free of charge as required by O.Reg. 170/03.


File No. H17/2017


O.Reg. 170/03, Section 22 “Summary Reports for Municipalities”: Under the Drinking Water Systems Regulation (O.Reg. 170/03) a summary report is required by March 31st of each year which:

Lists the requirements of the Act, the regulations, the system’s approval and any order that the system failed to meet at any time during the period covered by the report, and the duration of the failure. For each failure referred to, a description of the measures that were taken to correct the failure is required.

In order to allow the system’s owner to “assess the capability of the system to meet existing and planned uses of the system”, provide a summary of the quantities and flow rates of the water supplied, including monthly average and maximum daily flows and daily instantaneous peak flow rates, with a comparison to the systems rated capacity.

This report will also be compiled by OCWA. The Summary Report will be forwarded to the member municipalities of the LHPWSS as required by the March 31, 2017 deadline. The report will be posted on the Water Systems’ website at www.watersupply.london.ca for public information. All Summary Reports are available for viewing at the Lake Huron Water Treatment Plant and at the Board’s Administration Office in London. Copies of all reports are available to the public upon request and free of charge as required by O.Reg. 170/03.

CONTRACTUAL ISSUES

ARTICLE 3, “Operation and Maintenance of the Facilities – General”: Board staff informally meets with OCWA on a monthly basis to discuss operations and maintenance related issues, and on a formal basis quarterly to review contractual performance. The 2016 fourth quarter Contract Report was received from OCWA on January 30, 2017 and is scheduled to be discussed at the next quarterly administration meeting between Board staff and OCWA. Copies of the monthly Operations and Maintenance Reports, or quarterly reports are available at the Board’s Administration Office in London upon request.

Information for this report was provided by Erin McLeod, Quality Assurance & Compliance Manager.

Describe your Drinking-Water System

The Lake Huron Water Treatment Plant (WTP) employs pre-chlorination, screening, powder

activated carbon addition (seasonally on an as-required basis), coagulation, flocculation,

sedimentation, dual-media filtration, post-chlorination, and pH adjustment using sodium

hydroxide to treat raw water obtained from Lake Huron. The WTP intake crib and raw water

intake pipe have an estimated gross capacity of 454.6 Megalitres/day (MLD). The WTP rated

capacity is 340.0 MLD.

A Residue Management Facility providing equalization, clarification, sludge thickening and

dechlorination is also housed in the main complex where thickened sludge is dewatered by

centrifuges and sludge cake is sent to the landfill for final disposal. Clarified and dechlorinated

liquid streams are sent back to Lake Huron through the plant drain via the Diversion Chamber.

The distribution system is comprised of the McGillivray Booster Pumping Station and Reservoir,

the Exeter-Hensall Booster Pumping Station and Reservoir, the Arva Terminal Reservoir, the

Komoka-Mt. Brydges Booster Pumping Station (PS#4) and the associated interconnecting

transmission water mains, which includes the primary, Strathroy, Exeter-Hensall, and Komoka-

Mt. Brydges transmission water mains.

The drinking water system is monitored at various locations throughout the system via a

Supervisory Control and Data Acquisition (SCADA) system.

Subject: Environmental Management System and Quality Management System

RECOMMENDATION

That the following report with respect to the Environmental Management System and Quality Management System for the Lake Huron Primary Water Supply System BE RECEIVED for information.

DISCUSSION

Environmental Management System (EMS) The Lake Huron Primary Water Supply System (LHPWSS) has an Environmental Management System (EMS) which has been registered to the ISO14001 standard since 2003. The LHPWSS underwent a three-year re-registration audit in October 2015 and was recommended for continued registration to the ISO14001:2004 standard for another three-year period (ending in 2018). The latest revision of the standard, ISO14001:2015, was released in September 2015 and the transition to meet the requirements of the new standard will take place over the next year in advance of the anticipated re-registration in 2018. The continued utilization and registration of the EMS to the ISO14001 standard is a requirement of the Service Agreement with Ontario Clean Water Agency (OCWA), the contracted Operating Authority for the water supply system. Drinking Water Quality Management System (DWQMS) In 2006, a Drinking Water Quality Management System (DWQMS) was integrated with the existing EMS and the combined system is maintained by the contracted Operating Authority. The Safe Drinking Water Act and Municipal Drinking Water License (MDWL) require that an accredited operating authority be in operational charge of the drinking water system. In order to become accredited, the Operating Authority must maintain an operational plan that meets the requirements of the DWQMS standard, and must undergo an external accreditation audit every three years. OCWA received full scope DWQMS re-accreditation in October 2016 and is currently accredited for another three-year period (ending in 2019). Management Review The documented EMS/DWQMS and its performance requires Management Review by Top Management a minimum of once annually to ensure that the management team of the Board and the Operating Authority stay informed of environmental and quality issues. Items discussed at the Management Review meetings include, but are not limited to, water quality test results, environmental and quality performance,


File No. H17/2017


legislative changes, identified non-conformances, corrective and preventive actions, staff suggestions, changing circumstances and business strategies, and resource requirements. Corrective and preventive actions include not only those to address non-conformance issues and opportunities for improvement identified as part of internal and external audits, but also non-compliance issues identified by the Ministry of the Environment and Climate Change (MOECC), suggestions from staff, and opportunities for improvement identified during the Management Review process. In order to carry out more effective Management Review meetings, the Board’s administration has opted to conduct shorter meetings at more frequent intervals. Although each required Management Review input may not be covered at every meeting, over the course of the year all required inputs are reviewed at least once. A Management Review meeting was held on January 31, 2017. The meeting minutes are attached as Appendix A of this report for the information of the Board. Internal Audits Pursuant to the international ISO14001 EMS standard and the provincial DWQMS standard, periodic “internal” audits are performed by the Board’s administration to ensure continued compliance with legislated, contractual, and other requirements, as well as conformance with the ISO14001 EMS standard and DWQMS standard. Internal audits also ensure that the ongoing operation of the water supply system conforms to the EMS and DWQMS as implemented. As required by the standards, internal audits are performed a minimum of once annually. There were no internal audits conducted during this reporting period. External Audits Annual surveillance audits (third-party external audits) are conducted for both the EMS and DWQMS, with a recertification audit taking place every third year. The external registrar for both the EMS and DWQMS is currently SAI Global. External audits review all aspects of the EMS or DWQMS, including the internal audits, subsequent management reviews, and corrective action processes. There were no external audits conducted during this reporting period. Corrective and Preventive Actions For an EMS and DWQMS to be effective on an on-going basis, an organization must have a systematic method for identifying actual and potential non-conformities, making corrections and taking corrective and preventative action, preferably preventing problems before they occur. The internal audit process and management review are the two main drivers for identifying potential problems for the LHPWSS and implementing corrective actions. Preventative actions may originate from identified opportunities for improvement as part of an audit, but also staff suggestions and discussions with management.

The action items are currently 95% complete overall, which represents an improvement from the previous reporting period. The 10 overdue action items are all proactive in nature (not corrective) and generally relate to the following:

Implementing an electronic document management system (EDMS), with a follow-up item relating to investigating database software once this is implemented. The project is currently delayed due to coordination and licencing issues with Microsoft, but has since been resolved Implementation of the document system via Office 365 is projected to begin in the second quarter of 2017.

One action item is related to the recent HVAC project, specifically closing out an EMS/QMS checklist once all documentation is received.

Conducting a control system study to review the process control narrative and programming and recommend improvements. This study was approved as a 2016 capital project and is currently in progress.

Reviewing the existing operational and regulatory reports in SCADA and making recommendations for improvement.

Providing the plant operations staff with training on energy management. Board staff are currently working with a consultant on a training proposal.

Improving parking and access signage around the water treatment plant property. Conducting a risk assessment of fire alarm and smoke detection systems at the water treatment

plant. This is being looked at as part of the security assessment and audit currently taking place in 2017.

Two items relate to the transition to ISO14001:2015 standard and include a review of the Board’s guiding principles and strategic plan, and providing staff with an overview of the changes in the new version of the standard and the results of the gap analysis. Board staff are currently working with an external consultant to complete staff training so these items can be completed.

Changes from previous reporting period: Six (6) new proactive action items were added as a result of the January 31, 2017 Management

Review meeting.


File No. H17/2017


For reporting clarity, the table above will be updated on a quarterly basis to track completions and outstanding items. In addition, any changes which occurred from the previous reporting period will be specifically noted for the reference of the Board. PLAN-DO-CHECK-IMPROVE It should be noted that the “PLAN-DO-CHECK-IMPROVE” system required by the ISO14001 and DWQMS standards requires continuous monitoring of the EMS/DWQMS, with periodic review and audits conducted to demonstrate conformance. A key concept of this approach (Plan-Do-Check-Improve) is that it does not require or expect 100% conformance, but promotes an environment of continual review and improvement by identifying shortfalls, implementing corrective measures, and setting objectives and targets for improvement. The monitor, review and audit philosophy is integrated in not only the monitoring of the registered EMS and DWQMS, but also the Board’s contracted operations.

CONCLUSION

The internal audits and frequent management review meetings continue to effectively identify system deficiencies. The EMS and DWQMS for the Lake Huron Primary Water Supply System continue to be suitable, adequate and effective. Activities by OCWA continue to address the need for change, and the management systems are being revised and refined by OCWA as required. This report was prepared by Erin McLeod, Quality Assurance & Compliance Manager.

October 31, 2016

Comments Due January 9, 2017 Summary The proposed guideline is as follows:

“Where treatment is required for enteric protozoa, the proposed guideline for Giardia and Cryptosporidium in drinking water is a health-based treatment goal of a minimum 3 log removal and/or inactivation of cysts and oocysts. Depending on the source water quality, a greater log removal and/or inactivation may be required. Treatment technologies and watershed or wellhead protection measures known to reduce the risk of waterborne illness should be implemented and maintained if source water is subject to fecal contamination or if Giardia or Cryptosporidium have been responsible for past waterborne outbreaks.”

Notes The existing guideline was last updated in 2012. The document proposes to reaffirm the guideline as a health-based treatment goal of a minimum 3 log removal and/or inactivation of cysts and oocysts for enteric protozoa (Giardia and Cryptosporidium) in drinking water.

Source MOECC Date Posted/ Notice Received

December 19, 2016

Comments Due N/A Summary The amended regulations will be in force on July 1, 2017. The exception is

the new requirement for laboratories to submit to the MOECC results from all drinking water tests for which they are licensed to analyze comes into effect on January 1, 2018. Changes to O.Reg. 169/03 (Ontario’s Drinking Water Quality Standards): Three new drinking water quality standards based on new federal guidelines will be introduced: • 0.06 mg/L for Toluene; • 0.14 mg/L for Ethylbenzene; and • 0.09 mg/L for Total Xylenes Two drinking water quality standards will be revised: • From 0.01 mg/L to 0.05 mg/L for Selenium; and • From 0.03 mg/L to 0.01 mg/L for Tetrachloroethylene. One drinking water standard, which is a sum of nitrate and nitrite, will be removed. Consequently, the following drinking water quality standard will be removed: • 10 mg/L for Nitrate + Nitrite. Changes to the MOECC’s Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines: One new Aesthetic Objective will be introduced: • 0.015 mg/L for methyl t-butyl ether (MTBE). Two Aesthetic Objectives will be revised: • From 0.0024 mg/L to 0.0016 mg/L for ethylbenzene; and • From 0.3 mg/L to 0.02 mg/L for xylenes. Changes to O.Reg. 170/03 (Drinking Water Systems): All pesticides found at levels above 100 nanograms/Litre (ng/L) will initiate an AWQI. This includes pesticides that are not in Schedule 2 of O. Reg. 169/03 and currently do not have a drinking water standard in place.

All test results that indicate the presence of pesticides – even if their concentration levels are at or below the threshold of 100 ng/L – will need to be provided to the ministry.

Municipal and non-municipal drinking water system owners will no longer be required to submit lead testing summary reports to the ministry, as the same information will have to be included in the system’s annual report which is required to be made available to the public.


File No. H17/2017


Additionally, the following general changes and corrections to the regulation have been made:

List of control documents to be recognized by laboratories now include ‘municipal drinking water licence’ where it was omitted.

‘Sound’ has been replaced by ‘signal’ when referring to the requirement for an alarm to sound when there is a problem at the system.

Wording has been added to indicate that non-municipal residential systems that receive all their water from another regulated drinking water system and do not re-chlorinate water are not required to prepare Engineering Evaluation Reports.

Wording has been clarified around the calculation of Running Annual Averages (RAAs) for situations where tests are only required once every three years.

Changes to O.Reg. 128/04 (Certification of Drinking Water Operators and Water Quality Analysts): Requirements for Drinking Water Operator-in-Training (OIT) Certification have been updated as follows:

Temporary Drinking Water OIT certificates will cease to be issued. Drinking water OIT certificates will be valid for 36 months. Drinking water OITs will be permitted to operate Limited Systems

under the supervision of an Operator-in-Charge or Overall Responsible Operator.

The changes to O.Reg. 243/07 (Schools, Private Schools and Day Nurseries) and O.Reg. 248/03 (Drinking Water Testing Services) do not impact the LHPWSS and EAPWSS.

Notes Action Item: Denny Rodrigues to update the quarterly water quality reporting template once the regulatory changes take effect. The Q3, 2017 report will be the first one affected by the changes. Deadline: October 31, 2017 Action Item: Erin McLeod to review the WaterTrax alert settings once the regulatory changes take effect. Update alert settings as necessary to reflect the changes in the water quality parameters. Deadline: October 31, 2017 Title Notice: Canadian Environmental Protection Act, 1999 – Notice with

Source Canada Gazette Date Posted/ Notice Received

December 10, 2016

Comments Due N/A – Consultation in 2017 Summary The proposed expansion to the reporting requirements includes:

lowering the reporting threshold from 50,000 to 10,000 tonnes of carbon dioxide (CO2) equivalent. All facilities that emit the equivalent of 10,000 tonnes or more of greenhouse gases (GHGs) in CO2

equivalent per year will be required to submit a report; reporting of additional data (e.g. more detailed emissions, quantities

of fuels or feedstocks consumed, etc) and applying specific quantification methods to determine emissions.These new requirements will be gradually phased in by sectors.

ECCC will begin consultations with stakeholders in early 2017, in advance of issuing requirements for 2017.

Notes Sources of greenhouse gases are categorized as stationary fuel combustion, industrial process, venting, flaring, fugitive, on-site transportation, waste and wastewater. The changes should not impact the LHPWSS and EAPWSS.

Title Proposed Guideline Technical Document on Lead in Drinking Water Source Health Canada Date Posted/ Notice Received

January 11, 2017

Comments Due March 15, 2017


File No. H17/2017


Summary “The existing guideline for lead, last updated in 1992, based its maximum acceptable concentration (MAC) of 0.01 mg/L (10 µg/L) on a provisional tolerable weekly intake of lead established by the World Health Organization (WHO) at a level that showed no increase in blood lead levels and thus no expected increase in health risks. This new document identifies reductions in IQ as the critical effect of lead, with a proposed MAC of 0.005 mg/L (5 µg/L) based on analytical achievability. It provides updated data and information related to exposure to lead in Canada, to analytical methods and to treatment approaches available at the municipal and residential scales. Based on these considerations, the document proposes a MAC of 0.005 mg/L for total lead in drinking water.” Proposed Guideline: “A maximum acceptable concentration (MAC) of 0.005 mg/L (5 µg/L) is proposed for total lead in drinking water, based on a sample of water taken at the tap and using the appropriate protocol for the type of building being sampled. Every effort should be made to maintain lead levels in drinking water as low as reasonably achievable (or ALARA).”

Notes If in future Ontario follows the recommendations of Health Canada and also adopts a lowered MAC for lead at 5 ug/L, this could trigger additional Ontario municipalities to have to implement corrosion control plans (CCP). Currently City of London has already implemented a CCP in partnership with the LHPWSS.

Action Item: Erin McLeod to highlight this item in the text of the next quarterly compliance Board Report, for the information of the Board. Deadline: March 9, 2017. 3. Huron & Elgin: Results of Board Meetings – December 1, 2016 December 1, 2016 Huron Board Meeting Quarterly Compliance Report: Staff addressed water quality questions related to the aluminum objective of 0.1 mg/L (to be clarified in future reporting that the objective is actually <0.1 mg/L), and pH fluctuations. EMS/QMS Report: Staff addressed a question regarding the moratorium on new water bottling facilities; The LHPWSS would not sell water directly to a large industrial/commercial facility, as they would be a customer of a member municipality. MOECC Inspection Report: Regarding the recent inspection rating of 100%, good job. December 1, 2016 Elgin Board Meeting EMS/QMS Report:


File No. H17/2017


Regarding the 9 overdue items noted in the corrective action summary, the Board asked when they can expect these to be addressed. Staff anticipates many of these action items will be completed by March 2017. The status of the 9 outstanding action items was reviewed. The Board would like an update on these in future to ensure they were all completed. At management review there was a suggestion to look at the way the data is being reported (eg. % overdue versus % incomplete). There was a question regarding the numbering in the management review meeting minutes and why they are not in sequential order. Because it is a combined management review for both Huron and Elgin, to shorten the report only the items related to Elgin are included in the Board report. At management review there was a staff suggestion to keep the numbering, noting “Huron item” or “Elgin item” but without the specific details, to keep the number sequential. Quarterly Compliance Report: General comment that the report contains lots of charts and analysis (related to water quality), and the Board wants to be sure they are focusing on the right things. At a future meeting they would like further explanation. Staff suggested a voluntary session (for both Boards) to go over the water quality tables and provide explanation. 4. Huron & Elgin: EMS Objectives Current objectives: The objectives expire July 1, 2017 so a review of the current status of all objectives and targets was completed in preparation for setting new objectives and targets. Handouts: Electricity consumption trends, chemical consumption trends, and process water trends (Fall 2012 – Fall 2016) were reviewed, as well as other data from the Key Performance Indicator (KPI) spreadsheets maintained by RWS. The status of the current objectives, targets and programs was provided. Overview summary:

Elgin energy efficiency: quarterly average 642.5 kwh/ML Huron energy efficiency: quarterly average 830.0 kwh/ML Elgin chemical efficiency: quarterly average 88.6 Kg/ML; average from summer 2014 – fall 2016

(after the pH target was adjusted) was 78.7 kg/ML Huron chemical efficiency: quarterly average 50.0 kg/ML Elgin process water: quarterly average 5.98% Huron RMF: Objective and target fully achieved Elgin RMF: Objective and target not achieved yet as commissioning is underway. Huron & Elgin waste oil: Intent to reduce unnecessary waste oil is being achieved.

For Huron objective/target #4 and Elgin objective/target #5 related to the reduction of waste oil, it was recommended that these be closed out and not carried forward into future objectives/targets. The oil sampling/analysis prior to removal has now become a standard operating procedure. OCWA has worked this into their regular operations so no need to specifically track. Huron objective/target #3 related to residuals management can now be closed out. The RMF has been operating since 2013 and the target and regulatory requirements are being met. If there are any issues


File No. H17/2017


going forward this will be dealt with at the monthly operations meetings. Monitoring of the total chlorine residual and total suspended solids will continue, as this is a requirement of the MDWL. Elgin objective/target #3 related to process water will be closed out as this is not a significant aspect. Staff will continue to track this is a key performance indicator (KPI), monitor progress and make improvements where possible. The objectives/targets related to electricity and chemical consumption will carry forward as there are more opportunities available. New Objectives: Draft objectives/targets/programs were discussed.

Huron objective #1 relates to electricity consumption. Huron objective #2 relates to chemical consumption. Elgin objective #1 relates to electricity consumption. Elgin objective #2 relates to chemical consumption. Elgin objective #3 relates to residuals management.

The target years for all objectives were set at July 1, 2017 – December 31, 2022 to coincide with the 5 year operating term extension with OCWA. The new targets and baselines were set by factoring in a review of the data from the past 4 years (Fall 2012 – Fall 2016), taking into account the quarterly average, direction of the trending, and anticipated changes in the next few years. The draft programs were reviewed and staff and top management provided comments and requested changes. The comments will be incorporated into finalized programs and presented to the Board at the upcoming March 9, 2017 meeting for approval. 5. Huron & Elgin: Staff Suggestions Huron & Elgin – Training Suggestion from an RWS staff member that all new staff should be given a basic water treatment training session, similar to what OCWA provides all new staff, as not everyone has a background in water treatment. OCWA has a series of corporate videos available (eg. “Bird’s Eye View of Water Treatment”). OCWA can make arrangements for videos to be available for RWS staff upon request. Huron – Polymer Trial OCWA suggestion to trial a dry polymer in the RMF. Currently liquid polymer is used. There are limited options for hydrocarbon-free liquid polymers and it’s expensive. To expand options OCWA is working with Brenntag on setting up a trial. Brenntag may be able to supply equipment needed to conduct a trial. This is being looked at for spring 2018. Huron & Elgin - Building Envelope Energy Surveys


File No. H17/2017


OCWA is recommending building envelope energy surveys be conducted to identify energy loss through heating and cooling. Blair Tully provided an email with details on January 7, 2017 along with a sample report. OCWA is currently obtaining pricing and will bring forward a proposal to RWS for consideration. An energy expert from OCWA is looking at rebates on natural gas. Inspection/survey would be done by a consultant (Tremco). The method used is IR and smoke. Both plants have had HVAC upgrades, the next step is optimization (eg. sealing). This project would relate back to the EMS objectives of energy reduction. Huron & Elgin – Natural Gas Tracking Staff would like to create a key performance indicator (KPI) to start better tracking natural gas consumption. This is a significant aspect and usage has increased at Huron after the HVAC upgrade (natural gas boilers and dehumidifiers added). Action Item: Erin McLeod to create KPIs to track natural gas consumption. Monitor monthly consumption and also look into normalizing the data to the average monthly temperature. Deadline: July 1, 2017 6. Huron & Elgin: QMS – Deviations from Critical Control Points (2016 Summary) Handouts: WaterTrax Alert Action Reports were generated for 2016. This provides a summary of all WaterTrax alerts received in 2016. Huron: Total of 22 alerts received. The alerts were reviewed. No changes are required to the alert settings at this time. Operators will be reminded to enter in comments if an alert is going to be generated. Elgin: Total of 198 alerts received. The majority of the alerts related to low settled water chlorine, likely as a result of the filter upgrade project. There is a future OFI to start looking into achieving better chemical mixing (for chlorine and fluoride especially). The high conductivity alerts were mainly received in March/April and attributed to spring runoff. The fluoride and pH alerts can mainly be attributed to the twinned pipeline operations and pipeline switching. The fluoride and caustic chemical systems are shut off prior to pipeline switching and back on when the plant reaches steady state again. At this time no changes are recommended to the alert settings. In future if we can address the twinned pipeline operations and eliminate the need for pipeline switching the number of pH and fluoride related alerts will be reduced. 7. Elgin RMF – Impacts to System and Updates Required A Management of Change Form was completed to capture the changes required to the EMS/QMS as a result of the RMF operation. This should have addressed most items such as updating procedures to include sampling, chemical handling, chemical deliveries etc. Top management is requesting that further review be conducted for all EMS/QMS procedures to ensure any changes as a result of the RMF are documented properly. Action Item: Denny Rodrigues and Erin McLeod to complete a review of all EMS/QMS procedures to ensure RMF details are documented as required. Complete this review for both Elgin and Huron. Deadline: July 1, 2017.


File No. H17/2017


8. Huron & Elgin: Status of Previous Action Items Handout: A summary of all incomplete action items was provided for review. Current action item completion status as of January 30, 2017:

Huron 91% complete Elgin 90% complete

Staff will further update the spreadsheets this week prior to the next Board reporting deadline. The % completion should slightly improve as several more action items are anticipated to be completed.

Subject: Environmental Objectives

RECOMMENDATION

That the following actions be taken by the Lake Huron Primary Water Supply System Board of Management with respect to the environmental objectives:

a) The Board of Management for the Lake Huron Primary Water Supply System RECEIVE this report for information; and

b) The Board of Management for the Lake Huron Primary Water Supply System ENDORSE the environmental objectives as outlined in this report.

PREVIOUS REPORTS

December 5, 2013 Environmental Management System Objectives and Targets August 4, 2011 Environmental Management System Objectives and Targets December 10, 2009 Environmental Management System Objectives and Targets October 9, 2008 Environmental Management System Objectives and Targets June 8, 2006 Environmental Management System Objectives and Targets

BACKGROUND

Environmental Management System

An ISO 14001 Environmental Management System (EMS) requires that an organization establish environmental objectives. An environmental objective is an environmental result that the organization intends to achieve over the course of an established period. The environmental objectives must take into account the organization’s significant environmental aspects and associated compliance obligations, as well as consider its risks and opportunities. The ISO 14001 standard requires that environmental objectives must be:

a) consistent with the environmental policy; b) measurable (if practicable); c) monitored; d) communicated; and, e) updated as appropriate.


File No. H17/2017


The standard also requires that an organization implement planning actions to achieve the environmental objectives. An organization must determine what will be done, what resources will be required, who will be responsible, when it will be completed, and how the results will be evaluated including indicators for monitoring progress toward achievement of the measurable environmental objectives. Collectively these planning actions are referred to as the program. Current Environmental Objectives At the Board meeting of December 5, 2013, the Board endorsed the following objectives and targets for the Lake Huron Primary Water Supply System (LHPWSS): Objective #1: Reduce the demand on the Provincial electrical generation and transmission system through conservation and displacement efforts. Target Years: January 1, 2013 - July 1, 2017 Target and Baseline: <750 kWh/ML on a quarterly basis

Objective #2: Reduce the use of chemicals in the production of treated potable water. Target Years: January 1, 2013 - July 1, 2017 Target and Baseline: <50 kg/ML on a quarterly basis

Objective #3: Reduce the amount of residue materials being returned to the receiving water body (Lake Huron) as a result of water treatment processes. Target Years: January 1, 2013 - July 1, 2017 Target and Baseline: <25 mg/L average total suspended solids and non-detect total chlorine residual on a quarterly basis

Objective #4: Reduce the amount of waste oil generated at the LHPWSS. Target Years: January 1, 2013 - July 1, 2017 Target and Baseline: <250 L of waste oil on an annual basis

The objectives and targets established for the area water system related to four general but significant environmental aspects; electricity consumption; chemical consumption; discharges to the lake; and disposal of hazardous waste (waste oil). Efforts to meet these objectives and targets did not affect the quality of water produced at the water treatment facility or create additional risk.

DISCUSSION Results - Current Environmental Objectives At a Management Review meeting held on January 31, 2017, top management (the Board’s Manager of Regional Water Supply and OCWA’s General Manager), the “EMS Representative” and other staff reviewed the status of the current environmental objectives and targets.


File No. H17/2017


Objective #1: The objective to reduce the demand on the Provincial electrical generation and transmission system through conservation and displacement efforts is not currently being achieved. Electricity consumption is tracked for the Lake Huron Water Treatment Plant (WTP) and McGillivray Pumping Station (PS). The quarterly average electricity consumption for the previous four year period (Fall 2012 – Fall 2016) was 830.9 kwh/ML which is significantly higher than the target of 750 kwh/ML. The overall trend is improving over time.

For future environmental objectives, it is recommended that the Board continue to pursue an objective related to electricity consumption as there are further opportunities to improve this trend. It is recommended that separate targets be identified for the Lake Huron WTP and McGillivray PS in order to better assess the effectiveness of the programs at each of these facilities. Objective #2: The objective to reduce the use of chemicals in the production of treated potable water is currently being achieved. The quarterly average chemical consumption for the previous four year period (Fall 2012 – Fall 2016) was 50.0 kg/ML which is right at the target of 50 kg/ML. The overall trend is improving over time.


File No. H17/2017


For future environmental objectives, it is recommended that the Board continue to pursue an objective related to chemical consumption as there are still further opportunities to improve this trend. It is recommended that the target be lowered as staff feels that this is achievable. Objective #3: The objective to reduce the amount of residue material being returned to the receiving water body (Lake Huron) as a result of the treatment process was reviewed. The Lake Huron Residue Management Facility (RMF) was fully commissioned and began operating in 2013. The target and regulatory requirements for this facility are currently being met. If there are any operational issues going forward this will be discussed at the regular monthly operations meetings with the operating authority. Monitoring of the total chlorine residual and total suspended solids will continue, as this is a regulatory requirement under the Municipal Drinking Water Licence (MDWL). It is recommended that this environmental objective be closed out as it has been achieved. Objective #4: The objective to reduce the amount of waste oil generated was not achieved. The annual average amount of waste oil disposed of between 2013 and 2016 was 467 L/year which is higher than the target of 250 L/year.


File No. H17/2017


Upon further review, it is thought that the initial target set in 2013 may have been too ambitious. The operating authority has now implemented a standard operating procedure in which regular oil sampling/testing is conducted to monitor the oil condition. This analysis has optimized the oil change frequency as oil changes are now based on oil condition and quality as opposed to a set time frequency. It is recommended that this environmental objective be closed out, despite not meeting the target, as the operating authority has optimized the amount of waste oil being generated by the system. Staff will continue to monitor the amount of hazardous waste generated, including waste oil, however this will not be formally documented as part of the Environmental Management System (EMS) environmental objectives. An objective may be reviewed in future once the implications of the new waste oil program has been assessed. Proposed New Environmental Objectives As a result of the January 31, 2017 Management Review meeting, it is recommended that two environmental objectives be carried forward, with updates as follows: Objective #1: Reduce the demand on the Provincial electrical generation and transmission system through conservation and displacement efforts. Target Years: July 1, 2017 – December 31, 2022 Target and Baseline: Huron Water Treatment Plant: <700 kWh/ML measured on a quarterly basis McGillivray Pumping Station: To Be Determined, following data download and review of current trends

Objective #2: Optimize the use of chemicals in the production of treated potable water and associated residuals treatment. Target Years: July 1, 2017 – December 31, 2022 Target and Baseline: <48 kg/ML on a quarterly basis

A full description of the proposed LHPWSS environmental objectives, targets and programs can be found in Appendix C of this report for the information and reference of the Board. The new target dates of July 1, 2017 through December 31, 2022 coincide with the Operating Authority’s proposed extended 5 year contract renewal term. The new targets and baselines were set by factoring in a review of the data from the past four years (Fall 2012 – Fall 2016), taking into account the quarterly and seasonal averages, direction of the trending, and anticipated system changes in the next few years which might influence the targets (either positively or negatively). Efforts to meet these objectives and targets will at no time affect the quality of water produced at the water treatment facility or create additional risk to the system. In order to achieve the programs identified in Appendix C, any related capital projects or recommended process changes to the water treatment system would be presented to the Board for approval, and


File No. H17/2017


would include a complete business case identifying costs and/or savings, resource requirements and anticipated impacts. Board staff may make periodic minor amendments/updates to the associated programs where appropriate. Any significant changes, including changes to the environmental objective or target, will be presented to the Board for approval.

CONCLUSION An ISO 14001 EMS requires specific and measurable environmental objectives to be periodically established by an organization in order to meet the requirements of the organization’s environmental policy. Further innovation and optimization efforts on behalf of the Operating Authority and the Regional Water Supply are still required in order to meet the environmental objectives.

Subject: Capital Status Report

RECOMMENDATION

That the following actions be taken with regard to Lake Huron Primary Water Supply System capital projects:

a) That this report regarding the status capital projects BE RECEIVED for information;

b) That project LH1013 Financial Plan and LH1223 WTP Fire Damage Repairs BE CLOSED, with the surplus funds in the approximate amount of $25,197 released to the Board's Reserve Funds; and,

c) That projects LH1305 Transmission Pipeline Twinning BE CLOSED, it being noted that the corresponding projected debenture issuance related to these projects will be reduced accordingly and surplus funds (if any) released to the Board’s Reserve Funds.

DISCUSSION

The Capital Project Status Report, attached to this report as Appendix A for the Board's information, provides a brief overview of the status of current capital projects for the Lake Huron Primary Water Supply System. This report is provided for the general information of the Board.

The status report is divided into four categories of projects, namely:

1. Ongoing Projects: This section provides a summary list of all projects which are funded by the Board through the Capital Budget and which are currently in-progress. Board funded projects are typically for the replacement or upgrade of existing assets, the construction of new assets, or engineering studies and assessments, as approved by the Board.

Under the terms of the Service Agreement with the contracted operating authority, the Board is also required to pay for some maintenance/repair projects. The benchmark used in the operating contract is that if the value of the material and any contracted labour is over $30,000, the project is considered Capital Maintenance and the contracted operating authority would fund the first $30,000, with the balance funded by the Board. Accordingly, the Board maintains an annual “fund” within the Board’s capital budget to pay for these projects as they arise.


File No. H17/2017

Report Page 2 of 5 March 9, 2017 Capital Project Status Report

2. Completed Projects - Release Surplus to Reserve Funds: This section provides a summary list of all projects which are presently completed, but do not require additional funds from that budgeted. Should the Board approve the closure of the listed projects, it is the recommendation of staff to release the surplus funds, if any, to the Reserve Fund.

Completed Projects – Reduce Debenture: In the case where the project is funded through the issuance of a debenture, should the Board approve the closure of the listed project it is the recommendation of staff to reduce the previously projected and corresponding debenture for the project(s).

3. Completed Projects - Additional Funding Required: This section provides a summary list of all projects which are presently completed, but require additional funds from that originally approved. Should the Board approve the closure of the listed projects, it is the recommendation of staff to provide the required additional funding from the Board’s Reserve Fund.

In addition to the projects previously approved in the 2017 Capital Budget, one additional project was initiated by administration pursuant to the Board’s Procurement Policy:

LH1225 Transmission Pipeline Repair – Following the condition assessment and installation of the Acoustic Fibre Optic Monitoring System on the 1200mm diameter high pressure reinforced concrete transmission pipeline in 2015, it was discovered that pipe #32-48 located near Elginfield Road (Middlesex County Road 7) in North Middlesex had deteriorated to unacceptable levels and posed a high risk of failure. In December 2016, Board administration approved the proactive replacement of this pipe segment in accordance with the Board’s Procurement Bylaw. The proactive replacement of this deteriorated pipe was completed on February 15th, 2017, and final reinstatement of the property affected is scheduled to be completed in the spring.

Report Page 1 of 3 March 9, 2017 Distressed Pipe 32-48 Replacement Project




Subject: Distressed Pipe #32-48 Replacement Project

RECOMMENDATION

That the Board of Management of the Lake Huron Primary Water Supply System RECEIVE this report regarding the Distressed Pipe #32-48 Replacement for information.

PREVIOUS AND RELATED REPORTS

March 21, 2013 Huron Transmission Main Condition Assessment and Leak Detection – Pipeline A Inspection Results

June 12, 2014 Huron Primary Transmission Main Acoustic Fibre Optic Monitoring System Project

March 5, 2015 Huron Primary Transmission Main Acoustic Fibre Optic Monitoring System Project

BACKGROUND

In March 2013, it was reported to the members of the Board of Management for the Lake Huron Primary Water Supply System that staff completed the condition assessment of the 1200mm (48 inch) reinforced concrete pressure pipe which was originally constructed in the 1960’s. The condition assessment utilized both leak detection as well as non-destructive electro-magnetic technology to assess the current state of this now fifty year old pipeline, and found that the majority of the pipeline is in generally good condition.

As part of the Acoustic Fibre Optic monitoring system project that was commissioned in July 2015 by Pure Technologies, however, the LHPWSS determined in late 2016 that a pipe in an un-twinned high pressure section of the LHPWSS transmission main approximately 600 metres south of Elginfield Road (Middlesex County Road 7) was in poor condition and consequently at high risk of failure. On this basis, with the concurrence of LHPWSS’ contracted operating authority (OCWA) and Pure Technologies, Board staff initiated the proactive replacement of this pipe section.


File No. H17/2017


DISCUSSION

Procurement The activities of the regional water systems are undertaken under the authorities granted under the Transfer Order issued by the Province of Ontario, and subsequent bylaws and policies of the Board of Management. Notwithstanding, the LHPWSS is entitled to use the City of London’s policies and procedures as a guide. The procurement of the necessary services to complete the works are within administrative authority under the Order and bylaw, however for transparency and aid in the utilization of City of London’s resources (including the City of London’s Purchasing Division), Board staff utilized the City of London’s procurement policy as a guide in procuring the services necessary to complete the urgent repair.

Specifically, Board staff utilized a single source procurement to complete the project. The justification for the single source procurement was attributed to the particular Contractor, L82 Construction Ltd. (L82) having the special knowledge, skills, expertise and experience replacing pipe sections of this size, nature and operating conditions, in un-twinned sections of the LHPWSS transmission main. This is in keeping with section 14.4(e) of the City of London’s Procurement of Goods and Services Policy which is used as a guide by the LHPWSS. It is noted that L82 is the only contractor that has completed these type of repairs on behalf of the LHPWSS. L82 also has direct familiarity with the transmission system having recently completed the pipeline twinning construction project in 2014 just north of pipe section 32-48. Upon review of L82’s quotation it was found that the rates are comparable to the rates of the previous pipe replacements completed on the transmission main in 2013 and 2014.

With the approval of the Chief Administrative Officer, project number LH1225 was created for this urgent repair utilizing the Emergency Reserve Fund for the source of finance.

Proactive Repair The transmission pipeline repair operation began at 1:00am on Wednesday February 15, 2017 when the water treatment plant was shut down and crews isolated and drained the pipeline. By 9:30 am, crews had completed excavating the pipeline and started the process to cut out and remove the damaged pipe. The removal and replacement of the damaged pipe was completed, and the transmission pipeline was returned to service at 8:30pm on Wednesday February 15, 2017.

During this nearly 20 hour repair of the transmission pipeline, area municipalities relied upon treated water stored in reservoirs and elevated towers throughout the region. Due to the low system demands in the region, typical of this time of year, and the increased supply from the Elgin Area Primary Water Supply System into the City of London, the regional water system was able to recover and refill area reservoirs by noon on February 16, 2017; nearly 12 hours ahead of the anticipated schedule.

The costs associated with this unanticipated capital project were borne from emergency reserve fund, and total approximately $275,000 including engineering, construction and landowner compensation. The total expenditures associated with of the transmission main failure that occurred in 2012 were approximately $1.5 million.


File No. H17/2017


CONCLUSION

The LHPWSS determined that a pipe in an un-twinned section of the LHPWSS transmission main approximately 600 metres south of Elginfield Road was in poor condition and consequently at risk of catastrophic failure. On this basis, with the concurrence of OCWA and Pure Technologies, Board staff engaged the services of L82 Construction Ltd. to complete the proactive replacement of this pipe section on February 15, 2017 through a single source procurement.

Report Page 1 of 5 March 9, 2017 Regional Water Office and Divisional Restructuring




Subject: Regional Water Office and Divisional Restructuring

RECOMMENDATION

That the following actions be taken with regard to the Regional Water Supply Office and Divisional Restructuring:

a) That the Board of Management for the Lake Huron Primary Water Supply System ENDORSE the amendment to the lease agreement for the Regional Water Supply office at 235 North Centre Road to add approximately 729 square feet (rentable area) and extending the current lease to March 31, 2024; and,

b) That the Board of Management for the Lake Huron Primary Water Supply System ENDORSE the proposed changes to the positions and organization of the Regional Water Supply Division.


October 11, 2007 Regional Water Supply Reorganization

BACKGROUND

Under the Transfer Order issued by the Minister of the Environment in 2000, the City of London was designated the ‘Administering Municipality’ and required to provide all administrative services for the Lake Huron Water Supply System under the direction of its Board of Management. In order to facilitate this requirement, the City of London created the Regional Water Supply Division which is seconded to report to the Board and provide the necessary administrative and management services as required. Through this seconded Division, other services are procured to support the Board’s needs including such things as computer system network services, energy management, and legal services, for example.

In April 2010, the Division moved to its current location at 235 North Centre Road and currently occupies a space designated as “suite 200” of approximately 3,377 square feet (rentable area). The current lease, which expires on March 31, 2020, includes provisions for two term extensions of 5-years each as well as a first right of refusal of any contiguous space.


File No. H17/2017


DISCUSSION

Office Space Over the course of the last seven years, the Division has been adjusted in its complement in order to support the needs of the water supply system, and a meeting space has been converted to an office and storage area. As the Division prepares to support the long-term initiatives of the regional water system, it has been confirmed that additional space is required.

Staff were notified by the current landlord that an adjoining space, measuring approximately 729 square feet of rentable area, will become available effective May 1, 2017. In accordance with our current lease agreement, the Division office can be expanded to include this space at the same terms and conditions until March 2020.

The lease rate paid for the current office space is $11 per square foot, and is considered to be below “market value” given the location and building condition.

The proposed amending agreement would extend the lease agreement term an additional four years (to March 2024) and add the additional office space, as identified in Appendix A of this report. The lease rate would remain at the current rate of $11 per square foot until April 1, 2020, at which point it would marginally escalate to market rate in two stages (Aril 2020 to March 2022, and April 2022 to March 2024) to a market value of $14.50 per square foot. The amending agreement would also allow for one additional lease extension of five year.

Given the value and terms of the proposed amending agreement, it is the recommendation of Board staff to proceed with the addition of the adjoining space to the current office. The addition of this space also allows for the opportunity for a more efficient office layout.

Divisional Organization The current organization of the Division is centred on the services required as identified more than fifteen years ago. With the recent approval of the new Asset Management Plan, the Customer Level of Service and Risk Mitigation framework, the Financial Plan, and the Master Water Plan (including the Water Quality Facility Plan), the focus of the Division needs to further evolve to better include asset management, communications and financial aspects of the administration of the system.

The in order to address the current and pending needs of the regional water supply system, the major areas of focus are:

Engineering: There are currently two professional engineers, one technologist, and one 12-month intern student dedicated to this. These positions primarily are utilized to undertake long-term studies, engineering assessments, and research related to treatment efficiency and efficacy, as well as the design, construction and integration of new assets and processes.

Operations: There is currently one manager and one control systems coordinator (SCADA technologist) dedicated to this. These positions primarily are responsible for the oversight of operation and maintenance activities of the regional water supply system, the coordination of the operational activities between the Board’s contracted operating authority (OCWA) and the fifteen municipalities (including those in the Elgin Area Water System), and the ongoing monitoring, maintenance and upgrade of the Supervisory Control and Data Acquisition (SCADA) system.


File No. H17/2017


Quality Assurance and Compliance: There is currently one manager and one coordinator dedicated to this area. These positions are responsible for oversight, monitoring, auditing, reporting, and coordination of corrective actions related to the system’s compliance with Provincial and Federal legislation, adherence to provincial standards and protocols, monitoring of contractual obligations of the contracted operating authority to the regional water system, and monitoring of contractual obligations of the regional water system with other stakeholders (including the benefiting municipalities).

Business Administration: There are two positions dedicated to this area. The Division Manager provides oversight and approval authority to the entire operation, as well as such things as monitoring and approvals related to revenue and expenditures, adherence to policy, and recommendations to the Chief Administrative Officer and the Board related to governance and policy revision. In support of these activities, a Divisional Administrative Assistant (currently vacant) provides or coordinates additional services necessary for the business function of the Division.

To address the current and future needs of the Division and the regional water system, the following changes are recommended:

Add a communications coordinator position responsible for the management, installation, programming and coordination of the regional water system’s network communications, including the SCADA-Virtual Private Network, Voice-over-IP communications, and other business-related networks. This position would also manage the monitoring of communications systems and network security. This position is necessary given the complexity and specialization requirements of the computer network and support systems being employed in the regional water system.

Add an asset management coordinator position responsible for the management, monitoring, and analysis of asset-related data, the collection and utilization of asset condition assessments, analysis of asset data, and prepare recommendations related to the refurbishment and/or replacement of assets. This position would also:

o Maintain, monitor and coordinate the computerized maintenance management system, including naming conventions, tagging, and recording of required maintenance history

o Analyze data related to asset conditions, maintenance history, asset performance, SCADA, and energy/resource consumption

o Assist in the preparation of business cases related to asset refurbishment and replacement for the development of capital budgets and capital programs

o Assists in the preparation of treatment and operations optimization reports. Add a business manager position responsible for managing and coordinating the financial

business of the regional water systems. The position would undertake various financial and business-related activities including tendering and obtaining quotations for services, accounts payable, accounts receivable, accounting / budget analysis and monitoring, and liaise with the Financial Services group of the City of London in the preparation of annual budgets, year-end financial accruals and audits, and Tangible Capital Asset reporting.


File No. H17/2017


Delete the Administrative Assistant position, which is currently vacant, as much of the support requirements will be significantly reduced with the planned implementation of the Office 365 Network environment and otherwise addressed as part of the proposed reorganization.

The organization of the division is intended to avoid “silos” and ensure a better integrated approach to the activities of the regional water supply division. The administration is currently well organized, however to address the evolving needs of the regional water system it is recommended that these changes be implemented.

CONCLUSION

The pending availability of additional office space affords the opportunity to better rationalize the organization of the Regional Water Supply Division to address the long-term needs of the regional water system. It is the recommendation of Board staff that the addition of office space and organizational changes within the division proceed without delay.

Report Page 1 of 2 March 9, 2017 Emergency Chlorine Shut-off Actuators




Subject: Emergency Chlorine Shut-off Actuators

RECOMMENDATION

That the Board of Management of the Lake Huron Primary Water Supply System AUTHORIZE the creation of a capital project for the supply and installation of Emergency Chlorine Shut-off Actuators at the Lake Huron water treatment plant in the amount of $190,000, to be funded from the Capital Reserve Fund.


None

BACKGROUND

Inspectors from Environment and Climate Change Canada (ECCC) conducted an inspection of the Lake Huron water treatment plant on November 23, 2016, as it relates to the Fisheries Act, Canadian Environmental Protection Act and related regulations. As the water treatment plant discharges to Lake Huron and utilizes hazardous substances (chlorine), the focus of the inspection was largely related to the quality of the discharge from the plant drain to Lake Huron, and the storage and handling of liquefied chlorine gas.

DISCUSSION

The inspectors from Environment and Climate Change Canada were generally satisfied with the quality of the discharge from the plant drain, largely as a result of the implementation of the Residuals Management Facility, and satisfied that the license conditions from the Ontario Ministry of the Environment and Climate Change for the operation of the RMF satisfied their discharge criteria. Notwithstanding, concerns were expressed with regard to the storage and emergency response protocols related to chlorine.

The chlorine building has a chlorine scrubber system integrated into the air handling system for the storage containment room. In the event of a leak of an active chlorine cylinder, the chlorine scrubber would be activated, the chlorine gas vented into the storage room would be evacuated to the scrubber, and the chlorine neutralized. The chlorine scrubber has the capacity of handling up to one tonne of chlorine.

Each cylinder contains one tonne of chlorine, and at any given time there are three cylinders being utilized (“duty” cylinders) and three cylinders connected on stand-by. In addition, there can be up to an additional six to nine cylinders in storage racks on average and may be full or empty. When the three duty cylinders are empty, the chlorination system automatically switches over to the cylinders on stand-by, and the operators can change out the empty cylinders.

For the most part, the chlorination system and chlorine scrubber is original to the plant construction. The emergency chlorination scrubber system is designed to address the leak of one chlorine cylinder that is on duty or on stand-by as it would be more likely that a leak would occur at the point of connection to the cylinder. Cylinders in storage are protected and stored in the same condition as when transported to the facility.

It is less likely that a leak would occur on the manifold that connects all the duty and stand-by cylinders to the chlorination system, as the connection piping is replaced and manifold inspected frequently. Notwithstanding, the ECCC inspectors were concerned that an accidental damage of the connecting pipe or the manifold would subsequently result in the release of up to three tonnes of chlorine gas; triple the capacity of the scrubber system.

As a result, Environment and Climate Change Canada has issued a verbal warning for the Lake Huron Water Supply System to address this apparent risk, and will issue a formal warning letter or Order if immediate actions are not taken.

Upon review of the concerns expressed by the inspectors, Board staff recommends the immediate installation and integration of emergency shut-off actuators for each duty and standby chlorine cylinder. A similar system was implemented at the Elgin Area water treatment plant, as that system does not have a chlorine scrubber, and the ECCC inspectors were satisfied with that installation.

The emergency shut-off actuators are connected directly to the active cylinder, between the cylinder valve and the manifold. If a leak is detected within the storage room, all active cylinders are closed and isolated regardless if they are the source of the leak. This ensures that in the event of a leak on the manifold, a minimal amount of chlorine is vented to the room.

Based on comparative pricing for the installation undertaken at the Elgin Area facility, the estimated cost of undertaking this installation at the Lake Huron water treatment plant is $190,000.

CONCLUSION

In order to expeditiously address the issues identified and verbal warning issued by Environment and Climate Change Canada, and avoid a subsequent order and potential fine, it is the recommendation of Board staff that emergency shut-off actuators be installed on the chlorination system for the Lake Huron water treatment plant.

Report Page 1 of 2 March 9, 2017 LH1222 Low Lift Pump Rebuild Project




Subject: LH1222 - Low Lift Pump Rebuild Project

RECOMMENDATION

That the Board of Management of the Lake Huron Primary Water Supply System AUTHORIZE the increase in the approved Budget for Project LH1222 Low Lift Pump Rebuild to $270,000, it being noted that the Asset Replacement Reserve fund will be utilized for the source of funding.

BACKGROUND

In the 2016 Capital Budget, the Board approved the rebuild of the low lift pump and Motor #4, which would be undertaken through the Board’s contracted operating authority, the Ontario Clean Water Agency (OCWA). This rebuild, in part, includes a replacement of the original motor and an overall reconstruction of all mechanical parts, essentially returning the pump assembly to near-original condition.

In July 2016, OCWA submitted the documentation and cost estimate for this major maintenance project and was administratively approved by Board staff in August 2016 with a budget of $150,000, noting that OCWA was responsible for $31,795.51 of the overall cost in accordance with the Service Agreement. In the subsequent months, OCWA has been preparing the tender documents to award the work to a sub-contractor that met their bid requirements.

In the interim, during routine maintenance and inspection undertaken by OCWA, issues with the adjacent motor for Low Lift Pump #3 were identified. Both motors (#3 and #4) are identical and original to the plant. Since the 1980’s, these motors have been powered via a variable frequency drive (VFD) despite not being originally designed for VFD compatibility. This VFD has now been removed as part of Project LH1332 – Lake Huron Electrical System Upgrades and the pumps are currently running at a fixed speed as originally designed. As a result of the operating conditions since the 1980’s, the windings are now failing and Motor #3 is in need of replacement as it has reached the end of its service life.

DISCUSSION

Since OCWA was already in the process of ordering a motor related to the repair of Pump #4 it was determined that adding another motor to the order would help reduce overall costs and time by not having to repeat the ordering process and ensuring identical pumps are provided. The coincident order would also mitigate the risk of failure of both Motor #4 and Motor #3 as both identical motors will be replaced.

The proposed new motors will be designed to operate with the new VFDs being installed as part of Project LH1332 – Lake Huron Electrical System Upgrades. Since the removal of the old VFDs, these pumps have only been able to operate at a fixed speed, making the operation of the facility at different treatment rates difficult. Though not hard on the motors themselves, the use of fixed speeds creates challenges for plant operations as they have to constantly manually manipulate valve positions in order to match flows within the plant and the transmission system. This scenario also increases overall maintenance requirements to various motors, valves and pumps.

At the time of writing this report, OCWA has placed the order for Motor #4 and anticipates that it will arrive in approximately 16 weeks. The addition of the proposed motor to replace Motor #3 would not significantly change the delivery schedule.

The previously approved budget for LH1222 Low Lift Pump Rebuild Project is $150,000. Adding another motor for Low Lift Pump #3 would add an additional $120,000 to the project budget.

The overall estimated value of the work associated with low lift pump rebuild, including Motor #3, is approximately $300,000, noting that OCWA is responsible for paying the first $31,795.51 in accordance with the Service Agreement related to maintenance and repair of assets.

CONCLUSION

With the replacement of this motor along with the work being done on Low Lift Pump #4 and the replacement of the VFD, the plant will be able to return to a more efficient operating scenario, minimizing the risk of pump failure. It is the recommendation of staff to increase the budget for LH1222 to undertake the additional replacement of the motor for Pump #3.
