Report To: General Government Committee Date of Meeting: January 10, 2022 Report Number: CSD-002-22 Submitted By: Reviewed By: File Number: George Acorn, Director of Community Services Andrew C. Allison, CAO Resolution#: GG-012-22 By-law Number: Report Subject: Orono Arena and Newcastle Memorial Arena Renovations Recommendations: 1. That Report CSD-002-22 and any related communication items, be received; 2. That Council refer the proposed budget of $6,402,000 (exclusive of debt administration costs) to the 2022 budget for consideration; and 3. That all interested parties listed in Report CSD-002-22 and any delegations be advised of Council's decision. Municipality of Clarington Report CSD-002-22 Report Overview Page 2 In this report, staff are seeking Council consideration, by referring this report to the 2022 budget meeting, of necessary infrastructure renovations to the Orono Arena and Community Centre and Newcastle Memorial Arena. Both facilities are over 45 years old and have not undergone any major renovation/upgrade to date. In August 2020, an arena refrigeration engineering firm was retained to complete assessments of the arena floors, rink board systems, refrigeration plant equipment and de- humidification systems at both facilities. Based on the findings of these assessments, staff are recommending the replacement of the main components of the refrigeration system including the refrigerated arena floor, at both locations. Additionally, staff in consultation with the Boards, have identified further renovations and upgrades that should be considered at the same time. It is recommended that the investment be made in the refrigeration infrastructure at both arenas to replace major components and extend the useful life of both facilities by 10 — 15 years. Without the necessary upgrades, the refrigeration systems, specifically the refrigeration piping in the concrete arena floors are subject to unexpected failure that could result in the shutdown of the facility and the loss of months of the ice operation season. 1. Background 1.1 In a previous report on the future recreation facility for Bowmanville, Report CSD-003- 21, staff had identified the state of the aging infrastructure at the two Board operated arenas. Both facilities were opened in the mid-1970s and although they have been well maintained over the years, there has been no major replacement of the refrigeration infrastructure at either facility. 1.2 In 2010, the Municipality completed a $2.2M upgrade to the Darlington Sports Centre, which opened in 1975. The work included the replacement of the refrigerated arena floor, rink board system, refrigeration equipment as well as an interior lobby expansion and accessibility improvements. The objective of this upgrade was to extend the useful life of the facility by 15 years or to 2025, at a minimum. Based on the current condition of the building, staff are confident the facility will remain fully operational beyond 2025. It is intended that the proposed renovations in Orono and Newcastle will have the same positive impact on their useful life. 1.3 In August 2020, Community Services retained an independent arena engineering firm to provide an assessment of the ice rink and refrigeration systems for the Orono Arena and Community Centre (Attachment 1) and the Newcastle Memorial Arena (Attachment 2). The scope of their work included an assessment of the refrigeration plant equipment, Municipality of Clarington Report CSD-002-22 Page 3 the refrigerated arena floors/associated piping, the rink board/glass systems, and de- humidification systems. In September 2020 we received a report for each facility that was shared with each Arena Board Chair. 1.4 The major findings in both reports included the recommendation to replace the ammonia chillers in both arenas. As failure of this equipment could present a hazard to both staff and the public, this work was approved in our 2021 capital budget and was completed this past summer. The reports also concluded that, based on the age of both refrigerated arena floors, a failure of the imbedded brine piping system could occur at any time. It was recommended that replacement of both floors and the associated refrigeration systems be planned for in the near term. 1.5 To provide some context, both arena floors are original and have been in service for over 40 years. By comparison, the floor at Darlington Sports Centre was replaced after 35 years and Pad A at the Garnet Rickard Complex was replaced after 30 years. With a median useful life of 25 — 30 years for arena floors, both have far exceeded that benchmark. A major floor failure at the start of or during an ice season could result in a loss of that ice season, with significant impact to rental revenues and recreation services to the communities. 1.6 Based on the existing (pre COVID-19) demand in Clarington for ice time, it is critical to keep all existing ice surfaces fully operational as the loss of one ice surface would have a major impact on the ability to provide a satisfactory level of service to our community. In fact, the current ice supply is not able to fully satisfy the current needs of our minor sport organizations and as has been previously reported, they are required to seek additional ice time outside Clarington. 1.7 Currently there are a total of seven arenas operating in Clarington, with five being Municipally operated. While Council has also been considering the expansion of indoor recreation for Bowmanville, including a new twin pad arena, it is important to point out this is not for planned replacement for existing facilities. The two additional ice surfaces, when constructed, will assist in satisfying the demand for ice time across Clarington, that has occurred due to current and future residential growth. This demand includes a need for additional hours for public programming (public and parent/tot skating) and minor hockey, including for the Newcastle Village Minor Hockey Association. 1.8 According to the 2017 Indoor Recreation Facility Development Strategy, contingent on the existing demand for ice to be sustained, any decision on the fate of our older arena facilities would not be recommended, until such time as Council approves the construction of another twin pad arena at the Diane Hamre Recreation Complex. This will require the two Board operated arenas, as well as the Darlington Sports Centre, to effectively operate until the new ice pads planned for Diane Hamre are constructed and operational. Municipality of Clarington Page 4 Report CSD-002-22 2. Refrigeration System Assessments — Major Findings 2.1 These assessments were completed by I. B. Storey Inc. in August 2020. The purpose was to assess the current state of the facility in terms of ice rink operations and to make recommendations on immediate and short term required actions, suggestions on performance enhancements, and recommend a long-term capital plan to extend the useful life of the facility. 2.2 If this project is approved by Council, staff will undertake further investigation and non- destructive testing, after this ice season, on the various refrigeration components to prepare the specifications and final scope of the proposed upgrades. Newcastle Memorial Arena 2.3 As previously mentioned, the shell and tube ammonia chiller was identified as being at the end of the median life and was susceptible to failure. Due to the potential hazard this would pose, a new chiller was installed this past summer and would not be included in the proposed refrigeration equipment upgrade. 2.4 The two refrigeration compressors were showing signs of wear and tear on the exterior, with one unit being beyond 20 years of age and at the end of useful life. The other newer compressor is over 50% through useful life and will need replacement, based on the observed condition, in the next 4-5 years. If the project is approved, a more detailed assessment of this compressor will be done prior to being replaced. 2.5 At the time of the inspection, the arena floor was 44 years of age with evidence of surface wear and tear including previous areas of concrete patching. The exposed piping in the header trench showed signs of rust and decay. At this age, the floor is susceptible to failure and was recommended for replacement in the near term. 2.6 Based on the condition of the rink board system, it is assumed the structure is original with partial repairs and modifications being completed over time. Significant corrosion was noted on the metal framing at the entrance to the ice surface and there was evidence of splitting and cracking of the plywood at the ice surface level. A new board and glass system is being proposed. 2.7 The arena is equipped with two mounted de -humidifier units. At the time of the inspection the units were not in operation and were not accessible. Based on the style of the units, which were not produced after 2007, the units were at least 13 years old in 2020. It is recommended these two units be replaced at the time of the major renovation. 2.8 An assessment of compliance with the CSA B52 Mechanical Refrigeration Code was also completed. This is the Regulation, adopted by the Technical Standards and Safety Municipality of Clarington Report CSD-002-22 Page 5 Authority (TSSA), for the safe design, construction, maintenance, and operation of refrigeration systems in Ontario. Some items identified were dealt with this past summer and the remaining "grandfathered" compliance concerns will be included in the proposed project. 2.9 It was also observed the refrigeration system controls were out of date and, with their replacement, the refrigeration system will be able to operate more effectively and help improve ice quality at the same time as better managing energy consumption. Orono Arena and Community Centre 2.10 As was the case for Newcastle Arena, the shell and tube ammonia chiller was at or near the end of the median life and, based on the observation of exposed components was showing signs of significant rusting. This chiller was also replaced this past summer and will not be included in the proposed equipment replacement plan. 2.11 The two refrigeration compressors were showing signs of rust on the exterior and, based on the information available, are 20 years old and at the end of their median lifecycle. The proposed project includes replacement of both compressors. 2.12 At the time of the inspection the arena floor was 42 years of age with some evidence of minor surface wear. At this age, the floor is well beyond the median age and is susceptible to failure and was recommended for replacement in the near term. Based on the proposed construction schedule this would occur in 2024. 2.13 The rink board system was installed in 1978 and for the most part is original, although it is evident that sections have been replaced. Significant corrosion was noted on the metal framing at the bench doors and the entrance to the ice surface and there was evidence of splitting and cracking of the plywood at the ice surface level. A new board and glass system is being proposed. 2.14 The arena is equipped with two mounted de -humidifier units. At the time of the inspection the units were not in operation and were not accessible. Subsequent to the inspection, one unit was replaced this year and the other unit is good condition. It is recommended these units be integrated in the refrigeration controls upgrade. 2.15 An assessment of compliance with the CSA B52 Mechanical Refrigeration Code was also completed. This is the Regulation, adopted by the Technical Standards and Safety Authority (TSSA), for the safe design, construction, maintenance, and operation of refrigeration systems in Ontario. Some items identified were dealt with this past summer and the remaining "grandfathered" compliance concerns will be included in the proposed project. Municipality of Clarington Page 6 Report CSD-002-22 2.16 It was also observed the refrigeration system controls could be improved and with their replacement the refrigeration system will be able to operate more effectively and help improve ice quality at the same time as better managing energy consumption. 3. Financial Considerations 3.1 The Municipality has received indicative rates for serial debentures for ten years. These rates are subject to change up until the debenture is issued. Serial debentures provide equal principal payments with declining total debt costs over the term of the debt. Per discussion with the Region of Durham this is the structure they are currently utilizing for their debenture issues. 3.2 While the project would involve two arenas, it is recommended that they be debentured, and work completed simultaneously to reduce the cost of debt issuance. Newcastle Memorial Arena 3.3 Proposed Project Budget: Engineering & Design 307,000 Construction 3,070,000 Project Contingency 307,000 Total $3,684,000 Orono Arena and Community Centre 3.4 Proposed Project Budget: Engineering & Design 226,500 Construction 2,265,000 Project Contingency 226,500 Total $2,718,000 3.5 Staff have assumed a rate of 2.20 per cent for a 10-year debenture. The interest rate is the current indicative rate and is subject to change; a 10-year debenture is recommended as the useful life of the renovation is approximately 10-years. A debenture greater than 10-years would be against prudent fiscal planning and the current Debt Management Policy of the Municipality. 3.6 The total cost of debt, assuming $6.6 million in principal to cover costs, would be approximately $7,398,600. Interest costs would total approximately $798,600. As this is a renovation of existing infrastructure there would be no eligibility for development charges. Municipality of Clarington Report CSD-002-22 Page 7 3.7 The proposed debt, exclusive of debt required for a new facility, would not bring the Municipality near its internal debt limit. With the proposed debt of a new recreation facility, the debt servicing charge would approximate 7.5 per cent which is allowed within the Debt Management Policy of the Municipality. 3.8 Including proposed debt for a new facility, the annual debt servicing charges are illustrated below: $40,000,000 $30,000,000 $20,000,000 $10,000,000 C� Forecasted P&I payments vs ARL ■ Total P&I ❑ Annual Repayment Limit (ARL) N lzt l0 00 O N lzt l0 N N N N O O O O O O O O 4. Proposed Project Schedule 00 O N l0 00 O O O O O O O O N N N N N N N 4.1 Although the project budget is being requested in 2022, staff are recommending the engineering be completed this year with the renovation work being completed at Newcastle in 2023 and in Orono in 2024. 4.2 It is estimated the renovation work would take up to seven months to complete, which would require coordination with each Arena Board to shorten their existing spring schedule or to delay their fall re -opening. 4.3 Staff plan to coordinate the engineering and design work for both locations, and if possible, tender the work as one project, with two distinct construction schedules. If this can be accomplished, we may be able to attract a more competitive price for both locations. Municipality of Clarington Page 8 Report CSD-002-22 5. Concurrence 5.1 This report has been reviewed by the Director of Financial Services/Treasurer who concurs with the recommendations. 6. Conclusion 6.1 It is respectfully recommended that Council consider this project during the deliberation of the 2022 budget. Staff do realize this is a significant investment in two older indoor arenas, however, without a planned approach to the replacement of the two refrigerated arena floors, we risk the failure of these floors that would result in the facility being non- operational for a minimum of six months. The loss of a partial or entire ice season at either arena would have a drastic impact on the supply of ice for not only the local community but the entire municipality. 6.2 As the proposed upgrades are intended to extend the useful life of each facility by 15 years, or beyond, it is necessary to make the investment in the refrigeration system infrastructure at this time.

CONFIDENTIAL & PROPRIETARY PAGE 5 Rink Engineering Experts Version 1.0 MUNICIPALITY OF CLARINGTON — ORONO ARENA & COMMUNITY CENTRE Inspection Report — Rink Refrigeration & Pad Observations and Analysis • The chiller is very near the median end of life, and may be subject to failures in the near future. The chiller and attached surge drum are the primary ammonia storage vessels and given the hazardous nature of ammonia the chiller should not be allowed to operate near the median end of life. • Chiller failures are a serious risk to public health and safety because toxic refrigerant may leak. Replacement of the chiller should be considered as soon as possible'. • Inspection of the chiller is due in January 2021 for insurance 14 hgl_�10 Rink Engineering Experts Figure 2: Signs of rusting on the chiller. purposes. • Chiller relief valves need to be replaced by June, 2023. This is a critical safety component. • While the chiller and surge drum are covered in an insulating layer that limits direct inspection, exposed elements where piping connects shows significant signs of rusting. This suggests the potential for corrosion throughout the vessel. Recommended Actions .•. Immediate • Have a brine analysis performed to check for ammonia contamination in brine as an Actions early sign of chiller failure to mitigate danger to operators and users. Short -Term • Have chiller and surge drum re -inspected by January 2021 for insurance purposes. Actions • Replace chiller relief valves by June 2023 as required. • Perform ongoing monitoring of brine to test for potential chiller failure. Additional ongoing monitoring is recommended, including2: o Check for any increase in volume in the secondary refrigerant (brine) system. o Check for any unusual increase in pressure in the secondary refrigerant (brine) system. o Test the system heat exchange for leaks during the off season. Capital • Pursue opportunities to replace the chiller as soon as possible. Expenditure o This is a significant health and safety risk. Replacing the chiller on its own Planning or as part of a total refrigeration plant upgrade should be prioritized. Given the age of all of the equipment, a full plant replacement is recommended at this time. ' Based on the current condition of the refrigeration plant equipment, a full plant replacement is recommended. 2 Refer to Technical Safety BC SO-BP-2017-01 "Safety Order: Ammonia refrigeration systems in public occupancies" for detailed recommendations prepared by Technical Safety BC following the tragic and fatal ammonia release accident in Fernie, British Columbia in 2017. 1.B.

As these standards are updated regularly, even facilities which were once in compliance may find that their systems have either been grandfathered into "compliance" or age has rendered some, or all, components non -compliant. The following are two lists of non -compliant TSSA issues found during the review of the refrigeration room at the Orono Arena. The first list contains critical items which need to be addressed at the next available opportunity to ensure safety of the community centre users in the case of an emergency and the second list contains other items which need to be taken care of to ensure complete compliance with code. To aid in understanding these deficiencies, clauses associated with deficiencies have been laid out with associated photos and a complete check list of the B52-standard attached as appendices.

Ensuring that the mechanical room meets TSSA safety standards is the first step that should fit into an overall plan to mitigate risks associated with providing efficient refrigeration for the facility. Facility Users and Community ■ Further Risk Mitigation B52-18 Compliance Refrigeration Roam At a minimum, the following should be considered when determining the safety requirements that should be adopted for a refrigeration system: • Safety to operators of the refrigeration system. • Safety to users of the facility. • Safety to public infrastructure (malls, schools, roads, etc.) around the facility. • Safety to private infrastructure (homes, condos etc.) around the facility. • Safety to the natural environment around the facility. Since the initial installation of the refrigeration system in the 1970s and the refurbishment in 2001, advancements in technology have continued to provide risk mitigating options for ammonia plant installations that would not have been available or feasible in the past. 1.B. Storey Inc. CONFIDENTIAL & PROPRIETARY PAGE 24 Rink Engineering Experts Version 1.0 MUNICIPALITY OF CLARINGTON — ORONO ARENA & COMMUNITY CENTRE Inspection Report — Rink Refrigeration & Pad Os Rink Engineering Experts The review at the Orono Arena has revealed that risk mitigation strategies can be implemented for several aspects of the system as follows, with each measure identified as focusing on health or finance concerns. Risk items are presented in a stacked order, with each risk being prevented by the successful mitigation of all risk items that follow. Risk Mitigated Ammonia Discharge Ammonia Relief Mechanical Failure Remote Monitoring and Brine Leak Monitoring Risk Item Notes/Actions Type • The refrigeration system at the Orono Arena does not have its refrigerant charge posted in the mechanical room as per B52 requirements (see Section 1), but based on the equipment in the plant the approximate refrigerant charge is 600 pounds. • In some cases, ammonia forms denser than air mixtures that roll along the ground, posing a danger to life, environment, and property. • Accidental full discharge is unlikely; however, reduction in charge greatly Ammonia Discharge reduces risk range in a worst -case scenario. Due to • Less charge reduces dispersal speed, providing emergency services with more Component failure time to respond. • A low charge plant will require approximately 60% less charge than existing system. • An ultra -low charge plant will require approximately 80% less than existing system. • Switching to an alternate, low -toxicity, environmentally sustainable refrigerant will prevent any hazards to nearby buildings and people. 1.B.

Pressure • Adding an indoor relief system as a first relief stage renders discharged ammonia harmless and keeps it from the atmosphere. • Both component failure and over pressure can result from the use of aging equipment. • Preventing component failure mitigates accidental ammonia discharge. • Aged equipment at the Orono Arena includes the chiller, pumps and Mechanical Failure compressors. At around 20 years old this equipment is nearing the end of its Due to useful life and is recommended for replacement in the coming years. Mechanical Age • Only one brine pump is available at the arena. In the event of failure, there is no emergency backup for continued ice operation. • Efficient mechanical design increases equipment life and reduces available failure points. • Information monitoring provides an operator with a first line of risk mitigation in any system. ORemote Information • Remotely provides information which alerts to operation of the system outside Monitoring of a preset tolerance. • Knowledge of such operation helps diagnose failing components or dangerous conditions long before they would become obvious. • The disposal of brine, which is used as a secondary refrigerant at the facility, is regulated and needs to be carried out properly. Q• To prevent, or at least, mitigate brine leaks, a brine leak monitoring system Brine Leak Monitoring should be installed on site. • Additional monitoring should be considered to detect ammonia leaks in the brine, to provide additional safety.

These ranges are presented for visualization and decision -making purposes only. • The existing refrigeration plant range, shown in red, covers nearly 50 residential properties, Orono United Church, Orono Agricultural Society, fair grounds, and an antique market. • Low charge plant (60% reduction), shown above in purple, would result in roughly 30 properties being removed from the immediately dangerous to life and health range but would still impact the fair grounds and private residences. • Ultra -low charge plant (80% reduction), shown in blue, would limit dispersal to the arena, its parking lot, part of the fair grounds and a handful of nearby residential properties. • Switching to an alternate, lower toxicity, environmentally sustainable Al category refrigerant could remove the impact to surrounding buildings entirely and eliminate issues with toxicity and flammability. • Reduction in the IDLH range provides more time for people to evacuate and emergency teams to arrive, as the charge disperses slower. These ranges must be considered even if on -site ammonia evacuation equipment is used, as the refrigerant is still on site. 1.B. Storey Inc. CONFIDENTIAL & PROPRIETARY PAGE 27 Rink Engineering Experts Version 1.0 MUNICIPALITY OF CLARINGTON — ORONO ARENA & COMMUNITY CENTRE Inspection Report — Rink Refrigeration & Pad CORRECTIVE ACTIONS Os Rink Engineering Experts The following recommendations have been categorised into compulsory actions required to meet the CSA B52 standards and risk mitigation considerations for implementation as budget allows. 1. Safety Compliance • Tight fitting of pipe and conduit through machine room walls. • Installation of proper system labelling including key details about refrigerant charge and emergency contacts. • Installation of railing or fall protection measures for the evaporative condenser. • Install on -only switch for the ventilation fan outside the mechanical room. • Install a new exhaust ventilation system that only serves the refrigeration room. Budget Cost: $12,000 2. Risk Mitigation • As the age of the refrigeration plant is closing on 20 years, it is advised that new refrigeration plant equipment be investigated in the near future. o Based on the close proximity to nearby residential and community properties, it is recommended that a low -toxicity refrigerant be pursued. o Converting to a low -toxicity environmentally sustainable refrigerant will not result in operating cost increase. • Install indoor ammonia containment for the relief system if ammonia is kept on site. • Install, or have on standby, an extra brine pump in case of unexpected failure of the main pump. • Install, or have on standby, an extra water pump in case of unexpected failure of the main pump. • Install a remote monitoring system for the refrigeration plant. • Install brine leak detection system. Budget Cost: $750,00011 In This budget cost is suitable for either the low charge (60% refrigerant reduction) or low -toxicity refrigerant options. Additional costs required for the ultra -low charge (80% refrigerant reduction) option. 1.B. Storey Inc. CONFIDENTIAL & PROPRIETARY PAGE 28 Rink Engineering Experts Version 1.0 MUNICIPALITY OF CLARINGTON — ORONO ARENA & COMMUNITY CENTRE Inspection Report — Rink Refrigeration & Pad CONCLUSIONS AND NEXT STEPS Os Rink Engineering Experts In order to ensure efficient and safe operation of the plant, it is recommended that the renewal of the refrigeration plant be pursued at the earliest convenience as the most recent TSSA assessment in the room was from May 2012, 8 years ago. Corrective actions not directly related to the installation of a new refrigeration plant should be corrected at the same time. Next steps are outlined as follows: • Review report to select measures to be implemented. • Engineering design of selected measures. • Obtain actionable budget. • Project facilitation to ensure compliant installation. Based on the aging life of the refrigeration equipment, it is recommended that a complete renewal of the rink refrigeration system be planned for within 1 to 5 years. The ongoing status of the chiller should be closely monitored to ensure public health and safety with regular brine tests to detect ammonia leaks and potential chiller failure. 1.B. Storey Inc.

The CSA B52 Mechanical Refrigeration Code is the standard adopted by the TSSA for refrigeration regulation in Ontario and is intended to minimize the risk of personal injury by providing minimum requirements for the design, construction, installation, inspection, and maintenance of mechanical refrigeration systems. As these standards are updated regularly, even facilities which were once in compliance may find that their systems have either been grandfathered into "compliance" or age has rendered some, or all, components non -compliant. The following are two lists of non -compliant TSSA issues found during the review of the refrigeration room at the Newcastle Memorial Arena. The first list contains critical items which need to be addressed at the next available opportunity to ensure safety of the community centre users in the case of an emergency and the second list contains other items which need to be taken care of to ensure complete compliance with code.

O s -30 Rink Engineering Experts While the review of the ammonia plant has revealed several items that are non -compliant with the TSSA refrigeration standards, it is paramount to note that the TSSA standards are only a bare minimum. Ensuring that the mechanical room meets TSSA safety standards is the first step that should fit into an overall plan to mitigate risks associated with providing efficient refrigeration for the facility. Facility Users and Community ■ Further Risk Mitigation B52-18 Compliance Refrigeration Room At a minimum, the following should be considered when determining the safety requirements that should be adopted for a refrigeration system: • Safety to operators of the refrigeration system. • Safety to users of the facility. • Safety to public infrastructure (malls, schools, roads, etc.) around the facility. • Safety to private infrastructure (homes, condos etc.) around the facility. • Safety to the natural environment around the facility. Since the initial installation of the refrigeration system in the 1970s and the refurbishment in 1999 (with an additional compressor replacement in 2010), advancements in technology have continued to provide risk mitigating options for ammonia plant installations that would not have been available or feasible in the past. 1.B. Storey Inc. CONFIDENTIAL & PROPRIETARY PAGE 24 Rink Engineering Experts Version 1.0 MUNICIPALITY OF CLARINGTON — NEWCASTLE MEMORIAL ARENA Inspection Report — Rink Refrigeration & Pad Os Rink Engineering Experts The review at the Newcastle Memorial Arena has revealed that risk mitigation strategies can be implemented for several aspects of the system as follows, with each measure identified as focusing on health or finance concerns. Risk items are presented in a stacked order, with each risk being prevented by the successful mitigation of all risk items that follow. Risk Mitigated Ammonia Discharge Ammonia Relief Mechanical Failure Remote Monitoring and Brine Leak Monitoring Risk Mitigation Risk Item Notes/Actions Type • The refrigeration system at the Newcastle Memorial Arena does not have its refrigerant charge posted in the mechanical room as per B52 requirements (see Section 1), but based on the equipment in the plant the approximate refrigerant charge is 600 pounds. • In some cases, ammonia forms denser than air mixtures that roll along the ground, posing a danger to life, environment, and property. • Accidental full discharge is unlikely; however, reduction in charge greatly Ammonia Discharge reduces risk range in a worst -case scenario. Due to • Less charge reduces dispersal speed, providing emergency services with Component failure more time to respond. • A low charge plant will require approximately 60% less charge than existing system. • An ultra -low charge plant will require approximately 80% less than existing system. • Switching to an alternate, low -toxicity, environmentally sustainable refrigerant will prevent any hazards to nearby buildings and people. 1.B.

These ranges are presented for visualization and decision -making purposes only. • The existing refrigeration plant range, shown in red above, covers more than 50 residential properties. • Low charge plant (60% reduction), shown in purple above, would result in approximately 35 properties being removed from the immediately dangerous to life and health range. • Ultra -low charge plant (80% reduction), shown in blue above, would limit dispersal to the arena and the nearest 6 residential properties. • Switching to an alternate, lower toxicity, environmentally sustainable Al category refrigerant could remove the impact to surrounding buildings entirely and eliminate issues with toxicity and flammability. • Reduction in the IDLH range provides more time for people to evacuate and emergency teams to arrive, as the charge disperses slower. These ranges must be considered even if on -site ammonia evacuation equipment is used, as the refrigerant is still on site. 1.B. Storey Inc. CONFIDENTIAL & PROPRIETARY PAGE 27 Rink Engineering Experts Version 1.0 MUNICIPALITY OF CLARINGTON — NEWCASTLE MEMORIAL ARENA Inspection Report — Rink Refrigeration & Pad CORRECTIVE ACTIONS 1. O s -30 Rink Engineering Experts The following recommendations have been categorised into compulsory actions required to meet the CSA B52 standards and risk mitigation considerations for implementation as budget allows. 1. Safety Compliance • Tight fighting of emergency outdoor exit and window from mechanical room. • Tight fitting of pipe entrance through ceiling, and tight -fitting brine pipe entrance into the brine trench. • Installation of 1-hour fire -resistive tight -fitting trench cover for the brine trench. • Relocation of the emergency relief box to be at the required height. • Adjustment of refrigerant piping in the mechanical room to provide the required 7-1/2 ft free clearance. • Installation of proper system labelling including key details about refrigerant charge and emergency contacts. • Installation of railing or fall protection measures for the evaporative condenser. • Install new ammonia gas detector or properly calibrate the existing unit. Budget Cost: $50,000 2. Risk Mitigation • As the age of the refrigeration plant is closing on 20 years, it is advised that new refrigeration plant equipment be investigated in the near future. o Based on the close proximity to nearby residential and community properties, it is recommended that a low -toxicity refrigerant be pursued. o Converting to a low -toxicity environmentally sustainable refrigerant will not result in operating cost increase. • Install indoor ammonia containment for the relief system if ammonia is kept on site. • Install, or have on standby, an extra brine pump in case of unexpected failure of the main pump. • Install, or have on standby, an extra water pump in case of unexpected failure of the main pump. • Install a remote monitoring system for the refrigeration plant. • Install brine leak detection system. Budget Cost: $750,000" is This budget cost is suitable for either the low charge (60% refrigerant reduction) or low -toxicity refrigerant options. Additional costs required for the ultra -low charge (80% refrigerant reduction) option. I.B. Storey Inc. CONFIDENTIAL & PROPRIETARY PAGE 28 Rink Engineering Experts Version 1.0 MUNICIPALITY OF CLARINGTON — NEWCASTLE MEMORIAL ARENA Inspection Report — Rink Refrigeration & Pad CONCLUSIONS AND NEXT STEPS 1. O s -30 Rink Engineering Experts In order to ensure efficient and safe operation of the plant, it is recommended that the renewal of the refrigeration plant be pursued at the earliest convenience as the most recent TSSA assessment in the room was from December 2008, 12 years ago. Corrective actions not directly related to the installation of a new refrigeration plant should be corrected at the same time. Next steps are outlined as follows: • Review report to select measures to be implemented. • Engineering design of selected measures. • Obtain actionable budget. • Project facilitation to ensure compliant installation. Based on the aging life of the refrigeration equipment, it is recommended that a complete renewal of the rink refrigeration system be planned as soon as possible. The ongoing status of the chiller should be closely monitored to ensure public health and safety with regular brine tests to detect ammonia leaks and potential chiller failure. The current state of the refrigeration system and rink floor will require a significant investment for continued operation. It should be noted that a major building overhaul replacing the rink floor and refrigeration plant can be accomplished for approximately 50 to 60% of the cost of full new construction. Though it is outside of the scope of this study, several key building upgrades are recommended to be pursued as part of the overhaul. The existing mechanical room shows severe signs of wear and is well below code. This is an additional block structure that was built onto the end of the rink, and it is recommended that as part of the upgrades the entire room be demolished and replaced. This would address the code issues as well as the cracked and sloping floors observed in the refrigeration room. The building currently has 4 dressing rooms, while 6 dressing rooms is the current standard.
