1.1 Overview

Through 2016, EPCOR Water Services Inc. (EWSI) continued to satisfy all water demand requirements while meeting our strict water quality criteria. Despite growth of the service population, total demand in 2016 fell as compared to 2015 due to the cooler, wetter summer conditions. Residential per capita and total per capita values also continued to trend downward primarily due to the installation of water efficient fixtures and appliances. Rossdale WTP and E.L. Smith WTP were converted from Direct Filtration (DF) to conventional treatment on February 29th and March 3rd respectively to prepare for the spring runoff. It arrived earlier than previous years but was short-lived and very mild. The spring runoff did not bring any taste and odour concerns and required far less chemicals to treat, as compared to previous years. Mountain runoff, which normally hits the North Saskatchewan River (NSR) in Edmonton in June and usually brings high turbidity, was also very mild. The heavy rainfalls in July did increase the river raw water turbidity to ~1700 NTU and colour to ~40 TCU but the water plants were able to treat the river water quality easily. Near the end of August, significant storm events upstream of Edmonton caused the NSR level to rise almost 4 meters in less than a day, bringing high turbidity ~3000 NTU and unusually high colour of greater than 200 TCU. This high river level event caused a considerable amount of damage within one of the pumphouses at E.L. Smith WTP. Both water treatment plants struggled to produce water during this event and demand management measures were implemented for four days due to low reservoir levels.

Edmonton WTPs continued to focus on optimizing chemical dosing and minimizing release of water treatment plant solid residuals to the NSR. Several process initiatives were investigated to improve plant performance during DF and solids reduction: • Higher dosages of filter polymer of up to 2 mg/L were tested in the plants during DF operation. Zeta potential and filter performance were monitored during this time in an attempt to optimize filter polymer dose.

• A plant trial was carried out at E.L. Smith for the second consecutive year during which sulphuric acid was injected into one of the raw water lines to reduce clarifier influent pH. The objective of the trial was to determine if pH reduction through the clarifiers would improve filter performance during the early fall period when raw water pH is relatively high.

• A pilot plant trial was conducted for an alternate filter polymer (LT-7995) in an effort to improve filter run times and filter effluent quality during direct filtration.

Conversion from conventional treatment to DF was delayed for both plants due to the unusually high colour in the NSR that arrived with the high river level in late August and lasted until the end of 2016. Rossdale WTP converted to DF on December 19th. E.L. Smith WTP converted Clarifier 3 and Stage 1 filters to DF on November 28th to accommodate the pH adjustment trial, but was converted back to conventional treatment on December 3rd due to river water quality. The full E.L. Smith WTP was converted to DF on December 28th, but was converted back to conventional treatment on December 30th due to low water production and high process losses in DF mode. E.L. Smith WTP successfully converted to DF on January 6, 2017. Despite the challenges, the WTPs were still able to reduce total solids discharged to the NSR by 41% during the months of January – February 2016 compared to baseline conventional operation. In-stream sampling and monitoring of WTPs clarifier waste stream discharges to NSR continued in 2016 to further understand the impacts of residuals discharge on the river environment.

There were a total of four AEP approval contraventions at the WTPs in 2016, as detailed in Section 1.4 Summary of Violations and Notifications. WTPs continue to improve the integrated safety and environmental management system in accordance with the ISO14001:2004 and OHSAS 18001:2007 standards. Surveillance audits were conducted in late November 2016 for Rossdale and E.L. Smith WTPs, along with the reservoir sites.

EWSI continued to upgrade the water treatment plants and the reservoir assets. Thirty-four capital projects under different programs were initiated in 2016 with a total spending of approximately $13.1M. Some of the major projects are as follows:

• Rossdale Polymer System Upgrade – construction was commissioned and completed by Q2 2016; • Rossdale Chem spill upgrade – construction in progress, plan to be commissioned and completed by Q2 of 2017; • ROS - Filter Underdrain Upgrades (Filter# 9) – construction in progress, plan to be commissioned and completed by Q2 of 2017; • ROS - Guardhouse and Fence – construction in progress, plan to be commissioned and completed by Q3 of 2017; • ELS Lowlift PH Intake Upgrade/ Travelling water screens upgrade – construction was commissioned and completed by Q4 2016; • Construction completed for the two new booster stations – Big Lake in the NW and Walker in the SE. Both sites are commissioned and working on addressing all deficiencies.

In 2016, Water Distribution and Transmission repaired 242 water main breaks on the distribution system in Edmonton, with the majority of main breaks occurring on cast iron pipes. While this number is the lowest number of main breaks experienced since 1961, the trend of a higher proportion of breaks occurring on larger diameter mains continued. The general trend of decrease in water main break activity continued and this improvement in overall reliability of the water distribution system can be attributed to the water main replacement programs as well as the use of more reliable pipe materials in both replacement and new water main construction.

In 2016, the Uni-Directional Flushing program completed flushing and valve exercising in about 33% of Edmonton (2,112 runs).This program is a five-year cycle with area prioritization emphasis placed on water quality parameters, percentage of Cast Iron Mains, and the relative success of the previous flush. The transmission valve inspection program is ongoing. Water Distribution and Transmission Customer Satisfaction index year-end results were 77.8% and finished above the 74% target.

EWSI continues to provide water and wastewater services and expertise to numerous communities in Alberta, British Columbia, Regina, as well as industrial sites in Fort McMurray.

As we move into 2017, we will continue to focus our efforts on the production of and distribution of high quality water, customer satisfaction, protection of the environment, workplace safety and cost effectiveness. We will continue to ensure our customers receive best value for the services we provide them. More detail on our progress towards meeting our EnviroVista Stewardship community will be included in our annual EnviroVista report, which will uploaded to epcor.com by June 30th, 2017.

EPCOR AESRD Date of Incident Description Report File Incident Number Number A water sample collected on January 22, 2016 from the E.L. Smith reservoir tested positive for E. coli. Resamples from the same reservoir and from distribution samples on January 23 were all negative for Total Coliforms and E. coli. Identification of bacteria PH-00448 in the E. coli positive sample suggest that it was a raw water sample, that is, the 22-JAN-16 307574 employee erroneously filled the Res Out sample bottle with raw water. It was determined that a sampling error occurred where the sample was erroneously taken from the raw water tap and labeled as a treated water sample from the reservoir. A sample as part of the random distribution monitoring program tested positive for total coliforms. Following AEP’s Protocol for Failed Bacteriological Results, we attempted to collect a set of four resamples - upstream, downstream and two at the original site. The collection of the first set of resamples happened on Sunday and we were not able to access the business location as it was closed. On this day only three samples were PH-00483 collected (upstream, downstream, and at the nearby fire hydrant). All had chlorine and 13-MAY-16 311408 turbidity within normal operating ranges and all bacteriological results were negative for total coliform and E. coli. The following day (Monday), two more samples were collected from the business itself, one at the original sampling point, and one at an alternate point. Both samples had chlorine and turbidity within normal operating ranges and all bacteriological results were negative for total coliform and E. coli. Approximately 6 m of lead service pipe line was replaced at a customer’s residence, Following procedures on commissioning; samples were collected and submitted to the Lab for microbiological testing. The crew was unable to collect samples at the residence because the owner was away and collected the sample from a hose-bib. The sample PH-00496 tested positive for total coliforms but had normal levels of chlorine and turbidity. 26-MAY-6 311956 Following AEP’s Protocol for Failed Bacteriological Results, four samples were collected – upstream, downstream and two at the original location. All had chlorine and turbidity within normal operating ranges and all bacteriological results were negative for total coliform and E. coli. 1.4 Summary of Violations and Notifications for 2016

EPCOR AESRD Date of Incident Description Report File Incident Number Number As per AEP Approval 638-03-00, Schedule 3, E.L. Smith WTP is to provide continuous monitoring on filter turbidity. On June 1st, 2016, filter 18 NTU meter was flushed and after the flush the meter went to 0.01 NTU and stayed there until the filter was shut off on June 2nd @ 03:40 am. At 15:45 Filter 18 was brought back "On-line", but the NTU meter remained @ 0.01 NTU even though the filter particle counter did spike as per normal during "Filter to Waste". No check turbidity meter alarm came up on SCADA. PH-00497 The filter remained on-line and on June 4th @ 00:54, an Operator checked the meter 01-JUN-16 311408 and the meter then started to respond again. Hourly filter effluent turbidity grab samples were not taken during the period the analyzer was not responding as per Operations Program and Approval requirements. The maximum filter effluent average Particle count during this period did not exceed 12 c/ml. The maximum reservoir influent NTU was 0.04 during this period. Production from filter 18 on the first occurrence was 8 ML. On the second occurrence it was 30 ML. This incident was reported to AEP on June 9, 2016 at approximately 10:30 am. AEP Reference #: 312487 As per AEP Approval 638-03-00, Schedule 3 and the 2016 Edmonton Waterworks Operations Program, Section 2.3.5, E.L. Smith WTP is to provide continuous monitoring of Log Removal Credit. On June 8, 2016, at 14:50 the Log Removal program on the primary ELS SCADA system stopped working. There was no alarm. 19:03. Operations noticed log removal program not working and put plant to PH-00499 bypass to reset the Log Removal program. The program was reset at 19:36. 19:53 08-JUN-16 311956 plant back online and Log Removal program was working again. All of the analyzers and meters supplying data to the Log Removal program were functioning during this time. This data was used to manually calculate the Log Removal credit in 15 minute intervals that the Log Removal program was not functioning and the plant was online. The minimum Log Removal credits calculated during this time were above minimum approval requirements: Crypto = 7.0, Giardia = 7.4, Virus = 21.3. An existing hydrant, control valve and lead were replaced in the area of 80th street and 120th avenue Edmonton. Prior to recommissioning a water sample was collected from the hydrant that resulted in PH-00507 total coliform positive. Following AEP’s Protocol for Failed Bacteriological Results, 16-JUL-16 313915 resamples - upstream, downstream and at the original site were collected. All resamples were negative for total coliforms and E. coli. All samples had chlorine residual and turbidity within normal range. 1.4 Summary of Violations and Notifications for 2016

EPCOR AESRD Date of Incident Description Report File Incident Number Number Drinking water did not meet the minimum requirement for percent Ultraviolet transmittance (UVT) for the UV disinfection system at the E.L. Smith water treatment plant, and was pumped into the finished water reservoir and distribution system for several hours. To prevent depletion of reservoir storage to critical levels by the morning of August 25, the E. L. Smith production was diverted to finished water reservoirs and PH-00522 25-AUG-16 315485 distribution system with the percent UVT at approximately 87%. Minimum requirement is 88%. At the time of the incident, the quality of the raw water supply in the North Saskatchewan River had deteriorated significantly due to an intensive rainstorm event upstream in the watershed in the days prior to the incident. Water distribution sample taken at convenience store as part of routine distribution sampling program tested positive for Total Coliforms. Chlorine and turbidity levels were normal. Four resamples were collected as per the AEP Protocol for Failed Bacteriological PH-00524 23-AUG-16 315417 Results. Chlorine and turbidity were all within normal operating ranges. Total Coliform and E. coli were negative. It was suspected that the normal disinfection procedure that was followed was not sufficient to remove levels of contamination that the utility tap might have had. After a lead service renewal a sample was taken from a kitchen tap. The aerator could not be removed without a tool, so a sample was taken with it on. This resulted in a Total Coliform Positive. Resamples were collected as per the AEP Protocol for Failed PH-00520 Bacteriological Results. Chlorine and turbidity were all within normal operating ranges. 17-AUG-16 315177 Total Coliform and E. coli were negative for the resample. During the re-sampling event, the aerator was removed, and debris was cleaned from the kitchen tap. The resample at this location was negative for Total Coliform. A renewal project found a necessary valve to be inoperable. After the valve was replaced the line was flushed. A water sample at the nearby hydrant resulted in a Total Coliform Positive as per the AEP Protocol for Failed Bacteriological Results, resamples PH-00517 were taken at the original source and two locations upstream. However, with the 12-AUG-16 314982 renewal project still underway, a downstream location was not possible. Chlorine and turbidity were all within normal operating ranges. Total Coliform and E. coli were negative for the resamples. 1.4 Summary of Violations and Notifications for 2016

EPCOR AESRD Date of Incident Description Report File Incident Number Number Positive coliform indication occurred after a water sample was performed on newly installed hydrant barrel (H9029). As per the Failed Bacteriological Result protocol, a crew flushed H9029 and took a PH-00514 resample at the hydrant as well as upstream and downstream resamples from 03-AUG-16 314696 neighbouring hydrants. All resamples were negative for Total Coliforms, and E. coli. and had chlorine residual and turbidity within normal range. On August 16, 1:30 pm, as per routine operational practice every quarter, a sample was taken from the clarifier blowdown at the E.L. Smith Water Treatment Plant for testing. Every quarter, a sample is collected of clarifier blowdown (which is river solids coagulated with alum) and tested by an external laboratory. This practice goes beyond approval requirements. This event was reported as a notification only to Alberta Environment and Parks on September 15th, 2016. During mid-August, very heavy rains in the upstream NSR basin resulted in the NSR having very high flows (peaked at 1,400 cms) and also extremely high suspended solids ENV-01301 01-SEP-16 316176 concentrations and turbidity levels. In operating the E.L. Smith plant to produce potable water it was necessary to use relatively high alum doses to ensure public health protection and the clarifier blowdown was measured to have TSS concentrations. This waste stream is discharged to the river using an in-stream, mid-channel diffuser which uses in-stream mixing for rapid dilution to avoid in-stream adverse effects on biota. The sample collected did exhibit in the laboratory rainbow trout some affects at undiluted strength. At dilutions that the diffuser would achieve in the river no fish populations would have been expected to be affected. On Thursday September 1, 2016 a main renewal-tie in for was completed and sampled. Main was put back into service after disinfection, flushing, and water quality sampling. PH-00528 On September 3rd the construction coordinator was notified that the samples had 03-SEP-16 315813 tested positive for Total Coliform. Following AEP protocol, a flush was conducted and resamples obtained. All resamples results were negative for Total Coliform. 1.4 Summary of Violations and Notifications for 2016

EPCOR AESRD Date of Incident Description Report File Incident Number Number A city of Edmonton crew repairing a sanitary service line for an apartment hit a water service line. EPCOR was contacted and closed the water service, then hooked up temporary water service during repairs. The EPCOR crew used the same temporary adapter in the repair trench to obtain a water sample which tested positive for Total Coliforms and E. Coli, likely from contamination on the outside of the adapter. Chlorine PH-00531 10-SEP-16 316031 was within normal range. Resamples collected from two locations at the original address and from upstream and downstream were all negative for Total Coliforms, E. Coli and had normal Chlorine residual and turbidity. The distribution system would have been at very low risk for contamination as the water service line had continuous flow and pressure. Following a complaint of poor quality water EPCOR found low chlorine residual and high turbidity. Total Coliform and E. Coli were negative. Approval to Operate requires 75% of resamples within a 24 hour period be equal to or greater than 0.5 mg/L for chlorine. EPCOR crews were not able to obtain the required 4 samples in the area within 24 hours. PH-00538 22-SEP-16 316541 The area is a single feed main with only 4 single family residences beyond the last hydrant. The area has low water demand causing the original low chlorine. EPCOR was not able to gain access to all the residences within the 24 hours to complete the required sampling. Resamples were collected after 24 hours, these were negative for Total Coliforms, E. Coli and had chlorine and turbidity within normal ranges. EPCOR Crew fixed a hydrant leak. After finishing repairs a water sample was collected on October 3rd. However, we did not process the sample until October 7th. The stale sample resulted in a Total Coliform positive, but chlorine and turbidity were within normal ranges. PH-00542 08-OCT-16 317059 Following AEP protocol, the location was flushed, and 4 new samples were collected from the same source on October 8th. Final results were received October 11th, all samples negative for Total Coliform and E. coli. They were all within normal ranges for chlorine and turbidity. 1.4 Summary of Violations and Notifications for 2016

EPCOR AESRD Date of Incident Description Report File Incident Number Number Customer complaint of Taste and Odor on October 1st from a residence that had been vacant for several months. We initially advised them to flush all taps in the residence. Customer called back on October 7th with a similar concern. A sample on October 7th was collected at in the kitchen from a pull-out spray head, as this was the location of the continued water quality concern. The spray head was not properly disinfected prior to sampling and resulted in a Total Coliform positive. Four PH-00543 resamples, including one at the same spray were obtained. The spray head was Total 10-OCT-16 317060 Coliform positive a second time. All samples were normal for chlorine and turbidity in both sets. A second EPCOR crew was dispatched to the location. This time the spray head was disassembled and properly disinfected. Five resamples were obtained this time; all were negative for Total Coliform and E. Coli. They were also within normal range for chlorine and turbidity. A weekly analysis for chlorate at the Edmonton water treatment plants from a sample collected December 27th was above the maximum allowable concentration of 1 mg/L as per the Guidelines for Canadian Drinking Water Quality. Re-samples were taken December 27, 28, and 30 from the distribution system and from both water plants. A PH-00559 30-DEC-16 319584 second set of re-samples were also sent to a third party lab for analyses. It was determined that our internal lab results were in error and that chlorate levels were 0.1 mg/L. The cause of the internal lab error was instrumentation that was not fully conditioned after undergoing scheduled maintenance.
