1.1.1 Operations – Rossdale and E.L. Smith Plants

Plant Bypasses

The number of bypasses shown on Table 1.2.26 “Rossdale Waste Stream Data” and Table 1.2.27 “E.L. Smith Waste Stream Data” include both planned and unplanned bypasses. A planned bypass is any bypass that is planned a minimum of one day ahead of the actual bypass. All other bypasses are considered unplanned. In July, Rossdale Plant had one planned bypass and no shutdowns. Date Type Bypass Description 17 minute planned plant bypass due to ammonia feed line July 19 Planned switch.

In July, E.L. Smith Plant had two unplanned bypasses and no shutdowns. Date Type Bypass Description July 6 Unplanned 40 minute bypass due to power lost to feeder EP-101 July 6 Unplanned 40 minute bypass due to power restored to feeder EP-101

Clarifier Blowdown Volume

♦ The clarifier blowdown volume shown on Table 1.2.26 and Table 1.2.27 include estimated plant leakage.

Dechlorination Highlights

♦ During the month of July, there were zero instances of chlorinated waste released at the outfall structure at Rossdale Water Treatment Plant. ♦ During the month of July, there were zero instances of chlorinated waste released at the outfall structure at E.L. Smith Water Treatment Plant.

Chemical Dosing Highlights

In July, Rossdale and E.L. Smith Water Treatment Plants did not exceed the Maximum Use in the Standard 60, published by the National Sanitation Foundation and the American National Sanitation Standards Institute (NSF/ANSI) for Alum or Caustic Soda.

1.1.2 EDMONTON INCIDENT REPORT SUMMARY – July 2021

EPCOR AEP Incident Description Date of Incident Reference Number Number As part of recent routine flushing activities near and Connaught Drive, water distribution samples were collected (H1666 and H27088) and brought to the Rossdale Laboratory for regular turnaround testing. Laboratory results indicated detections of BTEX compounds in both pre- and post-flush samples, including MAC exceedances for benzene, resulting in a potential AEP reportable incident within Edmonton’s water distribution system. Health ’s Maximum Acceptable Concentration (MAC) for benzene is 5 µg/L and sample results were up to 7.16 µg/L. ENV- Given a MAC was exceeded in the sample, the AEP Action Protocol for Exceedances of Chemical Health Parameters in Drinking Water was 20210726- July 26, 2021 381700 036969 followed and the finding was called into AEP’s EDGE line (AEP Reference # 381700).

An internal investigation was completed and the root cause of the this MAC exceedance was the fact that vials/bottles used for sampling had been stored in a cabinet that formerly contained gasoline.

Our Water D&T management will be conducting follow-up discussions with field crews on the importance of proper sampling technique as well as sample storage.

1.1.2 EDMONTON INCIDENT REPORT SUMMARY – July 2021

EPCOR AEP Incident Description Date of Incident Reference Number Number Following AEP’s Communication and Action Protocol for Failed Bacteriological Results in Drinking Water (2009), EPCOR arranged to flush the water main and then took four (4) samples at 17:00 hrs on July 20, 2021. One (1) sample was from the failed hydrant (H1691), and three (3) samples were outside of the isolated area. All sample points were flushed thoroughly prior to sampling. The sample taken from H1691 tested positive for total coliforms for the second time at a concentration of 1.0 organism /100mL. The other 3 samples taken outside of the isolated zone passed all lab sampling, indicating that there was no detectable coliform contamination present in the active water distribution network. AEP was notified on July 22, 2021 at 14:50 hrs of this second sample failure. On July 22, 2021 EPCOR isolated H1691 from the rest of the isolation zone and the hydrant was then super chlorinated. The rest of the water main isolation was extended slightly to include a different hydrant H1584 for flushing and sampling. On July 23, 2021 EPCOR began flushing the water main to prepare for sampling and a main break occurred. Water main flushing was completed July 25, 2021 and samples related to the main break were taken to the EPCOR QA lab. Results were ENV- received on July 27, 2021 which passed for all parameters. The main 20210720- was recommissioned July 27, 2021. Hydrant H1691 remained isolated 966081 from the distribution system and was flushed and re-sampled on July July 20, 2021 381476 27, 2021. Sample results for hydrant H1691 were reported on July 28, 2021 and passed for all parameters. Hydrant H1691 was placed back in service on July 28, 2021 at 15:28 hrs.

It is likely that the original source of coliforms was Hydrant 1691, since the problem appears to have resolved after this hydrant was super chlorinated. In addition, both of the failed samples were drawn from this hydrant, whereas two other hydrants produced passing samples from the same water main. It is unknown why this hydrant would have had coliforms present. A preliminary investigation was completed and all water sampling protocols were followed. A corrective action to improve the EPCOR standard operating procedures and communication of these updates is underway to avoid a recurrence of this type of incident. These changes will be made promptly and will be communicated to all crews impacted. In addition, corrective discussions have been held with the individuals directly involved in the incident.
