4 1.1.1 Operations Rossdale and E.L. Smith Plants Plant Bypasses The number of bypasses shown on Table Rossdale Waste Stream Data and Table 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 to be unplanned. In September, Rossdale Plant had two planned and two unplanned bypasses or shutdowns. Date Type Bypass Description Sep 19 th Planned 11.5 hour shutdown due to Capital project work Sep 21st Unplanned 2.5 hour bypass due to power outage Sep 24 th Planned Plant 1 shut down for Maintenance work Sep 24 th Unplanned 2 hour bypass due to power outage In September, E.L. Smith Plant had one planned and one unplanned bypasses or shutdown. Date Type Bypass Description Sep 11 th Unplanned 1 hour 10 minute bypass due to a PLC comm issue Sep 12 th Planned 23 hour shutdown for Capital work and Maintenance PM s Clarifier Blowdown Volume The clarifier blowdown volume shown on Table and Table include estimated plant leakage. Dechlorination Highlights During the month of September there were zero instances of chlorinated waste released at the outfall structure at Rossdale Water Treatment Plant. During the month of September there were zero instances of chlorinated waste released at the outfall structure at E.L. Smith Water Treatment Plant. Chemical Dosing Highlights In September, Rossdale and E.L. Smith Water Treatment Plants did not exceed the imum 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.

5 1.1.2 EDMONTON INCIDENT REPORT SUMMARY EPCOR Incident Number Description Date of Incident AEP Reference Number ENV Samples were collected upon commissioning of a water main renewal project at 142 nd Street and 104 th Avenue in Edmonton. Results came back positive for Total Coliforms and it was determined that the Contractor had not followed proper chlorination practices prior to flushing and sampling. Additional samples were collected after further chlorination and all sample results were negative for Total Coliforms. 1-SEP
