CAUSE OF RELEASE IMMEDIATE RESPONSE PLANS TO PREVENT SIMILAR RELEASE? WRITTEN REPORT REQUESTED?

ASSET MANAGEMENT & PUBLIC WORKS DEPARTMENT – DRAINAGE SERVICES BRANCH – Wastewater Treatment AE 197868 February 27 @ 10:15 Gold Bar WWTP – Digester 6

1000 cubic metres Digester Biogas (Not contained)

As part of 2008 plant maintenance, Digester #6 was removed from service and prepared for scheduled maintenance. The preparation involved the purging of the headspace of digester biogas with nitrogen and venting to the atmosphere.

No action taken as this was a planned maintenance activity.

As much Biogas as possible is removed from the headspace prior to the nitrogen displacement and venting. AE: Yes

AE 199219 April 2 @ 10:00 Digester Gas Room #2 Goldbar WWTP

1 cubic metre/8 ppm Digester Biogas (Not contained)

Controlled bleed off to atmosphere from the mixing compressors discharge header line to the digester mixing header. Need to install a blind between 2 flanges for proper isolation.

A 0.5 inch hose was directed outside to atmosphere to bleed off any possible gas in the line. The line was purged.

Install a blind between the 2 flanges to ensure proper isolation. AE: Yes

AE 201184 May 21 @ 07:39 Goldbar WWTP

2 Megalitres Partially treated sewage (Not contained)

Planned power switch over from Hardisty to Kennedale.

On both days, as power was being restored throughout the waste water treatment plant the UV system gradually came back on. Within a few minutes of the initial power disruption the UV disinfection system was back in full operation.

This switch was required for maintenance purposes and was planned well in advance with EPCOR. AE: Yes

AE 201869 May 22 @ 06:50 Goldbar WWTP


Planned power outage for the wastewater treatment plant to accommodate a switch from the main electrical power feeder to the backup feeder, then back to the main feeder the following day.

On both days, as power was being restored throughout the waste water treatment plant the UV system gradually came back on. Within a few minutes of the initial power disruption the UV disinfection system was back in full operation.

This switch was required for maintenance purposes and was planned well in advance with EPCOR. AE: Yes

AE 203228 July 5 @ 15:20 GoldBar WWTP 10977 – 50 Street

Unknown – small amount Partially treated wastewater (Not contained)

After heavy rainfall, Grit tanks 1 & 2 overflowed as crew was unable to open Grit #3 Influent Channel gate. This caused spillage onto road into catch basins connected to Bypass Outfall.

N/A Grit tank 3 will be cleaned more frequently during digester 6 cleaning activities. AE: Yes

AE 203838 July 8 @ 21:42 10977 – 50 Street Gold Bar WWTP

0.32 Megalitre Untreated wastewater 9.0 ML partially treated wastewater (Not contained)

Channel 2 overflowed static weir prior to reaching 910 ML/day – primary treatment capacity.

N/A Ease influent channel and primaries 7 & 8 will be put back into service once isolation gate installation is completed. AE: Yes

CAUSE OF RELEASE IMMEDIATE RESPONSE PLANS TO PREVENT SIMILAR RELEASE? WRITTEN REPORT REQUESTED?

ASSET MANAGEMENT & PUBLIC WORKS DEPARTMENT – DRAINAGE SERVICES BRANCH – Wastewater Treatment (continued) AE 203406 June 15 @ 14:10 (reported to AE on July 8 @ 14:30 10977 – 50 Street Gold Bar WWTP

1 Megalitre Partially treated wastewater (Not contained)

Sustained influent flow of 420 – 450 ML/day (due to rain) Flow transmitter indicated <420 ML/day when secondary bypass initiated.

N/A Ensure secondary bypasses only initiated once final effluent flow meter reaches 420 ML/day. AE: Yes

AE 203433 July 9 @ 13:30 10977 – 50 Street Gold Bar WWTP

3.4 MegaLitres Partially Treated Sewage (Not contained)

East primary influent channel and primaries 5-8 out of service for gate installation. Primaries 1-4 and 9-12 in service for rated capacity of >910 ML/day.

Pump used to minimize overflow of primary effluent into EPE distribution chamber.

Gates at EPE distribution chamber to be extended to prevent future overflows. AE: Yes

AE 204914 August 18 @ 07:53 Gold Bar WWTP 10977 – 50 Street

2.8 Megalitres Partially treated sewage (Not contained)

Pre-arranged with EPCOR scheduled shut down – power feed switched to backup feeder and then back the next day.

Required for maintenance purposes. Well planned in advance with EPCOR.

AE was informed of the planned power outage that would cause a small volume of un-disinfected effluent to enter the river. AE: Yes

AE 205112 August 19 @ 07:28 Gold Bar WWTP 10977 – 50 Street


Pre-arranged with EPCOR scheduled shut down – power feed switched to backup feeder and then back the next day.

Collection Date Collected By Sampling Site Problem Action Taken

31-Jan KG MPW

Less than 1 L collected because carboy was not lined up under nozzle properly.

Sample results reported as NS (no sample) and SAP written to add a bracket to back of fridge door to keep carboy in correct position.

1-Apr CM FEC

Sampler was restarted and somehow carboy's ended up in wrong position. In morning, sampling into Tuesday instead of Wednesday, which already had 8 L and Tuesday had only 5L. Sample for 01 & 02 were mixed.

Sample from both carboys were mixed together and registered as Tuesday April 1 sample and all results were reported as estimates. Nonconformance report completed.

July 24-25 n/a RawSampling suspended because of sampling for Gold Bar Model Development Testing. none

25-Jul n/a PESampling suspended because of sampling for Gold Bar Model Development Testing. none

Aug 30-31 SJ RawSampler plugged

none, Sampler was left plugged until MH returned Sep 2, 2008 when he unplugged it. Non-conformance report filled out.

12-Aug BN/KG PE

Sample chamber's wing nuts not tightened properly, vacuum too weak because of improper seal.

KG investigated and tightened wing nuts, MH filled out non-conformance Sept 2, 2008

Aug 14-28 n/a MPWSampler shutdown for maintenance in Membrane Water Plant.

No samples taken until notified by Brad Salter that sampler had been re-activated.

26-Sep BN Raw Sampler arm mis-aligned KG re-aligned arm, non-conformance reported and NS recorded.

13-Sep ES PE

Sample chamber's wing nuts not tightened properly, vacuum too weak because of improper seal.

ES investigated and tightened wing nuts, non-conformance reported, NS recorded.

Nov 8 to Nov 12 Various RawRefrigerator leaked refrigerant, sample temperature too high.

Informed Brad Salter and he had repaired. Estimated results for the 5 days.

26-Nov MH PEPower outage caused clock to be out. Samples mixed on Nov 27th. Restarted sampler.

18-Nov BN FEC

Low sample volume. Maintenance installed a hose that was too short to reach FEC supply.

Replaced hose immediately, told BN to insure hoses labelled properly. Enough sample was collected for it to be considered representative.

4-Nov BN MPW

Sample temperature too high, fridge turned off for defrosting.

Non-conformance written, samples to be reported as estimates, techs doing defrosting will create reminders to insure fridge is turned back on as soon as possible.
