The Energy Resources Conservation Board (ERCB) hereby advises pipeline licensees that high streamflow advisories, flood watches, or flood warnings have been issued for several areas of Alberta. High water levels have abruptly occurred due to significant rainfall combined with the melting of this year’s thick snowpack.
High streamflows and flooding have the potential to rapidly scour and wash out pipeline crossings of creeks, streams, and rivers. All licensees with pipelines crossing water bodies are expected to immediately apply extra operational diligence by
This extra operational diligence should be adopted through the spring and early summer melt and run-off periods, in addition to the normal surveillance mandated by the Pipeline Regulation.
The ERCB is aware that high streamflows may make pipeline crossing surveillance difficult or impossible at this time. In such cases, licensees are encouraged to isolate and purge pipelines where they may be at risk.
Up-to-date advisories on current emergency conditions can be obtained from the Government of Alberta’s Emergency Alert web page at www.emergencyalert.alberta.ca.
Specific water advisories and warnings can be obtained from www.environment.alberta.ca/forecasting/advisories.
