Observations (no outstanding follow-up required)

Observation 1 - Decommissioning sites

Date & time of visit: 2021-10-14 15:20

Discipline: Environmental Protection




General observation for the following sites:

The Inspection Officer (IO) and accompanying IAMC Indigenous Monitors (IMs) visited the sites noted above. The decommissioning work at all the sites was completed and restoration was also completed. Sites were either seeded with seed mix requested by the landowner or left unseeded for spring farming activities. No concerns noted.

The IOs and IMs also visited the Gretna Terminal and inspected the Line 3 decommissioning activities at the Terminal. Three distinct sites were visited. Excavated areas were being actively pumped to keep water out. Filter bags were installed on the outlets and water was being tested (visually and field measurements of physical properties) prior to discharge into the terminal's surface water system. 

Compliance tool used: No compliance tool used

Observation 2 - Meeting with Slave Lake First Nation Chief and Council

Discipline: Socio-Economic




The inspection team met with the new Chief and council members of the Swan Lake First Nation (SLFN). The Chief raised three main concerns.

The first concern was with nearby contaminated sites being managed by Enbridge and regulated by the CER. These sites are off reserve, but are upstream of the water supply of the Nation. SLFN leadership needs more information and assurance that the remediation sites are not affecting their water supply. Enbridge committed to meet with the SLFN to provide a status update on the remediation work.

The second concern was specific to the decommissioning site on the reserve. The company committed to have a SLFN monitor attend the sites and observe various activities. Unfortunately, due to some miss communication, Enbridge PipeLine Maintenance (PLM) crew cut the pipe and capped it without the presence of the SLFN monitor. The monitor was able to observe various other activities at the site, but not the actual cut and cap. (See IR #1)

The third concern was related to the long term relationship between the company and the Nation. Enbridge committed to meet with leadership. A meeting was already planned for the following week.
