CHERRY CREEK, B.C. — The gypsum recovery efforts underwater and on the embankment of the Canadian Pacific Kansas City (CPKC) derailment site along Kamloops Lake are mostly complete as crews stand down for the winter. 


In an update Friday (Dec. 5), the B.C. government says most shoreline segments, including those adjacent to the community of Frederick, have been deemed successfully treated by a Shoreline Cleanup Assessment Team. 

However, the province notes that two areas of the shoreline remain incomplete due to safety concerns and rising water levels. The two areas will be reassessed in the spring. 

“Operations are transitioning to an overwintering phase with permanent boom containment installed at the derailment site,” the province states. “No additional sheening has been observed in the area, and ongoing weekly monitoring will continue from the Responsible Party’s contractor.” 

Routine water sampling from the portion of Kamloops Lake has also been suspended as the province says water quality monitoring has shown results of non-detection. The latest sampling held on Dec. 1 showed no hydrocarbons, according to the province. 

Additionally, the province says a long-term monitoring plan is being developed as contractors assisting in the cleanup of Kamloops Lake demobilize most of their onsite presence. 

CPKC said a rockslide may be partially to blame for the Nov. 1 derailment that resulted in the spill of more than 70,000 litres of aviation fuel alongside Kamloops Lake. 

A total of 17 railcars went off the tracks near Cherry Creek. Four railcars were loaded with fuel, five contained gypsum and one was carrying pulp. While the others were empty, three cars had previously contained gasoline. 

The last remaining railcar was removed from the site on Monday (Nov. 10). CPKC says there were no injuries reported from the derailment.

The province says no further updates are expected.
