Critics ask why Alberta sat on coal contamination data

Alberta sat on coal data

Critics are asking why Alberta Environment has been sitting on years worth of data about pollution from coal mines while the government considers a dramatic expansion of the industry.

"It raises some important questions about our ability to trust what's going on," said New Democrat environment critic Marlin Schmidt. "The fact (Alberta Environment) hasn't reported publicly is extremely concerning."

On Monday, The Canadian Press reported on analysis of coal mine contamination in the Gregg and McLeod Rivers and Luscar Creek near Jasper, Alta., dating back to the 1990s. It found toxic levels of selenium many times over the amount considered safe for aquatic life.

The Gregg and Luscar Creek mines closed in the early 2000s. Selenium levels from both declined,at best, only gradually over more than 15 years of remediation.

In the case of the Cheviot mine on the McLeod River, levels gradually grew between 2005 and 2017. The operation closed last June.

The data also shows the provincial government knew about the levels for at least 15 years and did not report anything after 2006. The information was available in raw form, but Schmidt said it isn't enough to simply collect information.

"There are numbers and then there are the numbers that the stories tell. That's the piece that's missing."

The New Democrats were in power for four of those years. Schmidt said sitting on the information is worse now because Alberta is going through a wrenching debate over the present government's plans to expand the industry by opening up the Rocky Mountains to open-pit, mountaintop coal mines -- an option that did not exist under the NDP.

"This data's relevance is more important now," he said.

Alberta Environment has pointed out that the raw data has always been public. Spokesman John Muir promised the province would soon release its own report on water downstream of coal mines.

Lack of action shows that monitoring often promised by industry and government as new projects are considered isn't enough, said Katie Morrison of the Canadian Parks and Wilderness Society.

"On those rivers we're seeing that monitoring hasn't been enough to actually control selenium. We just continue to promise monitoring. We didn't see action to bring those selenium numbers down."

A 2006 provincial report found that selenium was already harming fish. As well, a 2005 published study co-authored by provincial scientists found rainbow trout were suffering facial and skeletal deformities from selenium.

The province has recently sold about 1.4 million hectares of coal exploration leases. Hundreds of drill sites and kilometres of new roads have already been permitted on previously unmined mountainsides. One new coal mine, Benga Mining's Grassy Mountain project in the Crowsnest Pass in southwestern Alberta, is before a joint federal-provincial review.

The information on the old coal mines shows what's at issue for new ones, said Morrison.

"Those stakes are really high. (Selenium release) has been happening other places and they have not been able to get the selenium under control."
