New data suggests Alberta oilsands causing acid rain in SaskatchewanBy BOB WEBER Environmentalists want Ottawa to set caps on emissions from Alberta’s oilsands that are likely responsible for acid rain falling over northern Saskatchewan’s pristine rivers and lakes. “It’s not just regulation on every individual plant that’s needed. There also needs to be a regional cap that’s established for the industry,” said Peter Prebble of the Saskatchewan Environmental Society. “The federal government has the authority to do so.” Alberta’s oilsands are located just west of the boundary between the two provinces. The massive industrial plants emit more than 150,000 tonnes of acid-rain-causing gases every year and previous studies have suggested that about 70 per cent of those gases blow into Saskatchewan. The province has been monitoring rainfall in the La Loche area just across from Fort McMurray. Results from nine samples over 18 months that ended last March showed an average pH level of 4.93. That level is about three times as acidic as unpolluted rainfall and about the same acidity as a cup of black coffee. “We do have concerns and have been putting significant resources in to determine what the baseline situation is up there,” said Murray Hilderman, air policy analyst for Saskatchewan Environment. He cautions that the data so far is limited. “We wouldn’t be able to get a trend with just a couple of years data,” Hilderman said. …
