Canadian Agency Urges Stricter Rules for Oil Sands Water Removal

Study reflects concern that industry's massive appetite for water threatens the health of Alberta's Lower Athabasca River

A new study is raising questions and exposing flaws in the way Canada and the province of Alberta are managing the oil sands industry's massive appetite for water.

The federal (DFO) evaluated technical reports on the health of the Lower Athabasca River, the main source of water for oil sands mines in the northern half of the province.

The , released last week, said oil sands operators should limit water withdrawals from the river when flows are low or risk causing "serious or irreversible" harm to fisheries.

There was "concurrence that a flow should be established for the Lower Athabasca River below which there would be no water withdrawal," the DFO scientists said. "This flow should be established using a precautionary approach, based on the best available science."

The conclusion reflects mounting concern in government ranks that the industry's growing water consumption is having potentially dangerous impacts on the river's health and instream flows.

Environmental groups applauded the study.

"It is a critically important report to come out of the federal government," said Bill Donahue, special water policy adviser for , an Alberta-based nonprofit group.

It "makes it clear that at the very least the federal government cannot now deny that the river is likely not adequately protected," he told SolveClimate News.

The Alberta government has committed to setting a new water policy for the Athabasca River in 2011. Conservationists are cautiously optimistic that the DFO's "cutoff" recommendation will make it in.

"I'm quite confident, given the rising attention to this issue nationally, that governments will see their way through to embedding this in the plan for the Athabasca River," Tony Maas, director of the Freshwater Program at environmental group , told SolveClimate News. "It remains to be seen, though."

A spokesperson for , a department of the provincial government, said it is too early to tell if stricter water withdrawal rules will be adopted.

"The DFO is working with Alberta Environment on developing the phase two of the water management framework that's currently on the river," Jessica Potter told SolveClimate News. "Right now we're in the middle of exploring a variety of options. It's far too soon to speculate what's going to be the final result."

Current Policy Not Enough, Groups Say

In 2006, the oil sands industry was allowed to draw 2.3 billion barrels each year from the Athabasca River—enough to supply about two Calgary-sized cities.

Winter flows in the river can shrink to 10 percent of spring and summer flows. To police the industry during critical times, Alberta's current water policy, the , rates flows as green, yellow and red. Under "red" conditions in the wintertime, companies are required to withdraw less.

"As it stands right now, we have very strict withdrawal limits on what oil sands can take from the river," Potter said. "The idea of putting restrictions isn't new, considering we already have them in place."

But environmental observers say the current policy doesn't go far enough.

"No matter how low the flow in the river gets, there's still withdrawal," Donahue said.

Canada's oil sands represent the largest crude deposits outside the Middle East. Water plays a crucial role in separating the buried tar, known as bitumen, from sand and clay.

It can take 2.5 to 4 barrels of water to obtain each barrel of the bitumen, according to estimates from the , a Canadian research organization. Currently, less than 10 percent of water is returned to the river, the institute says.
