A new report from , a financial research firm, warns investors that some leading oil sands companies may be particularly exposed to financial risk from toxic waste water liabilities.
The report attempts to quantify the true cost of cleaning up billions of barrels of contaminated water resulting from the mining and refining operations of leading producers of oil sands crude. It was quietly released in December to RiskMetrics' private clients, and unveiled more publicly last week in a . Titled "Oil Sands Tailings Pond Remediation Costs Understated," the report shows a handful of companies to be at a financial disadvantage because of their exposure to waste water remediation liabilities.
For example, for Suncor, currently the largest producer in the oil sands, water remediation could cost almost $2 million a week, or $104 million a year, according to RiskMetrics. That would erode the company's annual net income by 26 percent according to RiskMetrics' low-cost analysis. In the worst case, RiskMetrics says, the cost of cleaning up toxic waste water could completely wipe out Suncor's earnings.
In contrast, the super majors, like Exxon and Chevron, can easily absorb the clean-up costs because of their enormous size and diversified holdings.
"Many investors were really glad to see the report," Yulia Reuter, the author, told SolveClimate. "They have known that tailing pond remediation was a problem. Now, they can see something specific that quantifies the financial risk."
Reuter explained that oil sands producers have been setting aside debt obligations on their balance sheets in the knowledge that they would one day have to pay the cost of waste water clean-up. Her analysis, however, reveals that the set-aside calculations have been insufficient to cover the full cost and that ongoing clean-up could substantially erode earnings of the most overexposed companies.
Each barrel of oil that comes out of the oil sands requires as much as four barrels of to extract, water that is contaminated with toxic tailings in the process and disposed of in giant containment ponds. Since February 2009, companies have been under government orders to clean the toxic tailings out of the water left behind. Alberta's Energy Resources Conservation Board (ERCB) issued , which requires oil producers to address a problem that has been growing without a solution for decades. Existing "tailings ponds" now cover , including once-pristine boreal forest.
The directive requires producers to process fluid tailings, transform them into solid "fines" — mineral solids with particle sizes equal to or less than 44 micrometers — and deposit them in dedicated disposal areas that must become trafficable within 5 years. A first baseline survey is due from all oil sands developers by the end of this September, followed by a gradual phase-in over three years of the directive's regulations.
Non-compliance could theoretically result in a shut-down of mining and refining operations. However, observers believe that would be highly unlikely. The ERCB has historically enjoyed a cozy relationship with the oil sands industry — a lynchpin of the Canadian economy. If producers go into default, they more likely would face a fine or restrictions on permits for expanded operations, Reuter said. Compliance with Directive 74 is negotiated on a case-by-case basis.
Super Majors Have an Advantage
The new regulatory measures are unlikely by themselves to slow the growth of oil sands production, already about . That's because the super major oil companies can absorb the cost of cleaning-up toxic waste water without recording a noticeable erosion of profits, according to the RiskMetrics analysis.
