Waste sitting in pits could fill almost 883,000 Olympic-size swimming pools, and oil companies say they need to find a way to reduce it

The companies, including an affiliate of Exxon Mobil, are lobbying the Canadian government to set rules that would allow them to treat the waste and release it into the Athabasca River by 2025, so they have enough time to meet their commitments to eventually close the mines.

Of course they are.
