Suncor admits to releasing 150 times the limit of sulfur dioxide

​COMMERCE CITY, COLO. - In a letter to the state sent last week, the Suncor oil refinery in admitted it released more than the reportable limit of sulfur dioxide when power went out at the plant back on October 14.

At the time, the company said the orange cloud was not hazardous. And it still insists the same in that letter, “there are no known or anticipated acute or chronic health risks associated with the release, and there is no need.”

But in that letter, Suncor also admits that it released more than the reportable quantity of 500 pounds of sulfur dioxide. It, in fact, estimates a total of 37.8 tons of sulfur dioxide was released. That’s more than 75,000 pounds.
