Covanta’s incinerator in Courtice has run into a snag again.
Late last week, the company that built and is operating the energy-from-waste centre for Durham and York regions, shut down a boiler at the plant after it failed a recent stack test. Lab results showed air emissions from the boiler exceeded the recommended limit for dioxins and furans. The limit is 60 and it tested at 818.
(The test measures emissions from more than 200 parameters.)
James Regan, director of communications and media relations for Covanta, said the decision was made “after careful consideration and consultation with staff at Durham Region.”
Both he and Dr. Robert Kyle, medical officer of health for Durham, stressed the high results don’t represent a risk to human health or the environment.
At the same time, the second boiler at the plant came through the stack test just fine with a result of 12. So it continues to operate, burning garbage and producing energy.
Mr. Regan noted Covanta will be investigating the root cause of the results and a retest will be scheduled soon.
He said the company wants to verify the first results from a lab in Mississauga. The company had requested a lab in North Carolina but regional council did not agree with that.
