Carbon monoxide exceedance at Durham York Energy Centre

Posted on Monday July 22, 2019

Whitby, Ontario – On Saturday, July 20, an external electrical power trip and subsequent recovery procedures led to an exceedance of the four-hour rolling average limit for carbon monoxide (CO) at the Durham York Energy Centre (DYEC).

The limit for CO is set at 40 mg/Rm3 (milligrams per reference cubic metre), which is a Performance Requirement under Schedule C of the Environmental Compliance Approval (ECA). The CO levels were 55 mg/Rm3. CO is monitored as an operational parameter indicating combustion performance. All other emissions were in compliance.
