Emissions Data

Emissions from the Durham York Energy Centre (DYEC) are recorded by the continuous emissions monitoring system (CEMS). Emissions data is also collected during source (stack) tests.

Continuous emissions data on this web page is collected by the facility’s Digital Control System (DCS) and automatically posted as close to real time as possible for information purposes. Data has not undergone final verification or complete quality control and quality assurance procedure; therefore, this data should not be used in published documents. Final verification and quality control procedures are undertaken on regular basis and are stored on the DCS master log for regulatory purposes.

All data is based on a 24 hour rolling average, except for the following:

  • Carbon Monoxide (CO) - 4 hour rolling average;
  • Opacity (5%) - 2 hour rolling average; and
  • Furnace Temperature and Oxygen (O2) - hourly average.
