Algoma Steel Inc. monitors local air quality through a network of ambient air quality monitoring stations which are operated and maintained by a third party.

Three stations located on Bonney Street, West and Cathcart Street and 4th Avenue monitor for a multitude of parameters on a continuous and non-continuous basis. A summary of the non-continuous monitoring results are provided in quarterly reports which are available on the Algoma website. The air quality parameters monitored continuously are summarized below and include the following:
Total Reduced Sulphur (TRS)
The Ministry of Environment, Conservation and Parks ambient air quality criterion for TRS is 7 micrograms per cubic metre (5 parts per billion) for a 24 hour period and 13 micrograms per cubic metre for a 10 minute period (10 parts per billion).
Sulphur Dioxide (SO2)
The Ministry of Environment, Conservation and Parks ambient air quality criterion for SO2 is 275 micrograms per cubic metre for a 24 hour period and 690 micrograms per cubic metre for a 1 hour period.
Particulate Matter smaller than 10 microns and 2.5 microns in diameter (PM10 and PM2.5)
The adopted Ministry of Environment, Conservation, and Parks interim ambient air quality criterion for PM10 is 50 micrograms per cubic metre for a 24-hour period, which is based on a Canada Wide Standard. There is no criterion for PM2.5.
