For air emissions, should we test according to all parameters in level 2 on questions 8 and 9 (particulate matter, NOx, Sox, etc) or only a few of the parameters?

From FEM 2023 onwards, facilities only need to measure the quantity and not the quality of air emissions.

Also, it is recommended that all facilities monitor and measure all possible air emissions from facility operations. As such, if the facility does not emit any of the pollutant types, it is not required to measure quantities.

Facilities can always analyze whether they are emitting certain types of air emissions to ensure that all such air pollutants are measured and controlled. Guidance to this can also be obtained from industry guidelines specific to the facility type and process.
