For your information the pollution plume of No2 which converts to Nox ( Nitric Acid & Nitrous Acid) when mixed with water/dew. With the current  yearly estimate of 1,128 tons emitting from the plant

and thermal inversions of roughly 90 odd days per year trapping the emissions to the ground it would far exceed the emission standards of Health Canada for daily exposure for the school & arena children & residents. The attached document will address a best practise way of removing some of the possible additional No2 which I understand could be forthcoming on top of this figure or at least migrate the issue slightly if the company practises best methods.
