Environment Hamilton has released new stack keys.

A C&P from their web site.
"Environment Hamilton has designed stack keys to help Hamiltonians to call in concerns regarding visible air emissions from stacks in Hamilton's industrial core.

The general rule of thumb when stack watching is that if you can see visible emissions coming from a stack (not steam but discoloured discharges of a black, brown, green, or orangy-red colour) then it is very likely that the stack emission that you are viewing is in violation of provincial air quality regulations.'
