Not sure what that means but from the road closures and prep, it's not good.

Any info or insight would be welcomed.

SO2 equals a dirt nap.

SummerSneeze : I think SO2 is more of an irritant; are you thinking of H2S? Hydrogen Sulfide is often what kills plant workers.

AI: H2S is known for its rotten egg smell, while SO2 has a pungent, suffocating odor.

Skippy :
Good luck with "rotten eggs" when attempting to smell H2S. Matter of fact good luck with smelling anything post experiencing H2S…

WORROW :
That was AI talking. Maybe it was confusing H2S and Mercaptans.
