Did the brand new Triump plant close? That was what? 5-7 years old?Sioux City actually doesn’t smell anymore. Moving sewage treatment away from the only interstate and going from 2nd largest stock yards to no stock yards got rid of about 99% of the “smell”. Doubt the latter is a net positive for local economy, but no more smell.
I saw a guy fishing in a lake that used to be the sewer in “Sewer City” last time I was back.
