I reported this issue last year. There is an intermittent, disgusting chemical odor that appears and disappears in the area between
Covidien and Sims Metal Management. It smells acetone-based. Thursday night it was very strong and wafted over the highway as I drove home. There was enough smoke/steam coming from Sims Metal Management to obstruct vision on the highway (about 7:40pm). Not sure if they are related. I reported this to the State and to the Town of North Haven to no avail. Honestly, it smells like cancer. Ick.
