ITD modified its original permit based on residents’ concerns over noise pollution generated from the shredding operation. Instead of a diesel operated shredder, the facility will now utilize an electrically powered “chomper.” Additionally, the “chomper” will be housed in an intermodal container, which will have a sound dampening effect.
ITD’s anticipated sound levels will likely be lower than that generated by daily Amtrak and freight trains at the Hamlet CSX facility. By comparison, a shredder has a decibel scale (henceforth, dBA) of roughly 75, whereas a freight train has a dBA of 80. The horn on a train is roughly 130 dBA.
