You're not from around here. Irwindale is in the middle of nowhere, next to a freeway and a rock quarry.
The AQMD is one of the shadiest governmental agencies there is - apparently their main function is to demand enough shakedown money from SoCal businesses so they leave town.
The AQMD actually inspected the plant several times...and found nothing wrong. The complaints about the smell originated from an Irwindale councilman's son.
