I'm not sure which map you're looking at. Irwindale is located in LA county, one of the most populated areas of the US. Obviously if the smell didn't go very far it wouldn't be much of a problem.
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.
This comment sounds really condescending considering it sounds like you have never lived near LA to be that judgmental about any of your parent poster's supposed inaccuracies.
