That report makes an interesting note about risk management:
"Separately, the plant had informed the Environmental Protection Agency that it presented no risk of fire or explosion, according to The Dallas Morning News. It did so in an emergency planning report required of facilities that use toxic or hazardous chemicals.
The plant's report to the EPA said even a worst-case scenario wouldn't be that dire: there would be a 10-minute release of ammonia gas that wouldn't kill or injure anyone, the newspaper reported."I wonder if a better risk assessment & mitigation plans could have made a difference.
