After a complaint in 2006 about an ammonia smell coming from the facility, the Texas Commission on Environmental Quality investigated and cited the operator for not having obtained a permit for its two storage tanks containing anhydrous ammonia. A permit was issued once the operators brought the facility into accord with agency regulations and recommendations. Also in 2006, the EPA fined the owners $2,300 for problems that included a failure to file a risk management program plan on time. In June 2012, the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration further fined the facility $5,250 for violations regarding its storage of anhydrous ammonia.
