I'm not so sure now that ammonium nitrate has been ruled out completely. At the beginning of the investigation, the anhydrous ammonia tanks and the rail car w/ammonium nitrate turned on its side from the blast, were ruled out as cause. Don't recall reading anything officially that might have been in the building that was on fire, just they were trying to figure out all of the different chemicals at the plant. Chances are all that paperwork was in one of those buildings, unless there was another set offsite. If not, it will have to be reconstructed. The Austin hearing articles gave the idea the questioners kept thinking ammonium nitrate, while the state fire marshal and assistant weren't saying, except its still a crime scene basically. I've not seen a real number for the amount of ammonium nitrate, mainly the number most often mentioned was a Feb. total. Patterson said the plant had been busy with farmers coming in for supplies. I live in Caldwell Cnty, and seeds were being planted here in Feb, some fields are still being planted, but West is approx 150 mi further north. The plant was 60 yr old and not one person, officials to townsfolk, thought something like this could/would happen. The State Chemist, Herrmann, is on record saying this plant has a better record than others that are this size. I've seen quite a few numbers batted around, so not sure how many plants (all sizes) are in TX, but do remember one of the Dallas articles saying the other the size of this plant is somewhere in the Panhandle. The double speak appears to be happening between those investigating vs the hearing officials and reporters. Something Adair (plant owner) said, even though his lawyers had advised him to not say anything, was the media had been giving some false information. What is the false information?
