Texas fertilizer company didn't heed disclosure rules
Apart from the DHS, the West Fertilizer site was subject to a hodgepodge of regulation by the EPA, OSHA, the U.S. Department of Transportation, the Texas Department of State Health Services, the Texas Commission on Environmental Quality and the Office of the Texas State Chemist.
But the material is exempt from some mainstays of U.S. chemicals safety programs. For instance, the EPA's Risk Management Program (RMP) requires companies to submit plans describing their handling and storage of certain hazardous chemicals. Ammonium nitrate is not among the chemicals that must be reported.
In its RMP filings, West Fertilizer reported on its storage of anhydrous ammonia and said that it did not expect a fire or explosion to affect the facility, even in a worst-case scenario. And it had not installed safeguards such as blast walls around the plant.
A separate EPA program, known as Tier II, requires reporting of ammonium nitrate and other hazardous chemicals stored above certain quantities. Tier II reports are submitted to local fire departments and emergency planning and response groups to help them plan for and respond to chemical disasters. In Texas, the reports are collected by the Department of State Health Services. Over the last seven years, according to reports West Fertilizer filed, 2012 was the only time the company stored ammonium nitrate at the facility.
It reported having 270 tons on site.
"That's just a god awful amount of ammonium nitrate," said Bryan Haywood, the owner of a hazardous chemical consulting firm in Milford, Ohio. "If they were doing that, I would hope they would have gotten outside help."
In response to a request from Reuters, Haywood, who has been a safety engineer for 17 years, reviewed West Fertilizer's Tier II sheets from the last six years. He said he found several items that should have triggered the attention of local emergency planning authorities - most notably the sudden appearance of a large amount of ammonium nitrate in 2012.
"As a former HAZMAT coordinator, that would have been a red flag for me," said Haywood, referring to hazardous materials.
