Texas Chemical Plant Cited $1.4 Million for Acid Waste Violations

Air Products LLC has agreed to pay $1.485 million in civil penalties to resolve hazardous waste mismanagement violations at its Pasadena, Texas, chemical manufacturing facility, the Justice Department, the Environmental Protection Agency (EPA) and the state of Texas recently announced. The settlement resolves Air Products’ Resource Conservation and Recovery Act (RCRA) violations in transferring spent acid to the neighboring Agrifos Fertilizer Inc. manufacturing plant.

"This settlement eliminates the disposal of spent-acid waste from the Air Products facility into the environment," said Ignacia S. Moreno, assistant attorney general of the Justice Department’s Environment and Natural Resources Division. "By stopping this source of pollution, this settlement will reduce risks to human health and the environment."

Air Products, a manufacturer of chemicals used in the manufacture of polyurethane and hydrogen gas, operates its facility on a 105-acre tract of property adjacent to the Agrifos fertilizer plant. For many years, the company purchased sulfuric acid from Agrifos and returned a spent acid stream that Air Products had generated in its operations. In April 2006, inspectors from EPA observed that the return acid stream was a spent acid that was being used in part to make land-applied fertilizer. Agrifos is not authorized to accept hazardous waste from other facilities.

"We are concerned that wastes from mineral processing and associated fertilizer production can pose a serious risk to our nation’s drinking water and the health of families," said Cynthia Giles, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance. "And we’re just as concerned when contaminated wastes from other facilities find their way to these operations.”

Air Products instituted modifications that will reduce the levels of contamination in the spent acid, and the construction of a $60 million regeneration plant that will stop the acid waste stream altogether. The regeneration plant construction was part of operational changes that were initiated prior to settlement negotiations and became effective as negotiations progressed.

This case is part of EPA’s National Enforcement Initiative for Mining and Mineral Processing. Although Air Products does not conduct mining or mineral processing, it sent the spent acid stream to a facility that does – the Agrifos fertilizer plant. Mining and mineral processing facilities generate more toxic and hazardous waste than any other industrial sector, based on EPA’s Toxic Release Inventory.

A 2007 incident at the Agrifos phosphoric acid facility in Houston released 50 million gallons of acidic hazardous wastewater into the Houston Ship Channel.
