Ajinomoto Health & Nutrition North America Inc. has agreed to pay $458,265 in civil penalties and implement safety measures to address alleged violations of environmental laws at its Eddyville, Iowa facilities. The U.S. Environmental Protection Agency (EPA) conducted inspections following hazardous chemical releases that led to evacuations and shelter-in-place orders for the community.
The EPA highlighted two incidents: a hydrochloric acid release in 2021 and a chlorine gas release in 2022, which resulted in injuries. Chlorine gas is recognized as a dangerous substance due to its potential to cause severe health issues or fatalities upon inhalation.
"Ajinomoto’s operations presented a significant risk to its workers and the surrounding community," stated David Cozad, Director of the EPA Region 7 Enforcement and Compliance Division. He noted that the settlement involves installing an anhydrous ammonia containment system aimed at reducing risks for workers and residents.
Ajinomoto operates two amino acid manufacturing facilities that serve the food, beverage, and animal nutrition sectors. These facilities utilize chemicals such as anhydrous ammonia, hydrochloric acid, and phosphoric acid, classified by the EPA as "extremely hazardous substances."
The EPA alleges several violations by Ajinomoto:
- Failing to identify hazards from chemical releases.
- Not maintaining safe facilities or preventing hazardous releases.
- Inadequate hazard analysis for potential chemical releases.
- Non-compliance with mechanical integrity requirements.
- Poor coordination with local emergency planning organizations.
- Failure to report hazardous chemical use to local authorities.
As part of the resolution, Ajinomoto will install an ammonia water deluge system at one facility at a cost of approximately $227,589. This project aims to mitigate anhydrous ammonia releases into the environment. Additionally, Ajinomoto conducted a compliance audit to address any outstanding legal noncompliance issues.
Facilities handling toxic or flammable substances must adhere to Clean Air Act regulations. The law's General Duty Clause holds facility operators accountable for safe chemical management. Facilities are also required under the Risk Management Plan Rule to develop plans outlining accident prevention steps and emergency response procedures.
EPCRA mandates reporting from facilities managing hazardous chemicals, assisting communities in preparing for emergencies and informing them about potential risks.
