Dyno Nobel pays fine, addresses EPA violations at plant

CHEYENNE (WNE) — On Tuesday, the U.S. Environmental Protection Agency (EPA) announced a Clean Air Act settlement in which Dyno Nobel, Inc. has agreed to pay a $394,906 civil administrative penalty as part of an ongoing, multi-step effort to address violations of Risk Management Program (RMP) requirements at the company’s ammonium nitrate production plant in Cheyenne.

An EPA inspection of the Dyno Nobel facility revealed several violations of RMP requirements related to the management of ammonia and chlorine.

“EPA continues to protect communities by ensuring that facilities that handle hazardous chemicals such as ammonia and chlorine comply with the safety requirements intended to prevent accidents,” said Suzanne Bohan, director of EPA Region 8’s Enforcement and Compliance Assurance Division, in a news release. “The measures Dyno Nobel has taken in response to EPA’s compliance actions are significantly reducing the risks of chemical releases that can harm residents, workers and first responders.”

The Dyno Nobel facility is subject to Clean Air Act RMP regulations because it stores and processes large quantities of ammonia and chlorine.
