St. Helens, OR – Dyno Nobel, Inc. has completed a two-year probationary period and paid a $250,000 fine following a guilty plea to federal environmental crimes stemming from a series of significant ammonia releases at its St. Helens, Oregon manufacturing plant in the summer of 2015. The case, prosecuted under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), highlights a pattern of delayed reporting and a failure to adequately address a hazardous substance release impacting the surrounding community.
According to court documents and the company’s plea agreement, the Dyno Nobel facility discharged over six tons of anhydrous ammonia vapor into the atmosphere over a three-day period beginning July 30, 2015. The releases originated from multiple failed attempts to restart the plant’s urea production line. Residents of nearby Columbia City, Oregon, reported a barrage of symptoms, including strong foul odors, eye irritation, and respiratory distress, triggering numerous complaints to local authorities.
Despite internal awareness of the excessive ammonia emissions, Dyno Nobel personnel failed to notify the National Response Center – the federal point of contact for reporting hazardous substance releases – for over a week. The company finally reported the incident on August 7, 2015, a clear violation of federal law which mandates “immediate” reporting of such events. This delay significantly hampered potential mitigation efforts and prolonged the exposure of the public to the hazardous air pollutant.
Investigation and Legal Ramifications
The Environmental Protection Agency (EPA) launched a comprehensive investigation into the incident, uncovering the series of operational failures and the subsequent failure to adhere to legally mandated reporting requirements. The investigation revealed a systemic issue with the plant’s restart procedures and a lack of proactive measures to prevent and address hazardous releases. Federal prosecutors ultimately charged Dyno Nobel with one count of violating section 103(b) of CERCLA, codified as 42 U.S.C. 9603(a)(b).
On February 23, 2018, Dyno Nobel, Inc. formally pleaded guilty to the charge. In June of the same year, the company was sentenced by a federal judge to pay a $250,000 fine and serve a two-year term of probation. The probationary period, which has now concluded, required the company to implement enhanced environmental compliance programs and undergo regular audits to prevent future incidents.
Community Impact and Ongoing Concerns
The case has raised concerns among environmental advocacy groups and local residents regarding industrial accountability and the potential health impacts of hazardous air pollution. While Dyno Nobel has fulfilled the terms of its sentence, questions remain about the long-term effects of the ammonia exposure on the community. GrimyTimes will continue to monitor industrial activity in the region and report on any further environmental violations.
