Hans Nilesen, Violating Clean Water Act, Missouri 2010

St. Joseph, MO – Hans Nilesen, a key figure in the pesticide manufacturing company HPI, faced criminal charges and penalties in 2010 for a series of egregious environmental violations. The case, investigated by the Environmental Protection Agency (EPA), revealed a pattern of illegal hazardous waste storage and disposal practices that threatened public health and the environment in St. Joseph, Missouri.

According to court documents, HPI knowingly violated both the Resource Conservation and Recovery Act (RCRA) and the Clean Water Act (CWA) during its pesticide production. Investigators discovered that the company was illegally storing hazardous waste at multiple, unpermitted locations throughout the city. More alarmingly, HPI was found to be directly discharging waste pesticides into the municipal sewer system, bypassing required treatment processes and contaminating waterways.

The legal proceedings began on January 27, 2009, with Nilesen and other individuals associated with HPI being formally charged. The charges specifically cited violations of 33 U.S.C. §1319(c)(2)(B) of the Clean Water Act, which prohibits the knowing introduction of pollutants or hazardous substances into sewer systems, and 42 U.S.C. §6928(d)(2)(A) of the Resource Conservation and Recovery Act, covering knowing RCRA violations. The EPA’s investigation uncovered a deliberate attempt to circumvent environmental regulations and cut costs at the expense of public safety.

The case unfolded with a series of guilty pleas and subsequent sentencing. On June 12, 2009, Nilesen himself pled guilty to violations of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and was ordered to pay a criminal penalty, the amount of which was not disclosed in available records. A co-defendant, Garvey, entered a guilty plea on September 1, 2009, receiving a twelve-month prison sentence and a hefty $100,000 federal fine. Finally, on March 23, 2010, HPI, as a corporate entity, also pled guilty to one count of violating RCRA, resulting in a $300,000 federal fine.

While the financial penalties and jail time represent a measure of accountability, environmental advocates have long argued that such punishments are often insufficient to deter similar offenses. The case of HPI serves as a stark reminder of the ongoing challenges faced by environmental regulators in combating illegal waste disposal practices and holding polluters responsible for their actions. The full extent of the environmental damage caused by HPI’s actions remains a concern for local residents and environmental groups.
