A state environmental officer caught a truck washing operation illegally disposing of diluted corn oil. This incident occurred in Mason City, Iowa, after the officer was sent there by the DNR due to looking investigating the illegal dumping of an agricultural chemical the day before. 

When the officer arrived at Brookstone Specialty Services, he saw that on top of the pollution from agricultural chemicals, the business was also illegally throwing away diluted corn oil. The company was fined $10,000 for both incidents. The company is believed to have saved $11,000 by illegally dumping the pollution instead of proper disposal. 

According to the DNR, the first incident occurred in late 2020 after there had been reports of dead fish and the smell of petroleum coming from a nearby creek. An investigation revealed that Brookstone Specialty Services accidentally allowed brown sludge caused by distilling grain from the trucks and trailers to drain into Chelsea Creek. The drainage was originally believed to have gone to the city’s sewer system. Upon further inspection, it was determined that the creek also contained livestock bedding that had been washed into it. The company hired people to come and scoop the bedding from the creek to dispose of it properly. 

The second incident happened in June of 2021. Jacob Donaghy, an environmental specialist for the DNR said, ​​“We had a complaint that they were dumping this green stuff outback.” He continued saying, “We went there and sure enough, there was green stuff out back. It was just being dumped on the soil.”

The neon green liquid was a chemical that is normally used to prevent nitrogen from leaking off of farm fields. When the container was being cleaned out, someone rinsed the residue left by the chemical and dumped out the remaining water. When Donaghy arrived to investigate the first incident, he found the neon green liquid.
