According to the DNR, Nor-Am Cold Storage has been fined $17,000 for causing two fish kills.
Based out of Le Mars, the company has polluted a creek nearby with ammonia-laden water. This has occurred twice in the past four years.

The leaks occurred when the refrigeration units on the company’s rooftop were serviced. While performing the tasks, anhydrous ammonia was used as a refrigerant. The ammonia-laden water leaked from a bucket and made its way to a city storm sewer.

The first contamination was discovered in May 2018 when citizens nearby could smell ammonia. The DNR reported that over 20 pounds of ammonia ran into the creek and sewer. The next day, about 50 dead, small fish were reported. Nor-Am spent hours pumping the water out of the creek to prevent the contamination from reaching the Floyd River. The company then agreed to pay a $7,000 fine.

Another fish kill in Le Mars was reported in September 2021. DNR environmental specialist Jacob Simonsen said there were around 20 dead fish near the creek. Soon after, Nor-Am reported that another ammonia leak had occurred just three days before. This time, around four pounds of ammonia had been leaked. The company must report any possible leaks to the DNR but failed to do so due to an unknown reason. However, the company agreed to pay a fine of $10,000 for the leak and is believed to write a plan to the DNR in hopes of stopping future pollution.
