Sioux-Preme admitted to violating permitted discharge limits and environmental monitoring requirements in addition to other permit violations.
In November 2012, the Iowa Department of Natural Resources (DNR) traced a fish kill in a tributary of the Floyd River to Sioux-Preme Packing, which is just south of Sioux Center, Iowa. DNR staff found elevated ammonia levels and thousands of dead fish, including game fish, for at least nine miles downstream from the plant.
The judge also ordered the company to pay $23,000 in restitution for the fish kill and the resulting DNR investigation.
