(Estherville)--A rendering plant south of Estherville has entered into a consent order with the Iowa Department of Natural Resources for repeated discharge violations of its wastewater treatment agreement with the city of Estherville. 

The order requires Central Bi-Products to pay a $10,000 administrative penalty. The DNR says within 30 days of the Order’s effective date, Central Bi-Products shall either decide to comply with the terms of the treatment agreement, or negotiate higher treatment agreement limits with the City of Estherville. If the Central Bi-Products facility requires pretreatment upgrades, then Central Bi-Products must submit a construction schedule for approval.

The order also says within 90 days, Central Bi-Products will provide the DNR with the conclusions reached by the professional engineer investigating the source of the discharge. Central Bi-Products will also include a schedule for correcting any deficiencies.
