Operators of a manufacturing plant in Corydon have agreed to a $53,547 dollar E.P.A. fine. The Environmental Protection Agency alleged that battery manufacturer East Penn failed to properly monitor and report the wastewater it discharged into the city of Cordyn’s treatment system.

The E.P.A. says the company had not applied for a pre-treatment permit from the Iowa D.N.R., which was required because it was known the wastewater contained lead. The treated wastewater from the city discharges into West Jackson Creek, which is a tributary of the Chariton River. Under a settlement agreement, East Penn has agreed to the fine and has filed for a pre-treatment permit and begun to monitor the wastewater as required.

There is a 30-day public comment period before the settlement becomes final.
