The Iowa Department of Natural Resources and the U.S. Environmental Protection Agency (EPA) Region 7 work together to implement the federally authorized National Pollutant Discharge Elimination System (NPDES) Program within Iowa in a timely, appropriate and effective manner.  We establish priorities, negotiate program commitments and work sharing, and evaluate program performance.  

DNR and Region 7 executed this Work Plan as a means to strengthen Iowa’s implementation of the federally authorized NPDES program.  This Work Plan contains activities and commitments by DNR and Region 7 that generally span federal fiscal years (FFY) 2013-2019.
