Stormwater Resources for Construction ProjectsIowa DNR is the delegated administer to the NPDES (National Pollutant Discharge Elimination System) program for the State of Iowa by the authority of the the EPA. To find more information on the NPDES General Permit, the Iowa DNR Storm Water Program web page provides key links to answer questions and direct developers to the Online Storm Water General Permit Application.
To determine if a construction project requires a Storm Water Discharge Permit, Iowa DNR provides a list of three general classes of activities that must be covered. These are:
- Construction activity that disturbs one or more acres or is part of a larger project that disturbs one or more acres in total.
- Certain types of industrial or commercial activities.
- Many city storm sewer systems in larger communities or those near larger communities.
As part of the NPDS permit, a Storm Water Pollution Prevention Plan (SWPPP) is required for construction projects. The Iowa Storm Water Education Partnership (ISWEP) provides an excellent SWPPP resource web page for businesses seeking guidance on developing a SWPPP.
