Status: In Production

data exchange description

The Integrated Compliance Information System–National Pollutant Discharge Elimination System (ICIS-NPDES) data exchange allows state, tribe and EPA regional users to provide NPDES data to EPA in an XML format, check the results, and correct common errors that may occur to their submissions. The exchange is currently in production for the DMR data family only. Other data families, such as permits, inspections and enforcement actions, will be developed in the future.
