Former National Compliance Initiative: Keeping Industrial Pollutants Out of the Nation’s Waters

Industrial Wastewater Discharge
Industrial Wastewater Discharge

In FY 2019, EPA modified this NCI to address significant noncompliance by all individually permitted NPDES permittees. See National Compliance Initiative: Reducing Significant Non-Compliance with National Pollutant Discharge Elimination System (NPDES) Permits for more information on this new NCI.


Far too many of our lakes, rivers and streams have water quality impairments, which can threaten drinking water sources and impact how much surrounding communities are able to use and enjoy them. The pollutants most often responsible for these impairments are nutrients, metals, and those that cause organic enrichment/oxygen depletion. 


The objective of this initiative is to improve surface water quality and reduce potential impacts on drinking water by assuring that NPDES permittees are complying with their permits. 


The following map and chart show EPA’s actions in targeting and reducing illegal discharges to water by industrial polluters.
