Water Pollutant Loading Tool Modernization
Last Updated: December 12, 2017
The Water Pollutant Loading Tool (Loading Tool) is a public access website designed to help you determine who is discharging, what pollutants they are discharging and how much, and where they are discharging. The Loading Tool calculates pollutant loadings from permit and DMR data from EPA's Integrated Compliance Information System for the National Pollutant Discharge Elimination System (ICIS-NPDES). Data are available from the year 2007 to the present.
The Loading Tool is being transitioned into ECHO to increase user access to data and streamline site maintenance.
EPA plans to retire the legacy site (https://cfpub.epa.gov/dmr/) in December 2017.
