U.S. Gov't Agencies - EPA: Discharge Monitoring Report (DMR) Pollutant Loading Tool
The Discharge Monitoring Report (DMR) Pollutant Loading Tool is a new tool designed to help you determine who is discharging, what pollutants they are discharging and how much, and where they are discharging. The tool calculates pollutant loadings from permit and DMR data from EPA‘s Permit Compliance System (PCS) and Integrated Compliance Information System for the National Pollutant Discharge Elimination System (ICIS-NPDES). Data is available for the years 2007 through 2010.
