The Discharge Monitoring Report (DMR) Pollutant Loading Tool is a new tool that was created by the EPA as an easy way to monitor the pollutants that are released into the U.S. waterways. This tool is 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.
You may search using the DMR Pollutant Loading Tool for “top ten” lists to help easily identify facilities and industries that are discharging the most pollution and to identify the most highly impacted waterways. When discharges are above permitted levels, you can view the violations and link to details about enforcement actions that EPA and states have taken to address these violations.
