DMR Pollutant Loading Tool Now Available on EPA ECHO
Water Discharge Monitoring Report (DMR) Pollutant Loading Tool. You can now access it on the Enforcement and Compliance History Online (ECHO) website. The Loading Tool is designed to help users 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 and offers a variety of ways to customize searches. Pollutant loadings are presented as pounds per year and as toxic-weighted pounds per year to account for variations in toxicity among pollutants. The ECHO version of the Loading Tool has a similar look and feel as the current Loading Tool website, which will be retired in late November 2017, with some usability improvements.
