Note: The tool uses discharge monitoring report (DMR) data from ICIS-NPDES to calculate pollutant discharge amounts. EPA has verified the accuracy of the tool’s calculations. EPA has also performed a limited review of the underlying data that has focused on facilities with the largest amounts of pollutant discharges. Due to the large amount of DMR data, additional errors exist in ICIS-NPDES. Please see the User Guide(29 pp, 2.6MB), Frequently Asked Questions and Answers, and Error Correction page for instructions on how to use the tool and how to correct errors in ICIS-NPDES. The tool also uses wastewater pollutant discharge data from the Toxics Release Inventory (TRI). You can send an email to firstname.lastname@example.org with any comments or questions about the tool. You can sign up for our e-mail news bulletin and be notified when new data, enhancements, or training materials are available.
EZ Search (DMR)
Instructions. This EZ Search provides quick access to discharge monitoring data based on simple searches. The boxes below provide search options to help you determine where discharges are occurring (Location or Watershed Box), what pollutants are discharged (Pollutant Box), and who the dischargers of interest are (Industry Box). Change the criteria in one or more of the boxes below and click the Search button to retrieve DMR pollutant loadings information. For more information about how to use this search feature, refer to the User Guide for the Discharge Monitoring Report (DMR) Pollutant Loading Tool (PDF)(29 pp, 2.6MB) or Frequently Asked Questions and Answers (FAQ).
