Discharge Monitoring Report (DMR) Pollutant Loading Tool

Note: This area of the DMR Loading Tool includes data used for EPA's annual review of industrial effluent discharges. EPA's Office of Water is responsible for developing programs and tools authorized under the Clean Water Act (CWA), which enables EPA and the states to protect and restore the Nation's waters. The CWA requires EPA to annually review and, if appropriate, revise its water pollution control technology-based regulations, called "effluent limitations guidelines" or "effluent guidelines" that limit the discharge of pollutants to waters of the U.S. from industrial facilities. As part of the EPA's annual reviews, EPA estimates the load of pollutants discharged using a combination of discharge monitoring report (DMR) data, from ICIS-NPDES, and Toxics Release Inventory (TRI) data. EPA also assigns a relative toxic weight to the estimated loads to rank industrial categories by toxic weighted pound equivalents (TWPE). For more background on EPA's effluent guidelines program see EPA's Effluent Guidelines website.

EPA reviews the DMR and TRI data used to calculate effluent loads and TWPE for accuracy prior to further investigating industrial categories for possible effluent guideline revisions. For identified outlier data, EPA contacts states and facilities to confirm and update (if appropriate) data values and units. For information on the methodology and types of changes identified, see EPA's most recent odd-numbered year Annual Effluent Guidelines Review Report (PDF) (169 pp, 2MB) on the Effluent Guidelines Plan webpage. Because of this review and EPA's methodology for interpreting data and calculating loads, the calculated loads and category rankings may differ from original calculations using DMR and TRI data that have not been updated. Data that have been updated by EPA's annual reviews are indicated by green flags designating that a change has been made to a concentration, quantity, or flow value. A listing of the DMR and TRI data changes from the most recent annual review is available in the Annual Effluent Guidelines Review Report Appendices (PDF) (241 pp, 3.3MB).
