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 more information on the types of errors identified, see EPA's Technical Support Document for the 2010 Effluent Guidelines Program (PDF) (255 pp, 3.4MB). Because of this review, and EPA's methodology for interpreting data and calculating loads (explained in EPA's Technical Support Document for the Annual Review of Existing Effluent Guidelines and Identification of Potential New Point Source Categories), the calculated loads and category rankings may differ using DMR and TRI data that has not been updated. Data that have been updated by EPA's annual reviews are flagged by green flags designating that a change has been made to a concentration, quantity, or flow value. View a listing of the changes for the most recent annual review (PDF) (1 p, 7K).
