What is the purpose of a Discharge Monitoring Report (DMR) in NPDES programs?

Discharge Monitoring Reports are the formal record that a facility under the NPDES program uses to show what it actually discharged and whether that discharge stayed within the permit limits. They summarize monitoring data—like pollutant concentrations and flow—for the reporting period and indicate if any limits were exceeded. Regulators rely on these reports to track compliance over time, to assess potential impacts on water quality, and to identify violations or tendencies that might affect permit decisions. While spills or unusual events require additional reporting, a DMR specifically documents routine monitoring results and permit compliance, not tax details or grant applications.
