Discharge Monitoring Report – Quality Assurance Study Program:
Major and selected minor permittees under the National Pollutant Discharge Elimination System (NPDES) program are required to participate in the annual Discharge Monitoring Report – Quality Assurance (DMR-QA) study program. DMR-QA evaluates the analytical ability of the laboratories that perform self-monitoring analyses required by their NPDES permit.
If you’re required to participate in DMR-QA, you must report results for the analytes listed in your permit, provided that they are also included in the DMR-QA study analyte list. Not all of the analytes listed on your NPDES permit may be included in an individual DMR-QA study, and you may voluntarily report additional study analytes not listed in your permit.
