Discharge Monitoring Report-Quality Assurance Study Program

CWA Topics

Extension of Deadline 

Due to delays in printing and mailing some packages for the Discharge Monitoring Report - Quality Assurance (DMR-QA) Study 34, we are extending the deadline for participants to acknowledge receipt of the Study and submit the NPDES Permittee Address Verification Form to DMR-QA State Coordinators. The new deadline is April 4, 2014.

About 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 are required to participate in DMR-QA, you must report results for the analytes listed in your permit provided that they also are 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. You may voluntarily report additional study analytes that are not listed in your permit.
