Division Programs

  • Discharge Monitoring Report – Quality Assurance (DMR-QA)
  • ​DMR-QA is a proficiency testing (PT) program provided by U.S. EPA for wastewater laboratories in Ohio. The DMR-QA coordinator is Steve Roberts. 
  • Acceptable Corrective Action Procedures
    • For "Not Acceptable" results, the permittee must follow up with the laboratory to determine the cause of the deficiency and ensure corrective action is taken to prevent future occurrences.
    • The laboratory must order a new PT for the failed analyte(s), using either another PT study or a fast turnaround study from an approved PT provider, and write a corrective action report for the permittee.
    • The permittee is required to submit a completed and signed corrective action report (Word) (PDF) to the DMR-QA Coordinator.
