NPDES Major and select Minor permit holders are required to participate in DMR-QA studies. Be sure to verify the permit number on the front of this package or indicated in your e-mail. If you believe you received this study in error, contact your state DMR-QA coordinator (pages 6-8). Some permit holders are not required to perform the DMR-QA study because they are located in a state that has a laboratory quality assurance program approved by EPA as a substitute for DMR-QA. Return to the Main Page for a list of states with a full or partial DMR-QA waiver.
