ANNOUNCEMENTMemorandum (PDF) (1 pg, 460K) detailng extension of deadline for submitting Study 33 Address Verification Form to April 5, 2013
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 routinely 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.
Study 33, mailed in Feburary 2013, includes chemistry, microbiology and Whole Effluent Toxicity (WET) tests.
All proficiency test samples are supplied by the American Association for Laboratory Accreditation (A2LA) proficiency testing providers.
You must acknowledge receipt of the study package by submitting verification of your address via e-mail or postal mail to your state DMR-QA coordinator. Carefully follow the instructions and format for an e-mail response or use the included form to send a written verification. Use only one option to submit your response.
EPA approves certain state laboratory certification programs to be used as either a full or a partial substitute for DMR-QA. Check with your state or regional coordinator if you have questions about your state's exemption status.
As of January 1, 2013, states exempt from DMR-QA by an EPA-approved full waiver include:
- New Jersey
- North Carolina
- South Carolina
- West Virginia
As of January 1, 2012, states partially exempt from DMR-QA by an EPA-approved partial waiver include:
- Kansas—permittees that utilize only commercial laboratories are exempt
- Louisiana—permittees that utilize only commercial laboratories are exempt
- Oklahoma—NPDES permittees that currently participate in Oklahoma’s laboratory accreditation program are exempt
