Dear NPDES Permit Holder:

This letter initiates the 2023 Discharge Monitoring Report - Quality Assurance (DMR-QA) Study 43. By receipt of this letter, you are required under Clean Water Act (CWA) Section 308 to participate in DMR-QA Study 43 unless your facility is covered by an EPA waiver.^* Your participation plays a key role in monitoring the quality of data used to assure the integrity of the CWA’s National Pollutant Discharge Elimination System (NPDES) Program and assures your ability to maintain compliance with NPDES permit requirements and conditions.

DMR-QA Study 43 covers major and select minor NPDES permit holders. You (the permittee) are responsible for ensuring that results of DMR-QA Study 43 tests, performed by your in-house and/or contract laboratories, are graded by an accredited Proficiency Testing (PT) Provider. If any graded test results are “Not Acceptable”, you must follow up with the laboratory to determine the cause of the deficiency and ensure corrective action is taken to prevent future occurrences. While performing tests and analyses, please ensure that your test methods/procedures follow 40 CFR part 136 regulations and applicable guidance. Use the same personnel and equipment as you would for routine NPDES permit compliance monitoring tests.

Recent Changes or Clarifications

• Arkansas DMR-QA participants that report their results to Arkansas’ DMR-QA Coordinator can now submit their DMR-QA Permittee Data Report package through Arkansas DEQ’s e-portal, https://eportal.adeq.state.ar.us/.

• Some language previously contained within the certification statement are now presented as Yes/No questions that must be answered by the person signing the Permittee Data Report Form. EPA will not accept submitted forms that do not answer all five questions immediately above the certification statement on Page 13.

DMR-QA Study 43 – Frequently Asked Questions

Am I required to participate in this Discharge Monitoring Report - Quality Assurance (DMR-QA) Study?

NPDES major and select minor permit holders are required to participate in the DMR-QA studies. Be sure to verify the NPDES 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 10-11). 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.^{†, ‡, §}

What is the purpose of this DMR-QA Study?

The purpose of DMR-QA Study 43 is to ensure the integrity of data submitted by the permittee for DMR reporting requirements and evaluate performance of the laboratories to analyze wastewater samples.

What laboratory tests are required under DMR-QA?

Permittees are responsible for having their laboratory(ies) test wastewater analytes that are both in their NPDES permit and included in Study 43. For required Whole Effluent Toxicity (WET) tests, permittees must participate even if the test conditions (e.g., temperature, time of acute test, synthetic seawater matrix, etc.) in the permit do not exactly match those in Study 43. Refer to “WET Testing Laboratory Instructions” (page 8) for more information.

How should laboratory personnel perform DMR-QA tests?

For all pollutant parameters, especially field test parameters (e.g., pH, residual chlorine), use the same personnel and equipment as required for NPDES permit compliance monitoring tests. Ensure your test methods and procedures follow 40 CFR part 136 regulations.

Where can laboratories get test samples?

Laboratories may order DMR-QA samples from a Proficiency Test (PT) Provider accredited by the American Association for Laboratory Accreditation or the ANSI National Accreditation Board. A list of accredited PT Providers is provided on page 9.

What should permittees and laboratories do first?

Permittees must first confirm receipt of this package by June 2, 2023 to their State DMR-QA Coordinator (pages 10-11) via e-mail or postal mail. Permittees must also send a copy of the enclosed instructions/checklists to all in-house and contract laboratories. The permittee specifies on the checklist which analyses the laboratory will perform. See Permittee Instructions (page 6) for more information. Upon receipt of instructions, laboratories must order samples from an accredited PT Provider (page 9). This should be done early to allow sufficient time to perform the required analyses and send ungraded test results to the PT Provider prior to the close of DMR-QA Study 43 (August 4, 2023). See Laboratory Instructions (pages 7-8) for more information.

Can I use a Water Pollution (WP) Study to satisfy DMR-QA requirements?

Yes, permittees may use a WP study to satisfy some or all the DMR-QA requirements. However, only test results from WP studies closing between January 1, 2023, and August 4, 2023, will be accepted. See Permittee Instructions for more information (Step 5 on page 6).

What steps do I take after the proficiency testing?

After laboratories report their data to the PT Providers, the PT Provider issues a report to the laboratory and the State DMR-QA Coordinator indicating the test results were “Acceptable” or “Not Acceptable”. The laboratory must then forward a copy of the graded report to the permittee. The permittee subsequently completes the checklists on pages 15-16, indicating the laboratory’s grade for each required analyte. One set of checklists must be used for each laboratory. The permittee must also fill out the NPDES Permittee Data Report Form (EPA Form 6400-01, pages 12-13) and submit a signed copy with the completed checklists and copies of the laboratory’s graded reports to the State DMR-QA Coordinator by September 29, 2023.

What do I do if a laboratory receives a “Not Acceptable” test result?

If any graded test results are “Not Acceptable”, the permittee must follow up with the laboratory to determine the cause of that test result and take corrective action to prevent future occurrences. The laboratory must order retesting samples, analyze them, and write a corrective action response for the permittee. The permittee then submits retest results and a corrective action report to the State DMR-QA Coordinator by November 9, 2023. Note: If the laboratory requires a retest to satisfy the corrective action, the laboratory must use a WP study or a quick turnaround PT sample. Data must be reported to the PT Provider by the PT Provider’s published closing date or by October 27, 2023, whichever is earlier.

Can I submit my Permittee Data Report Form electronically?

States may accept scanned, signed copies of the DMR-QA Permittee Data Report package by way of e-mail. Some states such as Arkansas now offer electronic reporting of their DMR-QA Permittee Data Report package. States listed on pages 10 and 11 that are marked with a dagger-style footnote (†) offer their own electronic form of the Study 43 Data Report package.

Where do I go for more information?

DMR-QA resources including fill-and-print forms are available at https://www.epa.gov/compliance/discharge-monitoring-report-quality-assurance-study-program.

NPDES Permittee Instructions

1. Verify that your participation in DMR-QA Study 43 is required by confirming the NPDES permit number on the front of this package or in the e-mail announcement sent to you. If you believe you received this study in error or have questions about your exemption status, contact your State DMR-QA Coordinator (pages 10-11). Please refer to Footnotes 2, 3, and 4 of the Frequently Asked Questions page (page 5) for a list of exempted states.

2. Follow the instructions on the DMR-QA Study 43 Important Notice (inside front cover of study package) and immediately confirm receipt of this package to your State DMR-QA Coordinator via postal mail or e-mail. You must submit your response no later than June 2, 2023. If your permit is inactive, please contact your State DMR-QA Coordinator immediately.

3. Send copies of these instructions to each contract and in-house laboratory, if applicable. Ensure DMR-QA samples are analyzed by the same laboratories that routinely perform analyses for your Discharge Monitoring Report (DMR) requirements. Indicate which tests the laboratory will perform by checking the appropriate boxes in the “Test Required” column in the enclosed tables (pages 15-16).

4. Ensure that each laboratory uses their U.S. EPA Laboratory Code on all reported test results. Make certain your laboratories understand and complete all requirements. Laboratories needing a new U.S. EPA Lab Code or wanting to confirm their existing U.S. EPA Lab Code, should contact their EPA Regional DMR-QA Coordinator listed on page 9. Submit all requests for lab codes at least one week before the DMR-QA Study 43 end date (August 4, 2023) or one week prior to the PT Provider’s WP study due date to allow time for response.

5. Instruct your laboratory to order samples for analytes that are both in your permit and included in DMR-QA Study 43. Your in-house and contract laboratories must order PT samples from an accredited PT Provider (page 9). Ensure your laboratory orders the samples early enough to allow time to perform the required analyses and send test results to the PT Provider prior to the close of DMR-QA Study 43 (August 4, 2023). Your laboratory should register your permit number with the PT Provider prior to August 4, 2023. Note: If your in-house or contract laboratory chooses to use a WP study to satisfy DMR-QA requirements, please inform the laboratory that all data must be reported to the PT Provider by the published WP study close date, even if it is prior to the DMR-QA deadline of August 4, 2023. WP studies are only valid for DMR-QA Study 43 if the WP study meets the following requirements:

   1. Samples are offered by an accredited PT Provider (page 9).

   2. The WP study closed between January 1, 2023, and August 4, 2023.

   3. The PT Provider shows the WP test results from each of the permittee’s regulated analytes on the DMR-QA reporting form.

6. Permittees are responsible for ensuring that laboratories submit data on the permittee’s behalf to the PT Provider by the end of DMR-QA Study 43 (August 4, 2023). Laboratories must send ungraded data to the same PT Provider that provided the samples to the laboratory. By September 1, 2023, PT Provider-graded test results will be sent back to the laboratories. Permittees will not receive graded reports directly from PT Providers unless they are an in-house laboratory. Note: Permittees are not required to report ungraded data to the PT Provider on their laboratories’ behalf nor should permittees send ungraded data to their State DMR-QA Coordinator.

7. Permittees must require laboratories to forward the PT Provider-graded test results to them by September 15, 2023. Using these graded test results, permittees must fill out the Chemistry/Microbiology Analyte and WET Analyte checklists (pages 15-16) for each laboratory, indicating the analyte tests performed by the laboratory and whether the test result was “Acceptable” or “Not Acceptable”. Make sure the appropriate NPDES permit number and U.S. EPA Lab Code are on each checklist. If you use more than one laboratory, you must use a separate checklist for each laboratory. If a laboratory reports more than one test method to you for any single analyte, you must use a separate checklist for each test method reported.

8. Follow the directions on the “NPDES Permittee Data Report Form” (Form 6400-01, pages 12-14) and complete the information. You may use a “fill and print” form available at: https://www.epa.gov/compliance/discharge-monitoring-report-quality-assurance-study-program. By September 29, 2023, you must send a copy of the signed Form 6400-01, graded test results, and completed checklists from step 7 for each of your permits to the State DMR-QA Coordinator.

   1. However, if you (the Permittee) have verified that the PT Provider’s graded test results have been transmitted to the State DMR-QA Coordinator, you are only required to submit the signed Form 6400-01 and the applicable checklists to the State DMR-QA Coordinator. In this situation, the laboratory should provide a list of its permittees’ NPDES permit numbers associated with each required analyte to the PT Provider prior to the close of DMR-QA Study 43 or the WP study. Check with your laboratory to determine whether the PT Provider is sending the graded data directly to the State DMR-QA Coordinator.

   2. Permittees must maintain a copy of the completed NPDES Permittee Data Report Form, checklists, and graded laboratory results as a record for at least three (3) years.

9. After receiving the PT Provider-graded test results, permittees must consult with the laboratory and investigate all test results graded by the PT Provider as “Not Acceptable”. Permittees must identify and report to the State DMR-QA Coordinator the causes of any discrepancies and must describe the analytical system changes required to correct the discrepancies. If the laboratory requires a retest to satisfy the corrective action, the laboratory must use a WP study or a quick turnaround PT sample. Data must be reported to the PT Provider by the PT Provider’s published closing date or by October 27, 2023, whichever is earlier. Laboratories must order retesting samples by September 15, 2023, for any “Not Acceptable” results and perform the retests as soon as possible. The corrective action report should include results from any retest/verification analysis performed and must be sent to the State DMR-QA Coordinator on or before November 9, 2023.

Chemistry/Microbiology Laboratory Instructions

Your laboratory is designated to participate in DMR-QA Study 43 by a NPDES permittee because the permittee uses or plans to use your laboratory to perform chemistry/microbiology analyses to satisfy their NPDES permit requirements during 2023. For measurements of all pollutant parameters, especially field test parameters (pH, residual chlorine, etc.), use the same personnel and equipment as required for NPDES compliance monitoring analyses. Please ensure that your test methods/procedures follow 40 CFR part 136 regulations. Please note that for low level mercury, the concentration range is 20 - 100 ng/L (20 - 100 parts per trillion) and for low level total residual chlorine, the concentration range is 75 - 250 µg/L (75 - 250 parts per billion). If you have questions about whether you should perform the test using the normal or the low-level mercury and/or low-level total residual chlorine concentration, contact your State DMR-QA Coordinator.

1. Each permittee for whom you analyze or provide data in 2023 will determine which analyses you must perform by checking the appropriate boxes on the enclosed “Chemistry/Microbiology Analyte Checklist” (page 15).

2. Order DMR-QA Study 43 chemistry and microbiology samples from one of the Proficiency Test (PT) Providers (page 9). Be sure to allow yourself enough time to perform the analyses before the closing date of DMR-QA Study 43 (August 4, 2023). Maintain a copy of all completed order forms for your records.

Note: You may be able to utilize the test results from a Water Pollution (WP) study to meet the requirements of DMR-QA Study 43, if all the following conditions are met:

1. Samples are offered by an accredited PT Provider (page 9).

2. The WP study closes between January 1, 2023, and August 4, 2023.

3. The PT Provider shows the WP study results of each permittee’s regulated analytes on the DMR-QA reporting form.

3. Each reported value must be produced from a single analytical run using the analytical system that routinely performs these analyses to produce compliance monitoring data required under your permittee’s NPDES permit. Your results must not be compared with results from other independent analyses conducted by you or any other laboratory before reporting your test results to the PT Provider.

4. Record your ungraded analytical data and your EPA Lab Code on the Data Reporting Forms that you received with your test samples. Be sure to follow the PT Provider’s instructions and deadlines that you received with these samples.

5. You are required to use the EPA-assigned Lab Code on all reported test results. If you need a new EPA Lab Code or need to verify your existing EPA Lab Code, please contact your EPA Regional DMR-QA Coordinator (see contact information on page 9).

6. Send the data requested by each of your permittees to the PT Provider for grading. You must send data to the same PT Provider that sent you the test samples. Make sure you provide the DMR-QA Study 43 or WP study results to the PT Provider by August 4, 2023. If you choose to use a WP study, you must report all data to the PT Provider by the PT Provider’s published WP study close date, even if it is prior to the DMR-QA deadline of August 4, 2023. Notify the PT Provider that the WP study is being used to satisfy DMR-QA Study 43 requirements and send them copies of the analyte checklist(s) if you are reporting via hard copy.

7. The PT Provider will grade your analyses and send the graded test results to you by September 1, 2023. If the PT Provider is submitting graded test results sorted by permit number to the State DMR-QA Coordinator, then you should register your permittees’ permit numbers associated with each required analyte with the PT Provider prior to the close of DMR-QA Study 43 or the WP study. Forward the graded test results of the analytes to the permittee by September 15, 2023, so the permittee can fill out the analyte checklist on page 15.

8. If any graded test results are “Not Acceptable”, laboratories should coordinate with the permittee to determine the cause of that test result and identify corrective action to prevent future occurrences. If the laboratory requires a retest to satisfy the corrective action, the laboratory must use a WP study or a quick-turnaround PT sample. Data must be reported to the PT Provider by the PT Provider’s published closing date or by October 27, 2023, whichever is earlier. Laboratories must order retest samples for “Not Acceptable” analyte test results by September 15, 2023. The corrective action report and graded retest results must be forwarded to the permittee as soon as possible, for the permittee is required to submit a completed corrective action report to their state DMR-QA coordinator by November 9, 2023.

WET Testing Laboratory Instructions

Your laboratory is designated to participate in DMR-QA Study 43 by a NPDES permittee because the permittee uses or plans to use your laboratory to perform Whole Effluent Toxicity (WET) analyses during 2023. For all analytes, use the same personnel and equipment as required for NPDES permit compliance monitoring analyses. Labs should ensure that WET test methods/procedures follow instructions from your PT Provider and EPA’s WET test manuals referenced below, which include both EPA’s promulgated WET test methods at 40 CFR part 136 and EPA’s recommended short-term chronic marine West Coast WET test methods (1995).

1. The permittee(s) determine which analyses you will perform by checking the appropriate boxes on the enclosed WET Analyte checklist (page 16). Labs should ensure that the permittee has selected the test organism(s), test conditions, and testing requirements that most closely resemble those required by the permit for which you are supplying test results. Use the guidelines immediately below and the table on page 16 to select the proper WET tests.

   Guidelines for Choosing the Correct WET Test Organism/Conditions/Test Endpoint(s):

   • Laboratories should only report one test endpoint for each DMR-QA WET test code required.

   • For laboratory performance quality assurance purposes only, the point estimation techniques that produce test endpoints such as the Inhibiting Concentration 25% (IC25) are the preferred statistical approach used for calculating test endpoints for effluent chronic toxicity tests. However, laboratories should choose the statistical approach that allows calculation of the test endpoint(s) required by the NPDES permit and are used for routine permit compliance tests. For example, if the permit specifies a No Observable Effect Concentration (NOEC) test endpoint for Survival and it is reported regularly on DMRs, this test endpoint may be reported for DMR-QA.

   • If the permit requires WET testing with the Fathead minnow (Pimephales promelas), Ceriodaphnia dubia, Daphnia magna, Daphnia pulex, Americamysis bahia (Mysidopsis bahia), Inland silverside (Menidia beryllina) or Sheepshead minnow (Cyprinodon variegatus), the laboratory must test with those test organisms listed in each permit using the test conditions, including temperature, defined in the WET Test Codes.

   • If the permit’s WET testing conditions for Ceriodaphnia dubia specify 48-hr acute static renewal testing, then conduct this test using the static non-renewal conditions specified in WET Test Codes 19 and 20.

   • If the permit’s WET testing conditions for Daphnia magna and Daphnia pulex specify 48-hr acute static renewal testing, then conduct this test using the static non-renewal conditions specified in WET Test Codes 32 and 38.

   • If the permit’s WET testing conditions require 24-, 48-, or 96-hr acute testing using any of the test organisms included in Study 43, use the 48-hr acute test conditions specified in the WET Test Codes.

   • If the permit requires 20°C acute testing for any test organisms included in Study 43, use 25°C acute test conditions specified in the WET Test Codes.

2. Order DMR-QA toxicity samples from an accredited PT Provider (page 9). Allow yourself enough time to perform the analyses before the closing date of DMR-QA Study 43 (August 4, 2023). Maintain a copy of all completed order forms for your records.

3. Each reported value must be produced from a single analytical run using the analytical system that routinely performs these analyses to produce compliance monitoring data required under your permittee’s NPDES permit. Your results must not be compared with results from other independent analyses conducted by you or any other laboratory before reporting your test results to the PT Provider.

4. Record your ungraded analytical data and EPA Lab Code on the Data Report Form received with your samples. Be sure to follow the PT Provider’s instructions and deadlines that you received with the samples. You must use the EPA-assigned Lab Code on all reported test results. If you need a new EPA Lab Code or need to verify your current code, contact your EPA Regional DMR-QA Coordinator (page 9).

5. Send the ungraded data requested by each of your permittees to the PT Provider for grading. You must send it to the same PT Provider that sent you the test samples. Make sure you provide the DMR-QA Study 43 study results by August 4, 2023.

6. The PT Provider will grade your test results and send them to you by September 1, 2023. If the PT Provider is submitting graded test results sorted by permit number to the State DMR-QA Coordinator, then you should register your permittees’ permit numbers associated with each required analyte with the PT Provider prior to the close of DMR-QA Study 43 or the WP study. Forward the graded test results of the analytes to the permittee by September 15, 2023, so the permittee can fill out the analyte checklist on page 16.

7. If any graded test results are “Not Acceptable”, laboratories should coordinate with the permittee to determine the cause of the result and identify corrective action to prevent future occurrences. If the laboratory requires a retest to satisfy the corrective action, the laboratory must use a WP study or a quick turnaround PT sample. Data must be reported to the PT Provider by their published closing date or by October 27, 2023, whichever is earlier. Laboratories must order retest samples for “Not Acceptable” analyte test results by September 15, 2023. The corrective action report and graded retest results must be forwarded to the permittee as soon as possible, for the permittee is required to submit a completed corrective action report to their state DMR-QA coordinator by November 9, 2023.

	United States Environmental Protection Agency Office of Enforcement and Compliance Assurance DMR-QA Study 43 (This data is collected under the authority of Section 308 of the Clean Water Act.)																OMB Control No. 2080-0021 Approval expires xx/xx/xxxx
																	2 023
Instructions for the NPDES Permittee Data Report Form: This is a two-page form. All fields on page 13 are required to be reported except for those explicitly marked as optional. Enter your NPDES permit number at the top of pages 13 and 14. You must fill in the 2-digit permit extension field at the top of page 13 if there is an extension for your permit code. If you have one, the extension will appear next to your permit code in the address box on page 13; for example: “NPDES Permittee CT1234567-01”. If there is no extension, leave this field blank. Identify each of your laboratories on page 14, including their U.S. EPA Lab Code which is a unique identifier number assigned by EPA. (Refer to page 6, item 4 in the Study 43 package) (NOTE: The U.S. EPA Lab Code of the laboratory that produced the data must also appear at the top of the Chemistry/ Microbiology and WET analyte checklists on pages 15-16.) Make copies of pages 13 and 14. Attach a copy of these pages to the Chemistry/Microbiology and WET analyte checklists. Separate copies of each checklist must be filled out for each laboratory you used. Also, if a laboratory reports more than one test method to you for any single analyte, you must use a separate checklist for each test method reported. These checklists must indicate the graded test results for the analytes tested by the laboratory that are in your permit and required for DMR-QA (Acceptable or Not Acceptable). For Study 43, it is optional but encouraged to write in the approved EPA test method used for DMR- QA Chemistry/Microbiology analytes. If you use a state-certified laboratory to generate your NPDES data in a state that has been granted a partial exemption from the DMR-QA study by the EPA Region, check the “Analyte determined by state-certified laboratory” box(es) on the checklists (pages 15 and 16) for all analytes in your permit analyzed by a state-certified laboratory. Sign and date the certification statement on page 13 and the applicable checklists on pages 15 and 16. Forms that do not have a signed certification statement by the permit holder or authorized representative will be considered invalid. Make copies of the NPDES Permittee Data Report form and checklists for your records. Submit the signed copy of the Permittee Data Packages by e-mail or postal mail to the State DMR-QA Coordinator no later than September 29, 2023.
Paperwork Reduction Act Burden Statement. This collection of information is approved by OMB under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. (OMB Control No. 2080-0021). Responses to this collection of information are mandatory for Major and select Minor NPDES permit holders under Clean Water Act section 308 [33 U.S.C. § 1318]. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The public reporting and recordkeeping burden for this collection of information is estimated to average 6.6 hours per response. Send comments on the Agency’s need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden to the Regulatory Support Division Director, U.S. Environmental Protection Agency (2821T), 1200 Pennsylvania Ave NW, Washington, DC 20460. Include the OMB control number in any correspondence. Do not send the completed form to this address.
