File a wastewater DMR after an exceedance

Practice the sequence you already learned for “File a wastewater DMR after an exceedance” until the order feels automatic. Drill the 40 CFR 122.41 DMR order. An exceedance is reported in the required window, resampled as directed, and not omitted because a later sample passed.

  1. Validate the lab result.
  2. Validate the sample chain of custody.
  3. Notify the permit authority in the required oral/written window if the permit requires it.
  4. Resample as the permit directs; do not discard the original result.
  5. Enter every required value on the DMR, including the exceedance.
  6. Attach the noncompliance explanation.
  7. Submit by the due date with the authorized signature.
