Discharge Monitoring Report (DMR) Non-Receipt Violations Help
The Detailed Facility Report (DFR) Three-Year Compliance History table displays the number of CWA D80/D90 violations that occurred during a particular quarter or month for the NPDES permit, if applicable, regardless of resolution status. These violation counts are hyperlinked to a drilldown page with more information about each D80/D90 violation. This page describes the data elements that are presented in the Discharge Monitoring Report (DMR) Non-Receipt Violations table drilldowns.
EPA's Clean Water Act (CWA) National Pollutant Discharge Elimination System (NPDES) data system of record, Integrated Compliance Information System (ICIS) for NPDES data, automatically generates DMR non-receipt violations for all permittees (majors and non-majors). DMR values not received within 31 days of the DMR form due date result in the generation of a violation code (D80 or D90). ICIS-NPDES identifies these DMR non-receipt violations and automatically creates violation codes for the missing DMR values with monitoring requirements (D80) and missing DMR values with effluent limits (D90). EPA's data sharing policy allows states a 40-day window to report DMR values to EPA's data system; therefore, DMR values reported on time to state agencies and shared with EPA within 40 days do not contribute to permit level noncompliance status.
All data are from the EPA's program system, ICIS-NPDES. Read About the Data for more information on the data sources and when the data were last updated in ECHO.

The 3-digit code representing the permitted outfall or pipe of interest in ICIS-NPDES (e.g., 001). This is the identifier assigned for each location at which permit conditions are being applied.
Describes the location at which the monitoring requirement (and numeric effluent limit, if limited) applies. One parameter may have several monitoring location requirements pertaining to the same permitted feature. Valid code values/descriptions are:
| Code | Description |
|---|---|
| 0 | Intake |
| 1 | Effluent Gross |
| 2 | Effluent Net |
| 3 | Intake Public Water |
| 4 | Pretreatment, Process Complete |
| 5 | Upstream Monitoring |
| 6 | Downstream Monitoring |
| 7 | Intake from Stream |
| 8 | Other Treatment, Process Complete |
| 9 | Phosphate Removal, Process Complete |
| A | Disinfection, Process Complete |
| AP | Alternate Process |
| B | Prior to Disinfection |
| C | Nitrogen, Removal Complete |
| D | Tertiary/Advanced Process Complete |
| E | Secondary/Biological Process Complete |
| EG | Effluent Gross |
| F | Primary/Preliminary Process Complete |
| G | Raw Sewage Influent |
| H | During Manufacturing |
| I | Intake from Well |
| IN | Allowed Increase |

The name associated with a group of parameter permit limits.
The unique code and text description identifying the parameter being reported on the DMR.
The indication of the limit value type (e.g., Quantity 1, Concentration 2). Valid code values are:
| Code | Description |
|---|---|
| Q1 | Quantity 1 |
| Q2 | Quantity 2 |
| C1 | Concentration 1 |
| C2 | Concentration 2 |
| C3 | Concentration 3 |
Indicates whether the statistical base applicable to the permit limit and DMR values is a Monthly Average, Non-monthly Average, or Neither.
The date that the monitoring period for the values covered by the DMR ends.
The due date for the DMR to the NPDES program authority (e.g., EPA or state environmental agency).
The system-generated unique identifier for the NPDES Violation.
The date associated with the Reportable Noncompliance (RNC).
Indicates the type of reportable noncompliance (RNC) for a particular violation event.
The date RNC was marked to its current resolution status. It can be resolved manually or automatically.
Indicates how the RNC was resolved for a particular violation. For outstanding DMR Non-Receipt Violations, the description will be "NC - Unresolved RNC."
The no data indicator (NODI) code indicates the reason that data for an expected DMR value were not submitted by the permittee for a monitoring period end date.
Indicates whether the NODI code is considered valid (Y) or invalid (N) for compliance determination purposes.
The system-generated number of days the DMR value is late.
The date the DMR was received by the NPDES program authority.
Violation code describing both automatically and manually detected violations.
Code Type/Description D80 DMR Non-Receipt - Required monitoring DMR value overdue D90 DMR Non-Receipt - Limited value overdue
