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. 

 Data Dictionary

Data fields included on the DMR Non-Receipt Violations page are described below. 

 Permit Feature Number
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.
 Monitoring Location
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

 Limit Set Name
The name associated with a group of parameter permit limits.
The unique code and text description identifying the parameter being reported on the DMR.
 Value Type
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
 Statistical Base Monthly Average
Indicates whether the statistical base applicable to the permit limit and DMR values is a Monthly Average, Non-monthly Average, or Neither. 
 Monitoring Period End Date
The date that the monitoring period for the values covered by the DMR ends.
 DMR Due Date
The due date for the DMR to the NPDES program authority (e.g., EPA or state environmental agency). 
 NPDES Violation ID
The system-generated unique identifier for the NPDES Violation.
 RNC Detection Date
The date associated with the Reportable Noncompliance (RNC).
 RNC Detection Description
Indicates the type of reportable noncompliance (RNC) for a particular violation event.
 RNC Resolution Date
The date RNC was marked to its current resolution status. It can be resolved manually or automatically.
 RNC Resolution Description
Indicates how the RNC was resolved for a particular violation. For outstanding DMR Non-Receipt Violations, the description will be "NC - Unresolved RNC."
 NODI Code and Description
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.
 NODI Validation Flag
Indicates whether the NODI code is considered valid (Y) or invalid (N) for compliance determination purposes.
 DMR Submission Days Late
The system-generated number of days the DMR value is late.
 DMR Received Date
The date the DMR was received by the NPDES program authority. 
 Violation Code
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
