NPDES DMR Non-Receipt Status Search Help
This page contains help information for the NPDES DMR Non-Receipt Status Search and describes the data elements that are presented in the search results and drilldowns. Select the links below to jump to each section of this page:
EPA's Clean Water Act National Pollutant Discharge Elimination System (NPDES) data system of record, Integrated Compliance Information System (ICIS) for NPDES data, automatically generates Discharge Monitoring Report (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 runs a daily process to identify 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).
ICIS-NPDES uses these DMR non-receipt violation codes (D80 or D90) to generate “reportable noncompliance (RNC) detection” codes [e.g., non-monthly average DMR value was 30 days overdue (= “K”), DMR monthly average value was 30 days overdue or scheduled report was 30 days overdue (= “N”)]. ICIS-NPDES uses “RNC resolution” codes to classify the resolution status of these violations (i.e., noncompliant, resolved pending, or resolved). These RNC resolution codes can be created automatically by ICIS-NPDES or be manually entered by an ICIS-NPDES user. ICIS-NPDES uses violation codes, RNC detection codes, and RNC resolution codes to create a single permit compliance status code for each permittee for each Federal Fiscal Year (FFY) Quarter. ICIS-NPDES generates this permit compliance status code approximately 2 ½ months after the quarter has ended.
This search allows the identification of DMR filers that have unresolved DMR non-receipt violations received later than 40 days after the DMR due date in ICIS-NPDES [i.e., these are facilities with DMR non-receipt Violation codes (D80 or D90) that have an unresolved RNC status code (1 or A) and contribute to a noncompliant permit status]. Although ICIS-NPDES automatically generates DMR non-receipt violation codes if values are not reported within 31 days, 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.
Prior to the NPDES Electronic Reporting Rule, ECHO did not show noncompliant permit compliance status codes for non-major DMR filers in most states (the exceptions being Arkansas and Louisiana, as requested by these two states), when the noncompliance was related to DMR non-receipt violations. ECHO was changed to show the permit compliance status (based on the RNC status code) for all DMR filers for the FFY Quarter that started on 1 July 2017 and following FFY quarters. EPA made these changes to help create an accurate and nationally-consistent set of data about the NPDES program and to provide greater transparency to the public on noncompliance.
- Choose to search by one type of location - either a state (geographic location based on facility address), EPA region, or permitting state from the dropdown menu.
- Facility Name or ID
- Search for facilities by name, partial name, or ID.
- State Region Code
- Choose a unique code from the dropdown menu to identify a particular region within a state. State or Permitting State must be selected first.
- Choose a county from the dropdown menu. State or Permitting State must be selected first.
- Permit Issuing Agency
- Specify whether the permit issuing agency is the EPA or a state. Selecting "Any" will not restrict search results.
- Permit Compliance Tracking Status
- This indicates whether permit compliance is currently being tracked.
- DMR Non-Receipt Tracking
- This indicates whether DMR non-receipt status is currently being tracked for the permit.
- Major - Returns any NPDES facility or activity classified as such by the regional administrator, or in the case of approved state programs, the regional administrator in conjunction with the state Director. Major municipal dischargers include all facilities with design flows of greater than one million gallons per day and facilities with EPA/State approved industrial pretreatment programs. Major industrial facilities are determined based on specific ratings criteria developed by EPA/State.
- Non-Major - Returns facilities not classified as "Major" by authorized environmental agencies. Prior to the NPDES eReporting Rule, DMR data was not required to be submitted to EPA. EPA therefore may not able to verify the accuracy or comparability of data for these permits, although the Agency tracks their names and locations and may have some data about their inspections and enforcement activity.
- DMR Submission Days Late
- Specify the minimum number of days since the DMR due date.
- DMR Received Date Between
- Specify the date range for the receipt of a DMR. Use the “DMR Received Date Between” feature to limit your search to unresolved DMR non-receipt violations (violation codes D80 or D90) where the corresponding DMRs were received by the NPDES program authority within the specified date range.
- DMR Monitoring Period End Date Between
- Specify the date range for the end of the monitoring period for a DMR. Use the “DMR Monitoring Period End Date Between” feature to limit your search to unresolved DMR non-receipt violations (violation codes D80 or D90) where the corresponding DMRs have monitoring end dates within the specified date range. The DMR monitoring period end date is set by the NPDES permitting authority.
- DMR Due Date Between
- Specify the date range for the due date of a DMR. Use the “DMR Due Date Between” feature to limit your search to unresolved DMR non-receipt violations (violation codes D80 or D90) where the corresponding DMRs have due dates within the specified date range. The DMR due date is set by the NPDES permitting authority.
- Limit results to permits with SNC DMR non-receipt status
- Select this option to restrict search results to permits having an RNC status of SNC due to DMR non-receipt violations.
- Limit results to permits with unresolved DMR non-receipt violations not resulting from one or more No Data Indicator (NODI) codes
- Select this option to restrict search results to permits with unresolved violations that were not a result of a No Data Indicator (NODI) code, considered invalid for compliance purposes, on a DMR.
- Limit results to permits with unresolved DMR non-receipt violations generated from:
- Options to restrict search results to unresolved violations generated from "Any No Data Indicator (NODI) code" or one specific NODI code (by selecting "A User-Specified No Data Indicator (NODI) code"). User-specified NODI codes can be selected from the dropdown menu.
Running a search will bring you to a table of NPDES permits matching your search criteria. You can select "Download Search Results" to download a CSV of the results table, or "Download Search Results Drilldown" to download a CSV of the drilldown results. Note that downloads are limited to 15,000 records.
To find more information about each specific non-receipt violation for a NPDES permit, click on the hyperlinked permit number to go to the drilldown table. Note that the drilldowns table shows additional data about all unresolved D80/D90 violations for the NPDES permit, not just those matching your original search criteria.
Data fields available in the search results and drilldowns include the following (click on the links below to jump to the Results Guide for detailed descriptions):
- External Permit Number
- The NPDES permit number formatted to define the general permit, the industrial classification, and the sequence number. This NPDES number may reflect either the permit or a facility covered by the permit. This field may also be referred to as the NPDES ID or Permit ID.
- Permit Name
- This is the name of the facility having the NPDES permit to discharge pollutants in the waters of the United States.
- Facility Name
- Company or permit holder name, as maintained by the ICIS-NPDES data system. The facility name may differ across EPA databases due to differences in reported information, change in ownership, use of parent or subsidiary name, etc.
- City, State Code, County, Zip Code
- City, state (two letter abbreviation), county and zip code where facility is located.
- State Region Code
- The unique code identifying particular regions within a state.
- EPA Region Code
- The EPA region where the facility is located. EPA has 10 regional offices that execute programs within several states and territories.
- Facility Type
- Indicates the type of facility owner (i.e., Publicly Owned Treatment Works (POTW), non-POTW, or federal government).
- Expiration Date
- Date that the current version of the permit expires.
- Issuing Agency
- The environmental agency that issued the permit.
- Permitting State
- The state that issued the permit.
- Major/Non-Major Status
- Each NPDES permit is defined by the program office as a major or non-major discharger. Unlike major permits, most non-major permits do not have federal monitoring requirements.
- Permit Compliance Tracking Status
- This Yes/No field indicates whether the permit is currently being tracked for compliance purposes.
- DMR Non-Receipt Tracking
- This indicates whether the permit is currently being tracked for DMR non-receipt status.
- Permit Type
- Indicates the type of NPDES permit (e.g., NPDES Individual Permit, General Permit Covered Facility).
- Master External Permit Number
- This is the unique identifier for the Master General Permit, which applies only to records with a permit type of General Permit Covered Facility. A Master General Permit is a NPDES permit that covers multiple facilities that have similar discharges and are located in a specific geographic area. A general permit applies the same or similar conditions to all dischargers covered under the general permit. It sets the conditions with which permittees will be required to comply. The Master General Permit contains no facility-specific data, and compliance and enforcement data are not associated with a Master General Permit (rather any data would be associated with the General Permit Covered Facility).
- Permit Status
- The permit status reflects the current stage in the permit life cycle. ICIS-NPDES designates a permit as Effective, Administratively Continued, Expired, Not Needed, Pending, Retired, or Terminated. See Permit Status for descriptions of the permit status values.
- Compliance Tracking
- "On" indicates that the permit is currently being tracked for DMR non-receipt compliance. This field will be "On" when either the Permit Compliance Tracking Status or DMR Non Receipt Tracking Status fields are "Yes."
- RNC Status
- The most recent official quarterly QNCR compliance status (Quarter 12) for the NPDES permit.
- Limits Present
- Indicates that the permit currently has limits (monitoring requirements or numeric limits) in ICIS-NPDES.
- First DMR NR Violation
- The first DMR non-receipt violation tracked. This date is the monitoring period end date associated with the earliest occurring DMR with one or more unresolved non-receipt violations (violation codes D80 or D90).
- Most Recent DMR NR Violation
- The most recent DMR non-receipt violation that has occurred. This date is the monitoring period end date associated with the most recent DMR with one or more unresolved non-receipt violations (violation codes D80 or D90).
- Number of Missing DMR Values (Unresolved)
- Number of all unresolved D80 and D90 DMRs for the NPDES permit. This count will match the number of records in the drilldown table.
- Number of Missing DMR Forms (Unresolved)
- Count of DMR forms (based on permitted feature number/monitoring period end date) where all values are unresolved DMR non-receipt violations. If any values are resolved, the DMR form is not counted.
