Steps

  1. Query the NPDES Noncompliance Report REST service (echo.epa.gov/tools/web-services/npdes-noncompliance-report) with a facility ID or NPDES permit number
  2. Specify the reporting quarter/year of interest, since NNCR is a point-in-time quarterly compliance snapshot
  3. Retrieve compliance and enforcement status data for the specified facility/permit and quarter
  4. Cross-reference against the CWA facility search or Effluent Charts service for underlying DMR detail behind a flagged noncompliance
  5. Repeat across quarters to build a noncompliance trend for the facility
