Website Known Issues

This page describes known issues related to the ECHO website itself. For data quality problems, please see the Known Data Problems page.


  • On the homepage, the link to NPDES eRule Dashboards should load the Data Visualization Gallery with the "NPDES eRule View" quick filter selected.
  • The ECHO Interactive Map results view may display clusters from adjacent states due to imprecise geographic data. Geographic coordinates are approximated in ECHO if facilities do not have location information. These facilities are indicated by the Facilities with estimated latitude/longitude marker icon.
  • Facility search performance optimization is ongoing. If experiencing problems with slow facility searching or searches that won't load, please send information about the search ran, Internet browser, date, and time of day to ECHO Support
