  "definition": "The 5-digit mail code for the facility address. Search Considerations: The Loading Tool searches use ZIP codes in two ways: (1.) To identify discharges from facilities located in the specified ZIP code. For this type of search, the search will produce results if the specified ZIP code matches the first five digits of any facility’s ZIP code in FRS or ICIS-NPDES. Zip codes are not required in FRS or ICIS-NPDES. If a facility's ZIP code is blank in the Loading Tool database, then the ZIP code search will exclude the facility. (2.) To identify discharges in watersheds that overlap with the specified ZIP code's geographic boundaries. For this type of search, the search will produce results if: (1) The specified ZIP code overlaps with a Hydrologic Unit Code (HUC) in the Watershed Boundary Database (2) The corresponding HUC is connected with a NPDES ID in the Watershed Boundary Dataset; (3) The corresponding NPDES ID is in ICIS-NPDES; and (4) The NPDES ID has DMR measurements in ICIS-NPDES. For more information see Overview of Watershed Data (https://echo.epa.gov/trends/loading-tool/resources/about-the-data#watershed). These data are from FRS and ICIS-NPDES.",
