Tribes Services
EPA provides three tribal data services to make it easy to comply with the Tribal Identifier Data Standard:
- Tribes Names Service is the EPA tribal web service for non-geospatial systems. It automatically maintains accurate and current tribal information like current tribal names, BIA codes, and EPA Internal Identifiers.
- Tribal Areas Service is the EPA tribal web service for geospatial systems. It includes geospatial data, current tribal names, BIA codes, and EPA Internal Identifiers.
- Tribe Entity Mapping Spreadsheet (xlsx) is an Excel document that contains current and historic tribal data like tribal names, BIA codes, EPA Internal Identifiers, and associated EPA regions.
Data provided by these services are regularly updated. Tribal names are obtained from BIA’s official list of federally recognized tribes that is published at least annually in the Federal Register. The Tribes Services apply a unique EPA Internal Identifier to each tribe. This ensures the correct identification of tribal partners and can be used to identify name changes over time. EPA Internal Identifiers are more reliable and available that BIA codes, which are not currently provided for Alaska Native entities and some American Indian entities.
