This layer is used to support EPA's analysis of regulated facilities, and environmental monitoring stations with regard to existence on or near Tribal lands. ANCSA (Alaska Native Region or Village Corporation) Selected and Conveyed Lands provided by BLM Alaska State Office, were used to create this layer. Alaska Native Villages areas were selected and centroids were calculated to provide estimates of the center of each village area. Federally recognized Tribal Entity Names are provided by EPA's Tribe Entity Mapping Spreadsheet (found at https://www.epa.gov/data/tribes-services ). The relationships between Tribal Areas and Tribal Entities were built during earlier work by EPA's American Indian Environmental Office (AIEO) while developing the Tribal Information Management System (TIMS), and updated to account for the latest Tribal Area and Tribal Entity additions.
In March 2025, an update was made to the CFRTRIBE and NAME fields for the Louden Tribe (EPA ID: 100000408). A previous tribe name update had removed 'Galena Village' from the tribe name, and the updates to these fields were made to reflect this change.
