The Alaska Native Villages are associated with Federally recognized tribal entities. 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, was 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 Tribal Identification web service (found at http://www.exchangenetwork.net/data-exchange/epa-tribal-identification-tribes/). The relationships between Alaska Native Villages and Tribal Entities were built during earlier work by EPA's American Indian Environmental Office (AIEO) while developing the Tribal Information Management System (TIMS).

EPA has simply attempted to collect certain readily available information relating to Indian country locations. Questions concerning data should be referred to the originating program or Agency which can be identified in the Envirofacts tribal query metadata file https://www.epa.gov/enviro. The Indian country locations shown here are suitable only for general spatial reference and do not necessarily reflect EPA's position on any Indian country locations or boundaries or the land status of any specific location. The inclusion of Indian country information on the EnviroFacts website does not represent any final EPA action addressing Indian country locations or boundaries. This information cannot be relied upon to create any rights, substantive or procedural, enforceable by any party in litigation with the United States or third parties. EPA reserves the right to change information on EnviroFacts at any time without public notice. EPA uses the US Census Bureau 2010 tribal boundary layer data when developing environmental data query responses for tribes in the lower 48 United States and Bureau of Land Management Alaska State Office when developing environmental data query responses for tribes in Alaska. The tribal boundary locations identified are suitable only for general spatial reference and do not necessarily reflect EPA's position on any Indian country locations or boundaries, or the land status of any specific location. EPA seeks to use the best available national federal data and may refine the tribal boundary layer in the future as more accurate national federal data becomes available.
