Tribal Windows to the Environment
The Tribal Windows to the Environment (TWE) system was developed for
EPA’s American Indian Environmental Office (AIEO). TWE identifies
and maps the major facilities regulated by, or of environmental interest
to, EPA and other federal agencies that lie within the boundaries of
a tribe. TWE may be used to launch a wider query and data extraction
from Envirofacts, EPA’s data warehouse of integrated environmental
information.
