TRI data can help you learn about chemical releases and pollution prevention activities
reported to EPA by nearby industrial and federal facilities.

What can tribal communities learn from TRI data?
TRI is a publicly available database with web-based tools that allow
communities to access information about chemical releases to air,
water, and land. Facilities in 30 different industry sectors submit TRI
reports annually to EPA about the chemicals they manage and
release into the environment, as well as about the activities they
have implemented to reduce waste generation. Facilities that are
located on the lands of federally recognized tribes are also required
to submit a copy of their annual TRI reports to a designated
representative of each of the affected tribes.

TRI data are easy to access
online through factsheets,
interactive charts and graphs,
and web tools.

TRI includes information about
chemical releases to air, water,
and land from many industrial
facilities all in one dataset.
In recent years, the majority of
TRI chemical releases on or
near tribal lands have been to
the air and land.

How can tribal communities access TRI data?
The TRI Tribal Search Interface provides interactive charts to easily access data about releases from TRI
facilities on or within 10 miles of tribal lands. It is available at Find other tools

Are tribal communities at risk from chemical releases?
While TRI data can be used to identify potential chemical hazards on or near tribal lands, these release
data alone are not sufficient to determine exposure or to calculate potential risks to human health and
the environment. To better understand potential long-term risks in your community, TRI data should
be considered along with other information, such as the toxicity of the chemical(s), quantity released,
route of exposure, and other information.
