Using the Toxic Release Inventory (TRI)
WHAT ARE TRI FACTSIIEETS?
TRI Factsheets provide information on chemical releases for a specific, user selected, geographic area. The factsheets
utilize data from the annual National Analysi s conducted by the EPA. By July Ist of each year, certain facilities must
submit reports detailing their TRI chemical releases for the previous year. Once the EPA interprets and analyzes the
facility data on toxic releases, the TRI National Analysis is published. Factsheets generate succinct summaries of the
area's data.
CREATING TRI FACTSHEETS
One way to create a TRI Factsheet is to navigate to the TRI Program homepage and scroll down to "Find TRI Facts
for Your Community". You'll see the map shown below on the webpage. From here, you can select the geographic
area you're interested in. Searches can be made by State, Zip Code, City, County, Metropolitan Area, Watershed, or
Tribal land. Depending on what data you're looking for, you can select Total Releases, a release to a specific medium
(air, water, or land), Population, or Risk Screening Score. When you're ready, click "Go" to start the search.

UNDERSTANDING TRI FACTSHEETS
A number of data results are included on the factsheet. First is a map showing the locations of TRI facilities in the
area, along with regional facts and national comparisons. For the example below, in the most recent reporting year,
484 TRI facilities in Houston, Texas reported their releases to the EPA and all together they released over 17 million
pounds of TRI chemicals. As a whole, Texas ranks 22nd out of the 56 US states and territories for total releases per
square mile (with number 1 having the highest releases).

Next displayed is how the area manages its waste. Per the EPA's Waste Management Hierarchy, most encouraged is
source reduction, followed by recycling, energy recovery, treatment, and finally disposal. The graph shows the total
pounds of waste managed broken down by method. When you hover over each section, you are able to see exactly
how much waste was managed in that manner for that year. You also have the option of clicking on the most recent
reporting year to view a pie chart of the releases. In the example, we can see in 2013 Houston recycled about 193.76
million out of the total 466.68 million pounds of waste.

Next is a graph showing the area's on-site releases of TRI chemicals. A "release" is when a chemical is emitted to the
air, water, or disposed onto land. Transfers off-site for disposal are also considered chemical releases, but are not
shown in this graphic. The total number of pounds released is the height of the bar broken down by air, land, and
water releases. You can click on the most recent year to display a pie chart detailing the release data. In the example
below, a significant portion of Houston's TRI chemical releases are to the air and land. Looking at the 2015 pie chart,
specifically 48% of Houston's on-site releases of TRI chemicals were to the air and 42% to land.

The following graph identifies the facilities in the area with the highest releases. Similar to other sections in the
factsheet, the total pounds of TRI chemicals released is shown by the length of the bar, which is divided up according
to release type (air, water, land, and offsite disposal). When a section is hovered over, the amount released to that
medium is shown in comparison to the facility's total TRI releases. You can click on the name of the facility to access
more facility information. In the example below, in 2015, Huntsman International, LLC released a total of about 587.5
thousand pounds of TRI chemicals and of that about 585 .5 thousand pounds was disposed of off-site.

The final section of the TRI Factsheet shows pie charts showing what chemi cals were released into the air and water
in the latest reporting year. You can click on the chemical name to learn more about the health effects associated with
that chemical. For the example below, out of the 3.6 million pounds of TRI chemicals released into the air in 2015,
10% was hydrogen cyanide.
