<-- Return to Free TRI Maps
Thank you so much for your interest in the 2004 TRI Pollution map layer(s). These were created using the latest data available from EPA. You may learn more about the annual Toxic Release Inventory (TRI) by visiting the EPA TRI website.
You can use the TRI map layers, along with the basemap layers below, as a basis for locating potentially hazardous chemical risks where you live, work and play. Click here if you are new to GIS and would like to learn more about it. We also have a free Learn2Map Tutorial that will help you learn the basics of GIS and to create your own digital maps.
Your order consists of the following map layer set(s):
- North Dakota
- South Dakota
First, download the general information archive. This includes base map layers for states, rivers, highways, cities, as well as TRI reports from EPA, a spreadsheet showing the facilities that could not be mapped plus a description of the database field names.
Next, use the url, username and password below to access your state file(s).
To avoid entry errors, it is best if you copy and
paste the username and password when asked for
rather than typing them in.
Note that some internet browsers may ask you for the
username and password a couple of times.
