The 2001 Toxic Release Inventory (EPA always takes a year too long) was recently released. I have created a map file of these facilities for you to use with ArcExplorer (see my tutorial for more on how to use), Arcview and most other commercial GIS programs. Using the tutorial you can create a map with various base layers in addition to the toxics. Click here to download. You may also download There are two Excel files here. One contains the data to create the TRI map and the other is a list of the records (facilities) that could not be mapped because their locational data was too inaccurate.

I've also uploaded two files for Humboldt County. The first, humb-chem-releases-2001.xls, lists chemicals and amounts released in Humboldt County. The second, humb-fac-releases-2001.xls, lists each facility and their releases. To find out more about the risks associated with specific chemicals that are released, check

If you'd like, you can download my work-in-progress map of Humboldt County. It comes with an Arcexplorer project file (see learn2map tutorial) and several map layers including the 2001 TRI, Yurok and Hupa tribal boundaries, Simpson Timber lands, Aboriginal Yurok territory (gathered from a variety of historical resources), US Forest Service and National Park boundaries, rivers and streams, streets, and highways. Note that this really is a work-in-progress. Some of the data is quite dated, some is missing (like rivers and streams for Del Norte and Siskiyou counties if you are doing research in Yurok or Hupa territory). Feel free to use it in any way that you like for the class, but best not to use it beyond that. If you do want to explore/use any of this further, email me at [email protected] and we can talk about it. Click here to download. Note that this file is over 4 mb.
