    TRI is a USEPA database containing data on disposal or other releases of over 600 toxic chemicals from thousands of U.S. facilities and information about how facilities manage those chemicals through recycling, energy recovery, and treatment. One of TRI's primary purposes is to inform communities about toxic chemical releases to the environment.

Search for Tier II Facilities with Hazardous Chemicals
  1. Searches can be performed on Facility name, Report Year, City, Zip Code, County & Street Address.
  2. You can narrow your search by using multiple fields. The results will return only those items that match all of your search criteria.
  3. The wild card character (*) can be used to match any character(s) within the specified field value.
    Example: entering *spring* into the city field will return results for "Springfield", "Spring Grove", "Willow Springs", etc.
    The wild card character can be used in all fields. It can also be used multiple times within the same field.
  4. Selecting the "Only EHS facilities." checkbox will limit the results to only those facilities matching your search criteria that reported at least one extremely hazardous substance (EHS).
  5. After a search has been performed, you can click on any of the column headings to sort the results by that column.
    The first time you click on a column the results will be sorted in ascending order, clicking on the same column again will sort the list in descending order.
  6. Once you have located the facility and reporting year you are searching for within the search results, click on the report year for that item to view the detailed Tier II report.
  7. If you would rather have a listing of all reports than use the search capability, a comma separated file (.csv) can be downloaded here, along with a text file containing the file layout and description. The report file is approximately 60 megabytes.
