Disclaimer: Preliminary 2011 TRI Dataset
Envirofacts provides access to individual 2011 TRI facility reports that have been submitted and processed by EPA. Please note that the preliminary 2011 TRI dataset is not yet complete. This dataset will be updated in August, September and October to capture additional submissions received by the TRI Data Processing Center.

The Toxics Release Inventory (TRI) Search retrieves data from the TRI database in Envirofacts.

TRI Search allows access to basic facility information, all forms submitted to EPA since 1987, aggregate chemical release data for all years reported, and relative risk information. The results display any facility that has reported from 1987 to present, even though the facility may or may not have submitted TRI data in the most recent reporting year. The last year of data displayed represents the last year TRI data was reported.

For each facility there is a link to summarized TRI information for years reported, Federal Registry System (FRS) facility information, and a corresponding Risk Screening Environmental Indicator (RSEI) report that provides a quantitative, relative estimate of risk posed by the facility based on the chemical released and potential exposure pathways. You may narrow your search by filtering through facility name/ID, geographic location, standard industrial classification, and chemical names/CAS numbers.

Facility Selection

Geography Search

Enter a partial value for any geography option except for the state value. For city and county, you must enter the state value. We strongly recommend that you enter a small geographical area to begin the search since Envirofacts contains a large number of facilities.

Facility Industrial Classification Search

Select a search option from the drop down menu. For the “Equal to” option enter a 4-digit SIC code. For “Beginning with” or “Containing” enter up to 4 digits.

  • OR

Select a search option from the drop down menu. For the “Equal to” option enter a 4 to 6-digit NAICS code. For “Beginning with” or “Containing” enter up to 6 digits.

Chemical Name Search

Enter the chemical name or lookup the appropriate CAS number by clicking on the "Lookup Pollutant codes and CAS Numbers" link. If both Chemical Name and CAS number are entered, only CAS Number will be used in the search.
