TRI Search User Guide

The Toxics Release Inventory (TRI) contains information about releases and transfers of more than 650 toxic chemicals and compounds to the environment.

This page is a brief user guide to the TRI Search. Use one or more search options at the same time to narrow results. Only facilities matching all selected criteria will be returned.

On this page: Facility identification · Geography · SIC · NAICS · Chemical · Search values · TRI search results · Envirofacts TRI report · Usage constraints

Facility Identification Search Option

Facility Name

Enter a complete or partial facility name to retrieve facilities with matching names. When entering a partial name, selecting the “Containing” option may provide better results the first time you search.

TRI Facility ID

Enter the complete or partial TRI Facility ID number assigned by the TRI Program System Office. The TRI Facility ID cannot exceed 15 characters.

Geography Search Option

Select from the following geography search fields: ZIP Code, Address, City, County, and State.

ZIP Code

Enter one or more digits. ZIP+4 is supported.

Address

Enter a complete or partial street address.

City

Enter a complete or partial city name. Including the two-character state postal abbreviation helps narrow results.

County

Enter a complete or partial county name and a two-character state postal abbreviation. Including the state abbreviation helps narrow results.

State

Enter a two-character state postal abbreviation. The table below lists abbreviations and state names.

Note: Envirofacts contains a large number of facilities. Starting with a small geographic area is strongly recommended.

Standard Industrial Classification (SIC) Search Option

SIC Code Description

Enter a complete or partial SIC code description to retrieve matching SIC codes. For example, entering “metal” returns facilities with SIC descriptions containing “metal.”

SIC Search

Enter a four-digit SIC code. The first two digits define the major business sector, and the last two digits identify the facility’s specialty within that sector.

Note: If both SIC Code and SIC Code Description are entered, only SIC Code is used.

North American Industry Classification System (NAICS) Code Search Option

NAICS codes are six-digit numbers used to categorize business activities in the United States. A facility may be comprised of one or more establishments, and each establishment may have a different NAICS code.

The digits in a NAICS code represent increasingly specific levels of classification:

NAICS digits and example levels of granularity
Number of digitsExample NAICSDefinition / granularity
Two31xxxxManufacturing
Three311xxxFood manufacturing
Four3115xxFood manufacturing, dairy products
Five31151xFood manufacturing, dairy products (not frozen)
Six311511Food manufacturing, dairy products (not frozen), fluid milk

Chemical Search Option

Chemical Name

Enter a complete or partial chemical (parameter) name. Some chemicals have multiple common names; if the facility reports the chemical under a different name, it may not be returned.

Chemical Abstract Service (CAS) Number

Use the “Lookup Pollutant codes and CAS numbers” link to find a CAS number, or enter the CAS number directly.

Search Values Option

Select one of the following options:

  • “Use Multisystem facility information to perform facility search” to identify facilities using facility information from all program systems.
  • “Use TRI facility information to perform facility search” to identify facilities using TRI facility information only.

Usage Constraints

Information in the TRI database can be freely accessed through this search. The complexity of the search is up to the user. Searches that return large volumes of data may terminate prematurely due to system limitations. To reduce the likelihood of timeouts, build searches that return smaller batches of data and end your session as soon as results are retrieved so others can access the database.
