What is TRI?
Section 313 of the Emergency Planning and Community Right to Know Act (EPCRA) of 1986 was enacted to facilitate emergency planning, to minimize the effects of potential toxic chemical accidents, and to provide the public with information on releases of toxic chemicals in their communities. The Pollution Prevention Act (PPA) of 1990 mandates collection of data on toxic chemicals that are treated, recycled, and combusted for energy recovery. Together, these laws require facilities in certain industries, which manufacture, process, or use toxic chemicals above specified amounts, to report annually on disposal or other releases and other waste management activities related to these chemicals. The U.S. Environmental Protection Agency (EPA) maintains this information in a national database called the Toxics Release Inventory, which is available to the public via the Internet at www.epa.gov/tri.
The Toxics Release Inventory (TRI) is a database that contains detailed information on nearly 650 chemicals and chemical categories that over 23,000 industrial and other facilities manage through disposal or other releases, recycling, energy recovery, or treatment. The data are collected from industries including manufacturing, metal and coal mining, electric utilities, commercial hazardous waste treatment, and other industrial sectors to meet EPCRA section 313 requirements. The North American Industry Classification System or NAICS is used by business and government to classify and measure economic activity in Canada, Mexico and the United States. It has largely replaced the older Standard Industrial Classification (SIC) system.
Do I need to report to TRI?
The TRI Threshold Determination Tool helps facilities determine if they meet the threshold requirements for reporting to TRI. This audio visual tool will take approximately 6 to 8 minutes. If you are experiencing technical difficulties, please contact TRI (tri.us@epa.gov). For "captions" of the audio of this tutorial or you are unable to view the multi-media tutorial with your assistive technology, please refer to the text-equivalent Threshold Determination tutorial, which provides the text of the tutorial.
How do I report to TRI?
You may use TRI-MEweb to submit your TRI Form R or Form A Certification Statements electronically over the Internet. TRI-MEweb is available to all reporting facilities starting in reporting year 2007 (RY07). TRI-MEweb is Web-based application and requires no downloads or software installs. For more information, see the TRI-MEweb fact sheet (PDF). (2pp, 120KB, About PDF)
What chemicals are reportable to TRI?
The current TRI toxic chemical list contains 581 individually listed chemicals and 30 chemical categories (including 3 delimited categories containing 58 chemicals). If the members of the three delimited categories are counted as separate chemicals then the total number of chemicals and chemical categories is 666 (i.e., 581 + 27 + 58).
What training do you offer?
EPA hosts a number of Web -based training workshops for people involved with Toxics Release Inventory (TRI) reporting under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA).
Do you provide guidance for specific sectors or chemicals?
EPA provides extensive industry-specific, chemical-specific, and general TRI guidance for the public and the regulated community.
What if I discover that I should have been reporting to TRI in previous years?
If you discovered that your facility is or may have been in violation of Section 313 of EPCRA (TRI Reporting), please refer to EPA’s Policy entitled, “Incentives for Self-Policing: Discovery, Disclosure, Correction, and Prevention of Violations” (Audit Policy), 65 Federal Register 19618, April 11, 2000. You may qualify for having all gravity-based penalties waived if your facility meets all nine conditions of the EPA Audit Policy.
If you have 100 or fewer employees and discover that your facility is or may have been in violation of Section 313 of EPCRA (TRI Reporting), please refer to EPA’s Small Business Compliance Policy. EPA will eliminate or significantly reduce penalties for small businesses that meet the conditions of this policy, including voluntarily discovering violations and promptly disclosing and correcting them. This policy implements Section 223 of the Small Business Regulatory Enforcement Fairness Act (SBREFA) of 1996.
Can a first time filer participate in the State Data Exchange?
The TRI Program has been working with states to increase their participation in the State/EPA Exchange Network. The Exchange Network 
allows facilities to submit TRI information to both EPA and the states simultaneously through the Central Data Exchange (CDX). The Exchange Network also helps EPA, states, tribes, and territories exchange environmental information more efficiently and will streamline the acceptance and processing of TRI data by both EPA and the states.
How do I determine my NAICS code?
On June 6, 2006, EPA published a final rule requiring facilities to use NAICS codes, instead of the previously used Standard Industrial Classification (SIC) codes, to determine TRI reporting applicability and to identify their principal business activities for releases and other waste management activities during 2006, for reports due July 1, 2007 (71 Federal Register 32464; June 6, 2006). This final rule did not intend to add or delete any industry groups subject to TRI requirements; rather, EPA simply assigned NAICS codes to those SIC codes that were already subject to TRI reporting. A complete list of the 2002 NAICS codes for TRI facilities required to report for EPCRA §313 reporting is available.
A crosswalk between SIC codes and the corresponding 2002 NAICS codes (developed by the Census Bureau) is also available.
