Toxic Release Inventory (TRI)

Notice: TRI reporting using paper forms is no longer permitted.


TRI-Made Easy (TRI-MEweb) software is now available for Reporting Year 2013 TRI reporting (due July 1, 2014).


Colorado facilities will NOT be able to report releases in Reporting Year 2013 by using TRI-MEdesktop/CD, sending in a diskette, or by sending in paper forms. Instead, ALL facilities must use TRI-MEweb.


Trade Secret Information

The only exception to the electronic TRI reporting requirement is for submitting trade secret TRI information. Facilities will continue to submit their trade secret reporting forms and substantiation forms in hard copy, as well as any revisions or withdrawals of previously-submitted trade secret information.



Colorado is participating in the TRI State Data Exchange. TRI data for Colorado facilities reported via the Internet to the Environmental Protection Agency (EPA) Central Data Exchange (CDX) using the EPA TRI-Made Easy (TRI-MEweb) software will also satisfy TRI reporting requirements for Colorado.


This data exchange allows EPA's CDX to automatically forward copies of electronic TRI submissions from Colorado facilities to the Colorado Department of Public Health and Environment, allowing Colorado to receive raw, electronic TRI data in real time. The reporting facility will receive instant receipt confirmation of its submission from CDX.


This method of reporting reduces the burden of dual reporting for Colorado facilities. This also allows both the EPA and Colorado to process TRI reports more efficiently and with less data entry errors.


For more information about this dual reporting or Colorado specific technical information or reporting, email the Colorado Superfund Amendments and Reauthorization Act (SARA) Title III program at cdphe.ppsaratitle3@state.co.us.





The State of Colorado follows the U.S. Environmental Protection Agency (EPA) Toxic Release Inventory (TRI) Program exactly and has no additional TRI requirements except for Pollution Prevention (P2) Fees charged to TRI reporting facilities. P2 Fee bills are sent out later in the calendar year.


In 1984 a deadly cloud of methyl isocyanate killed thousands of people in Bhopal, India. Shortly thereafter there was a serious chemical release at a sister plant in West Virginia. These incidents underscored demands by industrial workers and communities in several states for information on hazardous materials. Public interest and environmental organizations around the country accelerated demands for information on toxic chemicals being released "beyond the fence line" outside of the facility. Against this background, the federal Emergency Planning and Community Right-to-Know Act (EPCRA), also known as Superfund Amendment Reauthorization Act (SARA) Title III, was enacted.


Section 313 of EPCRA specifically requires facilities to report releases of over 600 designated toxic chemicals to the environment. The reports are submitted to the U.S. EPA and, in Colorado, to the Colorado Department of Public Health and Environment. EPA compiles this data in an on-line, publicly accessible national computerized TRI on the Internet at www.epa.gov/triexplorer/ .


Reports must be submitted on or before July 1 each year and must cover activities that occurred at the facility during the previous calendar year. A copy sent electronically using TRI-MEweb to EPA also satisfies the State of Colorado requirement. TRI facilities are required to report on releases of toxic chemicals into the air, water, and land. In addition, they need to report off-site transfers -- a transfer of wastes for chemical recycling, treatment, or disposal at a separate facility. Facilities may also report pollution prevention (P2) activities.



Facilities in covered NAICS codes (see links below) that have the equivalent of 10 or more full-time employees and meet the established thresholds for manufacture, processing, or "otherwise use" of listed chemicals (i.e., manufactures or processes over 25,000 pounds of the approximately 600 designated chemicals or 28 chemical categories specified in the regulations (see the TRI-Listed Chemical link below), or uses more than 10,000 pounds of any designated chemical or category) must report their releases and other waste management quantities (including quantities transferred off-site for further waste management).


If you are unsure of your facility's six-digit NAICS code, you can view the U.S. Census Bureau's SIC to NAICS crosswalk tables at: http://www.census.gov/eos/www/naics/concordances/concordances.html


Is my facility's six-digit NAICS Code a TRI-covered industry?

To verify if your facility's six digit NAICS code is a TRI-covered industry, visit the EPA TRI Program NAICS code verification site.


Is my chemical a TRI-Listed chemical?
You can verify if your chemical is TRI-Listed by viewing the EPA Chemical List for Reporting Year 2013 document.


Recent TRI Chemical List Changes

o-nitrotoluene was added to the TRI chemical list in November of 2013. Facilities that manufacture, process, or otherwise use o-nitrotoluene should begin collecting release information on the chemical for RY 2014 (forms due July 1, 2015) if TRI chemical use and other thresholds are met.


TRI Chemical List Changes: 1987 -- 2012

A listing of TRI Chemical List changes can be found by visiting the EPA Chemical List Changes page.

There is now only one TRI-ME application: TRI-MEweb (Paper reports and TRI-Medesktop are no longer available for TRI Reporting). TRI-Made Easy Web (TRI-MEweb) is a web-based application that you can access anywhere you have a connection to the internet. TRI-MEweb requires no downloads or software installs. This is now the only method to do TRI reports except for those including Trade Secret information.


Important: Please note that in order to use TRI-MEweb, certifying officials must register for the application in CDX.. While this can be done on-line, please allow adequate time for Registration. See links below for more information:
