Important Note on 2009 TRI Reports: The XML schema and documentation that supported Release Year 2008 will also be used to support Release Year 2009 reports. There are no changes to the XML schema, Flow Configuration Document, or Data Exchange Template for Release Year 2009.

Data Flow Implementation Guide – This guide provides a high-level overview of the data flow including advice about when to consider implementing the flow and a summary of planned improvements to the flow’s design and usability.

The Toxic Release Inventory is a U.S. EPA program enacted as part of the Emergency Planning and Community Right to Know Act (EPCRA) of 1986.
Every year, tens of thousands of facilities in the United States submit reports to EPA and the States on releases and transfers of certain toxic chemicals. This data exchange allows EPA's Central Data Exchange (CDX) to automatically forward copies of electronic TRI submissions to state Exchange Network Nodes. The TRI data exchange allows states to receive raw TRI data in real time. It also reduces the burden on reporting facilities, allowing them to submit only once through CDX, with the data being sent to both EPA and their state simultaneously. Facility submissions sent directly through CDX to EPA and the states are known as the "Stage 1" submissions.

"Stage 2" of the TRI data exchange was established in 2006. Stage 2, allows states that join the TRI State Data Exchange to save resources usually spent for data entry and reconciliation by getting their entire state’s data set electronically via CDX. This includes data that is submitted on diskette or paper or by a first time filer. (Note: When a facility makes a paper or diskette submission or files for the first time, it is still required to report to both U.S. EPA and the state in which it is located.) An updated Memorandum of Agreement (MOA) that outlines some of the business rules associated with this new service is presented below.

The TRI Program holds monthly conference calls on the TRI Data Exchange. To receive notifications about these calls, please contact Zachary Scott at Scott.Zachary@epa.gov.

Please note that version 4.0 of the TRI XML schema and documentation will be reused to support Release Year 2009 reports. There are no changes to the XML schema, Flow Configuration Document, or Data Exchange Template for Release Year 2009.

The NTG Conformance Committee has received and reviewed the TRI documentation package and deemed the schema and supporting flow documentation acceptable for use on the Exchange Network. The following links are to implementation resources for the TRI data exchange version 4.0.

The following resources were used for reporting year 2007. Network partners should not map to these XML schemas for the current reporting cycle.

The following resources were used for reporting year 2006. Network partners should not map to these XML schemas for the current reporting cycle.

The following resources were used for reporting year 2005. Network partners should not map to these XML schemas for the current reporting cycle.

The following resources were used for reporting year 2004. Network partners should not map to these XML schemas for the current reporting cycle.

States participating in the TRI data exchange must complete a Memorandum of Agreement with U.S. EPA that outlines the specific roles and responsibilities between the State and EPA for the purposes of successfully transmitting TRI data via the Exchange Network. You can download a model MOA below.

Pilot Project Lessons Learned
The States of Michigan, South Carolina, Virginia, and Indiana participated in the pilot project that launched the TRI data exchange. Each state compiled a Lessons Learned document to help other partners better understand the implementation process and anticipate challenges before beginning.
