Toxic Release Inventory (TRI) 

The Toxic Release Inventory (TRI) laws require facilities in certain industries, which manufacture, process or otherwise use certain toxic chemicals above specified thresholds, to report annually:

  • the amounts of toxic chemicals released into the environment
  • transferred off-site for treatment
  • recycled,
  • used for energy recovery
  • disposed of
  • managed on-site at the facility

The Minnesota EPCRA Program manages this information in a database called the Toxic Release Inventory (TRI).  The data are collected from various covered industries including manufacturing, electric utilities, commercial hazardous waste treatment and other industrial sectors.  The data reported are not necessarily derived from actual monitoring or measurements, but may be estimated from engineering calculations, material balance calculations, or published emission factors.

Minnesota Toxic Pollution Prevention Act

The Act requires each TRI facility reporting toxic chemical releases and transfers to develop a Pollution Prevention Plan.  The legislation:

  • establishes state policy encouraging the prevention of toxic pollution
  • provides technical assistance to help companies prevent toxic pollution by expanding the responsibilities and staff of the Minnesota Technical Assistance Program (MnTAP)
  • provides matching grants to help companies study or demonstrate the feasibility of applying specific technologies and methods to prevent pollution and to develop a Pollution Prevention Plan; these facilities must submit annual Pollution Prevention Progress Reports to the Minnesota Emergency Planning and Community Right-to-Know Act (EPCRA) Program

The Toxic Release Inventory (TRI) originated from Section 313 of the federal Emergency Planning and Community Right-to-know Act (EPCRA) of 1986 and Pollution Prevention Act of 1990.

The Minnesota Toxic Pollution Prevention Act went into effect in 1990.
