Description of State Fact Sheets

The state fact sheets summarize the basic Toxics Release Inventory (TRI) data for each state from 2002. The TRI is a publicly available database containing information about releases and other waste management of toxic chemicals reported by industrial facilities. The TRI was established by section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA) of 1986. The Community Right-to-Know provisions of EPCRA are intended to provide information to the public about the presence and release of toxic chemicals in their communities. Following passage of the Pollution Prevention Act of 1990, the TRI was expanded to include reporting of additional waste management and pollution prevention activities.

By July 1 each year, facilities must report their estimated amounts of releases and other quantities of toxic chemicals managed as waste for the preceding calendar year. Facilities provide this information to EPA and to the state in which they are located. For further information about TRI and for assistance in obtaining TRI documents, contact the EPCRA Information Hotline at 1-800-424-9346. For assistance in obtaining access to the data, contact the TRI USer Support Service at (202) 566-0250 or via e-mail at For further information about individual state TRI programs, select the TRI State Coordinator link at the bottom of the fact sheet for that state.

Each state fact sheet provides the following:

Note that "Total on- and off-site disposal or other releases" (amounts reported in Sections 5 and 6) and "quantity disposed of or otherwise released on- and off-site" (amounts reported in Section 8) may not be the same. This difference arises primarily from the types of disposal or other releases reported on different sections of the Form R.

Although total amounts analyzed in these two categories are often the same, they may differ to the extent that disposal or other releases associated with catastrophic events, remedial actions, or other one-time events not related to production occur.

For the same reason, the quantity used for energy recovery offsite (Section 8.3), quantity recycled offsite (Section 8.5) and quantity treated offsite (Section 8.7) do not include transfers for recycling, energy recovery, and treatment (including POTWs for non-metals) reported in Section 6 to the extent that amounts from one-time events are reported. Once again, the relevant parts in Section 8 include only production-related wastes and not amounts from one-time events whereas Section 6 includes all off-site waste management amounts.

Other reasons also contribute to the different quantities reported in different sections of the Form R. For example, an amount of less than 1,000 pounds may be reported in ranges in Section 5 and 6 whereas an exact amount must be included in Section 8. Furthermore, facilities may round off amounts, except those for PBT chemicals, to two significant digits.
