Mining Issues - Right to Know (TRI)

The Toxics Release Inventory (TRI) was established as a part of the Emergency Planning and Community Right-to-Know Act (EPCRA) of 1986. The initial purpose of the program was for chemical manufacturing facilities to report “releases” of certain listed substances to the air, land and/or water on an annual basis to the Environmental Protection Agency (EPA). The annual reporting of releases is accomplished with the submittal of Form R’s to the EPA by those facilities in the TRI program.
