Toxic Release Inventory reporting

Colorado follows the U.S. Environmental Protection Agency Toxic Release Inventory (TRI) Program exactly and has no additional TRI requirements except for Pollution Prevention Fees charged to TRI reporting facilities.
In 1984 a deadly cloud of methyl isocyanate from a chemical plant 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 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 EPA and, in Colorado, to us. EPA compiles this data in an online, publicly accessible national computerized TRI.
Reports must be submitted on or before July 1 each year. A separate copy should be sent to both EPA and us (unless reporting electronically using TRI-MEweb), and must cover activities that occurred at the facility during the previous calendar year. 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 also may report pollution prevention activities.
