Tier II reporting is a system used by states to collect and publish information about the hazardous chemicals stored and used by businesses and institutions in their area. The Tier II reporting system is part of the Emergency Planning and Community Right-to-Know Act (EPCRA), which was passed by the US Congress in 1986. The Act requires businesses and institutions that use or store hazardous chemicals to report this information to the state emergency response commission, the local emergency planning committee, and the local fire department. The information that is reported includes the name, location, and amount of each chemical, as well as any potential hazards associated with it. The purpose of Tier II reporting is to provide first responders and the public with information that can help them prepare for and respond to chemical emergencies.
