Toxics Release Inventory
The Toxic Release Inventory (TRI) compiles the data on toxic chemical releases and waste management activities reported annually by certain industries as well as federal facilities and makes it available through downloadable files and several data access tools. The goal of TRI is to provide communities with information about toxic chemical releases and waste management activities and to support informed decision making at all levels by industry, government, non-governmental organizations, and the public. TRI contains information on releases of nearly 650 chemicals and chemical categories from industries including manufacturing, metal and coal mining, electric utilities, and commercial hazardous waste treatment, among others.
The TRI program has expanded significantly since its inception in 1987. The Agency has issued rules to roughly double the number of chemicals included in the TRI to approximately 650. Seven new industry sectors have been added to expand coverage significantly beyond the original covered industries, i.e. manufacturing industries. [TRI reporting industries primarily include manufacturing, metal and coal mining, electric utilities, and commercial hazardous waste treatment. Mobile sources emissions, which account for approximately 50% of all air toxics, as well as smaller sources such as gas stations and dry cleaners are not included in TRI.] Most recently, the Agency has reduced the reporting thresholds for certain persistent, bioaccumulative, and toxic (PBT) chemicals in order to be able to provide additional information to the public on these chemicals.
