The Environmental Protection Agency (EPA) requires industries and utilities to report releases of certain toxic chemicals that may pose a threat to human health and the environment. This requirement is called the Toxics Release Inventory (TRI) and identifies over 650 chemicals. Because of its efforts to prevent and reduce pollution, TVA only releases 23 of these substances in quantities large enough to require reporting.
As a federal agency, TVA must file annual reports on the amounts of TRI-listed chemicals released from all of its operations, not just from its coal- or oil-burning plants as required for nonfederal entities. Although the amounts are small from these additional operations, the releases reported by TVA are comprehensive and include substances that might be used for cleaning or maintenance activities at any TVA facility, including nuclear or hydroelectric plants.
TVA’s total TRI releases for 2017 were 13,952,404 pounds, down from the 2016 level of 18,857,423 pounds.
