EPA Adds Hexabromocyclododecane (HBCD) Category to Toxics Release Inventory List
EPA has finalized a rule adding a hexabromocyclododecane (HBCD) category to the Toxics Release Inventory (TRI) list of reportable chemicals. This action will expand the scope of chemicals subject to TRI reporting and provide communities with more complete information on toxic chemical releases.
HBCD is a brominated flame retardant used mainly in expanded polystyrene foam (EPS) and extruded polystyrene foam (XPS). EPS and XPS are used primarily for thermal insulation boards in the building and construction industry. HBCD may also be used as a flame retardant in textiles. Concerns about releases and uses of HBCD have been raised because it is found worldwide in the environment and wildlife and has also been found in human breast milk, fat tissue and blood.
EPA also determined that HBCD meets the environmental effects criterion for listing because it is highly toxic to aquatic and terrestrial organisms. Additionally, HBCD bioaccumulates and is persistent in the environment. As a result, HBCD meets the TRI criteria for a Persistent, Bioaccumulative, and Toxic (PBT) chemical and is designated as a chemical of special concern, with a 100-pound reporting threshold.
