EPA Says Toxic Releases Decreased in Arizona

The US Environmental Protection Agency says toxic releases into the environment from facilities in Arizona dropped 9% in 2007, the latest data available. The EPA says the decline is mainly due to a decrease in on-site land releases from mining facilities. The data comes from the EPA’s Toxics Release Inventory, commonly referred to as TRI. It’s one of the EPA’s largest publicly available databases, giving communities valuable information on more than 650 toxic chemicals released by various industries.
The information is calculated by the facilities and reported to the EPA, as required by law. The latest information shows that overall on-site land releases decreased by 8%. Air releases decreased by 13%. But water releases increased 17%.
According to the EPA, the top two Arizona facilities for total releases of all chemicals are Freeport McMoran Miami and the Asarco Ray Complex.
