(Seattle—Jan.
16, 2013) The U.S. Environmental Protection Agency has published the 2011 Toxics
Release Inventory (TRI) National Analysis, providing information to communities
about chemical releases to air, water and land across the nation.
Due to
extensive metal mining activity and the permitted disposal of large volumes of
regulated mining waste , Alaska had the highest TRI releases in the nation and
had a 25 percent increase in releases from the previous year. TRI releases from
Alaska metal mines can be attributed to increased production, changes in the
production process or variations in the ore body’s composition.
Because
mining waste facilities handle large volumes of material, small changes in
chemical composition of mining ore can lead to significant changes in the
overall amount of toxic chemicals reported. Since 1998, when metal mining was
added to TRI, 99 percent of Alaska’s reported releases have come from the
regulated disposal of waste rock and mine tailings.
TRI releases include permitted air emissions
and wastewater discharges; management of wastes in regulated disposal
facilities; and accidental spills and releases. Land releases include all
chemicals disposed on land within the boundaries of the reporting facility,
including landfills, land treatment and holding ponds. TRI facilities in Alaska
are regulated under EPA and State of Alaska permits with monitoring and
compliance requirements designed to protect public health and the
environment.
The
TRI program requires certain industries to report information on toxic
chemicals, waste management and pollution prevention across the country.
Industries that must report to TRI include manufacturing, metal mining, electric
utilities and hazardous waste facilities.
In general, most categories of TRI releases
increased in 2011 across the country. Hazardous air pollutant emissions and
releases to surface water decreased in Alaska, as they did in the rest of the
country. Mercury releases to air, total air releases and land releases decreased
nationally but increased in Alaska due to mining.
Chemicals
are placed on the TRI list based on their potential to cause adverse effects to
human health or the environment. The TRI data alone do not reflect actual health
exposures to chemicals or risk posed by releases.
EPA
improved TRI national analysis report by adding new information about facility
efforts to reduce pollution, insights into why air releases are declining, and
an enhanced analysis of releases on tribal lands. With this report and EPA’s
Web-based TRI tools, citizens can access information about TRI-listed toxic
chemical releases in their communities and across the country.
Facilities must report their toxic chemical
releases to EPA under the federal Emergency Planning and Community Right-to-Know
Act (EPCRA) by the beginning of July each year.
