Releases to Air, Land, and Water
On-site releases in the Toxics Release Inventory (TRI) are reported by where they were released: to air, land, or water.
Releases to air are classified as either fugitive or stack. Fugitive releases (or non-point source emissions) include evaporative losses, leaks, and releases from building ventilation systems. Stack releases (or point source emissions) come from known points such as stacks, confined vents, ducts, pipes, or other confined air streams. Stack releases also include releases from air pollution control equipment and storage tank emissions.
Releases to water are discharges to streams or water bodies. These include process outfalls, such as pipes and open trenches, releases from on-site wastewater treatment systems, and stormwater runoff.
Releases to land include disposal to landfills, land treatment, surface impoundment, underground injection (not allowed in Washington State), and other disposal methods. Land treatment is a disposal method — when a waste that contains a TRI chemical is applied onto or mixed into soil.
Compared to 2014, on-site releases increased by four million pounds (23.1 percent). Releases to water remained nearly unchanged, air releases dropped slightly (4.5 percent), and land releases jumped up by 74.5%. Three more facilities reported in 2015.
