To build up in the body tissue of living things through
contaminated food sources. As the toxins move up the food
chain, they increase in concentration.
Chemicals that possibly, probably, or definitely cause cancer
The U.S. Environmental Protection Agency (Exit Ecology) defines environmental
justice as the fair treatment and meaningful involvement of all
people regardless of race, color, national origin, or income
with respect to the development, implementation, and enforcement
of environmental laws, regulations, and policies. EPA has this
goal for all communities and persons across this Nation. It will
be achieved when everyone enjoys the same degree of protection
from environmental and health hazards and equal access to the
decision-making process to have a healthy environment in which
to live, learn, and work.
Fugitive releases, or 'non-point' source emissions, include
evaporative losses, leaks, and other releases from building
Listed TRI Chemical
The current TRI toxic chemical list contains 581 individually
listed chemicals and 30 chemical categories. The
Environmental Protection Agency (EPA) modifies this list
periodically. To view the current list of TRI toxic chemicals
Material Safety Data Sheets (MSDSs)
Detailed information sheets that provide data on physical and health
hazards of chemicals to workers along with associated
protective measures. Over 700,000 products have MSDSs,
which should be easily accessible to employees in their work
environment. With the implementation of the Global Harmonized
System, many MSDSs are starting to be phased out and replaced by
SDS. More information is available at the
Department of Labor and Industries' website.
The material remaining after target minerals have been
separated during the mining process. Tailings may contain
trace quantities of metals found in the host ore, and they may
contain amounts of added compounds used in the extraction

Remains in the environment for long periods of time and are not
Persistent, Bioaccumulative, and Toxic (PBT)
PBTs are persistent, bioaccumulative, and highly toxic
pollutants. These long-lasting substances can build up in
the food chain to levels that are harmful to human and ecosystem
health. They are associated with a range of adverse health
effects, including nervous system damage, reproductive and
developmental problems, cancer, and genetic impacts, such as
The discharge point of a waste stream into a body of water.
Examples include pipes and open trenches.
When EPCRA was first enacted, the TRI Program focused on the
releases and other waste management activities of the
manufacturing sector - facilities in
SIC codes 20-39. To provide the public with a more
complete picture of the toxics in their community, EPA undertook a detailed examination
of non-manufacturing industries to determine which may be
significant generators of toxic chemical releases and other
wastes. This effort focused particular attention on
sectors linked to manufacturing -
those providing energy, further managing products, or further
managing waste from the manufacturing sector.
On May 1, 1997,
EPA (Exit Ecology) added seven industry sectors to TRI: metal mining, coal
mining, electrical utilities that combust coal and/or oil,
hazardous waste treatment and disposal facilities, chemical
wholesale distributors, petroleum bulk stations and terminals,
and solvent recovery services.
Stack, or 'point source' emissions, comes from known points
such as smokestacks, confined vents, ducts, pipes, or other
confined air streams. Stack releases also include air
releases from air pollution control equipment and storage tank
Natural topographic depressions, man-made excavations, or diked areas designed to hold an
accumulation of liquid wastes or wastes containing free liquids.
Surface impoundments include holding, settling, storage and
elevation pits, ponds, and lagoons.
The subsurface emplacement of fluids through wells. TRI
chemicals associated with manufacturing, the petroleum industry,
mining, commercial and service industries, and federal and
municipal government related activities may be injected into
Class I, II, III, IV, or V wells, if they do not endanger
underground sources of drinking water, public health or
the environment. This type of land release is not allowed
in Washington State.
