Third part of the answer [continued]
NPI: A transfer is when an NPI substance
is not emitted directly to the environment
but instead goes into landfill, sewers or
tailings dams. If the substance is removed
from a facility for recycling, reprocessing
or reuse it is also a transfer. Transfers are
not currently included in the NPI but are
being considered following a review of the
current NPI NEPM.
