The way the pipeline has benefitted caribou is the heat it produces. The
animals huddle under it when its really cold. It keeps some nutritional feed
items alive longer through the year in its vicinity. This heat also
improves fawn survival. Kind of like the monkeys in Japan that live in the
hot springs in winter or warm water discharges keep shad in shape for larger
fish in warm water systems during winter. Burying the pipeline would not
work since the perma frost would thaw and freeze cycle and possibly break
the pipeline, causing a hidden leak that would cause damage to the
environment. If those purposeing this are up front and truthful about the
measures to be taken, I am sure they would allow EPA inspectors in to check
that they were following procedure, if this is not already required.
