This guy has some serious knowledge on tree roots and their habits.  He does
seminars on tree roots across North America. If you have a chance to hear
him it's well worth it.

profile oil company on how roots of trees/shrubs are decaying/corroding the
protective coating on oil and gas pipe lines.

pipes, roots are attracted to this and are now "wrapping" themselves around
the lines. They are claiming that this(roots causing damage) is causing the
protective coating to decay or corrode, which they say, increases the risk
for pipe failure.

underground oil & gas infrastructure and for future additions, essentially
it's a oil and gas easement. 

> Trees and shrubs have been planted (1989) on this city easement to provide
a visual barrier to the industrial and commercial areas of Regina. The
company has signed an agreement to this, back in the early 90's. 

> They are requesting that the plant material be removed because there is a
concern that if the roots continue to corrode or decay the coating, this may
cause leaks, explosions and loss of life.

there is natural gas, oil and other underground petroleum utilities. This
decision could be precedence setting, even for homeowners.

well.

here in Regina and that if a tree is of a public safety concern and we've
determined this, we will remove it.

support this. Is there any documentation out there that supports their
claim?
