are, but around here, new underground tanks are no longer steel - only
plastic or composite are used.

I was consulting for a major oil company a while back. Based on an
analysis
of their known tank inventory and their site count, I estimated that there
were over two thousand (!) tanks that were "lost" - no one knew exactly
where they were located or what condition they were in. Some might have
been
replaced with composite and not documented, others removed etc. Some
might
be sitting there untested and leaking. These aren't 400 gallon tanks, of
course, but 20,000 - 50,000 liter. It would be nice to believe that the
local users are testing them regularly and checking for leaks, but...

Collectively, the tanks in N.A. leak an Exxon Valdez a month, IIRC.

You are so full of ****!

Show me some figures that back up your bull****.
