Alan,
I worked for a Petro-Chem company doing Hazardous Area work (mainly petrol pump work and Instrinically Safe controls).
I can back up what you say, the owners of tanks in the ground (the Fuel Companies)would charge anyone that needed maintenance or upgrade work at the rate of 300% of the time it took me to do the job.
Little country towns here have had to dig up their tanks because they just cannot afford the maintenance or whatever, this is a real smack in the face for people that depend on a fuel supply.
I lasted 6 months at that job, it was so depressing hearing the tales of owners being screwed by a company that makes billions (not millions).
