I got it now. Frankly, this is very foreign to me since my employers have always gone the route of performing "due diligence" on environmentally sensitive properties beforehand. So I talked to my boss about the situation and he remembered researching this a while back, and talking to someone from AIG about it. I did a quick internet search and found this site:

1 – He did this research a couple of years ago and the premium was substantial. Be ready to have your margin eaten away.
2- He reminded me about the fact that gas stations {at least those in our state} are mandated to change to double-wall tanks within 3-years. This would mean additional expense.
3- The fact that you get insurance does not mean that you can’t skip due diligence. There might be some liability there if you don’t require an environmental assessment. It has to do with being classified an “innocent purchaser”
Good luck on your search for a policy.
