Copperhead...I've been in the demolition business for a while and have had to deal with many oil tanks. Most of them are heating oil or diesel and the like and I can use the fuel myself. Others like hydraulic lift tanks are a different story. I have to transport them to an oil reclamation site and transfer the oil with an EPA guy watching. Also, you have to watch out with asbestos as there are so many regulations on it. Some yards will probably take the burner with it still attached, but others might turn you in to the EPA. I think you could work a better deal with homeowners/rental companies and get paid for your service. You might just have to eat this one since the deal has been struck, but he may give in a little for you.
