    Oil leak HELP!

    If I was you , I would dig up and expose top of tank. Look for a return line , most oil leaks on ust's are from this.
    If you do find this remove and replace it, while it's open I would change all vent,fill,return,supply lines.Swing joints on fill and vent piping. On the supply and return use a covered line that is UL approved for earth contact. If you don't find any oil here time to call in a vacuum truck and replace tank. Good luck , you might need it. P.S. to find where to dig we use a probe to find how tank is laying a 6000 gal tank could be from 16' to 29' long. Hope this helps John@Reliable

    Haz Mat Liability

    If there is a leak , does your state consider it a hazmat spill, and do you have the training and certification to deal with it? The state agencies are interested in generating revenue,and fines are a great source.With a 6000 gal tank you might be better off getting a tank service company involved.
