seller removed Underground oil tank. do i need a ceftificate?

[Doron Rice]

I am going to put an aggressive offer on a REO property I really like for a flip. the Bank disclosed that there was an underground oil tank that was recently removed. Do I need to ask for a clearance certificate before closing or once I bought a property without an underground oil tank it isn't my responsibility (the seller obtaining the responsibility, even after the transfer of title)? This is an as is deal in NJ. Thanks!
