> needed to store oil above ground due to EPA regulations, but needed it stored underground to satisfy the fire department regulations.
Did they try building tanks both above and below ground, connecting them with two pipes so there's a circle, and constantly pumping it along that circle so it is not stored anywhere but merely in transit through both areas?
