My infrastructure engineering colleagues were working on the design of the bunds to contain spillage and so on. Actually, just looked at Google Earth rather than Google Maps so I could look at the site history and I see that while some of the storage tank area is still vacant, there are indeed new tanks in place on other parts which I thought were those left intact (or are they all to be replaced?). Also, remarkably or so it seems to me, part of the original tank farm is now a large Amazon distribution centre!
