Posted By Brett Day Have worked on petrol station projects in the past where the client has put new (larger) tanks in, the old tanks still being leak tight have been filled with expanding foam, a note made of the location and capped rather than being dug up. As environmental isn't my strong point does anyone know if there is any prohibition on this as a current practice? Alternatively any contacts I should be speaking to. I have spoken to the environment agency but they told me we have someone who can help, I was passed around on hold and then cut off. If anyone knows this 'person in the know' and has a contact number it would be greatly appreciated.

Posted By Richard Mathews I filled my petrol tank with foam, now the bloody car wont start. (sorry, it is Friday)

Posted By JEFFREY SMITH The foam specified should be an 'inert' foam. The MOD have a couple of hundred sights around the country where this has been done. The foam goes into the tank and hardens effectively trapping any horribles and therefore cannot leak back into the environment. I am not sure if this can be cut but presumably since inert, shouldn't cause any problems. Hope this helps.

Posted By renown Like Fred, last time I dealt with a disused petrol tank, I had to contact the local Fire Brigade and have the tank filled up with concrete. The Fire Officer had to be in attendance when this was done. This was back in 2000.

Posted By B.Gee The local petroleum officer should be able to provide advice. As for filling and recording for future re-development it is very rare that the site owners have records of the fill material and in some (most)cases if the tanks even exist! B.G
