My Lords, I intervene briefly to support quite a lot of what the noble Lord, Lord Greaves, has just said. This business of language is absolutely critical. Part of the problem is the splitting of what is now a holistic process through the discretionary
system that we have into two arbitrary divisions. That is what the Bill proposes, and that is why the distinction between the two parts of the process and the language is absolutely critical, as is understanding where the boundaries lie and whether they are in any way permeable or whether they are fixed. The technical detail to describe the infrastructure, contamination, substance or transport is not correct or appropriate. Perhaps the noble Lord, Lord Greaves, has got it right when he talks about development, because they are all aspects of development, but I ask the Minister and officials to think really hard about the proper language here.
The other issues that have been raised are about the flexibility, and we will come on to that in later amendments. What we have is a cliff edge at the end of the first stage on the three criteria, which are very blunt—location, land use and amount. The rest is about how it works. Unless we are clear that there is no way that anything that is discovered that cannot be known, because no site investigation will have been required—in many instances none will have been done—and unless we know whether there is any way in which to alter the PIP, or unless conditions are attached to the PIP, the only choice is to reject the planning application as a whole. The noble Lord, Lord Greaves, is quite right—that means that we may end up getting fewer sites agreed than under the present system. This is an extremely important set of amendments and some very important issues have been raised.
