Honestly, despite getting away with some of the pitfalls you'd have by having a actual human manned search inside a active site, I still don't think he'll get the permission required. The environmental experts would have a field day with the local council, and they'd likely find themselves in hot water. So, while he's doing the right thing in suggesting he would look to improve the local area by investing in it from the Bitcoin on the hard drive, there's just too many variables, as well as health, and safety.
My first thoughts when this started all those years ago, is he'll never get permission for a number of reasons, but one that really stuck out was the health, and safety violations. For example. it's an active site, and could potentially have unwanted sharp objects, which they'd never be able to give permission to someone to look through it, knowing that there's a good chance that they could get seriously hurt.
So, going the robot route is a good idea, it reduces the risk of injury, and death, plus no one actually needs to be on site. However, there's still issues with disturbance of the debris, which would create a environmental hazard, at least that's what the local council have in mind.
Plus, this is all hearsay remember. While, this man's case might be genuine, he can't prove that A) these funds exist B) They'll still be retrievable, and C) he can retrieve them without causing any disturbance or health hazards.
Plus, it really does open a can of worms if the council did open it up for him to search, since all sorts of people could claim to have lost something. Unfortunately, he's probably never going to obtain that hard drive legally.
There was an update to this story a month or so ago where the person who lost the hard drive must already be infact rich.
That he has plans to have some sort of robots that are more like drones built so they can scan the garbage field in England for the missing drive.
That to me that is going to cost him as much as the coins are probably worth from where the markets stand right of now.
I don't think he was rich, not overly so anyway. I guess that's whatever you deem
rich is, he obviously had a decent job being a computer engineer. However, I would think he has made money from the publicity, I mean he has some fairly successful presenters doing a sort of documentary on him, and I'm assuming that wasn't done for free, since stories are sold all the time. Plus, the numerous other stories which have developed along the years. Pretty much everyone in Wales knows this story. Also, and don't quote me on this I believe there's been public fundraising done, as well as likely private investors which have gotten involved in the project. In one of the articles above he says the funding has been secured, therefore the people involved in the proposed project are all likely getting a share if it was ever found.
Just to correct you there too, Newport is in Wales, not England.
