If he didn't get it approved he's liable for some serious fines, especially considering he may be running this thing under some highly built up areas and depending on the depth, could adversely affect existing construction, which would have to be planned for, he has to plan ventilation, service tunnels, lighting, fire control, emergency evac, etc, etc. Honestly it's a really stupid idea. I mean Seattle tried to dig a new tunnel and they got the TBM stuck for two years because they hit preexisting construction remnants and damaged the cutter. I don't know how this guy makes his money, but the way he spends it is fucking absurd.
