If Utah takes over the Federal lands the cost of managing wildfires will actually be much less then in the past. The State will sell off all the land to private developers, who will then take over the responsibility of managing their land. That is the point of the land transfer, it is to get the land into private ownership. Herbert is a real estate guy, and has received a large number of campaign contributions from real estate companies in Utah.
Just like what is happening in Montana and Wyoming, large tracks of land will be locked up in private ownership. Ranchers, Fisherman, and Environmentalists will no longer have the freedom of movement they currently enjoy over Federally managed lands. This transfer is a threat to environments, Ranchers, Hunters, and Offroaders alike.
