Again, it goes back to the design of the contracts involved.
One of the considerations around the ownership of these assets is that it's going to be a near-monopoly. Given that's the fact, and the fact that private sector investors have an incentive to have risk-adjusted net revenues as high as they can to increase their profitability, there is an incentive on their end not only to increase revenues through increasing user fees, but also to drive down costs. That may include deferred maintenance, and that kind of thing.
At the end of the day, it comes down to how that contract is drafted, and what obligations the other owners of the asset have with regard to maintaining the asset over the long term.
