The levy is going to be capped to protect landowners from cost overruns, because we all know, after years of experiences and many sad instances, that too often the budgeted and contracted price for much of this important infrastructural spending, when it comes to the end and it's installed and completed, there are often significant budget overruns. This legislation means that that debt is going to be ring-fenced, that it will be capped so that the people that are contributing to the funding and who are going to benefit know what the quantum is going to be and they know what their liability's going to be, and that's a very good degree of certainty that they are provided with.
