mr. moscovitz over the tells us he doesn't like surprises, but i have one for you. we do not know the cost of the central subway, and there is no way of knowing until the boring starts. the reason for that is this project is below the water table, next to the day. there will be ground water, and the watering plan is to use pumps. those pumps have a capacity, and if they get overwhelmed, that bore will have to be sealed from two aunts and pressurized with thousands of pounds per square inch in order to keep the water out. what that means is that workers will sit for three hours a shift in compression chambers in order to enter the excavation. the cost of that is enormous. it can be done, but it is enormous. it is something that could happen. proponents say that it will not happen. i am advocating you get someone from the east coast who has nothing to do with this project and ask them the question -- will pressurization have to occur? if it does, we will be stuck with the bill. supervisor campos: thank you. next speaker please. >> i am the chairman of the central subw
