Second Ave. subway rock. Where is it going?

An article in the New York Times shows a lot of rock being removed from the Second Ave. subway excavation. Every once in a while, something interesting turns up in the Manhattan bedrock. Does anyone know where this rock is being dumped and whether it is accessible?

There are a number of contracts. Go to the MTA website and you can get the alignment information. However, the vast majority of muck bveing produced is by Tunnel Boring Machine, using disk cutters. The chips produced are all pretty uniform at 3"x2"x1". No crystals of interest in there...
