Last one Mr. President, yes and the abatement | can understand that. Again, I’m thinking more nature erosion
time, five years down the road, ten years down the road.
Mr. Millan-Ramos On top of what we described already, there is also in consideration putting some sort of
wrip wrap in the existing edge of the river. We may or may not have figures showing that. We do? Do we?

We've had a company in Nashua that dumped a lot of asbestos and at one time it was considered darn good
fill, now we are more educated and stuff so | am not surprised it is around in our City. But from time to time it
shows up. Again, | know ask a lot of questions and one statement, but you didn’t touch base on the
monitoring, so what happens, is somebody going to come and make sure that none of this is getting exposed
or anything and who would be responsible for that?
Special Bd. of Aldermen — 10/26/15 Page 16
| think the first we’ve got to do is decide are we doing this or are we getting on the NPL? | mean that is a fairly
simply straight-forward decision. Then the second thing is to go ahead with understanding some of the costs
and what the City can bear in terms of what we get as a solution versus what we invest in it.

And as | understand it, the TIF was to clean up the asbestos portion of this and do the interchange with Broad
Street Parkway?
Ms. Taylor I’m not clear on the details on that, that is really between the City and the developer but we do
understand that the developer will be looking to get some level of a TIF and | don’t know to the extent of that.

President McCarthy
| know that not everybody on the Board has been at all of the meetings and there is a $25 million cost
differential there that we are talking about.
Alderwoman Kelly
If you were going to remove it would only be on Mohawk is that correct? So if we went to full remediation it
would not include those other two sites that you were talking about?

impermeable cap similar to what we would put here but not encapsulated it. So those are the tannery waste.
But with this case of depleted uranium that we were trying to contain that was leeching into the groundwater,
we are going to be putting a wall around that to inhibit groundwater flow.

But an excavator wouldn't?
Ms. Taylor it is not as precise is what I’m saying. It’s not even that it would come up next to the sewer line but
that if you have a big open space right next to that, the potential for that to collapse, to break, is much greater
than if you have one small part that is being, one secant pile is being drilled.

What about on the bottom? What on the bottom is going to stop it?

Ms. Taylor That capped area would be basically open space for anybody that was living there if there was
such a development that could be walked on and used for open space. There wouldn't be any structures that
would be built on that.
Special Bd. of Aldermen — 10/26/15 Page 9
Ms. Taylor | would say that is more likely if you remove it than if you built the secant wall.
Alderman Dowd
| don’t think some of the people here have heard your explanation of the approach that you are tending to use
and | think if you explain how you are going to contain that area and address the potential of not having leaks
and all of that and how it is built will probably answer a lot of questions that you might get.
