What about on the bottom? What on the bottom is going to stop it?
Mr. Millan-Ramos | wanted to add the geologic material that is right now at the very bottom, it is what we know
as till, it has a very, very low permeability, meaning rate of liquid going through it. So if anything, we are
improving what is already there. We are containing it laterally and vertically we are putting a cap on the top.
So we are essentially making sure that rain or flooding will not wash that out to the river. In all these years that
we have been testing the groundwater, we have not seen contaminants moving towards the river. So we don’t
have any reason to believe that it would be any different. If anything, it would be better, would be more
protected with this containment unit around it.
Alderman Jette
| have another question, the original owners of the Mohawk Tannery and its successors, | think Chester Realty
was the name, is there no source of money there to help pay for this?
Mr. Millan-Ramos Well there is a very, very minimal source of money. There was a settlement that was done,
an agreement between EPA and the Chester Realty Trust and it is money that has been used for investigation
of the site and other emergency activities as well. Right now, | don’t know the exact figure, but the last time |
saw it was $600,000.00 or something like that.
Ms. Taylor Which we would contribute.
Mr. Millan-Ramos We would contribute whatever remains towards the clean-up. Does that answer your
question?
Alderman Jette
Yes thank you.
Alderman Lopez
| just want to clarify because | have been misunderstanding this, comparing the risk of storing this in perpetuity
under like basically the cover you would get on a fancy meal, that’s one set of variables and the other one is a
removal event where for a period of time you need to focus on safety, transport, removal and all that kind of
stuff, the main factor is excavation? Because it seems to me that shooting a bunch of tubes around a circle
has the same risk of puncturing any kind of pipe leading in or out if you are not making sure you know where
everything is, that digging it up and removing it would have.
Mr. Millan-Ramos I’m not totally sure | understand your question.
Ms. Taylor The sewer line?
Alderman Lopez
You referenced the sewer line.
Ms. Taylor We have the drawings from the City we know exactly where the sewer line so we wouldn't ...
