Alderwoman Melizzi-Golja

Yes thank you and | guess that’s my concern. If 5 people have the same question, you only need to hear it
once. But people also need to know there is a process to exchange information.

President McCarthy
Work it through Sue and we will get answers.
Ms. Dumville That is what we do so we are happy to answer any of your questions.

Alderman Lopez

Special Bd. of Aldermen — 10/26/15 Page 25

In this case, we do just want to make clear tonight that without the support of the City, we don’t intend to move
forward in this direction with the developer. Like Melissa said, we want you to understand that this is a really
unique situation, this isn’t something we see all the time. We want to make very clear to you that this is, and |
hope we’ve done that tonight, that this is addressing more than just the Mohawk Tannery Site. It is addressing
these other parcels that otherwise would go untouched by EPA.

Special Bd. of Aldermen — 10/26/15 Page 24

other highlights here which are impacted, small impacted areas. The plan is to consolidate everything down
into the lagoon area, so essentially the three sites after will have no impact such that residential use could
occur. So it is really to get everything down to the smallest area possible where there will be a use restriction
and monitoring wells and deed restriction and keep it there rather than having it housed across the property.

Special Bd. of Aldermen — 10/26/15 Page 23

Ms. Taylor Yes you absolutely will get a response. Our process is to respond to the comments when we issue
the action memorandum, it is usually an appendix to the action memorandum which is a decision document.
And all of those questions and comments will be answered as part of that document.

Mr. Solomon That's all the questions | have, thank you.
