ON THE QUESTION
Mayor Donchess
| think Mr. Boucher ...?
Mr. Boucher
Yes thank you Mr. Mayor. I'll give you a little description of the energy recovery upgrades going on at the
Waste Water Facility. It consists of the installation of two brand new generators that have the capability of
burning both bio-fuel and natural gas. It is an upgrade to the facility because our previous generator only
burned biogas and (inaudible). But it is a very complex project; these generators will power our digester
complex at the Waste Water Facility. This is the part of the facility that treats the solids before they leave for
beneficial reuse. It powers generators, lighting, pumps, hot water pumps and heat exchangers. So it’s a lot of
power that this facility needs. Waldron Engineering is the engineering firm that designed the upgrades. They
also did the construction oversight. We would like them to continue with the construction oversight.
Unfortunately this project has gone longer than we had intended because of its complexity. There have been
some modifications along the way because we are trying to fit everything into an existing building versus a new
building. We have had issues with existing utilities, we didn’t know they were there. Some were underground,
some were under the concrete, so things had to be modified throughout the way. So we have exhausted
Waldron’s — they had to draw up new plans every time. We are nearing the end, we are at the punch list
phase, we do have some oversight. We did some testing today throughout this week. But Eversource has
required extra items before we connect to the grid. We have the capability if we generate more power than we
need, we can send it back to the grid for cost savings.
Also, the State has required some extra testing for the air permit. So we would like to continue using Waldron
who has been working well with us, oversee us through the end of the project which we are hoping will be done
within a month/month and a half. I'll answer any questions.

Alderwoman Klee?
Alderman Klee
Thank you Mr. Mayor. Mr. Boucher, you said that this one will burn biofuel and another fuel. | didn’t quite hear
that. By adding the other fuel source, rather than using a biofuel, there’s a cost savings with that also or just
gives us an alternate?
