Alderman Lopez

And just to clarify, PPhos is in that too or is that...

Noelle Osborne, Plant Operations Supervisor

PPhos is everywhere. So that's not anything that we have regulations on yet PPhos but the Class V biosolids we have
at the wastewater facility and anaerobic digester which takes some of those pathogens and those viruses out of the of
the product. It reduces the volume. It reduces the odor. That's why you don't have a lot of odors from Nashua’s
wastewater facility. It is a heavily regulated. It's trucked off site. Usually the farmlands are in the northern part of the
State. Class B tends to go to crops that animals would eat not people. So there's that level. There is further treatment
that we could do Class A that we're currently exploring and that would be a product that, you Know, you could come pick
up at the wastewater plant and spread in your gardens. It's pretty inert at that point. Merrimack does that. Residents

are able to come and get that Class A biosolid from them, but we're not there yet. We're at Class B so phosphorus yes
is a non-renewable resource and its black gold for those farmers that are using it.

Alderman Lopez
| just want to dispel any rumors that were sprinkling or poo on orchards or whatever
Alderman Jette

So there's the stormwater - | understand we try to separate the stormwater from sewerage. Does the stormwater go
directly into the river or does that get treated?

Dave Boucher, Wastewater Superintendent

Some stormwater goes to the river and is not plumbed into the wastewater facility. But the ones that is in the combined
system or the sewer system that has just storm water will come to the wastewater facility and be treated. It's not
separated at the facility. It’s treated just like its sewage.

Alderman Jette

Okay, so how much of it goes directly into the river?

Dave Boucher, Wastewater Superintendent

I'm not sure of a percentage that goes to the river direct.

Alderman Jette

And the EPA is okay with that? We're okay doing that? | understand that stormwater it's not just pure rainwater. Its
water that's gone over the street, picked up oil, and other pollutants and so it raises the question, in my mind, why would
we be allowed to dump that directly into the river?

Dave Boucher, Wastewater Superintendent

| believe that was a decision made by the city to not separate but build a wet weather treatment facility, which would
allow us to take in as much as possible and treat. There are some outlier areas where it's not feasible the plummeting
currently to the collection system.

Lisa Fauteux, Director of Public Works

No, | don't think - let me let me take a stab at that Dave. | think what Alderman Jette is saying that why isn't all of the
stormwater being treated that's going to the river, correct?

Alderman Jette

Correct.

Special Board of Aldermen 10-14-2021 Page 21

Lisa Fauteux, Director of Public Works

Yeah, so that's something that we think is coming down the pipe and it's something that communities who have fully
separated as Manchester is doing is going to have, we believe, will have significant problems because it will end up
having to treat all of those stormwater outfalls. That's one of the advantages of our system is that most of the stormwater
is going to the treatment plan and being treated and so that's why we are reluctant to separate the entire system. Only
the areas that we absolutely need to where we're still having CSO overflows. So that's the way we've approached our
wastewater system. So | think you're correct. | think that eventually that's going to be a major problem for a number of
communities who are fully separated. Right now it is not though, the EPA is allowing us to just discharge.

Alderman Jette

So if the stormwater that is treated, why do we separate that?

Lisa Fauteux, Director of Public Works

We don't separate it. It's altogether. It's a combined system.

Alderman Jette

Okay.

Mayor Donchess

C | add to that? My impression is that for a while the EPA is, you know, main thrust was to get communities to separate
because, you know, cities on the East Coast - these older cities - most of them were separating. The problem with that,
as you've just mentioned, is that you get stormwater untreated and untouched going into the rivers. So now, you know,
there may be some problems with that approach given the stormwater and so a lot of our stormwater is being treated,
which is kind of unusual, actually. | believe most of the cities have separated like Manchester. So | think over the years,
you know, there was some separation but then this wet water idea hold the water and then run it through the treatment
plant was developed and most of the stormwater runs through that system but not all of it. Now if any of that is not
accurate, which it may not be, so let's see. | think it's correct.

Lisa Fauteux, Director of Public Works

Yeah, you’re correct.

Alderman Jette

So | guess, you know, the message is that eventually all of the water whether its stormwater or sewerage is going to
have to be treated before it goes into the river. That's in the future for us.

Lisa Fauteux, Director of Public Works

We can't answer that for certain. | wouldn't speak for the EPA, but we believe so.

Dave Boucher, Wastewater Superintendent

There are more and more stringent regulations. They seem to get more and more stringent and stormwater is certainly
an area they're looking at. You have an MS4 Permit now that monitors stormwater outfalls. That's just taking hold now
in a lot of different urbanized communities. Those plans to stop monitoring your outfalls on stormwater and you know, as
the regulations get more stringent, more stringent, you know, it leads you to believe that, you know, treatment of
stormwater is down the road but to be seen.

Alderman Jette

Okay, thank you.

President Wilshire

Anyone else?

Special Board of Aldermen 10-14-2021 Page 22
Alderman Schmidt

Thank you. Can you talk a little bit about lining of the old sewerage pipes instead of replacing?

Dave Boucher, Wastewater Superintendent

Sure. So that's part of the CMOM program that the city is undertaking and a lot of that starts off with an inventory of all
the city's assets with respect to its sewer infrastructure through TV tapes and cleaning of those lines. Then what we do
there, similar to the paving program, is we score the pipe. So we're able to identify cracks and, you know, breakages
and basically it allows you to look at the pipe. Is the pipe good enough to be salvaged for a liner or it is it too far gone
and need to be replaced? So it turns out to be a mixture. We try to line as many pipes as possible because look at the
benefit you get for lining. You’re not digging up the street. You're salvaging the existing infrastructure and you're putting
essentially almost what winds up to be a hard plastic liner in your pipe that's going to last, you Know, years on years on.
So does that answer your question?

Alderman Schmidt

Yes, follow up. So that's one of the problems we see between paving and all of the underground work that needs to be
done because we count on you to do that art before we can even get to the paving part.

Unidentified Male Speaker

Certainly and, you know, we've done CMOM programs in Manchester. The coordination between paving and trying to
do is particularly if it's a pipe replacement, the coordination with the paving program has to be kind of intertwined.
Because as Dan said, these cities also have five year moratoriums, you know, so if you're paving Main Street but you got
a pipe replacement on Main Street, you better know about or its five years down the road before you're going to be able
to do that.

Alderman Schmidt

And so some areas of our city are very old as far as the pipes that are there. Some of the streets downtown are simply
being patched, and replaced, and fixed because of this weight that we need to do. Is that right?

Dan Hudson, City Engineer

Sure. Engineer Hudson. Yes, that's true. We do differ paving, do some Band Aid type treatments on some roads that
for whatever reason can't do the sewer at that time and need to do it later. But as noted, we are doing as much lining as
we can. We find it about 20 times less expensive than doing the full dig replacement and much less disruptive. So we
have prioritized the system. We're looking at the older pipes of the system and pipe materials. Pipe materials have
changed over time. So we're focusing our effort on the ones that we've seen historically we’ve had more problems with
so we have a good effort and it is tightly coordinated with the paving program. As Engineer Saunders said earlier, ideally
the paving should be the last thing but that's not always possible but that is what we strive for.

Alderman Schmidt
Great. Thanks so much.
Alderman Klee

Thank you, again. | guess | have a question as far as the scoring is concerned. Do you like the paving project - don't
always necessarily do the worst ones right away. You try to get to those ones that are in the middle before they
completely break down. So for instance, | know Orange Street | think they went into do a lining when they got in. They
realized it was a lot worse and they had to, | think, do a lot more replacement or at least some of that to that extent. It
took longer than was expected but for the most part when you're doing this scoring, again like the paving project, do you
try to get in and take care of those before they get so bad versus going in and prioritizing those that are already bad?

Dan Hudson, City Engineer

Yeah, we do - it's a little bit different I'd say because, you know, for roads in bad shape is still passable, still usable but if
a sewer pipe collapses, you know, has a major issue, it's not usable and creates quite a problem. So it's a little bit
different. As we're doing the TV work when we find collapse pipes, we try to fix those as quickly as we can. But then we

Special Board of Aldermen 10-14-2021 Page 23
are trying to line pipes and line as many as we can to catch them before we have that type of an issue.
Alderman Klee

Just a quick follow up. | just lost my train of thought sorry about — age. | guess the question that | have is we talked
about those that could possibly collapse and so on, do we know when something like that happens? Does it create a
sinkhole? How do you know that it’s collapsed or are you pretty well versed that this one is on its way out?

Dan Hudson, City Engineer

Well through the TV work, we can see what the issue is. Yeah lots of times we don't know there is an issue in a pipe and
a sinkhole leads you out there's something going on here. Sometimes maybe that's a drainage issue or other things but
sometimes it's a sewer issue. So if we respond to one of those conditions, we start digging and find and address
whatever the problem may be. But we are finding problems as we do the TV work so there's a reason we're doing it and
that's why we want to find pipes in good condition but we also want to find the ones that aren't in good condition so that
we can address those.

Alderman Klee

Just one quick other comment. Being the Ward Alderman of one of the oldest sections of this city - the north end French
Hill area, | do see that you go in and do work. Again, it seems like it’s extended. You dig up one part and then come
back a little bit longer and so on. Is that because when you get in there you realize you need a part that isn't - in other
words, you can't finish it all at once. It seems like Manchester Street seemed to take a little bit longer and I'm pretty sure
that was a sewage issue as well - where Mount Pleasant and all that area is. So was that the kind of case that you
would have? Orange Street seemed to take a long time as well.

Dan Hudson, City Engineer

Yeah it does take a long time. | mean you're working in and around the utilities. Paving or paving on top of them but
here with the sewer work, you’re digging right in amongst them, right. So it has to be slow and methodical work so that
you don't do damage to those other facilities. Lots of times it's challenging because a lot of the oldest sections city we
don't have records. We don't know where a house’s sewer connection connects to the sewer main sometimes or where
it goes, you know, from the sewer main to their house. Sometimes they have multiple pipes and we don't know that so.
You never know what you're gonna find until you start digging but you run into challenges, and you deal with them, and
so sometimes things are evolving. You might go on with a plan and sometimes the plan has to change so that may be
why we have to come back sometime to do different things.

Alderman Klee

So at least digging up helps you remap things later on. Thank you.

Alderwoman Lu

Thank you. Just a couple of really quick questions if | could. CSO is that combined sewer overflow? Its sewer and

stormwater? Alright. It’s when we combine the stormwater into the sewer? Okay. So when that is actually sent out into
the river, there's sewage put into the river at that point?

Unidentified Male Speaker
Very diluted.

Alderwoman Lu

Did | hear what?

Lisa Fauteux, Public Works Director

Very diluted.

Special Board of Aldermen 10-14-2021 Page 24
Alderwoman Lu

Did we have more CSOs before and then we reduce them?

Unidentified Male Speaker

Yes.

Alderwoman Lu

Okay.

Unidentified Male Speaker

Significantly.

Alderwoman Lu

Okay. How did we reduce them did we divert the stormwater somewhere else?

Unidentified Male Speaker

So that the city undertook a number of wastewater infrastructure projects as part of their original long-term control plan
that included a wet weather facility at its plant which takes a significant amount of wet weather and treats it. Also a
screening disinfection facility on the Merrimack River for CSOs 5 and 6 which also has up to a million gallons of storage
and anything over that will overflow into the Merrimack but it is disinfected and screened. We did a number of fine tuning
of the system by increasing capacity of pipes to get more flow to the plant. That's pretty significant.

Alderwoman Lu

And | may have asked this before but did any of it go to say like, Salmon Brook?

Unidentified Male Speaker

Salmon Brook - | think that CSO was closed. That’s CSO 2.

Unidentified Male Speaker

Yeah. No, we haven't had any discharge.

Unidentified Male Speaker

No, not the Salmon Brook.
Alderwoman Lu

Okay and just one other question | had is CMOM. Is that an acronym for a couple of different things?

Unidentified Male Speaker

Yes. It's an acronym for capacity management, operation, and maintenance. It includes basically, like | said before,
CMOM program for your collection system will include inventory and TVing all the assets, cleaning them, scoring the
pipes, and then basically determining which ones can be lined and which one can be replaced. You do that as you go
through the entire city. So you're able to, you know, basically make improvements on a year by year basis. You know, it
doesn't happen overnight. If you think about how many miles of sewer you need to TV, inspect, score, and then have a
capital improvement project to now to correct those deficiencies based on the number of miles of pipe that you have. So
it's a long-term process but as you get into it and you go through it, then you become more and similar to the paving
program in a maintenance mode as opposed to a reactive mode. So then you're keeping up with your system. It's
anticipated that, you know, sure pipes age as you go along and they'll need to be fixed, but as you go through the
program once, which is your biggest kind of expenditures because you haven't done anything of that significant
magnitude, once you've gone through all your pipes, it becomes significantly less expensive because you've fixed all

Special Board of Aldermen 10-14-2021 Page 25
those problems and you've kept up with it.
Alderwoman Lu

Okay, thank you. Just a follow up. So do we sometimes use that phrase as shorthand when we talk about actually
spraying that stuff on the inside of the lines to preserve them? | thought they called that CMOM?

Unidentified Male Speaker

You mean like a liner? Well that’s CIPP. That's secured in place pipeline.
Alderwoman Lu

| was just mixing up the two.

Unidentified Male Speaker

Yeah it’s a different acronym.

Alderwoman Lu

Okay, thank you. They both start with “C”. Thank you.
Alderman Caron

Yes, thank you. So since this facility is in Ward 7, | first want to thank you for taking the time to in the last four or five
years, doing all this maintenance and catching up because you were lacking on some of that. | know it was a lot of
money but as the Mayor said earlier, people rely on the wastewater treatment plant. But if it goes down, it doesn't just
affect one or two people, it affects the city as a whole. So | think this is really a good way to proceed and | like that idea
that you're going to review this every year annually — rates. Doing increases can be very hard and difficult specially for
seniors but if you set it up So that the increments are a little bit lower over a long period of time, | think people will accept
that as well. | probably could have answered my own question but with all these regulations that EPA sends down, do
they ever send you any money?

Unidentified Male Speaker
No.

Alderman Caron

You know it's wonderful to make these mandates and | understand that, you know, because you want a cleaner
environment and you don't want this going into why rivers and streams but people also need to understand that these
communities need help in being able to do this work. So | think that's great. In talking about infrastructure, Harvard
Street had a major breakdown. | think it was a year or so ago and that street was closed until you could get it because
you didn't realize how bad that pipe was over there. So kudos to you. | don't envy your job. I've been there plenty of
times but | think it's important for the community to Know that this is very important and vital like the Police and Fire
Department to our community. So whatever you need, people have to understand that it's not frivolous. It's very
important to the community but thank you so much. | appreciate it.
