Subject: FW: Town Hall Power issues update 20 January 2017
Hello,
Update on the power outage situation.
Was able to interrogate the Building Management System last night — the first leg of the power
went off at 4:02am on the 19th
Additional surge suppressors have been found to be bad — DPW and Purchasing have ordered,
expect to have some replacements onsite today, prioritizing financial operations for replacement.
Bad circuit breaker was found powering the server, Chris from DPW replaced this morning.
Server techs are onsite now — believe bad power supply found on server — still troubleshooting.
PCB contamination was found in the manhole — leaks from the failed transformers. Clean Harbors
had a hazardous material 'vacuum truck' onsite last night — they completed a full decontamination.
They found no contamination outside of the manhole, there was no danger of exposure to
residents or staff.
The Health Department may have lost some vaccines during the outage — they are confirming.
ACTION PLAN:
Transformers have been located in Boston — they are headed our way. Eversource expects to install
them today and has crews onsite to do that. They are waiting for transformer arrival and an
Eversource inspection.
They have a police detail onsite —Thaxter Street (incoming from Main) will be closed at various
times during the day.
The plan is to install the transformers today — then to make the switch over after midnight tonight.
The Town Hall, and Main Street west of the Town Hall, will be without power for approximately 1 to
2 hours. (i.e. midnight to 2:00am)
This is the plan as of 9:30am this morning— it can change — I will update later in the day.
Best, Ed

Mr. Driscoll,
Custodial staff left the Town Hall around 10:30pm on January 18th and all was in order.
When the DPW arrived to open the building on Thursday, January 19th at approximately 7:OOAM,
emergency lighting was on along with some of the buildings lights.
Eversource was immediately notified. They responded and were onsite within the hour. Preliminary
troubleshooting occurred upstream in the electrical grid (by the delta) and was determined not to
be the issue.
Eversource then focused the troubleshooting and found one of the two transformers that serve the
Town Hall had failed. At approximately 9:30am the second transformer failed and the building was
left without power.
Eversource provided an emergency generator and it arrived onsite around noon.
Main power to the building was restored around 2:OOPM.
For safety concerns power to Main Street west of the Town Hall was shut down for about 35
minutes.
One circuit in the server room proved troublesome and a work -around was implemented around
3:30PM to restore e-mail function. An electrical upgrade to this circuit will be completed by the
DPW on January 20th
Throughout the day the Town Hall remained open and available to serve the public as well as could
be done without computers.
The phones were down — messages could not be left.
The Town Hall, Library and Fire Station and Senior Center lost E-mail and internet access for the day.
Preliminary inspection of the transformers yielded no root cause — it was noted they were old.
Preliminary inspection of the Town Hall equipment had seven surge protectors damaged and will
need to be replaced, the heating system appears okay.
The Eversource provided generator is located on Thaxter Street between Town Hall and the library.
It is cabled into the Town Hall via a covered cable tray over the sidewalk. This unit will run 24 hours
a day until the transformers are replaced. A representative from Eversource or the generator
company will be onsite at all times when the generator is operating.
The transformers are located underground in the manhole at the rear of the Town Hall parking lot.
Standard operating procedure is to have Clean Harbors evaluate to confirm no hazardous
contaminants are present in the man -hole before replacement can begin. This is currently
underway.
Eversource is searching for a replacement transformer and need to have the Clean Harbors
evaluation completed and have a new transformer located before they can give a realistic time
frame for transformer replacement. The replacement may include expanding the size of the
manhole opening to accommodate the new transformer.
There will be a planned power outage after the transformer replacement is complete — expected
duration 1 to 2 hours. Eversource has been requested to provide advance notification of this — and
it was suggested that after hours or on the weekend may be a good time to complete this work.
A back-up generator to provide power to the Town Hall has been included in the CIP.
