DANVERS — If you see flames and hear a strange sound in Danversport on Monday, don't be alarmed.
It's just crews dismantling a National Grid propane facility at 18 Broad St.
Before they can take the facility apart, workers have to purge any remaining gas in the system, and that will require flaring it from the lines. This work will take place during a normal day shift of 7 a.m. to 4:30 p.m.
"The flare will be evident by a visual steady flame and low-level sound," a notice sent to residents said. This is a routine procedure as the plant is taken off line.
"These conditions will not result in any hazards or emergencies to the adjoining properties," reads the notice sent to residents living on Bates, Riverside, Appleton and Broad streets and Rainbow Terrace.
The facility sits behind a small Danversport neighborhood just off Appleton and Broad streets, on property that also abuts adhesives manufacturer ITW Devcon.
National Grid has contracted with Costello Dismantling Co. of Middleborough and Eastern Piping and Engineering of Fall River to conduct the flaring operation at the station, according to a memo from acting fire Chief Kevin Farrell.
Farrell plans to send a recorded message to resident before the work begins.
The flaring operation is expected to take no more than two days and finish up Tuesday. The facility had been tested yearly but had not been used for five or six years, said David Graves, a spokesman for National Grid.
The facility had been used to inject propane into the gas distribution system on cold days when demand would cause pressure in the lines to fall. Improvements to the gas system in the area means the facility is no longer needed.
"It's being taken out and being decommissioned and removed from the property," Graves said of the facility.
