Saint John shaken by another explosion at scrap metal recycler

As Saint John continues to deal withthe aftermath of Monday's fiery explosion at the Irving Oil refinery on the city's east side, some residents were shaken Tuesdayby another blast at the American Iron &Metal recycling plant on the west side.

Gary MacDonaldsays hewas working in his uptown waterfront condo, located across the harbour from the scrap-metal shredding and exportfacility, around 2:20 p.m., when hefelt "a dullthud" and heard his windows rattling.

He jumped up to look out his living roomwindow and saw a telltale plume of white smoke rising from the American Iron & Metal, or AIM, site.

"For me it is becoming kind of a normal thingand that's not a good thing," said MacDonald, who has witnessed several explosions at AIM in recent months, including a "significant"one on Sept. 14, which he described as sounding "like a stick of dynamite going off."

Tuesday's blast was "moderate" in comparison, he said, but similar to what he felt from Monday morning's refinery explosion, which sent flames shootingan estimated 30 metres high and sawat least four contractors treated in hospital with minor injuries.

"This is not right," MacDonaldsaid. "What do we do to address it and how can we address it in a reasonable fashion to satisfy everyone and protect the health and safety of residents?"

'Infrequent impulse noise'

Port Saint John, which is leasing its federally owned land to AIM, confirmed there was a "small explosion completely contained within the shredder" at around 2:22 p.m.

AIM's site manager Kevin Hughes described the incident as "an infrequent impulse noise that resulted from a contained single burst of pressure following the shredding of some material."

"AIM is conscious that the city is on high-alert following the unfortunate explosion at the Irving Oil refinery yesterday," Hughes said in an emailed statement.

We must find a new balance, where people can live, work and play here and not be negatively impacted by industrial activity.- Don Darling, Saint John mayor

"It is important to note that the equipment is designed to withstand the bursts of pressure and these burstsare not a threat to thepublic."

Saint John Mayor Don Darling, who learned of the blast throughCBCNews,said he was "disappointed" to hear there was another incident at the facility.

City officials met with port representatives last week "with a goal of developing a new path forward," he said.

"While we appreciate the industrial nature of our city, we must find a new balance, where people can live, work and play here and not be negatively impacted by industrial activity."

Port Saint Johncontinues to take thematter very seriously, said spokeswoman Paula Copeland.

Port officialsare working with AIMto develop "robust protocols in terms of communication with appropriate officials as well as the public," he said.

"In addition, all parties are aware of the urgent need to mitigate the impacts from AIM operations."

Darling has said he plans to have "focused discussions" with industry officials and review communications plans following a string of incidents in the city.

Other incidents include therelease of a mystery productfrom the refinery,and abutane leakat Irving Oil's Saint John East Terminal in January thatforced 65 people from their homes for days.

Irving Oil officials are still trying to determine the exact cause of Monday's explosion but believe it stemmed from a malfunction ina diesel-treating unit, which removes sulphur from diesel.

The company issued a statement Tuesday, saying "the refinery as a whole is safe and the specific site of the incident is isolated and contained."

The last "flare-up" or re-ignition occurred at 9 p.m. Monday, according to Saint John EMO officials.

No air quality issues have been detected and crews working on the "turnaround" maintenance project were expected to be back on the site Tuesday night.
