MONTVILLE, Conn. (WTNH) — Crews responded to the scene of a major blaze at a scrap yard in Montville after a fire broke out Wednesday morning.

Firefighters faced several challenges after flames erupted in a scrap metal pile on the Pequot Road property. Crews asked Montville residents to avoid an area on Pequot Road due to an excess of smoke and fire.

“I’ve been here 18 years and this is the second time it’s happened in two years so it gets concerning,” said Pequot Road resident Kerry Dougherty.

The pile of burning debris soon grew to nearly a hundred feet long, fifty feet wide, and sixty feet high with the smoke and smell of burning metal and car parts traveling as far away as East Lyme.

“I heard people up the hill had to leave their homes because the smoke was so bad,” said Dougherty.

DEEP arrived on the scene and monitored the air quality which tested at safe levels. Still, residents were told to keep doors and windows shut. The CT Department of Energy and Environmental Protection also monitored what was running off into a nearby river.

“It’s mostly petroleum which is a good thing. It floats up on top of the water. It’s easy for us to catch,” said Rich Scalora, an Emergency Response Supervisor with the DEEP.

More than twenty fire departments from both Connecticut and Rhode Island helped in this effort. The water had to be trucked in because there are no fire hydrants nearby.

“It’s actually well coordinated,” said Barnes. “The tankers come in one way. They drop their water into the tanks. It’s a constant flow process.”

Workers from the scrapyard also assisted by removing the burning debris from the pile.

Part of the reason this fire was so hard to get under control is that a pile of scrap metal was so dense they had to pick up pieces to get to the flames below.

Kerry Dougherty and her kids had to stay home today because buses could not get down Pequot Road and she couldn’t get out of her driveway because of a fire hose across it.

“I didn’t get to go to work,” said Dougherty. “We have Thanksgiving deadlines but clients have to understand.”

Firefighters had the fire under control by mid-afternoon but fully extinguished the fire Wednesday night.

Police said no injuries were reported.

At this time, the cause of the fire is unknown.
