The fire extinguishing system at the Vineyard Transit Authority gas pumps in Edgartown discharged over the weekend, releasing hundreds of pounds of a fire suppression powder onto the lot. The cause of the discharge is still under investigation.

Edgartown fire chief Alex Schaeffer said the call came in at 1:23 p.m. Saturday.

“All of the extinguishing agent had been discharged from the nozzles, so there was a white powdery substance being aerated by passing winds,” he said. There was no fire.

Mr. Schaeffer said he notified the Massachusetts Department of Environmental Protection (DEP. He said he was informed by VTA general manager Angela Grant that the lot is on a catch basin called a tight tank. They used a pumper to rinse the powder into a drain.

“It wasn’t part of a drainage system going into a wetland or the ocean,” Mr. Schaeffer said.

Edgartown police chief Bruce McNamee said security camera footage is being thoroughly reviewed.

“As far as we know, someone didn’t physically do it,” he said.

Chief McNamee also reported a car accident in the area of 127 West Tisbury Road on Saturday evening at 7:45 p.m. A 31 year-old Oak Bluffs man reportedly left the roadway, traveled 75 yards before crashing through a split rail fence and traveling another 25 yards to collide with the side of a house. The chief said the damage to the house was minor and the man was transported to the hospital with non-life-threatening injuries.

He said it appeared the driver had lost consciousness due to a medical issue.

In Tisbury, police reported three OUIs over the weekend.

Det. Max Sherman said Tisbury police have printed good deed cards for children they find making good choices, like wearing a bicycle helmet. The cards come with rewards from participating Vineyard Haven businesses.
