A fire early Wednesday morning at a Black Rock metal manufacturing plant released soot into the air, leaving residue on vehicles and buildings in the area, according to the state Department of Environmental Conservation.
The blaze happened at Aurubis Buffalo on Sayre Street, formerly Luvata, near Military Road and Hertel Avenue.
The material that was released, which the DEC called soot, or inert carbon, was sampled and sent to Albany for testing.
The agency sent staff from its spills and air resources divisions to the scene to "assess the situation and meet with plant officials."
"No significant environmental impacts are anticipated as a result of the release," the agency said in a statement. "Company officials have told DEC that they are working with community members to clean up the areas and vehicles affected by soot."
It could not immediately be determined when the fire occurred.
The city fire department did not respond to the scene, according to a dispatcher.
Company representatives could not immediately be reached to comment.
