Crews from the state Department of Energy and Environmental Protection responded to the Naugatuck River near downtown Seymour to investigate the cause of a sheen that was seen on the river yesterday and said it appeared to be from a small one-time release.
DEEP said they were looking into the source of a petroleum discharge that pooled up around the fish ladder in downtown Seymour and determined that this was not a significant ongoing issue.
Crews have left the scene.
