Around 4:30 in the afternoon, the Derby Fire Department was dispatched to a report of a brush fire in Osbornedale State Park off of Route 34. On arrival, companies found a rapidly moving brush fire heading up the hill and potentially threatening the Kellogg Environmental Center at the top of the hill. Mutual aid was requested from Shelton, Seymour, Orange, and Ansonia. Companies were able to stop the spread of the fire before it reached the large field of grass beyond the forest. The fire was placed under control around 5:20pm.
