Don't be alarmed if you hear loud and unusual noises coming from the Marathon Refinery in Robinson.
Those who live around Robinson's Refinery will hear loud, short burts of sound coming from a noise canon right before and after dark, said Refinery officials.
The sounds are designed to safely deter birds from entering the refinery workspace, and the noise will not harm those birds in anyway, according to Marathon officials.
Marathon is encouraging those with questions, comments, or concerns to call (618) 544-2121 and ask to speak with Human Resources.
