North Tonawanda Mayor Arthur Pappas said the leak was minor and completely contained to the facility.

Pappas said crews were replacing a chlorine cylinder when one of the seals did not function properly, releasing a small cloud of chlorine gas.

Pappas said no one was injured and the public was not in danger.

As a precaution, River Road was closed to traffic during the investigation, and residents were advised to close their doors and windows.
