Tampa-Port of Tampa officials on March 17 approved spending $17,150 to repair a faulty siren designed to warn the port and nearby neighborhoods of an accidental ammonia release. Repairs to the siren at Kinder Morgan and Yara North America in the Port Sutton area will take about a month, according to local press reports. The siren is one of four at the port. The other three sirens, on Davis Islands, Palmetto Beach, and Hookers Point, are in operation.
