OMAHA, Neb. (AP) — An arbitrator has ruled that Omaha must deploy more firefighters and medics because the city’s response times don’t measure up to national standards.

The arbitrator ruled last week on a July 2013 grievance by the firefighters union. The union says the city violated a contract provision that says the city should try to meet the national standards.

The arbitrator also says city officials must write a report identifying deficiencies in response times throughout Omaha.

Mayor Jean Stothert (STAH’-thurt) says the city will appeal the arbitrator’s rulings.
