The best suggestion is to remove the tree, as there is no home treatment and it would be expensive to have a professional treat it every year. This rust needs a nearby juniper plant to complete it's life cycle, so if there is a juniper in the vicinity, that is your other vector of the disease.
I'm so sorry this is not better news, but this is a new disease in the last 10 years here in Oregon and there just hasn't been a cure yet.
