Ther are no lockers at the Omaha but station. Like he said when you go in you will have to show your ID
The same way you would for any other ticket, when you go in, to the right will be the front desk. Tell him your name, he may ask for identification so please make you have that on you, and he should have it. As for lockers, they have none... If you're talking about the bus the have regular compartments for carry-on luggage. But they aren't lock-able though.
