Why is the OH ion a catalyst in this reaction?

because it is not used up in the reaction. They way I determine which is the catalyst is by seeing if it starts as a reactant in the first step and remains a product in a later step.
Intermediates will usually be formed as a product and then canceled out as a reactant.
