(2) any out-of-pocket expenses incurred by the commission in the particular proceeding; and
(3) when the investigation or hearing relates to a violation of a provision of this chapter, a regulation adopted under this chapter, or an order, stipulation, or term of a permit issued by the commission, the costs of any time devoted to the investigation or hearing by the commission staff.
(b) The commission shall provide an opportunity for any person objecting to an allocation to be heard before the allocation becomes final.
