Whenever an order is issued as a result of a public hearing under this chapter at the request of any person, a sum equal to the aggregate amount of all costs and expenses, including attorney's fees, reasonably incurred by that person, for or in connection with his or her participation in such proceeding, including any judicial review of any agency action, may be assessed against either party, as the circuit court, resulting from judicial review, or the Arkansas Pollution Control and Ecology Commission, resulting from administrative proceedings, deems proper.
