The Department shall adopt rules setting minimum and maximum filing fees under this chapter. A nonrefundable filing fee must be paid at the time an application is filed with the Department. If the approved capital expenditure or operating cost upon which the fees were based is higher than the initially proposed capital expenditure, then the filing fee must be recalculated and the difference in fees, if any, must be paid before the Certificate of Need may be issued. 22 M.R.S.A. Sec.337(7).
