5 Pa. C.S. § 917
An application for a permit or license shall be verified and shall be accompanied by a nonrefundable application fee in an amount established by the commission by regulation, which fee shall be subject to review in accordance with the act of June 25, 1982 (P.L. 633, No. 181), known as the Regulatory Review Act. If the revenues generated by fees and civil penalties imposed pursuant to this subpart are not sufficient to match expenditures over a two-year period, the commission shall adjust those fees by regulation, subject to review in accordance with the Regulatory Review Act, such that the projected revenues will meet or exceed projected expenditures. If the department determines that fees and civil penalties established by the commission are inadequate to meet the costs of minimum enforcement efforts required by this subpart, then the department, after consultation with the commission, shall adjust the fees or civil penalties or both by regulation, subject to review in accordance with the Regulatory Review Act, such that adequate revenues are raised to meet those costs.
