If a preliminary review of a budget plan has been obtained under subsection (d), then the Remediation Applicant may submit, with the application and supporting documentation under subsection (b), a copy of the Agency's final determination accompanied by a certification that the actual remediation costs incurred for the development and implementation of the Remedial Action Plan are equal to or less than the costs approved in the Agency's final determination on the budget plan. The certification must be signed by the Remediation Applicant and notarized. Based on that submission, the Agency is not required to conduct further review of the costs incurred for development and implementation of the Remedial Action Plan, and it may approve the costs as submitted. Within 35 days after the receipt of an Agency letter disapproving or modifying an application for approval of remediation costs, the Remediation Applicant may appeal the Agency's decision to the Board in the manner provided for the review of permits under Section 40 of this Act.
If the Remedial Action Plan is amended by the Remediation Applicant or as a result of Agency action, then the corresponding budget plan must be revised accordingly and resubmitted for Agency review.
The budget plan must be accompanied by the applicable fee as set forth in subsection (e).
The submittal of a budget plan is deemed to be an automatic 60-day waiver of the Remedial Action Plan review deadlines set forth in this Section and its rules.
Within the applicable period of review, the Agency shall issue a letter to the Remediation Applicant approving, disapproving, or modifying the estimated remediation costs submitted in the budget plan. If a budget plan is disapproved or approved with modification of estimated remediation costs, then the Agency's letter must set forth the reasons for the disapproval or modification.
Within 35 days after receipt of an Agency letter disapproving or modifying a budget plan, the Remediation Applicant may appeal the Agency's decision to the Board in the manner provided for the review of permits under Section 40 of this Act.
The application fee must be made payable to the State of Illinois, for deposit into the Hazardous Waste Fund. Pursuant to appropriation, the Agency shall use the fees collected under this subsection for development and administration of the review program.
