A. County commissioners may use county funds and resources for environmental remediation of land, including land owned by public trust authorities, if the Department of Environmental Quality certifies, in writing, that the property is polluted or contaminated to such degree that remediation is necessary to restore the environment. Remediation of the contamination or pollution shall be pursuant to a remediation plan approved by the Department of Environmental Quality.

B. Unless the Department of Environmental Quality determines that it is unnecessary under the circumstances, the remediation plan shall include a component describing erosion control and revegetation measures to be implemented. The remediation plan shall not be approved until the erosion control and revegetation measures have been certified as appropriate by the local conservation district.

C. The county may seek reimbursement for its remediation costs and expenses from state or federal monies or other sources, if any are authorized and available for such purpose.
