Okla. Stat. tit. 19, § 19-339.4: Environmental remediation of land

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.
