A certificate of approval shall be issued for all dams and mine tailings impoundment structures, new or existing, upon a finding that the dam or reservoir is safe to impound water or the mine tailings impoundment structure is safe to impound mine tailings slurry within the limitations prescribed in the certificate. Upon written request by an owner for a certificate of approval, the director shall within fourteen (14) days inspect or cause to be inspected and issue a certificate if he finds that the dam, reservoir or mine tailings impoundment structure is safe to impound water or tailings slurry within the limitations prescribed in the certificate. Pending the issuance of a certificate of approval, the owner of a new dam, reservoir or mine tailings impoundment structure shall not, through action or inaction, cause the dam or reservoir to impound water or mine tailings impoundment structure to impound mine tailings slurry.
Each certificate of approval issued may contain such terms and conditions as the director may prescribe. The director may revoke any certificate of approval whenever he determines that the dam, reservoir or mine tailings impoundment structure constitutes a danger to life and property. Whenever he deems such action necessary to safeguard life and property, the director may also amend the terms and conditions of any such certificate by issuing a new certificate containing the revised terms and conditions. The owner of a dam, reservoir or mine tailings impoundment structure for which a certificate of approval has been issued shall not, through action or inaction, cause the dam or reservoir to impound water or mine tailings impoundment structure to impound mine tailings slurry after the certificate terminates unless a new certificate is issued for the dam, reservoir or mine tailings impoundment structure. Those inflows that cannot be diverted may still be allowed to enter the structure, but the lowest possible level must be maintained until safety of the structure is assured. A new certificate shall be issued upon a finding by the director that the dam or reservoir is safe to impound water or mine tailings impoundment structure is safe to impound tailings slurry within the limits prescribed in the certificate.
No action shall be brought by the state against the owner for pollution which may occur in the event that the director orders emergency dumping or bypassing.
With respect to written consent for use of a dam which has been issued and which is in effect prior to the effective date of this act or mine tailings impoundment structure which has been issued and which is in effect prior to the effective date of amendment, the director shall issue a new certificate of approval, which shall supersede the previous written consent for use, or shall contain such terms and conditions as the director may prescribe or shall revoke the existing written consent for use if he finds that the dam or reservoir is not safe to impound water or that the mine tailings impoundment structure is not safe to impound mine tailings slurry.
