Ground-water monitoring shall be conducted according to the ground-water monitoring plan approved under §2719 The office may require additional monitoring when necessary.2. Ground-water monitoring data shall be submitted every three months to the office or more frequently as prescribed by the office.

Equipment, structures and other devices used in conjunction with monitoring the quality and quantity of ground water onsite and offsite shall be properly installed, maintained and operated and shall be removed by the operator when no longer needed.B.

Surface-water monitoring data shall be submitted every three months to the office or more frequently as prescribed by the office. Monitoring reports shall include analytical results from each sample taken during the reporting period.

Surface-water monitoring shall proceed through mining and continue during reclamation until bond release. The office may modify the monitoring requirements, except those required by the NPDES permitting authority, including the parameters covered and sampling frequency if the operator demonstrates, using the monitoring data obtained under this Paragraph, that:a. the operator has minimized disturbance to the hydrologic balance in the permit and adjacent areas and prevented material damage to the hydrologic balance outside the permit area; water quantity and quality are suitable to support approved post-mining land uses; and the water rights of other users have been protected or replaced; orb. monitoring is no longer necessary to achieve the purposes set forth in the monitoring plan approved under §27194. Equipment, structures and other devices used in conjunction with monitoring the quality and quantity of surface water onsite and offsite shall be properly installed, maintained and operated and shall be removed by the operator when no longer needed.La.
