<br />. <br /> <br />Groundwater monitoring wells shall be installed <br />in locations and depths as recommended by the <br />City's consultant. Water level monitoring and <br />water quality monitoring shall be conducted <br />pursuant to the consultant's recommendations. A <br />description of the monitoring system shall be <br />submitted to the City for approval fourteen (14) <br />days prior to construction. The monitoring <br />system shall be complete prior to commencing <br />mining activities. <br /> <br />h.
