All incidences that have the potential to adversely affect <br />groundwater, including but not limited to spills, shall be <br />verbally reported to the City within 24 hours.

Mining activities <br />shall not take place closer to ground water levels than <br />indicated in the plans submitted without amending this <br />conditional use permit; however, if mining is proposed to <br />occur below the water table in the future, the above <br />referenced wells shall be monitored for DRO prior to <br />excavation activities commencing and after their <br />cessation each year. Further, in the event of a spill, <br />appropriate water tests (as determined by the city) will be <br />taken until the spill is deemed clean by the city. <br /> <br />g.

Thereafter, the aforementioned well shall be <br />tested a minimum of twice per month, said frequency to <br />be increased during dry periods. A drop in water level of <br />twelve (12) inches or more shall be immediately reported <br />to the city. <br /> <br />s:\planning\case files\2005\cu 05-21 bauerly\gravcup-amend bauerly.doc <br />
