The main sources of potential sediment on site are fines from the cutting of marble blocks from <br />underground. The fines mixed in with water during the cutting process, and pumped out of the mine as <br />slurry. Historically this slurry has been placed on designated pile sites to dry out. This area is the Mud <br />Drying Dump on Map C-2. Other dumps can also be seen on Map C-2, and contain some combination of <br />marble fines or marble blocks. The sediment sumps proposed in this plan will trap and contain all of the <br />water from a 10-year event on site. Each sump will provide sufficient detention time to ensure that <br />sediment drops out of the contained water within 48 hours due to the granular nature of the material at <br />the bottom of the sumps. CSQ's experience on site has been that most water contained within a sump <br />infiltrates into the underlying soil and rock. However, each sediment sump is designed with a water <br />discharge emergency spillway to allow for water to leave the sump once sediment has dropped out or to <br />allow discharge of waters greater than the 10 year event. Although no discharges are expected for any <br />event up to 10 year frequency, any discharges will be regulated under a Colorado Department of Public <br />Health and Environment (CDPHE) discharge permit. <br />Yule Quarry April 10 18
