Identification of Water Systems <br />The proposed operation is located in the floodplain of St. Vrain Creek. <br />St. Vrain Creek flows through the property from west to east. Two irriga- <br />tion canals pass through the southern portion of the permit areas; namely, <br />Last Chance Ditch and Rural Ditch. The land is located above the St. Vrain <br />Creek alluvial aquifer and also is in a recharge area for the aquifer and <br />creek. <br />B. Water Quality Management Plan <br />The sand and gravel deposit in the alluvium contains the alluvial <br />groundwater system. There is considerable interaction between the ground- <br />water system and St. Vrain Creek. The previously excavated area contains <br />approximately ten feet of water during spring and early summer months. The <br />water level is expected to be lower during late summer and fall months. <br />Mining will begin and has already occurred adjacent to St. Vrain Creek. <br />These mined-out areas which will fill and already be filled with groundwater, <br />will collect any surface water runoff which may flow across the disturbed <br /> <br /> <br /> <br />area towards the creek. <br />If de-watering operations are necessary only clarified water will be <br />discharged from the pits. There will be sufficient time to settle out any <br />solids prior to discharge. <br />Once mining ceases and the area is reclaimed to a wildlife habitat, <br />1 <br />the ponds themselves may be classified as "state waters" <br /> <br />
