<br />the excavation during heavy storms. Historically, major sur- <br />face drainage left the area as sheet flow to local gullies <br />and swales. It will now be directed to these discharge points. <br />This is not expected to have any significant impact on the <br />flow characteristics of the creek. The cuts through the berm <br />will be reseeded and protected by channel armoring. In ad- <br />dition, some erosion control measures such as staking straw <br />bales across the channel invert to contain sediment from minor <br />storm events will be done. <br />Dust control and wash water for use as part of the opera- <br />tion will be stored in the ponds as noted on exhibit C. Water <br />use and storage rights will be applied for and augmented as <br />detailed in the attached research letter shown as exhibit P. <br />As previously noted, the undersize fraction of the material <br />is left in the pit. It is expected that the reclaimed area <br />to the east of the operating cut will be approximately 4 feet <br />lower than the virgin ground to the west. It is unlikely that <br />this material will ever be of economic use, as the available <br />resources in the Denver metro area will last well beyond the <br />proposed mine. <br />Access to the pit will be via Weld County Road 124. The <br />plant will normally employ 8 people, resulting in 16 light <br />vehicle trips per day. In the event of a highway project on <br />I-25 or U.S. 85, approximately 80 truck-trips per day can be <br />expected. Westbound traffic will travel west on 124 for two <br />miles, north on road 17 one mile and jog to I-25 on road 126 <br />west. Eastbound traffic will proceed north on road 21 and <br />east to U.S. 85 on road 126. Blading and dust-control mea- <br />- 3 - <br />
