6. General Effects of the Operation on the Existing Wildlife of the Area <br />Gravel extraction and crushing activities will no doubt create some disturbance to animals near <br />the site. The portion of the site which lies on the north side of the river has been active for <br />nearly 25 yeazs. The change in impact from the current operation to the plans set forth in this <br />amendment can basically be described as a lessening of habitat for big game and small <br />mammals due to reduction in riparian and pasture areas and an increase in waterfowl habitat <br />due to the increase in wetlands and water areas. The portion of the site which lies to the south <br />of the river has not been mined previously, however the site is surrounded by I-70, Lafarge's <br />Mamm Creek Pit, and the Colorado River. It should also be noted that along the entire stretch <br />of river bordered by the Scott Expansion mining has occurred along the northern shore. <br />Migrating animals will probably avoid the site, but the proposed pit does not block any known <br />migratory routes, and wildlife should be able to move through the area unimpeded. Due to the <br />possibility for animal/vehicle collisions, hauling activities will probably pose the biggest threat <br />to wildlife. Haul trucks should keep to posted speeds and drivers need to remain aware of the <br />potential for collisions. <br />4/26/04 Page H-3 <br />
