6.4.4 Exhibit D <br /> Mining Plan <br /> Location and General Land Use Information <br /> The site is located along Alamosa County Road 112 S and is composed of rangeland. The parcel <br /> is owned by Southwest Ready-Mix, Inc. <br /> Site Geology and Vegetation <br /> Site geology consists of 6 inches of topsoil. Mining will occur to a depth of approximately 10 <br /> feet.There are no hazardous or acid forming materials expected to be encountered during <br /> excavation. See the enclosed Natural Resources Conservation Service(NRCS) soil report for <br /> more details on surface composition. A majority of the site is composed of Alamosa <br /> Loam/Alamosa Loam, saline. This material is poorly drained with very high runoff. These soils <br /> are used for farmland if irrigated and reclaimed of excess salts/sodiums. Native vegetation is <br /> alkali sacaton, blue grama, saltgrass, western wheatgrass, rabbitbush and greasewood. <br /> Vegetation at this site covers approximately 30-60% of the site. <br /> Surface Hydrology <br /> Current topography is shown on the Existing Conditions Map. All runoff on the undisturbed site <br /> runs to the southeast. Stormwater will be kept from leaving the site by using the topography. The <br /> site is depressed and holds water currently. Based upon onsite conditions, groundwater is found at <br /> approximately 3 feet. <br /> Wildlife <br /> Environmental conditions, such as food and cover availability, is limited due to the climate. <br /> Small animals (rabbits,coyotes,etc.) are found in the surrounding environment. The site may <br /> also see white tail deer, antelope, prairie dog, various snakes and lizards. Impacts to wildlife <br /> will be mitigated through a weed management plan and reseeding all mined areas with a native <br /> rangeland seed mix. <br />
