1.2 Description of Construction Activities <br />Construction activities will include the construction of the main access road, plant <br />facilities, well field pipeline and access road, well pads, well field drainage pond (or <br />tank), and monitoring wells with access roads. A staging area with a temporary concrete <br />batch plant will also be included in the construction activities. See Revised Figure C -1. <br />1.3 Soil Disturbing Activities <br />Following is a tentative list of soil disturbing activities: <br />Installation of erosion and sedimentation control measures, <br />Clearing, grubbing, and grading for the above mentioned facilities, <br />Construction of the above mentioned facilities, <br />Installation of final erosion and sedimentation control structures. <br />1.4 Intended Sequence of Major Construction Activities <br />1.5 Project Area <br />2 <br />The final order of construction activities is somewhat uncertain due to variables that are <br />often encountered during construction. The following description of construction <br />sequence can be found also in Section E -2 of the Reclamation Plan in the Division of <br />Minerals and Geology (DMG) 112 Permit Application enclosed with this SWMP as <br />Attachment 1. <br />Specific activities will be preferentially performed during initial land disturbance. Where <br />needed on slopes and/or on erosive soils, perimeter erosion and sediment controls will be <br />constructed before other surface disturbance activities. Next, roads will be constructed <br />with appropriate erosion and sediment controls incorporated during construction. <br />Simultaneously with road construction and as needed for construction of erosion control <br />and sediment control structures, soil will be salvaged. After these measures have been <br />implemented, the components associated with the well field and processing facilities will <br />be constructed. <br />Placement of erosion and sediment control structures will parallel the development of the <br />well field and process facilities. Topsoil stockpiles and accessible cut and fill slopes of <br />ponds, roadways, and other facilities will be seeded at the first available planting time <br />(i.e., fall or spring) after construction. These components will be re- vegetated to enhance <br />viability of stockpiled topsoil and to minimize potential erosion problems with both <br />stockpiles and facility cut and fill slopes. The seed mix shown in Table E -1 in <br />Attachment 1 will be used. <br />Table 1 presents a breakdown of the estimated areal extent of disturbed areas within the <br />Project Area by various descriptors. <br />
