The permit area is <br />underlain by the Lewis shale, a predominantly dark -gray to bluish, marine shale of Cretaceous <br />age. The Lewis shale dips a few degrees generally northward into the Sand Wash Basin. The <br />shale beds have weathered out to form gently sloping hillsides on either side of the nearly level <br />alluvial valley floors and terraces found along Dry Creek. <br />Surface waters do not appear to be in hydrologic communication with the Twentymile <br />Sandstone, a significant regional aquifer that underlies the Lewis shale. Ground water <br />movement is described below and in Tabs 7, 14, and 15 of the permit application package (PAP) <br />More detailed geologic information, including geologic maps and a generalized geologic cross- <br />section, can be found in Tab 6 of the permit application. <br />Soils <br />Soils in the Dry Creek area range from clays to loams. The soils are of limited agricultural use <br />due to high concentrations of sodium. Information on soils can be found in Tabs 9 and 19 of the <br />PAP. Specific findings related to soils are described in Section B, Item IV of this document. <br />Surface Water <br />Surface water information is found in the following sections of the PAP: Tabs 7, 12, 13, 14, 15, <br />and 16 and Exhibits 12-2, 12-3, and 12-4. A summary of this information is included here in the <br />Description of the Operations Plan and in Section B, Item III of this document. <br />Co <br />
