<br />• <br />July 1993 <br />-15- <br />923-2515 <br />Reclamation Division (CMLRD) on June 30, 1991. Section 2.068, "Surface Coal Mining and <br />Reclamation Operations on Areas, or Adjacent to Areas, Including Alluvial Valley Floors", on <br />page 142-144 is as follows: <br />(i) The Division shall determine that an alluvial valley floor exists if it finds that: <br />(A) Unconsolidated streamlaid deposits holding streams of sufficient size and <br />inherent productive potential to support agricultural activities are present. <br />If not currently being farmed, the minimum size of the alluvial body shall <br />be based upon the accepted regional practice. <br />(B) There is sufficient water to support agricultural activities as evidenced by: <br />(I) The existence of flood irrigation in the azea in question or its <br />historical use; <br />(II) The capability of an area to be flood irrigated, based on <br />streamflow water yield, soils, water quality, topography and <br />regional practices; or <br />(III) Subirrigation of the lands in question, derived from the ground <br />water system of the valley floor. <br />(ri) The Division shall determine that an alluvial valley floor does not exist if it finds <br />that: <br />(A) No streamlaid deposits meeting the pertinent size criteria as set forth <br />under 2.06.8(3) (c)(i)(A) aze present as determined from geologic maps, <br />results of field investigations or similar studies; <br />(B) There is insufficient water available to support flood irrigation or <br />subirrigation agricultural activities based on established regional practices <br />determined from hydrologic characteristics; and analysis of the potential <br />of the azea for successful irrigation based upon its soils, climate, <br />vegetation, and land use; or <br />(C) The azea is generally overlain by a thin veneer of colluvial deposits <br />composed chiefly of debris from sheet erosion, deposits by unconcentrated <br />runoff or slope wash, together with talus, other mass movement <br />accumulation and wind blown deposits. <br />• <br />Golder Associates <br />
