Section 785.19 (d) Continued. • (iv) Surveys and data required under this paragraph for areas designated as alluvial valley floors because of their subirrigation characteris- tics, shall also include, at a minimum, geohydrologic data including observation well establishment for purposes of water level measurements, ground water contour maps, testing to determine aquifer characteristics that affect waters supplying the alluvial valley floors, well and spring inventories, and water quality analyses describing seasonal variations over at least one full year, and physical and chemical analysis of over- burden to determine the effect of the proposed mining and reclamation operations on water quality and quantity; (v) Plans showing how the operation will avoid, during mining and reclamation, interruption, discontinuance or preclusion of farming on the alluvial valley floors unless the premining land use has been unde- veloped rangeland which is not significant to farming and will not materially damage the quantity or quality of water in surface and ground • water systems that supply alluvial valley floors; (vi) Maps showing farms that could be affected by the mining and, if any farm includes an alluvial valley floor, statements of the type and quantity of agricultural activity performed on the alluvial valley floor and its relationship to the farm's total agricultural activity including an economic analysis. (vii) Such other data as the regulatory authority may require. (3) The surveys required by this paragraph should identify those geo- logic, hydrologic, and biologic characteristics of the alluvial valley floor necessary to support the essential hydrologic functions of an alluvial valley floor. Characteristics which support the essential hydrologic functions and which must be evaluated in a complete applica- tion include, but are not limited to: 785-30
