Herron; Z) 06/24/83 with <br />J. Herron, S. Emrich, and B. Munson; and 3) 07/08/83 with J. Herron and S. Emrich. <br />The results of previous studies were reviewed to determine the extent of work that <br />would be required. <br />Soils <br />3'~previous soil study was determined to be adequate since it covered sufficient <br />detail for both the surface facilities and the waste disposal azeas. The only <br />additional work required is to supplement the samples that were collected by <br />horizon with a set of samples from each series by six-inch depth intervals. These <br />samples would be analyzed for the same pazameters as the others. <br />Vie e~a~tion <br />A tee r ievlewing all existing data and development plans, a satisfactory vegetation <br />study program was developed. Additional cover, production, and shrub density data <br />would be required. Because the predominant vegetation type in both the surface <br />facilities and waste disposal azeas is sagebrush, it was decided to use the same <br />reclamation standazd for both azeas. Because the surface facilities azea had been <br />previously disturbed by mining and overgrazing, a three (3) acre fenced reference <br />azea to be used to determine the reclamation standazd will be located neaz the <br />waste disposal azea. Cover and production will be adequately sampled both on the <br />waste disposal azea and within the reference azea, and shrub density will also be <br />recorded. A minimum of five lines will be run within the surface facilities azea to <br />show that it is similaz to the other azeas. <br />
