Page 4 <br />18 December 1979 <br />Exhibit F. <br />1. Zone I represents an area where slopes are in the vicinity <br />of 3 to i as is the immediate surrounding topography. The planned <br />Drainage of runoff into Maverick Gulch from the quarry site will be <br />controlled by surface manipulation utilizing furrow-contouring at <br />right angles to the lay of the slopes to impede runoff and retain <br />soil moisture. The quarry site is situated at a downslope position <br />below a precipitation absorbtion area of approximately 50 Acres. <br />The broken-rumpled-rocky condition of this upslope area portrays <br />no physical evidence of erosive surface runoff on to the mine site. <br />2. These slopes will be cut back and contoured. <br />Exhibit G. <br />1. Water uses are addressed on page 2 of this letter (Exhibit <br />G-1). <br />2. Runoff waters at the quarry will be contained by providing <br />water-break contour-furrows across the lay of the slopes on all <br />steep affected-Tand surfaces. <br />• Runoff waters in the vicinity of the fertilizer plant and <br />crusher area are immediatlly absorbed into the surrounding low- <br />sloped alluvial land(4a slope). <br />Exhibit J. <br />To offset the low survival problem of seedling trees, we <br />1 will <br />1. Plant in the spring (March 15th). <br />2. Provide depressional area for water accumulation around <br />seedling. <br />` 3. Place cedar shingle for shade on the south side of seedling. <br />/{! 4. Double the amount of seedling trees per acre from 20/acre <br />recommended by Dr. Owen to 40/Acre. <br />Yours very truly <br />~~Y <br />Robert G. Biglow <br /> <br />
