DEPT. OF NATURAL RESOURCES <br />Gravel has been mined in an dry alluvial open pit to an .approximate elevation <br />of Q270, as shown on Exhibit C in the existing mining area. Ihrring the present <br />stage of operation, gravel will be removed from the area north of the existing <br />floor by dozing down slope on the north wa7.1 in west, east and south directions <br />toward the c~ueher. It is planned to crush all of the gravel obtained in this <br />manner on Hite. The pit, floor vill ba expanded and the crusher ralornted to th~~ <br />north as the wall is mines! away. The process will continue until the west and <br />north slopes have been mitred to the extent shown in Exhibit F. "Pit. Run" <br />gravel will be taken ocasaionally from the oast wall with front end loaders. It <br />is anticipated that this will represent l.esa than 10;6 of all gravel. mined. There <br />ie no overburden and uirtllally no topsoil to he stripped anti spoiled or stockpiled. <br />The gravel stratum is exposed thruout. the site. 3~rrfacF, rwroff, resulting from <br />heavy rains. is kept away from the crusher and adj+rcenc floor ~y boing channe]ed <br />to the southwest corner to a reacessed area that can be seen in Exhibit C. Here <br />it infiltrates into the underling sands and groundwater. <br />The present stage of operation involves only the west approrimate 10 acres. <br />An estimated additional 3(10,000 tons can be taken from this 10 acres, supplinE; <br />tha eoranty for tho next 7-•10 years. Approximately 300,000 tens has been mined <br />to date. Thruout the operation, 3-4 acres would be classified as a major dis- <br />tilrhance aroa involved wil;h the earthmoving of gravel towards the crusher. <br />Another 3-4 acres would ba classified as moderate disturbance consisting primarily <br />i <br />of the adjacent pit floor„ The remainder are minor disturbance areas, The west <br />TO acres will be reclaimed after completion of mining operations there. <br />
