During the present stage of operation, grave:L will. be removed from the urea north of the. existing floor by dozing down slope on the north wall in west, east and south directions toward the crusher. It is planned to crush all of the gravel obtained in this manner on site. The pit floor will be expanded and the crusher relocated to the north as the wall is mined away. The process will continue until the west and north slopes have heen mined to the extent shown in Exhibit F. "Pit Run" gravel will be taken ocas:aionally from the east wall with front end loaders. ~It is anticipated that this will represent less than 10;6 of all Bravo] mined. There i.e no overburden and virtually no topsoil to he stringed and spoiled or stockpiled. The gavel stratum is exposed thruout the site. Surface runoff, resulting from heavy rains. is kept away from the crusher and adjacent floor by being channeled t~, the southwest corner to a reacessed area that can be seen in Exhibit C. Here it .infiltrates into the underling sands and groundwater. The present stage of operation involves only the west approximate 10 acres. Au estimated additional 3t>o,000 tons can be taken from this 10 acres, suppling tFle county for tho next 7•-10 years. Approximately 300,000 tans has been mined to dada. .Thruout the operation, 3-4 acres would be classified as u major dis- t~irhance aroa involved with the earthmoving of gravel towards the crusher. Another 3-Q acres wotil d be. class ified as moderate disturbance consisting primarily of the adjacent pit floor. Tha remainrisr are minor disturbance areas. 'the west 10 acres will be reclaimed after completion of mining operations there,
