111NING PLAN I?YHIBI'1' U <br />1. Cencr:(I dining t'lan <br />The property buundaq has be~ht survcytxl on site and the permit area will be surveyed prior to <br />any site disturbance. \1ap C-3 shows the training plan. <br />The gravel zone is approximately ZG feet thick in an alluvial deposit and is overlain by soil and <br />overburden ranging from 6 inches to 20 legit. The deposit will be mined in a fi~ur pit sequence, <br />beginning with the southwestern-most pit. The southwest and southeast pits (Pits I S~), along <br />with the southern ph;ues of the hvu large northern pits (('its ? & ~lj, arc un the lower terrace <br />while the northern halves of Pits 3 &t 4 arc on a terrace approximately ZO feet higher. Overburden <br />and utpsuil will be rcnuwed via either hulldorcr or scraper in all pits, establishing a 2H:1 V slope <br />in wch pit. Initially, in Pit 1 (sett Map G?)overburden and topsoil is stockpiled to the immediate <br />northwest of t}te pit. l;lwn completion of the mining of Pit 1, the overburden stockpile will be <br />used to build both the ?H:I V reclaimed slope and the wetland shelves as shown in Map F-I. The <br />overburden and topsoil removed liom Phase I of Pit 2 will be placed in Pit 1 to complete the <br />wetland shelves.
