was back in 2008. <br />Field 3 size was determined by using the excess Lift B topsoil from stockpiles <br />and future stripping that would be left over after placement of Lift B in Field 4. <br />• Again, Lift B topsoil will average 33 inches in Field 3. DRTMS directed WFC to <br />then take all of the A/B Mixed stockpile and evenly spread it over Field 3, 2 and <br />1. That A/B thickness is calculated to be approximately 21 inches. In <br />conclusion, Field 3 will receive 33" of Lift B topsoil plus 21" of A/B Mixed <br />topsoil for a combined 54 ". <br />Field 2 is 7.84 acres. OB1 topsoil substitute material that has to meet all of Lifl <br />B topsoil chemical and physical values will have to be use for Lift B topsoil. <br />Thickness will be greater than 33 ". WFC actually tested OBI substitute to 48" <br />and we know it is thicker than that. A/B Mixed topsoil will then be placed over <br />the: OB 1 substitute Lift B topsoil and it will average 21 inches. So combined, <br />there will be 54" plus of topsoil and topsoil substitute. <br />Field 1 is 12.21 acres. The underlying foot print of this area consists of OB I <br />substitute Lift B soils. Again, the thickness of this zone will be 33" plus. Again, <br />A/B Mixed topsoil will have to be used for the top Lift of topsoil. As mentioned <br />above, an average of 21 inches will be placed for Lift A. As mentioned above, <br />• there has been some pushing and some rough spreading of Litt A/B mixed topsoil <br />in :Field 1. Past measurements says the upper topsoil lift is presently 17 inches <br />thick. WfC will go back in and put more Lift A/B Mixed topsoil to raise the <br />already existing 17inches to a total of 22" of Lift A/B topsoil. <br />In conclusion, there will be 7.58ac + 12.21 ac =20.01 acres of suitable OB 1 <br />substitute topsoil and A/B Mixed topsoil IC land. Field 1 -5 adds up to 107.96 <br />acres. <br />WPC will have to stockpile a sizeable (132,222cy) amount of OB I material for <br />the tonal pit cut(s). This can be seen on the attachment. Also, three different <br />stockpiles will need to be made over in the area of Pond 011. One will contain <br />OB 1 fill for the bottom of Pond 011 and two other piles of Lift A and Lift B <br />topsoil to cap over 011 Pond. <br />• <br />
