ameO <br />Earth & Environmental <br />smooth drum vibratory roller. Fill placement by method specification as outlined in the Project <br />Documents. <br />2) LOB Conveyor Corridor <br />Rockbreakers completed drilling blasting pattern at cut area at conveyor transfer station 5. Cut <br />area has not been shot yet. <br />C) Subgrade Preparation <br />1) LOB Pad Soil Liner Fill (SLF) <br />The SLF and fine grading of the LOB Pad was completed on Wednesday AM in preparation <br />for the Geomembrane. Field densities taken by Nuclear Methods (ASTM D-2922 & 3017) are <br />passing with tests > 95% of Standard Proctor (ASTM D-698). Water contents were at or near <br />optimum. Depth checks to verify clay thickness were taken and recorded on the SLF. Depths <br />measured meet or exceed the project specifications. All depth check holes were filled with a <br />mixture of bentonite and water. <br />2) LOB Conveyor Corridor <br />Conveyor Alignment 1, Station 0+00: Repairs to the Geomembrane have been completed, <br />tested and recorded on Phase IV pad. 2-feet of drain cover fill was placed on the <br />Geomembrane completing the work. 2-feet of select structural fill placed and compacted to the <br />bottom elevation of the planned footing. In place densities by Nuclear Methods (ASTM D- <br />2922 & 3017) indicated tests were passing with results of 97% and 98% of D-698 (Standard <br />Proctor Density). The moisture contents were near optimum. <br />With the remediation work completed for underground working 2039, located within conveyor <br />corridor 1, method specification structural fill resumed. <br />D) SLF Processing (Material is being generated/processed for the LOB and the VLF) <br />SGOSA (Squaw Gulch Overburden Storage Area) Dump 5: <br />Summary of SLF processing for the week. <br />Location This Week Cumulative Comments <br /> (tons) (tons) <br />SGOSA Dump 5 Clay 572 <br />7 35,068 Total includes through Apr. <br />` <br />Processing , 20, <br />09 <br />Totals 7,572 35,068 <br />E) South Cresson Clay Stockpile <br />The mine was transporting clay to the South Cresson stockpile intermittently throughout the week. <br />F) AGOSA (Arequa Gulch Overburden Storage Area) Material Processing <br />Processing materials for the VLF and LOB continued throughout the week.
