This work is needed to ensure that the conveyor remains stable, as the <br />hillside continues to move. <br />The work will be done at the concrete piers, which support the conveyor located above the main <br />mine access road. Four holes, 24 inches in diameter will be augered on the upslope (or south <br />side) of each of the piers. The holes will be approximately 30 feet deep or to bedrock, whichever <br />comes first. The holes will be filled with two pound, 13 psi polyurethane foam. <br />The foam is intended to absorb the pressure put on the conveyor supports from the moving <br />hillside. When the pressure collapses the foam, new holes will be drilled and they will be filled <br />with foam. Given the rate of movement that MCC has observed in the past, this work will <br />probably be completed every two years and would consider the work to be maintenance. The <br />work is scheduled for the last week in August and should be completed by the end of the week. <br />Please call if you have any questions. <br />cc: Norm Every <br />Kathy Welt <br />081996.doc <br />
