<br />installed a floor sump directly in front of the barrier. This sump is <br />connected to a larger sump on the lowest floor of the mill. The <br />only liquid that will be stored or used on this upper working level is <br />fresh water. <br />Barrier #2 is located on the lowest level of the mill, in front of the <br />exit door on the East wall of the plant. It is between the thickener <br />tank and the flotation circuit. <br />We installed a large floor sump on this level. The sump has a <br />pump, and pump any spillage to the thickener tank or alternatively <br />to the tailings pond. <br />We also installed two secondary containment walls on this level. <br />One is on the East wall of the access tunnel going under the <br />thickener tank. You have previously inspected and approved this <br />uvall. <br />The second containment wall is on the North wall, East end, <br />securing the concentrate storage area. Additionally, the ground <br />level outside of this area has been raised approximately 6 feet in <br />elevation, serving as a tertiary barrier. <br />We believe that these changes in plant design will provide a much <br />better control and containment system for any spillage of solutions <br />or slurries in the mill. <br />Please let us know if vre can take down the lwo barriers <br />referenced above. We expect MSHA to inspect the mill in the next <br />one to two weeks. <br />Sincerely, <br />~17.t~Gvt.2, <br />Mallb.. ne Stewart <br />
