I also observed the minor <br />subsidence in the mine reclaimed area. It appeared that no additional subsidence had <br />occurred and that the area was safely isolated with stakes and orange netting. I will <br />continue to inspect this area durine the nond inspections. G;_ n <br />Sincerely yours, <br />~~~~ <br />Greg Lewicki, P.E. <br />Greg Lewicki and Associates <br /> <br />
