Dept. o! Natural Resourcr.G <br />In regards to the subject of a french drain installation at the <br />Blue Ribbon Mine in Delta County, Colorado. <br />Attached is the french drain design prepared by Ute Engineering <br />that was discussed in our March 15, 1982 meeting. From preliminary water <br />level readings taken from piezometers installed along the outer edge <br />of the Blue Ribbon bench I feel a french drain will not correct the slide <br />problems at the Blue Ribbon mine. <br />I suggest a site meeting with you and Mr. Pendleton of your office <br />to discuss other solutions to the problem. <br />Sincerely yours, <br />/~~-~~ <br />Marvin E.
