SON[~RSET <br />M/ N/ N G C O M P A N Y <br />Certified Mail <br />Return Receipt Requested <br />May 6, 1994 <br />Joe Gallob <br />P.O. Box 520 <br />Somerset, CO 81434 <br />Re: Public Notice <br />Dear Mr. Gallob: <br />iii iiiiiiiiniuiii <br />R~C~~~FD <br />MAY 121994 <br />Divsioq or im~norC s a UeG o9y <br />The cabin you currently inhabit in the southeast quarter of <br />Section 10 is located near Somerset's mine workings. The First <br />North Mains are located approximately 480 feet north and about 350 <br />feet below the cabin. During April and May, 1993, the First North <br />Mains were developed north of the cabin. <br />Somerset's Division of Minerals and Geology ("DMG") permit uses a <br />25 angle of draw to calculate the lateral extent of subsidence. <br />By applying the 25 angle of draw to the 35D feet of overburden, it <br />can be determined that the surface could be affected 163 feet south <br />of the First North Mains in the vicinity of the cabin. If <br />subsidence did occur as projected, a buffer of 317 feet (480 - 163) <br />would exist between the maximum projected lateral extent of <br />subsidence and the cabin. Somerset does not intend to take any <br />measures to prevent susidence in the First North Mains in the <br />vicinity of the cabin. <br />The DMG does have rules that require certain notice be given to <br />owners of property and residents within the area above the <br />underground workings and adjacent areas. Somerset does not believe <br />regulatory notice is necessary because the cabin is outside of the <br />area of projected subsidence. However, this notice is given in <br />case some overzealous regulator decides at some future date that <br />notice was required. <br />Please call if you have any questions. <br />Sincerely, <br />~ ~•~ <br />L- <br />Walter L.
