All three are fence <br />corners that have pulled out of the ground at some time in the past fifteen or more years. All three were <br />constructed of steel angle set in concrete about 2.5 ft. in the ground with steel angle braces also set in <br />concrete. One is at the NW corner of Section 31, T20S R69W; another is at the E1/4 corner of Section 24, T20S <br />R70W, and the last is at a fence corner in the NE1 /4 Section 24, T20S R70W with the Southfield coordinates of <br />13400 ft. N and 9320 ft. E. All three are above pillared areas of the Southfield Mine. As with our water well <br />and cement block barn. we do not have pre- mining elevations of these fence corners. However, this fence <br />damage happened after the mining, and our observations of our fences show that in areas of known subsidence <br />additional tensioning of the barbed wire occurs when a section of the fence subsides even just a few feet. <br />The main purpose of writing about the fence damage is in response to the Minor Revision 59 application. If the <br />last subsidence survey is done in the penultimate year of the permit period, <br />there will only be one measurement of the locations and elevations of our water well and barn, assuming that <br />Energy will be directed to include these significant structures in the subsidence monitoring plan. An immediate <br />survey now and then again in the penultimate year would yield the only chance to monitor these two structures <br />with a minimum of two surveys since all prior opportunities to monitor them has been lost forever. Also, it is <br />unknown at least to me when the final year might be. <br />WD Corley, Jr. <br />
