The numbers in the pre-mining elevation <br />for monitoring point J18 were inadvertently transposed. The report states the elevation <br />to be 6921.0; the correct elevation is 6912.0. With the correct elevation, the subsidence <br />for the reporting period is 2.9 feet, and the total subsidence is also 2.9 feet. The correct <br />maximum subsidence for the J-line is 9.4 feet. <br />Please note this transposition error also exists in the July-December 1994 subsidence <br />report. <br />Should you have any questions, please contact me at (970) 824-1418. Thank you for <br />your assistance with this matter. <br />Sincerely, <br />Ippa,.,o~ S~+- <br />Alana L. Scott <br />Environmental Engineer <br />P.0.
