Egviroq-qeqt, Iqc. <br />LARRY E. O'BRIAN <br />FOUNDER <br />April 12, 2007 <br />Division of Reclamation, Mining & Safety <br />Mr. Allen C. Sorenson <br />Minerals Section - North <br />1313 Sherman Street, Room 215 <br />Denver, Colorado 80203 <br />Re; Thompson Properties <br />Thompson Resource MLR Permit # - M-1983-102 <br />Technical Revision Adequacy Response <br />Dear Allen: <br />7985 VANCE DRIVE, SUITE 205A <br />ARVADA, COLORADO 80003 <br />303-423-7297 <br />FAX 303-423.7599 <br />On behalf of my client Thompson Properties I am responding <br />to the adequacy items in your April 6, 2007 letter. I will <br />respond in the order of your request. <br />1. Attached are copies of the return receipts for the packets I <br />sent to the objectors. I sent one as a courtesy to Mr. & <br />Mr. Mirabito even though they were not at the M.L.R.B. <br />hearing. A copy of my cover not is also attached. <br />2. We felt it would be prudent to collect data from the well <br />through the life of the mine, just in case. So we confirm <br />that each well will be measured quarterly until mining ends. <br />The first five reading will be sent to the Division once we <br />have the data. There after the data will be sent with the <br />annual report. <br />3. We do not believe that 5 quarters will be adequate to estab- <br />lish a usable trend in ground water. If we attempt to set a <br />fir elevation or range we could potentially be putting our <br />selves into an enforcement actions that we have no control <br />over. I believe that if there are any changes to the <br />groundwater table it be an environmental change not caused <br />by the mine and will have affected the adjoining neighbors <br />wells before we would find it in the monitoring wells. This <br />would happen because our mining activities and monitoring <br />wells are down gradient from their wells. Our concerns with <br />establishing firm ground water levels is that Thompsons <br />could be held libel for activities not associated with mine, <br />i.e., installation of household wells above the mine that <br />draw down the water table, reduced irrigation or even <br />draught. <br />
