Dave is that ok with <br />you? <br />Thanks, <br />Rob <br />David, Rob, John, and George. <br />I note the Jan. 29, 2014, mid -term response from George Patterson with regard to The Corley Co. water well. I would like to <br />comment about some of George's statements. With regard to the cause of the decreased production of the well, it was not <br />possible in 1992 when George states that Al Weaver and our representative tested the well to be dry to determine the <br />cause, but EFCI was illegally pumping water fromthe nearby north well (now MWNW) without a permit until 1994. Since <br />our well was mapped on the Southfield Mine Map incorrectly until 2013, I believe that the assurances that EFCI's <br />hydrology consultant gave us in 1992 were based on the incorrect well location. They assured us that Southfield mining <br />could not have possibly affected our well, and I relied on their expert opinion at the time. As for possible subsidence, our <br />well pit is a large above ground concrete structure that should have been monitored for subsidence. It is not possible now <br />to document subsidence. However, I believe that George is incorrect that the well is over a barrier pillar. All of the <br />Southfield Mine Maps including the small area map supplied by George with the above stated mid -term response clearly <br />shows our well location to be directly above the portion of removed pillar in the mined panel. It is definitely not over a <br />solid barrier pillar. Both monitoring point I and our well are directly above formerly solid pillars that were removed on the <br />retreat mining. Further, Mine Plan Map 17 shows the barrier pillar to be entirely within the projected angle of draw. As for <br />the release in 1994, our well had been ruined by that date, and we signed the release in order for EFCI to try to obtain a well <br />permit. Had we refused to sign the release in 1994 we would have only hurt the Southfield mining activities and would <br />have not helped restore our well. <br />With regard to Al Weaver's subsidence monitoring report, I did not see any mention of the surface subsidence crack <br />features over the 1 East panel that were repaired in about 2011. There are other surface cracks that I have mentioned that <br />we have found without reporting their location because of the poor repair of the Moose Panel cracks. That repair did more <br />damage to the area than good; please note that I suggested hand shovels instead of a dozer because of the very steep side <br />slope. At least Al's report gives us some credit for assisting with this crack repair. <br />The Illustration I Corley Co. Well Location Map has another error of the location of a fence corner that has been pulled <br />out from subsidence. This map shows a fence corner at approximately 14000 ft. N and 10000 ft. E. The map says that this <br />location is according to Corley. No, the corner on the ground is at the East quarter corner of Section 24, T20S R70W at <br />approximately 12650 ft. N and 9950 ft. E. <br />After reading the EFCI mid -term response perhaps we should rethink our offer we made yesterday to compromise our <br />https: / /mai l.g oog le.conVmai 1 /u /0 / ?ui =2 &i Ire29129fcb5 &view= pt &search =i nbox&th= 14409b6dl3c387a8 1/2 <br />
