Jerry Daub: <br />We would monitor both water level and water quality. <br />Paul von Guerard: <br />Will there be a well in the upper aquifer? <br />Roger Day: <br />And that water level is in the form of a piezometer, so you have a record. <br />Roger Day: <br />In my practical thought, we need to monitor potentiometric head at the dissolution to show <br />that there's no impact coming up from below. We've got an air filled annulus in the wells so, <br />that if there's a leak, it's air —not fluids — leaked to the aquifer. We also propose to monitor <br />the B- Groove so that we have two layers of monitoring between the aquifer and the mining <br />cavities. I feel this technically covers reasonable monitoring requirements, but that's what <br />we're here to negotiate. <br />Paul Daggett: <br />I won't argue that point but if you go to a commercial plant and if you don't have that <br />information, even though it may seem redundant to you, public comments come back that <br />question "How do you know you haven't influenced that ?" Especially if you later run into a <br />different water quality at the A- Groove, after you've done the pilot phase, than what they <br />perceived as normal it is wise to have that to fall back on to prove that, no, this was here <br />before we did it. It's for your own protection to have a baseline on all the aquifers prior to <br />doing any type of injection in there. They may say your injection well leaked into the upper <br />aquifer and you just didn't find that leak or didn't record it somewhere. That's something <br />you might want to think about. If you're serious about going to the commercial phase and if <br />you get a program set up now that potentially covers your commercial phase the extra cost of <br />the monitoring program may be more advantageous to you. I think that it could save a lot of <br />time if you go commercial. <br />Jim Komatinsky: <br />One of the concerns that we had with some other projects, but not as critical with this size <br />project, is subsidence fractures basically fracturing the Mahogany Zone. This would inner <br />change waters from the upper aquifers to the lower aquifers. That would be a concern here. <br />Roger Day: <br />Your point is well taken. It's not just leaks that impact the aquifer. It's the change in the <br />aquitard that's impacting the aquifer. <br />Jerry Daub: <br />From what we know to date and predictions by Agapito for the proposed 6 -well field that we <br />have planned now, there is no impact on the Mahogany Zone. <br />Roger Day: <br />Their prediction is favorable as far as not having subsidence, but on top of that, we also have <br />a subsidence monitoring program that documents whether is has or has not occurred. <br />12 <br />
