• -31- MR. R. COHEN: Most of the core samples revealed that there was very little acid potential. There are some occasional ones, I think, with a slight acid potential. Overall, the other cores from this report here suggested that there was a low level or no level acid generating potential and, therefore, a low level metals potental. MR. JOUFLAS: Thank you. Any further questions? Okay. Thank you very much, sir. MR. R. COHEN: You're welcome. MR. NEIL COHEN: The next witness is Joe Gallegos and he was sworn in, in Alamosa. MR. GALLEGOS: Ni, J1m. I'm beginning to get to know you gays pretty well. I would just like to talk a little bit about the buttress wall. I have • a little - I can only look at things as a layman's view. I am nrot an expert at this, but when it comes to having standing water in a pit, I think it's a - could be a very detrimental thing to our environment there, plus the revegetation I don't think would grow in the water. So, I just have a problem with the magnitude influx from the Rito Se co. It's going to take 200 gallons per minute to have this operation operate. The Rito Seco is going to influx 125 gallons a minute. That's quite a bit of water that is going into that pit. My deal is, besides messing around with grout curtains, the slurry -- well it was a grout curtain now it's a slurry wall. I felt a little bit better wish the grout curtain for same reason. To have this influx occurring could be very detrimental in that to void questions of integrity„ longevity, and so forth to the buttress wall and the slurry wall, it would ;(ust seem like - logically to me to just go ahead and back fill that thing to thEr height of the Rito Seco. Why avoid future monitoring; are we going to havee this thing monitoring for the integrity or are we going to have leaks around it? I think that you would solve a lot of your problems if you could just get that situated, and badcfill and have no problems. That's the way I would look at
