• iii iiiiiiiiiiiiiiii ~ <br />MEMORANDUM <br />TO: Humphries, Oehler, Pendleton, Stevens <br />FROM: POSey <br />RE: Review of Battle Mountain's Protocol Document <br />Attached is my review of the Battle Mountain Protocol Proposal for sampling and <br />analysis of surface, ground, and process water solutions and lysitneters. Also <br />attached is a copy of Dr. Hyatt's review. <br />Please recall that this is due May 20. <br />I'll be in the field May 18-22, so cannot respond to your comments. If they are <br />significant, or if my review needs a lot of work, I suggest that someone <br />(Gilstrap, etc.) merge my comments with your own. [Details: My document is <br />formatted in WordPerfect. When you squeeze WordPerfect through the Wang tubes <br />into an Officewriter document, the formatting gets stuck on the tubes. So, <br />please have someone walk back through it and be certain that CN- gets changed <br />back to CN~, C02 gets changed back to COZ, and underlined things stay underlined. <br />Thank you.] <br />Dr. Hyatt made several suggestions about having the Conservancy Commission review <br />the incoming data from Battle Mountain. It is my assumption that Battle <br />Mountain, not MLRD, is supposed to be supplying the Conservanc with data. <br />Likewise, I don't think the Board meant for the Conservancy to b~ involved in <br />this process forever, and Dr. Hyatt's group clearly intend to stay involved for <br />the long run. we should consider making that clear to them, if not also to <br />ourselves. Otherwise, his comments are generally excellent aid definitely <br />deserve consideration. (Please note my disagreements with his note number 2.) <br />we are still waiting on the Pond Characterization Study, and the Results of it <br />will affect the sampling protocol. I'll review that when I return. Despite Art <br />Lefler's over-the-phone comments to the contrary, I believe the data he mentioned <br />reflect real vertical variations in the ponds, that higher cyanide levels occur <br />in the deeper samples, and that composite samples will need to lqe collected. <br />However, we will need to study the data when they arrive, and discuss them with <br />the lab. <br />m:min/staff.mem <br />r~CYO~//t <br />l~'~c- ~- <br />s/~ 7 <br /> <br /> <br />~(4'J•LC/J <br />_~z~. , <br /> <br />
