deep which will receive the used process water and the rejected material from the <br />sample plant separation. Periodically this rejected material will be removed and <br />allowed to drain and dry before it is used to backfill the drill holes. <br />3.) The drill holes will be reclaimed. Just what that will mean in each case is hard to <br />determine until the hole has been drilled and whatever damage has occurred in the <br />process is evident. Topsoil saved from the collar of the hole or derived from <br />elsewhere will be used to cover the top of the hole itself. The bore will be <br />backfilled with the cuttings retrieved from the sampling plant collection pit. This <br />backfill will be approximately equally permeable in all axes. I think that because <br />the sandstone in which the holes will be drilled is an unconfined aquifer that it <br />won't do much good to place bentonite in the hole and no bentonite will be used in <br />the drilling of the hole. However, if so deemed, we can place bentonite in the <br />bottom. If you want a concrete plug at the top of the hole but a foot or two below <br />the surface, that can be accomplished and more cuttings and topsoil can be placed <br />on top of it for complete reclamation. I have contacted the BLM Field Office in <br />Craig which sent me the seed mix formula used in the area where we may be <br />drilling but note that they tailor that mix somewhat if needed. <br />If this doesn't cover all the information desired, please let me know. <br /> <br />William D.
