Getches, Executive Director <br />MINED LAND RECLAMATION <br />DAVID C. SHELTO N, Director <br />March 12, 1986 <br />T0: Peter O'Connor <br />FROM: Steve Renner <br />RE: NATIONAL KING COAL HYDROLOGIC MONI70RING <br /> <br />DIVISIO N <br />As per your request, I have reviewed the water analysis and water level report <br />received from National King Coal (NKC). Below are questions and comments <br />which I feel are pertinent to hydrologic monitoring in general, and to the <br />King Coal monitoring in particular. <br />1) To determine the dominant chemical characteristics of the water <br />table in Hay Gulch, a "Baseline Water Quality" parameter list (see enclosure) <br />was included in the permit application. Unless a revision has been approved <br />by the Division, it is assumed that this parameter list is still in effect. I <br />would suspect that NKC will dispute this assumption, therefore I have marked <br />an 'X' (right hand column) opposite those parameters which I feel are <br />important. <br />2) Depth-to-water should be reported as feet below land surface. To <br />do this, NKC personnel should measure the distance from the top of the culvert <br />(casing) to the water surface. The distance from the measuring point at the <br />top of the culvert to the land surface should then be measured. The distance <br />from the measuring point to land surface should be subtracted from the <br />measuring point to water surface measurement. This figure is the distance <br />from land surface to water surface. <br />3) pH should always be measured in the field rather than in the lab. <br />pH is an unstable parameter, and should be measured immediately after the <br />sample is collected. The pH of a sample may change within two hours of sample <br />collection. <br />If you have further questions, please contact me. <br />srs <br />8360E <br />No;t : S~~ FrNAra(,s 7ocln.,.r..~ <br />w rt' c.a (L~~ou ~"~ n•.ON~ ,orcrn,e <br />3 <br />?e.omi,.,. r0 FE~,u Pee.An~-net <br />No W S~ ram SA,yvun. <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel.
