Mr. Dave Canning <br />Page four <br />April 15> 1982 ~ ' <br />2.04.7(b) Surface Water Hydrology <br />The applicant's inventory of surface water bodies is <br />incomplete. The applicant should submit a map (Rule 2.04.5(4)) <br />showing all reservoirs, ponds, ditches, springs, etc. located <br />in or adjacent to (1 mile radius) the permit area. The <br />Division is particularly concerned with ponds overlying the <br />underground workings, springs overlying the underground <br />workings or downdip from the mining activities and <br />irrigation systems. <br />2. Depending upon [he results of the probable hydrologic <br />consequences of mining evaluation of Middle Creek, it may <br />be appropriate for the applicant to supply alternative <br />water supply information for appropriated water uses. <br />3. The surface and ground water monitoring can now be amended <br />as per attachment A, because the Division has reviewed the <br />possible water from mining within the Yampa River Drainage <br />pollutants. Total hardness and total iron should be added <br />to the surface water parameters and dissolved iron should <br />should be added [o the ground water parameters. The <br />The following parameters may be dropped from the list: <br />Alkalinity, Vanadium, Orthe-phosphate, Barium, Chromium, <br />and Nickel. Frequency of monitoring may also be reduced as <br />suggested in Attachment A. Further reductions in monitoring <br />may be possible upon petitioning the Divisions with <br />appropriate justification. <br />2.05.3 Operation Plan Permit Area <br />1. It is unclear from the information presented in the application <br />what seams are to be mined during this 5'Year permit term. <br />The applicant should supply an anticipated sequence of mining <br />in both narrative and map form. This information must describe <br />anticipated starting dates and termination dates for each <br />phase of mining for each seam to be mined. Anticipated annual <br />production must also be provided. <br />2. The drainage from the gulch behind the office seems [o be <br />diverted. This drainage must be delineated down to its <br />confuence with Trout Creek. If the flow has been diverted in <br />the office area, the designs for the diversion in accordance <br />with Rule 4.05.3 must be supplied. <br />
