<br />• -z- • <br />locations are indicated for BC-8 and BC-15 but no logs are provided for these <br />drill holes. Please resolve these ommissions. <br />5. What are the sources (drill holes) df the samples used in the roof and <br />floor analysis of the Anchor and Cameo seams given in Attachment V, pages 5-2 <br />to 5-5? Data which should be supplied, in addition to that provided, for the <br />Anchor seam include: percent pyritic sulfur, percent total sulfur, percent <br />organic sulfur; and for both seams: chloride, fluoride, nitrate, sulfate, total <br />carbonate and boron. <br />6. What is the source of the bone coal data (roof, floor or interburden)? <br />41hat sample or samples and which drillhole(s) provided the sample for the data? <br />Please clarify. Also, supply an analysis of bone coal for the parameters <br />indicated in the Appendix. <br />7. .Please specify the units for available potassium content presented in pages <br />5-11, 5-15, 5-17, 5-19 and 5-21 of Attachment V. Also, resubmit all data given <br />to MEQ/1 converted to PPP1. Mercury content should be expressed in PPB. <br />~~ <br />8. Please show the locations of drillholes DDH No. lz and DDH No. 13 (indicated <br />on cross-section E-GEO) on Map A-GEO. <br />9. The applicant should locate any known faults, joint, or fracture systems on <br />a site-specific geology map. <br />10. The applicant should provide a composite analysis of interburden. (this <br />analysis should include all of the parameters listed in Item 5, section 2.04.6). <br />11. Map No. H-GEO presents a lithologic log for drillhole CM-4. This log indicates <br />that there is a 4' coal above the Cameo coal (which is the uppermost coal to be <br />mined). Because of the resource potential of this coal, the applicant should <br />discuss reasons why it is not to be mined. Rule 4.01.1(1) requires, "Maximum <br />use and conservation of the solid fuel resources being recovered so that re- <br />affecting the land through future surface coal mining and reclamation operations <br />can be minimized". <br />2.04.7 Hvdroloav Information <br />1. On page 3-4 of the application the applicant states that an NPDES zero dis- <br />charge permit has been granted for the operation. The Colorado regulations <br />require that sedimentation ponds be dewatered at appropriate times. To do this <br />the applicant will need an NPDES permit for discharge. <br />2. What is the location of the surface sample site for the analysis on pages 3-7 <br />of Attachment III? No reference is given for the drainage the sample was taken <br />from. Also indicate the sample location on Map No. FM-S-1-Hydro. <br />3. The applicant has provided a nearly exhaustive quarterly analysis of surface <br />and ground water. In addition to the parameters tested, however, the Division <br />recommends the inclusion of analyses for sulfide and nickel for ground water, <br />and nickel, aluminum, total suspended solids and total combustible solids (if <br />oil and grease or coal fines present) for surface samples. <br />4. Data taken at quarterly and monthly intervals for surface and ground water <br />must always include measurements of water levels or flow. This is required by <br />section 4.05.13. <br />
