<br />COMMENTS ON DRAFT FINDINGS <br /> <br />1. The stlpulatlon now specifies that sediment control structures are the <br /> pot entially non-complying structu res. The rationale for the stlpulatlon <br /> is stated on page 13 of the draft ftndings. <br />2. An up-to-date coal ownership map is provided as Drawing No. 203.4(5)-2 <br /> 1n volume 7 of the application. The map does show Federal Coal in the <br /> SWl /4, SW1/4 Section 12, which is leased to Grand Mesa Coal Company. <br />3. The document has been modlfted as requested. <br />4. The document has been modified as requested. <br />5. The document has been modified as requested. <br />6. a. A discussion of the "D" seam analyses has been added on page 12. <br />b. The analyses presented in Appendix A of Volume 10 are for the "D" <br />seam, not the "E" seam. The consultant's report in Volume 10 <br />incorrectly refers to "E" and "F" coal seams, rather than "D" and <br />"E" coal seams. Since the "D" seam outcrop is approximately 100 <br />feet stratigraphlcally below the "E" seam, and the "D" seam outcrop <br />is several hundred feet to the south of the "E" seam outcrop, <br />analyses provided should be representative. The applicant has <br />revised Appendix A to point out the seam identification error. <br />c. "E" seam sulfur analyses were submitted in the May 8, 1981, reviston <br />to Volume 2 of the application, but the table was not clearly <br />labeled. (See table Tabled 2.04.6(2)(a)(1v)(D) Included 1n Volume <br />12.) "D" seam roof, floor, interburden and coal analyses are <br />contained in Appendix A of Volume 10 of the application. <br />7. The document has been modified as requested. <br />8. Stipulation No. 1 has been modified. <br />9. The document has been modified as requested. <br />10. a. The ground water monitoring requirements have been clartfted and <br />stipulated. Annual monitoring for pH, EC and temperature has been <br />stipulated for deep rock and alluvial wells. <br />b. The "expected rise in TDS described on pages 23 and 24 borders on <br />'material damage'" to potable water supplies. Grand Mesa's plan <br />addresses replacement of potable water supplies by means of the <br />Colby domestic water system. The recently submitted Volume 12 <br />provides additional details regarding the replacement plan and, as a <br />result, draft stipulation No. 8 has been deleted and the text of <br />Section VIII of the findings document has been revised. <br />
