Geology <br /> 7. Page 2.04.6(15) of the application references a report by David Gaskill <br /> of the U.S.G.S. pertaining to geologic hazards and ground water as <br /> Exhibit E. The referenced exhibit could not be located in the <br /> application on the Division files and should be submitted, if available. <br /> In addition, Menefee Land Company drilling program data referenced on <br /> Page 2.04.50 1 ) could not be located and should be submitted for <br /> inclusion in the application if the revision area was included in the <br /> drilling program. <br /> 8. The only drill log included in the application is from a core hole <br /> located in the existing permit area within the SE 1/4 NW 1/4 of <br /> Section 32. No drill logs have been submitted for the 480 acre extension <br /> area. The Division generally requires a minimum of at least three drill <br /> holes to adequately characterize the lithology, physical properties and <br /> thickness of potentially affected strata, location of subsurface water if <br /> encountered, and chemical properties of coal , roof and floor materials, <br /> and partings if encountered. <br /> Lithologic logs and data obtained from at least two additional core holes <br /> within the proposed revision area will need to be submitted to address <br /> the requirements of Rule 2.04.6(3)(a)(iii)(A)-(E), unless NKC can <br /> demonstrate that such information is unnecessary pursuant to <br /> Rule 2.04.6(3)(b). A structural map of the top of the coal seam will <br /> need to be included on the mine plan map for the revision area. The map <br /> will also need to show drill hole locations and coal outcrops and <br /> subcrops. <br /> 9. Roof, floor and coal samples should be obtained and analyzed as <br /> recommended in the Division' s September, 1982 Guidelines for the <br /> Collection of Baseline Water Ouality and Overburden Geochemistry Data. <br /> In addition, at least one composite sample should be obtained from <br /> portions of the existing coal mine waste pile which have been exposed to <br /> the atmosphere for at least one year, and analyzed for the same list of <br /> parameters. <br /> Ground Water Hydrology <br /> 10. A "Hydrosearch" document addressing ground water developments in the area <br /> referenced on Page 2.04.5(11 ) could not be located in the Division <br /> files. A copy of this document should be submitted for inclusion in the <br /> application. A description of the ownership, uses and location of any <br /> wells or springs within the revision area or adjacent area not previously <br /> identified in the permit application will need to be provided, along with <br /> a description of the inventory methods pursuant to Rule 2.04.7(1 ). <br /> 11 . A statement on Page 2.05.6(22) regarding the presence of water in <br /> overburden strata contradicts other information in the application. If <br /> the statement is in error, it should be corrected. <br /> -2- <br />
