-2- (A) with the permission of National King Coal, Inc., the Roof and Floor analysis for arsenic (As), boron (B), manganese (Mn), selenium (Se) and zinc (Zn) could be incorporated into the La Plata Coal 14ine permit application. (B) analysis of the overburden material for the following parameters should be completed: pH, electrical conductivity, sodium absorption ration (SAR) calcium (Ca), magnesium (Mg) nitrate - nitrite, sodium (Na) and iron (Fe). A composite sample from the overburden may be obtained from the highwall cut, provided that only freshly exposed material is sampled. 4. Two pages of the Geology Description, 2.04-10 and 2.04-11, are missing from the permit application, and should be submitted for review. 5. Based upon the information presented on page 2.04-13r The drill log (figure 2) submitted with the application does not appear to represent conditions at the La Plata Number 1 Mine. The applicant should develop a stratigraphic column which describes the actual mine site. This column should be based upon the exposed strata at the mine site high- wall cut. Ground Water Hydrology (2.04.7) 1. A review of the National King Coal permit application indicates that a spring ("Huntington Spring") is located approximately 400 feet west of the proposed La Plata permit boundary. As this spring appears to be located immediately down-gradient from the La Plata Mine, the applicant should investigate: 1. Whether the spring does indeed exist; 2. Whether an application for water rights has been filed for this spring; 3. From what unit the spring eminates; 4. Baseline quantity and quality characteristics; and, 5. The potential impacts of mining upon the spring. 2. The permit application states that the Menefee Formation along the north side of Hay Gulch at the La Plata No. 1 Mine site is essentially dry. This interpretation is based upon outcrop observations in the vicinity of the mine, and the absence of portal discharges at this location. At this time, the Division concurs with the applicants' hydrologic assessment of the Menefee Formation at the mine site. The Division will not require that further hydrologic investigations of this formation be performed, unless significant quantities of water are encountered while mining.
