These data clearly show an aquifer in the Navajo Formation that is confined by a thick sequence of mudstones and claystone's in the Carmel Formation which overlies the Navajo. Lewis Lot 46 Well is completed in the Navajo and demonstrates an approximately 11 foot artesian head. Approximately 600 feet south of the Lot 46 well, the Lot 50 Well shows a SWL of 24 feet.Clearly the piezometric surface is confined by and does not cross the Carmel Formation.There are two piezometric surfaces; one in the Navajo and the other in formations up section from the Entrada. The Lot 51 Well is located approximately 900 feet south of the Lot 50 Well and shows a SWL of 100 feet. There may be no hydraulic connection between the Lot 50 and Lot 51 Wells, however,the SWL's suggest they may be located on the same piezometric surface and this interpretation is present on Figure-5. Permits to drill two other wells in the area (Forbes Lot 50 and Mead Lot 52)were applied for but there is no evidence either of the wells were ever drilled. The N-S Hydrologic X-Section is expected to represent the average ground water condition throughout the Skull Mine Permit area due to the continuation of the geologic formations which control the groundwater hydrologic regimes. Uinta Mining, LLC does not believe the mining plan will affect or interfere with the lower aquifer described above. But because of the water elevation reflected in in the Lot 51 well, UMC will drill and verify water aquifer location once mining reaches 50 feet above the projected water level elevation. These holes will be drilled 20 feet below the projected mining limits guaranteeing that the aquifer will not be intercepted by mining operations. If drilling intercepts the aquifer,the hole will be sealed using bentonite pellets. If drilling intercepts water level, mining of the sand block will end at 20 feet above that level. November 11, 2019
