above the seams to be mined should be included in the application. The application defined the thickness of the five upper seams; the Rex Carbon, the Manley, the Vento, the Black Hawk, and the Dirty Jack O'Lantern, but the attachment ZV or Appendix A and B which would define their nature and depth were not supplied. 2.04.6(2)(a)(i) 2. The geology map of the permit area is incomplete. All faulting and fracturing must be identified on this map. Also on this map coal outcrop lines should be provided. The crop lines on maps DOR-E-GEO, DOR-F-GEO and DOR-G-GEO are not accurate or complete. In addition, any crop lines in the southwest must be provided. Appropriate strikes and dips should also appear on the geology map. 2.04.6(2)(a)(ii) 2.04.7 Hydrology Description Ground water information r 1. More baseline information is required on the qualify and quantity , of water in the Trinidad Sandstone. What wells in the general area utilize this aquifer as a source of water? What..are the production rates in these wells? What is the quality of the water and what use is made of the water? 2.04.7(1) The units within the Vermejo, the Raton and Poison Canyon Fofmations which store and are capable of transmitting ground water must be specifically identified and discussed. These aquifers are of concern because of the static water level of 6,100' in the old workings and the fact that water was encounterd above the coal seams in most of the drill holes. A contour map of elevations and units in which water was en- countered and a study of the correlation of these units must be supplied. 2.04.7(1) In addition, a water monitoring plan must be supplied. (see section 2.05.6) 2. Figures 5 and 6 list water rights in the vicinity of the permit area. What uses are made of the water from these sources? Where does Dorchester obtain potable water sources for their mining operations? This information is necessary to establish the hydrologic balance and what water supplies might be impacted by mining. 2.04.7(1)(a)(iii) All of the sources of water plus all ground water monitoring stations must be located on the hydrology map. (see 2.04.7(4) 3. Insufficient documentation of the recharge, storage and discharge of the aquifers on the property, has been supplied. After the water monitoring plan, which sould include pump tests, is supplied, this can be evaluated. 2.09.7(1)(b) (see section 2.05.6(3) regarding water monitoring) (2)
