Mr. RiDbert F. T. ICrassa -3- March 24, 1994 <br />aquifer was identified below the coal in the geology description. <br />From discussions with Basin Resources regarding mine water inflow, it is our <br />understanding that significant inflows of water entering the mine from below the <br />active workings occurs south of the 1'urgatoire River only. Basin Resources has not <br />seen any similar inflows into the mine from beneath the workings in the area north of <br />the river. <br />Basin believes the inflow into the mine's workings south of the river is from a fault <br />or fracture wne, rather than a stratigraphic unit. They do not ]mow whether the . <br />inflow is from the Trinidad Sandstone. We have a"~~ R""~^ ~^ °~-~^^~ra <br />whether the Trinidad Sandstone in the Rancho ]iscondido area will be affected by <br />m~rmn' g noi~bf'thd'rfver- - - - - _-- - -- -- - - - - - <br />6. We cannot draft provisions to any permit in the anticipation of proposed Federal <br />regulations. Permits issued by the Division are required to be in compliance with <br />only those State statutes and regulations existing at the time of the proposed decision. <br />Should any Federal regulations be developed in the future affecting coal mine <br />reclamation, be assured the Division will promulgate similar State rules, and require <br />operators to comply with them. <br />7. We would like to address two points from the January 1994 document prepared by <br />Carlton Gerity entitled 'Report Concerning the Effects of Underground Coal Mining <br />on, the Rancho Escondido Estates". This was included in the February 22, 19941etter <br />as Bxhibit 35. -- - - - _. _ - <br />The first point is with regard to the comments in the conclusion on page 2 regarding <br />the. Rancho Escondido subdivision. In this conclusion, it is stated that meetings were <br />held between representatives of the Division and Raton West in December 1993 and <br />January 1994. It is further stated that 'as a insult of these meetings, the Division has <br />agreed to classify the Rancho Escondido as renewable resource lands ..." <br />This is incorrect. The Division does not believe the Rancho Escondido subdivision <br />should be classified as a renewable resource land. <br />The second point is with regard to the diagram on page 5. This diagram indicates <br />that the "Angle of Draw" is drat angle measured between the outside edge of the <br />S~ ~ ~~ "cone" of subsidence and the top of the coal seam. <br />TLis is also incorrect. Using the page 5 diagram, the correct definition of "angle of <br />draw" is that angle between an imaginary vertical line drawn from the outside edge of <br />a panel to the surface and the outside edge of the "cone" of subsidence. This is a <br />
