Mr. Robert F. T. Krassa -6- March 24, 1994 <br />the necessary correction. We will notify you as soon as the newly-corn~ted maps are <br />submitted. <br />8. A map describing the lateral extent and pay thickness of coal seams underlying a <br />permit area is not required by our regulations. Rule 2.04.6(3)(a) requires the <br />application's geological description to include information of the geology "within the <br />proposed area to be affecxed over the life of the operation" (emphasis added). For <br />that area, Rule 2.04.6(3) requires the application to include cross sections that <br />describe the nature, depth, and thickness of the coal to be mined, as well as each <br />overburden stratum and the stratum immediately below the lowest coal seam mined. <br />The Division has anon-proprietary cross section that shows this information, as well <br />as a map indicating the location of the test holes from which the information for <br />developing the cross section was obtained. The holes within Rancho Escondido that <br />made up Cross Section B-B' (maps 5 and 6) are located in the SFJ4 of Section 8, the <br />lVFJ4 of Section 17, the SFJ4 of Section 17, and the NW/4 of Section 20, all in <br />T33S, R67W. <br />A map showing the extent of expected surface subsidence effects has also been <br />submitted. This map is entitled 'Structure Inventory, Map 20". <br />We hope these comments provide satisfactory msponses to your letters of <br />February 22 and 24, 1994. Please let us know if we may be of further assistance. <br />Sincerely, _ -.. . <br />Daniel I.
