the northe~~st with the Arkansas River receiving all surface water <br />flows. Sm<~II ephemeral and intermittent drainages parallel the <br />slopes. Soil materials are generally poorly developed sandy loams <br />derived from surficial colluvial/alluvial materials (Exhibit I). The mine <br />site lies wii:hin an arid vegetation region including many species of <br />cacti and native arid grasses (Exhibit 7). <br />Environmental resources are minimal due to the aril climate, <br />approximai:ely 13 inches of rainfall per year, and lack of water <br />resources. Adjacent land in Sections 12 and 13 contain gravel mining <br />operations. The land is not capable of supporting agriculture due to <br />sandy loarri soil and minimal water. <br />Two historic mining areas lie within the permit area, the Chandler <br />Mine in the southwest corner and the Brookside, Prospect and Canon <br />City coal mines in southern portions of Sections 10 and 11 to the <br />northeast shown on Map 4, Extent of Abandoned Mine Workings. The <br />aforementi~~ned mines were underground mining operations with <br />surface operations located outside the proposed Northfield permit <br />area. Minimal reclamation was performed at these sites. The mining <br />method for all historic mines in the area was room and pillar. <br />• Coal Mines Located within the Northfield Area (Exhibit H~, <br />~V~ ~~ <br />~~~ <br />~\ <br />[7 <br />OCEAN W/~-VE SEAM <br />Mine Name Sec T R Dates Tons Produced <br />Blue Flame 12/19/70 1939-1942 2 098 <br />Canon Ci 11/19/70 1934-1951 39 786 <br />Golden Quality <br />#2 12,13/19/70 1947-1952 9,602 <br />Golden Quality <br />#3 12,13/19/70 1952-1956 14,581 <br />Griffiths 18 19 30/19/70 1922-1955 403 944 <br />BROOKSIDE SEA M <br />Boulder Canon 11/19/70 1934-1937 3 048 <br />Brookside 10,11,14, <br />15/19/70 1893-1960 2,075,125 <br />CANON SEAM <br />Fremont 24 25/19/70 1883-1942 2 788 353 <br />Rockvale #2 24/19/70 1899-1934 4 696 166 <br />CHANDLEF~ SEAM <br />Chandler 14-27/19/70 1890-1942 5 149 996 <br />ROCKVALE° SEAM <br />Rockvale #:i 24 25 19 70 1883-1893 2 053 948 <br />2.04-2 <br />
