BOX 46 MONTE VISTA, CO 81144 852-4781 <br />;• <br />o~t^FIVED <br />DEC 2 9 1995 <br />December 21, 1995 <br />~7 <br />374 GRAVEL °IT td-~.8-020 <br />Division o; tviinerals & Geology <br />1, 6.4.3(f) There is a small irrigation ditch paralling <br />Rio Grande Lateral ~fl just inside the pit fence. It <br />should not be affected by the mining operation. It is <br />not known if there are any wells that would be affected. <br />2. 6.4.3(g) Rio Grande County does own the fencing and the <br />higho7ay along the south side of the pit area. <br />3, 6.4.4(b) Earthmoving <br />The equipment used in excavating the material in the 374 <br />pit has been a front end loader. It was used to feed the <br />crusher plant by a private contractor. <br />4, 6.4.4(c) There are no water diversions at the nit. The <br />ground water shows un in the pit when the canals are turned <br />on in the summer. In the fall and winter, the nits dry up. <br />There are two small ponds at the nit caused by the crusher <br />operator digging to deep. There is not any material excavated <br />while there is water in the nit. <br />5. 5.4.4(e) The direction of mining operation for the nit is <br />from west to east. The small pit towards the east side <br />which was used by the Town of Del ?Norte was mined from <br />north to south. <br />6. 6.4.4(f)(i) It is limited to 10 feet. <br />7. 6.4.4(f)(ii) The material immediately beneath the mined <br />area is sand and gravel. <br />8. 3.1.9. Tonsoiling <br />At the present, there has been very little topsoil stripped. <br />The area that has already been mined has a very thin layer <br />of topsoil which most has been incorporated in the crush- <br />ing operation. Rio Grande County has hauled topsoil to <br />the pit to stockpile and add an additional amount to the <br />crushed material. The 374 pit is realitively flat so I <br />would assume that this area was leveled at some time and <br />most of the topsoil has been moved to the easterly Hart <br />of the pit area. This indication seems to show up in <br />the smaller pit on the east side of the property. The <br />stockpiles that are there seem to be hardly affected by <br />water or wind erosion. They revegatate with weeds and <br />there is very little rain fall to cause water erosion. <br />v <br />;> <br />:~: <br />r <br />
