COLORADO 81301-6928 (303) 2470088 David Shelton, Director Mined Land Reclamation Hoard 1313 Sherman Street Denver, Colorado 80203 Ref: File M-RO-143; Texas Creek Gravel Pit I have reviewed information provided me by Terry Sadler on the above gravel operation. In particular, items on which an engineer may be asked to comment are those of the physical adherence to the mining and reclamation plan and the ability of the operator to accomplish those plans. The gravel pit at present is in the operation mode and estimates must be made about the final status of the land for reclamation. In order for me to comment fully, it would seem very obviously necessary to have a plan of the site, showing operations, intendec9 disturbed land, etc. This is in fact required by your application procedure and described as Exhibit C. There i:> no Exhibit C, or map, in the application available at the La Plata County Clerks office. Your application process states ghat an applicatiod will not' even be reviewed, mach less approve(1, without all o€ tlhe required Exhibits. Thus thE~ comments II makd here are based only on the very brief narrative included lin dhe application and on actual site information of topogdaphylprovided me and under my supervision. The site as it exis$s togap is not being mined with a 1.5 H to 1 V slope as Exhibit IB stlates. Because of the rapidly rising backslope behind the mining face, as the amount of matezial removed increases, the difficulty of retaining the proper slope increases. It is unllikelyl that final slope reclamation, an item which even the MLRB Imay hpve trowb$e.determiging without al map and plan, will be malde im~ossible~tb any reasonably stable grade due to property line roost aints and lack of overburden material. The cost of reclaiming Ithis area, returning the topsoil and reseeding, as a mini>sium, wlill probably exceed $5,000. The recommendation of Bob Hawn, of the SCS (also in your application) states that 3:1 is a recommended slope for reclamation. In addition, Hawn recommends that the area is to be protected from vehicles, people and livestock until reclaimed, obviously the 3:1 lslopelI recommended in the application is impossible, given thelappa#ent progress of the work face.
