MINING PLAN Upland Mining Processes Pre-mining Treatments: Although involved pre-mining treatments will often not be needed in upland areas, due to the general lack of noxious weeds being present, pre-mining examination must always be done. Pre-mining treatments aze intended to reduce problems in the reclamation, particularly with regard to weeds, and increase safety with respect to buried ordnance. About two weeks prior to the time an area is to be opened, the location and surrounding aeeas will be thoroughly examined. This examination will look at the soils and vegetation and check for buried ordnance to determine the appropriate pre-mining treatment required. a. During the pre-mining inspection, the site will be examined by Schmidt personnel who have taken the bomb recognition course for possible ordnance. If suspicious indications aze found those locations will be marked with a highly visible marker. GPS coordinates of the location as well as any other data relevant to identifying the location and estimated depth will be taken. Before disturbance actually occurs at the location where suspicious indications were found, the location will be investigated more closely by appropriate personnel from Shaw Environmental (current federal contractor) or other persons designated by the U.S. Army Corps of Engineers to remove ordnance from this property. Alternatively, in the event appropriate personnel are not able to check the location for actual ordnance, Schmidt will mine up to the suspicious location and then excavate cazefully, in accordance the required UXO identification training, and if ordnance is encountered, alert the appropriate authorities before mining further into that location. Mining where there are no indications of possible buried ordnance may proceed without further examination. Due to the possibility of buried, undetonated, and unstable explosive devices occurring most anywhere on this land, this procedure is important to protect the safety of mine personnel. This provision is required to comply with terms of the lease and to address liability issues. b. Soils will be examined to determine approximate depths of the salvageable layer and to look for any undesirable soils. Undesirable soils will rarely be found in upland areas, but they can occur. Undesirable soils are somewhat more common in lowland areas. More important, is determining the nominal depth for salvage. Scil depths maybe determined by examining backhoe holes, if Coal Creek Sand Resource Amendment 3 (2005) - M-1988-044 Exhibit D Page 24
