Scrrim - 2.05.3 • Soil is recovered from stockpile for placement following final grading of reclaimed • disturbance areas. The regraded surface is roughened and scarified to provide a good bond between the soil and underlying materials and to promote moisture infiltration and root penetration. The surface of the replaced soil materials u left in a roughened condition to promote infiltration, minimi,r rung{{ and provide a good seedbed for revegetation. All available stockpiled soil materials will be utilized in reclaiming mine disturbance areas. Replaced soil materiak and the underlying graded overburden materiak will be sampled to a total depth of 3 feet az the basis for evaluation of suitability and selection of any appropriate soil supplements. Overburden Because the OMI operations are limited to underground muting, information requirements for overburden removal and handling plans are not applicable. In conjunction with surface facilities development and construction, however, occazional blasting activities maybe required az addressed in the following sections in compliance with applicable provisions of Rule 4.08. This blasting plan addresses those procedures utilized for the occasional surface or underground blasting required in conjunction with ongoing underground mining and related support operations. Generally, blasting is limited to fragmentation of rock materials so that they can be excavated during mine development or facility and road construction; fragmentation of large rocks which may roll downslope into active operating areaz; fragmentation of rocky material which may become hung-up in the coal handling system; and demolition of concrete foundations and structures in conjunction with facihties modifications or reclamation. Each blast is documented by a blasting record prepared by or tinder the supervision of the individual • responsible for blasting operations. Blasting records are rrrairttained at the mine site for at least three yt:ars and are available on request for inspection by the DMG or the public. Blast records include the following specific information: • Operator name • Location, date, and time of blast • Name, license number, and signature of Licensed Blaster in charge of blaring operations • Description, direction, and distance in feet from blast to the nearest structure, dwelling, public building, school, chtuch, or commuairy or institutional building • Weather conditions including temperature and wind speed and direction • Type of material being blasted • Sketch of blast pattern(s) showing number, diameter, and depth of holes; burden; spacing; delays; and decking (if any) • Type of explosives used • Total weight of explosives used and maximum weight per 8-millisecond delay • • Blat initiation system • Type and length of stemming PR04 2.05-39 Revised August 2000
