(Page 2) <br />MINE ID # OR PROSPECTING ID #: M-1977-345 <br />INSPECTION DATE: 6/19/09 INSPECTOR'S INITIALS: ECS <br />OBSERVATIONS <br />This was a routine monitoring inspection for an active 110c sandstone quarry operation conducted by Eric Scott <br />of DRMS for the Boettcher Sandstone site. DRMS met with site operator representative Michael Toelle on site <br />at approximately 1045 and toured the site with him. <br />The required site entrance postings and site boundary markers need to be refreshed and/or replaced as no site <br />entrance sign was present. <br />Mining has not taken place at this site at in quite some time, and the site has not been put into temporary <br />cessation. It should be noted that the rule states that reclamation should be completed within five years after <br />mining ceases unless the site is put into temporary cessation. No reclamation activities have been completed at <br />the site to date, and weed control efforts will need to be implemented as soon as possible to keep noxious <br />species from establishing/spreading any further. <br />The reclamation plan for this site dates back to 1978 and calls for blending the site with the adjacent land with <br />slopes of 2:1 or flatter. Soil that is encountered will be re-spread and the area revegetated. The currently <br />approved seed mix consists of Needle and Thread, Little Bluestem (5 lbs/ac PLS), and Indian Ricegrass (8 <br />lbs/ac PLS). <br />Some earthmoving work will be required to reconfigure slopes to 2:1 or flatter where possible. A Technical <br />Revision JR) to the 1978 reclamation plan will be required if the access road is to be left in place, or any of the <br />highwall features are to remain on site. If highwalls are to remain on site after reclamation, it will need to be <br />demonstrated that they have been adequately stabilized. The seed mix may also be updated via the same TR to <br />a more current blend if desired. <br />I & E Contact Address <br />Michael Toelle <br />Holcim Inc.
