(Page 2) <br />MINE ID # OR PROSPECTING ID # M-1995-026 <br />INSPECTION DATE 8/24/05 <br />INSPECTOR'S INITIALS RCO <br />This inspection was performed by the Division as part of its monitoring of Construction Materials 112c permits. The operator <br />was contacted about the date and time of the inspection. The operator's representative named on page one was present <br />during the inspection. The site was identified by the required permit ID sign at the entrance gate. The affected area <br />boundaries are marked by fencelines and markers. <br />The site was not active at the time of the inspection. The pit floor contains several stockpiles of various materials, and a couple <br />stackers and small crushers. AI activity appears to be contained in the Phase 1 area, as approved in the permit. No <br />hydrocarbons are stored onsite. There is no debris or contamination on the site. <br />Some of the disturbed areas exhibit healthy annual weed growth, which appears to be be effectively controlled or managed as <br />ongoing reclamation is carried out. The west wall of the pit is in its final configuration: 3:1 slope, topsoil replaced, erosion <br />controlled, and good revegetation with no weeds. <br />The north wall and east wall are sloped at 3:1 also, to ensure better stability until they are disturbed again. (The pit slopes are <br />mined at 3:1, which improves stability and reduces reclamation needs throughout mining phases.) The north wall is not in its <br />final location, and will be moved northward into Phase 4. The east wall will move eastward into Phase 2. Because they are <br />temporary, neither of these slopes have topsoil replaced or revegetation. The slopes contain some annual weeds, butjudging <br />by the successful reclamation (i.e., weed control) of the west wall of the pit, this is not a problem. <br />The topsoil pile is in Phase 2, which has not yet been mined. There is a part of the surface on the north end of the pile that <br />exhibits recent disturbance (removal for topsoil replacement?)and it should be graded to a gentler gradient and seeded to keep <br />the annual weeds down. Keeping the weeds down while it is stockpiled will make the job of keeping reclamation areas (where <br />the topsoil is replaced) weed-free easier. The operator is reminded that wherever possible, placing topsoil on areas to be <br />reclaimed as soon after it has been stripped elsewhere (by either minimizing or eliminating its time in stockpile), increases <br />revegetation success since soil viability is maximized. <br />The south end of the pit floor contains a stormwater control berm, which appears to keep runoff and sediment from entering the <br />drainageway south of the pit. There was no evidence of runoff water gullying the native slope below the pit floor or impounding <br />in the drainageway, or of sediment being transported below the pit. <br />The operator stated that good aggregate is believed to possibly extend much deeper, and that after the current phases are <br />mined down to the present (Phase 1) floor level, a second round of deeper mining might be considered. Since this is not part of <br />the existing mining or reclamation plans, it would require a technical revision to the permit before it was undertaken. <br />No further items were observed during the inspection.
