Most of the operation <br />remains much as it was last year. <br />Annual Report Maps: Enclosed are three color maps showing the primary areas of disturbance and the type <br />of disturbance occurring in each area. Map 1 shows the entire site and is primarily a guide map. Maps 2 includes <br />the Main Quarry portion and Map 3 shows the information for the Cut Stone Quarry area. For details of <br />acreages please see the maps. <br />Affected Lands: The amount of affected land in the operation technically showed an increase. All of this <br />increase is contained in the expansion southward of the Main Quarry less the amount of new land placed in <br />final reclamation. A new area of reclamation has been completed with backfilluig and is being topsoiled and <br />prepared for seeding in May of this year. This will increase the amount of land in full reclamation and will <br />roughly balance the expansion with the reclamation. The Cut Stone Quarry area showed no changes. <br />Revegetation: Past revegetation efforts showed good progress. At this point it appears that it takes from 3 to 4 <br />years to produce excellent growth comparable to the undisturbed land (see photos). Species diversity is less on <br />the reclaimed land. However, invasion of the fortis that increase diversity on undisturbed land are invading the <br />reclaimed land. Both wind and water erosion control on reclaimed land is excellent. Past weed control efforts <br />have been very effective with only minor amounts of weed growth present in isolated locations where <br />previously the weed density was high. First year growth tends to be somewhat weedy, but the annual weeds <br />decline in the second year and, with treatment, most of the remaining weeds are eluninated by the third year. <br />From there on it is simply a matter of weed control maintenance of the few that persist. <br />Expected Activity (2008/2009): The Cut Stone Quarry will probably change very little. The main quarry may <br />expand a few more acres to the south and then west toward the large powerline. Future mining will probably <br />occur only in Phase 2. Additional backfilling in Phase 1 will occur as overburden becomes available. <br />Photos: A series of photos primarily showing the reclamation areas are included. As evident in the photos, <br />blending of the backfilled land into the undisturbed adjacent land is excellent and has essentially returned the <br />land to its original topography. <br />Bonding: This operation is covered by a self bond <br />M-1989-065 Winkler Light Aggregate Quarry <br />Schmidt Construction Company 2008 Annual Report Page 1 of 1 <br />
