Extraction and Reclamation Operations Presently, Tract A is the area of active resource recovery, while plant operations and stockpiles occupy the majority of Tract B. The affected lands, evident in the July 2006 aerial image, remain closely representative of the location as it is seen in 2009. The observed differences are updated by graphical interpretations, as determined by field measurements and objective references on the ground, as illustrated over the 2006 baseline aerial and attending data. Activity in Tract C should be comparatively short lived. Operations will gain access into Tract C from an existing access point on the northeast corner of the location as seen in the included aerial image. Two discharge points may be used individually or in tandem, however, waters will exit near the newly designated DPC on the northeast corner as it drains into a lower existing pond whose waters can be further detained and settled before being released by developed gates and drainages into the adjacent wet meadow, as historically practiced. Extraction will follow within 25± feet of the existing tandem wells, consistent with previously approved setbacks for this location. The extracted area will be concurrently backfilled to 100± feet from the center of the well, comprising nearly 0.62± acres of fill. From there the extraction will either follow the perimeter and sweep counterclockwise around the location, or else open up a gradually increasing pit wall and work the site from the northeast to the southwest. Either method will follow with the use of bottom shale material to establish 3H:1V finished slopes, and capped with a minimum of 0.5± feet of soil. Soil will be stockpiles initially on the backfilled area and later utilized in an over the shoulder method to cap the completed basin slopes remaining above water. With approximately 2.40± acres of above ground area requiring revegetation with the previously approved seed mixture, approximately 1,936 cubic yards of soil will be required for completion of resoiling of affected lands remaining above the anticipated static water level of 4785± feet. Financial Warranty Determinations Reclamation over the adjacent Tract A has progressed to a point where the planned activities for Tract C should be covered by the resulting excess warranty coverage already in place for this permit and related approved activities. We will rely upon OMLR field verification of this assertion.
