mining vegetation quality that will be higher than what presently exists, will improve the relatively low quality wildlife habitat characteristic in these azeas. Topsoiling Due to the rocky nature (i.e., limestone outcrops) of the pre-mining landscape in the area, there is a limited amount of available topsoil in the area. Under present operations, as the quarry initiates a new mine cut, topsoil is recovered and hauled to designated topsoil stockpile areas (see Figure C- 2), where it is stockpiled and then seeded with quick growth grasses for the prevention of erosion. It is planned that, once the backfilling of Cut 2 is completed and the azea is ready for final reclamation, an area in the northeast comer of the cut will be designated for a topsoil stockpile for use in reclamation of the next cut. After the final grade of an area is reached, and prior to seeding, topsoil will be spread over the area. The thickness of the topsoil will vary from 0-6 inches, depending on the availability of topsoil and the amount of fine-grained material already present on the final surface. This system will continue as each successive cut is completed and reclaimed. By this method Holcim will also minimize the long term storage oftopsoils/A-horizon soils. Revegetation Based on input and recommendations from the Natural Resource Conservation Service (see attached correspondence), the following seed mix and planting rates will be used for revegetating the reclaimed areas.

Broadcast seeding will commence after final disking and contouring of an area, followed by cleating through the use of a dozer, and then fertilizing. Once this process has been completed, the area will be strawed for wind erosion protection and moisture retention. A noxious weed program will utilize chemical weed control in the event that noxious weeds start establishing in the affected land azeas that are not controlled by mowing. The general schedule and sequence for reclamation will resemble the mining schedule and sequence indicated in Table D-1. The typical size of the azeas to be reclaimed will average 25 to 30 acres and will coincide somewhat with the size of the cuts indicated in the Mining Plan.
