EXHIBIT E RECLAMATION PLAN **Amendment - 1 May 07 Rule 3434.5-t6tEA.5 (1) Final grading the entire NORTH QUARRY shall be to extract the resource to an essentially flat base elevation approximately 24 feet below the bottom of the pre-existing quarry floor. No reclamation can commence until the third bench (elevation) is extracted. Drainage from the site will be minimal due to the low precipitation expectation of the region. The flat slope of the pit floor will tend to retain and disburse any received precipitation or runoff from the back-slopes for the consumptive use by the plant life of the re-vegetated bench. A small berm of fines material shall be placed at the throat of the mesa wall opening to prevent runoff spillover. The back-walls of each of the three extraction benches shall have been drilled and shot to a nearly vertical (approximately '/4-H to 1-V) stable bare slope, where erosion is not a factor in the extremely hard sandstone. Stepped benches of 6 to 12 feet wide shall be left in the backwall at approximately each 12-foot vertical elevation increment. ... 6.4.5(2)(a) Reclamation chosen for the **extraction areas of the entire site, including both the NORTH QUARRY (17± ac) and SOUTHEAST QUARRY (3. ac), ''*eaclusive of the staging/stockpile! storage yard, is a return of the premises to rangeland, since no other alternative is practical. The lack of significant soils to cover the pit floor, the lack of available water resources, and the hardness of the pervasive bedrock preclude any consideration of building sites for residential or commercial purposes. The site would be suitable for an industrial storage yard, but the site is not currently close enough to such activity to be useful for the present. **Reclamation chosen for the "Office Trailer", "Parking", and the new adjacent additional stockoile/storage/staging area shall be to leave an un-fenced, un-vegetated flat-graded IndustriaUCommercial construction staging, storage, and oarkina vard. Any paving or gravel surface grading, as well as stored materials, vehicles and temporary enclosures shall be left intact for continuing construction operations use of the current landowner. (b) The only other such extraction quarry in the vicinity is on neighboring lands located just south and east of the proposed site, is known as the Four Comers Materials Hindmarsh Pit site. It has been restored to rangelands and wildlife habitat, and some pre- mining law azeas have reverted to such, whether by conscious reclamation effort or re-vegetation of the disturbed sites by neglect and natural processes. (o What little stockpiled material (composed of surface soils, vegetative matter, and loose surface rock, which was stripped from mining and process azeas) shall be spread on the pit floor with any reject fines soils remaining from the rock processing. Thin un-retrievable soils left on the surface before initial drill & shoot extraction operations are not lost since they become a part of the processed reject fines that will be utilized as vegetative growth media following process & stockpile operations. (e) Reclamation surface preparation shall be delayed until each of three bench elevations has been extracted and the pit floor areas aze no longer needed for current process/stockpile operations. The following table is an idealized example assuming a constant rate of extracting several half- acre shots each year. Actual production and market demand may significantly alter this hypothetical example. ExrRac7EO "OR USE AREA EXC.
