RECLAMATION PLAN resources, but rarely prevent the success of revegetation. Most native species that invade disturbances in abundance are not considered weeds as these species are often important in the process of developing new ecosystems. These native, weed-like species are rarely damaging although they may be unsightly. These natives should never be controlled without good reason. Topsoil - The upper portion of the soil that is usually distinguished as being darker in color than deeper portions of the soil. Overburden - Material between the topsoil and the sand deposit to be mined. For purposes of this permit, this also includes the subsoil component of the soil. Plant Growth Medium - Usually only includes topsoil, but in some instances may also include overburden: a. if the topsoil is limited in volume ornon-existent then overburden maybe included in the plant growth medium. b. where backfill is limited to only a foot or two and then capped with topsoil, the overburden used in the backfill is part ofthe plant growth medium. Upland -Upland refers to that land that is above the floodplain and outwash alluvial fans from valleys. Lowland -Lowland refers to that land from the base of the steeper slopes leading into the valleys to the drainage courses. The boundary between upland and lowland maybe abrupt in some places or more gradual in other places. (Note: These definitions are repeated in the Mining Plan and are therefore applicable and important to both the Mining and the Reclamation Plans.) LIST OF REQUIREMENTS - 1. In general, the requirements of this reclamation plan will apply to all lands mined prior to this amendment. Lands that were previously mined and reclaimed do not have to be redone using this plan, but all land that has not been reclaimed as of the date of approval of the amendment will be reclaimed in accordance with this plan. See page 9. 2. Backfilling must create a final surface that does not deviate more than 25 feet from the original surface elevation. The less deviation that can be created the better, but 25 feet is the maximum deviation allowed. (For a description of how the amount of elevation deviation is determined and monitored, refer to Exhibit E-2 - Monitoring and Compliance Methods.) See page 12. 3. If the bottom of the mining pit is already less than 25 feet below the original surface then backf"illing will include whatever overburden is available to return the final surface to an elevation as close to the original grade as possible.
