COOLEY RESERVOII2 AND FULTON WILDLIFE AREA PIT AMENDMENT NO. 1 - JERONIMUS PROPERTY EXHIBIT E -RECLAMATION PLAN This area of Amendment No. 1 is expected to be the final phase of the operation, and is intended to preserve existing open space/wildlife preserve areas in their natural state and create new open space/wildlife preserve areas. Areas that are not mined or disturbed will be left "as is". These areas will not be regraded or revegetated, but instead be preserved in their existing state. Within 1 year after all mining is completed, all disturbed areas and reclaimed slopes above those areas proposed for wetlands establishment shall be covered with 6"-12" + of topsoil prior to seeding. Any hard packed areas shall be scarified prior to the placement of topsoil and seeding. After backfilling, g.*ading of any area to final slopes, and placement of topsoil, seeding will be initiated as soon as possible. Maximum steepness of all slopes shall be 3H to 1 V. After placement of stored topsoil, areas not proposed for wetland revegetation areas shall be revegetated with non-irrigated grasses per the Cooley Reservoir Mix B from NRCS 01/28/03 letter to create uplands copied in EXHIBIT J -VEGETATION INFORMATION. This grass seeding shall consist of the following: SPECIES VARIETY PLS# PERCENT PLS#/AC Pubescent wheatgrass Luna 9.0 20.0 I.8 Western wheatgrass Arriba or Barton 8.0 30.0 2.4 Blue grama Hachita or Covington 1.5 10.0 0.2 Sideoats grama Vaughn or Butte 4.5 30.0 1.4 For wetlands creation, partial reclamation will begin with the backfilling of sediments created during the processing of the mined sand and gravel. At the termination of mining, at least 50% of the presently exposed lake area is expected to been bac~lled to a level to support wetland vegetation at the conclusion of all mining. Interim planting of wetlands vegetation shall be undertaken, whenever a minimum of 5 acres has been filled to within 3' to 5' above the original lake surface. Created wetlands in excess of what is required to be created per an approved Corp of Engineer's 404 Permit on this property may be utilized as replacement wetlands on others sites in accordance with approved Corp of Engineer's 404 permits on other sites.
