EXHIBIT E RECLAMATION PLAN (CONT) TIMETABLE-OPTION B for information on each Option and Phase changes for the Reclamation. The areas of the mine site that are not currently involved in the mine operation are primarily irrigated agricultural land, which is broken into 5 different use areas . The uses are, irrigated crop areas; non-irrigated pasture; ditch and return flow corridors; and also oil/gas operations areas with some high capacity gas pipeline ROW' s . The agricultural uses will continue in areas where mining operations have not yet begun. There is very little native vegetation present on the agricultural areas because of the intensive agricultural practices that have taken place on the land. In most cases, the oil/gas operations areas have little vegetation and the high pressure gasline ROW' s have been farmed for many years and the vegetation cover on those areas is consistent with farmed areas . The narrow bands along the Cannon return flow ditch, the Platte Valley Canal and the Platteville Ditch have been consistently disturbed by ditch maintenance. This leaves only isolated areas around the permit area with vegetation that may be considered native. The typical vegetation descriptions in EXHIBITSI&Jwill not match the actual current vegetation since the practice for the agricultural activities are that crops are rotated from year to year. RECLAMA TION PLAN FOR RESER VOIR AREAS This section covers reclamation on the developed water storage reservoirs in Phases 1 thru 6. As discussed in the Mining Plan text, reclamation will run concurrent with mining. Initially this will happen when the reservoir slopes area is being mined and graded. The plan is to leave undisturbed natural sand and gravel at 3v: lh slopes in each reservoir phase. The 3h to lv slope of natural, undisturbed materials will need no other reclamation except minor grading to dress the slope. On the armored areas a dirty sand and gravel (unprocessed) will be spread over the armoring to fill most of the large voids . Since the perimeter of the reservoirs will be mined to their final (3H to 1V) slopes, only minor amounts of slope work will be necessary as mining ends . This will also insure, that if mining ceases before the resource is exhausted, only a minor amount of work would have to be done to finish reclamation on the disturbed area. At this time, the final reservoir levels are estimated to be at the lowest crest elevation around any given reservoir. The temporary topsoil stockpiles in the various mining phases will be available for reclamation needs . When grading and shaping is completed on the section of reservoir banks and slopes inside the slurry walls, reclamation L.G. Everist, Inc. Ragsdale Reservoirs Revised February 11, 2025 23
