the smallest practicable area at any one time during ground disturbing activities. If rills and/or <br />gullies of limited areal extent form which disrupts the approved post mining land use or the <br />reestablishment of the vegetative cover they will be mitigated as soon as practical. Repairs will <br />also be performed in accordance with Rule 4.15.7(5)(a), which means they will be limited to no <br />more than five percent of the acreage initially revegetated during any one year. If a rill or gully <br />feature is identified, New Horizon will utilize appropriate manpower and equipment depending <br />on the ground conditions and the extent of the erosion. This shall include but is not limited to <br />small track dozers, blades, and rubber tired farm tractors. Equipment will be utilized to repair the <br />areas with a minimal footprint as possible. <br />Should an area need repaired that requires a more long term control method, New Horizon may <br />employ additional measures including erosion control blankets, straw wattles, silt fences, silt <br />fence like products, small riprap structures, mulches, small check dams, small rock structures <br />including rock basket(s) to reduce runoff volume. If repairs are required, all areas that have been <br />mitigated will be seeded with an appropriate approved seed mixture. If any of the above <br />mentioned sediment control measures are employed, they will be used inside the primary <br />sediment control systems or in conjunction with small area exemptions (SAE). These measures, <br />if necessary, will also not be implemented on any designed structures (i.e. conveyance ditches or <br />sediment ponds). <br />Special Features <br />Temporary Relocation for Colorado Cooperative Ditch Company - 2nd Park Lateral Ditch <br />The CC Ditch Company has the 2nd Park Lateral Ditch to irrigate land in the area for many <br />decades. With the mining of the Garvey & Co. property, this ditch was been diverted. Since the <br />temporary diversion route involved rises and dips, a pipeline was used. Map 2.04.7-9 2nd Park <br />Lateral Pipeline Location, shows the location of the pipeline's temporary and permanent <br />locations. A high density polyethylene (HDPE) pipeline was installed for the temporary route <br />and will also be used for the permanent route. <br />The pipeline temporary diversion route began at the eastern mine permit boundary, followed <br />County Road 2650 south, turned to the west around the permit boundary parallel to County Road <br />AA, then turned north along County Road 2600 to tie into the existing ditch. Now that mining on <br />the Garvey & Co. property has been completed, the temporary line can be moved to the <br />permanent location. The permanent pipeline will tie into the existing ditch west of County Road <br />2600 on the adjacent Garvey Brothers property as shown on Map 2.04.7-9. To accommodate <br />construction associated with tying the permanent pipeline into the existing ditch, Bench 1 <br />material will be hauled to the Garvey Brothers property as needed during final relocation. <br />Section 2.05.3(4) Page 4 March 2018 (TR -16) <br />
