Rule: 2.04.10 Vegetation Information <br /> 28 February 2023 <br /> DRMS understands that the expansion area comprises grazing rangeland consisting of Big <br /> Sagebrush and grassland vegetation types as well as cropland parcels as per Map M46. <br /> DRMS understands that a vegetation map (M 48B), was prepared in 2021 based on 2017 aerial <br /> imagery and 2021 field mapping. A literature review was conducted establishing the potential <br /> for rare and endangered plant species. Table 2.3-26 records the 115 plant species encountered <br /> during the field survey. A description of the plant communities mapped in the PR11 expansion <br /> area was provided with the revision submitted, the only missing component was the acreage for <br /> the wetland subtype. <br /> DRMS understands that wetland delineation mapping occurred in 2022 and was conducted by a <br /> certified wetlands professional. The results of this survey were not included in the application <br /> submission. <br /> 12. Please submit the wetlands delineation mapping referred to in the revised pages <br /> submitted and include the acreage,for the wetland subtype. <br /> Trapper Response to Comment 12: Enclosed Map M48B is revised to include the mapped jurisdictional wetlands <br /> within the PR-II expansion area.Enclosed permit page 2-122x is revised to include the acreage of the jurisdictional <br /> wetlands within the Drainage Bottoms land cover type. Slight adjustments were made to the acreages of several land <br /> cover types as a result of adjusting the Drainage Bottoms type to incorporate the wetland subtype mapping. <br /> Enclosed page 2-122r is updated to show that the 2022 wetlands mapping has been completed. <br /> Trappers' response adequately addresses the above cited rule. <br /> Rule: 2.04.11 Fish and Wildlife Resources Information <br /> DRMS 28 February 2023 <br /> As per revised page 4-16, a reference was made to Trapper Mine utilizing shrub transplants to <br /> restore nesting and hunting habitat. DRMS understands that Trapper no longer utilizes shrub <br /> transplants. Shrubs are generally used for Range Sites A and B, with Range Site C (big <br /> sagebrush and grass), classified a domestic grazing land where there is no shrub standard as per <br /> permit pages 4-112 through 4-119. <br /> 13. Please update as necessary the language on page 2.04.11 to reflect Trappers current <br /> vegetation reclamation practices regarding shrub transplants for the above referenced <br /> page. <br /> Trapper Response to Comment 13: With the approval of PR-9,the shrub density standard was changed to either <br /> utilize shrub clumps or achieve a higher density standard(going from 400 stems per acre to 550). Trapper still <br /> reserves the right to use either standard,depending on specific circumstances in the field. Trapper acknowledges <br /> that we have recently used the higher density standard approach rather than the shrub clump approach. <br /> Trappers' response adequately addresses the above cited rule. <br /> Rule: 2.04.12 Prime Farmland Investigation <br /> DRMS 28 February 2023 <br /> DRMS understands that portions of the expansion area were cropland areas at one time. DRMS <br /> does not note a determination regarding the presence or absence of Prime Farmland in the <br /> expansion area. Also, Figure 4.5-2 page 4-146 of the permit illustrates cropland parcels. <br /> 6 <br /> Trapper Mine PR I ADQ No 2 <br /> 2023 February <br />
