TrC <br /> 4.4.2 Wetlands <br /> Based on field observations, no wetlands were identified within the Study Area. <br /> NWI-mapped wetland locations were investigated and determined to lack one of more of the three <br /> criteria necessary that define a wetland. Although hydrophytic vegetation (saltgrass [Distichlis <br /> spicata])was present, hydric soil indicators were absent and hydrologic indicators were marginal <br /> at best. In addition, the NWI-mapped wetland locations occur in uplands adjacent to a remnant <br /> unlined stock pond historically and artificially fed by a well pump powered by solar panels. The <br /> pumped water required to fill the cattle pond is no longer necessary as cattle operations have <br /> ceased in the Study Area. See Figure 4 (Appendix A) and Appendix B for representative <br /> photographs and photo point locations. <br /> 4.4.3 Waterbodies <br /> One 0.38-acre manmade stock pond (S-AJL-1) was delineated along a OHWM consisting of a <br /> defined bank situated above mud cracks. The stock pond contained no water at the time of survey <br /> and contained one inlet structure from a solar powered well pump and no outlet structures. <br /> Vegetation was mostly absent except for intermittent patches of saltgrass and kochia (Bassia <br /> scoparia) along and above the OHWM bench. See Figure 4 (Appendix A) for mapped features. <br /> Representative photos of the stock pond are presented in Appendix B. <br /> The NHD-mapped stream located in the northeast section of the Study Area was further <br /> investigated. OHWM indicators were absent and there was no indication of a water course in the <br /> vicinity of the NHD-mapped feature. See Figure 4 (Appendix A) and Appendix B for <br /> representative photographs and photo point locations. <br /> 5.0 Conclusions and Recommendations <br /> A wetland and waterbody delineation survey was conducted within CSC's proposed Kersey Mine <br /> Study Area on October 16 and 20, 2023. This region of Weld County was determined to be within <br /> its normal precipitation range for the three months leading up to the survey. Based on field <br /> observations, no wetlands and one waterbody were identified within the Study Area. The one <br /> 0.38-acre waterbody (S-AJL-1), a former cattle pond, was not observed to have downstream <br /> connectivity to federally jurisdictional waterbodies. <br /> As none of the features were observed to have downstream connectivity to jurisdictional waters, <br /> the Project is not anticipated to be subject to regulation pursuant to Section 404 of the CWA. The <br /> ultimate authority to determine federal wetland and waterway boundaries and jurisdiction rests <br /> with the USACE Omaha District (Denver Office). Decisions made by the USACE may result in <br /> modifications to the conclusions stated in this report. <br /> Colorado Sand Company LLC—Kersey Mine December 6, 2023 <br /> Wetland and Waterbody Delineation Report 6 <br />
