Overview facing north of Aquatic Resource A where it Photo 8.Overview facing south of Aquatic ResourceA where <br /> can be diverted to the Arkansas River (boundary depicted by it can be diverted to the Arkansas River(boundary depicted <br /> blue line). by blue line). <br /> AQUATIC RESOURCE B (7.49 ACRES) <br /> Aquatic Resource B is comprised of a PEM1A wetland habitat situated in the north-central portion of the survey <br /> area. Hydrology within Aquatic Resource B appears to be solely supported by seepage from three separate holding <br /> ponds north of the overall mine permit boundary. Surface water was observed in Aquatic Resource B at the time <br /> of the delineation as stagnant,standing water.As described in Section 4.3,Aquatic Resource B eventually dissipates <br /> within the north central portions of the survey area (See Figure 3) and is completely surrounded by uplands. <br /> The boundary of Aquatic Resource B was delineated based on the presences of hydric soils, dominance of <br /> hydrophytic vegetation combined with indicators of hydrology. <br /> The vegetation community within Aquatic Resource B is dominated by species such as black willow, eastern <br /> cottonwood, broadleaf cattail (Typha lotifolia), willow baccharis (Baccharis salicino), curly dock (Rumex crispus), <br /> and careless weed (Amaranthus palmeri). The dominant species within the wetland area consists of hydrophytic <br /> species (FAC-FACW). <br /> Soils within Aquatic Resource B are generally loamy in texture, meeting criteria for hydric soil indicators F3 <br /> (Depleted Matrix). At the time of the delineation, primary wetland hydrology indicators Al (Surface Water), and <br /> A3 (Saturation) was observed within Aquatic Resource B. Additionally, secondary hydrology indicators included: <br /> D2 (Geomorphic Position). Aquatic Resource B meets the criteria for a wetland based on the presence of <br /> hydrophytic vegetation, hydric soils, and wetland hydrology. <br /> Aquatic Resource B comprises a total of 7.49 acres within the survey area (Appendix A).
