ERC West Farm Pit Expansion Project Site <br /> - Aquatic Resource Delineation Report <br /> Resource E meets the criteria for a wetland based on the presence of hydrophytic vegetation, hydric soils, and <br /> wetland hydrology. Aquatic Resource E is also defined by an OHWM. <br /> Aquatic Resource E comprises a total of 8.95 acres and 11,743.80 linear feet within the survey area (Appendix A). <br /> Refer to Photos 16-19 below for characteristics within Aquatic Resource D. <br /> J <br /> k" <br /> Photo 16.Overview facing east of Aquatic Resource E(boundary Photo 17.

Overview east of Aquatic Resource E (boundary <br /> (boundary depicted by blue line). depicted by blue line). <br /> 4.3 OFF-SITE CONTINUATION OF AQUATIC RESOURCES <br /> Aquatic Resource A and E were observed to have a direct surface connection to the Arkansas River outside of the <br /> survey area (Red Polygon on Figure 3). Aquatic Resource A (Teal Line in western portion of survey area on Figure <br /> 3)can be directed to flow directly into the Arkansas River(Blue Line north of survey area boundary)via an irrigation <br /> control valve. Aquatic Resource A also can be directed via the same irrigation control valve to flow into Aquatic <br /> Resource C (Yellow Line in central portion of the survey area on Figure 3). Aquatic Resource C eventually drains <br /> into a large irrigation retention pond within the survey area and terminates in uplands. Aquatic Resource B (Pink <br /> Polygon north of survey area) is limited to a low depression and terminates in uplands. Aquatic Resource B <br /> hydrology is supported by seepage from three water retention ponds north of the survey area. Aquatic Resource <br /> D (Purple Polygon in the central portion of the survey area on Figure 3) is limited to a man-made irrigation <br /> retention pond and terminates in uplands in the form of berms.These berms surround Aquatic Resource D entirely. <br /> Aquatic Resource E (Green Line on Figure 3) flows east for approximately 2.22 miles from the survey area before <br /> flowing out of the survey area where it continues for 0.8 miles before draining into the Arkansas River(Blue Line <br /> on Figure 3)a TNW. Aquatic Resources B,C,and D appear to terminate in uplands within the survey area and have <br /> no connectivity to waters of the U.S. Refer to Figure 3.Table 2 is an assessment of wetland connectivity. <br /> 11 <br />
