Universal Transverse Mercator: 15 Name of nearest waterbody: Name of watershed or Hydrologic Unit Code (HUC): St. Louis, 04010201 Check if map/diagram of review area and/or potential jurisdictional areas is/are available upon request.

REVIEW PERFORMED FOR SITE EVALUATION (CHECK ALL THAT APPLY): Office (Desk) Determination. Date: November 15, 2016 Field Determination. Date(s): September 1, 2016 SECTION II: SUMMARY OF FINDINGS A. RHA SECTION 10 DETERMINATION OF JURISDICTION. There are no navigable waters of the U.S. within Rivers and Harbors Act (RHA) jurisdiction (as defined by 33 CFR part 329) in the review area. B. CWA SECTION 404 DETERMINATION OF JURISDICTION. There are no waters of the U.S. within Clean Water Act (CWA) jurisdiction (as defined by 33 CFR part 328) in the review area. 1. Waters of the U.S.: N/A 2. Non-regulated waters/wetlands (check if applicable): 1 Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: This review area was heavily disturbed by previous mine activities, road building and maintenance activities, and utility maintenance activities. LPP-01, LPP-02, LPP-03, LPP-04, LPP-05, LPP-06, LPP-07, LPP-08, LPP-09, LPP-10, LPP-11, LPP-12, LPP-13, LPP-14, LPP-15, LPP-16, LPP-17, LPP-18, LPP-19, LPP-20, LPP-21, LPP-22, LPP-23, LPP-24, LPP-25, LPP-26, LPP-27, LPP-28, LPP-29, LPP-30, LPP-31, LPP-32, LPP-33, LPP-34, LPP-35, and LPP-38, and the Mariska open-water pit do not have a surface or subsurface connection to a Navigable water of the United States. These aquatic resources were determined to be depressional areas that are located in topographic depressions within the landscape with no outlet. This area was visited on 1 Sept 2016 by Corps regulatory staff; no surface connections were present between these aquatic resources and any other waters during the visit. A desktop determination was completed on 15 Nov 2016; desktop resources such as aerial photography, LiDAR derived elevation models and contours, and stream and wetland, were reviewed and we determined that there are no surface connections between these aquatic resources and other waters. The LPP-01 (0.26 acre), LPP-02 (0.10 acre), LPP-03 (0.30 acre), LPP-04 (0.34 acre), LPP-05 (0.01 acre), LPP-06 (0.05 acre), LPP-07 (0.02 acre), LPP-08 (0.01 acre), LPP-09 (0.13 acre), LPP-10 (0.06 acre), LPP-11 (0.01 acre), LPP-12 (0.08 acre), LPP-13 (0.20 acre), LPP-14 (0.59 acre), LPP-15 (0.56 acre), LPP-16 (3.37 acres), LPP-17 (0.72 acre), LPP-18 (2.38 acres), LPP-19 (0.13 acre), LPP-20 (0.28 acre), LPP-21 (0.04 acre), LPP-22 (0.08 acre), LPP-23 (0.07 acre), LPP-24 (0.24 acre), LPP-25 (0.03 acre), LPP-26 (0.01 acre), LPP-27 (0.10 acre), LPP-28 (0.25 acre), LPP-29 (0.08 acre), LPP-30 (0.06 acre), LPP-31 (0.86 acre), LPP-32 (0.02 acre), LPP-33 (0.01 acre), LPP-34 (0.03 acre), LPP-35 (0.04 acre), and LPP-38 (0.14 acre), and the Mariska open-water pit (approx. 26 acres) do not support a link to interstate or foreign commerce because they are not known to be used by interstate or foreign travelers for recreation or other purposes; do not 1 Supporting documentation is presented in Section III.F.
produce fish or shellfish that could be taken and sold in interstate or foreign commerce; and are not known to be used for industrial purposes by industries in interstate commerce. The aquatic resources were determined to not be jurisdictional under the CWA because the aquatic resources lacked links to interstate commerce sufficient to serve as a basis for jurisdiction. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs: N/A B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): N/A C. SIGNIFICANT NEXUS DETERMINATION: N/A D. DETERMINATIONS OF JURISDICTIONAL FINDINGS. THE SUBJECT WATERS/WETLANDS ARE (CHECK ALL THAT APPLY): N/A E. ISOLATED [INTERSTATE OR INTRA-STATE] WATERS, INCLUDING ISOLATED WETLANDS, THE USE, DEGRADATION OR DESTRUCTION OF WHICH COULD AFFECT INTERSTATE COMMERCE, INCLUDING ANY SUCH WATERS (CHECK ALL THAT APPLY): N/A F. NON-JURISDICTIONAL WATERS, INCLUDING WETLANDS (CHECK ALL THAT APPLY): If potential wetlands were assessed within the review area, these areas did not meet the criteria in the 1987 Corps of Engineers Wetland Delineation Manual and/or appropriate Regional Supplements. Review area included isolated waters with no substantial nexus to interstate (or foreign) commerce. Prior to the Jan 2001 Supreme Court decision in SWANCC, the review area would have been regulated based solely on the Migratory Bird Rule (MBR). Waters do not meet the Significant Nexus standard, where such a finding is required for jurisdiction. Explain: Other (explain, if not covered above): Provide acreage estimates for non-jurisdictional waters in the review area, where the sole potential basis of jurisdiction is the MBR factors (i.e., presence of migratory birds, presence of endangered species, use of water for irrigated agriculture), using best professional judgment (check all that apply): Non-wetland waters (i.e., rivers, streams): linear feet width (ft). Lakes/ponds: acres. Other non-wetland waters: 26 acres.
