SECTION 10: The U.S. Army Corps of Engineers is directed by Congress through Section 10 of the Rivers and Harbors Act of 1899 (33 USC 403) to regulate all work or structures in or affecting the course, condition, or capacity of navigable waters of the United States.  The intent of this law is to protect the navigable capacity of waters important to interstate commerce.

SECTION 404: The U.S. Army Corps of Engineers is directed by Congress through Section 404 of the Clean Water Act (33 USC 1344) to regulate the discharges of dredged and fill material into all waters of the United States.  These waters include lakes, rivers, streams, mudflats, sandflats, sloughs, wet meadows, natural ponds, and wetlands adjacent to other waters.  The intent of the law is to protect these waters from the indiscriminate discharge of material capable of causing pollution and to restore and maintain their chemical, physical, and biological integrity.

The primary purpose of this MB is to mitigate for unavoidable impacts to streams and wetlands authorized under Section 404 of the Clean Water Act. The HSMB goal is to restore stream and wetland functions and values within the mitigation bank areas. The proposed MB consists of two sites totaling approximately 168.4 acres in size and is primarily undeveloped rural land located in the Central Irregular Plains Ecoregion of Oklahoma. McIntosh County has a humid, subtropical climate characterized by relatively high rainfall (average 45 inches per year). The growing season in McIntosh County spans from March to November, approximately 216 days. In Site 1 the applicant proposes to enhance approximately 4,472 linear feet (lf) of ephemeral streams, approximately 9,017 lf of intermittent, restore approximately 14.6 acres of riparian corridors, enhance 19.0 acres of emergent wetlands, enhance 4.6 acres of scrub shrub wetlands, and enhance and/or restore 40.7 acres of upland prairie buffer habitat, including creating stable meandering channels, and replacing low quality and undesirable species with a diversity of native plants with improved wildlife value. In Site 2 the applicant proposes to enhance approximately 3,711 lf of ephemeral streams, approximately 1,637 lf of intermittent, approximately 3,117 lf of perennial streams, restore 6.1 acres of riparian corridors, restore and/or enhance 60.8 acres of forested wetlands, and enhance and/or restore 17.8 acres of upland prairie and forest buffer habitat, including creating stable meandering channels, and replacing low quality and undesirable species with a diversity of native plants with improved wildlife value. In the restoration and enhancement areas on both sites, Green Country Mitigation, L.L.C. proposes to plant the appropriate species mixture of bottomland hardwoods during the standard planting season (December to March). Seedlings, within restoration areas, will be planted on 12- by 12-foot spacings, for a standard density of at least 302 seedlings per acre. Seedlings, within enhancement areas, will be planted on 14- by 14-foot spacing, for a standard density of at least 225 seedlings per acre. The proposed MB site lies within the Dirty-Greenleaf Watershed 8-digit (11110102) hydrologic unit code as designated by the U.S. Geological Survey. Green Country Wetland Mitigation, L.L.C. proposes that the primary geographic service area for the MB include eastern Oklahoma for both wetlands and streams. The location and general plan for the proposed work are shown on the enclosed sheets, 1 through 3.
