Tulsa District Regulatory Permits for Public Comment

PURPOSE:  The purpose of these public notices are to inform you of a proposal for work in which you might be interested and to solicit your comments and information to better enable us to make a reasonable decision on factors affecting the public interest.

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 proposed project is located in Section 31, Township 14 North, Range 4 East., approximately 4.5 miles southwest of Chandler, along the Deep Fork of the Canadian River, in Lincoln County, Oklahoma.  

The proposed MB site lies within the Deep Fork Oklahoma Watershed 8-digit (11100303) hydrologic unit code as designated by the U.S. Geological Survey. Excel Mitigation Center proposes that the primary geographic service area for the MB include central Oklahoma for both wetlands and streams.  

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 project goal is to restore stream and wetland functions and values within the mitigation bank area.  The site is approximately 114 acres in size and is primarily undeveloped rural land located in the Cross Timbers ecoregion of Oklahoma, and is in a transitional zone from the Central Great Plains.  Lincoln County has a humid, subtropical climate characterized by relatively high rainfall (average 40 inches per year).  The growing season in Lincoln County spans from March to November, approximately 211 days.  The applicant proposes to restore and enhance approximately 7,457 linear feet (lf) of ephemeral streams, approximately 4,695 lf of intermittent and perennial streams, enhance 22.7 acres of riparian corridors, restore and enhance 68.3 acres of forested wetlands, and enhance and restore 5.7 acres of upland forest buffer habitat, including re-establishing and improving hydraulic connection of the river and its tributaries to the floodplain and watershed, creating stable meandering channels, and replacing low quality and undesirable species with a diversity of native plants with improved wildlife value.  Excel Mitigation Center proposes to restore riparian areas of streams and wetlands with 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.  A mixture of at least 85 percent hard-mast and a maximum of 15 percent soft-mast producing, or light seeded species, will be planted in both the restoration and enhancement areas.  The site would be monitored for a minimum of 5 years or until success criteria is met, whichever is later, to ensure hydrologic and revegetation success, and would be perpetually preserved.
