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.

Location: The proposed project is located along the left descending bank of the North Canadian River approximately 1.5 miles east of the town of McLoud in Section 11, Township 11 North, Range 2 East, Pottawatomie County, Oklahoma. The project site can be found on the USGS, 1:24,000- scale, McLoud, Oklahoma 7.5-minute Quadrangle at North Latitude 35.43599, and West Longitude 97.06741.

Purpose: The basic purpose of this work is bank stabilization. There are no special aquatic sites on the project. A water dependency determination is not necessary since no special aquatic sites are located within the project site.

The overall project purpose would stabilize approximately 1,250 lf of the left descending bank of the North Canadian River. The bank stabilization proposed by the applicant would prevent further lateral migration of the North Canadian River and prevent the exposure of the existing 12-inch and 16-inch natural gas pipelines.

Description of Work: Approximately 280 lf of the left descending bank of the North Canadian River closest to the 12-inch and 16-inch natural gas pipelines (Enclosure 4-5) would be graded and overlayed with clay earthen fill material to create a 2:1 graded slope. Following the grading of this approximately 280 lf portion of the overall project, 280 lf of 12-inch to 18-inch riprap would then be placed on top of the earthen fill
material that would extend from beyond the top of the highbank to the toe of the bank stabilization system. A system of Longitudinal Peaked Stone Toe Protection (LPSTP) would then be constructed via the placement of approximately 1,250 lf (this total includes the 280 lf of grading and riprap placement previously mentioned, see Enclosure 2-3) of 12 to 18-inch riprap along the toe of the left descending bank of the North Canadian River. The LPSTP would be supported by approximately 24 riprap keys that would be constructed approximately every 54 lf. The construction of the riprap keys would include the excavation of the riverbank to achieve a slope of approximately 2:1 before extending the riprap key from the LPSTP to beyond the top of the highbank (Enclosure 7). Lastly, a system of 24 embedded bendway weirs, each measuring approximately 30 by 7 by 3 ft, would be constructed approximately every 54 lf throughout the 1,250 lf bank stabilization effort.

The proposed work would be accomplished by placing all fill material via a front-end loader and/or a tracked excavator. All materials and equipment would be staged onsite within the 4.12-acre work area that is depicted on Sheet No. C-701 (Enclosure 2).
