WITHIN NORTH CAROLINA AND VIRGINIA, RESPECTIVELY. THESE INCLUDE

JOHN H. KERR RESERVOIR, FALLS LAKE, B. EVERETT JORDAN LAKE, W.

KERR SCOTT RESERVOIR, AND PHILPOTT LAKE.

These lakes and reservoirs were constructed and exist primarily for the purposes of hydroelectric power generation, flood storage, and/or water supply. They were constructed and are operated under laws and regulations administered by the U.S. Army Corps of Engineers (USACE).

Activities within these waters are the primary concern of, and should be regulated by their respective District, Wilmington and/or Norfolk, U.S. Army Corps of Engineers. This general permit applies to all waters on or within lands owned or under flowage easement to U.S. Army Corps of Engineers. Activities authorized are:

a. Construction of piers, boat ramps, jetties and breakwater structures and installation of dolphins, pilings and buoys, using commonly acceptable materials such as pressure treated lumber, unsinkable flotation materials, and confined concrete.

b. Maintenance dredging of accumulated sediments near boat basins and canals/channels where excavated material is placed and retained on high ground provided the total amount of material removed does not exceed 5,000 cubic yards.

c. Stabilization of eroding shorelines utilizing appropriate bioengineering techniques, construction and backfill of bulkheads, and the placement of riprap material.

d. Installation of submerged and aerial utility lines provided U.S. Coast Guard requirements for aerial lines are met and pre-project elevation contours are restored.

e. Maintenance of existing water intake and outfall structures provided all State and Federal required authorizations have been obtained. Construction of new water intake and outfall structures are not authorized under this general permit.

f. Dredging of accumulated sediments, when lake drawdown allows, with all excavated materials placed and retained on high ground provided the total amount of material removed does not exceed 5,000 cubic yards.

Anyone wishing to accomplish work under the authority of this general permit must submit: 1) name, address, and telephone number of prospective permittee; 2) lot number, street address, and directions to the project location; 3) location of the proposed project, including a vicinity map; 4) a brief description of the proposed project; 5) a plan view of the proposed project including dimensions, and 6) location, and design, if applicable, of the disposal area for any excavated material. All submitted information must be sent to the Operations Project Manager at the lake or reservoir in which the work is to occur.

b. Prior to the commencement of any work, the permittee must receive written approval from the Operations Project Manager. The Operations Project Manager may deny requests for use of this permit based on non-compliance with the Shoreline Management Plan, Master Plan, Operations Management Plan, or any other applicable policy or regulation. The Operations Project Manager may include any additional conditions and/or restrictions that he or she determines to be appropriate. Failure to comply with the Special and General Conditions contained herein or any conditions and/or restrictions stipulated by the Operations Manager could result in a violation ofFederallaw and appropriate action by the Office of the U.S.

Attorney.

Special Conditions

1. For construction of piers, and boat ramps:

a. To be authorized by this permit, all piers shall be pile-supported and in compliance with each individual reservoir's shoreline management plan. Piles, dolphins, jetties and breakwater structures may be of wood, metal or precast concrete. Breakwater structures will be designed to provide for adequate water circulation landward of the structures.

b. This general permit does not authorize construction across or into any natural or manmade channel or water body in any manner that may adversely affect navigation by the general public.

c. This permit does not authorize placement of any pier segment or structure further waterward than allowed by the applicable Shoreline Management Plan for the reservoir, when such Plan is in existence.

d. Piers and adjoining platforms, decks, and "L" and "T" sections will not cumulatively exceed the maximum allowable size of such structures identified in the reservoir's shoreline management plan. A pier may be constructed in and over wetland areas to allow access. Such piers shall be attached to the upland at a point landward of ordinary high water. All piers that cross wetland vegetation shall be an open-pile design, up to five (5) feet wide and have minimum elevation of at least four ( 4) feet between the decking and the wetland substrate. The required 4-foot elevation must be achieved at or above the ordinary high water mark.

e. Wooden jetties will not extend farther than 100 feet waterward of the NWL elevation contours.

f. Wood must be pressure-treated except in areas of boathouses or boat shelters protected from the weather.

g. If the display of lights and signals on the authorized structure is not otherwise provided for by law, such lights and signals as may be prescribed by the U.S. Coast Guard will be installed and maintained by and at the expense of the permittee.

h. This general permit does not authorize any habitable structure or associated facility for nonwater-related use.

i. Boat ramps will not exceed 20 feet in width. During boat ramp construction and maintenance, no fill or construction material may be placed in wetlands.

j. Excavation associated with boat ramp construction or maintenance is limited to the area necessary for site preparation and all excavated material must be removed to uplands.

k. This general permit does not authorize the installation of fueling facilities on authorized structures.

1. The pouring of concrete for the construction of boat ramps must be accomplished within a temporary cofferdam unless the activity can be performed completely in the dry, such as during lake drawdown periods. The introduction of uncured concrete into surface waters is prohibited. Cofferdams left in place after construction is completed require a Section 10 permit if located in navigable waters of the United States.

2. For construction of bulkheads and backfill and placement of riprap:

a. The project must be necessary to combat an existing erosion problem. No material may be placed in excess of the minimum necessary for erosion protection.

b. Where wetlands are present along a shoreline, all shoreline stabilization activities (bio-engineering techniques, construction and backfill of bulkheads, and the placement of riprap material) must be undertaken landward of the wetlands. This general permit does not authorize the discharged of dredged of fill material within wetlands.

c. Bulkhead and riprap alignments will not extend farther waterward than an average distance of two (2) feet, maximum distance of five (5) feet from the ordinary high water mark and may not extend more than 500 feet along a shoreline.

d. Riprap, if required by the Operations Project Manager, will be placed at the base of all bulkheads and will extend a maximum of three (3) feet waterward on a 2:1 slope. All other fill material will be confined landward of bulkheads.

e. Material placed for shoreline stabilization will not exceed an average of one cubic yard per running foot placed below the plane of the ordinary high water mark. Riprap material must consist of clean rock or masonry materials. The use of metal products, organic materials, petroleum-based materials, or unsightly debris is prohibited.

f. To the maximum extent practicable, discharges must not permanently restrict or impede the passage of normal or expected high flows or cause the relocation of the water.

g. No discharge of dredged or fill material may occur in the proximity of a public water supply intake except where the discharge is for adjacent bank stabilization.

3. For excavation and dredging:

a. Excavation for the removal of accumulated sediment from existing basins, access channels and boats slips must not exceed the lesser of the previously authorized depths or controlling depths for ingress/egress. Under no circumstances can the dredged material exceed

5,000 cubic yards. Construction of dead end canals is not permitted under this regional permit.

Dredging and excavation is prohibited within wetlands or vegetated shallows.

b. To avoid potential impacts to fish spawning areas, excavation activities will not occur during the months ofMarch, April, May, or June of any year.

c. Dredging will be limited to channel ward of the ordinary high water mark. Finished depths will not exceed the depth of the receiving waters channelward ofthe work.

d. All excavated material will be disposed of in approved upland disposal area and confined by adequate dikes or other retaining structures to prevent erosion and sedimentation into adjacent waters or wetlands. The temporary placement or double handling of excavated or fill material waterward of the ordinary high water mark is not authorized.

4. For installation of submerged and aerial power lines and utility lines:

a. The minimum clearance for aerial power lines will be governed by system voltage as shown below:

Nominal System Voltage, Kilovolts

115 and below 750-765

Minimum Clearance (ft) Above Bridge Clearances

Clearances are based on the low point of the line under conditions that produce the maximum sag considering temperature, load, wind, length, span and type of supports. Clearances for communication lines, stream gauging cables, ferry cables and other aerial crossings will be a minimum often (10) feet above clearances for bridges. Installation of utility lines will conform to the conditions ofNationwide Permit No. 12.

b. If an easement to fill or cross utility company, State or Federal property is required, such easement must be obtained prior to commencement of work.

c. If the permitted work is on lands subject to an easement in favor ofthe United States for the maintenance and operation of a Federal lake or reservoir, the permittee will remove such structure and improvements at this own expense in the event that, in the judgement of the U.S.

Army Corps of Engineers acting on behalf of the United States, the lands are needed at any time for any purpose within the scope of the easement. All construction within the easement, either temporary or permanent, must be in compliance with the terms and conditions of the applicable easement estate.
