Everhart, PhD ??lQ?LS Wilmington District Manager EEB 2 5 2010 DATE: November 12, 2009 DEW-WATERQUALITY WETLMM AND SMRM01M MOCH SUBJECT: Permit Modification Request CAMA Major permit No. 293 Brunswick Steam Electric Plant Intake Canal, Southport, Brunswick. County Mr. Edward Wills,. Jr, Plant General Manager of the Brunswick Steam Electric Plant (BSEP), has submitted a request to modify. State Permit No. 293. State Permit No. 293 was issued to the Brunswick Steam Electric Plant on August 23; 1982 as a State Dredge and Fill Permit for the construction of a fish diversion structure. The permit has been continuously renewed for nriaintenance purposes. Due to the extension granted by Session Law 2009-406, I believe the current Permit renewal will expire on December 31, 2014. Mr. Wills is requesting that the permit be modified to allow the. installation of approximately 10,000 square feet of riprap to stabilize the interior of the fish diversion structure. Approximately 23,000 cubic feet (or approximately 852 cubic yards) of either class 1 riprap or articulating concrete block and #357 stone would be used. The applicant has submitted a check (ck. # 5188) in the amount of $100.00 for the modification request. Should the work be determined to be consistent with DWQ and USAGE regulations and DMF not have any resource concerns regarding the project, this office has no objection to the permit modification request, if subject to the following conditions: 127 Cardinal Drive Ext, Wilmington, NC 28405 Phone: 910-796-72151 FAX: 910-395-3964 Internet: www wwastalmanagement.net An Equal Opportunity V Affirmative Action Employer NorthCarolina Am(rdIllk 1. No vegetated wetlands/marsh grass will be excavated or filled. 2. The riprap material must be free from loose dirt or any pollutant- It must be of a size sufficient to prevent its movement from the site by wave or current action. 3. The riprap material must consist of clean rock or masonry materials such as but not limited to granite or broken concrete. 4. In order to protect water quality, runoff from construction must not visibly increase the amount of suspended sediments in adjacent waters. 5. This permit does not eliminate the need to obtain any additional state, federal or local permits, approvals or authorizations that may be required. b. All conditions and stipulations of the active permit remain in force under this minor modification unless specifically altered herein. Please submit any comments or concerns regarding the proposed development to Doug Huggett in writing by December 3, 2009.

PEC requests the modification be made to allow for the filling of a scour hole that has developed on the canal side of the Diversion Structure.. During maintenance activities at the Diversion. Structure (authorized by Dredge and`Fill Permit Modification dated February 18, 2008), the scope of filling the hole was determined and will be filled with either articulating eoncrete block grid/or rip rap. This is a vital piece of the project as there is now an unbalanced load on the sheet pilings in the scour area. The fill is needed to stabilize the lateral load on the pile wall and create a stable slope (see enclosed drawings), thug avoiding a blowout and An emergency repair of the structure. The fill will be completely underwater, and will be at a depth of no less than (-) 12 feet mean sea level. The entire fill area is approximately 10,000 square feet (0.23 acres). In order to complete the project, Progress Energy Carolinas, Inc. requests the North Carolina Division. of Coastal Management provide its approval as soon as possible. A narrative summary of the project, detailed drawing, and a location map is provided along with a check for $100.00 permit fee. Please contact Steve Cahoon at (919) 546- 7457, or Marty McGowan at (910) 457-2538, with questions or if additional information is needed. Sincerely Edward J. Wills, Jr. Plant General Manager Brunswick Steam Electric Plant Enclosures: Proect narrative, detailed drawings, map and check Progress Energy Carolina, Inc. Brunswick Nuclear Plant RECEIVED Po Box 10429 DCM WILMINGTON, NC Southport, N NC 28461 or]- 0 ,1 2009 Diversion Structure Maintenance Scour Protection Background: A deep hole has developed inside the Diversion Screen caused by scouring of the silt material that was initially at elevation -20' MSL and has scoured to -30' MSL. Scouring has occurred on the channel side of the Diversion Structure that varies from 2 feet to 12 feet deep between support bents 4 and 13. Weak silt material extends to elevation -36' MSL to -39' MSL. The loss of material behind the Diversion Structure has caused an unbalanced load on the cantilevered sheet pile under the seat beam causing the sheet pile to go against the piles of the Diversion Structure support bents and exert a lateral load on the bents. If the slope behind the Diversion Structure were to continue to scour, it would cause an overload to the existing structural piles and bents, possibly causing failure of the structure. Scope Description: A maintenance activity is to be performed to stabilize the lateral load on the cantilevered sheet pile wall under the Diversion Structure seat beam by installing scour protection to minimize the loss of material behind the Diversion Structure and create a stable slope. The fill will be completely underwater. The overall area of the scour protection will not exceed 10,000 ft2 (0.23 acres). See Figure 1 for a plan view of the scour area. Rip rap or a combination of rip rap and articulating concrete block will be used to establish the stable slope. Approximately 23,000 cubic feet of class.1 and #357 stone will be used to fill in the scour hole. See Figure 2 for a typical cross section of the Diversion Structure and scour repair.
