Subsequently, Mr. Ian McMillan and I discussed the work. The following additional information is enclosed, in response to your letter and that telephone conversation: 1. A section from the Raleigh East USGS quad map, showing the location of the transmission structure that is threatened by streambank erosion. 2. An aerial photograph showing the structure adjacent to the stream bank. 3. A drawing, showing the approximate footprint of the structure. 4. Photographs, showing the relative location of the structure, and the extent of the streambank erosion. As shown on the enclosed drawing and photographs, all proposed work will be in Zone 1 of the buffer. Work will be limited to restoring only the eroded streambank, filling in the eroded area with soil, and topping that with fabric and a minimal amount of riprap to stabilize the slope and prevent further erosion. There will be no cutting of existing vegetation. As shown on the enclosed drawing, the approximate dimensions of the repair area are 12 feet wide by 15 feet high (stream bank height). This area is somewhat smaller than originally anticipated. Please contact me if there are additional questions. Thank you again for your interest and help in resolving this concern.

' 1650 Mail Service Center Raleigh, NC 27699-1786 Subject: Stabilization of Crabtree Creek Streambank to Protect Existing Overhead Electric Transmission Line Structure Dear Messrs. Matthews and Dorney: During routine inspection of our transmission lines, Progress Energy Carolinas (PEC) found severe streambank erosion adjacent to an existing transmission line structure and its supporting guy wires (collectively referred to as structure). The structure, which is located adjacent to Crabtree Creek in Raleigh, near Wake Medical Center, is shown on the enclosed map and photographs. PEC is submitting the enclosed PCN, seeking approval under NWP 13, "Bank Stabilization". We would note that the erosion appears to be caused primarily by an existing stormwater outlet, which discharges across the transmission line ROW, and drops near vertically into the creek. Because the stormwater discharge cannot be readily addressed, we see no reasonable alternative other than placement of riprap to armor the streambank to protect both the streambank itself as well as the existing structure against further erosion. PEC proposes to reshape the bank to near its original contour with clean soil, and then stabilize the area with erosion control fabric covered with riprap. The naturally steep slope of the creek in this area does not appear suitable for stabilization by vegetative means. Use of the riprap should stabilize the bank, and diffuse/moderate the stormwater flow from the adjacent development. Progress Energy Carolinas, Inc. P O.

VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://li2o.enr.state.nc.us/ncwetlands/strmgide.litm1. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. No further mitigation is proposed Streambank restoration will in fact reduce on-going erosion problem caused by stormwater flow. Page 6 of 9 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form.

All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify V Yes ® No ? Page 7 of 9 If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Zone* Impact Multiplier Required (square feet) Mitigation 1 +1-50 3 (2 for Catawba) See (3) below 2 1.5 Total I I I * Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone 1. 3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0244, or .0260. Project is considered restoration/enhancement in that it is addressing not only Progress Energy's transmission structure but the severe streambank erosion caused by the stormwater outlet. Project will significantly reduce in-stream sedimentation resulting from bank erosion, which in turn is caused by a long-existing stormwater outlet from nearby development. XI. Stormwater (required by DWQ) Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. Site (right-of-way) currently has no impervious surface other than poles (approximately 24" diameter) and city sewer manholes. Placing fabric and riprap on streambank will result in negligible increase in impervious surface relative to overall area. XII. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. N/A XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules? Yes ? No N Is this an after-the-fact permit application? Yes ? No N XIV. Cumulative Impacts (required by DWQ) Page 8 of 9 Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? Yes ? No If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent North Carolina Division of Water Quality policy posted on our website at http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: XV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control). ,3 /1& /aG Appli?Ant/Agent's Signature Date (Agent's signature is valid only if an authorization letter from the applicant is provided.)
