(S&ME), working with Woolpert, Inc. (Woolpert) on behalf of the applicant Charlotte Mecklenburg Utilities (CMU), hereby submits this request to modify existing authorizations under Nationwide Permit (NWP) No. 12 and corresponding Water Quality Certification (WQC) 3819. The original authorizations, issued in May 2009, were for approximately 201inear feet (If) of permanent stream impacts and 0.05 acre of wetland impacts, and are set to expire in May 2011. Please note that the design channesproposed herein will not result in additional permanent impacts to Waters of the U.S., and as a result, the impact amounts originally authorized remain the same. Accordingly, this PCN is being submitted to authorize additional temporary impacts to Waters of the U.S. and accommodate project delays and construction scheduling in accordance with general and specific conditions pursuant to the aforementioned NWP No. 12 and WQC 3819. The McKee Creek Interceptor begins near the Mecklenburg County/Cabarrus County line (35.25798° N, 80.64664° W) and extends northeast (paralleling McKee Creek) to its tie- in with the Reedy Creek Interceptor (35.28776° N, 80.62907° W - see Figure 1, attached). The McKee Creek Interceptor project involves installation of approximately 12,800 if of gravity sewer in Cabarrus County, North Carolina. The proposed pipe size is 24 inches in diameter. The proposed utility easement will be 60 feet wide, of which 10 feet will be maintained. The project will provide new sanitary sewer service in the McKee Creek Basin, and is designed to accommodate predicted flows in Cabarrus County through the 2050 design year. The proposed project will convey wastewater to S&ME, INC. / 9751 Southern Pine Boulevard / Charlotte, NC 28273-5560 / p 704.523.4726 f 704.525.3953 / www.smeinc.com Request for NWP No. 12 and WQC 3819 Modification SBME Project No. 1357-03-424A McKee Interceptor Protect January 13, 2011 the Reedy Creek Interceptor (USACE Action ID No. SAW-2008-01353-360), and from there the wastewater will travel through the Lower Rocky River Influent Pump Station before ultimately being conveyed to and treated at the Rocky River Regional Wastewater Treatment Plant in Cabarrus County. Since issuance of the original authorizations in May 2009, design changes have occurred that have increased total linear footage of the proposed sewer line and resulted in a net change in temporary impacts to Waters of the U.S. The increase in total linear footage of the sewer line from 12,8001f to 13,010 if is a result of relocation of a flow meter station from Cabarrus County to Mecklenburg County. Relocation of the flow meter station will occur in an upland area and will not result in permanent impacts different from those originally authorized. Additionally, discovery of an Ecosystem Enhancement Program (EEP) easement, obtained by a landowner during easement acquisition by the Water and Sewer Authority of Cabarrus County (WSACC), and the resulting negotiations with EEP have caused project delays and the associated, unavoidable design changes. Result of the negotiation with EEP increased temporary impacts to two emergent wetlands previously authorized for impact, Wetlands E and F, and reduced the sewer easement crossing at Stream 5 (see attached Plan Sheets, 12, 13 and 15). The net change in impacts is outlined in Table l below.

Was IQCI Although an unavoidable net change in impacts has occurred due to design requirements, the proposed impacts are temporary, and the combined new and original proposed impacts remain well below NWP No. 12 and WQC 3819 thresholds. Wetlands E and F, where temporary impacts will increase, are emergent wetlands. These wetlands will be returned to original grade and contour and restored in accordance with the Restoration Plan (see attached). The decrease in sewer easement width across Stream 5 decreases temporary stream impacts by 10 If. Stream 5 will also be restored to its original dimension, pattern, and profile, and temporarily-cleared areas seeded in accordance with the Restoration Plan. As a result of delayed funding and the aforementioned negotiations with EEP, construction of the proposed project is not anticipated to commence until after January 2011. Construction duration for the approximately 13,010 if gravity sewer is estimated to be one year, well beyond the May 2011 authorization expiration. 2 Request for NWP No. 12 and WQC 3819 Modification SSME Project No. 1357-03-424A McKee Interceptor Project January 13, 2011 Based on our conversations with as you, and by copy of this PCN, it is our understanding that this letter will serve to modify an existing authorization to reflect a net change in temporary impacts , and to update the duration of the permit authorizations to accommodate construction delays.

Explain the purpose of the proposed project: The project will provide new sanitary sewer service in the McKee Creek Basin and is designed to accommodate predicted flows through the 2050 design year. 3e. Describe the overall project in detail, including the type of equipment to be used: The McKee Creek Interceptor project entails installation of approximately 13,010 If of gravity sewer in Cabarrus County. The proposed section of sewer will be 24 inches in diameter and will convey wastewater parallel to McKee Creek from the Cabarrus / Mecklenburg County line to the Reedy Creek Interceptor near the confluence of Reedy and McKee Creeks. Construction will take place in a 60-foot wide cleared construction easement, 10 feet of which will be maintained. Equipment to be used on the job includes trackhoes, dozers, trucks, sidebooms, welding rigs and boring machines. Upon completion of the project, a 10-foot wide corridor over the pipeline will be permanently maintained. The project was originally authorized by the USACE and DWQ in May 2009. Permanent impacts associated with the original deisgn entailed approximately 20 linear feet (If) of stream and 0.05 acre of wetlands. The original authorizations are set to expire in May 2011. Design changes currently proposed will not result in additional permanent impacts to Waters of the U.S., and as a result, the impact amounts originally authorized remain the same. This PCN is being submitted only to authorize additional temporary impacts to Waters of the U.S. and accommodate project delays and construction scheduling . 4. Jurisdictional Determinations 4a.

If yes, explain in detail according to "help file" instructions. USACE Action ID No. 200803346, issued May 21, 2009, and DWQ No. 090463, issued May 22, 2009. These permits were issued for the original pipeline route, which has not yet been constructed. 6. Future Project Plans 6a. Is this a phased project? ® Yes ? No 6b. If yes, explain. The McKee Creek Interceptor is divided into two phases. The downstream phase includes the portion of the McKee Creek Interceptor in Cabarrus County. The Cabarrus County phase of the project was originally scheduled for construction in 2010 in support of the incorporation of several private utility systems into the Charlotte-Mecklenburg Utilities public sewer system. The upstream phase, McKee Creek Outfall, includes the portion of the McKee Creek Interceptor in Mecklenburg County. The City of Charlotte has plans to annex additional areas within the McKee Creek Basin in Mecklenburg County in 2011 or later. Since annexation, additional private systems have been impacted by annexation of new areas and the private utility systems serving these areas are expected to be incorporated into the Charlotte-Mecklenburg utility system. Construction of the McKee Creek Outfall is proposed in summer 2011. Page 4 of 13 PCN Form - November 2008 Version C. Proposed Impacts Inventory 1. Impacts Summary 1a.

Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Various alignments along McKee Creek were evaluated. Environmental Constraints Maps (ECM) were prepared to identify environmental and cultural resources constraints to be considered during the preliminary route-selection process. Constraints identified in each ECM were largely based on a literature review, with some ground-truthing of areas identified as wetlands by National Wetlands Inventory mapping. Each ECM identified significant natural resources, including wetlands, Natural Heritage Areas, and Treasure or Champion Trees, in addition to potential cultural resources. The final alignment, developed by Woolpert in cooperation with CMU, WSACC, and S&ME, was designed to avoid/minimize potential impacts to wetlands, watercourses, steep slopes, cultural resources, riparian buffers, and other identified environmental constraints, to all extents practicable, without compromising engineering requirements. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Appropriate sediment and erosion control methods will be implemented prior to initiation of ground disturbance activities to reduce potential impacts to water quality. Potential sedimentation of streams adjacent to the sewer interceptor during and following the construction phase of the project will be minimized by implementation of a State-approved sediment and erosion control plan. This plan will employ a network of sediment traps, rock dam basins, diversion ditches, and/or silt fencing to control the export of sediment from the construction corridor to adjacent undisturbed areas. Sediment and erosion control devices will be observed for compliance with construction contract documents during and after construction, as well as following major storm events, to identify needed repair, maintenance, or redesign. Cleared wetland areas will be stabilized with a restoration seed mix in accordance with the seed mix specified in the project's Restoration Plan. Stream banks will be stabilized with jute netting and a native seed mix. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a.

S&ME retained The Catena Group (TCG) to conduct surveys for freshwater mussels along the McKee Creek project corridor. Based on these protected species reviews, the USFWS concurred that the proposed McKee Creek Interceptor project will not impact federally protected species known to occur within Cabarrus County. 6. Essential Fish Habitat (Corps Requirement) 6a. Will this project occur in or near an area designated as essential fish habitat? ? Yes ® No 6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat? The project is not located in a coastal or marine area. 7. Historic or Prehistoric Cultural Resources (Corps Requirement) 7a. Will this project occur in or near an area that the state, federal or tribal governments have designated as having historic or cultural preservation ? Yes ® No status (e.g., National Historic Trust designation or properties significant in North Carolina history and archaeology)? 7b. What data sources did you use to determine whether your site would impact historic or archeological resources? Potential for cultural resources within the project corridor was also previously addressed during preparation of the EA for this project. A scoping letter was submitted to SHPO during the EA process requesting their comments on the proposed project. SHPO responded that they are not aware of cultural resources affected by the proposed project and , accordingly, had no comment on the project. Additionally, Coastal Carolina Research conducted an archaeological survey of the project corridor in August of 2003. Their survey report was submitted to SHPO for review who concluded that the project would not affect any cultural resources eigible for listing in the National Register of Historic Places. 8. Flood Zone Designation (Corps Requirement) 8a. Will this project occur in a FEMA-designated 100-year floodplain? ®Yes ? No 8b. If yes, explain how project meets FEMA requirements: Project area will be restored to it original contours with no additional aboveground structures outside from manholes, therefore the proposed project will not impact flood elevations. 8c. What source(s) did you use to make the floodplain determination? North Carolina Floodplain Mapping Program GIS layers. Crystal J Fox . ! January 13, Page 12 of 13 PCN Form - November 2008 Version F.

While a majority of mitigation for the proposed project has been accomplished through avoidance and minimization of impacts, the following plan shall be implemented to restore those stream crossings and wetlands that are temporarily-impacted through an open-cut method to facilitate installation of the new sewer line. Proposed restoration activities will include removal of placed fill material and restoration of wetland areas and stream banks to original pre-disturbance contours. Excavated material shall be returned to the trench to the extent possible, and remaining material relocated and retained on an upland site. Substrate containing roots, rhizomes, seeds, etc., will be kept viable and replaced at the surface of the excavated site. A restoration seed mix will be applied to disturbed areas associated with temporary wetland and stream crossings. This seed mix (Table 1) will be applied with temporary groundcover species to provide short-term stabilization of disturbed soil, and will cover the disturbed wetlands and stream banks from the jurisdictional boundary extending five feet landward.
