The two alignment changes occur on Line 448. Below is a summary of the changes proposed to the Line 448 construction footprint from the footprint authorized under Nationwide Permit 12 (SAW -2018-02342) and 401 Permit (DWR # 18-1737). Piedmont is requesting approval to update the permit SAW -2018-02342 authorizing the change to impact locations for two aquatic resources, 448 Wetland 41 and 448 Stream S17. MINOR ALIGNMENT SHIFT FROM PROJECT MILEPOSTS 21.7 TO 21.8 — FIGURE 1 Purpose and Need The City of Clinton, NC (landowner) requested Piedmont move the pipeline alignment as it enters the proposed receiver facility site at the end of Line 448. Description of Change Requested The pipeline moved approximately 150 feet west from the original permitted location as it exits 448 Wetland 41 PFO (refer to Figure 1). The proposed change in alignment occurs from the point of inflection near milepost 21.7 changing the angle of the pipeline alignment as it exits wetland W41A-448 Wetland 41 PFO. The minor alignment shift reduces the authorized wetland impact by 0.073 acres, of which permanent impacts from the conversion of PFO to PEM for routine right-of-way maintenance will be reduced by 0.048 acres (refer to Table 1 below). Additional Surveys Required No additional wetland/waterbody surveys or archaeology surveys were required as the minor alignment shift occurs within the previously surveyed Project study area.

Description of Change Requested The rerouted section of Line 448, from Project mileposts 9.4 to 9.9, results in changes to one jurisdictional aquatic resource crossing location. No additional or new jurisdictional aquatic resources are impacted by the proposed reroute. The pipeline crossing of stream S17 is proposed to be moved approximately 700 feet southeast from the authorized crossing location (refer to Figure 2). The proposed crossing location of S17 occurs within the previously surveyed Project study area. The change in crossing location of S17 results in a reduction of approximately 41 feet to the authorized impact amount for stream S17 (refer to Table 2). Additional Surveys Required Although the proposed crossing location of S17 occurs within the previously surveyed Project study area, additional wetland/waterbody delineation surveys and archeology Phase 1 surveys were required due to much of the reroute occurring outside the previously surveyed Project study corridor. The wetland/waterbody delineation surveys occurred on June 25, 2019. Wetland/waterbody delineations determined that no additional or new jurisdictional waters occur along the rerouted section. Results from the wetland and waterbody delineation surveys are provided as Attachment A to this memo. Due to the proposed change in crossing location of stream S17, Phase I archaeology surveys were conducted on June 28, 2019 at the proposed crossing location of S17, along the north side of stream S17, and throughout the rerouted survey corridor. Archaeology shovel tests were negative, and surveys determined that no archaeological sites occur within the reroute. Results from the archaeology surveys are provided as Attachment B to this memo.

The changes requested do identify crossing (i.e., impact) configurations and/or locations that are different from the authorized impacts of two aquatic resources, wetland W41A-448 Wetland 41 PFO and stream S17. Piedmont is requesting review and authorization for the proposed changes as identified in Figures 1 and 2. Please let me know if you have any questions or if there is anything else I can do to assist with your review.

Since the time of the original delineation surveys, and after the completion of the Wetland and Waterbody Delineation Report, a reroute was proposed to avoid impacts to one landowner. The Project and rerouted section of Line 448 is located within Sampson County, North Carolina. The rerouted section of Line 448 occurs near Project milepost 9.4 and continues to milepost 9.9. The Project Study Area (PSA) defined for the proposed reroute consisted of a typical 200 -foot -wide survey corridor developed to provide 100 -feet on both sides of the proposed rerouted pipeline. A map showing the location of the proposed rerouted section of Line 448, the PSA, and results of the wetland and waterbody delineation survey is provided as Figure 1, Appendix A. Survey Methods and Results Mott MacDonald conducted wetland and waterbody delineation surveys throughout the rerouted PSA on June 25, 2019. Field methods for the reroute delineation surveys were consistent with protocols identified in the Project's Wetland and Waterbody Delineation Report and with the Corps of Engineers 1987 Wetland Delineation Manual and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region (Version 2.0). Surveys identified presence of one non jurisdictional agricultural ditch (D01) excavated within upland areas and confirmed the location of the previously identified intermittent stream (S17). No wetlands or other special aquatic resources were identified during surveys. Surveys confirmed that the U.S. Fish and Wildlife Service, National Wetlands Inventory mapped wetland polygon which enters the reroutes PSA does not meet wetland criteria and is in fact upland forest consistent with other upland forested areas within the surveyed corridor. No wetland resources were identified within the surveyed corridor. Intermittent Stream Description Intermittent streams are primarily natural drainage systems that typically have continuous surface flow at least seasonally. For jurisdiction purposes, intermittent streams within the PSA were determined to be non - navigable tributaries of Traditional Navigable Waters (TNWs) that are relatively permanent (i.e., tributaries that typically flow seasonally). Intermittent streams are often dry channels for portions of the year or may contain relatively permanent pools without continuous flow between pools throughout portions of the year. Intermittent streams were determined in the field by the presence of an OHWM and either low or no flow at the time of field visit. Stream S17 was previously identified as an intermittent stream and was confirmed as an intermittent stream during this survey. Stream S17 has been straightened, or channelized, and appears to have been excavated during the channelization efforts as it is deeply incised. However, S17 appears to be a straightened former stream that historically occurred near its current location. Therefore, though modified and straightened, Stream S17 was determined in the field as meeting criteria for a jurisdictional intermittent stream. The stream channel was dry on June 25, 2019. Non jurisdictional Ditch Description Ditches are man-made, or man -altered drainage systems that have characteristically straight channels used to collect, transport, or connect surface water flows. In accordance with the Rapanos Guidance, certain ditches or canals that transport relatively permanent (i.e., continuous at least seasonally) flow directly or indirectly into TNWs or between two or more waters of the U.S. (WOUS), including wetlands, are Page 3 considered jurisdictional waters regulated under the Clean Water Act (CWA). Additionally, certain ditches that contribute to a surface hydrologic connection where the ditch replaces or relocates a former WOUS (i.e., stream or wetland), or connects a WOUS to another WOUS, or provides relatively permanent flow to a WOUS are considered jurisdictional waters regulated under the CWA. Ditches, including roadside ditches, that do not meet these requirements and were excavated wholly in and draining only uplands and do not carry a relatively permanent flow of water are considered non jurisdictional features that are not regulated under the CWA. Ditch D01 identified during the June 25, 2019 survey was field determined to be a non jurisdictional agricultural ditch, vegetated and not exhibiting an ordinary high-water mark, excavated in upland areas and only draining upland agricultural fields. The ditch was dry on June 25, 2019. The data collected in the field and results of the delineation surveys are presented on Figure 1 in Appendix A. The Corps of Engineers Wetland Determination Form completed during surveys is provided in Appendix B. Site photographs taken at GPS plot locations are provided in Appendix C. Pipeline Related Impacts to Waterbodies The proposed rerouted Project construction activities will temporarily disturb approximately 78 linear feet of Stream S17. The previously authorized impact to Stream S17, which occurs approximately 700 feet northwest of the proposed reroute crossing, totaled 119 feet. As proposed, the rerouted crossing of Stream S17 will reduce overall authorized impacts by approximately 41 linear feet. Temporary construction impacts to Stream S17 may result in short-term temporal impacts to stream bank vegetation and channel substrate. Open -cut stream crossings will be constructed using a dry -channel method such as dam -and -pump or dam - and -flume to prevent construction activities from contacting flowing water. Following construction and reclamation to preconstruction contours, the stream channel and banks will be allowed to revegetate to preconstruction conditions. Stream banks will not be maintained or mowed for a narrow buffer, minimum of 10 feet on either side of the streams top -of -bank to allow for natural recruitment and to establish and promote stable banks.

(New South) completed an archaeological survey of a proposed reroute on Duke Lines 448/449 in Sampson County, North Carolina (Figure 1). New South conducted an archaeological survey for the primary routes that were documented in a technical report by McMahon and Stephens (2019). On June 6, 2019, the North Carolina Office of State Archaeology (OSA) concurred with the results and recommendations in that report. Since the time of the original survey and after completion of the technical report, a reroute was added to avoid impacts to one landowner. The area of potential effects (APE) for the reroute was a 300 -foot buffer around jurisdictional features. The reroute crosses previously identified Stream 17 in a new location that was outside the boundary of the previous archaeological survey. The new crossing is on the north side of Stream 17 and follows it for a distance of approximately 150 meters. Previous archaeological survey was conducted on the stream's south side (Figure 2). I conducted archaeological survey of the reroute on June 28, 2019. Field methods included shovel testing at 30-m intervals within the APE. A single transect was sufficient to cover the APE and eight shovel tests were excavated (Table 1). All shovel tests were negative. Stratigraphic profiles indicated intact soil deposits for tests 1-6 and 8; shovel test 7 showed evidence of highly mottled soils that have been heavily impacted by agricultural activities. The stream itself is deeply incised and appears to have been channelized in the past.

No archaeological sites were located or identified during that phase of work. Results from the additional survey are consistent with the previous results. No archaeological sites were located or identified within the reroute's APE. Therefore, New South recommends no additional work is necessary at this time.
