Division of Water Resources 450 West Hanes Mill Road, Suite 300 Winston-Salem, NC 27105 Attention: Ms. Sue Homewood Reference: Request for Permit Revision Clemmons Area Upgrade - Line 443 Davie County, North Carolina DWQ Project No. 20180087 SAW 2018-00459 S&ME Project No. 7435-17-015 Dear Bryan and Sue: On behalf of our client, Piedmont Natural Gas (PNG), S&ME, Inc. (S&ME) hereby submits this request for a revision to the existing permit authorizations for The Clemmons Area Upgrade – Line 443 Project (SAW-2018-00459 and DWR Project No. 20180087) in Mocksville, North Carolina. The proposed project will involve installation of approximately 7.2 miles of natural gas transmission pipeline. Project information was originally provided in a January 16, 2018 Pre- construction Notification (PCN). Impacts to Waters of the U.S. were originally authorized by the US Army Corps of Engineers (USACE) in accordance with Nationwide Permit (NWP) No. 12 on March 18, 2018, and under Water Quality Certification (WQC) No. 4133 by the NC Division of Water Resources on March 13, 2018. Jurisdictional boundaries within the project area were originally delineated by S&ME in April 2017. In anticipation of the start of project construction, S&ME personnel recently conducted a series of April 2018 return site visits to walk the project corridor and review conditions as they currently exist. It was noted that hydrologic conditions in one area differed from those encountered during the original delineation, resulting in an additional small wetland area in the proposed easement. The jurisdictional boundaries of the newly-identified wetland (WY) were delineated, and are depicted on the attached Figures (8rev and 44a), which are designed for Request for Permit Revision S&ME Project No. 7435-17-015 PNG Clemmons Area Upgrade – Line 443 April 17, 2018 2 inclusion in the set of exhibits provided with the original PCN. In addition, a summary of the revised wetland impacts are included in Table 1. During the site visit, it was also noted Wetland WH is located on a portion of the property that has been logged by the landowner since the time of the original delineation, and that wetland should not have been considered forested. Therefore, Table 1 has also been revised to reflect that all impacts to WH are temporary (0.068 acre), and none are permanent.

Therefore, temporary impacts were revised to 0.088 acre, and permanent impacts revised to 0.00 acre. ** Newly-identified wetland. To minimize impacts to WY, a portion of the proposed temporary workspace that was originally planned at this location was eliminated, avoiding impacts to 0.060 acre of wetlands. We do not anticipate that additional mitigation for conversion impacts to WZ should be required. The amount of mitigation that PNG was required to purchase for impacts specified in the original PCN included 0.066 acre for the portion of WH that would be converted from forested wetlands to herbaceous wetlands. However, this did not reflect that WH had been logged by the landowner since the time of the original delineation, and was no longer Request for Permit Revision S&ME Project No. 7435-17-015 PNG Clemmons Area Upgrade – Line 443 April 17, 2018 3 considered a forested wetland. Therefore, Table 1 has also been revised to reflect this, and the 0.066 acre of mitigation that was originally provided for WH adequately offsets the 0.053 acre of conversion now proposed at WY. Thank you for your consideration of the permit revision request. If you have questions or need additional information, please feel free to contact us at 704.523.4726.
