Dear Ms. Homewood and Mr. Bailey:
This correspondence is in follow-up to your September 27, 2017 Notice of Violation and Recommendation
for Enforcement letter regarding the Piedmont Natural Gas (PNG) project referenced above. The project
is located near the Town of Gibsonville (Guilford County) and the City of Burlington (Alamance County),
North Carolina. The approximate center of the project is located at 36.060619° N, -79.552300° W (Figure
1). The project was authorized under Nationwide Permit (NWP) No. 12 from the U.S. Army Corps of
Engineers (USACE) and the corresponding North Carolina Water Quality Certification from the N.C.
Division of Water Resources (DWR) on November 28, 2016.
Based on a September 22, 2017 site inspection that you conducted, it was determined that a temporary
work bridge pad had been installed within Back Creek (Stream Crossing #5) resulting in unauthorized
temporary impacts. In addition, unauthorized impacts were also observed at three other streams (#4, #6
and #7). Crossings #1-3 were not observed during the site visit. The location of each of the subject
crossing was depicted on Figure 1 in our October 9, 2017 response letter.
S&ME (Joey Lawler) met with representatives of PNG and Distribution Construction, LLC at the project site
on October 4, 2017 in order to review the subject stream crossings and determine appropriate measures
for restoring compliance. Results of our site visit, along with the proposed measures that will be
undertaken by PNG to bring the crossings back into compliance, were identified in our October 9, 2017
response letter. The restoration work was completed by October 20, 2017. PNG then notified S&ME, who
conducted a follow-up site visit on October 25, 2017 to document the completed work. A summary of
observations at the subject stream crossings is provided below. Photographs of the subject crossings
taken during the follow-up site visit are also provided (Appendix I).

Crossing #1 (36.061132°N, -79.564203°W) — Excessive riprap originally observed in the channel
bed was removed to more closely approximate the amount that was present prior to construction.
Crossing #2 (36.061160°N, -79.560723°W) - Excessive riprap originally observed in the channel
bed was removed to more closely approximate the amount that was present prior to construction.
Crossing #3 (36.061257°N, -79.548002°) — This stream and wetland crossing were conducted by
horizontal directional drill with no travel lane or maintenance corridor established. Accordingly,
this crossing was not impacted and remains undisturbed.
Crossing #4 (36.061929°N, -79.543163°W) — A small pipe overtopped with gravel was originally
observed at this crossing. The pipe and gravel were removed and the streambanks restored in
accordance with the project's original restoration plan.
Crossing #5 (36.062343°N, -79.538164°). Riprap was initially observed in the streambed under-
laying an equipment bridge. The riprap and bridge were removed and the stream banks restored
in accordance with the project's original restoration plan.
Crossings #6 and #7 (36.061890°N, -79.533015°W / 36.0613631N, -79.536150° ). The pipes and
riprap originally observed in the stream channels were removed and the streambanks restored in
accordance with the project's original restoration plan.
Based on our observations, we concluded that the restoration activities were completed in accordance
with the project's original Restoration Plan, which was included with our October 9, 2017 response letter.
The project should now be in compliance with the applicable NWP/Water Quality Certification conditions.
Thank you for your assistance in this matter. If you have questions or need additional information, please
feel free to contact us at 704.523.4726.
