RE: Follow -Up Written Submission for Permit DWR #20140957 Discharge of
Sediment within Stream SNRH004 and Associated Wetland WNRH005F
Atlantic Coast Pipeline Spread 8
Dear Ms. Higgins:
This letter is to follow-up on the sediment discharge to waters of the state previously reported on
January 14, 2019, and as required by Individual Water Quality Certification Permit No.
20140957, Incident #201900146. Dominion Energy takes environmental compliance very
seriously and immediately notified the Division of Water Resources, Raleigh Regional Office
upon discovery of this discharge, and took immediate action to remedy this issue. The discharge
information and corrective actions are as follows:
O1/14/2019 — Spread 8 -- Following a 1.50 inch rain event, ACP conducted post storm event
NPDES inspections where an area of erosion and sediment controls adjacent to stream SNRH004
and associated wetland WNRH005F were observed to be undermined. The result was a
discharge and deposition of sediment within these Waters of the United States. Material
deposited within both the resource area was removed and brought back within the approved
upland workspace, timber mat bridge was cleaned on the stream crossing, and erosion controls
were repaired and reinforced. Measures to prevent this from reoccurring include completing a
full and final restoration of the Right -of -Way in this area.
If you have any questions or need additional information, please feel free to contact Ryan Mason
at (804)-346-6234 or via email at Ryan.Mason(d)dominionenergy.com.
