SWG040000—General Permit to Construct a Linear Utility Line and Associated
Incidental Built-Upon Area(SWG04)
Atlantic Coast Pipeline
Raleigh Region
North Carolina
Mr.Patterson:
Dominion Energy Transmission Inc.(DETI)on behalf of Atlantic Coast Pipeline,
LLC is submitting the enclosed SWG04 General Stormwater Management Permit
package for the built-upon areas of the Atlantic Coast Pipeline project within the
Raleigh Region. The work is being completed in association with Atlantic Coast
Pipeline,LLC's October 13,2017 Certificate of Public Convenience and Necessity
from the Federal Energy Regulatory Commission(FERC)to construct and operate
the Atlantic Coast Pipeline(ACP). DETI is seeking a General Permit from the
DWQ.
The proposed ACP is an interstate natural gas transmission pipeline that would
serve multiple public utilities and their growing energy needs in Virginia and North
Carolina. Atlantic Coast Pipeline LLC,a company formed by four major,regionally
based energy companies: Dominion,Duke Energy,Piedmont Natural Gas and
Southern Company Gas,will develop,construct and operate the Atlantic Coast
Pipeline.
The built-upon area in the DWQ Raleigh Region stormwater jurisdiction is
approximately 1.24 acres and approximately 0.1%of the total project area within the
Raleigh Region. This application is directed towards construction activities that will
result in permanent facilities that will be located in areas subject to North Carolina's
post-construction stormwater permitting requirements. DETI has separately
submitted Erosion and Sediment Control Plans for approval,and sought coverage
under North Carolina's NPDES general permit for construction stormwater

discharges associated with the Atlantic Coast Pipeline. The permanent facilities
include one valve site and two permanent access roads. Only existing roads to
receive additional built-upon area and new roads within the State stormwater
program area are included with this application. A site plan showing the location
and proposed erosion and sediment control best management practices are included
with this package. Upon completion of pipeline construction,the valve site and
access roads will remain in place and the right-of-way will be restored to the pre-
construction conditions.
