Subject: Stormwater Permit No. SW7190909 MOD
Bridgeton 115kV Substation
Low Density Stormwater Project
Craven County
The Washington Regional Office received a complete Stormwater Management Permit
Application for the Modification of the Bridgeton 115kV Substation project on February 14, 2020. Staff
review of the plans and specifications has determined that the project, as proposed, will comply with
the Stormwater Regulations set forth in Title 15A NCAC 2H.1000. We are forwarding Permit No.
SW7190909 Modification dated February 27, 2020 for the construction of the subject project.
This permit shall be effective from the date of issuance until rescinded, shall void permit
SW7190909 issued on September 27, 2019 and shall be subject to the conditions and limitations as

special attention to the conditions listed in this permit regarding the Operation and Maintenance of the
SCM(s), recordation of deed restrictions, certification of the SCM's, procedures for changing ownership,
and transferring the permit. Failure to establish an adequate system for operation and maintenance of
the stormwater management system, to record deed restrictions, to certify the SCM's, to transfer the
permit, or to renew the permit, will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150E of the

business hours, for the purpose of inspecting all components of the stormwater
management facility.
The permit issued shall continue in force and effect until revoked or terminated. The

stay any permit condition.

the guidelines established in the North Carolina Erosion and Sediment Control Planning
and Design Manual.

9. Approved plans and specifications for this project are incorporated by reference and are
enforceable parts of the permit.

address changes at least 30 days prior to making such changes.
