I William L. Pinnix, PE; Dir of Engr certify to the best of my knowledge that the addition of
the volume of wastewater to be permitted in this project has been evaluated along the route to the receiving
wastewater treatment facility and that the flow from this project is not anticipated to cause any capacity
related sanitary sewer overflows or overburden any downstream pump station en route to the receiving
treatment plant under normal circumstances, given the implementation of the planned improvements
identified in the planning assessment where applicable. This analysis has been performed in accordance
with local established policies and procedures using the best available data. This certification applies to
those items listed above in Sections I and I1 plus all attached planning assessment addendums for which I
am the responsible party. Signature of this form certifies that the receiving collection system or treatment

SEWER SYSTEM:
This private gravity system is designed to service a 216-unit 3-bedroom single
family residential duplex subdivision with a total flow of 45,360 GPD. A total of 5,566 LF
of 8-inch sewer line will be needed to complete the system. This new system will
discharge into a proposed pump station located on -site. 1,985 LF of proposed 4" SSFM
will run from the pump station and connect into an existing 8" forcemain on NC 904.
This system will be served by Brunswick County Public Utilities.

Sewer Plans Approval
Dear Mr. Norris:
BEVERLY ADAMS
Engineering Administrator
Our office has reviewed the proposed plans and specifications for the new gravity sewer and pump station
extension for the proposed Townes at Seaside and has determined that this project will meet Brunswick
County's minimum standards and specifications if the project is constructed as designed. Brunswick
County has a sufficient sewer treatment capacity to provide sewer service to this project.
This letter hereby grants authorization for the plan submittal to the North Carolina Department of
Environmental Quality / Division of Water Quality for review and approval. Your signed sewer main
extension permit application and FTSE 10/18 forms are enclosed. Please send a copy of this letter to
the State along with your plans, specifications and permit applications.
Please do not hesitate to contact our office if you have any questions.
