Fast Track Sewer System Extension Modification
Dear Mr. Hunkele:

Wii Regional Ofl e
On behalf of Brunswick County, we respectfully request your review of the following documents
for a modification to the subject project's existing wastewater collection system permit:
• 1 Original and 1 Copy of the Fast Track Sewer System Extension Application
• 1 $480.00 Application Fee Check
• 1 Copy of a Memo Regarding Design Calculations
• 1 Copy of a Site Location Map
• 1 Copy of a Street Level Map
The modification is being requested due to a change in the material and diameter for a portion
of the force main covered under permit no. WQ0039705. 130 linear feet of force main, originally
permitted to be 3" DR 9 HDPE, was installed as 2" SDR 21 PVC due to a construction change
to the method of pipe installation.
Thank you for your attention to this matter. Please do not hesitate to reach out to me should you
need any additional information.
Sincerely,
MCGILL ASSOCIATES, P.A.

TO: Mr. Dean Hunkele, North Carolina Department of Environmental Quality
FROM: Zachary Roman, Project Engineer
DATE: October 14, 2021
RE: Permit No. WQ0039705 As -Built Calculations
Mr. Hunkele,
As indicated on the subject project's as -built drawing, sealed on July 14, 2021, the material and
diameter of a portion of the public force main for the project were changed from the permitted
values. Specifically, 130 linear feet of DR 9 HDPE force main was changed to 130 linear feet of
SDR 21 PVC force main. The as -built conditions for the public portion of the project's force main
are as follows: 503 linear feet of SDR 21 PVC. This change occurred due to a field adjustment
of the installation method for the proposed 130 liner feet of DR 9 HDPE force main (direction
drill to open trench).
The subject project's design calculations, originally sealed on August 31, 2017, and revised on
October 11, 2017, contained a system head calculation for the entire run of force main
(including both the public and private portions). The pipe length value used in the calculation
was 800 linear feet while the actual length shown on the design plans and installed was 653
linear feet. The value used in the calculation was about 22% greater than the actual amount of
force main installed. Therefore, the total dynamic head calculated for the system includes a
factor of safety due to the pipe length value. The change in force main material and diameter
made in the subject project's construction phase would be captured by the originally included
factor of safety; the original design calculations remain valid.
Please review the system head calculation included with this memorandum. Do not hesitate to
reach out to me if there are any questions.
