Project: Sweetbrier Pump Station and Force Main
Project Number:WR#02180318.00
Subject: Fast Track Sewer Extension Application
To whom it may concern,
Attached is an application for a Fast Track Sewer Extension Permit WithersRavenel is submitting on behalf
of the City of Durham, NC.
The Sweetbrier Pump Station and Force Main project is generally located near the intersection of Olive
Branch Road and Martin Creek. See the attached maps in the submittal package for project location.
The project includes the construction of a submersible sewage pump station and 16-inch force main along
with some onsite and offsite gravity sewer that is being permitted through the City of Durham. The pump
station will serve future development within the sewer basin.
The 401 Water Quality Certification and Section 404 verification(USACE Action ID. No SAW-2018-01873)
have been obtained.
A permit is requested for the following:
Pipelines
Force Main 16-inch 3,195 ft PVC
Pump Station
Pump Station Pumping Rate Total Dynamic Head
Woods Creek Road Elementary 1,624-gpm 101-feet
School Sewage Pump Station
The permit will be for zero flow as no flow will be coming online at this time. Flow will be permitted as
development occurs within the basin.
This Fast Track Application Package includes the following items:
• Fast Track Application (Form FTA 06-21)

Good Morning David,
Since the final engineering certification for Southeast Regional Lift Station,WQ0040459,has yet to be submitted to the
Department,there will be a special condition entered into the permit requiring the EC for that project be submitted prior to
operation of the Sweetbrier PS and FM project.

Hi David,
The time schedule for responses is promulgated in our rules.When we receive responses,then they are typically reviewed in the

order received.Since,Elaine has been handling this review from the beginning to switch would take some time to get up to
speed and thus it shouldn't be an issue to wait until her return next week.

Doug,as Elaine is out and I wanted to make sure the State would still look at approving our FTA I am forwarding our email
exchange to you. Elaine had asked some follow up questions. Everything had been addressed to her satisfaction except
the one question about a Final Certification for the Southeast Regional Lift Station,WQ0040459. I have answered that question
below. We were wondering if the State could approve our FTA? I'm concerned because Elaine asked that we provide the
information before May 9 and her automatic reply states that she will be out of the office through 05/10.
Thanks,

Hello Donald and David,
After reviewing the Fast Track Sewer System Extension Application for the Sweetbrier Pump Station and Force Main project,
additional information is required in order to further process the application. Please provide the following information by May 9.
ZQ2A and note that the requested information must be submitted within 30 days of this request,or the applicant will be required
to submit a new application and application fee in accordance with 15A NCAC 02T.0107.
1. Is this an ARPA funded project?If so,please include the DWI assigned ARPA project number in your response.
No.—04/22/24 response provided
2. According to Section VI.8.,this is a zero flow project. Please provide the following information,which can be included in the
narrative.
Pump stations are typically designed to accept flow from the entire sewer basin,which includes flow that won't be
allocated until well into the future. Much of this flow is"anticipated"and not necessarily known at the time of pump
station design and values used for these future flows is based on several factors including the City of Durham land use
plan. For these reasons,flow has traditionally been allocated with the development and not the pump station itself.
Furthermore,the City of Durham is delegated to approve gravity sewer extensions but not pump stations and force mains.
For this reason,the pump station and force main are permitted separately by the State.—04/22/24 response provided
a. Detailed written justification for a dry line extension as to why the infrastructure cannot wait to be built until closer to
when it's actually needed or until closer to when the future flow will be permitted.
Design of a subdivision that constitutes much of the sewer basin is underway. It is anticipated that there will be flow to the
pump station within weeks of completion of construction of the pump station.—04/22/24 response provided
b. Information regarding when the extension/permit mod to incorporate flow is expected to be made,including what
the expected design flow will be so we can verify that it is sized correctly.
Again,pump stations are typically designed to accept flow not from a single development,but from the entire sewer basin,
which includes flow that won't be allocated until well into the future. Much of this flow is"anticipated"and not necessarily
known at the time of pump station design. For this reason,flow has traditionally been allocated with the development and
not the pump station itself. Design of a subdivision that constitutes much of the sewer basin is underway. It is anticipated
that there will be flow to the pump station within weeks of completion of construction of the pump station. The flow to the
pump station will be permitted by the City of Durham. See attached for Sewer Basin Map(Sewer Shed.pdf)and anticipated
flow(Flow.pdf).—04/22/24 response provided,maps added to application
c. Details as to how the permittee will ensure that no one ties onto this line without a permit,as well as how it will be
valved off from the system to prevent any introduction of wastewater.
The City of Durham is delegated to approve sewer connections to the City's wastewater collection system. A plug will be
installed until such time as sewer is permitted and ready to discharge to the pump station.—04/22/24 response provided,
maps added to application
d. A digital copy of the design plans showing the dry line and its relationship to any other sewers,as well as any
valves/plugs per the comment above.
See attached(03 PUMP STATION SITE PLAN.pdf)and(3.0 OVERALL UTILITY PLAN.pdf).—04/22/24 response provided,maps
added to application
3. According to Section VIII.5.of the FTA,the proposed force main(FM)16-inches,however according to Section V.2.,the
downstream sewer connection is 12-inches. Please provide details indicating how the downstream sewer will be able to
handle the increased flow due to the difference in pipe diameter.

The 12"gravity sewer has a minimum"as designed"slope of 1.90%,which has a full discharge capacity of 2,204 gpm,well
above the 1,624 gpm pumped flow.—04/22/24 response provided,flow calculation added to application
4. According to Section IX.S.,401/404 authorization is not needed for this project.However,404 Permit number SAW-2018-
01873 was provided in the narrative. Please provide the 401 DWR No.associated with this project.
a. Additionally,please update Section IX.S.to indicate that 401/404 authorization is needed for this project.
See attached for revised Section IX.S(FTA 4 of 5.pdf). 404 Permit Number is SAW-2018-01873,401 Permit Number is 20201653.—

5. According to the FTSE for North Durham WRF,the Southeast Regional Lift Station,WQ0040459,is located between the
project and the WWTP. A partial Engineer's Certification(EC)was submitted on 03/30/2022,but the Division does not have
the final EC on file. Has this project been completed and certified? If so,please submit the final EC documentation so that
DWR can update these records.
City of Durham will provide a comment.—As of 04/29/24,still need final EC
6. The topographical and aerial maps submitted are not sufficient. According to Section F of the Application Instructions,an
8.5-inch x 11-inch color copy of a USGS Topographic Map and an aerial map should be included with the application. The
maps need to clearly identify the project area,including the closest surface waters,general location of the gravity sewer,
pumpstations,and force mains,and the downstream connection points for the receiving sewer. Please provide the required
maps according to the application requirements.
The maps have been revised,see attached(Aerial.pdf and USGS Quad Map.pdf).—04/22/24 response provided,maps added
