Re: Winding Pine Pump Station
Dear Mr. Cashion:
MAY 2 3 2019
Raleigh Regional Office
Hazen and Sawyer is pleased to submit two (2) copies of the Winding Pine Pump Station
application package to request issuance of a Sewer Permit for the pump station and the
associated gravity sewer and force main.
Project Description,
The Winding Pine Pump Station (WPPS) is designed to replace the existing Kit Creek Pump
Station (KCPS) that has been prone to regular flooding due to its proximity to Kit Creek. The
pump station's service area will receive flow from Morrisville, the Research Triangle Park (RTP),
and parts of West Cary and Northeast Chatham County and pump these flows to the West Cary
Pump Station. The WPPS is designed maximize use of the existing infrastructure to the extent
practicable in order to convey flow to the West Cary Pump Station.
Since the WPPS will only replace the existing KCPS and not generate any new development,
no additional flow will be introduced to the system. Additional flow will be requested by others as
the service area is further developed.
Encroachments/Permits
Encroachments and permits in progress include the following:
• Sedimentation and Erosion Control
• Water Extension Permit (Town of Cary)
• Tow of Cary Site Plan Permit
Items Included in Application Package
The following lists all the items included with this application package:
1) Check for $480

External Email - think before you click
Brian and Shuyan,
We are reviewing the subject application and need some additional info.
Please tell us the number of pumps, and size of each, that will be installed in the pump station.
The pump station will have 6 total pumps. The will be four (4) 400 horsepower high flow pumps rated for 2,447 gpm at
a total head of 284 feet and two (2)135 horsepower low flow pumps rated for 1740 gpm at a total head of 160
feet. Due to the head differential, the low flow pumps will only run during low flow conditions and will not contribute to
the firm capacity of the pump station. The pump station's firm capacity is 10.6 mgd with the 3 duty and 1 standby high
flow pumps.
With the large amount of sewer line to be constructed, are there any aerial lines, or other high priority lines with this
project?
There will be no aerial or high priority lines with this project as defined in the 2T rules.
Item IX. 2. notes that separation requirements for wetlands is not complied with. Please explain how separations will be
met for this project.

The pipelines that cross the wetlands are designed in accordance with 15A NCAC 02T .0305(g). In particular, the
pipelines meet the water main standards in 15A NCAC 18C. In addition, the two wetland complexes traversed by the
project corridor consist of large wetland complexes that extend quite a distance north of the project corridor and extend
south of the project corridor to Kit Creek. The project corridor is located to reduce the impacts to jurisdictional wetlands
to the extent feasible by placing the corridor in narrow portions of the large wetland complexes. Alternative routes
along the roadway are not feasible due to the required depth of the gravity sewer.
We'll continue drafting the permit upon submittal of the above info.

from installation of the pipe includes temporary impacts during construction activities and less than 1/10 acre of
permanent impacts from conversion of forested wetlands to non -forested wetlands associated with a mandated,
permanent access corridor. Additionally, no federally protected species or designated critical habitat are reported to be
present in the project site or in the vicinity of the project site.
One of the wetland areas occurs where a stream is noted on the NRCS Soil Survey for Wake County. A stream
determination was performed for the depicted feature by DWR. The feature was not found by DWR to meet the
requirements of an intermittent or perennial stream.
Per Section 404 of the Clean Water Act, impacts to the jurisdictional wetlands present within the pipe corridor are
covered under Nationwide Permit 12 — Utility Line Activities. Per Section 401 of the Clean Water Act, the project falls
under DWR Water Quality General Certification No. 4133. Based on the notification requirements associated with
Nationwide Permit 12, neither submittal of a pre -construction notification nor request for a jurisdictional
determination is required for the Winding Pine Pump Station project. Additionally, the proposed project does not meet
any of the thresholds or circumstances that require written approval for a 401 Water Quality Certification from DWR. It
should be noted that the project was designed to meet or exceed the General Conditions of the Nationwide Permit 12
and the design standards required by DWR and General Certification No. 4133.

Brian and Shuyan,
We are reviewing the subject application and need some additional info.
Please tell us the number of pumps, and size of each, that will be installed in the pump station.
The pump station will have 6 total pumps, The will be four (4) 400 horsepower high flow pumps rated for 2,447 gpm at
a total head of 284 feet and two (2) 135 horsepower low flow pumps rated for 1740 gpm at a total head of 150
feet, Due to the head differential, the low flow pumps will only run during low flow conditions and will not contribute to

the firm capacity of the pump station. The pump station's firm capacity is 10.6 mgd with the 3 duty and 1 standby high
flow pumps.
With the large amount of sewer line to be constructed, are there any aerial lines, or other high priority lines with this
project?
There will be no aerial or high priority lines with this project as defined in the 2T rules.
Item IX. 2. notes that separation requirements for wetlands is not complied with. Please explain how separations will be
met for this project.
The pipelines that cross the wetlands are designed in accordance with 15A NCAC 02T .0305(g). In particular, the
pipelines meet the water main standards in 15A NCAC 18C. In addition, the two wetland complexes traversed by the
project corridor consist of large wetland complexes that extend quite a distance north of the project corridor and extend
south of the project corridor to Kit Creek. The project corridor is located to reduce the impacts to jurisdictional wetlands
to the extent feasible by placing the corridor in narrow portions of the large wetland complexes. Alternative routes
along the roadway are not feasible due to the required depth of the gravity sewer.
We'll continue drafting the permit upon submittal of the above info.
Thx
