DRB -15000
Dear Ms. Higgins:
On behalf of Durham County Utilities we are applying for a US Army Corps of
Engineers (USACE) Nationwide Permit 12 and an NC Division of Water
Resources (DWR) Water Quality Certification 3884 for proposed impacts to
jurisdictional waters associated with sanitary sewer improvements in Durham
County. The project area extends from just south of Chin Page Road to Stirrup
I Iron Creek along a tributary to Stirrup Iron Creek in Durham, North Carolina.
The project lies within the Neuse River Basin. The following attachments are
included as part of this permit application:

PROJECT LOCATION/HABITAT: The project area extends from just south
of Chin Page Road to Stirrup Iron Creek along a tributary to Stirrup Iron Creek
in Durham, North Carolina. The 2.70 -acre project area is located within an
existing Durham County Sanitary Sewer Easement.
The entire project area is an existing sanitary sewer easement consisting of
maintained herbaceous vegetation. Within the vicinity of the project area, there
is residential development to the south, and forested areas to the north, as well
as a power line easement that bisects the project area.
JURISDICTIONAL FEATURES: The subject property drains to Stirrup Iron
Creek, which is designated Class C/NSW, and is a tributary to Crabtree Creek
within the Neuse River basin (HUC 03020201). There is one perennial stream
feature (Stream A) that originates north of the project area, and flows southwest
adjacent to the project area before it flows into Stirrup Iron Creek. There are
also three intermittent streams (Streams B, C, and D) that flow across the project
area from southeast to northwest into Stream A. Portions of the buffers of all
four stream features fall within the project area. All four streams are depicted
on the Durham County Soils Survey map, and are therefore subject to the Neuse
Watershed Riparian Buffer Rules (Figure 2). These features are not subject to
the City of Durham Stream Buffer Protection Standards. There are five riparian
wetland areas within the project boundary that total 0.920 acres.
The streams and wetlands were flagged by S&EC in January 2016. The limits
of jurisdictional streams and wetlands have not been confirmed at this time.
PROPOSED IMPACTS: The proposed project known as Durham County
Sanitary Sewer Improvements — Chin Page Road is comprised of a 2.70 -acre
project area currently owned by Durham County Utilities. The proposed project
will consist of increasing the capacity of a portion of the existing sanitary sewer
outfall south of Chin Page Road in order to accommodate future development.

The project was designed to minimize impacts to aquatic resources while
utilizing the remaining project area. All sedimentation and erosion control
measures will be implemented before construction to minimize runoff.
Although efforts have been made to avoid impacts to jurisdictional waters, five
wetlands will be temporarily impacted by the installation of the proposed sanitary
sewer. There are a total of 0.288 acres of riparian wetland impacts associated with
the proposed sanitary sewer improvements. There will be three temporary stream
impacts totaling 65 linear feet. There will also be 0.340 acres of impacts to Zone
1 Neuse Watershed buffers, and 0.574 acres of impacts to Zone 2 Neuse
Watershed buffers. All impacts are temporary and will occur within the existing
maintained sanitary sewer easement. Impacted buffers and wetlands will be
seeded following construction to reestablish vegetative cover.
Typical construction equipment, such as a long-arm track -hoe, front end loader,
and bush hog will be used for the initial clearing.

AVOIDANCE and MINIMIZATION: Impacts to jurisdictional streams and
wetlands have been avoided and minimized to the maximum extent practicable.
There are a total 0.288 acres of un -forested riparian wetland impacts, 65 linear
feet of stream impacts, 0.340 acres of Zone 1 Neuse Riparian buffer impacts,
and 0.574 acres of Zone 2 Neuse Riparian buffer impacts associated with
excavation for proposed sanitary sewer upgrades within the project area. All
impacts are temporary and will occur within the existing maintained sanitary
sewer easement. Once construction is complete, all impacted areas will be
seeded to reestablish vegetative cover.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Impacts to jurisdictional streams and wetlands have been avoided and minimized to the maximum extent practicable.
There are a total 0.288 acres of un -forested riparian wetland impacts, 65 linear feet of stream impacts, 0.340 acres of Zone
1 Neuse Riparian buffer impacts, and 0.574 acres of Zone 2 Neuse Riparian buffer impacts associated with excavation for
proposed sanitary sewer upgrades within the project area. All impacts are temporary and will occur within the existing
maintained sanitary sewer easement. Once construction is complete, all impacted areas will be seeded to reestablish
vegetative cover.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Proper sedimentation and erosion control methods will be utilized during all phases of construction and installation, as
described in the Erosion Control Plan sheets to be reviewed and approved by the NC Division of Land Quality and/or
Durham County Erosion Control. All work will take place during dry conditions and can be facilitated from high, non -
jurisdictional, stable ground adjacent to the shoreline. The contractor shall install silt fence, inlet protection, sediment
traps, diversion ditches, tree protection, and other measures as shown on the erosion control plans, clearing only as
necessary to install these devices. All erosion and sediment control measures will be checked for stability and
operation following every runoff -producing rainfall, but in no case less than once every week. Any needed repairs will
be made immediately to maintain all measures designed. An erosion control inspections report is required and will be
kept by the owner's representative.
All slopes shall be graded no steeper than the angle that can be retained by vegetative cover or other adequate
erosion control devices or structures. No material for construction will be placed in wetlands, streams, or Neuse
Buffers at any time. Excavation will be limited to the area necessary for site preparation; all excavated material will be
placed and retained on high ground above the flood pool elevation. All excavated material will be placed landward of
the normal pool elevation contour on high ground and confined by adequate dikes or other retaining structures to
prevent erosion and sedimentation into adjacent waters, wetlands, or Neuse Buffers.

Re: Nationwide Permit 12/GC 3884
Durham County Sanitary Sewer Improvements — Chin Page Road
Durham, North Carolina
DRB -15000
Dear Mr. Alsmeyer:
On behalf of Durham County Utilities we are applying for a US Army Corps of
Engineers (USACE) Nationwide Permit 12 and an NC Division of Water
Resources (DWR) Water Quality Certification 3884 for proposed impacts to
jurisdictional waters associated with sanitary sewer improvements in Durham
County. The project area extends from just south of Chin Page Road to Stirrup
Iron Creek along a tributary to Stirrup Iron Creek in Durham, North Carolina.
The project lies within the Neuse River Basin. The following attachments are
included as part of this permit application:
• Signed Agent Authorization Form

PROJECT LOCATION/HABITAT: The project area extends from just south
of Chin Page Road to Stirrup Iron Creek along a tributary to Stirrup Iron Creek
in Durham, North Carolina. The 2.70 -acre project area is located within an
existing Durham County Sanitary Sewer Easement.
The entire project area is an existing sanitary sewer easement consisting of
maintained herbaceous vegetation. Within the vicinity of the project area, there
is residential development to the south, and forested areas to the north, as well
as a power line easement that bisects the project area.
JURISDICTIONAL FEATURES: The subject property drains to Stirrup Iron
Creek, which is designated Class C/NSW, and is a tributary to Crabtree Creek
within the Neuse River basin (HUC 03020201). There is one perennial stream
feature (Stream A) that originates north of the project area, and flows southwest
adjacent to the project area before it flows into Stirrup Iron Creek. There are
also three intermittent streams (Streams B, C, and D) that flow across the project
area from southeast to northwest into Stream A. Portions of the buffers of all
four stream features fall within the project area. All four streams are depicted
on the Durham County Soils Survey map, and are therefore subject to the Neuse
Watershed Riparian Buffer Rules (Figure 2). These features are not subject to
the City of Durham Stream Buffer Protection Standards. There are five riparian
wetland areas within the project boundary that total 0.920 acres.
The streams and wetlands were flagged by S&EC in January 2016. The limits
of jurisdictional streams and wetlands have not been confirmed at this time.
PROPOSED IMPACTS: The proposed project known as Durham County
Sanitary Sewer Improvements — Chin Page Road is comprised of a 2.70 -acre
project area currently owned by Durham County Utilities. The proposed project
will consist of increasing the capacity of a portion of the existing sanitary sewer
outfall south of Chin Page Road in order to accommodate future development.

The project was designed to minimize impacts to aquatic resources while
utilizing the remaining project area. All sedimentation and erosion control
measures will be implemented before construction to minimize runoff.
Although efforts have been made to avoid impacts to jurisdictional waters, five
wetlands will be temporarily impacted by the installation of the proposed sanitary
sewer. There are a total of 0.288 acres of riparian wetland impacts associated with
the proposed sanitary sewer improvements. There will be three temporary stream
impacts totaling 65 linear feet. There will also be 0.340 acres of impacts to Zone
1 Neuse Watershed buffers, and 0.574 acres of impacts to Zone 2 Neuse
Watershed buffers. All impacts are temporary and will occur within the existing
maintained sanitary sewer easement. Impacted buffers and wetlands will be
seeded following construction to reestablish vegetative cover.
Typical construction equipment, such as a long-arm track -hoe, front end loader,
and bush hog will be used for the initial clearing.

AVOIDANCE and MINIMIZATION: Impacts to jurisdictional streams and
wetlands have been avoided and minimized to the maximum extent practicable.
There are a total 0.288 acres of un -forested riparian wetland impacts, 65 linear
feet of stream impacts, 0.340 acres of Zone 1 Neuse Riparian buffer impacts,
and 0.574 acres of Zone 2 Neuse Riparian buffer impacts associated with
excavation for proposed sanitary sewer upgrades within the project area. All
impacts are temporary and will occur within the existing maintained sanitary
sewer easement. Once construction is complete, all impacted areas will be
seeded to reestablish vegetative cover.
