Subject: Application for Section 401 Water Quality Certifications (WQC No. 3374
and 3366) associated with Nationwide Permits No. 12 and 33 for Speight
Branch Interceptor in Wake County, Town of Cary. Application for "No
Practical Alternatives" determination. Town of Cary Project Number SW-
1053
Dear Cyndi:
The purpose of this letter is to provide you with information concerning the Town of Cary's
proposed installation of approximately 3383 linear feet of sewer trunk within the floodplain of
Speight Branch in Cary, North Carolina (see Sheets 1 and 2). Please find attached this summary
letter, a project vicinity map (Sheet 1), overall plan views of the project study area (Sheets 1 and
2), permit drawings (Sheets 3A-3I), typical wetland cross-sections (Sheets WX1 and WX2),
typical stream cross-sections (Sheets SXI and SX2), a completed Pre-Construction Notification
form for Nationwide Permits (NWP) No. 12 and 33, and a Section 401 Water Quality
Certification application fee of $200.00.
Project Description: The Town of Cary proposes to install approximately 3, 383 linear feet of
sewer hunk line (hereafter to referred to as "Speight Branch Interceptor") within the floodplain
of Speight Branch in the Lochmere Subdivision in Cary, North Carolina (see Sheets 1 and 2).
The Speight Branch Interceptor project (hereafter referred to as the "project study area") is
approximately 3380 feet long and 80 feet wide, encompassing 6 acres. Within the project study
area, proposed construction will take place within a 30-foot wide construction easement (Sheets
3A-3I). The project study area occurs predominantly within the floodplain of Speight Branch
with residential development occurring on side slopes and ridges to the south, east, and west of
the property. The project study area is bordered by Cary Parkway to the north. One stream
(Speight Branch) and multiple wetlands occur within the project study area. Impacts to Section
404 jurisdictional areas are anticipated as a result of the proposed project. Impacts expected as a

result of the proposed project total 0.13 acre of temporary impacts to jurisdictional wetlands,
0.08 acre of permanent impact to jurisdictional wetlands, 53 linear feet of temporary impacts to
jurisdictional streams, and 0.18 acre (56 linear feet) of impact to Neuse River Basin buffer.
Impacts to these jurisdictional areas are expected to occur as a result of mechanized clearing,
excavation, and temporary de-watering of Speight Branch for the proposed installation of the
Speight Branch Interceptor; therefore, the Town of Cary proposes to perform these activities
under NWPs No. 12 (Utility Line Activities) and 33 (Temporary Construction, Access, and
Dewatering).
The project study area is characterized predominantly by Piedmont/Mountain Bottomland Forest
and maintained/disturbed land, with elevations within the project study area ranging from
approximately 340 to 360 feet above sea level. The project area is located in the Piedmont
physiographic province with land uses near the project study area consisting of commercial and
residential development, as well as forestland. One stream, Speight Branch, is located within the
project study area. Speight Branch enters the project study area as a perennial stream with
moderate flow over a substrate of silt, sand, gravel, cobble, and boulders. Bank height ranges
from 1 to 5 feet and bank width ranges to 15 feet. The following table lists Site coordinates.

Purpose and Need: The purpose of this project is to provide a sustained sewer trunk line to
Southern Cary for the foreseeable future in a manner that causes the least possible disturbance to
the surrounding community and environment. Sewer lines both upstream and downstream of the
project study area have been sized to account for current and anticipated development within the
existing sewer service basin. However, because of the small size (approximately 12") of the
EcoScience Corporation
Ms. Cyndi Karoly
March 16, 2006
Page 3 of 6
current sewer line within the project study area, a bottleneck is being created causing the sewer
line upstream of the project study area to back up. Construction of the Speight Branch
Interceptor would eliminate this bottleneck. In addition, it may be possible to divert wastewater
flows from other areas to the Speight Branch Interceptor. Another need for the Speight Branch
Inteceptor is to ease the burden of the Lynn's Branch Interceptor which is located in a sensitive
area next to Lochmere Lake and cannot be readily expanded. The proposed Speight Branch
interceptor has been sized to accommodate this planned flow diversion as well as potential
development within the sewer basin. Subsequently, the Town of Cary does not anticipate
needing any further improvements to the Speight Branch interceptor following its construction.
Impacts Proposed Under NWPs No. 12 and 33: Impacts to jurisdictional areas under the Clean
Water Act (CWA) due to the proposed project footprint include 53 linear feet of temporary
impacts to perennial stream, 0.13 acre of temporary impacts to vegetated wetlands, and 0.08 acre
of permanent impacts to vegetated wetlands, and 0.18 acre (56 linear feet) of impact to Neuse
River Basin buffer (Sheets 3A-3I of the permit drawings). These impacts will occur as a result
of 1) excavation of a 6-foot deep trench in which the Town of Cary will lay the proposed sewer
line, 2) mechanized clearing for access, and 3) the temporary de-watering and diverting of
Speight Branch at specific, and limited, points of crossing by the utility line.
Please note in the permit drawings (Sheets 3A-3I) that the proposed alignment overlaps the
existing alignment for the majority of the length of the project. Because the alignments overlap,
permanent impacts to wetlands will only occur where the proposed alignment deviates from the
existing alignment because these are the only areas where a permanent change in wetland
function (i.e. a change in wetland vegetation) will occur.
The Town of Cary proposes to open cut Speight Branch and temporarily pump around eight
stream crossings in order to install the sewer line under the existing streambed. Subsequent to
construction, the Town of Cary will restore the streambed to pre-construction conditions and
stabilize the streambank using rip-rap in areas where the streambank may be vulnerable to
erosion.
In order to minimize impacts to riparian buffers, the Town of Cary has designed their
construction limits so that they overlap the existing sewer line easement to the greatest extent
possible. Minimal impacts to riparian buffer will occur only where the proposed construction
easement deviates from the existing easement (no riparian impacts are considered to occur in
areas where existing uses are present and on-going [Sheets 3A-3I of the permit drawings]). The
EcoScience Corporation

remaining unavoidable impacts of approximately 56 linear feet are considered to be "Allowable"
under the Neuse River Basin buffer rule.
Avoidance, Minimization, and CompensatorMitigation: The Town of Cary has been at all
times committed to incorporating all reasonable and practical design features to avoid and
minimize jurisdictional area impacts. Avoidance measures were taken during the planning
phases, and minimization methods were incorporated as part of the project design. To the
maximum extent practicable, the proposed project has been designed to maintain preconstruction
downstream flow conditions. In addition, the project has been designed so that no permanent
impacts to Section 404 jurisdictional areas occur as a result of the proposed project.
To minimize temporary impacts to Section 404 jurisdictional areas, the Town of Cary proposes
to perform the following activities:
• Access roads to the project study area have been designed so as to avoid impacts
to Section 404 jurisdictional areas.
• The construction corridor will be limited to less than 30 feet in width, well below
the 40-foot threshold imposed by the conditions of NWP No. 12. In addition,
permanent, maintained access corridors will be restricted to the minimum
practicable width and will not exceed 10 feet in width except at manhole covers.
• In order to minimize impacts to riparian buffers, the Town of Cary has designed
their construction limits so that they overlap the existing sewer line easement to
the greatest extent possible. This minimizes impacts to riparian buffers because
no riparian impacts are considered to occur in areas where existing uses are
present and on-going (including maintained utility lines).
• Mechanized land clearing for the construction of the sewer line will be kept to the
minimum necessary (less than 30-foot wide construction zone).
• The appropriate sediment and erosion control practices which equal or exceed
those outlined in the most recent version of the "North Carolina Sediment And
Erosion Control Planning and Design Manual" will be in full compliance with all
specifications governing the proper design, installation, and operation and
maintenance of such Best Management Practices in order to assure compliance
with appropriate water quality standards.
• All sediment and erosion control measures placed in wetlands or waters will be
removed and the original grade restored within two months after the proposed
project is completed.
EcoScience Corporation
Ms. Cyndi Karoly

• Heavy equipment used in wetlands will be placed on mats.
• Filter cloth will be placed underneath any riprap used for bank stabilization. In
addition, the placement of riprap will be restricted to stream bottoms and banks
directly impacted by the placement of the sewer line. Subsequently, the
streambed will be restored to its original grade and elevation.
• Cleared wetland areas will be re-vegetated with low-growing grasses and other
herbaceous species. Fescue grass will not be used.
• The sewer line will be installed with no joints connected within the footprint of
Speight Branch or within two feet of the streambanks.
To mitigate for any unavoidable impacts to Section 404 jurisdictional areas, the Town of Cary
proposes to perform the following activities:
• Temporary impacts to vegetated wetlands will be mitigated for on-Site by
replacing the top 6 to 12 inches of the excavated trench with topsoil from the
trench. In addition, post-construction grade elevations in wetlands will match
pre-construction contours.
• Temporary impacts to streams will be mitigated for by restoring natural flow to
Speight Branch in crossings where the stream has been pumped around. In
addition, the Town of Cary will restore the streambed to pre-construction
conditions.
• Impacts to riparian buffers that are greater than 40 linear feet but less than 150
linear feet are considered "Allowable" under the Neuse River Basin buffer rules
for utility crossings; therefore, mitigation will not be required.
On behalf of the applicant, EcoScience Corporation is hereby requesting N.C. Division of Water
Quality (NCDWQ) General Certifications (GC) 3374 and 3366, in association with NWPs 12
and 33, for the Speight Branch Interceptor project in Cary, North Carolina. In addition to the
GCs, we are seeking to obtain a "No Practical Alternatives" determination from NCDWQ for
unavoidable impacts to Neuse River Basin riparian buffer. EcoScience Corporation has provided
a list of all conditions of the General Certification and nationwide permit to the applicant.

development occurring on side slopes and ridges to the east and west of the property.
Elevations within the project study area range from approximately 340 to 360 feet above sea
level. The project study area is characterized predominantly by Piedmont/Mountain
Bottomland Forest and maintained/disturbed land. The project area is located in the
Piedmont physiographic province with land uses near the project study area consisting of
commercial and residential development, as well as forestland.
10. Describe the overall project in detail, including the type of equipment to be used: The
Town of Cary proposes to install approximately 3, 383 linear feet of sewer trunk line within
the floodplain of Speight Branch in the Lochmere Subdivision in Cary North Carolina
Heavy-duty construction equipment will be used.
11. Explain the purpose of the proposed work: The purpose of this project is to eliminate a
current bottleneck in the sewer system, as well as to provide long-term sewer capacity within
the existing sewer basin. Sewer lines both upstream and downstream of the proposed project
have been sized to account for current and anticipated development within the existing sewer
basin. However, because of the small size (approximately 12") of the current sewer line a
bottleneck is being created in the sewer system causing the sewer line upstream of the project
study area to back up. Construction of the new sewer line would eliminate this bottleneck It
may also be possible to divert wastewater flows from other areas to the Speight Branch
interceptor. One other area that would benefit from the construction of the Speight Branch
interceptor is the Lynn's Branch interceptor, which is located in a sensitive area next to
Lochmere Lake and cannot be readily expanded. The Speight Branch interceptor has been
sized to accommodate this planned flow diversion as well as to accommodate potential
development within the sewer basin. Subsequently, the Town of Cary does not anticipate
needing any further improvements to the Speight Branch interceptor following its
construction. In summary, the purpose and need of the proposed project is to provide a
sustained sewer trunk line to Southern Cary for the foreseeable future in a manner that causes
the least possible disturbance to the surrounding community and environment

permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Impacts to jurisdictional areas under
the Clean Water Act (CWA) due to the proposed project footprint include 53 linear feet of
temporary impacts to perennial stream, 0.13 acre of tgmporary impacts to vegetate
wetlands, 0.08 acre of permanent impacts to vegetated wetlands, and 0.18 acre (56 linear
feet) of impacts to Neuse River Basin riparian buffer (Sheets 3A 3B 3C 3133E 3F 3G
3H, and 31 of the permit drawings). More detailed descriptions of impacts can be found in
the attached cover letter.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The Town of Car is
committed to incorporating all reasonable and practicable design features to avoid and minimize
stream impacts, and to provide full compensatory mitigation of all remaining stream impacts
Avoidance measures were taken during project planning and minimization measures were
incomorated as part of the project design. Detailed descriptions of avoidance and minimization
measures can be found in the attached cover letter.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
htW://h2o.enr.state.nc.us/ncwetlands/strmgide.htiul.
Updated 11/1/2005
Page 10 of 13
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed. Jurisdictional impacts total 53 linear feet of
temporary stream impacts to Speight Branch, 0.13 acre of temporary wetland impacts 0.08
acre of permanent wetland impacts, and 0.18 acre of riparian buffer impacts. Waters of the
United States temporarily affected by filling, flooding, excavation, or drainage are not
included in the calculation of permanent loss to waters of the United States; therefore
permanent impacts expected to occur as a result of the proposed project include 0.08 acre of
impact to vegetated wetlands and 0.18 acre (56 linear feet) of impact to riparian buffer.
Temporary impacts to streams and wetlands will be restored on-site upon project completion
Restoration of temporarily disturbed stream and wetland areas includes re-establishment of
pre-project stream flow and pre-project stream and wetland elevations. Permanent im acp is to
vegetated wetlands will not require mitigation because they total less than 0.10 acre (Personal
Communication with Monte Matthews, February 27, 2006). Impacts to riparian buffers (56
linear feet) are considered to be "Allowable" under the Neuse River Basin Buffer Rules;
therefore, mitigation will not be required. Detailed descriptions of mitigation measures can
be found in the attached cover letter.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.ne.us/=l /index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): N/A
Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A
IX. Environmental Documentation (required by DWQ)
Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes ® No ?
2. If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No
Updated 11/1/2005

If yes, has the document review been finalized by the State Clearinghouse? If so, please
attach a copy of the NEPA or SEPA final approval letter. Yes ? No ?
X.
Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
213 .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ® No ?
2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers.
If buffer mitigation is required calculate the required amount of mitigation by applying the
buffer multipliers.

3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or .0244, or .0260. Impacts to riparian buffers (56 linear feet)
are considered to be "Allowable" under the Neuse River _Basin Buffer Rules; therefore.
mitigation will not be required
Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss stormwater
controls proposed in order to protect surface waters and wetlands downstream from the property. If
percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed
impervious level. The appropriate sediment and erosion control practices will equal or exceed those
outlined in the most recent version of the "North Carolina Sediment and Erosion Control Planning an
Design Manual." This project will be in full compliance with all specifications governing the proper
design, installation, and operation and maintenance of such Best Management Practices in order to assure
compliance with appropriate water quality standards. In addition, all sediment and erosion control
measures placed in wetlands or waters shall be removed and the original grade restored within two
months after the proposed project is completed.

Subject: Application for Section 401 Water Quality Certifications (WQC No. 3374
and 3366) associated with Nationwide Permits No. 12 and 33 for Speight
Branch Interceptor in Wake County, Town of Cary. Application for "No
Practical Alternatives" determination. Town of Cary Project Number SW-
1053
Dear Cyndi:
The purpose of this letter is to provide you with information concerning the Town of Cary's
proposed installation of approximately 3383 linear feet of sewer trunk within the floodplain of
Speight Branch in Cary, North Carolina (see Sheets 1 and 2). Please find attached this summary
letter, a project vicinity map (Sheet 1), overall plan views of the project study area (Sheets 1 and
2), permit drawings (Sheets 3A-3I), typical wetland cross-sections (Sheets WX1 and WX2),
typical stream cross-sections (Sheets SX1 and SX2), a completed Pre-Construction Notification
form for Nationwide Permits (NWP) No. 12 and 33, and a Section 401 Water Quality
Certification application fee of $200.00.
Project Description: The Town of Cary proposes to install approximately 3, 383 linear feet of
sewer trunk line (hereafter to referred to as "Speight Branch Interceptor") within the floodplain
of Speight Branch in the Lochmere Subdivision in Cary, North Carolina (see Sheets 1 and 2).
The Speight Branch Interceptor project (hereafter referred to as the "project study area") is
approximately 3380 feet long and 80 feet wide, encompassing 6 acres. Within the project study
area, proposed construction will take place within a 30-foot wide construction easement (Sheets
3A-3I). The project study area occurs predominantly within the floodplain of Speight Branch
with residential development occurring on side slopes and ridges to the south, east, and west of
the property. The project study area is bordered by Cary Parkway to the north. One stream
(Speight Branch) and multiple wetlands occur within the project study area. Impacts to Section
404 jurisdictional areas are anticipated as a result of the proposed project. Impacts expected as a
EcoScience Corporation
Ms. Cyndi Karoly
March 16, 2006
Page 2 of 6
result of the proposed project total 0.13 acre of temporary impacts to jurisdictional wetlands,
0.08 acre of permanent impact to jurisdictional wetlands, 53 linear feet of temporary impacts to
jurisdictional streams, and 0.18 acre (56 linear feet) of impact to Neuse River Basin buffer.
Impacts to these jurisdictional areas are expected to occur as a result of mechanized clearing,
excavation, and temporary de-watering of Speight Branch for the proposed installation of the
Speight Branch Interceptor; therefore, the Town of Cary proposes to perform these activities
under NWPs No. 12 (Utility Line Activities) and 33 (Temporary Construction, Access, and
Dewatering).
The project study area is characterized predominantly by Piedmont/Mountain Bottomland Forest
and maintained/disturbed land, with elevations within the project study area ranging from
approximately 340 to 360 feet above sea level. The project area is located in the Piedmont
physiographic province with land uses near the project study area consisting of commercial and
residential development, as well as forestland. One stream, Speight Branch, is located within the
project study area. Speight Branch enters the project study area as a perennial stream with
moderate flow over a substrate of silt, sand, gravel, cobble, and boulders. Bank height ranges
from 1 to 5 feet and bank width ranges to 15 feet. The following table lists Site coordinates.

Purpose and Need: The purpose of this project is to provide a sustained sewer trunk line to
Southern Cary for the foreseeable future in a manner that causes the least possible disturbance to
the surrounding community and environment. Sewer lines both upstream and downstream of the
project study area have been sized to account for current and anticipated development within the
existing sewer service basin. However, because of the small size (approximately 12") of the
EcoScience Corporation
Ms. Cyndi Karoly
March 16, 2006
Page 3 of 6
current sewer line within the project study area, a bottleneck is being created causing the sewer
line upstream of the project study area to back up. Construction of the Speight Branch
Interceptor would eliminate this bottleneck. In addition, it may be possible to divert wastewater
flows from other areas to the Speight Branch Interceptor. Another need for the Speight Branch
Inteceptor is to ease the burden of the Lynn's Branch Interceptor which is located in a sensitive
area next to Lochmere Lake and cannot be readily expanded. The proposed Speight Branch
interceptor has been sized to accommodate this planned flow diversion as well as potential
development within the sewer basin. Subsequently, the Town of Cary does not anticipate
needing any further improvements to the Speight Branch interceptor following its construction.
Impacts Proposed Under NWPs No. 12 and 33: Impacts to jurisdictional areas under the Clean
Water Act (CWA) due to the proposed project footprint include 53 linear feet of temporary
impacts to perennial stream, 0.13 acre of temporary impacts to vegetated wetlands, and 0.08 acre
of permanent impacts to vegetated wetlands, and 0.18 acre (56 linear feet) of impact to Neuse
River Basin buffer (Sheets 3A-3I of the permit drawings). These impacts will occur as a result
of 1) excavation of a 6-foot deep trench in which the Town of Cary will lay the proposed sewer
line, 2) mechanized clearing for access, and 3) the temporary de-watering and diverting of
Speight Branch at specific, and limited, points of crossing by the utility line.
Please note in the permit drawings (Sheets 3A-3I) that the proposed alignment overlaps the
existing alignment for the majority of the length of the project. Because the alignments overlap,
permanent impacts to wetlands will only occur where the proposed alignment deviates from the
existing alignment because these are the only areas where a permanent change in wetland
function (i.e. a change in wetland vegetation) will occur.
The Town of Cary proposes to open cut Speight Branch and temporarily pump around eight
stream crossings in order to install the sewer line under the existing streambed. Subsequent to
construction, the Town of Cary will restore the streambed to pre-construction conditions and
stabilize the streambank using rip-rap in areas where the streambank may be vulnerable to
erosion.
In order to minimize impacts to riparian buffers, the Town of Cary has designed their
construction limits so that they overlap the existing sewer line easement to the greatest extent
possible. Minimal impacts to riparian buffer will occur only where the proposed construction
easement deviates from the existing easement (no riparian impacts are considered to occur in
areas where existing uses are present and on-going [Sheets 3A-3I of the permit drawings]). The

remaining unavoidable impacts of approximately 56 linear feet are considered to be "Allowable"
under the Neuse River Basin buffer rule.
Avoidance, Minimization, and Compensatory Mitigation: The Town of Cary has been at all
times committed to incorporating all reasonable and practical design features to avoid and
minimize jurisdictional area impacts. Avoidance measures were taken during the planning
phases, and minimization methods were incorporated as part of the project design. To the
maximum extent practicable, the proposed project has been designed to maintain preconstruction
downstream flow conditions. In addition, the project has been designed so that no permanent
impacts to Section 404 jurisdictional areas occur as a result of the proposed project.
To minimize temporary impacts to Section 404 jurisdictional areas, the Town of Cary proposes
to perform the following activities:
• Access roads to the project study area have been designed so as to avoid impacts
to Section 404 jurisdictional areas.
• The construction corridor will be limited to less than 30 feet in width, well below
the 40-foot threshold imposed by the conditions of NWP No. 12. In addition,
permanent, maintained access corridors will be restricted to the minimum
practicable width and will not exceed 10 feet in width except at manhole covers.
• In order to minimize impacts to riparian buffers, the Town of Cary has designed
their construction limits so that they overlap the existing sewer line easement to
the greatest extent possible. This minimizes impacts to riparian buffers because
no riparian impacts are considered to occur in areas where existing uses are
present and on-going (including maintained utility lines).
• Mechanized land clearing for the construction of the sewer line will be kept to the
minimum necessary (less than 30-foot wide construction zone).
• The appropriate sediment and erosion control practices which equal or exceed
those outlined in the most recent version of the "North Carolina Sediment And
Erosion Control Planning and Design Manual" will be in full compliance with all
specifications governing the proper design, installation, and operation and
maintenance of such Best Management Practices in order to assure compliance
with appropriate water quality standards.
• All sediment and erosion control measures placed in wetlands or waters will be
removed and the original grade restored within two months after the proposed
project is completed.

• Heavy equipment used in wetlands will be placed on mats.
• Filter cloth will be placed underneath any riprap used for bank stabilization. In
addition, the placement of riprap will be restricted to stream bottoms and banks
directly impacted by the placement of the sewer line. Subsequently, the
streambed will be restored to its original grade and elevation.
• Cleared wetland areas will be re-vegetated with low-growing grasses and other
herbaceous species. Fescue grass will not be used.
• The sewer line will be installed with no joints connected within the footprint of
Speight Branch or within two feet of the streambanks.
To mitigate for any unavoidable impacts to Section 404 jurisdictional areas, the Town of Cary
proposes to perform the following activities:
• Temporary impacts to vegetated wetlands will be mitigated for on-Site by
replacing the top 6 to 12 inches of the excavated trench with topsoil from the
trench. In addition, post-construction grade elevations in wetlands will match
pre-construction contours.
• Temporary impacts to streams will be mitigated for by restoring natural flow to
Speight Branch in crossings where the stream has been pumped around. In
addition, the Town of Cary will restore the streambed to pre-construction
conditions.
• Impacts to riparian buffers that are greater than 40 linear feet but less than 150
linear feet are considered "Allowable" under the Neuse River Basin buffer rules
for utility crossings; therefore, mitigation will not be required.
On behalf of the applicant, EcoScience Corporation is hereby requesting N.C. Division of Water
Quality (NCDWQ) General Certifications (GC) 3374 and 3366, in association with NWPs 12
and 33, for the Speight Branch Interceptor project in Cary, North Carolina. In addition to the
GCs, we are seeking to obtain a "No Practical Alternatives" determination from NCDWQ for
unavoidable impacts to Neuse River Basin riparian buffer. EcoScience Corporation has provided
a list of all conditions of the General Certification and nationwide permit to the applicant.

9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The project study area is bordered by residential
development to the south, east, and west, and b Cary Parkway to the north. The project
study area occurs predominantly within the floodplain of Speight Branch with residential
Updated 11/1/2005

development occurring on side slopes and ridges to the east and west of the property.
Elevations within the protect study area range from approximately 340 to 360 feet above sea
level. The project study area is characterized predominantly by Piedmont/Mountain
Bottomland Forest and maintained/disturbed land. The project area is located in the
Piedmont physiographic province with land uses near the project study area consisting of
commercial and residential development, as well as forestland.
10. Describe the overall project in detail, including the type of equipment to be used: The
Town of Cary proposes to install approximately 3, 383 linear feet of sewer trunk line within
the floodplain of Speight Branch in the Lochmere Subdivision in Cary North Carolina
Heavy-duty construction equipment will be used.
11. Explain the purpose of the proposed work: The purpose of this project is to eliminate a
current bottleneck in the sewer system, as well as to provide long-term sewer capacity within
the existing sewer basin. Sewer lines both upstream and downstream of the proposed project
have been sized to account for current and anticipated development within the existing sewer
basin. However, because of the small size (approximately 12") of the current sewer line a
bottleneck is being created in the sewer system causing the sewer line upstream of the project
study area to back up. Construction of the new sewer line would eliminate this bottleneck It
may also be possible to divert wastewater flows from other areas to the Speight Branch
interceptor. One other area that would benefit from the construction of the Speight Branch
interceptor is the Lynn's Branch interceptor, which is located in a sensitive area next to
Lochmere Lake and cannot be readily expanded. The Speight Branch interceptor has been
sized to accommodate this planned flow diversion as well as to accommodate potential
development within the sewer basin. Subsequently, the Town of Cary does not anticipate
needing any further improvements to the Speight Branch interceptor following its
construction. In summary, the purpose and need of the proposed project is to provide a
sustained sewer trunk line to Southern Cary for the foreseeable future in a manner that causes
the least possible disturbance to the surrounding community and environment

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The Town of Cary is
committed to incorporating all reasonable and practicable design features to avoid and minimize
stream impacts, and to provide full compensatory mitigation of all remaining stream impacts
Avoidance measures were taken during project planning, and minimization measures were
incorporated as part of the project design. Detailed descriptions of avoidance and minimization
measures can be found in the attached cover letter.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.ne.us/ncwetlands/strrngide.html.
Updated 11/1/2005
Page 10 of 13
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed. Jurisdictional impacts total 53 linear feet of
temporary stream impacts to Speight Branch, 0.13 acre of temporary wetland impacts 0.08
acre of permanent wetland impacts, and 0.18 acre of riparian buffer impacts. Waters of the
United States temporarily affected by filling, flooding, excavation, or drainage are not
included in the calculation of permanent loss to waters of the United States, therefore
permanent impacts expected to occur as a result of the proposed project include 0.08 acre of
impact to vegetated wetlands and 0.18 acre (56 linear feet of impact to riparian buffer.
Temporary pacts to streams and wetlands will be restored on-site upon project completion.
Restoration of temporarily disturbed stream and wetland areas includes re-establishment of
pre-project stream flow and pre-project stream and wetland elevations. Permanent impacts to
vegetated wetlands will not require mitigation because they total less than 0.10 acre (Personal
Communication with Monte Matthews, February 27, 2006). Impacts to riparian buffers (56
linear feet) are considered to be "Allowable" under the Neuse River Basin Buffer Rules•
therefore, mitigation will not be required. Detailed descriptions of mitigation measures can
be found in the attached cover letter.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.ne.us/=/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
