RE: Haw River Interceptor Project — Burlington, North Carolina
Request for Additional Information and Response to Comments
On behalf of the City of Burlington, Kimley -Horn is submitting the enclosed additional information for
the above referenced project per the US Army Corps of Engineers (USACE) Incomplete Application
notification dated May 12, 2014 and the NC Division of Water Resources (DWR) additional
information request also dated May 12, 2014. This response to comments also addresses
discussions held on site in Burlington during the regulatory field review held on site on June 10, 2014.
In addition to the items discussed below, the City of Burlington also proposes to amend the permit
package to include the construction of an at -grade 12' wide maintenance path through the low -lying
wetland areas near the water treatment plant. The path will be constructed by placing 6 " -12" riprap,
underlain with a geotextile fabric, within the proposed sewer maintenance corridor. The larger rock
will not create concentrated flow paths within the buffer.
As observed during the field review, any maintenance access through the current alignment requires
crossing the two wetland features in the southern reach of the project corridor. Due to access
limitations resulting from the location of the 42" sewer pipe within the maintenance corridor, the size
of the sewer pipe, and the steep topography west of the maintenance corridor, heavy equipment has
no choice but to traverse the wetlands. Equipment passage has resulted in severe rutting and soil
disturbance along the existing sewer maintenance corridor, which increases the potential for
sedimentation input to downstream waters, and destabilizes the wetland system. Additionally, without
the proposed maintenance path, in the event of a failure or emergency situation, the City may need to
bring in outside fill material or rip rap to provide adequate access through the wetland in potentially
adverse conditions to facilitate any emergency repairs or mitigation measures.
The maintenance path will minimize the disturbance to the wetlands resulting from construction
activities while also providing a mechanism to restore the wetland to pre- construction contours and
remove any rutting or temporary impacts that may result from construction or remaining from past

Kimley ))) Ho1 n Page 2
maintenance activities. The path will provide a stable corridor for regular maintenance activities while
also allowing improved access through the wetland areas in the event of an emergency action or
failure condition, while minimizing long term disturbance to the adjacent wetland areas within the
corridor. The path will also direct maintenance equipment and vehicles away from traveling over the
sewer pipe which is shallow in depth through the wetlands due to bedrock.
Wetland impacts resulting from the 12' wide path will be mitigated at a 2:1 ratio by payment into the
NC Ecosystem Enhancement Program's (EEP) In -lieu fee (ILF) payment program. Overall, the
proposed project will be mitigating 0.4248 acres of permanent wetland impacts (0.2999 acre at 2:1
mitigation ratio and 0.1249 acre at 1:1 mitigation ratio) with a total payment to EEP for 0.75 acres of
riparian wetland credits. The temporary impact areas will be returned to pre- construction contours
after the project is completed, and in doing so the project will serve to improve these historically
disturbed wetland areas through re- grading and removal of rutting and soil disturbances with the
uniform replacement of wetland topsoil.
Below is an outline of the USACE and DWR comments with a brief narrative addressing each item.
The USACE comments with Kimley -Horn response and explanation are as follows:
1) Your PCN included impacts to wetlands, streams, and open waters, however these
jurisdictional boundaries have not been verified by the USACE. Please schedule a time for
an on -site verification with the USACE.
a. Jurisdictional boundaries were reviewed on -site on June 10, 2014. Stream S1 and
S3 were confirmed, while stream S2 and the southern branch of S4 were determined
to be non - jurisdictional. The northern branch of S4 shown on the original permit
application documents was confirmed to be jurisdictional. The boundary of wetland 1
was confirmed, but the boundaries of wetlands 2 and 3 were modified such that they
are now combined into wetland 2 on the revised figures and plan sheets, now
covering a larger area within the project corridor.
2) According to the plans, rip rap is proposed for Impacts 1 and 4; however this is not mentioned
in the PCN. Please include these impacts as permanent in the PCN (although they would not
be considered a loss of Waters). Also, please explain why rip rap is not proposed for Impacts
2, 3, and 5.
a. All placement of riprap in jurisdictional features as determined by the June 10, 2014
field review have been considered as permanent fill and the PCN has been updated
accordingly. Rip rap has been proposed for impacts 1, 2, 4, and 5; however impact 3
will result from the replacement of an existing culvert beneath the 42" sewer line.
Any riprap placed at impact 3 will be located behind the concrete head walls that will
be constructed for the new culverts.
3) According to the plans, the utility lines are buried for Impacts 4 and 5; however, they are not
buried for Impacts 1 -3. Please explain how Impact 1 -3 will avoid impeding flow, so as to
comply with Nationwide Permit Condition #2. Please note that, based on the plans, Impact 3
appears to have the effect of permanent fill.

Kimley » >Horn
Page 3
a. Impacts 1 -2 are both aerial crossings, and as discussed at the regulatory field review
on June 10, 2014, these crossings comply with Nationwide Permit Condition #2 by
allowing the baseflow of the channel to pass unobstructed beneath the aerial
crossings. Impact 3 proposes to replace the existing 36" culvert currently carrying
stream S3 beneath the 42" sewer line with two 36" culverts. The proposed activity
will not have the effect of permanent fill within the stream channel and will serve to
improve and better manage the flow of stream S3 through the sewer line corridor.
4) Per Regional Condition #4.1.8 please provide a plan to restore and re- vegetate wetland
areas cleared for construction. Note that Fescue grass shall not be used.
a. Re- vegetation details from the proposed construction plans have been included with
this updated submittal. Wetland re- vegetation specifications have been included that
utilize favorable and native wetland vegetation species and does not utilize fescue
grass.
5) Please confirm that, in wetlands, the top 6 to 12 inches of the trench will be backfilled with
topsoil from the trench, as required in the Nationwide Permit 12 description.
a. Per the requirements of Nationwide Permit 12, areas along the proposed construction
corridor within jurisdictional wetlands require that the top 6 to 12 inches of the trench
utilize the original wetland topsoil. The proposed construction plans have been
updated to outline this requirement. Due to grade restrictions, there may be areas
along the alignment where the pipe is within 6" of the ground surface. In these areas,
as much of the original wetland topsoil as possible will be utilized above the pipe
without mounding soil above the pipe.
The DWR comments with Kimley -Horn response and explanation are as follows:
1) A complete review of the project cannot be conducted until the US Army Corps of Engineers
has verified all stream and wetland locations and the Division of Water Resources has
verified all stream determinations with regards to the Jordan Buffer Rules. A site visit has
been scheduled for June 10, 2014.
a. Jurisdictional boundaries and buffer determinations were reviewed on -site on June
10, 2014. DWR confirmed that streams S1, S3, and the northern branch of stream
S4 are subject to Jordan Buffer Rules.
2) Please provide the Division a copy of your response to May 12, 2014 Incomplete Application
notice from the U.S. Army Corps of Engineers requesting additional information.
a. Responses to both the USACE and DWR have been included as part of this
submittal package.
3) Per Condition 10 GC 3884, "the edge of the construction corridor shall not be installed
parallel to and closer than 10 feet to top of bank. If installation of a line cannot meet this
condition you may request a permit that exempts the Permittee in areas where it is clearly
shown and justified. " It is unclear at the scale provided whether some areas of construction
(including installation of temporary sediment and erosion control measures) will be within 10
feet to the top of bank.
a. As discussed during the regulatory field review on June 10, 2014, the only area
within the proposed project corridor that this situation is present is along the existing

Kimley » >Horn
Page 4
15" sewer line adjacent to stream S1. Due to the presence of bedrock and steep
landscape gradients, the construction corridor will need to be located close to the
right top of bank of S1. Based on the discussion held in the field, the proposed
construction plans have been revised to specify that tree protection fence be placed
no closer than 4 feet from the top of bank. Additionally, the plans require that only
hand pruning of trees is allowed in this area to provide clearance for construction
equipment operation while replacing the sewer line. The bank stability will not be
compromised by the construction, as the sewer line to be replaced is small and
located close to the surface through this area. The City of Burlington and the project
engineer understand that a pre- construction meeting will likely be required by DWR
prior to initiating construction in this area. The purpose of the pre- construction
meeting will be to confirm the setback requirement and constructability of the project
in this location subject to DWR's requirements. For the reasons stated previously,
the City of Burlington formally requests an exemption to condition 10 GC 3884 for this
project.
4) Please clarify why buffer impacts are necessary for a temporary construction easement at
Buffer Impact Area B3.
a. Buffer impacts are necessary for a temporary construction easement at Buffer Impact
Area B3 for material and equipment staging and storage. Due to the steep
topography adjacent to the project corridor, access limitations due to the size and
type of sewer line in the project area, and the presence of multiple stream channels
along the alignment, construction equipment access and available material storage
areas in the corridor are limited. Buffer Impact Area B3 offers good material storage
and equipment staging due to its location along the alignment and minimal clearing
required to utilize the location.
5) It appears that buffer impacts at Impact Area B4 would be considered a utility perpendicular
crossing of a stream. Please clarify why mitigation is being proposed in this location.
a. Buffer Impact Area B4 is a utility perpendicular crossing of a stream impacting less
than 40 linear feet of buffer with a maintained access corridor greater than 10 feet.
Per Jordan Lake Water Supply Watershed Riparian Buffer Rules, this activity is
allowable, and mitigation is not required. The PCN has been updated to reflect this,
and the impact footprint has been updated to reflect the changes discussed at the
regulatory field review on June 10, 2014.
6) The Jordan Buffer Rules allow for temporary buffer disturbances for stream crossings if the
construction corridor is less than 40 linear feet and the permanent maintenance corridor will
be less than 10 feet wide. Please clarify whether the City intends to maintain their corridor at
stream crossings at greater than 10 feet wide.
a. The City of Burlington does intend to maintain stream crossings through the corridor
at 30 -40' as possible by grade and topographic contours. The 30 -40' maintenance
corridor is necessary due to the size of the pipe coupled with the small amount of
cover above the pipe. Throughout much of the corridor, the alignment cannot be
safely crossed with construction or maintenance equipment.

Project Description
3a.
Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The site is currently a maintained sewer utility corridor along a mostly forested tract adjacent to the Haw River. Land use
near the site is mostly residential, with historic industrial activities (quarry, land fill) in the vicinity of the project.
3b.
List the total estimated acreage of all existing wetlands on the property:
0.96 acres
3c.
List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
312 LF
3d.
Explain the purpose of the proposed project:
The project will replace an aging and failure -prone sewer line with a new sewer line that will serve the City of Burlington
for many years into the future, and will also protect downstream water quality by preventing sewer overflows and
discharges into the Haw River. The project will also provide safe and non - destructive access through the low -lying
wetlands along the corridor by constructing a 12' wide at -grade rock maintenance path. The maintenance path will
provide long -term water quality improvement to downstream waters by preventing soil disturbance and floodplain erosion
due to equipment access along the sewer alignment.
3e.
Describe the overall project in detail, including the type of equipment to be used:
The project will replace existing 15" and 42" gravity sewer lines with a 16" and 42" gravity sewer lines (respectively)
mostly within the boundary of the existing utility easement. The project will stay within the existing maintained utility
corridor where possible, though site constraints require some widening of the maintenance corridor. The 12'
maintenance path will be constructed at existing grade by placing rip rap. Backhoes, excavators, dump trucks, bulldozers,
cranes, and other utility construction equipment will be utilized by the proposed project.

PCN Form — Version 1.3 December 10, 2008 Version

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The project will be constructed within the existing maintained utility easement where feasible. Existing access roads will be
used that will not need improvements to be utilized by the construction equipment. A maintenance path will be constructed to
a maximum width of 12 feet to provide improved access through wet areas as needed to prevent future fill for emergency
response during excessively wet conditions. In addition, the maintenance path provides access for heavy equipment that
does not traffic on top of the sewer line through the wetland areas which is relatively shallow due to bedrock.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
All construction activities, staging areas, and material storage will be kept within the existing maintained utility easement and
in uplands where feasible. Existing access corridors will be used by all equipment throughout the project. Erosion and
sediment control measures will be utilized throughout the construction process to protect surface water resources in the
project vicinity. All disturbed areas will be returned to pre- construction contours once construction is complete.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for
® Yes ❑ No
impacts to Waters of the U.S. or Waters of the State?
2b. If yes, mitigation is required by (check all that apply):
® DWQ ® Corps
❑ Mitigation bank
2c. If yes, which mitigation option will be used for this

4e. Riparian wetland mitigation requested:
0.75 acres (.252 acres already secured and paid for — see
attached documentation)
4f. Non - riparian wetland mitigation requested:
n/a acres
4g. Coastal (tidal) wetland mitigation requested:
n/a acres
4h. Comments: Payment was submitted with the original permit application in 2009, and was accepted by NCEEP and is still
on the books with NCEEP. Since the project was never constructed, the mitigation credit has never been redeemed and will
satisfy the mitigation requirements for this application. Receipt of payment provided by NCEEP is attached. Since the 2009
permit application, the project scope has changed and buffer and wetland impacts requiring mitigation will result. A new
request has been sent to NCEEP and the letter of acceptance from NCEEP for buffer and wetland mitigation credits has been
attached.

permittee responsible riparian buffer restoration, payment into an approved in -lieu fee fund).
Buffer mitigation for unavoidable impacts to existing forested areas within Zone 1 of the Haw River has been requested
from NCEEP. The letter of acceptance has been attached for up to 8,250 square feet of riparian buffer mitigation from
NCEEP. Only the final required amount of 6,791 will be invoiced
6h. Comments: Per NCDWQ Clarification Memo 2011 -001 (dated February 3, 2011), impacts outside of the existing
maintenance corridor due to replacement of existing non - electric utility lines within Zone 1 will require mitigation, but
impacts to Zone 2 are considered allowable and do not require mitigation.

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or
❑ Yes ® No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act
❑ Yes M No
impacts?
E] Raleigh
5c. If yes, indicate the USFWS Field Office you have contacted.
❑ Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
A review of federal and state databases revealed that there are no threatened or endangered species currently listed by
the U.S. Fish and Wildlife Service ( USFWS) for Alamance County. In addition, a review of the N.C. Natural Heritage
Program (NCNHP) database (revised April 2014) shows no record (historic /present) of threatened or endangered species
within the vicinity of the proposed project.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat?
❑ Yes ® No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
A review of the EFH Mapper found on the NMFS website was used to determine the absence of essential fish habitat near
either project study area.
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal
governments have designated as having historic or cultural preservation
❑ Yes No
status (e.g., National Historic Trust designation or properties significant in
North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
A review of the State Historic Preservation Office (SHPO) HPOWEB GIS service records shows that there will be no
impacts to historic or archaeological resources along the proposed corridors. Based on information from the HPOWEB
GIS service, there is one National Register of Historic Places (NR) property approximately 3000' south of the project
corridor, and two NR study list (SL) properties located approximately 2,200' and 3,300' southeast of the project corridor.
Given the nature of the project, and the location within an existing maintained utility easement, it is anticipated that the
proposed project will have no effect on any NR or SL property.
8. Flood Zone Designation (Corps Requirement)
Sa. Will this project occur in a FEMA- designated 100 -year floodplain?
® Yes ❑ No
8b. if yes, explain how project meets FEMA requirements: The project will result in the replacement and installation of new
gravity sanitary sewer line; therefore we do not anticipate that this project will create any rise in the 100 -year floodplain.
8c. What source(s) did you use to make the floodplain deter ination? FIRM, P el 8885 (Effective September 6, 2006).

1. The Corps of Engineers believes that there may be jurisdictional waters of the
United States on the subject site, and the permit applicant or other affected party
who requested this preliminary JD is hereby advised of his or her option to
request and obtain an approved jurisdictional determination (JD) for that site.
Nevertheless, the permit applicant or other person who requested this
preliminary JD has declined to exercise the option to obtain an approved JD in
this instance and at this time.
2. In any circumstance where a permit applicant obtains an individual permit, or
a Nationwide General Permit (NWP) or other general permit verification requiring
"pre- construction notification" (PCN), or requests verification for a non - reporting
NWP or other general permit, and the permit applicant has not requested an
approved JD for the activity, the permit applicant is hereby made aware of the
following: (1) the permit applicant has elected to seek a permit authorization
based on a preliminary JD, which does not make an official determination of
jurisdictional waters; (2) that the applicant has the option to request an approved
JD before accepting the terms and conditions of the permit authorization, and
that basing a permit authorization on an approved JD could possibly result in less
compensatory mitigation being required or different special conditions; (3) that
the applicant has the right to request an individual permit rather than accepting
the terms and conditions of the NWP or other general permit authorization; (4)
that the applicant can accept a permit authorization and thereby agree to comply
with all the terms and conditions of that permit, including whatever mitigation
requirements the Corps has determined to be necessary; (5) that undertaking
any activity in reliance upon the subject permit authorization without requesting
an approved JD constitutes the applicant's acceptance of the use of the
preliminary JD, but that either form of JD will be processed as soon as is
practicable; (6) accepting a permit authorization (e.g., signing a proffered
individual permit) or undertaking any activity in reliance on any form of Corps
permit authorization based on a preliminary JD constitutes agreement that all
wetlands and other water bodies on the site affected in any way by that activity
are jurisdictional waters of the United States, and precludes any challenge to
such jurisdiction in any administrative or judicial compliance or enforcement
action, or in any administrative appeal or in any Federal court; and (7) whether
the applicant elects to use either an approved JD or a preliminary JD, that JD
will be processed as soon as is practicable. Further, an approved JD, a proffered
individual permit (and all terms and conditions contained therein), or individual
permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331,
and that in any administrative appeal, jurisdictional issues can be raised (see 33
C.F.R. 331.5(a)(2)). If, during that administrative appeal, it becomes necessary
to make an official determination whether CWA jurisdiction exists over a site, or
to provide an official delineation of jurisdictional waters on the site, the Corps will
provide an approved JD to accomplish that result, as soon as is practicable.

This preliminary JD finds that there "may be "waters of the United States on the
subject project site, and identifies all aquatic features on the site that could be
affected by the proposed activity, based on the following information:

Remarks:
Surface water was present within a floodplain depression as well as within the sanitary sewer easement.
Although not in the vicinity of the data form location, drainage patterns were observed in a number of locations throughout the overall wetland area.
Hydrology likely influenced predominately by groundwater seepage from the adjacent hill slope. Construction and maintenance of the sanitary sewer
easement is also a likely contributor to hydrology by creating soil compaction in clayey soils.
Additionally, over -bank flooding of the Haw River is likely a contributor of hydrology, although not as influential.

Notes: Stream S3 is a rocky perennial channel that lies within a topographic
crenulation. A good baseflow was present during the site visit with the stream
banks being deeply excised. The banks are approximately 5' deep and 12' wide.
There were no benthos observed though a recent rainfall had occurred prior to the

Notes: Stream S4 is a weak intermittent channel that lies within a
crenulation. Heavy iron oxidation bacteria is present in the stream. S4 begins at
a 12" CMP protrucing from a hillside. S4 may drain a quarry /landfill. The system is
heavily degraded due to large amounts of trash and debris. Stream S4 flows over
the easement near a large manhole pad.

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points
to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the
characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a
characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the
comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture
into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each
reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the
highest quality.
Total Score (from reverse): 49 Comments:
Stream S1 is a large perennial channel in a topographic valley. S1 has very rocky substrate with occasional boulders in the
stream's bed. S1 has strong in- channel structures. The bank full width is approximately 25'. The channel appears strongly
established. Burlington experienced approximately 0.19" of rain within 48 hours prior to the field site visit.

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points
to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the
characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a
characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the
comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture
into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each
reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the
highest quality.
Total Score (from reverse): 40 Comments:
Stream S3 is a rocky perennial channel that lies within a topographic crenulation. A good baseflow was present during the site_
visit with the stream banks being deeply excised. The banks are approximately 5' deep and 12' wide. There were no benthos
observed though a recent rainfall had occurred prior to the site visit. A few mollusks were observed in the stream.

The purpose of this letter is to notify you that the North Carolina Ecosystem Enhancement Program (NCEEP) is willing to accept
payment for compensatory mitigation for impacts associated with the above referenced project as indicated in the table below. This
letter replaces the letter issued April 16, 2014. Please note that this decision does not assure that participation in the NCEEP will be
approved by the permit issuing agencies as mitigation for project impacts. It is the responsibility of the applicant to contact these
agencies to determine if payment to the NCEEP will be approved. You must also comply with all other state, federal or local
government permits, regulations or authorizations associated with the proposed activity including SL 2009 -337: An Act to Promote
the Use of Compensatory Mitigation Banks as amended by
S.L. 2011 -343.
This acceptance is valid for six months from the date of this letter and is not transferable. If we have not received a copy of the
issued 404 Permit /401 Certification /CANIA permit within this time frame, this acceptance will expire. It is the applicant's
responsibility to send copies of the permits to NCEEP. Once NCEEP receives a copy of the permit(s) an invoice will be issued based
on the required mitigation in that permit and payment must be made prior to conducting the authorized work. The amount of the In-
Lieu Fee to be paid to NCEEP by an applicant is calculated based upon the Fee Schedule and policies listed at www.nceep.net.
Based on the information supplied by you in your request to use the NCEEP, the impacts that may require compensatory mitigation
are summarized in the following table. The amount of mitigation required and assigned to NCEEP for this impact is determined by
permitting agencies and may exceed the impact amounts shown below.
