Subject: Town of Louisburg
NW 12 Sewer Line- Project N 2147-- 6
Franklin County NVY%
A site visit for this project has not b en formed. The
new sewer line will run parallel to the exist'ng tie along the
same right-of-way as much as possible. Erosio nd.sedimentation
issues have been adequately addressed. A 40 foot corridor has
been requested. This should only be used where topography
requires the use of this width. Otherwise, the NW 12 condition of
minimizing the impact shall stand. 90 degree crossings are used
for all tributary crossings.
Waterways to be impacted are Fox Creek: class C NSW; and
wetlands adjacent to the Tar River: class WS-III NSW. The RRO
recommends a concurrence notice with the NW 12 be issued, once
all required items and public notice requirements have been
addressed.

Re:
Request for Nationwide Permit
Sewer Line Installations at the New WI'P
Tarn of Louisburg, North Carolina
SRF Project No. CS370397-04 / P&W Project
Gentlemen:
Please find enclosed seven (7) copies of the application and
supporting documentation for a Nationwide Permit to cover the
installation of the two proposed sewer mains at the Town of
Louisburg's Wastewater Treatment Plant. A general permit numbered
CESAW-0081-N000-049 has already been issued to cover the installation
of the sewer mains; however, the Engineers and DEM have determined
that the 20 foot corridor under the general permit will not be
sufficient to install the sewer mains due to relative deep depth of
the pipes. Two revised 8-1/2 x 11 plan sheets showing the proposed
mains are attached.
This project has been reviewed by the U.S. Fish and Wildlife Service,
the Department of Cultural Resources, the DEM Water Quality Planning
Section and the N. C. Wildlife Resources Commission. The comments froan
these agencies can be found in Section "F" of the attached FONSI
(Finding of No Significant Impact) dated July 19, 1991. In addition,
the Division of Land Resources has approved the sedimentation and
erosion control plan, a copy of the approval letter is also attached.
The N.C. Division of Environmental Management has also issued approval
for this project, a copy of the January 02, 1992 letter of approval is
attached. An original permit has been forwarded to Mr. Eric Alsmeyer
of the U.S. Corps of Engineers, Raleigh Office for approval.
We trust this information will allow for the issuance of the
Nationwide Permit at your earliest convenience; however, if additional
information is needed or if there are any questions, please do not
hesitate to call us at 782-8300. This is a State Revolving Loan
Project and we request that a copy of the approval letter be forwarded
to Mr. Bill Hoffman with the Division of Environmental Management.

ATTAC Yfla4T NO. 1:
A. general permit No. CESAW-C081-N-000-049 was issued allowing the
sewer lines to be installed in a maximum corridor of 20 feet. It has
been determined by Peirson and Whitman Engineers and the North
Carolina Division of Environmental Management that the 20 foot
corridor is too confining to install the sewer mains due to rather
deep depths of the proposed sewer mains. It is therefore requested
that a National Permit be issued which would allow a maximum corridor
of 40 feet.
ATTACHMENT NO. 2:
The proposed sewer interceptor is to replace and parallel the old
existing sewer interceptor. There is no alternate route for the
interceptor since the existing sewer collection mains follow the low
lying drainage areas leading to the sewer treatment plant. The
existing and proposed interceptors cross Fox Swamp Branch at a 900
angle.
The proposed sewer outfall will also parallel the existing outfall
leading to the Tar River. The outfall is in a low lying area since
the wastewater treatment plant is located near the lowest point in
the local drainage basin.
The Contractor shall take special precautions to minimize the impacts
to the wetlands. The precautions are noted on the plan sheets,
copies of which are attached. In addition, the Contractor must
follow the approved sedimentation and erosion control plan. The
sedimentation and erosion control measures are also shown on the -
attached plan sheets. A copy of the approval letter is attached.

FINDING OF SIGNIFICANT IMF'AC"!' (FNSI)
CONSTRUCT NEW WASTEWkTER TREA`Ilv.FNT FACILITIES
Title VI of the amended Clean Water Act requires the review and approval of
environmental information prior to the construction of publicly-owned
wastewater treatment facilities financed by the State Revolving Fluid (SRF).
The proposed project has been evaluated for ccrpliancEe with the North
Carolina Environmental Policy Act and determined to be a major action which
will affect the environment.
Project Applicant: Louisburg, NC
Project Number: CS370397-04
Project Description: The proposed project consists of constructing
wastewater treatment facilities to treat 1.37 mgd.
The treatment plant will be designed to achieve
more stringent effluent limits.
Total Project Cost: $4,861,230
Revolving Loan Amount: $4,861,230
The review process did not indicate that significant adverse environmental
impacts would result from implementing the proposed project, and an
environmental impact statement (EIS) will not be required. The decision was
based on information in the facilities plan, a public hearing document, and
reviews by governmental agencies. An environmental assessment supporting
this action is attached. This FNSI ccanpletes the environmental review
record, wil-,ich is available for inspection at the State Clearinghouse.
No administrative action will be taken on the proposed project for at least
thirty days after notification of the FNSI is published in the North
Carolina F.nvirorT7-cnta1 Bulletin.

A. Proposed Facilities and Actions
Figure I shows the location of the proposed facilities, which are adjacent
tc) the existing treatment plant.
Treatment Facilities. The proposed project consists of providing
wastewater treatment facilities to handle 1.37 mgd. N,ajor improvements will
include a mechanically cleaned bar screen, an aerated grit and grease
removal unit, two oxidation ditches with an anaerobic basin, two final
clarifiers, chemical storage and feed equipment, tertiary filters,
disinfection and post-aeration facilities, a sludge digester, sludge
handling and disposal equipTent, a laboratory/operations building and a
maintenance building. The existing maid pump station will be renovated and
used as a part of the new treatment process. The existing secondary
clarifier and sand drying beds will also be incorporated into the new
treatment plant design. The effluent will continue to be discharged into
the Tar River.
B. Existing Environment
Topography and Soils. The Town of Louisburg is located in Fran}lin County
and the topography ranges from level to strongly rolling. The four soil
associations in the area are Appling, Appling-Louisburg, Appling-Durham, and
Bibb-Wehadkee-Roanoke. Ail of the associations with Appling soils are
generally well drained with sandy loam surface soils or subsurface subsoils.
Surface Waters. The Town of Duisburg is located in
T'-?e Tar River
V,aters (NSW) .
P.i,ver, a Class
_ the Tar River Basin.
and its tributaries have been declared Nutrient Sensitive
Louisburg's treatment plant discharges effluent into the Tar
°tqS-III" stream with a 7Q10 flaw of 14 cubic feet per second.

Water Supply. Louisburg receives its potable water frcrn the Tar River.
C. El-:istinc Wastewater facilities
1OFWn of I_ouisburn c-u? rently n?r.ates an 0.80 R)gd tricl:li.ng filter
pl-Lnt. The original 0.50 nKjd plant was constructed in 1959 and was upgrades:
and e_-,onded in 1979 to its present capacity. The effluent is discharged
into the Tar River. The ciigested sludge is normally land applied. If
;..c,n itions are unfavGr iljle, the sludge, is di ic_xi or. sand l)ecls, hauled to the
county landfill, and used as a :x:i l amencsrt in the final. cover. There- are
scre isolated dvAn-liing units within the `ibwn of Louisburg which are served
by individual septic tanks and drainfields. The sewerage system has been
evaluated and inflow is excessive. FX°teriorated lines have been identified
and the necessary corrections will be made to reduce the amoiuat of inflow
entering the collection system.

D. Need for Proposed Facilities and Actions
The 0.80 mgd trickling filter plant is hydraulically overloaded. it is also
in violation of the existing effluent limits of BOD.- = 30 mg/l and TSS =
30 ng/1. Additionally, the Tar River Basin has beef declared nutrient
sensitive and more stringent effluent limitations must be met. The
anticipated effluent limitations are as follows:
EF'FUJ EN`I' LIMTTATI=
EFFLUENT PARAMETERS Sumer Winter
Flow (MGD) 1.37 1.37
BOD (mg/1)
5 10 26
NH
N (mg/1.)
3 3 4
DO
(mg/1). 5 5
TSS (mg/1) 30 30
Fecal Coliform (#/100 ml.) 200 200
PH, standard unit 6-9 6-9
Phosphorus (mg/1) 2 2
Total Nitrogen (mg/1) 4 8
Chlorine (ug/1) 28 28
Oil & Grease (mg/1) 30 30
The existing plant was not designed to meet the effluent limitations listed
above, and a Special Order by Consent (SOC) regtLixes the Town of Louisburg
to upgrade its treatment plant. Therefore, it is necessary to construct the
proposed facilities and remove infiltration/inflow frcan the collection
system. This action will improve the quality of treated effluent to be
discharged into the Tar River and allow Louisburg to continue to develop in
an orderly manner.
The existing Town of Louisburg's population is 4,294, and the twenty-year
projected figure is 5,794. The existing plan has a permitted capacity of
0.80 mgd and the proposed facility will have a capacity of 1.37 nod.
E. Alternatives Analvsis
`Die Town of Louisburg upgraded and e_panded its wastewater treatment plant
in 1979. The facility is riot operatinq in ca.Tpliance with the existinu
;:PI)F(; permit. Additionally, the deterioration of water quality in the Tar
lover has, prca pted the need for nY)re stringent levels of treatmrent. The
Town of Louisburg exanusled ti-ie no-action"-alternative and rejected this
approach due to possible inj?osition of civil penalties as a result of permit
violations. A land application system was considered, and this alternative
would require the purchase of a substantial amount of land. This is not the
Rost cost-effective alternative to implement. The town examined the optimtun
level of treatment that could be achieved from the existing treatment plant
and decided that the age of most of the equipment precluded the facility
from meeting more stringent effluent limitations. Replacing and repairing
the equipment would also not result in increased plant
-2-

cupaciLy. Another alternative evaluated consisted of constructing new
facilities adjacent to the existing treatment plant. Score of the existing
equipment would be incorporated into the new design, and this is the most
cost-effective and the selected alternative.
F. Environmental Consequences, Mitigative Measures
New facilities 4.-ill be constructed at a site which is adjacent to the
existing treatment plant. Some of the existing facilities will be
incorporated into the new plant design. The location is near the Tar
River. The Town of Louisburg purchased 49.66 acres of land and
approximately 4.5 acres of the total acreage will be required to construct
the new facilities. The proposed treatment plant site is located on the
fringe of the 100-year floodplain and approximately 3.5 acres of land in the
floodplain will be disturbed to acccumodate the treatment facilities. The
U.S. Fish and Wildlife Service does not object to the proposed project. An
archaeological investigation has been conducted and the Department of
Cultural Resources concurs with the reccnnvendation that the proposed project
will not have a significant impact on archaeological resources. The Water
Quality Planning Section indicated that exfiltration could cause a
deterioration of water quality in the Tar River. Therefore, the town has
comnitted to funding a program which will identify and correct deteriorated
sewer lines. 1"rye North Carolina Wildlife Resources Conu ission expressed
some concerns about the proposed project and the following mitigative
measures will be implemented to protect the environment:
1. Approximately 4.5 acres will be required to construct the proposed
facilities and the remaining 45.16 acres will be preserved by the
Town of Louisburg through a conservation easement.
2. All treatment facilities, including the existing and the proposed,
will be protected from flooding without encroachment into wetlands.
3. There will be no ground disturbing activities in wetlands and no
clearing in floodplain beyond the required 3.5 acres. An
undisturbed buffer will be maintained between wetlands and upland
areas. The TcNrn of Louisburg will consult with the North Carolina
Vdl.dli e Resources Ccurdssion about plantinc high wildlife value
trees.
4. An erosion and sedimentation control plan will be ii-plementf-,d and
i!vintained until disturbed soils have been full", Stabilized with
vegetative cover..
5. The U.S. Army Corps of Engineers will evaluate the site to
deteri-nine the exact boundaries of wetland areas.
6. The Town of Louisburg will be required to participate in the FFMA
Flood Insurance Program.
-3-

Mitigative measures will be implemented and const--uction activities will be
conducted in accordance with appropriate guidelines and required
regulations. The project will allow orderly development for Louisburg and
protect water quality in the Tar River.
G. Public Participation, Sources Consulted
A public hearing was held Aprii 8, 1991 on the amended Louisburg 201
Facilities Plan. The hearing covered the problens of the existing
facilities, the proposed alternative for solving the problems, and the costs
to implement the selected plan. No opposition to the proposed project has
been expressed. The average user currently pays $18.15 per month for sewer
service and the proposed improvements will result in an increase to
approximately $33.23 per month for the typical custcmer residing within the
Town of Louisburg. The user charges will be high and steps have been taken
to eliminate any unnecessary construction which would result in additional
costs to the project. The town is required to construct costly wastewater
treatment facilities in order to comply with the NPDES permit and to protect
water quality in the Tar River.

Date Received: 8-14-91 & 8-28-91
Date Processing Initiated: 8-14-91
New Submittal (X) Revised ( )
Dear Ms. Allen:
This office has reviewed the subject Erosion and Sedimentation Control
Plan. We find the plan to be acceptable and hereby issue this letter of
approval. If any modifications, performance reservations, or recommendations
are applicable, a list is enclosed and is incorporated as a part of this
letter of approval. If any modifications are not incorporated into the plan
and implemented in the field, the site will be in violation of the
Sedimentation Pollution Control Act of 1973 (NCGS 113A-61.1).
Please be advised that Title 15A, North Carolina Administrative Code,
4B.0018(a) requires that a copy of the approved plan be on file at the job
site. Also, please consider this letter as notice in accordance with the
requirements of North Carolina General Statute (hereinafter NCGS) 113A-61.1
concerning our right to perform periodic inspections to ensure compliance with
the approved plan.
North Carolina's sedimentation pollution control program is performance
oriented, requiring protection of the natural resources and adjoining
properties. If at any time during this project it is determined that the
Erosion and Sedimentation Control Plan is inadequate to meet the requirements
of the Sedimentation Pollution Control Act of 1973 (NCGS 113A-51 through 66),
this office may require revisions in the plan and its implementation to ensure
compliance with the Act.
