DWQ Project No. 040200
Pipe replacement on SR 1960 (Lloydtown Road)
APPROVAL of 401 Water Quality Certification with Additional Conditions
Mr. J.M. Mills, Division Engineer
NCDOT Division 7
P.O. Box 14996
Greensboro, NC 27415-4996
Dear Mr. Mills:
You have our approval, in accordance with the attached conditions and those listed below, to incur the
170 linear feet of impacts to two unnamed tributaries to Cane Creek. NCDWQ understands that these
impacts are necessary in order to replace two pipes on SR 1960 (Lloydtown Road) in Orange County.
The project shall be constructed in accordance with your application dated January 12, 2004. After
reviewing your application, we have decided that these impacts are authorized by General Water Quality
Certification Nos. 3404 and 3366, corresponding to the U.S. Army Corps of Engineers Nationwide Permit
Numbers 14 and 33. This approval shall also act as your Authorization Certificate as required within the
Neuse River Area Protection Rules (15A NCAC 2B .0233). In addition, you must acquire any other
federal, state or local permits before you proceed with your project including (but not limited to):
Sediment and Erosion Control, Non-Discharge and Water Supply Watershed regulations. This approval
will expire with the accompanying 404 permit unless otherwise specified in the Water Quality
Certification.
This approval is valid solely for the purpose and design described in your application (unless modified
below). Should your project change, you must notify the DWQ in writing and submit a new application.
If the property is sold, the new owner must be given a copy of this Certification and approval letter, and is
thereby responsible for complying with all the conditions. If total wetland fills for this project (now or in
the future) exceed one acre, or of total impacts to streams (now or in the future) exceed 150 linear feet,
compensatory mitigation may be required as described in 15A NCAC 2H.0506 (h) (6) and (7). For this
approval to be valid, you must follow the conditions listed in the attached certification and any additional
conditions listed below.
1. Erosion and sediment control practices must be in full compliance with all specifications
governing the proper design, installation and operation and maintenance of such Best
Management Practices in order to protect surface water standards:
¦ The erosion and sediment control measures for the project must be designed, installed, operated,
and maintained in accordance with the most recent version of the North Carolina Sediment and
Erosion Control Planning and Design Manual.
¦ The design, installation, operation, and maintenance of the sediment and erosion control measures
must be such that they equal, or exceed, the requirements specified in the most recent version of
the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on
all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or
leased borrow pits associated with the project.

¦ If there are borrow pit sites, the erosion and sediment control measures must be designed,
installed, operated, and maintained in accordance with the most recent version of the North
Carolina Surface Mining Manual.
¦ Any reclamation measures and implementation must comply with the reclamation in accordance
with the requirements of the Sedimentation Pollution Control Act.
2. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas
beyond the footprint of the impacts depicted in the Preconstruction Notice Application. All
construction activities, including the design, installation, operation, and maintenance of sediment
and erosion control Best Management Practices, shall be performed so that no violations of state
water quality standards, statutes, or rules occur.
3. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum
extent practicable. If placement of sediment and erosion control devices in wetlands and waters
is unavoidable, they shall be removed and the natural grade restored within six months of the date
that the Division of Land Resources has released the project.
4. NCDOT is encouraged to use onsite vegetation and materials for streambank stabilization when
practicable.
5. Riparian vegetation must be reestablished within the construction limits of the project by the end
of the growing season following completion of construction.
6. Stormwater should be directed to vegetated buffer areas, grass lined ditches or other means
appropriate to the site for the purpose of pre-treating stormwater runoff, and must not be routed
directly into streams. Mowing of existing vegetated buffers is strongly discouraged, so that they
may be utilized for stormwater sheet flow.
7. Where fish passage is present or where significant aquatic life may be present upstream (and
where practicable), culverts should be oversized and buried to prevent perched culverts. If
oversized piping cannot restore aquatic life passage by reconnecting the stream ecosystem, riprap
installation should be accomplished in a manner to provide or restore water channels downstream
to help facilitate aquatic life movement.
8. Where practicable, culverts that are less than 48-inch in diameter should be buried to a depth
equal to or greater than 20% of their size to allow for aquatic life passage. Culverts that are 48-
inch in diameter or larger should be buried at least 12 inches below the stream bottom to allow
natural stream bottom material to become established in the culvert following installation and to
provide aquatic life passage during periods of low flow. These measurements must be based on
natural thalweg depths. This may require increasing the size of the culvert to meet flow
conveyance requirements. If any of the existing pipes are perched, they shall be removed and
replaced, and re-installed correctly, unless demonstrated that this is topographically unfeasible.
All waters must flow through without freefalling or damming on either end of the culverts during
low flow conditions, to maintain aquatic life and/or fish passage.
9. The dimension, pattern and profile of the stream, above and below the crossing, should not be
modified by widening the stream channel or reducing the stream depth. Disturbed floodplains
and streams should be restored to natural geomorphic conditions.
10. Riprap should be minimized and installed in a manner so as not interfere with aquatic life passage
during low flow conditions. Riprap placed for bank stabilization should be limited to the
streambank below the high water mark and vegetation should be used for stabilization above the
high water mark.
11. If concrete is used, work must be accomplished so that wet concrete does not contact the stream
water. This will lessen the chance of altering the stream's water chemistry and causing a fish kill.
12. Heavy equipment must be operated from the banks rather than in the stream channel in order to
minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream.
13. All mechanized equipment operated near surface waters must be regularly inspected and
maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or
other toxic materials.

14. The presence of equipment in the channels must be minimized. Under no circumstances must
rock, sand or other materials be dredged from the wetted stream channel under authorization of
this permit, except in the immediate vicinity of the culverts.
15. Removal of vegetation and grading and backfilling at the stream crossing and adjacent to stream
should be minimized. Native trees and shrubs should be planted along the streambank to
reestablish the riparian zone and provide long-term erosion control and cover for fish and wildlife
in the vicinity of the road crossing and along the streams within the dedicated rights of way.
Backfill materials should be obtained from upland sites.
16. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certificate
of Completion" form to notify NCDWQ when all work included in the §401 Certification has
been completed. The responsible party shall complete the attached form and return it to the
401/Wetlands Unit of the NC Division of Water Quality upon completion of the project NCDOT
is strongly advised to send in photographs upstream and downstream of each structure to
document correct installation.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing.
You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written
petition which conforms to Chapter 150B of the North Carolina General Statutes to the Office of
Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its
conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water
Act. If you have any questions, please telephone Ms. Beth Barnes at 919.715.8394.

Subject: Orange County, Pipe Replacement on Lloydtown Road (SR 1960)
Project Number # 7C.068041
To Whom It May Concern:
The North Carolina Department of Transportation (NCDOT) proposes to replace a 22 ft X 18 inch
RCP with a 52 ft X 30 inch RCP on Lloydtown Rd (SR 1960) in Orange County. The work is
proposed in order to increase lane width and improve traffic safety. This activity will result in
impacts to an unnamed tributary of Cane Creek. In an effort to obtain the necessary permits for the
subject pipe extension, we are providing a pre-construction notification application with supporting
documentation. We believe this project can be permitted under the Nationwide Permit Numbers 14
and 33. This application is intended as a request for formal written authorization from the USCOE
for NWP 14 and 33. This application is also intended as a request for written authorization from the
NC Division of Water Quality for minor road crossing under General Water Quality Certificates
#3376 and #3404.
The following information is being provided to satisfy conditions of General Water Quality
Certification.

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.
Pine replacement and widenina activities are necessary to increase travel lane and shoulder width
to current construction standards. Impacts will be minimized by strict enforcement of Best
Management Practices for the protection of wetland and surface waters, restrictions against the
staging of equipment in or adjacent to waters of the US, and coordination with the Division
Environmental Officer.

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 March 9, 2000, 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 NCWRP 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
littp:Hii2o.enr. state. nc.us/ncwetiands/strm,Qide.litnil.
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.
A finding of insignificant impact is anticipated. Cumulative impacts are less than 150 feet.
The maximum amount of impact to a single stream is 56 linear feet. No Outstanding
Resource Waters federally protected species or their habitats, or essential fishery habitats
occur in the project area. The project is not located in a High Quality Water.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at httn://h2o.encstate.nc.uqNN,rp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:

Yes ? No ?
X. Proposed Impacts on Riparian and Watershed Buffers (DWQ Only)
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.
