Subject: Orange County, Culvert Replacement on Mt. Herman Church Road (SR 1713)
Project Number # 7B.200111
To Whom It May Concern:
The North Carolina Department of Transportation (NCDOT) proposes to replace a severely
damaged culvert on Mt. Herman Church Road in Orange County in order to prevent collapse of the
road and to maintain traffic safety. In an effort to obtain the necessary permits for the subject
culvert replacement, we are providing a pre-construction notification application with supporting
documentation. The work is necessary because of the great potential for the collapse of the road.
We believe this project can be permitted under the Nationwide Permit numbers 3 and 33.
The following information is being provided to satisfy conditions of General Water Quality
Certification.

MINIMIZATION INFORMATION
Impacts will be minimized by strict enforcement of Best Management Practices for the protection of
surface waters and wetlands, restrictions against the staging of equipment in or adjacent to waters
of the US, and coordination (including a pre-construction meeting) with the Division Environmental
Officer.
MITIGATION INFORMATION
Stream mitigation is not anticipated, as the impacts to any individual stream do not exceed 150 feet
Wetland mitigation is not anticipated, as wetland impacts do not exceed 0.10 acres and do not
occur in a unique natural wetland.

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.
Culvert replacement activities are necessary to maintain travel safety. Impacts will be minimized
by strict enforcement of Best Management Practices for the protection of wetland and surface
waters restrictions against the stag of equipment in or adjacent to waters of the US, and
coordination (including a pre-construction meeting) 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.
Page 5 of 8
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
http://h2o.enr.state.nc.us/ncwetlands/strmaide.html.
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.
A finding of insignificant impact is anticipated, therefore a mitigation plan is not provided.
Cumulative impacts are less than 150 feet The maximum amount of impact to a single
stream is approximately 20 linear feet No Outstanding; Resource Waters federally protected
apecies 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). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
