Subject: Alamance County, Replacement of two 81" X 59" X 40' ft culverts with two 81"X 59* X 60 ft
culverts on Cates Loop Rd (SR 1909)
Project XUuxber # B.200114 8-
To Whom It May Concern:
The North Carolina Department of Transportation (NCDOT) proposes to replace two culverts on
Cates Loop Road (SR1909) in Alamance County in order to improve traffic safety. This activity will
result in impacts to an unnamed tributary of Quaker Creek. In an effort to obtain the necessary
permits for the subject culvert replacements, we are providing a pre-construction notification
application with supporting documentation. We believe this project can be permitted under the
Nationwide Permit numbers 3 and 33. This application is intended as a request for formal written
authorization from the USCOE for NWP 3 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 the
appropriate General Water Quality Certificates.
The following information is being provided to satisfy conditions of General Water Quality
Certification.

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.

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
Culvert replacement activities are necessary to maintain traffic safety. 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 (including a pre construction meeting with the Division Environmental
Officer.
IEK. Mitigation
Page 5 of 9
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 minim4l. 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, dvailable at
http://h2o.enr,state.ne.us/ncwetlands/strmgide,btml.
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 nrovided.
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
species or their habitats or essential fishery habitats occur in the protect area. The protect is
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 b"://h2o.cnr.state.nc.us/,,vrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:

- XI.- 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.
