Attention: Mr. John Thomas Ms. Cyndi Karoly
Subject: Nationwide Permit 14 and General Certification 3404, Linear Transportation
Crossing, Pre-Construction Notification for Proposed Culvert Replacement for
Ballinger Road Extension at Piedmont Triad International Airport, Greensboro,
Guilford County, North Carolina
On behalf of the Piedmont Triad Airport Authority (PTAA) notice of intent to use Nationwide
Permit 14 and General Water Quality Certification (WQC) 3404 pursuant to Sections 404 and
401 of the Clean Water Act (CWA) and 15A NCAC 2H.0500 is hereby provided for unavoidable
impacts to jurisdictional waters of the U.S. Approximately 100 linear feet of perennial stream
channel will be permanently impacted by replacement of an existing culvert during construction
of the extension of Ballinger Road. The purpose of the proposed roadway extension is to
provide access to an approximately 70.63-acre site proposed for a future airport development
project. The 70.63-acre development site includes no Section 404 jurisdictional waters and is
buffered from adjacent streams by 100 feet. The new access provided by the proposed extension
of Ballinger Road to Radar Road is required due to the recent closure of Stage Coach Trail and
consequent "dead-end" of Ballinger Road.
The proposed culvert replacement will facilitate access to the adjacent 70.63-acre airport
development site in the least environmentally detrimental way. The unavoidable stream crossing
site was selected at an existing dirt road crossing where the stream, an unnamed tributary (UT) to
Horsepen Creek, flows though an approximately 30-foot section of 2-foot diameter corrugated
plastic pipe (CPP). The proposed roadway extension will replace this pipe at the same location
with a 130-foot long, 6-foot diameter reinforced concrete pipe (RCP) with bottom submerged
below the elevation of the streambed to allow low flow passage of water and aquatic life. The
total impacts to the stream will be minimal and will not have a significant impact to the quality
of jurisdictional waters, therefore, compensatory stream mitigation is not proposed.
The limits of jurisdictional Waters of the U.S. were surveyed and verified by the U.S. Army
Corps of Engineers (USACE) in Action ID 199820910 (copy enclosed) on July 29, 1999. Based
on recent field review and available mapping [U.S. Geological Survey (USGS) 7.5-Minute
Topographic Quadrangle, U.S. Department of Agriculture (USDA) Natural Resources
Conservation Service (MRCS) Soils Survey, U.S. Fish and Wildlife Service (USFWS) National
Wetlands Inventory, and 2005 Color Aerial Photograph, enclosed], re-verification of the 1999
jurisdictional determination is requested concurrent with this Pre-Construction Notification
(PCN) based on no change in jurisdiction of the previously surveyed stream channel.

Mr. John Thomas; Ms. Cyndi Karoly
Page 2 of 3-
North Carolina Department of Environment and Natural Resources (NCDENR) Division of
Water Quality (DWQ) Stream Identification Form and USACE Stream Quality Assessment
Worksheet were updated/revised (completed forms enclosed) based on current field conditions
and regulatory updates to the versions of these forms used during the 1999 jurisdictional
determination. The stream (evaluated for 100 feet upstream and 100 feet downstream of the
existing culvert) appears marginally perennial, scoring 29.5 using the DWQ method, with a
macrobenthic population dominated by amphipods and midge larvae. The stream quality was
assessed at a moderate 55 (out of a possible 100) using the USACE form.
The USFWS lists the American bald eagle (Haliaeetus leucocephalus) as the only federally
protected species for Guilford County. The applicant has also considered all federal and state
listed species within the project study area, which included the adjacent 70.63-acre site to be
developed. It appears that the project site does not contain any federally-listed endangered or
threatened species, their formally designated critical habitat, or species currently proposed for
listing under the Endangered Species Act. Further, based on recent field review and previous
regulatory reviews, we are aware of no historic, cultural, or archaeological resources that would
be affected by the project.
Temporary construction impacts due to erosion and sedimentation will be minimized through
implementation of a stringent erosion control schedule and the use of Best Management
Practices (BMPs). The contractor will be required to follow contract specifications pertaining to
erosion control measures as outlined in 23 CFR 650 Subpart B and Article 107-13 entitled
"Control of Erosion, Siltation, and Pollution" (North Carolina Department of Transportation
[NCDOT], Specifications for Roads and Structures). These measures include the use of dikes,
berms, silt basins, and other containment measures to control runoff; elimination of construction
staging areas in floodplains and adjacent to waterways; re-seeding of herbaceous cover on
disturbed sites; management of chemicals (herbicides, pesticides, de-icing compounds) with
potential negative impacts on water quality; and avoidance of direct discharges into streams by
catch basins and roadside vegetation.
Increased impervious surface area resulting from development of the adjacent 70.63-acre site
would result in a corresponding increase in surface water runoff in the immediate area of the
project site. The stormwater controls required to be constructed by PTAA under its Water
Supply Watershed Rules will not only help to capture the runoff from the new impervious
surface, but also from existing impervious surfaces within the same drainage area. Therefore,
even with significant storm events, there will be no increase in volume reaching downstream
surface waters.
Prior to the commencement of construction, a Sedimentation and Erosion Control Plan for the
roadway project will be submitted to NCDENR, and PTAA will obtain a Sedimentation and
Erosion Control Permit and accompanying NPDES Construction Permit as needed. Potential
impacts to surface water quality as a result of the roadway construction activities will be
effectively mitigated through adherence to the approved Sedimentation and Erosion Control
Plan, to permit requirements, and to standard NCDOT BMPs.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
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. The stream crossing is
unavoidable due to the southeasterly orientation and location of the iurisdictional
channel. The proposed crossing site was selected at an existing dirt road /
culvert in order to minimize impacts to the stream channel. The replacement
pipes will be appropriately sized and located to allow low flow passage of water
water quality.
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 January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
Updated 1 U1/2005
Page 5 of 8
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 NCEEP 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
htty://h2o.enr.state.nc.us/ncwetlands/strmgide.htmi.
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.
The total impacts to the stream will be minimal and will not have a significant
impact to the quality of jurisdictional waters, therefore, compensatory stream
mitigation is not proposed.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.nc.us/wM/index.htm. If use of the NCEEP is proposed, please

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): 7s Comments:
Evaluator's Signature Date 1-10-9M7
This channel evaluation form is intended to be us d only as a guide to assist landowners and environmental professionals in
gathering the data required by the United States Army Corps of Engineers to make a preliminary assessment of stream
quality. The total score resulting from the completion of this form is subject to USACE approval and does not imply a
particular mitigation ratio or requirement. Form subject to change - version 06/03. To Continent, please call 919-876-8441 x 26.
