Dear Mr. Shern,
Re: Pre-Construction Notification for
Nationwide Permit No. 14
City of Raleigh Solid Waste Transfer Facility
Raleigh, Wake County, NC
H&S No. 30579-000
On behalf of the City of Raleigh Department of Solid Waste Services, we are pleased to
submit this Pre-Construction Notification and supporting documentation for the construction of
the City's Solid Waste Transfer Facility. The site is owned by the City of Raleigh, who has
retained Hazen and Sawyer to prepare this Notification. Hazen and Sawyer has subcontracted
with EcoScience Corporation to complete the delineation of jurisdictional areas. The Owner
contact for this project is Mr. Fred Battle, Director of Solid Waste Services. He can be contacted
at 919-831-6073.
Project Background
The proposed Solid Waste Transfer Facility is to be constructed on part of the City's closed
Wilders Grove Landfill site. The Transfer Facility is located on a part of the site previously
owned by Pike Electric Co. and developed in the 1970's. The City purchased the parcel, and
through recombination survey, added it to the 259-acre Wilders Grove Landfill parcel. There is
no waste disposed on the Transfer Facility site. No permits for jurisdictional areas have been
issued for the Wilders Grove Landfill site.
The development includes widening of the existing paved access road and replacing and
lengthening the existing culvert to accommodate truck traffic and to provide safe sight lines for
drivers as they enter the facility. The roadway must be widened and reconstructed to safely serve
the projected truck traffic. The existing roadway and culvert are in disrepair and cannot safely be
incorporated into the project in their current state. The existing 76-ft long 36-inch diameter
culvert is being replaced by dual 36-inch diameter culverts to safely pass the 25-year 24-hour
design storm. The total length of the new culverts will be 110-feet. The existing access road

crosses a stream which is fed from existing roadside ditches and from the discharge of a sediment
basin.
Proposed Impacts
The jurisdictional areas were determined by EcoScience Corporation in February 2007. Avery
low quality naturalized jurisdictional stream, originally excavated as the culvert discharge, is
identified in parts of the project area. Replacement of the existing culvert and widening of the
road will result in the following impacts:
• Streams: 55-linear feet (0.004-acre)
•'• Wetlands: None
• Riparian Buffers: Zone 1: 1070 square feet Zone 2: 180 square feet
Riparian Buffer limits were established during a NCDWQ field call dated March 7, 2007. This
information is included in this submittal.
Impact Justification (Avoidance and Minimization)
The proposed impacts to jurisdictional areas are minimal and represent the minimum practical
impact for the proposed project. The proposed culverts are the minimum length needed to serve
the new roadway. Minimal widening of the existing channel is anticipated to allow installation
of the dual culverts, but only in the naturalized channel formed b.y excavation for the original
culvert.
In order to minimize the impacts to jurisdictional areas from additional earth fill associated with
the new roadway, the new roadway will be constructed at the same elevation as the existing
roadway.
Mitigation
Due to the very low quality of jurisdictional stream impacted and the very low total impact to the
stream, no mitigation is proposed. Riparian Buffer impacts are below the notification thresholds.
Information Included with the Pre-Construction Notification for Nationwide Permit No. 14

represent the minimum impact to the stream while providing adequate roadway width and
sight distances (sight triangle) to safely accommodate expected two-way truck traffic.
Alignment of existing road is maintained to extent practical to minimize need to further
lengthen culvert. Existing roadway elevation is maintained in order to minimize impacts
from earthwork related to the roadway embankment.

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
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 atached 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 (see DWQ website for most current
version.).
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.
No mitigation is nronosed. Stream channel is very low quality and low function,
manmade channel draining a stormwater basin and roadside ditches. Stream is lacking
pattern, structures and has a homogenous stream bed of sand and gravel. Stream has
limited habitat for macrobenthic fauna.
Updated 11/1/2005

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

XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (norrdischarge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Wastewater generated on pro,~ect site is conveyed to the City's sanitary sewer system by
means of a dedicated dump station
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wefland Rules (1 SA NCAC 2H .0500) or any Buffer Rules?
Yes ^ No
Is this an after-the-fact permit application? Yes ^ No
XIV. Cumulative Impacts (required by DWQ)
Updated 11/1/2005
Page 12 of 13

Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ^ No
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
htt~//h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: Site is
currently developed. Proposed improvements will not o en anY new area for development
or result in further jurisdictional impacts.
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).

Re: Results of an On-site Environmental Investigation
City of Raleigh Solid Waste Transfer Facility, Wake County, NC
Dear John:
07-333
EcoScience Corporation (ESC) personnel conducted an environmental investigation at the above-
mentioned site on Friday, February 2 and Monday, February 5, 2007. This letter summarizes the
findings of the investigation.
Physical Features
Wilders Grove landfill is located in a developing commercial/industrial area in east Raleigh just
north of Crabtree Creek and east of the I-440 beltline (Figure 1). The area of interest of this
investigation is located in the northeast corner of a facility characterized by a gravel parking lot and
service buildings associated with an existing solid waste transfer facility. The transfer facility is
bounded on all sides by mixed pine/hardwood forest. The specific area of interest of this
investigation (site) is the vicinity of a bend in the access road into the northwest corner of the solid
waste transfer facility yard. The site is focused on the linear depression, upstream and downstream
of a culvert crossing under this bend in the road.
The terrain is characterized by a general slope downward to the south to the floodplain of Crabtree
Creek. A linear depression, oriented in a north-south axis, occurs northeast and southwest of the
access road, guiding runoff southward to the Crabtree Creek floodplain. The northern depression
contains a single perennial stream. The southern depression contains one perennial stream and one
ephemeral channel. Crabtree Creek is a tributary within the Neuse River basin. Site elevations range
from a high of approximately 190 feet (north of the gravel entrance road to the transfer facility) to a
low of approximately 180 feet (south of the gravel entrance road).
According to the county soil survey, the site contains three soil mapping units: Appling sandy loam
(2 to 6 percent slopes), Appling sandy loam (6 to 10 percent slopes), and Faceville sandy loam (2 to
6 percent slopes). The National Resources Conservation Service (NRCS) considers all ofthese map
units to be non-hydric. Appling soils are mapped across the northern portion of the site. Appling
sandy loam is awell-drained, moderately permeable soil typically found on side slopes and

i
EcoScience Corporation
Mr. John Bove

Page2of5
rounded divides in Piedmont uplands. Faceville loamy sand is mapped in the southern portion of the
site. The Faceville series is a very deep, well-drained soil with moderate permeability. This series is
typically found on terraces along large streams.
Biological Features
The vegetation surrounding the site primarily consists of mixed pine/hardwood forest. On upper
slopes and ridges, the canopy contains northern red oak (Quercus rubra), white oak (Q. alba),
mockernut hickory (Carya tomentosa), pignut hickory (C. glabra), sweetgum (Liquidambar
styraciflua), loblolly pine (Pinus taeda), and tulip tree (Liriodendron tulipifera). Understory species
include flowering dogwood (Corpus florida), eastern red cedar (Juniperus virginiana), sourwood
(Oxydendron arboreum), black cherry (Prunus serotina), red maple (Ater rubrum), and red mulberry
(Morus rubra). Scattered vines and herbs include muscadine (Vitis rotundifolia), green-brier (Smilax
rotundifolia), and Japanese honeysuckle (Lonicera japonica). The lower portions adjacent to the
stream support species characteristic of a moist environment such as willow oak (Q. phellos),
American beech (Fagus grandifolia), ironwood (Carpinus caroliniana), hop hornbeam (Ostrya
virginiana), and American sycamore (Platanus occidentalis).
The site is expected to have moderate wildlife value as a result of the variation of on-site habitats and
adj acent development. The day of the site visit was cold and cloudy. No mammals were observed;
however, evidence of on-site mammals included tracks ofwhite-tailed deer (Odocoileus virginianus)
and raccoon (Procyon lotor). On-site bird observations include species characteristic of forest edges
and interiors such as northern mockingbird (Mimus polyglottos), blue jay (Cyanocitta cristata),
Carolina chickadee (Parus carolinensis), Carolina wren (Thryothorus ludovicianus), and American
robin (Turdus migratorius). No terrestrial reptiles or amphibians were identified.
urisdictional Area Determination
The U.S. Geological Survey (USGS) topographic quadrangle (Raleigh East, NC) indicates no
streams at the site. The county soil survey indicates an intermittent stream in the approximate area of
interest. Field surveys concluded that a perennial stream flows southward (from the northeast, east
of the access road) from a sediment basin through the culvert in the road bend (Figure 2). A buildup
of sediment (a delta) deposited by this stream has eliminated jurisdictional stream features for a
reach of approximately 90 feet upstream of the culvert. The stream reach reforms just above the
culvert. This stream has a confluence, approximately 60 feet below the culvert with an ephemeral
channel. The ephemeral channel flows southward (from the north, west of the access road) to this
confluence. The perennial stream is likely subject to Section 404/401 jurisdiction by the U.S. Army
Corps of Engineers (USAGE) and N.C. Division of Water Quality (NCDWQ). This stream is also

EcoScience Corporation
Mr. John Bove

likely subject to the Neuse River Riparian Buffer Rule. The ephemeral stream is not expected to be
subject to Section 404/401 jurisdiction or the Neuse River riparian buffer rule.
A vegetated seep wetland occurs south of the access road and west of the transfer station's gravel
parking lot. This vegetated wetland is oriented in a northeast to southwest direction and extends
approximately 75 feet to the confluence with the perennial stream. The wetland has an average
width of 40 feet, and is approximately 0.06 acre in size. This wetland is apparently a result of
seepage from underneath the gravel parking lot. Soils within this wetland were gray and contained
mottles and oxidized rhizospheres. Vegetation within this wetland has already been characterized
above. Additional wetlands and stream length occur downstream of those depicted by our
delineation, and additional stream length occurs upstream of our delineation. Additional field work
will be required to determine the type and extent of jurisdictional areas beyond the subject area of
interest.
The Neuse River riparian buffer rules are also an issue for this site. According to the rules, a 50-foot
vegetated buffer must be protected on each side of streams indicated on either USGS topographic
mapping or county soils mapping. The county soil survey map indicated a perennial stream west of
the transfer facility; therefore, the Neuse River riparian buffer rule is in effect fora 100-foot buffer
centered on the streams as approximately shown on the soils map.
Permit Issues
Two areas in the site are considered to be subj ect to jurisdictional consideration by the USACE and
NCDWQ: 1) the perennial stream located to the north and south of the culvert and 2) the vegetated
seep wetland south of the access road and west of the gravel parking lot. Impacts to either or both of
these areas will require authorization from USACE and NCDWQ, most likely through the
Nationwide Permit (NWP) process. NWP 14 applies to expansion or improvement of linear
transportation crossings. In this setting, this NWP can be used for a prof ect that does not exceed 0.5
acre of impact to waters of the United States (streams or wetlands). The USACE must be notified in
the form of a NWP application (Pre-Construction Notification [PCN]) if the project will impact 1)
greater than 0.1 acre of waters of the United States, 2) greater than 150 linear feet of stream
considered to be important by the USACE, or 3) any wetlands. If these thresholds are not exceeded,
no USACE notification is necessary. Any USACE notification for a NWP will need to include
mitigation for proposed impacts to streams and wetlands.
A NWP cannot authorize impacts to waters of the United States without an associated Water Quality
Certification from the NCDWQ. Use of a Water Quality Certification requires application to and
prior written concurrence from the NCDWQ.

EcoScience Corporation
Mr. John Bove
February 9, 2007
Page4of5
The NCDWQ will likely determine that the perennial stream is subject to the Neuse River riparian
buffer rule. Road crossings that impact 40 linear feet of riparian buffer or less are exempt from the
buffer rule. Road crossings that impact more than 40 linear feet and less than 1501inear feet or less
than 0.33 acre of riparian buffer may proceed providing there are no practicable alternatives to the
requested use. In this case, the applicant will need to obtain a determination of no practicable
alternatives through issuance of an Authorization Certificate from the NCDWQ.
Protected Species
The current U.S. Fish and Wildlife Service (USFWS) listing of federally protected species with
ranges which extend into Wake County includes four species: bald eagle (Haliaeetus
leucocephalus), red-cockaded woodpecker (Picoides borealis), dwarf wedgemussel (Alasmidonta
heterodon), and Michaux's sumac (Rhus michauxii). No suitable habitat occurs within the site for
bald eagle, red-cockaded woodpecker, and dwarf wedgemussel. Suitable habitat occurs for
Michaux's sumac on road shoulders within the area of interest. Surveys for this species typically
need to be conducted during the blooming season -May to October. This field effort occurred
outside of the survey window for this species; however, no specimens of any species of sumac were
observed during the site visit.
Summary
• The site is located in a developing industrial area east of Raleigh. Resources on the site are
not considered unique or significant.
• The site contains a perennial stream and jurisdictional wetlands subject to permit review by
the USACE and NCDWQ. Impacts to this stream can likely be authorized under USACE
NWP 14 (for linear transportation crossings). Use of this permit may not require notification
to the USACE but will require notification to the NCDWQ.
• County soils mapping indicates that an intermittent stream occurs in the site, raising the
likelihood that the NCDWQ will consider the Neuse River riparian buffer rule to be in effect
along this stream. Impacts to more than 40 linear feet of stream buffer will require
notification to the NCDWQ.
• Suitable habitat exists within the site for only one federally protected species - Michaux's
sumac. This field investigation occurred outside of the survey window for this species;
however, no sumac species were observed during the field investigation, so the proposed
project is not expected to result in an adverse impact to this species. Natural resource
agencies will have the right to request a survey for this species be conducted during the
designated survey window (May to October).
