PROJECT NARRATIVE
THE PROPOSED JAMES 44KV TRANSMISSION LINE PROJECT IS LOCATED IN BURKE COUNTY,
NORTH CAROLINA. THE PROJECT INCLUDES ASSOCIATED LINE WORK REQUIRED TO REBUILD
DUKE ENERGY'S JAMES 44KV TRANSMISSION LINE (LINE INDEX 4131277) BEGINNING AT
BRIDGEWATER HYDRO SUBSTATION (STA 1181), 5790 POWERHOUSE ROAD, MORGANTON, NC
AND ENDS AT TABLE ROCK TIE STATION (STA1 580),1138 CARBON CITY ROAD, MORGANTON, NC.
THE PROJECT IS LOCATED WITHIN DUKE ENERGY'S MOWED AND MAINTAINED RIGHT OF WAY.
THE DISTURBED AREA IS 45.80 ACRES. ALL PROPERTY EASEMENTS WILL BE ACQUIRED PRIOR
TO CONSTRUCTION ACTIVITIES, INCLUDING INSTALLATION OF EROSION CONTROL MEASURES.
THE PRIOR USE OF THE SITE IS TRANSMISSION INFRASTRUCTURE AND THE PROJECT WILL NOT
CHANGE THE EXISTING LAND USE. PRIOR TO CONSTRUCTION, A DUKE ENERGY CONSTRUCTION
CONTRACTOR WILL INSTALL EROSION CONTROL MEASURES TO ENCOMPASS THE ANTICIPATED
CONSTRUCTION LIMITS. PREDEVELOPMENT CONDITIONS WILL BE RESTORED, AND THE AREA
WILL BE STABILIZED PRIOR TO COMPLETION OF CONSTRUCTION. AN AVOIDANCE AND
MINIMIZATION OF DISTURBANCE APPROACH HAS BEEN INCORPORATED INTO THE DESIGN OF
THE EROSION CONTROL MEASURES BY UTILIZING EXISTING ACCESS POINTS AND STABILIZED
RIGHT-OF-WAY ACCESS ROUTES WHENEVER POSSIBLE. EROSION CONTROL MEASURES ARE
INDICATED HEREIN FOR PERMITTING USE ONLY BY NCDEQ. THE INITIAL PROJECT DURATION IS
ANTICIPATED TO START ON 03/29/2021 AND BE COMPLETED BY 08/13/2021.

firm, friable seedbed. A dish with blades set nearly straight can be used as a mulch anchoring tool.
PURPOSE
To reduce erosion and decrease sediment yield from disturbed areas, and permanently stabilize such
areas in a manner that is economical, adapts to site conditions, and allows selection of the most
appropriate plant materials.
SPECIFICATIONS
SEEDBED REQUIREMENTS
Establishment of vegetation should not be attempted on sites that are unsuitable due to excessive
soil compaction, inappropriate soil texture, poor drainage, concentrated overland flow, or steepness of
slope until measures have been taken to correct these problems.
To maintain a good stand of vegetation, the soil must meet certain minimum requirements as a
growth medium. The existing soil should have these criteria:
• Enough fine—grained (silt and clay) material to maintain adequate moisture and nutrient supply
(available water capacity of at least .05 inches water to 1 inch of soil).
• Sufficient pore space to permit root penetration.
• Sufficient depth of soil to provide an adequate root zone. the depth to rock or impermeable
layers such as hardpans should be 12 inches or more, expect on slopes steeper than 2:1 where
the addition of soil is not feasible.
• A favorable pH range for plan growth, usually 6.0 — 6.5.
• Free from large roots, branches, stones, large clods of earth, or trash of any kind. Clods and
stones may be left on slopes steeper than 3:1 if they are to be hydro seeded.
If any of the above criteria are not met — i.e., if existing soil is too coarse, dense, shallow or
acidic to foster vegetation — special amendments are required. the soil conditioners described below
may be beneficial or, preferably, top soil may be applied.
SEEDBED PREPARATION
Install necessary mechanical erosion and sedimentation control practices before seeding, and complete
grading according to the approved plan.
Lime and fertilizer needs should be determined by soil tests. Direction, sample cartons, and
information sheets are available through county Agricultural Extension offices. Testing is also done by
commercial laboratories.
When soil test results are not available, follow rates suggested in the seeding specifications shown at
right. Application rates usually fall into the following ranges.
• Ground agricultural limestone:
Light —textured, sandy soils: 1 to 1-1/2 tons/acre
Heavy —textured, clayey soils: 2 — 3 tons/acre
• Fertilizer:
Grasses: 800-1200 lb/acre of 10-10-10 (or the equivalent)
Grass —legume mixtures: 800-1200 lb/acre of 5-10-10 (or the equivalent)
Apply lime and fertilizer evenly and incorporate into the top 4-6 inches of soil by disking or other
suitable means. Operate machinery on the contour. When using a hydro seeder, apply lime and
fertilizer to a rough, loose surface.
Roughen surfaces prior to seeding.
Complete seedbed preparation by breaking up large clods and raking into a smooth, uniform surface
(slopes less than 3:1). Fill in or level depressions that can collect water. Broadcast seed into a
freshly loosened seedbed that has not been sealed by rainfall.
SEEDING
Seeding dates given in the seeding mixture specification are designated as "best" or "possible".
Seedings properly carried out within the "best" dates have a high probability of success. It is also
possible to have satisfactory establishment when seeding outside these dates. However, as you
deviate from them, the probability of failure increases rapidly. Seeding on the last date shown under
"possible" may reduce changes of success by 30-50%. Always take this into account in scheduling
land —disturbing activities.
Use certified seed for permanent seeding whenever possible.
Labeling of —non —certified seed is also required by law. Labels contain important information on seed
purity, germination, and presence of wood seeds. Seeds must meet State standards for content of
noxious weeds. Do not accept seed containing "prohibited" noxious weed seed.
When using a drill or cultipacker seeder, plant small grains no more than 1 inch deep, grasses and
legumes no more than 1 /2 inch. Equipment should be calibrated in the field for the desires seeding
rate.
When using broadcast —seeding methods, subdivide the area into workable sections and determine the
amount of seed needed for each section. Apply one—half the seed while moving back and forth
across the area, making a uniform pattern: then apply the second half in the some way, but moving
at right angles to the first pass.
Mulch all plantings immediately after seeding.
HYDRO SEEDING
surface roughening is particularly important when hydro seeding, as a roughened slope will provide
some natural coverage for lime, fertilizer, and seed. The surface should not be compacted or
smooth. Fine seedbed preparation is not necessary for hydro seeding operations: large clods, stones,
and irregularities provide cavities in which seeds can lodge.
Rate wood fiber (cellulose) application should be at least 2,000 lb/acre.
Apply legume inoculants at four times the recommended rate when adding inoculant to a hydro
seeder slurry.
If a machinery breakdown of 1 /2 to 2 hours occurs, add 50% more seed to the tank, based on the
proportion of the slurry remaining. This should compensate for damage seed. Beyond 2 hours, a full
rate of new seed may be necessary.
Lime is not normally applied with a hydraulic seeder because it is abrasive. It can be blown onto
steep slopes in dry form.
MAINTENANCE
Generally, a stand of vegetation cannot be determined to by fully established until soil cover has
been maintained for one full year from planting. Inspect seeded areas for failure and make necessary
repairs and reseedings within the same season, if possible.
Reseeding --If a stand has inadequate cover, re—evaluate choice of plant materials and quantities of
lime and fertilizer. Re—establish the stand after seedbed preparation or over —seed the stand.
Consider seeding temporary, annual species if the time of year is not appropriate for permanent
seeding.
If vegetation fails to grow, soil must be tested to determine if acidity or nutrient imbalance is
responsible.
Fertilization --On the typical disturbed site, full establishment usually requires re —fertilization in the
second growing season. Fine turf requires annual maintenance fertilization. Use soil tests if possible
or follow the guidelines given for the specific seeding mixture.

Narrative
Duke Energy has plans to rebuild a 44kV transmission line from an existing power plant off
Powerhouse Road, Morganton, NC to an existing substation off Carbon City Road, Morganton,
NC in Burke County. Multiple access points will be required along the route due to topographic
challenges, road crossings, and property obstructions. Access points will be necessary for
maintenance and construction of poles, towers, and lines. The construction of these access roads
will require the installation of a culvert across a tributary (S8) to the Catawba River (S9). The
location of the culvert will be 1500 feet northwest of construction entrance 12 on the Private Road
stemming from Pollard Avenue.
The drainage area for the culvert location is approximately 43.09 acres as shown on the Drainage
Area Map in Appendix A. After assessing the existing conditions, including the topography, Soil
Map and Report (Appendix B), Curve Numbers (Appendix C), and rainfall data (Appendix D), a
60" reinforced concrete culvert was determined appropriate to adequately convey a 25-yr rain
event and pass the existing tributary flow.
The 25-yr storm was calculated at 93.00 cfs using the SCS Type II 24 hour storm event method.
The two types of soils present on the site are categorized as hydrologic soil group B.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/
portal/nres/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https:Hoffices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil
Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/?
cid=nres142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NRCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.
The U.S. Department of Agriculture (USDA) prohibits discrimination in all its
programs and activities on the basis of race, color, national origin, age, disability,
and where applicable, sex, marital status, familial status, parental status, religion,
sexual orientation, genetic information, political beliefs, reprisal, or because all or a
part of an individual's income is derived from any public assistance program. (Not
all prohibited bases apply to all programs.) Persons with disabilities who require

alternative means for communication of program information (Braille, large print,
audiotape, etc.) should contact USDA's TARGET Center at [phone] (voice
and TDD). To file a complaint of discrimination, write to USDA, Director, Office of
Civil Rights, 1400 Independence Avenue, S.W., Washington, D.C. 20250-9410 or

The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, along
with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus, the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each. A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions, especially where the pattern was so complex that it
was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landforms or

landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, however,
onsite investigation is needed to define and locate the soils and miscellaneous
areas.
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity, degree of erosion, and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series. The name of a soil phase
commonly indicates a feature that affects use or management. For example, Alpha
silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar. Alpha -Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform. An area can
be made up of only one of the major soils or miscellaneous areas, or it can be made
up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.
