Dear Ms. Marshburn:
This office has received a soil erosion and sediment control plan for the project listed above which
was submitted as required by the North Carolina Sedimentation Pollution Control Act (G.S_ 113A-57 (4))_ The
Act requires that all persons disturbing an area of one or more acres of land must obtain approval of a soil
erosion control plan prior to the commencement of the land -disturbing activity (G.S. 113A-54(d) (4)).
The review period for an express review is three days of receipt of a complete plan. If additional
information is requested, it must be submitted within five working days of receipt.
Commencement or continuation of a land -disturbing activity under the jurisdiction of this Act prior to
the approval of an erosion and sediment control plan is a violation of the Act.
We have performed a preliminary review of your submitted plan and have determined that additional
information will be necessary before a final review can be completed. Enclosed is a checklist of items that
must be submitted before we can complete the review process. Failure to provide the additional information
may result in disapproval of your plan.
The approval of an erosion and sediment control plan is conditioned on the applicant's compliance
with Federal and State water quality laws, regulations and rules.

1, The plan refers to a sediment trap (in a note); however, it is unclear where it is to be located_ If the Bio-
retention pond is to be used for sediment storage during the early construction phases, it must be installed
along with a collection system to divert it to that area shortly after work commences. It seems however,
that during a preliminary meeting on 5/30/06, Mr. Chiles indicated that he did not want to use the retention
area for sediment storage. Please clarify as it has been over a month since we met.
2. Provide design details/ dimensions and calculations for the sediment trap.
Please note: this additional information must be received no later than July 13, 2006. The express

EPRI Comments on the IEEE Standard for Safety Levels With Respect to
Human Exposure to Electromagnetic Fields, 0 to 3 kHz (2002)
The Institute of Electrical and Electronics Enlgincers (IEEE) recently published a standard for human
exposure to electric and magnetic fields in the frequency range of to 3 kilohertz (kHz). ' This standard was
developed over several rears by Subcommittee I II of the IEEE Standards Coordinating Committee 28 (SCC-
28), now known as the IEEE International Committee on Electromagnetic Safety (ICES).
The IEEE Standard is founded upon a careful examination of the current understanding of biological effects
of electrostimulation. The Standard explains the extrapolation from internal dose to external exposure and
characterizes the uncertainties associated with this process in detail. The resulting standard is a detailed and
complex document with discussions of neurophysiological processes.
Other organizations that have developed guidelines for electric and magnetic field exposures in this
frequency range are the American Conference of Governmental Industrial Hygienists (ACGIH), through its
Threshold Limit Values (TLVsOO): s the National Radiological Protection Board (NRPB) in the United
Kingdom;and the international Commission on Non -Ionizing Radiation Protection (1CN1RP), an affiliate
of the World Health Organization (WHO).''
Description of the Standard
General Approach
Scope
The IEEE Standard recommends limits on exposures to magnetic fields, electric fields, and contact currents
in the frequency ranee of to 3000 hertz (Hz). Exposure limits are derived for both controlled (occupational)
and uncontrolled (publicly accessible) environments: for uniform and nonuniform fields: for whole -body and
extremity exposures: and for pulsed fields and multiple -frequency exposures. This commentary does not
cover the last two factors.
The ICES states that the limits are intended to protect against the following adverse short-term effects:
• aversive or painful stimulation of sensory or motor neurons
• muscle excitation that may lead to injury while performing hazardous activities
• excitation of neurons or direct alteration of synaptic activity within the brain
• cardiac excitation
• adverse effects associated with induced potentials or forces on rapidly moving ions with the body.
such as blood flow
Potential chronic effects associated with long-term exposure are not considered, the ICES states, for two
reasons: (1) there is not sufficient reliable evidence that community or occupational exposures cause adverse
chronic effects, such as cancer_ and (2) there is no confirmed mechanism that would provide a basis for
predicting lone -term effects.
Basic Restrictions and Maximrmr Permissible Erpasures
For effects involving a known internal mechanism of field interaction, limits for acceptable exposures are
derived from a basic resiriction for an internal body dose below which no adverse effects occur in humans.
Given the basic restriction, physical and biological models are used to estimate exposure limits for external
Fields. Exposure limits, referred to in this standard as maximum (MPE) and in other
guidelines as reference levels. represent the field level below which the basic restriction will not be exceeded

ILsFF. Standard for liaposurc to Vectronragnelic Fieldv
Jar umy 2003
Page 2
However, exposures above the MPE may or may not cause the basic restriction to be exceeded. Thus, the
basic restriction is the ultimate determinant as to whether the standard is exceeded.
When an internal mechanism is not known or quantified for an effect. exposure limits are derived from
external field and current levels known to cause adverse reactions, as in the case of aversive spark discharges
during electric field exposure. In such cases, the MPE level is derived directly from data on empirical effects
and no basic restriction applies.
Adverse Effects and.Mechatfisrrrs
In establishing basic restrictions for electric and magnetic field exposures, the IEEE Standard assumes that
the in situ electric field is the fundamental electric parameter responsible for electrostimulation effects. This
assumption is based on a contemporary understanding of neurophysiological effects. It allows for a more
accurate derivation of MPE levels than does the previously relied -upon assumption that internal current
density is the relevant parameter. °
Magnetic field exposure limits are extrapolated from permissible in situ electric field doses using simple
elliptical induction models. Electric field and contact current limits are derived directly from data on sensory
responses to external fields and currents.
Threshold Multipliers
For both occupational and general -public exposures, conservative assumptions are employed to ensure that
limits are based on excitation thresholds below those of the vast majority (> 99 percent) of healthy adults. To
derive limits, threshold multipliers (sufeo,fiaclors) are applied to empirical data. These multipliers account
for overly sensitive individuals. including- children. and for uncertainties in both the determination of
adverse -effect thresholds and the extrapolation from internal dose quantities to external exposure levels. The
response thresholds used in deriving limits for the general public are generally lower than those for
controlled environments.
Magnetic Fields
Basic Resiricl ions
The IEEE Standard links the in sitrr electric field to effects in specific excitable tissues in the brain. heart, and
peripheral nerves. The basic restriction on the electric field in the body varies by anatomical location and
Frequency, and is different for individuals in controlled environments than for the general public. The effect
with the lowest exposure threshold for a given location in the body and a given frequency determines the
MPE level for that exposure.
For example. 60-1-Iz head and torso MPE levels are determined by the basic restriction derived from the
threshold for synaptic excitation in the brain; 60-1-fz MPE levels for limbs are determined by the basic
restriction for peripheral nerve (20-micrometer neuron) pain. Above 759 Hz. the MPE levels for the head and
torso are determined by the basic restriction for peripheral nerve stimulation in the torso. At very low
frequencies (< 0.153 Hz for head and torso; < 10.7 I-Iz for extremities), adverse effects associated with
induced potentials and forces on rapidly moving charges in the body determine MPE levels.
Maxinnrm Permissible Exposures
MPE levels for magnetic field exposures are given in Table i as a function of frequency. The whole -body
(head and torso) MPE level for uniform 60-1-1z magnetic fields in a controlled environment is 2.71 millitesla
(mT) or 27.1 gauss (G). For arms and legs, the occupational MPE level at 60 Hz increases to 63.2 mT
(632 G). Whole -body MPE levels for the general public are lower by a,factor of three than those for
controlled environments. Exposures above these levels require evaluation to determine compliance with the
basic restriction.

The IEEE Standard MPE levels are given in terms of uniform, single-phase fields over the body or a portion
of the body. For nonuniform fields, the standard specifies that the maximum field on the body is to be
compared with the MPE level. Most realistic maggnetic field exposures at fields near guideline levels are not
uniform. Comparing the highest measured field over the body with the M PE levels for uniform fields may be
overly conservative; that is, exposure in measured fields that exceed MPE limits may not exceed the basic
restriction. Evaluation of nonuniform magnetic field exposures can determine whether the basic restriction
on the in situ electric field is in fact exceeded for such exposures.'
Electric Fields
Basic Reslrlclloi7s
For electric Field exposure, the thresholds for sensing contact currents and spar: discharges and perceiving
the Field occur at much lower electric field levels than do the thresholds for direct electrostimulation. Thus,
the MPE levels for electric field exposures are determined by sensor), responses to external conditions rather
than by an internal response to induced electric fields.
The short-term effects that electric field limits seek to avoid are annoying field perception, painful spark
discharges. and aversive or painful contact currents. The currents and spark discharges can occur when an
ungrounded person standing in an electric field touches a conductive path to ground. Field perception is
enhanced when a person situated in an electric field is also well grounded.
Empirical data are available for the external conditions under which aversive shocks from spark discharges
and contact currents and annoying field perception take place. 6-7, 8 The WE levels for electric field
exposure at 60 Hz are derived directly from the external Field levels below which spark discharges are not
aversive. These conditions apply to a person standing upright in a uniform. vertical field. Above 282 Hz for
controlled environments. and above 368 Hz for general -public environments, the contact current MPE levels
are the basis for setting MPE levels for electric fields.
In controlled environments, spark discharges can be mitigated through the use of appropriate work clothing.
grounding.: measures, and other work practices. allowing the MPE level to be increased to 20 kilovolts per
meter (kV/m). At this level. however, Field perception is also a consideration: 50 percent of standing adults
perceive the field, and about 5 percent experience annoying sensations on the body caused by hair vibration.
The 20-kV/m limit can be exceeded in controlled environments if no Ground is within reach.

MPE levels for whole -body electric field exposure are given in Table 2 as a function of frequency. The MPE

Alonui#form Fields
The IEEE Standard MPE levels would apply directly to electric Feld exposures under transmission lines,
where the fields are uniform. However, in nonuniform fields on or near grounded structures, spatial
averaging over the body is used to determine whether the MPE level is exceeded.
Contact Currents
The IEEE Standard also establishes MPE levels for contact currents that occur when an individual touches a
grounded object when standing in an electric field. These limits are independent of frequency between 0 and
3000 Hz. The MPE levels for contact currents in controlled environments are 3 milliamperes (mA) and
1.5 mA for grasp and touch contacts, respectively. The MPE level for the general public is 0.5 mA for a
touch contact, (Grasp contacts do not apply to the general public.)
The contact current limits, and hence the electric field MPE levels, apply only to an ungrounded person
touching a grounded conductor, and may not protect a grounded person touching large conductive objects
that are insulated from ground. Limits on 60-Hz_ contact currents due to electric field induction on large
objects located under transmission lines are established in the National Electrical Safety Code (NESC). 9
EPRI Comments
Occupational Exposure
The 60-1-lz magnetic fields in certain power company work environments can on rare occasions exceed the
MPE levels and TLVs® cited in the IEEE; ACGIH, and 1CNIRP guidelines. 10' ii_i2 However, the generally
nonuniform nature of these magnetic fields makes the likelihood of noncompliance much less probable. 5 In a
nonuniform field, the in situ electric field may fall below the basic restriction after accounting for spatial
variation of the field over the entire body. The nonuniform fields associated with realistic exposures in power
company environments also make the exceedance of the more stringent basic restriction of
10 milliamperes per square meter (mA/ni) found in the ICNIRP guidelines unlikely.

IEEE Slandard.for Evpostu•e to Efeefromagrrelic Pields
Jamearl' 003
P(a e J
Exposures to electric fields in the electricity industry will generally be below the 1117EE Standard MPE level
of 20 kVlm. However. exposures for workers climbino towers near conductors at 500 kV or higher can result
in whole -body average fields above this level. In these cases, body orientation with respect to the field may
mitigate field perception and spark discharges relative to those experienced when standing in a vertical field.
For performing bare -hand maintenance on high -voltage transmission lines, work practices generally require
the wearing of hooded conducting suits and gloves as shielding.
Fields enhanced by corona -generated ions near high -voltage direct -current (I-IVDC) lines can sporadically
exceed 20 Min. i'' 14 The IEEE Standard specifies a minimum MPE level (based on the occurrence of spark
discharges) of 20 kV/m for electric fields below I Hz. Below 1 Hz the MPE level can be increased if the
leakage resistance to ground of an individual standing in the field mitigates spark discharges. This provision
would general],,, allow the high static electric fields found under HVDC transmission lines to comply with
the IEEE Standard.
General -Public Exposure
The magnetic fields in spaces accessible to the general public are very unlikely to exceed the 60-Hz WE
level of 0.9 mT (9 G) cited in the IEEE Standard. Similarly. static magnetic fields near power facilities are
very unlikely to exceed the static field limits established for the general public under this guideline.
The IEEE Standard explicitly increases the general -public MPE level for 60-Hzelectric fields from 5 kV/m
to 10 kV/m on transmission line rights -of -way. Exposure of the general public would not exceed the MPE of
10 Min'. except in limited areas under some 765-kV lines.
Public use of HVDC transmission line rights -of -way could result in exposures to static electric fields above
20 kV/m. However, realistic leakage resistances make it unlikely that such exposures would exceed an MPE
level based on potential spark discharges.
SummarN
The IEEE Standard represents a clear advancement in the development and documentation of exposure
guidelines in the designated frequency range. This advancement is accomplished by (I) assuming that the in
situ electric field is the principal physical parameter defining the interaction of fields with the human body:
(2) accounting for different interaction thresholds at specific locations in the body; (3) using the lowest
demonstrated internal or external field threshold for interaction as the determinant of MPEs: (4) explicitly
documenting the extrapolation from sensory responses such as field perception associated with external
electric field and current exposures to the electric field MPE levels: and (5) introducing empirically based
adjustments to thresholds to account for uncertainties.
Implementation of the IEEE Standard is expected io have minimal impact on current electric power company
practices. One possible exception is that the design of 765-kV lines might need to be changed to meet the 10-
kV/m limit for general -public exposure on rights -of -way. On the other hand. implementation of the ICNIRP
guidelines, which specify lower MPE levels for both occupational and general -public exposure. could have
an impact on transmission line design. work practices, and right-of-way management. 15
