Summarize the results of soil, groundwater, surface water assessment and free product measurement,
indicating the nature and extent of contamination, the estimated rate of migration, and potential for
impacting receptors:
Laboratory analysis of soil samples reported total petroleum hydrocarbons-diesel range organics (TPHono) at a
maximum concentration of 73 milligrams per kilogram (mg/kg) in shallow soils in the Former AST Area.
Laboratory analysis of soil samples reported TPHono at a maximum concentration of 1,400 mg/kg in shallow
soils in the Surface Spill Area. Laboratory analysis of a groundwater sample (Phase ll ESA) collected in the
Former AST Area reported a naphthalene concentration of 9.4 micrograms per liter (pg/L); laboratory analysis of
a groundwater sample (Phase ll ESA) collected in the Surface Spill Area reported a 1,1-dichloroethane
concentration of 8.4 pg/L. Miscellaneous other semi-volatile organics for which there are no applicable
regulatory standard were reported in groundwater samples collected in both areas.
Only limited groundwater assessment has been performed in the two areas due to the impending dernolition of
the onsite buildings in preparation for site sale and redevelopment; additional groundwater assessment will be
performed once dernolition efforts are complete. A separale conective action plan will then be prepared to
address groundwater impact, if necessary.
lndicate the risk classification (or non-UST petroleum/non-petroleum UST rank) and the criteria for that
determinationr
The site has been assigned a "High" risk ranking by NC DENR, because shallow soils in both areas contain
elevated TPDono concentrations (i.e., greater than 40 mg/kg) and there are active potable wells within a 1,000-
foot radius of the site. The concentration (9.4 trg/L) of naphthalene in groundwater in the fuel oil Former AST
Area exceeds the NC 2L Standard of 6.0 pg/L, The 1,1-dichloroelhane concentration of 8.4 pg/L reported
during the Phase ll ESA in the Surface Spill Area is assumed to be associated with the volatile organic
compound (VOC) plume located along the rear of the main plant building; this VOC release is unrelated to the
areas under discussion herein and is being managed by the lnactive Hazardous Sites Branch.
lndicate the soil, groundwater, and sudace water concentration levels to which contamination must be
remediated:
Soil in the two areas must be remediated to less than the Soil-toGroundwater Maximum Soil Contaminant
Concentrations (MSCCs). Groundwater impaded by releases from the two areas will require remediation to the
2L Standards; this will be addressed in a separate document, if required, based on further groundwater
assessment. Surface water has not been sampled but is not suspected to be impacted based upon the
apparent limited extent of groundwater impact as a result of the two releases.
Present the selecied remedy for soil and groundwater contamination and/or actions to reduce the risk
classification (or rank) and briefly state the basis for selection, schedule for implementation,
remediation milestones, and cost:
Excavation and removal with offsite disposal has been selected as the most appropriate soil remedy based
upon the relative cost, ease of implernentability, and both short- and long-term effectiveness. The total cost to
excavate and remove impacted soil in the Former AST and Surface Spill Areas is estimated to be approximately
$15,000. Soil rernoval is planned subsequent to dernolition of the onsite structures which is expected to be
completed in April 2013; it is anticipated that soil rernoval can be completed in approximately one to two weeks.

the hydraulic oil ASTs. A run of 3/&inch diamder piping for the fuel oil AST ran from the AST directly to the
humidity steam unit machine. Each hydraulic oil AST was integrated into a separate mold press machine.
These tanks have all been removed from the site as part of site decommissioning adivities. The incident
number for the site is 95191 .
Provide information about petroleum AST systems, petroteum spills, and other non-UST petroleum
releases:
The locations of the former fuel oil AST and the hydraulic oil ASTs are depicted on Figure 2. Specific details
related to the ASTs are presented in Table B-2: Site Histry- ASf System and Other Release lnformation.
Provide a comprehensive description of the release:
A Phase ll Environmental Site Assessment (ESA) was performed at the site in October 2011 by synTara. Two
separate areas, a former fuel oil AST (Former AST Area) and an apparent surface spill location (hydraulic oil
ASTs associated with machinery, also referred to herein as "Surface Spill Area") were identified by synTerra in
the Phase ll ESA report as having a "potential for contamination to be present" based on either historical
operations or the presence of surface staining. Soil and groundwater sampling in these two areas during the
Phase ll ESA indicated a release. The estimated quantity and cause of release in each of these two areas is
unknown.

5. Provide a brief description of site characteristics:
The site use was formaly utilized by lnternational Resistive Company for industrial purposes but that prooess
has been permanently discontinued and the facility is currently being decommissioned in preparation for
demolition and site redevelopment. Property to the north is used as commercial retail and residential. Proprty
to the east is used as residential. Property to the south is mostly vacant and wooded with some sparse
residential development. Property to the west is used for commercial purposes.
The site is mostly level, similar to property to the north, east, and west. Property to the southeast and
southwest is situated at a higher elevation than the site. Property directly south of the site is significantly higher
over a sho( distance (steep slope).
The southern and southwestern portions of the site are covered with hardwood trees. The eastern and western
portions of the site are covered with grass.
A spring originates on the steep slope south of the site and flows onto the site where it enters a culvert. This
spring flows through the culve( beneath the southern portion of the plant towards the east where it enters a
storm drain box and turns north where it rqnains in a culvert until it flows beneath Greenway Drive and a
residential lot where it flows into a stream bed. A second spring originates from property southeast of the site
and flows into a culvert on the site and enters the storm drain box discussed above.
Two water supply wells are located on the site: DW-1 east of the plant and DW-2 south of the plant. The two
wells are located greater than 250 feet from the Former AST Area and the Surface Spill Area. The wells
formerly supplied water for use in plant operations and were not used as sources of drinking water. Drinking
water for the site was provided by the Town of Boone municipal water system. Municipal water is available in
the area and is used by surrounding commercial properties and residential properties. There are nine
monitoring wells currenfly located on the site that are used to monitor a VOC plume located on the south side of
the plant; this release is being managed by the lnactive Hazardous Sites Branch and is unrelated to the two
areas under discussion herein.
Surface cover north and east of the plant is asphalt; south and west of the plant is grass. The soil type is mainly
sandy clayey silt and sifiy sand. Depth to and nature of bedrock is unknown. Depth to groundwater ranges
from three to eleven feet below ground surface based on existing monitoring wells and soil/groundwater
assessment activities. Based on the groundwater depths measured in the monitoring wells discussed above,
groundwater flow is to the east-northeast across the site.

E. SUMMARY OF SITE ASSESSMENT INFORMATION
1. Summarize site assessment information and any pre-CAP monitoring:
Groundwater was en@untered at a depth of approximately 10 feet below ground surface in the Former AST
Area and at an approximate depth oI 12 l*l in the Surface Spill Area. Laboratory analysis of soil samples
reported TPHono at a maximum concentration of 73 mg/kg in shallow soils in the Former AST Area. Laboratory
analysis of soil samples reported TPHono at a maximum concentration of 1,400 mg/kg in shallow soils in the
Surface Spill Area. As part of the Phase ll ESA, laboratory analysis of a groundwater sample collected in the
Former AST Area reported a naphthalene concentration of 9.4 pg/L; laboratory analysis of a groundwater
sample collected in the Surface Spill Area reported a 1,1-dichloroethane ooncentration of 8.4 pg/L.
Miscellaneous other semi-volatile organics for which there are no applicable regulatory standard were reported
in groundwater samples collected in both areas. Soil assessment data are presented in Table B-3: Summaty of
Soil Sampling Resu/fs.

2. Describe the geology/hydrogeology of the region and the site:
The site owner has closed plant operations and plans to denrolish the onsite buildings within the next six
months. Therefore, permanent monitoring wells were not installed during the CSA. Should monitoring wells be
needed in these areas, they will be installed onoe denrolition activities are complete. The locations of borings
installed in these two areas during the CSA were surveyed by a NC licensed surveyor to ensure the boring
locations can be located once dernolition is complete.
The site lies within the Blue Ridge Geologic Province of North Carolina. Geology in the area of Boone is
generally comprised of massive to well foliated biotite granitic gneiss (Geologic Map of Noilh Carclina;
Department of Natural Resources and Community Dwelopment, 1985). Generally rocks are strongily foliated
and fradured. The percolation of water downward through the fradures has resulted in the formation of a layer
of residual weathered material (saprolite) and soil at the land surface. The saprolite and residual soils typically
have high porosities but low hydraulic condudivities; thus, they do not readily transmit groundwater. The
saprolite and residuum are considered leaky (semi-pemeable) beds which may store and rechargewater to the
undollng bedrock aquifer. Groundwater occurs within the saprolite and residuum between the clay, silt, and
sand grains. Groundwater also occurs and flows within the bedrock along secondary features, joints, and
planes of weakness. The movernent of groundwater through the saprolite is strongly influenced by topography.
Groundwater within the Blue Ridge generally moves from topographically high areas (recharge zones) to
topographically low areas with and along stream valleys (discharge areas). The site is situated adjacent to a
steep mountain slope to the south. To the north, east, and west, the topography is generally flat. Soils in these
areas may be alluvial deposits.
Generally, soils encountered in the Former AST Area consist of a dark brown organic topsoil to a depth of 0.5
feet. A light brown fine sandy silt was encountered from 0.5 feet to six feet. A light brown sligtttly clayey silt
was encountered from a depth of six feet to eight feet. A light brown line sandy silt was encountered forn a
depth of eight feet to 10 feet down to the termination of soil sampling.
Generally, soils encountered in the Surface Spill Area consisted of a dark brown organic topsoil to a depth of 0.5
foot. A tan, finetocoarse sand was enountered from 0.5 feet to six feet in boring SSA-1 . A dark gray silty day
and sandy day silt was en@untered below the topsoil in borings SSA-2 through SSA-4. An orange-brorn fine
sandy silt was en@untered below the dark gray silty clay. Refusal to direct push technoloSy (DPT) equipment
was en@untered at 15 feet in SSA-1 and 14.5 feet in SSA-3.
Depth to groundwder at the site ranges from three to 11 feet below ground surface based on measurements
obtained from site monitoring wells (associated with a difierent release, managed by the IHSB) and limited
groundwater assessment performed during the CSA. Based on water lervel measurernents in the above
monitoring wells, groundwater flow has historically been documented as occurring to the east-northeast across
the site.

1.
Limited groundwater assessment performed in the two areas has indicated that groundwater is either not
impacied by the release (Surface Spill Area) or is only slightly impacted (Former AST Area). Based upon the
apparent limited extent of soil and groundwater impad, it is considered unlikely that a groundwater contaminant
plume originating from these areas would migrate offsite.
Examine and evaluate assessment information:
Laboratory analysis of soil samples reported TPHono at a maximum concentration of 73 mg/kg in shalloar soils
in the Former AST Area. Laboatory analysis of soil samples reported TPHono at a maximum concentration of
1,400 mg/kg in shallow soils in the Surface Spill Area. The area of soil impact in the Former AST Area is
estimated to be approximately ten feet by six feet, extending to an approximate estimated depth of three to four
feet below ground surface. The area of soil impact in the Surface Spill Area is estimated to be approximately
ten feet by five feet, extending to an approximate estimated depth of four feet bdow ground surface.
Laboratory analysis of a groundwater sample (Phase ll ESA) collected in the Former AST Area reported a
naphthalene concentration of 9.4 pg/L; laboratory analysis of a groundwater sample (Phase ll ESA) colleded in
the Surface Spill Area reported a 1,1-dichloroethane concentration of 8.4 pg/L. Miscellaneous other serni-
volatile organics for which there are no applicable regulatory standard were reported in groundwate samples
collected in both areas. Only limited grcundwater assessment has been performed in the two areas due to the
impending demolition of the onsite buildings in preparation for site sale and redevelopment; additional
groundwater assessment will be performed after dernolition efforts are complete.
The site is dassified as High Risk. Therefore, the applicable soil cleanup levels are the Soil-toGround'water
Maximum Soil Contaminant Concentrations (MSCCs). Groundwater deanup levels for the site (if applicable, to
be determined following additional assessment) are the NC Groundwater Quality Standards (i.e., NCAC 2L
Standards).
As mentioned above, the apparent extent of contamination in these areas, both to soil and groundwater, is
limited. These areas are also both located near the center of the property. These characteristics indicate a low
potential for contaminant migration ofisite or impact to receptors.
The site risk ranking could be lowered by remediation of impacted soil and groundwater (if applicable).
OBJECTIVES OF CORRECTIVE ACTION AT THE SITE

2. State purpose and objectives of the CAP:
The purpose of this CAP is to reduce the concentrations of petroleum hydrocarbons in soil. This document !g
not intended to address groundwater impact, if any, in the two areas under review; any potential groundwater
remediation will be addressed in a separate document, if necessary, following additional groundwater
assessment.
3. State the cleanup goals of the CAP:
The soil cleanup goals are the Soil-toGroundwater MSCCs, as discussed in Section E.3.
G. COMPREHENSIVE EVALUATION OF REMEDIAL ACTIONS
1. Present and comprehensively evaluate remedial ofiions:
Remedial Option Evaluation
a. Evaluate risk reduction mechanisms:
Not Applicable - The site risk ranking cannot be reduced solely by supplying an alternative drinking water
source to water supply well users.
b. Evaluate excavation as sole remedial process for soil contamination:
Soil remediation by excavation is a viable remedial option for the two Areas. This alternative o<hibits both
short and long-term effectiveness; is readily implementable; is ost-effective based on the apparent
shallow nature and relatively small volume of impacted soil to be removed; is protective of human helth
and the environment; and, is expected to garner NC DENR acceptance.
c. Evaluate natural attenuation as the sole remedial process for groundwater contamination:
Not Applicable - Groundwater assessment is not complete and any potential groundwater rernediation
which may be required will be discussed in a separate document.
d. Evaluate a minimum of two viable technology-based remedial options for soil and groundwater:
Soil
Soil Vapor Extraction - Soil vapor extradion (SVE) is an in situ unsaturated (vadose) zone soil
remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and
remove volatile and some senri-volatile contaminants from the soil. The gas leaving the soil may be
treated to recover or destroy the contaminants, depending on local and state air discharge regulations.
Vertical extraction vents are typically used at depths of five feet or greate and have been succesfully
applied as deep as 300 feet. Horizontal extraction vents (installed in trenches or horizontal borings) can
be used as warranted by contaminant zone geometry, drill rig access, or other sitespecificfadors.
For the soil surface, geomembrane @vers are oten placed over soil surface to prevent short circuiting
and to increase the radius of influence of the wells.

Low Permeability Capping - Hard-surface capping works by maintaining a high-strength, low-permeability
cover over the contaminated area to stabilize surface soil and reduce infiltration of surface water. The low-
permeability layer can be made from either asphalt or concrete. Asphalt usually is selected in favor of
concrete because the bitumen binder in asphalt provides some flexibility, making the oover more resistant
to cracks that tend to form as a result of temperature cycling and/or differential settlement. A top coat of
bitumen or rubberized-bitumen mastic may be applied to further decrease permeability.
For a cap applied in a high-traffic area, gravel may be mixed with the mastic to provide a wear resistant
surface. The lovv-permeability layer typically is placed on a high-permeability foundation laye. The
foundation helps reduce the negative effects of differential settling and allows drainage. Drainage under
the low-permeability layer is needed to prs/ent ponding of small amounts of water that may leak throqgh
the low-permeability layer or migrate upward from the soil. Ponded water can freeze and o<pand durirq
cold weather, causing frost heave damage to the cover.
lf gas generation in the waste volume must be controlled, a permeable vent layer can be plaoed on the
surface as the first layer of the cap. Vapor extraction by applying a vacuum to the vent layer at points
along the edge of the cap allows collection of gas for treatment.
Materials and mdhods used to place a hard-surface cap are similar to conventional road paving, but
indude modifications to reduce permeability and increase durability of the paving that forms the low-
permeability element. For example, an asphalt layer used for capping consists of bitumen mixed with fine
and coarse aggregate to give a specified well-graded aggregate mix as in paving. However, an asphalt
paving mixture used for capping will require a more tightly controlled particle size distribution and a higher
bitumen oontent in comparison to a standard road paving mi*ure.
Groundwater
Not Applicable - See above
For each option evaluated above:
1) Gonsideration of the nature and extent of the contamination at the site:
Surface Soill Area - Soil in this area is impacted by petroleum hydrocarbons from a hydraulic oil
release. The extent of soil impact is estimated to consist of an area measuring approximately five
feet by ten feet, o<tending from surface (or near surface) to a depth of approximately four feet
below ground surface. The surface of this area is grassed so contaminants are oeosed to the
environment.
Fonner AST Area - Soil in this area is impacted by petroleum hydrocarbons from a fud oil release.
The extent of soil impact is estimated to consist of an area measuring approximatdy six fed by ten
feet, extending from surface (or near surface) to a depth of approximately four feet below ground
surface. The surface of this area is grassed so ontaminants are exposed to the environment.

Description of each remedia! technology, mechanism, or process:
Excavation - This remedy consists of the removal of impacted material from the site and
transportation to a permitted offsite treatment and/or disposal facility; in this case, the material will
be managed as a non-hazardous waste with disposal likely in a municipal solid waste (Subtitle D)
landfill (waste characterization sampling will likely be required by the landfill prior to its acceptance
of the material). The volume of soil to be removed will initially be predetermined based upon data
generated during the CSA. Performance objectives will be quantified by the collection and analysis
of confirmation samples. lf confirmation sampling indicates that additional soil is present above the
remedial objectives, a second round of soil excavation will be performed and additional vermcafun
samples collected. Once perfonnance objectives have been achieved the excavation will be
backfill with uncontaminated soil that is imported from an offsite source. No permitting is
anticipated in conjundion with this alternative. Because this ranedy involves the rmtoval of
impacted material, there are no operation and maintenance oosts.
Low Permeabilitv Cappino - See previous subsection for description of this technology. For
application at this site, a small volume of impacted soil would likely require removal in order to
properly install the cap; this material would be managed as a non-hazardous waste, as described in
the previous alternative. No permitting is anticipated in conjunction with this alternative. Because
this ranedy does not involve treatment and/or removal of the impacted soil, the cap must be
maintained in perpetuity or until site conditions allow otherwise. Caps must be routinely
maintenanced and inspected to insure the integrity of the system is maintained.
Soil Vaoor Extraction - See previous subsection for description of this technology. For application
at this site, it is anticipated that one to two vertical soil vapor extradion (SVE) wells tttould be
installed in or just outside of the impacted area. ln order to for this alternative to funcdion
effectively, it would likely need to be installed in conjunction with a low permeability geomernbrane
cover to prevent short-circuiting of the air flow. A relatively small volume of impacted soil would
require rernoval and management as a non-hazardous waste, as previously described, in order to
install the cover and the vapor extraction well(s). A permit to construct and openate the SVE
systenr would be required; this would include obtaining a permit (or a permit waiver) fom the NC
DENR Division of Air Quality. Routine opaation and maintenance of the SVE systern uould be
required to insure optimum performance.
Discussion of feasibility and effectlveness of each remedial technology, mechanigrn, or
process:
Excavation - Excavation with offsite disposal is a commonly employed remedy at similar sites. lt is
readily implementable with common construdion equipment, does not require specialized
technology and/or knowledge, and is effective at permanently reducing the risk to human health
and the environment. lt is anticipated that contaminated soil from this site can be managed as a

non-hazardous waste; therefore, there are a number of proximate treatment and/or disposal
facilities that are permitted to accept impacted soil from this site. There are no operation and
maintenance (O&M) costs associated with this ranedy.
Low Permeabilitv Caooinq - A low permeability cap can be installed using common construction
practices and equipment. Although capping is effective at reducing the potential for leaching to
groundwater and for preventing direct human contact through dermal exposure, it is not effeclive at
reducing the concentration of site contaminants when used as a standalone remedy. Caps and
cap integrity must be maintained long term; therefore, land use restrictions must be employed in
conjunction with a cap. Land use restrictions associated with a cap may impact site rede\relopment
options.
Soil Vaoor Extraction - An SVE systern can be installed with commonly available drilling rigs and
construction equipment. ln most cases, the vacuum extraction pump and other syatent
@mponents are readily available from a number of suppliers. SVE is effective at reducing
conlaminant concentrations in situ through either volatilization or biodegradation. Because surface
and shallow soils at this site are impacted, SVE would require mupling with another technique such
as excavation with the installation of a low permeability geomembrane @ver. ln order to properly
design an SVE systern for a given site, a pilot test is often required. As mentioned praniously, SVE
systerns require regular O&M in order to insure proper operation.
4) Remedial system operation and maintenance plan for each remedial option:
Excavation -There is no O&M schedule associated Wth this remedy.
Low Permeabilitv Caooinq - O&M for a low permeability cap typically includes, at a minimum, an
annual inspection by a qualified person to assqss the condition of the cap and the need for repair
and/or maintenance. Maintenance activities may include re-sealing of the material, repair of
cracks, and/or removal of nearby deep-rooted vegetation (sudt as trees).
Soil Vaoor Extraction - Regular O&M is essential for the proper performance of an SVE systern.
lnitially, it is usually recommended that O&M visits be made by a trained professional on a weekly
basis. This schedule can be reduced to monthly or even quartaly, especially if telerndry is
integrated into the systern. Periodic site visits will continue to be made throughout the operational
life of the systern, however, for routine tasks such as changing filters and belts, adjusting flowrates,
and replacing offgas treatment units and/or disposing of accumulated water. Once ontaminant
rernoval rates have reached an asymptotic level, system operation may be reduced from full-time to
intermittent (or pulsed) to reduce operational costs.

Waste treatmenUdisposal plan for each remedial option:
Excavation - As previously discussed, it is anticipated that contaminated soil from this site may be
managed as a non-hazardous waste with disposal at a Subtitle D landfill. The total volume of soil
to be disposed from both areas is estimated to be approximately 25 tons.
Low Permeabilitv Caooinq - See above for management of impacted soil generated during cap
installation; the total volume of soil to be disposed from both areas is estimated to be less than one
ton. No other wastes are anticipated with this alternative.
Soil Vaoor Extraction - See above for management of impac'ted soil generated during system
installation. The total volume of contaminated soil from this site that would require clisposal is
estimated to be less than one ton. lf off-gas treatment is required, it would likely consist of
treatment via granular activated carbon (GAC); as the GAC units are expended (i.e., 'spent") they
would be replaced with nerrtr units and returned to the manufadurer for regeneration, likely on a
semiannual to annual basis. lt may also be necessary to periodically manage accumulated water;
this material would require charaderization prior to treatment and disposal, however, at this site it
would be anticipated to be managed as a non-hazardous waste. The volume of water to be
managed as a result of SVE operation is estimated to be approimately 100-200 gallons per year.
Monitoring ptan for each remedial option:
Excavation - Monitoring is not required for this alternative.
Low Permeabilitv Caooino - Monitoring in the form of visual assessment would be performed on an
annual basis.
Soil Vapor Extraction - Monitoring of the SVE influent and effluent (post treatment, if applicable)
would be performed on a periodic basis (assumed quarterly once systern has undergone
startup/shakedown phase) using an Organic Vapor Analyzer (OVA), Toxic Vapor Analper (TVA),
or similar field screening dwice. Once per year, an influent sample would be collected for
laboratory analysis using Method TO-15 (i.e., volatile organics). Monitoring results would be
summarized in an annual monitoring report to be submitted to the NCDENR. Once influent
concentrations reach asymptotic levels, soil borings may be advanced into the impaded zone to
collect soil quality data; soil samples will be analyzed for VOCs and/or SVOCs using EPA Mdhods
82608 and 827OC, respectively (or approved equivalent methods).

7) Comprehensive, well-substantiated schedule for each remedial option:
As previously discussed, IRC plans to denrolish the onsite structures in order to prepare the site for
redevelopment. Therefore, due to the proximity of the two areas under discussion herein to the
main plant building, implenrentation of this CAP will not begin until demolition activities are
complete. With that fundamental understanding, the following approximate schedules are
discussed below and are presented in Table 1.
Excavation - Soil excavation is anticipated to take one to two days to oomplete. Confirmation
sampling will be expedited so that supplernental excavation efforts may be undertaken if
necessary. Once the confirmation sampling results indicate that the remedial objec{ives have been
satisfied, the excavations will be bacKilled with offsite material. lmpacted soil will be te-mporarily
stored onsite until laboratory data indicate that rernedial objectives are achieved. The entire
process is expected to take approximately two to three weeks.
Low Permeabilitv Caooino - Preparation of the cap areas is expected to take one day. lnstallation
of the cap can begin the following day and is expected to take one to two dap to cornplde. As
previously discussed, monitoring in the form of visual assessment will be performed on an annual
basis.
Soil Vaoor Extraction - lt is anticipated that permitting for an SVE systern muld be complded by
the time facility dernolition is complete. The SVE system(s) would be constructed and housed in a
prefabricated building which would be delivered and setup onsite; once an order is placed for a
system, it is expected to take approximately six weeks for delivery; during that time, the SVE wells,
low permeability geomembrane cover, and extradion piping would be installed. Once the system
anives onsite, it can be hooked up to the SVE wells in one to two days. Scheduling and completion
of systan inspection by the municipality and other parties (e.9., electrical provider) is o<pected to
take approximately one week. System startup/shakedown and performance optimization is
anticipated to take approximately two to four weeks. O&M adivities will occur on a quarterly basis,
or more frequently, if wananted. Monitoring of the system influent (and effluent, as necessary) will
be peformed at least one per quarter. Annual reports summary system run time, influenUeffluent
concentrations, maintenance issues, and other related adivities will be submitted to the NC DENR
for review. Once influent concentrations have reached asymptotic levels, soil samples will be
collected for laboratory analysis to verify that remedial objectives have been achisred. lt is
anticipated that active SVE treatment will be required for a period of one to two years. Once
remedial objectivs have been achieved, the SVE systern will be dismantled and rernoved from the
site. All SVE wells will be permanently abandoned in accordance with NC well regulations.

o Performance verification sampling, final reporting, & systenr decommissioning - $6,000
o Estimated total - $94,000
2. Select best remedial option and discuss the basis for the selection:
Excavation with offsite disposal is selec'ted as the preferred soil ranedy for the site. This alternative is
selected based upon: the ease of implernentability; the short and long-term effectiveness in reducing site
contaminants of concern; overall protection of human health and the environment; and, the rdative cost. I.lo
permits are required for this rernedial alternative.

o A minimum horizontal and vertical clearance distance of 10 feet must be maintained
between the drill rig and overhead power lines; use spotters to help rig operator maneuver
the vehicle when near overhead power lines.
Other physical hazards which may be present on this project site include:
Back injuries due to improper lifting - Use proper lifting techniques. Lift with the legs, not
the back. Keep loads close to the body and avoid twisting. Loads heavier than 50
pounds (lbs) require a second person or mechanical device for lifting. Use mechanical
devices such as drum dollies, hand trucks, and tool hoists (for lifting augers) to lift or
move heavy loads whenever possible.
Ergonomic Stress - Lift carefully with load close to body with the legs taking most of the
weight. Get help with lifts greater than 40 lbs. When working with a heavy tool or object,
keep legs under the load and do not overreach or twist to the side. Reposition body to
be more square to the load and work. Push loads, rather than pull, whenever feasible.
Do not persist with lifting when the load is too heavy. Use a mechanical lifting aid or
have a coworker assist with the lift. Rotate repetitMe tasks to avoid soft-tissue fatigue.
Falls From Elevated Surfaces - Protect employees from falling off surfaces that have a
side or an edge that is 6 ft or more above a lower level. Provide a safety harness and
shock-absorbing lifeline or adequate fall protection where applicable. Employees must
wear them when woking 6 ft or higher above the platform or main work deck. lnstall
either a guardrail system or fall arrest system that conforms to 29 CFR 1926.502 (d) and
is approved by the American National Standards lnstitute.
Fire and Explosion - Make ABC fire extinguishers accessible in the work area. Store
flammables in Underwrite/s Laboratory and Occupational Safety and Health
Administration (OSHA) approved metal safety cans equipped with spark arrestors. Store
flammable containers more than 50 ft from possible ignition sources. Keep exhaust
equipment powered by internal combustion engines well away from flammables and
combustibles. Secure hot work permits/approvals before welding or cutting. Store and
use compressed gases in a safe manner. Never refuel equipment (e.9., genenators)
while it is in operation or hot enough to ignite fuel vapors. Conspicuously mark
operations that pose fire hazards "No Smoking' or "Open Flames." Remove trash,
weeds, and unnecessary combustibles from the Exclusion Zone (EZ). Transfer of
potentially flammable liquids will be conducted with intrinsically safe pumping equipment.
Drums will be bonded and grounded prio_r to transfer of potentially flammable liquids.
Vehicles - Obey all site traffic signs and speed limits. Seat belts must be functional and
in use during operation of any site vehicles (including rentals). Operator shall regularly
inspect the vehicle for defective parts, such as brakes, controls, motor, chassis and
drives. Always be aware and stay alert to traffic around the work area.
lnclement Weather - The project may be shutdown by the SSO during the following
inclement weather conditions: poor visibility; precipitation severe enough to impair safe
movement or travel; lightning in the immediate area; steady winds in excess of 40 mph;

or, other conditions as determined by the SSO or Corporate Safety and Health Manager.
Work will resume when the conditions are deemed safe by the SSO.
. Noise - Wear hearing protection when speech becomes difficult to understand at a
distance of 10 ft and while standing within 20 to 25 ft from heavy equipment, pneumatic
power tools, steam cleaners, and other equipment in operation that can generate more
than 85 decibels (A-weighted scale) (dBA).
. Slips, Trips, and Falls - Clear work area of obstructions and debris before setting up.
Alter work areas as necessary to provide a safe, reasonably level area. All walking and
working surfaces shall mntinually be inspected and maintained to be free of slip, trip,
and fall hazards. Keep platforms, stairs, and immediate work areas clear. Do not allow
oil, grease, or excessive mud to accumulate in these arcas. Eliminate slip, trip, and fal!
hazards or identify them clearly with caution tape, barricades, or equivalent means.
Store loose or light material and debris in designated areas or containers. Secure tools,
materials, and equipment subject to displacement or falling.
o Traffic Control - lf site activities interrupt the normal flow of pedestrian or vehicular traffic,
banicades and waming signs which comply with the Manual on Unifonn Traffic Control
Devices and/or State or local ordinances will be erected around affected equipnrent.
Safety omnge work vests will be wom by personnel working within 10 feet of any active
roadway. All borings or partially completed groundwater monitoring wells will be
adequately epvered and/or barricaded if left unattended for any period of time.
8.0 SITE CONTROL
An Exclusion Zone, Contaminant Reduction Zone and a Support Zone will be established
whenever project activities require Level C or Level B personal protective equipment. Defined
access and egress points will be established and personnel will enter only through those points.
As permitted by site topography, the area within a 50 foot radius of a drill rig and 100 foot radius
of UST removal excavation shall be considered the Exclusion Zone. Only those personnel
designated by the Project Manager/SSO are allowed to enter the Exclusion Zone. Where
practical, or where their use will prevent public injury, temporary signs or barricade fencing will
be established to define the Exclusion Zone. ABSOLUTELY NO SMOKING WILL BE
PERMITTED WITHIN THE EXCLUSION OR CONTAMINANT REDUCTION ZONES ON ANY
PETROLEUM CONTAMINATED SITE.
!f unauthorized personnel attempt to enter the exclusion zone, the SSO will verbally inform the
individual(s) to leave the project site. lf unauthorized individuals refuse to leave the Exclusion
Zone or are considered in danger or pose danger to project personnel, the SSO will cease
project activities (i.e., shut down drill rigs, excavation equipment, etc.) and notify the client
representative or the local police of the situation. Site activities will not resume until
unauthorized personnel have left the project site.

9.0 AIR MONITORING AND SITE ACTION LEVELS
This air monitoring protocol is designed to prevent personnel exposure to airborne contraminants
in exoess of established permissible exposure limits. The results of field air monitoring will be
used to determine the continued adequacy of initial personal protective equipment.
Air monitoring equipment required for petroleum contaminated sites will include the following:
r PhotoionizationDetector
Task Leader(s) will be knowledgeable in the operation of the photoionization detec*or. A
manual on the operation of the PID and the appropriate calibration kit will be mobilized to the
project site with the instrument. Photoionization detectorc will be calibrated under field
conditions each day prior to use. Task Leaders are instructed to consult the manufacture/s
specifications for appropriate calibration gas and calibration techniques.
A photoionization detector (PlD) will be used to determine approximate hydrocarbon vapor
conentrations in the BREATHING ZONE of site personnel. Continuous breathing zone air
monitoring will be conducted during initial phases of intrusive activities (i.e., boring, excavation).
lf PID readings are less than 10 ppm, monitoring may be conducted at intervals of 10 minutes.
lf initial PID readings exceed 10 ppm, or if hydrocarbon odors become evident upon during
auger advancement, continuous breathing zone air monitoring will be conducted..
lf sustained PID readings in the breathing zone exceed 25 ppm, personnel will upgrade to
respiratory protection as outlined below. Personnel will remain in air purifying respirators until
the photoionization detector readings in the breathing zone have fallen and stabilized below 25
ppm.

The Action Levels indicated above are for air in the breathing zone and NOT applicable to vapor
above containerized soil samples. The Action Levels are established to prevent exposure to
airborne petroleum hydrocarbon vapors in excess of established exposurc limits. Although the
Action Levels indicated for Site Evacuation are within the protective capacity of the respinator
cartridges specified below, personnel will evacuate to the UPWIND side of the site if the
continuous breathing zone vapor concentrations exceed these limits. The SSO will contact the
Corporate Safety and Health Manager for discussion and re-evaluation of personal protective
equipment and air monitoring requirements if airbome contamination exceeds Site Evacuation
Action Levels. ln the event that site evacuation is required, a modification of this safety and
health plan will be issued with contingencies for combustible gas monitoring and upgrading to
Level B personal protective equipment.

The SSO and at teast one other individual on site will be appropriately trained to administer first
aid. A certificate issued by the American Red Cross, National Safety Council or equivalent will
be considered acceptable.
For minor injuries, such as cuts, burns, exhaustion, heat cramps, insect stings, etc., the affected
employee will be removed to an uncontaminated area. The SSO or other designated employee
trained in first aid procedures will administer appropriate first aid. lf the injury wanants additional
medicalattention, the affected employee will be properly decontraminated and transported to the
nearest hospital or emergency medical facility.
For more serious injuries the Site Safety Officer or designee will summon an ambulance to the
pQect site. No attempt will be made by Terracon personnelto move the victim, without the aid
and/or instructions of qualified medical personnel.
Where air monitoring indicates the absence of toxic gases or vapors, the ambulance will be
directed to the affected employee. lf site conditions wanant and as time permits, the wheels of
the ambulance will be decontiaminated with high pressure wash. The SSO or designee will
accompany the ambulance to the medical facility, and provide guidance coneerning additional
decontamination which may be required for the injured employee, ambulance or attendants.
Whenever an injury occurs on sites with contamination requiring personal protective equipment
greater than Level D modified, a minimum of two employees will don appropriate equipment and
proceed to the victim. An ambulance will be called immediately. lf the extent of injuries permit,
the injured employee will be removed to fresh air. Appropriate first aid will be administered.
lf rescuer(s) assess that the victim cannot be removed without a stretcher or other specialized
equipment, the victim will be removed at the earliest possible moment by appropriately attired
Tenacon personnel with the direction and/or assistance of qualified medical response
personnel. The injured employee will be immediately decontaminated and transported to the
nearest medicalfacility. A crew member designated by the SSO will inform the ambulance crew
of contaminants of con@rn and provide assistance with additional decontamination if required.
13.2 Evacuation and Shutdown Procedures
The SSO will establish and notify site personnel of emergency "rally" points. ln the event of a
site emergency, personnel will immediately exit the site and assemble at the designated rally
point. Evacuation routes will be dependent on site topography and wind conditions. The routes
will be selected and presented by the SSO daily prior to site activity.

lf emergency evacuation becomes nec€ssary, the SSO will sound the emergency alarm (e.9.
support vehicle horn or compressed air hom). Personnel will safely shutdown all electrical and
mechanical equipment and quickly proceed to closest designated rally point. The SSO willthen
account for each crew member on site.
ln the event that a Terracon employee does not report to the designated rally point within 5
minutes of the evacuation alarm, the SSO will perform an immediate assessment of site
conditions. lf site conditions do not pose an immediate hazard to life or health, the SSO will
initiate search and rescue efforts utilizing two crew members attired in appropriate personal
protective equipment.
14,0 HEAT STRESS
14.1 @
Whenever ambient temperature exceeds 70 degrees F and personal protective equipment
requirements are Level D or Level D modified, the following heat stress monitoring and
preventive measures will be implemented.
At least one gallon of water will be available for each field employee during each day of site
activity. The designated Site Safety Officer and one designee will observe personnelfor signs of
heat stress (excessive percpiration, flushed skin, nausea, etc.).
lf such signs are observed, affected workers will be required to leave the contaminant zone,
loosen protective clothing and rest. During the rest period affected personnel will drink at least
one 8 oz. glass of cool water. Pulse will be checked at the beginning of the rest period.
Personnelwill not return to work until pulse rate is less than 90.
14.2@
ln addition to the above precautions, the following procedures will be implemented whenever
the ambient temperature exceed 70 degrees F and personal protective equipment requirements
are Level C or above. Ambient temperature will be measured with a dry bulb thermometer and
percent cloud cover will be estimated:
1.0 = No Clouds
0.75 = 25% Clouds0.5 = 50o/o Clouds
0.25 = 75% Clouds0.0 = 100o/o Clouds).
Calculate the adjusted temperature using the following formula:
ADJUSTED TEMPERATURE = 13(% CLOUD COVER) + DRy TEMPERATURE
Rest regimens and physiological monitoring (oraltemperature and radial pulse) willbe
implemented at frequencies dependent upon adjusted temperature.

Employees will return to work only after oral temperature is below 99.7 degrees F and pulse rate
< 90. Fluid replacement will be encouraged during each rest period. The use of stimulants and
alcoholic beverages in off hours will be discouraged.
15.0 COLD STRESS
Percons working outdoors in low temperatures, especially at or below freezing are subiect to
cold stress. Exposure to extreme cold for a short time can cause severe injury to the surface of
the body or result in profound gener:alized cooling which, in extreme cases, can lead to coma
and death. Areas of the body which have high surface area, such as fingers, toes and ears are
most susceptible.
Protective clothing generally does not provide protection against cold stress. ln many instiances
it may increase susceptibility due to excessive perspiration which can rapidly cool the body
when exposed to cold, windy conditions. The greatest incremental increase in wind chill occurs
when a wind of 5 mph increases to 10 mph. And, because water conducts heat approximately
240 times faster than air, the body will cool rapidly when chemical protective equipment is
removed if undergarments are saturated with perspiration.
Whenever ambient temperatures are expected to be below freezing, Tenacon personnel will
consult the cold strcss section of the Tenacon Safety and Health Policy and Procedures Manual
to re-familiarize themselves with signs, symptoms and treatment of cold injuries. Thermal boot,
glove and hard hat liners will be mandatory for all personnel conducting field activities in
ambient temperatures below freezing.
ACKNOWLEDGMENT OF INSTRUCTION
All Terracon personnel are required to sign the following acknowledgment of instruction form
prior to conducting project activities. This acknowledgment is not a waiver. lt is the primary
method used in compiling environmental experience and contaminant exposure records for
Terracon personnel. Upon written request, a copy of your environmental work record will be
provided by the Corporate Safety and Health Manager.
I underctand that this project involves the removal of soil containing petroleum hydrocarbon
contamination from the subject site. I have read this Safety and Health Plan and have received
instructions for safe work practices, personal protective equipment and air monitoring
requirements. I further understand that if I encounter unanticipated contamination ! am to leave
the site and immediately notify the Project Manager and Corporate Safety and Health Manager
of conditions disovered.
