Analysis of Brownfield Cleanup Alternatives
Former Regal Manufacturing
Hickory, North Carolina
H&H Job No. IDC-001
1.0 Introduction and Back,<>round
Hart & Hickman, PC (H&H) has prepared this Analysis of Brownfield Cleanup Alternatives
(ABCA) fur the Fonner Regal Manufacturing located in Hickory, Catawba County, North
Carolina on behalf of the City of Hickory under the City's US EPA Region 4 Brownfield
Assessment Grant (BF-96489707). This ABCA report was prepared to identizy and evaluate
cleanup alternatives to mitigate potential risks to human health and the environment from
identified environmental impacts at the site.
1.1 Site Description
The subject site is located at 212 12'h Avenue NE in Hickory, North Carolina (Figures 1 and 2).
The property is comprised of four parcels totaling approximately 2.64 acres. Three parcels (2.03
acres) are located between 12'h A venue NE and 11th Avenue l'.'E and they are occupied by the
former manufacturing area. One parcel contains an approximate 47,000 sq ft vacant building,
one parcel contains an asphalt-paved parking area, and one parcel contains an approximate 2,000
sq ft vacant building. The fourth parcel is located south of 11th Avenue NE (306 11 "' Avenue
l\"E) and it contains an asphalt-paved parking area sunounded by a fence. Although no finn
plans have been generated for site redevelopment, it is anticipated the site will be redeveloped
commercial or light industriaL

Hart & Hickman, PC
1.2 Site History
The subject site was first developed as a hosiery mill in 1956 and was then comprised of the two
westernmost buildings (former machine shop and former cotton yarn manufacturing buildings),
which are now incorporated into the current manufacturing building (Figure 2). The larger
eastern building (former elastic yarn manufacturing warehouse) was added by Regal sometime in
the 1960s or early 1970s. The former aiT compressor building has been present since at least
1961, and it was formerly operated as an automotive repair facility in the 1960s. The asphalt-
paved parking area was added sometime in the 1960s and has served only as a parking lot.
Various textile companies occupied the manufacturing buildings between the 1950s and 1960s.
The companies included the Reaco Hosiery Mills, Madaris Hosiery Mill, The Elastic
Corporation, and Realspan Corporation before becoming Regal Manufacturing in the 1960s.
Regal used the facility to manufacture hosiery and cover elastic until 1999. The site buildings
have been vacant since 1999.

2.0 Summary of Site Characterization and Environmental Impacts
2.1 Previous Environmental Investigations
Recent reports and project plans for the site prepared by H&H as part of the Brownfields
assessment activities include:
• Quality Assurance Project Plan for Brownfields Assessment, October 19,2009.
• Brownfield Phase II Site Assessment Report, June 1, 2010.
ln addition, three previous reports were prepared for the site by Gaia Tech, Inc. (GaiaTech) prior
to the Brownfields assessment activities:
• Phase I Environmental Site Assessment (ESA), November 18,2001.
• Focused Phase II Investigation Letter of Findings, January 2, 2002.
• Limited Phase II Site Investigation, June 2007.
2.2 Site Lithology
The description of lithology in this ABCA is based on the subsurface activities conducted during
the Brownfield site assessment activities remedial in January and March 2010 and previous
investigations conducted in 2007 by GaiaTech. During the 2010 Brownfield site assessment
activities, a total of nine soil borings were advanced at locations across the site using a direct
push technology (DPT) rig. Three of the soil borings were converted into monitoring wells (TW-
1 through TW-3). Soil borings and monitoring wells installed by H&H and otl1ers are shown on
Figure 2. The assessment results are discussed in Sections 2.4.1 and 2.4.2.
Based on investigation activities conducted at the site, the lithology generally consists of orange
to brown sandy silts to silty sands. The depth to partially weathered rock ranges from
approximately 38 to 45 feet below grmmd surface (bgs). Competent bedrock was not
encountered during the Brownfield site assessment activities. According to the North Carolina
4
Hart & Hickman, PC
Geological Survey 1985 Geologic Map of North Carolina, bedrock in the area of the subject
property is characterized as mica schist.
2.3 Site Ground Water Flow Direction
Ground water at the site was investigated thorough the installation of three temporary ground
water monitoring wells, and sampling four existing permanent monitoring wells installed by
Gaia Tech in 2007. Well construction details and calculated ground water elevations are provided
in Table 1. Ground water ranged in depth across the site from approximately 31 feet bgs to 41
feet bgs during the water level survey conducted on January 22, 2010.
A ground water elevation contour map was generated from the January 2010 data to evaluate
ground water flow direction at the site (Figme 3). Grotmd water elevations obtained from the
site monitoring wells infer a shallow ground water flow direction to the southwest. This is
consistent with the topographic gradients in the area.
2.4 Characterization of Environmental Impacts
Environmental impacts at the site are characterized based on a review of 2007 assessment data
collected by GillaTech and the results of the Brownfield Phase II Site Assessment condueted by
H&H in January and March 2010. Key fmdings of the assessment activities are summarized
below. 1be Brownfield Phase IT assessment sample locations are provided on Figure 2. The
results of the soil analyses are summarized in Table 2 and on Figure 4, and the results of the
grotmd water analyses are summarized in Table 3 and on Figme 5. Copies of pertinent portions
of Gaia Tech's assessment doctm1ents are provided in Appendix A.

2.4.1 Soil Impacts
2002 Focused Phase II Investigation Soil Results
The 2001 GaiaTech Phase I ESA indicated that a former gasoline underground storage tank
(UST) was reportedly removed from the western side of the property in the late 1980s. No
closure documentation is available for the removal activities.
To assess site impacts from the former UST, Gaia Tech collected four soil samples in the vicinity
of the former UST during the January 2002 focused Phase II Investigation. Soil samples were
analyzed for gasoline range total petroleum hydrocarbons (TPH-GRO), volatile orgaaic
compounds (VOCs), and lead (no ground water samples were collected). No VOCs or TPH-
GRO concentrations were detected in soil samples above the laboratory detection limits, and lead
was detected at concentrations within the EPA published background concentration range.
2007 Limited Phase lT Site Investigation Soil Results
GaiaTech collected eight soil samples and seven ground water samples at the site as part of the
Limited Phase II Site Assessment activities in 2007. No soil impacts were detected in the soil
samples.
Brownfield Phase II Site Assessment Soil Results
Results of 2010 Brownfield assessment activities indicate PCE and TCE were detected in soil
sample SB-9 (2-4') at concentrations above NCDENR's Inactive Hazardous Sites Branch (IHSB)
Health-Based Soil Remediation Goals (SRGs), January 2010. In addition, the detected PCE
concentration in SB-9 (2-4') also exceeded the USEPA Industrial Soil Regional Screening Level
(RSL) presented in the USEPA RSL Master Table Update (May 2010). No other VOCs were
detected in SB-9 and no VOC compounds were detected above the soil screening criteria in any
of the remaining soil samples. Additionally, no SVOC compounds were detected above the soil
screening criteria in any of the soil samples.
6
Arsenic was detected at a concentration above its soil screening criteria in the shallow soil
samples (up to 16 mg/kg). However, the detected arsenic concentmtions were within the
published KC background concentration range.
It is important to note that during the Brownfield Phase II Site Assessment, a suspected heating
oil UST was discovered beneath the southwestern buililing walL At the request of the property
owner, no samples were collected in the vicinity of the UST during H&H's Brownfield Phase II
Site Assessment
2.4.2 Ground Water Impacts
2007 Limited Phase II Site Investigation Ground Water Results
GaiaTech's 2007 ground water analytical results inilicated PCE concentrations as high as 280
Jlg/l and TCE concentrations as high as 58 Jlg/1 in the southwestern corner of the property. Ko
grourtd water impacts were detected in the ground water samples collected along the northern,
western, and eastern property boundaries.
Brownfield Phase II Site Assessment Ground Water Results
H&H's 2010 Brownfield assessment results for ground water indicate PCE was detected at
concentrations above the 2L Standard in monitoring wells MW-1, MW-2, TW-1, and TW-2.
Additionally, TCE was detected at a concentration above the 2L Standard in monitoring well
MW-2. Ko VOCs were detected in MW-3, MW-4, and TMW-3. Additionally, SVOCs were not
detected in any of the samples analyzed.
Manganese was detected above its 2L Standard in monitoring wells MW-1, MW-2, MW-4, TW~
2, and TW-3. The basis for the 2L Standard is the EPA Secondary MCL for manganese.
Secondary MCLs are based on aesthetic qualities such as color, taste, odor, etc. The presence of
manganese in ground water at the site is believed to be naturally occulTing at all well locations
with the possible exception ofTW -2.

3.0 Cleanup Goals and Objectives
The primary cleanup objective for the site in the context of a Brownfields redevelopment is to
reduce or prevent potential risk to future site workers engaged in redevelopment efforts, and
future users of the site after redevelopment. Primary coneems are related to the potential for
exposure of these populations to contaminants identified in site shallow soil, ground water,
and/or vapors.
Although no firm plans have been generated for site redevelopment, it is anticipated the site will
be redeveloped commercial or light industriaL Therefore, H&H has established cleanup
objectives based on available site information and based on conservative assumptions of future
site uses including commercial or light industrial. If residential uses were to be planned for the
site, more stringent cleanup goals will likely apply.
3.1 Soil Cleanup Goals
As previously discussed, a suspected heating oil UST was discovered during H&H's Brownfield
Phase II Site Assessment. The suspected heating oil UST should be assessed and closed in place
or removed in accordance with NC DENR UST Section requirements. The cleanup goals
pertaining to the suspected UST at the site are based on DENR, Underground Storage Tank
Section Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement,
December I, 2008. The UST guidelines address UST closure, release response, and abatement
activities that would apply to UST closure at the site. The UST guidelines also establish
maximum soil contaminant concentrations (NISCCs) for different exposure pathways.
Based on available site data, H&H believes that the DENR UST Section will classify the
potential UST release, if any, as low risk. With a low risk classification of the UST release, the
remedial goals for soil are based on ingestion values for a given site user (i.e., residential or
industriaVcommercial). Since the future site use is anticipated to be commercial, the applicable
8
Hart & Hickman, PC
soil cleanup goals for potential petroleum impacted soil detected at the site are the UST Section
industrial/commercial MSCCs.
As discussed in Section 2.4.1, PCE and TCE exceed the Health-Based SRGs in soil sample SB-9
(2-4'). In addition, PCE also exceeds the USEPA Industrial RSL in SB-9 (2-4'). Based on the
anticipated future land use of commercial or light industrial, the recommended soil cleanup goals
to address the remediation of shallow PCE and TCE impacted soil in the vicinity of soil boring
SB-9 are the USEP A Industrial RSLs. This recommendation is premised on the expectation that
redevelopment at this property will be conducted tmder the NCDENR Brownfields Program.
During site redevelopment, impacted soil also may be encmmtered in other areas. Cleanup goals
for these currently unidentified impacted soil areas should be based on appropriate regulations.
3.2 Ground Water Cleanup Goals
Analytical data for ground water samples collected during the Brownfield Phase II Site
Assessment indicated the presence of PCE, TCE, and manganese in certain monitoring wells in
excess of their respective NC 2L Ground Water standards. Ground water at the site and
surrounding area is not used as a source of drinking water. In addition, due to the depth of
ground water (approximately 31 to 4 I feet bgs), it is not anticipated that ground water would be
encountered during site construction activities. As a result, gronnd water does not pose a
drinking water risk to future site occupants or a dermal contact risk to future site
construction/utility workers.
During the Brownfield Phase II Site Assessment, an evaluation of the risk of vapor intrusion for
the current and future site buildings indicated that concentrations of PCE in ground water in the
vicinity of MW-1, MW-2, and TW-2 are sufficiently elevated to pose a potential vapor intrusion
risk to future site occupants. These findings are summarized on Table 4. The evaluation utilized
the Johnson-Ettinger model, OW-ADVANCED, Version 3.1 dated February 2004. Vapor
9
Hart & Hickman, PC
intn1sion modeling indicated PCE represents a potential vapor intrusion risk of 2.1 x 10-5 to
occupants if a building were constructed above monitoring well MW-2. Alternatives to mitigate
vapor intrusion concerns above MW-2 are discussed in Section 4.0.
To assess potential vapor intrusion concerns within the site buildings situated hydraulically
upgradient of MW -2, a site-specific Acceptable Ground Water Concentration for the former
elastic yam manufacturing building was back -calculated to represent a conservative lifetime
incremental cancer risk (LICR) of 1 x 10-5• The iterative back-calculation indicated a ground
water PCE concentration of 300 Jlg/1 or lower represents an acceptable vapor intnJSion risk for
the building. Because PCE has not been detected above 300 Jlg/1 in any monitoring wells located
inside or immediately outside the site buildings, it is judged that the vapor intmsion risk is at
acceptable levels within the existing site buildings.
10
4.0 Cleanup Alternatives Analysis
4.1 Cleanup Alternatives Development
Based on the evaluation of assessment findings presented in this ABCA and our current
tmderstanding of the future site uses, H&H developed potential cleanup alternatives for the
suspected heating oil UST; shallow PCE impacted soil in the vicinity of soil boring SB-9; and
ground water in the vicinity of MW-2 impacted with PCE (in the event a building were to be
constructed above MW-2). Alternatives for managing these potential sources are discussed
below.
4.1.1 Soil Alternatives
No Action
A no-action alternative must be considered as part of the ABCA process and is a viable option
for impacted soil near soil boring SB-9 as discussed below because this area is currently capped
with asphalt and/or concrete. The no-action alternative is not judged to be a viable alternative for
the suspected heating oil UST because the nature and extent of a release, if any, is not yet !mown.
Source Removal and Off-Site Disposal
Source removal and off-site disposal of impacted shallow soils eliminates the potential for site
worker and future site user exposure to impacted soil and allows for meeting more conservative
residential soil cleanup standards. Source removal and off-site disposal may be a viable remedial
alternative for impacted shallow soil near soil boring SB-9. Due to the isolated occurrence of
PCE and TCE soil impacts, arsenic impacts within the published NC backgTotmd concentrations,
and anticipated future use of the site, somce removal and off-site disposal of impacted soil is not
judged to be the most eost-effective remedial altemative. Separately, excavation and disposal of
impacted soil from cunently unidentified sources may be necessary if such soils are encounteTed
during potential future construction activities.
11
Source removal and off-site disposal may be a viable remedial alternative for potential impacted
soil, if any, beneath the suspected heating oil UST.
Capping
Capping of contaminated soil is a viable remedial alternative that addresses exposure risks by
creating a barrier between the future site user and the contaminated soiL Capping can be used on
its own or in concert with source removal methods. Remedial capping materials can vary
depending upon site considerations, but their design can include asphaltic paving, layers of
geotextile materials, hardscape surfaces, clean subsoil fill materials with a clean soil and
vegetated layer, or buildings. The placement of a remedial cap over contaminated soil minimizes
the surface exposure to the soiL Capping is often an integral component in Brownfield remedial
actions and is considered to be part of sound remedial strategy for this site.
The ground surface in the vicinity of impacted soil boring SB-9 is currently covered with asphalt
and/or concrete. If this area is undisturbed in the redevelopment process, the asphalt and
concrete covered surfaces could be used as a cap for the subject site in lieu of excavating shallow
impacted soil.
In-Situ Remedial Methods for Soil
In-situ soil remedial methods such as soil vapor extraction or in-situ chemical oxidation methods
are not considered viable at this location due to the limited extent of impacted soiL Therefore,
in-situ soil remedial methods are not considered further in this doewnent.
4.1.2 Ground WaterNapor Intrusion Alternatives
No Action
A no-action alternative for addressing grmmd water impacts must be considered as part of the
ABCA process. While the no-action alternative is a low cost alternative, it would not allow
future construction of buildings in the vicinity of monitoring well MW -2 due to the potential
12
Hart & Hickman, PC
vapor intrusion risk posed by PCE in ground water at MW -2. Because of the potential future
redevelopment near MW -2, the no-action alternative was eliminated fi·om further consideration.
In-situ Ground Water Remedial Methods
111-situ ground water remedial methods such as ground water pump and treat, and air sparging, as
well as other remedial actions are not judged to be warranted at this site due to the limited area of
impacted ground water, the absence of grotmd water users, and lack of sensitive receptors within
1,000 feet of the site. Given these factors, the installation and operation of an active ground
water remediation system is not considered to be warranted. Therefore, in-situ ground water
remedial methods are not considered further in this document. This recommendation is premised
on the expectation that redevelopment at this property will be conducted under the NCDENR
Brownfields Program.
Vapor Intrusion
AB discussed in Section 3.2, based on vapor intrusion modeling, it is judged that the vapor
intrusion risk is at acceptable levels within the existing site buildings. Therefore, vapor intrusion
mitigation is not considered to be warranted for the existing buildings.
Should a building be constructed south of the former elastic manufacturing warehouse above
monitoring well MW-2, vapor intrusion mitigation may be required. Mechanical ventilation of
commercial buildings with outdoor air is required in compliance with the most current version of
the Mechanical Ventilation Section of the Ventilation Chapter of the N01th Carolina State
Building Code. In addition, passive ban'iers are required beneath building slabs for new
construction. These technologies are relatively inexpensive to install during building
constmction activities and can effectively mitigate vapor intrusion concerns. Vapor intrusion
mitigation can be addressed with a variety of engineered systems during construction of potential
future buildings above monitoring well MW -2. Three types of vapor barrier systems are
considered below.
13
Hart & Hickman, PC
Passive Barrier
Passive barriers are installed below a building to physically block entry of vapors. Most passive
barriers are synthetic flexible membranes placed beneath the floor slab to prevent subslab soil gas
from entering the structure through cracks or construction joints in the slab. Passive barriers may
not result in complete elimination of vapors due to the high potential for imperfections (e.g.,
penetration, tears, incomplete seals), but in instances where minimal reductions in vapor
intrusion rates are required, passive barriers may be sufficient. As noted above, passive barriers
are required to be installed during building construction as part of the State Building Code.
Furthermore, installation of passive barriers is typically specified in Brownfield agreements. The
installed cost for this type of system ranges from $0.50 to $3 per square foot of building area
depending on the type of material used for the barrier.
Passive Ventilation System
A passive ventilation system involves placing a venting layer below the floor slab to allow soil
gas to move laterally beyond the building footprint. Passive venting systems are placed below
passive barriers to be most effective. The venting layer typically consists of permeable material,
such as sands or pea gravel, with perforated collection pipes routed at the peliphery or through
the venting media to collect soil gas and convey it to an exhaust point outside the building. The
installed costs for these systems range from $1 to $4 per square foot of building area, excluding
the cost of a passive vapor barrier (see above).
Active Ventilation System
An active ventilation system ftmctions by pulling soil gases from beneath the slab and venting
them to the atmosphere at a height well above the outdoor breathing zone and away from
windows and air supply intakes. In new construction, active ventilation systems are similar to
passive venting systems except that a fan is used to draw soil gas through the subslab venting
layer prior to discharging it to the atmosphere. The inBtalled capital costs for these systems range
from $2 to $5 per square foot of building area. In addition, there are annual operation and
maintenance costs associated with mnning the blower.

4.2 Ground Water Encountered During Construction
Ground water is not anticipated to be encountered during constmction. However, if ground
water is encountered during constmction activities, it should be properly handled to prevent
exposure of constmction and utility workers at the site to the chlorinated solvent constituents
detected in ground water. Contaminated water from de-watering activities during construction
should be treated to meet discharge levels allowed at a POTW or NPDES permit, or must be
properly containerized and disposed of at a permitted facility.
4.3 Newly Discovered Impacted Soil
Impacted soil not associated with the current kuown extent of soil impacts may be encountered in
other areas of the site during construction activities. Impacted soil that is encoootered should be
characterized and the data compared to appropriate regulatory standards. If conective action is
judged to be necessary, the soil should be managed using ex-situ techniques such as excavation
and off-site disposal, or managed in place with capping and/or institutional controls, as
appropriate.
4.4 Institutional and Engineering Controls
If residual impacted materials are left in place, institutional controls may be required.
Institutional controls are implemented when residual contaminants in excess of regulatory
threshold eleanup values remain at a site. This may inelude a deed restriction for the property,
which would identify areas of residual contamination, and prohibit the future use of site ground
water as a source for potable or non-potable water.
15
Hart & Hickman, PC
4.5 Proposed Remedial Actions
On the basis of effectiveness, technical feasibility, and cost, and assuming potential future
commereial use of the subject site, H&H recommends a combination of remedial approaches as
described below. This recommendation is premised on the expectation that redevelopment at
this property will be conducted 1mder the NCDENR Brownfields Program.
UST and UST-Related Impacted Soil
As previously discussed, the suspected heating oil UST should be assessed and closed in place or
removed in accordance with NC DENR UST Section requirements. However, because the
suspected heating oil UST is located beneath the southwestern wall of the former machine shop
and laboratory building, we do not recommend attempting to remove the UST ·until the site
redevelopment planning is completed.
If the former machine shop and laboratory building is not demolished for redevelopment
purposes, the existing UST may be closed in place with approval of NC DENR. Soil samples
should be collected for chemical analyses during in-place closure. In addition, the installation
and sampling of a monitoring well will be required at the UST location during the in-place
closure. Because gmund water in the site vicinity is not used for drinking water purposes, we
anticipate that NC DENR will classify the site as a low risk site if impacts are detected.
In the event that the UST and impacted soil are removed, soil samples should he collected from
the sidewalls and base of the excavation for chemical analysis, and the excavation should be
backfilled with clean fill. A Limited Site Assessment (LSA) and associated monitoring well may
be required at the UST location if soil excavation does not remove all of the required soil
contamination.
16
Hart & Hickman, PC
Shallow Impacted Soil
PCE and TCE exceed NCDENR's Health-Based SRGs in soil sample SB-91ocated south of the
former elastic yarn manufacturing warehouse. Additionally, PCE also exceeds the USEPA
Industrial RSL in SB-9. This area is currently capped with asphalt and/or concrete. To minimize
worker and future site user exposure to the soil, H&H recommends avoiding redevelopment in
this area of the site and leaving the asphalt and concrete surface cap intact. Should it become
necessary to disturb soil impacts near SB-9 during site redevelopment, the impacted soils should
be managed through excavation and off-site disposal.
Site Ground Water
Due to the likelihood of DENR assigning a low risk classification for the suspected heating oil
UST at this site, H&H does not recommend remediation of contaminated ground water in
association with the suspected heating oil UST. Separately, H&H does not recommend
remediation of PCE, TCE, and manganese detected in ground water exceeding the 2L Standards
because of the limited area of impacted ground water, the absence of ground water users, and
lack of sensitive receptors within 1,000 feet of the site. H&H recommends that a ground water
use restriction be recorded on the property deed prohibiting ground water use for any purpose at
the property. Additionally, monitoring wells MW-1 through MW-4 should be properly
abandoned during site redevelopment.
In addition, contaminated ground water, if encountered during future construction activities, will
need to be either contained and disposed of off-site, or treated and discharged tmder local
permitting regulations to the local POTW. The appropriate approach will depend upon the
volume and degree of contamination of ground water that 'Will need to be addressed.
Based on vapor intmsion modeling, PCE represents a potential vapor intrusion risk if a building
were to be construrted south of the forrner elastic yam manufacturing warehouse near monitoring
well MW-2. To minimize the risk associated wit11 potential vapor intmsion ofVOC constituents,
17
Hart & Hickman, PC
the installation of a passive banier system beneath future buildings constructed is this area is
recommended.
4.6 Cost Estimate for Proposed Cleanup Alternative
Hart & Hickman has estimated the costs of mitigating the risks posed by site contaminants based
on the recommended cleanup alternative described in Section 4.5. This cost estimate is based on
the assumptions and criteria discussed below.
The estimated costs are presented in Table 5, and assmne the following:
• In place closure or removal and assessment of the suspected heating oil UST;
• Preparation of a Brownfields Property Application and negotiation of a Brownfields
Agreement for the site;
• Impacted soil near soil boring SB-9 will remain nndistarbed and capped. If disturbed, the
impacted soils should be managed through excavation and off-site disposal;
• No active ground water remediation, but a deed restriction will be used to prohibit the use
of gronnd water at the site for any purpose;
• Proper abandonment of the three pelTllanent on-site monitoring wells; and,
• If new buildings are to be constructed south of the former elastic yam manufacturing
•varehouse, passive vapor barrier systems vv:ill be installed and the cost accounted for in
the construction costs.
The estimated costs for the proposed cleanup activities are shown in Table 5 and include a 30%
contingency for unknown conditions that may be encountered during redevelopment activities.
As noted on Table 5, the estimated cost for the proposed cleanup activities at the subject site
ranges from approximately $26,260 to $58,500. The low range cost estimate assumes the UST is
removed from the ground and the UST has not leaked, and the high range cost estimate assumes
the UST is removed from the ground and the UST has leaked. Additionally, the high range eost
I8
Hart & Hickman, PC
estimate also assumes up to 200 tons of impacted soil will be removed from beneath the VST and
an LSA and associated monitoring well will be required.
Separately, the eost estimate addresses non-UST issues under the assumption they will be
managed under the NCDENR Brownfields Agreement.

5.0 Schedule
This ABCA will be stored in the City's repository until a perspective developer is located for the
property. When the property owner comes to an agreement with a prospective developer to
purchase and redevelop the site, and if that developer elects to enter the site into the NCDENR
Brownfields program, the perspective developer can submit the ABCA to NCDENR to assist in
negotiating a NC Brownfield Agreement for the property. Once the Brownfields Agreement is
fmalized, the prospective developer can then complete their redevelopment planning and design,
conduct the required corrective actions, and redevelop the property to return it to productive use.
With DENR's review and public comment periods in mind, we anticipate that site activities
could be initiated as soou as three to four mouths followiug NC Brownfields Agreement approval
by DENR. Once begun, site cleanup activities should take approximately tiu·ee to six weeks.

RE: Focussed Phase II Investigation Letter of Findings: Elastic Corporation of America -
Columbiana, AL, Elastic Corporation of America -Lexington, SC, and Regal
Manufacturing, Hickory, NC Facility
Dear Mr. Setzer:
GaiaTech has completed the scope of work outlined in our November 28, 2001 proposal letter for the
following facilities:
Elastic Corporation of America
102 Industrial Road & 455 Highway 70 West
Columbiana, Alabama
Elastic Corporation of America
130 Zenker Road
Lexington, South Carolina
Regal Manufacturing
212 12" Avenue NE
Hickory, North Carolina
This letter provides preliminary details of the findings of the Focussed Phase II Investigations
authorized by WorldTex on December 6, 2001
Field sampling activities were conducted at each of the facilities on December 5 and 6, 2001. Initially,
soil borings were created in the areas of concern (AOC) identified in the Phase I Environmental Site
Assessments (ESAs) previously performed by GaiaTech. Subsurface soil and groundwater sampling
was facilitated by the use of truck-mounted Geoprobe® drill rigs at each of the facilities. These soil
borings were intended to provide additional assessment of subsurface conditions and potential impact by
contaminants of concern (COC), Subsequent to completion of the borings, select borings were

converted to temporary groundwater sampling points. Groundwater was sampled from many of these
locations and prepared for ·laboratory analyses. Upon completion of soil and groundwater sampling
activities, temporary well casings were removed and the boreholes were backfilled in an appropriate
manner.
In summary, no evidence of subsurface impact was identified at the Lexington, South Carolina or
Hickory, North Carolina locations and no further investigation or action is warranted at these facilities.
Trace concentrations of total lead and vinyl chloride were found slightly exceeding the applicable
standards groundwater samples collected at the Columbiana, Alabama location. It may be appropriate
for legal counsel to advise on potential release reporting obligations to the State that these detections
may require. No other evidence of impact was identified in soil or groundwater exceeding applicable
standards. The detected total lead concentrations are most likely attributable to natural background
levels rather than evidence of a release. Although the vinyl chloride detection is isolated to a single
sample location, further investigation may be required by Alabama to confirm !be concentration and
demonstrate that it does not represent a likely potential to adversely effect human health and/or the
environment. GaiaTech has been requested to conduct additional sampling at the Columbiana facility
and will issue a supplemental report and recommendations by January 18, 2002.
Columbiana, Alabama
The following AOCs identified by GaiaTech during the ESA were addressed as part of the subsurface
sampling scope of work:
• Adjacent facility to the north of the 102 Industrial Road facility (north parcel) has been involved in
remedial action regulated by Alabama Department of Environmental Management (ADEM).
• Trench drains of unknown construction and condition exist at the 455 Highway 70 West (south
parcel) location.
• Drilled holes in the floor near the dye rnL,ing station in the building located on the south parcel.
Soil Analytical Results
Four soil borings were installed on the south parcel (SB-01 through SB-04). These borings extended to
approximately 10 feet below ground surface (bgs). Four soil borings were installed on the north parcel
(SB-05 through SB-08). These borings ranged from approximately 5 to 15 feet bgs, several of whlch
were terminated on top of bedrock. Select soil samples were analyzed for volatile ·organic compounds
(VOCs), semi-volatile organic compounds (SVOCs), 8 RCRA metals, and polynuclear aromatic
ydroearbons (PAHs). Analyses of soil samples obtained from these borings do not indicate significant
exceedance of ADEM or United States Environmental Protection Agency (EPA) screening standards.
Several VOCs and SVOCs were noted above laboratory detection limits in the results, but all are below
the EPA Region ill risk-based concentrations (RBCs) and Region IX preliminary remediation goals
(PROs) used by ADEM to determine the necessity of additional assessment. PAH presence was below
laboratory detection limits.

A minor presence of mercury was noted at very low levels in 2 soil samples and arsenic was noted in
several soil samples at low concentrations. The mercury presence is below the likely applicable
screening standards. The range of naturally occurring arsenic in soils Is 0.1 to 40 mg/kg. Chromium
presence was noted in several soil samples at values exceeding the ADEM initial screening levels.
These chromium values are considered to be low and very near the lower end of the range for naturally
occurring chromium (5 to 3,000 mglkg). Although both of these elements ·slightly exceed the ADBM
screening srandarda, it is not believed that there Is a reportiJ,lg obligation in place for these results. In
past conversations with ADEI'vi, they indicated that they prefer that all results be reported, although
there is no specific regulation requiring this in non-underground storage tank (UST} situations.
Groundwater
During advancement of the soil borings, groundwater was encountered at approximately 5 feet bgs on
the south parcel and at approximately 13 feet bgs (near top of bedrock) on the north parcel. Consistent
refusal on hard rock prior to .encountering groundwater at the north parcel limited the number of
groundwater samples that could be collected to four. Based upon field observations of the topography
and borings, shallow groundwater is expected to flow toward the south on the north parcel and toward
the west on the south parcel.
Metals analyses of the groundwater indicates fairly low concentrations of several merals present across
the 4 temporary wells (3 on south parcel and 1 on north parcel} sampled. Of these, oniy lead was found
at levels above current ADEM primary drinking water standarda. Total lead concentrations ranging
from 16 micrograms per liter (ug/L) to 33 ug/L were detected in the four groundwater sampling points.
Although these concentrations slightly exceed the ADEM primary drinking water standard of 1.5 ug!L,
it is not uncorrunon for similar levels to be detected from background lead concentrations in soils.
Vinyl chloride was detected at a concentration of 4 ug/L, which slightly exceeds the ADEM primary
drinking water limit of 2 ug/L. This sample was collected from TW-03, located along the west wall of
the main building on the south parceL No other VOCs were detected above the ADEM standards.
Based on past conversations and experience with ADEM, it is believed that they will most likely
consider any presence of a regulated compound exceeding drinking water standards in waters of the
State io be a release and therefore reportable to ADEM. It may be appropriate for legal counsel to
advise on potential release reporting obligations for these detections to the State.

ADEM currently only has published groundwater quality standards established for primary drinking
water. Non-potable groundwater sources are evaluated on a case-by-case basis using risk-based
methodologies to assess the potential for impacting sensitive receptors such as surface water or drinking
water supply wells. According to City Water Department, all residents and business are cOJmecled to
the City drinking water supply system. Furthermore, as there are no readily available records of any
drinking or other supply wells in the inuuediate area of the property, it is likely that less restrictive site
specific groundwater standards above the maximum detected concentrations can be applied for the
subject site. It is, however, likely that ADEM will request additional investigation to evaluate potential
source areas and extent of the compounds as well as confirm that grouodwater is not used locally.
GaiaTech has been requested to conduct additional groundwater sampling in this area to confirm the
previous vinyl chloride detection as well as evaluate tl1e potential source area and extent of
contamination, if present. .
Lexington, South Carolina
The following AOCs identified by GaiaTech during the ESA were addressed as part of the subsurface
sampling scope of work:
• Process wastewater from site operations is reported to have been previously discharged through
an on-site septic system. No documentation is available characterizing this wastewater prior to
discharge.
A total of 7 soil borings were installed and select soil samples from 4 of the 7 borings were analyzed by
a laboratory for VOCs, PAHs, and 8 RCRA metals plus zinc. Laboratory analyses indicates no VOCs
or PAHs present above laboratory detection limits. Based upon these results, nothing further is required
at lhls time. The analyses for metals indicate low metals presence, with a!! values falling within the
range of naturally-occurring concentrations. Based upon these results, nothing further is recommended
at this time.
Soil borings were advanced to a depth of approximately 16 feet below ground surface with no
appreciable groundwater being encountered during boring. No temporary wells were installed and no
groundwater samples were obtained. Based upon the soil results, nothing further is recommended at this
time.

The following AOCs identified by GaiaTech during the ESA were addressed as part of the subsurface
sampling scope of work:
• A fanner gasoline underground storage tank (UST) is reported to have been on-site for an
unknown number of years and is reported to have been removed in the late 1980s. No closure
information is available.
A total of 6 soil borings were installed and selec."! soil samples from 4 of the 6 borings were analyzed by
a laboratory for VOCs, total petroleum hydrocarbom-gasoline range organics (TPH-GRO), and lead.
Analyses indicate no VOCs and no TPH-GRO to be present above laboratory detection limits. The
analyses for lead indicate a limited presence of lead in the soil sampled. The EPA Engineering Forum
paper describing naturally-occurring inorganics lists average lead presence in soil to be 2 to 200 mg!kg.
The North Carolina Department of Environment and Natural Resources (NCDENR) regulatory levels
are an order of magnitude higher (8 to 10 times higher) than the results of this soil sampling and
therefore not considered as indicative of impact and no further investigation would appear to be
warranted.
Groundwater
Soil borings were created to a depth of approximately 16 feet below ground surface with no appreciable
groundwater being encountered during boring. No temporary wells were installed and no groundwater
samples were obtained. Based opon these results, nothing further is recommended at this time.

L 1 Site Desc!"iption and Background
TlH: site consists ot' rl1ree contiguous parccis rmaling 2.03 acres of land locaretl bcrwcen
i2'" Avenue NE anrl t 1'1' Avenue NE. Thesc parcels make up rt1e manufacmring area of the
site. ln audition ro thcsc parcds, a 0. 61 ·acre parking area is located across ll '" Avenue N f:
to the sornh of the manufaclUring portion of the sire. The northernmost parcel ot the
manufacturing portion of rhe silt: is occupied by a large manufacturing building includlug
an office area and t\vo >:;maller manufacmring buildings alo11g the wesH~rn property
houndary. The :muthern two parcels are occupied by a loading dock associated with rhe
nmmrfacruring building and two smaller builclings. Approximately 60:f of tht: area of the
manufacturing portion of tile site is occupied by buildings. The remainder consists of
asphalt and concret<:>paved parking and loatling areas and a small grassy mrct along the
norrtrern side of the building.
The sire is currently vacant and unused. From as early as 1956, the sire operatecl '" a
textile manufacturing facility. Hisroricaloccupants include Reaco Hosiery Mills, Madaris
Hosierv Mil!s. the EhLstic corporation. and Realspan Corrorarion. In the 1960s. an
amomotive repair business operated in one of the smaller buicdings locatecl to the south of
the manufacmring huilding. Regal, the most recent occupant ot' the site, manufacmred
elastic yam on sire from the 1960s until 1999 when manufacturing openltions on site
ceased.
Accnrtli ng to representatives of W or!utex, Regal utilize some hazardous chemicals in its
maimcnance proccsse~, De[ails regarding hi~torical openuion:-;, prior tt) Regal's. are not
known. As a result, there is a potential for impacts tn the site resulting l'rom historical on-
site o,xrations.
The surrounding rroperries consisted of prinmriJy commercial anti industrial propert!c~
from as early as tile 1950s. Two gasoline stations and a sdf-sen·e car wash have bnrtlerecl

GaiaTed1 comlucred a Phase 1 Environmemal Sire Assessmem (ESA) of the sire in
Nnvember 2001 that identified potential impacts ro the sire from the former underground
storl_ge tank { t;ST), hytlranlk litL hiswriclll textile manufacturing operations, and potential
impacts t'ronr leaking UST and lmnnlous waste generming fnciliries in the vicinity ol· the
sire.
Suh;;equent to GaiaTecll's Phase 1 ES.',, a Focused Pll,tse II hJYesrigarion was conducted b}
GaiaTedt in January 2UO.: to evaluate potentia! impacls in tile vicinity of tile former UST.
No evillenee of impact to soil was idcmiiiecL However, no groundwater sampk:s were
obraineu,
An lmpacl Review of rile sire was conducted by GaiaTeeh in February ::'.007 GaiaTeclt
evaluareu rile previous reports, as well as regulatory documents related to nearby UST
facilities including Viewmonr Ex,on and Servco, ench locmeu adjaeenl ro the west ,,f the
sire. This review com:lmled tllat t!lc Viewmom Exxon am! Servco facilities have had
releases vf petrokum products. ln allllirion, PCE and TC.E were observed in groundwater
collecred at the S.crvco facility.
In an effon to determine whether tile she lws been impacted by contaminants observed at
the adjacent property anli whether these com;uninanrs might have originated on site,
Gaia Tech targeted the in,·esrigation to evalume areas Liuwngrudiem and upgradiem of rhe
manul'acturing plant, A comparison of these results will aid in pinpniming the soun:e nf
potemial comaminams. It is possible that the PCE and TCE have multiple sources.

L3 Geology and Hydrogeology
According to tile Soil Sune" oj'Ca!ttH·ba Coumv, !Vonil Carolina, site soils are classiticJ
as Cecil Sandy Loam with 2 to 6 percent slopes. The Cecil series consists of well-drained
soil> on uplands. These soils formed in residuum from acidic rock, including grattite>gnciss
and granire. It is a well-drained soil on fairly smooth, bruud ridges and upbn<is. Typically.
the surface layer is dark grayish-brown and brown sandy loam approximately 7 inches
thick. The subsoil is approximately 43 inches !!tick and is dominantly red, firm day in the
upper part and red, friable clay loan! mnttled with brown in the lower pan. The
substratum. to a depth of approximately 75 inches, is mottled red and brown sanely loam.
During Gaia Tech's investigation, the subsurface materials typically encountered in the soil
borings cmtsisted of micaceous silty sands that were mottled with (red, black, and yellow)
clayey pockets and intersected by louse scams of weathered rock fragments. !n generaL
Gaia Tech observed severely weathered rock m depths ranging from approximately :!0 feet
to 30 feet below ground surface (bgsJ across the site. Less severely wc;:thered rock \\'as
encountered at depths ranging fwm approximately 30 to 40 feet bgs across the site. \Vi thin
the ol0--l5 fr bgs extent nf this investigation, competent rock was encoumered in the area
approximated hy the ;;nuthwestem comer of the plant at approximately 35 feet bg~.
Ground\Vater was ob'jt~n't!d Ht th:prhs ranging from appro~imately 30 to 37 feet hg.,
throughout the site. Elased on measurcmems col leered during the tield component of tiJis
:lssessmenl. groundwater at the site is tlowing in a soutlnvcster~y direcrion.
