EXECUTIVE SUMMARY

This report presents the findings of a Phase II environmental site assessment (ESA) conducted at the Rock

Hill Bleachery (RHB) Targeted Brownfields Assessment (TBA) site, under Contract Number (No.) EP-

W-05-054, Technical Direction Document (TDD) No. TTEMI-05-003-0151. This Phase II ESA was

conducted by the Tetra Tech Superfund Technical Assessment and Response Team (START) on behalf of

the U.S. Environmental Protection Agency (EPA).

In 1929, the Rock Hill Printing and Finishing Company (also known as the Bleachery) began operations

at 420 West White Street in Rock Hill, York County, South Carolina. RHB produced bleached and dyed

cotton and polyester blend fabrics until 1998, when all operations ceased. During operations, the site

included a main manufacturing building (main building), which was a combination of five contiguous

buildings and numerous separate buildings, generally located on the north side of the main building. The

site also included a coal- and oil-fired boiler house, a water treatment plant, a 2 million-gallon reservoir,

exterior bulk storage tanks, a foundry, a chrome plating room, a metal wash room, a print roller room, a

dye mixing room, a dye creations room, a bleachery, a boil-off room, a machine shop, storage and

maintenance buildings, guard houses, offices, and warehouses. Most of the original buildings and

subsequent expansion buildings were demolished between 2010 and 2011, leaving only an office

building, boiler house, water treatment plant, pump house, guard house, and reservoir.

In May 2010, Irminger Consulting, Inc (ICI), on behalf of the City of Rock Hill, conducted a Phase I ESA

at the RHB property. The Phase I ESA consisted of a records review; site reconnaissance; and interviews

with personnel knowledgeable about the site; and preparation of the Phase I ESA report.

Based on the Phase I ESA, between October 2010 and April 2011, ICI conducted an interim Phase II ESA

to build on existing data and fill data gaps from previous assessment and remediation activities. The

interim Phase II ESA was conducted concurrent with demolition activities. The goal of the interim Phase

II ESA was to provide a thorough understanding of the environmental risks, allowing safe re-development

of the RHB property.

In March 2011, Crossroads Environmental, LLC, completed an asbestos inspection, including asbestos

sampling, in the four-story office building and water treatment plant. Asbestos-containing materials,

including floor tiles, pipe insulation, hard joint insulation, and transite panels, were identified in both

buildings in conditions ranging from good to significantly damaged. The types of asbestos detected were

chrysotile and amosite.



In September 2012, Tetra Tech mobilized to the RHB site, conducted an initial assessment of the

property, and identified recognized environmental conditions (REC) and potential RECs that would form

the basis for the Phase II ESA sampling strategy. The following were identified as RECs or potential

RECs:

Six underground storage tanks (USTs) were closed in place (contents pumped out and UST filledwith a solid foam material). Specifically, three USTs contained varsol, one UST contained diesel,and two USTs contained gasoline. Details regarding the closure of these USTs (includingpossible sampling) are not available. Therefore, it is not known whether the USTs leaked into thesurrounding soil before closure.

Three vaults that contained oil and water were closed in place. Details regarding closure of thesevaults (including possible sampling) are not available. Therefore, it is not known whether thevaults leaked into the surrounding soil before closure.

The sump that contained used oil was closed in place during demolition activities. Detailsregarding closure of the sump (including possible sampling) are not available. Therefore, it is notknown whether the sump leaked into the surrounding soil before closure.

The flooded basement of the boiler house was identified as a potential REC. The origin of thewater is unknown.

The former chrome plating area was identified as a REC because soils in this area havehistorically contained high levels of metals and semivolatile organic compounds (SVOC).

In most soil samples collected during the interim Phase II ESA, SVOCs — such asbenzo(a)anthracene, benzo(a)pyrene, and indeno(1,2,3-cd)pyrene — were not detected; however,the reporting limits for these analytes were above the EPA Regional Screening Levels (RSL) forindustrial soil in many samples, thereby precluding the non-detects from being definitive. Soilson the property were identified as a potential REC because it is unknown whether SVOCs arepresent above EPA RSLs for industrial soil.

During the week of October 1, 2012, a Tetra Tech subcontractor, GEL Geophysics, LLC (GEL), mapped

all underground structures, objects, and utilities at the RHB property in preparation for the Phase II ESA

sampling event. Several areas were identified as potentially containing buried objects, including the areas

where known underground structures, such as vaults, sumps, and USTs, are located. Tetra Tech used the

map of subsurface features generated by GEL to navigate around buried objects during Phase II ESA

sampling activities.

During the week of October 29, 2012, Tetra Tech conducted initial Phase II ESA activities at the RHB

property. The purpose of the Phase II ESA was to assess the presence and nature of contamination, if

any, and to collect data to formulate the basis for an Analysis of Brownfields Cleanup Alternatives.

RECs, possible RECs, and other environmental hazards identified during the Phase I and interim Phase II

ESA reports, as well as during the site visit, were targeted for assessment. Surface and subsurface soil,



groundwater, surface water, and sediment were sampled to address these conditions. The results are

summarized below:

Surface soil samples collected in the former chrome plating area contained SVOCs and metals at

concentrations exceeding EPA RSLs for industrial soil. Subsurface soil samples contained arsenic at

concentrations exceeding its EPA RSL for industrial soil. In addition, butylbenzylphthalate was detected

in one surface soil sample at an elevated concentration. Subsurface soil samples contained arsenic,

chromium, lead, mercury, and zinc, among others, at elevated concentrations.

Subsurface soil samples collected from the proposed grassy area contained benzo(a)anthracene,

benzo(a)pyrene, benzo(b)fluoranthene, dibenz(a,h)anthracene, and indeno(1,2,3-cd)pyrene at

concentrations that exceeded their EPA RSLs for industrial soil. In addition, surface and subsurface soil

samples contained elevated concentrations of SVOCs.

Composite subsurface soil samples were collected from 18 grids across the property. Of those, 11 grids

contained SVOCs at concentrations exceeding their EPA RSLs for industrial soil and nine grids contained

arsenic at concentrations exceeding its EPA RSL for industrial soil. Several grids also contained elevated

concentrations of SVOCs and metals.

Subsurface soil samples collected around the diesel UST contained diesel range organics (DRO) and lead.

Subsurface soil samples collected around the two gasoline USTs contained gasoline range organics

(GRO) and lead. Subsurface soil samples collected around the used oil sump contained DRO, GRO, and

lead. Subsurface soil samples collected around the three oil and water vaults contained DRO and lead.

(GRO was not detected.) All of the subsurface soil samples collected around the varsol USTs contained

varsol range organics (VRO). Based on the analytical results, it appears that the diesel UST, the used oil

sump, and the varsol USTs leaked hazardous substances into the surrounding soil.

Of the six monitoring wells sampled, one well contained volatile organic compounds (VOC) exceeding

EPA maximum contaminant levels (MCL). Specifically, monitoring well MW-13, located near the

former machine shop in the office building, contained tetrachloroethene (PCE) and trichloroethene (TCE)

at concentrations exceeding their EPA MCL of 5.0 µg/L.

Surface water samples collected from the unnamed tributary of Wildcat Creek contained zinc at

concentrations exceeding its freshwater acute and freshwater chronic EPA Region 4 surface water

screening values (SWSV). Sediment samples collected from the unnamed tributary of Wildcat Creek

contained PCB-1248 at a concentration exceeding the EPA Region 4 sediment screening value (SSV) for



total polychlorinated biphenyls (PCB). Sediment samples also contained arsenic, lead, and zinc at

concentrations exceeding their EPA Region 4 SSVs.

The City of Rock Hill requested that EPA further investigate seven of the areas identified during the

geophysical survey to determine whether previously unidentified buried objects, such as USTs, were

present. In November 2012, Tetra Tech returned to the site to oversee trenching in the seven areas

requested by the City of Rock Hill. During trenching, Tetra Tech did not observe any USTs or other

underground structures in the seven areas of concern. However, large pieces of construction debris, such

as sections of brick walls and concrete foundations, were observed in each of the seven areas. During

excavation in the area of the former elevator vault located in the southeastern portion of the site, a strong

used oil odor was noted at about 8 feet below ground surface (bgs). In addition, a strong gasoline odor

was noted in the former transformer area at around 6 feet bgs. All of the trenches were backfilled prior to

demobilization.

Based on the results of trenching, EPA requested Tetra Tech return to the site to collect samples in the

former elevator vault and former transformer areas. In December 2012, Tetra Tech collected two grab

soil samples from the former elevator vault at 8 feet bgs. The subsurface soil samples contained, PCB-

1254, anthracene, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, chrysene, fluoranthene,

indeno(1,2,3-cd)pyrene, phenanthrene, and pyrene. Benzo(a)anthracene, benzo(a)pyrene,

benzo(b)fluoranthene, and indeno(1,2,3-cd)pyrene were detected at concentrations exceeding their EPA

RSLs for industrial soil.

Four soil borings were advanced north, east, south, and west of the trench that contained the gasoline odor

in the former transformer area. Free product was observed in the northern and southern soil borings at 4.5

to 5.5 feet bgs and 5.5 to 6.5 feet bgs. A strong gasoline odor was also noted. The eastern and western

soil borings did not have an odor and did not contain free product; therefore, samples were not collected

from these borings. Grab subsurface soil samples were collected from the northern and southern soil

borings at the depths containing free product. The samples contained GRO, ethylbenzene,

isopropylbenzene, methylcyclohexane, and arsenic. PCBs were not detected in either sample.

As a result of the presence of gasoline free product in the former transformer area during the December

2012 additional soil sampling event, Tetra Tech was tasked by EPA to delineate the lateral and vertical

extent of the gasoline contamination. On January 10, 2013, soil borings were advanced radially from the

trench at 20-foot intervals. Soil borings were advanced down to 15 feet bgs and were screened

continuously for VOCs using a photoionization detector (PID). Tetra Tech continued to advance borings

radially until VOCs were not detected with the PID. Based on PID readings, gasoline free product



extends laterally about 20 feet north of the trench and about 80 feet south of the trench. Vertically, the

free product extends down to 15 feet bgs.

Tetra Tech collected six grab subsurface soil samples with a mixture of high, mid-level, and low PID

readings to confirm the PID screening. The samples contained GRO, ethylbenzene, isopropylbenzene,

methylcyclohexane, and naphthalene. Naphthalene exceeded its EPA RSL of 18,000 µg/kg for industrial

soil in one subsurface soil sample. PCBs were not detected in soil samples collected from the former

transformer area.

2.0 SITE BACKGROUND

This section discusses the site location and description, and provides a brief summary of previous

investigations conducted at the site. The full investigation of historical property uses, a detailed

description of on-site buildings and structures, and previous investigations can be found in the Phase I

report (Ref. 7).

2.1 SITE LOCATION AND DESCRIPTION

The RHB property, located at 420 West White Street in Rock Hill, York County, South Carolina, is

approximately 23.4 acres and is surrounded by residential, commercial, and industrial areas of Rock Hill

(see Figure 1 in Appendix A). The property is bordered to the north by Stewart Avenue and residential



properties beyond, to the east by railroad tracks and residential and commercial properties beyond, to the

south by an industrial property, and to the west by West White Street and a cemetery beyond (see Figure

2 in Appendix A). The geographic coordinates for the RHB site, as measured from the approximate

center of the property, are latitude 34.933075 degrees north and longitude 81.030849 degrees west.

In 1929, the Rock Hill Printing and Finishing Company (also known as the Bleachery), owned by Springs

Industries, began operations at 420 West White Street (Ref. 8). RHB produced bleached and dyed cotton

and polyester blend fabrics until 1998, when all operations ceased. During operations, the facility

included a main manufacturing building (main building), which was a combination of five contiguous

buildings and numerous separate buildings, generally located on the north side of the main building. The

facility also included a coal- and oil-fired boiler house, a water treatment plant, a 2 million-gallon

reservoir, exterior bulk storage tanks, a foundry, a chrome plating room, a metal wash room, a print roller

room, a dye mixing room, a dye creations room, a bleachery, a boil-off room, a machine shop, storage and

maintenance buildings, guard houses, offices, and warehouses (see Figure 2 in Appendix A) (Ref. 7).

In the 1930s, the water treatment plant was constructed on the northeastern corner of the property. Raw

water pumped from the Catawba River was treated in the water treatment plant by a succession of sand

filters, clarifiers, and pH adjustment. Effluent from the water treatment plant was stored in the 2 million-

gallon on-site reservoir. The reservoir water continues to be treated in the on-site water treatment plant.

The coal- and oil-fired boiler house was used to heat the water for use in the textile bleaching and dying

processes. In 1951, the boiler house consumed about 350 tons of coal per day. In 1955, the coal plant

was expanded, and in the 1990s, the plant’s fuel sources included fuel oil and propane, which were

converted to natural gas on site (Ref. 7).

According to City of Rock Hill personnel, the basement of the boiler house has been flooding since it was

built. It is believed that the boiler house was built on top of a natural spring, but this information has not

been confirmed. During operations, the basement water was continuously pumped out so that personnel

could access the basement for maintenance and to clean the boilers. Since operations ceased, the

basement has been periodically pumped out by the City of Rock Hill, but for the most part remains

flooded (Ref. 7). In 2012, oil was spilled inside the boiler house during unauthorized removal of some of

the piping. Irminger Consulting, Inc (ICI), a subcontractor of the City of Rock Hill, cleaned up the spill.

It is not known whether any of the oil was released into the basement water.

During the 1990s and early 2000s, an electric substation operated by Duke Power Co. (to serve the

Bleachery) was located on the north-central portion of the RHB property. Once operations at the facility



ceased, the substation was removed from the site. This area is now referred to as the former transformer

area (Refs. 7; 9).

The facility also maintained several vaults, sumps, and underground storage tanks (UST), including three

USTs (two 10,000 gallon and one 12,000 gallon) that contained varsol, one 10,000-gallon UST that

contained diesel, and two 500-gallon USTs that contained gasoline. The diesel UST, located near the

boiler house, was used to heat the fuel oil. Varsol is a solvent most commonly used for cleaning and

degreasing surfaces, rollers, brushes, and tools (Ref. 10). The varsol USTs were located near the metal

wash room and the print roller room; therefore, it was most likely used by RHB to clean the rollers and

brushes. After operations ceased at the facility, the contents of all vaults, sumps, and USTs were pumped

out and the structures filled with either a solid foam material or sand, closing them in place.

Storm drains are located throughout the property. The storm drains generally flow by gravity toward the

north and then toward the west, where a large-diameter conduit conveys the stormwater to an unnamed

tributary of Wildcat Creek, located about 500 feet northwest of the RHB property (Ref. 7).

York Printing and Finishing, Inc. operated on the property between 1998 and 2003 (Ref. 8). In 2003, the

property was purchased by Environmental Land Augmentation, Inc. (ELA), which used a small portion of

the property for offices and storage. In July 2009, the main building was damaged by a fire. In

November 2009, ELA moved its offices to another location, and ownership of the property was

transferred to the City of Rock Hill. Most of the original buildings and subsequent expansion buildings

were demolished between 2010 and 2011, leaving only an office building (former location of the boil-off

room, machine shop, dye creations room, and offices), boiler house, water treatment plant, pump house,

guard house, and reservoir (Ref. 11) (see Figure 2 in Appendix A). The City of Rock Hill’s future plans

include dividing the property into three separate parcels (northern, central, and southern) for development.

The City of Rock Hill plans to sell or lease the parcel that contains the office building (the southern

parcel), which will also include a parking lot and a grassy area. Plans for the other two parcels have not

yet been finalized. Currently, there are no groundwater restrictions in place on the property.

2.2 PREVIOUS INVESTIGATIONS

The RHB property has been the subject of several environmental studies. Nineteen areas of concern

(AOC) were investigated by Dames and Moore Group in September 1998. Initial assessment activities at

the 19 AOCs resulted in seven AOCs requiring additional assessment and remediation. All of the AOCs



have received regulatory closure by the South Carolina Department of Health and Environmental Control

(SC DHEC) after full assessment and remediation (Ref. 7).

In May 2010, ICI, on behalf of the City of Rock Hill, conducted a Phase I ESA at the RHB property. The

Phase I ESA consisted of a review of site records; a site reconnaissance; interviews with site personnel

and federal, state, and local government representatives; and preparation of the Phase I ESA report.

Based on the review of site records, the site reconnaissance, and the interviews, ICI identified a total of 22

AOCs. It is not known whether any of the 19 AOCs identified by Dames and Moore Group overlap with

ICI’s 22 AOCs. Of the 22 AOCs, six were RECs or potential RECs associated with the site, including (1)

soil contamination in the former chrome plating area, (2) oil staining from a damaged hydraulic elevator

machine in the main building, (3) a former dye house in the main building, (4) clay sanitary sewer pipes

beneath the main building, and (5) chlorinated solvent and (6) semivolatile organic compound (SVOC)

contamination in groundwater samples collected from on-site monitoring wells (Ref. 7).

Between October 2010 and April 2011, as a result of the Phase 1 ESA, ICI conducted an interim Phase II

ESA to build on existing data and fill data gaps from previous assessment and remediation activities. The

interim Phase II ESA was conducted concurrent with demolition activities. The goal of the interim Phase

II ESA was to provide a thorough understanding of the environmental risks, allowing safe re-development

of the RHB property (Ref. 11).

A total of 107 surface soil samples and five water samples were collected. Most surface soil (0 to 6

inches below ground surface [bgs]) samples contained arsenic and vanadium above their EPA Regional

Screening Levels (RSLs) for industrial soil. SVOCs, such as benzo(a)anthracene, benzo(a)pyrene, and

indeno(1,2,3-cd)pyrene, were not detected in most soil samples. However, the reporting limits for these

analytes were above the EPA RSLs for industrial soil in many samples, thereby precluding the non-

detects from being definitive (Ref. 11).

Two water samples were collected from standing water inside two former vaults (BP-MW-01 and BP-

MW-02), two water samples were collected from existing on-site monitoring wells (BP-MW-03 and BP-

MW-04), and one water sample was collected from a floor drain beneath the office building (BP-MW-

05). The water samples collected from the former vaults contained methylene chloride (at 661J

[estimated] micrograms per liter [µg/L]), arsenic (up to 48.1 µg/L), chromium (up to 93.8 µg/L), lead (up

to 220 µg/L), and mercury (up to 3.1 µg/L), among others. Groundwater samples contained chromium

(up to 2.9J µg/L), manganese (up to 854 µg/L), and mercury (up to 0.19J µg/L), among others. The water

sample collected from the floor drain contained 1,1-dichloroethane (at 7.9 µg/L), 1,1,1-trichloroethane (at



3.3 µg/L), arsenic (at 2.7J µg/L), chromium (at 629 µg/L), lead (at 1,340 µg/L), manganese (at 1,660

µg/L), and mercury (at 3.6 µg/L) (Ref. 11).

In March 2011, Crossroads Environmental, LLC, completed an asbestos inspection, including asbestos

sampling, in the four-story office building and water treatment plant. The inspection was conducted by an

accredited inspector and included collection of 122 bulk samples, which were submitted to an accredited

laboratory for analysis. Asbestos-containing materials, including floor tiles, pipe insulation, hard joint

insulation, and transite panels, were identified in both buildings in conditions ranging from good to

significantly damaged. The types of asbestos detected were chrysotile (ranging from 3 percent to 15

percent) and amosite (10 percent) (Ref. 12).

3.0 SITE VISIT AND GEOPHYSICAL SURVEY

The RECs and potential RECs presented in the May 2010 Phase I ESA report were identified before

demolition occurred. In September 2012, Tetra Tech mobilized to the RHB site to conduct an initial

assessment of the property and to identify RECs and potential RECs to form the basis for the Phase II

ESA sampling strategy. Tetra Tech returned to the RHB site during the week of October 1, 2012, to

conduct a geophysical survey of the property.

3.1 RECOGNIZED ENVIRONMENTAL CONDITIONS

RECs and potential RECs associated with the RHB property were identified based on previous ESAs, by

visual observation during the site visit conducted on September 19, 2012, and through historical site

knowledge provided by City of Rock Hill personnel. The following were identified as RECs or potential

RECs:

Six USTs were closed in place (contents pumped out and UST filled with a solid foam material).Specifically, one 12,000-gallon and two 10,000-gallon USTs contained varsol, one 10,000-gallonUST contained diesel, and two 500-gallon USTs contained gasoline. Details regarding closure ofthese USTs (including possible sampling) are not available. Therefore, it is not known whetherthe USTs leaked into the surrounding soil before closure.

Three vaults were closed in place. The vaults contained oil and water prior to closure. Detailsregarding closure of these vaults (including possible sampling) are not available. Therefore, it isnot known whether the vaults leaked into the surrounding soil before closure.

The sump closed in place during demolition was identified as a potential REC. The sumpcontained used oil prior to closure. Details regarding closure of the sump (including possible



sampling) are not available. Therefore, it is not known whether the sump leaked into thesurrounding soil before closure.

The flooded basement of the boiler house was identified as a potential REC. The origin of thewater is unknown.

The former chrome plating area was identified as a REC because soils in this area havehistorically contained high levels of metals and SVOCs.

In most soil samples collected during the interim Phase II ESA, SVOCs — such asbenzo(a)anthracene, benzo(a)pyrene, and indeno(1,2,3-cd)pyrene — were not detected; however,the reporting limits for these analytes were above the EPA RSLs for industrial soil in manysamples, thereby precluding the non-detects from being definitive. Soils on the property wereidentified as a potential REC because it is unknown whether SVOCs are present above EPARSLs for industrial soil.

3.2 GEOPHYSICAL SURVEY

During the week of October 1, 2012, a Tetra Tech subcontractor, GEL Geophysics, LLC (GEL), mapped

all underground structures, objects, and utilities at the RHB property in preparation for the Phase II ESA

sampling event. To complete the survey, GEL used ground penetrating radar (GPR), electromagnetic

(EM), and conductivity instruments. Several areas were identified as potentially containing buried

objects, including the areas where known underground structures, such as vaults, sumps, and USTs, are

located. Tetra Tech used the map of subsurface features generated by GEL to navigate around buried

objects during Phase II ESA sampling. The GEL geophysical survey report is presented in Attachment 1.

4.0 INITIAL PHASE II ESA ACTIVITIES

The purpose of the Phase II ESA sampling event was to assess the presence and nature of contamination,

if any, and to collect data to formulate the basis for an Analysis of Brownfields Cleanup Alternatives.

RECs, potential RECs, and other environmental hazards identified during the ICI Phase I and interim

Phase II ESAs, as well as during the Tetra Tech site visit, were targeted for assessment. Surface and

subsurface soil, groundwater, surface water, and sediment were sampled to address these conditions.

Figures 3A and 3B in Appendix A depict the sampling locations. Tables summarizing analytical results

are contained in Appendix B. The field notes are provided in Appendix C.

4.1 SAMPLING METHODOLOGY AND ANALYSIS

All sampling was conducted in accordance with applicable EPA Region 4 SESD FBQSTPs, unless

otherwise specifically noted (Ref. 2).



4.1.1 Soil Sampling

Soil sampling locations were selected to either target specific RECs identified in the ICI Phase I ESA

report, ICI interim Phase II ESA report, and during the September 2012 site visit, or to assess a broad

spectrum of possible contaminants that could be migrating off site. A track-mounted direct-push

technology (DPT) drill rig was used to collect most of the soil samples. The rig advanced steel drill rods

with cellulose acetate butyrate liners to specific depths and withdrew soil samples.

A total of 24 grab subsurface soil samples were collected from areas around known underground

structures (USTs, vaults, and sumps) on the property to evaluate whether any of the underground

structures leaked prior to closure. The estimated capacities of the USTs and the dimensions of the vaults

and sumps were provided by ICI. The diameter of each of the USTs was calculated based the capacity,

from which the bottom depth of each UST was estimated. The soil borings collected from these areas

were screened in the field for volatile organic compounds (VOC) with a photoionization detector (PID).

Grab soil samples were collected from depths with the highest PID readings. If the PID did not detect

VOCs in a soil boring, then a soil sample was collected from the top of the water table (generally between

10 and 15 feet bgs). The bottom depth of each subsurface soil sample was included at the end of the

sample ID in parentheses. The analytical suite for each sample was chosen based on the former contents

of the UST, vault, or sump. Specifically, six soil samples were collected between 4 and 20 feet bgs in the

vicinity of the varsol USTs and were analyzed for varsol range organics (VRO). Four soil samples were

collected between 2 and 11 feet bgs from in the vicinity of the gasoline USTs and were analyzed for

gasoline range organics (GRO). Three soil samples were collected between 2 and 6 feet bgs in the

vicinity of the diesel UST and were analyzed for diesel range organics (DRO). Selected soil samples

collected from the UST areas were also analyzed for lead. Soil samples collected around the used oil

sump and oil and water vaults were analyzed for DRO, GRO, polychlorinated biphenyls (PCB), and lead

(see Figure 3B in Appendix A).

The former chrome plating area was divided into two grids. One three-point composite surface soil

sample (0 to 1 foot bgs) was collected from each grid. Three grab subsurface soil samples (2 to 4 feet

bgs) were also collected from each grid. The surface soil samples were analyzed for VOCs, SVOCs, and

metals. The subsurface soil samples were analyzed for VOCs and metals.

The grassy area that will be included on the proposed subdivided southern parcel that contains the office

building was divided into three grids. Five-point composite surface (0 to 1 foot bgs) and subsurface (1.5



to 2 feet bgs) soil samples were collected from each grid. The surface and subsurface soil samples were

analyzed for SVOCs and metals.

In addition, the portion of the RHB property between the proposed grassy area and the water reservoir

was divided into sixteen 100-foot by 100-foot grids and two 100-foot by 200-foot grids. One five-point

composite subsurface soil (1.5 to 2 feet bgs) sample was collected from each grid and analyzed for

SVOCs and metals. The portion of the property located along West White Street was not sampled.

Historically, this area was a paved parking lot and will likely be paved in the future once the site is

repurposed. After the initial Phase II ESA sampling was completed, it was discovered that an electrical

substation was previously located on this portion of the property (currently referred to as the former

transformer area). See Section 6.3 for additional information. A parking lot is also planned for the area

east of the office building; therefore, this area was not sampled (see Figures 2 and 3A in Appendix A).

All soil sampling was conducted in accordance with the EPA Region 4 SESD FBQSTP for Soil Sampling

(SESDPROC-300-R2), December 2011 (Ref. 2).

4.1.2 Groundwater Sampling

Between 1998 and 2006, 21 monitoring wells were installed and sampled on the RHB property. Six

monitoring wells historically contained VOCs at concentrations exceeding their detection limits. These

monitoring wells (MW-11, MW-13, MW-14, MW-15, MW-17, and MW-18) were sampled during the

Phase II ESA and the samples were analyzed for VOCs.

All groundwater sampling was conducted in accordance with the EPA Region 4 SESD FBQSTP for

Groundwater Sampling (SESDPROC-301-R2), October 2011 (Ref. 2).

4.1.3 Surface Water, Sediment, and Basement Water Sampling

During operations, the storm drains on the property flowed to the north and then to the west where a

conduit conveyed the water to an unnamed tributary of Wildcat Creek. Surface water and sediment

samples were collected to determine whether past RHB operations contaminated the unnamed tributary of

Wildcat Creek. Specifically, one surface water sample (RHB-SW-01) and one sediment sample (RHB-

SD-01) were collected near the conduit outfall, and two surface water samples (RHB-SW-02 and RHB-

SW-02-DUP) and two sediment samples (RHB-SD-02 and RHB-SD-02-DUP) were collected



downstream of the outfall (see Figure 3A in Appendix A). Surface water and sediment samples were

analyzed for VOCs, SVOCs, GRO, DRO, VRO, PCBs, and metals.

According to City of Rock Hill personnel, the basement of the boiler house has been flooding since it was

built. It is believed that the boiler house was built on top of a natural spring, but this information has not

been confirmed. During operations, the basement water was continuously pumped out so that personnel

could access the basement for maintenance and to clean the boilers. Since operations ceased, the

basement has been periodically pumped out by the City of Rock Hill, but for the most part remains

flooded. In 2012, oil was spilled inside the boiler house during unauthorized removal of some of the

piping. ICI cleaned up the spill; however, it is not known whether any of the oil was released into the

basement water. A sample of the basement water was collected during the Phase II ESA sampling event

and analyzed for VOCs, SVOCs, PCBs, and metals.

Surface water samples were collected in accordance with the EPA Region 4 SESD FBQSTP for Surface

Water Sampling (SESDPROC-201-R1), November 2007, and sediment samples were collected in

accordance with the EPA Region 4 SESD FBQSTP for Sediment Sampling (SESDPROC-200-R2),

September 2010 (Ref. 2).

4.2 ANALYTICAL SUPPORT AND METHODOLOGY

Tetra Tech procured Pace Analytical Services, Inc. (Pace), located in Huntersville, North Carolina, to

analyze the samples. After each day of sampling, Tetra Tech relinquished samples to a Pace courier for

delivery to the laboratory. The samples were analyzed in accordance with the following EPA SW-846

methods: VOCs by Method 8260B; SVOCs by Method 8270D; PCBs by Method 8082A; GRO and DRO

by Method 8015C; and metals by Methods 6010C, 7471B (mercury soil), and 7470A (mercury aqueous).

For the VRO analysis, Pace subcontracted SGS Analytical Perspectives (SGS) in Wilmington, North

Carolina. SGS analyzed samples for VRO in accordance with EPA SW-846 Method 8015C (modified)

(Ref. 4).

Level IV data packages meeting the standards of the EPA CLP were requested from Pace, including case

narratives, chain-of-custody forms, sample results, QC summary forms, and the raw data. A 15-day

turnaround time for final data packages was requested for the analytical results of all samples submitted to

the laboratory for analysis. The analytical data packages, as received from the laboratory, are provided in

Appendix E.



After the data packages were received from the laboratory, Tetra Tech reviewed them for completeness

and conducted Stage 2A (cursory) data validation. The data validation process included a random

QA/QC comparison between the data listed in the electronic data deliverable and the electronic portable

document format copy of the analytical data package. Analytical results were validated in accordance

with the associated EPA SW-846 methods (Ref. 4); the EPA NFGs for Superfund Organic Methods Data

Review, EPA540-R-08-01, June 2008 (Ref. 5); and the EPA NFGs for Inorganic Superfund Data Review,

EPA 540-R-10-011, January 2010 (Ref. 6). The Tetra Tech data validation reports are provided in

Appendix F.

4.3 ANALYTICAL DATA QUALITY AND DATA QUALIFIERS

The text and analytical data tables presented in this report provide some of the results of organic and

inorganic parameters as qualified with a “J,” “J-,” “J+,” “U,” or “UJ.” The “J” notation indicates that the

analyte was positively identified; however, the reported value is an estimate. “J” qualified parameters

may also include a “+” or “-,” indicating either a high or a low bias. The “U” notation indicates that the

analyte was analyzed for, but not detected; the number reported is the laboratory-derived reporting limit

(RL) for the constituent in that sample. The “UJ” notation indicates that the analyte was analyzed for, but

was not detected above the laboratory-derived RL, which is considered approximate as a result of

deficiencies in one or more quality control criteria. The concentration of an analyte is considered

elevated if the concentration is greater than or equal to three times the background concentration or

greater than or equal to the sample-specific and analyte-specific RL, if not detected in the background

sample. The complete set of analytical data as received from the laboratory is provided in Appendix E,

and the Tetra Tech data validation reports are contained in Appendix F.

4.4 DEVIATIONS FROM THE QUALITY ASSURANCE PROJECT PLAN

Two sampling locations surrounding the two 500-gallon gasoline USTs were offset because ofsurface obstructions (see Figure 3B in Appendix A and page C-28 of Appendix C).

A road ran through Grids 3 and 8; therefore, only the northeastern unpaved portions of these gridswere sampled.

Grid 6, which contains the diesel UST, was completely covered with concrete; therefore, the gridwas not sampled.

Purge water that resulted from sampling the six on-site monitoring wells was contained in a 55-gallon drum. A water sample was collected from the drum and was analyzed for VOCs. Thesample did not contain VOCs above their maximum contaminant levels (MCLs) or regulatorylimits; therefore, the purge water was poured into the on-site reservoir. The reservoir watercontinues to be treated in the on-site water treatment plant.



5.0 INITIAL PHASE II ESA SAMPLING ANALYTICAL RESULTS

The following sections present a summary of analytical results for samples collected during the initial

Phase II ESA investigation conducted during the week of October 29, 2012. The discussion addresses

only the hazardous constituents associated with site operations and the hazardous constituents that may

pose a threat to human health or the environment. The sections will focus on results that are elevated and

exceed certain EPA guidance values for the particular medium and contaminant. EPA guidance values

include RSLs for industrial soil (Ref. 13), MCLs for groundwater (Ref. 14), EPA Region 4 surface water

screening values (SWSV) for surface water (Ref. 15), and EPA Region 4 sediment screening values

(SSV) for sediment (Ref. 16). No EPA or SC DHEC comparison criteria are currently available for GRO,

DRO, or VRO. The boiler house basement water sample was not compared to EPA guidance values.

Figures 3A and 3B in Appendix A depict the sampling locations, and a complete summary of analytical

data is presented in Appendix B, Tables 1 through 7.

5.1 FORMER CHROME PLATING AREA SAMPLING RESULTS

Composite surface soil samples RHB-CR-G1-SF and RHB-CR-G2-SF collected from 0 to 1 foot bgs in

the former chrome plating area contained benzo(a)pyrene (521 micrograms per kilogram [µg/kg] and 495

µg/kg) and arsenic (1.6 milligrams per kilogram [mg/kg] and 2.0 mg/kg) at concentrations meeting or

exceeding their EPA RSLs for industrial soil. Composite surface soil sample RHB-CR-G2-SF also

contained butylbenzylphthalate (645 mg/kg) at an elevated concentration. Grab subsurface soil (2 to 4

feet bgs) samples (RHB-CR-G1-SB-02-(4′), RHB-CR-G1-SB-03-(4′), and RHB-CR-G2-SB-01-(4′)) also

contained arsenic above its EPA RSL for industrial soil of 1.6 mg/kg (Ref. 13). Subsurface soil samples

contained arsenic, chromium, lead, mercury, and zinc, among others, at elevated concentrations. See

Figure 3A in Appendix A for the former chrome plating area sampling locations and Tables 1 and 3 in

Appendix B for a complete summary of the former chrome plating area sampling analytical results.

5.2 PROPOSED GRASSY AREA SAMPLING RESULTS

The proposed grassy area was divided into three grids. Composite surface soil (0 to 1 foot bgs) sample

RHB-GRA-G3-SF-DUP contained benzo(a)pyrene at 393 µg/kg, which exceeds its EPA RSL for

industrial soil of 210 µg/kg. Grab subsurface soil (1.5 to 2 feet bgs) samples contained

benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, dibenz(a,h)anthracene, and indeno(1,2,3-

cd)pyrene at concentrations that exceeded their EPA industrial RSLs (Ref. 13). In addition, grab

subsurface soil samples contained elevated concentrations of anthracene (up to 2,050J µg/kg),



benzo(a)anthracene (up to 3,820 µg/kg), benzo(a)pyrene (up to 3,800 µg/kg), benzo(b)fluoranthene (up to

3,020 µg/kg), carbazole (up to 629 µg/kg), chrysene (up to 4,060 µg/kg), dibenz(a,h)anthracene (up to

1,080 µg/kg), fluoranthene (up to 10,600 µg/kg), fluorene (up to 949J µg/kg), indeno(1,2,3-cd)pyrene (up

to 2,220 µg/kg), naphthalene (439 µg/kg), phenanthrene (up to 7,470J µg/kg), and pyrene (up to 7,580

µg/kg). See Figure 3A in Appendix A for the proposed grassy area sampling locations and Tables 1 and 2

in Appendix B for a complete summary of the proposed grassy area sampling analytical results.

5.3 GRID SAMPLING RESULTS

Composite subsurface soil (1 to 1.5 feet bgs) samples were collected from 18 grids across the RHB

property. Grid samples contained benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene,

dibenz(a,h)anthracene, indeno(1,2,3-cd)pyrene, and arsenic at concentrations exceeding their EPA RSLs

for industrial soil (Ref. 13). Several grids, including Grids 1 (located southeast of the water reservoir), 10

(located in the former metal washroom area), 13 (located in the print roller room area), 16 (located east of

the dryers and dye mixing room), and 19 (located in the bleachery area), among others, contained

elevated concentrations of SVOCs and metals (see Figures 2, 3A, and 3B in Appendix A and Table 2 in

Appendix B). Grid 10, located in the former metal washroom area, contained the highest concentrations

of SVOCs, including anthracene (18,500 µg/kg), benzo(a)anthracene (25,900 µg/kg), benzo(a)pyrene

(21,600 µg/kg), benzo(b)fluoranthene (18,900 µg/kg), benzo(k)fluoranthene (19,400 µg/kg), carbazole

(6,640J µg/kg), chrysene (26,000 µg/kg), dibenz(a,h)anthracene (5,170J µg/kg), dibenzofuran (4,050J

µg/kg), fluoranthene (63,700 µg/kg), fluorene (10,900 µg/kg), indeno(1,2,3-cd)pyrene (11,600 µg/kg),

naphthalene (1,440 µg/kg), phenanthrene (61,400 µg/kg), and pyrene (42,900 µg/kg). The subsurface soil

sample collected from Grid 5, located west of the boiler house, contained cobalt (48.9J mg/kg) and

manganese (1,990J mg/kg) at elevated concentrations. The subsurface soil sample collected from Grid 12

contained chromium (2,200 mg/kg) and copper (175 mg/kg) at elevated concentrations. See Figure 3A in

Appendix A for the grid locations and Table 2 in Appendix B for a complete summary of grid sampling

analytical results.

5.4 UNDERGROUND STRUCTURES SOIL SAMPLING RESULTS

Grab subsurface soil samples collected around the 10,000-gallon diesel UST (designated as DUST in

Table 4 of Appendix B) contained DRO up to 1,370 mg/kg and lead up to 225 mg/kg. Grab subsurface

soil samples collected around the two 500-gallon gasoline USTs (designated as GUST in Table 4 of

Appendix B) contained GRO up to 12.7 mg/kg and lead up to 51.1 mg/kg. Grab subsurface soil samples

collected around the used oil sump (designated as OSP in Table 4 of Appendix B) contained DRO up to



5,460 mg/kg, GRO up to 3,440J+ mg/kg, and lead up to 393 mg/kg. Grab subsurface soil samples

collected around the three oil and water vaults (designated as OVT in Table 4 of Appendix B) contained

DRO up to 14.0 mg/kg and lead up to 14.7 mg/kg. (GRO was not detected.) All of the grab subsurface

soil samples collected around the varsol USTs (designated as VUST in Table 4 of Appendix B) contained

VRO. VRO concentrations ranged from 465J- mg/kg to 14,900J- mg/kg.

Based on the analytical results for samples collected around the underground structures, it appears that the

diesel UST, used oil sump, and the varsol USTs leaked hazardous substances into the surrounding soil.

Comparison criteria for GRO, DRO, and VRO have not been established by EPA or SC DHEC. See

Figure 3B in Appendix A for the underground structures sampling locations and Table 4 in Appendix B

for a complete summary of underground structures sampling analytical results.

5.5 GROUNDWATER SAMPLING RESULTS

Of the six monitoring wells sampled, one well contained VOCs exceeding EPA MCLs. Specifically,

monitoring well MW-13, located near the former machine shop in the office building, contained

tetrachloroethene (PCE) at 55.7 µg/L and trichloroethene (TCE) at 5.4 µg/L, which exceed their EPA

MCL of 5.0 µg/L (Ref. 14). See Figure 3B in Appendix A for the groundwater sampling locations and

Table 5 in Appendix B for a complete summary of analytical results for groundwater.

5.6 SURFACE WATER, SEDIMENT, AND BASEMENT WATER SAMPLING RESULTS

Surface water samples collected from the unnamed tributary of Wildcat Creek contained zinc up to 129

µg/L, which exceeds its freshwater acute (65.04 µg/L) and freshwater chronic (58.91 µg/L) EPA Region

4 SWSVs (Ref. 15). Sediment samples collected from the unnamed tributary of Wildcat Creek contained

PCB-1248 up to 554 µg/kg, which exceeds the EPA Region 4 SSV for total PCBs of 33 µg/kg. Sediment

samples also contained arsenic (9.3J mg/kg), lead (718J mg/kg), and zinc (up to 712J mg/kg) at

concentrations exceeding their EPA Region 4 SSVs (Ref. 16). See Figure 3A in Appendix A for the

surface water and sediment sampling locations and Tables 6 and 7 in Appendix B for a complete

summary of surface water and sediment sampling analytical results.

The water sample collected from the basement of the boiler house contained bis(2-ethylhexyl)phthalate

(4.6J µg/L), arsenic (5.1 µg/L), lead (66.9 µg/L), and zinc (238 µg/L), among others. See Figure 3B in

Appendix A for the location of the basement water sample and Table 6 in Appendix B for a complete

summary of the basement water sampling analytical results.



6.0 SUPPLEMENTAL PHASE II ESA ACTIVITIES, SAMPLING, AND ANALYTICALRESULTS

The following sections summarize supplemental Phase II ESA activities and analytical results. The

discussions address only the hazardous constituents associated with site operations and the hazardous

constituents that may pose a threat to human health or the environment. The sections will focus on results

that exceeded certain EPA guidance values (the same listed in Section 5.0) for the particular medium and

contaminant. See Figures 4 and 5 in Appendix A for additional sampling locations.

6.1 TRENCHING ACTIVITES

In October 2012, in preparation for the Phase II ESA sampling event, all underground structures, objects,

and utilities were mapped using GPR, EM, and conductivity instruments. Several areas where objects

may be buried were identified. Most of these areas corresponded to known underground structures

(USTs, vaults, and sumps) at the RHB site. The City of Rock Hill subsequently requested that EPA

further investigate seven of the areas identified during the geophysical survey to determine whether

previously unidentified buried objects, such as USTs, were present. Therefore, in November 2012, Tetra

Tech returned to the site to oversee trenching activities in the seven areas (AOC-1 through AOC-7)

requested by the City of Rock Hill (see Figure 4 in Appendix A). During trenching, Tetra Tech did not

observe any USTs or other underground structures in the seven areas of concern. However, large pieces

of construction debris, such as sections of brick walls and concrete foundations, were observed in each of

the seven areas (see Appendix D, Photograph No. 15). During excavation in the area of the former

elevator vault (AOC-7), located in the southeastern portion of the site, a strong used oil odor was noted at

about 8 feet bgs. In addition, a strong gasoline odor was noted in the former transformer area (AOC-3) at

around 6 feet bgs. All of the trenches were backfilled prior to demobilization.

6.2 ADDITIONAL SOIL SAMPLING AND ANALYTICAL RESULTS

Based on observations made during trenching, EPA requested that Tetra Tech return to the site to collect

samples in the former elevator vault (AOC-7) and former transformer (AOC-3) areas. In December 2012,

using a DPT drill rig, Tetra Tech collected two grab soil samples (including a duplicate) from the former

elevator vault (designated as EVT in Table 8 of Appendix B) at 8 feet bgs. The samples were analyzed

for DRO, GRO, VOCs, SVOCs, and PCBs. The subsurface soil samples contained DRO up to 2,720

mg/kg, PCB-1254 at 271 µg/kg, anthracene up to 4,740 µg/kg, benzo(a)anthracene up to 12,600 µg/kg,

benzo(a)pyrene up to 6,770 µg/kg, benzo(b)fluoranthene up to 8,220 µg/kg, chrysene up to 12,900 µg/kg,

fluoranthene up to 33,100 µg/kg, indeno(1,2,3-cd)pyrene up to 4,670 µg/kg, phenanthrene up to 21,300



µg/kg, and pyrene up to 23,300 µg/kg. Benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, and

indeno(1,2,3-cd)pyrene were detected at concentrations exceeding their EPA RSLs for industrial soil. See

Figure 5 in Appendix A for additional soil sampling locations and Table 8 in Appendix B for a complete

summary of analytical results.

Four soil borings were advanced north, east, south, and west of the trench that contained the gasoline odor

in the former transformer area (AOC-3) (designated as FTA in Table 8 of Appendix B). Free product was

observed in the northern and southern soil borings at 4.5 to 5.5 feet bgs and 5.5 to 6.5 feet bgs. A strong

gasoline odor was also noted. The eastern and western soil borings did not have an odor and did not

contain free product; therefore, samples were not collected from these borings. Grab subsurface soil

samples were collected from the northern (RHB-FTA-SB-01-(5.5′)) and southern (RHB-FTA-SB-02-

(6.5′)) soil borings at the depths containing free product. The samples were analyzed for GRO, VOCs,

PCBs, and metals. The samples contained GRO up to 1,690 µg/kg, ethylbenzene at 315J µg/kg,

isopropylbenzene up to 18,400 µg/kg, methylcyclohexane at 2,190J µg/kg, and arsenic up to 1.8 mg/kg.

PCBs were not detected in either sample. See Figure 5 in Appendix A for additional soil sampling

locations and Table 8 in Appendix B for a complete summary of analytical results.

6.3 FORMER TRANSFORMER AREA FREE PRODUCT DELINEATION AND SOILSAMPLING RESULTS

Because gasoline free product was present in the former transformer area during the December 2012

additional soil sampling event, Tetra Tech was tasked by EPA to delineate the lateral and vertical extent

of the gasoline contamination. On January 10, 2013, soil borings were advanced radially from the trench

at 20-foot intervals (see Figure 5 in Appendix A). Soil borings were advanced down to 15 feet bgs and

were screened continuously for VOCs using a PID. (See Table 9 in Appendix B for PID readings and

Appendix C for the former transformer area field sheets.) Tetra Tech continued to advance borings

radially until VOCs were not detected with the PID. Based on PID readings, gasoline free product

extends laterally about 20 feet north of the trench and about 80 feet south of the trench. Vertically, the

free product is shallowest (between 0 and 5 feet bgs) in soil boring 7A and deepest (down to 15 feet bgs)

in soil borings 3A and 3D. (See Figure 5 in Appendix A and Table 9 in Appendix B.)

Tetra Tech collected six grab subsurface soil samples with a mixture of high, mid-level, and low PID

readings to confirm the PID screening. The soil samples were analyzed for GRO and selected VOCs,

including benzene, ethylbenzene, isopropylbenzene, methylcyclohexane, methyl tert-butyl ether (MTBE),

naphthalene, toluene, and xylenes. The VOCs were selected based on the results of the soil samples

collected in December 2012 in the former transformer area. In addition, three samples were analyzed for



PCBs because this area was once the location of a power substation and transformers. The samples

contained GRO up to 1,400 mg/kg, ethylbenzene up to 1,590J µg/kg, isopropylbenzene up to 26,200

µg/kg, methylcyclohexane up to 4,210J µg/kg, and naphthalene up to 18,100 µg/kg. Naphthalene

exceeded its EPA RSL of 18,000 µg/kg for industrial soil in sample RHB-FTA-SB-03-(11′). PCBs were

not detected in soil samples collected from the former transformer area. See Table 8 in Appendix B for a

complete summary of analytical results.

7.0 SUMMARY OF FINDINGS

A Phase II ESA was conducted at the RHB site between October 2012 and January 2013 to assess various

RECs, potential RECs, and other environmental hazards. The assessment included sampling of surface

and subsurface soil, groundwater, surface water, and sediment. The results of the Phase II ESA

investigation suggest RECs currently exist at the RHB site that warrant consideration in planning future

uses of the property. The following issues should be considered:

Surface soil samples (0 to 1 foot bgs) collected in the former chrome plating area containedSVOCs and metals at concentrations exceeding EPA RSLs for industrial soil. Subsurface soilsamples (2 to 4 feet bgs) contained arsenic at concentrations exceeding its EPA RSL for industrialsoil. In addition, butylbenzylphthalate was detected in one surface soil sample at an elevatedconcentration. Subsurface soil samples contained arsenic, chromium, lead, mercury, and zinc,among others, at elevated concentrations.

Subsurface soil samples (1.5 to 2 feet bgs) collected from the proposed grassy area, located northof the office building, contained benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene,dibenz(a,h)anthracene, and indeno(1,2,3-cd)pyrene at concentrations that exceeded their EPARSLs for industrial soil. In addition, surface and subsurface soil samples contained elevatedconcentrations of SVOCs.

Composite subsurface soil samples (1 to 1.5 feet bgs) were collected from 18 grids across theproperty. Of those, 11 grids contained SVOCs at concentrations exceeding their EPA RSLs forindustrial soil and nine grids contained arsenic at concentrations exceeding its EPA RSL forindustrial soil. Several grids also contained elevated concentrations of SVOCs and metals.

Soil samples collected around the 10,000-gallon diesel UST (between 2 and 6 feet bgs) containedDRO up to 1,370 mg/kg and lead up to 225 mg/kg. Soil samples collected around the two 500-gallon gasoline USTs (between 2 and 11 feet bgs) contained GRO up to 12.7 mg/kg and lead upto 51.1 mg/kg. Soil samples collected around the used oil sump contained DRO up to 5,460mg/kg, GRO up to 3,440J+ mg/kg, and lead up to 393 mg/kg. Soil samples collected around thethree oil and water vaults contained DRO up to 14.0 mg/kg and lead up to 14.7 mg/kg. (GROwas not detected.) All of the soil samples collected around the varsol USTs (between 4 and 20feet bgs) contained VRO ranging from 465J- mg/kg to 14,900J- mg/kg. Based on these results, itappears that the diesel UST, used oil sump, and the varsol USTs leaked hazardous substances intothe surrounding soil.



Of the six monitoring wells sampled, only one well contained VOCs exceeding EPA MCLs. Thesample from monitoring well MW-13, located near the former machine shop in the officebuilding, contained PCE at 55.7 µg/L and TCE at 5.4 µg/L, which exceed their EPA MCL of 5.0µg/L.

Surface water samples collected from the unnamed tributary of Wildcat Creek contained zinc upto 129 µg/L, which exceeds its freshwater acute (65.04 µg/L) and freshwater chronic(58.91 µg/L) EPA SWSVs. Sediment samples collected from the unnamed tributary of WildcatCreek contained PCB-1248 up to 554 µg/kg, which exceeds the EPA SSV for total PCBs of33 µg/kg. Sediment samples also contained arsenic (9.3J mg/kg), lead (718J mg/kg), and zinc (upto 712J mg/kg) at concentrations exceeding their EPA SSVs.

The water sample collected from the basement of the boiler house contained bis(2-ethylhexyl)phthalate (4.6J µg/L), arsenic (5.1 µg/L), lead (66.9 µg/L), and zinc (238 µg/L),among others. No oil-related hazardous substances were detected.

In November 2012, in response to concern from the City of Rock Hill, Tetra Tech conductedtrenching in seven areas that were identified during the geophysical survey as possibly containingburied objects. Tetra Tech did not observe any USTs or other underground structures in the areasof concern; however, Tetra Tech did observe large pieces of construction debris, such as sectionsof brick walls and concrete foundations. During excavation in the area of the former elevatorvault, a strong used oil odor was noted at about 8 feet bgs. Furthermore, one of the trenches inthe former transformer area contained a strong gasoline odor at about 6 feet bgs.

In December 2012, based on observations made during the trenching, Tetra Tech collectedsamples (up to 8 feet bgs) in the former elevator vault and former transformer areas. The elevatorvault samples contained DRO up to 2,720 mg/kg, PCB-1254 at 271 µg/kg, anthracene up to 4,740µg/kg, benzo(a)anthracene up to 12,600 µg/kg, benzo(a)pyrene up to 6,770 µg/kg,benzo(b)fluoranthene up to 8,220 µg/kg, chrysene up to 12,900 µg/kg, fluoranthene up to 33,100µg/kg, indeno(1,2,3-cd)pyrene up to 4,670 µg/kg, phenanthrene up to 21,300 µg/kg, and pyreneup to 23,300 µg/kg. Soil samples collected from the former transformer area contained GRO upto 1,690 µg/kg, ethylbenzene at 315J µg/kg, isopropylbenzene up to 18,500 µg/kg, andmethylcyclohexane at 2,190J µg/kg. PCBs were not detected.

In January 2013, because gasoline free product was present in the former transformer area, TetraTech advanced soil borings radially from the trench at 20-foot intervals to delineate the lateraland vertical extent of the gasoline. Based on the PID screening, a line of gasoline free productextends laterally to 20 feet north of the trench to about 80 feet south of the trench. Vertically, thefree product is down to 15 feet bgs. Soil samples collected from the former transformer areacontained GRO up to 1,690 mg/kg, ethylbenzene up to 1,590J µg/kg, isopropylbenzene up to26,200 µg/kg, methylcyclohexane up to 4,210J µg/kg, and naphthalene up to 18,100 µg/kg.Naphthalene and arsenic were detected in soil samples at concentrations exceeding their EPARSLs for industrial soil. PCBs were not detected in any soil samples collected from the formertransformer area.
