1.0 INTRODUCTION

On behalf of Deere-Hitachi Construction Machinery Corporation (Deere-Hitachi), ERM
NC, Inc. (ERM) has prepared a Soil Management Plan for the former Varcon-Pruden
Buildings (VPB) site located at 1140 West Mountain Street in Kernersville, North
Carolina (the subject property). The purpose of the plan is to establish procedures for
managing future soil disturbances on the property. The need for such a plan was
specified in Section V of the draft Brownfields Agreement between the North Carolina
Department of Environment and Natural Resources (NCDENR) and Deere-Hitachi,
Brownfields Project No. 16061-12-34.

1.1 SITE DESCRIPTION AND BACKGROUND

The subject property includes 27.05 acres of land developed for industrial use.
Approximately 8,690 square feet of the southeast corner is separated from the
remainder of the subject property by Perry Road. The subject property is developed
with a 167,000-square-foot structure and two smaller auxiliary storage buildings; each
structure was reportedly constructed in 1966.

Exterior features of the subject property include paved parking areas, unsheltered
gravel product storage areas, wooded areas, and access roads. Sediment/storm water
retention ponds are located along the north and northwest property boundaries.
Access to the subject property is provided from the south via West Mountain Street
and from the east via Perry Road. Surrounding properties are residences, wooded
land, and industrial properties, including Deere-Hitachi manufacturing.

The subject property was developed by Varco-Pruden Buildings (VPB) in 1966 for the
manufacture of pre-engineered metal buildings. The manufacturing building was
constructed in phases from 1966 to 1989. The onsite warehouse was built in 1977 as a
maintenance facility and the smaller auxiliary structure was built in 1990 for storage.
VPB occupied the subject property until approximately 2010; however, the
manufacturing of pre-engineered metal buildings ceased in 2007. Central Glass &
Mirror Company occupied the warehouse from 2007 to 2010. The subject property was
then sold in 2010 by BlueScope Buildings North America, Inc. (which purchased VPB
in 2008) to Atlantic Precast Company, LLC (APC), and occupied by Carolina Cast
Stone Company, a division of APC. Carolina Cast Stone remained onsite until June
2012 when they vacated the subject property. The subject property is currently
unoccupied.

1.2 ENVIRONMENTAL SITE ASSESSMENTS

The following environmental site assessments have been conducted at the subject
property since 1995:

 Subsurface Investigation, NET Project #323001, prepared by National Environmental
Technologies (NET), dated October 1995;
 Administrative Order on Consent (AOC), Varco-Pruden Buildings Site, prepared by
United Dominions Industries, Inc. (UDI), dated September 22, 1997;
 Phase I Remedial Investigation Report/Phase II Investigation Workplan, prepared by
Delta Environmental Consultants, Inc. (Delta), dated March 1998;
 Phase II Remedial Investigation Report, prepared by Delta, dated November 2000;
 Soil Remedial Action Completion Report, prepared by Delta, dated February 2005;
 Limited Soil Assessment Report, prepared by Delta, dated December 2007;
 Phase I Environmental Site Assessment (ESA), prepared by Coastal Environmental
Consulting, Inc. (CEC), dated July 2010;
 Remedial Progress Report – June 2011, prepared by Antea USA, dated August 26,
2011; and
 Phase I ESA, prepared by URS Corporation (URS), dated September 2012.

A summary of the two known release areas at the site is presented below.

Former Drum/Debris Burial Area

Buried drums and industrial refuse were discovered at the northwest corner of the
subject property during installation of a storm water drainage system in 1995.
National Environmental Technologies (NET) conducted a subsurface investigation to
determine the extent of the hazardous waste burial area. Seven test pits were
excavated in the area of the drums/refuse. Various debris was found, including
crushed drums, metal and wood scrap, electrical wiring, piping, spent welding rods,
and paint materials. It was determined that the waste disposal area was
approximately 6,500 square feet, and extended to a maximum depth of eight feet;
however, the extent of the buried waste was not fully delineated due to the inaccessible
wooded area to the north. Soil samples collected in these areas revealed the presence
of toluene, ethyl benzene, xylenes, 2-butanone, tetrachloroethylene (PCE), and bis(2-
ethylhexyl)phthalate (BEHP). Several metals were identified in both soil and ground
water samples, but at concentrations below their respective regulatory remedial
objectives (ROs). As the constituents of concern (COCs) were determined to be
relatively mobile in the subsurface environment, NET recommended that additional
subsurface investigations be conducted, specifically for PCE.

In May 1996, NET advanced four onsite monitoring wells (MW-1 to MW-4).
Groundwater sampling and analyses indicated the presence of PCE in the shallow
ERM NC, Inc. 3 Soil Management Plan - Varco Pruden Site.docx
groundwater at the site. Unfiltered samples collected from the wells indicated the
presence of several RCRA metals above regulatory remedial objectives (ROs); however,
filtered samples did not reveal such elevated concentrations. NET presumed that PCE-
affected ground water may extend offsite; therefore, it was recommended that ground
water monitoring continue.

Delta (now known as Antea USA) conducted ground water sampling at the subject
property in June 1997; samples exhibited concentrations of BEHP above regulatory
ROs. Delta also collected soils samples to determine background levels of total and
leachable concentrations of Priority Pollutant Metals.

Excavation of onsite buried debris was conducted from June 30 to August 7, 1997.
Wastes encountered included metal debris, wire, wood, sheet metal, crushed and
empty drums, and drums containing unidentified waste, liquids, and general trash.
Liquids encountered were removed via vacuum truck. Drums containing solids, and
impacted soils were stockpiled as suspected hazardous/ non-hazardous wastes.
Confirmation sampling indicated that the 6,800 tons of waste generated did not qualify
as hazardous. Ten drums of unidentified waste were sampled for waste
characterization purposes and sample results indicated that this material exhibited
hazardous waste toxicity/ignitability characteristics. The hazardous wastes were
disposed offsite in December 1997. Confirmation soil sampling was conducted within
the vicinity of the excavation area and samples collected exhibited COCs (including
PCE) at levels below regulatory ROs, with the exception of BEHP. Concentrations of
BEHP were exhibited at levels above “protection of ground water” soil ROs.
Additional excavation was not conducted in the area of the BEHP concentration as the
depth of this exceedence was reportedly below the reach of the excavation equipment.
The excavation area was subsequently backfilled. (Re-sampling of this area in
subsequent investigations did not reveal elevated concentrations of BEHP in onsite soil
or ground water).

The 2000 Phase II Remedial Investigation Report prepared by Delta summarized the
advancement of soil borings, 15 temporary monitor wells, and six additional
permanent monitor wells (MW-5 to MW-10) between June 1998 and March 2000. Soil
and ground water samples were analyzed for volatile organic compounds (VOCs),
semi-VOCs (SVOCs), metals, and natural attenuation parameters. No additional soil
contamination was discovered during the assessment. Ground water in the northwest
portion of the site was found to be impacted by several chlorinated solvent
compounds, including trichloroethylene (TCE), PCE, and cis-1,2-dichloroethylene
(DCE), which were present in concentrations above their respective ground water ROs.

A June 2011 Remedial Progress Report prepared by Antea USA (formerly known as
Delta) indicated that ground water samples collected from onsite monitoring wells
continued to have TCE, PCE, and cis-1,2-DCE at concentrations above their respective
ground water ROs. The report further indicated that analytical data collected from the
site were not “indicative of reductive dechlorination inside the contaminant plume”.
PCE was also identified in surface water samples (SW00100, SW00200 and SW00300)
collected in concentrations exceeding the respective RO. The surface water samples
ERM NC, Inc. 4 Soil Management Plan - Varco Pruden Site.docx
were collected from a tributary located approximately 200 feet offsite to the northwest.

The release of chlorinated VOCs in the vicinity of the former drum/debris disposal
area is currently managed under the Registered Environmental Consultant (REC)
program which is administered by the NCDENR Inactive Hazardous Sites Branch
(IHSB). A Remedial Action Plan (RAP) was prepared on behalf of SPX Corporation,
former parent company of Varco Pruden Buildings, in November 2002 by Antea
(Delta). SPX Corporation is responsible for implementation of the RAP. Long term
monitoring of ground water and surface water quality is currently being conducted
annually by Antea on behalf of SPX in accordance with the approved RAP.

Former Gasoline & Diesel USTs

The 2007 Limited Soil Assessment Report, prepared by Delta, summarized the assessment
of a former 1,000-gallon gasoline underground storage tank (UST) located on the east
side of the building (adjacent to a former truck scale) and a 10,000-gallon diesel UST
located near the eastern property boundary. These USTs were removed from the site
in 1990. According to the report, soil samples collected beneath the 10,000-gallon
diesel UST did not indicate the presence of petroleum hydrocarbons. Soil samples
collected from beneath the 1,000-gallon gasoline UST contained gasoline-range total
petroleum hydrocarbons (TPH) at 48 parts per million (ppm) which exceeded the
NCDENR general action limit of 10 ppm. The tank closure contractor, Southern Pump
and Tank Company (SPATCO), proceeded to excavate approximately 156 tons of
petroleum-affected soil from the tank basin. One of the confirmatory soil samples
detected gasoline range TPH at 117 ppm. One ground water monitoring well was
installed on the north side of the former gasoline UST basin in August 1990. Toluene
was detected in the ground water sample from this well at 5 parts per billion (ppb) and
xylenes was detected at 10 ppb. These concentrations were well below the applicable
North Carolina Ground Water Standards (15A NCAC .0200 2L, or NC 2L Standards).
The well was resampled several times over the next two years, with the last event in
2002 not detecting VOCs. In 2007, the NCDENR directed VPB to conduct an additional
soil assessment at the former gasoline UST location. Soil samples collected from a
boring installed within the former tank basin between 20 and 30 feet below grade. No
VOCs were detected in the soil samples. Based on these data and previous ground
water sample results, the NCDENR issued a Notice of No Further Action on December
19, 2007 with regard to the gasoline UST.

1.3 SITE ACTIVITY LIMITATIONS

There are no activity limitations that currently apply to the site. Land use restrictions
(LURs) are proposed under the draft Brownfields Agreement including limiting the
site to heavy industrial, light industrial or office uses; restrictions on ground water or
surface water use; implementation of a NCDENR-approved soil management plan;
and, mitigation measures for any new buildings constructed for protection potential
future vapor intrusion concerns. Other LURs are included in the draft Brownfields
Agreement. These site activity limitations will become effective upon execution of the
ERM NC, Inc. 5 Soil Management Plan - Varco Pruden Site.docx
Brownfields Agreement. No LURs associated with the former petroleum USTs and
gasoline release have been required by NCDENR.

1.4 SITE REDEVELOPMENT PLANS BY DEERE-HITACHI

Deere-Hitachi, as prospective developer of the site, plans to utilize the existing facilities
to expand their excavator manufacturing capabilities in Kernersville. Additional
infrastructure will be incorporated into the site to support Deere-Hitachi’s
redevelopment operations. This may include heavy infrastructure requiring footings
such as hoists and presses as well as pits or underground utilities. Soil excavations
may be necessary for installation of this equipment.

2.0 SITE RISK EVALUATIONS

This section provides an overview of the potential human exposure risk posed by the
site, establishes a conceptual site model, and provides approaches for reducing
potential soil exposure risk both during site redevelopment and after the site
redevelopment is completed.

2.1 EXPOSURES

As discussed in Section 1.2, soils at the subject property have historically been affected
with VOCs and SVOCs. Soil excavation activities have removed soils with known
impact; however, based on the historical industrial use of the property, the potential
exists that similar impacts are still present onsite. The potential for human exposure to
site soils is very low under normal (non-invasive) circumstances. Table 1 presents soil
contaminant concentrations in the vicinity of the debris/drum disposal area following
excavation and off-site disposal of impacted materials. All known soil contaminant
concentrations are below the current Preliminary Industrial Health- Based Soil
Remediation Goals (PSRG) established by the NCDENR IHSB. Preventing exposure to
potentially more significantly affected soil will be controlled using the procedures
outlined in the following sections of this plan.

Exposure to site ground water is not expected as there is no current or anticipated
future use of groundwater at the site as the property is served by public water supply,
and groundwater is present at depths greater than 18 feet below ground surface.
Additionally, impacted surface water (identified during previous environmental
assessments) is present off-site and is not expected to be encountered during site
redevelopment activities. Table 2A presents the most recent VOCs concentrations in
ground water exceeding the applicable NC 2L standards at the site and Table 2B
presents the most recent VOCs concentrations in surface water samples exceeding the
applicable NC 2B surface water standards. All surface water samples have been
ERM NC, Inc. 6 Soil Management Plan - Varco Pruden Site.docx
collected off-site downgradient of the former drum/debris disposal area. Exposure to
site ground water and offsite surface water is not addressed in this plan.

3.0 SOIL MANAGEMENT PLAN

This plan addresses actions to be taken in the event that any planned, or unplanned,
disturbances of soil occur at the facility which could potentially result in the exposure
of employees or site workers to COCs historically present onsite (discussed in Section
2.1) or other unknown chemicals. This plan also highlights activities to be performed
to minimize impact to human health and the environment throughout site
redevelopment. This section outlines the soil management requirements for the site.

3.2 SOIL DISTURBANCE GUIDELINES

The guidelines presented in this section have been prepared to allow for the proper
future handling of soil excavated at the site during both the construction and the
developed site phases. The site owner/developer/contractor is required to conduct
excavation activities in accordance with the NCDENR-approved soil management
plan. The purpose of this requirement is to assure that site soil is managed in a safe
and environmentally sound manner.

It should be noted that this Soil Management Plan focuses on known areas of historical
contamination however; the following procedures are applicable for all soil
disturbances and can be utilized for future redevelopment activities at the site.
ERM NC, Inc. 7 Soil Management Plan - Varco Pruden Site.docx
General Requirements

Notice shall be submitted to the NCDENR Brownfields Section at least five days prior
to excavation activities. The notification must indicate the location of the work, the
estimated volume of soil to be disturbed, the persons or firms conducting the work, the
schedule for the work, and assurances that the excavation work will be conducted in
accordance with the NCDENR-approved soil management plan.

Management of excavated soil should follow the health and safety guidelines
established in the site-specific health and safety plan (HASP) and applicable
Occupational Safety and Health Administration (OSHA) requirements.

3.2.1 Limited Impact Soil Areas

Historical post-excavation confirmation soil sampling results indicate that all soil has
been remediated to below applicable remedial objectives. This includes the previous
drum, debris and soil removal area at the north side of the building plus the former
gasoline UST and diesel UST areas. No significantly impacted soil is expected to be
encountered during site redevelopment of these areas.

All soil excavated as part of site redevelopment should remain on-site unless gross
contamination is encountered during excavations. Any excavated soil shall be placed
within the boundary of the subject property and protected from erosion as necessary.
No additional sampling, characterization or remediation of soil to remain onsite is
required unless gross contamination is suspected. See Section 3.2.2 below for
procedures regarding soil suspected to be grossly contaminated based on field
observations during excavation.

Any soil from the areas of potential concern identified on Figure 2 that requires off-site
disposal must be temporarily stockpiled onsite, sampled and disposed off-site in
accordance with applicable regulatory requirements. NCDENR must be notified prior
to off-site disposal of any soils. The notification must include the estimated volume of
soil, analytical results, final destination of the soil and a list of any contractors
involved.

3.2.2 Grossly Impacted Soils

No areas of soil contamination considered to be grossly impacted are known or
suspected on the site. The following guidelines are provided in the event soil
suspected to be significantly contaminated is encountered during excavation activities
based on field observations.

In the event that discolored or odorous soils suspected to be significantly contaminated
or other evidence of potential contamination such as buried drums or debris are
encountered during excavation activities, work must stop and the excavation (and
spoils pile) will be covered with an impermeable liner, such as 6-mil plastic sheeting.
ERM NC, Inc. 8 Soil Management Plan - Varco Pruden Site.docx
Deere-Hitachi and ERM will be contacted concerning the next steps. Additional steps
for managing impacted soils may include the following:

 All further work in the area of suspected soil contamination shall be performed
consistent with applicable OSHA requirements for protection of workers
(including hazard communication, a HASP, and HAZWOPER 40-hour trained
persons). Appropriate engineering controls will be employed to mitigate
human contact through the release of airborne vapors and/or particulates,
physical contact that allows for ingestion, and storm water runoff beyond the
work area.

 Excavated soils will either be: 1) stockpiled on an impermeable surface (e.g. 6-
mil plastic sheeting) and kept covered; or 2) placed inside a closed container,
such as a DOT-approved 55-gallon drum or roll-off container.

 All excavated soils in storage will be labeled as, “potentially contaminated soil”
or with similar language until properly characterized for disposal.

 Documentation of the date the soils were generated will be recorded and
maintained onsite, either labeled on the soil container or stockpile, or
maintained in the facility files (electronic or paper copy). Excavated soils will
not be stored onsite for periods longer than 60 days following the cessation of
field activities.

 General sampling guidelines for stockpiled soils are provided in Section 3.3.
Sampling is to be performed by qualified and experienced personnel.

 Based upon analytical results and with NCDENR approval, excavated soil may
be allowed to be reused in another area of the site or as backfill in the original
excavation. Soil exhibiting contaminant concentrations exceeding the applicable
NCDENR IHSB Preliminary Industrial Health-Based Soil Remediation Goals
(PSRG) require off-site disposal.

 If off-site disposal of any quantity of soil is required, the owner will contract
with properly licensed contractor(s) and disposal facilities for proper transport
and disposal of soil. The owner will provide the soil disposal information,
including waste characterization/ profile acceptance data, manifests or bills of
lading, and other pertinent data in a submittal to the NCDENR. Other analyses
may be required by the disposal facility prior to accepting the soil.

 The owner, or party responsible for moving the soil, will prepare and submit a
report to the NCDENR that summarizes the soil management activity, including
final weight of the soil or debris, ultimate disposition of the soil or debris, and
dates that the work was performed.

ERM NC, Inc. 9 Soil Management Plan - Varco Pruden Site.docx
3.3 POST-EXCAVATION SOIL SAMPLING REQUIREMENTS

Any soil excavated from the areas of potential concern identified on Figure 2 that
require off-site disposal or soil suspected to be grossly contaminated requires that the
soil be sampled to determine the presence and nature of potential contamination prior
to disposal. A brief Sampling Plan outlining the number and locations of samples from
the stockpiled soil will be developed based on the NCDENR IHSB Guidelines for
Assessment and Cleanup (current version – April 2013) and provided to the NCDENR
for approval prior to initiating disposal. The Sampling Plan will include the list of
analytical parameters and methods to be used, and reference existing data to refine the
selected analyses by identifying likely constituents. Guidelines from the current
version of NCDENR IHSB’s guidelines are summarized below.

Soils/wastes must meet IHSB remediation goals before they can be replaced on
site. Soil stockpiles should be sampled using the following procedures.

1. Stockpiles should be divided into equal segments of approximately 100
cubic yards each. Within each segment, use either random or biased
selection to locate at least three hand-auger borings.
2. Samples should be collected from two depths within each boring
(minimum six samples per segment).
3. Use visible or field-screening evidence to collect additional biased
samples from areas of residual contamination.
4. Samples may be composited only within each segment. For samples
submitted for volatiles analysis, at least 25% should be collected as
unmixed grab samples.
Soil exhibiting contaminant concentrations exceeding the applicable NCDENR IHSB
Preliminary Industrial Health-Based Soil Remediation Goals (PSRG) require off-site
disposal. All other soils may be reused onsite as backfill from the existing excavation
or spread onsite. The results of the soil sample analyses are required to be reported to
the NCDENR to allow removal, reuse, and/or disposal.
