Subject: Brownfields Site Assessment Work Plan
Former BASF Corporation Facility
Enka, North Carolina
Dear Ms. Wahl:
On behalf of Enka Partners of Asheville, LLC (Enka Partners), Altamont Environmental, Inc.
(Altamont) has prepared this Brownfields Site Assessment work plan based on discussions with the
North Carolina Department of Environment and Natural Resources (DENR), Division of Waste
Management (DWM) personnel.
Background
The subject property is a portion of the former BASF facility located off of Sand Hill Road in the Enka
community of Buncombe County, North Carolina. The subject property was purchased from BASF
by Enka Partners of Asheville, LLC (Enka Partners). Enka Partners (the landowner and prospective
developer) is managing the portions of the property that will be investigated during the Brownfields
Site Assess ment. Enka Partners is in the process of redeveloping the property under a Brownfields
agreement with the DENR and plans to use the property for retail space. A site location map is
attached as Figure 1.
A Brownfield Area Reconnaissance and Receptor Survey were conducted for this property by
Altamont in October 2008. According to the survey, two private water supply wells were located
within one-half mile of the subject property.
Site Assessment
It has been determined that there are three main areas of concern on the property that DENR
would like Enka Partners to have investigated as part of the Brownfields Site Assessment:
• The caustic tanks recently discovered on-site
• Soi l brought on-site from a Mission Hospital construction area
• Former spray pond area
Caustic Tanks
Enka Partners is taking responsibility for the assessment of the caustic tank area (Figure 2).
Altamont developed a work plan to confirm that contamination does not exist following tank
removal and cleanup. The confirmation sampling work plan was submitted to the DENR Division of
Waste Management Hazardous Waste Section on November 2, 2010, for the assessment of the soils

in this area. Excess soil and decontamination liquid that results from drilling during this task will be
containerized in a 55-gallon drum{s). Based upon the analytical results of the soil sample taken
from the boring, the containerized material will either be: 1. Spread on-site (if the soils do not
contain contaminants in levels greater than the DENR Inactive Hazardous Sites Branch's {IHSB's)
standards), 2. Transported to a subtitle D landfill (if soils are greater than the IHSB limits, but non-
hazardous), or 3. Transported to a certified hazardous disposal facility/landfill (if soils exceed IHSB
limits and are classified as hazardous). The wo-rk plan was approved by DENR on November 9,
2010, and sampling is scheduled to begin during January 2011. Please refer to the attached work
plan and approval letter in Appendix A for more information.
Soils from Off-Site Location
Based on the November 4, 2010, meeting between Altamont, Enka Partners, and the DENR, it was
determined that soils have been brought on-site from an off-site source. Altamont reviewed the
following reports to aid in the preparation of this soil assessment:
• Bunnell-Lammons Engineering, Inc. (BLE), October 22, 2007, Report of Preliminary
Geotechnical Exploration for the Mission Hospitals Victoria Road Realignment Project
• BLE, December 14, 2009, Report of Geotechnical Exploration for the Orthopedic Appliance
Company Proposed Medical Office Building
After reviewing the geotechnical documents described above and based on correspondence with
Jay Maveety of Mission Hospitals, soils that were placed on the former BASF site originated most
likely from the construction area west of Victoria Road and east of McDowell Street in downtown
Asheville, North Carolina. The reports mentioned above did not identify any potential sources of
contamination for the soils. However, the DENR has requested that samples be collected from
these soils to confirm they are not contaminated. The approximate off-site soil area consists of
1.35 acres and is indicated on the attached Figure 2.
Soil Samples
Altamont will mobilize to the site and install hand auger borings in four soil sample locations. The
borings will be located throughout the area where the soils from the Mission Hospital construction
site were placed. The exact sample locations and depths will be determined in the field.
Disposable gloves will be utilized and changed between sampling locations to avoid cross-
contamination. The hand auger will be decontaminated between sampling locations using a
Liquinox® wash and distilled water rinse. Excess soil from the hand augering will be placed back in
the boring hole from which it came. One duplicate sample and an equipment rinsate blank will be
collected. All samples will be placed in the appropriate sample containers in a cooler on ice to
await delivery to the laboratory.
Laboratory Analysis
Altamont will utilize a laboratory appropriately certified by the State of North Carolina to analyze
the soil samples. The proposed samples will be analyzed for Hazardous Substance List (HSL)
metals using SW-846 Methods 6010 and 7471 (for mercury) and Total Petroleum Hydrocarbons
(TPH)-Gasoline Range Organics (GRO) and Diesel Range Organics (DRO) using EPA Method 8015.
HSL metals include antimony, arsenic, beryllium, cadmium, chromium, copper, lead, manganese,
mercury, nickel, selenium, silver, thallium, and zinc.
Former Spray Pond
A pond used to exist in the northern portion of the site that was utilized in the past by BASF as a
wastewater spray pond (Figure 2). DENR has requested that this former pond area be assessed
during the project by collecting and analyzing soil and groundwater samples.

Soil Samples
Altamont will mobilize to the site and direct the drilling contractor, who will be present for the
caustic tank area assessment, to advance soil borings in four sample locations. The borings will be
located within the footprint of the former spray pond. The exact sample locations and depths will
be determined in the field. One of the soil samples will be collected during the monitoring well
installation mentioned below. All equipment, well materials, and tools that will enter the borehole
must be steam-cleaned with a high-temperature pressure washer prior to installation. The cleaned
materials will be protected from possible contaminants (e.g. wrapped in clean plastic). Water used
in the decontamination processes, as well as during the drilling should be obtained from a source of
known quality that does not contain constituents of concern.
Disposable gloves will be utilized and changed between sampling locations to avoid cross-
contamination. A decontaminated stainless steel spoon and bowl will be utilized to collect each soil
sample and will be decontaminated using a Liquinox® wash and distilled water rinse between
sampling locations. All samples will be placed in the appropriate sample containers in a cooler on
ice to await delivery to the laboratory.
Excess soil and decontamination liquid that results from drilling will be containerized in a 55-gallon
drum(s). Based upon the analytical results of the soil sample taken from the boring, the
containerized material will either be: 1. Spread on-site (if the soils do not contain contaminants in
levels greater than the DENR Inactive Hazardous Sites Branch's (IHSB's) standards), 2. Transported
to a subtitle D landfill (if soils are greater than the IHSB limits, but non-hazardous), or 3.
Transported to a certified hazardous disposal facility/landfill (if soils exceed IHSB limits and are
classified as hazardous).
Monitoring Well Installation and Groundwater Samples
Monitoring Well Installation
A monitoring well will be installed within the footprint of the former spray pond to facilitate the
collection of groundwater samples. Altamont will direct the North Carolina licensed drilling
contractor to install the monitoring well screened across the water table. The monitoring well
boring will be advanced using 4.25-inch hollow-stem augers (HSAs) powered by a conventional drill
rig. The standard methods for the design and installation of the monitoring well will be followed,
which includes installing a sand pack and grouting the monitoring well in place. Boring logs and
monitoring well construction logs will be prepared and included in the final summary report.
All equipment, well materials, and tools that will enter the borehole must be steam-cleaned with a
high temperature pressure washer prior to installation. The cleaned materials will be protected
from possible contaminants (e.g. wrapped in clean plastic). Water used in the decontamination
processes, as well as during the drilling and well installation procedures, as described below, should
be obtained from a source of known quality that does not contain constituents that could
compromise the integrity of the monitoring well.
Altamont will collect soil screening samples every five feet within the monitoring well boring. Each
sample will be mixed and then split. Each split soil sample will be placed into a new low-density
polyethylene bag (i.e. Ziploc® bag), which will then be sealed. One bag of the split sample will be
allowed to volatilize in a warm environment for at least ten minutes, while the other split sample
will be placed on ice in a cooler. Using a Mini-RAE 2000® organic vapor analyzer (OVA) with photo
ionization detection (PIO), the headspace in each bag that was allowed to warm and volatilize will
be screened for indications of volatilized organic compounds (VOCs). Altamont will collect a sample
from the split soil sample (using the corresponding sample in the cooler) with the highest reading
on the OVA. If the soil screening does not indicate the presence of voes, Altamont will collect a soil
sample from the perceived bottom of the former spray pond. The approximate depth of the bottom
will be determined based upon soil lithology observed during the installation of the soil borings.

The monitoring well will be composed of two-inch nominal inside-diameter (ID) Schedule 40 PVC.
The screen shall be 10 feet in length and will be machine-slotted with 0.010-inch slots. The filter
pack material will be a clean, washed, well-rounded silica sand sized to perform as a filter between
the formation material and the well screen.
The bentonite seal shall be composed of commercially manufactured sodium bentonite pellets,
which do not exceed 0.25-inch in diameter. If the bentonite is installed above the water table, as is
anticipated during this task, then clean, potable water will be used to hydrate the bentonite.
The cement grout will consist of a neat mixture of Portland cement and water in the proportion of
approximately six to seven gallons of approved water per 94-pound bag of cement. Water may be
added to the mix in small amounts, at the discretion of Altamont, to achieve pumpability.
The casing/screen assembly for the monitoring well will be installed as follows:
• Prior to installation of the casing and screen, the lengths and diameters of all components
(including the bottom plug or cap) will be measured (to the nearest hundredth foot) and
recorded in the field book. The casing riser and screen assembly will be installed round,
plumb, and true-to-line.
• The well screen will be connected to the riser sections of the casing assembly. The well
screen will be installed so as to straddle the free water surface, extending both above and
below the water table to accommodate seasonal or other variations in its elevation. In all
cases, the top of the screen will be located at least two feet below the base of the down hole
bentonite seal.
• The filter pack will be placed in the annulus between the well material and borehole by
pouring the material directly through the annular space between the well and the
borehole/HSAs. A clean PVC pipe or weighted tape will be used as a tamping device to
prevent bridging of the filter pack and to continuously tag its depth. The HSAs will be raised
incrementally during the installation of the filter pack. Care will be taken to keep the bottom
of the HSAs below the top of the filter pack during installation. The level of the top of the
filter pack in the annulus will be verified by tag-line measurement during all phases of
placement. The filter pack will extend at least two feet above the top of the screen. The
volume of the installed filter pack will be compared with the annular volume to verify proper
placement of the filter pack. This material accounting will be recorded in the field book.
• A bentonite seal at least two feet thick will be placed immediately above the filter pack. The
method of bentonite seal placement shall be the same as for the filter pack. The bentonite
pellet seal will be hydrated either by pouring water or utilizing the tremie pipe with an
approximately equal volume of clean, potable water, and allowed to sufficiently hydrate. If
water is used, its source and the volume used will be documented in the field book. The
level of the top of the bentonite seal will be verified by tag-method measurement prior to
grouting.
• To grout the remaining annular space, a side-discharging tremie pipe will be maintained
three feet above the bentonite seal and will be used to slowly place the cement/bentonite
grout mixture. The HSAs will be pulled incrementally during the grouting procedures to limit
borehole collapse. Grout will be pumped into the annulus through the tremie pipe until
undiluted grout flows from the borehole at the ground surface. The grout will be allowed to
cure for at least 24 hours prior to development.
All soil and fluid cuttings that result from drilling will be containerized in a 55-gallon drum(s). Based
upon the analytical results of the soil sample taken from the boring, the containerized material will
either be: 1. Spread on-site (if the soils do not contain contaminants in levels greater than the
DENR Inactive Hazardous Sites Branch's (IHSB's) standards), 2. Transported to a subtitle D landfill
(if soils are greater than the IHSB limits, but non-hazardous), or 3. Transported to a certified
hazardous disposal facility/landfill (if soils exceed IHSB limits and are classified as hazardous).

Monitoring Well Development
After installation and a minimum 24-hour period for grout curing, the monitoring well will be
developed using either surge-and-bail or swab-and-pump methods, depending on well depth and
yield. The development method should include methods of moving water both inward, from the
formation into the screen, and outward, from the screen into the formation material. The water
level and height of sediment in the well should be measured and recorded in the field log book prior
to development.
In most cases, the initial well development method will be hand-bailing to remove accumulated
sediment in the well. The bailer will be allowed to fall freely through the well past the water surface
until it strikes the bottom of the well. The bailer will be raised to the surface vigorously to create a
high-action level of water movement. This free fall and rapid removal will provide some surging
action to the filter pack and proximal formation material. To enhance the removal of sediment, the
bailer should be intermittently agitated by rapid short upward strokes from the bottom of the well.
Bailing should be continued until the water is free from suspended sand-sized sediment.
A surge block may be needed to create a stronger surging action than the bailer does. If this is the
case, the surge block and the bailer will be used in conjunction with one another. After utilizing the
surge block for a short period of time, the sediment that entered the well as a result of the surging
will be removed with the bailer, as described in the previous paragraph. The surge block will be
composed of inert material that will not affect the water quality in the well. Caution will be
employed to ascertain that the block can move freely up and down the inside of the well without
obstructions. The vertical action of the surge block will be accomplished manually. Care will be
taken in the length of the strokes, the velocity of the up-and-down movement, and the duration of
each surge block cycle. If the surging action is too vigorous for the well construction and formation
characteristics, then the activity can be detrimental to the well integrity.
Water discharged from the monitoring well(s) during the development process will be containerized
in a SS-gallon drum(s). Based upon the analytical results of the water samples taken from the well,
the containerized material will either be: 1. Spread on-site (if the water samples do not contain
contaminants in levels greater than the DENR Inactive Hazardous Sites Branch's (IHSB's)
standards), 2. Transported to a certified non-hazardous disposal facility (if water samples are
greater than the IHSB limits, but non-hazardous), or 3. Transported to a certified hazardous disposal
facility/landfill (if water samples exceed IHSB limits and are classified as hazardous).
Development criteria will include the stabilization of standard field parameters. These criteria will
be refined, based on the initial results at each site, with the objective being to achieve minimum
turbidity in all wells. During the pumping stage of development, pH, specific conductivity (SC),
dissolved oxygen (DO), oxidation-reduction potential (ORP), temperature, and turbidity will be
measured generally once for every well volume removed. For each monitoring well, the well
development and measurement of field parameters will be documented on a monitoring well
development and sampling log.
Monitoring Well Groundv·1ater Sampling
Groundwater sampling will be conducted by personnel properly trained in procedures for collecting,
labeling, packing, and shipping the samples.
The monitoring well will be purged using low-flow techniques in accordance with the procedures
described in Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures United States
Environmental Protection Agency (EPA), Groundwater Issues (April 1996). New polyethylene tubing
will be used to purge and sample each well. During purging, the pH, SC, DO, ORP, turbidity, and
temperature will be measured and recorded every three minutes. Well purging will continue until
these parameters stabilized (three successive readings in which pH +/-0.1 unit; SC +/-3 percent;
temperature, DO and turbidity+/-10 percent; and ORP +/-10 millivolts). After parameters have
stabilized, groundwater samples will be collected.

Buncombe County, North Carolina
Dear Ms. Proctor:
On behalf of Enka Partners of Asheville, LLC (Enka Partners), Altamont Environmental, Inc.
(Altamont) has prepared this confirmation sampling and analysis work plan in general accordance
with the North Carolina Department of Environment and Natural Resources (DENR), Division of
Waste Management (DWM), Hazardous Waste Section (HWS) Generator Closure Guidelines dated
June 18, 2008. In addition to the guidance, Altamont reviewed the following reports to prepare this
work plan:
• A&D Environmental, Inc., April 6, 2010, Site Specific Material Sampling and Characterization
Plan
• A&D Environmental, Inc., May 6, 2010, Response to Comments Made by NC DENR Regarding
Initial Site Sampling Plan as Required by Notice of Violation Docket # 2010.067

Site [email]
Background
The subject property is a portion of the former BASF facility located off of Sand Hill Road in the Enka
community of Buncombe County, North Carolina. The subject property was purchased by Enka
Partners from BASF. Enka Partners is in the process of redeveloping the property. A site location
map is attached as Figure 1.
As part of the redevelopment, Enka Partners demolished several buildings. Inside one of the former
buildings were four, 150,000-gallon aboveground, open-top storage tanks. The tanks presumably
contained sodium hydroxide (NaOH) based upon labels that were painted on the tanks and
subsequent pH measurements collected by A&D Environmental, Inc. (A&D).
Enka Partners removed and sold as a usable product the contents of one of the tanks to a truck
wash company. Following removal of the tank contents, Enka Partners demolished the tank and
stockpiled residual solids, debris, and waste materials on site.
The HWS inspected the subject property and observed the areas of stored waste as well as the
results of Enka Partners activities. Following their inspection, the HWS issued an Immediate Action
Ms. Roberta Proctor
November 2, 2010
Page 2 of 4
P:\Enka Partners\Correspondence\Confirmation Sampling Work Plan Final.Doc
Notice of Violation, Docket #2010-067 (NOV) on March 24, 2010. The HWS requested that Enka
Partners take various actions to properly characterize and dispose of waste materials located on
the subject property.
Enka Partners hired A&D. A&D prepared and submitted a sampling plan to the HWS to satisfy the
material and waste characterization components of the NOV. After submittal and approval of the
site specific sampling plan by the HWS, A&D mobilized to the site and completed the sampling and
waste characterization activities. Those activities are described in greater detail on the following
pages.
Now that the waste has been characterized, A&D plans to properly dispose of the waste in
accordance with local, state, and federal regulations. Following waste removal and disposal,
Altamont will complete confirmation sampling activities. The confirmation sampling activities are
described on the following pages.
Areas of Concern
Altamont understands that the HWS has requested confirmation sampling in four areas. The four
areas can be described as follows:
• Tank area associated with a former building [Sodium Hydroxide (NaOH)]
• Former stockpile area
• Area of ponded water
• Container area associated with a former building
The locations of the four areas are indicated on Figure 2.
Objective
A&D collected samples from waste materials and sediments. Constituents were identified in A&D’s
samples at concentrations in excess of HWS soil screening levels. The objective of the work
described within this plan will be to determine if these constituents have impacted the underlying
soil in excess of regulatory standards.
Review of Existing Data
Altamont reviewed A&D’s waste characterization sample laboratory analytical results. A&D
collected samples from waste materials located in the previously described four areas of concern.
A&D had samples analyzed as follows:
• Tank Contents—Samples were analyzed for pH and alkalinity and for Resource Conservation
and Recovery Act (RCRA) metals in accordance with the Toxicity Characteristic Leaching
Procedure (TCLP)
• Former Stockpile Material—Samples were analyzed for pH and Asbestos and for RCRA
metals using a total waste analysis (results reported in milligrams per kilogram)
• Water Within and the Sediments Beneath the Area of Ponded Water—Water samples were
analyzed for pH and RCRA metals using a total waste analysis (results reported in milligrams
per liter) and sediment samples were analyzed for RCRA metals in accordance with the
Toxicity Characteristic Leaching Procedure (TCLP) and using a total waste analysis (results
reported in milligrams per kilogram)
Ms. Roberta Proctor
November 2, 2010
Page 3 of 4
P:\Enka Partners\Correspondence\Confirmation Sampling Work Plan Final.Doc
• Container Contents—Liquid samples were analyzed for pH, polychlorinated biphenyls (PCBs),
volatile organic compounds (VOCs), and RCRA metals using a total waste analysis (results
reported in milligrams per liter)
The TCLP sample results were multiplied by a factor of 20 consistent with the conventional practice
for converting between total waste analyses in milligrams per kilogram and TCLP analyses in
milligrams per liter. Altamont compared the converted TCLP results as well as the available total
waste analyses results to HWS soil screening levels. Additionally, Altamont compared the pond
water sample results to the groundwater standards published in Title 15A subchapter 2L .0202 of
the North Carolina Administrative Code (2L Standards). Based upon Altamont’s review, the
following constituents of concern were identified in the following areas and matrices:
• Tank area associated with a former building [Sodium Hydroxide (NaOH)]
° Tank 1—Arsenic and Mercury
° Tanks 2 and 3—Mercury
• Former Stockpile Area—Lead, Mercury, Chromium, and Cadmium
• Area of Ponded Water
° Arsenic, Mercury, and Cadmium in Soil
° Arsenic, Barium, Lead, Mercury, and Chromium in Water
• Container area associated with a former building—Chromium and Toluene
Confirmation Sample Collection
After the stockpiled waste products are removed, Altamont will implement a confirmation sampling
program. Altamont will contact North Carolina “one call” to locate publically owned utilities.
Additionally, Altamont will develop a site specific health and safety plan for the protection human
health and safety during the implementation of the work.
Altamont will utilize a North Carolina licensed drilling contractor to install ten temporary borings
using direct-push technologies at the sample locations indicated on the attached Figure 2. The
borings and the proposed sample analyses are summarized on the attached Table 1.
Altamont will direct the drilling contractor to install each boring to the necessary depth for
collection of samples. The drilling contractor will use direct-push sampling equipment to collect
continuous undisturbed cores from each borehole. The drilling contractor will collect the
undisturbed cores in plastic sleeves. Altamont will record the estimated soil origin, consistency,
color, grain size, and other ancillary descriptions of the soil (e.g. staining and moisture content) on
soil boring logs.
The borings will be advanced to two feet below ground surface (not including the thickness of any
remaining building and tank foundations). Altamont will collect biased soil samples from the
unsaturated zone based upon the presence of residual contamination and a visual evaluation of
characteristics like staining and odor. All samples will be placed in a cooler on ice to await delivery
to the laboratory.
Sample Analyses
Altamont will utilize a laboratory appropriately certified by the State of North Carolina to analyze
the samples. The proposed samples will be analyzed for the constituents summarized on Table 1.
The following analytical methods will be used:
• Metals (except Mercury)—Environmental Protection Agency (EPA) Method 6010
