EXPLANATION OF SIGNIFICANT DIFFERENCE
OPERABLE UNIT 3 REMEDIAL ACTION
FCX-ST A TES VILLE SUPERFUND SITE
STATESVILLE, IREDELL COUNTY, NORTH CAROLINA
. 1.0 INTRODUCTION
Section 117( c) of the Comprehensive Environmental Response, Compensation, and
Liability Act (CERCLA) and Section 300.435 (c)(2)(i) of the National Contingency Plan (NCP)
require that the Environmental Protection Agency (EPA) publish an Explanation of Significant
Difference (ESD) when significant changes in a Superfund remedy occur after the Record of
Decision (ROD) is signed. The purpose of this ESD is to notify all parties of concern that the
EPA is enacting significant changes to the Operable Unit 3 (OU3) Remedial Action at the FCX-
Statesville Superfund Site based on' information received subsequent to the signing of the OU3
ROD in 1996. EPA-Region IV believes these significant changes will enhance the effectiveness
of the OU3 remedy.
A copy of this ESD will be added to the FCX-Statesville Site Administrative Record _and
Information Repository. The Administrative Record and Information Repository ca_n be 'found in
the Iredell County Library located in Statesville, North Carolina, and in the Information Center at
the EPA-Region IV Office in Atlanta, Georgia (both addresses are provided in Section 8.0 of
this document). The public is encouraged to review the Administrative Record at either of these
locations.
EPA is the lead agency and the North Carolina Department of Environment and Natural
Resources (NCDENR) is the support agency for the FCX-Statesville Superfund Site.
I.I: Purpose for Issuing This ESD
In 1996, EPA issued the OU3 ROD which selected soil vapor extraction (SVE) and air
sparging (AS) to address areas on and around the former Burlington property with high levels of
VOCs in soil and groundwater, respectively, and Monitored Natural Attenuation (MNA) to
address areas on and around the former Burlington property' with .low levels .of VOCs in
groundwater. The MNA portion of the OU3 remedy began in 1998, and the AS/SVE portion of
the remedy became operational in 200 l. The OU3 ROD also stipulated that if the remediation
levels for groundwater were not attained using SVE, AS, and MNA, the OU3 remedy should be
re-evaluated.
Groundwater monitoring on and around the former Burlington property has been
conducted on a semi-annual basis, as required by the OU3 ROD. Groundwater sampling data
collected during the OU3 Remedial Action indicate that natural attenuation is occurring within
the areas being addressed with the OU3 Remedial Action. However, there are areas of the VOC
plume on and around the former Burlington property where possible upward trends or no
significant or conclusive trends in VOC concentrations have been observed. For example, VOC
-3-
•
concentrations at monitoring well locations located north of the forme~ Burlington property
appear to have been increasing from 1998 (the year monitoring begani through 2001. However,
more recent data indicate that there are no conclusive trends. By comparison, VOC
concentrations (in particular PCE, TCE, and cisl,2-DCE) at monitoring well locations located
south of the former Burlington property have exhibited possible downward trends since 2002.
Groundwater data from a monitoring well located immediately south of the former textile plant
indicate VOC concentrations have not changed significantly in that area.
The apparent trend of increasing VOC concentrations at certain areas within the
groundwater contamination plume on and around the former Burlington property prompted EPA,
NCDENR, and El Paso Natural Gas Company (EPNG) to initiate discussions about potential
options for enhancing the existing OU3 remedy. EPA believes, and NCDENR concurs, that
Accelerated Natural Attenuation (ANA), involving the injection of electron donor into the
aquifer to enhance the natural attenuation of VOCs, is a viable treatment option worthy of
consideration for enhancing the existing OU3 remedy.
2.0 SITE LOCATION AND DESCRIPTION
The FCX-Statesville Superfund Site, located in the city of Statesville, North Carolina,
consists of three operable units (OUs). Figure I shows the general location of the former FCX
· property and former Burlington Industries property. EPA has been conducting the OU I
Remedial Action since 1998 to addre~s pesticide and VOC contamination in groundwater on the
former FCX property and south thereof. In 2001, EPA completed the OU2 Remedial Action to
address pesticide soil contamination on the former FCX property. The MNA portion of the OU3
Remedial Action has been conducted by El Paso Natural Gas Company (EPNG) since I 998, and
the AS/SVE portion of the OU3 Remedial Action has been conducted since 2001, to address
VOC contamination on and around the former Burlington property.·
The primary contaminants of concern (COCs) in· soil and groundwater currently being
addressed during the OU3 Remedial Action with AS, SVE, and MNA include the VOC
tetrachloroethene, also referred to as perchloroethene (PCE), and its daughter products. VOC
contamination has been identified in the shallow saprolite, intermediate weathered bedrock, and
the fractured bedrock portion of the aquifer.
Soil samples collected during the OU3 RVFS identified VOCs, inorganics, an.d polynuclear
aromatic hydrocarbons (PAHs) in on-site soil on the former Burlington Industries property.
Surface water and sediment samples collected from an intermittent stream originating from a
seep to the north of the former textile plant during the OU3 RI/FS also contains VOCs, several
inorganic constituents, and low levels of polychlorinated biphenyls (PCBs).

However, the Baseline Risk Assessment indicated the concentrations of VOCs, inorganics, and
PCBs in soil, surface water, and sediment posed no direct contact risk to human beings on and
around the former Burlington property. The OU3 ROD did not require remediation of soil,
surface water, and sediment to address inorganics, P AHs, or PCBs. ·
3.0 SUMMARY OF SITE (RELATED TO OU3)
The former Burlington textile plant was originally constructed in 1927. From 1955 to
1977, the plant was operated by Beaunit Mills. In 1967, Beaunit became a subsidiary ofEPNG.
In April 1977, Beaunit sold substantially all of its assets, including the textile plant, to Beaunit II,
Inc. As part of the transaction, Beaunit II changed its name to the Beaunit Corporation. In July
1978, the plant was sold by the Beaunit Corporation to Beaunit Fabrics Corporation. In 1981,
Burlington Industries, Inc. purchased certain assets, including the textile plant, from Beaunit
Fabrics.
4.0 SUMMARY OF OU3 REMEDY
EPA issued the OU3 ROD in 1996 to address VOC contamination in soil and
groundwater on and around the former Burlington Industries property. The OU3 remedy
involves the use of SVE to address high VOC concentrations in soil located beneath the former
textile plant, and air sparging to address high VOC concentrations in groundwater located
beneath the former textile plant. MNA was also included in the OU3 remedy to address areas
with lower VOC concentrations in groundwater on and around the former Burlington property.
Institutional controls were included in the OU3 remedy to insure that there is no human exposure
to Site-related VOC contamination in groundwater on the former Burlington property.
The AS/SVE treatment system irivolves a system of wells designed for VOC removal
from soil and groundwater beneath the former textile plant, and automatic, 24-hour a day
operation. The network of wells is concentrated i_n areas with the highest levels of VOC
contamination on the former Burlington property. All wells are piped to a central control
location located within the former textile plant. The AS/SVE system was constructed and
became operational in 200 I.
The MNA portion of the OU3 remedy, which began in 1998, includes groundwater
sampling and analysis for VOCs, as well as parameters that are indicative of on-going VOC
degradation processes.
The OU3 remedy also specified that contingency measures and goals may.be needed to
supplement or replace the remedy to prevent further migration of the pl'ume, or attain State or
Federal groundwater standards.
-6-
•
5.0 DESCRIPTION OF SIGNIFICANT DIFFE~NCES
The OU3 ROD selected MNA as the remedy for areas on and around the former Burlington
property with low levels of voes in groundwater. The OU3 ROD stipulated that if MNA would
not result in the attainment of the State or Federal groundwater standards in those areas, the
remedy should be re-evaluated.
I
The semi-annual groundwater sampling required as part of the OU3 Remedial Action has
shown that the margins of the voe plume appear effectively stable _and relatively unchanged.
The presence of PeE daughter products within the voe groundwater plume, including
trichloroethene (TeE), cis-1,2-dichloroethene ( cDeE), and ethene, provide primary evidence
that reductive dechlorination continues to occur in most areas of the Site. The presence of PeE
daughter products, and a plume that is not expanding, are indica_tions that natural attenuation is
occumng.
While groundwater sampling data indicate that natural attenuation is occurring within the
areas being addressed with the OU3 Remedial Action, there are areas of the plume, particularly
within the interior or mid-portion of the voe plume located north of the former Burlington
property, where possible upward trends or no significant or conclusive trends in voe
concentrations have been observed. For example, voe concentrations at W-l 9s, W-20s, and
W-30i in the interior of the plume appeared to have been increasing from 1998 (the year
monitoring began) through 2001. Figure 2 shows the location of the monitoring wells. However,
more recent data indicate that there are no conclusive trends. Within the mid-portion of the
southe.m voe plume (W-29i), the PeE, TeE, and cisl,2-DeE concentrations have exhibited a
possible downward trend since 2002. Immediately south of the former textile plant (W-5i), voe
concentrations have not changed significantly.
The lack of significant downward trends in voe concentrations in areas of the
groundwater plume away from the source area treatment zone indicates that the OU3 ROD
remediation levels may not be achieved within a reasonable time fram·e in these areas. Since
2003, EPA, NeDENR, and EPNG have discussed possible options for enhancing the OU3
remedy. EPA believes, and NCDENR concurs, that the use of ANA, involving the injection of
electron donors into the aquifer to accelerate natural attenuation, and possibly the addition of
microbes, should speed up the process ofVOe groundwater remediation at the Site.
The following paragraphs describe the significant differences EPA believes are appropriate
for the OU3 remedy at the Site.
5.1: Difference No. 1: Accelerated Natural Attenuation (ANA)
The OU3 remedy will use AS/SVE to address areas of the Site with devated concentrations
of voes. The OU3 remedy will also use MNA to address ·areas of the Site with lower
concentrations of voes. In addition to the use of AS, SVE, and MNA, this ESD provides for
-7-
• •
the use of ANA in selected areas throughout the Site, as needed, where MNA is not significantly
reducing voe concentrations. The delivery strategy for ANA is a phased approach consistent
with the approach used since 2001 for implementation of AS/SVE in the source area.
Hydrogeological variability is an issue at the Site that must be taken into account during
design planning. ·The design for ANA will incorporate a phased approach that ensures flexibility
in responding to Site hydrogeological conditions. As planned, the conceptual design will be
refined based on the Pre-Design Investigation (POI) results. Evaluation of the PD! results is on-
going.
FIGURE 2 -MAP SHOWING THE
LOCATIONS OF MONITORING WELLS
. "'•

(j ,,. •· ,, I •. ,,,
z;----
The objective of using ANA io enhance the OU3 remedy at this Site is to accelerate the
natural attenuation of voes by injecting electron donor and, possibly, bacteria (i.e., microbial
injection) into the groundwater. Various products are being considered as potential electron
donors including HRe-X (or related product) and emulsified soluble oil.· Either or both may be
selected for use, depending on further analysis of Site conditions during the design. Microbial
injection is a possible option for a later application ifnative microbes are not present in sufficient
numbers to reduce contaminant concentrations.
The locations for injection points will be selected during the design to focus delivery of
electron donor and/or bacteria into portions of the aquifer with sufficient porosity and
permeability to allow distribution of the materials. The conceptual design for ANA at the Site
involves the use of up to three rows of injection wells at locations north of the former textile
-8-
•
plant, and one row of injection wells at a location south of the former textile plant. See Figure 3.
Evaluations of POI data are on-going to determine the exact locations o(injection points and/or
welis, injection depths, and injection/delivery methods.
The conceptual design for ANA at the Site involves the use of a phased approach. As part
of the ANA design, criteria will be developed to guide the decision-making process between
phases. The conceptual phases are described as follows:
Conceptual Phase I: As shown in Figure 3, Phase I will involve injection of electron donor
in two rows of injection wells (NI and N2) across the area with the highest PCE
concentration located north of the former Burlington property. Groundwater would be
sampled to evaluate the effectiveness of ANA.
Conceptual Phase II: Phase II will involve injection in the northern plume in two or three
rows (NI, N2, and N3), and the southern plume in one row (SI). The locations, depths,
amounts, and frequencies of injection applied during Phase II wiH depend on an evaluation
of the Phase I analytical results. The OU I groundwater treatment system should be shut
off prior to injection in the southern plume. Groundwater would be sampled to evaluate the
effectiveness of ANA.
Possible Subsequent Conceptual Phases: If needed, subsequent phases will involve
injection in the areas of the Site not addressed with Phases I and II, including, but not.
limited to, the former FCX property. The locations, depths, amounts, and frequencies of
the injections will be subject to adjustment based on groundwater monitoring results
following Phases I and II. Injections would be discontinued at a point in time when MNA
could reasonably be used to finish the groundwater remediation.
Initial cost estimates for enhancing the OU3 remedy with ANA-in the areas north of the
former textile plant assumes Phase I injection only at the injection points for NI and N2; and one
year of monitoring, analysis and reporting. Additional cost estimates will be developed and
revised as the design proceeds. The design and associated cost estimate will include a specific
number of wells, amount of injected material, etc. based on evaluation of the pre-design data.
Following the implementation of Phase II described above, if it is determined that
groundwater to the north and south of the former textile plant need additional treatment with
ANA, additional injection may be implemented at that time. Table I presents the cost estimate
for conceptual Phase I. A present worth calculation was not performed for the cosi estimate.
Although not estimated in Table I, the costs of each additional phase of injection are anticipated
to be similar to the Phase I cost estimate. Repeated injections are anticipated; however, locations
and numbers of repetitions cannot be anticipated at this time.

· Annual monitoring and reporting costs are assumed to be similar for the duration of the OU3
Remedial Action, although they may increase or decrease depending on the number of locations
that require continued injections.
5.2: Difference No. 2: Non-Site-Related Contaminants of Concern
The Baseline· Risk Assessment (BRA) for OU3 identified a. number of Potential
Chemicals of Concern (PCOCs), including IO YOCs, the inorganics aluminum, arsenic, barium,
iron, lead, and manganese, and the compound bis(2-ethylhexyl)phthalate. EPA included these
' PCOCs into the OU3 ROD as Contaminants of Concern (COCs). EPA has re-evaluated the list
of COCs since the OU3 ROD was issued in 1996 to determine if it needs to be updated or
modified. Based on the re-evaluation, EPA has decided to remove the inorganics aluminum,
arsenic, barium, iron, lead, manganese, and the compound bis(2-ethylhexyl)phthalate from the
list ofCOCs.
Arsenic was identified as a PCOC for several reasons: 1) the average of the detected
concentrations (9.8 µg/1) exceeded the risk-based screening value (0.045 µg/1), 2) the average of
the detected concentrations (9.8 µg/1) exceeded twice the background concentration (1.7 µg/1),
and 3) the exposure point concentration of8.l µg/1 resulted in a potential risk from ingestion and
-10-
• .:
inhalation exposure of 2.2E-4. However, since arsenic was not detected at concentrations above
the Federal MCL and State groundwater standard of 50 µg/1, and because EPA does not consider
arsenic to be Site-related, EPA believes arsenic should be removed as a COC for the OU3
remedy.
Barium was identified as a PCOC in the BRA for the following reasons.' Barium was
detected in 9 groundwater samples at concentrations ranging from 19.9 µg/1 to 1,040 µg/1, with
an exposure point concentration of 280 µg/1. This results in a Hazard Index from ingestion
exposure of0.11, which contributed to a pathway Hazard Index of 1.2. However, since barium
was not detected at concentrations above the MCL (2,000 µg/1), and because EPA does not
consider barium to be Site-related, EPA believes barium should be removed as a COC for the
OU3 remedy.

Bis(2-ethylhexyl)phthalate was identified in one groundwater sample during the Remedial
Investigation at a concentration of 67 parts-per-billion (ppb). Since this concentration exceeds
the risk-based screening value for bis(2-ethylhexyl)phthalate of 4.8 ppb, this constituent was
included · in the BRA as a COC. However, the location of the well in which bis(2-
ethylhexyl)phthalate was identified is on the former Carnation property. Bis(2-ethylhexyl)-
phthalate was not identified on the Burlington property in soil or groundwater. Therefore, EPA
-I I -
•
does not consider the groundwater sample with bis(2-ethylhexyl)phthalate to be related to prior
operations at the former Burlington property. For this reason, EPA believes bis(2-
ethylhexyl)phthalate should be removed as a COC for the OU3 remedy.
The inorganics aluminum, iron, lead, and manganese were also included in the OU3 ROD
as COCs. EPA believes these inorganics are not Site-related, and are present in groundwater as
naturally-occurring minerals. For this reason, EPA believes aluminum, iron, lead, and manganese
should be removed as COCs for the OU3 remedy.
Table 2 shows an updated list of COCs for the amended OU3 remedy, as we_ll as the
remediation level for each of the VOCs listed. All groundwater remediation levels provided in
Table 2 are either North Carolina Ground Water Quality Standards (NCGWQS) NCAC 2L.0202,
or EPA Maximum Contaminant Levels (MCLs). Note that a few of the VOC remediation levels
listed in this document have been updated from the remediation levels in the 1996 OU3 ROD .

The OU3 ROD identifies EPl analyticai Method 8240 to be used for VOC analysis,
Method 8080 for pesticides, Method\6010 for metals, and Method 8270 for phthalate scan. EPA
believes the list of analytical methods required for the OU3 remedy needs to be updated to allow
use of the most curren·t SW-846 Methods. Use of the most current SW-846 Methods will take
advantage of improvements in analytical technology as the remediation progresses.
-12-
• •
5.4: Difference No. \4: Distinction between the Original OU I Remedy, the
Amended OU! Remedy, the Original OU3 Remedy, and the Modified OU3
Remedy
A distinction needs to be made between the original OU I remedy and the Amended OU I
remedy (based on the OU! ROD !Amendment). The major components of the original OU!
ROD included extracting and trediing groundwater at the FCX property, and to the south of the
FCX property, contaminated with metals, pesticides, and VOCs at levels exceeding Federal
Maximum Contaminant Levels (MCLs) or North Carolina Groundwater Standards. The original
OU! remedy also included long-t~rm groundwater monitoring. By comparison, the amended
OU! remedy will address the rem1aining pesticide groundwater contamination associated with the
former FCX property using moniiored natural attenuation. The amended OU I remedy will not . I address metals and VOCs in groundwater on the former FCX property and south thereof.
Similarly, a distinction ne~ds to be made between the original OU3 remedy and the
modified OU3 remedy (based on t,his ESD). Since 2001, the AS/SVE remedy has been used to
address VOC groundwater and soil contamination, respectively, on and around the former
Burlington property with the highbst VOC concentrations. Groundwater. monitoring and MNA
have been used since 1998 to addr~ss those areas on and around the former Burlington property
' with lower VOC concentrations. By comparison, the modified OU3 remedy, based on this ESD,
will involve the use of AS, SVE, ind the conceptual phases of ANA described in Section 5.1 of
this ESD, to address the highest cdncentrations ofVOCs at the Site. MNA will continue to be
used to address areas with low levbls ofVOC groundwater contamination, including locations
north of the former Burlington property, am:! on the former FCX property and south thereof.
I
6.0 EVALUATION OF PROPOSED REMEDY BASED ON NINE EVALUATION
CRITERIA
Short-term effectiveness -Enhancing the existing OU3 remedy with ANA should have positive
short-term effects on the groundwater quality at the Site. Groundwater monitoring will
determine the level of effectivenesJ over the short-term.
Reduction of Toxicity, Mobility, J Volume Through Treatment -Enhancing the existing OU3
remedy with ANA will reduce the toxicity and volume of the VOCs in groundwater in a shorter
amount of time than MNA only. G~oundwater monitoring will determine if the addition of ANA
affects the mobility of the VOCs inlgroundwater. ·
Long-term Effectiveness and PermJnence -Enhancing the OU3 remedy with ANA should
increase the long-term effectiveness and permanence of the OU3 remedy. The addition of ANA
should reduce the amount of remediation time required to meet federal and State drinking water
I standards for VOCs at the Site. I . .
-13-
• •
Compliance with Applicable or Relevant and Appropriate Requirements With a few
. exceptions. all existing applicable chemical-, action-, and location-specific requirements in the
OU3 ROD will not change with the addition of ANA to the OU3 remedy. The remediation
levels for a few VOCs have changed from the levels in the 1996 OU3 ROD.
Protection of Human Health and the Environment -EPA believes enhancing the existing OU,3
remedy with ANA will continue to provide adequate protection of human health and the
environment, and will achieve the federal and State drinking water standards in a shorter amount
of time.
Implementability -Enhancing the existing OU3 remedy with ANA should be easy to implement.
Typical applications require conventional materials-handling equipment, and are readily
available. Furthermore, ANA should require a shorter treatment time than MNA alone.
Cost -The estimated cost of conceptual Phase I for enhancing the OU3 remedy with ANA is
$ I ,227, 139 (a present worth calculation was not performed). The cost benefit of adding ANA
may not be realized in the short-term. However, EPA believes enhancing the OU3 remedy with
ANA will reduce the amount of time required for remediation, thereby reducing the overall cost
of the OU3 remedy.
State Acceptance -NCDENR agrees with EPA that the changes proposed in this ESD, including
ANA, modifying the list ofCOCs, and modifying the analytical methods, appear to be
reasonable for the following reasons: I) while ANA is a relatively new technology, ANA has
been used successfully at other remediation sites for various remediatiOl) wastes including PCE
and its daughter products; 2) the short-term effectiveness of ANA will be monitored through
groundwater monitoring; and 3) the use of ANA increases the State's level of confidence that the
OU3 remedy will achieve the remediation levels established in the OU3 ROD in a reasonable
timeframe. EPA-Region 4 and NCDENR agree that the remediation levels established for VOCs
in the OU3 ROD and amended by this ESD should be achieved in less time using the remedy
changes proposed in this ESD.
Community acceptance -EPA held a public meeting in Statesville, North Carolina, on October
27, 2005 to discuss the proposed changes to the OU! remedy. The second halfofthemeeting.
was devoted to a discussion of the OU3 remedy. Based on the limited amount of feedback from
the citizens who ·attended the public meeting, EPA believes the local community agrees with the
proposed changes to the OU3 remedy. ·
EPA held a second public comment period from April 05, 2006, fo May 04, 2006, and a
second public meeting on April 11, 2006 to discuss changes to the OU I ROD Amendment made
by EPA after the first public comment period. No public comments were received from the local
community during the first comment period, and no one from the local community attended the
public meeting. EPA did receive a few comments from El Paso Natural Gas Company. EPA's
responses to El Paso's comments are included in the Responsiveness Summary as Appendix B to
the OU 1 ROD Amendment.
-14-
•
As required by Section 300.435(2)(i)(B) of the National Contingency Plan (NCP) and
CERCLA Section 117, EPA published a public notice in the Statesville Record and Landmark.
7.0 AFFIRMATION OF STATUTORY DETERMINATIONS
EPA-Region 4 and NCDENR believe that the changes proposed for the OU3 remedy will
increase the protectiveness of human health and the environment, comply with Federal and State
' . requirements that are applicable or relevant and appropriate (ARAR) for this Remedial Action,
and are cost-effective. With the exception of a few VOC remediation levels changed from the
OU3 ROD; all ARARs established in the 1996 ROD are unchanged by this ESD. In addition, the
changes described in this ESD utilize permanent solutions and alternative technologies to the
maximum extent practicable for this Site. ·

EPA provided public notice about the OU! ROD Amendment on October 21, 2005. EPA
held a public meeting on October 27, 2005, to discuss both the OU! ROD Amendment. The
OU3 ESD was also discussed during the meeting. A total of six (6) people attended the meeting,
and EPA did not receive any comments from the public during the 30-day comment period.
EPA provided a second public notice for the OUI ROD Amendment ori April 5, 2006,
and EPA provided a public notice for the OU3 ESD on April 2, 2006. EPA held a second, 30-
day comment period from April 05, 2006, to May 04, 2006, and a second public meeting on
April 11, 2006. No public comments were received from the local community during the second
comment period, and no one from the local community attended the second public meeting.
However, EPA did receive comments from El Paso Natural Gas. EPA's responses to El Paso's

• •
comments are included in a Responsiveness Summary as Appendix B to the OU! ROD
Amendment. Based on the limited amount of feedback from the local 'community, EPA believes
the local community agrees with the proposed changes to the OU3 remedy.
As required.by Section 300.435(2)(i)(B) of the National Contingency Plan (NCP) and
CERCLA Section 117, EPA published a public notice in the Statesville Record and Landmark
both comment periods and both public meetings.
The NCDENR agrees with the proposed changes to the OU3 remedy. NCDENR's

FCX Statesville NPL Site
This represents a partial response by me to the RPs' 7 /22/99 comments
on EPA's 4/98 draft ESD.
The RPs' proposed second paragraph of Section 4.0 o the draft ESD
asserts that the Affected Area is supplied with city water and that
there are no private or community wells there. If the RPs have not
reliably documented those two assertions, they should be required to
do so.
That same proposed paragraph states that "the City qf Statesville
requires properties served by city mains to use city water rather than
well water ... " Presumably reference is to Section 23-276(a) of
Statesville's Code, at least as it read as of a 9/98 supplement, which
states, "Each lot shall have separate and independent water and sewer
service connection if mains are available. If a lot cannot be served
as provided for in this chapter, wells and/or septic tanks may be
installed only if authorized byt he county health department." Let's
talk about whether the proposed ESD paragraph is a fair summary of the
ordinance.
I also have information on the enforcement of Statesville's Code,
which we can discuss. And, if the RPs' draft paragraph is in
. principle acceptable, we should discuss, as previously noted, the
· addition of requirements for periodic certification of the' absence of
wells and of any other contra-indicated activities on the affected
properties.

I received a copy of a letter from Nancy Prine of El Paso Energy to
Ken Mallary, EPA RPM re an ESD on institutional controls. Nancy
states that the enclosed draft ESD incorporates changes that reflect
conversations with you. The people you may have spoken to are
Jennifer Porter, El Paso's attorney, or George House, Burlington's
attorney.
The remedy at the site is air sparging on the hot spots (all on
Burlington property) and monitored natural attenuation (MNA) on the
rest of the ground water plume. Source control will be done by soil
venting.
The GW plume has migrated off site and affected several properties.
The institutional controls proposed at the site include restrictive
covenants only on Burlington's property. All affected properties are
located within the city and the city of Statesville (according to the
PRPs) requires properties served by the city to use city water. (No
info included if this is true or if the city checks to see that wells
are not installed now or at a later date.) I had requested info on
the city's ordinance, as you have, many times. My questions have been
if there is an ordinance against home wells how does the city
implement and enforce the ordinance. If the city does not have an
ordinance or if enforcement is not there, the PRPs could check the
properties on a semiannual basis for any gw wells.
I have a problem with the revised ESD. It is not, as presented,
protective of the citizens of the affected area. A drinking water
well could be installed and no one would know about it. The ESD goes
on to discuss notification of the affected parties. This is required
by the GW Section for all MNA sites. The notification is by certified
mail and is one time thing.
I will be here tomorrow but out next week.
If I could get your input before I comment on the ESD. Let me know
the easiest way to get the revisions to you.

ESD to the ROD
Dear Ken,
As we have discussed previously, El Paso and Burlington Industries have comments on the ESD
proposed by EPA in April, 1998.
The institutional controls portion of the remedy have been discussed with Mr. Rob Gelblum of
North Carolina Dept. of Environment and Natural Resources. The enclosed draft incorporates
changes that reflect my understanding of concepts discussed in these conversations. We are in the
process of preparing draft notice letters and I anticipate that these will be available for your review
in the near future.
A few other changes have been suggested that represent the present conditions at the textile facility,
or clarify our understanding of site conditions.
We appreciate your consideration of these comments and look forward to discussing them with you.
Sincerely,

Insert for Section 4.0, second paragraph (page 3)
EPA has determined that restrictive covenants are not required at this time for other
properties that, based on sampling and groundwater flow modeling, are known or
calculated to be part of the Site. (Properties referred to hereafter as the "Affected Area").
The Baseline Risk Assessment ("BRA") concluded that contaminants detected at the Site
do not present a risk to human health or the environment in the Affected Area. This
conclusion is based, in principal part, on the absence ofreceptors. Properties in the
Affected Area are supplied with water by the City of Statesville, the City of Statesville
requires properties served by city mains to use city water rather than well water, and an
inspection found that, in fact, there are no private or community wells in the Affected
Area.
To maintain the conditions, on which the BRA is based, EPA has determined that
property owners in the Affected Area should be notified of the presence, known or
calculated, of contaminants in groundwater at the Site. BI and El Paso will be
responsible for providing the requisite notice to property owners in the Affected Area.

Re: Well Ordinance Issue -FCX Statesville Site
Thu, 13 May 1999 16:34:27 EST ,
Thanks for the info.
I have a few questions. Does DENR permit single use drinking water
wells (I didn't think so)? If the city issues a permit for well
installation for areas without city water, how do they determine if
city water is available? If no permit is needed, how does the city
know if a well is being installed? If a permit is needed, how do they
know if a person puts in a well without a permit? Do they check to
see if a person is using well water if city water is turned off? Are
there penalties for noncompliance?
Thanks,
Nile

' 4. Restrictive covenants can not be forced on any property,owner. The owner of the
property has to agree to have a restrictive covenant placed on their property. It is
desirable for Burlington Industries to have this covenant on their property as
institutional control is part of the remediation method. It is not as desirable for other
property owners to have _a restrictive covenant on their de~d. It is the responsibility
of Burlington Industries to contact adjacent property owner(s) and request that a
' restrictive covenant be placed on their property(s). The Division needs to concur on
any language contained in a restrictive covenant.
The State of North Carolina looks forward to working with EPA on the final remedy for the
