Director
The Division of Environmental Management has reviewed the subject
report as requested. The comments from our Water Quality,
Air Quality and Groundwater Sections are provideh below: ,,
Water Quality Sectio~!
I
The surface water standards in the study report of the subject
site are not consistent with 15NCAC2B, August 1990. Fites Creek
must meet these standards. No additional comments can be offered
at this time. However, if discharge to surface ~ater is anticipated,
appropriate permit(s) will need to be obtained.
Air Quality Section:
The Air Quality Section has no additional comments to offer.
Groundwater Section:
Section 2.3.3. of the subject study report should read "As shown
on table 2.1, Groundwater ARAR's are established !by North Carolina
Administrative Code Section: 15A NCAC 2L 'Classifications and Water
Quality Standards Applicable to the Groundwaters :of North Carolina'".
Section 2.4 contains several inaccurate statemen~s and should be
corrected as follows:

Groundwater Standards
' The state groundwater standards are estab~ished by North
Carolina Administrative Code Section: 15A NCAC 2L Rule .0202
with the intent to protect all groundwaters of the state, not
just permitted facilities, to a level of quality at least
as high as that required by the Standards! It is North Carolina
state law that groundwater quality be restored to the level of
the standards; therefore, the stringency of these standards
can not be subject to argument or discuss~on.

2.3.2 Surface Water Criteria
North Carolina Water Pollution Control Regulations
15NCAC2H regulate surface water quality. These rules specify that Fites
Creek, Class C, must meet the standards for all freshwaters. Federal Ambient
I
Water Quality Criteria are also considered as criteria to be considered for Fites
Creek. These standards are contained in 15NCAC2B and displayed on
Table 2.2.
2.3.3 Groundwater ARARs
As shown on Table 2.1, groundwater ARARs are
established by Federal Maximum Contaminant Levels. These rules indicate
that a present source of drinking water should meet the standards set out ih
the code.
Standards are distinctly different from criteria. Standards
are regulatory-based values which are enforceable under certain conditionJ.
Standards are used to establish ARARs. Criteria are values developed froJ
research which are not ARARs but are to be considered when establishing
remedial objectives.
Table 2.3 contains a summary of standards and criteria for •
drinking water that are health based. Federal and State drinking water
standards are established for public water supplies.

2.1_ SPECIFIC REMEDIAL OBJECTIVES FOR GROUNDWATER
Table 2.3 presents a summary of drinking and
groundwater standards and criteria which were considered for use in
establishing groundwater remedial objectives. Federal water quality crite -ia -I
and maximum contaminant level goals (MCLGs) were also considered. Since
I maximum contaminant levels have been established for most constituents,
the use of Federal water quality criteria would not be relevant and approdriate
for a current or potential drinking water supply. Criteria are generally
established for the protection of aquatic life. North Carolina has promulgated
drinkin water and roundwater standards. The roundwater standards lre
in some cases more stringent than the North Carolina drinking water
standards or federal MCLs. The State groundwater standards were intended
to apply to permitted facilities rather than unpermitted Superfund sites.
There is no apparant basis for requiring cleanup to a more stringent standard
than health-based drinking water standards. Accordingly, a technical
im racticabilit waiver of the North Carolina roundwater standard would be
warranted since compliance with this state standard is not technically
practicable at this Site from an engineering perspective. Health-based MGLs
and State drinking water standards should be considered as primary AJRs
for groundwater.
The development of remedial objectives must also
consider the existing and potential use of the aquifer. Groundwater off Site is
considered a Class II!!. Aquifer since it is sometimes used as a private driJking
water source (USEPA, 1988, Guidance on Remedial Actions for ContamiAated
Groundwater on Superfund Sites).
17
• •
The restoration of on-Site groundwater quality for use as a
potential source of drinking water is unlikely due to technical
impracticability. For example, the maximum concentration of vinyl chloride
on Site is 68,000 µg/L, whereas the State Groundwater Standard is 0.015 µJ/L.
This would require 99.99997% removal of vinyl chloride from groundwa/er
which may not be achievable using current aquifer restoration technologiles.
Similarly, benzene, 2-butanone, carbon tetrachloride, chloroform,
1,2-dichloroethane and methylene chloride require greater than 99.9%
removal on-Site to meet the State Groundwater Standard. Given that Site
groundwater is not a water supply and there is readily available access to 1
municipal watermain, restrictions for on Site groundwater use are
appropriate under the circumstances.
Groundwater and drinking water regulations allow for
the establishment of variances, waivers and the establishment of a point lof
com liance. In the case of the adco-Hu hes Site the oint of com liancJ
should be the downgradient property limit. Hence, State and Federal
drinking water standards would be met at the Site boundary while on-Site
groundwater concentrations would not be required to meet State or Fede~al
Standards. Appropriate groundwater use restrictions should be establish~d
for on-Site groundwater.
Given the above discussion, the remedial objectives for
I for groundwater are based on health-based federal MCLs. These groundwater
I
remedial objectives are applied to off-Site groundwater only with the point of
compliance being the Site boundary.

Subject: Recommended Activities and Sampling Locations for the
Limited Field Investigation at the Jadco-Hughes Site
Work Assignment No.: 68-4LG8
Dear Mr. Orban and Ms. Dao:
This letter expands upon the information contained in our July 29, 1985
letter regarding the cost of a limited field investigation at the I
Jadco-Hughes site. We have considered the activities suggested in the
July 29 letter in greater detail and have developed specific I
recommendations for field activities which we feel will help define and
limit the scope of work required for a Remedial Investigation/Feasibility
Study (RI/FS).
Completion of the geophysical investigations is strongly recommended .. An
EM survey originally scheduled for completion by NUS in March of 1983 was
I not completed because of inclement weather. Consequently, a report of
buried drums in the area along the western site fence has not been
confirmed. The presence of buried drums may affect the placement of
future monitor wells. Therefore, location of any buried drums at this
stage in the investigation will guide the selection of monitor well
locations for the RI/FS. Because there is little existing data
describing the stratigraphy in the site vicinity, resistivity soundings
are recommended.
The existing surface water and sediment sampling database contains
several discrepancies, many of which may be attributed to the sampling
location selected. For example, upstream sediment sample JmHo2s-tUF

CfB-t8he:osne
Tributary B contains several organic compounds. However,

are either polynuclear aromatic hydrocarbon (PAH's) compounds commonly
associated with asphalt that may be present in runoff from Cason Street
or naturally occurring fatty acids that may be associated with vegetation
in the area. I
In addition, the locations previously selected do not allow isolation of
a particular source of contaminant inflow. Sample JH2-UFCA-5 was taken
downstream of Cason Street on Tributary A and sample JH2-UFC-9 was t.iken
at the confluence of Tributaries A and B. Conclusions cannot be made
regarding the potential flow of contaminants from the north face of the
site into Tributary A because sample JH2-UFCA-5 may be affected by runoff
from Cason Street, and sample JH2-UFC-9 also contains inflow from
Tributary B.
Finally, previous investigations were not designed to define the extent
of contamination. Sediment sample JH2-UFC-9 contains several
contaminants. However, no samples were collected from additional
downstream points to determine the extent of contaminated sediments in
Fi tes Creek.
Surface water and sediment sampling at the 12 locations listed in Tab
1
le 1
and shown on Figures 1 and 2 is highly recommended. These samples should
all be analyzed for the full priority pollutant scan. The objectives of
sampling at these locations include:
• ·Isolation of potential routes of contaminant migration.
• Confirmation of suspected contaminant migration into the culvert
passing through the site. I
• Investigation of the extent of downstream contamination of Fites
Creek.
Proposed Sample Collection Stations
Sample JH3-UFCA-l will be collected from a point further west to
determine upstream conditions in Tributary A away from any runoff from
Cason Street. Samples JH3-UFCA-2 and JH3-DFCA-3 wi 11 be collected to\
isolate any contaminant migration from the north face of the site.
Sample JH3-UFCB-4 represents upstream conditions in Tributary B away from
any runoff from Cason Street. Samples JH3-·UFCB-5 and JH3-DFCB-6 will [be
collected to isolate any contaminant migration into the buried culvert
passing under the site. Comparison of the August 1983 results of [
laboratory analyses for samples JH2-UFCB-8 and JH2-M indicates that the
culvert passing under the site is not securely sealed, and existing
onsite contaminants are migrating into this culvert.

Samples JHJ-DFCB-6, JHJ-DFCB-7, JHJ-DFCB-8, and JHJ-DFCB-9 will be
collected to isolate contaminant migration from the east face of the
northern portion of the site. Sample JHJ-DFCAB-10 will be collected on
the upstream side of SR 2036 about 800 feet downstream of the site in an
attempt to define the limit of downstream sediment contamination. \
Samples JHJ-S-1 and JHJ-DS-2 will be collected to isolate any contaminant
migration into the stream flowing from the spring to Tributary B.
We feel that this proposed field investigation will help limit the
sampling required during the RI/FS through the isolation of sources of
contaminant migration. In addition, the extent of contaminant migration
in Fites Creek will be more clearly defined.
Table 2 contains a revised cost estimate for the limited field
investigation. Notable changes include an increase in the labor cha~ges
for surface water and sediment sampling. Addition of 2 more sampling
locations as well as the collection of both surface water and sediment
samples will require an additional day in the field. A contingency ~or
inclement weather halting field activities has been added. Labor cha,rges
for summary and evaluation of the data are included. This activity does
not include a review of the information collected regarding private wells
in the site vicinity. We propose that completion of this task be
deferred until the work plan preparation phase.
Equipment charges have been increased to reflect samp 1 e shipping charges
that will be incurred if use of a contract laboratory is required.· W,e
are currently investigating the availability of lab slots for the week of
August 25, 1985, and will advise you of our findings. Charges for I
lodging and meals have been increased to accomodate an extra day in the
field. I
The estimated total cost for the limited field investigation is $14,500.
We currently have $10,000 available in the Forward Planning Study budget.
It is our feeling that while adjustments can be made to accomplish the
recommended field activities at a cost of $10,000, this does not allo~
any flexibility to compensate for inclement weather or any other I
unforeseen delays. Furthermore, a thorough summary and evaluation of the
data obtained would not be possible. For these reasons we recommend ~n
increase of $5000 and 100 LOE hours in the interim authorization for this
work assignment.

Dear Ms. Benoy:
I Re: Jadco Hughes Superfund Site
I Revised Feasibility Study (FS) Report
I This letter has been written to submit supplemental comments on the FS on behalf
?f the Jadco-Hughes Steering Committee. EPA Comment No. 4 states 'The FS must
identify the contaminant levels acceptable to the POTW. Without these
levels/ standards identified by the POTW, this discharge alternative will not be
tonsidered."
I ,The FS has identified the following three remedial technologies for treated
groundwater disposal: discharge to surface water; discharge to POTW; and on-site
aischarge via infiltration. The on-site discharge via infiltration technology is not
kcceptable to the State of North Carolina. The remaining groundwater discharge
klternatives are protective of human health and the environment and will comply
rith all applicable ARARs.
jfhe requirement to identify contaminant levels acceptable to the POTW is not
supported by the National Contingency Plan, 40 CFR Part 300 et seq. and is
premature at this stage. The level and degree of treatment of the extracted
'groundwater will depend on the ultimate discharge point of the water and the level
'of contaminants in the extracted groundwater. The USEPA should defer the
:decision on the groundwater disposal until the most cost effective combination for
l
the point of discharge and degree of treatment can be determined in the Remedial
Design stage. The Record of Decision (ROD) should reflect this approach. The
IUSEP A has used this approach in other RODs. A copy of the Caro lawn ROD is
enclosed as an example.

Fort _.I.awn·, Chester County, South carolina
STATEMENT OF BASIS AND PURPOSE
Thie decision document represents the selected remedial action for the
Carolawn site in Fort Lawn, south carolina chosen in accordance with CERCLA,
I as amended by SARA and, to the extent practicable, the National Contingency
Plan. Thie decision is based upon the administrative record for the Carolawn
Site.
The State of South Carolina has concu=ed on the selected Remedy.
ASSESSMENT OF THE SITE
Actual or threatened releases of hazardous substances fr0111 the Carolawn site,
if not addressed by implementing the response action selected in this Record
I of Decision, may present an imminent and substantial endangerment to public
health, welfare, or the environment.
DESCRIPTION OF THE SEIJ!!CTED REMEDY
MIGRATION CONTROL (Remediation of contaminated Groundwater)
Installation of a groundwater interception and extraction system at the
I site. The level and degree of treatment of the extracted groundwater will
I depend on l) the ultimate discharge point of this water and 2) the level of
contaminants in the extracted groundwater. Three wate , discharge I
alternatives for the treated groundwater are l) the lc:al sewer ~stem,
(i.e., Publicly OWned Treatment works), 2) Fishing creek via a National
I Pollution Discharge Blimination System permit or, 3) on-site irrigation. A
fourth discharge possibility is groundwater injection. The range 1\of
treatment for the extracted groundwater includes air stripping,
biodegradation, filtration through activated carbon filter and metal
I removal. The moat cost effective combination for the point of discharge
I and the degree of treatment will be datermined in the Remedial Design
stage. The discharged water will meet all ARAR•a. Concurrence on\ the
final design will be requested from the State of South Carolina. Comments
will also be solicited from the public on the final design.
Review the existing groundwater monitoring system to insure proper
monitoring of groundwater. If deemed necessary, additional monitor wells
will be installed to mitigate any deficiencies in the existing gro~ndwatsr
monitoring system.
Appropriate institutional controls (deed restrictions) will be
implemented.
Open the condemnation of the adjacent contaminated private, potable wells
by the county of Chester, these -110 will be plugged in accordance· to
South carolina Department of Health and Environmental control regulations.
SOURCE CONTROL (Remediation of contaminated Soils)
Due to the effectiveness of the removal actions, no source of contamination
I remains within the fenced area of the site. However, additional field work
I is required in the disposal area north of the fenced area. This field work
I will consist of the installation of confirmatory soil borings to verify the
' presence or absence of contamination in this area. If no contamination is
I found, there will no source control remediation required at the C&rolawn
site, however, if contaminated soil is found, a second Record of Da.!:ision
will be necessary to address this source of contamination.
GENERAL SITE CLEANUP ACTIVITIES
The two inactive incinerators will be inspected and any remaining residue
will be sampled and analyzed. Also, wipe samples will be collectedland
analyzed. The results of the analyses will determine the method of
disposition for the incinerators. The two remaining drums will also be
sampled and analyzed to determine bow they will be disposed. In addition,
I site cleanup will include closing of the equipment decontamination area
used during Phase I RI activities.
DECLARATION
The selected remedy is protective of human health and tha environment,
' complies with Federal and State requirements that are legally applicable or
I relevant and appropriate to the remedial. action, and is cost-effective. Thie
I remedy util.izee permanent solutions and al.ternative treatment technologies to
the maximum extent practicable and satisfies the statutory preferancelfor
remedies that employ treatment that reduces toxicity, mobility, or volume ae
I a principal element. Since this remedy may result in hazardous substances
' remaining on-site above health-based levels, the five-year review will apply
to this action.

Groundwater clean-up ARARs for the site are incorrect. The
contaminated aquifer is a Class IIB aquifer; therefore clean-up
must be to MCL, North Carolina drinking water standards, MCLGs,
or proposed MCLs. Where promulgated or proposed standards do
not exist other criteria based upon the protection of human
health must be used as groundwater protection standards. Be
advised that where new MCLs have been proposed they will take
precedence over the existing MCLs since the site must be
remediated to standards that are current when remediation is
completed.
Delete all of Section 2.0 as presented. The tables in this
section may be incorporated into text of report. See comment
2, and comment 21.
The St~ering Committee has presented Alternative 9 as their top
prefSrence for the recommended remedy. Alternative 9 consists
of Soil vapor extraction, soil flushing, groundwater
extraction, treatment and discharge (to POTW). This
Alternative must be expanded to include NPDES discharge to
local surface water, and onsite discharge via infiltration as
well as discharge to POTW. The groundwater discharge criteria
must meet:
MCLs, PMCLs and Health based levels for onsite discharge via
infiltration,
NPDES permit discharge requirements,
contaminant levels acceptable to POTW.
All the above criteria, with the specific levels of
contaminants detailed,· must be identified in the revised FS
report for each of these three discharge alternatives. The FS
must identify the contaminant levels acceptable to the POTW.
Without these levels/standards identified by the POTW, this
discharge alternative will not be considered.
The approach for using groundwater cleanup standards in the
application of soil remediation is unacceptable. The FS has
made no attempt to properly determine site specific action
levels. Therefore, the only technically defensible soil
cleanup goals in the absence of site specific evaluations and
action levels are background concentrations.

2.1 REMEDIAL ACTION OBJECTIVES
2.2 GENERAL RESPONSE ACTIONS
2.3 APPLICABLE OR RELEVANT AND APPROPRIATE REQUIREMENTS
2.3.1 Applicable requirements
Applicable requirements are specific to the conditions
present on the site for which all of the jur~sdictional
prerequisites of the law or requirement are satisfied.
Applicable requirements are cleanup standards, standards of
control, and other substantive environmental protection
requirements, criteria, or limitations promulgated under
Federal and State law that specifically address a hazardous
substance, pollutant, contaminant, remedial action, location,
or other circumstance at a CERCLA site.
•
• Jadco-Hughes Feasibility Study Report
Agency Comments
Page 5
2.3.2 Relevant and Appropriate Requirements
Relevant and appropriate requirements are cleanup standards,
standards of control, and other substantive environmental
protection requirements, criteria, or limitations promulgated
under Federal and State law that, while not "applicable" to a
hazardous substance, pollutant, contaminant, remedial action,
location, or other circumstances at a CERCLA site, nonetheless
address problems or situations sufficiently similar to those
encountered at the CERCLA site such that their use is well
suited to the particular site.
2.3.3 Guidelines to be Considered
Non-promulgated advisories or guidance issued by federal or
state government when determining cleanup levels. Such
criteria are known as "to be con~idered" guidelines. Such
guidelines would be applied when no promulgated ARARs exist to
address a particular situation adequately.
2.3.4 Types of ARARs
Guidance for the determination of ARARs is presented in the
USEPA guidance document entitled "Interim Guidance on
Compliance with Applicable or Relevant and Appropriate
Requirements", dated August 27, 1987. The above-referenced
guidance document identifies several types of ARARs which may
have to be considered during .the RI/FS process. These include:
1) Chemical Specific ARARs:
These requirements consider specific concentration
limits of hazardous constituents detected in the
various environmental media. For this group of
requirements the more stringent ARARs would be
considered for determination of an acceptable cleanup
level of the specific hazardous constituent. Examples
of ARARs which fall under this category include:
Federal Maximum Contaminant Levels (NCLs), Federal
Ambient Water Quality Criteria (AWQCs), North Carolina
Primary Drinking Water Standards, and North Carolina
Surface Water Qualtiy Criteria.
•
• •
Jadco-Hughes Feasibility Study Report
Agency Comments
Page 6
2) Action Specific ARARs:
This group of requirements considers ARARs which are
action specific for the management of hazardous
substances such as: Resource Conservation and Recovery
Act (RCRA) regulations for hazardous waste management
facility clsures; RCRA incineration standards; Clean
Water Act pretreatment standards for discharges to
Publicly owned Treatment Works (POTWs). In most cases,
these ARARs are considered at the time of the remedial
alternative evaluation during the FS.
3) Location specific ARARs:
These requiremnts are generally considered in the FS
where restrictions due to the site characteristics or
the surrounding environment exist. Examples include:
Federal and State siting laws for hazardous waste
facilities, sites on National Register of Historical
Places.
The ianguage used in section 1.4 of the FS should be included
in Section 2.1 and 2.2 as provided above. All other language
provided above will be used as provided above.
22) Table 2.1
2. RCRA is an applicable location specific ARAR. Change
table to include as an ARAR.
3. RCRA Land Disposal Restrictions (LDRs) are applicable
for location specific ARARs. Change table to include.
4. Federal Manifest for Transposrt of Hazardous Waste is
applicable for location specific ARARs. PRPs have
proposed to transport PCB contaminated soils off site.
Change table to include.
9. Clean Air Act is applicable. Review of the report
indicates that soil venting is being considered which
dictates that the Clean Air Act is applicable. Include

10. National Environmental Policy Act is relevant. A copy
of the reference sited in the statement "CERCLA FS
guidance states that CERCLA actions are exempt" may be
submitted for consideration. This appears to be taken
out of context.

which may be an ARAR for the site.
23) Table 3.1
Add ~~~am stripping and incorporate as appropriate.
24) Specifically, evaluation criteria for groundwater remediation
must be evaluated as follows:
First criteria, (threshold criteria), to be used in remedy
selection are:
Overall protection of human health and the
environment: Will the remedy achieve clean-up levels?
Are all exposure pathways controlled; e.g., discharge
points, points of use?
Compliance with ARARs: Will the remedy attain MCLs or
state standards in potentially drinkable groundwater or
justify a technical impracticability waiver? Are ARARs
met for the treated groundwater and any treatment
residuals that are generated?
Second criteria, (balancing criteria), to be used in remedy
selection are:
Long term effectiveness and permanence: Remedies that
achieve the cleanup levels will be comparable with
respect to this criteria. For remedies that will not
restore groundwater, how reliable are the-engineering
or institutional controls used to prevent exposure?
Reduction of mobility, toxicity, and volume: What
reductions are achieved through treatment in any phase
of the remediation process? This includes initial
treatment of groundwater and
•
• Jadco-Hughes Feasibility Study Report
Agency Comments
Page 8
•
subsequent treatment of resulting residuals. Special note should
be given to remedies that transfer contaminants from groundwater
to air without treatment of the air releases, especially if risk
through the air pathway exceeds 10 -G.
Short-term effectiveness: What is the restoration time frame?
What cross-media impacts occur as a result of groundwater
treatment or construcion of a containment facility? How much
farther will the plume spread before the remedy is completed?
Implementability: What permitting requirements must be met for
discharge of treated groundwater? Are there access problems with
installation of the remedy--e.g., extraction wells and slurry
walls--in terms of resources required? Are there capacity
limitations on POTWs receiving discharge waters? What
uncertainties exist with the treatment process considered?
Cost
Final criteria, (Modifying criteria):
State acceptance
Community acceptance
If the alternatives will achieve the same long term goals, the
primary balanceing criteria will be implementability, cost and short
term effectiveness.
Elaboration is provided above for groundwater, but the above criteria
are commonly known as the 9-Point Criteria which must be the
substantiated criteria used in remedy selection for all remedial
actions taken at Superfund sites.

Thank you for allowing us the opportunity to comment on the proposed
Draft Feasibility Study for the Jadco-Hughes Superfund site located in
Belmont, Gaston County, North Carolina and the proposed Draft Remedial
Investigation Study Report for National Starch Chemical Superfund site located
in Salisbury, Rowan County, North Carolina.
My staff has reviewed the draft documents and has no specific comments
about the reports. However, I would like to express once again our concerns
about EPA's review procedures which does not provide this Section with
sufficient information for review regarding a particular project to assure
that all state or local air pollution standards are being protected. Although
an air discharge permit may not be required for a Superfund project, this
Section would appreciate an opportunity to review and comment on a project
prior to any remedial operations to determine compliance with any applicable
ambient standards including our toxic standards. Consequently, without an
opportunity to review all aspects of a Superf_und project, this Section can not
make such a finding. Any support from the Division of Solid Waste Management
in obtaining more complete information (not one report or investigation at a
time) from the EPA for our review and comment regarding a Superfund project
would be greatly appreciated.

Section 3.1 indicates that the metals analyses are in ppm;
however Table 3-2 indicates that the metals were in ppb. Table

Based on Water Section's review of the subject material, the
following comments are offered:
Surface water sampling results indicate that the surrounding
tributaries are not impacted by groundwater contamination. The
northeast tributary showed minor 1,2 dichloroethane
contamination, source unknown, but possible surface water runoff
from the plant. National Starch has constructed a dike to
contain the runoff and is conducting a study to determine how to
pump or redirect the runoff to the wastewater lagoons.
Further evaluation of surface waters and remedial action to
prevent contamination appears to be necessary, as relates to
runoff.

Jadco-Hughes NPL Site
Belmont, Gaston County, North Carolina
Dear Ms. Benoy:
William L. Meyer
Director
The North Carolina Super fund Section is pleased, to offer
· these comments on the Jadco-Hughes Site Feasibility Study (FS)
prepared by Conestoga-Rovers and Associates for the Jadco-Hughes
Steering Committee. We appreciate your working with us to
provide these comments on a reasonable time frame. Please note
that we have forwarded the FS to the North Carolina Division of
Environmental Management for their review also. Their comments
will be forthcoming as soon as possible.
The North Carolina Superfund Section offers the following
specific comments:
1. Table ES-2, Executive Summary. For clarity and consistency
with Alternative 1, the descriptions of alternatives-9 and
11 at the top of each column should not have bullets besides
them. It is also noted in this table that both Alternatives
9 and 11 "reduce future potential risks of human contact.
with contaminated soil 11 • HOl•lever, it should be noted in
this table that the incineration technique (Alternative 11)
would be more effective at reducing contaminant levels, and
would therefore reduce potential risks to a greater degree
than Alternative 9. On page 3 of this table in the third
paragraph of the far right hand column ''tthree'' should be
"three".
These comments also pertain to Table 6.1 on page 120.
2. Page 4 and 5. As we commented earlier on the Draft Remedial
Investigation the NC Superfund Section suggests the removal
of all references to contaminant mass estimates. There is
no statistically sound basis for these estimates, and we see
there inclusion as potentially misleading. Please refer to
our 19 January 1990 RI comments for a more detailed
rationale for this.

3. Figures 1.8 and 1.9. The landfill area is not labeled
as such.
4. Page 6, Section 1.2. The NC Superfund Section strongly
supports the interim remedial measures that are
outlined in this section. We would further ask the
question, is there a schedule for these actions?
Also, this section states that the cleanup will be
conducted which satifies the U.S. EPS PCB Spill Cleanup
Policy (40 CFR 761). In addition to the 10 ppm cleanup
level it establishes, this policy states that the
excavated soil (minimum of 10 inches) will be replaced
with clean soil and then vegetative cover will be
restored (40 CFR 761 10694). As descrbed in the·Spill
Cleanup Policy, the report should state that clean soil·
will be used as · backfill an then vegetative cover
restored.

Table 2.1. In the fourth column, row 5 for the Toxic
:substances Control Act there are typographical errors.
For State ARAR's the Table does not mention North
Carolina Ground Water Standards as set forth in Section
.0202 of Title 15 of the North Carolina Administrative
Code (see Comment 6 below).
Page 15, Section 2. 1. 3. The ARAR' s for ground water
should consider North Carolina Ground Water Quality
Standards in addition to the North Carolina Drinking
Water Act (NCDWA) . The NCDWA mirrors the levels set
forth by Federal MCL's. However, the report does not
consider the ground water standards set forth in
Section .0202 of Title 15 of the North Carolina
Administrative Code, which in some cases are more
stringent than the MCL' s. A copy of this code is
attached. Enforceable standards exist for many of the
contaminants that are present in the ground water on
site. In fact, in many instances the site is in
violation of these standards .. [ Please note that. further
comments on this FS are forthcoming from the NC
Division of Environmental Management which is the
agency charged with upholding the ground water
standards. They may have additional comment on this
subject.]
7. Page 16, paragraph 1. The last sentence states that
MCL' s and State drinking water standards should be
considered as the primary ARAR's for ground water. We
feel that the State ground water quality standards
described above should be the ARAR's in cases where the
ground water standards are more stringent than the
drinking water standards. [ Please note that further
comments on this FS are forthcoming from the NC
Division of Environmental Management which is the
agency charged with upholding the ground water
standards. They may have additional comment on this
subject.]

FS Comments, page 3
Also, what will be the ARAR or remedial goal for
the numerous compounds for which there are no MCL' s
drinking water standards, or ground water standards?
Will Proposed MCL's be considered if there are no
MCL's?
Also, this section is too general. After reading
the section it is unclear as to what the cleanup levels
will be. It states that MCL' s "should" .be considered
as the primary ARAR's not "shall". No specific cleanup
criteria are presented. The Superfund Section needs to
see specific cleanup criteria before supporting the
Feasibility Study.
8. Page 17, paragraph 4. The·report states that the·MCL's
for some contaminants wi11· be below background levels
and in these cases.the background levels should then be
the remedial objective. Cadmium is given as one
example, but more specifics are needed. What are the
others·, what are the levels they propose as
"background", and how do the "background" · levels
compare to the MCL's. This again goes back to
Comment 6 and the fact that specific remedial
objectives are not presented fan each contaminant
9. Page 17, paragraph 1. The report states that
"restrictions on Site [sic) groundwater use are not
appropriate under the circumstances." The North
Carolina Superfund Section believes that restrictions
should be considered if appropriate remedial objectives
are not ultimately met by the remedial actions taken.
This should be stated here.
10. Page 18 and 19, Section 2.3. The report proposes that
if no ground water contamination is observed after a
period of soil remediation (soil vapor extraction (SVE)
followed by soil flushing in the selected alternative)
the soils must be "clean". We do not support. this
theory. We strongly recommend subsurface sampling be
conducted during and after the SVE and soil fiushing to
confirm the reduction in soil contaminant levels and to
be sure that the soils will no longer be a source of
ground water contamination.
11. Page 19, Section 2.4. This section describes the PCB
cleanup criteria taken from the U.S. EPA' s PCB Spill
Cleanup Policy (40 CFR 761) as 10 mg/Kg. Again, as
stated in Comment 4 above, this policy decribes clean
backfill and cover replacement which should .be
described in this section.
12. Table 2. 4. On page 2 of . this table the contaminant
category in the first column is given as "Pesticides/
PCB's''. Only one row of data is presented. Is it for
pesticides or PCB's? What specific pesticides or
PCB's?

13. Page 22, Section 3. 1. 3. It is noted that the
construction of a cap requires excavating soils in the
former operations areas. This would be cause for voe
air emissions. This is not mentioned in Table ES-2 in
the executive summary for all of the alternatives that
propose a cap. However, air emissions of voe' s are
mentioned for those alternatives that propose
excavating soils for disposal. It is noted that there
is apparently no proposal for remediating residual soil
contamination in the decant pit areas. This issue is
dealt with in more detail in Comment 29.
14. Page 27,· paragraph 1. The report states that inorganic
contaminants are.not removed·by incineration and remain
in the decontaminated soil. This is not entirely true
in the case of arsenic which does appear to be present
on site. Arsenic can volatilize in an incinerator.
15. Page 31, section 3. 1. 7. 4. This section describes "soil
washing" as a remedial technology. • It states that
"soil washing would be conducted in-situ ... " This is
customarily referred to as "soil flushing" whereas soil
washing is soil removal followed by a washing unit
operation. In fact, elsewhere in the report, the term
"soil flushing" is used (it is part of the selected
alternative). Therefore, it appears that this section
should be entitled "Soil Flushing" consistent with the
rest of the report.
If this is the case, then a new section describing
and screening soil washing technology should be added.
16. Page 3 2, paragraph 2. The report mentions that soil
washing [flushing] is often conducted with surfactants
to help remove organics and nutrients/oxygen to promote
in situ biodegradation. These principles were not
explored or described anywhere in the report. Is it
proposed to use surfactants? Is it possible that they
would help remove certain contaminants that might
otherwise be difficult to remediate? Why not add
nutrients and oxygen to · enhance bidegradation at the
same time? If an infiltration system is set up to
flush the soil it would be very little additional·
expense to attempt to enhance in-situ biodegradation.
Given the type of contaminants, this site seems well
suited to in-situ biodegradation for ground water
remediation and it is given only a cursory discussion.
Is it possible to include in situ biodegradation in the
analysis of the alternatives?
1 7. Page 3 4, Section 3. 1. 7. 6. The report presents Table
3.5, a treatability evaluation for soil venting. What
is the basis for the data presented in the Table?
Treatment costs are presented as "$50/ton". The
question here is per ton of what?
Jadco-Hugh.Site
FS Comments, page 5
The limitations of this technique as it pertains
to this site are not presented. What specific
contaminants can and cannot be removed by this
technique. For example, it is not expected to remove
most PAH compounds. Is this a problem for this site?
There are PAH compounds present in the soils. If they
are not removed by venting is it a problem or can
another technology be employed to remove them. It is
this type of analysis that is lacking throughout all of
Section 3.
18. Page 40, paragraph 2. The report· describes the
rainfall total for "Greensboro, South Carolina"·. Is
this correct? Should this be North Carolina? If so, I
suggest using meteorological data for Charlotte or
Gastonia instead.~ These cities are much closer to the
site.
19. Page 45, section 3. 2. 5. 4. It is suggested that the
last sentence be changed to read, "The subsurface tile
are applicable only to the extraction of shallow
groundwater, whereas extraction wells are applicable to
the extraction of shallow ·groundwater, contaminant
pockets, and deep groundwater."
20. Page 45-48, Section 3.2.6.1. The ground water remedial
technologies. discussed do not include in-situ
biodegradation. This technology appears to hold
promise at this site. As stated in the report on page
33, most of the principal site contaminants could be
successfully bioremediated. Considering the fact that
soil flushing is the selected technology for soils
remediation, it would be logical to also attempt
in-situ biodegradation.
Also, on page 46 it states that one of the reasons
that on-site fixed film biodegradation was screened out
is the lack of organic nutrients in the· ground water.
They can be added easily.
On page 48,. ultraviolet oxidation is described.
It should be noted that this will require pretreatment
for iron removal as stated in ~able 3.6.
21. Page 51, paragraph 4. We suggest that the word "even"
be deleted.
22. Page 52, Section 3.2.9. The title of this section may
be more accurately described as "Culvert Lining/
Replacement". Can the slip lining technique be
described a little more?
23. Page 53 , Table 3.6. For soil treatment technologies,
the comments are not clear for soil washing. The
comments concerning oxygen and nutrients appear to be
more related to in-situ bioremediation. Also, Soil
Flushing is not presented in this table.
Jadco-Hugh.Site
FS Comments, page 6 •
For ground water treatments, in-situ
bioremediation has not been evaluated (see Comment 19,
above). Also, reverse osmosis . is described as
applicable to the treatment of inorganic wastes which
therefore make it inapplicable to the site. This is
incorrect as reverse osmosis can be used to remove many
organic contaminants as well.
24. Page 57 and 58. Concerning the extraction of ground
water, the report states that the extraction wells will
extract ground water at the rate of 1 gallon per minute
(GPM). How was this rate selected? What was the
rationale? How would this rate affect flow patterns
and prevent future migration? , Without the analysis
present in the report we can only say that this rate
seems entirely to"o low. There are hot spots where
there are high contaminant levels that ar8 acting
almost as a point source. To prevent further problems,
it would seem logical to remove these hot spots
quickly. The total system flow rate of 14 GPM also
seems low.
What is the contaminant depth as determined by the
'RI. Is it definite that the subsurface drains will cut
off the contamination at the property line or is there
deep contamination that may pass through. A thorough
analysis of the flow patterns and contaminant cut off
to support the basic design· of the extraction system
should be included here. This same comment also
applies to Section 4.4.9 on pages 89 and 90.
25. Page 58, Table 4.2. The wells should be sampled more
frequently, particularly those at or just beyond the
property boundary. All of the wells should be sampled
quarterly for years and then annually thereafter. For
those wells at or just beyond the property line (MW-14,
MW-12, MW-5, and the subsurface drain) they should be
sampled quarterly for 5 years and annually thereafter. ,
· 2 6. · · Page 59, paragraph 1. There should be a statement at
the end of this paragraph that new monitoring wells
would be installed if the flow patterns change enough
to warrant monitoring in new locations.
27. Page 62, paragraph 3. .This paragraph mentions a
manhole sump for the collection of annular space ground
water. Is it possible to show this sump on Figures 4.2
and 4.3?
28. Page 73, paragraph 1. The report mentions an ozone
pretreatment system to remove iron. Is it possible ·to
show this system of Figure 4. 7? Why would an ozone
pretreater be required? Could the pretreatment -be
simple water softening or pH adjustment?
Jadco-Hugh.Site
FS Comments, page 7 •
29. Page 74-77, Section 4.4.5. The proposed SVE and soil
flushing would not remediate the two decant pits areas.
Can a rationale be presented for not remediating these
areas? Also, many of the site contaminants will not be
remediated by the SVE/soil flushing. Can a discussion
be included that covers these compounds and whether or
not leaving them as a residual will be a problem. This
discussion may best be suited for Section 4.4.5.1.
This comment is also pertinent to Section 5.4 on page
106.
31. Page 86, paragraph 2. voe emisiions are~ concern ..
Therefore, this and other alternatives that require
excavation should include{ air moni taring, for. voe' s and
, contaminated · pa'rticulate·;, in · the analysis. 'of . each
alternative. It . is agreed · that .. a'ir emissions are a
concern, but the public health can'be' protected with an
air monitoring program during operations. W~ do not
see this .. as an overriding reason · to eliminate
alternatives with excavation.
32. Page 105, paragraph 1. The report states, "At present,
groundwater ARAR' s are met." This,, is not correct as
the site currently violates State ground water
standards. As described in the NC Administrative Code
Title 15, subchapter 2L, Section .0202, there are
ground water standards for the state regardless of
aquifer use.
3 3. Appendix B. Most of the tables presented in this
section are unreadable due to the poor photocopy
quality. Also, it would be of great benefit to the
reader to present summary tables of the VOC's and
BNA's.
34. Appendix C. In-situ biodegradation is not evaluated·
as a remedial technology.

(a) N.C. General Statute 143-214.1 directs that the Commission devc!op and adopt after proper study
a series of classifications and standards which will be appropriate for the purpose of classifying each of
the waters of the state in such a way as to promote tht.: policy and purposes of the act. . Pursuarit tO
this statute, the mies in this Subchapter establish a series of classifications and water quality standards
applicable to the groundwaters of the state ..
(b) These mies arc applicable to all activities or actions, intentional or accidental, which contribute
to the degradation of groundwater quality, regacdless of any permit issued by a governmental agency
authorizing such action or activity. except ·an innocent landowner who is a bona fide purchaser of
property which contains a source of groundwater contamination, who purchased such property without
knowledge or a reasonable basis for knowing ~hat groundWatcr contarnination had occurred, or a per-
. son whose int~rcst or ownership in the property is based or derived from a security interest in the
prope11y, shall not be considered a responsible party ..

. 0103 POLICY
(a) The rules established in this Subchaptcr arc intended to maintain and preserve the quality of the
groundwaters, prevent and abate pollution and contarnination of the waters of the state, protect public
health, and permit management of the groundwaters for their best usage by the citizens of North
Carolina. It is the policy of the commission that the best usage of the groundwaters of the state is as
a source of drinking water. These groundwaters generally arc a potable source of drinking water
without the necessity of treatment. It is the intt:nt of these Rules to protect the overall high quality
of North Carolina's groundwaters and to enhance and restore the quality of degraded groundwaters to
the level established by the standards ..
. (b) It is the intention of the Conunission to-protect all groundwaters to a level of quality at least as
high as that required under the standards established ITT Ruic .0202 of this Subchapter. In keeping with
the policy of the Commission to protect, maintain, and enhance water quality withITT the State of North
Carolina, the Conunission will not approve any disposal system subject to the provisions of G.S.
143-215.l which would result in:
(I). the significant degradation of grnundwaters of which the cxislITTg quality is better than the as-
signed standard, unless found to be economically and socially justifiable, or
(2) a violation of a ,vater quality standard beyond. the boundaries of the property on which the
source of pollution is located, or
(J) the impairment of existing groundwater uses or an adverse impact on the public health, safety
or welfare.
(c) Violations of groundwater quality standards resulting ffom groundwater withdrawals which arc
in compliance with water use permits issued pursuant to G.S. 143-215.15, shall not be subject to the
corrective action requirements of Rule .0106 of this Subchapter. ·
(d) No person shall ·conduct or cause to be conductCd, any activity which causes the concentration
of any substances to exceed. that specified in Rule .0202 of this Subchapter, except as authorized by the
rules of this Subehaptcr.

. 0104 RS DESIGNATION
(a) The Director is authorized to designate GA or GSA groundwaters as RS under any of the fol-
lowing circumstances: ·
(I) Where) as a result of man's activities, groundwaters col1.tain concentrations of substances in ex-
cess of the groundwater quality standards cstablishe11 under this Subchapter, and remedial action
to restore groundwater quality has been required, or
(2) Where a statutory vaiiance has been granted as provided ITT Rule .0114 of this Subchapter.
(b) The RS designation serves as a warning that groundwater so designated may not be suitable for
use as a drinking.water supply without treatment. The boundaries of areas designated RS may be ap-
proximated in the ·absence ;1f analytical data sufficient to define the extent of groundwaicr degradation.
The designation is tempor;cry ,u1d will be removed by 1hc Director upon a detennination that the
quality of the groundwater so designated has been restored to the level of the applicable standards or
when reclassified GC.

. 0106 CORRECTIVE ACTION
• T/5: 02L .0100
(a) The goal of actions taken to restore groundwater quality shall be restoration to the level of the
standards, or as close thereto as is econornica1ly and technologically feasible.
(b) Any person conducting or controlling an activity which rcsUlts in the discharge of a waste or
hazardous substance or oil to the groundwaters of the state, or in proximity thereto, shall take imme-
diate action to terminate and control the discharge, mitigate any hazards resulting from exposure to the
pollutants and notify the Department of the discharge.
(c) Any person conducting or controlling an activity which results in.an increase in the concentration
of a substance in excess of the groundwater standard:
( 1) ~s the result of activities, other than agricultural operations, not permitted by the state, shall.
assess the cause, significance and_ extent of the violation; subrnit a plan for cli.rninating the source
of contarnination and for restoration of groundwater quality; and iinplcmcnt the plan in ac-
cordance with a Special Order by Consent or a Special Order of the Commission.
(2) as a result of activities conducted under the authority of a permit issued by the state, shall, where
such concentrations arc detected: ·
(A) at or beyond a review boundary, demonstrate, through prcdictiv_e calculations or modeling,
that natural site conditions, facility design and operational controls will prevent a violation of
standards at the compliance boundary; or submit a plan for alteration of existing site coi1ditions,
facility design or operational controls that will prevent a violation at the compliance boundary,
and implement that plan upon its approval by the Director.
(13) at or beyond a compliance boundary, shall, assess the cause, significance and extent of the
violation of groundwater quality standards and submit the results of the investigation and a plan
for gr_oundwatcr quality restoration to the Director. Upon approval by the Director, the
permittec shall implement the plan in accordance with _a Special Order by Consent or a Special
Order of the Co,runission.
(d) In the evaluation of remedial action plans, the Director shall consider the extent of any violations,
the extent of any threat to human health or safety, the extent of damage to the environment, technology
available to accomplish rcstorati0n and the public and economic benefits to be derived from
grounqwater quality restoration.
(e) The Director may authorize the discontinuance of re.medial action to restore groundwater quality
to the level of the standard upon a demonstration by the responsible party to the Director that con-.
tiriuance would not result in significant reduction in the concentration of conta1ninants. In the con-
sideration of a request to discontinue fcmeclial actions, the Din~ctor shall consider the duration and
degree of success of remedial efforts, the feasibility of other treaiment techniques which could result in
furthef red.uction of contaminant levels, and the effect on groundwater users if containinants remain at
levels existing at the time of tennination of remedial action.
(f) Upon a determi.n~tion by the Director that continued remedial actions would result in no signif-
icant reduction in contaminant concentrations, the responsible party shall petition for a variance or a
reclassification of the impacted groundwaters.
-(g) . Where groundwater quality standards are exceeded as a result of the application of pesticides or
other agricultural chemicals, the Director shall request the Pesticide 13oard or the Dcpa.i1mcnt of Agra-
culture to assist the Division of Environmental iV1anagement in determining the cause of the violation.
lf the violation is detennined to have resulted from the use of pesticides, the Director shall request the
Pesticide 13oard to take appropriate regulatory action to control the use of the che,nical or chc,nicals
responsible for, or contributing to, such violations, or to discontinue their use.

(a) Best. Usage. Existing or potential source of water supply for potable mineral water and con-
version to fresh waters.
(b) Conditions Related to Best Usage. This class is intended for those groundwaters in which the
chloride concentrations due to natural c6nditions is in excess of 250 mg/1, but which otheiwise
may be considered suitable for use its potable water after treatment to reduce concentrations of

. 0202 WATER QUALITY STANDARDS
(a) The water quality standards for the groundwaters of the state are those specified in th.is Rule.
They are the maximum allowable concentrations resulting from any discharge of contaminants to the
land or waters of the state, which may be tolerated without creating a threat to human health or which
would otherwise render the groundwater unsuitable for i_ts intended best usage. Where groundwater
quality standards have been exceeded due to man's activities, restoration efforts shall be designed to
restore groundwater quality to the level of the standard or as closely thereto as is practicable.
(b) The maximum allowable concentrations for contaminants specified in Paragraphs (g) and (h) of
this Rule shall be as listed, except that: · .
(I) Where the maximum allowable concentration of a substance is less than the limit of
detectability, the substance shall not be permitted io detectable concentrations.
(2) Where two or more substances exist in combination, the Director shall consider the effects of
chemical interactions and may establish maximum concentrations at values less than those es-
tablished in accordance with Paragraphs (c) and (g) of this Rule. In the absence of information
to the contrary, the carcinogenic risks associated with carcinogens present shall be considered
additive and the toxic effects-associated with non-carcinogens present shall alsc be considered
additive. · ·
(3) Where naturally occurring substances exceed the established standard, the standard will be the
naturally occurring concentration as dctennined by the Director.
(c) Substances which are not naturally occurring and for which no standard is specified shall not be
permitted in detectable concentrations in Class GA ·or Class GSA groundwaters. Any person may
petition the Dlfector to establish an interim. maximum allowable concentration for an unspecified
substance, however, the burden of demonstrating those concentrations of the substance which corre-
spond to the levels described in Paragraph (d) of th.is Rule rests with the petitioner. The petitioner shall
submit al] toxicolog1cal and epidemiological data, study results, and calculations necessary to establish
NORTH CAROLINA ADM!NISTRA TIVE CODE 08/04/89 Page 8
EHNR -ENVJRONME,. MANAGEiHENT • T/5: 02L .0200
a standard in accordance with the procedure prescribed in Paragraph (d) of this Ruic. Within· three
months after the establishment of an interim maximum allowable concentration for a substance by the
Director, the Director shall initiate action to consider adoption of a standard for that substance.
(d) Maximum allowable concentrations for substances in Class GA and Class GSA waters arc es-
tablished as the lesser of:
(I) Systemic threshold concentration calculated as follows: [ Reference Dose (mg/kg/day) x 70 kg
(adult body weight) x Relative Source Contribution (.10 for inorganics;-.20 for organics)]/ [2
liters/day (avg. water consumption)];
(2) .Concentration which coffesponds to an incremental lifetime cancer risk of Ix Io·' ;
(3) Taste threshold limit value;
( 4) Odor threshold limit value;
(5) Maximum contaminant level; or
( 6) National secondary drinking water standard.
(e) The following references, in order of preference, shall be used in establishing concentrations of
substances which correspond to levels described tn Paragraph (d) of this Rule.
( I) Integrated Risk Information System (U.S. EPA).
(2) Health Advisories (U.S. EPA Office of Drinking Water).
(3) Other health risk assessment data published by U.S. EPA.
(4) Other appropriate, published health risk assessment data.
(f) Water quality standards specified in Paragraphs (g) ,me! (h) of this Rule and interim maximum
allowable concentrations established pursuant to Paragraph (c) of this Rule shall be reviewed on a
biennial basis. Appropriate modifications to established standards will be made in accordance with the
procedure prescribed in Paragraph (d) of this Rule where modifications are considered appropriate
based on data published subsequent to the previous review. ·
