Reasor Chemical Company Site, Castle Hayne, New Hanover County, NC
Dear Ms. Stynes:
Thank you for your comments dated July 30, 2003 regarding the Data Evaluation Report,
Revision I, and the Design Criteria Report, Revision 0, for the Reasor Chemical Company Site
located in Castle Hayne, New Hanover County, North Carolina. The purpose of this letter is to
address each of your comments.
Data Evaluation Report
1. Surface Water. During the Remedial Investigation (RI) and Ecological Risk
Assessment (ERA), surface water samples from Ponds 3 and 4 were not analyzed for inorganic
constituents. When it was realized that inorganic information was needed from the ponds, Ponds
3 and 4 did not contain surface water and therefore, samples could not be obtained. EPA does
have surface water inorganic results for Ponds 1 and 2. Although EPA does not have inorganic
data on surface water in ponds 3 and 4, we do have inorganic data from the sediments of all
ponds. The surface water inorganic contaminants of concern are copper, lead, iron and zinc.
Tables on the following page include concentrations of copper, iron, lead and zinc found
in sediment and surface water in ponds 1-4 during the May 1999 and.December 2001 sampling
events. During the May 1999 RI sampling event, of the four ponds, Pond 4. sediments had the
highest concentrations of these contaminants, except for iron, which was second highest in Pond
4. Pond 3 had the second highest concentration of copper. In the December 200 I ERA sampling
event, Pond 3 sediments had the highest concentration of copper, with Pond 4 following close! y
behind. Although there is not a perfect correlation between the surface water data and the
sediment data, if pond 1 had a copper sediment concentration of 100 mg/kg and surface water
concentration of 61 µg/L, it is a reasonable estimate to believe that water coming into contact
with sediments containing copper concentrations of 770 -920 mg/kg (Pond 4, Pond 3) would
most likely result in concentrations greater than the clean-up level of 7 µg/L. The "liquid tar"
from Pond 3 had concentrations exceeding cleancup levels.and it would be difficultto separate.
that from the surface water during removal. ·Therefore, in my professional judgment; I do not
believe that obtaining a sample of surface water from ponds 3 and 4 is necessary. I believe that it
is a safe assumption, based on the existing data, that if water is present in those ponds, it would

2. Groundwater Monitoring Schedule. Section 2.12.2.1 of th_e Record of Decision (ROD)
for the Site states, "Groundwater monitoring will take place annually, at a minimum, at the
existing monitor wells and former production wells and the data will be evaluated. All
groundwater samples will be analyzed for metals." During the Remedial Design (RD), I
scheduled semi-annual sampling because of the installation of the new monitoring well, and to
obtain more data-regarding thallium because of uncertainties in previous data. Because of the
installation of the new monitoring well, elevated concentrations found in it, and the "at a
minimum" language in the ROD, I have instructed Weston Solutions, Inc. (WESTON) to
continue with the planned September 2003 groundwater sampling and analysis event for the
Remedial Design. The groundwater sampling will occur on an annual basis during the Remedial
Action.
3. Amendment of ROD's Groundwater Monitoring Requirements. The groundwater
data at this Site has been puzzling throughout the RI and RD. The cleanup levels for
groundwater were set in the ROD for aluminum (16,000 µg/L) and thallium (2 µg/L) .. During ...
the RI, the cleanup level for aluminum was exceeded in temporary well TMW-8, in 1999, which
is the location of the newly installed MW-7. The cleanup level for thallium was exceeded in four
temporary wells sampled in 1999, and in production well PW-3 in 1999.
•• • Page 3
' .. '\,-. ...... ~··· .....
During the March 2003 RD groundwater sampling event, the only well with exceedances
of the ROD clean-up goals was MW-7S. During this sampling event, arsenic was detected above
the Safe Drinking Water Act Maximum Contaminant Level (MCL) of 10 µg/Lin well MW-2,
filtered (41µg/L}. However, it was not detected in the unfiltered sample from this well. The
MCLs for beryllium and lead were also exceeded in MW-7S. Groundwater samples could not be
obtained from PW-3 because of an obstruction. Page 5-7 of the Baseline Human Health Risk
Assessment for this Site stated that the carcinogenic risks in groundwater were largely due to
arsenic in on-site groundwater. · The concentration found during the March 2003 event in well
MW-2 (41 µg/L} was much higher than what was found during the RI (maximum detection of 3
µg/L}. Because of exceedances of MCL values for other constituents and knowing that a
decision.will.have to.be.made as.to,whether a groundwater remediation system is required,.l do ... _ .... ·
not agree with amending the ROD monitoring requirements at this time. This decision may be
re-evaluated'as.more data is received:
Design Criteria Report .
I. Revised Removal Volu·mes.· The revised volumes have been incorporated into the
preliminary construction cost estimate of the Remedial Design.
2. Construction of Access Roads. EPA would greatly appreciate improvement of the
access roads. If the access road improvements are made prior to finalization of the Remedial
Design, and they are sufficient to accommodate truck traffic during the Remedial Action, this
information will be incorporated into the design. If the improvements occur afterwards, but
before the remedial action, obviously this task, or a,portion thereof, of the scope of work will no
longer be required of the remediation contractor. Mr. Dannelly has EPA's response to the
proposed Interim Site Security Plan. ·
This concludes my response to your comments. Thank you for taking the time to review
documents related to this project and providing valuable comments. I look forward to meeting
with you again ori August 26, 2003 at 3 PM. If you have any questions, I can be reached at
(404) 562-8760 or via e-mail at URQUHART-FOSTER.SAMANTHA@EPA.GOV.

Work Assignment Number 147-RDRD-A424
Dear Ms. Offner:
I have reviewed the Data Evaluation Summary Report Revision l and the Design Criteria
Report Revision 0, dated July 2003, which Weston Solutions, Inc. prepared for the Reasor
Chemical Company Site Remedial Design. In addition, the North Carolina Department of
Environment and Natural Resources (NC DENR), U.S. Fish and Wildlife Services (US FWS),
and the property owners' contractor, CH2M Hill, also reviewed these reports and subrnitted
comments to me. Their comments are enclosed.
Most of my few comments were .also reflected by NC DENR and USFWS. Therefore, I
will not repeat them. On the attached page, I will provide my comments not mentioned by others
and provide discussion/direction regarding some of the comments submitted from NC DENR,
USFWS, and CH2M Hill. I will not list/discuss each of their comments, but only ones that I
either have a differing opinion or that need further evaluation. If you have any questions, please

Data Evaluation Summary Report. Revision 1
1. Now that the analytical data from the revised thallium analysis has been received, please
include it in the report. Since you mentioned yesterday that you still. have not received a
copy of the results, I am enclosing a copy, · · 0 •
2. NC DENR's comment #6 regarding well MW-2 turbidity was also one of my comments,
which we discussed yesterday. You said that on the original paper (not copies that we
received) the value for turbidity looks like 176 instead of 476. The value of 176 is also
more in line with·the other readings at-the well. Although there is a large numerical
difference between 176 and 476, both are above the recommend 10 NTU.
3. CH2M Hill's comment #2 discusses groundwater monitoring frequency. Section 2.12.2.1
of the Record of Decision·(ROD) for .the Site states, '-'Groundwater monitoring will take ,
place annually, at a minimum, at the existing monitor wells and former production wells
and the data will be evaluated. All groundwater samples will be 'analyzed for nietals."
During the Remedial Design, I scheduled semi-annual sampling because of the
installation of the new monitoring well, and to get more data regarding thallium because
of uncertainties in previous data. Because of the installation of the new monitoring well,
and elevated concentrations found in it, I would like to continue with the planned
September 2003 sampling and analysis event for the Remedial Design. However, for the
Remedial Action, sampling should occur on an annual basis. Please correct any
statements in the report which may indicate that sampling will be semi-annually instead
of annually during the Remedial Action.
4. CH2M Hill's comment #3 makes several valid points that I will take into further
consideration. However, at this time, please do not make any changes related to this
comment.
Design Criteria Report, Revision 0
1. In a meeting with the property owners on May 27, 2003, they offered the use of part of
their property as a borrow area, to obtain fill for backfilling excavated areas during the
remedial action. I will verify this with them. If this is a viable option, it could result in
cost savings.
2. Section 3.5 -Please revise the second sentence of this section. Semi-annual sampling is
scheduled for the Remedial Design, while annual sampling is intended for the Remedi_al
Action.
3. Whether or not the man-made ponds are considered wetlands appears to be an important
issue. Hopefully this will be resolved upon the U.S. Army Corps of Engineers visit to the
Site on August 27th. Because of U.S. Fish and Wildlife Services concern, I will also
invite them to meet me at the Site on that date to evaluate options for addressing this
issue. I will also discuss with the property owners the prospect of utilizing another area
of their property for habitat restoration, if needed.

Dear Ms. Urquhart-Foster:
Thank you for your July 17, 2003 correspondence requesting U.S. Fish and Wildlife Service
(Service) review of the Design Criteria Report (Revision 0) and the Data Evaluation Report
(Revision I) for the Reasor Chemical Company Site in Castle Hayne, New Hanover County, NC.
These comments are intended as technical assistance for the USEPA's assessments and planning
conducted pursuant to the Comprehensive Environmental Response, Compensation, and Liability
Act of 1980, as amended (42 U.S.C. 9601 et seq.); they do not represent any position that the
U.S. Department of the Interior may adopt concerning possible injury to natural resources under
their trusteeship.
Several preliminary design assumpti0ns and parameters are identified in the Design Criteria
Report (OCR) to support remedial design for the selected remedy at the Reasor Chemical site
(removal of soil from contaminated areas onsite and removal of sediment I water from four
ponds with subsequent backfilling, regrading, and revegetation). · Given the habitat value present
onsitc, we appreciate that Section 3.5 of the DCR (Long-Term Performance Monitoring and
Opero/ions and .Mair.tenance Requir~mCnts) identifies_revcgeta:io:1 of cxcavUtcd areas ·.-vith
native plants as a rernedial goal. Previously the Record of Decision (ROD)for the site (dated
September 2002) indicated that cover of regraded areas would incorporate both native vegetation
and crushed stone. We would be pleased to provide assistance in selection of appropriate plant
species and sources of plant material for site restoration activities. Consistent with the goal of
rcvegctation with native plant species, it is important to detail performance criteria for this
objective (e.g .. percent cover of desirable vegetation to be achieved in a given time period) in
future remedial design plans.
Section 3.6 of the DCR (Co111p/ia11ce 1Fi1'1 AI/Al/s, l'erlinent Codes. and Standards) presents the
assumption that remediation of onsitc ponds is uni ikcly to adversely impact jurisdictional
wetlands (to be verified by the U.S. Anny Corps 01· Engineers). According to Appendix D
• • f
(Wetland Delineation Report) of the Data Evaluation Summary Report, portions of all four onsite
ponds proposed for remediation satisfy wetland criteria. While these ponds are of man-made
origin, they I) provide essential habitat to a variety of aquatic-dependent species currently using
the site, 2) support functions and values of wetland or open water habitats, and.3) are
hydrologically linked to downgradient wetland areas (including onsite drainage ditches and
Prince George Creek). The Service believes that wetland and open water habitat values which
are degraded or lost as part of the remedial action for site clean-up shoul_d ultimately be restored.
Compensation for lost use of wetland and open water habitat functions and values of site ponds
and wetlands should be addressed through wetland mitigation and habitat restoration in future
remedial design plans. We would be pleased to further discuss evaluation and restoration of . .
wetland and aquatic habitats, including on-and off-site options, with you,-the responsible parties,
and site contractors in support of additional,remedial design planning,•«·'
The Service appreciates the opportunity to comment on the Design Criteria Report and the Data
Analysis Reporrfor the Reasor Chemical Company Site. If you have any questions or comments'·
regarding our recommendations, please contact me at 919/856-4520, (Ext. 30). If you would like
to discuss restoration of native plant communities onsite and/ or sources of plant material for
planning purposes, please contact Mr. Dale Suiter (Ext. 18), our staff botanist, for additional
information.

Re: Data Evaluation Report, Revision 1, Design Criteria Report, Revision 0
Reasor Chemical Company Site
Castle Hayne, North Carolina
Dear Ms. Urquart-Foster:
On July 21, 2003, CH2M HILL received a copy of the Data Evaluation Report,
Revision 1 and the Design Criteria Report, Revision 0. Ms. Hilda Dill and Ms. Jane
Sullivan have requested that CH2M HILL review these documents and provide
comments to EPA. The following letter provides CH2M HILL' s comments to these
documents.
Data Evaluation Report
1. Surface Water. The report provides the results of the surface water sampling .
conducted in March 2003. During field activities, EPA collected one discrete
sample for VOC TCLP analysis from Pond 2 and one composite sample from all
four ponds for TCLP metals and TCLP extractable organics analysis. All TCLP
results were below the quantitation limits and therefore, the report stated that
the surface water could be disposed of as non-hazardous waste.
Surface water samples from Ponds 3 and 4 were not evaluated for metals during
the Remedial Investigation and therefore, it is unknown if the surface water
concentrations in these ponds exceed the Clean-up Levels specified in the Record
of Decision (ROD). CH2M HILL recommends that the surface water from Ponds
3 and 4 be tested prior to removal to determine if there are exceedances of the
Clean-up Levels. If there are no exceedances, CH2M HILL recommends that
EPA investigate the feasibility of discharging the surface water from these ponds
onsitc. WESTON has estimated the surface water volume for Ponds 3 and 4 to
Dl:SIG/JCRI I EHIAOAT AEIJAI.LE ff ER.DOC
Ms. Urquart-Foster
Page2
July 30, 2003
• •
total 141,930 gallons. Using WESTON's estimated unit costs for surface water
transportation and disposal, onsite disposal of the water from Ponds 3 and 4
could reduce the total project costs by almost $30,000.
2. Groundwater Monitoring Schedule. Both the Design Criteria Report and the
Data Evaluation Report state plans to conduct groundwater monitoring on a
semi-annual basis. The Data Evaluation Report states intentions to collect
samples in September 2003. According to the ROD, groundwater is to be
monitored on an annual basis. For the reasons stated in the next section, if EPA
decides.to continue with groundwater monitoring for a five-year period, there is
certainly no justification to increase the monitoring frequency from the annual
. . sampiing specified in the ROD. . . . .
3. Amendment of ROD's Groundwater Monitoring Requirements. The data from
the most recent groundwater monitoring event is presented in the report. Of the
ten permanent monitoring wells and two production wells that were sampled,
only monitoring well MW-75 had an exceedance of a ROD-specified Clean-up
Level. The groundwater concentration in MW-75 exceeded the ROD-specified
Clean-up Level for aluminum. MW-75 was installed in March 2003 and this data
represents the first time that the well was sampled. The report stated the ·
fo)lowing in regards to the metals concentrations detected at MW-75:
"The elevated metals concentrations in groundwater sampled from MW-75
may be attributed to turbidity and low yield for this well. Another
contributing factor may be low pH. The pH for purge water from monitor
well MW-75 during development was 3.42. Following purge for sampling,
the pH was 2.31. If these field measurements accurately reflect the naturally
occurring pH for groundwater in this area and are not a artifact of recent well
installation and development acidity may be the primary reason dissolved.
metals were detected at elevated concentrations in groundwater sampled
from this area."
Aside from aluminum, thallium is the only other groundwater Chemical of
Concern listed in the ROD. The thallium results were not available at the time
the report was written, however EPA stated in its cover letter that all of the
thallium results were all below the maximum detection limit of 1 r1g/L.
CH2M HILL reviewed the groundwater monitoring well data collected during
the Remedial Investigation and in March 2003. With the exception of the
aluminum exceedance in MW-75 discussed above, there have been no
exceelfances of the ROD-specified Clean-up Levels in any other monitoring well.
The two groundwater COCs (Aluminum and Thallium) are naturally occurring
and were not detected in the onsite soils at significant concentrations.

Based on the i"ackof exceedances and the Jack of evidence that the groundwater
COCs are site-related, CH2M HILL recommends that the future groundwater
monitoring at the site be reduced. CH2M HILL recommends that monitoring
well MW-7S be redeveloped and resampled in March 2004 according to the
annual sampling frequency specified in the ROD. As no other well has ever
demonstrated concentrations of the COCs above the Clean-up Levels, there is no
justification for additional sampling at these wells. During the March 2004
sampling event, CH2M HILL recommends that particular attention be paid to
reduce the turbidity in this sample. If the turbidity can not be reduced to below
10 NTUs, a filtered sample should be collected as recommended by WESTON
(i:e_ collected through a device that enables the filtered and unfiltered samples to
be collected at the same time). The analysis of the March 2004 sample should be
limited to the ROD specified COCs -Aluminum and Thallium. If no
exceedances are detected in this sample, CH2M HILL recommends that the ROD
be amended and the groundwater monitoring program be stopped.
Design Criteria Report
·1. Revised Removal Volumes. EPA revised its estimate of the sediment volume to
be removed based on recent field measurements of the pond boundaries. This
resulted in a reduction of the estimated sediment removal volume from 1,252
cubic yards to 1,076 cubic yards. In addition, EPA revised its estimate of the
surface water volume to be removed based on recent field measurements of the
pond boundaries and surface water depth. This resulted in a reduction of the
estimated surface water removal volume of 526,592 gallons to 343,860 gallons.
The reduction in the sediment and surface water removal volumes will result in a
cost reduction for disposal and transportation of the affected media.
2. Construction of Access Roads. The report states that access roads will have to
be improved to accommodate truck traffic and that additional roads will have to
be installed to provide access to pond areas. Ms. Dill and Ms. Sullivan have
indicated that they intend to improve the roads between the property boundary
and the boundary of the Superfund Site. It is anticipated that these
improvements will be made when they implement the site security measures. It
is my understanding that EPA's comments on their proposal are being sent to
Bill Dannelly, the attorney for Ms. Dill and Ms. Sullivan. Mr. Dannelly reports
that he has not received those documents as of July 29.
!Vis. Jane Sullivan ,rnd Ms. Hilda Dill appreciate the opportunity to comment on the
above referenced reports. If you have any questions regarding the above
comments, please feel free to ml! Kelly Styncs at 919-363-4120 to discuss.

Dear Ms. Urquhart-Foster:
Thank you for your July 17, 2003 correspondence requesting U.S. Fish and Wildlife Service
(Service) review of the Design Criteria Report (Revision 0) and the Data Evaluation Report
(Revision 1) for the Reasor Chemical Company Site in Castle Hayne, New Hanover County, NC.
These comments are intended as technical assistance for the USEPA's assessments and planning
conducted pursuant to the Comprehensive Environmental Response, Compensation, and Liability
Act of 1980, as amended (42 U.S.C. 9601 et seq.); they do n_ot represent any position that the
U.S. Department of the Interior may adopt concerning possible injury to natural resources under
their trusteeship.
Several preliminary design assumptions and parameters-are identified in the Design Criteria
Report (DCR) to support remedial design for the selected remedy at the Reasor Chemical site
(removal of soil from contaminated areas onsite and removal of sediment I water from four
ponds with subsequent backfilling, regrading, and revegetation). Given the habitat value present
onsite, we appreciate that Section 3.5 of the DCR (Long-Term Performance Monitoring and
Operations and Maintenance Requirements) identifies revegetation of excavated areas with
native plants as a remedial goal. Previously the Record of Decision (ROD) for the site (dated
September 2002) indicated that cover of regraded areas would incorporate both native vegetation
and crushed stone. We would be pleased to provide assistance in selection of appropriate plant ·
species and sources of plant material for site restoration activities. Consistent with the goal of
revegetation with native plant species, it is important to detaii performance criteria for this
objective (e.g., percent cover of desirable vegetation to be achieved in a given time period) in
future remedial design plans ..
Section 3.6 of the OCR (Compliance with ARARs, Pertinent Codes, and Standards) presents the
assumption that remediation of onsite ponds is unlikely to adversely impact jurisdictional
wetlands (to be verified by the U.S. Army Corps of Engineers). According to Appendix D
• •
(Wetland Delineation Report) of the Data Evaluation Summary Report, portions of all four onsite
ponds proposed for remediation satisfy wetland criteria. While these ponds are of man-made
origin, they I) provide essential habitat to a variety of aquatic-dependent species currently using
the site, 2) support functions and values of wetland or open water habitats, and 3) are
hydrologically linked to downgradient wetland areas (including onsite drainage ditches and
Prince George Creek). The Service believes that wetland and open water habitat values which
are degraded or lost as part of the remedial action for site clean-up should ultimately be restored.
Compensation for lost use of wetland and open water habitat functions and values of site ponds
and wetlands should be addressed through wetland mitigation and habitat restoration in future
remedial design plans. We would be pleased to further discuss evaluation and restoration of
wetland and aquatic habitats, including on-and off-site options, with you, the responsible parties,
and site contractors in support of additional remedial design planning.
The Service appreciates the opportunity to comment on the Design Criteria Report and the Data
Analysis Report for the Reasor Chemical Company Site. If you have any questions or comments
regarding our recommendations, please contact me al 919/856-4520, (Ext. 30). If you would like
to discuss restoration of native plant communities onsite and/ or sources of plant material for
planning purposes, please contact Mr. Dale Suiter (Ext. 18), our staff botanist, for additional
information.
Sincerely,
Sara Ward

than in the unfiltered sample (39,000 µ.g/L vs 2,300 µ.g/L). The concentration of
aluminum was also significantly greater in the filtered sample than in the unfiltered
sample (440 J µ.g/L vs below detection limit of 21 J µ.g/L). In general, the other wells
