IND SE_CI!Or,i 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 ·1i1!Hrn0t Addross (URL)., htt1r//wwy,,.epa.go\i ~ :l>o~1IH••-yci;,ibl,: .. )'"r,t,:J wi:t Vegetnblu·Oil f:lr1.o;;id h1ks (m-Re.;ycitJd P..tper {Minimum Jl:J% f>os1co11surneq ...-; 1·~.-~·~"::"'\'t,,, ~-• '. • Page 2 most likely contain concentrations of at least one inorganic compound in exceedance of the clean-up levels.

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.

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.

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. • North Carolina Department of Environment and Natural Resources Michael F.

" U.S. Envjronmental Protection Agency Atlanta Feiferal Center 6 I Forsyth Street Atlanta, Georgia 30303-8960 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).

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. OESIGNCRI I ERIAOAT AEVALLET1 ER DOC ·•, ' ... . ' \.• Ms. Urquart-Foster Page3 July 30, 2003 • • 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.

Waste Management Divsion U.S. Environmental Protection Agency Allanta Federal Center 61 Forsyth Street Atlanta, Georgia 30303-8960 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.

Table 4-3 indic1tcs that there was an obstruction i,1 PW-2. Please correct the error in the appropriate place. 3. Sections 4.6.2 and 5.2-Arsenic was detected at 41 µ.g/L, which is above the Maximum Contamin;nt Level (MCL), in the filtered sample from ·well MW-2, but was below the detection limit of 3.7 /tg/L in the unfiltered sample from this same well. The.concentration of Iron was also significantly greater in the filtered sample\.\ 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 that had both filtered and unfiltered samples showed similar concentrations or the filtered result was less than unfiltered result. Please discuss this uncertainty/anomaly for well MW-2 in section 5.2 j 4. Table 4-4, sample MW-2 -The Field Data Sheet found in Appendix C for well MW- 2 indicated the turbidity was 476 NTU at the sample time. Table 4-4 lists the turbidity for this well as 20.7 NTU. According to the Field Data Sheet in Appendix C, 20.7 NTU was the turbidity reading just before the well purged clry. Please correct Table 4-4. Js.
