Re: Response to Comments -Monthly Progress and O&M Report -November, 1999
Macon/Dockery NPL Site
Cordova, North Carolina
Dear Ms. Bennett:
The Macon/Dockery Site Group (MDSG) Technical Committee is in receipt of your letter
dated January 3, 2000 regarding the North Carolina Department of Environment and Natural
Resources (NCDENR) review comments of the Monthly Progress Report for November, 1999.
Our consultant has prepared the following comments on behalf of the MDSG.
The numbered responses below correspond with the itemized comments contained in the
NCDENR January 3, 2000 letter. A copy of the NCDENR comment letters are attached to this
letter as Attachment I. A complete set of corrected tables reflecting the comments below has
been attached to this letter as Attachment 2. Other than the table modifications addressed in this
letter, no additional discrepancies were observed.
Response to Comments -
MONTHLY PROGRESS AND O&M REPORT -NOVEMBER, 1999
Results of Sampling and Testing and Other Data Received
I. Response: The table has been corrected to accurately reflect the Mass VOC Removal
for November and the Total VOC Removal Since Start-Up for the four groundwater
remediation systems.

6. Response: Duplicate samples are collected on the same day and at the same time that
the groundwater monitoring well is being sampled. A sample date or time for the
duplicate sample is not provided on the chain-of-custody so the laboratory can not
determine which monitoring well the duplicate sample was collected from. The
laboratory attaches an arbitrary date to the sample results for each of the duplicate
samples on the laboratory analytical report. A copy of the field sample form can be
provided should the NCDENR Superfund Section request such forms.
7. Response: Table 5 has been corrected to indicate that the groundwater sample
collected from monitoring well MW-9 on November 2, 1999 contained 0.59 ug/L
mercury.
8. Response: Table 5 has been corrected to indicate that the groundwater sample
collected on November 2, I 999 from groundwater monitoring well MW-9 (DUP-1)
contained 0.58 ug/L mercury.
9. Response: Table 5 has been corrected to indicate that the groundwater sample
collected from monitoring well MW-23 on November 3, 1999 contained no detectable
concentrations of mercury at a laboratory quantitation limit 0.20 ug/L.
I 0. Response: Table 5 has been corrected to indicate that the groundwater sample
collected from monitoring well MW-22 contained no detectable concentrations of I, I
dichloroethene at a laboratory quantitation limit of 1.0 ug/L.
11. Response: Table 5 has been corrected to indicate that the groundwater sample

13. Table 7 has been corrected to indicate the corrected groundwater elevation collected on
November 2, 1999 from monitoring well UD-5.
Table 8 Summary of Mass VOC Removal Estimates
9. Table 8 has been revised to reflect the corrected Average Total VOC Concentration for
November 1999 for the Upper/Lower groundwater remediation system. Additionally, the
table has been corrected to indicate the resulting Pounds ofVOC Removed for 1999 and
the Cumulative VOCs Removed.

RES UL TS OF SAMPLING AND TESTING AND OTHER DATA RECEIVED:
• Laboratory results for November sampling of the remediation systems are included in this
progress report. Tables I to 4 summarize the influent and effluent analytical results for the four
groundwater treatment systems. Manganese concentrations reported in the Lower Dockery
effluent sample in the previous month's status report have been reduced to concentrations below
the Remediation Performance Standard. All effluent concentrations reported in November 1999
are below the Remediation Performance Standards.
• Table 5 summarizes the groundwater analytical results of samples collected from monitoring
wells. Table 6 summarizes the analytical results of air samples. Table 7 summarizes the depth
to water measurements and groundwater elevations for monitoring and recovery wells. Table 8
summarizes the estimated mass removal of V OCs from the remedial systems.
The following table summarizes the remedial systems performance for November 1999:

Re: Response to Comments -Monthly Progress and O&M Report -August, 1999
Macon/Dockery NPL Site
Cordova, North Carolina
Dear Ms. Bennett:
The Macon/Dockery Site Group (MDSG) Technical Committee is in receipt of your letter
dated November I, 1999 regarding the North Carolina Department of Environment and Natural
Resources (NCDENR) review comments of the Monthly Progress Report for August, 1999. Our
consultant has prepared the following comments on behalf of the MDSG.
The numbered responses below correspond with the itemized comments contained in the
NCDENR November I, 1999 letter. A copy of the NCDENR comment letters are attached to
this letter as Attachment I. A complete set of corrected tables reflecting the comments below
has been attached to this letter as Attachment 2. Other than the table modifications addressed in
this letter, no additional discrepancies were observed.
Response to Comments -
MONTHLY PROGRESS AND O&M REPORT -AUGUST, 1999
Results of Sampling and Testing and Other Data Received

removed for the month of August for the Lower Dockery and Upper Dockery groundwater
remediation systems.

Table 3 Groundwater Quality Summary -Upper Macon Source Area
/3. Response: Table 3 has been corrected to reflect a result of 13 ug/L manganese for the
effluent sample collected from the Upper Macon Source Area on August 5, 1999.
Table 5 Groundwater Quality Summary
/4_ Response: Table 5 has been corrected to reflect that the groundwater sample collected
from monitoring well MW-I 6 was collected on August 6, 1999 .
./s. Response: Table 5 has been corrected to reflect that the groundwater sample collected
from monitoring well MW-I 6 on August 6, I 999 contained no detectable concentrations
of methylene chloide at a laboratory detection limit of 2.0 ug/L.
-6. Response: Table 5 has been corrected to indicate that the duplicate groundwater
sample collected on May 13, 1999 from groundwater monitoring well MW-2A and the
duplicate groundwater sample collected on August 6, 1999 from groundwater monitoring
well MW-2A contained no detectable concentrations of cadmium at a laboratory
quantitation limit of 0.30 ug/L.
/7. Response: Duplicate samples are collected on the same day and at the same time that
the groundwater monitoring well is being sampled. A sample date or time for the
duplicate sample is not provided on the chain-of-custody so the laboratory can not
determine which monitoring well the duplicate sample was collected from. The
laboratory attaches an arbitrary date to the sample results for each of the duplicate
samples on the laboratory analytical report. A copy of the field sample form can be
provided should the NCDENR Superfund Section request such forms.
/8. Response: Table 5 has been corrected to indicate that the groundwater sample
collected from monitoring well MW-13 on August 5, 1999 contained 0.25 ug/L mercury.
Table 8 Summary of Mass VOC Removal Estimates
9. Table 8 has been revised to reflect the actual Monthly Flow Volume and the Pounds of
VOC Removed and Cumulative VOCs Removed for August 1999 have been recalculated.

Results of Sampling and Testing and Other Data Received
I. The average flow rates given in the lahle included in this Section do not accurately reflect
the 31 days of operation. Furthermore, the Total Gallons Removed for August for the
Lower Dockery and Upper Dockery groundwater remedialion systems do not rcflccl the
amounts given in Table 8 (and are in fact the amounts given for May 1999). Please
correct these discrepancies.
Table 2 Groundwater Quality Summary -Lower Dockery
2. Table 2 indicates thal lhe Lower Dockery effluent sample collected on May 12, 1999
contained 13-µg/l chromium. However, laboratory documentation included in !he
Monlhly Progress and O&M Report • May 1999 indicates that the Lower Dockery
effluent sample collected on May 12, 1999 contained no detectable concentration.~ of
chromium (at a laboratory quantitation limit of 10-µg/l). Please clarify this discrepancy.
Table 3 Groundwater Qlllllity Summary -Upper Macon Source Area
3. Tahle 3 indicates that the Upper Macon Source Area effluent sample collected on August
5, 1999 conlained 12 micrograms per liter (µg/1) manganese. However, laboratory
documentation included in the Monthly Progress and O&M Report -August 1999
indicates that the Upper Macon Source Area emuent sample collected on August 5, 1999
contained 13-µg/l manganese. Please clarify this discrepancy.
Table 5 Groundwater Quality Summary
4. Table 5 indicates thut the groundwater sample from groundwater monitoring well MW-
16 was collected on Augu.~t 5, 1999. However, chain of custody documentation and
laboratory documentation included in the Monthly Progress and O&M Report -August
1999 indicute that the groundwater sample from groundwater monitoring well MW-16
was collected on August 6, 1999. Please correct this oversight.
5. Table 5 indicates thal 1he groundwater sample collected from groundwater monitoring
well MW-16 during the August 1999 sampling even! contained no detectable
concentrations of methylene chloride (at a laboratory quantiLation limit of 1.0-µg/l}.
However, laboratory documentation included in the Monthly Progress and O&M Report •
August 1999 indicates that the groundwater sample collected from groundwater
monilt>ring well MW-16 during the August 1999 sampling event contained no detectable
concentrations of methylene chloride (at a laboratory quantitation limit of 2.0-µg/1).

from groundwater monitoring well MW-2A (DUP-2) contained no deteclable
concentrations of cadmium (at a laboratory quantitation limit of 0.30-µg/l). Please clarify
these discrepancies.
7. Table 5 indicates 1hat the duplicate groundwater sample from groundwater monitoring
well MW-9 (DUP-1) was collected on August 5, 1999, However, laboratory
documentation included in the Monthly Progress and O&M Report • August 1999
indicates that the groundwater sample from groundwater monitoring well MW-9 was
collecled on August 5, 1999 and that the duplicate groundwater sample from groundwater
monitoring well MW-9 (DUP-1) was collected on August 6, 1999. Please clarify these
discrepancies.
8. Table 5 indicates that lhe groundwater sample collcc1cd on August 5, 1999 from
groundwater monitoring well MW-13 containe<l no detectable concentrations of mercury
(at a lahoralory quantitation limit of 0.20-µg/l), However, laboratory documentation
included in the Monthly Progress and O&M Report -August I 999 indicates that the
groundwater sample collected on August 5. 1999 from groundwater monitoring well
MW-13 contained 0.25-µg/l mercury. Please clarify this discrepancy.

On behalf of the Macon/Dockery Site Group ("Group"), the August 1999 Monthly Progress and
O&M Report is herewith submitted in accordance with SECTION XV -PROGRESS REPORTS of
the Unilateral Administrative Order (effective date -June 30, 1992) for the Macon/Dockery Site.
This report describes activities that occurred during the month of August as part of the Remedial
Action phase of this project.
PROJECT TASKS INITIATED OR COMPLETED THROUGH AUGUST 1999:
• Quarterly influent and effluent sampling of the remediation systems
• Quarterly sampling of twelve monitoring wells
• Continued O & M of the systems
RESULTS OF SAMPLING AND TESTING AND OTHER DATA RECEIVED:
• Laboratory results for August sampling of the remediation systems are included in this progress
report. Tables 1 to 4 summarize the influent and effluent analytical results for the four
groundwater treatment systems. All effluent concentrations are below the Remediation
Performance Standards.

PROBLEMS AND DELAYS:
•
• August 20 through August 27, 1999 -the Lower Dockery and Macon Source Area systems were
down due to the control panel programming being damaged from an apparent electrical storm
or power surge. The systems were reprogrammed and operating on August 27, 1999.
• Percent operational for each system:

Table 2 Groundwater Quality Summary -Lower Dockery
1. The portion of Table 2 that reflects the Lower Dockery groundwater remediation system
effluent sample results was inadvertently omitted. Please correct this oversight.
Table 5 Groundwater Quality Summary
2. Table 5 indicates that the duplicate groundwater sample collected on May 13, 1999 from
groundwater monitoring well MW-2A (DUP-2) contained no detectable concentrations of
cadmium (at a laboratory quantitation limit of 3.0-µg/l). However, laboratory
documentation included in the Monthly Progress and O&M Report -May 1999 indicates
that the duplicate groundwater sample collected on May 13, 1999 from groundwater
monitoring well MW-2A (DUP-2) contained no detectable concentrations of cadmium (at
a laboratory quantitation limit of 0.30-µg/l). Please clarify this discrepancy.

The Macon/Dockery Site Group (MDSG) Technical Committee is in receipt of your letter
dated July 23, 1999 regarding the North Carolina Department of Environment and'Natural
Resources (NCDENR) review comments of the Monthly Progress Report for May, 1999. Our
consultant has prepared the following comments on behalf of the MDSG.
The numbered responses below correspond with the itemized comments contained in the
NCDENR July 23, 1999 letter. A copy of the NCDENR comment letters are attached to this
letter as Attachment 1. A complete set of corrected tables reflecting the comments below has
been attached to this letter as Attachment 2. Other than the table modifications addressed in this
letter, no additional discrepancies were observed.
Response to Comments -
May 1999 MONTHLY PROGRESS AND O&M REPORT
Table 1 Groundwater Quality Summary -Upper Dockery
I. Response: "NS -Not Sampled" has been added to Table I to indicate that a sample
was not collected during a particular sampling event.
Table 2 Groundwater Quality Summary -Lower Dockery
2. Response: The MDSG agrees with NCDENR's interpretation of the laboratory
analytical results collected from the influent/effluent ports on February 11,
1999 at the Lower Dockery groundwater remediation system. However,
Ms. Giezelle Bennett

3. Response:
4. Response:
• •
the laboratory is unable to confirm that the sample containers were
inadvertently switched in the field. A system effluent sample was
collected in March, 1999 to verify the analytical results. Analytical results
from the March, 1999 monthly system sampling event indicated no
detectable amounts of volatile organic compounds present in the water
sample collected from the Lower Dockery effluent sample port. The
results of the March, 1999 effluent sampling indicates that the February
influent and effluent samples were inadvertently switched in the field.
Due to the apparent field error, the average total voe was calculated
using the influent analytical results. Table 2 has been coirected to
illustrate the reversed analytical results and a footnote has been added to
the bottom of the table to explain the error. The associated laboratory
analytical results from the March monthly sampling event were included
in the March, 1999 Monthly Progress and O&M Report.
The footnote "Note: A blank means below detection limit" has been
deleted from Table 2.
Table 2 has been corrected to reflect a result of <IO micrograms per liter
(ug/L) chromium for the effluent sample collected from the Lower
Dockery groundwater remediation system on May 19, 1999.
Table S Groundwater Quality Summary
5. Response: Table 5 has been revised to reflect that the duplicate groundwater sample
collected on May 13, 1999 from groundwater monitoring well MW-2A
(DUP-2) contained no detectable concentrations of cadmiul!I at a
laboratory detection limit of 0.30 ug/L.

Response:
' Since it is apparent that the influent and effluent samples collected from
the Lower Dockery groundwater remediation system on February 11, 1999
were inadvertently switched in the field, the effluent analytical data was
utilized to calculate the average total volatile organic compound
concentrations as indicated in Response Number 2.
Table 8 has been revised to reflect the correct voes Removed data for
April and May for the four groundwater remediation systems.

2. Table 2 correctly reflects the February 11, 1999 laboratory analylical data for lhe Lower
Dockery groundwater remediation system influenl and effluenl samples. However, it
appears that the samples were incorrect! y labeled al the time of sampling. The volatile
organic compound (Voe) analyses of these two samples indicate that the influent ~ample
contained no detectable concentrations of voe~. yet the effluent sample contained 35.2
micrograms per liter (µg/1) total voes. Plen~e clarify this discrepancy,
3. Please delete the note "Note: A blank means below detection limil" contained in Table 2.
4. Table 2 indicates th111 the Lower Dockery effluent sample collected on May 12, 1999
contained 13-µg/1 chromium. However, laboratory documentation included in the
Monthly Progress and O&M Report • May 1999 indicates that the Lower Dockery
effluent sample collected on May 12, 1999 contained no detectable conccntralions of
chromium (at u laboratory quuntitation limit of 10-µg/l). Please clarify this discrepancy.
TableS Groundwater Quality Summary
5. Table 5 indicates 1ha1 the duplicate groundwater sample collected on May 13, 1999 from
groundwater monitoring well MW-2A (DUP-2) contained no detectable concentrations of
cadmium (at a laboratory quantitation limit of 3.0-µg/1). However, laboratory
documentation included in the Monthly Progress and O&M Report -May l 999 indicates
that the duplicate groundwater sample collected on May 13, 1999 from groundwater
monitoring well MW-2A (DUP-2) contained no detectable concentrations of cadmium (at
a laboratory quantitation limit of0.30-µg/l). Please clarify this discrepancy.

6. Table 8 should be revised to reflect the response to comment #2 a.hove. Please correct
Table 8 as well as the table included in the section entitled, Rcsulls of Sampling and
Testing and Other Datu Received.
7. The April 1999 and May 1999 Cumulative voes Removed data for all four groundwater
remediation systems are incorrect. Please correct Table 8 a~ well as the table included in

I. The firs! page of Table 2 was duplica1ed and the second page of Table 2 was
inadvenently omitted. Please correct this oversight.
2. Table 2 indicates that the Lower Dockery effluent sample collected on May 12, I 999
contained 13 micrograms per liter (µgn) chromium. However, laboratory documentation
included in the Monthly Progress and O&M Report -May 1999 indicates that the Lower
Dockery effluent sample collected on May 12, 1999 contained no detectable
concentrations of chromium (al a laboratory quantitation limit of IO-µg/1). Please clarify
this discrepancy.

Table I Groundwater Quality Summary -Upper Dockery
I. Please define the abbreviation "NS" contained in Table 1.
Table 2 Groundwater Quality Summary -Lower Dockery
2. Table 2 correctly reflects the February 11, 1999 laboratory analytical data for the Lower Dockery groundwater remediation system influent and effluent samples. However, it appears that the samples were incorrectly labeled at the time of sampling. The volatile organic compound (VOC) analyses of these two samples indicate that the influent sample contained no detectable concentrations of VOCs, yet the effluent sample contained 35.2 micrograms per liter (µg/1) total VOCs. Please clarify this discrepancy.
3. Please delete the note "Note: A blank means below detection limit" contained in Table 2.
4. Table 2 indicates that the Lower Dockery effluent sample collected on May 12, 1999 contained 13-µg/I chromium. However, laboratory documentation included in the Monthly Progress and O&M Report -May 1999 indicates that the Lower Dockery effluent sample collected on May 12, 1999 contained no detectable concentrations of chromium (at a laboratory quantitation limit of 10-µg/l). Please clarify this discrepancy.
Table 5 Groundwater Quality Summary
5. Table 5 indicates that the duplicate groundwater sample collected on May 13, 1999 from groundwater monitoring well MW-2A (DUP-2) contained no detectable concentrations of cadmium (at a laboratory quantitation limit of 3.0-µg/1). However, laboratory documentation included in the Monthly Progress and O&M Report -May 1999 indicates that the duplicate groundwater sample collected on May 13, 1999 from groundwater monitoring well MW-2A (DUP-2) contained no detectable concentrations of cadmium (at a laboratory quantitation limit of0.30-µg/l). Please clarify this discrepancy.
Table 8 Summary of Mass VOC Removal Estimates
6. Table 8 should be revised to reflect the response to comment #2 above. Please correct Table 8 as well as the table included in the section entitled, Results of Sampling and Testing and Other Data Received.
7. The April 1999 and May 1999 Cumulative VOCs Removed data for all four groundwater remediation systems are incorrect. Please correct Table 8 as well as the table included in the section entitled, Results of Sampling and Testing and Other Data Received.

I. The first item of this section states that all effiuent concentrations are below the
Remediation Performance Standard. However, Table 3 indicates that the Upper Macon
Source Area (UMSA) exceeded the performance standard for manganese in May 1998.
The Superfund Section recognizes that the March 28, 1995 letter from Ms. Giezelle
Bennett to Mr. Kenny Gulledge provides for the discharge of treated groundwater to the
onsite infiltration gallery without treating for manganese. Please revise this report to
reflect the manganese exceedance as well as the discharge requirements of the NC DENR
Division of Water Quality.
2. The last item in this section states that the Upper/Lower Macon flow meter reading for
May 1998 totaled 875,945 gallons. However, Table 8 indicates that the Upper/Lower
Macon system had a total discharge of 876,945 gallons for May 1998. Please clarify this
discrepancy. Please correct the pounds of volatile organic compound (VOC) removed for
May 1998 if the value given in Table 8 is in error.
3 . The last item in this section states that the Upper Macon system was operational 87% of
the time in May 1998 and that the Lower Macon system was operational 77% of the time
in May 1998. However, based on the information provided in the section entitled,
Problems and Delays, the Upper Macon system was operational 90% of the time in May
1998 and the Lower Macon system was operational 84% of the time in May 1998. Please
clarify this discrepancy.
4. The average discharge rates given for each of the four groundwater remediation systems
do not agree with the total discharge rate and operational percentage given for each
system. Please clarify these discrepancies.

Table 5 Groundwater Quality Summary
•
12. Table 5 indicates that the groundwater sample collected from the groundwater monitoring
well MW-15 on February 5, 1998 contained 0.7 µg/1 mercury. However, laboratory
documentation indicates that the MW-15 groundwater sample contained 0.66 µg/1
mercury. Please clarify this discrepancy.
13. Table 5 indicates that the groundwater sample collected from the groundwater monitoring
well MW-15 on May 6, 1998 contained 0.8 µg/1 mercury. However, laboratory
documentation indicates that.the MW-15 groundwater sample contained 0.76 µg/1
mercury. Please clarify this discrepancy.
14. Table 5 indicates that the duplicate groundwater sample (DUP-1) collected from the
groundwater monitoring well MW-15 on February 5, 1998 contained 0.6 µg/1 mercury.
However, laboratory documentation indicates that the MW-15 duplicate groundwater
sample contained 0.63 µg/1 mercury. Please clarify this discrepancy.
Table 6 Air Quality Summary
15. The results of the air sampling conducted along the property line on May 7, 1998 were
inadvertently omitted from Table 6. Please correct this oversight.
16. Table 6 indicates that air sampling was not conducted at sample points VE-01, OW-I,
OW-3 and OW-5 during the May 1998 sampling event. Please provide justification for
not collecting air quality samples at these sampling points or provide a schedule for
completing this task .

The Macon/Dockery Site Group (MDSG) Techriical Committee is in receipt of your letter
dated June 3, 1999 regarding the North Carolina Department of Environment and Natural
Resources (NCDENR) review comments of the Monthly Progress Report for April, 1999. Our
consultant has prepared the following comments on behalf of the MDSG.
The numbered responses below correspond with the itemized comments contained in the
NCDENR June 3, 1999 letter. A copy of the NCDENR comment letters are attached to this
letter as Attachment 1. A complete set of corrected tables reflecting the comments below has
been attached to this letter as Attachment 2. Other than the table modifications addressed in this
letter, no additional discrepancies were observed.
Response to Comments -
APRIL 1999 MONTHLY PROGRESS AND O&M REPORT
Table 1 Groundwater Quality Summary -Upper Dockery
✓l. Response: Per AES' conversation with Ms. Oiezelle Bennett, the Upper Dockery
system effluent results collected on February 13, February 14, and
February 14 (duplicate) and February 15, 1996 were removed from Table
I to fit the most recent results on to one page. Please refer to the historical
Groundwater Quality Summary data contained in previous reports.

system effluent results collected on February 13, February 14, and
February 14 (duplicate) were removed from Table 2 to fit the most recent
results on to one page. Please refer to the historical Groundwater Quality
Summary data contained in previous reports.
3. Response: The MDSG agrees with NCDENR's interpretation of the laboratory
analytical results collected from the influent/effluent ports on February 11,
1999 at the Lower Dockery groundwater remediation system. However,
the laboratory is unable to confirm that the sample containers were
inadvertently switched in the field. A system effluent sample was
collected in March, 1999 to verify the analytical results. Analytical results
from the March, 1999 monthly system sampling event indicated no
detectable amounts ofvolatile·organic compounds present in the water
sample collected from the Lower Dockery effluent sample port. The
results of the March, 1999 effluent sampling indicates that the February
influent and effluent samples were inadvertently switched in the field.
Due to the apparent field error, the average total VOC was calculated
using the influent analytical results. Table 2 has been corrected to
illustrate the reversed analytical results and a footnote has been added to
. the bottom of the table to explain the error. The associated laboratory
analytical results from the March monthly sampling event were included
in the March, 1999 Monthly Progress and O&M Report.

)9. Response:
Since it is apparent that the infludnt and effluent samples collected from
the Lower Dockery remedial system on February I I, 1999 were
inadvertently switched in the field, the effluent analytical data was utilized
to calculate the average total volatile organic compound concentration as
indicated in Table 5. )

A copy of the chain-of-custody record for the April 8, 1999 sampling
event has been attached for your review.

I I The MDSG appreciates the EPA's and NCDENR's careful review of the Monthly Progress and
O&M Reports. Future reports submitted by the MDSG will incorporate the changes and
additions addressed in the comments above.

Section recognizes that the March 28, 1995 letter from Ms. Giezelle Bennett to Mr.
Kenny Gulledge provides for the discharge of treated groundwater to the onsite infiltration
gallery without treating for manganese. However, this section should be revised to reflect

I 7. Table S does not reflect the results of the groundwater sample collected from groundwater
monitoring well MW-23 on February 5, 1998. Please correct this oversight.
18. Table 5 indicates that the groundwater sample collected from the groundwater monitoring
well MW-9 on February 5, I 998 contained no detectable concentrations of acetone above
a laboratory quantitation limit of 50 µg/1 However laboratory documentation. indicates
that this groundwater sample was analyzed at a laboratory quantitation limit of I 00 µg/1.
Please clarify this discrepancy.
19. Table 5 indicates that the groundwater sample collected from the groundwater monitoring
well MW-I I on November 13, 1997 contained 45 µg/1 zinc. However, laboratory
documentation indicates that the MW -11 groundwater sample contained 20. 7 µg/1 zinc.
Please clarify this discrepancy.
20. Table S indicates that the groundwater sample collected from the groundwater monitoring
well MW-19 on February S, 1998 contained 82 µg/1 zinc. However, laboratory
documentation indicates that theMW:19 groundwater sample contained no detectable
concentrations of zinc. Please clarify this discrepancy.
21. Table S indicates that the groundwater sample collected from the groundwater monitoring
well MW-13 on November 11, 1997 was not analyzed for suspended solids content.
However, laboratory documentation indicates that the MW-13 groundwater sample
contained 84 mg/I suspended solids. Please clarify this discrepancy.
Table 6 Air Quality Summary
22. The note at the bottom of Table 6 indicates that blank entries signify analysis results that
are beneath laboratory detection limits. As staled in previous correspondence, please
denote the actual detection limit (e.g., <IO, <2.0) in order to prevent any confusion or
misrepresentations of the data. Entries in which no analyses were conducted should be
clearly indicated on the tables as well. Please make the appropriate modifications.
23. The results of the November 13, 1997 and February 6, 1998 air sampling activities at air
sampling locations VE-01, OW-I, OW-3 and OW-5 have been inadvertently omitt4<d from
Table 6. Please correct this oversight.
24. Table 6 indicates that the Upper Dockery Air Stack air sample collected on August 7,
1997 contained 2 mg/m3 toluene. However, laboratory documentation indicates that the
Upper Dockery Air Stack air sample contained no detectable concentrations of toluene.
Please clarify this discrepancy.

On behalf of the Macon/Dockery Site Group ("Group"), the January 1998 Monthly Progress and 0
& M Report is herewith submitted in accordance with SECT! ON XV -PROGRESS REPORTS of
the Unilateral Administrative Order ( effective date -May 30, 1992) for the Macon/Dockery Site.
This report describes activities which occurred during the month of January as part of the Remedial
Action phase of this project.
PROJECT TASKS INITIATED OR COMPLETED THROUGH JANUARY 1998:
• Monthly sampling of the water effluent from the remediation systems.
• Continued O & M of systems.
RESULTS OF SAMPLING AND TESTING AND OTHER DATA RECEIVED:
• A summary of the laboratory results for January sampling of the remediation systems is
included in this progress report. Tables I through 4 summarize the analytical results for the
four groundwater treatment systems. The reported effluent concentrations are below the
remediation performance standard.

• Upper Dockery flow meter reading for January totaled I 03,968 gallons. The system was
operational 58% of the time avernging 1.90 gallons per minute (GPM). Mass VOC removal
· was 0.09 pounds for the month and the cumulative is 7.64 pounds.
• Lower Dockery flow meter reading for January totaled 786,548 gallons. The system was
operational 100% of the time averaging 14.37 GPM. Mass VOC removal was 0.41 pounds
for the month and the cumulative is 6.84 pounds.
Macon Source Area flow meter malfunctioned in January. An estimate of the total flow,
based on the flow rate for the two (2) site visits prior to the malfunction, is approximately
178,387 gallons. The system was operational 100% of the time averaging 3.26 GPM.
Mass VOC removal was 0.18 pounds for the month and the cumulative is 2.32 pounds.
o Upper/Lower Macon flow meter.reading for January totaled 531,692 gallons. The Upper
Macon system was operational 71 % of the time in January. The Lower Macon system was
operational 71% of the time in January. The combined system flow averaged 9.71 GPM.
Mass VOC removal was 0.07 pounds for the month and the cumulative is 2.97 pounds.
TASKS PLANNED FOR FEBRUARY 1998:
o Monthly sampling of the remediation system effluents
o Quarterly samp)ing of the designated monitoring wells and system influents.
Continue O &M of systems
o The MDSG will review the options for treatment of the Upper/Lower Macon infiltration
galleries
PROBLEMS AND DELAYS:
e January 2, 9, 16, 23, 30, 1998 -The Upper Dockery Remedial System was down on these
days due to a high water level alarm in the airstripper sump. The transfer pump was found
to be frozen on January 2, 1998, causing the airstripper sump to experience a high water level
alarm. On the other dates the transfer pump appeared to have lost prime. After a manual
restart, the system performed correctly when the O&M contractor left the site. In addition,
the O&M contractor installed a check valve immediately downstream of the transfer pump
in an attempt to keep the transfer pump prime. The problem with the transfer pump loss of
prime is continuing to be investigated.

• •
• January 12, 1998 -The Upper/Lower Macon System was down because of a line leak
detected by the O&M contractor during a site visit.• The leak was in a pipe between the
airstripper and metals treatment unit. Parts were ordered and installed to repair the leak and
the system was restarted on January 23, I 998.
· o Groundwater extraction well UM-6 remained in an off-line condition at the end of the
January reporting period because of high water levels observed in the Upper/Lower Macon
infiltration galleries. The DENR requested that chlorine not be used for treating the
infiltration galleries and that chemicals such as hydrogen peroxide, acetic acid, or citric acid
be considered as options. The MDSG is considering the various options and the appropriate
dosages. A recommendation should be made to the EPA, under separate cover, in February
regarding this issue.
111 January 16, 1998 -The flow meter at the Upper Macon Source Area was observed to be
malfunctioning. The flow meter has been removed and sent to the manufacturer for repair.
January 2, 16, 30, 1998 -The soil vapor extraction (SVE) system was found to be down on
these days by the O&M contractor because of a high water level condition in the moisture
knock-out tank. The high water level condition is due to the large amount of precipitation
received in January and sedimentation collecting in the tank. The tank was cleaned out on
January 30, 1998.

The Macon/Dockery Site Group (MDSG) Technical Committee is in receipt of your letter
dated December I 0, 1998 regarding the North Carolina Department of Environment and Natural
Resources (NCDENR) review comments of the Monthly Progress Report for October of 1998.
Our consultant has prepared the following comments on behalf of the MDSG.
The numbered responses below correspond with the itemized comments contained in the
NCDENR December 10, 1998. A copy of the NCDENR comment letters are attached to this
letter as Attachment I. A complete set of corrected tables reflecting the comments below has
been attached to this letter as Attachment 2. Other than the table modifications addressed in this
letter, no additional discrepancies were observed.
Response to Comments -
SEPTEMBER/OCTOBER 1998 MONTHLY PROGRESS AND O&M REPORTS
Results of Sampling and Testing and Other Data Received
I. Response: AES arrives at the average discharge rate by dividing the
total gallons pumped during the period by the total number of minutes in
the period, thus resulting in an average discharge rate for the period. The
system operation percentage is not a factor in AES' calculation for a
discharge rate. AES believes that the discharge rates for the remedial
systems documented in the October, 1998 report accurately indicates the
approximate average discharge rate for the month. AES will include the
dates that the totalizer flow meter readings are collected in the Monthly
2.
• •
Progress and O&M reports. The December Monthly Progress and O&M
Report will be the first report to include the collection dates for the !low
meter readings.
Response: According to our records, both sections of the October
Monthly Progress and O&M Report referenced in the NCDENR lctkr
indicate that the Upper/Lower Macon ground water remediation system
was operational 100% of the time in October.
Table 2 Groundwater Quality Summary -Lower Dockery
Response: Table 2 has been corrected to indicate a result of 140
micrograms per liter (ug/L) for manganese in the eflluent sample collected
from the Lower Dockery remediation system on October 2, 1998.
Table 5 Groundwater Quality Summary
4.
5.
Response: The Upper/Macon flow meter reading for May, 1998
totaled 876,945 gallons as indicated in Table 8. The text has been revised
to illustrate the correct flow meter reading.
Response: The calculation error for the average volatile organic
compound (VOC) concentrations for August, 1998, September, 1998, and
October, 1998 has been corrected. The attached Table 8 reflects the
correct average VOC concentration and cumulative VOC removal amount.
The MDSG appreciates the EPA's and NCDENR's careful review of the Monthly Progress and
O&M Reports. Future reports submitted by the MDSG will incorporate the changes and
additions addressed in the comments above.
Should you have any questions or need additional information, please do not hesitate to
contact me.

MONTHLY PROGRESS AND O&M REPORT-SEPTEMBER 1998 Results of Sampling and Testing and Other Data Received
I. The monthly average discharge rates for the groundwater remediation systems do not agree with the total monthly discharge and the operational percentage provided for the groundwater remediation systems. PlcaRe correct these oversights. It is suggested that the Monthly Progress and O&M Ropons be revised to include the date that tho total flow reading is taken in order to accurately calculate the flow rate.
2. The fifth item in this section state~ that the Upper/Lower Macon groundwater remediation system was operational 95% of October. However, the second item of the section entitled, Problem~ and Delays, states that the Upper/Lower Macon groundwater remediation system WIili operational 100% of October. Please clarify this discrepancy.
Table 2 Groundwater Quality Summary -Lower Dockery
3. Table 2 indicates that the Lower Dockery groundwater remediation system effluent
sample collected on October 2, l 998 contained no detectable concentrations of manganese (in excess of the 5 micrograms per liter (µg/1) laboratory detection limit). However, the laboratory documentation included in the October 1998 Monthly Progress and O&M Rep011 indicates that the Lower Dockery emuent sample collected on October 2, 1998 contained 140 µg/1 manganese, Please claiify this discrepancy.
Table S Summary of Mass VOC'Removal Estimates
4. Table 8 indicates that the Upper/Lower Macon flow meter reading for May 1998 totaled 876,945 gallons. This infonnation .agrees with the data presented in Table 8 of the Monthly Progress and O&M Report -May 1998 (May 1998 Report) and Table 8 of the Annual Summary Status Repo11 -June 1997 to June 1998. However, the section entitled, Results of Sampling and Testing and Other Data Received, of the May 1998 Report indicates that the Upper/Lower Macon system had a total discharge of875,945 gallons for May 1998. Please clarify this discrepancy.
S. Tho average total volatile organic compound (VOC) concentrations given for the August 1998, September 1998 and October 1998 sampling events conducted at the Upper/Lower Macon groundwater remediation system in Table 8 are incorrect. The error appears to be that the Lower Macon remediation ~-ystem contained 3.5 µg/1 trichlorocthylene, not 35 µgll as rcponed in Table 4 of the Monthly Progress and O&M Rcpol1 -August l 998. Please correct these oversights.

Response to Comments -
November & December 1997 Monthly Progress and O&M Reports
Attachment 5 Table 5 -Groundwater Quality Summary
1. The response to comment #4 states that Table 5 has been corrected to show the correct
mercury concentration of0.66 micrograms per liter (µg/1) for the water sample collected
February 5, 1998 from monitoring well MW-15. However, Table 5 indicates that the
water sample collected February 5, 1998 from monitoring well MW-15 contains 0.7 µg/1
mercury. Please correct this oversight.
Attachment 8 Table 2 -Groundwater Quality Summary
2. The response to comment #IO states that Table 2 has been corrected to show the sample
collected December 5, 1996 from the Lower Dockery effluent to be "not analyzed" for
zinc content. However, this comment references the Lower Dockery effluent sample
collected on December 5, 1997. Additionally, laboratory documentation submitted in the
March 1998 Monthly Progress and O&M Report indicates that the Lower Dockery
effluent sample collected on December 5, 1997 contained no detectable concentrations of
zinc (laboratory quantitation limit -20 µg/1). Please correct Table 2 to indicate the
analytical result for zinc to be <20 µg/l for the Lower Dockery effluent sample collected
onDecember5, 1997.

Table I Groundwater Quality Summary
4. The response to comment #2 states that Table 1 was corrected to indicate a barium
concentration of 67.9 µg/l for the water sample collected November 13, 1997 from the
Upper Dockery effluent. However, Table 1 indicates that the Upper Dockery effluent
sample collected on November 13, 1997 contained 55.6 µg/l barium rather than 67.9 µg/1
barium as the laboratory documentation indicates. Please correct this oversight.

remediation systems appear to be in error. These values should be recalculated, especially
for the Upper Dockery and Upper/Lower Macon groundwater remediation systems which
may have incorrect operational percentages for January 1998. Please provide the
methodology that is used to calculate the flowrates for the four groundwater remediation
systems.
21. The cumulative mass volatile organic compound (VOC) removal rates given for the four
groundwater remediation systems do not agree with the values given in Table 8, included

SUPERFUND SEG'\ ION
The Macon/Dockery Site Group (MDSG) Technical Committee is in receipt of your letter
dated April 24, 1998, regarding the North Carolina Department of Environment and Natural
Resources (NCDENR) review comments of Monthly Progress Reports November 1997,
December 1997, and February 1998. Our consultant has prepared the following comments on
behalf of the MDSG.
The numbered resp0nses below correspond with the·itemized comments contained in the
NCDENR March 20, 1998 letter. A copy of the NCDENR comment letter is attached to this
letter as Attachment I. A complete set of corrected tables reflecting the comments below has
been attached to this letter as Attachment 2. Monthly Progress Reports for January, March, and
April 1998 were reviewed for typographical and transcription errors in addition to the corrections
referred to in this letter. Other than the table modifications addressed in this letter, no additional
discrepancies were observed.
A copy of the January 1998 monthly status report with tables reflecting the corrections
from this report is attached to this letter as Attachment 3. Please note that the monthly mass
removal estimate calculations were revised in March 1998. Therefore; monthly status reports
previous to March 1998 report slightly different results for mass removal estimates.
