6. Response: Acknowledged. The title of Table 5 has been revised to read
I "Groundwater Quality Su.mmary" . A copy of the corrected Table 5 for May 1997 is attached to
this letter.
7. Response: Acknowledged. Since ethylbenzene has not been a target parameter of the
groundwater sample analyses, and since it is not a parameter included in the Performance
Standard Verification Plan for groundwater; ethylbenzerie has been removed from Table 5. A
copy of the corrected Table 5 for May 1997 is attached to this letter. ·
8. Response: Adrnowledged. Table 5 has been revised'to indicate parameters that were
"not analyzed" as NA. A'. copy of the corrected Table 5 for May 1997 is attached to this letter.

9. Response: D~plicate sample DUP-2 was collected May 12, 1997, from well MW-IS.
Table S has been revised to include the analytical results from sample DUP-2 appropriately under
the analytical results for well MW-IS. A copy of the corrected Table S for May 1997 is attached
to this letter.
I
10. Response: Th~e samples designated Macon MN MID (collected from the Upper/Lower
Macon midfluent) and Lo MN MID (collected from the Lower Dockery System midfluent) were
collected from a sample port located between the metals treatment canisters at the Upper/Lower
Macon system and Lowet Dockery system, respectively. As these samples were collected only
for information regarding1 the performance of the first in-series metal canister, the results were not I •
tabulated in the status report. In the future, AES will summarize the analytical results of
· midfluent data on a separate table. A copy of the current midfluent table is attached to this letter.

Monthly Progress and O&M Report
June 1997
Table 3 Groundwater Quality Survey
12. Response: The system performance text has been revised to indicate the exceedance
of the manganese concen,tration performance standard. A copy of the corrected text is attached
to this letter.
13. Response: Acknowledged. Table 3 has been revised to indicate parameters that were
"not analyzed" as NA. A copy of the corrected Table 3 for June 1997 is attached to this letter.
Table 6 Air _Quality Summary
14. Response: Q'uarterly air sampling is conducted at offgas stacks and the property line.
During the May 1997 qu~rterly event, however, AES field personnel did not collect air samples
from the soil vapor extraction (SVE) system or from the Lower Dockery or Property Line
locations. The reason for not sampling these locations was because the SVE system and Lower
Dockery systems were not operative. The Property Line location was not sampled since the SVE
system was not operative and therefore not contributing to the total offgas of the Macon site.
The June 1997 air sampling locations represent the balance of what was not sampled during the
May Quarterly event.
Pages 1, 2, and 3 of the laboratory report for the June 1997 Monthly Progress and O&M
Report are attached to this letter.

I 5. Response: A copy of the June I 997 chain-of-custody record is attached to this letter.
16. Response: 0(1 June 30, 1997, the MDSG O&M contractor, Handex of the Carolinas,
Inc. (Handex) received a1telephone notice from the Macon System that there was a system fault.
When Handex personnel 1arrived at the site on July 2, 1997, they corrected the fault, started the
system, collected the mo11thly effluent sample, and proceeded with their routine monthly O&M
tasks at other locations of the Macon Dockery site. When the Hand ex crew returned to the '
Macon System later in the afternoon of July 2, 1997, the remedial system was again not operating.
I
After several attempts the remedial system could not be re-started because a transfer pump had
failed. The transfer pump was removed and sent to the manufacturer. On July 18, 1997, the
system was restarted.

I. Response: Acknowledged. In the future, duplicate samples will carry no identifiable
location data on the chain-of-custody record.
2. Response: Increased sample detection limits to levels above some of the performance
standards results from diluting samples at the laboratory. The dilutions are necessary for
parameters that are "above range" of the laboratory quantitative equipment. Many of the target
parameters are analyzed at the same time using the same method. Subsequently, the presence of a

22. Response: The soil vapor extraction (SVE) data reported in the Annual Summary
Report for February 22, 1996, are correct. The S VE data reported in the Monthly Progress and
' O&M report for April, 1996, are incorrect.
23. Response: · The VE-1001, VE-1002, VE-1003, VE-1004 SVE sample locations are
VE-01, OW-I, OW-2, and OW-3 sample locations, respectively. ·
Table 7 -Summary of Mass VOC Removal Estimates
!
24. Response: Table 7 has been corrected to reflect the revised Flow Volumes mentioned
in comment #I. Mass V0e removal calculations are based on influent voe analytical data and
system flow data. Since system influent samples are collected on a quarterly basis, the quarterly
analytical data is used for! calculating monthly mass removal estimates for the three months
following the quarterly sampling event. Total voe is taken as the sum of voe analytical data
that is reported by the lab1oratory to be above the sample detection limit. For the Upper/Lower
Macon systems, the Total voe concentration has been calculated as the sum of both system's
Total voes divided by two. A more accurate estimate of Total voes at the Upper/Lower
Macon site is to sum the Total voes from each system in the ratio of their respective flows.
AES has revised Table 7 to reflect this change. In addition, AES has undertaken a careful review
of the previous calculations paying particular attention to significant digits and rounding errors.
The revised Table 7 is attached to this letter.

the month and the cumulative is 1.36 pounds.
• Upper/Lower M~con flow meter reading for April totaled 918,080 gallons. Combined system
was operational 100% of the time averaging 22.76 GPM. Mass VOC removal was 0.18
pounds for the month and the cumulative is I. 89 pounds.
TASKS PLANNED FOR MAY 1997:
•
♦
♦
•
•
Monthly sampling of the remediation systems effluent.
Quarterly sampling of designated monitoring wells and system influents.
Quarterly air sampling ofSVE influents, system effluents, and the ambient air at the property·
line. ·
Continue O &M of systems .
Check Upper Dockery gallery. The gallery has been taking all of the effluent water and not
overflowing.
♦ Check Upper and Lower Macon infiltration gallery.
PROBLEMS AND DELAYS:
•
•
April 8, 1997 -Soil Vapor Extraction (SVE) system motor was removed because of excessive
noise and vibration. The motor has been diagnosed by the manufacturer as having failed
bearings. A reph\cement motor has been ordered.
April 18, 1997 -Upper Macon extraction well UM-6 was restarted following a drop of the
water level within the Macon infiltration gallery to a normal operating range.
. '
April 24, 1997 -Upper Macon Source Area extraction well UMS-4 was put placed back into
service after one ( 1) week off for repair of a motor saver.

Monthly Progr~ss and O & M Report -May 1997
Dear Ms. Bennett:
On behalf of the Macon/Dockery Site Group ("Group"), the May 1997 Monthly Progress and O &
M Report is herewith submitted in accordance with SECTION XV -PROGRESS REPORTS of the
Unilateral Administrative I Order ( effective date -June 30, 1992) for the Macon/Dockery Site. This
report describes activitie~ which occurred during the month of May as part of the Remedial Design
and Remedial Action pha,se of this project.
PROJECT TASKS INITIATED OR COMPLETED THROUGH May 1997:
i
• Quarterly sampling of the twelve monitor wells and remediation systems
• Continued O & M of systems .
RESULTS OF SAMPLING AND TESTING AND OTHER DATA RECEIVED:
•
•
•
Laboratory resultJ for May sampling of the remediation systems is included in this progress
report. Tables I to 4 summarize the analytical results for the four groundwater treatment
systems. All effluent concentrations are below the Remediation Performance Standard except
for the manganese concentration reported in the water sample collected from the Macon
Source Area system effluent port. According to the analytical report, the manganese
concentration for this sample was 95 ug/L. The Performance Standard for manganese is 50
ug/L.
Table 5 records the analytical results for the 12 monitor wells .

detection limit Air samples were not collected from the soil vapor extraction (SVE) system
because the SVE motor was being repaired at the time of the May sample activities. The
SVE air samples will be collected in the month of June.
Table 7 summarizes groundwater elevations recorded since system start up. Monitor wells
and recovery wells were gauged.
I
Upper Dockery flow meter reading for May totaled 289,938 gallons. System was operational
100% of the time averaging 5.44 gallons per minute (GPM). Mass VOC removal was 0.18
pounds for the month and the cumulative is 7.02 pounds.
Lower Dockery flow meter reading for May totaled 684,855 gallons. System was operational
100% of the time ~veraging 12.85 GPM. Mass VOC removal was 0.66 pounds for the month
and the cumulati✓e is 4. 15 pounds.
Macon Source Area flow meter reading for May totaled 223,177 gallons. System was
operational 100% of the time averaging 4.19 GPM. Mass VOC removal was 0.15 pounds
for the month and the cumulative is 1.51 pounds.
• . Upper/Lower Mason flow meter reading for May totaled 999,040 gallons. The Upper Macon
system was operational I 00% of the time in May. The Lower Macon system was operational
81% of the time :in May. The combined system flow averaged 18.75 GPM. Mass VOC
removal was 0.20, pounds for the month and the cumulative is 2.09 pounds.

Re: Macon/Dockery Site -Cordova, North Carolina
Monthly Progress and O & M Report -June 1997
Dear Ms. Bennett:
On behalf of the Macon/Dockery Site Group ("Group"), the June 1997 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 which occurred during the month of June as part of the Remedial Action
phase ·of this project.
PROJECT TASKS INITIATED OR COMPLETED THROUGH JUNE 1997: . '
• Quarterly sampling of the twelve monitor wells and remediation systems
'
• Continued O & M of systems.
RESULTS OF SAMPLING AND TESTING AND OTHER DATA RECEIVED:
•
•
Laboratory results for June sampling of the remediation systems is included in this progress
report. Tables I to 4 summarize the analytical results for the four groundwater treatment
systems. All eflluent concentrations are below the Remediation Performance Standard except
for the manganese concentration reported in the water sample collected from the Macon
Source Area system eflluent port. According to the analyt,ical report, the manganese
concentration for this sample was 74 ug/L. The Performance Standard for manganese is 50
ug/L. ,
Air samples were collected from the SVE remedial system to satisfy the May 1997, quarterly
sampling requirements. The air samples were not collected in May because the SVE system
was down during the May quarterly sampling event. A summary of the air sample analyses
' is contained on Table 6. The air samples collected from the SVE remediation system in June

were reported by the laboratory as below the detection limit.
Upper Dockery flow meter reading for June totaled 135,575 gallons. System was operational
' 100% of the time averaging 3.14 gallons per minute (GPM). Mass VOC removal was 0.08
pounds for the month and the cumulative is 7. I pounds.
Lower Dockery flow meter reading for June totaled 581,987 gallons. System was operational
' 100% of the time averaging 11.62 GPM. Mass VOC removal was 0.48 pounds for the month
and the cumulative is 4. 63 pounds.
Macon Source Area flow meter reading for June totaled 234,669 gallons. System was
operational 100% of the time averaging 5.43 GPM. Mass VOC removal was 0. 16 pounds
for the month and the cumulative is 1.67 pounds.
• Upper/Lower Macon flow meter reading for June totaled 605,792:gallons. The Upper Macon
system was operational 87% of the time in June. The Lower Macon system was operational
' 73% of the time in May. The combined system flow averaged 14.02 GPM. Mass VOC
removal was 0.12 pounds for the month and the cumulative is 2.21 pounds.
TASKS PLANNED FOR .JULY 1997:
•
•
Monthly sampling of the remediation systems eflluent
Continue O &M of systems
PROBLEMS AND DELAYS:
• June 2 to June 6 -Lower Macon System was down because of a low water level alarm in the
equalization tank. On June 6, 1997 the low level probe was adjusted to allow for greater
fluctuations in the tank and the system was restarted. '
• June 19 to June 20 -Lower Macon System was down because1oflow water level alarm in

' equalization tank. A cracked coupling was observed on the effluent pipe between the transfer
pump and the metals treatment units. The coupling was replaced and the system was
restarted on June 20, 1997.
June 24, to June 27, 1997 -The lower Macon system was down due to a low level alarm
condition in the equalization tank. The system was restarted on June 27, 1997. The reason
for the low level condition is being evaluated.
June 27, to June 30, 1997 -The Upper Macon system was down due to an electrical control
problem with the recirculation pump. The problem was not corrected before the end of the
reporting period. The recirculation pump electrical problem was repaired on July 7, 1997,
and the system was restarted.

•
Monthly sampling of the water effluent from the remediation systems
Continued O & M of systems .
RESULTS OF SAMPLING AND TESTING AND OTHER DATA RECEIVED;
• Laboratory results for July sampling of the remediation systems is included in this progress
report. Tables I to 4 summarize the analytical results for the four groundwater treatment
systems. The reported effluent concentrations are below the remediation performance
standard except for manganese in the effluent water sample collected July 2, 1997 from the
Upper/Lower Macon remedial system. The reported manganese concentration in this sample
was 79 ug/L. The manganese performance standard is 50 ug/L. The Upper/Lower Macon
system was resampled on July 25, 1997 to confirm the July 2, 1997 analytical results. The
July 25, 1997 samples were reported by the laboratory to have a manganese concentration
of 36 ug/L, which is below the performance standard.

The SVE blower motor was replaced in September 1996 due to water damage. In April
1997 the SVE blower motor was replaced with a motor designed for outdoor exposed
conditions.
Since start-up the SVE moisture separator tank frequently filled and shut down the SVE
system. In November 1996, the SVE moisture separator tank was automated to drain
once it had achieved a full status.
2.4 Effluent Concentrations
A measure of the system performance can be made based on the systems ability to
achieve remedial performance standards. A summary of the effluent water analytical
results is included in Table 3. During the reporting period the effluent sample analytical
results have been below the performance standard concentrations except for
manganese concentrations reported in effluent water samples collected from the Upper
Macon Source Area on July 30, 1996, September 4, 1996, and May 12, 1997. On
these dates the manganese concentrations were reported by the laboratory to be 11 O
ug/L, 68 ug/L, and 95 ug/L, respectively.
Based on the concentrations reported for the effluent water and air samples, the

June 3 - A severe thunderstorm caused an overload of most of the circuits. Fallen trees
blocked the entrances. Macon Source Area was down to overloads in the blower circuit
breaker. The system was restarted but the Foxboro flow meter had to be sent to the
manufacturer. Lower Dockery was down due to blower overloads. System was restarted and
is operating normally. Upper/Lower Macon was down due to the blower overlpads and
circuit breaker being tripped. The system was restarted and appears to be operating normally.
June 18 -Timer installed on SVE system and operational. Low water probe at Upper/Lower
Macon was fixed and operational.
