Many of the problems were associated with warrantied equipment and system
debugging as the site experienced its first year of operation.
2.1 Flow Rates and Totals
System flow total data are recorded on a weekly basis from the remedial systems.
Monthly totals for the systems are summarized in the monthly status reports. A
summary of the flow rates and totals for each groundwater system are included in Table
1. Since start-up in February 1996, the system flow totals are as follows:

♦ Lower Dockery 76 percent
♦ Macon Source Area 92 percent
♦ Upper Macon 82 percent
♦ Lower Macon 78 percent
♦ Soil Vapor Extraction System 82 percent
2.3 Problems Encountered and Corrective Actions
Several site-wide problems occurred during the reporting period that negatively affected
operational percentages for all of the remedial systems at the Macon/Dockery site. The
following sections describe those widespread problems followed by a description of
problems at individual sites.
2.3.1 Electrical Problems
During the spring and summer months of 1996, there were numerous power outages at
the project site due to non-project related power line work conducted offsite by the local
power company, Pee Dee Electric Company. On several occasions the power outages
required site visits after power was restored for manual restarting of the systems. After
August, 1996, the power line repair work conducted by Pee Dee Electric Company was
completed and the system disruptions due to this cause ceased to occur.

2.3.2 Weather Related Problems
In June 1996, all systems were down for four (4) days due to power disruption from a
storm. In August 1996, hurricane Fran passed through the area disrupting power to the
remedial systems for a period of up to three (3) weeks. In several locations, power was
interrupted due to tree branches falling on power lines onsite.
2.3.3 Individual Sites
The following sections briefly summarize problems and their corrective actions at the
individual Macon/Dockery remedial systems.
Upper Dockery
In June 1996, the Upper Dockery infiltration galleries were observed to be at
capacity when all of the groundwater extraction wells were in operation. During periods
when the infiltration galleries appeared to be at capacity; as many as two (2)
groundwater extraction wells were removed from service in an attempt to reduce the
flow entering the infiltration galleries. In July, 1996, the Upper Dockery infiltration
galleries were treated with chlorine. Since treatment, the infiltration galleries have been
performing within their design specifications.

Lower Dockery
Liquid level probes in the equalization tank failed repeatedly in June 1996 through
October 1996. In October 1996, the manufacturer replaced the defective probes.
Macon Source Area
The Macon Source Area remediation system has been performing without significant
problems since system start-up.
Upper Macon
Liquid level probes in the equalization tank failed repeatedly in June 1996 through
October 1996. In October 1996, the manufacturer replaced the defective probes.
On several occasions during the reporting period, the equalization tank has been
drained due to a suspected siphon effect. Vacuum breaks were added to the return
line in July 1996 to prevent siphoning effects.
In March 1997, the infiltration galleries that serve the combined flow from the Upper and
Lower Macon remediation systems were observed to be full. Two (2) Upper Macon
groundwater extraction wells were turned off for approximately three (3) weeks to
reduce the total flow to the infiltration galleries. After the three (3) week period, the two

(2) wells were returned to service and the infiltration galleries have been observed to be
operating within normal operating water levels. The infiltration gallery problem is
suspected to have been a seasonal problem.
Manganese treatment was added to the combined effluent of the Upper and Lower
Macon remediation systems in February 1997.
Lower Macon
Liquid level probes in the equalization tank failed repeatedly in June 1996 through
October 1996. In October 1996, the manufacturer replaced the defective probes.
On several occasions during the reporting period, the equalization tank has been
drained due to a suspected siphon effect. Vacuum breaks were added to the return
line in July 1996 to prevent siphoning effects.
Manganese treatment was added to the combined effluent of the Upper and Lower
Macon remediation systems in February 1997.
Soil Vapor Extraction System
Neighbors of the site complained about noise from the SVE blower in February, 1996.
As a result, the SVE blower was placed on a timer June 18, 1996, such that it operates

from 8:00 AM to 8:00 PM.
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.
Based on the concentrations reported for the effluent water and air samples, the
remediation systems are operating as originally designed.

3.0 System Effectiveness
System effectiveness at reducing contaminant concentrations at the site is indicated by
periodic groundwater elevation measurements and groundwater and air samples.
Groundwater elevation measurements and groundwater samples were collected from
the monitor wells on a quarterly basis during the period June 1, 1996, to June 1, 1997.
Air samples were collected from the groundwater system effluents and the SVE system
effluent and observation wells on a quarterly basis. The sampling frequency and
analytical parameters were conducted as stipulated in the Performance Standards
Verification Plan. On July 27, 1996, the EPA approved a reduction in the sampling
parameters and sampling frequency, based on analytical data trends observed for the
site by that date. A copy of the MDSG proposed sampling reduction and the EPA
response letter is contained in Appendix A.
A summary of the groundwater level measurements and calculated groundwater
elevations is contained in Table 4. Based on measurements conducted in monitor wells
(MW-11 and MW-21) located outside of the drawdown effect created by the
groundwater extraction wells; the background seasonal groundwater elevation appears
to have varied by approximately 7 to 9 feet during the reporting period.
A summary of the analytical results reported for the water samples collected from the
monitor wells is contained in Table 5. Air analytical results from the SVE system are

summarized in Table 6. Air sample results from the remediation system offgas sample
ports and from the property line sample are also summarized in Table 6.
Mass removal estimates are calculated for each of the remedial systems on a monthly
basis. The estimates are based on monthly flow volume and influent concentration
data. A summary of the mass removal estimates for the remedial systems is included
in Table 7.
Based on the mass removal estimates, the remediation systems at the Macon/Dockery
site are effectively remediating the subsurface target parameters.
4.0 1997/1998 Schedule
The following details the proposed 1997 /1998 schedule for the Macon/Dockery site
tasks:
♦ The 1997/1998 sample schedule is shown on Table 8;
♦ the approved operation and maintenance (O&M) program will continue;
♦ progress status reporting will continue to be submitted to the EPA on a monthly
basis; and,

Dear Mr, Gulledge:
This letter 1s written in response to your June 2 6, 199 6 latter in which you requeeted a reduction in laboratory sampling, and your June 27, 1996 letter in which you requested a change to the O & M Schedule,
The tiret request: to discontinue sampling for isophorone, mercury, and cyanide in the influent and effluent ey11te111s is approved. The request to discont:inue sampling tor isophorone illld cyanide in the monitoring wells is aleo approved. However, ae your letter etates, four wells will still be 4-I'lalyzed for mercury, Please be mindful that At the end of the remediation, all wells will be Blllllpled tor all eontaminar.te or concern and all muet be below the performance standards before remediation can be considered complete.
'l'he second regueet to reduce Lhe influent aampl ing tram monthly to quarterly is approved, however, the etfluent will still be eampled monthly.
The third regueet to eliminate the air etack samplin9 of the vario-us groundwater treatment systems is denied. Thou9h rural, the Site is still located in a reeidential neighborhood, and as such, human health is a concern. Therefore, sampling o! all air scaclts should occur on a quarterly basis. The SVE inlet can be eliminated, but the exhaust and the property line samples should be co:lected on a quarterly basis. Sampling o! the SVE wslla can be r@duced to twice a year.

The request to reduce the o & M site vie.itu from weekly to
monthly is denied and seems a bit premature. The June O & M report
etatss that the groundwater systems were only operational between
St and 33t. In addition, no mention is made in the report about
the succesis or failure ot adding the Clorox to the infiltration
galleries. Therefore, until the "bugs• are worked out, it would
seem prudent that the O & M visits continue on a weekly basis.
It'. you have any queecione, or would like to discuss this
rr.atter furt:her, please give me a call at 404/347-7791, ext 2065.

Re: Maconffiockery Site -Cordova, North Carolina
Request on Reduction in Laboratory Sampling
Dear Ms. Bennett:
Since system start up in early February 1996, the Macon/Dockery Site Group has coilected many
rounds of influent and effluent groundwater samples from the four remediation systems located at
the Macon/Dockery site. Our evaluation of the laboratory analytical data indicate a number of
analytical parameters that have consistently been below the Remediation Performance Standard or
below the detection limit. The analytical parameters are discussed below.
Isophorone, a semivolatile analyzed by EPA Method 8270 has been consistently repo11:ed to be
below the detection limit in all influent and effluent system samples and in the compliance monitor
wells. A review of the Final Remedial Design Repo11 by RMT had three wells sampled in March
1993 that detected isophorone from 3 J pg/L to 4 J µg/L. The Remediation Perfom1a.nce Standard
is 70 pg/L.
Mercury by EPA Method 7470 has been detected once at the Macon Source Area in the influent at
0.22 pg/L and once in the effluent at 0.26 pg/L. These concentrations are an order of magnitude
below the Remediation Performance Standard of 1.1 pg/L. The other system samples have
consistently been reported by the laboratory to be below the detection limit. Twelve monitor wells
are sampled quarterly. Only four of the wells have detected mercury, with two of the wells above
the Remediation Performance Standard.
Cyanide by EPA Method 9010 has consistently been reported below the detection limit in all of the
system samples but was detected once at 0.019 ,tg/L in a duplicate sample of monitor well MW-24.
The RMT data from March 1993 were below detection limit for cyanide. The Remediation
Performance Standard for cyanide is 154 pg/L.

The Macon/Dockery Site Group requests that EPA Methods 8270, 7470, and 9010 be discontinued
in the sampling of the influent and effluent systems at Macon/Dockery because of the consistent
below detection limits or detections below the Remediation Performance Standard. Also, EPA
Method 8270 should be discontinued in the compliance monitor wells since the analyte target
compound for these samples has been consistently reported by the laboratory to be below the
detection limit. Mercury by EPA Method 7470 should be reduced to just the four monitor wells
(MW13, MW15, MW19, and MW23) that have had detections. Cyanide by EPA 9010 should be
discontinued in the compliance monitor wells since there has been just one recorded detection and
it was orders of magnitude below the Remediation Performance Standard.
The influent data has been necessary on a monthly basis to evaluate the concentrations of the
analytes entering into the remediation systems, The concentrations detected have been fairly
consistent in the different sampling events. The Macon/Dockery Group requests that the sampling
frequency of the influent be reduced to quarterly. The effluent will continue to be sampled momhly.
The Monthly Progress and O & M Report for May 1996, documented the mass VOC removal based
on the analytical results from the influent and effluent concentrations. If these total VOCs were
passed through the air stripper, the total pounds released to the atmosphere would be below the air
discharge permit. RMT in the Operation an<l lvlaintenance Plan calculated the air stripper air
emission rates and a worst case air emission rate_s from the soil vapor extraction unit. All values
were below the 40 pounds of VOC emissions per day and below the thresholds for individual air
toxins.

The calculations of the worst case off gas from the discharge stacks and estimating the mass VOC
removal based on the influent and effluent concentrations in the groundwater, demonstrate that the
off gases are below the North Carolina air pollution rules. The Macon/Dockery Site Group requests
that the air stack sampling at Upper Dockery, Lower Dockery, Macon Source Area, and
Upper/Lower Macon be discontinued. VOC mass removal rates will continue to be estimated using
the reported concentration of influent and effluent groundwater samples and the measured flow rates.
The property line sample and SVE inlet are also recommended for elimination. The SVE exhaust
will be continued on a quarterly basis. It is recommended that air samples from the SVE wells be
collected twice per year.
We appreciate your consideration in this matter.
