IC Project No.: 0004-001
Dear Ms. Bennett:

SUPERFUND SECTION
On behalf of the Macon Dockery Site Group (MDSG), lrminger Consulting, Inc. (JC) is pleased to
submit this request for suspension of the Lower Macon groundwater remediation system at the
Macon Dockery NPL site located in Cordova, North Carolina. A portion of the United States
Geological Survey topographic map of the Laurinburg quadrangle showing the approximate
location of the site is attached to this letter as Figure I. A site map of the Lower Macon system is
provided as Figure 2.
Macon Dockery Site History
Remediation at the Macon Dockery site was initiated on February 22, 1996, with the start-up of a
Soil Vapor Extraction (SVE) system and four separate groundwater remediation systems. The
SVE system was installed in the area of former Lagoon 7 to remediate vadose zone soils beneath
the former lagoon. Remediation goals for soil beneath Lagoon 7 were met and the request for
closure of the SVE system was approved in a letter from the United States Environmental
Protection Agency (EPA) dated May 19, 2000. Abandonment of the SVE system began
December 27, 200 I, and was completed on April 26, 2002. Abandonment of the SVE system is
documented in the "Soil Vapor Extraction Abandonment Report" dated November 8, 2002.
A request to suspend operation of the Lower Dockery Remediation System was submitted to EPA
on February 11, 2004. The suspension request was based on a comparison of analytical data to
performance standards. The suspension request was approved by EPA and the remediation system
was turned off on March I 0, 2004.
Lower Macon Groundwater Remediation System
The Lower Macon remediation system is supplied with groundwater from five extraction wells
using jet pump technology. A 20-horsepower recirculation pump located at the remediation

system equipment compound circulates water to all five wells in a closed loop system. Smaller
pipes connected to the main loop are used to create a venturi through an eductor located down the
well. At the equipment compound, the water flows through two parallel bag filters then into the
feed tank. The bag filter assists with suspended solids and metals removal. A six-inch diameter
PVC pipe flows water by gravity from the feed tank to the low-profile air stripper. The air stripper
aerates the groundwater to promote the volatilization of volatile organic compounds (VOCs) and
their subsequent removal through the offgas stack of the air stripper. Other equipment
accompanying the air stripper include a blower, effluent sump, an inlet screen and damper, and a
steel demister. Treated water flows by gravity out of the effluent sump to two infiltration galleries
where it reenters the ground.
Lower Macon Remediation System Performance
Since start-up in 1996, the system has maintained an average annual operational percentage of
approximately 82% (as reported in the 2008 Annual Operation and Maintenance Report). The
production rate is not measured directly because the treated water from the Lower Macon system
is combined with the treated water from the Upper Macon system prior to the flow meter.
However, the combined systems have treated over I I 0,000,000 gallons of water since start-up.
No modifications have been made to the system since 1996. System downtime is attributed to
repair work as the result of malfunctioning pumps, power interruption, freeze damage, blower
malfunctions, and high sump water level alarms in the air stripper.
Lower Macon Remediation System Effectiveness
Lower Macon system influent and effluent samples were collected weekly for the first month of
system operation and monthly thereafter for the first year. In 1997, the MDSG was allowed to
begin quarterly system influent and effluent sampling. In June 2000, the MDSG was granted
permission to begin semi-annual sampling of system influents, but was still required to conduct
quarterly system effluent sampling. Lower Macon groundwater remediation system influent and
effluent samples are presently collected semi-annually and quarterly, respectively.
A review of historical laboratory analytical results for the Lower Macon system influent samples
indicates that since January 28, 2006, all organic and inorganic parameter concentrations have
consistently been below the Performance Standards specified in the "Performance Standards
Verification Plan" dated October I 994. A summary of the influent sample results is included in
Table 1, which is attached to this letter.
Groundwater samples for the Lower Macon site are collected from groundwater monitoring wells
MW-13 and MW-22. A review of historical laboratory analytical results for groundwater samples
collected from well MW-22 indicate that concentrations of VOCs have not exceeded the
Performance Standards since July 30, 2002, when 1,1-dichloroethene was reported in the
groundwater sample at a concentration of 7 .3 ug/L, which is greater than the performance standard
of7.0 ug/L. A review of the historical data from well MW-22 indicates that inorganic parameters
have been below performance standards since January 28, 2005, when manganese was reported in
the groundwater sample at a concentration of 290 ug/L which is greater than the performance
standard of 50 ug/L.

A review of historical laboratory analytical results for groundwater samples collected from well MW-13 indicates that concentrations ofVOCs have not exceeded the Performance Standards since 1998. A review of the historical data from well MW-13 indicates that manganese concentrations remain above the performance standard of 50 ug/L. In August 2008, a groundwater sample collected from well MW-13 was reported with a manganese concentration of 450 ug/L. Beryllium was reported in the groundwater sample collected in August 2008 at a concentration of 1.9 ug/L, which is greater than the performance standard for beryllium of 1.0 ug/L. Other inorganic parameters have been below performance standards since August 19, 2006, when lead and vanadium were reported in the groundwater sample at a concentration of 27 ug/L and 99 ug/L, respectively. The performance standards for lead and vanadium are 15 ug/L, and 50 ug/L, respectively. A chronological summary of the analytical groundwater sample results is provided in Table 2 which is attached to this letter.
Background Concentrations
Inorganic concentrations greater than the Performance standard reported in groundwater samples collected from well MW-13 are consistent with background concentrations reported in the North Carolina Geological Survey (NCGS) Open-File Report 93-19 dated July 1993. This report lists the concentrations of nine inorganic parameters reported in 23 groundwater samples collected in Richmond County. The NCGS report reports analytical results in units of parts per billion which are approximately equivalent to micrograms per Liter. Manganese was reported in 21 of the 23 groundwater samples. The Manganese concentrations ranged from a high of 867 parts per billion (ppb) to a low of 6 ppb. The average of the 21 results is IO I ppb. The manganese concentrations reported by the NCGS in Richmond County are consistent with the concentrations observed in the Lower Macon monitoring wells, which supports the conclusion that the manganese concentrations are naturally occurring background concentration. The NCGS report did not analyze groundwater samples for lead, vanadium, or beryllium. Excerpts of the report are contained in Attachment I.
The 1993 NCGS Open-File Report 93-19 reported the results of stream sediment samples collected in Richmond County and analyzed for numerous inorganic parameters. Twenty-seven sediment samples were analyzed for manganese and vanadium. The manganese results ranged from a high of 670 parts per million (ppm) to a low of 20 ppm with an average concentration of 126 ppm. The vanadium results ranged from a high concentration of l00 ppm to a low of lO ppm with an average concentration of 30 ppm. Twenty-eight sediment samples were analyzed for beryllium and lead. The beryllium results ranged from a high of 2.5 parts per million (ppm) to a low of less than the detection limit of 0.5 ppm. Thirteen of the sediment samples were reported to be less than the detection limit of 0.5 ppm for beryllium. Of the remaining 15 sediment samples, the average beryllium concentration reported was 0.8 ppm. The lead results ranged from a high concentration of 27 ppm to a low of less than the detection limit of IO ppm. Sixteen of the sediment samples were reported to be less than the detection limit of IO ppm for lead. Of the remaining 12 sediment samples, the average lead concentration reported was 14 ppm. While sediment sample analytical concentrations cannot be compared directly to groundwater concentrations, the presence of these parameters above the detection limit support the conclusion that their low concentrations at the site are naturally occurring and representative of background conditions.
In I 999, the NCGS used the 1993 stream sediment sample data to create geochemistry maps which indicate naturally occurring concentrations of inorganics in stream sediment samples

collected in the site area. Copies of the NCGS geochemistry maps of manganese, vanadium, and
lead concentrations in stream sediment for the piedmont of North Carolina are provided in
Attachment 2.
Effect of Suspended Solids
Irminger Consulting, Inc. prepared comparison charts, which reveal trends associated with
concentrations of inorganics and suspended solids. The charts are provided in Attachment 3.
The charts indicate that high concentrations of suspended solids correlate with high concentrations
of inorganics. This data demonstrates that high concentrations of inorganic compounds are
associated with high suspended sediment, and are not dissolved at these concentrations.
Conclusion
Sufficient technical justification to warrant the suspension of the Lower Macon groundwater pump
and treat system is summarized in the list below.
• VOC concentrations have not exceeded the Performance Standards since 2002 in well
MW-22 and 1998 in well MW-13;
• Inorganic concentrations in well MW-22 have not exceeded the Performance Standards
since January 2005;
• Inorganic concentrations in wells MW-13 and MW-22 are consistent with naturally
occurring concentrations reported by the North Carolina Geological Society;
• Laboratory analytical results and comparison charts demonstrate a correlation between
high concentrations of suspended sediment and high concentrations of inorganics in wells
MW-13 and MW-22. This data indicates that the inorganics are not dissolved in the
groundwater at these concentrations; and,
• Influent concentrations to the remediation system have been below the Performance
Standards for all parameters, organic and inorganic, for three years, since January 2006.
Based on the justification listed above, the MDSG requests authorization from EPA to turn off the
Lower Macon remedial equipment. lrminger Consulting and the MDSG appreciate your
assistance on this matter. Should you have any questions, please contact us at [phone].
