Re: Macon/Dockery Site -Cordova, North Carolina
Request for Modification to Well Sampling Frequency
Dear Ms. Bennett:
In accordance with the second Five Year Review prepared by the United States Environmental
Protection Agency (EPA) and North Carolina Department of Environment and Natural Resources
(DENR), the Macon Dockery Site Group (MDSG) is requesting a reduction in the frequency of
performance monitoring groundwater samples collected from monitoring wells.
Groundwater from monitoring wells at the Macon Dockery Superfund Site is cun-ently sampled on a
semi-annual basis. A summary table of historical analytical results is attached to this letter as Table
I. A review of the tabulated data demonstrates that the dissolved concentrations have reached stable
or discernable trends. For these reasons, the MDSG requests that the monitoring well sampling
frequency be reduced to once per year.
The cun-ent semi-annual pe,formance monitoring sample schedule includes well sampling in January
and July. The MDSG requests that the January 2006 well sampling event be cancelled. The next
well sampling event will be in July 2006. Subsequent well sampling events will occur in July of
each subsequent year. A proposed revised sample schedule is attached to this letter as Table 2.
The MDSG appreciates the EPAs' consideration of the request documented above. Should you have
any questions regarding these requests, please do not hesitate to contact me at [phone].

1.0 Introduction
The Macon/Dockery Site is located approximately 1.6 miles southwest of Cordova, North
Carolina in Richmond County, North Carolina. The site is bounded to the east by state road (SR)
1103 and to the north, west, and south by woods and farmland. The site is officially described as
comprising a 16-acre tract owned by relatives and heirs of Charles Macon, and a one-acre tract
owned by John Dockery. The Dockery property is located approximately 2,600 feet north of the
Macon property and is non-contiguous with it. The Macon property is approximately 60 percent
wooded while the Dockery property is almost entirely wooded. Current land use in the vicinity
of the site is primarily agricultural with limited residential use along SRI 103. Figure I is a site
location map that shows the locations of the Macon and Dockery properties.
I.I Background
Prior to the mid-l 970s, the Macon property was maintained as undeveloped woodlands
and pasture. From the late 1970s until 1980, Charles Macon operated a waste disposal and oil
recycling business on the Macon property. Materials such as antifreeze, used waste oil, metals,
paint, solvent wastes, waste acid, and bases were handled and stored on site. During operation of
the facility, some of the materials were disposed in unlined lagoons and leaking drums, resulting
in the release of hazardous substances including polyaromatic hydrocarbons (PAHs), metals, and
solvents. C&M Oil Distributors leased and operated the oil recycling facility on the Macon
property from 1981 to 1982. During the time that he operated the Macon property as an oil
recycling facility, Charles Macon also utilized the Dockery property for conducting certain
portions of his business.
On November 11, 1983, EPA initiated a removal action on the Macon Property.
Removal operations on the Dockery Property began on January 9, 1984. Removal activities at
both properties were completed on January 17, 1984. During the course of the removal action,
EPA removed contaminated soils and materials (including over 2,000 drums of hazardous
Page No. I
•
substances) from the entire site. Some hazardous substances were contained on-site until the
initiation of remedial action.
In 1985, EPA conducted a geological and sampling investigation at the Site. The
'
investigation detected the presence of hazardous substances in groundwater and soil. In January
1987, the Site was proposed for inclusion on the National Priorities List (NPL), and in July 1987,
pursuant to Section I 05 of CERCLA, EPA placed the Site on the NPL. As a result of the
proposed inclusion of the Site on the NPL, Sirrine Environmental Consultants initiated a
Remedial Investigation/Feasibility Study (RI/FS) for the site on April 13, 1988. The Remedial
Investigation (RI) Report was completed in February I 991, and the Feasibility Study (FS) Report
was completed in July I 991.
Based on the findings of the RI, Performance Standards were established for 26
substances. The groundwater Remediation Performance Standards are attached as Table I.
Sampling in all media confirmed that groundwater beneath and hydraulically downgradient of
the source areas and soil in two former lagoons contained substances above the Perfonnance
Standards. Groundwater was found to be moving in a northwesterly direction.
On September 30, 1991, US EPA issued a Record of Decision (ROD) for the
Macon/Dockery Site. The ROD was reissued on April 12, 1992. The ROD set forth the US
EPA' s rationale and the remedy selected to address remaining vessels, and affected soils and
groundwater identified at the site. US EPA issued a Unilateral Administrative Order (UAO) and
Statement of Work for Remedial Design and Remedial Action. The effective date of the UAO
was June 30, 1992. The Statement of Work (SOW) lists the requirements for implementing the
remedy as described in the ROD and for achieving Performance Standards set forth in the ROD.
US EPA specified the following remedial actions and work elements for the Macon/Dockery
Site:
Groundwater Control: Groundwater with concentrations of constituents of concern
Page No. 2
• •
greater than the Performance Standards specified in the SOW must be extracted, treated on-site
via air stripping, and discharged to an infiltration gallery.
Source Control: Contaminated soils at Lagoon 7 and Lagoon 10 and related
materials must be addressed. Vadose Zone soils underlying Lagoon 7 must be treated via soil
vapor extraction (SVE) to remove tetrachloroethene (PCE) to levels below the Performance
Standard of 3 parts per million (ppm). The ROD and SOW required that a bioremediation
treatability evaluation of waste materials from lagoon IO be performed using indigenous
microbial populations to degrade carcinogenic poly nuclear aromatic hydrocarbon (P AH)
compounds to a Performance Standard of 2 ppm total P AHs. The treatability study for
bioremediation of Lagoon 10 waste was conducted and a report was included in the Preliminary
Design Report. Based on treatability study results and additional information regarding the
nature of the waste obtained from a resampling effort, the US EPA amended the ROD in March
1994 to provide for excavation and off-site disposal of Lagoon 10 materials.
Vessel Removal: Hazardous materials remaining in tanks and vats at the site must be
transported to an appropriate off-site facility for proper disposal. Non-hazardous vessel contents
will be recycled or transported off-site for proper disposal. The vessels will be recycled or
decommissioned. If evidence of leakage is noted after the vessels are removed, the remedial
action will also include cleanup of affected surficial soils.
A Final Remedial Design Report for SVE operations was submitted on June 14, 1994.
The groundwater remedy design was separated from the SVE design to allow the Macon
Dockery Site Group (MDSG) to conduct studies of the applicability ofbioremediating volatile
organic constituents on source area groundwater. Currently, one SVE system and four
groundwater pump and treat systems are in operation at the site.
The MDSG undertook the waste removal phase of the Remedial Action beginning in June
1994. The waste removal phase included removal of Lagoon 10 wastes, various process and
Page No. 3
•
storage vessels associated with previous operations, and wastes generated during previous
investigation activities. Waste removal activities were completed in November 1994.
2.0 Purpose
The purpose of this Sampling and Analysis Plan (SAP) is to document soil conditions in
the area of former Lagoon 7 of the Macon Dockery Superfund site. The SAP provides
descriptions and details of the proposed procedures for soil verification sampling and subsequent
regulatory reporting. Since the installation of the SVE unit at Lagoon 7, SVE exhaust and
extraction well point air samples have been collected on a quarterly and semi-annual basis
respectively. A review of recent and historical air sample data from samples collected in relation
to the SVE system have consistently been below the air emissions Performance Standards
established for the site. The following SAP provides details and descriptions of the proposed
procedures for assessing the subsurface soils in the area of former Lagoon 7. The goal of the
proposed soil assessment in the area of former Lagoon 7 is to determine if SVE operations have
reduced COC concentrations to below the Performance Standards for the site.
3.0 Soil Vapor Extraction System
The SVE system installed in the area of former Lagoon 7 was installed to remediate
vadose zone soils beneath the former lagoon. The SVE system consists of a series of SVE wells
used for vacuum extraction and soil venting. Remediation at Lagoon 7 initiated on February 22,
1996, by soil vapor extraction (SVE). Since system start-up, the system has operated a large
vacuum unit that induces vacuum on SVE wells VE-I, OW-I, OW-3, and OW-5 to recover soil
vapors. Vapors captured by the SVE system are discharged to the atmosphere through a v~rtical
discharge stack. Ambient air enters the vadose through the ground surface and through two soil
venting wells (OW-2 and OW-4). Figure 2 details the layout of the SVE system and associated
SVE wells.
The SVE system has extracted vapors from wells VE-I, OW-I, OW-3, and OW-5 since
start-up. Air samples have been collected from extraction well points and the exhaust side of the
Page No. 4
• •
SVE system on a quarterly, and semi-annual basis, respectively. Air samples collected in
association with the SVE system are analyzed for volatile organic compounds (VOCs) by EPA
Method 18. A review of the historical SVE system effluent results indicates that air samples
collected from the individual SVE points and the SVE exhaust stack have been below the
laboratory detection limits for volatile organic compounds (VOCs) since November 1997. For
this reason, the Macon Dockery Site Group (MDSG) believes that there is sufficient technical
justification to warrant the closure of the SVE system. A summary of the analytical results
associated with the SVE system are attached as Table 2.
4.0 Sample Collection Procedure
As detailed in Section 3.1.8 of the Performance Standards Verification Plan (PSVP) dated
July 11, 1994, AES proposes to collect soil samples from four soil borings advanced within the
perimeter of former Lagoon 7. The soil borings will be located on two perpendicular axes of
Lagoon 7. Section 3.1.6 of the PSVP states that the confirmatory soil borings will be located on
two perpendicular axes of Lagoon 7 and approximately 20 feet on either side of the lagoon
center. However, should soil borings on the east/west axis be advanced approximately 20 feet
on either side of the lagoon center, the soil borings would be located outside of the former lagoon
boundary. The soil borings located on the east/west axis will be located approximately 10 feet
on either side of the lagoon center and soil borings located on the north/south axis will be located
approximately 20 feet on either side of the lagoon center. Figure 3 shows the locations of the
proposed confirmation soil borings.
The soil borings will be advanced using continuous flight hollow stem auger with a split
spoon sampler used to collect the subsurface soil san1ples for the verification sampling. As
stated in the PSVP, confirmatory soil samples will be collected at the 22 to 24-foot depth interval
and the 29 to 31-foot depth interval from each of the four soil borings. However, Section 2,
paragraph 2 of the Final Remediation Design Report for the SVE System states that "during the
RI, PCE was detected at a concentration of 31 mg/kg at the 25 to 27 foot depth in soil boring SB-
Page No. 5
•
7, which is located in former Lagoon 7." To account for this discrepancy and assure that this
interval is assessed during the soil confirmation sampling, the MDSG proposes to collect
continuous split spoon soil samples beginning at 20 feet below grade level (BGL) and
terminating at 32 feet BGL.
All drilling and sampling activities associated with the confirmatory sampling will be
conducted under the direction of a professional geologist or professional engineer registered in
the state of North Carolina. The soil borings will be installed by advancing hollow stem augers to
32 feet below grade. Undisturbed soil samples will be collected using a stainless steel split
spoon san1pler advanced in two-foot intervals through the augers. The split spoon sampler will
retrieve soil samples from the following depth intervals below grade: 10-12 feet: 15-17 feet: 20-
22 feet: 22-24 feet: 24-26 feet: 26-28 feet: 28-30 feet: and 30-32 feet.
Soil cuttings and soil recovered in the split spoon samplers will be described with a
lithologic description. In addition, soil cuttings and soil recovered in the split spoon samplers
will be field screened by headspace analysis. The collected soil samples will be placed into
plastic air-tight bags and screened with an organic vapor analyzer equipped with a
photoionization detector (PIO).
Soil samples collected for laboratory analysis will be collected from the split spoons
advanced at the 22 to 24-foot interval and the 28 to 30-foot interval. In addition, one soil sample
will be collected for laboratory analysis from the interval exhibiting the highest PIO reading. If
there are no PIO readings above the detection limit, or the highest reading occurs in the 22 to 24-
foot or 28 to 30-foot depth intervals; only two (2) samples will be collected from the boring for
laboratory analysis. All drilling and sampling activities will be conducted in accordance with the
PSVP for the Macon/Dockery Site and the US EPA Region IV Environmental Investigations
Standard Operating Procedures and Quality Assurance Manual.
Drilling equipment will be decontaminated according to the procedures outlined in
Page No. 6
•
.
Section 4.0 of this report. Decontamination procedures will occur between each boring in the
designated decontamination area. The downhole equipment will not be allowed to come into
contact with potentially contaminated materials until boring operations commence.
Following completion of each boring, the borings will be abandoned with a
water/cement/bentonite mixture with a ratio of approximately 3 :6: I. Soil cuttings generated by
the installation of the borings will be placed into 55-gallon drums and stored in a designated
storage area on-site.
5.0 Sample Analysis
Each soil sample collected for laboratory analysis will be placed into a four ounce,
laboratory supplied, glass sample jar equipped with a Teflon lid. For the purposes of the soil
confirmation sampling, the chain-of-custody procedures outlined in Section 4-1 of RMT' s Field
Sampling and Analysis Plan dated June 1994 will be followed. By the use of chain-of-custody
procedures, the handling of samples will be traceable from the time of sample collection to the
time of final disposition. Field personnel will record the sample number, date and time of
sample collection, personnel involved, type of sample, type of analysis to be performed, type of
containers filled, volume of sample collected, and preservatives used. Field measurements such
as sample depth, location, and PIO reading will be recorded in the sample personnel's field notes.
Soil samples collected for analysis will be placed into a cooler pre-packed with ice. A
temperature blank inside of the pre-packed cooler will be used to assure that the samples
maintain a temperature of no greater than 4-degrees Celsius (C). Prior to shipment, the cooler
will be sealed with adhesive custody seals to assure that the samples are not disturbed during
shipment. Soil samples will be shipped, via overnight delivery, to STL Savannah Laboratories,
Inc. (STL), a North Carolina Certified Laboratory, in Savannah, Georgia. The MDSG will
request that the soil samples be analyzed for VOCs by EPA Method 8260, with a method
Page No. 7
•
quantitation limit no greater than 0.5 mg/kg. STL will extract the soil samples prior to the
expiration of the 14-day hold time.
6.0 Decontamination/Health and Safety Procedures
Large drilling apparatus including drill augers, bits, and the back of the drill rig, will be
steam cleaned prior to beginning boring operations and again in between each boring. Soil
sampling equipment, including split spoon samplers, will be decontaminated before sampling
and between the collection of each sample. Soil sampling equipment will be decontaminated in
accordance with the US EPA's Region IV Environmental Investigations Standard Operating
Procedures and Quality Assurance Manual and Section 1 1.0 of the Site Health and Safety Plan
for the Macon/Dockery Site. Soil sampling equipment will be decontaminated using the seven-
step decontamination procedure listed below.
1. Scrub brushed using clean tap water and laboratory detergent.
2. Tap water rinse.
3. Deionized organic-free water rinse.
4. Isopropanol rinse.
5. Deionized organic-free water rinse.
6. Air dry
7. Equipment will be wrapped with plastic or aluminum foil to minimize the
possibility of contamination.
Decontamination procedures will be performed on a decontamination pad designed to
collect all liquid and particulate matter resulting from such procedures. The decontamination pad
will be constructed on the existing concrete pad (formerly used as a decontamination pad) near
the Macon Source Area groundwater pump and treat system. The decontamination pad will be
12-foot by 12-foot in size and constructed of 6 mil (0.006) thick plastic inside of four inch by
four inch rails. All decontamination procedures will be conducted on the decontan1ination pad.
Page No. 8
• •
The decontamination pad plastic, liquid, and particulate matter accumulated from the
decontamination procedures will be placed into 55-gallon drums and stored on-site.
All drilling and sampling activities occurring at the site will be conducted in accordance
with the Site Health and Safety Plan prepared for the Macon/Dockery Site by Handex of,the
Carolinas dated June 1995. Drilling and sampling personnel will be equipped with Level D
personal protective equipment including latex gloves, Tyvek suits, hard hats, steel toed safety
boots, and safety glasses. Disposable personnel protective gear (i.e. gloves, Tyvek suits) will be
placed into 55-gallon drums and stored on-site. Provisions will be available onsite for upgrade to
Level C personal protection equipment should conditions warrant.
7.0 Disposal of Drummed Materials
If analysis of the sampled intervals indicate that the PCE concentration in soil is less than
3.0 mg/kg, the Performance Standard for PCE at the Site, then the drummed soil cuttings will be
spread onsite and the used Tyvek and other disposable san1pling materials will be disposed in a
secure landfill in accordance with Federal, State, and local regulations. Should the analyses
indicate PCE concentrations greater than 3.0 mg/kg, then the drummed soil and sampling
materials will be transported and disposed at an appropriately licensed facility. In the event that
compounds other than PCE are detected in the soil samples, the US EPA and NCDENR will be
consulted in order to determine the appropriate method of disposal for the drummed soil cuttings.
Collected rinse water will be slowly combined with the influent water of the Macon Dockery
Source Area groundwater treatment system. The rinse water will be discharged into the
remediation system at a point prior to the sediment filters in order to avoid potential problems
from the presence of naturally occurring metals or from sediment deposition itself.
8.0 Reporting
Following receipt of the laboratory analytical results, a report of the results will be
Page No. 9
•
presented to the US EPA, NCDENR, and MDSG members. The report will include all data
collected during the soil sampling event such as field notes, lithologic descriptions, headspace
analytical results, and laboratory analytical data. The data will be presented in a Completion
Report and will include all associated text, tables, and site figures. The report will also
recommend a future course of action at former Lagoon 7.
Drilling activities and the associated laboratory analytical results will result in one of four
scenarios. The following section describes the four scenarios and their potential outcomes:
1. PCE meets the Performance Standard and no additional compounds are detected.
2. PCE meets the performance standard and additional compounds are detected.
3. PCE does not meet the Performance Standard and no additional compounds are
detected.
4. PCE does not meet the Performance Standard and additional compounds are
detected.
Scenario I provides evidence that the SVE Performance Standards have been met, that all
SVE operations are complete and that the SVE system may be turned off. Scenario 3 and
Scenario 4 provide evidence that the SVE Performance Standards have not been met, that
operation of the SVE remediation system must continue, and that the MDSG shall submit a
report suggesting strategic modifications to the SVE system such that contaminant
concentrations are removed from the subsurface more efficiently. Scenario 2 and Scenario 4
present the problem of additional contaminants present at the site. In the event this situation
arises, the MDSG will consult with the US EPA and NCDENR in order to determine the
appropriate performance standard for each contaminant detected. In the event that the levels of
each of the detected contaminants are below their respective Performance Standard, operation of
the SVE system may be considered complete and SVE operations discontinued. However, in the
event that the levels of each of the detected contaminants are not below their respective
Performance Standard, operation of the SVE system may not be considered complete and SVE

operations must continue. Additionally, the MDSG shall submit a report suggesting strategic
modifications to the SVE system such that contaminant concentrations are removed from the
subsurface more efficiently.
In the event that the remediation is not complete and the SVE process cannot be modified
to address the contamination, the MDSG will submit an alternate remediation strategy for
Lagoon 7.
9.0 Schedule
Upon approval of the Sampling and Analysis Plan, the MDSG anticipates completing the
work in accordance with the Schedule presented in Figure 4 of this report.

1.0 Introduction
The Macon/Dockery Site is located approximately 1.6 miles southwest of Cordova, North
Carolina in Richmond County, North Carolina. The site is bounded to the east by state road (SR)
1103 and to the north, west, and south by woods and farmland. The site is officially described as
comprising a I 6-acre tract owned by relatives and heirs of Charles Macon, and a one-acre tract
owned by John Dockery. The Dockery property is located approximately 2,600 feet north of the
Macon property and is non-contiguous with it. The Macon property is approximately 60 percent
wooded while the Dockery property is almost entirely wooded. Current land use in the vicinity
of the site is primarily agricultural with limited residential use along SR 1103. Figure 1 is a site
location map that shows the locations of the Macon and Dockery properties.
1.1 Background
Prior to the mid-l 970s, the Macon property was maintained as undeveloped woodlands
and pasture. From the late 1970s until I 980, Charles Macon operated a waste disposal and. oil
recycling business on the Macon property. Materials such as antifreeze, used waste oil, metals,
paint, solvent wastes, waste acid, and bases were handled and stored on site. During operation of
the facility, some of the materials were disposed ofin unlined lagoons and leaking drums,
resulting in the release of hazardous substances including polyaromatic hydrocarbons (PAI-Is),
'
metals, and solvents. C&M Oil Distributors leased and operated the oil recycling facility on the
Macon property from 1981 to 1982. During the time that he operated the Macon property as an
oil recycling facility, Charles Macon also utilized the Dockery property for conducting certain
portions of his business.
On November 11, I 983, EPA initiated a removal action on the Macon Property.
Removal operations on the Dockery Property began on January 9, 1984. Removal activities at
both properties were completed on January 17, 1984. During the course of the removal action,
EPA removed contaminated soils and materials (including over 2,000 drums of hazardous
Page No. I
•
substances) from the entire site. Some hazardous substances were contained on-site until the
initiation of remedial action.
In 1985, EPA conducted a geological and sampling investigation at the Site. The
investigation detected the presence of hazardous substances in groundwater and soil. In January
1987, the Site was proposed for inclusion on the National Priorities List (NPL), and in July 1987,
pursuant to Section 105 ofCERCLA, EPA placed the Site on the NPL. As a result of the
proposed inclusion of the Site on the NPL, Sirrine Environmental Consultants initiated a
Remedial Investigation/Feasibility Study (RI/FS) for the site on April 13, 1988. The Remedial I
Investigation (RI) Report was completed in February 1991, and the Feasibility Study (FS) Report
was completed in July 1991.
Based on the findings of the RI, Performance Standards were established for 33
substances. Sampling in all media confirmed that groundwater beneath and hydraulically
downgradient of the source areas and soil in two former lagoons contained substances above the
Performance Standards. Groundwater was found to be moving in a northwesterly direction.
On September 30, I 991, US EPA issued a Record of Decision for the Macon/Dockery
Site. The ROD was reissued on April 12, 1992. The ROD set forth the US EPA's rationale and
the remedy selected to address remaining vessels, and affected soils and groundwater identified
at the site. US EPA issued a Unilateral Administrative Order (UAO) and Statement of Work for
Remedial Design and Remedial Action. The effective date of the UAO was June 30, 1992. The
Statement of Work (SOW) lists the requirements for implementing the remedy as described in
the ROD and for achieving Performance Standards set forth in the ROD. US EPA specified the
following remedial actions and work elements for the Macon/Dockery Site:
Groundwater Control: Groundwater with concentrations of constituents of concern
greater than the Performance Standards specified in the SOW must be extracted, treated on-site
via air stripping, and discharged to an infiltration gallery.
Page No. 2
•
Source Control: Contaminated soils at Lagoon 7 and Lagoon IO and related
materials must be addressed. Vadose Zone soils underlying Lagoon 7 must be treated via soil
vapor extraction (SVE) to remove tetrachloroethene (PCE) to levels below the Performance
Standard of 3 parts per million (ppm). The ROD and SOW required that a bioremediation
treatability evaluation of waste materials from lagoon IO be performed using indigenous
microbial populations to degrade carcinogenic poly nuclear aromatic hydrocarbon (P AH)
compounds to a Performance Standard of 2 ppm total PAHs. The treatability study for
bioremediation of Lagoon IO waste was conducted and a report was included in the Preliminary
Design Report. Based on treatability study results and additional information regarding the
nature of the waste obtained from a resampling effort, the US EPA amended the ROD in March
1994 to provide for excavation and off-site disposal of Lagoon IO materials.
Vessel Removal: Hazardous materials remaining in tanks and vats at the site must be
transported to an appropriate off-site facility for proper disposal. Non-hazardous vessel contents
will be recycled or transported off-site for proper disposal. The vessels will be recycled or
decommissioned. If evidence of leakage is noted after the vessels are removed, the remedial
action will also include cleanup of affected surficial soils.
A Final Remedial Design Report for SVE operations was submitted on June 14, 1994.
The groundwater remedy design was separated from the SVE design to allow the MDSG to
conduct studies of the applicability of bioremediating volatile organic constituents on source area
groundwater. Currently, one SVE system and four groundwater pump and treat systems are in
operation at the site.
The MDSG undertook the waste removal phase of the Remedial Action beginning in June
1994. The waste removal phase included removal of Lagoon IO wastes, various process and
storage vessels associated with previous operations, and wastes generated during previous
investigation activities. Waste removal activities were completed in November 1994.

2.0 Purpose
The purpose of this Sampling and Analysis Plan (SAP) is to document soil conditions in
the area of former Lagoon 7 of the Macon Dockery Superfund site. The SAP provides
descriptions and details of the proposed procedures for soil verification sampling and subsequent
regulatory reporting. Since the installation of the SVE unit at Lagoon 7, SVE exhaust and
extraction well point air samples have been collected on a quarterly and semi-annual basis .
respectively. A review of recent and historical air sample data from samples collected in relation
to the SVE system have consistently been below the air emissions Performance Standards
established for the site. The following SAP provides details and descriptions of the proposed
procedures for assessing the subsurface soils in the area of former Lagoon 7. The goal of the
proposed soil assessment in the area of former Lagoon 7 is to determine if SVE operations have
reduced COC concentrations to below the Performance Standards for the site.
3.0 Soil Vapor Extraction System
The SVE system installed in the area of former Lagoon 7 was installed to remediate
vadose zone soils beneath the former lagoon. The SVE system consists of a series of SVE wells
used for vacuum extraction and soil venting. Remediation at Lagoon 7 initiated on February 22,
1996, by soil vapor extraction (SVE). Since system start-up, the system has operated a large
vacuum unit that induces vacuum on SVE wells VE-I, OW-I, OW-3, and OW-5 to recover soil
vapors. Vapors captured by the SVE system are discharged to the atmosphere through a vertical
discharge stack. Ambient air enters the vadose through the ground surface and through two soil
venting wells (OW-2 and OW-4). Figure 2 details the layout of the SVE system and associated
SVE wells.
The SVE system has extracted vapors from wells VE-I, OW-I, OW-3, and OW-5 since
start-up. Air samples have been collected from extraction well points and the exhaust side of the
SVE system on a quarterly, and semi-annual basis, respectively. Air samples collected in
association with the SVE system are analyzed for volatile organic compounds (VOCs) by EPA
Page No. 4
•
Method 18. A review of the historical SVE system effluent results indicates that air samples
collected from the individual SVE points and the SVE exhaust stack have been below the
laboratory detection limits for volatile organic compounds (VOCs) since November 1997. For
this reason, the Macon Dockery Site Group (MDSG) believes that there is sufficient technical
justification to warrant the closure of the SVE system. A summary of the analytical results
associated with the SVE system are attached as Table 1.
4.0 Sample Collection Procedure
As detailed in Section 3.1.8 of the Performance Standards Verification Plan (PSVP) dated
July 11, I 994, AES proposes to collect soil samples from four soil borings advanced within the
perimeter of former Lagoon 7. The soil borings will be located on two perpendicular axes of
Lagoon 7 and approximately 10 feet on either side of the lagoon center. Section 3.1.6 of the
PSVP inadvertently states that the confirmatory soil borings will be located on two perpendicular
axes of Lagoon 7 and approximately 20 feet on either side of the lagoon center. The MDSG
believes that the soil borings should be located on two perpendicular axes of Lagoon 7 and
approximately IO feet on either side of the lagoon center since locating the borings
approximately 20 feet on either side of the lagoon center would place the borings on the
east/west axis outside of the estimated boundary of the former lagoon. Figure 3 shows the
locations of the proposed confirmation soil borings.
The soil borings will be advanced using continuous flight hollow stem auger with a split
spoon sampler used to collect the subsurface soil samples for the verification sampling. As
stated in the PSVP, confirmatory soil samples will be collected at the 22 to 24-foot depth interval
and the 29 to 31-foot depth interval from each of the four soil borings. However, Section 2,
paragraph 2 of the Final Remediation Design Report for the SVE System states that "during the
RI, PCE was detected at a concentration of 31 mg/kg at the 25 to 27 foot depth in soil boring SB-
7, which is located in former Lagoon 7." To account for this discrepancy and assure that this
interval is assessed during the soil confirmation sampling, the MDSG proposes to collect
Page No. 5
•
continuous split spoon soil samples beginning at 20 feet below grade level (BGL) and
terminating at 32 feet BGL.
All drilling and sampling activities associated with the confirmatory sampling will be
conducted under the direction of a professional geologist or professional engineer registered in
the state of North Carolina. The soil borings will be installed by advancing hollow stem augers to
32 feet below grade. Undisturbed soil samples will be collected using a stainless steel split
spoon sampler advanced in two-foot intervals through the augers. The split spoon sampler will
retrieve soil samples from the following depth intervals below grade: I 0-12 feet: 15-17 feet: 20-
22 feet: 22-24 feet: 24-26 feet: 26-28 feet: 28-30 feet: and 30-32 feet.
Soil cuttings and soil recovered in the split spoon samplers will be described with a
lithologic description. In addition, soil cuttings and soil recovered in the split spoon samplers
will be field screened by headspace analysis. The collected soil samples will be placed into
plastic air-tight bags and screened with an organic vapor analyzer equipped with a
photoionization detector (PID).
Soil samples collected for laboratory analysis will be collected from the split spoons
advanced at the 22 to 24-foot interval and the 28 to 30-foot interval. In addition, one soil sample
will be collected for laboratory analysis from the interval exhibiting the highest PID reading. If
there are no PID readings above the detection limit, or the highest reading occurs in the 22 to 24-
foot or 28 to 30-foot depth intervals; only two (2) samples will be collected from the boring for
laboratory analysis. All drilling and sampling activities will be conducted in accordance with the
PSVP for the Macon/Dockery Site and the US EPA Region IV Environmental Investigations
Standard Operating Procedures and Quality Assurance Manual.
Drilling equipment will be decontaminated according to the procedures outlined in
Section 4.0 of this report. Decontamination procedures will occur between each boring in the
designated decontamination area. The downhole equipment will not be allowed to come into
Page No. 6
•
contact with potentially contaminated materials until boring operations commence.
Following completion of each boring, the borings will be abandoned with a
water/cement/bentonite mixture with a ratio of approximately 3 :6: I. Soil cuttings generated by
the installation of the borings will be placed into 55-gallon drums and stored in a designated
storage area on-site.
5.0 Sam pie Analysis
The soil samples collected for laboratory analysis will be placed into a four ounce,
laboratory supplied, glass sample jar equipped with a Teflon lid. For the purposes of the soil
confirmation sampling, the chain-of-custody procedures outlined in Section 4-1 of RMT's Field
Sampling and Analysis Plan dated June 1994 will be followed. By the use of chain-ot:custody
procedures, the handling of samples will be traceable from the time of sample collection to the
time of final disposition. Field personnel will record the sample number, date and time of
sample collection, personnel involved, type of sample, type of analysis to be performed, type of
containers filled, volume of sample collected, and preservatives used. Field measurements such
as sample depth, location, and PIO reading will be recorded in the sample personnel's field notes.
Soil samples collected for analysis will be placed into a cooler pre-packed with ice. A
temperature blank inside of the pre-packed cooler will be used to assure that the samples
maintain a temperature of no greater than 4-degrees Celsius (C). Prior to shipment, the cooler
will be sealed with adhesive custody seals to assure that the samples are not disturbed during
shipment. Soil samples will be shipped, via overnight delivery, to STL Savannah Laboratories,
Inc. (STL), a North Carolina Certified Laboratory, in Savannah, Georgia. The MDSG will
request that the soil samples be analyzed for VOCs by EPA Method 8260, with a method
quantitation limit no greater than 0.5 mg/kg. STL will extract the soil samples prior to the
expiration of the 14-day hold time.

6.0 · Decontamination/Health and Safety Procedures
Large drilling apparatus including drill augers, bits, and the back of the drill rig, will be
steam cleaned prior to beginning boring operations and again in between each boring. Soil
sampling equipment, including split spoon samplers, will be decontaminated before sampling
and between the collection of each sample. Soil sampling equipment will be decontaminated in
accordance with the US EPA's Region IV Environmental Investigations Standard Operating
Procedures and Quality Assurance Manual and Section 11.0 of the Site Health and Safety Plan
for the Macon/Dockery Site. Soil sampling equipment will be decontaminated using the seven-
step decontamination procedure listed below.
I . Scrub brushed using clean tap water and laboratory detergent.
2. Tap water rinse.
3. Deionized organic-free water rinse.
4. Isopropanol rinse.
5. Deionized organic-free water rinse.
6. Air dry
7. Equipment will be wrapped with plastic or aluminum foil to minimize the
possibility of contamination.
Decontamination procedures will be performed on a decontamination pad designed to
collect all liquid and particulate matter resulting from such procedures. The decontamination pad
will be constructed on the existing concrete pad (formerly used as a decontamination pad) near
the Macon Source Area groundwater pump and treat system. The decontamination pad will' be
12-foot by 12-foot in size and constructed of6 millimeter thick plastic inside of four foot by four
foot rails. All decontamination procedures will be conducted on the decontamination pad. The
Page No. 8
•
decontamination pad plastic, liquid, and particulate matter accumulated from the
decontamination procedures will be placed into 55-gallon drums and stored on-site.
All drilling and sampling activities occurring at the site will be conducted in accordance
with the Site Health and Safety Plan prepared for the Macon/Dockery Site by Handex of the
Carolinas dated June I 995. Drilling and sampling personnel will be equipped with Level D
personal protective equipment including latex gloves, Tyvek suits, hard hats, steel toed safety
boots, and safety glasses. Disposable personnel protective gear (i.e. gloves, Tyvek suits) will be
placed into 55-gallon drums and stored on-site. Provisions will be available onsite for upgrade to
Level C personal protection equipment should conditions warrant.
7.0 Disposal of Drummed Materials
If analysis of the sampled intervals indicate that the PCE concentration in soil is
less than 3.0 mg/kg, the Performance Standard for PCE at the Site, then the drummed soil
cuttings will be spread onsite and the used Tyvek and other disposable sampling materials will be
disposed in a secure landfill in accordance with Federal, State, and local regulations. Should the
analyses indicate PCE concentrations greater than 3.0 mg/kg, then the drummed soil and
sampling materials will be transported and disposed at an appropriately licensed facility. In the
event that compounds other than PCE are detected in the soil samples, the US EPA and
NCDENR will be consulted in order to determine the appropriate method of disposal for the
drummed soil cuttings. Collected rinse water will be slowly combined with the influent water of
the Macon Dockery Source Area groundwater treatment system. The rinse water will be
discharged into the remediation system at a point prior to the sediment filters in order to avoid
potential problems from the presence of naturally occurring metals or from sediment deposition
itself.
8.0 Reporting
Page No. 9
•
Following receipt of the laboratory analytical results, a report of the results will be
presented to the US EPA, NCDENR, and MDSG members. The report will include all data
collected during the soil sampling event such as field notes, lithologic descriptions, headspace
analytical results, and laboratory analytical data. The data will be presented in a Completion
Report and will include all associated text, tables, and site figures. The report will also
recommend a future course of action at former Lagoon 7.
Drilling activities and the associated laboratory analytical results will result in one of four
scenarios. The following section describes the four scenarios and their potential outcomes:
I. PCE meets the Performance Standard and no additional compounds are detected.
2. PCE meets the performance standard and additional compounds are detected.
3. PCE does not meet the Performance Standard and no additional compounds \Ire
detected.
4. PCE does not meet the Performance Standard and additional compounds are
detected.
Scenario I provides evidence that the SVE Performance Standards have been met, that all
SVE operations are complete and that the SVE system may be turned off. Scenario 3 and
Scenario 4 provide evidence that the SVE Performance Standards have not been met, that
operation of the SVE remediation system must continue, and that the MDSG shall submit a
report suggesting strategic modifications to the SVE system such that contaminant
concentrations are removed from the subsurface more efficiently. Scenario 2 and Scenario 4
present the problem of additional contaminants present at the site. In the event this situation
arises, the MDSG will consult with the US EPA and NCDENR in order to determine the
appropriate performance standard for each contaminant detected. In the event that the levels of
each of the detected contaminants are below their respective Performance Standard, operation of
the SVE system may be considered complete and SVE operations discontinued. However, in the
event that the levels of each of the detected contaminants are not below their respective
Page No. 10
•
Performance Standard, operation of the SVE system may not be considered complete and SVE
operations must continue. Additionally, the MDSG shall submit a report suggesting strategic
modifications to the SVE system such that contaminant concentrations are removed from the
subsurface more efficient! y.
In the event that the remediation is not complete and the SVE process cannot be modified
to address the contamination, the MDSG will submit an alternate remediation strategy for
Lagoon 7.
9.0 Schedule
Upon approval of the Sampling and Analysis Plan, the MDSG anticipates completing the
work in accordance with the Schedule presented in Figure 4 of this report.

COMMENTS
SAMPLING AND ANALYSIS PLAN -LAGOON 7
1. Section 1.0, Introduction -Please revise Section 1.0 to include much greater detail.
Section 1.0 should include a brief summary of the Site, including, but not limited :to,
descriptions of the site location (including applicable figures), former/current land use
including activities at the Site that contributed to the contamination, nature and extent
of contamination at the site, regulatory history including applicable performance
standards, remedial activities conducted to date, remediation system operational history
and status, etc. Please revise Section 1.0 accordingly.
2. Section 2.0, Sample Collection Procedure-Section 3.1.6 of the Performance Standards
Verification Plan (PSVP) indicates that confirmatory soil samples are to be collected
from the 22-24 foot depth interval and the 29-3~ foot depth interval from four soil
borings located on two perpendicular axes of Lagoon 7 and approximately tenfeet on
either side of the lagoon center. However, Section 3.1.8 of the PSVP indicates that
confirmatory soil samples are to be collected from the 22-24 foot depth interval and the
29-31 foot depth interval from four soil borings located on two perpendicular axes of
Lagoon 7 and approximately twenty feet on either side of the lagoon center. Please
clarify this discrepancy by submitting a figure depicting the extent of contamination and
proposing a sampling scheme in Section 2.0, based upon the schemes presented in the
PSVP, that will best determine the presence or absence of contamination at Lagoon 7.
Please include the appropriate discussion in Section 2.0 supporting the rationale for the
proposed soil-sampling scheme.
3. Please revise Section 2.0 to include a reference to the attached Soil Boring Location
Map.
4. The third paragraph of Section 2.0 indicates that the lithological description is to be
conducted by a geologist or engineer. Please revise Section 2.0 to include provisions
for conducting all drilling and sampling activities under the direction of a professional
geologist registered in the State of North Carolina.
· 5. The third paragraph of Section 2.0 indicates that the lithological descriptions are to 'be
made of the two-foot interval in which soil samples are to be collected. Please include
provisions for determining the lithology of the remainder of the soil boring from soil
cuttings generated during drilling activities. Additionally, please provide provisions for
screening the drill cuttings by conducting headspace analysis with a flame ionization
detector (FID) and/or a photoionization detector (PIO) in order to ascertain the absence
or presence of contaminants in the remainder of the soil boring. Section 2.0 should also
include provisions for the collection of additional soil samples for laboratory analysis in
the event that headspace analysis indicates the presence of contaminants in intervals
other than those proposed for sampling.
6. Please revise the third paragraph of Section 2.0 to include a sentence stating that, at
a minimum, all drilling and sampling activities will be conducted in accordance with the
-1-
• •
Performance Standards Verification Plan (PSVP) for the Site, and the United States
Environmental Protection Agency (US EPA) Region IV Environmental Investigations
Standard Operating Procedures and Quality Assurance Manual (EISOPQAM).
7. Section 3.0, Sample Analysis -Please revise Section 3.0 to include greater detail
including, but not limited to, the sample container type and volume, method of sample
preservation, sample holding time, and chain of custody procedures. Additionally,
please revise Section 3.0 to include provisions for the laboratory analysis of the soil
samples for all volatile organic compounds (VOCs) available by US EPA Method 8260.
This will provide a means of detecting degradation compounds in the event that the
remediation system has not performed as expected and natural attenuation processes
have been occurring.
8. Section 4.0, Decontamination/Health and Safety Procedures -Please revise the second
sentence of Section 4.0 to state, "Sampling equipment will be decontaminated· in
accordance with the United States Environmental Protection Agency (US EPA) Region
IV Environmental Investigations Standard Operating Procedures and Quality Assurance
Manual (EISOPQAM)."
8. The second paragraph of Section 4.0 indicates that decontamination activities shall be
performed on a decontamination pad designed to collect all liquid and particulate matter
resulting from decontamination activities. Please revise Section 4.0 to include greater
detail regarding the description of the construction and use of the equipment and
personnel decontamination pad. ·
9. Section 4.0 briefly details the health and safety procedures to be implemented during
sampling activities at the Site. Please include the health and safety plan to be employed
during sampling activities at the Site. Please bear in mind that the health and safety
plan must include provisions for air monitoring and personal protective equipment
upgrades.
10. Section 5.0, Disposal of Drummed Materials Please revise the first sentence of Section
5.0 to state, "If analyses of the sampled intervals indicate that the PCE concentration
in soil is less than 3.0 mg/kg, the performance standard tor PCE at the Site, then the
drummed soil cuttings will be spread onsite and the used Tyvek and other disposable
sampling materials will be disposed in a secure landfill in accordance with Federal,
State, and local regulations." Additionally, please insert the following sentence following
the first sentence in Section 5.0: "In the event that compounds other than PCE are
detected in the soil samples, the US EPA and the NC DENR will be consulted in order
to determine the appropriate method of disposal tor the drummed soil cuttings."
11. The last sentence indicates that the collected rinse water will be slowly combined with
the influent water of the Macon Dockery Source Area groundwater treatment system.
Please bear in mind that the collected rinse water should be combined with the influent
water at a point prior to the sediment filters in order to avoid potential problems from the
presence of naturally occurring metals or from sediment deposition itself.
-2-
•
12. Section 6.0, Reporting -Please revise the second sentence of Section 6.0 to state,
"The report will include all data collected during the soil sampling event such as field
notes, lithologic descriptions, headspace analytical results, and laboratory analytical
data."
13. Please revise Section 6.0 to include provisions for the following four scenarios and their
potential outcomes:
1. PCE meets the performance standard and no additional compounds are
detected.
2. PCE meets the performance standard and additional compounds are detected.
3. PCE does not meet the performance standard and no additional compounds are
detected.
4. PCE does not meet the performance standard and additional compounds are
detected.
Scenario 1 provides evidence that the soil vapor extraction (SVE) Performance
Standards have been met, that all SVE operations are complete and that the SVE
system may be turned off. Scenario 3 and Scenario 4 provide evidence that the SVE
Performance Standards have not been met, that operation of the SVE remediation
system must continue, and that the Macon Dockery Site Group (MDSG) shall submit a
report suggesting strategic modifications to the SVE system such that contaminant
concentrations are removed from the subsurface more efficiently. Scenario 2 and
Scenario 4 present the problem of additional contaminants present at the site. In the·
event that this situation arises, the US EPA and the North Carolina Department:of
Environment and Natural Resources (NC DENR) must be consulted in order to
determine the appropriate performance standard for each contaminant detected. In the
event that the levels of each of the detected contaminants are below their respective
performance standard, operation of the SVE system may be considered complete and
SVE operations discontinued. However, in the event that levels of each of the detected
contaminants are not below their respective performance standard, operation of the
SVE system may not be considered complete and SVE operations must continue.
Additionally, the MDSG shall submit a report suggesting strategic modifications to the
SVE system such that contaminant concentrations are removed from the subsurface
more efficiently.
In the event that the remediation is not complete and the SVE process cannot be
modified to address the contamination, the PRPs may submit an alternate remediation
strategy for Lagoon 7.

1.0 Introduction
The purpose of this Sampling and Analysis Plan (SAP) is to document soil conditions in
Lagoon 7 of the Macon Dockery Supcrfund site. Remediation at Lugoon 7 initiated on February
22, 1996, hy soil vapor extraction (SYH). The SVE system has extrnctcd vapors from wells VE-
1, OW-1, OW-3, and OW-5. J\ir samples have been colleckd from observation wells and the
effiuent side of the SYE system on u semi-annual, nnd gum1erly basis, respectively. The air
samples have been analy,.ed for volatile organic compounds (VOCs) by EPA Method 18. A
review of the historical SVE system effluent results indicates that air samples collected from the
individual SVE points and the SVE exhaust stack huve been below the luborutory detection
limits for volatile organic compounds (VOCs) since November 1997. For this reason, the Macon
Dockery Site Group (MDSG) believes that there is sufficient technical justification to warrant
shutting down the SYE system. A summary of the analytical r<;,sults are attached as Table I.
2.0 S11mplc Collection Procedure
As detailed in Section 3.1.6 of the Performance Standards Verification Plan (PSVP) dated
July 11, 1994, AES proposes to collect soil samples from four soil borings advanced within the
perimeter of former Lagoon 7. The soil b(1rings will be located on two perpendicular axes of
Lagoon 7 ,llld approximately 10 feet on either side of the lagoon center. Confirmatory soi)
samples will be collected at the 22 to 24-foot depth interval and the 29 to 31-foot depth interval
from each of the four soil borings.
The soil borings will be advanced using continuous flight hollow stem auger with u split
spoon sampler used to colkct the subsurface soil samples for the veri!katiun sampling. Drilling
equipment will be decontaminated according to the procedures outlined in Section 4.0 of this
report. Decontamination procedures will occur between each boring in the designated
Page No. 1
NORTH· SU?ERFUND ID: MRR 02'00 15:30 N □.004 P.05 •
dccontumination area. The do\\11hole equipment will not be allowed to come into contact with
potentially contaminated materials until boring operations commence.
13orcholcs will he installed by advancing hollow stem augers to 22 feet below grade.
Once the boring reaches a depth of 22 feet below grade, a continuous soil sa111ple will be
collected to a depth of 24 feet below grude using a stainless steel split spoon sa111pler. After
collection of this soil sample, the hollow stem augers will advance to 29 feet below grade. A
stainless steel split spoon sampler will he used to collect a continuous soil smnple from the 29 to
31 foot depth interval. Each 2-foot interval recovered by the split spoon samplers will be
described with a lithologic description hy a geologist or engineer. Following completion or each
boring, the borings will be abandoned with a water/cement/bcntonitc mixture witJ1 a ratio of
approximately :1 :6: 1. Soil cuttings generated by the installation of the borings will be placed into
55-gallon drums and stored in u designated storage area on-site.
3.0 Sample Analysis
The soil samples from each boring obtained from the two intervals specified ubove will
be placed into lahuratory supplied glass sample jurs with Teflon seals. F(illowing the chain-of-
custody procedures outlined in Section 4-1 ofRMT's Field Sampling nnd Analysis Plan dated
June l 994, AES will suhmit the soil samples via overnight delivery to STL Savwmah
Laboratories, Inc. in Savannah, Georgia. AES will request that the soil samples be analyzed for
tctrachloroethene (PCE) by EPA Method 8260, with a method quuntitution limit no greater than
0.5 mg/kg. Figure I shows the locations of the proposed confirmation s<>il borings.
4.0 Dccontaminallon/He11lth and Safety Procedures
Soil sampling e4uipment will be dccontan1inated before sampling and between the
collection of each sample. Sampling equipment will he decontaminated with materials specified
in the US P.PA 's Environmental Services Brand, Standard Operating Procedures and Quality
Page No. 2
NORTH. SUPERFUND ID: MRR 02 '00 15:31 No.004 P.C5 •
Assurance Manual. Soil sampling equipment will he decontaminated using the seven step
decontamination procedure listed below.
1. Scrub brushed using clean (ap water and laboratory detergent.
2. Tap water rinse.
3. Deionized organic-free water rinse.
4. Isopropanol rinse.
5. Deionized organic-free water rinse.
6. Air dry
7. Equipment will be wrapped with plastic or aluminum foil to minimi~.e the
possibility of contamination.
Large drilling apparatus including drill augers, bits, and the back of the drill rig,
will he steam cleaned prior to beginning boring operations. Decontnmination procedures
will be performed on a decontwnination pad designed to collect all liquid and particulate
matter resulting from such procedures, The decontamination pad, liquid, and pnrticulatc
matter accumulated from the drilling operations will be plnced into 55-gallon drums and
stored on-site.
Drilling and sampling personnel will be equipped with Level C personal
protective equipment including latex gloves, Tyvek suits, hard huts, steel toed safety
boots, and safety glasses. P~rs01mel directly involved with drilling and sampling
procedur~s must pass through the decontwnination pad prior to exiting the work area.
Disposable personnel protective gear (i.e. gloves, Tyvek suits) will be placed into 55-
gullon drums and stored on-~ite. Remaining non-disposabl~ personal protective geur will
be washed and rinsed inside th~ decontamination pad.

5.0 Disposal of Drumm rd Materials
lf analysis of the sampled intervals indicate that the PCE concentrntion in soil is
less than 3.0 mglkg, then the drummed soil cuttings will he spread onsitc and the used
Tyvtok and other disposable sampling materials will be sent to the local landfill. Should
the analyses indicate PCE concentrations greater than 3.0 mg/kg, then the drummed soil
and sampling materials will be transported and disposed at an appropriately licensed
facility. Collected rinse water will be slowly combined with lhti influent water of the
Macon Dockery Source Arca groundwater treatment system.
6.0 Reporting
Should analyticul data demonstrate that PCE levels arc below the Performance
Standard of3.0 mg/kg, MDSG will transmit these findings to the US EPA as evidence
that all SVE opemt.ions arc complete and that SVE Performance Stru1dards have been
met, The report will include u/1 data collected during the soil sampling event such as
field notes, lithologic descriptions, and laboratory anulytical data. The data will be
presented in a Completion Report to US EPA and will include all associutcd text, tables,
and site figurtos. Should laboratory analytical results indicate results in excess of the PC:h
Performance Standard of 3.0 mg/kg, the SVE system will be restarted. The MDSG will
transmit tl1ese findings lo the US EPA as evidence that SVE operations are not complete.
The report will include all data collected during the investigation along with suggested
strategic modific~tions to the SVE system such that PCE concentrations ru·e removed
from the subsurface more cfliciently.
7.0 Schedule
Upon approval of the Sampling and Analysis Plan, the MOSG anticipates

Re: Maconillockery Site -Cordova, North Carolina
Request on Reduction in Laboratory Sampling
Dear Ms. Bennen:
PAGE 02
Since system stan up in early February 1996, the Macon/Dockery Site Group has collected many IOW1ds 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 aruilytical pwametenl that have consistently been below the Remediation Performance Standard or below the detection limit. The analytical parameters are discussed below.
Isophoronc, a semivolatile analyzed by EPA Method 8270 has been consistently reported to be below the detection limit in all influem and effluent system samples and in the compliance monitor wells. A review of the Final Remedial Design Report by RMT had three wells sampled in March 1993 that detected isophorone from 3 J µg;L to 4 J µg/L. The Remediation Performance Standard is 70 µg/L.
Mercury by EPA Method 7470 has been detected once at the Macon Source Area in the influent at' 0.22 µg/L and once in the effluent at 0.26 µg/L. These concentrations are an oroer of magnitude below the Remediation Performance Standard of 1.1 µg/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 Penormnncc Standard.
Cyanide by EPA Method 9010 he,i consistently been reported below the detection limit in all of the '· system samples but was detected once at 0.019 flg/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 µg/L.

The Macon/Dockery Site Group requests that EPA Methods 8270, 7470, and 90 IO 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, MW!:i, MWl9, 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 quanerly. The effluent will continue to be sampled monthly;
The Monthly Progress and O & M Report for May 1996, documented the mass voe removal based
on the analytical n::sults from the influent and effluent concentrations. If these total voes were passed through the air stripper, the total pounds released to the atmosphere would be below the air diS<lhnrge permit, RMT in the: Operation and Maintenance Plan calculated the air stripper air, emission rates find a worst case air emi:ssion rates from the soil vapor extraction unit. All values
' were below the 40 pounds ofVOC emissions per day and below the thresholds for individual air
toKins.

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 Nolth 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 groWJdwater 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.
