Dear Mr. Townsend:
On behalf of General Electric, please find the Laboratory Reports along with their
QC data from the September Sampling Event enclosed in digital format. If there are any
problems accessing data on the CD please call me.
Also, there is an upcoming quarterly monitoring event. For this event we will be
sampling the treatment building only. The sample collected will be analyzed for volatiles
(VOCs) and metals. The sampling is tentatively set for the third week in December and
will be conducted by either me or Jim Huang. If that date changes, you will be notified.
Results of the analysis will be forwarded on to you once they are received.
If you have any questions please call Barry Hallock at 828-693-2148 or contact
me via email at [e-mail] or by phone anytime.

GE/Shepherd Farm Site, East Flat Rock, NC
Geo Trans Project No. PS21-00 I
Dear Ms. Bennett:
General Electric is actively conducting performance monitoring at the above referenced site for the
groundwater remediation system (GRS). On behalf of General Electric, this letter is submitted to the Agency
to formally request that the sample frequency for Nitrobenzene in groundwater be reduced from quarterly
to annually.
In accordance with the Remedial Goal Verification Plan, a formal request in sample frequency can
be made after at least four consecutive temporal measurements from the given monitoring points within a
subsite indicate a given remediation target compound (RTC) is consistently below its cot-responding Record
of Decision (ROD) remediation goal. Nitrobenzene has not been detected in groundwater above the
remediation goal at either the GE or Shepherd Farm Subsites for six consecutive temporal (i.e .. quarterly)
measurements. Performance well analytical results since the start ofGRS operation arc attached. The sample
frequency will revert back to quarterly in the event that Nitro benzene is detected above the remediation goal
during any of the next three annual sampling events.
Thank you for considering this request. A response to this request by March I, 2002 would be
greatly appreciated in order to incorporate the proposed changes into the scheduled March sampling event.
Please feel free to call me with any questions you may have.

Dear Ms. Bennett:
RECEJVED
MAY 18 2000
SUPERFUND SECTION
On behalf of General Electric Company (GE), HSI Geo Trans Inc. (HSIG) will be
performing the next regularly-scheduled quarterly groundwater sampling event in June
2000. The quarterly event consists of sampling four recovery wells and nine performance
monitor wells for volatile organic compounds (VOCs), semi-volatile organic compounds
(SVOCs) and metals. These wells are sampled to evaluate the performance of the
Accelerated Groundwater Remediation System (AGRS) which consists of four recovery
wells extracting a total of approximately 25 gallons per minute.
REQUEST TO PERFORM ADDITIONAL GROUNDWATER SAMPLING AT
THE GE SUBSITE
During the June 2000 quarterly sampling event, GE proposes to sample an
additional 27 wells at the GE Subsite for VOCs. The objective of the additional
groundwater sampling is to determine the VOC mass currently present in the
groundwater across the entire GE Subsite so that a more complete assessment of the
AGRS performance can be achieved.
Figure I shows to location of all 40 wells proposed to be sampled. Thirteen of the
40 wells will be sampled as part of the current performance monitoring network, as
described above. The other 27 wells were proposed because they were either part of the
1997 baseline sampling event or because they are part of the proposed final remedy
monitoring network. Table I lists the wells proposed to be sampled and details the
purpose of sampling each well. GE proposes to use the same sample collection and
P:IGEIOOCSIEPA\Epa75.wp,l
•
analysis methods in June 2000 as were used during previous groundwater sampling
events (i.e., low-flow sampling methods are not being proposed for the June 2000
sampling).
All of the wells proposed as part of the long-term monitoring network for the final
remedy at the GE Subsite are proposed to be sampled in June 2000. In addition, all of the
1997 baseline wells will be sampled again in June 2000 with two exceptions. Monitor
well MW-9 has been abandoned and cannot physically be sampled. Monitor well MW-
14B does not reliably recharge thus provides questionable data. Monitor well 14B had to
be purged dry and sampled 16 hours later. Water levels collected over time show that is
took about a year for the well to fully recover. Deep bedrock water quality data will be
provided from two other wells (MW-12B and MW-20B).
REQUEST TO CHANGE PARAMETER LIST
GE further proposes to discontinue the analysis of groundwater for NPDES permit
monitoring compounds. Ten compounds were previously routinely analyzed for because
treated groundwater was discharged into Bat Fork Creek. Since GE does not currently
discharge treated groundwater to Bat Fork Creek, nor intends to discharge treated
groundwater to Bat Fork Creek in the future, GE proposes to discontinue analyzing
groundwater for these IO NP DES compounds which include bromodichloromethane, 1, 1-
dichloroethane, 1,2-dichloropropane, I, 1,2,2-tetrachloroethane, bis (2-ethylhexyl)
phthalate, napthalene, cobalt, iron, mercury and zinc. The remediation target compounds
(RTCs), listed in Table 2, will continue to be analyzed for which include seven VOCs,
one SVOC, and five metals.
I hope that these proposed groundwater sampling actions meet your approval.
Please feel free to call Janet Boyer at 828-693-2505 or me if you have any questions or
comments.

Monitor well MW-19 was a key location for calculating VOC mass due to large mass gradient in
that area. The well was not sampled in 1997 so 1994 data were used for MW-19 for calculating
VOC mass for 1997 baseline conditions.

SUPERFUND SECTION
On behalf of General Electric Company (GE), HSI GeoTrans Inc. (HSIG) submitted to
the Agency a final design for groundwater remediation at the above referenced site (HSIG,
2000). Long-term groundwater quality performance monitoring is a component of the final
groundwater system. The final design proposes to use dedicated bladder pumps and low-flow
sampling techniques to generate high-quality groundwater quality data from the monitor
wells. Ms. Lynne France of COM requested an opportunity to review the proposed Standard
Operating Procedures (SOPs) for collecting the groundwater samples using low-flow
methods. Attached for your review are the subject SOPs. These SOPs, if approved, would be
included in a revised final design.
I hope that the enclosed SOPs adequately address any questions you may have about the
proposed methods. Ms. Diane Guthrie with EPA in Athens, Georgia (706-355-8622) offered
to be available to answer any technical question about low-flow sampling. Otherwise, please
feel free to call Janet Boyer at 828-693-2505 or me if you have any remaining questions or
comments.

STANDARD OPERATING PROCEDURES FOR
LOW-FLOW WELL PURGING AND SAMPLE COLLECTION
•
INTRODUCTION
This document details the standard operating procedures (SOPs) for groundwater monitoring well
purging and sample collection using the low-flow purging and sampling method at the GE and
Shepherd Farm Subsites. The low-flow method is being implemented as the elected procedure to
minimize aeration, mixing, and disturbance of the well water column, and it is expected to maximize
the validity and accuracy of the resulting analytical data.
The low-flow purging and sample collection technique has been approved by the regulatory agencies
having jurisdiction over the site. Deviation from this SOP will not be allowed unless approval is
granted to field personnel by the HSI GeoTrans (HSIG) Project Manager and the Agency.
A total of twenty groundwater wells are scheduled for sample collection on a quarterly basis.
Sixteen of the wells are located on the GE Subsite, and the remaining four are located at the
Shepherd Farm Subsite. Each well is to have at least the following dedicated equipment installed
and ready for use upon arrival at the site:
• Downhole low-flow well pump;
• Downhole water level sensor; and
• Associated pump manufacturer's well cap, tubing, connections, etc. for connecting
to the downhole equipment.
The twenty wells are to be purged using the low-flow technique. After indicator parameters stabilize
samples will be collected for the following water quality parameters: I) seven volatile organic
compounds (VOCs); 2) one semi-volatile organic compound (SVOC); and 3) five metals. The
remediation target compound list may be revised pending regulatory agency approval. Table A4-l
summarizes the required sample containers, sample hold times, and analytical methods for the
scheduled analyses.
WELL SAMPLING PREPARATION ACTIVITIES
Prior to mobilization to the field and collection of groundwater samples, the field personnel
responsible for the site work will read this SOP and acquaint themselves with the purging and
sampling procedures contained herein. Any materials and equipment necessary for well sampling
task will be procured prior to the site visit. If such supplies require shipping, arrangements will have
been made to make the supplies available at the time of mobilization to the site.
In addition, field personnel will review applicable manufacturer owner's and/or operating manuals
for the low-flow pump and controller, flow-through cell apparatus, and water level indicator prior
to commencing work and mobilizing to the site. It is imperative field personnel are familiar with
any and all equipment to be used during low-flow well purging and sample collection before
initiating field activities. Literature accompanying the field equipment ( e.g., owner's manual,
•
operating manual, troubleshooting guide, etc.) will be readily available for reference at the site.
The following is a list of non-dedicated materials and equipment required for performing the well
purging and sampling task:
• Power source (usually purchased or rented from a distributor or representative of the
low-flow pump manufacturer);
• Controllers and other equipment associated with the dedicated downhole equipment
(low-flow pump) manufacturer;
• Teflon or teflon-lined polyethylene tubing;
• Manual, electronic water level meter (as a back-up measurement device);
• Flow-through cell water quality meter or device(s) capable of measuring dissolved
oxygen (DO), oxidation/reduction potential (ORP), specific conductivity ( cond), pH,
temperature (T 0
), and turbidity (turb);
• Graduated cylinder to check low-flow rate;
• Graduated buckets or containers of known volume capacity to measure purge water;
• Laboratory sample pack including cooler(s), sample containers, blanks, and
laboratory-supplied quality assurance/quality control (QA/QC) samples (trip blanks);
• Chain-of-custody forms;
• Blank groundwater sampling records or logs (one for each well);
• Clean plastic sheeting for each well;
• Field notebook, pens, site map with well locations, and well keys;
• Calibrated photoionization detector (PID) or flame ionization detector (FID); and
• Site Health and Safety Plan (HASP) and the appropriate health and safety equipment
as specified in the HASP.
CHRONOLOGICAL LOW-FLOW WELL PURGING AND SAMPLING PROCEDURES
The following is a step-by-step list of procedures to be followed during monitoring well purging and
sample collection activities. The list is provided in chronological order.
•
I. Review the Well Sampling Preparation Activities checklist provided above to
confirm all material and equipment is available for use and in working order;
2. Record the date, arrival time, weather conditions, and personnel on site to perform
the task. Record any other pertinent site information or data requested on the
Groundwater Sampling Record or Log Sheet (attached at end of this section);
3. Label all sample containers if not already done so by the project laboratory. Leave
the sample time and date fields blank until after sample collection;
4. Don the required personal protective equipment as stipulated in the HASP;
5. Place clean plastic sheeting around the well to be sampled in order to provide a clean
work area;
6. Record the site's background measurement for airborne volatile compounds with the
PIO or FID. Record the measurement in the field notebook. Historically, VOCs
have never been detected at or near the wells;
7. At each well scheduled for sampling, unlock the well lock. Open the well cover(s)
while standing upwind of the well. Measure the breathing zone with the PIO or FID
immediately above the wells to be sampled. Based on each field measurement,
follow the instructions stipulated in the HASP. If no subsequent action is required
by the HASP, record each breathing zone measurement in the field notebook and on
the sampling record or log. Prepare to collect all water level data. (NOTE: Water
level data from each well scheduled for sampling will be obtained on the same day
and before purging and sampling of any well. The water level data collection will
be the first subtask completed.)
8. Prepare the water level sensor for use. Use a manually-operated, electronic sensor
prior to initial installation of the dedicated downhole equipment. Thoroughly clean
the manual sensor with an Alconox®-water solution, and rinse with potable and
distilled water. If downhole equipment has been previously installed, connect the
water level data collection device to the dedicated water level sensor and record the
data in the field book and sampling record/log. (NOTE: This site has not historically
had measurable LNAPL in any of the site wells, and a dedicated water level
measuring device will be installed during the second quarter 2000 sampling event to
reduce the possibility of cross-contamination. The dedicated device will be used for
water level data during subsequent sampling events, but a manual water level meter
should be available as backup equipment.)
9. Prepare the dedicated purging and sampling equipment for installation or use. If
installation of the dedicated equipment is necessary (initial sample event), organize
the equipment on the plastic sheeting. Make certain the equipment remains clean of
debris and contamination. When ready, install the equipment per manufacturer
•
instructions and specifications. The low-flow pump will be slowly lowered into the
well until it reaches the mid-screen depth, and the pump will be at least two feet
above the bottom of the well to prevent disturbance of sediment which may be
located in the well bottom. The pump will be securely attached to the wellhead.
Refer to the manufacturer's literature and installation/connection instructions for any
required information.
10. Make all necessary connections to operate the low-flow purging and sampling
equipment. Refer to the manufacturer's user information or operating instructions
if necessary.
11. Confirm the depth to water once again prior to pumping. Initiate pumping at
approximately 200 to 500 milliliters (mL) per minute. The pump will cause very
little or no water level drawdown in the well (less than 0.3 feet), and the water level
will stabilize. Monitor the water level with the dedicated sensor and equipment
during pumping. Do not allow pump suction to cease or entrainment of air to occur.
Record any adjustments to the pumping rate and the corresponding water level. If
necessary, pumping rates may be reduced to the minimum capabilities of the pump
to avoid pumping the well dry and/or to ensure indicator parameters stabilize. In the
event the recharge rate of the well is very low, interrupt purging, but do not allow
drawdown within the well to be below the pump intake depth. Maintain a steady
flow rate to the extent possible, and record the preferred pumping rate for each well
in the field notebook and sampling log for future reference. Sampling of wells with
very low recharge rates may commence when the volume of water in the well has
sufficiently recovered to permit sample collection.
12. Monitor the indicator parameters during well purging with the equipment available
for this purpose. Parameter measurements will be collected every three to five
minutes ( or as appropriate). The well is considered stabilized and ready for sample
collection when the indicator parameters are within the following ranges of
deviation:
• Dissolved oxygen (DO) -+/-0.1 milligrams per liter (mg/L)
• Specific conductivity -+/-3% of full scale
• pH -+/-0.1 pH units
• Temperature -+/-0.2 degrees Celsius (°C)
• Reduction/oxidation (ORP or redox) potential -+/-3% of full scale
Puls et al. (1991 and 1992) demonstrated the following: 1) specific conductance, pH,
and temperature were the least sensitive indicators of aquifer equilibration; 2) redox
potential, dissolved oxygen, and constituent concentration were more sensitive
indicators of equilibrated conditions; and 3) turbidity was the most sensitive indicator
of aquifer equilibration.
Measurements of DO and ORP must be collected using a closed flow-through cell.
•
Other parameters may be collected in a clean container (jar, beaker, etc.) or in a flow-
through cell if available equipment is able to do so. All indicator parameter
measuring equipment will be calibrated according to its respective manufacturer's
recommendations and schedules. In addition, the DO meter will be calibrated using
a two point calibration method with a sodium sulfite solution as the zero DO
reference. The ORP meter will be calibrated using Zobells solution.
13. Upon stabilization of the field indicator parameters, collect the required groundwater
samples. (NOTE: Total purge time is expected to be at least 30 minutes, but no more
than 90 minutes.) Fill the sample containers immediately from the sample device
discharge point, minimizing any contact with the atmosphere. The order of sample
collection will be as stated below:
• Volatile organic compounds
• Semi-volatile compounds
• Metals
Samples for VOCs will not contain any bubbles or vapor headspace in the container.
14. Complete the sample labels with the sample time and date, and cover the labels with
clear pack tape to secure them onto the sample container.
15. Secure filled sample container in packing material (e.g., bubble wrap), and store at
0°C to 4 °Con wet ice in an insulated cooler.
16. Continue pumping from the well after all sample containers have been filled.
Measurements of the indicator parameters and visual observations of the pumped
groundwater will be recorded in the field notebook and on the sampling log.
17. Disconnect surface equipment from the dedicated downhole components, and
confirm all non-dedicated equipment is accounted for and removed from the well.
Replace the well cap(s) and lock the well. Use a new lock if cutting of the old lock
was required.
18. Record in the field notebook and on the sampling log the time that sample collection
activities were completed.
19. Clean all non-dedicated gauging and sampling equipment before moving to the next
well to be sampled.
20. Put all of the used disposable sampling materials (e.g., plastic sheeting, gloves, etc.)
in appropriately labeled containers, and proceed to the next well. Repeat Steps 1
through 21 chronologically .until all wells have been purged and sampled.
21. Complete the chain-of-custody, packing, and shipping procedures.

Dear Ms. Bennett:
• GE lighting Systems
This letter is in response to the US EPA July 29, 1999 request for two test pits in the
unexcavated portion of Landfill B. The attached memo from HSI Geotrans documents
clarifications that were made during our July 30 onsite meeting.
GE will proceed according to the attached memo unless we hear otherwise from EPA by
noon on Tuesday, August 3, 1999. We hope to resolve this matter as quickly as
possible.

MEMORANDUM
TO: Janet Boyer, GE Lighting Systems
FROM: Todd Hagemeyer, HSI Geo Trans, Inc. ~
DATE: July 30, 1999
SUBJECT: EPA's Request for Test Trench at Landfill B
HSI Geo Trans Project No. N754-026
EPA requested test trenching to be performed in the Landfill B area in a
letter to GE dated July 29, 1999. During a site meeting today, EPA verbally
provided some clarification on their request. This memorandum summarizes that
clarification.
EPA has requested two test trenches. The location and size of the
requested test trenches are shown on Figure I. If no capacitors are found during
test trench excavation, one composite soil sample is to be collected from soil
removed from each test excavation. The soil samples are to be analyzed for PCBs
and compared to the project performance standard of 10 ppm total PCB. If the
soil meets the performance standard, it may be returned to the test pits, even if it
contains construction debris including bricks and concrete.

Dear Ms. Boyer:
In accordance with Section VI, paragraph 14 of the Consent Decree (CD), the
U.S. Environmental Protection Agency (EPA) hereby requests that GE install two test
pits in the western portion (unexcavated) of Landfill B to determine if all PCB
contaminated soil and debris above 10 ppm has been removed. The locations of the
test pits will be determined in the field.
Landfill B was estimated to be 0.14 acres in area with a maximum depth of eight
(8) feet in the Remedial Design (RD). It is apparent from the remediation currently
taking place in Landfill B that both the Remedial Investigation (RI) and the pre-RD
(sampling and geophysical) did a poor job in identifying the extent of contamination.
Landfill B was found to contain an unexpectedly large amount of capacitors and PCB
contaminated soil, along with the known construction debris.
EPA and the State are concerned that additional contamination may exist in the
area thought to be clear of contamination. GE's contractor, HSI Geo Trans seems
convinced that there are no capacitors and no PCB contamination in this area. The
test pits would bring a resolution to this matter and could be completed in a matter of
hours. Test pits have been used during this remediation of Landfill Bin other areas to
determine extent.
This issue must be resolved before cap installation begins because if additional
contamination needs to be removed, it can then be placed in the dry sludge
impoundment (OSI) along with the other material from this entire remediation process.

remedial action. If you have any questions, please give me a call at 404/562-8824.
