1.0 INTRODUCTION
In letters dated July 27, 1992, and August 27, 1992, U.S. EPA requested that the
Respondents for the Yeoman Creek and Edwards' Field Landfills prepare an addendum
to the RI/FS Work Plan for additional landfill gas monitoring to determine the extent oflandfill gas migration from the Site. The letters indicated that the additional monitoring
should be conducted on the northern, western and eastern sides of the Yeoman Creek
Landfill portion of the Site and on the western and southern sides of the Edwards' Field
Landfill portion of the Site. This monitoring should be conducted by completingadditional soil gas measurements progressively farther from the Site outside perimeter gas
probes where elevated screening readings were obtained on the combustible gas indicatoror organic vapor analyzer. In addition, the addendum should include a schedule and
revisions to the U.S. EPA-approved Field Sampling Plan (FSP), Quality Assurance Project
Plan (QAPP), Health and Safety Plan (HSP) and Endangerment Assessment Plan, asnecessary.
An Additional Landfill Gas Monitoring addendum was submitted to the agencies onSeptember 29, 1992 and comments were received in a letter from the U.S. EPA dated
November 19, 1992. A response to comments was prepared by Colder Associates andsubmitted in a letter dated December 4,1992. This revised addendum addresses agencycomments and approved modifications presented in the December 4, 1992 letter.
Procedures to perform additional soil gas measurements that are described in thisaddendum are planned to be implemented in the area south of the non-contiguous waste
area at the Edwards' Field Landfill and at locations outside selected existing perimeter gasprobes at the Yeoman Creek and Edwards' Field Landfills.

2.0 FIELD PROCEDURES FOR INSTALLATION AND SCREENING OF TEMPORARYSOIL GAS PROBES
The field program will involve the installation of temporary soil gas probes and Level 1
field screening analysis of soil gas using portable field instruments, including a
Combustible Gas Indicator (CGI) and a photoionization detector (FID). These instruments
will allow measurements of methane, H2S and volatile organic compounds (VOCs).
Screening is planned to be conducted in the winter when at least the first two inches ofground is frozen, if possible, and during a period of stable barometric pressure. The
barometric pressure will be monitored during the investigation and if a drop at a rate inexcess of 5 mb/hour (i.e., 0.15 inches of mercury/hour) is observed work will be
temporarily delayed until the barometric pressure stabilizes. Screening will be conductedat a minimum, in temporary soil gas probes located outside existing perimeter gas probeswhere readings greater than 5 percent of the LEL were obtained on the CGI during thetwo landfill gas probe screenings conducted in June and September, 1992. Data from the
landfill gas probes during these screenings are summarized on Tables 1 and 2. If resultsof the upcoming third round of gas probe screening indicate that additional existing
perimeter probes show CGI readings above 5 percent LEL, temporary probes will also be
installed at these locations.
At existing perimeter probe locations selected for investigation, temporary probes will beinstalled at progressively greater distances from waste along transects oriented
perpendicularly to the edge of waste until non-detect CGI readings (i.e., less than or equal
to 3 percent LEL) are obtained in two consecutive probes. The locations of landfill gasprobes that have exceeded the 5 percent LEL criterion and the proposed transects from
these probes are shown on Figure I. The initial temporary probe in each transect will be
within 10 feet of the edge of waste or an existing gas probe which has shown thepresence of landfill gas (i.e., greater than 5 percent LEL), unless physical obstructions or
buried utilities are present (a commercial utility survey will be conducted prior toinstallation of any probes). The spacing of subsequent probes in each transect will be 50feet unless specific site conditions (i.e. presence of physical obstructions or utilities)
prohibit the installation of a probe. If a probe cannot be installed at the 50 foot distance,the closest alternative location will be selected. The two perimeter gas probes, LFG-222

January 1993 -3- 913-8083.205/913-8084.205
and LFG-218, along the east and west sides of the Lovinger property at the YeomanCreek Landfill both show gas screening levels above the 5 percent LEL criterion. Sinceexisting site information indicates that gas is present east of this property, a transect is notincluded eastward from LFG-222. Instead, an alternate transect is planned northward(Figure 1) from the Lovinger property where there is currently no information.
Temporary probes will be installed at locations between perimeter gas probes in which5 percent LEL criterion has been exceeded and buildings located within 150 feet of theperimeter probes, unless landfill gas was also detected in the basement/erawlspace of thebuilding, or the building does not have a basement/era wlspace. If landfill gas has beendetected in the basement of the building, it is assumed that gas is present around thebuilding, and therefore, the temporary probes will be placed at 50 foot intervals on theopposite side of the building progressively further from the landfill until non-detect CGIreadings are obtained in two consecutive probes. The locations of these proposedtransects are also shown on Figure 1. No temporary probes will be placed around
buildings with basements if screening of intervening temporary probes shows that gashas not reached the building or the building has a sump with perimeter drains andscreening shows that gas is not entering through the tiles.
The equipment and procedures that will be used to install the temporary probes andcomplete the screening and the field procedures that will be employed are described inthe following sections.
2.1 Equipment and Materials
Equipment and materials required to conduct soil gas screening in the temporary probesshall include the following items:
Stakes and colored flagging;• Temporary steel gas probe(s);• Soil gas sampling and calibration ted la r bags;• Hammer for installation of probes. Depending on site conditions, a rotary
impact drill and 5/8 inch x 24 inch drill may be required for drilling a pilothole for installation of the temporary soil gas probe;
Golder Associates
January 1993 -4- 913-8083.205/913-8084.205
• Bentonite chips and potable water;• Barometer;• Decontamination water (i.e., commercially available distilled water for
decontamination of the soil gas probes);
• Reagent grade methanol for decontamination of the soil gas probes;• Alconox (or other equivalent, anionic, biodegradable detergent) for
decontamination of the soil gas probes;• Field documentation and support equipment, including sprayers, towels,
plastic bags, buckets, waste containers, and tools for decontamination andprobe assembly/disassembly;
• A peristaltic pump for purging the soil gas probes;
• Mechanical jack for removing the sampling probes from the access holes;
• Portable instruments for gas screening: CGI and PID;• Calibration gases for field screening instruments;
• Tape and compass; and• Materials needed to repair holes in asphalt or concrete.
2.2 Temporary Probe Installation
The installation of a temporary gas probe will typically involve the following sequence ofactivities:
Step 1: Assemble the sampling probe by first taping all fittings with non-adhesiveteflon tape (Note: the sampling probe must be completely decontaminatedprior to assembly according to the procedures outlined in Step 2 in Section2.4). Assemble one 5-foot section.
Step 2: If the surface at the sampling location is pavement or coarse fill, providean access hole for inserting the sampling probe by drilling a two foot deep,5/8 inch diameter hole at the sampling point with a rotary impact hammerand drill. Alternately, provide an access hole by driving a 5/8 inch solidsteel pilot probe to within 1 foot of the target sampling depth (typically 4feet).
Step 3: Place a removable steel drive point in the end of the temporary gas probeassembly.
Step 4: Drive the probe into the ground or into the access hole to a depth of 4feet, attach the removal jack to the probe and lift the probe out of theaccess hole about 1/2 inch to separate the probe tip from the end of theprobe and allow the soil gas to enter.

January 1993 -5- 913-8083.205/913-8084.205
Step 5: Seal the top of the annulus between the probe and the formation withhydrated bentonite chips.
If a portable generator is required, it will be positioned away from the immediate workingarea in a downwind direction from any sampling or analytical support activities. Also,
activities involving flammable or ignitable materials/vapors will be conducted at least 50
feet away from the generator. The generator will be positioned in a well ventilated area
and necessary precautions will be taken to avoid electrical shock.
2.3 Procedures for Gas Screening
The procedure for field screening using the portable instruments will include the
following steps: , ,
Step 1: Connect the peristaltic pump to the top of the installed probe and pumpuntil a minimum of 3 probe volumes has been removed, if possible.Purging details, including date, time and volume purged, shall be recordedin the field logbook.
Step 2: Record the barometric pressure.
Step 3: Attach an evacuated sampling tedlar bag to the exhaust of the pump.Open the valve to allow soil gas to enter the bag. Close the valve andremove the bag. Collect a duplicate once per day, at a minimum. Also,collect a minimum of one equipment blank (i.e. fill a tedlar bag bypumping through a decontaminated probe) and one ambient air blank (i.e.fill a tedlar bag with air using the pump) per day.
Step 4: Connect the filled tedlar bag containing the soil gas sample to thecalibrated CGI in scan mode and open the valve. Record the % LEL, %O2, """'and ppm H2S readings as the instrument scans. Close the valve andremove the bag.
Step 5: Connect the tedlar bag sample to the calibrated PID and open the valve.Record the stabilized and any peak instrument readings in ppm. Close thevalve and remove the bag.
The same analytical procedures will be followed for all samples including duplicates and
blanks. Maintenance, calibration and recaltbration of the field instruments shall beconducted according to the procedures and schedules provided in the approved RI/FS
Work Plan (FSP and QAPP) that are applicable to gas probe screening.

January 1993 -6- 913-8083.205/913-8084.205
2.4 Temporary Probe Removal and Decontamination
Step 1: Remove the soil probe from the access hole with the mechanical jack andplug the hole with bentonite. Stake or mark the hole for a subsequenttape and compass survey.
Step 2: Once the probe is removed from the hole, it must be decontaminated priorto use at another location. The procedure for decontamination is asfollows:
Remove all teflon tape from the probe threads.
Remove soil particles from the interior of the probe with a narrowwire brush.
Rinse the probe exterior and interior with a solution of alconox anddecontamination water, scrubbing the interior and exterior withbrushes.
Rinse with decontamination water.
Rinse with reagent-grade methanol and finally withdecontamination water.
Allow the equipment to air dry. Immediately cover the probe endsand shaft with plastic to minimize the possibility of contamination.Once the probes are decontaminated, additional sampling maycontinue as described above.
2.5 Records
Soil gas screening activities shall be documented chronologically in bound logbooks. One
set of logbooks shall be dedicated to sample acquisition and onsite activity monitoring/
and shall provide a chronological record of onsite activities. Other supporting records
shall be retained in a temporary working file. Logbook entries shall be signed and dated
at the end of each day's activity, or upon transfer of logging responsibilities to otherpersonnel.

2,6 Health and Safety
The health and safety provisions for gas probe activities that are included in the approved
RI/FS Work Plan will be applicable during the installation and screening of the temporary
probes. In addition, the Field Manager shall conduct a daily briefing for project
personnel on site. The meeting shall address the proposed scope of the day's activities -
location, number, and type of samples to be taken; specific personnel assignments - andshall include a review of pertinent health and safety considerations.

3.0 SCHEDULE
Performance of the planned soil gas measurements at the Yeoman Creek and Edwards'
Field Landfills will begin after agency approval of this revised work plan addendum tocoincide to the extent possible, a period when the first 2 inches of ground at the site isfrozen and the barometric pressure is stable. It is currently anticipated that these
activities will be completed by the end of February, 1993 providing that significant delaysare not encountered due to property access difficulties.
