depths between 10 and 15 feet. Proposed locations for the soil borings are shown
in Figure 1. Additional borings may be drilled based upon findings of the initial
field screening samples. One soil sample at eight feet (ust above the water tabte)
will be collected from each boring during the investigation.
o Soil samples will be screened for the presence of hydrocarbon vapors using a
Foxboro OVM-128 flame ionization detector (FID) and a detector tube and wash
bottle. A measured amount of soil will be paced in the wash bottle with a defined
volume of water. Air will be sparged through the water/soil mixture in the wash
bottle to strip out the volatile hydrocarbons, which will be measured with the
detector tube. Four of the soil samples will be submitted for total petroleum
hydrocarbons (TPH) and benzene, toluene, ethylbenzene, total xylenes, and
naphthalene (BTEXN) by EPA methods 8015 modified and 8020, respectively.
o The eight borings, described above, will be completed as eight groundwater and
soil-gas sampling wells. The soil-boring field-screening results will be used to
determine the monitor/sampling well locations. The groundwater and soil-gas
sampling wells will be screened across the static groundwater level so they can
be used as both groundwater monitoring wells and soil-gas sampling points. The
two-inch diameter monitoring wells will be installed to depths of approximately
L4 feet below ground surface (bgs) and will consist of 10 feet of 0.02 slot screen
in a sand pack with a three-foot bentonite seal at the surface. The well/sampling
point locations will be identified in the field in consultation with rhe DERR
project manager. Proposed locations for the monitor wells/sampling points are
shown in Figure 1. The wells will be developed by pumping and surging.
o Maxim Technologies, Inc. (Huntingdon) will contact Blue Stakes and other
appropriate utility companies to mark underground utilities prior to
corlmencement of field activities. The soil boring, well installation, and well
development will be performed by RC Drilling.
Perform one quarterly groundwater sampling at the site:
. After development, groundwater samples will be obtained from six selected new
groundwater wells. The samples will be submitted for laboratory analysis of total
petroleum hydrocarbons (TPH) and benzene, toluene, ethylbenzene, total xylenes,
and naphthalene @TEXN) by EPA methods 8015 modified and 602, respectively.

o One quarterly groundwater sample will be collected from each of the nine
previously installed monitor wells (B-1 through B-11) using proper sampling
protocol pursuant to Utah Administrative Code R31l-205 (1992). These
groundwater samples will be submitted for laboratory analysis of TPH and
BTEXN. Data from two downgradient wells (MW-l and MW-2) at the 7-11
station at 300 South and Main will be included in the Big-O data set. These wells
are shown in Figure 1. For the cost estimate, it is assumed that these samples
will be collected and submitted for analysis by Maxim.
Develop a corrective action plan feasibility study for the site:
o Evaluate the potential use of groundwater air-stripping trench, soil-vapor
extraction (SVE), and/or bioremediation to remove petroleum hydrocarbons from
soil and groundwater. A preliminary indication of the extent of contamination in
groundwater is shown in Figure 2.
o Field pilot tests for an insitu groundwater air-stripping trench and a horizontal
soil-vapor extraction (SVE) system will be performed on-site to determine
effectiveness of these technologies at the site.
o Slug tests witl be performed on two of the monitor wells (B-5 and B-11) to obtain
aquifer parameter information.
The in situ groundwater air-stripping trench pilot tests will involve installation of
one horizontal sparge line placed in a trench which is dug to a depth of 12 feetbgs. The horizontal sparge line will be constructed of two-inch diameter
perforated or porous plastic pipe. The sparge line will be located at a depth of
11.5 feet or approximately two to three feet below the water table. The trench
will be filled with washed pea gravel. A horizontal vacuum-extraction line will
be placed in the same trench above the sparge line as shown in Figure 3. The
extraction line will be installed 7.5 feet above the sparge line and 4.5 to 5.5 feet
above the water table. The vapor-extraction line will be constructed of 2"
diameter SCH-40 PVC screen. The vapor extraction line will be placed at a
depth of four feet bgs, with one foot of gravel will be placed above the extraction
line. An impermeable liner will be placed above the gravel in a keyed trench and
backfilled with excavated material to seal the header from atmospheric leakage
as shown in Figure 3.
The air-stripping trench will be excavated by Robinson Transport of Salina, Utah.
The objectives of the insitu air-stripping trench is 1) to treat groundwater flowing
through the trench by sparging volatile organics (i.e., BTEX) from the
N : lC h arw i nD E RRIB i g O. I nv
groundwater, while it is contained in the trench and 2) to increase dissolved
oxygen in the groundwater down-gradient of the trench.
Three soil-gas/groundwater monitor points will be placed at distances of
approximately five, 15, and 25 feet laterally away from the trench as shown in
Figure 1 (these three wells are included in the eight listed above). Monitor wells
B-3 and B-4 will also be used as monitoring points located 10 and 50 feet from
the trench. Figure 1 shows a plan view of the pilot test layout. Figure 3 presents
construction details of the sparge and vapor extraction lines and monitoring
points.
For the SVE pilot operation, the upper horizontal SVE line will be evacuated and
monitor wells (B-5 and B-7) and the soil-gas/groundwater monitoring points will
be used to monitor the vacuum effects of the SVE in the soil. The SVE pilot test
will involve inducing a vacuum on the vapor extraction header using a
regenerative blower rated at L27 scfm and 65-inches water gauge. The pilot tests
will be run at flow rates of 40, 65, and 90 scfm. Changes in induced vacuum
will be recorded at each monitoring point during each flow-rate test. The
hydrocarbon vapor content will be monitored at the vacuum pump effluent for
each flow-rate test. The vacuum change versus distance from the header to each
monitor point will be evaluated to determine the lateral influence for effective soil
vapor extraction at the site.
The air-stripping trench pilot test, which includes both sparging and SVE, will
involve injecting air from a compressor into the horizontal sparge line at
approximately five pounds per square inch (psi) at flow rates of I0,20, and 40
standard cubic feet per minute (scfm). The SVE line will be operated at
approximately 10 scfm greater than the sparging flow, or 20,30, and 50 scfm.
changes in water level, induced pressure, dissolved oxygen, and hydrocarbon
vapor content will be recorded at each monitor point during each flow rate test.
These parameters will be evaluated to determine the effect of the air-stripping
outside the trench.
The estimated groundwater flow velocity at the site is about 0.03 feet/day for a
groundwater gradient of 0.01 ft/ft. At this groundwater flow velocity,
groundwater would require over five months to travel five feet to the nearest
monitor point. However, the sparging action in the trench will increase the
groundwater level in the trench raising the groundwater flow from the trench.
A piezometer will be placed in the trench to measure the groundwater level in the
stripping trench.

Soil and groundwater samples will be collected and arnlyzed to assess the
potential for bioremediation at the site. Soil and groundwater samples will be
collected from three areas at the site to evaluate site soil and groundwater
chemistry. The samples will be collected from an upgradient area with no TPH
contamination, an area of high contamination, and an area down-gradient of the
contamination plume. Table 1 lists the parameters for soil and groundwater that
will be analyzed.
Soil and groundwater samples will be ar:,a,lyzed for physical, chemical, and
bioremediation parameters at four separate laboratories. Soil and groundwater
samples will be submitted to American West Analytical I-aboratory in Salt Lake
City for chemical analysis other than TPH and BTEXN (see Table 1). The
TPH/BTEXN analyses will be performed by Utility Testing [aboratory. Soil
samples will be atalyzed for site-specific physical parameters at the Maxim
Technologies, Inc. (Huntingdon) soil laboratory in North Salt Iake. Groundwater
samples will be analyzed for biological parameters at the Richards Laboratory in
Pleasant Grove, Utah.
o Laboratory analytical costs for TPH/BTEXN analyses are approximately $76.50
per sample for soil or groundwater. I"aboratory analytical costs for
bioremediation purposes are approximately $192.00 for soil analysis, $130.00 for
groundwater chemistry, and $60.00 for biological parameters.
Determine the effectiveness of the in situ groundwater air-stripping trench:
o After initially testing the groundwater air-stripping trench determine the air-
stripping trench effectiveness by operating the system for one month. Following
the demonstration test the groundwater in wells B-4, B-5, B-7 and the three soil-
gas/groundwater monitor points will be sampled and analyzed for BTEXN and
TPH. Dissolved oxygen and microbial colonies will measure in the groundwater
sample.
o The off-gas from the in situ stripping trench will be sampled and analyzed for
BTEX and TPH. Required air-quality permits for the demonstration test will be
obtained.
Prepare and submit a report on the additional investigations
o The additional investigations report will describe the CAP feasibitity study and
the stripping trench effectiveness demonstration.

Work Assignment Amendment #EHLR-2.A for three additional quarters of groundwater
monitoring at Big-O Tire, 208 S. Main, Richfield, Utah
Facility I.if@fDlelease Site EHLR.
Dear Mr. Chatwin:
The Division of Environmental Response and Remediation (DERR) has completed its review of
Maxim's request for a Work Assignment Amendment to Work Assignment Number EHLR-2 under
contract #95-1024, due to the need for obtaining three additional quarters of groundwater monitoring data.
These changes were necessary due to the implementation of a Corrective Action Plan (CAP) feasibility
study at a nearby site and the need for additional groundwater data at Big-O Tire.
The enclosed Work Assignment Amendment # EHLR-2.A hereby formally approves a change in
the scope of work, and a corresponding increase in the approved budget with an additional amended cost
of $8,430.18. The amended total approved budget is now $11,240.24. If you have any questions
concerning the Work Assignment Amendment #EHLR-2.A, please call Kate Johnson, the DERR Project
Manager, at (801) 536-4100.

WORK ASSIGI{MENT AMENDMENT # EHLR.2.A
95-t024
Change in Scope of Work at Big-O Tire
208 South Main, Richfield, Utah
The contractor (Maxim) is requested to complete the following items as Work Assignment Amendment #
EHLR-2.A. These changes were necessary due to the need to monitor groundwater conditions while a CAP
feasibility study is underway at Grand Western Gas and Groceries. The results of the CAP feasibility Study,
combined with the results of the groundwater monitoring at Big-O, will be used to decide the direction of
corrective action at Big-O.
The following changes are hereby made to Work Assignment # EHLR-2, which was originally approved by
the DERR on August 8, 1995 and mailed on August 8, 1995.
1. Three additional quarters of gtoundwater monitoring.
Justification: The original approval of one quarter was insufficient for the scope of work presented by the
site.
Amended Budget: $2,810.06 per quarter for three quarters. Total amended budget is $11,240.24.
