EXECUTIVE ST]MMARY
Maxim Technologies, Inc. was requested to conduct a remedial feasibility study concerning the
Big-O Tire facility in Richfield, Utah. A subsurface investigation at the site was conducted by
the Utah Division of Environmental Response and Remediation (DERR) in December of 1993.
Quarterly groundwater monitoring has been conducted at the site by Maxim since August of
1995. Data from these investigations indicate that soil contaminated with petroleum
hydrocarbons above the DERR Tier 1 Screening kvels extends up to 260 feet downgradient to
the southeast of the source area. Groundwater contaminated above the Tier 1 levels for benzene
extends up to 190 feet downgradient of the source area.
Soil contamination appears to be limited to the zone between six- to eleven-foot below ground
surface Og9. Using a vertical contamination thickness of five feet, the estimated total volume
of soil impacted above the DERR Tier 1 Screening trvels is approximately 2,600 cubic yards
(yd'). This volume includes approximately 1,730 yd3 located under U.S. Highway 89 is
inaccessible to excavation or trenching. Approximately 870 yd3 of soil impacted above the Tier
1 levels are located to the west of U.S.Highway 89. Due to engineering constraints (buildings,
sidewalks, utilities), only 530 yd3 is accessible to excavating. Approximately 1,030 yd3 of clean
overburden soil overlies this area.
Several remedial technologies were reviewed for possible application at the Big-O Tire facility.
These technologies include: 1) excavation and disposal; 2) horizontal groundwater air sparging
in conjunction with soil vapor extraction; and 3) passive oxygen release in conjunction with soil
vapor extraction. Descriptions, costs, and advantages and disadvantages for each technology
were presented. Approximately 20 to 30 percent of the contaminant soil and groundwater
plumes are accessible to active remedial technologies due to engineering constraints.
?
1.0 INTRODUCTION
Maxim Technologies, Inc. was requested to conduct a remedial feasibility study concerning the
Big-O Tire facility for the Utah Division of Environmental Response and Remediation (DERR).
Big-O Tire is located at2}8 South Main Street in Richfield, Utah. The Big-O Tire facility and
the most recent groundwater flow direction are shown in Figure 1. The site is assigned Facility
Identification #2000326 and Release Site EHLR by DERR.
A subsurface investigation of the site was conducted by the DERR in December of 1993.
Quarterly groundwater monitoring has been conducted by Maxim since August of 1995. Using
the characterization data, Maxim has prepared the following Remedial Feasibility Study Report.
2.0 BACKGROI]ND INFORMATION
Evidence of a releases of petroleum hydrocarbons from underground storage tanks (USTs) at the
Big-O Tire facility were discovered during UST removal activities in March 1992. Two 500-
gallon used-oil USTs and one 4,000-ga11on UST were removed from an excavation located on
the eastern portion of the site as shown in Figures 2 and 3. Two 10,000-ga11on diesel USTs and
one 6,000-gallon gasoline UST were removed from an excavation located on the western portion
of the site. One 6,000-gallon gasoline UST was closed in-place near the west excavation.
Free-phase petroleum product was encountered during the UST closures in both excavations.
Contaminated soil was removed from the west excavation until further excavating was not
feasible due to proximity of the building. Over excavation of contaminated soil was limited
from the east excavation due to proximity of utilities and U.S. Highway 89.
Subsequent investigations performed by DERR includes installation of nine groundwater monitor
wells and 11 soil borings. Quarterly groundwater monitoring has been conducted by Maxim
since August 1995. Tables 1 and 2 present summaries of the soil and groundwater analytical
data collected from the site. These data indicate that soil contaminated above the DERR Tier
I Screening Irvels for benzene exists up to 260 feet downgradient to the southeast of the source
area, as shown in Figure 3. Groundwater contaminated above the Tier I levels for benzene
exists beyond 190 feet downgradient of the source area, as shown in Figure 4.
Concentrations of benzene, naphthalene, and total petroleum hydrocarbon (TPH) in soil are
greatest in the area to the east of the facility building near monitor wells B-5 and B-7.
Concentrations of benzene and naphthalene in groundwater are greatest near wells B-5, B-7, and
B-9. Contaminants in groundwater appear to be attenuating, however, contaminant
concentrations continue to fluctuate seasonally.
v
3.0 FEASIBILITY STTJDY
3.1 AFFECTED AREA
Site investigations and groundwater monitoring to date indicates moderate to high concentrations
of petroleum hydrocarbons in both soil and groundwater throughout the eastern portion of the
site and migrating off-site toward the southeast. Soil contamination appears to be contained
within the six-to eleven-foot depths. Using a vertical contamination thickness of five feet, the
estimated total volume of soil impacted above the DERR Tier I Screening Irvels is
approximately 2,600 cubic yards (yd'). This volume includes approximately 1 ,730 yd3located
under U.S. Highway 89, which is inaccessible to excavation or trenching. Approximately 3,100
yd3 of clean overburden soil overlies the contaminated material. Calculations for the volume of
contaminated soil are included as Attachment A.
Approximately 870 yd3 of soil impacted above the Tier I levels is located to the west of U.S.
ffigfrway 89. Due io engineeringconstraints (buildings, sidewalks, utilities), only 530 yd3 of
contaminated soil are accessible to excavating. Approximately 1,030 yd3 of clean overburden
soil overlies this area.
REMEDIAL ACTION COST ANALYSIS
The following discussion reviews the various technology alternatives and associated costs for
potential remedial action at the site. Technologies reviewed include:
. soil excavation/groundwater removal and disposal;
. horizontal groundwater air sparging/soil vapor extraction;
. passive oxygen release/soil vapor extraction.
Capital costs include implementation or equipment purchase and installation of the remedial
action. Associated costs include operation/maintenance and monitoring costs for an estimated
two-year period. Costs are estimated for the purpose of this study and are based on anticipated
quantities and vendor quotes.
3.2.1 SoiI Excavation/Groundwater Removal and Disposal
Brief Description: Excavate and dispose of contaminated soil that is accessible to excavation
(excluding soil under buildings or roadways) as shown in Figure 5.
Remove and dispose of contaminated groundwater associated with
excavation activities at advanced Petroleum Recycling. Dispose of
contaminated soil at Sevier County Landflll.
v

Advantages:o rapid completion of remedial activities
removes large portion of highly contaminated soil (i.e., removal
of continuing groundwater contaminant source)
increased soil disposal costs due to saturated condition
contaminated soil disposed at landfill presents continuing liability
only abov/2)-{ercent of contaminated soil accessible to excavation
due to engineering constraints of the facility building, adjacent
sidewalk and utilities, and U.S.Highway 89
Effectiveness: . can only remove approxim ately 20 percent of contaminated soil
addresses portion of groundwater contaminant source, but does not
address contaminated groundwater effectively
Capitol costs: $57,000 - total

costs for excavation/disposal/backfill and
approximately 1,000 gallons de-watering
Associated costs: $30,000 - (monitoring)

4.0 CONCLUSIONS AND RECOMMENDATIONS
Investigation and monitoring data collected at the Big-O Tire facility indicates moderate to high
concentrations of petroleum hydrocarbons in both soil and groundwater throughout the eastern
portion of the site and migrating off-site toward the southeast. Using a vertical contamination
thickness of five feet, the estimated total volume of soil impacted above the DERR Tier I
Screening I-evels is approximately 2,600 cubic yards (yd'). This volume includes approximately
1,730 yd3 located under U.S. Highway 89, which is inaccessible to excavation or trenching.
Approximately 870 yd3 of soil impacted above the Tier I levels is located to the west of U.S.
Highway 89. Due to engineering constraints (buildings, sidewalks, utilities), only 530 yd3 of
contaminated soil are accessible to excavating. Approximately 1,030 yd3 of clean overburden
soil overlies this area.
The following recommendations are made for the Big-O Tire site:
