EA Engineering, Science, and Technology I. REPORTSUNUdARY The following report describes the activities and findings of EA Engineering, Science, and Technology, Inc. at Exxon Retail
Station 6-0275,4191 Belt Line Road @Midway Road, Addison (Dallas County), Texas. The scope of work, authorized under ExxonMobilEnvironmental Work Release 21044479 included the installation
of two groundwater monitor wells, collection and laboratory analysis of soil and groundwater samples, and investigati ve research of surrounding geology, hydrogeology, and potential
receptors. The primary objectives of the investigation were: a) To detennine if gasoline related hydrocarbons are present in soil or groundwater at the Exxon retail station. b) To establish
groundwater flow direction. . Groundwater monitor well (MW) installation at Exxon 6-0275 began on November 9,2001 when EA cleared each well location of utilities using vacuum excavation.
The monitor well locations were selected using ExxonMobil protocol and a topographic map. MW-MW-10 was installed at the southwestern side of the site, west of the tankpit and southwest
of the dispenser islands. MW-ll was installed at the northern side of the site, north of the tank pit and northeast of the dispenser islands. Soil sampling was performed while the monitoring
wells were being cleared and installed. Soil samples were collected from MW-1O at the 0' to 2',2' to 4' and 10'-15' intervals for laboratory analyses. Soil samples were collected from
MW-11 at the 0' to 2', 3' to 6' and 10'-15' intervals for laboratory analyses. Two groundwatermonitoring wells installed during the former LPSTcase activities (MW-3 and MW-4) were also used to complete this divestment assessment. MW-10 and MW-11 were installed to total depths
of 15 feet. Groundwater did significantly accumulate MW-11 within two hours after installation; however, MW-I0 was dry. MW-1O and MW-ll were completed with 2.5 feet of solid two-inch
diameter PVC riser. The remainder of all wells were completed with factory slotted PVC screen. screen. Soil samples were analyzed for benzene, toluene, ethyl benzene, and xylenes (BTEX),
total petroleum hydrocarbons (TPH) and methyl tertiary butyl ether (MTBE). Laboratory analyses indicated total BTEX concentrations ranging from <1.0 l1g/Kg to 204.3 l1g/Kg in the sample
intervals that were analyzed. MTBE concentrations ranged from <111g/Kg to 100 l1g/Kg in the sample intervals that were analyzed. TPH concentrations were not detected in any soil samples
analyzed. None of the soil samples collected during this assessment displayed BTEX or TPH concentrations that exceeded TNRCC soil action/screening levels (TNRCC-0621 (8-6-96), Release
Detennination Report Form). No action level for MTBE has been established by the TNRCC. Laboratory analyses for soil samples are summarized in Table 1. Divestment Assessment 1-1 
EA Engineering, Science, and Technology On November 16,2001 groundwater samples were collected for laboratory analyses from MW-lO and MW-11 and sentinel wells MW-3 and MW-4. Laboratory
analyses indicated total BTEX concentrations ranging from <1.0 Ilg/Kg in MW-4 to 1,522 Ilg/Kg in MW-11. TPH concentrations were not detected in any water samples analyzed with the exception
of MW-U, at a concentration of 6.8 mg/Kg, MTBE concentrations ranged from L21lg/Kg in MW-4 to 43,000 Ilg/Kg in MW-Il. No action level for MTBE has been established by the TNRCC. Hydrocarbon
concentrations in groundwater samples collected from MW-4 and MW-10 were below TNRCC action levels for groundwater (TNRCC 0621 (8-6-96), Release Detennination Report Form). The groundwater
samples collected from MW-3 and MW-ll were above TNRCC groundwater action levels for benzene. The groundwater sample collected from MW-11 was also above TNRCC groundwater screening levels
for TPH. The BTEX constituents detected above the TRNCC action level are below the TNRCC construction worker standard for benzene, (20,100 ug/Kg) and below the maximum concentration
detected at the site during the groundwater monitoring associated with the former LPST case. The groundwater level data obtained during this assessment indicated that the current groundwater
gradient is toward the north/northeast. Historical groundwater gradient at the site is toward the northwest. The topographic gradient at the site is toward the northwest. Groundwater
gradient typically mimics the topographic gradient. Banks Information Solutions was contracted to provide a water well search. A water well search covering a one-half mile radius indicated
two groundwater wells located in the search area. One well is located approximately one-quarter mile to the southwest the other is located just less than one half mile to the south.
These appear to be up-gradient and or cross-gradient from the site. Both wells are used for domestic purposes at depths of 320 feet and 800 feet respectively. Divestment Assessment 1-2

EA Engineering, Science. and Technology n. CHRONOLOGY OF EVENTS • October 10, 2001 -EA personnel requested line locates from utility company representatives and notified Exxon representatives
of upcoming activities. • October 12, 2001 -EA personnel conducted a site visit and marked locations for monitor wells and completed a receptor survey. • November 9, 2001 -EA cleared
the drilling locations by vacuum extraction to depths of approximately 2.0' where bedrock was encountered. Soil samples from surface to bedrock were collected via hand auger. • November
14, 2001 -EA supervised Total Support Services (TSS) in the installation of two 2" diameter monitor wells. Soil samples were collected during drilling operations and submitted to SPL
Laboratories of Houston, Texas for analyses. • November 16, 2001 -EA personnel gauged depth to groundwater, purged, and collected groundwater samples from MW-3, MW-4, MW -10 and MW -11.

EA Engineering, Science, and Techll(}/ogy III. TEXT A. SITE CHARACTERIZATION I FIELD INVESTIGATION RESULTS Exxon 6-0275 is a former retail gasoline station. Tne underground storage tank
(UST) system was removed prior to this assessment. The building was constructed in 1996 and the UST system was installed in 1991. The station previously dispensed four types of motor
fuel -regular unleaded, plus unleaded, supreme unleaded, and diesel. The site is a fonner LPST case (LPST NO. 109104) that was closed by the TNRCC in 1997. Banks Infonnation Solutions
was contracted to provide a water well search. A water well search covering a one-half mile radius indicated two groundwater wells located in the search area. One well is located approximately
one-quarter mile to the southwest the other is located just less than one half mile to the south. These appear to be up-gradient and or cross-gradient from the site. Both wells are used
for domestic purposes at depths of 320 feet and 800 feet respectively. (Appendix C). Land use in the vicinity of the site consists primarily of retail, commercial, and residential development.
B. SOIL ASSESSMENT On November 9,2001, EA cleared the drilling locations for subsurface structures by vacuum excavation to depths of approximately 2.0', wnere bedrock was encountered.
On November 14, 2001, EA supervised Total Support Services (TSS) during the installation oftwo groundwater monitor wells at the site. Soil samples were collected continuously from drill
cuttings until total the total depth of each borehole was achieved. Bedrock was encountered during clearing activities and sampling tubes were unable to be used. Soil samples from each
borehole were divided into five-foot intervals from ground surface to total depth. Soil sampling was perfonned while the monitor wells were being installed. Each sample was screened
with a Thenno Model 580B Organic Vapor Monitor (OVM). OVM readings ranged from 0 ppm to 227 ppm from the samples screened. Soil samples were collected from MW-1O at the 0' to 2', 2'
to 4' and 10'-15' intervals for laboratory analyses. Soil samples were collected from MW-ll at the 0' to 2',3' to 6' and 10'-IS' intervals for laboratory analyses. Soil samples were
analyzed for benzene, toluene, ethyl benzene, and xyJenes (BTEX), total petroleum hydrocarbons (TPH) and methyl tertiary butyl ether (MTBE). Laboratory analyses indicated total BTEX
concentrations ranging from <1.0 f,I.gIKg to 204.3 )!glKg in tne sample intervals that were analyzed. MTBE concentrations ranged from <1 )!glKg to 100 )!glKg in the sample intervals
tnat were analyzed. TPH concentrations were not detected in any soil samples analyzed. None of the soil samples collected during this assessment displayed BTEX or TPH concentrations
that exceeded TNRCC soil action levels (TNRCC 0621 (8-6-%), Release Determination Report Ponn). No action level for MIBE has been established by the TNRCC. Laboratory analyses for soil
samples are summarized in Table 1. Divestment Assessment

EA Engineering, Science, and Technology Regional Geology and Hydrogeology The geology of the north-central Texas region is composed of Cretaceous-age carbonates, sandstones and shales
that strike north-northeast and dip very gently to the east. The underlying geologic formations control topography, area drainage and soil types giving rise to specific physiographic
provinces cutting across this region. Quaternary-age alluvium and terrace deposits are found along the Trinity River and its tributaries. The geologic groups that are exposed in the
north-central Texas region from east to west (youngest to oldest) are the Navarro, Taylor, Austin, Eagle Ford, and Woodbine of the Upper Cretaceous Gulf Series and Washita, Fredricksburg,
and Trinity of the Lower Cretaceous Comanche Series. The site is located in southwestern Tarrant County, and is part of the Grand Prairie physiographic province. The Gnmd Prairie physiographic
province is underlain by a series of limestone layers alternating with marls of the Lower Cretaceous Washita Group. The terrain is characterized by flat upland surfaces underlain by
limestone and lower slopes derived from the softer interbedded marls which produce a terrace effect. The formations of primary hydrogeologic interest are the Woodbine, the Trinity Paluxy
and Twin Mountains Formations. The Woodbine Formation has been identified as a minor aquifer in Texas. It is composed of sandstone and ironstone with minor lignite and is 175 feet to
250 feet thick in the north-central Texas region. The water is fresh to slightly saline with zones of highly mineralized water due to high iron content. Water from the Woodbine Formation
is primarily used for small municipal, industrial, and irrigation supply. The Trinity Group is a major aquifer supplying many population centers in the north--central Texas region. Two
formations comprise the water bearing units of the Trinity Group. The uppermost Paluxy Formation and the lowermost Twin Mountains (Travis Peak) Formation are composed of fluvial and
deltaic sands and are separated by the Glen Rose Formation. In the north-central Texas region, these formations are each approximately 100 to 300 feet thick with the saturated thickness
increasing to the east. The water is used for municipal, domestic, and industrial supply, as well as for irrigation purposes. Site Geology According to the Geologic Atlas of Texas, Dallas
Sheet (Bureau ofEconomic Geology, The University of Texas at Austin, 1967, revised 1991) the site is underlain by the Upper Cretaceous Austin Chalk. The Austin Chalk is characterized
by fine-grained calcareous muds interbeded with chalk and some shale. The Austin Chalk is subdivided into upper and lower chalk members separated by a middle marl member. The Austin
Chalk is relatively resistant to weathering producing prominent escarpments. The chalk exhibits some fracturing and faulting. The Divestment Assessment 3-3 
EA Engineering, Science, and Technology maximum thickness is reported to be approximately 500 feet. According to the U.S. Department of Agriculture, Soil Conservation Service Soil Survey
for Dallas County, Texas (Daniel R. Coffee, Ralph H. Hill, D. D. Ressel, 1980) the site is underlain by soils classified as Stephen-Urban Land complex, 1 to 4 percent slopes. This map
unit consists of gently sloping, well-drained soils and areas of urban land. The Stephen soils makes up about 60 percent of this complex with areas where the surface is covered with
buildings and pavement making up another 30 percent, the remainder is made up or minor soils. The soils in these areas have been altered during urban development; therefore, it is not
feasible to identify them. The Stephen soils typically displayed a surface layer that is dark brown silty clay loam about 14 inches thick. Below this surface layer is white, platy, chalky
limestone. The hazard of erosion is moderate. Permeability is moderately slow and the available water capacity is very low. Runoff is medium and the shrink-swell potential as well as
corrosion potential is very high. Subsurface conditions were similar in monitor wells MW-10, and MW-11. Boring logs for the two monitor wells are presented in Appendix B. The lithologic
details were consistent throughout the site, with only slight variations between soil borings. C. GROUNDWATER ASSESSMENT The locations of the groundwater monitor wells were selected
to provide the maximum amount of subsurface information, to comply with TNRCC guidelines and ExxonMobil protocol, and to minimize any disturbance to the property. The site sits near
a hill, with the topographic gradient at the site toward the northwest. Groundwater gradient typically mimics the topographic gradient. According to the US.G.S. 7.5 minute Addison Quadrangle,
the area surrounding Exxon 6-0275 is gently sloping to the northeast. On November 16, 2001, groundwater samples were collected for laboratory analyses from MW10 and MW-Il and sentinel
wells MW-3 and MW -4. Laboratory analyses indicated total BTEX concentrations ranging from <1.0 I!gIKg in MW-4 to 1,522jLg/Kg in MW-II. TPH concentrations were not detected in any water
samples analyzed with the exception ofMW-ll, at a concentration of 6.8 mg/Kg. MTBE concentrations ranged from 1.2jLg/Kg in MW-4 to 43,000 I!gIKg in MW-II. No action level forMTBE has
been established by the TNRCC. Hydrocarbon concentrations in groundwater samples collected from MW-4 and MW-10 were below TNRCC action levels for groundwater (TNRCC 0621 (8-6-96), Release
Determination Report Form). The groundwater samples collected from MW-3 and MW-II were above TNRCC groundwater action levels for benzene. The groundwater sample collected from MW-11
was also above the TNRCC groundwater screening level for TPH. The BTEX constituents detected above the TRNCC action level are below the TNRCC construction worker standard for benzene,
(20,100 Divestment Assessment 3-4 
EA Engineering, Science, and Technology ugIKg) and below the maximum concentration detected at the site during the groundwater monitoring associated with the former LPST case. The topographic
gradient calculated during this assessment is toward the northeast. Historical groundwater gradient at the site is toward the northwest. The topographic gradient at the site is toward
the northwest. Groundwater gradient typically mimics the topographic gradient. Banks Information Solutions was contracted to provide a water well search. A water well search covering
a one-half mile radius indicated two groundwater wells located in the search area. One well is located approximately one-quarter mile to the southwest the other is located just less
than one half mile to the south. These appear to be up-gradient and or cross-gradient from the site. Both wells are used for domestic purposes at depths of 320 feet and 800 feet respectively.
No surface water bodies were observed in the immediate area of Exxon 6-0275. Tbe nearest surface water body is an intermittent stream that feeds into the Rawhide Creek located approximately
600 feet north of the site. The site is not located in a Wetlands area according the National Wetlands Inventory 1981 Addison Quadrangle map. Divestment Assessment 3-5

EA Engineering, Science, and Technology IV. CONCLUSIONS AND RECOMMENDATIONS Conclusions Groundwater monitor well (MW) installation at Exxon 6-0275 began on November 9, 2001 when EA cleared
each well location of utilities using vacuum excavation. The monitor well locations were selected using ExxonMobil protocol and a topographic map. MW-10 was installed at the southwestern
side of the site, west of the tankpit and southwest of the dispenser islands. MW-11 was installed at the northern side of the site, north of the tank pit and northeast of the dispenser
islands. Soil sampling was performed while the monitoring wells were being cleared and installed. Soil samples were collected from MW-I0 at the 0' to 2',2' to 4' and 10'-15' intervals
for laboratory analyses. Soil samples were collected from MW-ll at the 0' to 2',3' to 6' and 10' -IS' intervals for laboratory analyses. Two groundwater monitoring wells installed during
the former LPST case activities (MW-3 and MW-4) were also used to complete this divestment divestment assessment. MW-10 and MW-ll were installed to !Ctal depths of 15 feet. Groundwater
did significantly accumulate MW-11 within two hours after installation; however, MW-10 was dry. MW-10 and MW-ll were completed with 2.5 feet of solid two-inch diameter PVC riser. The
remainder of all wells were completed with factory slotted PVC screen. Soil samples were analyzed for benzene, toluene, ethyl benzene, and xylenes (BTEX), total petroleum hydrocarbons
(TPH) and methyl tertiary butyl ether (MTBE). Laboratory analyses indicated total BTEX concentrations ranging from <1.0 JA,g/Kg to 204.3 JA,g/Kg in the sample intervals that were analyzed.
MTBE concentrations ranged from <1 JA,g/Kg to 100 JA,g/Kg in the sample intervals that were analyzed. TPH concentrations were not detected in any soil samples analyzed. None of the soil
samples collected during this assessment displayed BTEX or TPH concentrations that exceeded TNRCC soil action/screening levels (TNRCC 0621 (8-6-96), Release Determination Report Form).
No action level for MTBE has been established by the TNRCC. Laboratory analyses for soil samples are summarized in Table 1. On November 16, 2001, groundwater samples were collected for
laboratory analyses from MW-10 and MW-11 and sentinel wells MW-3 and MW-4. Laboratory analyses indicated total BTEX concentrations ranging from <1.0 JA,g/Kg in MW-4 to 1,522 JA,g/Kg
in MW-11. TPH concentrations were not detected in any water samples analyzed with the exception of MW-II, at a concentration of 6.8 mg/Kg. MTBE concentrations ranged from 1.2 JA,g/Kg
in MW-4 to 43,000 JA,g/Kg in MW-ll. No action level for MTBE has been established by the TNRCC. Hydrocarbon concentrations in groundwater samples collected from MW-4 and MW-10 were below
TNRCC action levels for groundwater (TNRCC-0621 (8-6-96), Release Determination Report Form). Divestment Assessment 4-1 
EA Engineering, Science, and Technology The groundwater samples collected from MW-3 and MW-ll were above TNRCC groundwater screening levels for benzene. The groundwater sample collected
from MW-11 was also above TNRCC groundwater action levels for TPH. The BTEX constituents detected above the TRNCC action level are below the TNRCC construction worker standard for benzene,
(20,100 ug/Kg) and below the maximum concentration detected at the site during the groundwater monitoring associated with the former LPST case. The groundwater level data obtained during
this assessment indicated that the current groundwater gradient is toward the north/northeast. Historical groundwater gradient at the site is toward the northwest. The topographic gradient
at the site is toward the northwest. Groundwater gradient typically mimics the topographic gradient. Banks Information Solutions was contracted to provide a water well search. A water
well search covering a one-half mile radius indicated two groundwater wells located in the search area. One well is located approximately one-quarter mile to the southwest the other
is located just less than one half mile to the south. These appear to be up-gradient and or cross-gradient from the site. Both wells are used for domestic purposes at depths of 320 feet
and 800 feet respectively. Recommendations Analytical results of groundwater samples collected from MW-3 and MW-ll showed benzene concentrations above TNRCC action levels, and MW-11
showed a TPH concentration above the TNRCC screening leveL A Release Determination Report (RDR) has been completed, and should be submitted to the TNRCC to document current hydrocarbon
concentrations. As the site is a former LPST case, the TNRCC will issue a CARF indicating jf the LPST case will be re-activated after review of the RDR. Ifthe LPST case is re-opened,
the TNRCC will direct further corrective action. -------------...􀀭􀁾􀀮􀀭􀀭􀀭􀀭􀀭􀀭􀁟􀀺􀁣􀁟􀁟􀀭􀀭􀀭􀀭Divestment Assessment 4-2 
EA Engineering, Science, and Techn%gy V. QUALITY ASSURANCE /QUALITY CONTROL PROCEDURES A. SAMPLING PROCEDURES Soil samples are collected continuously throughout the boring of each monitor
well. Samples are collected using five foot split spoon cores, two foot split spoon cores, shelby tubes, or flight augurs. All sampling tools are steam cleaned prior to each use to prevent
any possible cross contamination. From each sample core, two soil samples are collected; one for screening with the OVM and the other for possible laboratory analysis. The OVM was calibrated
to a test gas mixtore of 100 parts per million (ppm) isobutlyene in air. Samples collected for OVM screening are stored in clean ziplock plastic bags and allowed to volatilize for at
least 10 minutes. Samples collected for possible laboratory analysis are stored in clean 250 ml glass jars and immediately packed on ice. For each monitor well, the soil samples corresponding
to tile interval with the highest OVM reading and the interval just above the water zone are retained for laboratory analysis. BTEX and TPH analysis are performed on each soil sample.
Ifleaded gasoline is or was available at the site, Total Lead or TCLP Lead analysis is also conducted on one composite soil sample for disposal purposes. Prior to groundwater sampling,
water levels in the monitor wells are measured with an ORS Interface Probe. Depth is measured from the top of casing to the nearest 0.01 foot as this electronic instrument detects the
air/water or airfhydrocarbonfwater interface. The probe is cleaned between monitor well measurements using methyl alcohol. The wells are developed following water level measurement.
The wells are bailed until three or four well volumes of water have been removed or until the well has been bailed dry. The developing bailer is cleaned with a series of methyl alcohol
and distilled water rinses. New cord is used to lower the decontaminated bailer into each well. All water removed from the monitor well is stored in a 55 gallon steel drum. Water generated
during well development and purging was processed on November 16, 2001 through a portable activated carbon treatment unit and discharged onsite. Groundwater samples are collected at
intervals ranging from one to 15 days afrer developing, depending on groundwater recharge rate. Samples are collected with a Voss brand Single Sample disposable bailer. The bailers are
wrapped in plastic until opened at the site, and new cord is used for each monitor well. The groundwater samples are collected in 40 ml glass VOAs and one liter sample jars and immediately
stored on ice. B.LABORATORYPROTOCOL EA Engineering uses only Laboratories that comply with EPA guidelines for laboratory procedures and protocol. Specific quality assurance/quality control

fax: Date Reported: 1211101 Matrix spike (MS) and matrix spike duplicate (MSD) samples are chosen and tested at random from an analytical batch of "like" matrix to check for possible
matrix effect. The MS and MSD will provide site specific matrix data only for lhose samples which ara spiked by the laboratory. Since the MS and MSD are chosen at random from an analytical
batch, the sample ChOsen for spike purposes mayor may not have been a sample submitted in this sample delivery group. The validity of the analytical procedures for which data is reported
in this analytical report is delennined by the Laboratory Control Sample (LCS) and the Method Method Blank (MB). The Laboratory Control Sample (LCS) and the Method B!ank (MB) are processed
with the samples and the MSJMSD to ensure method criteria are achieved throughout the entire analytical process. Any other exceptions associated with this report will be footnoted in
the analytical result page(s} or the quality control summary page(s). Please dQ not hesitate to contact us if you haye any questions or comments pertaining to this dala report. Please
reference the above Certificate of Analysis Number. This report shall not be reproduced except in full, without the written approval of the laboratory. The reported results are only

""ISIIng stale water well databases and addlUonal file data/records researeb conducted at T""a" regulatOf}' authorities. Submission ofdriller's log records upon completion of a drtlled
water well became mandatory In 19li6. The state ofT",,"" has processed Ihese records Into several different filing systems within two state regulatory authorities. The water welililes,
records and map loCations are maintained by the Texas Natural Reaou.... Cooaervation CommIsaionrrNRCC) and _ Texas Water DeVeIopnent Board(TWDB). Actual water well site locations ofIIIls
report are geocoded and geopIoIIed directly from tile drilling records, drilling scheduJes, and driller's logs and ma"" su_ed by the water well doll..and maintained at_two primary water

EA Engineering, Science, and Technology I. EXECUTIVE SUMMARY Exxon 6-0275 is a fonner retail gasoline outlet located at 4191 Belt Line Road, Addison (Dallas County), Texas. The site
is assigned Texas Natural Resources Conservation Commission (TNRCC) Facility ID No. 0026232. The station is also a fonner LPST site ID No. (109104). Underground storage tank (UST) removal
activities began on October 23,2001 and were completed on November 23,2001. The activities included the removal of four fiberglass UST used to store various grades of unleaded gasoline,
diesel, and associated product piping and dispensers. On October 26,2001 TNRCC Licensed UST Contractor Sunbelt Industrial Services (Sunbelt) removed three 10,000-gallon fiberglass UST's
and one 8,000-gallon fiberglass UST used to store various grades of unleaded gasoline and diesel. Between October 29, and November 8,2001, Sunbelt excavated and removed the seven dispenser
islands and associated product piping. EA Engineering, Science, and Technology, Inc. (EA) collected composite native soil samples during removal of the USTs and submitted the samples
to Southern Petroleum Laboratories (SPL) of Houston, Texas for laboratory analyses. Several of the native soil samples collected during UST system removal activities displayed hydrocarbon
concentrations that were above TNRCC soil action and screening levels, but less than the concentrations the site closed under. Product line trench LT-I-South and LT-3-North had TPH concentrations
of 192 mgfKg and 770 mgfKg, respectively. Dispenser islands NW-DI and Middle DI-West had TPH concentrations of490 mgfKg and 780 mgfKg respectively. The samples from the UST excavation
and dispenser island areas with the highest TPH concentrations were submitted for P AH analysis. P AH concentrations were below TNRCC action levels for any detected PAH constituents.
During tank excavation activities on October 26,2001, U.S. Filter Recovery Services, Inc. (U.S. Filter) removed approximately 14,850 gallons of water generated during excavation, de-watering
and UST rinsing activities. US Filter transported the rinse water to its disposal facility in Corsicana, Texas. Approximately 165 cubic yards of soil and fill generated during the excavation
of the line trenches and dispenser islands displayed a total petroleum hydrocarbons (TPH) concentration that exceeded TNRCC soil screening levels. This material was profiled, manifested,
and transported off-site for disposal at Allied Waste's BFI-Itasca Gardens Landfill in Itasca, Texas or the Waste management landfill in Ferris, Texas. The remaining pea gravel fill
and soil excavated during removal of the UST system was backfilled into the open excavations. Clean select fill was also imported to the site to bring the excavations at the site back
to original surface grade. F:\Pro)\E;uon\sdM·027MepoTts\I'EA Tank Excavation Report

Belt Line Road at Midway Road, Addison (Dallas County), Texas. The site is assigned Texas Natural Resources Conservation. Commission (TNRCC) Facility ID No. 0026232. The station is also
a fonner LPST site (ID No. 109104). Underground storage tank (UST) removal activities began on October 23, 2001 and were completed on November 23, 2001. The activities included the removal
of four fiberglass USTs used to store various grades of unleaded gasoline, diesel and associated product piping and dispensers. A copy ofthe construction notification fonn and TNRCC
receipt acknowledgement letter are located in Appendix A. B. SAMPLING PROTOCOL AND ANALYTICAL METHODS Nineteen composite samples of native soil were collected from the floor and/or walls
of the UST excavation, the product line trenches and dispenser island excavations (Table 1). 1). Six composite samples of excavated soil/fill were also collected for possible waste characterization
purposes (Table 1). Native soil samples collected during UST system removal activities were collected from freshly exposed soil surfaces and placed in clean laboratory supplied glass
sample jars with Teflon lids. Composite samples of excavated soil/fill were also placed in laboratory supplied jars with Teflon lids. The soil samples were placed in ice-chilled, clean,
laboratory-supplied coolers and delivered under chain-of-custody to Southern Petroleum Laboratories in Houston, Texas. Native soil samples collected from the walls and floor of the UST
excavation and the line trench and dispenser island excavations were analyzed for benzene, toluene, ethylbenzene and xylenes (BTEX-EPA Method 802lB), and total petroleum hydrocarbons
(TPH-TNRCC Method TX 1005). Stockpile samples of soil/fill removed from these excavations were also analyzed for BTEX and TPH. The soil sample collected from beneath the diesel UST,
as well as the sample with the highest TPH concentration, were analyzed for polynuclear aromatic hydrocarbons (PAR-EPA Method 8310). Copies of laboratory reports, chains-of-custody,
and QNQC documentation are included Appendix B. Original laboratory reports are on file at EA's office in Carrollton, Texas. C. REMOVAL ACTIVITIES AND ANALYTICAL RESULTS Unleaded Gasoline
and Diesel UST Removal On October 26, 2001 TNRCC Licensed UST Contractor, Sunbelt Industrial Services (Sunbelt), removed three 1O,000-gallon fiberglass UST and one 8,000 gallon fiberglass
UST used to store various grades of unleaded gasoline, and or diesel. Prior to removal of the USTs, U.S. Filter of Dallas, Texas rinsed each UST using a mixture of F:\Pro]\Exxon\sdtVi-0275\11.epOrls\
TEA 6 Tank Excavation Report 
EA Engineering, Science, and Technology detergent and water, and removed all rinse water and residual vapor from each UST, Following evacuation of hydrocarbon vapors from the tanks Sunbelt
monitored the atmosphere inside each UST for explosive conditions (photo 1). An 1.EL value of zero was measured in each UST. Sunbelt then removed all four USTs. Visual inspection of
each UST after removal indicated all USTs were in good condition with no evidence of damage or leaks prior to excavation, with the exception of the diesel UST that had been recently
damaged by ongoing underground utility work. An RDR documenting the damage was submitted by EA. The USTs were paint labeled with proper warnings, loaded onto flatbed trailers, immobilized
with straps, and transported to Sunbelt's yard located at 2415 Cullen Street, Fort Worth, Texas (Photo 3) for scrapping and disposal. After the USTs were removed from the site, the remaining
fill in the UST excavation was moved to expose the walls and floor of the tankpit (photo 4). One composite native soil sample was collected from each UST excavation wall (West Wall;
South Wall, North Wall, and East Wall) and four composite samples were collected from the UST excavation floor (Bottom North, Bottom North Middle, and Bottom South Middle and Bottom
South) (Figure 3). Fill removed from the UST excavation was temporarily stockpiled on site. After receiving analytical results the pea gravel fill was returned to the UST excavation
following removal of the four tanks. None of the native soil samples collected from the UST tank pit displayed hydrocarbon concentrations that were above TNRCC soil action and screening
levels. BTEX concentrations ranged from less than the limit of detection to 87.9 uglKg. TPH concentrations of ranged from less than the limit of detection to 78 mg/Kg. The sample from
beneath the diesel UST was submitted for PAH analysis. The PAH concentrations exhibited were below TNRCC action levels. Results of the laboratory analyses are shown in Table 1, and copies
of laboratory reports, chains-of-custody, and QAlQC documentation are included in Appendix B. Original laboratory reports are on file at EA's office in Carrollton, Texas. Excavation
of Product Piping Trenches and Dispenser Islands Sunbelt excavated seven dispenser islands and 11 product piping trenches between October 2 and November 8, 2001. After all product piping
and fill material was removed, composite native soil samples were collected from the floor and walls of the line trench excavations (LT-I through LT3 North and South, LT-4, LT-5, LT-6,
LT-7 and Vapor North LT) as well as each dispenser island excavation (NW DI, SW DI, NE DI, Middle DI-East, Middle DI-West and Diesel Dl) (Figure 3). Several ofthe native soil samples
collected during the product piping trenches and dispenser island removal activities dispJayed hydrocarbon concentrations that were above TNRCC soil action and screening levels, but
less than the concentrations the site closed under. Product line trenchLT-I-South andLT-3-North had TPH concentrations of 192 mglKg and 770 mg/Kg, respectively. Dispenser islands NW-DI
and Middle DI-West had TPH concentrations of F:\ProJ\Exxon\sdM..(J2751Reports\TEA 7 Tank Excavation Report 
EA Engineering, Sciellce, and Techn%gy 490 mglKg and 780 mglKg respectively. The samples from the UST excavation and dispenser island areas with the highest TPH concentrations were submitted
for PAH analysis. PAH concentrations were below TNRCC action levels. Results of the laboratory analyses are shown in Table I, and copies of laboratory reports, chainsof-custody, and
QAlQC documentation are included in Appendix B. Original laboratory reports are on file at EA's office in Carrollton, Texas. D. WASTE DISPOSITION On October 26,2001, three 10,000 gallon
fiberglass UST and one 8,000 gallon fiberglass UST were paint labeled with proper warnings, removed from the ground, loaded onto flatbed trailers, immobilized with straps, and transported
to Sunbelfs yard located at 2415 Cullen Street, Fort Worth, Texas. Upon arrival, the USTs were cut into pieces and scrapped. A copy of the Certificate of Destruction is located in Appendix
C. Soil I Fill material Excavation of Gasoline USTs Pea gravel fill removed during excavation of the gasoline USTs was temporarily stockpiled on site. After receiving analytical results
the pea gravel fill was returned to the UST tank pit. Excavation of Existing Product Piping Trenches and Dispenser Islands Approximately 165 cubic yards of soil and fill generated during
the excavation of the line trenches and dispenser islands displayed a total petroleum hydrocarbons (TPH) concentration that exceeded TNRCC soil screening levels. This material was profiled,
manifested, and transported off-site for disposal at Allied Waste's BFI-Itasca Gardens Landfill in Itasca, Texas and Waste Management's landfill in Lewisville, Texas on November 23,2001.
UST Contents and UST Tankpit Water During tank excavation activities on October 26,2001, U.S. Filter removed and transported approximately 14,850 gallons of water produced during de-watering
and UST rinsing to its disposal facility in Corsicana, Texas. A Copy of the U.s. Filter manifest is included in AppendixC. 􀁆􀀺􀁬􀁐􀁲􀁯􀁪􀁜􀁅􀁸􀁸􀁯􀁮􀁾􀁤􀁎􀀵􀂷􀀰􀀲􀀷􀀵􀀧􀀧􀁊􀀿􀁥􀁰􀁯􀁮􀁳􀁜􀁔􀁅􀁁􀀠8

the chain of custody twice. SPL received sample 10 'NW 01' which was not listed on the chain of custody. Per Marl< Lach, via phone conVersation, on November 14, 2001, SPL analyzed the
sample for BTEX by method B021 and TPH by TNRCC method TX1005. Matrix spike (MS) and matrix spike duplicate (MSO) samples are chosen and tested al randem from an anelytlcal batch of
'like' matrix to check for possible matrix effeeL The MS and MSO will provide site specifIC matrix data only for those samples which ara spiked by the laboratory. Since the MS and MSD
are chosen at random hom an analytical batch, the sample chosen for spike purposes mayor may not have been a sample submitted In this sample delivery group. The validity of the analytical
procedures for which data Is reported in thIs analytical report Is detennined by the L_ratory Control Sample (LCS) and the Method Blank (MB). The Laboratory Control SamPle (LCS) and
the Method Blank (MS) are processed with the samples and the MSIMSD to ensure method criteria are achieved throughout the entire analytical process. Your sample ID 'NW DI" (SPL 10: 011
1 0375-01) was randomly selected for u.eln SPL's quality control program for the Total Petroleum HydrocartlCns (TPH) anatysis by TNRCC Method TX 1005. The MS andlor MSD recoveries were
outside of the advisable quality control limits for CS-G12 end Tolal TPH (C6-C35) (Batch ID: 16103) due to matrix interference. A Laboratory Control Sample (LCS) was analyzed as a quality
control check for the analytical batch and all recoveries were within acceptable limits. Your sample 10 'Middle 01 Wesr (SPL ID: 01 11037S-(6) was randomly selected for use in SPL's
quality control program for the Polynuclear Aromatic Hydrocarbons analysis by SW846 Method 8310. The MS andlor MSO reeovenes were outside of the advisable quality control limits for
several constituents (Batch 10: 16266) due to matrix Interference. A Laboralory Control Sample (LCS) was analyzed as a quality control Check for the analytical batch and all recoveries
were within acceptabfe limits. Any other exceptions associated with this raport will be foolnoted in the analytical resutt pagels) or the quality control summary pagels). Please do not

we respond to your June 6th letter regarding the Exxon Tiger Mart located at the intersection of Midway Road and Belt Line Road in Addison. As you recall, one of the store's underground
storage tanks was recently damaged by contractors working within the Town's right-of-way. Your letter requests a written response outlining Exxon's intended course of action regarding
the existing tanks and the Town's request that the curb and pavement be setback in compliance with the previously approved site plan. We wish to assure you that Exxon is working diligently
toward a resolution of these matters. Discussioris regarding the . tanl<s and site are currently being held with the landlord and store operator. Furthermore, Exxon is seeking direction
from the TNRCC regarding the damaged tank. Finally, all these rnattersare complicated by the 1996 .. condemna:tion proceedings in which the Town acquired the right ofway under which
a portion of the tankis apparently buried. As you might imagine, providing a specific course of action has proven difficult given the complexity of the situation and number of interested
parties. 
Mr. Luke Jalbert July 17, 2001 Page·2. We are confident that all issues will be resolved within the next three weeks and that a detailed course of action will then be available. Exxon
appreciates your patience and looks forward to addressing your concerns. ely, '-.......􀀢􀀧􀁌􀁏􀁁􀁓􀀮􀀯􀁴􀁾􀀠 DF/bk
