RE: Well Abandonment Report
Fastrac Sinclair (former Tesoro #40)
12 West 3900 South, South Salt Lake City, Utah
Facility ID No. 4001070, Release Site No. MJK
Terracon Project No. 61087215
Dear Mr. Thompson:
Terracon Consultants, Inc. (Terracon) has prepared this letter report to document the
abandonment of the groundwater Monitoring Wells, Injection wells, and Sparge Ports
associated with Release Site MJK at the Fastrac Sinclair (formerly Tesoro #40) site located
at 12 West 3900 South in South Salt Lake City, Utah.
A total of 53 wells (including 23 monitoring wells and 30 injection wells) and three sparge
ports were previously installed. These wells and sparge ports were used for investigation,
monitoring, and remediation of the former Release MJK, which has attained No Further
Action status. This report documents the completion of well abandonment activities in
accordance with guidance at UAC R655-4-14. Additionally, previously accumulated
monitoring well purge water, stored in two partially filled 250-gallon totes, was profiled for
disposal at the E.T. Technologies, Inc (ET). waste disposal facility. Following waste profile
review and approval, the purge water and totes were subsequently removed from the site
for disposal under the ET waste profile.
Terracon and an ET crew, of two, mobilized to the site on October 28, 2024 to begin initial
abandonment procedures. These initial procedures included identification of well size and
depth to assess the required amount of bentonite pellets and chips needed to fill the well
anulus and complete resurfacing at the former well location.
All wells (monitoring wells, injection wells, and sparge ports) associated with the release
and site remediation activities were identified and properly abandoned. Well abandonment
procedures included:
measuring well total depth and groundwater elevation
introduction of bentonite pellets into the well to a point at/or above the water table

Facilities |Environmental | Geotechnical | Materials 2
removal of the well surface completion (flush mount collar and lid)
removal of the upper or all-well casing (where practical)
introduction of bentonite chips above the bentonite pellets to near surface
addition of water to hydrate the bentonite chips
resurfacing the former well flush mount location with materials (concrete, asphalt, or
soil) to match the existing ground surface at that location
All work performed to complete the well abandonments was conducted between October 28
to October 31, 2024. A map showing the former well locations is provided as Attachment 1.
Attachment 2 provides Table 1 that lists all of the abandoned wells and sparge ports with
dates of final abandonment. A photographic log of the site conditions and well abandonment
procedures is provided as Attachment 3.Attachment 4 provides documentation of the
profiling and disposal of the stored purge water by E.T. Technologies.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
T8 Sample(s) received past/too close to holding time expiration.
