Dear Ms. Chavez,
On behalf of 7-Eleven, Inc. (7-Eleven), Stantec Consulting Services Inc. (Stantec) has prepared the following
report to document post no further action (NFA) work at Speedway Store No. 9444 (the Site), located at 874
East 1300 South, Salt Lake City, Utah (Figure 1). 7-Eleven acquired Speedway in 2021, and the Site is also
referred to as 7-Eleven Store No. 47165. The Utah Department of Environmental Quality (UDEQ), Division
of Environmental Response and Remediation (DERR) refers to the Site as Facility ID 4000765 and Release
Site MWK.
The scope of work documented herein is authorized by the DERR under WP&B MWK-12, which was
approved on September 11, 2024. The post NFA scope documented herein included electrical supply
disconnect, disassembly and removing the remediation system, remediation enclosure demolition, monitoring
and remediation well abandonment, remediation piping and electrical conduit grouting and plugging, and
concrete and asphalt surface restoration.
Stantec contracted Pacific West Environmental (Pacific West) to complete the on-site post NFA work. Stantec
provided oversite of all on-site work. A summary of post NFA work is included below.
Scope of Work
Electrical Service Disconnection
On August 28, 2024, Stantec was on-site to document disconnection of the remediation system electrical
service by Rocky Mountain Power (RMP). RMP disconnected the three-phase electrical service at the
transformer and left the wiring to be removed by Pacific West. RMP removed the electrical meter and
switch box from the metal H-frame.
On December 10, 2024, Pacific West removed the electrical wiring from the underground conduit between
the remediation enclosure and the electrical switch box and pulled the remaining wire down the electrical pole
from the electrical meter base. All wire was recycled. The convenience store manager requested that the
metal H-frame that supported the electrical meter and switch box be left in place to serve as a bike rack for
customers.

874 East 1300 South, Salt Lake City, Utah
Facility ID 4000765, Release Site MWK

The electrical conduit at the remediation enclosure was cut flush with the concrete pad. The remaining
aboveground electrical conduits at the metal H-frame were cut below grade. Grout was gravity fed into both
legs (between the metal H-frame and the remediation enclosure and between the metal H-frame and the
utility pole) of the remaining underground electrical conduits. When grout daylighted at the remediation
enclosure, that leg of the electrical conduit was considered effectively plugged. After a sufficient amount of
grout was placed in the electrical conduit between the metal H-frame and the utility pole to fill the underground
portion of that leg of the electrical conduit, it was capped underground. Stantec has submitted an additional
service requested for RMP to remove the remaining above ground electrical conduit from the utility pole.
Remediation Equipment Disassembly
On November 26, 2024, Stantec oversaw the disassembly of the remediation system inside the remediation
enclosure by Pacific West. The disassembled equipment was secured inside the remediation enclosure
overnight. On November 27, Stantec and Pacific West returned to demolish the remediation enclosure and
load and transport the remediation system components to be made available for the Utah State Surplus
(Surplus) Property auction.
The equipment could not be transported to and stored at the Surplus facility as Surplus did not have adequate
employees on duty during the holiday week. As of the writing of this report, the equipment is being stored at
Pacific West’s yard located at 5751 North Droubay in Erda, Utah. The equipment will be posted for auction
by Surplus upon receipt of updated pricing for the skid mounted soil vapor extraction/catalytic oxidizer unit.
If the equipment is not sold during the Surplus auction period, Pacific West will dispose of the equipment. If
necessary, Stantec will prepare a work plan amendment to account for the additional contractor costs and
disposal fees for Pacific West to dispose of the equipment.
Well Abandonment
On December 10 and 12, 2024, Pacific West abandoned all wells associated with the Site. All monitoring
and remediation wells were abandoned under the direction of a Utah Division of Water Rights licensed well
driller (Justin Health, license number 974) in accordance with the Utah Administrative Rules for Water Well
Drillers, R655 4 14.
Monitoring wells and the nested soil vapor well (SV-1) were abandoned by cutting the asphalt or concrete to
remove the well monument, pulling the casing from the subsurface, backfilling the borehole with bentonite
chips, hydrating the bentonite in place, and resurfacing with either asphalt, concrete, or grass plug as
appropriate. The casing could not be fully removed from monitoring wells MW-3 and MW-7 due to breakage.
Approximately the top five feet of casing were removed with the remaining casing backfilled as previously
described.
Soil vapor extraction (SVE) wells and the air sparge well (AS-1) were abandoned similarly to the monitoring
wells except the top one foot of casings were cut and removed with the remainder of casing left in place. The
remediation piping entered each remediation well approximately two feet below ground surface; therefore,
the remediation well casings could not be fully removed as the remediation piping was left in place.

Remediation Piping Abandonment
On December 10 and 12, 2024, Pacific West abandoned all underground remediation piping. Grout was
pumped into each of the remediation pipes at the remediation enclosure concrete pad. Grout was pumped
into one remediation pipe at a time until it was observed at the corresponding remediation well at which point
the remediation pipe was considered effectively plugged.
Off-Site Monitoring Well MW-4
As of the writing of this report, off-site monitoring well MW-4 remains in place. Stantec, 7-Eleven, and the
DERR made numerous attempts to persuade the property owner at 860 East 1300 South to allow Stantec
and Pacific West access to the property to complete abandonment activities for MW-4. The property owner
did not approve access to their property. 7-Eleven has provided the property owner with a bill of sale and
release of indemnity agreement (bill of sale) to complete in order to transfer all cost, maintenance, liability,
observance of Utah laws related to the well to the property owner. A copy of the bill of sale is included as
Attachment 1. Upon further communication with the property owner, it is Stantec’s opinion that they do not
intend to execute the bill of sale and do intend to continue to deny access to the property.
Limitations and Certification
The conclusions in the Report titled Post NFA Work – Site Closure Report, Speedway Store No. 9444 (7-
Eleven Store No. 47165) are Stantec’s professional opinion, as of the time of the Report, and concerning the
