Re: Work Plan for System Decommissioning and Well Abandonment, IVB-38
Jenkins Oil. 2753 West Santa Clara Drive Santa Clara, Utah
Facility ID: 6000046, Release ID: IVB, MQB

Dear Mrs. Johnson:

Rockwell Solutions, Inc. submits this work plan to abandon monitoring wells for the above-referenced
site. PST Fund payment claims will reference this work plan and the specific tasks itemized below.

INTRODUCTION

The subject site was a fueling facility and terminal located in Santa Clara, Utah. During underground
storage tank (UST) removal activities in January 1995, contamination was detected and a release was
reported. The site was assigned release number IVB.

In June 2010 a release was discovered from the aboveground storage tank system within the existing
groundwater contaminant plume from release IVB. Approximately 4,860 cubic yards of soil were
removed from the Jenkins Oil property and the adjacent Clover Patch property. An air sparge (AS)
and a soil vapor extraction (SVE) remediation system were installed on both properties to abate further
migration of free product and to remove hydrocarbons from the soil and groundwater. A thermal
oxidizer unit was installed to treat the SVE vapors. The system was expanded in 2013. The system
was shut down in February 2017 when vapors were no longer being removed from the subsurface. In
April 2017, six deeper monitoring wells were installed to replace or help define and monitor the plume.
Groundwater monitoring continued until the releases were closed on August 29, 2023. The purpose of
this work plan is to properly abandon the remaining monitoring wells and decommission the
remediation system associated with the releases.

SCOPE OF SERVICES

Well Abandonment
Thirty-nine two-inch diameter and ten four-inch diameter monitoring/remediation wells remain at the
site. See Figure 1. Because the wells are less than thirty feet deep, the abandonment does not have to
be performed by a licensed well driller. Each well will be abandoned by Rockwell Solutions
personnel. The well can will be removed, the well will be filled with bentonite chips and cut off below
grade, the surface will be patched with asphalt or dirt/gravel to match the surrounding surface.

There are seventeen remediation wells on the subject property or on the adjacent Clover Patch property
that need to be abandoned. These wells are located within remediation boxes that are approximately
13” by 24” and 18” deep. Rockwell Solutions will abandon the wells with bentonite and Spackman
Enterprises will cleanly remove the boxes, backfill the hole, and, resurface the hole with either asphalt,
topsoil and grass, or gravel, to match the surrounding area.

Two-inch remediation wells:

Also, five vapor wells were installed for the site investigation:
VW-1
VW-2
VW-3
VW-4
VW-5

System Decommissioning
The remediation system included an air compressor, a vacuum blower, a thermal oxidizer, and all of
the associated electrical conduit, boxes, and equipment. Spackman Enterprises will remove and
dispose of all remediation equipment.

Petroleum Storage Tank Trust Fund Work Plan Approval Application and Agreement
for Workplan No. IVB-38

Facility Name: Jenkins Oil, Address: 2753 West Santa Clara Drive, Santa Clara, Utah ID No. 6000046
Release ID IVB (“Release”)
Owner/Operator, responsible party or other person seeking PST Fund reimbursement: Jenkins Oil (“Claimant”)
Certified Consultant or other person performing remedial action concurrently with this Work Plan under the
supervision of a certified consultant Rockwell Solutions, Inc. (“Contractor”)

In submitting Revised Work Plan IVB-38, for the above referenced Release IVB for approval, the Claimant and the
Contractor collectively, the “Parties” represent and agree to the following.

Definitions
“Contractor” means the person identified as such above.
“Claimant” means the person identified as such above.
“Executive Secretary” means the Executive Secretary of the Solid and Hazardous Waste Control Board (UST).
“Fund” means the Petroleum Storage Tank Trust Fund.
“Release” means the release identified above.
“State” means the State of Utah including its agencies, officers, employees, volunteers and specifically, the Division of
Environmental Response and Remediation, the Executive Secretary of the Solid and Hazardous Waste Control Board
(UST) and the Petroleum Storage Tank Trust Fund.
“Work Plan” means the work plan identified above.

1) The key personnel, for which qualifications are submitted under R311-207-3(c), are: David S. Hansen

2) The Claimant acknowledges that the Claimant is required to obtain a payment bond from the Contractor
under section 14-2-1 of the Utah Code. If the Claimant fails to do so, the Claimant is liable to each person
who performed labor or services or supplied equipment or materials (“Subcontractors”) in the event the
Contractor does not pay the subcontractors, even if the Claimant has paid the Contractor. See Utah Code
section 14-2-2. The Claimant acknowledges and agrees that the Fund will not reimburse the Claimant for
such Subcontractors’ claims for payment against the Claimant if the Fund has already made payment to the
Claimant or Contractor. The Claimant understands that the premium paid for a payment bond is
reimbursable. Therefore, the Claimant:

a. has required the Contractor to obtain 100 percent payment bond through a United States
Treasury-listed bonding company, and attached a copy, or;
b. requests that PST fund reimbursement checks be made jointly to the Claimant, the Contractor and
to the Subcontractors designated by the Parties, but waives all claims and remedies against the
State if the Fund checks are not made as described above, or;
c. has obtained other equivalent assurance and waives all claims and remedies against the State if the
equivalent assurance does not adequately protect the Claimant. The equivalent assurance is
described as follows: Rockwell Solutions, Inc., Agreement for Professional Services Contract
between Jenkins Oil and Rockwell Solutions, Inc..

3) The Parties agree that the Contractor shall have no cause of action against the State for payment. The Parties
acknowledge and agree that the State is not a party to any contract with the Claimant or the Contractor for
reimbursement from the Fund in the execution of this Work Plan, except to the extent provided by a contract
signed by the Executive Secretary. Instead, the Claimant’s reimbursement is governed by the Utah
Underground Storage Tank Act and the Utah Underground Storage Tank Rules and the Contractor is entitled
to reimbursement solely under the contract he has with the Claimant.

4) The Parties agree that they will use a subcontracting method consistent with the requirements of R311-207.

5) The Parties agree that as a condition of performing the work under the Work Plan, the Contractor shall carry
the insurance specified in R311-207-3(c)(5). The Contractor represents that certificate of insurance
documenting the required insurance is attached or that a current certificate is on file with the Executive
Secretary and has been provided to the Claimant. The Parties assume the risk and responsibility of ensuring
that the appropriate insurance coverage is in place.

6) The Parties agree that payments from the Fund shall be limited to amounts that are customary, legitimate,
reasonable and consistent with R311-207. Unless the Parties and the Executive Secretary have entered into a
written Pay-for-Performance agreement, the Parties acknowledge that payments will be for actual time and
