Dear Mrs. Johnson:

Rockwell Solutions, Inc. submits this work plan and budget addendum to cover additional corrective
action activities as per work plan OLF-2 at the above referenced site.

Petroleum Storage Tank Trust Fund Work Plan Approval Application and Agreement
for Workplan No. OLF-2, Amendment 1

Facility Name: Rally Stop #8, Address: 10 E Center Street, Panguitch, UT
ID No. 6000053
Release ID OLF (“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 Work Plan OLF-2, Amendment 1, for the above referenced Release OLF 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
