Re: Corrective Action Plan

12000 Big Cottonwood Canyon Release ID: OHY
Salt Lake City, Utah

Dear Mr. Johnson:

Rockwell Solutions, Inc. submits this corrective action plan (CAP) to excavate soil and dewater
contaminated groundwater at the above-referenced site.

INTRODUCTION

The site is the fueling location for vehicles and equipment at the Solitude Ski Resort. The fueling
system consists of one 8,000-gallon underground storage tank (UST) containing diesel fuel, and a
2,000-gallon aboveground storage tank containing gasoline. There is one dispenser at the site. A
site map is provided as Figure 1. Diesel fuel was observed leaking at the dispenser and was
reported as a release to DERR on May 31, 2023.

The objective of the corrective action is to excavate accessible contaminated soil and remove
impacted groundwater from the excavation.

SCOPE OF SERVICES

Public Notice
Solitude Mountain Ski Resort will post the public notice for their employees. No other properties
would be directly affected by the corrective action.

Excavation
The proposed area of excavation is shown on Figure 1. The estimated area is based on results
from the subsurface investigation. The depth of excavation is estimated to be eight to nine feet.
The estimated volume of soil to be removed is approximately 270 cubic yards. The excavation
area is shown on Figure 1. The dispenser will need to be removed and replaced.

2
Soil confirmation samples will be collected in the excavation in accordance with DERR guidelines.
Soil samples will be collected from the bottom of the excavation and at the approximate depth of
the groundwater table smear zone on the excavation walls, estimated to be between seven to eight
feet below grade. Samples will be submitted to a Utah-certified laboratory for analysis of MTBE,
benzene, toluene, ethylbenzene, xylenes, and naphthalene (MBTEXN) and total petroleum
hydrocarbons-gasoline range organics (TPH-GRO) using EPA Method 8260b, and TPH-diesel
range organics (TPH-DRO) using EPA method 8015b.

Soil Disposal
Soil will be hauled to the ET Technologies soil disposal facility in Salt Lake City.

Dewatering
Groundwater in the excavation will be pumped out into a frac tank. The groundwater in the
frac tank will be treated by air sparging using a large compressor. After laboratory analysis
confirms that the frac tank water is less than ISLs, it will be discharged into the onsite sewer.

Backfill
Imported, clean, structural fill and roadbase will be placed back into the excavation.

Reports
A final excavation report will be prepared documenting excavation activities and analytical results.

SCHEDULE

Excavation, backfill, and groundwater treatment activities will last approximately one week.

Petroleum Storage Tank Trust Fund Work Plan Approval Application and Agreement
for Workplan No. OHY-1

Facility Name: Solitude Mountain Ski Resort , Address: 12000 Big Cottonwood Canyon, Salt Lake City, Utah
ID No. 4001332
Release ID OHY (“Release”)
Owner/Operator, responsible party or other person seeking PST Fund reimbursement: Solitude Mountain Ski Resort
(“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 OHY-1, for the above referenced Release OHY 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 Solitude Mountain Ski Resort 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.

The Division of Environmental Response and Remediation (DERR) is planning to oversee the
remediation of petroleum-contaminated soil and groundwater at the above site. The environmental
consultant for this project is Rockwell Solutions, Inc.

Diesel fuel was observed dripping from the dispenser at the Solitude Mountain Ski Resort maintenance
shop. Soil and groundwater contamination were defined to the area around the dispenser.

The selected corrective action is to excavate contaminated soil around the former dispenser and to
remove and treat impacted groundwater from the excavation.

Tasks will include the following:

1) Excavate approximately 270 cubic yards of soil from the dispenser area. See attached figure
2) Haul off and dispose of the impacted soil
3) Dewater the excavation, storing the impacted groundwater in a 18,000-gallon frac tank
4) Treat the groundwater in the frac tank with air sparging to remove hydrocarbons
5) Discharge treated water to the sewer under a sewer discharge permit

Proposed Schedule
Excavation, backfilling, compaction, and groundwater treatment will take approximately one week to
complete.

A copy of the Corrective Action Plan prepared for this site is available at the DERR in Salt Lake
City (address below; office hours 8:00 a.m. to 5:00 p.m., Monday through Friday). For additional
