I sent the email below to Glen Canyon staff on May 19th hoping they would bring fuel prices back into compliance before Memorial Day weekend. I never heard back so resent it on the 29th and still have not received a response. I still have not seen fuel prices adjusted. I feel like it’s important for the public to be aware as it’s resulting in Aramark overcharging thousands of dollars in fuel with no accountability as it will directly affect anyone using the on lake fuel during their vacations. This is the second time in the past 2 years I’ve seen them overcharging on fuel (first time was the entire 2023 season which was not brought into compliance until September of that year).

Dear NPS Staff,
I hope this message finds you well.
I was recently on the lake and noticed that current fuel prices at Bullfrog Marina seem significantly higher than expected. Based on prior communication from NPS in 2023, I understand that the Direct Comparability Method is used to determine allowable fuel pricing at on-lake marinas. To ensure I’m interpreting the situation correctly, I wanted to share some updated information and request clarification on a few points.
2023 Method Reference:
As previously explained, fuel pricing was determined by comparing Bullfrog to the following marinas:
$5.706 + $0.5564 tax + $0.11 UPT = $6.373/gallon
Updated Price Check (May 2025):
After contacting these same marinas directly, I found the following updated pricing:
Updated allowable price for Bullfrog:
$5.59 + $0.5564 tax + $0.11 UPT = $6.26/gallon
However, Bullfrog is currently charging $6.73/gallon, which appears to exceed the allowable amount by $0.47 per gallon. On May 15, I purchased 162.580 gallons, potentially resulting in an overpayment of $74.41 (receipt attached).
I would greatly appreciate your assistance with the following:

2023 Method Reference:
As previously explained, fuel pricing was determined by comparing Bullfrog to the following marinas:
- Lake Havasu Marina, AZ – $5.999 (minus tax $0.376) = $5.623
- Don Pedro Marina, CA – $6.286 (minus tax $0.560) = $5.726
- Bartlett Lake, AZ – $5.999 (minus tax $0.376) = $5.623
- Roosevelt Lake, AZ – $6.229 (minus tax $0.376) = $5.853
$5.706 + $0.5564 tax + $0.11 UPT = $6.373/gallon
Updated Price Check (May 2025):
After contacting these same marinas directly, I found the following updated pricing:
- Lake Havasu Marina, AZ – $4.59 (minus assumed tax $0.376) = $4.21
- Don Pedro Marina, CA – $7.89 (minus assumed tax $0.560) = $7.33 (Premium only)
- Bartlett Lake, AZ – $5.99 (minus assumed tax $0.376) = $5.61 (Premium only)
- Roosevelt Lake, AZ – $5.59 (minus assumed tax $0.376) = $5.21 (Premium only)
Updated allowable price for Bullfrog:
$5.59 + $0.5564 tax + $0.11 UPT = $6.26/gallon
However, Bullfrog is currently charging $6.73/gallon, which appears to exceed the allowable amount by $0.47 per gallon. On May 15, I purchased 162.580 gallons, potentially resulting in an overpayment of $74.41 (receipt attached).
I would greatly appreciate your assistance with the following:
- Please confirm whether the same Direct Comparability Method is still in use. If so:
a. Could NPS ensure that Bullfrog’s fuel pricing is brought back into compliance?
b. I respectfully request a refund from Aramark for the noted overpayment, and a review of any similar transactions that may have occurred earlier this season to ensure others receive the same reimbursement. - Octane Discrepancy: Bullfrog provides only Regular Unleaded (87), whereas three of the four comparison marinas supply only Premium (91) fuel. This presents an issue of apples-to-oranges comparison. Premium fuel generally costs more, so if Bullfrog is only selling Regular Unleaded, the pricing should reflect that lower cost category. Continuing to benchmark Bullfrog’s 87 Octane fuel against marinas that exclusively sell 91 Octane appears to artificially inflate the allowable pricing. I would ask that:
- Either Bullfrog begin offering 91 Octane to match the comparables, or
- The fuel price benchmark be adjusted downward to reflect the lower-grade fuel currently sold at Bullfrog.
- Comparables & Methodology: Roosevelt Lake remains a significant outlier in the benchmark group. In my research, I checked fuel prices at seven other on-water marinas in Arizona, Nevada, and New Mexico, and found the average price for 91 Octane was $4.94/gallon, which is significantly lower than Roosevelt and Don Pedro. Could you please share:
- The criteria and methodology used to select these four marinas as comparables.
- The date of the last update to the comparison group and whether a revision is planned soon.
- A copy of the Rate Administration Guide or relevant documentation used to govern fuel pricing at Lake Powell.
- Propane Tank Pricing: Bullfrog currently charges $54.25 per exchange tank, which is over double the cost of exchanges in Salt Lake City. Could you share the approved rate structure or guidelines for propane pricing at concession-operated marinas?
