The $0.5780 Lever Sitting in Your Yard Tank
Rocky Mountain diesel rose for the third straight week. This issue covers the tax on the diesel your off-road equipment burns, and how to stop paying the part you don't owe.
In Colorado, a gallon of clear diesel carries $0.5976 in federal and state tax and fees. Dyed diesel, the red fuel made for equipment that never runs on a public road, leaves $0.5780 of that off the bill. If your loaders, generators, and skid steers fill from the same clear diesel as your plated trucks, you are paying road tax on fuel that never touches a road.
Below: how to find that money, keep it legal, and claim back some of what you already paid.
What TNDS is building: Three builds shipped. First, the TNDS site is rebuilt: the service ladder now shows real prices, there is a page written for government buyers, and every release gets automatic accessibility scans before it goes live. Second, the off-road diesel tax calculator from this issue is live and free on the Pipeline Punks Build Studio. Third, the PetroStack demo console is up: a read-only walk through a distributor pricing and dispatch system, running on sample data so you can click around without seeing anyone's real numbers. Hit reply if you want a tour of any of them.

Stop Paying Road Tax on Iron That Never Sees a Road
Colorado off-road equipment burning clear diesel pays $0.5780 per gallon in tax it does not owe. How to stop paying it, and how to claim some of it back.
In a lot of yards on the Front Range, one tank of clear diesel fuels everything: the plated service trucks, the excavator, the light towers, the generator. It's simple to run, and every gallon pays the full road tax, whether it goes down the highway or into a trench.
The math is per gallon. Clear diesel in Colorado carries the $0.2440 federal excise, the $0.2050 state special fuel excise, a $0.0600 Road Usage Fee, a $0.0700 Bridge and Tunnel Impact Fee, and about $0.0186 in small environmental, fuel impact, and PFAS fees. That is $0.5976. Dyed diesel skips everything except $0.0010 of the federal tax and those small fees, so it costs $0.5780 per gallon less in tax.
Run it at 1,000 gallons a month of off-road burn. That is $578 a month, $6,936 a year, before you subtract whatever premium your supplier charges for dyed fuel and any local tax your city adds. Get the dyed quote in writing before you count the savings.
Going forward, sort the iron first. A unit qualifies for dyed fuel only if it is not plated for road use and it never fills from a tank that also fuels plated vehicles. If one tank does both jobs today, it cannot switch. Put in a second tank, then switch. The worksheet in this week's Free Drop walks the sort unit by unit.
Looking back, you can claim some of what you already paid. Colorado refunds the state tax on clear diesel used off-road: you apply for a refund permit on form DR 7189, then claim on form DR 7118. Claims must be filed within 12 months of purchase, purchases under 20 gallons do not count, and you can file at most once per calendar quarter. On the federal side, the credit for nontaxable use of undyed diesel is $0.2430 per gallon on Form 4136. Your CPA decides what qualifies and files it. Your job is to hand them clean gallons by month, by invoice, and by unit.
Dyed diesel in a plated vehicle on a public road normally carries a federal penalty of $1,000 or $10 per gallon, whichever is greater, and the $1,000 floor goes up $1,000 for every prior penalty. That penalty is paused right now. Under the October 5 executive order, the IRS is not imposing it from October 1 through December 31, 2026, and Colorado has paused state enforcement through year-end. The federal tax on that road use is deferred, not forgiven. Keep your tanks separate and labeled, tell your drivers why, and plan for the normal rules coming back January 1.
Put July 1, 2027 on the calendar. That day the Colorado Road Usage Fee goes to $0.0700 and the Bridge and Tunnel Fee to $0.0800, which adds $0.0200 per gallon to what dyed diesel saves.
Blue Collar AI: This week I had Claude check every rate in this issue against the Colorado Department of Revenue and IRS pages, line by line, with links. It flagged that Colorado cut its environmental response surcharge in October, from $0.0125 to $0.009375 per gallon, and it turned up the IRS pause on dyed diesel penalties that changed the Command Drop. I still opened every source myself before anything went in.
Field Build
A fuel and lubricants distributor was pricing, dispatching, and tracking compliance out of a stack of spreadsheets and paper. Prices were right because a few experienced people kept them right by hand every morning, and that only works while those people are in the building. Over the past few months we built PetroStack, a pricing and operations system that sits on top of the tools they already own.
| Area | Before | After |
|---|---|---|
| Daily price sheet | Supplier prices copied by hand every morning from an email into several workbooks | One live price sheet that updates itself from the supplier's daily price email, with dashboards by delivery zone. In production since October 21. |
| Trust in the numbers | An old workbook nobody wanted to touch because nobody was sure what it did | A parity test that runs the new system against the old workbook. 58 of 58 checks match. |
| Dispatch | Printed sales orders and a whiteboard | A dispatch board fed by the open-orders export from their ERP, with a manual fallback when the import is late |
| Compliance dates | Inspection and test dates scattered across binders and inboxes | One tracker that flags what is due. Tank truck vapor tests that would land in summer get pulled forward so they finish by April 30. |
What changed: The ERP stays the system of record. PetroStack reads from it and from the supplier email, does the pricing math the same way the old workbook did, and passed a side-by-side test against that workbook before anyone relied on it. The people who used to key prices by hand now review them.
Time invested: About 12 weeks of embedded work, built in stages so each piece went live and earned trust before the next one started.
Signal Check
- Rocky Mountain diesel rose for a third straight week. The EIA retail average for No. 2 diesel in the Rocky Mountain region hit $6.5210 per gallon for the week of October 26, up $0.0990 from the week before and up $0.2540 since October 5. So what: if your fuel surcharge is indexed to this benchmark, update the table before your November invoices go out, and check that your customer contracts let you pass it through. (Source: [EIA, October 26](https://www.eia.gov/dnav/pet/hist/LeafHandler.ashx?n=PET&s=emd_epd2d_pte_r40_dpg&f=w))
- EIA raised its diesel forecast for this year and next. The October Short-Term Energy Outlook puts the 2026 U.S. retail diesel average at $5.1900 per gallon, up from $5.0700 in last month's forecast, and 2027 at $4.4900, up from $4.4000. September averaged $6.2900, driven by higher crude prices and wider refining margins. So what: if you are building a 2027 budget or quoting fixed-price work into next year, use the new number, not last month's. The next outlook comes out November 10. (Source: [EIA Short-Term Energy Outlook, October 6](https://www.eia.gov/outlooks/steo/))
- Colorado cut one fuel fee in October and has two increases set for July. The environmental response surcharge dropped to $0.009375 per gallon this month, down from $0.0125. On July 1, 2027 the Road Usage Fee rises to $0.0700 and the Bridge and Tunnel Impact Fee to $0.0800 per gallon. So what: update the tax table in your pricing and invoicing now for the October cut, and put a reminder on the calendar for July. The July step adds $0.0200 per gallon to clear diesel.

Tool of the Week
[Google Apps Script](https://developers.google.com/apps-script)
Apps Script is the code layer inside Google Workspace. In the Field Build above, it reads the supplier's daily price email each morning, writes the numbers into the live price sheet, and logs every run. That replaced copying prices from the email by hand. The gotcha: if the supplier changes the layout of the attachment, a script like this can fail without an error and keep yesterday's prices. Build in a header check that stops the run and emails you when the file doesn't look right.
