R99 RENEWABLE DIESEL DELIVERY & CALIFORNIA CONSTRUCTION FUELING FAQ

Since January 1, 2024, California’s In-Use Off-Road Diesel-Fueled Fleets Regulation has required covered fleets to use R99 or R100 renewable diesel in covered vehicles, subject to specified exemptions. When ordering construction fuel, specify R99 or R100 renewable diesel rather than simply requesting “diesel” or “clean diesel.”

Yes. Dogpatch Biofuels offers R99 renewable diesel delivery and on-site equipment fueling for construction projects in San Francisco and the surrounding Bay Area, including San Jose and the East Bay. Contact us with your jobsite address, equipment list, estimated fuel volume, and delivery schedule to discuss service options.

Yes. Our mobile fueling service delivers fuel directly to equipment at your construction site or staging area. Also called wet hosing or wet fueling, direct-to-equipment fueling helps reduce off-site fuel trips and keeps equipment ready for the next shift.

Covered rental equipment operating in California is included in the renewable diesel requirement unless an applicable exemption applies. Coordinate with your rental provider and fuel supplier before equipment arrives so the required fuel is available throughout the rental period.

Covered fleets must retain documentation demonstrating compliance with the renewable diesel requirement, including purchase dates and fuel volumes, for three calendar years after each transaction. When arranging delivery, request documentation identifying the fuel supplied and confirm any additional reporting requirements in your project specifications.

No. R99 can satisfy the applicable renewable diesel fuel requirement, but fleet compliance also involves equipment eligibility, reporting, recordkeeping, and other obligations. Fuel receipts do not replace a valid CARB Certificate of Reported Compliance.

For projects involving equipment covered by the Off-Road Regulation, prime contractors and public works awarding bodies generally must obtain valid Certificates of Reported Compliance for the contracted fleet and its listed subcontractors before entering into a new or renewed contract. These certificates must be retained for three years after project completion. Additional obligations apply to prime contractors.

Yes. Dogpatch Biofuels offers 250-gallon and 500-gallon fuel cube rentals with fuel delivery options for construction projects. Contact us to discuss capacity, placement, delivery access, and refueling frequency. Before installation, confirm applicable fire, spill-prevention, and permitting requirements for your site.

No. Renewable diesel does not replace required emissions testing, registration, or reporting. Clean Truck Check generally covers non-gasoline vehicles over 14,000 pounds GVWR operating on California public roads and highways, subject to exemptions. Your road-going construction trucks and off-road equipment may fall under different CARB programs.

Renewable diesel can reduce lifecycle greenhouse gas emissions compared with petroleum diesel. The reduction depends on the fuel’s feedstock, production pathway, and blend. For project reporting, request supporting fuel information and use the accounting method required by the project owner. Lifecycle reductions should not be presented as an identical reduction in tailpipe CO₂ emissions.

Provide your jobsite address, required fuel specification, estimated gallons per delivery, equipment types, project duration, and preferred fueling times. Let us know whether you need direct-to-equipment fueling or a fuel cube, and identify any access restrictions or project documentation requirements.Call 415-484-5344 to discuss R99 renewable diesel delivery and construction site fueling with Dogpatch Biofuels.
