What is a PADD?

EIA's petroleum districts — the regions behind every regional DOE diesel price

When a fuel-surcharge schedule says “DOE Midwest” or “PADD 3,” it means one of EIA's petroleum districts:

New England (PADD 1A): $5.399/galCentral Atlantic (PADD 1B): $5.370/galLower Atlantic (PADD 1C): $5.107/galMidwest (PADD 2): $4.988/galGulf Coast (PADD 3): $4.942/galRocky Mountain (PADD 4): $4.935/gal — lowest this weekWest Coast less California: $5.362/galCalifornia: $6.471/gal — highest this week1A$5.3991B$5.3701C$5.107PADD 2$4.988PADD 3$4.942PADD 4$4.9355 ex-CA$5.362CA$6.471
Average on-highway diesel by EIA region, week of July 20, 2026 — darker shading = more expensive; click a region. PADD 5 includes AK and HI (counted in West Coast); East Coast (PADD 1) is 1A+1B+1C combined.

Every region links to its own weekly price page with full history:

Why regions differ: state fuel taxes (largest single factor — California's are the country's highest), distance from Gulf Coast refining, and regional fuel specifications. The spread is visible every week in the national table.

FAQ

What does PADD stand for?

Petroleum Administration for Defense District. The five districts were drawn in World War II to ration and move fuel; EIA kept them because seven decades of petroleum statistics are organized around them.

What PADD is my state in?

PADD 1 is the East Coast, split into 1A (New England), 1B (Central Atlantic: DE, DC, MD, NJ, NY, PA), and 1C (Lower Atlantic: FL through WV). PADD 2 is the Midwest — it stretches from Ohio to Oklahoma and includes Tennessee and Kentucky. PADD 3 is the Gulf Coast (TX, LA, NM, AR, MS, AL). PADD 4 is the Rockies (CO, ID, MT, UT, WY). PADD 5 is the West Coast plus AK, HI, AZ, and NV. The full state lists are in the table on this page.

Is there a weekly diesel price for my state?

Only if your state is California. EIA publishes weekly retail diesel for the U.S. average, the PADDs and their East Coast sub-districts, and California alone. For every other state, the closest official weekly number is the PADD average — sites advertising weekly prices for all 50 states are estimating.

Which region should my fuel surcharge use?

Whatever the contract says. The U.S. national average is the most common trigger; some regional fleets and dedicated lanes peg to a PADD instead, which tracks local pump prices more closely but is less liquid as a reference. The contract's named series governs either way.
