Refinery Scale
Chevron Pascagoula at 330,000 bpd generates substantial hazmat freight. Combined with smaller Mississippi River terminals, the state produces enough fuel to support dedicated tanker fleets.
Delta Seasonality
Agricultural chemical demand in the Delta peaks sharply in spring (March-May). Carriers who serve the Delta during planting season can earn premium rates, but summer and winter volumes are considerably lower.

Hazmat Shipping in Mississippi — FAQs
What is Mississippi's largest hazmat shipper?
The Chevron Pascagoula refinery at 330,000 barrels per day is the state's dominant hazmat freight generator. Fuel products from this refinery distribute throughout the Southeast via tanker truck and pipeline.
How does hurricane season affect Mississippi hazmat?
Gulf hurricanes can shut down the Pascagoula refinery and coastal chemical facilities for days to weeks. Pre-storm fuel staging creates demand spikes. Post-storm recovery generates emergency hazmat needs for fuel delivery and chemical cleanup.
Is agricultural chemical hauling viable in Mississippi?
During spring planting season (March-May), ag-chem hauling in the Delta is very profitable. Outside of planting season, volumes drop significantly. Most carriers combine Delta ag-chem work with Gulf Coast petrochemical loads for year-round utilization.
