It is also the smallest of the storage regions tracked, without the same interstate pipeline access that links the Gulf Coast to the Midwest and the East Coast, so propane moves more on local gas processing, rail and truck than on a single trunk line. That leaves this region's stocks more exposed to local production swings than the other PADDs. Stocks build from spring through summer and draw down through the heating season on the same calendar as the rest of the country, and the five-year band is the reference for whether this combined region carries its usual cushion into the colder months. ## About this data - Source: EIA Weekly Petroleum Status Report - Series: Propane and propylene ending stocks - Basis: Primary storage, excluding propylene at terminal - Geography: PADD 4-5 (Rockies and West Coast) - Unit: million barrels - Calculation period: Weekly ending stocks - Last observation: Jul 17, 2026 - Update frequency: Weekly --- Cite: PADD 4-5 (Rockies and West Coast) propane stocks: 4.5 million barrels, 8% above the 5-yr median (The Fill Line's same-week 5-year median, not EIA's published five-year average).
