About PADD 4-5 (Rockies and West Coast) propane stocks
Unlike the rest of the areas on this site, the Rockies and West Coast are reported as one combined region because EIA does not publish a separate propane stocks figure for PADD 4 or PADD 5. 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.
