PADD 1B (Central Atlantic) propane stocks

Delaware, Maryland, New Jersey, New York and Pennsylvania make up the Central Atlantic, the most populous of the three East Coast storage areas this site tracks and the one with the most varied supply. Import and storage terminals around the New York Harbor and the Delaware River sit alongside gas processing tied to the nearby Marcellus and Utica fields, so this region draws on both Appalachian production and the Gulf Coast pipeline network rather than one supply line alone. Stocks build over the warmer months and draw down as heating demand rises, the same calendar the rest of the East Coast follows. Because this sub-region carries the biggest share of East Coast demand, its five-year band tends to move the whole PADD 1 reading, and a level below normal here is felt across the region.

This area holds the largest storage volumes on the East Coast, so its direction usually sets the direction of the PADD 1 total above it. EIA counts propane and propylene in primary storage, in thousand barrels: barrels at terminals, in pipelines and at gas processing plants. Secondary storage, the dealer and household tanks that hold winter supply closest to the customer, never appears in the series and is typically fullest in the fall, just as this line starts down. The figure publishes Wednesdays at 10:30 a.m. Eastern in the Weekly Petroleum Status Report and covers through the prior Friday. It is a weekly estimate, revised later against monthly data.
