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. ## Common questions ### Is PADD 1B (Central Atlantic) propane inventory high or low right now? PADD 1B (Central Atlantic) propane stocks stood at 5.3 million barrels as of Aug 28, 2026, 5% below the 5-year median of 5.5 million barrels for this point in the year. A level under the band means a thinner cushion than usual going into the draw season. ### What is the 5-year average for PADD 1B (Central Atlantic) propane stocks? 5.5 million barrels for this week of the year, measured as the 5-year median rather than a flat annual average, because propane inventories swing hard by season and a single yearly number would compare a March level against an August one. [Propane inventories and the 5-year average](/guides/propane-inventories-and-the-5-year-average) explains how to read the band. ### How do propane stock levels affect prices? Inventory is the cushion between winter demand and the physical supply that can reach a market in time. When stocks run under their seasonal band going into October, buyers competing for a thinner cushion bid up the [Mont Belvieu spot price](/spot/mont-belvieu), and delivered prices follow with a lag as dealers replace barrels at the higher cost. A comfortable build has the opposite effect: it absorbs a cold snap without a price response. ### When are PADD 1B (Central Atlantic) propane inventories typically lowest? The Central Atlantic bottoms out in February or March. It holds the largest storage volumes on the East Coast, so its direction usually sets the direction of the PADD 1 total above it. ## About this data - Source: EIA Weekly Petroleum Status Report - Series: Propane and propylene ending stocks - Basis: Primary storage, excluding propylene at terminal - Geography: PADD 1B (Central Atlantic) - Unit: million barrels - Calculation period: Weekly ending stocks - Last observation: Aug 28, 2026 - Update frequency: Weekly --- Cite: PADD 1B (Central Atlantic) propane stocks: 5.3 million barrels, 4.7% below the 5-yr median (The Fill Line's same-week 5-year median, not EIA's published five-year average).
