Record-Low Distillates Stocks Leave East Coast Exposed

Record-Low Distillates Stocks Leave East Coast Exposed Miguel E. Andujar DTN Refined Fuels Market Reporter DAVENPORT, FL (DTN) -- The U.S. East Coast fuel market is heading into a major test in the coming weeks after distillates inventories hit their lowest levels on record last week, leaving the region particularly vulnerable and with little cushion ahead to a major planned maintenance outage at Irving Oil's Saint John refinery. The Energy Information Administration's Weekly Petroleum Status Report released Wednesday (9/2) showed that PADD 1 distillates stockpiles fell 1.7 million bbl, or 8%, to 19.3 million bbl during the week ended August 28, the lowest level on record since the agency began tracking weekly inventories in 1990. Last week's drawdown leaves the region with a thin supply cushion just days before Irving Oil plans a 75-day turnaround at its 320,000-bpd Saint John refinery in New Brunswick, Canada. PADD 1 is especially vulnerable to disruptions in outside supply because the region holds just 5.1% of U.S. refining capacity. According to EIA data, East Coast operable crude distillation capacity was at 928,300 bpd as of January 1, compared with 18.2 million bpd nationwide. As a result, the region depends heavily on refined-product movements from the Gulf Coast, primarily through the Colonial Pipeline system, as well as tanker and barge shipments and foreign imports. This year, however, those replacement flows have weakened due to the global supply shortage driven by the Middle East conflict. PADD 3-to-PADD 1 distillate pipeline movements fell from 842,000 bpd in January to 615,000 bpd in June, EIA data showed. Colonial Pipeline's Line 2 carries distillates from the Houston, Texas, area to Greensboro, North Carolina, where barrels can continue north through Line 3 toward Linden, New Jersey. Supplies are expected to remain limited as U.S. Gulf Coast refiners have opted to export distillates to cover the global diesel shortage. PADD 3 distillate exports increased from 1.09 million bpd in January to 1.48 million bpd. Over the same period, PADD 3-to-PADD 1 pipeline flows dropped from 842,000 bpd to 639,000 bpd, leaving fewer Gulf Coast barrels to supply the East Coast region. Additionally, the economics for shipping ULSD from Houston to Linden have weakened sharply. DTN market data showed that the NYH ULSD average premium over Gulf Coast ULSD has gradually declined from 7.48cts gallon in May to 2.55cts in August. Those spreads were below Colonial Pipeline's 7.98cts gallon Houston-to-Linden tariff before product loss allowances, line-space costs and other expenses. The spread turned negative on several sessions in late August, including a 4.75cts gallon ULSD Gulf Coast premium over the same product traded in the New York Harbor on August 21. Fuel buyers do not have many options as the product is scarce even in the imports market. According to federal data, the four-week average for PADD 1 distillate imports fell from 200,000 bpd early on the year to 88,000 bpd during the four weeks ended August 21. Supply concerns are especially pronounced in New England, where distillate inventories have fallen to about 2.3 million bbl heading into the fall heating season. The Saint John refinery, one of the Northeast's largest external fuel suppliers, is scheduled to begin a 75-day turnaround September 8. Based on the refinery's capacity and typical distillate yields, Saint John could account for an estimated 3% to 6% of total PADD 1 distillate supply, with its importance considerably greater in New England. The latest EIA data also showed distillate inventories in the Lower Atlantic, or PADD 1C, fell 17% on the week, indicating the draw was spread across more than one East Coast market. With limited refining capacity of its own, record-low inventories, fewer Gulf Coast barrels moving north, weaker import flows and upcoming maintenance at Saint John, PADD 1 is entering the fall increasingly dependent on an improvement in replacement supply before winter heating demand accelerates.
