The Strategic Petroleum Reserve and Refined Product Reserves: Authorization and Drawdown Policy

Summary

Congress authorized the Strategic Petroleum Reserve (SPR) in the Energy Policy and Conservation Act (EPCA, P.L. 94-163) to help prevent a repetition of the economic dislocation caused by the 1973-1974 Arab oil embargo. The Department of Energy (DOE) manages the SPR, which comprises five underground storage facilities, solution-mined from naturally occurring salt domes in Texas and Louisiana. The Energy Policy Act of 2005 (EPAct) authorized SPR expansion to a capacity of 1 billion barrels, but physical expansion of the SPR has not proceeded beyond 727 million barrels—its inventory at the end of 2010. In addition, a Northeast Home Heating Oil Reserve (NHOR) holds 2 million barrels of heating oil in above-ground storage.

EPCA authorized drawdown of the Reserve upon a finding by the President that there is a “severe energy supply interruption.” Congress enacted additional authority in 1990 (Energy Policy and Conservation Act Amendments of 1990, P.L. 101-383) to permit use of the SPR for short periods to resolve supply interruptions stemming from situations internal to the United States. The meaning of a “severe energy supply interruption” has been controversial. EPCA intended use of the SPR only to ameliorate discernible physical shortages of crude oil.

The government had ended the practice of purchasing crude oil to fill the SPR in 1994. In 2000, the Department of Energy began acquiring SPR oil through royalty-in-kind (RIK) in lieu of cash royalties paid on production from federal offshore leases. In May 2008, Congress passed legislation (P.L. 110-232) ordering DOE to suspend RIK fill for the balance of the calendar year unless the price of crude oil dropped below $75/barrel. Crude oil prices spiked to $147/barrel in the summer of 2008 and then sharply declined, allowing a resumption of fill. These activities have brought the SPR essentially to its current 727 million barrel inventory. The current Secretary of the Interior recently announced his intention to terminate the RIK program.

Congress approved $205 million for the SPR in FY2009, including $31.5 million to continue SPR physical expansion activities. DOE has evaluated a site in Richton, MS, as a possible location for an additional 160 million barrels of capacity, but set aside any further expansion plans. The FY2010 Energy and Water Appropriations Act (P.L. 111-85), which provides $243.8 million for the entire SPR program, included $25 million for expansion activities and $43.5 million for purchase of a cavern at Bayou Choctaw to replace a cavern posing environmental risks. The act also prohibits SPR appropriations from being expended to anyone engaged in providing refined product to Iran, or assisting Iran in developing additional internal capacity to refine oil.

Historically, the use of the SPR has been tied to a physical supply shortage, which normally would manifest itself, in part, as a price increase. The original intention of the SPR was to create a reserve of crude oil stocks that could be tapped in the event of an interruption in crude supply. However, price was deliberately kept out of the President’s SPR drawdown authority because of concerns about what price level would trigger a drawdown, and that any hint of a price threshold could influence private sector and industry inventory practices. The original intention of the SPR was to create a reserve of crude oil stocks that could be tapped in the event of an interruption in crude supply.

The Government Accountability Office recently observed that the proportion of crude oil grades in the SPR has been growing less compatible with the heavier grades of crude oil that U.S. refineries have been upgrading to handle. This finding has raised questions about the SPR’s effectiveness during a long-term oil disruption involving heavy oil.
