>>> (It was 17.6 million barrels in 1982).
We haven't built any plants in the last 30 years, but we have expanded capacity at existing, more efficient plants. The current 16.9 billion bbd capacity is higher than at any point in almost 25 years. The peak capacity year was 1981 at 18.6bbd. Much of the decline in U.S. refining capacity resulted from the 1981 deregulation (elimination of price controls and allocations), which effectively removed the major prop from underneath many marginally profitable, often smaller, refineries.
