The extra petroleum will come from northeastern oil reserves in New Jersey and Maine The sale of the government-owned stock was mandated by Congress in the spending bill passed in March this year.

“The Biden-Harris administration is laser-focused on lowering prices at the pump for American families, especially as drivers hit the road for summer driving season,” Energy Secretary Jennifer M. Granholm said in a White House statement.

The volumes will be allocated in quantities of 100,000 barrels, which the White House says “will ensure a competitive bidding process that both fuel retailers and terminal holders can participate in,” to ensure fuel “can flow into local retailers” before the July 4 holiday. A U.S. barrel contains 42 gallons.

The White House also said the quantities will be “sold at competitive prices, helping lower costs for American families and consumers.”

“This builds on other actions by President Biden to lower gas and energy costs — including historic releases from the Strategic Petroleum Reserve and the largest-ever investment in clean energy,” Karine Jean-Pierre, the White House press secretary, said in a statement.
