The Secretary may participate in a federally owned storage project “in an amount equal to not more than 50 percent of the total cost of the federally owned storage project,” (4007(b)(2)) and may participate in a State-led storage project “in an amount equal to not more than 25 percent of the total cost of the State-led storage project” (4007(c)(1)).
